How to master PLC from scratch (I)Fully automatic can making machine

PLC in the eyes of people who now understand, is indeed a relatively simple thing, after all, it belongs to the application type of secondary programming development.But as a zero – based beginners, to learn PLC, or to pay a certain amount of time to explore.Must first understand PLC is the relay circuit of the software, and the nature is to draw on the computer relay circuit diagram, this is the basis of it, so before learning PLC, you must be a little electrician foundation, to understand and use the use of a relay circuit, this is very important, after all, the PLC software is to simulate the hardware circuit.

 

Beginners master PLC program upload and download, this is the first step.

Because the PLC peripheral circuit has been installed, as long as a PLC Y point such as Y4 set, Y4 corresponding lights will be lit up, with universal can be measured to an output contact signal.Mitsubishi is total Yang, as long as the public end of the PLC COM met some X point, such as X1, the X1 will be light, and inside the PLC have X1, the quantity of state, the state will become a high level, to let the X1 this normally open point to connect to an intermediate relay coils of M1, M1 will be “charged”, M1 control normally open contacts will be off, the relay control circuit and offline.So when you’re programming, it’s exactly the same thing as if you were drawing a trapezoid below the line.If a beginner understands this point, he is on the threshold.

4. Welding

316 stainless steel has good welding performance.All standard welding methods are available for welding.When welding, 316Cb, 316L or 309Cb stainless steel filler rod or electrode can be used for welding according to the purpose.In order to obtain the best corrosion resistance, the welding section of 316 stainless steel needs to be annealed after welding.If 316L stainless steel is used, no post-weld annealing is required.

5. Mechanical properties

Austenitic stainless steel has the lowest yield of all steel.Therefore, in terms of mechanical properties, austenitic stainless steel is not the best material for the stem, because the diameter of the stem will increase to ensure a certain strength.The yield point cannot be improved by heat treatment but can be improved by cold forming.

6. Magnetic

Because of the wide application of austenitic stainless steel, people are under the false impression that all stainless steel has no magnetism.Austenitic stainless steels are generally understood to be non-magnetic, as is the case with hardened-forged steels.But the 304 treated by cold forming is somewhat magnetic.For cast steel, 100% austenitic stainless steel is not magnetic.

7. Low-carbon stainless steel

The corrosion resistance of austenitic stainless steel comes from the chromium oxide coating formed on the metal surface.If the material is heated to 450 ℃ to 900 ℃ high temperature, the structure of the material will change, along the edge of crystal form of chromium carbide.In this way, no chromium oxide protective layer can be formed on the edge of the crystal, which leads to the reduction of corrosion resistance.This corrosion is called intergranular corrosion.

8. Why does stainless steel rust?

Why does stainless steel rust?When the stainless steel tube surface appears brown rust spot (point), people feel surprised: think that “stainless steel is not rust, rust is not stainless steel, may be steel problems”.In fact, this is a one-sided view of the lack of understanding of stainless steel.Stainless steel will rust under certain conditions.

Stainless steel has the ability to resist atmospheric oxidation, that is, rust, but also has the ability to contain acid, alkali, salt in the medium is corrosion resistance, that is, corrosion resistance.However, the corrosion resistance of steel varies with its chemical composition, protective condition, service condition and environmental media type.For example, 304 steel pipe has absolutely excellent anti-rust ability in the dry and clean atmosphere, but it will soon rust if moved to the coastal area in the sea fog containing a large amount of salt.The 316 pipe performed well.Therefore, not any kind of stainless steel, in any environment can resist corrosion, not rust.

316 and 316L stainless steels are molybdenum-containing stainless steels.The molybdenum content of 316L stainless steel is slightly higher than that of 316 stainless steel.Due to the molybdenum in steel, the steel is superior to 310 and 304 stainless steels in overall performance. 316 stainless steels have a wide range of USES under high temperature conditions when the concentration of sulfuric acid is lower than 15% and higher than 85%.316 stainless steel also has good chloride erosion properties, so it is commonly used in Marine environments.The maximum carbon content of 316L stainless steel is 0.03. It can be used for welding purposes where annealing is not possible and where maximum corrosion resistance is required.

1. Corrosion resistance

The corrosion resistance of 316 stainless steel is better than that of 304 stainless steel.In addition, the 316 stainless steel is resistant to Marine and corrosive industrial atmospheres.

In general, 304 stainless steel and 316 stainless steel in terms of chemical corrosion resistance is not much different, but in some specific media under the difference.Initially developed for 304 stainless steel, in particular cases, the material of Pitting Corrosion, Pitting Corrosion) is more sensitive.Adding an additional 2 to 3 percent of molybdenum can reduce this sensitivity, resulting in 316.In addition, these additional molybdenum can reduce the corrosion of certain thermoorganic acids.

316 stainless steel has almost become the standard material in the food and beverage industry.Due to the worldwide shortage of molybdenum and the higher nickel content in 316 stainless steel, 316 stainless steel is more expensive than 304 stainless steel.

2. Heat resistance

316 stainless steel has good oxidation resistance for intermittent service under 1600 c and continuous service under 1700 c.In the range of 800-1575 degrees, it is best not to continuous action 316 stainless steel, but in the temperature range outside the continuous use of 316 stainless steel, the stainless steel has good heat resistance.The carbide resistance of 316L stainless steel is better than that of 316 stainless steel, which can be used in the above temperature range.

3. Heat treatment

Annealing in the 1850-2050 temperature range, then rapid annealing, then rapid cooling.316 stainless steel shall not be hardened by overheating.

Tin can Deep drawing process analysis(tin cans production line)

Tin can Deep drawing process analysis(tin cans production line)  Deep drawing is a cold stamping process in which flat blank or semi-finished blank is deep drawn into an open hollow part by means of a mould.Drawing process can be made into the shape of products: cylindrical, gateway, spherical, conical, rectangular and other irregular open hollow parts.Drawing process combined with other stamping process, can produce complex shape parts, such as blanking process and drawing process combined with blanking compound die.  1. Deformation process of deep drawing  In deep drawing, the blank of the middle plate is first compressed by the blank holder, and the punch goes down, forcing the material (flange part) under the blank holder to generate plastic deformation and flow into the gap between the convex and concave dies to form the side wall of the cylinder.  2. Various drawing phenomena  1) corrugate  When drawing deep, the tangential compressive stress of the flange part is large enough to exceed the anti-instability ability of the material, and the flange part of the material will become unstable and swell, which is called wrinkling.Wrinkling is one of the main causes of waste products in deep drawing process. Normal deep drawing process is not allowed.The pressure of the common pressure ring holds down some materials of the flange to prevent wrinkling.  2) cutting margin  Due to uneven die clearance, thickness change, unequal friction resistance, inaccurate positioning and materials, mechanical properties of directivity, etc., resulting in the drawing part of the high and low, for the high requirements of the drawing part, need to add a cutting process.  3) calculation of blank size  It is mainly based on the principle of volume invariance and the variation of wall thickness in drawing.The principle of equal surface area between workpiece and blank before and after drawing is called equal area method.  4) factors affecting the drawing coefficient  A. mechanical properties of materials  B.

can production line servo motors and applications

Now, more and more servo motors are used in the equipment of can making.The popularization of servo motor greatly reduces the transmission system of the equipment and makes the control more convenient, fast and accurate.So what is a servo motor?Here is a popular science.

Servo motors, also known as execution motors, are used as execution elements in the control system to convert the input voltage control signal into the output angular displacement and angular velocity on the axis to drive the control object.Its biggest features:

The rotor rotates immediately with control voltage and stops immediately without control voltage.The direction and magnitude of the control voltage determine the direction and speed of the shaft.Can be divided into dc servo motor and ac servo motor.The motor consists of a stator, a rotor, an encoder and a housing.The speed can be controlled by changing the control voltage.The main function of the driver is to output the control voltage proportional to the given signal, receive the speed and position signal of the encoder, and I/O signal interface.

Ac servo motors should be used in general automatic control applications as far as possible.Dc servo motor or other special control motor, such as linear motor, should be used in the occasions of high speed regulation and control accuracy.According to the working mode and the conditions of the common ancestor environment, different types of structure are selected, such as frequently starting and stopping occasions using the hollow cup rotor structure of the servo motor, such as the speed requirements for more balanced occasions using large inertia servo motor.Power selection is not economical, too small motor overload and damage.For servo motors in continuous operation, the selected power shall be equal to or slightly greater than the power of the production machinery.For short-time working servomotors, the selected power may be equal to or slightly less than the power of the production machine, because a transient overload is allowed during operation.

The core of the stator is formed by the inner grooved silicon steel sheet, which generates a magnetic field by rotating. The rotor is subject to the action of the rotating magnetic field and thus rotates with the rotating magnetic field.An encoder is a device that compiles signals or data and converts them into signals that can be used for communication, transmission, and storage.It is installed in the rear end of the motor, and its turntable is coaxial with the motor.

Future of metal printing industry: a review of the development trend of metal printing technology

As one of the four major packaging materials, metal packaging ranks behind paper packaging and plastic packaging in terms of scale, and takes the lead over glass packaging at the same time.In 2017, there were more than 1,500 metal packaging and printing enterprises.The following technological trends will drive the transformation and upgrading of the industry and ultimately shape the future of plastic metal printing.

1. Printing equipment trend: multi-color high-speed, environmental protection and energy saving, high level of automation control

Metal printing capacity is seriously excess, it can be predicted that the future of traditional two-color printing will gradually exit the stage of history, and multi-color high-speed, environmental protection and energy saving, as well as high level of automation control of the printing press will occupy the absolute advantage.At present, the printing speed in intermittent feeding mode cannot exceed 6000 sheets per hour. Therefore, the realization of high-speed continuous feeding has become the goal pursued by printing equipment enterprises.

2. Application of new technologies

Although metal digital proofing compared to the traditional proofing used before, digital proofing on paper greatly improved the efficiency, but there is always a color difference between the paper and iron samples.The digital metal proofing technology has achieved a breakthrough from digital to metal samples, reducing the deviation between paper and metal samples, shorten the proofing time, the future can be based on the establishment of metal printing color management system.

3. Green raw and auxiliary materials

As the national environmental protection policies and regulations become stricter, more green, environmental protection, energy saving and low emission materials will obviously be favored by the metal printing industry.Uv-curable materials with the rapid development of multi-color UV printing, UV ink consumption has already exceeded the traditional ink, the future will continue to rise.Compared with external coating materials, coated materials can adopt relevant technologies to achieve zero VOCs emissions, while internal coating is fraught with difficulties in this respect.

4. Environmental protection and energy saving

With the increasingly stringent national environmental protection policies, metal packaging enterprises should pay attention to this issue.It is suggested to scientifically evaluate the existing production process and equipment, and determine a reasonable environmental protection treatment method, so as to achieve the goal of energy conservation and environmental protection, in line with the policy requirements, but not lead to high operating costs and make the enterprise embarrassed heavy burden.

5. Food safety

With the continuous improvement of people’s attention to food safety, the food safety of packaging materials is highly valued, and the update speed of food hygiene standards and regulations is getting faster and faster.Since other authors have described it in detail, it will not be repeated here.
