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.

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. Relative thickness of blank T/D

C. Drawing method: when there is a pressure ring, the drawing coefficient M can be smaller.

D. Die structure: the drawing coefficient is greatly affected by the size of the round corner of the concave punch of the drawing die and the clearance between the concave punch.

E. Friction and lubrication conditions: the contact surface between the die, pressure ring and the blank shall be smooth.But punch and blank contact surface to rough some good, not lubrication, in order to increase the friction, reduce the possibility of cracking.

Tinplate box is used as packaging gift box, which is more expensive than the paper box, but still loved by businesses.What makes broad businessman abandon cheap carton, plastic to wrap?Let us check what advantage tinplate box has in craft, printing, anticorrosive ability.

Tinplate tin can is commonly known as tin can or tin box, tinplate box made of tinplate material is tinplate (also known as tinplate is commonly known as galvanized tin plate, English abbreviation is SPTE).A tin can is an iron surface coated with tin.Tin ACTS as a protection against corrosion and rust.Tinplate combines the strength and formability of steel with the corrosion resistance, solderability and aesthetics of tin in a material, which has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility.

1. Tin cans can be used as packaging to show the high-end and high-end selling points of products.

It’s popular due to the good printing performance, the production of a variety of box types, the design and printing of exquisite patterns and engraving.

2. Tin can has good sealing property and can effectively prevent nutrient loss.

Good sealing, good confidentiality can avoid oxygen invasion, avoid rapid loss of protein, effectively reduce the breeding of toxic bacteria.

3. Tin can is opaque to avoid adverse reactions of food and beverage caused by light

Storage of fatty foods, if exposed to light, it can lead to deterioration of oxidation reactions, resulting in protein, amino acid changes and a large loss of vitamin C.

4.The reduction of tin in tin cans helps preserve nutrients better

Tin on the inner wall of tinplate ACTS with the oxygen remaining in the container during filling help to reduce the chance of oxidation of food ingredients.

5. Tin can has good mechanical properties and is not easy to break

High strength, good rigidity, not easy to break.It can be used for small sales packaging, but also the main container of large transport packaging
