Sheet metal processing is divided into production opening, metal stamping, bending, forming, welding, polishing, spraying, printing, assembly and other processes. Today, we will introduce the process knowledge of metal stamping this process in detail.
Metal stamping processing process is a kind of optical fiber laser cutting production and processing method of metal materials, its important for metal materials, according to metal stamping machine tools and other pressure equipment to force the material to cause deformation or separation, in order to get the actual requirements of the product parts, here collectively known as: metal stamping parts.
Die metal stamping process has a variety of situations, here I give you a summary of the most extensive metal stamping process.
1, The blanking
A general term for a metal stamping process in which materials are extracted. It includes: blanking, punching, punching, punching, cutting, cutting, pressing, cutting and so on.
2. Appearance design
It is mainly a metal stamping process that cuts out the excess parts outside the material to ensure that they meet the requirements of specifications and models.
3, Cut the tongue
A certain part of the material is cut into a slit, but not all of it is cut. It is common for the rectangle to cut only three sides and keep one side unchanged. The main role is to set the step distance.
4, Flaring
This process is not extensive, through metal stamping to expand the orificket, most tubular parts will end or a end to expand outward into a trumpet shaped process
5, Reducing
Shrinkage is the opposite of flaring. It is a metal stamping process in which the end or a certain point of the tubular part must be reduced inward
6, Punching
In order to better obtain the hollow part of the part, the corresponding hole size will be obtained by separating the material through the punch and the cutting edge in the middle of the complete material
7. High precision metal stamping
When the metal stamping part needs the section quality to be full bright zone, it can be called "fine blanking" (Note: ordinary blanking cutting surface is divided into four parts: collapse Angle zone, bright zone, fault zone and burr zone)
8, All bright blanking
Different from high precision metal stamping is full bright blanking as far as possible in one step blanking
9. Deep hole blanking
When the diameter of the product is less than the thickness of the material, it can be mastered as deep hole punching. The metal stamping difficulty is manifested as the insert needle is very easy to break
10. Hit the convex hull
A process in which a bulge is created on a flat sheet material to meet relative application requirements
11, Forming
Many friends grasp the molding into sheet metal parts sheet metal bending, it is not careful and serious. Because sheet metal parts sheet metal bending is a type of forming, forming refers to the general name of all fluid material processes
12. Sheet metal parts sheet metal bending
A basic process in which the plate material is brittle and fractured according to the convex and concave die inserts to obtain the relative Angle and shape
13. And embossing
This kind of structure is generally used in sheet metal bending forming inserts of sheet metal parts with inclination Angle. It is mainly based on making a convex pit of the material at the bending position of sheet metal parts to reduce the elasticity of the material and ensure the stability of the Angle
14. Pressed bar
A process in which a distinctive design pattern is pressed into the surface of the material according to the insert needle, which is widely used: embossed characters, small black dots, etc
15, Crimping
Molding production process is a process based on the product design to fold into a ring
16, Double holes
A process in which the thread of a metal stamping piece is warped to obtain a side of a certain height
17, Straightening
Mainly in view of the high flatness requirements of the product, when the metal stamping parts appear flatness error due to the stress field, it is necessary to use the aligning process to adjust
18, Integers
When the product is formed and the Angle and shape are not the basic specifications, it is necessary to fully consider adding a step to adjust the Angle to ensure the stability of the Angle. This type of process is called "integral type".
19, Tensile
Generally refers to the whole process of getting hollow parts from flat material according to the method called drawing process, which is mainly carried out according to convex and concave die
20. Keep stretching
Generally refers to a Lashen production process caused by multiple times of material in the same position according to a pair or four molds in a material belt
21. Become loose and deep
Continuous Lashen and deep Lashen belong to the looser Lashen series, which means that the wall thickness of the parts after Lashen will be less than the thickness of the material itself
22, Tensile
The basic concept is similar to convex hull, which is to bump the material. However, drawing generally refers to car parts, which belong to a more complex forming product series, and its drawing structure is relatively complex
23. Construction project model
A set of mold a metal stamping process only to carry out a metal stamping process of the mold collectively
24, Composite die
A set of mold a metal stamping process can be carried out two or more than two different metal stamping processes of the mold collectively
25, Metal stamping die shell
A set of mold by the material belt feeding, will be more than two kinds of process sequence, with the metal stamping process in turn into the final qualified product of the mold type general name
