Stamping parts processing is power by means of conventional or special stamping equipment, dongguan hardware stamping sheet is directly in the mold deformation force and deformation, thereby gaining a certain shape, size and function of the production technology of product parts.
Sheet metal, stamping mould and equipment is processing of the three elements.
Cold stamping processing is a kind of metal deformation processing method.
So, called cold stamping or sheet metal stamping, stamping for short.
It is plastic metal processing (
Or pressure processing)
One of the main methods, also belongs to the material molding engineering technology.
Used by stamping mold known as the stamping die, die for short.
Die is the material (
Metal or nonmetal)
Batch processing into salt pieces of special tools required.
Is of vital importance to the die in stamping, did not conform to the requirements of punching die, stamping production batch is difficult;
Did not improve the elder die, improve predecessors of stamping process cannot achieve.
Metal stamping parts mainly is the metal or nonmetal sheet, with the aid of the pressure of the press, through the stamping die stamping forming.
1, metal stamping parts, mainly is the metal or nonmetal sheet, with the aid of the pressure of the press, through the stamping die stamping forming, it basically has the following features: 2, stamping parts is on the premise of material consumption is not big, created by the stamping, light weight, good stiffness, its parts and sheet metal after plastic deformation, metal internal organizational structure to improve, to improve strength of stamping parts.
3, the size of the stamping parts with high precision, with the module size uniform, good interchangeability.
Don't need to be further mechanical processing to meet the requirements of the general assembly and use.
4, stamping parts processing in stamping process, due to the surface of the material are not destroyed, therefore, have good surface quality, smooth and beautiful appearance, for the surface paint, electroplating, phosphating and other surface treatment provides a convenient conditions.
Stamping process and die, stamping equipment and materials to form the three elements of stamping processing, can only draw stamping them together.
1 stamping parts processing.
According to determine the deformation amount of compensation, including material, product structure 2.
According to the amount of compensation design finished or semi-finished die stamping out 3.
Processing semi-finished products to finished product 4.
Bad phenomena including crack, wrinkle, strain, uneven thickness, not forming such as tapping and thread processing: 1.
Internal thread first drill base hole diameter and depth (
Bottom hole size according to thread specification size, online search a lot)
External thread machining large diameter cylindrical to thread size (first
According to the thread specifications to determine the size, online search a lot)
Processing thread: internal thread with corresponding grade tap tapping;
Outside the thread with a thread cutter turning or die set pepper. serve. 3.
Bad phenomena including wire disorderly buckle, a different size, thread gauge repair divisions, the materials mainly selected according to the requirement of copper, aluminum, such as low carbon steel with low deformation resistance, good plasticity and ductility of metal or nonmetal as for repair specification according to the product requirements established, dongguan hardware stamping thread repair has national standard of the thread gauge, hole maintenance according to the national standard design special plug gauge or buyer mark dimension size plug gauge.
