Stamping Parts are common metal parts and are widely used in various industries such as automobiles,electronics,and home appliances.They are manufactured through stamping,a process in which sheet metal is processed through a stamping die to deform the metal sheet into the desired shape.The following is a detailed introduction to the manufacturing process and working principles of stamping parts.
Stamping parts manufacturing process
1.Material preparation:
The first step in stamping manufacturing is to prepare the sheet metal.Commonly used materials include steel,aluminum,copper and other metal sheets,with thicknesses usually ranging from 0.1 mm to 6 mm.
2.Mold design:
According to the required shape and size of stamping parts,the corresponding stamping mold is designed.Stamping molds usually include an upper mold and a lower mold.The space between the upper mold and the lower mold is the stamping gap.The size of the stamping gap determines the size and shape of the final stamped part.
3.Blanking:
The metal sheet is placed on the workbench of the stamping machine,and the metal sheet is cut through the punching die to obtain a workpiece similar in shape to the stamping part.
4.Forming:
The punched workpiece is placed in the stamping die.Through the up and down movement of the stamping machine,the upper die and the lower die exert pressure on the workpiece,causing the workpiece to deform into the desired shape under the action of the die.
5.Plastic surgery:
After forming,some stampings may require further shaping to meet specific size and surface requirements.This includes operations such as bending and stretching.
6.Surface treatment:
Finally,stamping parts may require surface treatment,such as galvanizing,spraying,etc.,to improve their corrosion resistance and aesthetics.
Working principle of stamping parts
The working principle of stamping parts manufacturing is mainly based on the plastic deformation characteristics of metal sheets.During the stamping process,the metal sheet is plastically deformed by the pressure exerted by the stamping die,thereby turning into a workpiece of the desired shape.
Plastic deformation:During the stamping process,the metal sheet will plastically deform without breaking.This is mainly because when metal is stressed,molecules will slip between each other,allowing the metal sheet to deform into the desired shape.
Mold Design:The design of the stamping mold determines the shape and size of the final stamped part.By designing appropriate molds,stamping parts of various complex shapes can be manufactured.
Stamping gap:The size of the stamping gap will affect the size and shape of the final stamped part.A punching gap that is too small may result in a workpiece that is undersized,while a punching gap that is too large may result in an inaccurate workpiece size.
Material selection:The materials selected for stamping parts manufacturing will also affect the performance and forming difficulty of the final product.Usually,choosing materials with good plasticity and toughness can make stamping easier.
Process control:The stamping process requires strict process control,including the control of parameters such as stamping force,stamping speed,mold temperature,etc.,to ensure the quality and dimensional accuracy of the final product.
Through the above description of the manufacturing process and working principles,the manufacturing process of stamping parts and its application in various industries can be better understood.
