Dongguan hardware stamping parts manufacturer, basic stamping process + silk-like stamping precision

Dongguan hardware stamping parts manufacturers have said that the main basic processes of stamping are blanking, punching, bending and deep drawing. Xiaoshuo sorted out some relevant information, and let’s take a look at it together: (1) Blanking and punching Blanking and punching are processes that separate the blanks: The process of blanking and punching is exactly the same, but the purpose is different. . When blanking, the separated part is the finished product, and the remaining periphery is the waste; the punching is to obtain the hole, the punched sheet is the finished product, and the separated part is the waste. Blanking and punching are collectively referred to as blanking. Both the punch and the die of the blanking die have sharp edges, and there is a gap between the punch and the die that is equivalent to 5%-10% of the plate thickness to ensure a neat cut and less burrs. (2) Bending: Bending is to make the workpiece obtain various different shapes of bend angles. The working part of the bending die that makes the workpiece bend should have an appropriate fillet radius r to avoid cracking when the workpiece is bent. (3) Deep drawing: Deep drawing is the process of making flat blanks into cup-shaped or box-shaped parts. The edge of the punch and die of the drawing die should be rounded to avoid the workpiece from being cracked. There should be a gap slightly larger than the thickness of the sheet between the punch and the die in order to reduce friction. In order to prevent wrinkles, the edge of the blank needs to be pressed tightly with a pressing plate (binder ring). The actual deep drawing process of the product will produce the defect of cracking. Sheet stamping is a processing method that uses a die to separate or deform the sheet. Hardware, 15 years of ingenuity focused on metal stamping parts processing, hundreds of processing and production equipment, 20,000+ sets of customized stamping die production experience, monthly processing volume of 100+ sets of molds, daily production capacity of 3 million punches, with silk-like stamping precision, stamping The accuracy can reach 0.01mm, and 16 quality inspections are strictly controlled. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
