What is the allowance of the metal continuous die?

The machining allowance is related to your pre-machining accuracy. If the front machining accuracy is high, you can leave less allowance, otherwise leave more. Leave too little, and you may not be able to hit some places when you are listless. Leave some silk for the front, it may be a little too little. Leave at least 0.2 ~ 0.3 mm.

Do it.

Machining allowance is the difference between the machining size of the parts to be machined on the surface of the blank and the blank size. It depends on what mold you make. If the error of the blank mold is large, you can put more allowance, or if the volume is large and the casting shrinkage is large, it will shrink. If rough machining is done, you can put 1mm on one side, and if there are products that need surface inspection, you can put 5-8mm on the other side. In this way, even the pores and impurities in the casting process can be removed.

Extended data

In industrial production, metal molds are parts or products that use various presses and special tools installed on the presses to make metal materials into required shapes. This special tool is collectively called metal mold.

All kinds of tools and products used in our daily production and life range from the base and fuselage shell of the machine tool to an embryonic head screw and button.

As well as the shells of various household appliances, are closely related to mold. The shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determine the quality of these products. Due to the different materials, appearances, specifications and uses of various products, molds can be divided into non-plastic molds such as casting molds, forging molds, die-casting molds, stamping molds and plastic molds.

In the process of continuous die stamping, the material belt always moves in one direction; Progressive die means that the material belt in the die moves in two or more directions after cutting. Call the automatic continuous die when the material belt enters the die; In the stamping production chain, the manipulator or other automation facilities used for stamping dies with different processes are used to move dies or parts to complete the stamping of workpieces. Rated dies are called multi-station dies.
