What Are The Methods Of Tungsten Steel Parts Factory Explaining The Flow Blocking Speed Of The Mold?

1. Introduction of Tungsten Steel Parts Factory

The obstruction angle of the file is fixed at a certain angle at the entrance of the working belt of the stamping and drawing mold. The obstruction angle is called the obstruction angle. The obstruction angle is the most commonly used method of mold repair. The obstruction angle is generally controlled between 3 to 12 degrees. In between, when the obstruction angle exceeds 15 degrees, it no longer works.

Work with repair welding. At the exit of the mold work belt. Weld a section of work tape as needed, the purpose of which is to increase the length of this section of work tape. To increase the resistance to metal flow.

3. Surfacing

Surfacing welding a boss around the die hole that needs to be blocked on the end face of the mold, shaped like a wall, to increase the flow resistance of the metal.

4, Tingling

The pitting points are formed on the end face of the stamping and drawing die by reducing the flow of the metal. The dense pits with a depth of 0.5 to 1 mm and a diameter of 1 to 3 mm are added to increase the frictional resistance between the metal and the die end face. The blocking method of the splitting die is different from that of the flat die. It is mainly to change the metal distribution amount by adjusting the rows of the splitting holes, thereby changing the metal flow. When the inlet angle of the mold core is increased, the metal flow velocity decreases, and conversely, the metal flow velocity increases.
