Method for polishing diamond rectangle micropore mold die hole

Abstract

The invention discloses a method for polishing the die hole of a diamond rectangular microporous die; the basic proposal is as follows: the die is clamped in a clamp which is matched with the die, the position and direction of the die in the clamp can be adjusted, a polishing narrow band does up and down reciprocating motion to polish one group of opposite sides of the die hole of the die one by one, then the die turns at 90 degrees, the polishing narrow band polishes another group of opposite sides, in this way, the whole periphery in the die hole can be polished. The method for polishing the die hole of the diamond rectangular microporous die provided by the invention can polish a rectangular micropore, and can grind both the long edge and width edge of the rectangular die hole so as tofacilitate the maintenance of the shape of the die hole; the narrow band can not be distorted and broken in the polishing process, and the polishing efficiency is high.

Description

technical field [0001] The invention relates to a polishing method for a die hole of a mold, in particular to a polishing method for a die hole of a diamond rectangular microporous die. Background technique [0002] The semi-finished products of diamond wire drawing dies (referred to as: dies) are generally processed by laser. To meet the requirements, they must be polished and the aperture diameter is determined. Most of the finished products of diamond circular microporous wire drawing dies are ground and processed in the following two ways: [0003] 1. The steel needle coated with abrasive is inserted into the mold hole, and the polishing of the mold hole wall and the determination of the mold hole size are achieved through the left and right deflection of the steel needle and the rotational movement of the mold (such as figure 2 shown): [0004] 2. Apply abrasive on the polishing line passing through the mold hole, and achieve hole wall polishing and mold aperture size ...

AI Technical Summary

Problems solved by technology

[0006] (1) The position of the round hole mold in the fixture has no direction at all, that is, polishing in any direction in the fixture position can achieve the same effect, and the position of the rectangular hole mold in the fixture has directionality, otherwise the sides of the rectangle The amount of grinding is different, which affects its shape, so the fixture of the round hole mold is not suitable for the polishing of the rectangular hole mold;

[0007] (2) The processing method is not suitable. The polishing line section of the round hole mold is round, and the mold can be rotated, while the polishing line section of the rectangular hole mold is rectangular, and the mold cannot be rotated, otherwise the narrow polishing belt will be twisted and broken.
