Polishing machine capable of conveniently polishing powder metallurgy mold cavity

Abstract

The invention discloses a polishing machine capable of conveniently polishing a powder metallurgy mold cavity. The polishing machine includes a machine body and a first T-shaped slide bar, the first T-shaped slide bar penetrates through an inner wall of the machine body, the first T-shaped slide bar is slidingly connected to the machine body, the periphery of the first T-shaped slide bar is provided with a fixing mechanism which can fix the first T-shaped slide bar on the left and right sides of a mold, can achieve front and back rotation and adjustment by a certain angle and enables the machine body to be in the middle portion of the mold all the time, and the front and back faces of the machine body are provided with clamping mechanisms for stabilizing the machine body. By means of the polishing machine, the cavity of the mold in use can be polished at any time, the mechanical clamp manner reduces the polishing errors generated by manual operation, and the grinding and polishing effects are effectively improved; and through the elastic effect, a polishing head can always be attached to the inner wall of the cavity, and the grinding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mold polishing, in particular to a polishing machine which is convenient for grinding the cavity of a powder metallurgy mold. Background technique [0002] With the vigorous development of powder metallurgy technology, more and more manufacturing industries adopt this technology to make products. It can not only directly produce products with complex shapes, but also greatly reduce the production time of products and save a lot of cost. However, During the use of powder metallurgy molds, the cavity will be continuously worn, and the cavity will become rough after a long time, which will lead to problems such as unsmooth mold release, mold sticking and product deformation. Permanent maintenance and grinding of the cavity to ensure the smoothness of the cavity, and the general grinding method is to disassemble the mold, then disassemble the mold parts, and finally manually squeeze the abrasive paste into th...

[0002] With the vigorous development of powder metallurgy technology, more and more manufacturing industries adopt this technology to make products. It can not only directly produce products with complex shapes, but also greatly reduce the production time of products and save a lot of cost. However, During the use of powder metallurgy molds, the cavity will be continuously worn, and the cavity will become rough after a long time, which will lead to problems such as unsmooth mold release, mold sticking and product deformation. Permanent maintenance and grinding of the cavity to ensure the smoothness of the cavity, and the general grinding method is to disassemble the mold, then disassemble the mold parts, and finally manually squeeze the abrasive paste into the cavity, and manually grind it with a grinder , this method is time-consuming and labor-intensive, and the accuracy is not high, and it is easy to cause problems of excessive grinding or cavity damage
