Grinding head for mold repair

Abstract

The invention discloses a grinding head for mold repair. The grinding head comprises a shell, a worm, a worm gear, a thermal deformation piece, a high-frequency electromagnetic induction coil, a second gear tower, a first gear tower, a hand wheel, a motor, a clamping piece and a grinding head body, wherein the shell is a supporting body, the motor drives the grinding head body to rotate through the clamping piece, and finishing of the surface of a mold is realized; during manual feeding, feeding and retreating of the grinding head body can be realized by rotating the hand wheel, five gears are available for manual feeding, and manual feeding can be used for idle stroke movement of the grinding head body and rough machining of the surface of the mold to improve the repair efficiency; and during thermal stress feeding, a micro sliding block is pushed rightwards, the thermal deformation piece is heated through the high-frequency electromagnetic induction coil, micro feeding of the grinding head body is realized according to the principle of thermal expansion and cold contraction, and thermal stress feeding can be adopted during fine finishing of the surface of the mold to improve the machining quality of the surface of the mold.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a grinding head for mold repair. Background technique [0002] Molds play an extremely important role in modern industry, and the quality of molds directly determines the quality of products. my country's mold industry has developed rapidly in recent years and has become one of the top three mold producing countries in the world. However, there is still a big gap between my country's mold industry and foreign advanced mold production levels, mainly in the long manufacturing cycle, low manufacturing precision, and mold production. In terms of short life, the problem of short mold life is particularly prominent, which directly leads to the waste of resources and the increase of production costs. Therefore, repair and reuse the failed molds to prolong the use time of the molds, thereby recovering unnecessary losses in production , will greatly promote the development of industry ...
