Grinding device and grinding method for pig iron casting

Abstract

The invention discloses a grinding device for pig iron castings and a grinding method thereof, comprising a mounting box, grinding equipment and dust-absorbing equipment. The interior of the mounting box is fixedly installed with grinding equipment and dust-absorbing equipment, and the dust-absorbing equipment is located below the grinding equipment. Two sets of clamping arms realize the clamping and fixing of pig iron castings, realize the simultaneous grinding of multiple pig iron castings, and improve the grinding efficiency. The rotation speed and rotation direction of the motor are controlled by an external electronic controller to realize the position of the pig iron castings in the grinding direction. When moving, the rotation direction of the micro motor inside the grinding roller is opposite to the rotation direction of the motor, which increases the friction between the bottom of the pig iron casting and the grinding roller, and greatly increases the grinding degree. , reduce the work burden of the staff, and is more practical. The setting of the vacuum cleaner can realize the rough classification of metal scraps of various sizes, which is convenient for the recycling of scraps, and the economy is better.

Description

Technical field [0001] The present invention relates to the field of metal grinding techniques, and is specifically a grinding device of a cast iron casting and a grinding method thereof. Background technique [0002] As a common metal, the cast iron castings, it is necessary to polish and polishing during processing, and the metal performs polishing and grinding, which generally uses a professional polishing and grinding instrument equipment. The existing grinding equipment is more mechanical grinding equipment, using the grinding roller and the metal. Force, realize the grinding of the metal surface, but the existing grinding device is more single roller assembly, and only one set of metal parts can be placed at a time, the production efficiency is low, and the rotational speed of the grinding roller is fixed, that is, the friction between the grinding roller and the metal. Be sure, to re-install the feed assembly to realize the metallic feed, the equipment is complex, increase...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a grinding device for pig iron castings and a grinding method thereof. The clamping and fixing of pig iron castings can be realized through clamping arms. During actual use, multiple sets of clamping arms can be selected to be installed, and multiple pig iron castings can be realized. The synchronous grinding improves the grinding efficiency; the rotation direction of the micro motor inside the grinding roller is controlled by an external electronic controller to be opposite to the rotation direction of the motor, so that the relative moving speed between the pig iron casting and the grinding roller increases, and the bottom of the pig iron casting is in contact with the grinding roller. The friction force of the roller is increased, the grinding surface is smoother, and the grinding degree is also greatly increased. The surface of the pig iron casting can be ground more quickly, the grinding efficiency and grinding accuracy can be improved, the number of repeated grinding can be reduced, and the workload of the staff can be reduced. Strong; rough classification of metal scraps of various sizes can be achieved through the setting of dust collection equipment, which is convenient for the recycling of scraps and better in economy, to solve the problem that most of the grinding equipment proposed in the above background technology is a single-roller assembly, and only one group can be polished at a time For metal parts, the production efficiency is low, and the speed of the grinding roller is constant, that is, the friction between the grinding roller and the metal is constant. It is necessary to reinstall the feeding assembly to realize the feeding of the metal. The equipment installation is complicated and increases the workload of the staff. The practicability is not strong, the scraps after grinding are splashed, the recycling of metal scraps cannot be realized, and the economy is not good
