Sand wheel automatic production line

Abstract

The invention relates to a sand wheel automatic production line, comprising a sand wheel molding die, and a lower mesh placing system, a charging system, a feeding system, a scraping system, an upper mesh placing system, a mesh pressing system, a core ring placing system and a block press which are arranged on a production rail in sequence; and the sand wheel molding die is arranged and conveyed at the production rail and sequentially finishes lower mesh placing, charging and feeding, flat scraping, upper mesh placing, mesh pressing and flattening, core ring placing and die press molding. The automatic degree is high, charging is convenient, feeding is stable and uniform, meshes are flatly placed, raw materials in the die are uniform and the die press molding quality of a sand wheel is favorably improved.

Description

Technical field [0001] The invention relates to a grinding wheel production equipment, in particular to an automatic grinding wheel production line. Background technique [0002] As a main grinding tool, the grinding wheel is made by using a mixed raw material of abrasive and bonding agent through compaction, drying and roasting. In the traditional production process, it is made by mixing abrasives and binders, and then pressing, drying and roasting. The materials are added to the mold blank and sent to the press to be completed manually. There are the following shortcomings: the amount of material added in the grinding wheel mold Manual addition, the molding quality of a single piece of grinding wheel cannot be controlled, and the product quality is stable and the consistency is poor; the density and flatness of the raw material in the grinding wheel mold blank determine the quality of the molding of the grinding wheel. Time-consuming and laborious, the density and flatness of ...

AI Technical Summary

Problems solved by technology

In the traditional production process, it is made by mixing abrasives and binders, then compacting, drying and roasting. The material is added to the mold blank and sent to the press by hand. There are the following disadvantages: the amount of material in the grinding wheel mold blank depends on The quality of the single-piece grinding wheel cannot be controlled by manual feeding, and the product quality is stable and poor in consistency; the density and flatness of the raw materials in the grinding wheel mold blank determine the molding quality of the grinding wheel compact. Time-consuming and labor-intensive, the density and flatness of the raw materials in the mold blank are not easy to control, the product quality after compacting and firing is uneven, the consistency is low, and the yield is low; the manual placement of the mesh does not have accurate positioning, and the subsequent manual addition and leveling of raw materials When the material is impacted and moved evenly, it is easy to cause damage, offset or uneven placement of the mesh, which will reduce the overall strengthening effect of the grinding wheel, or even have a negative effect, and the quality of the grinding wheel cannot be guaranteed; manual placement of the core ring is cumbersome and labor Low efficiency and high labor intensity; manual placement of the core ring without accurate positioning, the impact and leveling of the raw material will easily cause the core ring to shift or be placed unevenly, which will affect the quality of the grinding wheel forming; After being pressed into a billet by a molding machine, it is dried and roasted

In the environment with high working temperature in summer, when the molding head presses the grinding wheel blank, it is easy to stick out the grinding wheel blank from the grinding wheel forming mold, which affects the production operation
