Rotary multiple-station forming machine for grinding wheel

Abstract

The invention discloses a rotary multiple-station forming machine for a grinding wheel, which comprises a center pillar, a side pillar and a head component of a main compressor, wherein the center pillar and the side pillar are mounted on a frame; the head component of the main compressor is arranged at the tops of the center pillar and the side pillar; a working turntable is sleeved on the lower part of the center pillar in a rolling manner; a plurality of mould hole seats and grinding wheel moulds in the mould hole seats are uniformly arranged on the working turntable according to stations; a lower workbench is arranged below the working turntable and on the frame between the center pillar and the side pillar; and an unblocking and billet moving device, a material stirring device and a scraping device are arranged around the working turntable in sequence. The rotary multiple-station forming machine for the grinding wheel has the advantages of compact structure, low manufacturing cost, high automation degree, and relatively lower requirements on forming materials and production environments, thereby greatly improving product quality and efficiency and reducing the labor intensity. Due to the adoption of multiple-station operation in which the unblocking and billet moving device, the material stirring device and the scraping device are arranged around the working turntable in sequence, and the grinding wheel forming process is carried out on a plurality of operational stations, unit action is simplified to the most extent.

Description

technical field [0001] The invention relates to ceramic grinding wheel and resin bond grinding wheel molding equipment, in particular to a grinding wheel rotary multi-station molding machine. Background technique [0002] At present, medium-sized grinding wheels (ceramic grinding wheels with an outer diameter of 300-500 mm and a thickness of 10-100 mm, and resin-bonded grinding wheels) are mostly formed by manual scraping machines. Its composition is: one hydraulic press equipped with one or two auxiliary machines, the auxiliary machines include a spreader turntable that drives the mold to rotate, a hydraulic demoulding device, a manual or mechanically propelled mold car, etc. Its mode of operation is: manually feed materials into the mold, manually use a stirring fork to stir the material, manually use a scraper to scrape the molding material, manually or a spreader is placed on the upper cover of the mold, and then the mold car is manually or mechanically propelled.

AI Technical Summary

Problems solved by technology

The whole operation process is cumbersome, time-consuming, inefficient, and the labor intensity of the operator is high; and due to the influence of human factors, the density uniformity of the formed grinding wheel blank is poor, and the static unbalance value is high, which also has an adverse effect on the performance of the grinding wheel

At present, there are generally two types of foreign equipment imported in China: 1. The hydraulic machine is equipped with two sets of automatic auxiliary machines: its feeding, stirring, scraping, demoulding, and body turning are automatically completed by mechanical devices, but most of them The operations are all concentrated on one station, resulting in low efficiency, complex equipment configuration, and very expensive prices

2. Swing arm type three-station molding machine: feeding and scraping, pressing and molding, demolding and blanking are divided into three stations to complete; although this equipment improves the molding efficiency, its feeding method is constant volume feeding, which is not conducive to The gas in the molding material is discharged, and there is a servo adjustment device for the depth of the mold cavity. The mechanism is relatively complicated, and the looseness and uniformity of the molding material are extremely high. At the same time, the total weight and thickness of the grinding wheel have large deviations, and the waste of molding material is relatively large. High and very expensive
