AI Technical Summary

Problems solved by technology

For example, the structural strength of the composite scraper itself is relatively low, and it needs to be often operated in harsh installation environments and complex extreme load conditions. After a period of use, its tensile strength, wear resistance, flame retardancy, and antistatic properties It will be further discounted, and often accompanied by poor conveying operation, severe local wear, and in severe cases, it will even cause the chain to break, resulting in a seriously lower than expected service life.

Abstract

The online compression molding die comprises an upper die body and a lower die body, the upper die body comprises a main cavity and end cavities communicated with the left end and the right end of the main cavity, the lower die body comprises a main groove and end grooves located in the left end and the right end of the main groove, and vertical joint parts are arranged between the main groove and the end grooves. The upper die is provided with a main groove, the lower die is provided with a main cavity, the front side and the rear side of the main groove are provided with groove protection frames protruding upwards, the main cavity comprises first stepped cavities matched with the groove protection frames, and after the upper die and the lower die are connected in a locked mode, the first stepped cavities cover the groove protection frames to form a forming cavity. According to the online compression molding mold and the molding process for the composite scraper, after compression molding of the composite scraper, the development requirement for light weight of coal machine equipment can be efficiently met, the use effect of the composite scraper after long-time use can be guaranteed, and the service life of the composite scraper is further prolonged.

Description

technical field [0001] The invention relates to the technical field of composite scraper processing and molding, in particular to an online molding mold and molding process for a composite scraper. Background technique [0002] Scraper conveying equipment is a continuous transportation machine that fixes the scraper on the chain as a traction member and transports materials in the middle tank. It has the advantages of large transportation capacity, wide adaptability to the environment, and simple maintenance. It is widely used in fully mechanized mining work in coal mines. in the face. In the scraper conveying equipment, the scraper and the pressure plate, bolts, nuts and chains form the scraper chain, and the scraper chain is the direct execution part that drives the movement of the transported materials. [0003] At present, in the coal machine transportation equipment, the scraper is an integral forged structure of low alloy steel. The manufacturing process is: die forgi...
