Problems solved by technology

These two production processes have high energy consumption, large waste of materials, and high cost. Moreover, in the subsequent heat treatment process, due to factors such as relatively complicated processes and strong correlation between processes, the product quality is unstable, and some parts appear cracks or even break. This phenomenon not only increases the manufacturing cost, but also affects the high yield and high efficiency of mining

Embodiment Construction

[0021] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the accompanying drawings that need to be used in the embodiments. Obviously, the accompanying drawings in the following description are some embodiments of the present invention. Ordinary technicians can also obtain other drawings based on these drawings on the premise of not paying creative work.

[0022] see Figure 1 to Figure 6 , the embodiment of the present invention provides a pressure plate for scraper conveyor, including a core bone 11, a wear-resistant layer 13 wrapped outside the core bone 11 for forming the main body of the pressure plate, between the core bone 11 and the wear-resistant layer 13 A bonding layer 12 is provided to fix and connect the core bone 11 and the wear-resistant layer 13 through the bonding layer 12. The core bone 11 is a strip-shaped structure, and the long strip-shaped core bone 11 is arranged ...

Abstract

The invention discloses a pressing plate for a scraper conveyor. The pressing plate comprises an arbor, and a wear resisting layer wrapped on the outer surface of the arbor for forming a pressing plate body; a bonding layer is arranged between the arbor and the wear resisting layer; positioning through holes are spaced in the arbor; a transverse gap is formed in the wear resisting layer above the arbor; and the wear resisting layer parts on two sides of the transverse gap are upwards projected to form a limiting table. The arbor serves as a support skeleton of the pressing plate, so that the strength and the toughness of the pressing plate satisfy the working demands; the wear resisting layer serves as a main body of the pressing plate, so that the pressing plate has needed strength for normal work, meanwhile, the wear resistance is greatly improved, the weight is obviously lowered compared with metal, the weight of the pressing plate is reduced, the total weight of a scraper chain is reduced, the idle loss of the scrape conveyor is reduced, the energy saving target is realized, meanwhile, the phenomenon of crack or even rupture caused by residual stress of heat treatment is prevented, and the overall life is largely prolonged.

Description

technical field [0001] The invention relates to the technical field of a pressing plate for a mine scraper conveyor, in particular to a pressing plate for a scraper conveyor and a production method thereof. Background technique [0002] The scraper conveyor is an important means of transportation for material transportation in mine development, and the pressing plate is one of its key components. The pressing plate, scraper, and chain cooperate to realize the function of transporting coal. When working normally, the chain passes through the scraper, and the pressure plate is arranged at the bottom of the scraper, and the chain and the scraper are relatively fixed by the scraper and the pressure plate. [0003] At present, the pressure plates for scraper conveyors used in domestic mines are all alloy steel or cast steel with high strength, high wear resistance and high toughness, which mainly rely on two production processes of casting and forging, and the pressure plates pro...
