[0004] Although the existing high-toughness wear-resistant casting and forging rack is simple in structure and easy to use, it has a single function. The existing high-toughness wear-resistant cast and forged rack has low impact toughness and low overall wear resistance during the working process, which has certain adverse effects. It cannot play the role of cushioning when it is in contact with the rack, which has certain inconvenience. The existing high-toughness wear-resistant cast and forged rack cannot withstand the lateral strength of the rack surface during use, which has certain inconvenience. For this reason, We propose a high-toughness wear-resistant cast forged rack

The invention discloses a high-toughness wear-resistant casting and forging rack, which includes a rack body, a tooth surface is provided on one side of the outer surface of the rack body, and a reinforcement composite structure is provided on the outer surface of the upper end of the tooth surface. The present invention can reduce the pressure caused by the gears on the rack body through the occlusal buffer structure, slow down the stress strength of the rack body, increase the service life of the rack body, and be beneficial to people's use. , Structural changes to the rack body can effectively increase the overall wear resistance and impact toughness of the rack body, reduce the overall weight of the rack body, and greatly reduce the labor intensity of workers during handling and installation, which is beneficial to People's use, by strengthening the combined structure and strengthening the combined characteristics of the stick, effectively enhances the horizontal and vertical strength of the rack body, increases the stress strength of the rack body, and increases the service life of the rack body. It is beneficial for people to use.
Description
technical field [0001] The invention relates to the field of scraper conveyors, in particular to a high-toughness wear-resistant casting and forging rack. Background technique [0002] A high-toughness wear-resistant cast and forged rack is a cast and forged rack with high toughness and good wear resistance. It is easy to use and has been widely used. The functional requirements are also getting higher and higher. [0003] In the process of use, a high-toughness wear-resistant cast and forged rack can complete the following forms of operations: it can ensure the contact area and stress strength between the walking shoe of the coal mining machine and the rack. [0004] Although the existing high-toughness wear-resistant casting and forging rack is simple in structure and easy to use, it has a single function. The existing high-toughness wear-resistant cast and forged rack has low impact toughness and low overall wear resistance during the working process, which has certain ...
