Abstract
The utility model relates to a mine scraper drawing template treadle bar, which is molded a plurality of times of quench-impact forging, and the treadle bar and three bolts are forged and molded integrally. The scraper drawing template treadle bar has high stress degree and tensile strength, large amount of over coal and low cost. The service life of the treadle bar can be prolonged to achieve the service life being the same as a chain and a keep plate, and the production efficiency in production is greatly improved.
Description
[technical field]
The utility model relates to the mine machinery field, relates to a kind of mine scraper plate machine scraper accessory or rather.
[background technology]
Along with high-speed development of science and technology, people improved for former more applied machineries, and the scraper plate machine press strip of use in mines does not change.The scraper plate machine press strip of existing import is a smart casting back die-forging forming.Though the accessory material is better, bolt is to be connected with base by press strip, and two ends connect with nut, so stressed not enough with tensile strength.When the import accessory using coal amount 3,000,000 ton hours, a large amount of fractures will appear, cause the disconnected scraper chain phenomenon of card and influence production, cause very big loss.
[utility model content]
The purpose of this utility model is the above-mentioned defective that overcomes prior art, and a kind of later-model mine scraper plate machine scraper press strip is provided.
Above-mentioned purpose of the present utility model realizes by following technical solution: with the repeatedly broken fiery die-forging forming of scraper plate machine scraper press strip, press strip and the forging and pressing of bolt one, just can improve the stressed degree and the tensile strength of scraper plate machine scraper press strip, cross the coal amount considerably beyond existing import scraper plate machine scraper press strip, and reach and scraper plate and same life-span of chain, and price has only 40% of import accessory, has improved productivity effect greatly.
[description of drawings]
Fig. 1 is a scraper plate machine scraper press strip lateral plan; Fig. 2 is its upward view.Wherein 1 is scraper plate machine scraper press strip, and 2 is the bolt on the scraper plate machine scraper press strip.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is specifically described.
With reference to figure 1 and Fig. 2, the utility model comprises scraper plate scraper plate press strip 1 and three bolts 2.
The utility model scraper plate machine scraper press strip is through the repeated hardening die-forging forming.Scraper plate machine scraper press strip 1 and described three bolts 2 are carried out the one forging forming.
The utility model name is called JOY3*700,855,1000 types, 48 chain converyer scraper plate machine scraper press strips, and piece number is: 100081192.
The foregoing description is only just for clearer explanation the utility model.Can not carry out any restriction to the utility model protection domain according to the foregoing description.Protection domain of the present utility model is as the criterion with the scope of claims.Persons skilled in the art can be carried out suitable adjustment and distortion to the utility model under the prerequisite of the utility model essence spirit, to adapt to specific needs.
Claims (2)
1. a mine comprises press strip and bolt with scraper plate machine scraper press strip, it is characterized in that scraper plate machine scraper press strip and bolt are to link together by the one forging and pressing.
2. mine according to claim 1 is characterized in that with scraper plate machine scraper press strip described bolt is three.
