China Factory Cheap Price Scraper Conveyor Parts Sprocket

Product Details

With the increasing demand of coal quantity in fully mechanized coal face, the sprocket assembly of plate scraper at the beginning of design has no way to adapt to the demand of coal mine. With the increasing load, the problem of short service life of sprocket assembly of plate scraper gradually appears. Henan Shuangzhi Machinery as a sprocket assembly manufacturer, in order to adapt to coal mining production, the sprocket assembly scraper for the material and process optimization upgrade!

selection of material for sprocket components of plate scraper

The design material of the sprocket assembly of the original plate scraper was 40Cr. The overall hardness after tempering was HB220-250, and the hardness of the gear teeth after tempering was HRC48-52. The sprocket assembly of the plate scraper had limited wear resistance, so it was difficult to bear a large load. After quenching, the hardness of the whole sprocket can reach HB250-280, and the hardness of the gear teeth can reach HRC50 and above, and the wear resistance can be greatly improved. In this way, the service cycle of the sprocket components of the board scraper can be greatly enhanced, and the maintenance and replacement frequency of the sprocket components of the board scraper can be greatly reduced, thus reducing the production cost.

Sprocket body forging and reprocessing of sprocket assembly of plate scraper

The sprocket body shape of the sprocket assembly of the original plate scraper is forged directly, the size error is large, the surface is relatively rough, which also reduces the wear resistance, making the wear faster. After the improvement, the sprocket body of the sprocket assembly of the plate scraper is firstly forged and shaped with a slightly larger size than the finished product. Then, the sprocket body is processed by various CNC machine tools to enhance the dimensional accuracy and surface roughness of the sprocket assembly.

3. German four-axis linkage machining center precision milling and scraping machine sprocket assembly chain

After the improvement of the sprocket assembly processing flow of the scraper, Henan Shuangzhi Machinery introduced the German four-axis linkage processing center to mill the chain socket, which makes the chain socket of the sprocket assembly of the scraper smooth and reduces the occurrence of chain chomping. The sprocket assembly of the scraper can be used in the underground complex environment!

Change constantly, can develop! Henan Shuangzhi Machinery has been constantly optimizing their own products, refined products, service customers! The improvement and optimization of the sprocket components processing of the scraper is also the embodiment of the continuous progress of Henan Shuangzhi Machinery, and more scraper accessories and other products are also in the continuous improvement and enriching, looking forward to your witness and cooperation!
