Optimize the Welding Frame of Jaw Crusher

In order to alleviate the country's economic development pressure of environmental protection, reduce the production cost of crusher, satisfy mobile crushing screening to jaw crusher dimension requirement, through the efforts of the technical personnel, the traditional cast steel frame structural optimization to jaw crusher, design an improved welding frame of jaw crusher.

The crusher has the advantages of simpler structure, higher efficiency, shorter manufacturing cycle and lower production cost, appearance is more beautiful, the manufacture process more environmental protection, etc. The improved welding frame jaw crusher performance improvement, compared with cast steel frame jaw crusher, also has the following advantages:

(1) Frame there is no casting defects and welding stress, use more reliable. Frame adopts steel plate after welding, in manufacturing process, adopts special way for the entire machine frame is carried out to deal with the stress, avoids the casting defects, and solved the past due to restricted by equipment, technology cannot solve the problem of the welding stress, ensure the rack is in use process will not make the rack by casting defects and welding stress scrap.

(2) The moving jaw design was optimized by using a three-dimensional simulation, corrected the previous design is not reasonable, make it more simple and reasonable structure, stress condition is better. And their weight and to reduce the 0.24 t, implements the effective cost reduction.

(3) Adjust the installation seat wedge lock; Frame bearing bushing set assembly, and positioning in the joint flat key; Discharging mouth adjustment agencies cancelled a pull rod; Pulley, flywheel and eccentric shaft adopts expansion sleeve connection, both simplified structure, greatly facilitate the maintenance and installation, and the connection is more reliable, reduces the failure probability.

(4) As we all know, the steel plate surface quality is much better than steel. Plus with thick steel plate welded together frame external structure is simple, thus forming production crusher appearance quality is quite good. Due to the current market to the internal quality and appearance quality requirement of the crusher are more and more high, so the improved crusher favored by users.

Jaw crusher frame from casting to steel plate after welding, to a certain extent, reduced the production of castings; corresponding national economic construction of environmental pressure is reduced. At the same time for the crusher production enterprises themselves also improved its development prospects, so there is no doubt its social benefits.
