Coiling machine winding drum with complementary double hydraulic jaws

Abstract

.The invention discloses a coiling machine winding drum with complementary double hydraulic jaws. The coiling machine winding drum comprises a pyramid shaft, two jaw sector plates, two sector plates and two sets of jaw mechanisms. The jaw sector plates are arranged on the inclined face of the pyramid shaft like other sector plates, and are connected with the pyramid shaft through T-shaped keys fixed to the pyramid shaft / The jaw sector plates can do radial motion relative to a main shaft along with other sector plates when the winding drum is shrunk, a groove is formed in the top of the arc surface of each jaw sector plate, the jaw mechanisms are embedded into the grooves, a reset spring is embedded into the position under the center of each groove, and hydraulic cylinders are symmetrically arranged on the two longitudinal sides of the reset springs. According to the coiling machine winding drum with the complementary double hydraulic jaws, one winding drum can simultaneously meet the winding requirement of a thin strip and a thick strip with a large strip thickness interval span, the synchronous expansion and shrinkage of the jaw sector plates and the sector plates can be realized, the influence on the shape of a coil due to the fact that the inner ring of the steel coil is scratched by the winding drum or brought out during coil unloading can be avoided, and the clamping force is much larger than that of mechanical clamping in the prior art.

Description

Technical field [0001] The present invention relates to the technical findings of the rolling crump inverse device, and Background technique [0002] The looper is an important equipment on the strip continuous production line, which is mainly composed of a coiled machine reel and a gearbox. The cold rolled coil can determine whether the belt clamp or jaw device is configured according to the thickness of the belt thick, and the jaw device mainly has two types of mechanical jaws and hydraulic jaws for introducing steel and clamping the head, and then with the mill. Or other process equipment establishes tension and takes the strip normally under the action of the reel rotation. For the normal production line, the use requirement can be met using a jaw. However, a hot rolling (finishing) or annealed pickup unit for the strip thickness section is relatively large, and a jaw can no longer meet the production needs, and it is often solved by replacing the jaw bar or replacing the jaw...

AI Technical Summary

Problems solved by technology

However, for hot-rolled leveling (finishing) or annealing and pickling units with relatively large strip thickness intervals, one jaw can no longer meet the production needs, and often can only be solved by replacing the jaw strip or replacing the jaw device. question
