Outer supporting device for coiling block of uncoiling machine and coiling machine

Abstract

The invention discloses an outer support device for an uncoiler and a coiler drum, which comprises a support, the top of the support is hinged with one end of a support arm, the support arm is hinged with one end of a connecting rod I, the other end of the connecting rod I is hinged with one end of a connecting rod II, and the other end of the connecting rod II is hinged with the bottom of the support. An oil cylinder support is fixedly connected to one side of the bottom of the support, the oil cylinder support is hinged to an expansion oil cylinder, and the tail end of a telescopic rod of the expansion oil cylinder is hinged to the second connecting rod. Through the mechanical structure design, the complexity of the outer support is reduced, the reliability of the outer support is reserved, the occupied area of equipment is reduced, the problem of mechanical interference between the outer support and the head of the winding drum is solved, and meanwhile the equipment manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of the field of steel rolling equipment, in particular, to an external support device for the reel of an uncoiler and a coiler. Background technique [0002] At present, the mainstream external support devices of cold-rolled reels in domestic steel mills are swing arm external supports, that is, the transition of the main device of the external support relative to the reel between the supported state and the unsupported state, just like opening and closing the door, it needs to be rotated 90°. This form of external support device has a reliable but complex structure, and occupies a large area. It requires sufficient movement space for the external support body device. When the external support device body is in contact with the reel head, mechanical interference and wear are likely to occur. For the problems in the related technologies, no effective solutions have been proposed so far. SUMMARY OF THE INVE...

AI Technical Summary

Problems solved by technology

This type of external support device has a reliable but complicated structure and occupies a large area. It needs to leave enough space for the main body of the external support device to move. When the main body of the external support device contacts the head of the reel, mechanical interference and wear are prone to occur.
