Abstract
Description
Technical Field
[0001] This utility model relates to the field of finishing mill roll changing technology, specifically a strip finishing mill roll changing mechanism. Background Technology
[0002] Strip steel rolling is a core process in the field of metal pressure processing. By applying pressure to metal billets through a rolling mill, plastic deformation is caused, and strip steel with uniform thickness, smooth surface, and qualified mechanical properties is finally obtained. Strip steel rolling is the "choke point" of the steel industry. Its technical level directly determines a country's self-sufficiency in high-end steel and is also an important support for automobile lightweighting and the upgrading of new energy equipment.
[0003] In the process of hot rolling strip steel, in order to avoid wear and cracking of the roll surface, which would affect the surface quality of the strip steel product and thus cause strip steel quality defects, the work rolls need to be replaced after rolling a certain tonnage. The existing single roll replacement time is relatively long, which is not conducive to improving work efficiency.
[0004] In view of this, we propose a strip finishing rolling roll changing mechanism. Summary of the Invention
[0005] The purpose of this invention is to provide a strip steel finishing roll changing mechanism to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A strip steel finishing roll changing mechanism includes a roll, a left half-ring clamping plate on one side of the roll, and a connecting shaft on the other side of the roll. The connecting shaft is fixedly connected to the side wall of the left half-ring clamping plate, and a rotating sleeve is rotatably connected to the side wall of the connecting shaft. The side wall of the rotating sleeve is fixedly connected to the side wall of the right half-ring clamping plate. The side wall of the left half-ring clamping plate has multiple threaded grooves, and a fixing bolt is provided on one side of the right half-ring clamping plate. One end of the fixing bolt passes through the right half-ring clamping plate and is threadedly connected to the threaded groove. The other end of the fixing bolt is fixedly connected to a pressing block. A rotating disk is fixedly connected to the side wall of the pressing block, and U-shaped hooks are fixedly connected to the surfaces of the left half-ring clamping plate and the right half-ring clamping plate.
[0008] When it is necessary to replace the roll, the left and right half-ring clamps can be placed on the outside of the roll. Then, the fixing bolts and threaded grooves are aligned symmetrically. The rotating disk is then rotated to connect the fixing bolts with the threaded grooves. After tightening the fixing bolts, the pressing block will abut against the side wall of the right half-ring clamp, thereby connecting and fixing the left and right half-ring clamps. Then, the crane connecting belt is passed through the U-shaped hook to lift the roll for replacement. The replacement method is simple, convenient, and helps to improve work efficiency.
[0009] Preferably, a rotating handle is rotatably connected to the side wall of the rotating disk;
[0010] By setting a rotating handle, when the rotating disk needs to be rotated, the rotating disk can be rotated by pushing the rotating handle, which makes it easy to tighten the fixing bolts.
[0011] Preferably, the side wall of the rotary handle is fitted with a rubber sleeve;
[0012] By incorporating a rubber sleeve, the comfort of gripping the rotating handle is improved.
[0013] Preferably, the side wall of the pressing block is fixedly connected with an anti-slip pad;
[0014] By setting an anti-slip pad, when the pressing block abuts against the side wall of the right half-ring plate, the anti-slip pad will be located at the connection between the pressing block and the right half-ring plate, reducing the possibility of the pressing block becoming loose.
[0015] Preferably, both sides of the left and right half-ring clamps are fixedly connected with multiple reinforcing hooks;
[0016] By setting up reinforcing hooks and tightening the fixing bolts, straps can be used to pass through the reinforcing hooks to fix the left and right half-ring plates, improving the stability of the connection between the left and right half-ring plates.
[0017] Preferably, the inner walls of the left half-ring plate and the right half-ring plate are fixedly connected with anti-slip sleeves;
[0018] By setting up anti-slip sleeves, when the left and right half-ring clamping plates wrap around the roll, the anti-slip sleeves will abut against the side wall of the roll, fixing the roll between the left and right half-ring clamping plates, thus preventing the roll from rotating randomly and affecting the handling.
[0019] Preferably, the sidewall of the anti-slip sleeve has multiple strip grooves;
[0020] By setting the grooves, the roughness of the anti-slip sleeve sidewalls is increased, friction is increased, and the fixing effect is improved.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] This strip steel finishing mill roll changing mechanism allows for roll replacement by placing the left and right half-ring clamps on the outside of the roll. Then, the fixing bolts are aligned symmetrically with the threaded groove. The rotating disc is then rotated to connect the fixing bolts to the threaded groove. After tightening the fixing bolts, the pressing block abuts against the side wall of the right half-ring clamp, thus connecting and fixing the left and right half-ring clamps. Finally, the crane connecting belt is passed through the U-shaped hook to lift the roll for replacement. The replacement method is simple, convenient, and improves work efficiency.
