Strip tail blending machine

Abstract

The invention relates to the filed of metallurgical machinery, in particular to a strip tail blending machine, which comprises a rack, a lower steel roller construction member, an upper steel roller construction member and a driving element thereof, wherein the rack is fixed on a ground base and is fixedly fixed and connected with the lower steel roller construction member, the driving element is arranged on the top of the rack, the driving element is connected with the upper steel roller construction member and drives the upper steel roller construction member to lift, and the upper steel roller construction member and the lower steel roller construction member coordinate and blend a strip steel and strip tail. In the invention, a hydraulic cylinder drives a squeezing head of a pressure lever to push a moving steel roller to blend the strip tail, thereby ensuring the rolling and baling of the strip tail smoothly, and avoiding the damage to the recoiling machine, the steel coiling car and the like; and the hydraulic cylinder is equipped with a linear displacement sensor which feeds back the practical value of rolling reduction, controls the action of the hydraulic cylinder and restricts the rolling reduction through a limit pressure pad, so that excessive blending is avoided, and the device is applicable to strip blending of strip materials of various thickness, has simple operation, high controlling accuracy, long service life and is easy to maintain.

Description

technical field [0001] The invention relates to the field of metallurgical machinery, in particular to a tail bending machine suitable for the production of medium-thick strip steel, which bends the tail of the strip after slitting, so as to facilitate the smooth completion of winding and bundling of the thick strip during coiling. . Background technique [0002] During the production of medium-thick strip steel, it is necessary to bend the tail of the strip after slitting, so as to facilitate the smooth completion of winding and bundling of thick strip steel during coiling. For example, the hot-rolled annealing and pickling line of Zhangjiagang Pohang Stainless Steel Co., Ltd. has a thick product specification (δmax=16mm) and high yield strength. Therefore, when the exit coiler of the unit is coiling the tape tail, the tape tail is not easy to wind tightly, which in turn causes It is inconvenient to unload, transport and bundle steel coils at export, and it is easy to dama...
