Three-roll belt head forming device with pinch function

Abstract

The invention relates to a three-roller strip head forming device with a pinching function. The three-roller strip head forming device comprises a frame, an upper roller, an inlet lower roller, an outlet lower roller, an inlet guide plate, a middle transition guide plate, an outlet guide plate, a lower roller height adjusting mechanism and a transmission device, the upper roller is matched with the inlet lower roller to form a pinching roller set, the upper roller, the inlet lower roller and the outlet lower roller are matched to form a strip head forming roller set, the transmission device rotates forwards or backwards to drive strip steel to a crop shear device or to return to the strip head forming roller set for forming, and the lower roller height adjusting mechanism can adjust the heights of the inlet lower roller and the outlet lower roller, so that the forming requirement of the strip steel with different thicknesses is met. The three-roller strip head forming device has the advantages that the strip steel is conveyed and formed, the device can adapt to the strip steel with different thicknesses, the head of the strip steel obtains the needed bent shape, and a strip can smoothly penetrate the three-roller strip head forming device as the inlet guide plate, the middle guide plate and the outlet guide plate are designed.

Description

Technical field [0001] The invention relates to the technical field of cold rolling, in particular to a strip forming device with a head, and in particular to a three-roll head forming device with pinching function. Background technique [0002] At present, in the production process of a cold-rolled plate and strip unit, the strip head after the previous process often shows an irregular shape. It is usually pre-processed before entering the unit, which is generally the leading forming process after cutting, so that the leading can achieve smooth belt threading, improve the production efficiency of the unit, and increase the effective production time of the unit. [0003] In the prior art, the head warping treatment is generally a two-roll pinch roller plus a three-roll straightening machine. This structure and arrangement increase the length of the unit and increase the weight of the equipment. The upper roller and the two lower rollers are arranged symmetrically, and the relative...

Problems solved by technology

[0003] In the existing technology, the head warping treatment of the belt head is generally two-roller pinch roll plus three-roller leveler. This structure and arrangement increases the length of the unit and the weight of the equipment, and the three-roller leveler The upper roller and the two lower rollers are symmetrically arranged, and the relative height adjustment of the two lower roller surfaces cannot be realized
