Trimming circle shear for galvanized steel sheet

Abstract

The invention discloses a galvanized steel sheet trimming circle shear and belongs to the technical field of circle shears, the galvanized steel sheet trimming circle shear comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with the lower surface of a circle shear body, the left side and the right side of the inner wall of the circle shear body are each provided with an upper cutter head and a lower cutter head, and the upper surface of the bottom plate is fixedly connected with the lower surfaces of two baffles; the opposite faces of the two baffles are each provided with two transmission rollers. According to the galvanized steel sheet trimming circle shear, by arranging the material box, the rotating disc, the storage box, the upper cutter disc, the spring, the clamping rod, the clamping groove, the fixing plate, the connecting base, an oil leakage hole, a discharging pipe and a protective cover, the clamping groove is effectively clamped into the corresponding clamping groove, the fixing plate is effectively limited, and compared with a traditional mode that the cutter disc is cleaned or lubricated regularly, the cutting efficiency is improved; according to the scheme, the upper cutter head is effectively lubricated in time, the oil dripping amount can be adjusted according to the machining state of the circle shear, the machining precision is improved while the service life of the circle shear is guaranteed, and efficient and stable work of the circle shear is facilitated.

Description

technical field [0001] The invention belongs to the technical field of disc shears, in particular to a disc shear for edge trimming of galvanized steel sheets. Background technique [0002] Trimming disc shears are one of the core equipment on the metal strip finishing line (recoiling, slitting, tension leveling, pickling and other units), which are used to cut off the unqualified parts on both sides of the strip to ensure The width of the entire strip is consistent, which improves the accuracy of the strip width. The disc shears are only used for strip trimming in the transverse cutting unit, and longitudinal continuous shearing of narrow and wide strips can be carried out in the longitudinal shearing unit. It can be used as the longitudinal shearing of raw materials for cold-rolled strip steel, and it is also the main equipment of the cold-rolled strip steel longitudinal shearing and recoiling production line. The disc shearing machine usually uses a rotating disc blade to...

AI Technical Summary

Problems solved by technology

[0007] In order to overcome the above-mentioned defects of the prior art, the present invention provides a galvanized steel sheet trimming disc shear, which solves the problem that the opening degree tends to drift with the continuous shearing of the steel plate, causing the width of the steel strip after trimming to be different from the design. The error of the fixed width is relatively large, and in the case of steel belt deviation, it is easy to appear trimming burrs and edge wire defects. The personnel will regularly clean or lubricate the cutter head. The traditional lubrication method cannot realize timely cleaning of the cutter head. Lubrication treatment, the problem that the amount of dripping oil cannot be adjusted according to the processing state of the disc shears
