Description

Galvanized steel sheet side cut circle shear

Technical Field

The invention belongs to the technical field of circle shears, and particularly relates to a galvanized steel sheet edge cutting circle shear.

Background

The trimming circle shear is one of core devices on a metal plate strip finishing line (recoiling, longitudinal shearing, pulling and straightening, pickling and the like), is used for shearing off unqualified parts on two sides of strip steel, ensures the width of the whole strip steel to be consistent, improves the precision of the width of the strip steel, is only used for trimming the strip steel in a transverse cutting unit, and can be used for longitudinally and continuously shearing narrow strip steel and wide strip steel in the longitudinal shearing unit. The shearing machine can be used for longitudinally shearing the raw material of the cold-rolled steel strip, and is also a main device of a longitudinal shearing and rewinding production line of the cold-rolled steel strip. When it is used to cut edge, it is usually equipped with a scrap chopper to cut the edge into small segments for easy recovery, and the disc shear can be divided into two types according to the purpose: disc shears for shearing edges of plates and disc shears for shearing strip steel. In the former, each disc blade is fixed on a separate transmission shaft in a cantilever way, and the number of the blades is two pairs, and the two pairs of the blades are used on finishing processing lines of medium plates, transverse cutting units of plate coils, continuous pickling lines and the like. The latter blades are generally fixed to two common shafts (and a few disc blades are fixed to a single shaft), and the number of blades is multiple, and the blades are used in longitudinal cutting machine set of plate rolls, continuous annealing and galvanizing production lines.

The circle shears are classified according to purpose: (1) the edge-cutting disc shear is used for shearing the side edge of the strip steel. The trimming circle shear can be used for a cold-rolled strip steel transverse cutting unit and a longitudinal cutting unit, (2) the trimming circle shear is used for longitudinal continuous shearing of strip wide steel strips, the structure of the trimming circle shear is determined to be a circle shear with two pairs of cutter heads or a circle shear with a plurality of pairs of cutter heads according to the requirement of workload, and the trimming circle shear is classified according to the transmission mode of the cutter heads: according to the transmission mode of the cutter head, the disc shear can be divided into a power shear and a tension shear. The tension shear means that the cutter head is not directly driven, and a tension roller or a coiler after shearing drags the strip steel to shear when the strip steel is pulled through the circle shear. The two shearing modes have the characteristics, so that a clutch is arranged in a transmission system of the disc shear, a power shearing or pulling force shearing mode can be adopted according to requirements, and the disc shear for trimming is generally composed of the following mechanisms: the cutter head adjusting mechanism comprises a left rack, a right rack, an upper cutter shaft, a lower cutter shaft, a base, a rack moving mechanism, a cutter head adjusting mechanism, a transmission device and the like, wherein 2 cutter rests are arranged on a common welding base, the opening degree of the cutter rests is adjusted by the aid of electric double-guide-screw rods moving along guide rails, and each cutter rest is provided with 2 cutter heads. The gap of the cutter head is adjusted by the nut on the upper cutter rod and the lower cutter rod which are driven by the motor, and the position of the cutter head is controlled by a sensor. The weight of the cutter head is adjusted longitudinally through the eccentric sleeve driven by the motor, and the position of the cutter head is controlled by the sensor. 1 strip passing roller and 1 pair of pressing rollers are arranged at the inlet of the circle shear and lifted by a hydraulic cylinder. Waste guide grooves are arranged on two sides of an outlet of the disc shear, edges on two sides of the strip steel are required to be orderly due to the structure of the disc shear, the width of the strip steel is strictly controlled, edges of two sides of the strip steel are trimmed on the disc shear, and cut edges are crushed on the edge crusher.

At present, a circle shear is needed to be used when the edge of a galvanized steel plate is cut, the opening degree of an operation side circle shear frame and a transmission side circle shear frame is one of important factors influencing the shearing quality of the steel plate, the opening degree is easy to drift along with the continuous shearing of the steel plate, the error between the width of the steel strip after the edge cutting and the set width is large, and under the condition of steel strip deviation, the edge cutting burr and the edge wire defect are easy to occur, and the processing precision is influenced.

Meanwhile, in the process of cutting, in order to bring away cutting heat and reduce friction between the cutter head and the steel plate as soon as possible, a cutter head oil dripping device is often arranged to drip oil to the cutter head, the purposes of cooling and lubricating and prolonging the service life of the cutter head are achieved, personnel can regularly clean or lubricate the cutter head in the process of dripping oil lubrication, the traditional lubrication method cannot achieve timely lubrication treatment on the cutter head, abrasion of the cutter head is further caused, the service life is shortened, the steel plate after cutting cannot meet the quality and precision requirements, unnecessary cost loss is generated, the oil dripping amount cannot be adjusted according to the processing state of the circle shear, the situation that oil dripping is excessive and waste and insufficient oil amount is easily caused, stable work of the circle shear is not facilitated, and therefore the problem is solved by the galvanized steel plate edge cutting circle shear.
