Abstract
Description
Technical Field
[0001] The utility model relates to a cold-rolled strip steel trimming shear blowing and brushing device, which is suitable for the technical field of cold-rolled strip steel trimming shear equipment in the metallurgical industry. Background Art
[0002] The edge trimming shear is one of the important equipment in the production process of cold-rolled strip steel. It is mainly composed of a deviation correction roller, a stabilizing roller, a disc shear, an edge trimming shear, a material guide chute, a material discharge port, a scrap belt, a flip scrap hopper, a deburring machine and other equipment. It can achieve the cutting and breaking of the edge of the steel coil, optimize the edge quality of the strip steel, and meet the customer's demand for the width of the steel coil.
[0003] Since strip trimming is a continuous production, once the trimming shear has problems, a large number of unplanned products will be produced, resulting in cost losses and affecting product delivery. During the strip trimming process, the disc shear causes blade wear and thermal deformation due to long-term cutting, which causes blade aging and affects the shearing of the strip. In addition, iron filings and zinc powder will be generated during the cutting process. If not cleaned up in time, it will affect the surface quality of the strip. Utility Model Content
[0004] The utility model aims to provide a cold-rolled strip trimming shears blowing and brushing device, which can effectively reduce the overheating of the disc shears blade caused by long-term cutting, ensure the stable performance of the disc shears blade, and at the same time can timely clean the iron filings and zinc powder generated in the cutting process, thereby solving the problems existing in the background technology.
[0005] The technical solution of the utility model is:
[0006] A cold-rolled strip trimming shears and a blowing and brushing device comprises a brush head bracket, a brush head, an oil guide pipe, a purge bracket, a purge nozzle, an air guide pipe and an oil pot. The brush head and the purge nozzle are respectively arranged on both sides of the disc shear, the brush head is fixed on the brush head bracket, one end of the oil guide pipe is connected to the brush head, and the other end of the oil guide pipe is connected to the oil pot; the purge nozzle is fixed on the purge bracket, and the purge nozzle is connected to the air guide pipe.
[0007] The brush head is arranged obliquely, the lower end of the brush head contacts the cutting edge of the disc shear, and the higher end of the brush head is connected to the oil guide pipe.
[0008] The position of the oil pot is higher than that of the brush head.
[0009] The oil pot is filled with kerosene.
[0010] The blowing direction of the blowing nozzle is along the radial direction of the disc shear and toward the shearing edge of the disc shear.
[0011] The air guide pipe is connected with the air source main pipe.
[0012] The beneficial effects of the utility model are: it can effectively reduce the overheating of the disc shear blade caused by long-term cutting, ensure the stable performance of the disc shear blade, and reduce the probability of adze and aging; at the same time, it can timely clean the iron filings and zinc powder generated in the cutting process, and improve the surface quality of the strip steel.
