Description

Technical Field

[0001] This utility model belongs to the field of cold-rolled sheet processing technology, specifically relating to a mechanical equipment assembly device for cutting cold-rolled sheets. Background Technology

[0002] The outer casing of mechanical equipment is often assembled using cold-rolled steel sheets as raw materials. During processing, cold-rolled steel sheets are typically cut into patterns and shapes using a laser cutter. The laser outputs a high-energy-density laser beam, which is focused on the surface of the workpiece, causing the area irradiated by the ultra-fine focal spot to melt and vaporize instantly, thus achieving cutting. Current laser cutting machines generally place the workpiece on a processing table with a discharge port on the upper side. Cutting blades are equidistantly positioned above the discharge port. The cold-rolled steel workpiece is usually placed directly on the cutting blades, and the cut fragments fall directly through the blades from the discharge port. However, when the cold-rolled steel sheet is cut by the laser beam, a large number of vaporized metal particles are generated. As these particles pass between the cutting blades, they adhere to the surface of the blades due to cooling, requiring regular disassembly and cleaning. Currently, laser cutting machines lack a mechanism for daily cleaning of the cutting blades. Regular cleaning results in a thick layer of particles adhering to the surface, making cleaning laborious and failing to extend the cleaning and maintenance intervals. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a mechanical equipment assembly device for cutting cold-rolled steel sheets. This device solves the problem that when cold-rolled steel sheets are cut by a laser beam, a large number of metal vaporized particles are generated. As these particles pass between the blades, they adhere to the surface of the blades due to cooling and adhesion. The blades need to be disassembled and cleaned regularly. Currently, laser cutting machines do not have a mechanism for daily cleaning of the blades. Regular cleaning of the blades results in a thick layer of particles adhering to the surface, which is laborious and does not extend the cleaning and maintenance time of the blades.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a mechanical equipment assembly cold-rolled sheet cutting device, comprising a machine base, bases evenly arranged on the lower side of the machine base, a control unit arranged on one side of the machine base, a material feeding chute extending through the upper side of the machine base, blades evenly arranged at the upper opening of the material feeding chute, electric guide rails on both sides of the machine base, electric sliding groups arranged on the upper side of each electric guide rail, electric guide rails on the second side between the electric sliding groups, a laser generator slidably arranged on the upper side of the second electric guide rail, and motors symmetrically arranged on the side of the machine base. The output end of the motor is connected to the inner side of the material chute by a threaded rod. Sliding grooves are provided on both sides of the inner side of the material chute. Cleaning mechanisms are slidably arranged side-by-side inside the sliding grooves, with the cleaning mechanisms arranged in opposite directions. Each cleaning mechanism includes a bar and a cleaning blade. The bar is slidably connected to the sliding groove. Cleaning blades are equidistantly arranged on the upper side of the bar, each corresponding to a blade strip. The cleaning blades of the two cleaning mechanisms are respectively positioned to fit against both sides of the blade strip. A connecting plate is provided on the lower side of the bar corresponding to the threaded rod, and the connecting plate is threadedly connected to the threaded rod.

The connecting plate will drive the cleaning mechanism to move repeatedly along the sliding groove. When the cleaning mechanism moves, the cleaning blades of the two cleaning mechanisms will respectively stick to both sides of the blade strip to scrape and clean the blade strip. The scraped metal particles will fall through the discharge chute, which can perform daily cleaning and maintenance on the surface of the blade strip, avoid the accumulation and adhesion of metal particles, extend the cleaning cycle of the blade strip, and reduce the difficulty of cleaning the blade strip.
