Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a feeding device for punching steel profiles. Background Technology

[0002] Existing automated steel section production lines include punching and shearing machines for processing steel sections and conveyor rails that transport the steel sections into the punching and shearing machines. When placing the steel sections onto the conveyor rails, they are generally transported by manual lifting or by crane. Only one steel section can be transported at a time, which is inconvenient and inefficient. At the same time, workers need to be highly focused during the handling of steel sections to avoid accidental injuries or other safety accidents. When using manual handling, the labor intensity of workers is high, which not only endangers the health of workers but also results in excessive labor costs and increases overall costs.

[0003] Patent No. CN201920771348.9 discloses a steel section feeding device, which differs in that it includes a conveying guide rail, a feeding device, and a transfer device disposed between the conveying guide rail and the feeding device; the conveying guide rail is connected to a punching and shearing machine and conveys the steel section into the punching and shearing machine; the feeding device has a placement part for placing the steel section on the side near the conveying guide rail; the transfer device includes a first cylinder part, a second cylinder part, a guide rod part, and a feeding fork part fixed to the upper end of the guide rod part; the first cylinder part can control the guide rod part to move up and down, the second cylinder part can control the guide rod part to move along the direction of the steel section transfer line, and the feeding fork part moves with the guide rod part to transfer the steel section located on the placement part to the conveying guide rail. The material transfer device requires three cylinders to work together to transfer the material from the feeding device to the feeding guide rail. The equipment cost is high and the installation work is extensive. The transfer device needs to first lift the material to transfer it to the fork, then move it horizontally to transfer it to the top of the conveyor rail, and then lower it to transfer it to the conveyor rail. The process is complicated and the efficiency is low. Therefore, this utility model proposes a feeding device for steel blanking. Utility Model Content
