Description

Technical Field

[0001] This utility model relates to the field of steel plate forming, and in particular to a base for a cold-bending steel forming machine. Background Technology

[0002] Cold bending of steel refers to the process of shaping steel strips into a specific shape and load-bearing capacity by passing them through a series of forming rollers. The steps in cold bending of steel strips are flattening, forming, welding, cooling, and finishing. Flattening, forming, and finishing are all achieved by the cooperation of two rollers, one above the other. Both rollers are rotatably mounted on the base of the cold bending steel forming machine. Adjacent rollers on the upper rollers are driven by a transmission belt, and a drive motor is installed at the front or rear roller on the base. The output shaft of the drive motor drives the roller to rotate via the transmission belt. Adjacent rollers on the lower rollers are also driven by a transmission belt. In this way, each roller on the base is driven by only one motor, and the rollers are driven by the transmission belt. This results in a certain speed difference between the rollers, which leads to unstable processing accuracy. At the same time, cooling water needs to be sprayed during processing, but currently there is no cooling water recovery system on the base, and the water is directly discharged and wasted.

[0003] In view of this, the inventor conducted in-depth research on the above-mentioned problems, which led to the creation of this invention. Utility Model Content
