Technical Field

The utility model belongs to the technical field of belt conveyor makes, in particular to belt conveyor bearing roller crossbeam bending forming die.

Background

The belt conveyer is a friction-driven machine for continuously conveying material and is mainly composed of machine frame, conveying belt, supporting rollers, supporting roller cross beam, tension device and driving device. The traditional processing mode of the roller beam of the belt conveyor is manually completed by four processes of angle steel marking, cutting, bending and welding, has more operation processes and low working efficiency, and can only be suitable for single-piece and small-batch customized production; the roller cross beam manufacturing in large batch mostly adopts an integral one-step bending forming process, a special forming die is needed, however, the forming die is usually complex in structure, large in size, heavy in weight, long in manufacturing period and high in cost, one forming die is only suitable for an upper aligning roller cross beam of one specification, and the heavy forming die is very troublesome to install and replace on a press machine.
