Description

Technical Field

[0001] This utility model belongs to the technical field of bending devices, specifically relating to a right-angle bending device. Background Technology

[0002] When processing pipe or sheet metal workpieces, it is sometimes necessary to bend them to 90 degrees to meet the requirements of the installation environment. Compared with manually bending workpieces, right-angle bending equipment can not only ensure that the angle of each bend is accurate, but also significantly improve production efficiency.

[0003] A search revealed that Chinese Patent No. CN 221869824 U discloses a 90° bending device, relating to the field of bending devices. This 90° bending device includes a frame, a hydraulic cylinder fixedly connected to the frame, a push block fixedly connected to the piston rod of the hydraulic cylinder, and two angle blocks fixedly connected to the frame, forming a 90° angle between them. Multiple sets of first and second slots are provided on both the push block and the angle blocks. A first push post is detachably connected to the first slot, and a second push post is detachably connected to the inner shell of the second slot. In this 90° bending device, the workpiece to be bent is placed on the frame, and then the hydraulic cylinder is activated to drive the push block to slide towards the angle blocks. The push block compresses the workpiece, causing it to shrink between the two angle blocks, thus bending the workpiece to 90°.

[0004] However, in the actual use of this 90° bending device, since the pushing force of the pusher on the workpiece is horizontal, the workpiece placed between the pusher and the angle block is very prone to vertical deviation during the horizontal extrusion process. This not only affects the product accuracy and quality of the workpiece, but the deviated workpiece will also cause wear or damage to the mold, resulting in a reduction in the service life of the mold. Therefore, a right-angle bending device is needed to solve the above problems. Utility Model Content
