[0002] The hydraulic support shield beam bending device is a device used in underground operations such as coal mines to accurately bend shield beams. The shield beam is one of the key components of the hydraulic support, and its structure and performance directly affect the stability and safety of the entire support system.

[0003] In the existing bending device for processing the support beam of the press-bend bracket, the bracket to be press-bent is limited by the limiting plates at both ends, and then the bracket to be press-bent is bent by the press-bending device.

[0004] However, in actual use, this device still has some defects. The limit plates at both ends of this device are fixed at both ends, and the fixed limit plates cannot be adjusted according to the shielding beams of different sizes or shapes, which limits the adaptability of the equipment to different workpieces. When it is necessary to process shielding beams of various specifications, the limit plates fixed at both ends may lead to reduced production efficiency or require additional equipment to meet production needs.

[0005] Therefore, it is necessary to provide a bending device for processing a pressure support shield beam to solve the above technical problems. Utility Model Content

[0009] Preferably, positioning plates are welded at the upper and lower ends of the arc-shaped plate, and the arc-shaped plate is detachably mounted on the end side of the processing table through positioning bolts and the positioning plates.

[0010] Preferably, a magnetic plate is further provided in the limiting groove formed on the processing table. The magnetic plate is fixedly installed in the limiting groove and the circuit is controlled by a control switch.
