Device Profile
● HJY-60B hydraulic straightening machine is a kind of heavy steel flange straightening equipment developed based on the needs of the market and users. The main body adopts the overall structure, the upper straightening wheel adopts the axle box structure, and the main driving wheel adopts the top method, so that the straightening pressure can reach 1500KN, and the effect is stable. It is used for welding deformation of H-beams of large thick flange plates. In the main drive, a large universal coupling, cylindrical gear reducer, and hydraulic motor are used, and the transmission torque reaches more than 10,000 N• meters.
● In other auxiliary functions, we have added a scale display device and a digital display of the correction amount on the main engine. The front and rear of the main engine have been added with hydraulic floating rollers. The height of the front and rear conveying rollers can be reduced, which increases the stability and safety of use.
● This machine mainly includes the main engine part, front and rear hydraulic floating roller table, electrical system and hydraulic system.
● The main engine part is composed of an integral structural main body, a web centering mechanism, a left and right upper pressure wheel adjustment mechanism, a hydraulic lifting and straightening transmission system and a main engine roller table.
● The main drive mechanism is transmitted to the main drive roller through hydraulic motor, cylindrical gear reducer, universal drive shaft; when working, the main drive roller is lifted and lowered by the bottom hydraulic cylinder, together with the upper pressure roller, to correct the welding deformation of the wing plate; The centering mechanism is divided into two groups at the front and back, one side is operated by the screw handle, and the other side is clamped by hydraulic pressure (when using, it is not necessary to press too tightly), so that the workpiece web is basically in the middle of the main drive wheel.
