Description

Technical Field

[0001] The utility model relates to the technical field of straightening machines, and more specifically to an adjustable straightening machine clamping mechanism. Background Art

[0002] A straightening machine is a device used to straighten metal profiles, bars, pipes, plates, etc. The straightening machine uses straightening rollers to squeeze bars and other materials to change their straightness. There are generally two rows of straightening rollers with varying numbers. When straightening the plates, the plates need to be limited to avoid tilting and shifting during the straightening process.

[0003] After searching, the utility model patent with announcement number CN218395380U discloses a positioning clamp mechanism of a straightening machine, including a straightening machine frame body, a support frame fixedly mounted on the straightening machine frame body, a positioning clamp device arranged on the support frame, the positioning clamp device comprising a driving motor, a forward screw rod fixedly mounted on the end of the output shaft of the driving motor, a reverse screw rod fixedly mounted on the end of the forward screw rod, sliders threadedly connected on the forward screw rod and the reverse screw rod, a limiting seat fixedly mounted on the bottom surface of the slider, two upper and lower symmetrical horizontal plates fixedly mounted on the two limiting seats, a plurality of limiting assemblies arranged between the two horizontal plates, the limiting assembly comprising a rotating shaft rotatably connected to the two horizontal plates, a top limiting device arranged on the top plate body of the support frame, and the top limiting device comprising a cylinder fixedly mounted on the support frame; the patent can perform positioning and appropriate clamping operations, which is beneficial to the stable transportation of the coil and convenient to use.

[0004] However, the above patents still have the following shortcomings: the unstraightened plate has a certain curvature, which makes it difficult to ensure that the side of the plate is exactly located in the limiting groove on the side of the limiting plate, and it is not convenient to limit the straightened plate. The unstraightened and straightened steel plates may be offset front and back, affecting the straightening effect. For this reason, we propose an adjustable straightening machine clamping mechanism.
