Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing, and more specifically, to a thin steel plate cutting device. Background Art

[0002] Steel plates are flat plates that can be directly rolled or cut from wide steel strips. With the development of the economy, the application of steel plates is becoming more and more extensive. Steel plates are widely used in construction, automobiles, bridges, boilers, pressure vessel plates and multi-layer high-pressure vessels. In this steel plate shearing machine, when it is necessary to take out the steel coil on the material roller, the steel coil is released by rotating the unloading machine. This method has certain problems because the surface of the steel coil is relatively smooth. When there are fewer steel coils on the outside of the material roller, the friction between the steel coil and the material roller is small, and the rotating material roller is difficult to drive the steel coil on its outside to rotate and release the material, resulting in the problem of difficulty in unloading.

[0003] In order to solve the above problems, patent document publication number CN217859061U discloses a steel plate shearing device, comprising a base, a roller is arranged at one end of the base, a U-shaped frame is arranged on the upper surface of the base, a cutting structure is arranged on the U-shaped frame, a hydraulic telescopic rod is arranged at the end of the base away from the roller, a clamping assembly is arranged at the telescopic end of the hydraulic telescopic rod, and a support pad is arranged on the upper surface of the base.

[0004] When the above device is in use, one end of the steel coil is extended to the inner side of the U-shaped clamp, and the pulling plate is released. Under the action of the spring force, the extrusion block presses one end of the steel coil against the inner side of the U-shaped clamp, and the steel coil can be released from the outer side of the material roller by contraction of the hydraulic telescopic rod, thereby achieving a stable material discharge effect. However, since it has no straightening device, especially for the steel coil, during the process of unwinding the steel plate, it is easy to bend due to the winding itself, resulting in an unsatisfactory shearing effect. In addition, during the shearing process, it is impossible to perform shearing at a determined distance, which affects the shearing accuracy. Utility Model Content

A plurality of support rollers 15 are rotatably installed on the surface of the support frame 14, and the side of the support platform 18 away from the unwinding shaft 12 is an inclined surface.

[0022] Due to the inclined surface of the support platform 18, after the steel plate coil 13 is sheared, the steel plate coil 13 is allowed to slide down through the inclined surface through the inclined surface of the support platform 18, thereby achieving unloading.

[0023] Among them, the straightening device 2 includes a leveling frame 21, which is fixedly installed on the top of the support frame 14.

A displacement sensor is arranged on the side of the moving seat 35, and the displacement sensor is electrically connected to the moving motor 33.

[0027] Since the displacement sensor on the movable seat 35 is electrically connected to the movable motor 33, when adjusting the shear distance of the steel plate coil 13, the fixed cylinder 37 is started, so that the fixed clamping plate 36 descends to the surface of the movable seat 35 to fix the steel plate coil 13. Subsequently, the movable motor 33 is started, so that the rotating screw 34 rotates, and the movable seat 35 moves to the right on the surface of the movable frame 31. When the displacement sensor senses the distance from the movable seat 35 to the support frame 14, it transmits an electrical signal to the movable motor 33 to stop the movable motor 33, and the fixed cylinder 37 makes the fixed clamping plate 36 rise, and the steel plate coil 13 on the movable seat 35 loosens, and the movable motor 33 controls the movable seat 35 to move toward the direction of the support frame 14, and repeats this process.
