Description

Technical Field

[0001] The utility model relates to the technical field of plate shears, in particular to an anti-warping mechanism for a plate shear. Background Art

[0002] A plate shear, with the English name plate shears or guillotine shear, is a machine that uses one blade to make a reciprocating linear motion relative to another blade to shear a plate. It relies on the moving upper blade and the fixed lower blade, and uses a reasonable blade gap to apply a shearing force to metal plates of various thicknesses, so that the plates are broken and separated according to the required dimensions.

[0003] The utility model patent with the authorization announcement number CN210023897U discloses a plate shear, which includes a frame, a workbench and a shearing system. The workbench is placed on the frame. The shearing system includes a lower blade, an upper blade and a hydraulic cylinder. The lower blade is arranged on the workbench. The lower blade is slidably arranged in the vertical direction on the frame and forms a shearing opening with the lower blade. The hydraulic cylinder is arranged on the frame and is connected to the upper blade to drive the upper blade to slide up and down. A pressing member is arranged on the upper blade. The pressing member includes a pressing block and an elastic telescopic member. The elastic telescopic member is arranged on the upper blade. The pressing block is arranged on the elastic telescopic member. The distance from the bottom of the pressing block to the upper surface of the plate is less than or equal to the distance from the upper blade to the upper surface of the plate. It can press the upper surface of the plate during shearing processing to prevent the plate from warping and thus affecting the flatness of the shearing end face.

[0004] However, in the above device, only the pressing block arranged on the upper blade presses and fixes one side of the cutting position. When the plate is too long, the stress point is small, and the tail of the plate is not stressed. When processing, the tail will displace, thus affecting the processing quality. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-warping mechanism for a plate shear, which has the effect of preventing the plate from warping during the processing.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an anti-warping mechanism for a plate shear, including a frame. On one side of the frame, there is a plate shear body. Inside the plate shear body, there are an upper blade, a lower blade and a control component for controlling the lifting movement of the upper blade. On both ends of one side of the frame close to the plate shear body, there are symmetrically arranged fixing plates. On the side of the frame far from the plate shear body, there is an auxiliary pressing plate. The auxiliary pressing plate is horizontally arranged. On the frame, there is a lifting component for controlling the synchronous descent of the fixing plates to fix both ends of the plate and a moving component for controlling the movement of the auxiliary pressing plate towards the plate shear body.

[0007] By adopting the above technical solution, the fixing plate is arranged on one side close to the shearing machine body to press and fix the plate at the cutting position to prevent it from warping. The auxiliary pressing plate is arranged on the side far from the shearing machine body to press and fix the tail of the plate to further prevent it from warping. At the same time, by controlling the auxiliary pressing plate to move towards the shearing machine body through the moving component, automatic feeding of the plate can be realized.

[0008] The further setting of the present utility model is that: the lifting component includes a connecting rod fixedly connected to the top of the fixing plate.

The driving motor is fixedly connected to the frame.

[0013] By adopting the above technical solution, the driving motor controls the driving rod to rotate. The two driving blocks threadedly connected to the driving rod move synchronously and in opposite directions. Since a slope is arranged on the driving block and an inclined plane matching the slope is arranged on the connecting rod, at this time, the connecting rod moves in the vertical direction under the restriction of the slideway, thereby controlling the lifting of the fixing plate to realize the pressing and fixing of the plate.

[0014] The further setting of the present utility model is that: a vertically arranged spring is fixedly connected to the top of the connecting rod. One end of the spring far from the connecting rod is fixedly connected to the frame.

[0015] By adopting the above technical solution, the spring can help the connecting rod to reset.

[0016] A further setting of the present utility model is as follows: A sliding plate is slidably connected to the frame. The sliding plate is in an inverted "L" shape. A fixing rod is fixedly connected to the top of the auxiliary pressing plate. The fixing rod penetrates through the sliding plate, and the fixing rod is slidably connected to the sliding plate.

[0019] A further setting of the present utility model is as follows: A pressing spring is sleeved on the fixing rod. One end of the pressing spring is fixedly connected to the auxiliary pressing plate, and the other end is fixedly connected to the sliding plate.

[0020] By adopting the above technical solution, the auxiliary pressing plate presses and fixes the tail of the plate under the action of the pressing spring.

[0021] The beneficial effects of the present utility model are as follows:

[0022] 1. In the present utility model, the driving motor controls the rotation of the driving rod. The two driving blocks threadedly connected to the driving rod move synchronously and in opposite directions.
