Abstract
Description
Technical Field
[0001] This utility model relates to the field of shearing machine technology, and more specifically to a plate positioning device for a shearing machine. Background Technology
[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. It employs a moving upper blade and a fixed lower blade, with a suitable blade gap, to apply shearing force to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions. During the use of a shearing machine, the sheet metal needs to be positioned.
[0003] A search revealed an existing patent (publication number: CN216882006U) that discloses a plate positioning device for a shearing machine. During operation, a second motor, a first motor, and plate limiting clamps are used. The plate is placed between the two clamps. The second motor is then activated, causing two second nut blocks at both ends of a bidirectional threaded rod to move towards each other in a first groove. This further clamps the plate. An electric actuator is then activated, causing a plate fixing clamp to move downwards, further securing the plate. The first motor is then activated, causing the threaded rod to rotate. This rotation causes the first nut blocks to slide in the second groove, further moving the upper and lower blades and positioning the shearing position. This automatic positioning and shearing eliminates the need for manual adjustment, improving the device's safety. However, in the process of realizing this utility model, the inventors discovered the following problems with the prior art: When the above-mentioned plate positioning device for shearing machine cuts the plate, it uses the two ends of the plate to be flush with the surface of the plate limiting clamp. Then, when cutting the plate, it can only satisfy the effect of parallel cutting of the plate, that is, it cannot quickly adjust the positioning and cutting angle. When cutting the plate at an angle, it is difficult to meet the cutting and processing task, and it has the disadvantage of limited applicability.
[0004] In view of this, the present invention proposes a plate positioning device for a shearing machine to solve this problem. Utility Model Content

[0034] It is worth noting that the shearing machine uses a plate positioning device to bring one end of the rectangular plate flush with the inner wall of the clamping frame 7.

Then, the first servo motor 4 drives the transverse lead screw 3 to rotate, thereby moving the transverse frame 5.

Based on the meshing of the worm gear 12 and the worm wheel 13, the vertical shaft 10 can be driven to rotate, thereby adjusting the angle of the clamping frame 7. This allows for the adjustment of the angle of the sheet metal, meeting the needs of tilting the sheet metal and enhancing the applicability of the shearing machine.
[0043] A pointer 16 is provided at the top of the vertical axis 10, and an angle marking line 17 is provided on the upper surface of the connecting platform 6 with the central axis where the vertical axis 10 is located as the center. The pointer 16 and the angle marking line 17 are positioned correspondingly.
[0044] It is worth noting that by setting the pointer 16 and the angle marking line 17, the deflection angle of the vertical axis 10 and the clamping frame 7 can be accurately marked.
[0045] The connecting platform 6 is movably mounted on the surface of the transverse frame 5, and the top of the transverse frame 5 is rotatably connected to the longitudinal lead screw 25.
