Description

Technical Field

[0001] The utility model relates to the technical field of plate shears, in particular to a plate shear for the production of electric power fittings. Background Technique

[0002] A plate shear is a machine that uses one blade to make a reciprocating linear motion relative to another blade to shear a plate. By adopting a reasonable blade gap, a shearing force is applied to metal plates of various thicknesses, so that the plates are broken and separated according to the required sizes. When electric power fittings are produced and processed, a plate shear is needed to cut them into the required shapes.

[0003] Most of the plate shearing blades in the existing plate shears are fixed by a plurality of screws, which makes it inconvenient to disassemble, maintain or replace the plate shearing blades. And after plates of different specifications are conveyed onto the plate shear, it is necessary to wait for the positioning mechanism to press and fix the plates, resulting in a reduction in the plate shearing efficiency. Therefore, the technical personnel in the field provide a plate shear for the production of electric power fittings to solve the problems raised in the above background technique. Content of the Utility Model

[0005] To achieve the above object, the utility model provides the following technical solution: A plate shear for the production of electric power fittings, including a workbench and side plates, the workbench is fixedly installed with the side plates, a conveying mechanism is arranged on the workbench, a hydraulic rod is installed on the upper part of the side plates, a tool holder is installed at the output end of the bottom of the hydraulic rod, a first through groove is transversely opened in the tool holder, a blade is inserted into the tool holder, a second through groove is transversely opened on the blade, a fixing plate is arranged on one side of the tool holder, an insertion plate is installed on the side of the fixing plate close to the tool holder, a third through groove is vertically opened in the insertion plate, an insertion block is inserted into the third through groove, an adjusting plate is arranged on the lower side of the fixing plate, a pressing plate is arranged on the lower side of the adjusting plate, a limiting bolt is installed on the upper side of the pressing plate, and a screw rod is threadedly sleeved on the fixing plate.

[0006] Preferably, the bottom of the screw rod is rotationally clamped with the adjusting plate, and the limiting bolt is slidably clamped with the adjusting plate.

[0007] Preferably, a pressing spring is sleeved on the periphery of the limiting bolt. The upper end of the pressing spring is in pressing contact with the bottom side wall of the adjusting plate, and the lower end of the pressing spring is in pressing contact with the pressing plate. The tool holder drives the fixing plate, the adjusting plate and the pressing plate connected to each other to press down at the same time. Therefore, before the blade contacts the plate, the pressing plate presses down and fixes the plate first, thereby improving the working efficiency.

[0008] Preferably, the blade is vertically inserted into the tool holder, and the first through groove is aligned with the second through groove.

[0009] Preferably, the insertion plate sequentially penetrates through the first through groove and the second through groove.

A blade 7 is inserted into the tool holder 6. A second through groove 701 is transversely opened on the blade 7. A fixing plate 8 is arranged on one side of the tool holder 6. A plug board 801 is installed on the side of the fixing plate 8 close to the tool holder 6. A third through groove 802 is vertically opened in the plug board 801. A plug block 14 is inserted into the third through groove 802. An adjusting plate 9 is arranged on the lower side of the fixing plate 8. A pressing plate 10 is arranged on the lower side of the adjusting plate 9. A limiting bolt 11 is installed on the upper side of the pressing plate 10. A screw rod 13 is threadedly sleeved on the fixing plate 8.

[0018] Please refer to Figure 2 、 Figure 3 . The bottom of the screw rod 13 is rotationally clamped with the adjusting plate 9. The limiting bolt 11 is slidably clamped with the adjusting plate 9. A pressing spring 12 is sleeved on the periphery of the limiting bolt 11. The upper end of the pressing spring 12 is in pressing contact with the bottom side wall of the adjusting plate 9. The lower end of the pressing spring 12 is in pressing contact with the pressing plate 10. The tool holder 6 drives the fixing plate 8 and the connected adjusting plate 9 and pressing plate 10 to press down at the same time. Thus, before the blade 7 contacts the plate, the pressing plate 10 presses down and fixes the plate first, thereby improving the work efficiency. The blade 7 is vertically inserted into the tool holder 6. The first through groove 601 is aligned with the second through groove 701. The plug board 801 sequentially penetrates through the first through groove 601 and the second through groove 701. When the end of the plug board 801 with the third through groove 802 protrudes from the first through groove 601, the plug block 14 is inserted into the third through groove 802 from top to bottom, so as to fix the blade 7. This structure makes the disassembly and assembly of the blade 7 very fast.

[0019] In this utility model, a conveying mechanism 2 is arranged on a workbench 1 for conveying plates. A side plate 4 is installed on one side of the workbench 1. A hydraulic rod 5 with its output end facing downwards is installed on the upper part of the side plate 4. A tool holder 6 is installed at the output end of the hydraulic rod 5. A first through groove 601 is horizontally formed in the tool holder 6. A blade 7 is inserted into the tool holder 6, and a second through groove 701 is formed in the blade 7. A fixing plate 8 is arranged on one side of the tool holder 6. An insertion plate 801 is installed on the side of the fixing plate 8 adjacent to the tool holder 6, and the insertion plate 801 sequentially penetrates through the first through groove 601 and the second through groove 701. When the end of the insertion plate 801 with a third through groove 802 protrudes from the first through groove 601, an insertion block 14 is inserted into the third through groove 802 from top to bottom, thereby fixing the blade 7. This structure enables the disassembly and assembly of the blade 7 to be very fast;

[0020] An adjusting plate 9 is installed on the lower side of the fixing plate 8. A pressing plate 10 is arranged on the lower side of the adjusting plate 9. The adjusting plate 9 and the fixing plate 8 are connected by a screw rod 13. The screw rod 13 is threadedly sleeved on the fixing plate 8, and the bottom end of the screw rod 13 is rotatably clamped with the adjusting plate 9. Rotating the screw rod 13 can adjust the height of the adjusting plate 9. A limiting bolt 11 is installed on the upper side of the pressing plate 10, and the limiting bolt 11 is sleeved on the adjusting plate 9 in a limiting manner. When the hydraulic rod 5 drives the tool holder 6 to press down the blade 7, the tool holder 6 simultaneously drives the fixing plate 8 and the connected adjusting plate 9 and pressing plate 10 to press down. Thus, before the blade 7 contacts the plate, the pressing plate 10 presses down and fixes the plate first, thereby improving work efficiency;

[0021] Since the fixing plate 8 and the adjusting plate 9 are connected by the screw rod 13, the pressing force on plates of different thicknesses can be adjusted by adjusting the height of the adjusting plate 9.
