[0024] Refer to Figures 1-4 , an embodiment of a punching device for die steel plates with replaceable punching heads according to the present utility model includes: a base 1, a rotating clamping device 4 is provided on the upper surface of the base 1, a support plate 5 is fixedly connected to the rear wall of the base 1, a first hydraulic rod 6 is fixedly connected through the top end of the support plate 5, the bottom end of the movable end of the first hydraulic rod 6 is fixedly connected with a first motor 7, the output end of the first motor 7 is fixedly connected with a quick disassembly and assembly mechanism 8, and a drill rod 3 is installed on the quick disassembly and assembly mechanism 8;

[0025] The quick disassembly and assembly mechanism 8 includes a housing 801 and two symmetrically arranged connecting rings 803. An installation hole 8011 is provided at the bottom end of the housing 801, and a limiting hole 8012 is provided on the side wall of the housing 801. The limiting hole 8012 communicates with the installation hole 8011. A positioning protrusion is provided on the side wall of the drill rod 3, and a positioning groove is provided on the inner side wall of the installation hole 8011 to facilitate positioning and installation. A spring 804 is fixedly connected between the opposite surfaces of the two connecting rings 803. A bolt 805 is fixedly connected to the side wall of the outer connecting ring 803. The side wall of the bolt 805 is slidably connected to the inner wall of the limiting hole 8012. A fixing plate 802 is fixedly connected to the right side of the housing 801. A limiting bolt 806 is threadedly connected through the fixing plate 802. A threaded hole 8051 is provided on the bolt handle of the bolt 805, and the threaded hole 8051 is adapted to the limiting bolt 806;

[0026] The rotary clamping device 4 includes a second motor 401. A support ring 2 is provided on the outer wall of the second motor 401. The bottom end of the support ring 2 is fixedly connected to the upper surface of the base 1, and the top end of the support ring 2 is rotatably connected to the bottom end of the bottom plate 402. The output end of the second motor 401 is fixedly connected to the bottom plate 402. Slot holes are evenly provided on the upper surface of the bottom plate 402 to provide conditions for drilling. Two side plates 403 are symmetrically and fixedly connected to the bottom plate 402. A second hydraulic rod 404 is fixedly connected through the side walls of the side plates 403. Clamping plates 405 are fixedly connected to the movable ends of the second hydraulic rods 404. A third hydraulic rod 406 is fixedly connected to the lower surface of the top end of each clamping plate 405. Rubber push blocks are fixedly connected to the bottom ends of the third hydraulic rods 406 to protect the steel plate. By providing the rotary clamping device 4 and the support ring 2, when clamping the steel plate, place the steel plate on the bottom plate 402, and at the same time start the two second hydraulic rods 404 to push the two clamping plates 405 to clamp the steel plate. After clamping and fixing, start the third hydraulic rod 406 to push the push block to press the upper surface of the steel plate to provide stable conditions for drilling. When it is necessary to change the drilling position of different parts of the steel plate, the two second hydraulic rods 404 can cooperate with each other to push the clamping plates 405 to change the drilling position while the steel plate is clamped. If it is necessary to rotate and change the orientation of the steel plate, start the second motor 401 to drive the bottom plate 402 to rotate and drive the steel plate to rotate, which is not only applicable to various sizes but also improves the drilling efficiency; by providing the quick disassembly and assembly mechanism 8 and the drill rod 3, when it is necessary to replace the drill rod 3, rotate the limiting bolt 806 to disengage it from the threaded hole 8051. Next, pull out the bolt 805 outward to disengage it from the through hole of the drill rod 3 and release the limit on the drill rod 3, then the drill rod 3 can be replaced. When replacing, after inserting the drill rod 3 into the installation hole 8011, loosen the bolt 805, and the spring 804 contracts to drive the bolt 805 to reset and insert into the through hole of the drill rod 3 to limit the drill rod 3. Finally, thread the limiting bolt 806 and the threaded hole 8051 to complete the limit on the bolt 805, which not only improves the disassembly and assembly efficiency but also ensures the stability of the rotation of the drill rod 3.

[0027] Working principle: When in use, place the steel plate on the bottom plate 402, and start the two hydraulic rods 404 at the same time to push the two clamping plates 405 to clamp the steel plate. After clamping and fixing, start the hydraulic rod 406 to push the push block to press the upper surface of the steel plate to provide stable conditions for drilling. When different parts of the steel plate need to be drilled, the two hydraulic rods 404 can cooperate with each other to push the clamping plates 405 to change the drilling position when the steel plate is clamped. When drilling, the hydraulic rod 6 pushes the motor 7 downward, and the motor 7 drives the drill rod 3 to rotate to drill the steel plate. If the steel plate needs to be rotated to change its position, start the motor 401 to drive the bottom plate 402 to rotate and drive the steel plate to rotate. It is not only suitable for a variety of sizes, but also improves the drilling efficiency.

[0028] When the drill rod 3 needs to be replaced, the limiting bolt 806 is rotated to disengage it from the screw hole 8051. In the next step, the differential plug 805 is pulled outward to disengage it from the through hole of the drill rod 3, and the limiting of the drill rod 3 is released, so that the drill rod 3 can be replaced. When replacing, after the drill rod 3 is inserted into the mounting hole 8011, the plug 805 is loosened, and the spring 804 contracts to drive the plug 805 to reset and insert it into the through hole of the drill rod 3, thereby limiting the drill rod 3. Finally, the limiting bolt 806 is threadedly connected to the screw hole 8051 to complete the limiting of the plug 805, which not only improves the disassembly and assembly efficiency, but also ensures the stability of the rotation of the drill rod 3.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
