[0002] In the process of ship production and processing, punching equipment is often used to perform punching processing on parts. At present, most punching equipment adopts the cooperation of upper and lower molds to operate, and drives the upper mold to move in the lower mold through a hydraulic cylinder to complete the punching operation of the parts. However, in these punching equipment, the upper and lower molds are usually fixed to the connection points inside the equipment by fixing bolts. Due to the differences in the size of parts during the processing, the corresponding lower mold needs to be replaced frequently. When the lower mold is fixed with fixing bolts, the disassembly and re-fixing process is relatively complicated, which makes the lower mold replacement process cumbersome and consumes a lot of time. To this end, we propose a punching device for ship processing parts. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution: a punching device for ship processing parts, including a workbench 1, a support frame 2 symmetrically distributed on the left and right is welded and fixed at the bottom of the workbench 1, the support frame 2 is used to support and fix the workbench 1, a fixing mechanism 3 is fixedly assembled inside the workbench 1, the fixing mechanism 3 is used to limit and fix the lower mold 4, and the lower mold 4 is detachably fixed to the surface of the workbench 1 by setting the fixing mechanism 3. Since it is necessary to punch parts of different sizes during the production and processing of ships, it is necessary to use a lower mold 4 that matches the size and shape of the parts to limit and fix the parts according to the different sizes and shapes of the parts. The device redesigns the fixing mechanism 3 and the lower mold 4, so that the operation is simpler and more convenient when the lower mold 4 is disassembled and installed between the workbench 1, and the replacement time of the lower mold 4 is saved.

[0023] like Figure 2As shown in the figure, the fixing mechanism 3 includes an assembly groove 31, which is symmetrically opened in the workbench 1 on the left and right sides. A lifting frame 32 that can be lifted up and down along the assembly groove 31 is installed in the assembly groove 31. A fixing block 33 that is tilted and arranged at a certain angle is welded and fixed on the surface of the lifting frame 32. A positioning frame 34 is detachably fixedly connected to the top of the fixing block 33 by a first fixing screw. A positioning pin 35 is welded and fixed at the end of the positioning frame 34. By moving the lifting frame 32 up and down in the assembly groove 31, the positioning pin 35 can be controlled to be inserted into or removed from the lower mold 4, so as to achieve the limit fixation of the lower mold 4.

[0024] A fixing frame 36 is welded and fixed to the side wall of the inner cavity of the support frame 2, and an assembly block 37 is welded and fixed on the surface of the fixing frame 36 in a symmetrical manner at the front and rear. A telescopic cylinder 38 is fixedly assembled on the side wall of the assembly block 37, and the output end of the telescopic cylinder 38 is fixedly connected to the bottom of the lifting frame 32. The telescopic cylinder 38 is supplied with air by an external air pump and its output end is controlled. The lifting frame 32 can be driven to move up and down quickly in the assembly groove 31 through the telescopic cylinder 38. The telescopic cylinder 38 symmetrically distributed at the front and rear is used to drive the lifting frame 32 to move, so that the movement of the lifting frame 32 is faster. A guide shaft 39 that runs through the lifting frame 32 is welded and fixed to the top of the assembly block 37. By setting the guide shaft 39, the lifting stroke of the lifting frame 32 can be limited, thereby improving the accuracy of the lifting stroke of the lifting frame 32 in the assembly groove 31.

[0025] like Figure 3 As shown in , positioning holes 41 are opened at the four corners of the lower mold 4, and the positioning holes 41 are used to insert the positioning pins 35. When the positioning frame 34 drives the positioning pins 35 to be inserted into the positioning holes 41, the lower mold 4 can be fixed on the surface of the workbench 1.

[0026] like Figure 3 As shown in the figure, pre-fixing blocks 5 are integrally formed at the four corners of the bottom of the lower mold 4, and pre-fixing holes 6 are opened on the surface of the workbench 1. By setting the pre-fixing blocks 5 and the pre-fixing holes 6, the pre-positioning between the lower mold 4 and the workbench 1 can be achieved, thereby improving the accuracy of the assembly position of the lower mold 4 and facilitating the insertion of the positioning pin 35 into the positioning hole 41.

[0027] like Figure 2 As shown in , a waste collection trough 7 is provided in the middle of the workbench 1, and the waste collection trough 7 runs through the workbench 1. A waste collection vehicle 8 is inserted between the two support frames 2 below the workbench 1. The bottom of the lower mold 4 is hollow, and its inner cavity is connected to the waste collection trough 7. The waste generated during the punching process of the parts enters the waste collection vehicle 8 through the waste collection trough 7 for collection, which is convenient for the subsequent centralized treatment of the waste. Figure 5As shown in the figure, a sponge layer 81 is pasted and fixed to the inner cavity side wall of the waste collection vehicle 8. By providing the sponge layer 81, the collision between the waste and the interior of the vehicle body during the waste collection process can be reduced, and the noise generated during the waste collection process can be reduced.

[0028] like Figure 1 As shown in the figure, an assembly frame 10 is welded and fixed on the surface of the workbench 1, and a lifting mechanism 9 is fixedly installed on the top of the assembly frame 10. The action end of the lifting mechanism 9 is detachably fixedly installed with an upper mold 11. The upper mold 11 is driven by the lifting mechanism 9 to move downward along the lower mold 4 to realize the stamping operation of the parts in the lower mold 4.

[0029] The lifting mechanism 9 includes a first hydraulic cylinder 91, the number of the first hydraulic cylinder 91 is two, and the two first hydraulic cylinders 91 are fixedly assembled on the top of the assembly frame 10 in a left-right symmetrical manner. The output ends of the two first hydraulic cylinders 91 penetrate the assembly frame 10 and are fixedly connected to a mounting frame 92. A second hydraulic cylinder 93 is fixedly assembled in the mounting frame 92. Figure 4 As shown in , the output end of the second hydraulic cylinder 93 is fixedly connected to a connecting block 94, and a connecting groove 111 is provided on the top of the upper mold 11. After the connecting block 94 is inserted into the connecting groove 111, the connecting block 94 is fixedly connected to the upper mold 11 by a second fixing screw. The first hydraulic cylinder 91 and the second hydraulic cylinder 93 are respectively connected to external hydraulic pipelines, and the lifting and lowering of their output ends are respectively controlled by external hydraulic pipelines. The output end of the first hydraulic cylinder 91 is moved to adjust the height position of the mounting frame 92 and the upper mold 11 to facilitate the connection between the upper mold 11 and the lower mold 4. The second hydraulic cylinder 93 drives the connecting block 94 and the upper mold 11 to move downward, completing the punching operation of the upper mold 11 on the parts in the lower mold 4.

[0030] The left and right ends of the upper mold 11 are respectively integrally formed with a limiting sleeve 121, and the left and right ends of the lower mold 4 are respectively integrally formed with a limiting shaft 122. When the upper mold 11 and the lower mold 4 are combined, the limiting shaft 122 passes through the limiting sleeve 121. The limiting assembly 12 composed of the limiting sleeve 121 and the limiting shaft 122 is used to limit the upper and lower movement strokes of the upper mold 11, thereby improving the accuracy of the moving stroke of the upper mold 11 during the punching operation of the parts, thereby improving the accuracy of the punching process.

[0031] Working principle: In the application process of the utility model, the lower mold 4 is replaced more frequently due to the different sizes of the processed parts. The upper mold 11 is adapted to most of the lower molds 4, so the upper mold 11 is replaced less frequently. The lower mold 4 of the corresponding size is selected according to the size of the parts to be processed in batches. First, the telescopic cylinder 38 is controlled to drive the lifting frame 32 to move upward in the assembly groove 31, so that there is a certain height between the positioning pin 35 and the pre-fixing hole 6, and then the lower mold 4 is assembled on the surface of the workbench 1. The pre-fixing block 5 at the bottom of the lower mold 4 is first inserted into the pre-fixing hole 6 to achieve pre-positioning between the lower mold 4 and the workbench 1;

[0032] Then, the telescopic cylinder 38 is controlled to drive the lifting frame 32 to move downward. While the positioning frame 34 limits and fixes the lower mold 4, the positioning pin 35 is inserted into the positioning hole 41 to further enhance the positioning effect of the lower mold 4. Then, the first hydraulic cylinder 91 of the lifting mechanism 9 is controlled to move to lower the upper mold 11 to connect it with the lower mold 4. Subsequently, the parts that need to be punched will be inserted into the lower mold 4. The second hydraulic cylinder 93 is controlled to drive the upper mold 11 to reciprocate along the limiting axis 122 to realize the punching operation of the parts. The waste generated during the punching process enters the waste collection trough 7 into the waste collection vehicle 8 for collection, which is convenient for subsequent centralized processing.
