[0001] The utility model relates to the field of nonferrous metal punching, in particular to a punching tool for nonferrous metal rolled material extrusion pieces. Background Art

[0002] The non-ferrous metal rolling and punching tool is a tool device used for rolling and punching non-ferrous metals (such as copper, aluminum, etc.). This tool usually includes components such as molds, fixtures and support structures, which are used to apply pressure on metal sheets or profiles to produce processing effects such as shape, size or holes. The non-ferrous metal rolling and punching tool can realize the forming processing of non-ferrous metal products, which is widely used in automobile manufacturing, aerospace, home appliances and other industries.

[0003] During the punching process of existing non-ferrous metals, residual materials will continue to accumulate on the surface of the mold, causing blockage and wear of the mold, and will clog the punching tool, thereby affecting production efficiency and product quality. This accumulated residual material will also damage the surface of the product, bringing many inconveniences and challenges to the production process. Utility Model Content

[0029] In order to further understand the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Combination Figure 1 and Figure 2 ,as well as Figure 5 The utility model provides a punching tool for non-ferrous metal rolled material extrusion parts, including a pressing plate 1 and a rolling mechanism 2, and a workpiece 5 to be processed, wherein the pressing plate 1 is fixedly provided with the rolling mechanism 2 for pressing the workpiece 5 at the center, and a punching mechanism 4 for punching the workpiece 5 is placed on the surface of a base 3;

[0031] The calendering mechanism 2 includes a connecting sleeve 21 for connecting to a pressing device, and an extrusion component 22 for extruding the material is installed inside the connecting sleeve 21;

[0032] The punching mechanism 4 includes a first mounting seat 41, a cylindrical knife 411 is fixedly arranged at the center of the first mounting seat 41, a second mounting seat 42 is also mounted on the bottom surface of the first mounting seat 41, and a recycling component 43 for recycling waste is fixedly arranged inside the second mounting seat 42;

[0033] The connecting sleeve 21 drives the pressing plate 1 to be pressed down while transporting the workpiece 5 to the top of the first mounting seat 41. The connecting sleeve 21 and the pressing plate 1 can be installed on the existing pressing equipment. When the extrusion component 22 contacts the surface of the workpiece 5, it will apply a vertical downward force to the workpiece 5, so that the bottom surface of the workpiece 5 contacts the cylinder knife 411 at the center of the first mounting seat 41, so that a part of the workpiece 5 is rolled and cut off. In this process, the extrusion component 22 sends the remaining material cut off from the workpiece 5 to the recovery component 43, so as to avoid the remaining material from punching non-ferrous metals to be randomly accumulated on the mold surface.

[0034] Combination Figure 3 The connecting sleeve 21 is fixedly provided with a spring 211, and two sets of first slide grooves 212 are provided inside the connecting sleeve 21. The top surface of the inner cavity of the connecting sleeve 21 is tapped to form a threaded hole 213;

[0035] In this embodiment, the provision of the spring 211 ensures that the extrusion assembly 22 can perform reciprocating linear motion, the first slide groove 212 is used to guide the extrusion assembly 22 during movement, and the threaded hole 213 is used to connect the extrusion assembly 22 .

[0036] Combination Figure 3 and Figure 4 The extrusion assembly 22 includes a fixed rod 221, a threaded rod 222 is formed on the top surface of the fixed rod 221, the threaded rod 222 matches the threaded hole 213, and a rubber sheet 223 is fixedly installed at the lower end of the fixed rod 221;

[0037] In this embodiment, the fixing rod 221 matches the threaded hole 213 inside the connecting sleeve 21 through the threaded rod 222 at its upper end, so as to fix the fixing rod 221 itself to the connecting sleeve 21. The rubber sheet 223 at the lower end of the fixing rod 221 prevents the material at the contact point from deforming when the extrusion component 22 applies pressure to the workpiece 5, thereby facilitating the subsequent recycling component 43 to recycle the cut waste material.

[0038] Combination Figure 4 The outer periphery of the fixing rod 221 is provided with a sleeve 224, the upper end of the sleeve 224 is provided with two sets of sliders 225 matching the first slide groove 212, the lower end of the sleeve 224 is provided with an annular groove 226, and a gasket 227 is bonded inside the annular groove 226;

[0039] In this embodiment, when the extrusion assembly 22 contacts the workpiece 5, the sleeve 224 will rise along the axial direction of the fixed rod 221. During this process, the slider 225 at the upper end of the sleeve 224 will slide in the first slide groove 212, the spring 211 will be compressed, and the rubber sheet 223 at the front end of the fixed rod 221 will contact the workpiece 5 and provide pressure. After the cylinder knife 411 enters the annular groove 226 at the lower end of the sleeve 224, a punching operation is completed. When the pressure plate 1 is lifted upward, the spring 211 rebounds, causing the sleeve 224 to return to its position.

[0040] Combination Figure 4 and Figure 5 The top of the tube knife 411 is polished with a blade 412, and the blade 412 matches the annular groove 226;

[0041] In this embodiment, when the cylindrical knife 411 enters the annular groove 226 at the lower end of the sleeve 224, the blade 412 will contact the gasket 227 to prevent the blade 412 from being damaged during the punching process.

[0042] Combination Figure 6 The recovery assembly 43 includes a material receiving cylinder 431 fixed inside the second mounting seat 42, two sets of racks 432 are arranged inside the material receiving cylinder 431, and a second slide groove 433 is also opened inside the material receiving cylinder 431;

[0043] In this embodiment, as the number of punching times increases, residual materials will continuously enter the material receiving barrel 431, and eventually a cylinder formed by stacking the residual materials will be formed.

[0044] Combination Figure 6 and Figure 7 The recovery assembly 43 also includes a support plate 434, two groups of connecting blocks 435 are fixedly arranged on the outer side of the support plate 434, a torsion spring 436 is installed inside the connecting block 435, a long rod 437 is fixedly arranged on the outer side of the torsion spring 436, and a locking tooth 438 matching the rack 432 and the second slide groove 433 is arranged on the upper end of the long rod 437;

[0045] In this embodiment, the residual material will be stacked on the support plate 434. When the cylinder after the residual material is stacked is at the same height as the receiving barrel 431, as the pressure plate 1 continues to press downward, the support plate 434 will move downward, and the downwardly moved support plate 434 will drive the latching teeth 438 through the long rod 437 to disengage in the gap between the rack 432 in sequence. This is due to the active connection between the torsion spring 436 at the lower end of the long rod 437 and the outer connecting block 435 of the support plate 434. When the latching teeth 438 are located in the gap at the lower end of the rack 432, the residual material can be pushed into the collection box through the existing pushing assembly, and then the support plate 434 can be rotated through the existing rotating and telescopic mechanism and sent back to its original position. During this process, the latching teeth 438 at the upper end of the long rod 437 will slide in the second slide groove 433.

[0046] Combination Figure 1 The pressing plate 1 is fixedly provided with a sliding sleeve 11 at the corner, the base 3 is fixedly provided with a guide column 31 matching the sliding sleeve 11 at the corner, and the surface of the guide column 31 is also provided with a buffer pad 32 located below the second mounting seat 42;

[0047] In this embodiment, the setting of the sliding sleeve 11 can ensure that there will be no jamming when the pressure plate 1 moves downward. The guide column 31 is used to guide the pressure plate 1 to prevent the pressure plate 1 from deviating when moving. The setting of the buffer pad 32 can reduce the impact of the pressure plate 1 on the base 3 when moving downward, thereby increasing its service life.
