Description

Technical Field

[0001] This utility model relates to the field of punching die technology, and in particular to a punching die punch adjustment structure. Background Technology

[0002] Currently, the roughing die is directly embedded in the upper and lower clamping plates of the die set, and the cutting is controlled by a pressure plate holding the die in place. During the punching process, the high-speed punching can easily cause the die to break at the clamping plate, requiring a new die to be manufactured for replacement. However, since the die is directly embedded in the upper and lower clamping plates of the die set, replacing the die requires removing the roughing die from the machine, resulting in downtime for repairs and wasted labor time.

[0003] In existing equipment, the punches of traditional punching dies are usually installed by directly embedding them in the upper and lower clamping plates of the die frame and fixing them with pressure plates. When replacing them, the entire roughing die must be disassembled and removed from the machine. This not only leads to production stoppage but also causes a large waste of manpower and significantly increases production costs and maintenance difficulty. Therefore, we propose a punching die adjustment structure to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a punching die adjustment structure that can effectively solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A punching die adjusting structure includes a power component, a placement component mounted on the upper part of the power component, a pressing component mounted on the lower part of the power component, a sliding component slidably connected to the upper part of the power component, a replacement component installed in the inner cavity of the sliding component, and a fixing component slidably connected to the inner surface of the pressing component.

[0007] Preferably, the power assembly includes a base plate, a support frame is fixedly connected to the upper end of the base plate, and a cylinder is installed on the upper end of the support frame.

[0008] Preferably, the placement component includes a placement block, which is mounted on the upper end of the base plate, and a recycling trough is installed at both the left and right ends of the placement block.

[0009] Preferably, the compression assembly includes a connecting plate, which is installed at the cylinder output end. Two guide rods are fixedly connected to the upper end of the connecting plate, a limit block is fixedly connected to the lower end of the connecting plate, and two wedge blocks are fixedly connected to the lower end of the connecting plate.

[0010] Preferably, the sliding assembly includes two sliding wedge blocks, the lower ends of which are slidably connected to the upper end of the base plate, two springs are installed at the ends of the two sliding wedge blocks that are close to each other, two sliding rods are installed at the ends of the two sliding wedge blocks that are close to each other, and two contact blocks are installed at the ends of the four springs that are close to the center.

[0011] Preferably, the replacement component includes cutting tools, the lower ends of the two cutting tools are slidably connected to the bottom wall of the inner cavity of the two sliding wedge blocks respectively, the lower ends of the two cutting tools are fixedly connected to two T-blocks, and the inner surfaces of the two cutting tools are threaded with two bolts.

[0012] Preferably, the fixing component includes two sliding rods, the outer surfaces of which are slidably connected to the inner surface of the connecting plate, and two springs are fixedly connected to the lower end of the connecting plate. The lower ends of the two sliding rods and the lower ends of the two springs are jointly fixedly connected to a clamping block.

[0013] Preferably, the outer surfaces of the two springs located in the same part are slidably connected to the inner surface of the contact block located in the same part, and the outer surfaces of the two bolts located in the same part are slidably connected to the inner surface of the sliding wedge block located in the same part.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This device can fix the workpiece before die cutting by designing a power component, a placement component, a pressing component, and a fixing component. The clamping block clamps the workpiece to fix it, thereby ensuring that the relative position between the punch and the workpiece is always accurate, making the dimensions of the finished product more accurate. At the same time, the impact force of die cutting can easily cause the workpiece to vibrate slightly, resulting in burrs, cracks, or rough cross-sections. By clamping to suppress vibration, the roughness of the cut can be reduced, thereby improving the surface quality.

[0016] 2. This device enables quick tool replacement through its designed sliding and replacement components. Traditionally, tools are fixed to the device, and when a tool is damaged, the entire component needs to be replaced, which is too costly. This device only requires unscrewing the bolts and sliding the tool out to achieve quick tool replacement. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1, as Figure 1 As shown, a punching die adjusting structure includes a power component 1, a placement component 2 mounted on the upper part of the power component 1, a pressing component 3 mounted on the lower part of the power component 1, a sliding component 4 slidably connected to the upper part of the power component 1, a replacement component 5 installed in the inner cavity of the sliding component 4, and a fixing component 6 slidably connected to the inner surface of the pressing component 3.

[0025] When implementing this solution, the operator first places the workpiece on the placement component 2, and then the operator activates the power component 1 to lower the pressure component 3 and the fixing component 6, so that the fixing component 6 clamps the workpiece to prevent the workpiece from shaking during die cutting, which would result in the cut workpiece having burrs, cracks and other phenomena.

[0026] At the same time, when the pressing component 3 slides down, the pressing component 3 will press the sliding component 4, which will cause the sliding component 4 to drive the changing component 5 to move laterally, so that the changing component 5 can perform die cutting on the workpiece.

[0027] When it is necessary to change the tool, the operator first unscrews the bolt 53 with a tool, and then the operator can let the tool 51 and the T-block 52 slide out in the inner cavity of the sliding wedge block 41, thereby removing the tool 51 and achieving the effect of quickly changing the tool 51.

[0028] Specifically, in order to clamp the workpiece, such as Figure 2As shown, in this scheme, the power assembly 1 includes a base plate 11, a support frame 12 is fixedly connected to the upper end of the base plate 11, and a cylinder 13 is installed on the upper end of the support frame 12.

[0029] For further details, please refer to [link / reference]. Figure 3 The placement component 2 includes a placement block 21, which is installed on the upper end of the base plate 11. A recycling trough 22 is installed on both the left and right ends of the placement block 21.

[0030] For further details, please refer to [link / reference]. Figure 4 The compression assembly 3 includes a connecting plate 31, which is installed at the output end of the cylinder 13. Two guide rods 32 are fixedly connected to the upper end of the connecting plate 31, a limit block 33 is fixedly connected to the lower end of the connecting plate 31, and two wedge blocks 34 are fixedly connected to the lower end of the connecting plate 31.

[0031] For further details, please refer to [link / reference]. Figure 4 The fixing component 6 includes two sliding rods 61. The outer surfaces of the two sliding rods 61 are slidably connected to the inner surface of the connecting plate 31. Two springs 62 are fixedly connected to the lower end of the connecting plate 31. The lower ends of the two sliding rods 61 and the lower ends of the two springs 62 are fixedly connected to a clamping block 63.

[0032] When implementing this solution, the operator first places the workpiece on the placement block 21, and then the operator activates the cylinder 13 to lower the connecting plate 31, guide rod 32, limit block 33, wedge block 34, sliding rod 61, spring 62 and clamping block 63, so that the clamping block 63 clamps the workpiece to prevent the workpiece from shaking during die cutting, which would result in burrs, cracks and other phenomena in the cut workpiece.

[0033] Example 2: This example involves die-cutting the workpiece based on Example 1.

[0034] Specifically, in order to die-cut the workpiece, such as Figure 5 As shown, in this scheme, the sliding component 4 includes two sliding wedge blocks 41. The lower ends of the two sliding wedge blocks 41 are slidably connected to the upper end of the base plate 11. Two springs 42 are installed at the ends of the two sliding wedge blocks 41 that are close to each other. Two sliding rods 43 are installed at the ends of the two sliding wedge blocks 41 that are close to each other. Two contact blocks 44 are installed at the ends of the four springs 42 that are close to the center.

[0035] For further details, please refer to [link / reference]. Figure 5 The replacement component 5 includes a cutting tool 51. The lower ends of the two cutting tools 51 are slidably connected to the bottom wall of the inner cavity of the two sliding wedge blocks 41, respectively. The lower ends of the two cutting tools 51 are fixedly connected to two T-blocks 52, and the inner surfaces of the two cutting tools 51 are threaded with two bolts 53.

[0036] For further details, please refer to [link / reference]. Figure 5The outer surfaces of the two springs 42 located in the same part are slidably connected to the inner surface of the contact block 44 located in the same part, and the outer surfaces of the two bolts 53 located in the same part are slidably connected to the inner surface of the sliding wedge block 41 located in the same part.

[0037] When this solution is implemented, as the clamping block 63 slides down, the wedge block 34 will press the sliding wedge block 41, which will cause the sliding wedge block 41 to drive the spring 42, the sliding rod 43, the contact block 44 and the cutter 51 to move laterally, so that the cutter 51 can perform die cutting on the workpiece.

[0038] At the same time, when the clamping block 63 is pressed down, the second spring 62 will contract, thereby allowing the clamping block 63 to buffer when clamping the workpiece, avoiding damage to the workpiece. When the second sliding wedge block 41 slides, the contact block 44 will contact the placement block 21 first. At this time, the first spring 42 will contract, thereby preventing the tool 51 from directly contacting the tool and causing damage to the tool 51.

[0039] Furthermore, after the workpiece is die-cut by the cutting tool 51, the recycling tank 22 will catch the waste material of the workpiece, thereby preventing the waste material from being piled up randomly.

[0040] When it is necessary to change the tool, the operator first unscrews the bolt 53 with a tool, and then the operator can let the tool 51 and the T-block 52 slide out in the inner cavity of the sliding wedge block 41, thereby removing the tool 51 and achieving the effect of quickly changing the tool 51.

[0041] In summary, the implementation process of this utility model is as follows:

[0042] The operator first places the workpiece on the placement block 21, and then the operator starts the cylinder 13 to lower the connecting plate 31, guide rod 32, limit block 33, wedge block 1 34, sliding rod 2 61, spring 2 62 and clamping block 63, so that the clamping block 63 clamps the workpiece to prevent the workpiece from shaking during die cutting, which would result in the cut workpiece having burrs, cracks and other phenomena.

[0043] At the same time, when the clamping block 63 slides down, the wedge block 34 will press the sliding wedge block 41, which will cause the sliding wedge block 41 to drive the spring 42, the sliding rod 43, the contact block 44 and the cutter 51 to move laterally, so that the cutter 51 can perform die cutting on the workpiece.

[0044] At the same time, when the clamping block 63 is pressed down, the second spring 62 will contract, thereby allowing the clamping block 63 to buffer when clamping the workpiece, avoiding damage to the workpiece. When the second sliding wedge block 41 slides, the contact block 44 will contact the placement block 21 first. At this time, the first spring 42 will contract, thereby preventing the tool 51 from directly contacting the tool and causing damage to the tool 51.

[0045] When it is necessary to change the tool, the operator first unscrews the bolt 53 with a tool, and then the operator can let the tool 51 and the T-block 52 slide out in the inner cavity of the sliding wedge block 41, thereby removing the tool 51 and achieving the effect of quickly changing the tool 51.

[0046] It should be noted that the specific installation method, circuit connection method, and control method of the cylinder 13 and other components used in this utility model are all conventional designs, and will not be described in detail in this utility model.
