Description

Technical Field

[0001] This utility model relates to the field of hole-flipping equipment technology, and in particular to hole-flipping devices. Background Technology

[0002] The main structural members of a car's crossbeam are responsible for load-bearing and connection, and holes need to be drilled for these connections.

[0003] The flange of a flanged hole can create a "thickened area" at the hole edge, enhancing the structural strength of the hole edge. The flange can also act as a guide structure and increase the contact area between the automotive crossbeam frame and the threaded fasteners. Furthermore, flanging is simple to manufacture and can be quickly processed using stamping techniques.

[0004] However, during stamping and flanging, the flanges of the flanged holes can hinder workpiece removal, especially when there are two opposing flanged holes on the workpiece. If a support structure with holes is desired to adequately support the workpiece during processing, the two opposing flanged holes must be processed in batches to prevent the workpiece from getting stuck on the support structure and becoming unremovable. Batch processing reduces the processing efficiency of automotive crossbeam frame components and increases workpiece costs.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a hole-flipping device to improve the efficiency of workpiece hole-flipping processing.

[0007] The technical solution of this utility model is as follows: The flipping device includes a slider, a support block, a pressure block, and a punch. The slider is slidably disposed towards the support block. The support block supports the workpiece. The slider slides towards the support block, and the slider and the support block join to form a guide hole. The punch is slidably disposed towards the guide hole. A first inclined surface is provided on the slider, which slopes towards the side near the support block. A second inclined surface is provided on the punch, which slopes towards the side near the guide hole. The pressure block simultaneously contacts both the first and second inclined surfaces.

[0008] A further technical solution is that two punches are provided, and the two punches are located on opposite sides of the workpiece.

[0009] A further technical solution is that a first insert and a second insert are provided on the pressure block. The first insert contacts the first inclined surface. The second insert contacts the second inclined surface.

[0010] A further technical solution is that the second inserter has a protruding outer edge. The surface of the outer edge of the inserter, away from the second inclined surface, is parallel to the second inclined surface. A guide hook is provided on the punch. The guide hook contacts the surface of the outer edge of the inserter away from the second inclined surface.

[0011] A further technical solution includes a base, on which the slider, the support block, and the punch are disposed.

[0012] A further technical solution involves a fixing block on the base. A guide rod is connected to the slider. The guide rod passes through the fixing block. A protruding ring is provided at the end of the guide rod away from the slider. Along the radial direction of the guide rod, the protruding ring protrudes beyond the outer diameter of the guide rod. An elastic element is provided between the protruding ring and the fixing block. The guide rod is arranged parallel to the sliding direction of the slider.

[0013] A further technical solution is that the guide rod, the fixing block, the convex ring, and the elastic element are arranged in pairs on opposite sides of the slider.

[0014] A further technical solution involves providing a first and a second sliding groove on the base. The punch is positioned within the first sliding groove, and the slider is positioned within the second sliding groove.

[0015] A further technical solution involves providing a slide rail within the first groove. The slide rail is slidably connected to the punch.

[0016] A further technical solution is that the pressure block is provided with a slot corresponding to the support block.

[0017] The beneficial technical effects of this utility model are as follows: (1) The flanging device of this utility model is equipped with a punch to process the flanging of the workpiece. A slider and a support block are separately provided. The slider can be connected to form a guide hole by sliding it toward the support block. The workpiece is supported by the slider and the support block. The punch slides toward the guide hole to process the flanging. The flanged edge formed after processing fits the hole wall of the guide hole, and the workpiece is completely fixed on the slider and the support block. At this time, the slider is slid away from the support block, the guide hole is split and the workpiece is no longer fixed by restricting the position of the flanged edge, and the workpiece can be quickly unloaded. The slider and the support block are separately provided, which improves the efficiency of unloading the workpiece after flanging and thus improves the efficiency of workpiece flanging, and reduces the production cost of flanged workpieces. Moreover, the punch and the slider contact the pressure block through the first inclined surface and the second inclined surface respectively, and drive the pressure block to move, which can simultaneously drive the punch and the slider to move, further simplifying the flanging process of the workpiece.

[0018] (2) Further, two punches are provided, and the two punches are located on opposite sides of the workpiece. That is, the downward movement of the pressure block drives the two punches to move, and the two punches simultaneously process the flanges set opposite each other on the two surfaces of the workpiece. In addition, the slider and the support block are set separately. During processing, the guide hole can support the flange. After processing, the workpiece can be directly removed away from the slider and the support block.

[0019] (3) Further, while the second insert contactes the second inclined surface, the outer edge of the second insert is set parallel to the second inclined surface. A guide hook is set on the punch to contact the surface of the outer edge of the insert away from the second inclined surface. When the pressure block drives the second insert downward, the second insert squeezes the second inclined surface and pushes the punch towards the side closer to the support block for processing. When the pressure block moves upward to reset, there is sliding friction between the outer edge of the insert and the guide hook. The outer edge of the insert provides a component force to the guide hook away from the support block to drive the punch to move away from the support block, thereby realizing the automatic reset of the punch and further improving the efficiency of hole turning.

[0027] Figure 1 A schematic diagram of the assembly structure of the punch, slider and pressure block in a hole-flipping device according to an embodiment of the present disclosure is shown. Figure 2 A three-dimensional structural schematic diagram of the pressure block in a hole-flipping device according to an embodiment of the present disclosure is shown. Figure 3 A three-dimensional structural schematic diagram of the workpiece in a flanging device according to an embodiment of this disclosure is shown. Please refer to... Figure 1 , Figure 2 and Figure 3The flanging device includes a slider 3, a support block 61, a pressure block 5, and a punch 1. The slider 3 is slidably positioned towards the support block 61. The support block 61 supports the workpiece 7. The slider 3 slides towards the support block 61, and the slider 3 and the support block 61 are joined to form a guide hole 33. The punch 1 is slidably positioned towards the guide hole 33, and a protruding circle 13 is provided at the end of the punch 1 near the guide hole 33. When the workpiece 7 is supported by the slider 3 and the support block 61, the protruding circle 13 of the punch 1 slides towards the workpiece 7 and penetrates into the guide hole 33, stamping and forming the flanged hole 71. The flange 72 of the flanged hole 71 is supported by the hole wall of the guide hole 33, and the workpiece 7 is completely fixed on the slider 3 and the support block 61. At this time, the slider 3 is slid away from the support block 61, the guide hole 33 is split, and the workpiece 7 is no longer fixed by restricting the position of the flange 72, and the workpiece 7 can be quickly removed. The slider 3 and the support block 61 are separately configured to improve the efficiency of unloading the workpiece 7 after the hole is turned 71, thereby improving the efficiency of turning the workpiece 7 into a hole 71 and reducing the production cost of the workpiece 7. A first inclined surface 12 is provided on the slider 3, which slopes towards the side closer to the support block 61. A second inclined surface 31 is provided on the punch 1, which slopes towards the side closer to the guide hole 33. The pressure block 5 simultaneously contacts the first inclined surface 12 and the second inclined surface 31. Driving the pressure block 5 to move simultaneously drives the punch 1 and the slider 3 to move, further simplifying the turning of the workpiece 7 into a hole 71.

[0028] Preferably, two punches 1 are provided, and the two punches 1 are located on opposite sides of the workpiece 7. That is, the downward movement of the pressure block 5 drives the two punches 1 to move, and the two punches 1 simultaneously process the opposing flanges 71 on the two surfaces of the workpiece 7. In addition, the slider 3 and the support block 61 are separately provided. During processing, the guide hole 33 can support the flange 72. After processing, the workpiece 7 can be directly removed away from the slider 3 and the support block 61.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 A first insert 2 and a second insert 4 are provided on the pressure block 5. The first insert 2 contacts the first inclined surface 12. The second insert 4 contacts the second inclined surface 31. Specifically, the first insert 2 has an inclined surface (not marked in the figure) that contacts the first inclined surface 12, and this inclined surface is parallel to the first inclined surface 12. The second insert 4 has an inclined surface that contacts the second inclined surface 31, and this inclined surface is parallel to the second inclined surface 31.

[0030] Preferably, the second insert 4 has a protruding insert outer edge 21. The surface of the insert outer edge 21 away from the second inclined surface 31 is parallel to the second inclined surface 31. The punch 1 is provided with a guide hook 11. The guide hook 11 contacts the surface of the insert outer edge 21 away from the second inclined surface 31. When the pressure block 5 drives the second insert 4 downward, the second insert 4 presses against the second inclined surface 31, pushing the punch 1 towards the side closer to the support block 61 for processing. When the pressure block 5 moves upward to reset, there is sliding friction between the insert outer edge 21 and the guide hook 11. The insert outer edge 21 provides a component force to the guide hook 11 in a direction away from the support block 61, thereby driving the punch 1 to move away from the support block 61, realizing the automatic reset of the punch 1, and further improving the processing efficiency of the flipping hole 71.

[0031] Figure 4 A schematic diagram of the assembly structure of the base in a flip-hole device according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 4 It also includes a base 6, a slider 3, a support block 61, and a punch 1, all centrally arranged on the base 6. This provides a unified positioning reference and allows for centralized movement after installation, avoiding repeated clamping and adjustment of the positions of various components.

[0032] Preferably, the base 6 has a first groove 62 and a second groove 63. The punch 1 is disposed in the first groove 62. The slider 3 is disposed in the second groove 63. A slide rail 621 is disposed in the first groove 62, and the slide rail 621 slidably connects to the punch 1. There is a clearance fit between the punch 1 and the first groove 62, and between the punch 1 and the slide rail 621. In some embodiments, ball bearing guides may be disposed in the first groove 62 and the second groove 63, and circulating balls may be embedded in the punch 1 and the slider 3 respectively, so as to slidably connect the first groove 62 and the punch 1, and slidably connect the second groove 63 and the slider 3.

[0033] Please refer to Figure 1 , Figure 3 and Figure 4 A fixing block 322 is provided on the base 6. A guide rod 32 is connected to the slider 3. The guide rod 32 passes through the fixing block 322. A protruding ring 321 is provided at the end of the guide rod 32 away from the slider 3. The protruding ring 321 protrudes from the outer diameter of the guide rod 32 along the radial direction of the guide rod 32. The protruding ring 321 and the guide rod 32 can be connected by existing connection methods such as welding or threaded connection. An elastic element 323 is provided between the protruding ring 321 and the fixing block 322. In some embodiments, the elastic element 323 can be a spring. The guide rod 32 is arranged parallel to the sliding direction of the slider 3. When the pressure block 5 presses the slider 3 to move towards the workpiece 7, the elastic element 323 between the protruding ring 321 and the fixing block 322 is compressed. When the pressure block 5 moves upward away from the slider 3, the elastic element 323 releases its elastic force and returns to its original state, driving the slider 3 to slide away from the workpiece 7, and the slider 3 automatically resets.

[0034] Preferably, the guide rod 32, the fixing block 322, the convex ring 321, and the elastic element 323 are arranged in pairs on opposite sides of the slider 3. The elastic elements 323 are arranged in pairs to balance the elastic force on the slider 3 and enhance the stability of the slider 3 when it returns to its original position.

[0035] More preferably, the pressure block 5 is provided with a slot 51 corresponding to the support block 61. The shapes of the slot 51 and the support block 61 are provided to correspond to the workpiece 7 to enhance the stability of the workpiece 7. When processing the workpiece 7, the pressure block 5 moves down until the inner wall of the slot 51 contacts the workpiece 7. At this time, a cavity (not shown in the figure) is formed between the support block 61 and the slot 51, and the workpiece 7 is fixed in the cavity.

[0036] The specific workflow of this utility model is as follows: When machining the flipped hole 71 on workpiece 7, workpiece 7 is placed on support block 61. A telescopic mechanism (not shown) drives pressure block 5 downwards towards base 6. Pressure block 5 descends along the second inclined plane 31, pressing punch 1, and simultaneously pressing slider 3 along the first inclined plane 12. Slider 3 is pressed towards support block 61 until it contacts support block 61, forming guide hole 33. During this process, elastic element 323 is compressed. Punch 1 is pressed towards guide hole 33 until it punches workpiece 7 along guide hole 33, forming flipped hole 71. Then pressure block 5 moves upwards. First insert 2 no longer contacts slider 3, elastic element 323 returns to its original position, driving slider 3 to reset, and guide hole 33 is opened. Simultaneously, second insert 4 moves upwards, with sliding friction between insert outer edge 21 and guide hook 11. Insert outer edge 21 provides guide hook 11 with a component force away from support block 61, driving punch 1 to move away from support block 61, and punch 1 resets. At this point, workpiece 7 can be removed, and the drilling of hole 71 on workpiece 7 can be completed.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
