Description
Technical Field
[0001] This utility model relates to the field of hinge processing equipment technology, and in particular to hinge punching mold. Background Technology
[0002] The side of the slotted hinge seat has a side hole to facilitate the connection of the hinge seat with other structures by fitting a pin, bolt or bolt and other connecting parts.
[0003] When punching the aforementioned side holes, the punch arbitrates the hinge seat from the outside. To prevent deformation of the hinge seat during punching, a support block needs to be installed in the mounting groove of the hinge seat, which complicates the punching equipment and the clamping steps of the hinge seat during punching, reducing the processing efficiency of the hinge seat. Furthermore, punching the side holes from the outside to the inside will generate burrs at the opening of the side holes on the inner side of the hinge seat. These burrs are located on the inner side of the hinge seat, making them inconvenient to grind, further reducing the processing efficiency of the hinge seat.
[0004] 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
[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a hinge punching die to improve the processing efficiency of hinge seats.
[0006] The technical solution of this utility model is as follows: The hinge punching die includes a base and a pressure block arranged facing each other. The side of the base near the pressure block supports the hinge seat. The mounting groove of the hinge seat faces the pressure block. A fixing plate is provided on the pressure block. The fixing plate extends into the mounting groove, and a punch is provided on the fixing plate. The outer diameter of the punch corresponds to the diameter of the hole to be machined in the hinge seat, and the punch is aligned with the hole to be machined and arranged along the axis of the hole to be machined.
[0007] A further technical solution involves providing a telescopic assembly and a positioning rod on the base. The positioning rod passes through mounting holes at both ends of the hinge seat along its length. The positioning rod connects to the movable end of the telescopic assembly.
[0008] A further technical solution involves providing a telescopic cavity on the base. The telescopic component is housed within the telescopic cavity.
[0009] A further technical solution involves providing a limiting block on the base. An extension is provided on the limiting block, perpendicular to the axis of the hole to be machined, forming a limiting groove between the extension and the base. The hinge seat extends into the limiting groove.
[0010] A further technical solution involves aligning the extension portion with the mounting hole. An axial extension guide hole is provided on the extension portion to guide the positioning rod.
[0011] A further technical solution involves a pressure plate located on the side of the pressure block furthest from the base. The pressure plate connects to the pressure block. A guide rod is mounted on the pressure plate along the axial direction of the hole to be machined. A guide sleeve is mounted on the base for the guide rod to extend into.
[0012] A further technical solution is that at least two guide sleeves and guide rods are evenly arranged around the pressure block.
[0013] A further technical solution involves providing a reset rod on the base. A reset hole is formed on the pressure plate for the reset rod to pass through. An elastic element is fitted onto the reset rod. The elastic element contacts the surface of the pressure plate near the base.
[0014] A further technical solution involves providing a pad on the base. The hinge seat is mounted on the pad. The surface of the pad corresponds to the surface of the hinge seat.
[0015] A further technical solution is to surround the pressure block, and two punches can be set on the opposite side of the pressure block.
[0016] The beneficial technical effects of this utility model are as follows: (1) In the hinge punching die of this utility model, the punch is set inside the hinge seat. When punching the hole to be processed, the punch punches the side hole from the assembly groove to the outside of the hinge seat. After the side hole is processed, the burr at the opening of the side hole is formed on the outer surface of the hinge seat. The burr is easy to grind, which facilitates the subsequent processing of the hinge seat and improves the processing efficiency of the hinge seat. Moreover, the hinge seat is set on the base, and the base and the fixing plate are set on the opposite side of the hole to be processed to clamp and support the hinge seat. When the punch punches the hinge seat, there is no need to set an additional support structure to support the hinge seat, which simplifies the structure of the hinge punching die, thereby simplifying the clamping steps of the hinge seat and further improving the processing efficiency of the hinge seat.
[0017] (2) Furthermore, the base is also provided with a positioning rod and a limiting block to fix the hinge seat on the base in the axial direction, so as to ensure the stability of the hinge seat during punching.
[0018] (3) Furthermore, a guide sleeve, a guide rod, and an elastic element are provided. The guide sleeve and guide rod work together to ensure that the punch moves along a preset path, ensuring the machining accuracy of the hole to be processed. After punching is completed, the elastic element can push the punch back along the guide rod, simplifying the operation steps of the hinge punching die. Attached Figure Description

[0025] Figure 1 A perspective view of a hinge punching die according to an embodiment of the present disclosure is shown. Figure 2 A schematic diagram of the internal structure of a hinge punching die according to an embodiment of the present disclosure is shown. Figure 3 A three-dimensional structural schematic diagram of a hinge seat in a hinge punching die according to an embodiment of this disclosure is shown. Please refer to... Figure 1 , Figure 2 and Figure 3The hinge punching die includes a base 1 and a pressure block 3 facing each other. The base 1 supports a hinge seat 6 on the side near the pressure block 3. The mounting groove 61 of the hinge seat 6 faces the pressure block 3. A fixing plate 31 is provided on the pressure block 3. The pressure block 3 and the fixing plate 31 can be bolted together. The fixing plate 31 extends into the mounting groove 61, and a punch 32 is provided on the fixing plate 31. The outer diameter of the punch 32 corresponds to the diameter of the hole 62 to be processed in the hinge. The punch 32 is aligned with the hole 62 to be processed and is set along the axis of the hole 62. The punch 32 is located inside the hinge seat 6. When punching the hole 62 to be processed, the punch 32 punches the side hole from the mounting groove 61 to the outside of the hinge seat 6. After the side hole is processed, burrs are formed at the opening of the side hole on the outer surface of the hinge seat 6. The burrs are easy to grind, which facilitates the subsequent processing of the hinge seat 6 and improves the processing efficiency of the hinge seat 6. Furthermore, the hinge seat 6 is mounted on the base 1, and the base 1 and the fixing plate 31 are positioned on the opposite side of the hole 62 to be processed to clamp and support the hinge seat 6. When the punch 32 punches the hinge seat 6, there is no need to set up an additional support structure to support the hinge seat 6, which simplifies the structure of the hinge punching die, thereby simplifying the clamping steps of the hinge seat 6 and further improving the processing efficiency of the hinge seat 6.
[0026] In some embodiments, two punches 32 can be provided on the opposite side of the pressure block 3. Correspondingly, two hinge seats 6 can be provided on the base 1. When the pressure block 3 moves to perform punching, the two punches 32 respectively process the holes 62 to be processed on the two hinge seats 6, further improving the processing efficiency of the hinge seats 6.
[0027] Please refer to Figure 1 and Figure 2 The base 1 is also provided with a telescopic assembly 11 and a positioning rod 13. The mounting holes 63 at both ends of the positioning rod 13 along the length of the hinge seat 6 pass through the hinge seat 6. The positioning rod 13 is connected to the movable end of the telescopic assembly 11. Driving the movable end of the telescopic assembly 11 to extend or retract can move the positioning rod 13 through the mounting holes 63 to limit the hinge seat 6, or move the positioning rod 13 away from the hinge seat 6. In some embodiments, the telescopic assembly 11 can be a cylinder. The cylinder body is fixed to the base 1, and the piston rod of the cylinder is connected to the positioning rod 13.
[0028] Preferably, the base 1 has a telescopic cavity 12. The telescopic component 11 is disposed inside the telescopic cavity 12 and is surrounded and protected by the base 1.
[0029] Please refer to Figure 1 and Figure 2 A limiting block 21 is also provided on the base 1. An extension 22 is provided on the limiting block 21 perpendicular to the axis of the hole 62 to be processed, and a limiting groove 23 is formed between the extension 22 and the base 1. The hinge seat 6 extends into the limiting groove 23 and is limited, further fixing the hinge seat 6 on the base 1 and improving the stability of the hinge seat 6 during punching.
[0030] Preferably, the extension 22 is aligned with the mounting hole 63. An obstruction guide hole 221 is provided on the extension 22 along the axial direction of the positioning rod 13. The obstruction guide hole 221 prevents interference between the positioning rod 13 and the extension 22, while also serving a guiding function to guide the positioning rod 13 to extend and retract in a preset direction.
[0031] More preferably, a pad 2 is also provided on the base 1. The hinge seat 6 is disposed on the pad 2. The surface of the pad 2 corresponds to the surface of the hinge seat 6 to fit the pad 2 and the hinge seat 6, thereby improving the stability of the hinge seat 6. A limiting block 21 may be disposed on the pad 2.
[0032] Please refer to Figure 1 and Figure 2 A pressure plate 4 is provided on the side of the pressure block 3 away from the base 1. The pressure plate 4 is connected to the pressure block 3. A guide rod 41 is provided on the pressure plate 4 along the axial direction of the hole 62 to be processed. A guide sleeve 14 is provided on the base 1 for the guide rod 41 to extend into. The guide sleeve 14 and the guide rod 41 cooperate to ensure that the punch 32 moves along a preset path, ensuring the processing accuracy of the hole 62 to be processed.
[0033] Preferably, at least two guide sleeves 14 and guide rods 41 are evenly arranged around the pressure block 3. This avoids the relative rotation of the guide sleeve 14 and guide rod 41 when a single guide sleeve 14 and guide rod 41 are engaged, which would affect the fitting accuracy between the base 1 and the pressure block 3. The engagement of multiple guide sleeves 14 and guide rods 41 can also distribute the force and increase the overall load between the guide sleeves 14 and guide rods 41.
[0034] More preferably, a reset rod 5 is also provided on the base 1. A reset hole 42 is provided on the pressure plate 4 for the reset rod 5 to pass through. An elastic element (not shown in the figure) is sleeved on the reset rod 5. The elastic element can be a spring. The elastic element contacts the surface of the pressure plate 4 near the base 1. When the pressure plate 4 moves downward to punch the hinge seat 6, the reset rod 5 passes through the pressure plate 4, and the elastic element is compressed by the pressure plate 4. After punching is completed, the elastic element can push the punch 32 to reset along the guide rod 41, eliminating the need for additional operation by the operator and simplifying the operation steps of the hinge punching film.
[0035] The specific workflow of this utility model is as follows: The operator moves the hinge seat 6 into the limiting groove 23 and allows the fixing plate 31 to extend into the assembly groove 61, aligning the punch 32 and the hole to be processed 62. The telescopic assembly 11 is activated, and its movable end extends to push the positioning rod 13 until it passes through the hinge seat 6 along the mounting hole 63 and extends into the clearance guide groove. The punching drive mechanism (not shown) pushes the pressure plate 4 towards the base 1. The pressure plate 4 descends, causing the pressure block 3, fixing plate 31, and punch 32 to descend, punching the hole to be processed 62 on the hinge seat 6. During the punching process, the elastic element between the pressure plate 4 and the base 1 is compressed. After punching, the elastic element resets, pushing the pressure plate 4 upwards. The upward movement of the pressure plate 4 causes the pressure block 3, fixing plate 31, and punch 32 to move upwards. The punch 32 moves out of the processed hole. The telescopic assembly 11 is driven, and its movable end retracts, pulling the positioning rod 13 until it is completely disengaged from the hinge seat 6. At this point, the hinge seat 6 is finished being punched and can be removed from the pad 2.
[0036] 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.
[0037] 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.
