Abstract
Description

[0002] Hardware parts are mainly mass-produced through casting methods, such as wax casting. Figure 7 The figure shows a hardware part 20 cast by wax mold. Since the two side planes 21 are suspended, the two side planes 21 are prone to shrinking inward during the casting process, which causes deformation of both side planes and top plane 22. Therefore, after casting is completed, a shaping process is required to flatten the two side planes.

Furthermore, leveling the two side planes 21 and the top plane 22 separately can easily cause the previously leveled structure to deform again in subsequent leveling processes, resulting in poor overall leveling quality of the hardware 20. Therefore, in order to solve this problem… Figure 1 The hardware component 20 shown is similar to other workpieces that require simultaneous leveling of the side and top surfaces. These workpieces have technical problems such as multiple leveling processes and poor leveling quality. Therefore, the hardware component shaping structure proposed in this application is proposed.

[0029] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.
[0030] like Figures 1 to 3 As shown, a hardware forming structure 10 is used for mounting on a punch press. It includes a base 100 and a forming assembly 200. A vertical groove 110 is formed within the base 100. The forming assembly 200 includes a sliding core 210, an elastic element 220, and a pressure head 230. The sliding core 210 is slidably disposed within the groove 110. A material-carrying portion 240 is provided at the top of the sliding core 210. The elastic element 220 is disposed within the groove 110 and abuts against both the sliding core 210 and the base 100. The elastic element 220 is used for pushing. The sliding core 210 allows the material-carrying part 240 to extend from the top surface of the base 100. The bottom surface of the pressure head 230 is provided with a pressure groove. When the pressure head 230 approaches the base 100, it is used to clamp the hardware 20 together with the pressure groove and the material-carrying part 240, so that the hardware 20 slides into the sliding groove 110 synchronously with the sliding core 210. This allows the outer side wall of the material-carrying part 240 and the inner side wall of the sliding groove 110 to jointly press and clamp the side plane 21 of the hardware 20, and the inner side wall of the pressure groove and the outer top wall of the material-carrying part 240 to jointly press and clamp the top plane 22 of the hardware 20.
[0031] It should be noted that in the initial state, the base 100 is fixed at the corresponding position on the punch press, and the pressure head 230 is mounted on the power arm of the punch press, with the pressure head 230 positioned above the base 100. The elastic element 220 abuts against both the sliding core 210 and the base 100. Under the pushing action of the elastic element 220, the sliding core 210 slides upward within the sliding groove 110, causing the material-carrying part 240 at the top of the sliding core 210 to extend from the top surface of the base 100. At this time, the operator can place the metal part 20 to be shaped onto the material-carrying part 240. During the shaping process, the punch press drives the pressure head 230 closer to the base 100. As the pressure head 230 moves downward, the pressure groove on the bottom surface of the pressure head 230 and the material-carrying part 240 together clamp the metal part 20, wherein the shape of the pressure groove is adapted to the top surface of the metal part 20. As the pressure head 230 continuously applies downward pressure, the hardware part 20 drives the sliding core 210 to overcome the elastic force of the elastic element 220 and simultaneously slide into the slide groove 110. During the sliding process, the outer wall of the material-carrying part 240 and the inner wall of the slide groove 110 cooperate to clamp the side plane 21 of the hardware part 20; at the same time, the inner wall of the groove and the outer top wall of the material-carrying part 240 cooperate to clamp the top plane 22 of the hardware part 20. Through this synchronous multi-plane clamping action, the hardware part 20 is shaped. In the reset state, when the pressure head 230 completes the shaping action and lifts upward, no longer applying pressure to the hardware part 20, the elastic element 220 restores its elastic deformation, pushing the sliding core 210 to slide upward, so that the material-carrying part 240 extends out from the top surface of the base 100 again. At this time, the shaped hardware part 20 can be taken out to prepare for the next shaping operation. Thus, by having the outer wall of the loading section 240 and the inner wall of the slide groove 110 jointly clamp the side plane 21 of the hardware part 20, and by having the inner wall of the pressing groove and the outer top wall of the loading section 240 jointly clamp the top plane 22 of the hardware part 20, simultaneous and precise clamping of multiple planes of the hardware part 20 is achieved. This effectively ensures the positional and shape accuracy of the hardware part during the forming process, reduces forming errors, and improves the forming quality of the hardware part. Secondly, the operation is simple. The working process of this forming structure mainly relies on the punch press driving the pressing head 230 to move up and down. The operator only needs to place the hardware part 20 to be formed on the loading section 240 and start the punch press to complete the forming operation. The whole process is simple and easy to understand, reducing the technical requirements and labor intensity of the operator and improving production efficiency. Moreover, the structure is stable and reliable. The setting of the elastic element 220 ensures that the sliding core 210 has good reset performance in the slide groove 110, ensuring the consistency and stability of each forming operation. Meanwhile, the sliding core 210 is adapted to slide within the sliding groove 110, which effectively prevents the sliding core 210 from shaking or shifting during sliding, further improving the reliability of the shaping structure. Thus, the hardware shaping structure 10 of this application can be applied to perform one-time leveling of workpieces similar to the hardware 20 that require simultaneous leveling of the side and top surfaces.
[0032] As shown in Figure 4 and Figure 5 shown, in an embodiment, the inner side wall of the sliding groove 110 is provided with a positioning groove 120 along the axial direction, and the outer side wall of the sliding core 210 is provided with a positioning protrusion 250 along the axial direction, and the positioning protrusion 250 is slidingly arranged in the positioning groove 120.
[0033] It should be noted that the positioning protrusion 250 is embedded in the positioning groove 120, which ensures that the sliding core 210 can only slide along the axial direction of the positioning groove 120, and realizes accurate guidance during the shaping process and the resetting process of the sliding core 210.
[0034] In an embodiment, two positioning grooves 120 are provided, and two positioning protrusions 250 are provided, and the two positioning protrusions 250 are slidingly arranged in the two positioning grooves 120, respectively. In this way, the two positioning protrusions 250 are located on the opposite sides of the sliding core 210, which can improve the stability of the sliding core 210 sliding in the sliding groove 110.
[0035] As shown in Figure 3 , in an embodiment, a top core 300 is arranged in the base 100, the top core 300 is located in the sliding groove 110, and one end of the top core 300 penetrates the sliding core 210.
[0036] It should be noted that the top core 300 is fixedly installed in the base 100, and the top core 300 penetrates the sliding core 210, so that the sliding stability of the sliding core 210 in the sliding groove 110 can be improved.
[0037] As shown in Figure 6 , in an embodiment, a top block 260 is slidingly arranged in the sliding core 210 in the transverse direction, and when the pressing head 230 pushes the top block 260 to descend, the top core 300 holds the top block 260 to extend from one side of the loading part 240.
[0038] It should be noted that the hardware 20 is placed on the loading part 240, so that the hardware 20 is pressed by the pressing head 230 to slide into the sliding groove 110 along with the sliding core 210. Therefore, the gap between the loading part 240 and the inner side wall of the sliding groove 110 must be greater than the thickness of the side plane 21 of the hardware 20, that is, there must be a gap between the hardware 20 and the outer side wall of the loading part 240 and the inner side wall of the sliding groove 110. If the gap is too large, the flattening quality of the hardware 20 will be reduced, so in order to eliminate this gap and improve the flattening effect of the side plane 21 of the hardware 20, the top block 260 is slidingly arranged in the loading part 240 in the transverse direction. In this way, when the sliding core 210 slides downward along the sliding groove 110, the top core 300 is inserted into the sliding core 210, so that the top core 300 holds the top block 260, and the top block 260 extends from the outer side wall of the loading part 240 to press the inner wall surface of the side plane 21 of the hardware 20.
[0039] In an embodiment, the elastic member 220 is a coil spring, which is sleeved outside the top core 300. In this way, the elastic member 220 can reliably push the top sliding core 210, so that the loading part 240 is stably extended from the surface of the base 100.
[0040] As shown in Figure 6 In an embodiment, the top of the top core 300 is provided with a first inclined surface 310, and the top block 260 is provided with a second inclined surface 261, and the first inclined surface 310 is used to adaptively hold the second inclined surface 261.
[0041] It should be noted that the first inclined surface 310 and the second inclined surface 261 are adaptively inclined surface structures, the top core 300 vertically slides relative to the sliding core 210, and the top block 260 transversely slides relative to the sliding core 210, so that under the action of the component forces of the first inclined surface 310 and the second inclined surface 261, the top core 300 can reliably push the top block 260 to extend from the outer side wall of the loading part 240.
[0042] In an embodiment, two top blocks 260 are provided, and the two top blocks 260 are respectively located on the two sides of the top core 300. In this way, the single top core 300 is used to simultaneously push the two top blocks 260 to extend from the two oppositely distributed outer side walls of the loading part 240, so as to respectively push the two side planes 21 of the hardware 20 and simultaneously level the two side planes 21 of the hardware 20.
[0043] As shown in Figure 6 In an embodiment, the sliding core 210 is further provided with a return spring 270, the return spring 270 abuts against the top block 260 and the sliding core 210, and the return spring 270 is used to press the top block 260, so that the top block 260 is retracted into the sliding core 210.
[0044] It should be noted that when the top core 300 does not press the top block 260, the top block 260 is pressed by the return spring 270, so that the top block 260 is retracted into the loading part 240, thereby ensuring that the hardware 20 is smoothly taken and placed on the loading part 240.
[0045] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent. In the present application, the installation / fixation / setting can be understood as including but not limited to locking and fixing by screws, welding, unless otherwise defined. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
