DETAILED DESCRIPTION

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0030] See also Figure 1The high-precision metal stamping die structure in this embodiment includes a bottom plate 100, and a guide column 101 is symmetrically arranged on the upper surface of the bottom plate 100. The upper end of the guide column 101 is movably sleeved with a top plate 102, and the lower surface of the top plate 102 is equipped with a contact cone 102c. The bottom plate 100 is slidably connected to a slide table 200, and a plurality of second dies 202 are equipped on the slide table 200. The top plate 102 is raised and lowered on the guide column 101 so that the contact cone 102c contacts the second die 202, so that the metal sheet placed on the upper surface of the second die 202 is stamped and formed by extrusion force.

[0031] See also Figure 5 and Figure 6 Schematic diagram of the stamping die structure in this application. In this embodiment, the second die 202 includes a connecting block 202a fixedly mounted on the upper surface of the slide 200. The connecting block 202a is a convex structure. A slide groove is provided in the center of the upper surface of the connecting block 202a. The slide groove runs through the front and rear ends of the connecting block 202a. A slide bar 202b-2 is slidably connected in the slide groove. A cavity plate 202b-1 is also mounted on the upper surface of the connecting block 202a. A mold cavity is provided on the cavity plate 202b-1 and is connected to the slide groove. A protrusion is provided on the upper surface of the slide bar 202b-2, and the protrusion is located at the bottom of the slide groove. In the mold cavity, the hardware that needs to be shaped is placed in the mold cavity. When the slide bar 202b-2 moves in the slide groove, its protrusion performs a stamping action in the mold cavity of the mold cavity plate 202b-1 to achieve the purpose of edge straightening. In the present application, when the top plate 102 moves downward, it drives the resistance cone 102c to move downward synchronously. During the downward movement of the resistance cone 102c, it will resist the slide bar 202b-2, so that the slide bar 202b-2 moves into the mold cavity. During the movement of the slide bar 202b-2 into the mold cavity, the protrusion set on it will The hardware pre-placed in the extrusion mold cavity is pressed to achieve the shaping edge effect; further, in order to enable the contact cone 102c to accurately contact the slide bar 202b-2 during the downward movement, the slide bar 202b-2 needs to have one end protruding outward to facilitate the contact of the contact cone 102c. In the initial state, the slide bar 202b-2 can protrude outward to facilitate the contact of the contact cone 102c. However, after the first stamping is completed, the slide bar 202b-2 will retract into the mold cavity and cannot be restored to its initial position. During the secondary stamping, the abutting cone 102c cannot contact the slide bar 202b-2, so the slide bar 202b-2 needs to be reset after each stamping. Therefore, the upper surface of the connecting block 202a and the upper surface of the slide groove of the present application are both inclined surfaces, and one end of the slide bar 202b-2 protrudes from the lowest end of the inclined surface of the slide groove. A hole is opened on the side of the connecting block 202a, and a spring column 202b-2a is installed in the hole. One end of the spring column 202b-2a abuts against the hole wall, and the other end of the spring column 202b-2a abuts against the inner surface of the protruding end of the slide bar 202b-2.

[0032] See also Figure 3 This is a schematic diagram of the structure of the stamping device in this embodiment. In order to prevent deformation of hardware due to excessive stamping during each stamping process, the degree of stamping needs to be limited to a certain extent. Therefore, this application provides a limit column 100a on the upper surface of the base plate 100 and on one side of the guide column 101, and a stop block 100b is provided at the rear end of the base plate 100. Since the present application uses a sliding slide 200 to allow different molds to be located under the stamping device for stamping, in order to make the sliding of the slide 200 smoother, this embodiment provides a fixed table 100c symmetrically on the upper surface of the base plate 100 and between the guide columns 101, and a track 100c-1 is mounted on the fixed table 100c, and the slide 200 is fixed on the track 100c-1.

[0033] See also Figure 3 and Figure 4 Schematic diagram of the stamping structure in this embodiment. In order to enable the top plate 102 to reset after being lowered, a support tube 101b is movably sleeved on the guide column 101 in this embodiment. Shock-absorbing springs 101a are provided on the guide column 101 and at the upper and lower ends of the support tube 101b. In order to facilitate the lowering of the top plate 102, a driving component needs to be connected. Therefore, a driving connector 102a is provided in the center of the lower surface of the top plate 102 in this embodiment. The upper end of the driving connector 102a penetrates the top plate 102, and the top plate 102 is used to The rebound force of the shock-absorbing spring 101a after being squeezed allows the top plate 102 to be reset to a certain extent and then driven to rise and fall through the driving device. At the same time, in order to enable different hardware parts to be stamped on the device of this application, a punch head 102b is provided on the lower surface of the top plate 102 near the two top corners of the rear end, and a first mold 201 is correspondingly installed on the upper surface of the slide 200 and at the edges on both sides. A plurality of punching holes are opened on the first mold 201 for cooperating with the punch head 102b to complete the stamping.

[0034] In summary: the present application connects the driving component by driving the connecting head 102a, and the driving component causes the top plate 102 to move downward. Before the top plate 102 moves downward, the slide 200 is pushed to move on the track 100c-1, so that the first mold 201 or the second mold 202 on the slide 200 is located directly below the top plate 102. A contact cone 102c is provided on the lower surface of the top plate 102, and the contact cone 102c can contact the second mold 202, so that the second mold 202 completes the stamping of the hardware. At the same time, the top plate 102 descends to directly drive the punching head 102b provided thereon to move downward, and the punching head 102b is inserted into the punching hole on the first mold 201 to complete the stamping process of other hardware structures. The stamping methods in the present application are divided into direct stamping and contact stamping. The direct stamping has a greater force, thereby ensuring that the stamping is completed in one go and is suitable for hardware with thicker plates. The contact stamping belongs to precision stamping, and its stamping force is smaller, and it is mostly used to shape the edges and corners of hardware. Therefore, the present application realizes two different stamping methods through direct stamping and contact stamping, which to a certain extent expands the practicality of the device in the present application. The device in the present application reduces the time for replacing different stamping dies and improves the efficiency of the stamping work to a certain extent. At the same time, since different dies are arranged on the slide, the overall integration of the device in the present application is relatively high, and its scope of use is extended to a certain extent.
