[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.
[0018] Embodiment: A miniature dark-punch wedge structure, such as Figure 1-Figure 3 As shown, it includes a lower die base 1, a guide column 11, an upper die base 2, a stripper plate 3, a driving block 4 and a workpiece body 5. A plurality of guide columns 11 are symmetrically installed on the top of the lower die base 1 by bolts, and the upper die base 2 is slidably connected to the guide columns 11. A stripper plate 3 is installed on the top of the lower die base 1, and a driving block 4 is installed on the upper die base 2. A workpiece 5 is placed between the stripper plate 3 and the lower die base 1. The central axis of the guide pressing block 62 is perpendicular to the plane of the inclined panel to be processed of the workpiece body 5. It also includes an inclined wedge assembly 6. An inclined wedge assembly 6 for inclined wedge punching is arranged in the middle of the top of the lower die base 1.
[0019] like Figure 1 and Figure 3 As shown, the wedge assembly 6 includes a guide press block 62, a mounting block 61, a stamping clamp 63, a punch 64, a nitrogen spring 65 and a slider 66. The mounting block 61 is mounted on the lower die base 1, and the mounting block 61 is mounted on the lower die base 1 by bolts. The guide press block 62 is welded on the mounting block 61. The guide press block 62 is a steel cylinder with a round hole at the bottom. The lower end of the nitrogen spring 65 is fixedly connected to the bottom plate of the cylinder of the guide press block 62. The punch 64 can A guide press block 62 extends downward through the circular hole, and the central axis of the guide press block 62 is set at an angle of 80 degrees to the horizontal. A stamping clamp 63 is slidably connected in the guide press block 62, and a punch 64 and a nitrogen spring 65 are fixed on the stamping clamp 63. A slider 66 is slidably connected to the upper part of the guide press block 62. The bottom of the driving block 4 can fit with the top of the slider 66, and the driving block 4 provides power to push the slider 66 to slide downward in the guide press block 62.
[0020] When this embodiment is applied, the stripping plate 3 presses and fixes the workpiece body 5, and then the upper die seat 2 is pressed downward to drive the driving block 4 to fit with the top of the slider 66. At this time, the driving block 4 starts and pushes the slider 66 to slide downward along the guide pressing block 62, thereby pushing the clamping plate 63 to move downward. At this time, the nitrogen spring 65 is compressed, and the punch 64 follows the clamping plate 63 to extend downward from the guide pressing block 62 and punch the workpiece body 5. After the punching is completed, the driving block 4 is reset, thereby releasing the squeezing of the slider 66. Under the reset action of the nitrogen spring 65, the clamping plate 63 drives the punch 64 to reset upward, and the slider 66 is also pushed upward and reset by the clamping plate 63. At this point, the oblique wedge punching processing of the workpiece body 5 is completed. This structure changes the structural style of the traditional oblique wedge, has a simple structure, occupies a small space, and is suitable for oblique wedge punching processing of smaller workpieces.
[0021] like Figure 1 and Figure 3 As shown, it also includes a limiting bolt 7, and the limiting bolt 7 is arranged on the side wall of the guide pressing block 62.
[0022] The setting of the limiting bolt 7 can prevent the sliding block 66 from being separated from the guide pressing block 62 due to the inertia of returning upward.
