Since the flat workpieces need to be positioned during the forming process, for the bent parts that are not in a symmetrical state, separate forming dies are required. Similarly, for the openings on different bent surfaces, separate punching dies are also required, such as the side punching operation of angle steels with different thicknesses and sizes.

[0003] However, in actual use, the cost of opening holes with separate dies is relatively high. Therefore, it is necessary to fix the workpieces of different sizes to facilitate punching and improve versatility. Therefore, it is required that the stamping device can be easily adjusted and fixed to adapt to the side punching of workpieces of different sizes. Content of the Utility Model

A fixed extrusion plate 401 is installed on one side of the fixed block 4 close to the moving extrusion plate 3. Connecting bolts 403 are installed at both ends of the side of the fixed extrusion plate 401 close to the fixed block 4. A support plate 402 is provided at the top of the fixed block 4. A mounting block 301 is provided on the side of the moving extrusion plate 3 far from the fixed block 4. The mounting block 301 is fixed to the bottom plate 1. A stamping block 302 is provided at the center of the side of the moving extrusion plate 3 close to the fixed block 4.

[0026] As shown in Figure 1 , Figure 3As shown in the figure, extrusion push rods 303 are installed at both ends of the side of the moving extrusion plate 3 away from the fixed block 4 and at the inner center of the installation block 301. The inner extended end of the extrusion push rod 303 at the center of the installation block 301 is fixed to the stamping block 302. The outer wall of the extrusion push rod 303 at both ends of the moving extrusion plate 3 is fixed to the installation block 301. The inner extended ends of the extrusion push rods 303 at both ends of the moving extrusion plate 3 are fixed to the moving extrusion plate 3. A through hole corresponding to the stamping block 302 is provided at the inner center of the moving extrusion plate 3. By starting the extrusion push rod 303 on the side of the moving extrusion plate 3, the moving extrusion plate 3 can be driven to fit the stamping workpiece 5, and the stamping workpiece 5 can be fixed again. Finally, the extrusion push rod 303 inside the installation block 301 can be conveniently started, and then the stamping block 302 can be driven to extrude the stamping workpiece 5 to realize side punching operation.

[0027] As Figure 4 , Figure 5 shown in the figure, one end of the bottom plate 1 close to the extrusion column 2 is inclined upward to form a U-shaped. The outer wall of the telescopic push rod 201 is fixed to the top of the bottom plate 1. The top of the extrusion column 2 is fixed to the bottom extended end of the telescopic push rod 201. A groove is provided inside the extrusion column 2, and a rotating ball 203 is arranged at the bottom end of the groove. A compression spring 204 is arranged at the top of the rotating ball 203 close to the inside of the groove. By starting the telescopic push rod 201, the extrusion column 2 can be driven to move downward, so that the extrusion column 2 fits the top of the stamping workpiece 5. The rotating ball 203 is extruded into the groove inside the extrusion column 2, realizing the fit between the extrusion column 2 and the stamping workpiece 5. At the same time, the height of different extrusion columns 2 can be adjusted according to the different heights of the top of the stamping workpiece 5.

[0028] As Figure 2 , Figure 4 shown in the figure, a punching hole corresponding to the stamping block 302 is provided at the inner center of the fixed extrusion plate 401. The cross section of the stamping workpiece 5 is L-shaped. One side of the stamping workpiece 5 is in contact with the fixed extrusion plate 401. One side of the fixed extrusion plate 401 passes through the inside of the fixed block 4 through the connecting bolt 403, and a fixing nut is threadedly connected to the end of the connecting bolt 403 away from the fixed extrusion plate 401. By passing the connecting bolt 403 through the inside of the fixed block 4 and fixing the connecting bolt 403 with a nut, the installation of the fixed extrusion plate 401 can be realized. Then, according to the side inclination angle of the stamping workpiece 5, support plates 402 with different sizes are set. At this time, the stamping workpiece 5 can be conveniently placed on the side of the fixed extrusion plate 401.

[0029] As Figure 5As shown, a chute corresponding to the sliding of the slider 601 is provided inside the connecting plate 202. The top of the slider 601 penetrates through the inside of the chute and is fixedly connected with a fixing bolt 602.

By moving the slider 601, the position of the baffle 6 is adjusted, so that the baffle 6 fits against the side wall of the stamping workpiece 5 with different sizes. Then, the fixing bolt 602 is fixed by the nut, and thus the extrusion fixation of the baffle 6 is achieved.

[0030] When in use, it is possible to conveniently adjust and set different fixed extrusion plates 401 according to the needs of the corresponding stamping workpiece 5. Then, the connecting bolts 403 penetrate through the inside of the fixed block 4, and the connecting bolts 403 are fixedly connected by nuts to achieve the installation of the fixed extrusion plates 401. Different sizes of support plates 402 are set according to the side inclination angle of the stamping workpiece 5. At this time, it is possible to conveniently place the stamping workpiece 5 on the side of the fixed extrusion plate 401. Then, when stamping, the telescopic push rod 201 can be started, which drives the extrusion column 2 to move downward, so that the extrusion column 2 fits against the top of the stamping workpiece 5. The rotating ball 203 is squeezed into the inner groove of the extrusion column 2, realizing the fit between the extrusion column 2 and the stamping workpiece 5.

[0031] At the same time, the height of different extrusion columns 2 can be adjusted according to the different heights of the top of the stamping workpiece 5. And it is possible to conveniently move the position of the baffle 6 through the slider 601, so that the baffle 6 fits against the side walls of the stamping workpieces 5 with different sizes. Then, the fixing bolt 602 is fixed by the nut, and thus the extrusion fixation of the baffle 6 is achieved. At this time, the extrusion push rod 303 on the side of the moving extrusion plate 3 can be started, which drives the moving extrusion plate 3 to fit against the stamping workpiece 5, and the stamping workpiece 5 is fixed again. Finally, the extrusion push rod 303 inside the mounting block 301 can be conveniently started, which drives the stamping block 302 to extrude against the stamping workpiece 5, realizing the side punching operation, and being able to adapt to the fixed processing of stamping workpieces 5 with different sizes.
