Description

Technical Field

[0001] The utility model belongs to the technical field of stamping dies, and in particular relates to a novel stamping forming die. Background Art

[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. It is called a cold stamping die, commonly known as a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the desired parts.

[0003] According to the patent with announcement number CN218015214U, a new stamping die for a motor is disclosed. The new stamping die for a motor comprises a die bottom plate body, the upper end of the die bottom plate body is attached to a bottom die body and is slidably connected to a slide groove opened at the upper end of the die bottom plate body, a support base is fixed to the bottom wall of the die bottom plate body, and a rectangularly distributed connecting column body is fixed to the side wall of the bottom die body, a top seat body parallel to the bottom die body is fixed to the top of the connecting column body, a driving pump body is fixed to the center of the top seat body, the output end of the driving pump body passes through the interior of the top seat body and extends to the bottom of the top seat body, and a limiting mechanism is arranged on both sides of the functional top bin.

The stamping mechanism 2 specifically includes a support rod 202, and the bottom surface of the support rod 202 is fixedly connected with two symmetrical top plates 201, and the bottom surfaces of the two top plates 201 are fixedly connected to the upper surface of the workbench 1. The bottom surface of the support rod 202 is fixedly connected with a cylinder 203, and the telescopic end of the cylinder 203 is fixedly connected with a connecting plate 204, and the bottom surface of the connecting plate 204 is fixedly connected with an upper mold 205. The outer surface of the connecting plate 204 is fixedly connected with two symmetrical sliders 207, and the side surfaces of the two top plates 201 close to each other are both provided with a slide groove 206, and the outer surfaces of the two sliders 207 are both slidably connected with the inside of the slide groove 206. Through the cooperation of the slide groove 206 and the slider 207, the guiding of the connecting plate 204 can be realized, the deviation of the stamping position can be avoided, and the accuracy of the stamping can be improved. When in use, the cylinder 203 is turned on to drive the connecting plate 204 to move downward, drive the slider 207 to move inside the slide groove 206, and drive the upper mold 205 to move downward, so as to punch the workpiece 4 in the lower mold 3.

[0028] See also Figure 1 and Figure 2 As shown, a lower mold 3 is provided inside the workbench 1, a workpiece 4 is provided inside the lower mold 3, a sealed door 5 is provided on the front of the workbench 1, the sealed door 5 and the workbench 1 are rotatably connected by hinges, and a groove handle is provided on the surface of the sealed door 5. A dustproof net 6 is provided inside the sealed door 5, and a storage drawer 7 is provided inside the workbench 1. A layer of hard rubber material that is non-slip and non-irritating is provided on the handle on the surface of the storage drawer 7, and its internal space can be used to store some tools. A heat dissipation fan 8 is fixedly connected to the inner wall of the workbench 1, and the heat dissipation of the lower mold 3 can be dissipated by the heat dissipation fan 8, and the blown heat will be discharged through the exhaust port on the surface of the sealed door 5, and the dustproof net 6 is provided inside the exhaust port to prevent external dust and impurities from entering the workbench 1 through the exhaust port.

[0029] See also Figure 4 and Figure 5 As shown, the workbench 1 is provided with an ejection mechanism 9 inside, and the ejection mechanism 9 specifically includes a mounting plate 901 and a movable plate 903. The outer surface of the mounting plate 901 is fixedly connected to the inside of the workbench 1, and the upper surface of the mounting plate 901 is fixedly connected to two symmetrical limiting rods 902. The outer surfaces of the two limiting rods 902 are both slidably connected to the inside of the movable plate 903, and the upper surfaces of the two limiting rods 902 are both fixedly connected to the inner top wall of the workbench 1. The limiting rods 902 can limit the movable plate 903 to prevent the movable plate 903 from deviating from its motion trajectory. The movable plate 903 is fixedly connected to two symmetrical first fixed plates 905 inside, and the upper surfaces of the two first fixed plates 905 are fixedly connected to elastic members 904 (in this embodiment, the elastic members 904 are springs). The lower mold 3 is fixedly connected to two symmetrical second fixed plates 906 inside, and the top ends of the two elastic members 904 are fixedly connected to the bottom surface of the second fixed plate 906. Under the action of its elastic force, the ejection plate 908 can be quickly reset. The first fixed plate 905 and the movable plate 903, the second fixed plate 906 and the lower mold 3 are fixed by screws. When the elastic member 904 is damaged, the damaged elastic member 904 can be replaced by removing the screws.

[0030] See also Figure 4 and Figure 5As shown, the upper surface of the movable plate 903 is fixedly connected to a movable rod 907, the outer surface of the movable rod 907 is slidably connected to the interior of the lower mold 3, and the upper surface of the movable rod 907 is fixedly connected to an ejection plate 908, the outer surface of the ejection plate 908 is slidably connected to the interior of the lower mold 3. As the upper mold 205 stamps the workpiece 4, the ejector plate 908 will be driven to move downward, the movable rod 907 will be driven to move downward, and the movable plate 903 will be driven to move on the surface of the limit rod 902. As the movable plate 903 moves, the elastic member 904 will be stretched, so that the elastic member 904 generates elastic force. When the stamping is completed, the force acting on the ejector plate 908 is withdrawn. Under the elastic force of the elastic member 904, the ejector plate 908 can be quickly reset and the formed workpiece 4 can be ejected from the inside of the lower mold 3. The first fixed plate 905 and the movable plate 903, the second fixed plate 906 and the lower mold 3 are all fixed by screws. When the elastic member 904 is damaged, the damaged elastic member 904 can be replaced by removing the screws. This solves the problem that when the existing device is stuck, a tool is needed to remove the workpiece 4 from the lower mold 3, thereby achieving the purpose of rapid demoulding and effectively improving production efficiency.

[0031] The specific working principle of the utility model is as follows: when in use, the cylinder 203 is turned on, the connecting plate 204 is driven to move downward, the slider 207 is driven to move inside the slide groove 206, and the upper mold 205 is driven to move downward, so that the workpiece 4 in the lower mold 3 can be punched. As the upper mold 205 punches the workpiece 4, the ejector plate 908 is driven to move downward, the movable rod 907 is driven to move downward, and the movable plate 903 is driven to move on the surface of the limit rod 902. As the movable plate 903 moves, the elastic member 904 is stretched, so that the elastic member 904 generates elastic force. When the punching is completed, The force acting on the ejector plate 908 is withdrawn, and under the elastic force of the elastic member 904, the ejector plate 908 can be quickly reset and the formed workpiece 4 can be ejected from the inside of the lower mold 3. The first fixed plate 905 and the movable plate 903, the second fixed plate 906 and the lower mold 3 are all fixed by screws. When the elastic member 904 is damaged, the damaged elastic member 904 can be replaced by removing the screws, which solves the problem that in the existing device, when the mold is stuck, tools are needed to remove the workpiece 4 from the lower mold 3, thereby achieving the purpose of rapid demoulding and effectively improving production efficiency.
