[0002] Gas control valves are used to control the flow of gas, and their sealing performance is crucial. Therefore, components that are formed in one piece are usually selected during the production process. Stamping is a common process in the production of valve covers. The coaxiality of the valve cover protrusion and the cover edge is an important measure of the quality of the finished product.

[0003] Chinese utility model patent application number 202221058415.0 discloses a high-precision upper and lower turntable structure for a stamping laser composite machine. By adding an infrared positioning component to the stamping device, automatic centering before stamping can be achieved. However, it is costly and requires maintenance and calibration, making it unsuitable for small-scale production. Utility Model Content

[0023] Please see Figure 1-5 The present invention provides the following technical solution:

[0024] An automatic centering stamping device includes a worktable 1, a hydraulic device 2 mounted above the worktable 1, the output shaft of the hydraulic device 2 pointing vertically downward and connected to a connecting column 3, the lower end of the connecting column 3 being a flange structure, and a pressure head 4 connected to the lower end of the connecting column 3. Different sizes of pressure heads 4 can be selected and replaced according to the requirements of different products. A punch 5 and a placement table 6 are provided inside the worktable 1. The placement table 6 surrounds the outside of the punch 5. A table surface 8 is provided on the worktable 1. Both the placement table 6 and the punch 5 extend upward to the table surface 8. A centering mechanism 7 is provided on the placement table 6. Material 9 can be placed on the placement table 6. The centering mechanism 7 pushes the material 9 to move coaxial with the pressure head 4. When the hydraulic device 2 controls the pressure head 4 to press down, the pressure head 4 and the placement table 6 together clamp the material 9 and drive the material 9 downward. The material 9 covers the punch 5, forming a protrusion, thus completing the stamping process.

[0025] The placement table 6 includes several dampers 61, which are evenly distributed along the outer side of the punch 5. The output shafts of the dampers 61 are connected to a connecting plate 62. Several support columns 64 are placed on the connecting plate 62. Several through holes 81 are evenly opened on the table surface 8 along the circumference of the punch 5. The support columns 64 extend through the corresponding through holes 81 to the top of the table surface 8. A placement plate 63 is placed on the support columns 64. The placement plate 63 is used to place the material 9. When the press head 4 and the placement plate 63 clamp the material 9 and move downward, they need to overcome the resistance of the dampers 61. Space is reserved for the movement of the material 9. At the same time, the stability of the material 9 being clamped between the press head 4 and the placement plate 63 is ensured, thus ensuring product quality.

[0026] Preferably, the distance between the through hole 81 and the axis of the connecting plate 62 can be set to different sizes. When stamping protrusions of different diameters, the required size of the placement plate 63 is different. The support column 64 can be inserted into the through hole 81 at different distances to provide stable support for the placement plate 63.

[0027] The centering mechanism 7 includes several sliders 71. Several grooves 65 are evenly provided on the upper surface of the placement disk 63. The grooves 65 are arranged radially along the placement disk 63. The sliders 71 are slidably connected to the grooves 65. A spring 72 is connected to the side of the slider 71 facing the axis of the placement disk 63. The other end of the spring 72 is fixed on the groove 65. A push rod 712 is connected to the side of the slider 71 away from the spring 72. An adjusting ring 73 is threadedly connected to the outer ring surface of the placement disk 63. Several extrusion grooves 74 are correspondingly provided on the inner ring surface of the adjusting ring 73. The cross-section of the extrusion groove 74 is wedge-shaped. The push rod 712 abuts against the inclined surface of the wedge.

[0028] Under normal conditions, the slider 71 moves towards the edge of the placement plate 63 under the action of the spring 72, ensuring that there is enough space between each slider 71 to facilitate loading and unloading.

[0029] Rotating the adjusting ring 73 causes the wedge-shaped tip of the extrusion groove 74 to move toward the corresponding push rod 712. The inclined surface of the extrusion groove 74 pushes the push rod 712 to move toward the axis of the placement plate 63. All sliders 71 move inward simultaneously to clamp the material 9 together, thereby pushing the material 9 to a position coaxial with the placement plate 63, thus achieving the centering of the material 9.

[0030] A handle 75 is provided on the outer ring surface of the adjusting ring 73. The handle 75 can be located on the side facing the operator to facilitate pushing the adjusting ring 73 to rotate. The upper end face of the slider 71 is connected to the extrusion block 711. The extrusion block 711 extends out of the placement plate 63. The side of the extrusion block 711 facing the axis of the placement plate 63 is set as an arc. The arc structure can increase the contact area with the material 9 and improve the clamping effect. The distance from the highest point of the extrusion block 711 to the plate surface of the placement plate 63 is less than the thickness of the material 9. When the pressure head 4 presses down, it avoids contact with the extrusion block 711 and can stably cover the material 9.

[0031] The punch 5 includes a base 51, a positioning block 52 is provided on the base 51, and the punch body 53 is installed on the base 51 and the positioning block 52. The positioning block 52 ensures that the axis of the punch body 53 is collinear with the axis of the pressure head 4, and the height of the punch body 53 is lower than the height of the plate surface of the placement plate 63.

[0032] Specifically, a centering mechanism 7 is provided on the placement tray 63. The centering mechanism 7 includes several sliders 71. The sliders 71 can slide radially along the placement tray 63. The sliders 71 are connected to the placement tray 63 by springs 72. Under normal conditions, the springs 72 push the sliders 71 towards the edge of the placement tray 63 without affecting the loading and unloading of materials. An adjusting ring 73 is threadedly connected to the outer circumference of the placement tray 63. An extrusion groove 74 is opened on the inner ring surface of the adjusting ring 73. The cross-section of the extrusion groove 74 is wedge-shaped. The outer side of the slider 71 abuts against the wedge-shaped inclined surface of the extrusion groove 74 through the push rod 712. When the adjusting ring 73 is rotated, the extrusion groove 74 pushes the push rod 712 to move through the inclined surface, so that the sliders 71 move radially along the placement tray 63. When all the sliders 71 move inward together, they can clamp the material 9, thereby achieving centering and facilitating the stamping process.
