The square groove provides precise installation and operating space for the positioning adjustment mechanism 2, and the positioning adjustment mechanism 2 can achieve centered positioning of the material to be stamped through structural adjustment.

[0033] Reference Figures 2-4 The positioning and adjusting mechanism 2 includes a rotating column 201 rotatably connected to the inner wall of the bottom of the square groove. The rotating column 201 is connected to the inner wall of the bottom of the square groove through bearings to ensure smooth rotation and prevent deviation. Fixing components 202 are provided inside the left and right sides of the rotating column 201. The fixing components 202 can fix the rotating column 201 after it is adjusted to a suitable angle to prevent the rotating column 201 from rotating accidentally during the stamping process. Connecting plates 204 are rotatably connected inside the front and rear sides of the rotating column 201. A movable plate 205 is hinged to the side of the connecting plate 204 away from the rotating column 201. The connecting plate 204 can convert the rotational motion of the rotating column 201 into the linear motion of the movable plate 205, realizing the position adjustment of the movable plate 205. A support plate 206 is provided on the upper part of the movable plate 205. The inner wall of the support plate 206 is elastically connected to the mounting roller 209 through an elastic telescopic rod 207. The support plate 206 provides a stable support foundation for the mounting roller 209, ensuring that the mounting roller 209 remains in a stable position during the stamping process. The elastic telescopic rod 207 is formed by two sets of sleeve rods interlocking with each other, which can slide relative to each other to change its overall length. In addition, the elastic telescopic rod 207 has a built-in spring, giving it a certain degree of elasticity. The outer arc surface in the middle of the mounting roller 209 is rotatably connected to a positioning ring 210, which can reduce the friction between the cover plate and the middle of the mounting roller 209. A guide is provided inside the square groove, which can limit the movement direction of the movable plate 205, ensuring that the movable plate 205 moves smoothly along the preset trajectory. The inner wall of the movable plate 205 is provided with a disassembly assembly 3, which can realize the quick disassembly and assembly of the support plate 206 and the movable plate 205, facilitating the maintenance or replacement of components such as the support plate 206 and the mounting roller 209 in the future.

[0034] Reference Figures 2-4The guide component includes a guide rod 203 fixedly connected inside the square groove. The guide rod 203 and the inner wall of the square groove are integrally formed, ensuring a strong connection that is not easily broken. The surface of the guide rod 203 is polished to reduce frictional resistance with the inner wall of the movable plate 205. Two sets of guide rods 203 are provided, with the inner wall of the movable plate 205 slidably connected to the outer arc surface of the guide rod 203. The guide rod 203 passes through the movable plate 205. The fixing component 202 includes a fixing block 2021 fixedly connected inside the front side of the rotating column 201. The fixing block 2021 and the inner side of the rotating column 201 are integrally formed, resulting in high structural strength. It is not easily damaged. The inner wall of the fixing block 2021 is threaded and connected to the screw 2022. The outer wall of the screw 2022 is provided with precise threads, which have a high degree of matching with the threaded hole of the fixing block 2021. Rotating the screw 2022 can realize up and down movement. The bottom of the screw 2022 is fixedly connected to the contact plate 2023. The bottom of the contact plate 2023 is made of rubber material to increase the friction with the bottom of the square groove and improve the fixing effect. The bottom of the contact plate 2023 contacts the bottom of the inner side of the square groove. Through the tight contact between the contact plate 2023 and the bottom of the square groove, the rotating column 201 can be firmly fixed in the current position.

[0035] Furthermore, a circular groove is opened at the center of the rotating column 201, and a horizontal block 208 is fixedly connected to the inner wall of the groove. The inner wall of the groove is smooth and the dimensions are precise, providing a stable installation space for the horizontal block 208. This allows the operator to easily rotate the rotating column 201 by moving the horizontal block 208, improving the ease of operation. The outer wall of the screw 2022 is threaded through and connected to the inner wall of the rotating column 201. A through threaded hole is provided on the rotating column 201 at the position corresponding to the screw 2022. The precision of the threaded hole matches that of the screw 2022, ensuring that the screw 2022 can move stably up and down without shaking when rotating.

[0036] Reference Figures 2-4The disassembly component 3 includes a connecting spring 303, made of high-strength spring steel, which has good elastic recovery ability and can be used repeatedly for a long time. One end of the connecting spring 303 is fixedly connected to the inner wall of the movable plate 205, and the other end is fixedly connected to the limiting post 302. The connection method is welding, which ensures a firm connection. In its natural state, the connecting spring 303 can push the limiting post 302 to maintain its initial position, providing a stable insertion force for the limiting post 302. The bottom of the support plate 206 is fixedly connected to an insert block 304. The insert block 304 and the support plate 206 are integrally formed, making the structure stable. The upper part of the movable plate 205 has a support groove. The outer wall of the insert block 304 is inserted into the inner wall of the support groove. The shape of the support groove is adapted to the insert block 304, ensuring that the insert block 304 can be accurately inserted, achieving the initial positioning of the support plate 206 and the movable plate 205. The center of the insert block 304 is... A positioning hole is provided, the inner diameter of which matches the outer arc surface of the limiting post 302. The inner wall of the positioning hole is smooth to ensure that the limiting post 302 can be smoothly inserted into the positioning hole, thereby fixing the support plate 206 and the movable plate 205. The outer wall of the limiting post 302 is slidably connected to the inner wall of the movable plate 205. A through sliding hole is provided on the movable plate 205 corresponding to the position of the limiting post 302. The inner wall of the sliding hole is smoothed to reduce the frictional resistance when the limiting post 302 slides. A gripping plate 301 is fixedly connected to the side of the limiting post 302 away from the connecting spring 303. The gripping plate 301 can drive the two sets of limiting posts 302 to move synchronously. An inclined surface is provided on the side of the limiting post 302 away from the gripping plate 301, with the inclined surface facing upward. When the insert block 304 is inserted into the support groove, the inclined surface can contact and receive force with the bottom of the insert block 304, causing the limiting post 302 to retract automatically without the need to manually pull the gripping plate 301, thus improving the ease of installation.

[0037] Working principle: When using this continuous stamping die for the cover plate, first install the support plate 206, then directly insert the bottom insert 304 into the support groove on the upper part of the movable plate 205. The bottom of the insert 304 contacts the upward inclined surface of the limiting post 302 and applies force, pushing the limiting post 302 along the through-hole of the movable plate 205 to compress the connecting spring 303. When the insert 304 is fully inserted into the support groove, its central positioning hole aligns with the limiting post 302, the connecting spring 303 returns to its natural state and pushes the limiting post 302 into the positioning hole, completing the fixation of the support plate 206 and the movable plate 205.

[0038] After installation, the cover plate width positioning is prepared by the positioning adjustment mechanism 2: The operator moves the horizontal block 208 in the central groove of the rotating column 201, causing the rotating column 201 to rotate on the inner wall of the bottom of the square groove; the rotating column 201 simultaneously drives the connecting plates 204 hinged on the front and rear sides to move. The connecting plates 204 convert the rotational motion of the rotating column 201 into the linear motion of the movable plate 205, so that the two sets of movable plates 205 slide smoothly along the two sets of integrally formed guide rods 203 in the square groove, thereby adjusting the position of the upper support plate 206 and the mounting roller 209 of the movable plate 205 until the positioning ring 210 matches the width of the cover plate to be stamped. After the position adjustment is completed, the screws 2022 of the fixing components 202 on the left and right sides of the rotating column 201 are rotated. The screws 2022 move downward along the threaded holes of the fixing block 2021, causing the bottom rubber contact plate 2023 to make close contact with the bottom of the square groove. Through friction, the rotating column 201 Securely fasten to prevent the rotating column 201 from rotating accidentally during the stamping process.

[0039] During the stamping operation, the material to be stamped is conveyed into the mold. The positioning ring 210 in the middle of the mounting roller 209 guides and positions the material. At the same time, the elastic telescopic rod 207 on the inner wall of the support plate 206 can automatically extend and retract according to the thickness of the cover plate to adjust the height of the mounting roller 209, ensuring that the positioning ring 210 is always in contact with the cover plate, thus achieving centered positioning of the material.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
