[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4 This utility model provides a thermocouple aluminum cap stamping forming device, including a frame 1. A hydraulic cylinder 4 is fixed to the top of the frame 1 by bolts. The movable end of the hydraulic cylinder 4 passes through the frame 1 and is fixed to a stamping head 5 by bolts. A lower mold 2 is fixed to the bottom inner wall of the frame 1 by bolts. A PE film 3 is provided on the bottom inner wall of the frame 1, and the unfolded PE film 3 covers the mold cavity of the lower mold 2. A positioning groove 13 and a limiting groove 14 are provided on the top of the lower mold 2, and the limiting groove 14 is located below the positioning groove 13. A limiting component for auxiliary fixing of the PE film 3 is provided on the top of the lower mold 2. An installation component for auxiliary limiting of the winding roller of the PE film 3 is provided on the bottom inner wall of the frame 1.

[0024] In use, first, the PE film 3 is laid on top of the lower mold 2, and part of the PE film 3 is located in the limiting groove 14. Then, the aluminum material is placed in the positioning groove 13. At this time, the aluminum material will press on the PE film 3. Start the hydraulic cylinder 4. The extension of the hydraulic cylinder 4 will drive the stamping head 5 to move downward, thereby stamping the aluminum material and stamping it into an aluminum cap. Since there is a PE film 3 between the aluminum material and the forming cavity, the aluminum material will not directly contact the forming cavity, thereby avoiding scratches on the aluminum material during stamping and improving the stamping quality of the aluminum material.

[0025] In this utility model, the limiting component includes a fixed frame 11 fixed to the bottom of the lower mold 2 and a rotating frame 15 rotating on the top of the lower mold 2. The inner top walls of the fixed frame 11 and the rotating frame 15 are both fixed with arc-shaped elastic plates 12 by bolts. Both arc-shaped elastic plates 12 are made of elastic material, preferably elastic steel. The two arc-shaped elastic plates 12 are axially symmetrically distributed, and the arc-shaped elastic plates 12 and the lower mold 2 together clamp the unfolded PE film 3. A clearance groove 16 is provided on one side of the lower mold 2, and the clearance groove 16 is connected to the limiting groove 14. The top of the lower mold 2 is provided with a locking mechanism to fix the position of the rotating frame 15.

[0026] During the PE film 3 laying process, the PE film 3 is first passed under the arc-shaped elastic plate 12 below the fixed frame 11. At this time, the arc-shaped elastic plate 12 will limit the PE film 3, making it difficult for it to move backward. Then, the PE film 3 is passed under the arc-shaped elastic plate 12 below the rotating frame 15. At this time, the arc-shaped elastic plate 12 on the rotating frame 15 is located in the clearance groove 16, so that the PE film 3 cannot be fixed. After the PE film 3 is laid, the rotating frame 15 is rotated so that the arc-shaped elastic plate 12 on the rotating frame 15 and the lower mold 2 clamp the PE film 3 together, so that the PE film 3 can only move in the middle direction and is difficult to move to the sides, thereby limiting the PE film 3 and preventing the PE film 3 from easily shifting during the stamping process, thus improving the protective effect of the device.

[0027] The locking mechanism includes a limiting block 17 fixed to the top of the lower mold 2. A mounting groove 18 is provided on one side of the limiting block 17, and an elastic ball 19 is bonded in the mounting groove 18. The elastic ball 19 is made of elastic rubber. Arc-shaped grooves 20 are provided on both sides of the inner wall of the rotating frame 15. During the rotation of the rotating frame 15, the rotating frame 15 will squeeze the elastic ball 19 to deform, thereby enabling the rotating frame 15 to rotate. When the elastic ball 19 is located at the arc-shaped groove 20, the squeezed and deformed elastic ball 19 returns to its original position and is locked into the arc-shaped groove 20, fixing the rotating frame 15 so that it will not rotate easily and improving the stability of the rotating frame 15.

[0028] The installation component includes a fixing block 6 fixed to the inner wall of the bottom of the frame 1. A pressure cover 9 is rotatably connected to the top of the fixing block 6, and a winding roller is located between the fixing block 6 and the pressure cover 9. An adsorption component is provided on the top of the fixing block 6 to press down the pressure cover 9. The winding roller is placed between the fixing block 6 and the pressure cover 9, and the adsorption component is used to fix the pressure cover 9 and the fixing block 6. Thus, the PE film 3 can be laid by simply pulling one end of the PE film 3, which improves the convenience of laying the PE film 3.

[0029] The adsorption assembly includes a first magnetic block 7 fixed on the top of the fixing block 6, and a second magnetic block 8 bonded to one end of the pressure cover 9. The first magnetic block 7 and the second magnetic block 8 are attracted to each other, which fixes the fixing block 6 and the pressure cover 9, thereby facilitating the rotation of the winding roller.

[0030] The top of the frame 1 is fixed with at least one placement frame 10 by bolts, and the take-up roller can be fitted onto the placement frame 10 for placing excess take-up rollers.

[0031] It should be noted that the lower mold 2, PE film 3, hydraulic cylinder 4, stamping head 5, first magnetic block 7, second magnetic block 8, arc-shaped elastic plate 12, and elastic ball 19 in this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods, and will not be elaborated on here.

[0032] The working principle of this utility model is as follows: In use, the take-up roller is placed between the fixing block 6 and the pressure cover 9. The first magnetic block 7 and the second magnetic block 8 attract each other, fixing the fixing block 6 and the pressure cover 9. Pulling one end of the PE film 3 allows it to pass under the arc-shaped elastic plate 12 on the fixing frame 11. At this time, the arc-shaped elastic plate 12 limits the PE film 3, making it difficult for it to move backward. Then, the PE film 3 passes under the arc-shaped elastic plate 12 below the rotating frame 15. At this time, the arc-shaped elastic plate 12 on the rotating frame 15 is located in the clearance groove 16, thus preventing the PE film 3 from being fixed. When the PE film 3... After the PE film is laid, the rotating frame 15 is rotated so that the arc-shaped elastic plate 12 on the rotating frame 15 and the lower mold 2 clamp the PE film 3 together. This makes it possible for the PE film 3 to move only in the middle direction and difficult to move to the sides, thus limiting the PE film 3 and preventing it from easily shifting during the stamping process. The hydraulic cylinder 4 is then activated, and the extension of the hydraulic cylinder 4 will drive the stamping head 5 to move downward, thereby stamping the aluminum material into an aluminum cap. Because there is a PE film 3 between the aluminum material and the forming cavity, the aluminum material will not directly contact the forming cavity, thus avoiding scratches on the aluminum material during stamping and improving the stamping quality of the aluminum material.

[0033] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
