The cold extrusion punch is connected to the pressure device, and the pressure device is connected to the cold extrusion drive device. A positioning rod is provided on one side of the cold extrusion die, and the positioning rod cooperates with a positioning sleeve on one side of the cold extrusion punch.

[0004] However, the inventor of the above device believes that there are certain defects. The above device lacks a demolding mechanism. The aluminum shell is formed by pressure extrusion and is in close contact with the punch and die. There is friction between the aluminum shell and the punch and die, which can easily cause demolding difficulties. Therefore, this utility model provides a cold extrusion sidewall explosion-proof aluminum shell stamping mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a cold-extruded sidewall explosion-proof aluminum shell stamping mechanism to solve the above-mentioned problems, so as to solve the problem that the existing technology lacks a demolding mechanism and that there is friction between the aluminum shell and the punch and die, which easily causes demolding difficulties.

[0006] This utility model is achieved through the following technical solution: a cold-extruded sidewall explosion-proof aluminum shell stamping mechanism, including a processing table, a die and a fixed slide rod fixedly connected to the top of the processing table, a mold cavity opened at the top of the die, a movable plate slidably connected to the fixed slide rod, a punch corresponding to the mold cavity fixedly connected to the bottom of the movable plate, a lifting mechanism for driving the movable plate to rise and fall at the top of the fixed slide rod, an inner cavity opened inside the die, an impact slide rod slidably connected inside the inner cavity, one end of the impact slide rod extending to the inner bottom wall of the mold cavity, a baffle fixedly connected to the impact slide rod, a spring provided at the bottom of the baffle, an extrusion mechanism for extruding the impact slide rod to descend at the bottom of the processing table, the extrusion mechanism including a side rod fixed to one end of the impact slide rod, a base box fixedly connected to the bottom of the processing table, a connecting rotating rod rotatably connected to one end of the base box, and a rotating frame fixedly connected to one end of the connecting rotating rod.

[0007] Preferably, the lifting mechanism includes a top plate fixed to the top of the fixed slide rod, and a hydraulic cylinder is fixedly connected to the bottom of the top plate. The telescopic end of the hydraulic cylinder is fixedly connected to the movable plate, and the movable plate is controlled to lift and slide on the fixed slide rod by activating the hydraulic cylinder.

[0008] Preferably, the rotating frame includes two fixed plates and two pressing rods. The two pressing rods are fixed between the two fixed plates. By driving the rotating frame to rotate, the pressing rods strike the side rods and pull the impact slide rods downward.

[0009] Preferably, a winding drum is fixedly connected to the outer surface of the connecting rod inside the base box. A pull rope is wound on the winding drum, and one end of the pull rope extends to the top of the processing table. By pulling the pull rope upward, the connecting rod is driven to rotate.

[0010] Preferably, a magnet is fixedly connected to one end of the pull rope, and a connecting rod corresponding to the magnet is fixedly connected to the bottom of the movable plate. An iron block is embedded in one end of the connecting rod, and when the movable plate descends, it is attracted to the magnet through the iron plate at one end of the connecting rod.

[0011] Preferably, a spring is fixedly connected to the inner side wall of the base box, and one end of the spring is fixedly connected to the connecting rod. The spring allows the connecting rod to rotate rapidly in the opposite direction when no force is applied.

[0012] Preferably, the connecting rod is a telescopic rod, and the iron block is embedded in the telescopic end of the connecting rod.

[0013] This utility model provides a cold-extruded sidewall explosion-proof aluminum shell stamping mechanism, which has the following beneficial effects:

[0014] The device drives the connecting rod to rotate, and the rotating frame at one end of the connecting rod squeezes the side rod to push the impact slide rod downward. When the rotating frame rotates away from the side rod, the spring rebound quickly pushes the impact slide rod upward and slides. The top of the impact slide rod strikes the aluminum shell upward, causing the aluminum shell to quickly detach from the mold cavity, thus improving the demolding efficiency of the aluminum shell.

[0015] This device uses a magnet and a connecting rod to lower the movable plate, causing the magnet to adhere to the bottom of the connecting rod. When the movable plate rises, it pulls the rope at one end of the magnet upwards. Under the action of the winding drum, the connecting rod is automatically pulled to rotate. After the magnet rises a certain distance, it separates from the bottom of the connecting rod. Under the rebound action of the spring, the rope is quickly wound in the opposite direction to facilitate the next rotation of the rotating frame. Moreover, this mechanism does not require the installation of other drive equipment, reducing the cost of use. Attached Figure Description

Detailed Implementation

[0023] This utility model embodiment provides a cold-extruded sidewall explosion-proof aluminum shell stamping mechanism.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A cold-extruded explosion-proof aluminum shell stamping mechanism includes a processing table 1. A die 2 and a fixed slide rod 11 are fixedly connected to the top of the processing table 1. A mold cavity 21 is opened on the top of the die 2. A movable plate 3 is slidably connected to the fixed slide rod 11. A punch 4 corresponding to the mold cavity 21 is fixedly connected to the bottom of the movable plate 3. An aluminum billet is placed inside the mold cavity 21. By driving the movable plate 3 to descend, the punch 4 extrudes and forms the aluminum billet inside the mold cavity 21.

[0025] Please refer to it again. Figure 1 The top of the fixed slide bar 11 is provided with a lifting mechanism for driving the movable plate 3 to rise and fall. The lifting mechanism includes a top plate 12 fixed to the top of the fixed slide bar 11, and a hydraulic cylinder 13 fixedly connected to the bottom of the top plate 12. The telescopic end of the hydraulic cylinder 13 is fixedly connected to the movable plate 3. By activating the hydraulic cylinder 13, the movable plate 3 is pushed to rise and slide on the fixed slide bar 11. Under the action of the fixed slide bar 11, the stability of the movable plate 3 during the rising and falling process is improved.

[0026] Please refer to it again. Figure 1 , Figure 2 and Figure 4 The cavity 2 has an inner cavity 22, and an impact slide rod 5 is slidably connected inside the cavity 22. One end of the impact slide rod 5 extends to the inner bottom wall of the cavity 21. A baffle 52 is fixedly connected to the impact slide rod 5. A spring 51 is provided at the bottom of the baffle 52. The spring 51 is sleeved on the outer surface of the impact slide rod 5. The bottom of the processing table 1 is provided with a pressing mechanism to press the impact slide rod 5 down. The pressing mechanism pushes the impact slide rod 5 down. When the pressing mechanism moves away from the impact slide rod 5, the spring 51 rebounds and quickly drives the impact slide rod 5 up and slides to strike the aluminum shell.

[0027] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 5 The extrusion mechanism includes a side rod 6 fixed to one end of the impact slide bar 5. A base box 9 is fixedly connected to the bottom of the processing table 1. A connecting rod 8 is rotatably connected to one end of the base box 9. A rotating frame 7 is fixedly connected to one end of the connecting rod 8. The rotating frame 7 is rectangular and includes two fixed plates and two extrusion rods. The two extrusion rods are fixed between the two fixed plates. When the rotating frame 7 rotates around the connecting rod 8, the side rod 6 is extruded by the extrusion rods on the rotating frame 7 to push the impact slide bar 5 downward. When the extrusion rods rotate away from the side rod 6, the impact slide bar 5 quickly slides back to its original position by the spring 51.

[0028] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 5A winding drum 81 is fixedly connected to the outer surface of the connecting rod 8 inside the base box 9. A pull rope 82 is wound on the winding drum 81. One end of the pull rope 82 extends to the top of the processing table 1. By pulling the pull rope 82, the connecting rod 8 is driven to rotate under the action of the winding drum 81, thereby driving the rotating frame 7 at one end of the connecting rod 8 to rotate. A spring 91 is fixedly connected to the inner wall of the base box 9. One end of the spring 91 is fixedly connected to the connecting rod 8. When the connecting rod 8 rotates, the spring 91 is compressed. When the tension on the pull rope 82 is removed, the spring 91 rebounds and drives the winding drum 81 to rotate in the opposite direction to automatically wind up the pull rope 82.

[0029] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 5 A magnet 10 is fixedly connected to one end of the pull rope 82. A connecting rod 31 corresponding to the magnet 10 is fixedly connected to the bottom of the movable plate 3. An iron block is embedded in one end of the connecting rod 31. The connecting rod 31 is a telescopic rod. The iron block is embedded in the telescopic end of the connecting rod 31. When the movable plate 3 descends, the end of the connecting rod 31 with the iron block attracts the magnet 10. When the movable plate 3 rises, the connecting rod 31 is telescopic, causing the movable plate 3 to rise a certain distance and pull the magnet 10 to rise, thereby pulling the pull rope 82 to rise. After the pull rope 82 is taut, the movable plate 3 continues to rise, causing the magnet 10 to disconnect from one end of the connecting rod 31.

[0030] Working principle: The device is installed in a suitable location and connected to a municipal power supply. An aluminum billet is placed inside the mold cavity 21. The hydraulic cylinder 13 is activated to drive the movable plate 3 downwards, causing the punch 4 to extrude the aluminum billet inside the mold cavity 21. When the movable plate 3 descends, one end of the connecting rod 31 is attracted to the magnet 10. When the movable plate 3 rises, the connecting rod 31 extends and retracts, causing the movable plate 3 to rise a certain distance before pulling the magnet 10 upwards, thereby pulling the pull rope 82 upwards. The device then reaches the winding drum 8. Under the action of 1, the connecting rod 8 is driven to rotate. The rotating frame 7 at one end of the connecting rod 8 presses the side rod 6 on the impact slide 5 to push the impact slide 5 down. When the pressing rod of the rotating frame 7 moves away from the side rod 6, the spring 51 rebounds and quickly drives one end of the impact slide 5 to hit the aluminum shell, making it easy to remove the aluminum shell from the inside of the mold cavity 21. After the movable plate 3 rises a certain distance, the magnet block 10 is disconnected from the pull rope 82. Then, the spring 91 rebounds and drives the winding drum 81 to rotate in the opposite direction to automatically wind up the pull rope 82.
