Description

Technical Field

[0001] This utility model belongs to the field of aluminum plate processing technology, and specifically relates to a cold extrusion device for aluminum plate production. Background Technology

[0002] Cold extrusion technology for aluminum sheets is a metal plastic processing method. The process involves applying high pressure to aluminum material through a mold at room temperature, causing it to undergo plastic deformation to obtain the desired shape and size. This enables the production of aluminum products with high precision and complex shapes, while improving the mechanical properties of the material, such as strength and hardness.

[0003] In the current processing, workers usually manually load and unload materials. On the one hand, during the cold extrusion process, the metal undergoes plastic deformation, and the deformation work is converted into heat energy, which raises the temperature of the aluminum plate. If the material accidentally touches the worker's skin, it will cause burns. On the other hand, workers need to put their arms between the molds. If the machine is started by mistake, it will cause serious crushing injuries to the worker's arms. Utility Model Content

[0018] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-4 The cold extrusion apparatus for aluminum plate production shown includes a base plate 1, a support plate 2 fixedly connected to one side of the top of the base plate 1, a mold base 4 fixedly mounted on the top of the base plate 1, a rotating ring 5 inserted and rotatably connected inside the mold base 4, a plurality of lower molds 8 fixedly connected to the top of the rotating ring 5, a slide rail 19 fixedly connected to one side edge of the bottom of the rotating ring 5, and the slide rail 19 slidably connected to the inner wall of the mold base 4, and evenly distributed teeth 20 fixedly connected to the other side edge of the rotating ring 5. A first mold 8 is fixedly mounted on the top of the base plate 1 via a fixing plate. The first drive mechanism 6 and the second drive mechanism 7 both include a motor 9 fixedly connected to the fixed plate and a gear 10 fixedly connected to the output end of the motor 9. The gear 10 and the teeth 20 are matched. After extrusion, the first drive mechanism 6 and the second drive mechanism 7 are powered on and drive the lower mold 8 to rotate through the teeth 20, thereby rotating the lower mold 8 out between the extrusion equipment 3 and the mold base 4, and simultaneously rotating the other lower mold 8 into the extrusion equipment 3 and the mold base 4, making it safer and more convenient for workers to load and unload materials.

[0020] The mold base 4 has a sliding groove inside. The rotating ring 5 includes several connecting arms and several connecting rings 13. The mold base 4 includes a mold cylinder 12 that is slidably connected inside the connecting rings 13. With this design, the mold cylinder 12 slides into the sliding groove under the extrusion of the extrusion equipment 3, thereby avoiding the pressure on the lower mold 8, so that the lower mold 8 does not act as a load-bearing structure and extends its service life.

[0021] Both sides of the outer wall of the mold cylinder 12 are fixedly connected with protruding ears 14. The bottom of the protruding ears 14 is fixedly connected with a plug rod 15. The plug rod 15 is inserted and slidably connected to the bottom of the rotating ring 5. A spring 16 is sleeved on the outside of the plug rod 15. Through this design, the rebound of the spring 16 can make the mold cylinder 12 automatically pop out and slide into the inside of the groove, thereby avoiding interference between the rotation trajectory of the lower mold 8 and the mold seat 4.

[0022] An electric push rod 18 is fixedly installed inside the sliding groove. A top column 11 is inserted into and slidably connected to the bottom of the mold cylinder 12. A magnetic mating ring 22 is fixedly connected to the top of the top column 11. An electromagnet 21 is fixedly installed at the bottom of the mold cylinder 12. The drive rod of the electric push rod 18 pushes out the top column 11, thereby simultaneously pushing out the aluminum plate inside the mold cylinder 12, which facilitates the loading and unloading of materials by workers. At the same time, the electromagnet 21 is energized to attract the magnetic mating ring 22. Even after being unscrewed, the top column 11 can still provide support for the aluminum plate without the need for workers to manually pull the aluminum plate.

[0023] The bottom of the mold cylinder 12 is fixedly connected to a second contact plate 23, and the inside of the sliding groove is fixedly connected to a first contact plate 17. The drive rod of the electric push rod 18 is inserted and slidably connected to the top of the first contact plate 17. Through this design, the first contact plate 17 and the second contact plate 23 are in contact, avoiding the electromagnet 21 from appearing as a contact structure.

[0024] The top of the top post 11 is a cone-shaped structure, which prevents the top post 11 from sliding completely out of the mold cylinder 12.

[0025] Working principle:

[0026] After extrusion, the first drive mechanism 6 and the second drive mechanism 7 are powered on and drive the lower die 8 to rotate through the teeth 20, thereby rotating the lower die 8 out between the extrusion equipment 3 and the die seat 4, while simultaneously rotating the other lower die 8 into the extrusion equipment 3 and the die seat 4, making it safer and more convenient for workers to load and unload materials.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
