Description

Technical Field

[0001] This utility model relates to the technical field of cold extrusion equipment, specifically a multifunctional cold extrusion equipment for automotive metal parts. Background Technology

[0002] Cold extrusion is a precision plastic volume forming technology that applies strong pressure and speed to a metal blank in a cold state, forcing it to be extruded from the mold cavity to obtain an extruded part with the required shape, size and mechanical properties. Cold extrusion technology is widely used in the manufacture of automotive metal parts, such as crankshafts, connecting rods and piston pins.

[0003] In the existing technology, in order to reduce the coefficient of friction, reduce wear, and effectively prevent the oxidation reaction of aluminum alloys during the production and processing of automotive metal parts, it is necessary to spray cleaning agent into the mold cavity and the blank in the mold cavity during the feeding process. However, the existing cold extrusion equipment for automotive metal parts does not have the function of automatically spraying cleaning agent during use, which increases the workload of workers. Moreover, the amount of spraying cannot be standardized, which easily leads to incomplete spraying or excessive spraying agent, resulting in waste, which is not conducive to the production and processing of automotive metal parts. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a multifunctional cold extrusion device for automotive metal parts, including a base plate 1, a fixed box 6 fixedly connected to the upper surface of the base plate 1, a fixed seat 7 fixedly connected to the top of the fixed box 6, and a forming cavity 8 opened on the top of the fixed seat 7.

[0019] A receiving box 16 is fixedly connected to the rear side of the base plate 1. A motor 17 is fixedly connected inside the receiving box 16. The output shaft of the motor 17 extends to the outside of the receiving box 16 and is fixedly connected to a rotating rod 18.

[0020] A hollow disk 19 is fixedly connected to the top of the rotating rod 18. A nozzle 20 located above the molding cavity 8 is provided at the other end of the lower surface of the hollow disk 19. A liquid tank mechanism communicating with the interior of the hollow disk 19 is placed on the side wall of the base plate 1.

[0021] After the worker places the blank into the molding cavity 8, the fixed seat 7 can work to drive the motor 17 to drive the rotating rod 18 to rotate, which in turn drives the hollow disk 19 to rotate, so that the nozzle 20 moves to the top of the molding cavity 8.

[0022] After the liquid tank mechanism is working, cleaning agent can be injected into the interior of the hollow disc 19, so that the nozzle 20 sprays the cleaning agent into the interior of the forming cavity 8 and the surface of the blank inside, thereby improving the quality of the finished product after subsequent extrusion molding, reducing the workload of workers, standardizing the spraying metering, and reducing the production cost of automotive parts.

[0023] After the coating is completed, the hollow disc 19 rotates, causing the nozzle 20 to move away from above the forming cavity 8 to avoid affecting the subsequent extrusion work.

[0024] The liquid tank mechanism includes a placement plate 11, a storage tank 12, and a connecting hose 21. The placement plate 11 is fixedly connected to the rear side of the base plate 1. The storage tank 12 is placed on the upper surface of the placement plate 11. A discharge pipe 14 is provided on the top of the storage tank 12. A valve 15 is provided on the discharge pipe 14.

[0026] The inner cavity of the storage tank 12 can store zinc stearate cleaning agent. After the connector 23 is connected to the docking part 22, the valve 15 can be opened and the cleaning agent can be sprayed into the interior of the molding cavity 8 through the intermittent switching of the solenoid valve 24.

[0027] A positioning cylinder 13 adapted to the storage tank 12 is fixedly connected to the upper surface of the placement plate 11. The positioning cylinder 13 facilitates positioning of the storage tank 12 during placement.

[0028] The inner cavity of the fixed box 6 is vertically fixedly connected to a second hydraulic cylinder 9. The top end of the second hydraulic cylinder 9 can be pulled out and extended into the interior of the forming cavity 8, and is fixedly connected to a top plate 10.

[0029] After processing, the second hydraulic cylinder 9 can be extended to drive the top plate 10 to rise inside the forming cavity 8, ejecting the extruded finished product, which facilitates subsequent material handling operations, increases the functionality of the device, and is beneficial for the production of automotive parts.

[0030] Several support rods 2 are vertically fixedly connected to both ends of the upper surface of the base plate 1. The top plate 3 is fixedly connected to the top of the support rods 2. The first hydraulic cylinder 4 is vertically fixedly connected to the upper surface of the top plate 3. The bottom end of the first hydraulic cylinder 4 extends movably to the bottom of the top plate 3 and is fixedly connected to the lifting plate 5. The extrusion die rod 25 is fixedly connected to the lower surface of the lifting plate 5.

[0031] After the first hydraulic cylinder 4 extends, it can drive the lifting plate 5 to descend. The extrusion die 25 is embedded in the molding cavity 8, and the blank can be extruded and molded.

[0032] During operation, after the worker places the blank into the molding cavity 8, the fixed seat 7 works to drive the motor 17 to drive the rotating rod 18 to rotate, which in turn drives the hollow disk 19 to rotate, causing the nozzle 20 to move above the molding cavity 8. After the liquid tank mechanism works, cleaning agent is injected into the hollow disk 19, so that the nozzle 20 sprays the cleaning agent into the inside of the molding cavity 8 and the surface of the blank inside, improving the quality of the finished product after extrusion molding, reducing the workload of the workers, standardizing the spraying metering, reducing the production cost of automotive parts, and after processing, the second hydraulic cylinder 9 can be extended to drive the top plate 10 to rise inside the molding cavity 8 to eject the extruded finished product, which is convenient for subsequent material handling operations.
