Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, specifically an aluminum profile continuous extrusion press. Background Technology

[0002] Industrial aluminum profiles are alloy materials with aluminum as the main component. Different cross-sectional shapes of aluminum materials are obtained by hot melting and extruding aluminum rods. However, the mechanical properties and application fields of the produced industrial aluminum profiles vary depending on the proportion of alloy added. After surface oxidation, industrial aluminum profiles have a very attractive appearance. When assembled into products, specialized aluminum profile accessories are used, eliminating the need for welding. They are widely used in automated machinery, enclosure frames, conveyor belts on assembly lines, and more.

[0003] In existing aluminum profile extrusion equipment, the slow stroke of the high-power hydraulic press during the feeding of aluminum billets into the extrusion unit results in a long hydraulic press reset process, which affects the equipment's processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a continuous extrusion press for aluminum profiles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[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] See Figures 1-3 In this embodiment of the utility model, an aluminum profile continuous extrusion press includes a base 1, a first mounting frame 2 fixedly connected to one side of the base 1, a second mounting frame 3 fixedly connected to the other side of the base 1, a servo motor 18 fixedly connected to the first mounting frame 2, a rotating frame 19 fixedly connected to the output shaft of the servo motor 18, an oil pump 20 fixedly connected to the rotating frame 19, and two sets of hydraulic telescopic machines 21 connected to the oil pump 20. The oil pump 20 is equipped with two sets of oil outlets and oil inlets, and each of the two sets of hydraulic telescopic machines 21 is connected to a set of oil outlets and oil inlets.

[0019] The second mounting frame 3 is provided with a mounting groove 4, and an extrusion mold 5 is provided in the mounting groove 4. One end of a plurality of fixed rods 6 is fixedly connected to the side of the second mounting frame 3 near the first mounting frame 2. A stop block 8 is fixedly connected to the other end of the fixed rods 6. A sliding tube 7 is slidably connected to the fixed rods 6. A telescopic frame 10 is fixedly connected between the plurality of sliding tubes 7. A first spring 9 is provided on the side of the sliding tube 7 away from the second mounting frame 3 and sleeved on the fixed rod 6. A mounting slot 22 is provided on the side of the telescopic frame 10 near the first mounting frame 2. The mounting slot 22 cooperates with the output shaft of a set of hydraulic telescopic machines 21. A mounting seat 12 is fastened to the side of the telescopic frame 10 near the second mounting frame 3 by mounting bolts 11. An extrusion rod 13 is fixedly connected to the mounting seat 12 and cooperates with the extrusion mold 5. A sleeve 23 is slidably connected to the outside of the extrusion rod 13. A second spring 24 is provided between the sleeve 23 and the mounting seat 12 and sleeved on the extrusion rod 13.

[0020] A support assembly mounted on the base 1 is provided between the extrusion rod 13 and the extrusion die 5;

[0021] This invention first places the bar stock on the lifting assembly, which then lifts the bar stock between the extrusion rod 13 and the extrusion die 5. Next, the oil pump 20 drives a set of hydraulic telescopic mechanisms 21 connected to the mounting slot 22 to extend. Simultaneously, another set of hydraulic telescopic mechanisms 21 is drawn in by the oil pump 20, causing it to retract. The hydraulic telescopic mechanisms 21 then move the telescopic frame 10 closer to the second mounting frame 3 via the mounting slot 22. The second mounting frame 3 moves the extrusion rod 13 and the sleeve 23 towards the second mounting frame 3, compressing the first spring 9. The bar stock is then inserted into the sleeve 23, completing the loading process. Afterward, the lifting assembly retracts and resets, allowing the next set of bar stock to be placed on the lifting assembly, thus performing pre-loading.

[0022] Then the telescopic frame 10 continues to move. When the sleeve 23 contacts the extrusion die, the sleeve 23 stops moving. At this time, the extrusion rod 13 is inserted into the sleeve 23, thereby squeezing the bar material in the sleeve 23 into the extrusion die 5 and compressing the second spring 24. During this process, the sleeve 23 protects the bar material, thereby avoiding extrusion failure caused by the bar material being squeezed and deformed.

[0023] After a set of bar stock is extruded, the servo motor 18 drives the rotating frame 19 to rotate 180°, thereby rotating the extended hydraulic telescopic machine 21 out of the mounting slot 22 and rotating the output shaft of the retracted hydraulic telescopic machine 21 to the mounting slot 22. During this process, the telescopic frame 10 loses its driving force, the first spring 9 pushes the telescopic frame 10 to reset, and the second spring 24 pushes the sleeve to reset. At this time, the next set of bar stock can be continuously extruded.

[0024] In one instance of this embodiment, please refer to Figures 1-3 The fixed rod 6 is an electromagnet, and the sliding tube 7 is a copper tube. According to Lenz's law, eddy currents are generated when the copper tube slides between the electromagnet and the electromagnet. The magnetic field of the eddy currents hinders the relative sliding between the copper tube and the electromagnet, thereby applying a damping force between the copper tube and the electromagnet, thus preventing mechanical damage caused by the rapid sliding of the copper tube.

[0025] In one instance of this embodiment, please refer to Figures 1-3 The extrusion rod 13 is provided with a clamping top groove 14 at one end near the second mounting frame 3, and the extrusion die 5 is provided with a clamping slot 15 on one side near the extrusion rod 13. The clamping top groove 14 and the clamping slot 15 cooperate with each other. This utility model clamps and fixes both ends of the rod material by cooperating with the clamping top groove 14 and the clamping slot 15, thereby preventing the rod material from sliding during the extrusion process.

[0026] In one instance of this embodiment, please refer to Figures 1-3 The lifting assembly includes a hydraulic lifting pump 16 fixedly connected to the base 1. A bracket 17 is fixedly connected to the output shaft of the hydraulic lifting pump 16. The lifting assembly places the bar material through the bracket 17 and drives the bracket 17 to rise and fall through the hydraulic lifting pump 16. In turn, the bracket 17 drives the bar material to rise and fall, thereby lifting the bar material to the extrusion rod 13 and the extrusion die 5. The extrusion rod 13 and the extrusion die 5 clamp and fix the bar material. After clamping, the hydraulic lifting pump 16 drives the bracket 17 to fall, thereby disengaging the bracket 17 from the extrusion rod 13 and the extrusion die 5.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
