Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile processing, in particular to an aluminum profile extrusion device with uniform heat dissipation. Background Art

[0002] Aluminum profile refers to a profile with a specific cross-sectional shape processed from aluminum billets through an extrusion process. Due to the characteristics of aluminum profiles such as light weight, corrosion resistance, strong plasticity, good thermal conductivity, beautiful appearance, environmental protection, and high strength, they are widely used in construction, transportation, electronics, machinery manufacturing, aerospace and other fields.

[0003] The production of aluminum profiles includes the steps of smelting, casting, heating, extrusion, cooling, cutting, and surface treatment. During the extrusion step, an aluminum profile extrusion device is usually used to process the aluminum billet heated to an appropriate temperature. The aluminum billet is fed into the extrusion barrel, and the extrusion rod is pushed forward to apply pressure to the aluminum billet so that it passes through the die hole of the mold to form an aluminum profile with a specific cross-sectional shape, which is convenient for practical application.

[0004] However, the existing aluminum profile extrusion device may have the following problems during use:

[0005] During the extrusion process of aluminum billets, the mold is in direct contact with the high-temperature aluminum billet and will quickly absorb heat. The mold will overheat, causing the mold material to soften and the hardness to decrease. The mold will also expand at high temperatures, resulting in deviations in the size of the extruded product, reducing the dimensional accuracy of the aluminum profile, deteriorating the surface quality, and even causing warping and deformation, which will affect the quality of the final product.

[0006] In addition, the mold will also generate thermal stress under the action of high temperature and high pressure. These stresses exceed the bearing limit of the mold material and will cause the mold to crack or break, resulting in defects on the surface of the extruded product, such as cracks, bubbles, etc., and shortening the service life of the mold. At the same time, overheated molds may cause safety risks such as burns to operators and may also cause serious accidents such as fire.

[0007] Therefore, the present invention proposes an aluminum profile extrusion device with uniform heat dissipation to make up for and improve the deficiencies of the prior art. Summary of the invention

[0020] (III) Beneficial effects

[0021] The aluminum profile extrusion device with uniform heat dissipation provided by the present invention has the following beneficial effects:

[0022] 1. By meshing the meshing teeth connected to the swivel with the gear, when the gear rotates during use, it drives the spray pipe connected to the swivel through the sliding column to rotate. When the spray pipe rotates, the coolant is evenly sprayed to the outer surface of the mold around the circle to ensure that all parts of the mold surface can be fully cooled, thereby improving the heat dissipation efficiency and avoiding local overheating caused by the lack of coolant spraying on the local surface of the mold, which in turn causes the performance of the mold material to deteriorate, resulting in thermal fatigue and cracks. Spraying the coolant evenly on the mold surface can make the temperature in the extrusion process more stable, maintain the consistency of the production process, ensure the dimensional accuracy and surface quality of the extruded aluminum profile, reduce warping and deformation, thereby improving the quality of the final product, reducing the thermal deformation of the aluminum profile caused by overheating of the mold during the extrusion process, improving the dimensional accuracy and surface quality of the product, reducing the scrap rate, reducing the thermal fatigue and wear of the mold, extending the service life of the mold, and reducing the cost of mold replacement.

[0023] 2. The mold is fixed by inserting the fixing block into the fixing groove opened on the surface of the mold. When in use, the mold with different mold holes can be quickly replaced according to different production needs to produce aluminum profiles of various specifications and shapes to meet the diverse needs of the market and improve the flexibility and adaptability of the production line. The mold is positioned by inserting the plug-in block connected to the mold into the limiting groove, which can reduce the adjustment time of the mold when replacing the mold, thereby reducing the time required for replacing the mold, thereby reducing the downtime of the production line, and can improve the accuracy of mold replacement and installation, reduce safety hazards during mold replacement, and improve the safety of operators when replacing and installing molds.

[0024] 3. By connecting the spring 1 connected to the extrusion head with the extrusion rod, when the aluminum billet is extruded, the spring 1 can absorb the impact force generated by the flow of the aluminum billet after extrusion, reduce the direct impact on the extrusion head, and thus protect these key components from damage. The elasticity of the spring 1 can provide a buffer for the extrusion process, help to smoothly transmit force and control the extrusion speed, and reduce defects in the extruded aluminum profiles due to sudden force changes. The spring 1 can also disperse and absorb part of the stress, reduce the mechanical stress concentration on the extrusion head during extrusion, and reduce the risk of fatigue damage. Since the spring 1 is distributed in a circular array with the center point of the extrusion cylinder as a reference, the stability of the extrusion rod when extruding the aluminum billet through the extrusion head can be improved, and the deviation or tilt that may be caused by single-point connection can be reduced, thereby ensuring the reliability of extrusion.

[0025] 4. Through the filter plate arranged inside the collection area, when in use, the filter plate will filter the used coolant and collect it inside the collection area, so that the coolant collected in the collection area can be reused after being processed, reducing the consumption of coolant, while reducing the discharge of waste liquid, avoiding the harmful substances that may be contained in the coolant, and avoiding direct discharge, which will cause harm to the soil, water sources, etc. Since the filter plate is inclined and the lower surface of the filter plate is connected to the inner wall of the collection area through spring three, when the rotating ring drives the push block to rotate, the push block squeezes the filter plate downward through the push rod, and the spring three connected to the filter plate is compressed and stores a certain amount of elastic potential energy. When the push block no longer passes When the push rod presses the filter plate downward, the elastic potential energy stored in spring three is released, and drives the filter plate connected thereto to vibrate to a certain extent. Since the filter plate is set at an angle, when spring three drives the filter plate to vibrate, the impurities intercepted on the surface of the filter plate move to the side with lower height on the surface of the filter plate, so that the impurities intercepted by the filter plate are concentrated on the side with lower height on the upper surface of the filter plate, so that the operator can remove them more easily, reducing the cleaning time and workload. In addition, the vibration of the filter plate driven by spring three can avoid the accumulation of impurities on the upper surface of the filter plate, so that the filter plate can more effectively filter the impurities in the coolant after use, reduce the risk of filter plate clogging, and keep the filter plate unobstructed.

[0047] A baffle 35 is detachably connected to the upper surface of the machine tool 1 and located at the straight groove of the machine tool 1. The baffle 35 can prevent the coolant from splashing onto the surface of the mold 21 and causing harm to the operator, such as burns, splashing into the eyes, etc., thereby protecting the safety of the operator.

[0048] The following is the entire working process and working principle of the above embodiment:

[0049] Before use, select the appropriate aluminum billet, cut it into the required length, put it into the heating furnace and heat it to the extrusion temperature, and check the cooling system to ensure it is working properly.

[0050] Next, according to production requirements, a mold 21 with corresponding mold holes is selected, and the plug-in block 20 fixedly connected to the mold 21 is plugged into the limiting groove 19 provided on one side of the extrusion cylinder 2, and the adjusting plate 25 is rotated clockwise. When the adjusting plate 25 rotates, the clamping block 29 connected to the adjusting plate 25 through the second spring 28 is driven to rotate, and the elastic force of the second spring 28 pushes the clamping block 29 to be clamped into the clamping groove 30 uniformly provided on the surface of the corresponding fixing ring 3, thereby fixing the rotated adjusting plate 25. At the same time, when the adjusting plate 25 rotates clockwise, the inclined groove 26 provided on the surface of the adjusting plate 25 is driven to rotate clockwise. When the inclined groove 26 rotates clockwise, the fixing block 24 fixedly connected to the second connecting column 23 is pushed through the second connecting column 23 to be plugged into the fixing groove 22 provided on the surface of the mold 21, thereby fixing the mold 21.

[0051] Through the above structure, according to different production needs, the mold 21 with different mold holes can be quickly replaced to produce aluminum profiles of various specifications and shapes, meet the diverse needs of the market, and improve the flexibility and adaptability of the production line. The mold 21 is positioned by inserting the plug-in block 20 connected to the mold 21 into the limiting groove 19. The limiting groove 19 and the plug-in block 20 can provide a fixed reference for the mold 21 during installation, ensuring that the mold 21 can be accurately aligned with the horizontal center line position of the extrusion cylinder 2 during installation, thereby reducing the adjustment time of the mold 21 when replacing the mold 21, thereby reducing the time required for replacing the mold 21, thereby reducing the downtime of the production line. In addition, since the position of the limiting groove 19 is fixed, each replacement and installation of the mold 21 is based on the same positioning, thereby improving the accuracy of the replacement and installation of the mold 21, and quickly installing the mold 21 in the same way each time, which can reduce the safety hazards caused to the operator by the complexity of the operation when replacing the mold 21, and improve the safety of the operator when replacing and installing the mold 21.

[0052] When in use, first, the heated aluminum billet is fed into the extrusion barrel 2, and the extruder is started. The extruder drives the extrusion rod 14 to move in the direction close to the die 21. When the extrusion rod 14 moves, the spring 13 connected thereto drives the extrusion head 12 to move in the direction close to the die 21. When the extrusion head 12 moves, pressure is applied to the heated aluminum billet in the extrusion barrel 2, so that the aluminum billet passes through the die hole opened on the surface of the die 21 to form an aluminum profile with a specific cross-sectional shape. Since the extrusion rod 14 is connected to the extrusion head 12 through the springs 13 distributed in a circular array with the center point of the extrusion barrel 2 as a reference, when the extruder drives the extrusion head 12 to move in the direction close to the die 21 to extrude the aluminum billet through the extrusion rod 14, the spring 13 can The spring 13 can absorb the impact force generated by the flow of the aluminum billet after extrusion, reduce the direct impact on the extrusion head 12, and thus protect these key components from damage. The elasticity of the spring 13 can provide a buffer for the extrusion process, help to smoothly transmit force and control the extrusion speed, and reduce the defects of the extruded aluminum profiles due to sudden force changes. The spring 13 can also disperse and absorb part of the stress, reduce the mechanical stress concentration on the extrusion rod 14 on the extrusion head 12 during extrusion, and reduce the risk of fatigue damage. Since the spring 13 is distributed in a circular array with the center point of the extrusion cylinder 2 as a reference, the stability of the extrusion rod 14 when extruding the aluminum billet through the extrusion head 12 can be improved, and the deviation or tilt that may be caused by the single-point connection can be reduced, thereby ensuring the reliability of the extrusion.

[0053] Next, when the extrusion rod 14 moves in the direction close to the mold 21, the extrusion rod 14 drives the auxiliary rod 17 fixedly connected thereto to move in the direction close to the mold 21. Since the end of the auxiliary rod 17 away from the extrusion rod 14 is slidably connected to the inside of the spiral chute 16 provided on the surface of the rotating shaft 15, when the auxiliary rod 17 moves, it drives the rotating shaft 15 to rotate. When the rotating shaft 15 rotates, it drives the connecting column 18 fixedly connected to the rotating shaft 15 to rotate. When the connecting column 18 rotates, it drives the gear 11 fixedly connected thereto. When the gear 11 rotates, the meshing teeth fixedly connected to the swivel 10 drive the swivel 10 to rotate. When the swivel 10 rotates, the spray pipe 7 fixedly connected to it through the slide column 6 drives the spray pipe 7 to rotate. At the same time, the coolant inside the storage area 401 is transported to the inside of the spray pipe 7 through the delivery pipe 8, and then sprayed to the outer surface of the mold 21 through the spray holes evenly opened on the surface of the spray pipe 7. Therefore, the spray pipe 7 evenly sprays the coolant to the outer surface of the mold 21 around the periphery, ensuring that all parts of the surface of the mold 21 can be fully cooled. Thereby, the heat dissipation efficiency is improved, and local overheating caused by the local surface of the mold 21 not being sprayed with coolant is avoided, which in turn causes the material performance of the mold 21 to deteriorate, resulting in thermal fatigue and cracks. Spraying the coolant evenly on the surface of the mold 21 can make the temperature in the extrusion process more stable, maintain the consistency of the production process, ensure the dimensional accuracy and surface quality of the extruded aluminum profile, reduce warping and deformation, thereby improving the quality of the final product, reducing the thermal deformation of the aluminum profile caused by overheating of the mold during the extrusion process, improving the dimensional accuracy and surface quality of the product, reducing the scrap rate, reducing the thermal fatigue and wear of the mold 21, extending the service life of the mold 21, and reducing the cost of replacing the mold 21. At the same time, the extrusion rod 14 is used to drive the sliding column 6 connected to the spraying pipe 7 to rotate through the auxiliary rod 17, so that the coolant sprayed to the outer surface of the mold 21 is consistent with the extrusion process of the aluminum billet, and the automatic cooling of the mold 21 can be realized during the extrusion process, reducing manual intervention, and avoiding deformation of the extruded aluminum profile due to temperature fluctuations of the mold 21 during manual operation, thereby improving the reliability of the equipment.

[0054] Finally, the coolant sprayed on the outer surface of the mold 21 will flow to the inside of the collection area 402 through the straight groove opened on the upper surface of the machine tool 1. Since the filter plate 32 is provided inside the collection area 402, the used coolant will be filtered by the filter plate 32 before flowing to the inside of the collection area 402, so that the coolant collected in the collection area 402 can be reused after being processed, thereby reducing the consumption of coolant and reducing the discharge of waste liquid, avoiding the direct discharge of harmful substances that may be contained in the coolant, which will cause harm to the soil, water sources, etc.;

[0055] Furthermore, when the swivel 10 rotates, it drives the push block 31 fixedly connected to the swivel 10 to rotate. Since the push rod 34 and the push block 31 are located in the same vertical section, when the swivel 10 drives the push block 31 to rotate to the push rod 34, the push block 31 presses the filter plate 32 downward through the push rod 34. At this time, the spring three 33 connected to the filter plate 32 is compressed and stores a certain amount of elastic potential energy. The swivel 10 continues to drive the push block 31 to rotate, and the push block 31 no longer presses the filter plate 32 downward through the push rod 34. The elastic potential energy stored in the spring three 33 is released, and drives the filter plate 32 connected thereto to generate a The filter plate 32 is tilted so that when the spring 33 drives the filter plate 32 to vibrate, the impurities intercepted on the surface of the filter plate 32 move to the side with a lower height on the surface of the filter plate 32, so that the impurities intercepted by the filter plate 32 are concentrated on the side with a lower height on the upper surface of the filter plate 32, so that the operator can remove them more easily, reducing the cleaning time and workload, and the spring 33 drives the filter plate 32 to vibrate to avoid the accumulation of impurities on the upper surface of the filter plate 32, so that the filter plate 32 can more effectively filter the impurities in the coolant after use, reduce the risk of clogging the filter plate 32, and keep the filter plate 32 unobstructed.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
