[0002] With the increasing application of aluminum profiles, the usage is increasing, especially in transportation vehicles. Now more and more requirements are placed on the accuracy of the shape and size of aluminum profiles and the uniformity of various properties in the length direction, so the preparation process of aluminum profiles becomes extremely important; if the conventional extrusion method is used, if the temperature is too high, the surface of the aluminum profile will not meet the requirements, and if the temperature is too low, the mechanical properties of the material will be affected. Since high value-added products have very high requirements, in order to meet the requirements of high precision and high surface size of industrial materials, the temperature of the extrusion barrel is required to be relatively high, so that the high precision and high surface size of the profile surface can be maintained during extrusion.

[0003] Existing aluminum profile extrusion dies usually use a cylinder or hydraulic cylinder as the power for extrusion during extrusion molding. The running stroke and movement speed of a single cylinder or hydraulic cylinder are fixed. When extrusion at different speeds is required, this requirement cannot be met. Utility Model Content

[0036] When extruding an aluminum profile, the first hydraulic cylinder 12 drives the first movable plate 2 to quickly move along the length direction of the guide column 10 to approach the extrusion die 3 through the lateral movement of the first drive shaft 13. When the extrusion seat 31 located between the second movable plate 21 and the extrusion die 3 approaches the extrusion die 3, the second hydraulic cylinder 27 works and the extension speed is reduced. The material can be extruded from the extrusion die 3 by the extrusion seat 31 constantly approaching the extrusion die 3. After the extrusion is completed, the first hydraulic cylinder 12 can quickly drive the first movable plate 2 and the second movable plate 21 away from the extrusion die 3. Compared with the slow movement of a traditional single hydraulic cylinder, the efficiency is greatly improved.

[0037] A guide sleeve 22 is installed between the first movable plate 2 and the second movable plate 21. The guide sleeve 22 is slidably matched with the guide column 10. The guide sleeve 22 and the guide column 10 are coaxially aligned. When the first hydraulic cylinder 12 drives the first movable plate 2 to move horizontally, the second movable plate 21 moves at the same time, ensuring the consistency of movement and further improving the structural stability.

[0038] A support seat 16 is arranged under the mounting plate 1, and an upright support column 17 is installed on the support seat 16. An elastic support sleeve 18 is nested in the support column 17, and the elastic support sleeve 18 can be a compression spring. A transverse block 19 is installed transversely on the mounting plate 1, and the top of the elastic support sleeve 18 is connected to the transverse block 19; when vibration occurs, the elastic support sleeve 18 can reduce the impact of the vibration.

[0039] The first driving hole 11 is installed with a circular plate 14, which is fixedly connected to the mounting plate 1. The first hydraulic cylinder 12 is installed on the circular plate 14. The circular plate 14 is also provided with an L-shaped block 15 for positioning the first hydraulic cylinder 12. The L-shaped blocks 15 are respectively arranged at two opposite corners of the first hydraulic cylinder 12. The cylinder body of the first hydraulic cylinder 12 can be fixed in the circular plate 14 through the two L-shaped blocks 15 to prevent it from shifting during operation.

[0040] The first movable plate 2 is installed with a guide block 23, and the guide block 23 is installed with multiple guide rods 24. The mounting plate 1 and the circular plate 14 are both provided with movable holes 25 that are coaxially aligned with the guide rods 24 and for the guide rods 24 to move through. When the first hydraulic cylinder 12 drives the first movable plate 2 to move along the length direction of the guide column 10, the guide rods 24 installed on the first movable plate 2 will slide and cooperate with the circular plate 14 and the movable holes 25 of the mounting plate 1 accordingly, thereby further improving the movement stability of the first movable plate 2.

[0041] The second movable plate 21 is formed with a mounting groove 26 for mounting the second hydraulic cylinder 27. The cylinder body of the second hydraulic cylinder 27 is mounted in the mounting groove 26 by bolts. The driving end of the second hydraulic cylinder 27 faces the first movable plate 2. A connecting plate 32 is arranged between the first movable plate 2 and the second movable plate 21. The driving end of the second hydraulic cylinder 27 is connected to the connecting plate 32. The second movable plate 21 is provided with a second driving hole 29. A second driving shaft 28 is movably passed through the second driving hole 29. One end of the second driving shaft 28 is connected to the connecting plate 32, and the other end of the second driving shaft 28 is connected to the extrusion seat 31. When the second hydraulic cylinder 27 is working, it drives the connecting plate 32 to move laterally. At the same time, the second driving shaft 28 installed on the connecting plate 32 will pass through the second driving hole 29 to drive the extrusion seat 31 on the other side of the second movable plate 21 to move laterally closer to or away from the extrusion die 3.

[0042] The number of the second drive shafts 28 and the second drive holes 29 are both four, and the second drive shafts 28 are respectively arranged on the periphery of the second hydraulic cylinder 27. The plurality of second drive shafts 28 and the second drive holes 29 are slidably matched to improve the movement stability of the extrusion seat 31, and the extrusion is more stable.

[0043] The extrusion die 3 includes a die plate 33 installed at the other end of the guide column 10 and an extrusion sleeve 36 connected to the die plate 33. The wall of the extrusion sleeve 36 is formed with a cooling cavity 37. The cooling cavity 37 is close to the discharge port of the extrusion sleeve 36. The outer wall of the extrusion sleeve 36 is formed with a liquid inlet 38 and a liquid outlet 39 connected to the cooling cavity 37. During extrusion, coolant is introduced into the cooling cavity 37 through the liquid inlet 38 and discharged through the liquid outlet 39. The temperature during extrusion is reduced, the aluminum profile is formed faster, the stability of the aluminum profile after forming can be reduced, and the aluminum profile is convenient for rapid forming.

[0044] Specifically, the mold plate 33 is formed with an extrusion groove 34 for filling materials, and the extrusion groove 34 is formed with an extrusion hole 35 coaxially connected to the extrusion sleeve 36. The material to be extruded is filled into the extrusion groove 34, and then the extrusion seat 31 is close to the extrusion groove 34, and the material passes into the extrusion sleeve 36 from the extrusion hole 35. After entering the extrusion sleeve 36, the material forms an aluminum profile with a shape.

[0045] The extrusion die 3 also includes a die support plate 40 for supporting the extrusion sleeve 36. A die support seat 41 is installed on the top of the die support plate 40. A mounting hole 42 for inserting the extrusion sleeve 36 is formed on the top of the die support seat 41. The die support seat 41 cooperates with the extrusion sleeve 36 through the mounting hole 42 to fix the extrusion sleeve 36, prevent the extrusion sleeve 36 from shifting, and improve the support stability.

[0046] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.
