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.
[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example
[0020] Please see Figure 1 As shown, this utility model provides an extrusion press for producing seamless aluminum tubes, including a drive device 1, a frame 2 fixedly installed at the bottom of the drive device 1, an extrusion chamber 3 fixedly installed on the right side of the top of the frame 2, the interior of the extrusion chamber 3 being connected to the drive device 1, a feed hopper 4 connected to the left side of the top of the extrusion chamber 3, a support seat 5 movably installed on the lower right side of the extrusion chamber 3, fixed plates 6 fixedly installed on both the front and rear sides of the front of the extrusion chamber 3, a slide rail 7 installed on the surface of the fixed plate 6, a slide plate 8 slidably installed on the outside of the slide rail 7, an adjustment knob 9 movably installed on the left end of the outside of the slide plate 8, and a fixed box 10 fixedly installed on the right side of the slide plate 8, the fixed box 10 being located at the front and rear ends of the support seat 5.
[0021] This technical solution allows for convenient horizontal adjustment of the fixed box 10 by setting up slide rail 7, slide plate 8, and adjustment knob 9, thereby adjusting the horizontal position of the bearing seat 5 so that it can better correspond to the discharge port of the extrusion box 3 and adapt to the extrusion production needs of aluminum tubes of different specifications. By using the cooperation of moving groove 11, moving slider 12, positioning rod 13, limit spring 14, and lifting adjustment plate 15, the height of the bearing seat 5 can be flexibly adjusted. By pulling the lifting adjustment plate 15 upward, the limit spring 14 is compressed, and the positioning rod 13 is disengaged from the moving slider 12, so that the bearing seat 5 can be moved up and down. After adjusting to a suitable height, the lifting adjustment plate 15 is released, and the positioning rod 13 is inserted into the positioning hole of the moving slider 12 under the action of the limit spring 14 to achieve the positioning of the bearing seat 5. The operation is simple and convenient. Example
[0022] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, the fixed box 10 has vertically opened moving grooves 11 on both the front and rear sides. A moving slider 12 is slidably connected inside the moving groove 11. The inner side of the moving slider 12 is connected to the end of the bearing seat 5. A positioning rod 13 is inserted and installed inside the moving slider 12.
[0023] Adopting such Figure 1 The technical solution shown allows the carrier seat 5 to slide vertically through the cooperation of the moving groove 11 and the moving slider 12, thereby achieving height adjustment. By pulling the positioning rod 13 upward, the carrier seat 5 can move freely up and down within the moving groove 11 to adapt to the bearing height requirements of different specifications or different production needs, greatly improving the flexibility and versatility of the equipment. The positioning rod 13 can be accurately inserted into the positioning hole in the moving slider 12 after the carrier seat 5 is adjusted to a suitable height, fixing the carrier seat 5 in the corresponding position. This positioning method is relatively accurate and can ensure that the carrier seat 5 will not easily move up and down during use, ensuring the stability of the equipment operation. For the production process of seamless aluminum tubes, a stable carrier seat 5 helps to improve product quality and avoid damage to the aluminum tube or production deviations caused by the shaking of the carrier seat 5.
[0024] Secondly, in the technical solution, a limiting spring 14 is sleeved on the outer end of the positioning rod 13, and a lifting adjustment plate 15 is fixedly installed on the inner end of the limiting spring 14. The lifting adjustment plate 15 is attached to the outside of the fixed box 10, and both ends are slidably installed on the outside of the fixed box 10 through guide rods 16. The right end of the lifting adjustment plate 15 is designed with a bend, and a locking knob 17 is movably installed on the outside of the bend part of the right end of the lifting adjustment plate 15. The locking end of the locking knob 17 is fastened to the right side of the fixed box 10.
[0025] Its adoption is as follows Figure 1The technical solution shown provides a stable sliding track for the lifting adjustment plate 15, ensuring that the lifting adjustment plate 15 will not shake or shift during sliding. This ensures that the positioning rod 13 can be accurately inserted into the positioning hole, enhancing the stability and reliability of the entire structure. This allows the bearing seat 5 to remain stable during operation, preventing loosening or displacement due to inaccurate positioning, thus ensuring the stability of the seamless aluminum tube production process and product quality. The bent design on the right end of the lifting adjustment plate 15 and the movable locking knob 17 provide additional safety for the positioning of the bearing seat 5. After initial positioning is achieved through the limit spring 14 and the positioning rod 13, if there is significant vibration or other interference in the working environment, the positioning rod 13 may become loose. In this case, by tightening the locking knob 17, the lifting adjustment plate 15 can be firmly fixed to the right side of the fixed box 10, further locking the position of the positioning rod 13 and preventing it from being accidentally pulled out. This ensures that the bearing seat 5 remains stable under various working conditions, improving the safety and reliability of the equipment. Example
[0026] This utility model is as follows Figures 1-4 As shown, the interior of the bearing seat 5 is arc-shaped and matches the discharge hole on the right side of the fixed box 10. The bearing seat 5 has auxiliary placement grooves 18 on both the front and rear sides of the top. The bearing seat 5 consists of two parts, and the connecting part of the right part of the bearing seat 5 is equipped with a connecting slide rod.
[0027] Using the above technical solution, the auxiliary placement slots 18 opened on the front and rear sides of the top of the support seat 5 provide additional support points for the seamless aluminum tube placed on the support seat 5, and can also insert baffles inside to provide auxiliary shielding for the aluminum tube. The support seat 5 is composed of two parts, and the right part of the support seat 5 is equipped with a connecting slide rod. This structure makes the installation and disassembly of the support seat 5 more convenient and quick. The two parts of the support seat 5 can be easily separated or combined through the connecting slide rod, which can increase the bearing area of the top of the support seat 5 and save installation and disassembly time.
[0028] The working principle of this utility model is as follows: the drive device 1 is started to provide power for the entire extruder. The aluminum raw material enters the extrusion box 3 through the feed hopper 4. In the extrusion box 3, the drive device 1 applies pressure to the aluminum raw material, so that it is extruded into a seamless aluminum tube under the action of a specific mold. The extruded seamless aluminum tube is discharged from the discharge port on the right side of the extrusion box 3.
[0029] When it is necessary to adjust the horizontal position of the support seat 5, the operator rotates the adjustment knob 9 on the left side of the outside of the slide plate 8. The adjustment knob 9 loosens the fixation of the slide plate 8, and the slide plate 8 can slide freely on the slide rail 7 on the surface of the fixed plate 6. After the operator slides the slide plate 8 to the appropriate position, the operator rotates the adjustment knob 9 again to fix the slide plate 8 on the slide rail 7. Since the fixed box 10 is fixedly installed on the right side of the slide plate 8 and the support seat 5 is connected to the fixed box 10, the change in the position of the slide plate 8 drives the adjustment of the horizontal position of the support seat 5.
[0030] To adjust the height of the support seat 5, the operator first pulls the positioning rod 13, causing one end to move out of the inside of the movable slider 12. At this time, the support seat 5, connected to the movable slider 12, can slide freely up and down within the movable slots 11 on both sides of the fixed box 10. When the support seat 5 moves to the appropriate height, the operator moves the lifting adjustment plate 15 and aligns it with the positioning hole inside the movable slider 12. Then, the limit on the positioning rod 13 is released, and the limit spring 14 returns to its original position, causing the positioning rod 13 to re-insert into the positioning hole of the movable slider 12, thus completing the height adjustment of the support seat 5. For positioning, the operator can also tighten the locking knob 17 on the right bent part of the lifting adjustment plate 15 to further fix the lifting adjustment plate 15 to the right side of the fixed box 10, ensuring that the height of the bearing seat 5 will not change. The internal arc structure of the bearing seat 5, after adjusting its position and height, fits the shape of the seamless aluminum tube extruded from the outlet of the extrusion box 3, and can stably support the aluminum tube. At the same time, the auxiliary placement slots 18 on the front and rear sides of the top of the bearing seat 5 can place auxiliary baffles to hold part of the aluminum tube, further restricting the movement of the aluminum tube and improving the stability of the aluminum tube placement.
