Description

Technical Field

[0001] This utility model relates to the field of aluminum flat tube production and processing technology, specifically to an aluminum flat tube extrusion equipment. Background Technology

[0002] Aluminum flat tubes are a type of long tubing that is widely used in building decoration, solar power generation supports, glass curtain wall supports, highway guardrails, and other fields. During production, aluminum flat tubes are usually formed by extrusion. A hydraulic cylinder is used to push the aluminum round tube into the forming mold, and the flexibility and ductility of aluminum material are used to form the aluminum flat tube. CN222607584U discloses an extrusion equipment for producing aluminum flat tubes. The aluminum round tube material to be extruded is placed on an aluminum rod support, the extrusion equipment is started, and the aluminum round tube is extruded into the forming die by a guiding component. However, it has two problems: 1. The hydraulic cylinder lacks a fixing structure for the aluminum round tube, which makes the aluminum round tube easy to tilt during extrusion, resulting in the flat tube after forming not being straight enough and the thickness distribution of the flat tube being uneven; 2. The guiding component cannot be raised and lowered according to the diameter of the aluminum round tube to be extruded, and has no guiding effect on round tubes with smaller diameters. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, such as the easy movement of the tail end of the aluminum round tube and the inability of the guiding components to guide round tubes of different diameters, this utility model proposes an aluminum flat tube extrusion equipment.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an aluminum flat tube production extrusion equipment, including a base body, a hydraulic cylinder installed on the base body, an aluminum round tube fixing mechanism fixedly installed on the piston end of the hydraulic cylinder, and an aluminum flat tube forming mechanism installed on the base body, and a support and guide mechanism provided in the middle of the base body. The support and guide mechanism includes a sleeve welded and fixed to the upper end of the base body. A threaded rod is threadedly connected to the upper end of the sleeve. A support ring is rotatably connected to the upper end of the threaded rod through a bearing. A guide wheel is rotatably mounted on the upper part of the support ring. A rotating part is integrally formed on the outside of the threaded rod.

[0005] Preferably, the aluminum tube fixing mechanism includes a circular fixing plate, which is fixedly connected to the piston end of the hydraulic cylinder, and six sets of limiting slide grooves arranged in a ring array are provided on one side of the fixing plate, and limiting slide seats are slidably connected in the limiting slide grooves.

[0006] Preferably, a fixing arc plate is integrally formed on the outer side of the limiting slide, a top plate is integrally formed on the outer side of the fixing arc plate, a compression spring is welded to one side of the limiting slide, and the other end of the compression spring is welded and fixed to the limiting slide groove.

[0007] Preferably, the aluminum flat tube forming mechanism includes a forming template integrally formed on the base body, a spherical guide groove is provided on one side of the forming template, and a strip-shaped flat tube forming groove is provided on the other side of the forming template, and the guide groove and the flat tube forming groove are connected.

[0008] Preferably, the support and guide mechanism further includes side columns welded and fixed to the upper end of the base body. Two sets of side columns are symmetrically arranged, and a limiting groove is opened on the inner side of the side column. The side of the support ring is inserted into the limiting groove.

[0009] Preferably, the upper part of the support ring is provided with a mounting groove, and there are 27 sets of mounting grooves arranged in a ring. The guide wheel is rotatably mounted in the mounting groove through a bearing.

[0010] Preferably, the outer wall of the rotating part is provided with anti-slip texture, and the upper end of the sleeve is provided with a threaded connection hole.

[0011] The advantages of this utility model are: This utility model can fix aluminum round tubes of different models through an aluminum round tube fixing mechanism. The fixing arc plate can expand outward under the action of the compression spring, thereby squeezing and generating friction with the inner wall of the aluminum round tube to fix it. The top plate can support the tail of the round tube, achieving the fixing effect. This solves the problem of uneven thickness distribution caused by the shaking of the round tube when it is formed by the aluminum flat tube forming mechanism.

[0012] This invention uses a central support and guide mechanism to support and guide the middle part of the aluminum tube, and the height of the support ring can be raised or lowered by rotating the rotating part, thereby adapting to aluminum tubes of different diameters and solving the problem that the guide assembly cannot be raised or lowered according to the diameter of the aluminum tube to be extruded.

Detailed Implementation

[0016] 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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses an extrusion apparatus for producing aluminum flat tubes. (Refer to...) Figure 1 and Figure 5 An aluminum flat tube extrusion equipment includes a base body 1, a hydraulic cylinder 101 installed on the base body 1, an aluminum round tube fixing mechanism 2 fixedly installed on the piston end of the hydraulic cylinder 101, an aluminum flat tube forming mechanism 3 installed on the base body 1, and a support and guide mechanism 4 provided in the middle of the base body 1. The support and guide mechanism 4 includes a sleeve 401 welded and fixed to the upper end of the base body 1. The upper end of the sleeve 401 is threadedly connected to a threaded rod 402. The upper end of the threaded rod 402 is rotatably connected to a support ring 403 via a bearing. A guide wheel 404 is rotatably mounted on the upper part of the support ring 403. A rotating part 405 is integrally formed on the outside of the threaded rod 402.

[0018] Reference Figure 2 and Figure 3The aluminum tube fixing mechanism 2 includes a circular fixing plate 201. The fixing plate 201 and the piston end of the hydraulic cylinder 101 are fixedly connected by bolts. Six sets of limiting slide grooves 202 arranged in a ring array are opened on one side of the fixing plate 201. Limiting slide seats 203 are slidably connected in the limiting slide grooves 202. Both the limiting slide grooves 202 and the limiting slide seats 203 are T-shaped structures. The limiting slide seats 203 are not easy to fall off the limiting slide grooves 202. Reference Figure 2 and Figure 3 The outer side of the limiting slide 203 is integrally formed with a fixing arc plate 204, and the outer side of the fixing arc plate 204 is integrally formed with a top plate 205. A compression spring 206 is welded to one side of the limiting slide 203, and the other end of the compression spring 206 is welded and fixed to the limiting slide groove 202. The compression spring 206 can open the fixing arc plate 204, thereby generating friction between the fixing arc plate 204 and the inner wall of the aluminum tube to fix it, preventing the aluminum tube from shifting during extrusion. Reference Figure 2 and Figure 4 The aluminum flat tube forming mechanism 3 includes a forming template 301 integrally formed on the base body 1. A spherical guide groove 302 is provided on one side of the forming template 301, and a strip-shaped flat tube forming groove 303 is provided on the other side of the forming template 301. The guide groove 302 and the flat tube forming groove 303 are connected. The aluminum round tube to be extruded is guided through the guide groove 302 of the forming template 301 and enters the flat tube forming groove 303. Under the pressure of the flat tube forming groove 303, it will be extruded into an aluminum flat tube. Reference Figure 2 and Figure 5 The support and guide mechanism 4 also includes a side column 406 welded and fixed to the upper end of the base body 1. Two sets of side columns 406 are symmetrically arranged, and a limiting groove 407 is opened on the inner side of the side column 406. The side of the support ring 403 is inserted into the limiting groove 407. The limiting groove 407 can prevent the support ring 403 from rotating. Reference Figure 2 and Figure 5 The upper part of the support ring 403 is provided with an installation groove 408. There are twenty-seven sets of installation grooves 408 arranged in a ring. The guide wheel 404 is rotatably installed in the installation groove 408 through the bearing. After the height of the support ring 403 is adjusted, the guide wheel 404 abuts against the outer wall of the aluminum tube, which plays a supporting role and prevents the aluminum tube from sinking due to gravity. At the same time, it plays a guiding role and works with the aluminum tube fixing mechanism 2 to prevent the aluminum tube from shifting. Reference Figure 2 and Figure 5The outer wall of the rotating part 405 is provided with anti-slip texture, and the upper end of the sleeve 401 is provided with a threaded connection hole 409. By rotating the rotating part 405, the threaded rod 402 can be extended and retracted, thereby changing the height of the support ring 403, which plays a supporting and guiding role for aluminum round tubes of different diameters.

[0019] Working principle: First, the hydraulic cylinder 101 needs to be controlled to retract. Then, the tail end of the aluminum round tube to be extruded into an aluminum flat tube is inserted into the outside of all the fixed arc plates 204. Then, the hydraulic cylinder 101 is started to push the aluminum round tube into the aluminum flat tube forming mechanism 3. At this time, the hydraulic cylinder 101 needs to be stopped. By rotating the rotating part 405, the threaded rod 402 is extended and retracted to adjust the end center of the aluminum round tube and the spherical shape of the guide groove 302 to be on the same horizontal line. Then, the hydraulic cylinder 101 is started again to completely push the aluminum round tube into the flat tube forming groove 303 along the guide groove 302 to complete the entire forming process. After extruding one aluminum round tube, the hydraulic cylinder 101 retracts and a new aluminum round tube is installed. There is no need to readjust the support guide mechanism 4 to complete the forming again.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
