Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aluminum profile shaping machines, specifically an aluminum profile shaping machine. Background Technology
[0002] During the cooling process after hot extrusion, aluminum profiles will generate residual stress due to complex cross-sectional shapes, uneven wall thicknesses, and inconsistent cooling rates. This causes the profiles to bend, twist, become uneven, or have incorrect angles. Therefore, a straightening machine is needed to straighten, twist, flatten, correct angles, and shape the aluminum profiles.
[0003] In existing technologies, roller straightening is commonly used when shaping aluminum profiles. This method utilizes vertically distributed straightening rollers to apply stress to the profile, causing it to undergo plastic deformation and eliminating existing bends and unevenness. However, in practical applications, when shaping thinner aluminum profiles, if the pressure between the upper and lower rollers is too high, it can easily lead to indentations on the profile surface. Therefore, it is necessary to develop an improved aluminum profile shaping machine to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide an aluminum profile shaping machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum profile shaping machine, comprising a shaping machine body, a threaded rod for adjusting the shaping spacing, and a lifting block for raising and lowering the position. Rotating rollers rotating in opposite directions are rotatably mounted on the front of the shaping machine body and the front of the lifting block. A shaping protection mechanism is provided on the outside of the rotating rollers.
[0006] Preferably, the shaping and protection mechanism includes a straightening roller disposed outside the rotating roller. The straightening roller has a block-shaped groove and a strip-shaped groove inside. A partition is fixedly installed inside the central groove of the straightening roller. A limit ring is fixedly installed outside the straightening roller. An elastic bushing is fitted outside the limit ring. A positioning insert is fixedly installed at the end of the elastic bushing. A stud plate is slidably installed inside the strip-shaped groove. A nut is threaded onto the outside of the stud plate.
[0007] Preferably, two nuts are provided, and the two nuts are symmetrically distributed at the outlet inside the block-shaped groove.
[0008] Preferably, there are two positioning plates, and both positioning plates are in sliding contact with the inner wall surface on the opposite side of the straightening roller and the partition.
[0009] Preferably, holes are provided at corresponding positions of the straightening roller, partition, and positioning plate and the stud plate, and the stud plate slides through the holes provided inside the straightening roller, partition, and positioning plate.
[0010] Preferably, the elastic bushing has a mating groove inside, and the limiting ring is fitted into the mating groove inside the elastic bushing.
[0011] Compared with the prior art, this utility model provides an aluminum profile shaping machine, which has the following beneficial effects:
[0012] 1. This aluminum profile forming machine, through its forming protection mechanism, utilizes an elastic bushing installed on the outside of the straightening rollers to protect the structure of the straightening rollers during use. This prevents indentations caused by excessive pressure when forming thin aluminum profiles. Furthermore, the removable elastic bushing allows it to be used as a separate accessory, enabling it to be replaced individually without increasing operating costs if damaged.
[0013] 2. This aluminum profile forming machine uses a mating groove inside the elastic bushing to engage with a limiting ring, which can limit the elastic bushing and prevent it from shifting during use, thus ensuring the stability of the forming process. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0022] Example:
[0023] Please see Figure 1-4 This utility model provides a technical solution: an aluminum profile shaping machine, including a shaping machine body 1, a threaded rod 3 for adjusting the shaping spacing, and a lifting block 4 for lifting position. Rotating rollers 5 that rotate in opposite directions are rotatably installed on the front of the shaping machine body 1 and the front of the lifting block 4. A shaping protection mechanism 2 is provided on the outside of the rotating rollers 5.
[0024] Furthermore, the shaping and protection mechanism 2 includes a straightening roller 21, which is disposed outside the rotating roller 5. The straightening roller 21 has a block groove 22 and a strip groove 23 inside. A partition plate 24 is fixedly installed inside the central groove of the straightening roller 21. A limit ring 25 is fixedly installed outside the straightening roller 21. An elastic bushing 26 is fitted outside the limit ring 25. A positioning insert plate 27 is fixedly installed at the end of the elastic bushing 26. A stud plate 28 is slidably installed inside the strip groove 23. A nut 29 is threaded on the outside of the stud plate 28. Through the shaping and protection mechanism 2, the elastic bushing 26 can be assembled and installed on the outside of the assemblable straightening roller 21. The elastic bushing 26 has a certain elasticity to protect the surface of the shaped profile and prevent it from being indented.
[0025] Furthermore, there are two nuts 29, and the two nuts 29 are symmetrically distributed at the outlet inside the block groove 22. The symmetrical distribution of the nuts 29 at the outlet of the block groove 22 facilitates installation and disassembly, avoiding the inconvenience of disassembling the nuts 29.
[0026] Furthermore, two positioning plates 27 are provided, and both positioning plates 27 slide in contact with the inner wall surface of the straightening roller 21 and the partition plate 24 on the opposite side. The positioning plates 27 inserted by sliding positioning can assist in the positioning and fixing of the elastic bushing 26.
[0027] Furthermore, holes are provided at corresponding positions of the straightening roller 21, partition 24, and positioning insert 27 and the stud plate 28, and the stud plate 28 slides through the holes provided inside the straightening roller 21, partition 24, and positioning insert 27. By utilizing the sliding passage of the stud plate 28, the stud plate 28 can limit the positioning insert 27 and fix the elastic bushing 26.
[0028] Furthermore, the elastic bushing 26 has a mating groove inside, and the limiting ring 25 is fitted into the mating groove inside the elastic bushing 26. By using the mating groove, the elastic bushing 26 can be longitudinally limited to prevent it from sliding and shifting during shaping.
[0029] In actual operation, when this device is used, after the mating groove inside the elastic bushing 26 is fitted with the limiting ring 25, one positioning plate 27 is inserted into the inside of the straightening roller 21 and the partition plate 24, and the other positioning plate 27 is pulled so that the elastic bushing 26 stretches out a little due to its elasticity. Then, the other positioning plate 27 is also inserted into the inside of the straightening roller 21 and the partition plate 24. The stud plate 28 is slid so that it is inserted into the inside of the two positioning plates 27. The stud plate 28 can then be fixed with the nut 29. After fixing, the straightening roller 21 can be installed on the outside of the rotating roller 5. When shaping thinner aluminum profiles, the elastic bushing 26 can effectively protect the profile and avoid indentation caused by excessive pressure.
[0030] It should be noted that the installation method of mounting the straightening roller 21 to the outside of the rotating roller 5 adopts existing technology. The straightening roller 21 and the rotating roller 5 can be installed by cold pressing through an interference fit. The two opposing rotating rollers 5 rotate in opposite directions. The rotation is achieved by the main motor, using a gearbox, universal coupling, transfer gearbox and roller drive shaft. The shaping and protection mechanism 2 can be assembled on different rotating rollers 5 according to actual needs.
[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
