Description

Technical Field

[0001] This utility model mainly relates to the field of titanium alloy tube surface cleaning technology, specifically to a titanium alloy tube straightening machine. Background Technology

[0002] After annealing, pipes may bend under high temperatures, necessitating the use of a straightening machine to improve their straightness. A straightening machine typically uses hyperbolic rollers to compress the pipe and other materials, altering their straightness. Specifically, it straightens materials of different diameters by changing the angle between the two rollers, with both the upper and lower rollers fixed and supported by a support frame.

[0003] During the straightening process, the titanium alloy tube moves from left to right. As it moves forward, the bent titanium alloy tube may collide with the support frame of the straightening machine. After the collision, the surface of the tube will be scratched, producing titanium shavings and other particles. The rollers or the tube may stick to the detached particles. If they are not cleaned in time, the titanium alloy tube in the later part is prone to pitting during the straightening process, affecting the appearance and resulting in poor tube straightening quality.

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Reference Figures 1 to 4 As shown, this embodiment provides a titanium alloy straightening machine 100. A straightening machine is a device used to straighten tubular metal materials. Its working principle is to plastically deform the titanium alloy tube by applying pressure and heat, restoring it to its original straight shape. Specifically, the straightening machine typically consists of a feeding system, a straightening zone, and a discharge system. First, the titanium alloy tube is fed into the feeding system and enters the straightening zone. The straightening zone typically consists of one or more pairs of rollers arranged vertically, whose spacing and position can be adjusted as needed. When the titanium alloy tube passes through the straightening zone, the pressure and position of the rollers cause it to undergo plastic deformation. The rollers are usually arranged in a specific waveform to better change the shape of the titanium alloy tube. In addition, the straightening machine may also apply a certain amount of heat, such as high-frequency induction heating or flame heating, to help reduce the elastic deformation of the titanium alloy tube.

[0034] During the straightening process, the titanium alloy tube is subjected to the squeezing and stress of the rollers, resulting in plastic deformation and gradually restoring its straight shape. The straightened titanium alloy tube is then conveyed to the next processing stage via a discharge system. Throughout the process, the straightening machine is typically equipped with sensors and control systems to monitor and adjust the movement and pressure of the rollers to ensure optimal straightening results. In summary, the straightening machine uses pressure and heat to plastically deform the titanium alloy tube, restoring it to its original straight shape.

[0035] Figure 3 This is a top view of part of the straightening rollers. Figure 4 This is a front view of part of the straightening rollers. During the straightening process, the straightening rollers can not only rotate around their own axis, but also rotate along the vertical axis. The straightening rollers include an upper straightening roller 5 and a lower straightening roller 6. The center lines of the upper straightening roller 5 and the lower straightening roller 6 can be parallel to each other or intersect each other. In other words, the center lines of adjacent upper straightening rollers or adjacent lower straightening rollers can be set to be parallel to each other or intersect each other.

[0036] Reference Figure 1 As shown, the titanium alloy straightening machine 100 includes a support frame 4, an upper straightening roller 5, and a lower straightening roller 6 mounted on the support frame 4. Each support frame 4 corresponds to one upper straightening roller 5 or one lower straightening roller 6. There are multiple support frames 4; specifically, in this embodiment, there are ten support frames 4. In other embodiments, the number of rollers can be set according to actual usage. The upper straightening roller 5 and the lower straightening roller 6 are arranged in a one-to-one correspondence. The upper straightening roller 5 is mounted on an upper support frame, and the lower straightening roller 6 is mounted on a lower support frame. To improve the straightness of the titanium alloy tube, the angle between the upper straightening roller 5 and the lower straightening roller 6, as well as the distance between them, can be adjusted according to actual usage.

[0037] The titanium alloy straightening machine 100 also includes a frame 1 and a cleaning device. A support frame 4 is mounted on the frame 1, and part of the cleaning device is mounted on the support frame 4. The cleaning device is used to promptly remove particles from the surface of the titanium alloy tube, which is not shown. Specifically, in this embodiment, the diameter of the titanium alloy tube is 10 mm, and the material is titanium alloy. The cleaning device is mainly used to remove titanium shavings from the titanium alloy tube.

[0038] Furthermore, the cleaning device 200 includes an air supply mechanism, which includes a main air supply pipe 21 and branch air supply pipes 22. The main air supply pipe 21 is located below the frame 1. The output port of the main air supply pipe 21 is connected to the input port of the branch air supply pipe 22. The branch air supply pipe 22 has an air outlet 221 facing the titanium alloy pipe, which is connected to the input port. The air outlet 221 is located on the front or rear side of the straightening roller. The main air supply pipe 21 is a long pipe located below the frame 1. The main air supply pipe 21 has four output ports, which are correspondingly connected to four branch air supply pipes 22. In this embodiment, there are five sets of rollers. The air outlet 221 is set at the second set. This is because if a collision occurs during the forward movement of the titanium alloy pipe, it is generally between the rear end of the support frame of the first set of rollers and the front end of the support frame of the second set of rollers. Therefore, in this embodiment, the air outlet 221 is not set at the first set of rollers. The first set of rollers here refers to... Figure 1 The leftmost set of upper and lower straightening rollers, and so on, the second set of rollers refers to the set to the right of the first set of rollers. In this embodiment, the air outlet 221 is specifically located in front of the second set of rollers, the third set of rollers, the fourth set of rollers and the fifth set of rollers, and behind the first set of rollers.

[0039] The number of gas distribution pipes 22 can be one or more. Specifically, in this embodiment, the number of gas distribution pipes 22 is multiple. In other embodiments, the number of gas distribution pipes 22 may be only one. The gas distribution pipe 22 includes a first gas distribution pipe 222 and a second gas distribution pipe 223. One end of the first gas distribution pipe 222 is connected to the main gas distribution pipe 21, and the other end is connected to the second gas distribution pipe 223. The second gas distribution pipe 223 has an outlet 221 facing the titanium alloy pipe.

[0040] The cleaning device also includes a regulating mechanism for adjusting the gas flow rate. The regulating mechanism is located between the first gas distribution pipe 222 and the second gas distribution pipe 223, which are connected via the regulating mechanism. (Refer to...) Figure 2 As shown, the adjustment mechanism includes a pressure regulating valve 31, an adjustment seat 32, and a magnet 33. The pressure regulating valve 31 is mounted on the adjustment seat 32, and the magnet 33 is mounted on the support frame 4 of the straightening machine 100. The adjustment seat 32 is mounted on the magnet 33, that is, the magnet 33 is attracted to the support frame 4, and the adjustment valve 31 is attracted to the magnet 33. The installation of the adjustment mechanism is relatively simple, and the disassembly is relatively convenient, saving working time.

[0041] Furthermore, the second air distribution pipe 223 is movably mounted on the adjustment mechanism. The direction of the air outlet can be adjusted at any time by changing the position of the second air distribution pipe 223. More specifically, the second air distribution pipe 223 is made of copper, and its angle can be adjusted freely so that the air outlet faces the titanium alloy pipe precisely, making it convenient to use. The second air distribution pipe 223 has a hollow structure and a diameter of 6mm. The exhaust volume within the second air distribution pipe 223 can be adjusted at any time via the adjusting valve 31 to ensure that titanium shavings or other impurities on the titanium alloy pipe are removed from its surface. In addition, the cleaning device of this embodiment has a simple structure, is easy to use, and has a low manufacturing cost.

[0042] The titanium alloy tube straightening machine of this embodiment aims to solve the problem that when titanium alloy tubes collide with the support frame during the straightening process, metal debris falls off. If this debris is not cleaned up in time, it will form pits on the surface of the titanium alloy tube during subsequent straightening processes, reducing the straightening quality. In this embodiment, an air supply mechanism is set on the frame 1. The main air supply pipe 21 transmits gas to multiple first branch air supply pipes 222. The pressure regulating valve 31 between the first branch air supply pipes 222 and the second branch air supply pipes 223 can adjust the gas flow rate, similar to the principle of a faucet, to control the airflow. The air outlet 221 of the second branch air supply pipes 223 can directly blow away the debris on the titanium alloy tube, playing a timely cleaning role, avoiding the formation of pits, and ensuring the straightening quality of the titanium alloy tube.
