Description

Technical Field

[0001] This utility model relates to the field of pipe straightening technology, and in particular to a pretreatment device for straightening titanium alloy pipes. Background Technology

[0002] In the field of modern industrial manufacturing, titanium alloy tubes are widely used in many high-end industries such as aerospace, medical devices, and chemical equipment due to their high strength, low density, good corrosion resistance and high temperature resistance. However, during the production and manufacturing process of titanium alloy tubes, the tubes are prone to bending deformation due to the influence of rolling, transportation and other processes, which seriously affects their performance and subsequent processing accuracy.

[0003] Traditional equipment is difficult to adjust flexibly according to the different degrees of curvature of the pipe during use, resulting in some pipes not achieving the ideal straightening effect. At the same time, there is a lack of cleaning measures for the pipes before straightening, and insufficient attention is paid to the cleaning treatment of the pipe surface. The impurities remaining on the pipe surface not only affect the straightening quality, but also easily scratch the pipe surface during the straightening process, reducing product quality.

[0004] Based on this, a titanium alloy tube straightening pretreatment device is proposed for improvement. Utility Model Content

[0005] In view of the above-mentioned problems that existing methods are difficult to flexibly adjust according to different degrees of pipe curvature, and that the lack of cleaning measures for pipes before straightening affects the subsequent straightening effect and quality, this utility model is proposed.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a titanium alloy tube straightening pretreatment device, including a workbench, a straightening frame fixedly installed on one side of the top of the workbench, a plurality of first straightening wheels rotatably connected to the lower part of the inner wall of the straightening frame, the shafts of two adjacent first straightening wheels being connected by a first sprocket assembly, a plurality of through slots symmetrically opened in the middle of the straightening frame, a fixing frame fixedly connected to the top of the straightening frame, and the workbench including an adjustment mechanism for adjusting the spacing;

[0007] A servo motor is fixedly mounted on the top of the fixed frame via an L-shaped plate. The output shaft of the servo motor is fixedly sleeved with a first threaded post. A second threaded post is rotatably connected to the upper part of the first threaded post via a second sprocket assembly. The bottom ends of the first and second threaded posts pass through the fixed frame and are rotatably connected to the top of the straightening frame. The surfaces of the first and second threaded posts are threadedly connected to the same lifting plate. Several sets of mounting plates are fixedly connected to the bottom of the lifting plate. Several second straightening wheels are provided in the middle of the inner wall of the straightening frame. The shafts at both ends of the second straightening wheels pass through through slots and are rotatably connected to the inner wall of the mounting plates.

[0008] As a preferred embodiment, guide posts are fitted at all four corners of the lifting plate, and the bottom ends of the guide posts are fixedly connected to the top of the correction frame.

[0009] As a preferred embodiment, the corrective frame is provided with a fixing plate symmetrically at one end, and a slot is provided on the opposite side of the fixing plate. A cleaning frame is inserted into the inner wall of the slot, and a brush is fixedly connected to the inner wall of the cleaning frame.

[0010] As a preferred embodiment, the bottom end of the fixing plate is fixedly connected to a fixing seat, and the inner wall of the fixing seat is slidably connected to a dust collection drawer, which is located below the cleaning frame.

[0011] As a preferred embodiment, the worktable further includes a power mechanism for transmission, a mounting frame is fixedly connected to the bottom end of the worktable, a first motor is fixedly mounted on the top end of the mounting frame, and a speed reducer is fixedly mounted on the other side of the top end of the worktable.

[0012] As a preferred embodiment, the output end of the first motor is connected to the input end of the reducer via a belt assembly, and the output end of the reducer is connected to the shaft of one of the first straightening wheels in the middle of the straightening frame.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] 1. This utility model uses a servo motor to drive the first and second threaded columns, which, in conjunction with the second sprocket assembly, achieve synchronous rotation, thereby driving the lifting plate to move precisely up and down. It can accurately control the distance between the second straightening wheel and the first straightening wheel, thus precisely adjusting the extrusion force on the titanium alloy tube. This ensures that tubes with different degrees of curvature can be straightened efficiently and accurately, significantly improving straightening quality and efficiency. At the same time, it reduces the tediousness and errors of manual operation, reduces labor intensity, and improves production efficiency.

[0015] 2. This utility model features a fixed plate with slots, facilitating the quick installation and removal of the cleaning frame. When the pipe passes through the cleaning frame, the brush effectively removes dust, metal shavings, and other impurities adhering to the surface, preventing impurities from affecting the straightening effect and preventing the pipe surface from being scratched by impurities during the straightening process, thus ensuring the subsequent straightening effect and quality of the pipe. The impurities brushed off by the brush fall directly into the collection drawer below, eliminating the need for frequent manual cleaning and maintaining a clean working environment. At the same time, the collection drawer can be pulled out and emptied at any time, making operation simple and convenient and improving work efficiency. Attached Figure Description

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a titanium alloy tube straightening pretreatment device, including a workbench 1, a straightening frame 2 fixedly installed on one side of the top of the workbench 1, a plurality of first straightening wheels 31 rotatably connected to the lower part of the inner wall of the straightening frame 2, the shafts of two adjacent first straightening wheels 31 being connected by a first sprocket assembly 32, a plurality of through slots 22 symmetrically opened in the middle of the straightening frame 2, a fixing frame 21 fixedly connected to the top of the straightening frame 2, and the workbench 1 including an adjustment mechanism 4 for adjusting the spacing;

[0024] A servo motor 41 is fixedly mounted on the top of the fixed frame 21 via an L-shaped plate. The output shaft of the servo motor 41 is fixedly sleeved with a first threaded post 42. The upper part of the first threaded post 42 is rotatably connected to a second threaded post 44 via a second sprocket assembly 43. The bottom ends of the first threaded post 42 and the second threaded post 44 pass through the fixed frame 21 and are rotatably connected to the top of the straightening frame 2. The surfaces of the first threaded post 42 and the second threaded post 44 are threadedly connected to the same lifting plate 45. Several sets of mounting plates 46 are fixedly connected to the bottom of the lifting plate 45. Several second straightening wheels 47 are provided in the middle of the inner wall of the straightening frame 2. The shafts at both ends of the second straightening wheels 47 pass through the through groove 22 and are rotatably connected to the inner wall of the mounting plate 46.

[0025] Guide posts 48 are fitted at all four corners of the lifting plate 45, and the bottom of the guide posts 48 are fixedly connected to the top of the correction frame 2.

[0026] During use, the servo motor 41 is started, and its output shaft drives the first threaded column 42 to rotate. The upper part of the first threaded column 42 drives the second threaded column 44 to rotate through the second sprocket assembly 43, so that the two rotate in the same direction and synchronously.

[0027] While the first threaded column 42 and the second threaded column 44 rotate, they drive the lifting plate 45 to move up and down in the vertical direction. The guide columns 48 sleeved at the four corners of the lifting plate 45 can ensure that the lifting process is smooth and without deviation.

[0028] When the lifting plate 45 moves down, the lifting plate 45 drives the second straightening wheel 47 to move up and down in the middle of the straightening frame 2 through the mounting plate 46. The second straightening wheel 47 and the first straightening wheel 31 form an upper and lower clamping mechanism. By adjusting the height of the lifting plate 45, the squeezing force on the titanium alloy tube is controlled, and the straightening of the bent part is achieved.

[0029] This design uses a servo motor 41 to drive the first threaded post 42 and the second threaded post 44, which rotate synchronously with the second sprocket assembly 43. This drives the lifting plate 45 to move up and down precisely, allowing for precise control of the distance between the second straightening wheel 47 and the first straightening wheel 31. This enables precise adjustment of the extrusion pressure on the titanium alloy tube, ensuring that tubes with different degrees of curvature can be straightened efficiently and accurately. This significantly improves straightening quality and efficiency, while reducing the tediousness and errors of manual operation, lowering labor intensity, and increasing production efficiency.

[0030] Reference Figures 1-4 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: the correction frame 2 is symmetrically provided with a fixing plate 5 at one end, and a slot 51 is provided on the opposite side of the fixing plate 5. A cleaning frame 6 is inserted into the inner wall of the slot 51, and a brush 61 is fixedly connected to the inner wall of the cleaning frame 6.

[0031] A fixed base 7 is fixedly connected to the bottom of the fixed plate 5. A collection drawer 71 is slidably connected to the inner wall of the fixed base 7. The collection drawer 71 is located below the cleaning frame 6.

[0032] During use, the fixing plate 5 has a slot 51, which facilitates the quick installation and removal of the cleaning frame 6. When the pipe passes through the cleaning frame 6, the brush 61 can effectively remove dust, metal shavings and other impurities attached to the surface, avoid impurities affecting the straightening effect, prevent the pipe surface from being scratched by impurities during the straightening process, and ensure the quality of the pipe surface.

[0033] Impurities brushed off by the brush 61 fall directly into the collection drawer 71 below, eliminating the need for frequent manual cleaning and keeping the working environment clean. At the same time, the collection drawer 71 can be pulled out and emptied at any time, making operation simple and convenient and improving work efficiency.

[0034] Reference Figures 1-4This is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that the workbench 1 also includes a power mechanism 3 for transmission. A mounting frame 33 is fixedly connected to the bottom end of the workbench 1. A first motor 34 is fixedly installed on the top end of the mounting frame 33. A reducer 36 is fixedly installed on the other side of the top end of the workbench 1.

[0035] The output end of the first motor 34 is connected to the input end of the reducer 36 via a belt assembly 35. The output end of the reducer 36 is connected to the shaft of one of the first straightening wheels 31 in the middle of the straightening frame 2.

[0036] During operation, after the first motor 34 starts, the belt assembly 35 transmits the power of the first motor 34 to the reducer 36. The reducer 36 reduces the input high-speed power and increases the torque to meet the working requirements. The output shaft of the reducer 36 drives the shaft of a first straightening wheel 31 in the middle of the straightening frame 2. This wheel drives the adjacent first straightening wheel 31 to rotate synchronously through the first sprocket assembly 32, forming a continuous transmission chain, thereby effectively driving the titanium alloy tube to move. At the same time, in conjunction with the downward pressing action of the second straightening wheel 47, continuous operation of straightening while driving is achieved, improving production efficiency.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
