Technical Field

[0001] This utility model relates to the field of pipe fitting processing equipment, specifically to an automatic straightening machine for multi-length crossbar pipe fittings. Background Technology

[0002] The processing of metal tubing mainly involves stamping and other processing methods. Crossbars are a type of tubing shaped like the Chinese character "I". Crossbars are one of the components of the vehicle frame. During the processing, drilling and punching are required. During the processing, punching and cutting processes will apply local high stress to the metal tubing, causing the tubing to bend and deform. Therefore, the tubing needs to be corrected and shaped.

[0003] An existing pipe straightening device, disclosed in CN209716117U, includes a worktable and three sets of adjusting frames arranged side by side on the worktable. Each set of adjusting frames is provided with a lower shaft, an upper shaft, a threaded adjusting rod, and a slider. Each lower shaft is provided with a lower straightening roller, and each upper shaft is provided with an upper straightening roller. The lower and upper straightening rollers on the same adjusting frame are aligned vertically. The two ends of the lower shaft are fixedly connected to the adjusting frame, and the two ends of the upper shaft are fixedly connected to the slider. The slider is located in the cavity in the upper part of the adjusting frame. The threaded adjusting rod passes through a threaded hole located at the top of the adjusting frame, and the bottom of the threaded adjusting rod is fixedly connected to the slider.

[0004] Existing straightening devices can only be used to straighten a single round tube, and cannot be used to straighten an I-shaped tube composed of multiple tubes. Furthermore, the overall length of an I-shaped tube varies, so an automatic straightening machine for multi-length crossbar tubes is needed. Utility Model Content

The first shaping and translation device and the second shaping and translation device are arranged opposite to each other on the frame. The second positioning and straightening component includes a second positioning seat, a third shaping and translation device, and a second shaping block. The sidewall of the first shaping block facing the first positioning seat and the sidewall of the second shaping block facing the second positioning seat are both provided with U-shaped grooves.

[0007] Furthermore, the adjustment and translation mechanism is specifically a lead screw adjustment module, and the slide table is slidably connected to the frame.

[0008] Furthermore, both the first shaping and translation device and the second shaping and translation device are fixedly connected to the frame, the first positioning seat is fixedly connected to the moving end of the first shaping and translation device, and the first shaping block is fixedly connected to the moving end of the second shaping and translation device; both the second positioning seat and the third shaping and translation device are fixedly connected to the slide table, and the moving end of the third shaping and translation device passes through the second positioning seat and is fixedly connected to the second shaping block.

[0009] Furthermore, the first shaping and translation device, the second shaping and translation device, and the third shaping and translation device are all cylinders, the first positioning seat and the first shaping block are slidably connected to the frame, and the second positioning seat is slidably connected to the slide table.

[0010] Furthermore, both the first and second positioning seats have positioning grooves, which are T-shaped.

[0011] Furthermore, there are at least two first shaping blocks, and the first shaping blocks are distributed on both sides of the first positioning seat; there are at least two second shaping blocks, and the two second shaping blocks are distributed on both sides of the second positioning seat.

[0012] The beneficial effects of this utility model are: the adjustable translation mechanism can drive the second positioning and correction component to move laterally, thereby realizing the positioning and clamping of cross rod tubes of different lengths;

[0013] The U-shaped groove structure works in conjunction with the double-shaping translation device, combined with the T-shaped positioning groove, to automatically straighten and correct the ends of the cross-rod fittings, resulting in high efficiency and good correction effect.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0019] Example:

[0020] refer to Figures 1-2 An automatic straightening machine for multi-length crossbar pipe fittings is shown, including a frame 1. A first positioning and straightening component and an adjustment and translation mechanism 2 are respectively arranged on both sides of the frame 1. A slide table 3 is fixedly connected to the moving platform of the adjustment and translation mechanism 2. A second positioning and straightening component is arranged on the slide table 3. The first positioning and straightening component includes a first shaping and translation device 401, a first positioning seat 402, a second shaping and translation device 403, and a first shaping block 404. The first shaping and translation device 401 and the second shaping and translation device 403 are arranged opposite to each other on the frame 1. The second positioning and straightening component includes a second positioning seat 501, a third shaping and translation device 502, and a second shaping block 503. The side wall of the first shaping block 404 facing the first positioning seat 402 and the side wall of the second shaping block 503 facing the second positioning seat 501 are both provided with U-shaped grooves 6.

[0021] The adjustment and translation mechanism 2 is specifically a lead screw adjustment module. According to actual needs, the lead screw can be rotated by hand-cranking or motor-driven to realize the translation of the moving platform of the lead screw adjustment module. The frame 1 can guide the sliding of the slide table 3.

[0022] The first shaping and translation device 401 is used to drive the first positioning seat 402 to translate; the second shaping and translation device 403 is used to drive the first shaping block 404 to translate; and the third shaping and translation device 502 is used to drive the second shaping block 503 to translate. The first shaping and translation device 401, the second shaping and translation device 403, and the third shaping and translation device 502 are all cylinders. Using cylinders results in relatively low production costs and low maintenance costs. The frame 1 can guide the sliding of the first positioning seat 402 and the first shaping block 404, and the slide table 3 can guide the sliding of the second positioning seat 501.

[0023] Both the first positioning seat 402 and the second positioning seat 501 have positioning grooves, which are T-shaped and used to position the crossbar. The T-shaped grooves can accommodate the positioning of adjacent pipe connections. There are at least two first shaping blocks 404, which are distributed on both sides of the first positioning seat 402; there are at least two second shaping blocks 503, which are distributed on both sides of the second positioning seat 501, to improve the shaping effect of the crossbar.

[0024] The working principle of this utility model is as follows: First, based on the length of the crossbar, the distance between the first positioning seat 402 and the second positioning seat 501 is adjusted by driving the slide table 3 through the adjusting translation mechanism 2. During the correction, the crossbar is placed along the first positioning seat 402 and the second positioning seat 501. Then, the first shaping translation device 401 drives the first positioning seat 402 to slide towards the first shaping block 404, and the second shaping translation device 403 drives the first shaping block 404 to slide towards the first positioning seat 402, so that the first positioning seat 402 and the first shaping block 404 move towards each other. Below, the end of the crossbar is shaped after contacting the U-shaped groove; after the shaping of one end is completed, the moving ends of the first shaping translation device 401 and the second shaping translation device 403 are reset (after the crossbar is positioned in the T-shaped groove, the crossbar is allowed to move along the travel direction of the first shaping translation device 401 or the third shaping translation device during the shaping process), the third shaping translation device 502 drives the second positioning seat 501 to slide towards the second shaping block 53 to perform shaping and correction processing on the other end, and the third shaping translation device 502 is reset after the processing is completed.

[0025] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
