Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically a bending device for automotive parts processing. Background Technology

[0002] Automotive parts processing encompasses the various units and products that constitute the overall automotive parts processing industry. Automotive parts are diverse, and with the improvement of people's living standards, car consumption is increasing, leading to a growing market for automotive parts. In recent years, automotive parts manufacturing plants have also developed rapidly. During the production of automotive parts, it is often necessary to process and bend tubing. For example, an existing patent for a bending device for automotive parts processing (patent number CN201921871377.9) achieves tubing bending, but in practical applications, the limiting arc plate of this patent cannot effectively fix the tubing. During bending, the left end of the tubing is easily not fixed, resulting in an unsatisfactory bending effect. Furthermore, the side of the arc-shaped pressure plate in this patent is a sharp object, which can easily damage the tubing, making it impractical. Therefore, we propose a bending device for automotive parts processing. Utility Model Content

[0025] The device body 1 includes a chassis 101, support plates 102, a first lead screw 103, a handle 104, a slide bar 105, and a scale bar 106. Two sets of support plates 102 are welded to the left side of the top surface of the chassis 101. The bottom of the rear support plate 102 is rotatably connected to the first lead screw 103 for driving the slide plate 201 to move via a bearing.

One side of the 3 is welded with a sliding rod 105, and the top surface of the chassis 101 is provided with a scale bar 106. Rotating the handle 104 in both directions drives the first lead screw 103 to rotate, causing the slide plate 201 to move left and right to adjust the bending position.

This device, together with the fixing device 2 and the bending device 3, realizes the fixing and bending position adjustment when bending automobile pipes. Furthermore, the cylindrical limiting post 303 is used to avoid damage to the bent part of the pipe, thereby improving the bending effect and stability.

[0026] Furthermore, the fixing device 2 includes a sliding plate 201, a sliding groove 202, a clamping plate 203, a second lead screw 204, and a throttle 205. The sliding plate 201 is slidably connected to the outer ring of the two sets of sliding rods 105. The rear bottom of the sliding plate 201 is threadedly connected to the outer ring of the first lead screw 103. The inner cavity of the sliding plate 201 is provided with a sliding groove 202 for limiting the range of motion of the clamping plate 203. The clamping plate 203 for clamping the pipe is slidably connected in the sliding groove 202. The top of the clamping plate 203 is rotatably connected to the second lead screw 204 through a bearing. The middle section of the second lead screw 204 is threadedly connected to the middle of the top surface of the sliding plate 201. The top end of the second lead screw 204 passes through the sliding plate 201 and is fixedly inserted with the throttle 205. The automobile pipe is passed through the bracket 301 and inserted into the sliding plate 201. Rotating the throttle 205 in the forward direction drives the second lead screw 204 to rotate, causing the clamping plate 203 to descend and clamp the pipe.

[0027] Furthermore, the bending device 3 includes a bracket 301, a first hydraulic rod 302, a limiting post 303, a push plate 304, and a second hydraulic rod 305. The bracket 301 is welded to the middle of the top surface of the chassis 101. The first hydraulic rod 302 is fixedly installed on the top of the inner cavity of the bracket 301. The output end of the first hydraulic rod 302 is fixedly connected to the limiting post 303. The bottom of the inner cavity of the bracket 301 is rotatably connected to the push plate 304 for bending the pipe through a rotating shaft. The front and rear ends of the right side of the push plate 304 are both connected to rotating shafts, and the rotating shafts are fixedly connected to the second hydraulic rod 305 for driving the push plate 304 to rotate. The bottom end of the second hydraulic rod 305 is hinged to the right side of the top surface of the chassis 101 through a rotating shaft. The first hydraulic rod 302 pushes the limiting post 303 down to fit the pipe, and then the second hydraulic rod 305 pushes the push plate 304 and the pipe to rotate and bend them.

[0028] Furthermore, two sets of slide bars 105 are provided, distributed between the support plate 102 and the bracket 301, and the slide bars 105 are used to limit the range of motion of the slide plate 201.

[0029] Furthermore, the bottom surface of the clamping plate 203 is provided with a rubber anti-slip layer, and the front and rear sides of the clamping plate 203 are provided with protrusions. The protrusions are slidably connected in the slide groove 202 to improve the stability of the clamping plate 203 in clamping the pipe, and the slide groove 202 is used to limit the range of motion of the clamping plate 203.

[0030] Furthermore, the limiting post 303 is a cylindrical solid metal tube, and an arc-shaped groove is provided at the bottom of the limiting post 303 to prevent damage to the bent parts of the tube.

[0031] Furthermore, the second hydraulic rod 305 is provided in two sets, distributed on the front and rear sides of the push plate 304, to improve bending efficiency.

[0032] Working principle: When in use, the automotive pipe is passed through the bracket 301 and inserted into the slide plate 201. Rotating the handle 205 in the forward direction drives the second lead screw 204 to rotate, causing the clamping plate 203 to descend and clamp the pipe. Then, rotating the handle 104 in both directions drives the first lead screw 103 to rotate, causing the slide plate 201 to move left and right to adjust the bending position. The length of the bending position is checked according to the scale bar 106. Then, the first hydraulic rod 302 pushes the limiting post 303 to descend and fit against the pipe. Then, the second hydraulic rod 305 pushes the push plate 304 and the pipe to rotate and bend it. This achieves the fixation of the automotive pipe during bending and the adjustment of the bending position. The cylindrical limiting post 303 avoids damage to the bent part of the pipe, improving the bending effect and stability.
