Abstract
Description
Technical Field
[0001] This utility model relates to the field of bending device technology, specifically a backup bending device for muffler steel tubes. Background Technology
[0002] A silencer is a device that blocks sound transmission while allowing airflow. It is installed in the airflow channel of aerodynamic equipment (such as blowers and air compressors) or in the intake and exhaust systems. Currently, during the manufacturing process of silencer steel pipes, bending devices are required to bend the silencer steel pipes to meet different needs.
[0003] According to patent publication number CN 222020455 U, a bending device for producing round tubes for automobile exhaust pipe brackets is disclosed. This device uses an L-shaped plate and a bending disc to clamp and fix the round tube body during bending, reducing movement during the bending process. By adjusting the position of the bending disc and the distance between the two push plates, the round tube body can be bent to different radii to meet different bending requirements. However, the device requires manual operation to fix the steel pipe, which affects work efficiency.
[0004] To address this issue, we propose a backup bending device for muffler steel tubing. Utility Model Content

[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings. Example 1:
[0025] like Figure 1-4As shown, this utility model provides a technical solution: a spare bending device for muffler steel tubes, including a workbench 1, a mounting bracket 2 fixedly installed at the bottom of the workbench 1, a through hole 4 opened on the upper part of the workbench 1, and a connecting component 3 disposed on one side of the workbench 1. The connecting component 3 includes a fixing mechanism 31 disposed on the upper part of the workbench 1, and an adjustment mechanism 32 is also disposed on the upper part of the workbench 1. The fixing mechanism 31 includes a first electric telescopic rod 311 fixedly installed on the upper part of the workbench 1, and a fixing plate 31 is fixedly connected to the output end of the first electric telescopic rod 311. 2. A convex groove 313 is provided on the inner side of the fixing plate 312. A convex column 314 is slidably connected to the inner wall of the convex groove 313. A connecting plate 315 is fixedly connected to the outer side of the convex column 314. An anti-slip plate 316 is fixedly connected to the outer side of the connecting plate 315. A rotating rod 317 is rotatably connected to one side of the fixing plate 312 through a bearing. A locking rod 318 is movably connected to one end of the rotating rod 317. A limit block 319 is fixedly connected to the outer end of the locking rod 318. A first spring 3110 is fixedly connected to the inner side of the limit block 319. A locking groove 3111 is provided on the outer side of the fixing plate 312.
[0026] In this embodiment, the snap-fit rod 318 is snapped into the snap-fit groove 3111, and the inner end of the first spring 3110 is fixedly connected to the rotating rod 317. Through the cooperation of the first electric telescopic rod 311 and the fixing plate 312, the steel pipe can be pressed and fixed. At the same time, by setting the anti-slip plate 316, the steel pipe is less likely to slip after being fixed, thus making the workpiece more stable during bending. In addition, through the cooperation of the convex groove 313, convex column 314, connecting plate 315, anti-slip plate 316, rotating rod 317, snap-fit rod 318, limiting block 319, first spring 3110, and snap-fit groove 3111, it is convenient for manual replacement of the anti-slip plate 316 with large wear in a timely manner, thereby achieving a better fixing effect on the muffler steel pipe.
[0027] Furthermore, the inner side of the rotating rod 317 is fitted to the outer side of the convex column 314.
[0028] In use, the muffler steel pipe is manually placed between the small bending disc 329 and the fixing plate 312. Then, the first electric telescopic rod 311 moves the fixing plate 312 towards the small bending disc 329, thus fixing the steel pipe to the outer wall of the small bending disc 329. Simultaneously, the anti-slip plate 316 prevents the workpiece from slipping after fixing, facilitating subsequent bending operations. Furthermore, when the anti-slip plate 316 needs to be disassembled, the locking rod 318 is manually pulled outward to separate it from the locking groove 3111. Then, the rotating rod 317 is manually rotated away from the outer side of the convex column 314. Under the action of the convex groove 313 and the convex column 314, the connecting plate 315 can be manually removed, facilitating the replacement of the worn anti-slip plate 316. This provides a better anti-slip effect for the muffler steel pipe, preventing it from slipping during bending. Example 2:
[0029] Based on Embodiment 1, a preferred embodiment of the muffler steel tube standby bending device provided by this utility model is, for example... Figures 1 to 4 As shown: The adjustment mechanism 32 includes a second electric telescopic rod 321 fixedly installed on the upper part of the workbench 1. The output end of the second electric telescopic rod 321 is fixedly connected to a mounting base 322. A motor 323 is fixedly installed on one side of the mounting base 322 via a base. A bidirectional threaded rod 324 is fixedly connected to the output end of the motor 323. A push rod 325 is slidably connected to the inner wall of the mounting base 322. A hydraulic cylinder 326 is fixedly installed on the upper part of the mounting frame 2. A large bending disc 327 is fixedly connected to the output end of the hydraulic cylinder 326. A mounting column 3212 is fixedly installed on the upper part of the large bending disc 327. A small bending disc 329 is fixedly installed at the top of the mounting column 3212. A medium bending disc 328 is fixedly connected to the outer wall of the mounting column 3212. A limit post 3210 is fixedly installed on the upper part of the mounting frame 2. A stop block 3211 is fixedly connected to the top of the limit post 3210.
[0030] In this embodiment, the push rod 325 is threaded to the outer wall of the bidirectional threaded rod 324. The bidirectional threaded rod 324 is rotatably connected to the mounting base 322 through a bearing. Through the cooperation of the second electric telescopic rod 321, the mounting base 322, the motor 323, the bidirectional threaded rod 324, the push rod 325, the hydraulic cylinder 326, the large bending disc 327, the medium bending disc 328, and the small bending disc 329, the muffler steel pipe can be bent into finished products of different radii, thereby meeting different bending requirements and increasing the applicability of the device.
[0031] Furthermore, the large bending disc 327, the medium bending disc 328, and the small bending disc 329 are all slidably connected to the outer wall of the limiting post 3210.
[0032] After the muffler steel pipe is fixed, the second electric telescopic rod 321 drives the mounting base 322 to move towards the small bending disc 329, thereby allowing the mounting base 322, which is fixedly connected to the output end of the second electric telescopic rod 321, to move synchronously. This, in turn, allows the push rod 325 to move synchronously, enabling the fixed steel pipe to be bent under pressure. The motor 323 drives the bidirectional threaded rod 324 to rotate, allowing the push rod 325, which is threaded onto the outer wall of the bidirectional threaded rod 324, to move within the mounting base 322. Simultaneously, the hydraulic cylinder 326 drives the large bending disc 327 to move upward, thereby adjusting the height of the large bending disc 327 and the medium bending disc 328. This allows the muffler steel pipe to be bent into finished products of different radii, meeting various bending requirements and increasing the applicability of the device. At the same time, the limit post 3210 and the stop block 3211 prevent excessive pressure from the first electric telescopic rod 311 from damaging the hydraulic cylinder 326.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
