Description

Technical Field

[0001] This utility model relates to the field of exhaust connection pipe manufacturing technology, specifically a pressure-pull device for exhaust connection pipe manufacturing. Background Technology

[0002] As a key component of many devices, exhaust connection pipes have a wide range of applications and play an indispensable role in industries such as automobiles, aerospace, and industrial equipment.

[0003] Taking the automotive industry as an example, the exhaust pipe is an important component of the vehicle's exhaust system, and its performance directly affects the vehicle's emissions, power performance, and ride comfort. With increasingly stringent environmental regulations and rising consumer demands for vehicle performance, automakers are setting higher standards for the quality and performance of exhaust pipes.

[0004] In the production process of exhaust pipes, the compression and tensioning device plays a core role. Traditional compression and tensioning devices used in the production of exhaust pipes have relatively simple functions, only capable of simple compression or stretching operations. When in use, the pipe will bend and deform when impacted by external forces. Utility Model Content

[0005] The purpose of this invention is to provide a pressure-pull device for the production of exhaust connecting pipes, so as to solve the problem mentioned in the background art that the connecting pipe will bend and deform when it is hit by external forces during use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pressure-pull device for producing exhaust connection pipes, comprising a frame and support legs, wherein the support legs are fixedly connected to the bottom of the frame, and a support device is provided above the frame;

[0007] The support device includes a mounting cylinder, an adjusting motor, a mounting cover, a connecting rod, a connecting plate, and a support plate. The mounting cylinder is fixedly installed above the frame, and the adjusting motor is fixedly installed inside the mounting cylinder at the bottom. The outer surface of the mounting cylinder has four through holes. The mounting cover is fixedly connected to the inside of the mounting cylinder, and the connecting rod is slidably connected to the inside of the mounting cover. The connecting plate is fixedly connected to the end of the connecting rod away from the mounting cover, and the support plate is installed on the side of the connecting plate away from the mounting cylinder. The shape of the connecting plate matches the through holes. By adjusting the motor to drive the variable diameter structure to move, the connecting plate and the support plate move closer or further apart to adapt to the internal dimensions of the exhaust connecting pipe, thereby supporting the inside of the connecting pipe and preventing the connecting pipe from bending and deforming due to external impacts.

[0008] Preferably, the connecting plate has through holes on both the upper and lower sides of its outer surface, and a guide post is slidably connected inside the through hole. A spring is sleeved on the outer surface of the guide post between the connecting plate and the support plate. The guide post is fixedly connected to one side of the support plate. The spring prevents the support plate from excessively squeezing the inner wall of the connecting pipe due to excessive adjustment of the variable diameter structure, thus damaging it.

[0009] Preferably, a guide plate is installed inside the mounting cover, a shaft is fixedly connected above the connecting rod, a slider is fixedly connected above the shaft, the shaft is slidably connected to the guide rail inside the guide plate, a variable diameter plate is fixedly installed above the mounting cover, the slider is slidably connected inside the groove of the variable diameter plate, and the guide plate is connected to the output end of the adjusting motor. By adjusting the motor, the guide plate is driven to rotate, causing the slider to move along the variable diameter plate, making them move closer or further apart, and finally causing the connecting rod and the support plate to move to achieve the purpose of changing the diameter.

[0010] Preferably, a slide rail is provided on the left side of the frame, a cylinder is installed on the top of the frame, a lifting plate is connected to the output end of the cylinder, the lifting plate is internally connected to the slide rail and slidably connected to the frame through the slide rail, a positioning column is fixedly connected on the top of the lifting plate, the positioning column passes through the top of the frame, and the lifting plate is driven by the cylinder to rise and fall along the slide rail, so that the clamping structure rises and falls to compress and stretch the connecting pipe.

[0011] Preferably, a threaded hole is provided on the top of the frame, and the frame and the cylinder are connected by bolts through the threaded hole, which facilitates maintenance and replacement of the cylinder and improves the convenience of the device.

[0012] Preferably, the lifting plate is fixedly connected to the lower part of the frame with an installation plate. A lead screw motor is fixedly installed on the front of the installation plate. A bidirectional lead screw is connected to the output end of the lead screw motor. A clamping plate is threaded to the outer surface of the bidirectional lead screw. The lead screw motor drives the bidirectional lead screw to rotate, which ultimately drives the clamping plates to move closer together to clamp and fix the two ends of the connecting pipe.

[0013] Preferably, the clamping surface of the clamping plate is provided with an anti-slip coating, which is an epoxy resin anti-slip coating, to prevent the two ends of the connecting pipe from detaching from the clamping plate and to improve the compression and tension effect.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The pressure-pull device for producing the exhaust connecting pipe uses a motor to drive the variable diameter structure to move the connecting plate and the support plate closer or further apart to adapt to the internal dimensions of the exhaust connecting pipe. This supports the inside of the connecting pipe and prevents it from bending or deforming due to external impacts. A spring prevents the support plate from excessively pressing against the inner wall of the connecting pipe and causing damage due to over-adjustment of the variable diameter structure. By adjusting the motor to drive the guide disc to rotate, the slider moves along the variable diameter disc to move closer or further apart, ultimately moving the connecting rod and the support plate to achieve the purpose of changing the diameter.

[0016] 2. The pressure-pull device for producing the exhaust connecting pipe uses a cylinder to drive the lifting plate to rise and fall along the slide rail, which in turn causes the clamping structure to rise and fall to compress and stretch the connecting pipe. The screw motor drives the bidirectional screw to rotate, which in turn causes the clamping plates to move closer together to clamp and fix the two ends of the connecting pipe. The anti-slip coating can prevent the two ends of the connecting pipe from detaching from the clamping plates, thus improving the pressure-pull effect. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Addressing the current issue of connecting pipes bending and deforming upon external impact during use, this example provides a pressure-pull device for producing exhaust connecting pipes. Please refer to [link to example]. Figures 1-4 The embodiment provides a pressure-pull device for producing exhaust connecting pipes, which can support the inner wall of the exhaust connecting pipe to prevent bending and deformation caused by external impacts. It can also adjust the position of the support plate according to the internal dimensions of the connecting pipe to better provide support. This pressure-pull device for producing exhaust connecting pipes includes a frame 1 and support legs 101. The support legs 101 are fixedly connected to the bottom of the frame 1, and a support device is provided on the top of the frame 1.

[0024] The support device includes a mounting cylinder 2, an adjusting motor 201, a mounting cover 202, a connecting rod 203, a connecting plate 204, and a support plate 205.

Four through holes are opened on the outer surface of the mounting cylinder 2. The mounting cover 202 is fixedly connected to the inside of the mounting cylinder 2. The connecting rod 203 is slidably connected to the inside of the mounting cover 202. The connecting plate 204 is fixedly connected to the end of the connecting rod 203 away from the mounting cover 202. The support plate 205 is installed on the side of the connecting plate 204 away from the mounting cylinder 2. The shape of the connecting plate 204 matches the through holes. Through holes are provided on the upper and lower sides of the surface. A guide post 206 is slidably connected inside the through hole. A spring 207 is sleeved on the outer surface of the guide post 206 between the connecting plate 204 and the support plate 205. The guide post 206 is fixedly connected to one side of the support plate 205. A guide plate 209 is installed inside the mounting cover 202. A shaft is fixedly connected above the connecting rod 203. A slider 208 is fixedly connected above the shaft. The shaft is slidably connected to the guide rail inside the guide plate 209. A variable diameter plate 210 is fixedly installed above the mounting cover 202. The slider 208 is slidably connected inside the groove of the variable diameter plate 210. The guide plate 209 is connected to the output end of the adjusting motor 201.

[0025] In this embodiment, by adjusting the motor 201 to drive the variable diameter structure to move the connecting plate 204 and the support plate 205 closer or further apart to adapt to the internal size of the exhaust connecting pipe, the internal structure of the connecting pipe is supported to prevent bending and deformation caused by external collisions. The spring 207 prevents the support plate 205 from being over-pressed on the inner wall of the connecting pipe due to excessive adjustment of the variable diameter structure, which would damage it. By adjusting the motor 201 to drive the guide plate 209 to rotate, the slider 208 moves along the variable diameter plate 210 to move closer or further apart, and finally the connecting rod 203 and the support plate 205 move to achieve the purpose of changing the diameter.

[0026] Example 2: Based on Example 1, please refer to... Figures 1-4It can clamp and fix both ends of the connecting pipe. The anti-slip coating can prevent the two ends of the connecting pipe from detaching from the clamping plate and improve the compression and tension effect. A slide rail 402 is provided on the left side of the frame 1. A cylinder 4 is installed on the top of the frame 1. The output end of the cylinder 4 is connected to a lifting plate 401. The lifting plate 401 is internally connected to the slide rail 402 and slidably connected to the frame 1 through the slide rail 402. A positioning column 403 is fixedly connected on the top of the lifting plate 401. The positioning column 403 passes through the top of the frame 1. A threaded hole is provided on the top of the frame 1. The frame 1 and the cylinder 4 are connected by bolts through the threaded hole. A mounting plate 301 is fixedly connected to the bottom of the lifting plate 401 and the frame 1. A lead screw motor 3 is fixedly installed on the front of the mounting plate 301. A bidirectional lead screw 302 is connected to the output end of the lead screw motor 3. A clamping plate 303 is threadedly connected to the outer surface of the bidirectional lead screw 302. The clamping surface of the clamping plate 303 is provided with an anti-slip coating. The anti-slip coating is an epoxy resin anti-slip coating.

[0027] In this embodiment, the cylinder 4 drives the lifting plate 401 to rise and fall along the slide rail 402, which ultimately causes the clamping structure to rise and fall to compress and stretch the connecting pipe. The lead screw motor 3 drives the bidirectional lead screw 302 to rotate, which ultimately causes the clamping plates 303 to move closer to each other to clamp and fix the two ends of the connecting pipe. The anti-slip coating can prevent the two ends of the connecting pipe from detaching from the clamping plates 303 and improve the compression and tension effect.

[0028] Working principle: By adjusting the motor 201 to drive the variable diameter structure, the connecting plate 204 and the support plate 205 move closer or further apart to adapt to the internal dimensions of the exhaust connecting pipe, thereby supporting the inside of the connecting pipe and preventing bending and deformation caused by external impacts. A spring 207 prevents excessive adjustment of the variable diameter structure from causing excessive pressure on the inner wall of the connecting pipe by the support plate 205, which could damage it. The motor 201 drives the guide plate 209 to rotate, causing the slider 208 to move along the variable diameter plate 210, moving closer or further apart, ultimately moving the connecting rod 203 and the support plate 205 to achieve the variable diameter. The cylinder 4 drives the lifting plate 401 to rise and fall along the slide rail 402, ultimately causing the clamping structure to rise and fall, compressing and stretching the connecting pipe. The screw motor 3 drives the bidirectional screw 302 to rotate, ultimately causing the clamping plates 303 to move closer together, clamping and fixing both ends of the connecting pipe. The anti-slip coating prevents the ends of the connecting pipe from detaching from the clamping plates 303, improving the compression and tension effect. Cylinder 4 adopts the DNC series, regulating motor 201 adopts the MD series, and lead screw motor 3 adopts the ASDA-B3 series.
