[0002] At present, cars have become the main means of transportation for people. Cars are made up of thousands of parts. The quality of the parts also determines the overall quality of the car. There are many rods on the car, and the rods are not necessarily straight. Some rods have a certain bending angle. During the automobile processing process, the rods need to be bent according to the needs of use.

A support bar is arranged at the end of the connecting rod, and a pointer is arranged on the surface of the support bar. The right side surface of the fixed seat is contacted and connected with a rod, and the rod is placed on the upper surface of the base plate. A first cylinder is fixedly connected to the upper end of the base plate, and a second cylinder is fixedly connected to the upper end of the base plate.

In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. When the existing pipe bending machine needs to bend the pipe fitting in multiple places, the bending assembly is driven by a driving motor to move. Although the moving position of the bending assembly can realize bending of the pipe fitting in different places, the required workbench is also increased to meet the demand for multiple bending of long pipe fittings as much as possible, which increases the manufacturing cost of the pipe bending machine; 2. The hydraulic push rod of the existing pipe bending machine is set on the right side, and the pipe fitting can only be bent to the left. The bending direction is single and the adaptability is poor.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 4The utility model provides a technical solution: an easily adjustable automobile parts processing pipe bending machine, comprising a workbench 1, two fixed plates 2 are fixedly connected to the top two sides of the workbench 1, a conveying component 3 is arranged between the two fixed plates 2, and a bending component 4 is arranged on the top left side of the workbench 1.

[0020] In this embodiment, Figure 1 and Figure 3 As shown, the conveying assembly 3 includes a threaded rod 301 rotatably connected to the middle part of the fixed plate 2, the middle part of the threaded rod 301 is threadedly connected to two moving boxes 302, the bottom of the two moving boxes 302 are fixedly connected with a T-shaped slider 303, the T-shaped slider 303 is slidably connected to the middle part of the T-shaped slide groove 304, and the interior of the two moving boxes 302 is provided with a rotating shaft 305, the top of the rotating shaft 305 is fixedly connected with a conveying wheel 306, the outer side of the conveying wheel 306 is provided with an anti-slip ring 3011, the rotating shaft 305 passes through the middle part of the secondary pulley 307, the outer side of the secondary pulley 307 is movably connected with a synchronous belt 308, one side of the synchronous belt 308 is movably connected with a main pulley 309, and the middle part of the main pulley 309 is fixedly connected to the output end of the first motor 3010.

[0021] In this embodiment, Figure 1 and Figure 3 As shown, the two moving boxes 302 are symmetrically distributed about the center line of the workbench 1, and the two moving boxes 302 are divided into a main box and a sub-box, wherein the first motor 3010 is used as a driving source inside the main box, and two rotating shafts 305 are rotatably connected to the bottom of the box in the sub-box; when the pipe is stuck in the middle by the anti-skid rings 3011 on both sides for transportation, the anti-skid ring 3011 on the top of the rotating shaft 305 is driven to rotate by the first motor 3010, the main pulley 309, the synchronous belt 308 and the sub-pulley 307, The auxiliary boxes in the two moving boxes 302 are not equipped with motors. They rotate through the friction between the anti-slip ring 3011 and the pipe fittings, which plays a role in assisting the transportation of the pipe fittings. Only one motor is used to save costs. In addition, this structure transports the pipe fittings toward the bending mechanism to bend different positions on the pipe fittings. Compared with the structure that uses a mobile bending mechanism to bend different positions of the pipe fittings, this structure does not need to reserve a large amount of travel for the bending mechanism. Therefore, the bending machine is smaller in size and has a low manufacturing cost.

[0022] In this embodiment, Figure 1 As shown, one end of the threaded rod 301 passes through the fixed plate 2 and is connected to the rocker, and the threads on the threaded rod 301 are in two opposite directions, and the threads in the two opposite directions are symmetrically distributed about the center line of the workbench 1; this structure can drive the threaded rod 301 to rotate through the rocker, and when the threaded rod 301 rotates, it drives the two moving boxes 302 to move in opposite directions, thereby driving the conveying wheel 306 on the top to clamp the pipe fittings, so as to facilitate the fixed conveying of pipe fittings of different sizes.

[0023] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the bending assembly 4 includes a second motor 401 fixedly connected to the bottom of the workbench 1, the output end of the second motor 401 passes through the workbench 1 and is connected to the middle of the bottom surface of the main gear 402, a sub-gear 403 is meshed on one side of the main gear 402, a support shaft 404 is fixedly connected to the bottom of the sub-gear 403, a hole 405 is opened in the middle of the sub-gear 403, a limit block 406 is provided on the inner wall of the hole 405, and the limit block 406 is slidably connected to the limit groove In the middle of 407, the limit groove 407 is opened on one side of the bending column 408, and a rack 409 is provided on the side of the bending column 408 away from the limit groove 407. The bottom of the rack 409 is meshed with one side of the adjusting gear 4010, and the middle of the rear side of the adjusting gear 4010 is fixedly connected to the output end of the third motor 4011. The top of the third motor 4011 is fixedly connected with a connecting block 4012, and a reserved hole 4013 is opened at the bottom of the bending column 408.

[0024] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the top of the connecting block 4012 is fixedly connected to the bottom surface of the sub-gear 403; the third motor 4011 can be fixed to the bottom of the sub-gear 403, so that the third motor 4011 can move with the sub-gear 403. The advantage of this structure is that when the pipe needs to be bent to the left side first and then to the right side, the bending column 408 will collide with the pipe located in the middle part just above the sub-gear 403, resulting in the bending column 408 being unable to rotate from one side of the pipe to the other side. At this time, the third motor 4011 can be used to drive the adjusting gear 4010 to rotate, and the adjusting gear 4010 realizes the downward movement of the bending column 408 through the rack 409 on one side of the bending column 408, thereby avoiding interference between the bending column 408 and the pipe itself, meeting the requirement of being able to bend both sides of the pipe. Compared with the traditional single-sided bending mechanism, this structure is more flexible.

[0025] The use method and advantages of the utility model: When the easy-to-adjust automobile parts processing pipe bending machine is used, the working process is as follows:

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, the pipe to be bent is placed between the two conveying wheels 306, and the threaded rod 301 is rotated to drive the two moving boxes 302 to move. Because the threads on the threaded rod 301 are in two opposite directions, the two moving boxes 302 are moved closer or farther away from each other, thereby driving the top conveying wheel 306 to clamp the pipe, so that the anti-skid ring 3011 on the outside of the conveying wheel 306 fits with the pipe, and then the first motor 3010 is started to drive the main pulley 309 to rotate, and the main pulley 309 drives the secondary pulley 308 through the synchronous belt 308. 07 rotates, at this time, the main pulley 309 and the secondary pulley 307 drive the corresponding conveying wheel 306 on the top to rotate through the rotating shaft 305, so as to convey the pipe to the bending component 4. When the pipe is conveyed to the top of the bending component 4, the second motor 401 is started to drive the main gear 402 to rotate. When the main gear 402 rotates, it will drive the secondary gear 403 to rotate with the support shaft 404 as the axis. At this time, the bending column 408 moves with the secondary gear 403, and cooperates with the clamping and fixing of the conveying wheel 306 to be able to move the pipe in two directions close to the bending component 4. The conveying wheel 306 of the pipe is used as the end point for bending, and the pipe is conveyed toward the bending mechanism to bend different positions on the pipe. Compared with the structure of moving the bending mechanism to bend different positions of the pipe, this structure does not need to reserve a large amount of travel for the bending mechanism. Therefore, the bending machine is smaller in size and has a low manufacturing cost. The third motor 4011 is fixed at the bottom of the sub-gear 403, so that the third motor 4011 can move with the sub-gear 403. The advantage of this structure is that the pipe needs to be bent to the left first and then to the right. During side bending, the bending column 408 will collide with the pipe located in the middle part just above the sub-gear 403, causing the bending column 408 to be unable to rotate from one side of the pipe to the other side. At this time, the third motor 4011 can be used to drive the adjusting gear 4010 to rotate. The adjusting gear 4010 realizes the downward movement of the bending column 408 through the rack 409 on one side of the bending column 408, thereby avoiding interference between the bending column 408 and the pipe itself, and meeting the requirement of being able to bend from both sides of the pipe. Compared with the traditional single-sided bending mechanism, this structure is more flexible.
