Description

Technical Field

[0001] This utility model relates to the field of instrument panel tube beam processing technology, specifically, to a tube bending device for instrument panel tube beams. Background Technology

[0002] The instrument panel beam is the supporting skeleton of the instrument panel system. Located inside the instrument panel assembly, it has a direct impact on the strength and appearance quality of the instrument panel system.

[0003] Most existing pipe bending devices can only bend one end of the pipe. When both ends of the pipe need to be bent, the user needs to perform the operation twice, which greatly increases the number of bending steps and reduces the bending efficiency. In addition, most existing bending devices are manually pressed to bend the pipe, which greatly increases the labor intensity of the user. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe bending device for instrument panel tube beams, solving the problem that existing tube beam bending devices can mostly only bend one end of the pipe, resulting in the user needing to operate twice to bend both ends of the pipe when both ends need to be bent, which greatly increases the number of bending steps and reduces the bending efficiency. In addition, most existing bending devices rely on manual pressing to bend the pipe, which greatly increases the labor intensity of the user.

[0005] This utility model provides the following technical solution: a pipe bending device for instrument panel pipe beams, including a processing table, a bending mechanism provided on the top of the processing table, the bending mechanism consisting of a bending component for bending the pipe and a fixing component for fixing the pipe.

[0006] As a preferred embodiment of the above technical solution, the bending assembly includes a motor fixedly connected to the bottom of the processing table, two grooves formed on the top of the processing table, and two guide wheels fixedly connected to the top of the processing table. A rotating shaft is fixedly connected to the top of the motor, and a gear is fixedly connected to the top of the rotating shaft. Two racks mesh with the outer side of the gear, and a slider is fixedly connected to the bottom of the rack. A limit rod is slidably connected to the outer side of the slider, and a fixing rod is fixedly connected to the outer side of the rack. This allows the user to fix the pipe using the fixing assembly. After that, the motor can be started, and the motor drives the rotating shaft to rotate. The rotation of the rotating shaft drives the gear to rotate, and the rotation of the gear drives the two racks to move up and down through the slider and the limit rod. The movement of the racks drives the fixing rod to move, and the movement of the fixing rod drives the two second fixing blocks to move through the first and second support rods. At this time, the two second fixing blocks, with the cooperation of the two guide wheels, bend both ends of the pipe, thereby achieving the effect of bending both ends of the pipe, which greatly improves the bending efficiency of the pipe and thus improves the practicality of the device.

[0007] As a preferred embodiment of the above technical solution, the end of the rotating shaft away from the motor passes through the processing table and is fixedly connected to the gear. Two racks are distributed on both sides of the gear, and both racks mesh with the gear. The two racks have the same specifications and dimensions, and a fixing rod is fixedly connected to the outer side of each rack. Two guide wheels are staggered and have the same specifications and dimensions.

[0008] As a preferred embodiment of the above technical solution, two grooves are distributed on both sides of the gear, and the two grooves are staggered. There are two sliders and two limiting rods. The two sliders are fixedly connected to the bottom of the two racks, and the two sliders are slidably connected to the two limiting rods. The two sliders are distributed on the inner side of the two grooves, and the two limiting rods are fixedly connected to the inner side of the two grooves.

[0009] As a preferred embodiment of the above technical solution, the fixing component includes a first support rod and a second support rod fixedly connected to the top of two fixing rods, and a first fixing block fixedly connected to the top of the processing table. The top of the first support rod is fixedly connected to the second fixing block. A through hole is opened on the inner side of the second fixing block, and a threaded hole is opened on the top of the inner side of the through hole. A threaded rod is threadedly connected to the inner side of the threaded hole. A handle is fixedly connected to the top of the threaded rod, and a pressure block is fixedly connected to the bottom of the threaded rod. This allows the user to insert the pipe that needs to be bent into the through hole on the inner side of the first fixing block and the two second fixing blocks in sequence. After adjusting the length and position of the pipe, the user can then rotate the three threaded rods through the three handles. The three threaded rods will move in the cooperation of the three threaded holes. The movement of the threaded rods drives the pressure block to move. When the pressure block moves to a certain position, it will fix the pipe in the cooperation of the through hole. Then, the two ends of the pipe can be bent by the bending component, thereby improving the stability of the pipe during bending.

[0010] As a preferred embodiment of the above technical solution, there are two second fixing blocks, which are respectively fixedly connected to the top of the first support rod and the second support rod, and the two second fixing blocks have the same size and the positions of the first fixing block and the two second fixing blocks correspond to each other.

[0011] As a preferred embodiment of the above technical solution, there are three through holes, which are respectively opened on the first fixing block and the two second fixing blocks. The top of the inner side of each of the three through holes is provided with a threaded hole, and the inner side of each of the three threaded holes is threaded with a threaded rod. The top of each of the three threaded rods is fixedly connected with a handle, and the bottom of each of the threaded rods is fixedly connected with a pressure block. The three pressure blocks are respectively distributed on the inner side of the three through holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, by setting up a processing table, a bending component, and a fixing component, allows the user to insert the pipe to be bent into the through holes inside the first fixing block and two second fixing blocks in sequence. After adjusting the length and position of the pipe, the user rotates three threaded rods using three handles. The three threaded rods move with the cooperation of three threaded holes, driving the pressure block to move. When the pressure block reaches a certain position, it fixes the pipe with the cooperation of the through holes. The user can then start the motor, which drives the rotating shaft to rotate. The rotating shaft drives the gear to rotate, which in turn drives two racks to move up and down through the slider and limit rod. The rack movement drives the fixing rod, which in turn drives the two second fixing blocks to move. At this point, the two second fixing blocks, with the cooperation of two guide wheels, bend both ends of the pipe simultaneously, achieving the ability to bend the pipe at the same time, thus greatly improving the efficiency of pipe bending and significantly enhancing the practicality of the device.

[0023] With the above technical solution, when in use, the user can fix the pipe with the fixing component, and then start the motor 11. The motor 11 drives the rotating shaft 13 to rotate, the rotating shaft 13 drives the gear 14 to rotate, and the gear 14 drives the two racks 15 to move up and down through the slider 16 and the limiting rod 17. The movement of the racks 15 drives the fixing rod 18 to move, and the movement of the fixing rod 18 drives the two second fixing blocks 24 to move through the first support rod 21 and the second support rod 22. At this time, the two second fixing blocks 24 will bend the two ends of the pipe with the cooperation of the two guide wheels 19, thereby achieving the effect of bending both ends of the pipe, thus greatly improving the bending efficiency of the pipe and improving the practicality of the device.

[0024] Example 2

Then, the user can rotate the three threaded rods 27 through the three handles 28. At this time, the three threaded rods 27 will move with the cooperation of the three threaded holes 26.
