Description

Technical Field

[0001] The invention relates to the technical field of pipe processing in mechanical technology, in particular to a bidirectional bending mechanism for pipes. Background Art

[0002] In the prior art, in the process of processing pipes, the pipes are basically required to be bent. In the prior art, the bending mechanism for pipes usually has a relatively simple structure.

[0003] For example, the patent document with publication (announcement) number: CN 110538901 A discloses "a pipe bending device", and the technical solution includes: a fixed seat, a clamping and pushing device, including a driving device arranged on the fixed seat and a transmission component connected to the driving device, and the transmission component is connected to the bending disk; a compression buffer device, which is arranged on one side of the bending disk, and the compression buffer device includes a fixed platform arranged on the fixed seat, an elastic compression device and a pipe placement plate arranged on the fixed platform, and a groove matching the elastic compression device is arranged on the fixed platform, and the elastic compression device is arranged in the groove and protrudes from the fixed platform in a natural state. The elastic compression device is compressed to the shortest, and the elastic compression device shrinks to be flush with the fixed platform.

[0004] The main advantage of this technical solution is the use of an elastic compression device, which can play a good buffering role, protect the pipe, and prevent the pipe from being squeezed and deformed to produce defective products.

[0005] However, in the above technical solution, the elastic compression device can only realize the bending of the pipe in one direction. In the actual bending process, considering the shape of the bend, the number of bends, etc., it is usually necessary to bend the pipe from different directions. The above technical solution and the existing technical solutions basically cannot realize the bidirectional bending function.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a bidirectional bending mechanism for pipes that can be bent in different directions. Summary of the invention

[0007] The purpose of the present invention is to provide a bidirectional bending mechanism for a pipe in view of the deficiencies in the prior art; the technical solution is as follows:

[0008] A bidirectional bending mechanism for pipes comprises a clamping workbench, a bending workbench is continuously installed on the right side of the clamping workbench, and the height of the bending workbench is arranged lower than that of the clamping workbench, a clamping fixture is also correspondingly installed on the left side of the clamping workbench, which can clamp and fix the pipe to be bent, and the pipe extends toward the bending workbench accordingly, and two inner slide grooves are correspondingly arranged on the right side of the clamping workbench, the two inner slide grooves are respectively arranged on both sides of the pipe after clamping and fixing, and corresponding sliders are arranged in the two inner slide grooves, and bidirectional wheels are installed on the sliders through support rods.

[0009] A movable plate is arranged on the bending workbench, and a driving mechanism for driving the movable plate to move is also arranged on one side of the bending workbench. The driving direction of the driving mechanism is arranged perpendicular to the extension direction of the pipe. The left end of the movable plate is close to the right end of the clamping workbench, and two outer slide grooves are arranged correspondingly on the movable plate. The setting positions of the two outer slide grooves correspond to the setting positions of the two inner slide grooves. The slider in the inner slide groove can be moved to the outer slide groove accordingly, and then follow the movable plate to move accordingly.

[0010] Furthermore, the thickness of the movable plate is set so that the upper end surface of the movable plate is flush with the upper end surface of the clamping workbench.

[0011] Furthermore, the inner slide groove and the outer slide groove have the same groove width, the inner slide groove extends to the right end of the clamping workbench and is open, and the outer slide groove extends to the left end of the movable plate and is also open, so that the slider moves into the inner slide groove or the outer slide groove.

[0012] Furthermore, the inner slide groove and the outer slide groove are both embedded structures, and the slider is configured as a square slider embedded in the inner slide groove or the outer slide groove.

[0013] Furthermore, a vertically bent root groove is extended at the right end position of the outer slide groove, and the sliding block finally enters the root groove and is fixed after entering the outer slide groove.

[0014] Furthermore, a slide rail mechanism is installed between the movable plate and the bending workbench; the moving direction of the movable plate is correspondingly limited by the slide rail mechanism, so that the movable plate can only move perpendicular to the extension direction of the pipe.

[0015] Furthermore, an arc-shaped clamping groove is arranged on the wheel body of the bidirectional wheel, the pipe is clamped in the clamping groove, and each bidirectional wheel can rotate accordingly.

[0016] Beneficial effects: The present invention has the following beneficial effects:

[0017] (1) When the present invention is used in practice, the two-way wheels on both sides can be used as fulcrums for bending and as power for bending. If the pipe is to be bent downward, the slider inside the lower outer slide groove does not move, and the slider inside the upper outer slide groove moves to the right into the inner slide groove of the movable plate. After the movable plate moves downward, the two-way wheels located on the upper side are used as power to bend the entire pipe downward, while the two-way wheels located on the lower side are used as fulcrums to support the pipe, so that the entire pipe can be bent. If the pipe is to bend upward, it is only necessary to move the two-way wheels below into the movable plate, and the two-way wheels above remain in place. The bending direction can be changed as needed during complex bending. The overall structural design is very ingenious and reasonable, and it is easy to use.

[0018] (2) In the present invention, the thickness of the movable plate and the positions of the inner and outer slide grooves are set so that the slider can be easily moved into the inner and outer slide grooves, and the inner and outer slide grooves are both set as embedded structures, so that the slider can be embedded in the slide grooves and will not fall off. The positions of the movable plate and the bending workbench can also be set closely, leaving a gap in the middle, and the overall structure is very reasonable;

[0019] (3) In the present invention, the slide rail mechanism is provided to facilitate the movement of the movable plate and limit the position of the movable plate. In addition, in the present invention, a clamping groove is provided on the wheel body of the two-way wheel for clamping the pipe. The pipe passes through the clamping groove, and each two-way wheel can rotate. Because when the two-way wheel is used as a fulcrum and during the bending process, the contact position between the two-way wheel and the pipe will change accordingly. After the two-way wheel is set to be rotatable, the two-way wheel will rotate as the position changes during bending, and the bending is more reasonable. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] When the present invention is used in practice, the two-way wheels on both sides can be used as fulcrums for bending and can also be used as the power for bending; Figure 4 As shown, if the pipe needs to be bent downward, the slider inside the lower outer slide groove does not move, and the slider inside the upper outer slide groove moves horizontally to the right into the inner slide groove of the movable plate. After the movable plate moves downward, the two-way wheels located at the top are used as power to bend the entire pipe downward, and the two-way wheels located at the bottom are used as fulcrums to support the pipe, so that the entire pipe can be bent; and if the pipe needs to be bent upward, it is only necessary to move the two-way wheels below into the movable plate, and the two-way wheels above remain in place.
