Description

Technical Field

[0001] This application relates to the technical field of metal corrugated pipe processing, and in particular to a double-end cutting and curling device for the production of metal corrugated pipes. Background Technology

[0002] Metal corrugated pipes are pipes with a regular wave-like shape. Commonly used metal corrugated pipes include those made of carbon steel and stainless steel, as well as steel-lined plastic, aluminum, and others. They are mainly used for connecting pipes to each other or connecting pipes to equipment in situations requiring a very small bending radius for non-concentric axial transmission, irregular turns, expansion and contraction, or absorbing thermal deformation of the pipeline, or in situations where it is inconvenient to install them with fixed elbows.

[0003] After the metal corrugated pipe is produced, the smooth sections at both ends need to be cut. In order to avoid the end face from scratching, the end face needs to be rolled. In the existing technology, the metal corrugated pipe is usually placed next to the cutting machine for cutting by hand, and then placed next to the rolling machine for rolling. The above actions need to be repeated twice for one metal corrugated pipe. The whole process is complicated and the production efficiency is low. Utility Model Content

[0004] The purpose of this application is to provide a double-end cutting and hemming device for the production of metal corrugated pipes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides a double-end cutting and hemming device for the production of metal corrugated pipes, employing the following technical solution:

[0006] A double-end cutting and hemming device for producing metal corrugated pipes includes a worktable. A clamping mechanism for positioning the metal corrugated pipe is provided in the middle of the worktable. A cutting mechanism and a hemming mechanism are symmetrically arranged on both sides of the clamping mechanism. An inner support rotation mechanism for clamping the metal corrugated pipe and driving it to rotate is also provided on the worktable.

[0007] The cutting mechanism includes a Y-axis servo linear slide and a cutting machine. The Y-axis servo linear slide is fixed on the worktable, and the cutting machine is mounted on the slide of the Y-axis servo linear slide.

[0008] The internal support rotation mechanism includes a three-axis moving module, a mounting frame, an air shaft, a pneumatic rotary joint, and a motor. The three-axis moving module is mounted on the worktable, the mounting frame is mounted on the three-axis moving module, one side of the pneumatic rotary joint is fixed on the mounting frame, the air shaft is rotatably connected to the mounting frame, and one end of the air shaft is connected to the pneumatic rotary joint. The motor is mounted on the mounting frame and is used to drive the air shaft to rotate.

[0009] The edge-rolling mechanism includes an X-axis servo linear slide and an edge-rolling machine mounted on the X-axis servo linear slide.

[0010] The clamping mechanism includes a base, a pressure block, a bracket, and a cylinder. The base is fixed on the workbench, the bracket is located next to the base, the cylinder is fixed on the bracket, and the pressure block is slidably connected to the bracket. The cylinder is used to drive the pressure block to move. Both the pressure block and the base surface are provided with corrugated grooves adapted to the metal corrugated pipe.

[0011] The three-axis motion module includes an X-axis motion module, a Y-axis motion module, and a Z-axis motion module, and the mounting bracket is disposed on the Z-axis motion module.

[0012] Preferably, the workbench surface has waste discharge ports on both sides of the clamping mechanism.

[0013] By adopting the above technical solution and setting up a waste discharge port, the cut metal corrugated pipe waste can fall directly from the waste discharge port, which can further reduce the labor intensity of workers.

[0014] The expansion block of the air shaft can be internally supported on the smooth inner wall of the metal bellows.

[0015] In summary, this application includes at least one of the following beneficial technical effects: the double-end cutting and hemming device for producing metal corrugated pipes is equipped with a clamping mechanism that uses the texture on the surface of the metal corrugated pipe to clamp it, so that the cutting mechanisms on both sides can cut the ends of the metal corrugated pipe. After cutting, the two end faces of the metal corrugated pipe are hemmed by the cooperation of the inner support rotation mechanism and the hemming mechanism, which can complete the cutting and hemming work in one go, greatly improving production efficiency.

[0019] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0020] This application discloses a double-end cutting and hemming device for the production of metal corrugated pipes, referring to... Figure 1-2 The system includes a workbench 1, a clamping mechanism 2 for positioning the metal corrugated pipe is provided in the middle of the workbench 1, a cutting mechanism 3 and an edge rolling mechanism 4 are symmetrically arranged on both sides of the clamping mechanism 2, and an inner support rotation mechanism 5 for clamping the metal corrugated pipe and driving it to rotate is also provided on the workbench 1.

[0021] The clamping mechanism 2 includes a base 21, a pressure block 22, a bracket 23 and a cylinder 24. The base 21 is fixed on the workbench 1, the bracket 23 is arranged next to the base 21, the cylinder 24 is fixed on the bracket 23, the pressure block 22 is slidably connected to the bracket 23, and the cylinder 24 is used to drive the pressure block 22 to move. The pressure block 22 and the base 21 are both provided with corrugated grooves that are compatible with metal corrugated pipes.

[0022] The cutting mechanism 3 includes a Y-axis servo linear slide 31 and a cutting machine 32. The Y-axis servo linear slide 31 is fixed on the worktable 1, and the cutting machine 32 is installed on the slide of the Y-axis servo linear slide 31.

[0023] The internal support rotation mechanism 5 includes a three-axis moving module 51, a mounting frame 52, an air shaft 53, a pneumatic rotary joint 54, and a motor 55. The three-axis moving module 51 is mounted on the worktable 1, and the mounting frame 52 is set on the three-axis moving module 51. The three-axis moving module 51 includes an X-axis moving module, a Y-axis moving module, and a Z-axis moving module. The mounting frame 52 is set on the Z-axis moving module. One side of the pneumatic rotary joint 54 is fixed on the mounting frame 52. The air shaft 53 is rotatably connected to the mounting frame 52, and one end of the air shaft 53 is connected to the pneumatic rotary joint 54. The motor 55 is mounted on the mounting frame 52 and is used to drive the air shaft 53 to rotate. The expansion block of the air shaft 53 can be internally supported on the smooth inner wall of the metal bellows.

[0024] The edge-rolling mechanism 4 includes an X-axis servo linear slide 41 and an edge-rolling machine 42 mounted on the X-axis servo linear slide 41.

[0025] Reference Figure 1-2 The workbench 1 has waste discharge ports 11 on both sides of the clamping mechanism 2. By setting the waste discharge ports 11, the cut metal corrugated pipe waste can fall directly from the waste discharge ports 11, which can further reduce the labor intensity of the workers.

[0026] The implementation principle of the double-end cutting and hemming device for producing metal corrugated pipes in this application embodiment is as follows:

[0027] When in use, the staff only needs to place the metal corrugated pipe in the clamping mechanism 2. When placing it, align the corrugations on the surface of the metal corrugated pipe with the corrugated grooves on the base 21. The rear cylinder 24 drives the pressure block 22 to press the metal corrugated pipe tightly on the base 21. The cutting mechanisms 3 on both sides work, and the Y-axis servo linear slide 31 drives the cutting machine 32 to move towards one side of the metal corrugated pipe, so that the excess parts at both ends of the metal corrugated pipe can be cut off.

[0028] After cutting, the three-axis moving module 51 drives the air shaft 53 to extend into the metal bellows. Air is supplied to the air shaft 53 through the pneumatic rotary joint 54, which can clamp the metal bellows from the inside. After clamping, the cylinder 24 drives the pressure block 22 to rise. The Z-axis moving module drives the air shaft 53 to move the metal bellows upward and away from the base 21. The Y-axis moving module drives the metal bellows to move to the edge rolling mechanism 4. At this time, the motor 55 drives the air shaft 53 to rotate the metal bellows. The X-axis servo linear slide 41 in the edge rolling mechanism 4 drives the edge rolling machine 42 to approach the end of the metal bellows, so that the end of the metal bellows can be edge rolled. After the edge rolling is completed, the operator can remove the metal bellows from the air shaft 53.

[0029] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
