Description

Technical Field

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

[0002] Metal corrugated pipe is a type of pipe with a regular wave-like shape. It is widely used in automobile exhaust pipes. During its production, it is generally formed by corrugating a whole round pipe, processing several corrugated pipes on a single round pipe, and then cutting it.

[0003] Most cutting equipment used in the current technology cuts one tube at a time. A single round tube needs to be moved multiple times before it can be cut, resulting in low cutting efficiency. Utility Model Content

[0004] The purpose of this application is to provide a cutting device for the production of metal corrugated pipes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides a cutting device for producing metal corrugated pipes, employing the following technical solution:

[0006] A cutting device for producing metal corrugated pipes includes a worktable with a cutting mechanism and a pipe-loading mechanism mounted on it. The cutting mechanism includes a protective cover, a rotating shaft, a drive motor, cutting blades, and a linear motion platform. The linear motion platform is fixed to the worktable. Shaft seats are provided on both sides of the rotating shaft, and the shaft seats are fixed to the slide of the linear motion platform. The drive motor is fixed to one side of the shaft seat and is used to drive the rotating shaft to rotate. Multiple cutting blades are provided, and the multiple cutting blades are evenly fixed on the rotating shaft. The protective cover is provided on the worktable.

[0007] The upper tube mechanism includes a rotary motor and an air expansion shaft. The rotary motor is fixed on the worktable, and the end of the air expansion shaft near the rotary motor is rotatably mounted on the worktable. The rotary motor is used to drive the air expansion shaft to rotate, and the expansion core of the air expansion shaft is set to correspond to the corrugated section in the metal bellows.

[0008] A limit ring block is fixed to one end surface of the air shaft near the rotary motor.

[0009] The length of the expansion core in the air expansion shaft is less than the length of the corrugated section in the metal bellows.

[0010] Preferably, a cylinder is provided at the bottom end of the air shaft tail, the cylinder is fixed on the worktable, and a tail support is fixed at the top end of the piston rod of the cylinder. The tail support is an arc-shaped block with a smooth inner wall.

[0011] By adopting the above technical solution, and by setting up a cylinder and a tail support, the cylinder drives the tail support to rise during cutting, providing support for the air expansion shaft, thereby improving the service life of the air expansion shaft.

[0012] Preferably, in order to facilitate the maintenance of the cutting blade in the later stage, a screw hole is provided on the rotating shaft corresponding to the position of the cutting blade, and the cutting blade is fixed on the rotating shaft by a stud.

[0013] In summary, this application includes at least one of the following beneficial technical effects: the cutting equipment for producing metal corrugated pipes is equipped with a cutting mechanism and a pipe-raising mechanism. The cutting mechanism is equipped with multiple cutting blades, and the air shaft in the pipe-raising mechanism can clamp an entire round pipe. The linear moving platform drives the high-speed rotating cutting blades to move towards one side of the round pipe, thereby completing the cutting. All corrugated pipes can be cut out at once, greatly improving cutting efficiency. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0018] This application discloses a cutting device for producing metal corrugated pipes, referring to... Figure 1-2 The system includes a workbench 1, on which a cutting mechanism 2 and a tube-raising mechanism 3 are mounted. The cutting mechanism 2 includes a protective cover 21, a rotating shaft 22, a drive motor 23, cutting blades 24, and a linear motion platform 25. The linear motion platform 25 is fixed on the workbench 1. The rotating shaft 22 has bearing seats on both sides, and the bearing seats are fixed on the slide of the linear motion platform 25. The drive motor 23 is fixed on the bearing seat on one side and is used to drive the rotating shaft 22 to rotate. The number of cutting blades 24 is set to a plurality, and the plurality of cutting blades 24 are evenly fixed on the rotating shaft 22. The protective cover 21 covers the workbench 1.

[0019] The upper tube mechanism 3 includes a rotary motor 31 and an air expansion shaft 32. The rotary motor 31 is fixed on the worktable 1. The end of the air expansion shaft 32 near the rotary motor 31 is rotatably mounted on the worktable 1. The rotary motor 31 is used to drive the air expansion shaft 32 to rotate. The expansion core of the air expansion shaft 32 is set to correspond to the corrugated section in the metal bellows. The length of the expansion core in the air expansion shaft 32 is less than the length of the corrugated section in the metal bellows.

[0020] Reference Figure 1-2 A limiting ring 4 is fixed to one end surface of the air expansion shaft 32 near the rotary motor 31. The limiting ring 4 can limit the end of the round tube so that the air expansion shaft 32 can better fix the round tube.

[0021] Reference Figure 1-2 The bottom end of the air shaft 32 is provided with a cylinder 5, which is fixed on the worktable 1. The top end of the piston rod of the cylinder 5 is fixed with a tail support 6, which is an arc-shaped block with a smooth inner wall.

[0022] By incorporating a cylinder 5 and a tail support 6, the cylinder 5 drives the tail support 6 to rise during cutting, providing support for the air shaft 32 and thus improving its service life.

[0023] Reference Figure 1 To facilitate future maintenance of the cutting blade 24, a screw hole is provided on the rotating shaft 22 corresponding to the position of the cutting blade 24, and the cutting blade 24 is fixed on the rotating shaft 22 by a stud.

[0024] The implementation principle of a cutting device for producing metal corrugated pipes according to an embodiment of this application is as follows:

[0025] During cutting, the worker places the formed whole round tube onto the air expansion shaft 32 and introduces compressed air into the air expansion shaft 32 to clamp the round tube. Then, the rotary motor 31 drives the air expansion shaft 32 to work, and the linear moving platform 25 drives the high-speed rotating cutting blade 24 to move towards one side of the round tube, thereby completing the cutting. All the corrugated tubes can be cut out in one go. Finally, the air is released from the air expansion shaft 32 and the corrugated tubes can be removed. The cutting efficiency is high.

[0026] 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.
