Description

Technical Field

[0001] The utility model relates to the technical field of bellows processing, in particular to a production device for tapered bellows. Background Art

[0002] Bellows are tubular elastic-sensitive components formed by connecting foldable corrugated sheets along the folding and stretching direction. After production, bellows often need to be tapered depending on their intended use. Existing methods often involve directly casting the tube into a tapered shape during injection molding, or manually applying external force to gradually shape the tube into a tapered shape. Both methods are complex, so we have developed a device for producing tapered bellows. Utility Model Content

[0003] The purpose of the utility model is to address the problems existing in the background technology and to provide a production device for a tapered corrugated pipe.

[0004] The technical solution of the utility model is: a production device for conical corrugated pipes, including a mounting frame, a base is fixed on the mounting frame, a movable seat that can be raised is provided above the base, a base column and a lifting column are fixed to the base and the movable seat respectively, a rotatable shaft is provided below the base column, the shaft includes a limit head, and the limit head is provided with a limit ring groove.

[0005] Preferably, an electric cylinder is fixedly mounted on the top of the mounting frame, and a pushing end of the electric cylinder is fixedly connected to the movable seat.

[0006] Preferably, a motor is fixedly mounted on the side of the mounting frame, an output end of the motor is fixedly connected to the shaft, and the shaft passes through the base.

[0007] Preferably, the width of the limiting ring groove is 5 mm larger than the corrugation width of the bellows, and the lifting column and the base column are of the same size.

[0008] Preferably, a bellows bracket is provided on one side of the mounting frame, and the bracket includes a frame body, and a support rod passes through the frame body.

[0009] Compared with the existing technology, the beneficial effect of the present invention is: this solution inserts the lifting column and the base column into one end of the corrugated tube, and then the movable seat drives the lifting column to rise, so that under this rising tension, this end of the corrugated tube slowly opens, thereby forming a conical shape, and the corrugations of the corrugated tube will transfer the stress of the corrugated tube when it opens through the rotating shaft in the limiting ring groove, so that the corrugations are formed. Therefore, this setting can obtain a conical corrugated tube without the need for special processing of the corrugated tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0015] Referring to the attached Figures 1-3 , a production device for a conical corrugated pipe includes a mounting frame 1. A base 2 is fixed on the mounting frame 1. A movable seat 3 that can rise is arranged above the base 2. A base column 5 and a lifting column 4 are respectively fixed on the base 2 and the movable seat 3. A rotatable shaft body 6 is arranged below the base column 5. The shaft body 6 includes a limiting head 7. The limiting head 7 is provided with a limiting ring groove 8. Through this setting, the conical processing of the corrugated pipe can be carried out. By inserting both the lifting column 4 and the base column 5 into one end of the corrugated pipe, and then the movable movable seat 3 drives the lifting column 4 to rise. Under this rising tension, this end of the corrugated pipe will slowly open, thus forming a conical shape. And the corrugations of the corrugated pipe will be in the limiting ring groove 8. Through the rotating shaft body 6, the stress during the opening of the corrugated pipe is transferred, so that the corrugated shape is formed. Therefore, this setting can obtain a conical corrugated pipe without special processing of the corrugated pipe.

[0016] Specifically, an electric cylinder 9 is fixedly installed on the top of the mounting frame 1. The pushing end of the electric cylinder 9 is fixedly connected to the moving seat 3. A motor 10 is fixedly installed on the side of the mounting frame 1. The output end of the motor 10 is fixedly connected to the shaft body 6. The shaft body 6 penetrates through the base 2. During specific operation, both the lifting column 4 and the base column 5 are inserted into one end of the corrugated pipe, and the corrugations on the pipe are located in the limiting ring groove 8. Then, start the electric cylinder 9 to drive the moving seat 3 to rise, and start the motor 10 to drive the shaft body 6 to rotate. The moving seat 3 will drive the lifting column 4 to rise. At this time, the base column 5 is in a stationary state. Thus, under the rising tension, this end of the corrugated pipe slowly opens, forming a conical shape. And the corrugations of the corrugated pipe are in the limiting ring groove 8. By driving the limiting head 7 to rotate through the rotating shaft body 6, the stress when the corrugated pipe opens is consumed, and the corrugated shape is formed.

[0017] It should be noted that, in this embodiment, the width of the limiting ring groove 8 is 5 mm larger than the width of the corrugation of the corrugated pipe, and the lifting column 4 and the base column 5 are of the same size.

[0018] It should also be noted that a corrugated pipe support is provided on one side of the mounting frame 1. The support includes a frame body 11. A support rod 12 penetrates through the frame body 11. During the processing of the corrugated pipe, the unprocessed end of the corrugated pipe is inserted into the support rod 12, making the corrugated pipe lie flat, which is conducive to processing and ensures the integrity of the cone.
