[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0020] like Figure 1 and 2As shown, a double-head cutting device for corrugated pipes includes a base 1 and a support base 2. The support base 2 is fixedly connected to the top of the base 1. A groove 21 is provided at the top of the support base 2. A cutting structure 3 is symmetrically provided at the top of the base 1. The two cutting structures 3 are respectively provided at the two ends of the support base 2. The cutting structure 3 includes a base 31 and a driving assembly 33. An arc groove 32 is provided at the top of the base 31. The base 31 is fixedly connected to the top of the base 1. The driving assembly 33 is provided at the top of the base 31. An extrusion assembly 34 for extruding the pipe head is provided at the top of the driving assembly 33. A cutting assembly 35 is fixedly connected to the top of the driving assembly 33. The cutting assembly 35 passes through the extrusion assembly 34.

[0021] According to the above structure, when in use, the corrugated tube is placed on the groove 21, and the two ends of the corrugated tube are placed on two bases 31 respectively. When cutting, the extrusion assembly 34 and the cutting assembly 35 are driven to descend by the driving assembly 33. The extrusion assembly 34 first contacts the corrugated tube, and as the driving assembly 33 continues to descend, the extrusion assembly 34 presses the corrugated tube head. As the driving assembly 33 continues to descend, the cutting assembly 35 cuts the corrugated tube head. The corrugated tube head can be fixed and cut by contracting the driving assembly 33. The operation steps are simple and the cutting efficiency is improved.

[0022] like Figure 2-4 As shown, the driving assembly 33 includes a top plate 331, and an electric push rod 332 is symmetrically provided at the bottom end of the top plate 331, and the bottom end of the electric push rod 332 is fixedly connected to the top end of the base 1. The extrusion assembly 34 includes an arc-shaped pressure plate 341, and the surface of the arc-shaped pressure plate 341 is symmetrically provided with through holes, and a slide rod 342 is slidably connected inside the through hole. The top end of the slide rod 342 is fixedly connected to the bottom end of the top plate 331, and the side wall of the slide rod 342 is provided with a spring 344. The two ends of the spring 344 are respectively fixedly connected to the top end of the arc-shaped pressure plate 341 and the bottom end of the top plate 331, and the bottom end of the slide rod 342 is fixedly connected to the circular plate 343.

[0023] According to the above structure, when the bellows head is tightened, the two electric push rods 332 are contracted to drive the top plate 331 to descend, and the arc pressure plate 341 descends as the top plate 331 descends. When the bottom end of the arc pressure plate 341 contacts the bellows, the arc pressure plate 341 stops descending. At this time, the top plate 331 continues to descend and compresses the spring 344. After being compressed, the spring 344 squeezes the arc pressure plate 341, thereby tightening and fixing the bellows.

[0024] like Figure 2 and 4As shown, the cutting assembly 35 includes a cutter 351, the top of the cutter 351 is fixedly connected to a connecting plate 352, the top of the connecting plate 352 is symmetrically fixedly connected to a connecting rod 353, the top of the connecting rod 353 is fixedly connected to the bottom end of the top plate 331, a cutting groove 321 is provided in the middle of the arc groove 32, the cutter 351 passes through the arc pressure plate 341, and the bottom end of the cutter 351 is provided corresponding to the cutting groove 321.

[0025] According to the above structure, as the top plate 331 descends, the arc-shaped pressure plate 341 presses the corrugated tube head, the top plate 331 continues to descend, and the cutter 351 also continues to descend. After the cutter 351 descends and contacts the corrugated tube, the corrugated tube is cut. After the cutting is completed, the electric push rod 332 is extended, and the top plate 331 drives the connecting rod 353, the connecting plate 352 and the cutter 351 to lift up first. When the top end of the circular plate 343 contacts the bottom end of the arc-shaped pressure plate 341, the arc-shaped pressure plate 341 is lifted, so that the cut corrugated tube can be collected and the corrugated tube to be cut can be placed.

[0026] The working principle of the present invention is as follows: when in use, the bellows is placed on the groove 21, and the two ends of the bellows are placed on the two bases 31 respectively. When the bellows head is pressed, the two electric push rods 332 are contracted to drive the top plate 331 to descend, and the arc-shaped pressure plate 341 descends as the top plate 331 descends. When the bottom end of the arc-shaped pressure plate 341 contacts the bellows, the arc-shaped pressure plate 341 stops descending. At this time, the top plate 331 continues to descend and compresses the spring 344. The spring 344 is compressed and squeezes the arc-shaped pressure plate 341, thereby pressing and fixing the bellows. As the top plate 331 continues to descend, the cutter 351 also continues to descend. After the cutter 351 descends and contacts the bellows, the bellows is cut. After the cutting is completed, the electric push rod 332 is extended, and the top plate 331 drives the connecting rod 353, the connecting plate 352 and the cutter 351 to be lifted upward first. When the top end of the circular plate 343 contacts the bottom end of the arc-shaped pressing plate 341, the arc-shaped pressing plate 341 is lifted, so that the cut bellows can be collected and the bellows to be cut can be placed.
