Description

Technical Field

[0001] This application relates to the field of corrugated pipe cutting technology, and in particular to an ultra-thin-walled double-layer corrugated pipe rotary cutting device and rotary cutting processing equipment. Background Technology

[0002] Metal pipe cutting generally includes sawing, wire cutting, and laser cutting. The difficulty in cutting ultra-thin-walled double-layer corrugated pipes lies in the tendency for the inner and outer layers to delaminate during the cutting process, and the ends are prone to deformation under stress. While conventional sawing is efficient, it easily leads to delamination, failing to meet product requirements. Wire cutting is inefficient and costly, making it unsuitable for mass production. Laser cutting, while efficient and preventing delamination, produces debris that can become trapped in the corrugations, also failing to meet product requirements.

[0003] Therefore, it is urgent to propose a new technical solution to address the problems existing in the current technology. Summary of the Invention

[0020] Compared with the prior art, this application has the following beneficial effects:

[0021] 1. The ultra-thin-walled double-layer corrugated pipe rotary cutting device provided in this application includes a rotary cutting module, an infeed module, and a positioning support module. The rotary module includes a positioning fixture. During operation, the workpiece to be cut is placed in the positioning fixture and clamped for positioning. The positioning fixture is connected to a rotary drive component, which drives the positioning fixture to rotate, thereby driving the double-layer corrugated pipe to rotate axially. The infeed module consists of an infeed drive component, a lead screw, a nut, a rotary cutting blade, a rotary cutting blade holder, and a rotary cutting blade magazine. The infeed drive component drives the lead screw to rotate, and the nut on the lead screw drives the rotary cutting blade holder to move back and forth within the rotary cutting blade magazine. The positioning support module includes a support wheel with a positioning groove formed on it that matches the inner or outer wall of the pipe to be cut. When the rotary cutting blade holder moves forward to the cutting point, the rotary module is activated to cut the double-layer corrugated pipe. When the pipe to be cut is driven to rotate, and the rotary cutting blade cuts the pipe to be cut, the tip of the rotary cutting blade passes through the side wall of the pipe to be cut and engages with the positioning groove. Therefore, the ultra-thin-walled double-layer corrugated pipe rotary cutting device provided in this application supports the sidewall of the corrugated pipe with a support wheel. The surface of the support wheel is provided with a positioning groove. During rotary cutting, the tip of the rotary cutting blade is precisely embedded in the positioning groove of the support wheel. Under the interaction of the two, it can be ensured that the double-layer corrugated pipe does not separate, and the cut product end is slightly concave. The ultra-thin-walled double-layer corrugated pipe rotary cutting device provided in this application solves the problems of easy separation of the inner and outer layers of the pipe and easy deformation of the end under stress in the existing ultra-thin-walled double-layer corrugated pipe cutting process.

[0022] 2. The positioning clamp of the ultra-thin wall double-layer corrugated pipe rotary cutting device provided in this application forms a positioning cavity that matches the pipe to be cut. The positioning clamp can be a clamp composed of two halves joined together, which is conducive to the installation of the double-layer corrugated pipe. The inner wall of the positioning cavity forms a protrusion that matches the outer wall of the pipe to be cut. The protrusion matches the corrugated groove on the outer wall of the double-layer corrugated pipe. The corrugated pipe is tightly fixed in the positioning cavity and is not easy to slip out.

[0023] 3. The support wheel of the ultra-thin-walled double-layer corrugated pipe rotary cutting device provided in this application can be located inside or outside the corrugated pipe. When the support wheel is located inside the corrugated pipe, the tip of the rotary cutting blade is located outside the corrugated pipe, and the tip of the rotary cutting blade pierces the corrugated pipe and corresponds to and engages with the positioning groove on the support wheel. When the support wheel is located outside the corrugated pipe, the tip of the rotary cutting blade is located inside the corrugated pipe, and the tip of the rotary cutting blade pierces the corrugated pipe and corresponds to and engages with the positioning groove on the support wheel.

[0041] Example 1

[0042] This application provides an ultra-thin-walled double-layer corrugated pipe rotary cutting device. See also... Figure 1 The ultra-thin-walled double-layer corrugated pipe rotary cutting device basically includes a rotating module A, a cutting module B, and a positioning support module D. Among them, the rotating module A includes a positioning fixture 15 and a rotating drive assembly for driving the positioning fixture 15 to rotate. A positioning cavity is formed on the positioning fixture 15, and the positioning cavity is adapted to and connected to the pipe to be cut.

[0043] The feed module B includes a feed drive assembly, a transmission assembly, and a tool assembly. The transmission assembly includes a lead screw 21 connected to the feed drive assembly and a nut 18 mounted on the lead screw 21. The tool assembly includes a rotary cutting tool magazine 19, a rotary cutting tool holder 16 connected to the nut 18, and a rotary cutting blade 1 mounted on the rotary cutting tool holder 16. The lead screw 21 is located in the rotary cutting tool magazine 19. When the lead screw 21 is driven to rotate, the nut 18 drives the rotary cutting tool holder 16 to move back and forth in the rotary cutting tool magazine 19.

[0044] The positioning support module D includes a bracket 26, a support shaft 24 mounted on the bracket 26, and a support wheel 23 mounted on the support shaft 24. The support wheel 23 has a positioning groove 30 that is adapted to the inner or outer wall of the pipe to be cut. The support wheel 23 abuts against the pipe to be cut through the positioning groove 30. When the pipe to be cut is driven to rotate and the rotary cutting blade 1 cuts the pipe to be cut, the tip of the rotary cutting blade 1 passes through the side wall of the pipe to be cut and engages with the positioning groove 30.

[0045] The ultra-thin-walled double-layer corrugated pipe rotary cutting device provided in this application can place the workpiece to be cut into the positioning fixture 15 for clamping and positioning during the cutting operation. The positioning fixture 15 is connected to the rotary drive assembly, which drives the positioning fixture 15 to rotate, thereby driving the double-layer corrugated pipe 14 to rotate axially. The feed module B consists of a feed drive assembly, a lead screw 21, a nut 18, a rotary cutting blade 1, a rotary cutting blade holder 16, and a rotary cutting blade magazine 19. The feed drive assembly drives the lead screw 21 to rotate, and the lead screw 21... The nut 18 drives the rotary cutting blade holder 16 to move back and forth within the rotary cutting blade magazine 19. The positioning support module D includes a support wheel 23, on which a positioning groove 30 is formed to match the inner or outer wall of the pipe to be cut. When the rotary cutting blade holder 16 moves forward to the cutting point, the rotation module A is activated to cut the double-layer corrugated pipe 14. When the pipe to be cut is driven to rotate, and the rotary cutting blade 1 cuts the pipe to be cut, the tip of the rotary cutting blade 1 passes through the side wall of the pipe to be cut and engages with the positioning groove 30. Therefore, the ultra-thin wall double-layer corrugated pipe rotary cutting device provided in this application supports the side wall of the corrugated pipe through the support wheel 23. The support wheel 23 has a positioning groove 30 on its surface. During rotary cutting, the tip of the rotary cutting blade 1 is precisely embedded in the positioning groove 30 of the support wheel 23. Under the interaction of the two, it can be ensured that the double-layer corrugated pipe 14 does not separate into layers, and the cut product port is slightly concave. The ultra-thin-walled double-layer corrugated pipe rotary cutting device provided in this application solves the problems of easy delamination of the inner and outer layers of the pipe and easy deformation of the port under stress in the existing ultra-thin-walled double-layer corrugated pipe cutting process.

[0046] In one embodiment, the ultra-thin-walled double-layer corrugated pipe rotary cutting device provided in this application may further include an auxiliary clamping module C. See also Figure 2The feed module B and the positioning support module D are fixedly connected by an auxiliary clamping module C. When the auxiliary clamping module C is moved to the target position, the feed module B connected to it is moved to the target cutting position, and the positioning support module D connected to it is moved to the target support position. It should be noted that the auxiliary clamping module C of the ultra-thin wall double-layer corrugated pipe rotary cutting device provided in this application is not an indispensable module. In one embodiment, the bracket 26 of the positioning support module D can be movably mounted on the equipment frame to achieve fixed support for the support wheel 23. The rotary cutting blade magazine 19 of the feed module B can be movably mounted on the equipment frame. When it is necessary to adjust the position of the positioning support module D and the feed module B according to the positioning fixture 15, the positioning support module D and the feed module B can be adjusted separately. The auxiliary clamping module C can realize the synchronous positioning and movement of the positioning support module D and the feed module B.

[0047] In one embodiment, see Figure 3 The positioning cavity on the positioning fixture 15 of the rotating module A is a cylindrical cavity adapted to the shape of the pipe to be cut; the pipe to be cut is a double-layer corrugated pipe 14, and a protrusion adapted to the outer wall of the pipe to be cut is formed on the inner wall of the positioning cavity. The protrusion is adapted to the corrugated groove on the outer wall of the double-layer corrugated pipe 14. The positioning fixture 15 of the ultra-thin-walled double-layer corrugated pipe 14 rotary cutting device provided in this application forms a positioning cavity adapted to the pipe to be cut. The positioning fixture 15 can be a fixture composed of two halves joined together, which is conducive to the installation of the double-layer corrugated pipe 14. A protrusion adapted to the outer wall of the pipe to be cut is formed on the inner wall of the positioning cavity. The protrusion is adapted to the corrugated groove on the outer wall of the double-layer corrugated pipe 14. The corrugated pipe is tightly fixed in the positioning cavity and is not easy to slip out. In the actual processing, the structure of the positioning fixture 15 is adjusted according to the shape of the bellows, so that the protrusion on the positioning fixture 15 is precisely locked in the corrugated groove cavity of the bellows, thus fixing the product and preventing the bellows from moving during cutting and causing the cutting dimensions to be unqualified.

[0048] In one embodiment, the rotary drive assembly includes a drive motor, the power output end of which is connected to the positioning fixture 15. The positioning fixture 15 rotates under the drive of the drive motor, and drives the double-layer corrugated pipe 14 inside it to rotate along the central axis of the positioning cavity.

[0049] In one embodiment, see Figure 4 The feed drive assembly of the feed module B includes a handwheel 5, which includes a handwheel 5 handle. A shaft hole is formed on the handwheel 5, and a lead screw 21 is fixedly installed in the shaft hole. When the handwheel 5 is driven to rotate, the lead screw 21 rotates with the handwheel 5.

[0050] In one embodiment, see further. Figure 4The rotary cutting blade magazine 19 has an inner cavity, in which the lead screw 21 and nut 18 are disposed. The nut 18 is sleeved on the lead screw 21. A sliding groove is provided on the inner wall of the inner cavity, and a slider is disposed in the sliding groove. The slider is connected to the outer wall of the nut 18. When the lead screw 21 is driven to rotate, the nut 18 moves back and forth along the central axis of the lead screw 21. One end of the rotary cutting blade holder 16 forms the mounting position for the rotary cutting blade 1, and the other end is connected to the nut 18. When the nut 18 is driven to reciprocate along the central axis of the lead screw 21, the rotary cutting blade 1 is driven to move closer to or away from the pipe to be cut. The rotary cutting blade 1 has a mounting hole, in which a rotary cutting pin 17 passes. The rotary cutting blade 1 is fastened to the rotary cutting blade holder 16 through the rotary cutting pin 17. One end of the rotary cutting pin 17 is fitted with an elastic washer 2 and a hexagonal nut. In actual installation, the rotary cutting blade 1 is connected to the rotary cutting blade holder 16 via deep groove ball bearings 9 and 10, elastic washer 2, and rotary cutting pin 17. The blade holder is then installed into the rotary cutting blade magazine 19 via screw 21, blade magazine cover 20, and other components, and a handwheel 5 is installed. During operation, turning the handwheel 5 rotates the screw 21, which in turn drives the rotary cutting blade holder 16 to move back and forth within the rotary cutting blade magazine 19 via nut 18.

[0051] In one embodiment, see Figure 5 One end of the bracket 26 is fastened to the support shaft 24, and the other end of the support shaft 24 forms an installation position that is compatible with the support wheel 23.

[0052] In a specific application example, see Figure 9 A positioning groove 30 adapted to the inner wall of the pipe to be cut can be provided on the outer surface of the support wheel 23. When the pipe to be cut is rotary cut, the rotary cutting blade 1 is located outside the pipe to be cut, the support wheel 23 is located inside the pipe to be cut and abuts against the inner wall of the pipe to be cut, and the support wheel 23 is close to the tip of the rotary cutting blade 1. When the pipe to be cut is driven to rotate, the rotary cutting blade 1 of the feed module B inserts into the side wall of the pipe to be cut, and the tip of the rotary cutting blade 1 is correspondingly inserted into the positioning groove 30 on the outer surface of the support wheel 23. The positioning groove 30 forms a limit for the rotary cutting blade 1. The positioning groove 30 can be a V-shaped groove.

[0053] In another specific application example, a positioning groove 30 adapted to the outer wall of the pipe to be cut can be provided on the outer surface of the support wheel 23. When the pipe to be cut is rotary cut, the rotary cutting blade 1 is located inside the pipe to be cut, the support wheel 23 is located outside the pipe to be cut and abuts against the outer wall of the pipe to be cut, and the support wheel 23 is close to the tip of the rotary cutting blade 1. When the pipe to be cut is driven to rotate, the rotary cutting blade 1 of the feed module B inserts into the side wall of the pipe to be cut, and the tip of the rotary cutting blade 1 is inserted into the positioning groove 30 on the outer surface of the support wheel 23. The positioning groove 30 forms a limit for the rotary cutting blade 1.

[0054] In one embodiment, see further. Figure 5 The bracket 26 can be an L-shaped structure. One end of the bracket 26 is equipped with a support wheel 23, and the other end is connected to the auxiliary clamping module C. A connecting plate is provided on the outer wall of the rotary cutting tool magazine 19, and the feed module B is connected to the auxiliary clamping module C through the connecting plate.

[0055] In one embodiment, see Figure 2 and Figure 10 The auxiliary clamping module C includes a pressure plate 27, a support plate 28, and a clamping handle 29. The support plate 28 and the pressure plate 27 are arranged at intervals relative to each other. A connecting plate is installed between the support plate 28 and the pressure plate 27 and is fastened to the support plate 28 and the pressure plate 27 by screws. A bracket 26 is installed between the support plate 28 and the pressure plate 27 and is fastened to the support plate 28 and the pressure plate 27 by screws. The clamping handle 29 is installed on the pressure plate 27.

[0056] In one embodiment, see Figure 6 , 7 8, Figure 6 In the process, the feed module B and the positioning support module D are connected by the auxiliary clamping module C. The feed module B and the positioning support module D are in the pre-cutting preparation position. During cutting, the feed module B and the positioning support module D need to be moved to the target position respectively, such as... Figure 7 After the feed module B moves to the target cutting position, the handwheel 5 needs to be turned to move the tip of the rotary cutting blade 1 to the cutting point, such as... Figure 8 At this point, the drive motor can be started to rotate the double-layer corrugated pipe 14 and complete the cutting.

[0057] The support wheel 23 of the ultra-thin-walled double-layer corrugated pipe rotary cutting device provided in this application can be disposed inside or outside the corrugated pipe. When the support wheel 23 is disposed inside the corrugated pipe, the tip of the rotary cutting blade 1 is located outside the corrugated pipe, and the tip of the rotary cutting blade 1 penetrates the corrugated pipe and corresponds to and engages with the positioning groove 30 on the support wheel 23. When the support wheel 23 is disposed outside the corrugated pipe, the tip of the rotary cutting blade 1 is located inside the corrugated pipe, and the tip of the rotary cutting blade 1 penetrates the corrugated pipe and corresponds to and engages with the positioning groove 30 on the support wheel 23. Therefore, this ultra-thin-walled double-layer corrugated pipe rotary cutting device can adapt to corrugated pipes of different diameters.

It includes a feeding device, a discharging device, a conveying device, and an ultra-thin-walled double-layer corrugated pipe rotary cutting device. The feeding device is used to feed the ultra-thin-walled double-layer corrugated pipe to the rotary cutting device, which then performs rotary cutting on the double-layer corrugated pipe 14 fed onto it. The discharging device is used to clamp and discharge the cut double-layer corrugated pipe 14, and the conveying device is used to transport the discharged double-layer corrugated pipe 14 to a subsequent processing station.

[0060] In one embodiment, the feeding device may include a clamping feeding mechanism that feeds the double-layer corrugated pipe 14 into the positioning fixture 15 of the ultra-thin-walled double-layer corrugated pipe rotary cutting device. The unloading device may include a clamping unloading mechanism that picks up the cut double-layer corrugated pipe 14 from the positioning fixture 15 and places the picked-up double-layer corrugated pipe 14 into a conveying device. The conveying device may include a conveying mechanism, such as a conveyor belt and a belt drive assembly.

[0061] The ultra-thin-walled double-layer corrugated pipe rotary cutting equipment provided in this embodiment cuts the double-layer corrugated pipe 14 using an ultra-thin-walled double-layer corrugated pipe rotary cutting device. This device supports the sidewall of the corrugated pipe using a support wheel, the surface of which has a positioning groove. During rotary cutting, the tip of the rotary cutting blade is precisely embedded in the positioning groove of the support wheel. This interaction ensures that the double-layer corrugated pipe does not separate, and the cut product's end is slightly concave. Therefore, the ultra-thin-walled double-layer corrugated pipe rotary cutting equipment provided in this application solves the problems of easy separation of the inner and outer layers and easy deformation of the end under stress in existing ultra-thin-walled double-layer corrugated pipes during the cutting process, and also achieves automated production of double-layer corrugated pipe cutting, loading, unloading, and feeding.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0063] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
