Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a steel wire corrugated pipe cutting machine. Background Art

[0002] With the advancement of technology and the advancement of the times, the application of corrugated pipes is becoming increasingly extensive, and market demand is becoming increasingly diverse. Against this backdrop, small-sized plastic double-wall corrugated pipes, as a key cable protection material, are becoming increasingly important. These corrugated pipes are not only lightweight and durable, but also designed with practical construction needs in mind, making them particularly suitable for cable laying projects.

[0003] In order to improve construction efficiency and simplify the subsequent cable pulling process, the manufacturer adopted an innovative method when producing these plastic double-wall corrugated pipes - pre-placing a steel wire pulling line inside the pipe; this design greatly facilitates the construction workers' operations on site, allowing them to pull the cables through the steel wire when laying them, thus completing the task more conveniently and reducing the waste of resources and environmental damage caused by repeated excavation. In addition, this method also effectively improves the construction quality and safety of the entire project, allowing the project to be carried out in a more efficient and environmentally friendly manner. This improvement reflects the manufacturer's keen insight into market changes and deep understanding of customer needs, and also reflects the trend of modern engineering technology to continue to develop in a humanized and intelligent direction.

[0004] However, existing steel wire corrugated pipe cutting machines lack an integrated length-measuring system, forcing users to rely on manual measurement to determine the length of each pipe section and then perform calculations. This process is not only time-consuming and labor-intensive, but also prone to errors due to human factors. More importantly, in the face of a changing production rhythm, these traditional cutting machines cannot be flexibly adjusted to achieve rapid and continuous precision cutting of different length specifications according to different production speeds, which undoubtedly limits the overall efficiency of the production line and the consistency of product quality. At the same time, existing cutting machines often use a V-shaped blade installed at the front end of a servo motor. The servo motor is started and rotated for one circle to drive the blade to cut ordinary plastic corrugated pipe at high speed. This places high demands on the servo motor and is unable to cut corrugated pipe with steel wire inside, affecting normal production. Utility Model Content

[0016] Preferably, the lower pad is a V-shaped pad, and the upper knife is one of an M-shaped knife, a W-shaped knife, and a V-shaped knife.

[0017] Preferably, the cutting frame includes two track grooves arranged opposite to each other along the Y direction, the lower pad and the upper knife are both arranged between the two track grooves, and the upper knife is slidably engaged with the two track grooves.

[0018] Preferably, the floating clamping device comprises a clamping support plate, and the clamping support plate is fixedly connected to the cutting device;

[0019] The clamping support plate is connected to the Y-direction clamping assembly via a Y-direction sliding assembly, and the Y-direction clamping assembly is controlled by a Y-direction driving member.

[0020] Preferably, the Y-direction sliding assembly includes a Y-direction slide rail arranged along the Y-direction and a Y-direction left slider and a Y-direction right slider adapted thereto, and both ends of the Y-direction slide rail are provided with a stopper for limiting the Y-direction left slider and the Y-direction right slider;

[0025] After adopting the above technical solution, the beneficial effects of the utility model are:

[0026] Since the present application includes a base frame; an entry sleeve, a cutting device and an exit sleeve are sequentially installed on the base frame along the direction of travel of the corrugated tube, the inner diameter of the exit sleeve is not less than the inner diameter of the entry sleeve, and the entry sleeve, the exit sleeve and the corrugated tube are all coaxially arranged; the steel wire corrugated tube enters the interior of the present application from the entry sleeve, and after being cut by the cutting device, the cut steel wire corrugated tube is discharged from the exit sleeve.

The length measuring device includes a length measuring wheel and an encoder matched therewith. The length measuring wheel extends into the interior of the entry sleeve through the length measuring through hole and abuts against the bellows. In the process of the steel wire bellows moving through the entry sleeve, the steel wire bellows drives the length measuring wheel to rotate, driving the encoder to send a pulse signal, and the travel length of the steel wire bellows is calculated by the rotation cycle of the length measuring wheel. Because the length measuring wheel and the steel wire bellows are abutted, when the travel speed of the steel wire bellows changes, the rotation speed of the length measuring wheel will also change accordingly. Therefore, the length measuring action of the steel wire bellows can be realized at different speeds, which expands the scope of application, ensures the consistency of the cutting length, and reduces the cutting error.

[0028] A synchronous moving device arranged along the X-axis is mounted on the chassis, and the cutting device is mounted on the synchronous moving device.

A floating clamping device is mounted on the cutting device, and is located upstream of the cutting device in the X-axis. The floating clamping device is used to clamp the corrugated tube before it is cut. When cutting the steel wire corrugated tube, the floating clamping device first clamps the tube. At the same time, the synchronous moving device moves at a speed consistent with the travel speed of the steel wire corrugated tube. During this process, the cutting device cuts the steel wire corrugated tube in a relatively static state, ensuring the flatness of the cut surface. At the same time, the clamping of the floating clamping device does not affect the travel of the steel wire corrugated tube. After cutting is complete, the synchronous moving device continues to clamp the steel wire corrugated tube through the floating clamping device and delivers it to the outlet sleeve to prevent it from falling, meeting the requirement for continued movement. The synchronous moving device then drives the cutting device back to its original position, preparing for the next cut. By automatically cutting the steel wire corrugated tube, the requirement for fixed-length and stable cutting is met, and fixed-length continuous cutting of different lengths at different speeds is achieved, ensuring consistent cutting length and reducing cutting errors. At the same time, it replaces the traditional manual cutting method, reducing labor intensity and improving cutting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] like Figures 1 to 4 As shown together, the present invention includes a base frame 1; an entry sleeve 2, a cutting device 3 and an exit sleeve 4 are sequentially installed on the base frame 1 along the traveling direction of the steel wire bellows 8, the inner diameter of the exit sleeve 4 is not less than the inner diameter of the entry sleeve 2, and the entry sleeve 2, the exit sleeve 4 and the steel wire bellows 8 are all coaxially arranged; the steel wire bellows 8 enters the interior of the present application from the entry sleeve 2, and after being cut by the cutting device 3, the cut steel wire bellows 8 is discharged from the exit sleeve 4. In the present application, the entry sleeve 2 and the exit sleeve 4 are coaxially arranged to ensure the accuracy of the steel wire bellows 8 when being cut.

[0046] A length measuring hole 21 is provided on the wall of the entry sleeve 2, and a length measuring device 5 is installed above the entry sleeve 2. The length measuring device 5 includes a length measuring wheel 51 and an encoder adapted thereto (blocked in the figure). The length measuring wheel 51 extends into the interior of the entry sleeve 2 through the length measuring hole 21 and abuts against the steel wire bellows 8; in the process of the steel wire bellows 8 moving through the entry sleeve 2, the steel wire bellows 8 will drive the length measuring wheel 51 to rotate, thereby causing the connected encoder to generate a pulse signal. The travel length of the steel wire bellows 8 can be calculated according to the rotation period of the length measuring wheel 51. Since the length measuring wheel 51 is in direct contact with the steel wire bellows 8, when the travel speed of the steel wire bellows 8 changes, the rotation speed of the length measuring wheel 51 will also be adjusted accordingly, thereby realizing accurate measurement of the length of the steel wire bellows 8 under different speed conditions, which not only broadens the application range of the length measuring device 5, but also ensures the consistency of the cutting length and reduces the error in the cutting process.

[0047] A synchronous moving device 6 arranged along the X direction is installed on the base frame 1, and the cutting device 3 is installed on the synchronous moving device 6. The synchronous moving device 6 is used to drive the cutting device 3 to move back and forth along the X direction. A floating clamping device 7 is installed on the cutting device 3. The floating clamping device 7 is arranged upstream of the cutting device 3 along the X direction. The floating clamping device 7 is used to clamp and fix the steel wire bellows 8 before it is cut. When cutting the steel wire bellows 8, the steel wire bellows 8 is first clamped and fixed by the floating clamping device 7. At the same time, the synchronous moving device 6 moves at a speed consistent with the travel speed of the steel wire bellows 8. During this process, the cutting device 3 cuts the steel wire bellows 8, achieving the cutting of the steel wire bellows 8 in a relatively static state, ensuring the flatness of the cut surface. At the same time, the clamping of the floating clamping device 7 will not affect the travel of the steel wire bellows 8. After the cutting is completed, the synchronous moving device 6 continues to clamp the steel wire corrugated tube 8 through the floating clamping device 7 and delivers it to the end sleeve 4 to prevent it from falling, meeting the requirement of continuing to move. The synchronous moving device 6 then drives the cutting device 3 back to its original position, preparing for the next cut. By automatically cutting the steel wire corrugated tube 8, the requirement of fixed-length and stable cutting is met, and fixed-length continuous cutting of different lengths at different speeds is achieved, ensuring the consistency of cutting length and reducing cutting errors. At the same time, it replaces the traditional manual cutting method, reducing labor intensity and improving cutting efficiency.

[0048] In the present application, the synchronous movement device 6 includes an X-direction power member 61 arranged along the X-direction. The mounting end of the X-direction power member 61 is connected to the base frame 1, and the driving end of the X-direction power member 61 is connected to the cutting device 3. An X-direction sliding assembly 62 is installed between the cutting device 3 and the base frame 1. The X-direction sliding assembly 62 includes an X-direction slide rail and a corresponding X-direction slider. The X-direction slide rail is installed on the base frame 1 along the X-direction, and the X-direction slider is installed at the bottom of the cutting device 3. Driven by the X-direction power member 61, the cutting device 3 can be driven to move back and forth along the X-direction. Preferably, the X-direction power member 61 is a cylinder, and a gas one-way throttle valve is installed at the air ports at both ends of the cylinder to adjust the extension and retraction speed of the cylinder. An electric proportional valve is also provided in the air circuit. The pressure and flow of the air circuit are continuously and proportionally controlled by an electrical signal, so that the movement speed of the cutting device 3 can be matched with the travel speed of the steel wire bellows 8, thereby achieving speed synchronization.

[0049] Among them, the cutting device 3 includes a cutting frame 31, and an X-direction sliding assembly 62 is installed between the bottom of the cutting frame 31 and the base frame 1; a lower pad 32 is fixed on the cutting frame 31, and an upper gate knife 33 is vertically slidably provided on the cutting frame 31. The upper gate knife 33 is adapted to the lower pad 32, and a cutting power part 34 is installed on the cutting frame 31 for driving the upper gate knife 33 to move back and forth vertically.

[0050] The cutting power member 34 is preferably a pneumatic cylinder. Driven by the cutting power member 34, the upper blade 33 moves downward, mates with the lower pad 32, and cuts the steel wire corrugated tube 8 located therebetween, completing the cutting operation. It should be noted that before cutting, the upper blade 33 and the lower pad 32 are vertically positioned on either side of the steel wire corrugated tube 8. Preferably, the lower pad 32 is a V-shaped pad, and the upper blade 33 is one of an M-shaped blade, a W-shaped blade, or a V-shaped blade.

[0051] The cutting frame 31 includes two rail grooves 311 arranged opposite to each other along the Y direction. The lower pad 32 and the upper knife 33 are both arranged between the two rail grooves 311 . The upper knife 33 is slidably engaged with the two rail grooves 311 .

[0052] In the present application, the floating clamping device 7 includes a clamping support plate 71, which is fixedly connected to the cutting device 3; the clamping support plate 71 is connected to the Y-direction clamping assembly 73 through the Y-direction sliding assembly 72, and the Y-direction clamping assembly 73 is controlled by the Y-direction driving member 74. The Y-direction clamping assembly 73 is used to clamp and fix the steel wire bellows 8.

[0053] Preferably, the Y-direction sliding assembly 72 includes a Y-direction slide rail arranged along the Y-direction and a Y-direction left slider and a Y-direction right slider adapted thereto, and both ends of the Y-direction slide rail are provided with a baffle 75 for limiting the Y-direction left slider and the Y-direction right slider; the Y-direction clamping assembly 73 includes a Y-direction left clamping plate 731 and a Y-direction right clamping plate 732 arranged along the Y-direction, the Y-direction left clamping plate 731 is connected to the Y-direction left slider, and the Y-direction right clamping plate 732 is connected to the Y-direction right slider; the Y-direction driving member 74 is a Y-direction cylinder, the driving end of the Y-direction driving member 74 is connected to the Y-direction left clamping plate 731, and the shell of the Y-direction driving member 74 is connected to the Y-direction right clamping plate 732.

[0054] The Y-direction driving member 74 drives the Y-left clamping plate 731 and the Y-right clamping plate 732, and first drives the Y-left clamping plate 731 to move to the left along the Y direction. When the Y-left clamping plate 731 abuts the baffle 75 on the left, the Y-direction driving member 74 drives the Y-right clamping plate 732 to move to the right until the Y-right clamping plate 732 abuts the baffle 75 on the right, thereby opening the Y-left clamping plate 731 and the Y-right clamping plate 732; when it is necessary to clamp and fix the steel wire bellows 8, the Y-direction driving member 74 drives the Y-left clamping plate 731 and the Y-right clamping plate 732 to move closer to each other, thereby completing the clamping of the steel wire bellows 8.

[0055] In the present application, a protective cover 11 is mounted on the chassis 1. The protective cover 11 is arranged outside the cutting device 3. One end of the inlet sleeve 2 extends into the interior of the protective cover 11, and one end of the outlet sleeve 4 extends out of the protective cover 11 and is located outside the protective cover 11. The protective cover 11 protects the internal cutting device 3, preventing dust from entering the cutting device 3 and protecting the surrounding personnel.

[0056] The length measuring device 5 includes a length measuring mounting seat 52 mounted on the protective cover 11. The length measuring mounting seat 52 is hingedly connected to one end of a swing rod 53. The other end of the swing rod 53 is rotatably connected to a length measuring wheel 51. The length measuring wheel 51 is synchronously connected to an encoder mounted on the swing rod 53. Under the action of its gravity, the length measuring wheel 51 can fall into the length measuring through hole 21. When the inner diameter of the inlet sleeve 2 increases to accommodate steel wire bellows 8 of different inner diameters, the length measuring wheel 51 cooperates with the swing rod 53, and can be driven by the swing rod 53 to rotate and move upward around the hinge between the length measuring mounting seat 52 and the swing rod 53, and continue to fall into the interior of the length measuring through hole 21, so that the length of steel wire bellows 8 of different inner diameters can be measured.

[0057] When the present application is in use, the moving power of the steel wire bellows 8 comes from an external forming machine. After the forming machine forms the steel wire bellows 8, it pushes the steel wire bellows 8 to continue moving, so that it enters the inlet sleeve 2, and then passes in sequence between the Y-direction left clamping plate 731 and the Y-direction right clamping plate 732, as well as between the upper gate knife 33 and the lower pad 32, and finally is discharged from the outlet sleeve 4. During this process, the length measuring wheel 51 abuts against the steel wire bellows 8 to record its length. When the length reaches the preset value, the Y-direction driving member 74 drives the Y-direction left clamping plate 731 and the Y-direction right clamping plate 732 to clamp the steel wire bellows 8, and the X-direction power member 61 drives the cutting device 3 to move along the X-direction toward the outlet sleeve 4. At the same time, the cutting power member 34 drives the upper gate knife 33 to move downward to cut the steel wire bellows 8. After the cutting is completed, the upper gate knife 33 moves upward to cut the steel wire bellows 8. The X-direction power member 61 drives the cutting device 3 to continue to move toward the outlet sleeve 4 along the X-direction, driving the downstream steel wire bellows 8 to extend into the outlet sleeve 4, completing the delivery action, and preventing the downstream steel wire bellows 8 from accumulating in the inlet sleeve 2 or the shield 11. After the delivery is completed, the Y-direction driving member 74 drives the Y-direction left clamping plate 731 and the Y-direction right clamping plate 732 to release the steel wire bellows 8, and the X-direction power member 61 drives the cutting device 3 to drive the floating clamping device 7 to reset.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
