Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and in particular relates to a cutting device for producing cable protection pipes. Background Technology

[0002] Cable protection pipe cutting devices are automated or semi-automated equipment specifically designed for the precise cutting of cable protection pipes. Their core function is to ensure that the cut of the protection pipe meets engineering requirements through efficient and precise cutting, thus providing a reliable foundation for subsequent cable laying, connection, and protection. Existing pipe cutting devices use two sets of vertical plates to clamp and fix one end of the pipe. This design effectively prevents displacement of the pipe during cutting; however, it still has significant shortcomings: when multiple segment cuts are required, operators need to frequently loosen and tighten the clamping plates, making the operation cumbersome, consuming a lot of time and effort, and reducing work efficiency. Furthermore, after each re-clamping of the pipe, a measuring ruler must be used to accurately measure the length of the protruding pipe segment to ensure that the cutting length of each segment meets the standard requirements. Summary of the Invention

[0003] In view of this, the present invention aims to propose a cutting device for producing cable protection pipes, so as to solve the problem that after the current sawing equipment has completed the fixing of the pipe, if multiple cuts are required, the operator has to repeatedly perform the clamping and loosening operation of the pipe. This not only consumes a lot of time and manpower, but may also cause the pipe positioning deviation due to frequent loading and unloading, affecting the cutting accuracy and production efficiency.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A cutting device for producing cable protection pipes includes a working platform, a cutting mechanism, a first clamping mechanism, and a second clamping mechanism. The cutting mechanism includes an electric telescopic rod and a rotary motor. The electric telescopic rod is supported and fixed on the working platform by a support frame. A mounting rod is fixedly connected to the piston rod of the electric telescopic rod, and a rotating rod is rotatably connected to the mounting rod. A saw blade is fixedly mounted on the rotating rod. A first pulley is fixedly connected to one end of the rotating rod, and an annular belt is fitted on the first pulley. A second pulley is fitted inside the annular belt and is fixedly connected to the output end of the rotary motor. The rotary motor is mounted and fixed on the piston rod of the electric telescopic rod via a fixed base. The first clamping mechanism includes a sliding cavity, a first clamping element, and a second clamping element. The second clamping mechanism comprises two sets of third clamping components. The first clamping component is fitted with a first anti-slip rubber collar and is rotatably connected to a rotating bracket. A sliding rod is fixedly connected to one side of the rotating bracket and slidably connected within a sliding cavity, which is bolted to the work platform. The second clamping component is disc-shaped and has a second anti-slip rubber collar fitted on its side. The center of the second clamping component is rotatably connected to a first rotating support rod, which is fixedly connected to the work platform. The second clamping mechanism also includes a third clamping component, of which there are two sets. Each third clamping component is fitted with a third anti-slip rubber collar, and the center of the third clamping component is rotatably connected to a second rotating support rod, which is also fixedly connected to the work platform.

[0006] Furthermore, the longitudinal sections of both the first clamping member and the third clamping member are I-shaped; and the distance between the side wall of the first clamping member and the side wall of the second clamping member is equal to the distance between the side walls of the two sets of third clamping members.

[0007] Furthermore, a limit frame is welded onto the support frame, and the limit frame abuts against one side of the rotating rod.

[0008] Furthermore, the sliding rod is provided with an annular boss, and a pressure spring is sleeved on the sliding rod, with both ends of the pressure spring supported on the annular boss and the inner wall of the sliding cavity, respectively.

[0009] Furthermore, the second clamping component has a circumference of two meters and is marked with annular scale lines, including large and small scale lines.

[0010] Furthermore, a first sprocket is rotatably connected to the second rotating support rod. The first sprocket is fixedly connected to the third clamping member through a fixed connecting block. An annular chain is sleeved on the first sprocket, and a second sprocket is sleeved inside the annular chain.

[0011] Furthermore, the center of the second sprocket is rotatably connected to the third rotating support rod, the third rotating support rod is fixedly connected to the working platform, a sleeve is sleeved on the third rotating support rod, the second sprocket is supported above the sleeve, and a drive disc is fixedly installed on the second sprocket by bolts, and a handle is provided on one side of the drive disc.

[0012] Compared with the prior art, the cutting device for producing cable protection pipes described in this utility model has the following advantages:

[0013] This invention designs a collaborative working mode between a first clamping mechanism and a second clamping mechanism to construct an adjustable pipe fixing system. During multi-segment sawing operations, the second clamping mechanism can clamp and deliver the pipe, maintaining a stable clamping force while adjusting the extension length of the pipe. Meanwhile, the second clamping component of the first clamping mechanism is marked with an annular scale line. This design allows for a relatively accurate measurement of the pipe delivery length, thus providing a convenient and reliable reference for controlling the sawing length of each pipe segment, significantly improving the efficiency of pipe cutting.

[0026] As attached Figure 1 To be continued Figure 5As shown:

[0027] This utility model provides a cutting device for producing cable protection pipes, including a working platform 1, a cutting mechanism, a first clamping mechanism, and a second clamping mechanism; the cutting mechanism includes an electric telescopic rod 2 and a rotary motor 10; the electric telescopic rod 2 is supported and fixed on the working platform 1 by a support frame 3, a mounting rod 4 is fixedly connected to the piston rod of the electric telescopic rod 2, a rotating rod 5 is rotatably connected to the mounting rod 4, a saw blade 6 is fixedly mounted on the rotating rod 5, a first pulley 7 is fixedly connected to one end of the rotating rod 5, an annular belt 8 is sleeved on the first pulley 7, and a second pulley 9 is sleeved inside the annular belt 8, the second pulley 9 is fixedly connected to the output end of the rotary motor 10, and the rotary motor 10 is mounted and fixed on the piston rod of the electric telescopic rod 2 by a fixing seat 11; the first clamping mechanism includes a sliding cavity 17, a first clamping member 13, and a second clamping member 20; wherein The first clamping member 13 is fitted with a first anti-slip rubber collar 14. The first clamping member 13 is rotatably connected to the rotating bracket 15. A sliding rod 16 is fixedly connected to one side of the rotating bracket 15. The sliding rod 16 is slidably connected in the sliding cavity 17. The sliding cavity 17 is fixed to the working platform 1 by bolts. The second clamping member 20 is disc-shaped. A second anti-slip rubber collar 21 is fitted on the side of the second clamping member 20. The center of the second clamping member 20 is rotatably connected to the first rotating support rod 22. The first rotating support rod 22 is fixedly connected to the working platform 1. The second clamping mechanism includes a third clamping member 24. There are two sets of third clamping members 24. Each third clamping member 24 is fitted with a third anti-slip rubber collar 25. The center of the third clamping member 24 is rotatably connected to the second rotating support rod 23. The second rotating support rod 23 is also fixedly connected to the working platform 1.

[0028] Among them, such as Figure 3 and Figure 5 As shown, the longitudinal sections of the first clamping member 13 and the third clamping member 24 are both I-shaped; and the distance between the side wall of the first clamping member 13 and the side wall of the second clamping member 20 is equal to the distance between the side walls of the two sets of third clamping members 24, which is approximately equal to the diameter of the pipe; the pipe can be placed in the U-shaped gap between the first clamping member 13 and the second clamping member 20 for support, and is clamped on both sides by the first anti-slip rubber collar 14 and the second anti-slip rubber collar 21; the pipe is placed in the U-shaped gap between the two sets of third clamping members 24 for support, and is clamped on both sides by the third anti-slip rubber collar 25.

[0029] Among them, such as Figure 2As shown, a limit frame 12 is welded on the support frame 3, and the limit frame 12 abuts against one side of the rotating rod 5. During the process of the saw blade 6 continuously cutting into the pipe, the pipe also generates a reaction force on the saw blade 6, which can easily cause the piston rod of the electric telescopic rod 2 to vibrate, resulting in a rough pipe cut and making it inconvenient to perform docking work. In order to ensure that the cutting work is carried out smoothly, the limit frame 12 can be used to abut against one side of the rotating rod 5 to counteract the above reaction force.

[0030] Among them, such as Figure 4 As shown, the sliding rod 16 is provided with an annular boss 18, and a pressure spring 19 is sleeved on the sliding rod 16. The two ends of the pressure spring 19 are respectively supported on the annular boss 18 and the inner wall of the sliding cavity 17. The pressure spring 19 applies pressure to the annular boss 18, thereby increasing the clamping force of the first clamping member 13 and the second clamping member 20 on the pipe, and the first anti-slip rubber sleeve 14 and the second anti-slip rubber sleeve 21 prevent the pipe from sliding in the gap.

[0031] Among them, such as Figure 3 As shown, the second clamping member 20 has a circumference of two meters and is marked with annular scale lines, including large scale lines and small scale lines. There are ten sets of large scale lines, and there are four sets of small scale lines between every two sets of adjacent large scale lines. The arc length between every two sets of adjacent small scale lines is four centimeters. When the pipe is delivered in the gap between the first clamping member 13 and the second clamping member 20, the second clamping member 20 rotates around the first rotating support rod 22. The length of the pipe can be measured by the annular scale lines marked on the second clamping member 20, so as to facilitate the control of the length of the pipe after sawing.

[0032] Among them, such as Figure 5 As shown, a first sprocket 26 is rotatably connected to the second rotating support rod 23. The first sprocket 26 is fixedly connected to the third clamping member 24 through a fixed connecting block 27. An annular chain 28 is sleeved on the first sprocket 26, and a second sprocket 29 is sleeved inside the annular chain 28. The center of the second sprocket 29 is rotatably connected to the third rotating support rod 30, which is fixedly connected to the working platform 1. A sleeve 31 is sleeved on the third rotating support rod 30, and the second sprocket 29 is supported above the sleeve 31. A drive disc 32 is bolted to the second sprocket 29, and a handle 33 is provided on one side of the drive disc 32. After each sawing is completed, the handle 33 can be cranked, which drives the second sprocket 29, the annular chain 28, and the first sprocket 26 to rotate synchronously through the drive disc 32, thereby driving the third clamping member 24 to rotate, thus clamping the pipe in the gap between the two sets of third clamping members 24, and preventing the pipe from sliding through the third anti-slip rubber collar 25.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In this invention, firstly, the pipe is clamped and fixed by the first clamping mechanism and the second clamping mechanism. The pipe is clamped in the gap between the first clamping member 13 and the second clamping member 20, and in the gap between the two sets of third clamping members 24. Then, the handle 33 is cranked, which drives the second sprocket 29, the annular chain 28 and the first sprocket 26 to rotate synchronously through the drive disc 32, thereby driving the third clamping members 24 to rotate. The pipe is clamped and fed by the two sets of third clamping members 24. At the same time, the second clamping member 20 also rotates, cooperating with the markings on the second clamping member 20. The annular scale marks are used to measure the delivery length of the pipe. During this process, pressure is applied to the annular boss 18 by the pressure spring 19 to increase the clamping force of the first clamping member 13 and the second clamping member 20 on the pipe, and to prevent the pipe from sliding relative to the contact surface of the second anti-slip rubber collar 21, so as to improve the measurement accuracy of the pipe delivery length. Then, the electric telescopic rod 2 extends, the rotating motor 10 starts, and drives the rotating rod 5 and the saw blade 6 to rotate at high speed through the second pulley 9, the annular belt 8 and the first pulley 7, and cuts the pipe through the saw blade 6.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
