Description

Technical Field

[0001] The present application relates to the technical field of cutting equipment, and in particular to a cable protection tube cutting device. Background Art

[0002] Currently, the cutting of cable protection conduits (such as PVC, HDPE, and metal pipes) primarily relies on manual, semi-automatic, or fully automatic cutting equipment, but numerous technical bottlenecks remain. Traditional cutting methods (such as saw blade cutting and grinding wheel cutting) are prone to burrs and beveled cuts, which affect the efficiency of cable threading and are difficult to adapt to the cutting requirements of different pipe diameters (Φ50-200mm) and materials. Existing equipment often relies on manual adjustment of fixtures or tools, with a low degree of automation, resulting in unstable cutting accuracy and limited production efficiency.

[0003] In terms of energy consumption and environmental protection, traditional cutting machines often use high-power motors or hydraulic drives, resulting in high energy consumption and noise, which is inconsistent with the trend of green manufacturing. Furthermore, the plastic or metal debris generated during the cutting process can easily fly, polluting the work environment, potentially damaging the equipment, and threatening operational safety. While some high-end equipment incorporates laser or water jet cutting technology, these are costly and require high operator skills, making them difficult to adopt for small and medium-sized enterprises.

[0004] In recent years, some improvements (such as the adaptive fixture in CN114770628A and laser-assisted cutting in JP2020157114A) have attempted to improve precision and efficiency, but problems still exist, such as cumbersome tool changes, insufficient vibration suppression, and incomplete waste recovery. Therefore, there is an urgent need to develop low-cost, high-precision, and intelligent cable protection tube cutting equipment to meet the demand for efficient and environmentally friendly cutting technology in industries such as power and communications.

[0029] like Figure 1 and Figure 2As shown, in one embodiment of the present application, a cable protection tube cutting device is disclosed, including a base 100, to which a cutter disc bracket 110 is fixedly connected, and a cutter disc 111 that can slide in the vertical direction is slidably connected to the cutter disc bracket 110. A crossbeam 112 is slidably connected at a position of the cutter disc bracket 110 corresponding to the cutter disc 111, and the cutter disc 111 is rotatably connected to the middle part of the crossbeam 112. The crossbeam 112 is slidably connected to the cutter disc bracket 110 through a cutter disc slide groove 113 provided opposite to the cutter disc bracket. A vertically arranged threaded screw 114 is provided at positions of the cutter disc bracket 110 corresponding to both ends of the crossbeam 112, and the crossbeam 112 and the threaded screw 114 are both threadedly connected. An auxiliary motor 115 is fixedly connected at a position of the cutter disc bracket 111 corresponding to the bottom end of the threaded screw 114, and the auxiliary motor 115 is used to drive the threaded screw 114 to rotate.

[0030] Through the cooperation of the crossbeam and the threaded screw, the cutter disc 111 can be easily moved up and down in a controlled manner to cut the pipe to be cut on the base.

[0031] In any embodiment of the present application, the cutter disc 111 may be driven by other forms of driving mechanisms such as a cylinder, a hydraulic cylinder, etc., or may be driven by the cooperation of a servo motor with a transmission structure such as a gear or a screw.

[0032] like Figure 1 and Figure 2 As shown, in any embodiment of the present application, a cutterhead motor 116 is fixedly connected to the crossbeam 112 at a position corresponding to the cutterhead 111. The cutterhead motor 116 is used to drive the cutterhead 111 to rotate and perform the cutting operation on the pipe to be cut. Minimizing unnecessary transmission mechanisms in driving the cutterhead 111 can prevent wear and tear of transmission components, reduce the frequency of cutterhead 111 replacement and equipment maintenance, and thus improve operational consistency and stability.

[0033] like Figure 1 and Figure 3 As shown, in any embodiment of the present application, a limiting mechanism 120 is provided at the position on both sides of the cutter disc 111 of the cutter disc support 110, and the limiting mechanism includes a limiting assembly 121 slidably connected to both sides of the cutter disc 111. The limiting assembly includes a limiting block 122 slidably connected to the cutter disc support 110. A limiting support rod 123 is fixedly connected to the cutter disc support 110 at the position corresponding to each limiting block 122, and a limiting support column 124 is slidably connected to the limiting support rod 123 through a slide groove provided in the vertical direction. The limiting block 122 is fixedly connected to the bottom end of the limiting support column 124. A vertically arranged limiting screw 125 is rotatably connected to the position of the cutter disc support 110 corresponding to the limiting support rod 123. The limiting screws are driven to rotate by a limiting motor 126, and the limiting support column 124 is threadedly connected to the limiting screw 125.

[0034] Through the above technical solution, when cutting pipes, the limit block can be driven down to the position to clamp the pipe by the limit motor, and then the cutter disc 111 can be lowered, so that the pipe is stably fixed, the cutting stability is improved, and the chance of burrs is reduced.

[0035] like Figure 3 As shown, the side of the limit block 122 close to the base is slidably connected to a contact block 127, and the contact block is slidably connected to the limit block 122 along the length direction of the central axis of the cutter disc 111. The limit block is provided with a contact groove 128 arranged along the central axis direction of the cutter disc 111, and the contact block 127 is slidably connected in the contact groove 128. A locking assembly 130 is provided at the position of the limit block corresponding to the contact groove to limit or drive the position change of the contact block 127.

[0036] like Figure 3 As shown, in any embodiment of the present application, the locking assembly 130 includes a locking spring 131 whose two ends are fixedly connected to the limit block 122 and the contact block 127 respectively. The locking spring 131 is located in the contact groove 128. When the locking spring 131 is in a natural state, the contact block 127 is located at a position away from the cutter disc 111. The locking assembly 130 also includes a locking piston cylinder 132, which can be a pneumatic cylinder or a hydraulic cylinder. The cylinder body of the locking piston cylinder 132 is fixedly connected to the limit block 122, and the piston rod is arranged along the central axis direction of the cutter disc 111. The piston rod is fixedly connected to the contact block 127. When the piston rod of the locking piston cylinder 132 extends out of the cylinder body, the contact block 127 is located close to the cutter disc 111.

[0037] Through the above-mentioned locking assembly, when in use, the contact block is first pushed to a position close to the cutter disc 111 through the locking piston cylinder, the limit block is lowered to limit the pipe, and the drive of the locking piston cylinder is released. At this time, the contact block can remain stationary with the pipe under the action of the friction force of the pipe and the downward pressure from the limit block, but under the action of the deformation potential energy of the locking spring, a force is applied to the pipe in the direction away from the cutter disc 111. Therefore, when the cutter disc 111 cuts the pipe to a certain notch, the contact block can drive the cut part of the pipe to move in the direction away from the cutter disc 111, thereby avoiding the generation of burrs on the one hand and avoiding additional kinetic energy loss caused by the pipe clamping the cutter disc 111 on the other hand, thereby facilitating the cutter disc 111 to cut or withdraw from the notch position.

[0038] In the prior art, there is usually a related structure for limiting the position of the pipe, but the structure is usually only used to lock or limit the movement of the pipe, which will result in the pipe being stuck too tightly. When the pipe is partially cut and continues to be cut, the cut surface of the pipe will continue to be in close contact and friction with the cutter disc 111, and it is easy to be cut out of burrs by the cutter disc 111 or the blade. An additional burr repair step is required to achieve secondary processing of the pipe cut, which is time-consuming and labor-intensive. At the same time, because there is not enough space for the cutter disc to cut at the middle cut of the pipe due to the thickness of the cutter disc, the cutter disc 111 will consume additional kinetic energy due to friction with the pipe during the descent process, which increases the energy loss of the cutting operation and the wear of the cutter disc 111 or the cutting tool.

[0039] In another embodiment of the present application, the locking assembly 130 can also achieve the above-mentioned function through two relatively arranged piston cylinders. In addition to the locking piston cylinder 132 described in the aforementioned embodiment, the aforementioned locking spring 131 can be replaced by another piston cylinder. When the piston rod of the piston cylinder is extended, the contact block can be pushed away from the cutter disc 111. When the locking piston cylinder unloads the force, the contact block can be pushed to a position away from the cutter disc 111 through the piston cylinder, thereby driving the pipe to separate through the static friction between the contact block and the pipe.

[0040] like Figure 3 As shown, in any embodiment of the present application, the contact block 127 is made of an elastic material, such as rubber. Its elasticity can further increase the friction between it and the pipe, more stably fixing the pipe. The elastic contact block can offset the vibration generated during the cutting process, achieving a more stable cutting effect and further preventing the generation of burrs.

[0041] like Figure 3 As shown, in any embodiment of the present application, a plurality of limit blocks 122 are arranged in an array on the same side of the cutter disc 111. The limit blocks 122 on the same side of the cutter disc 111 are arranged in an array on the same horizontal plane and perpendicular to the central axis of the cutter disc 111. Because the pipe to be cut is cylindrical, a single limit block cannot prevent the pipe from rotating during the cutting process. By using multiple limit blocks arranged in an array, uncontrolled rotation of the pipe can be effectively prevented, thereby improving cutting quality.

[0042] In any embodiment of the present application, multiple stoppers can be arranged in a direction parallel to the surface of the cutter disc 111, or can be arranged in an array on both sides of the cutter disc 111. By lowering the stoppers to different heights, the outer surface of the pipe to be cut can be further adhered to, and a more stable pipe fixation effect can be achieved. The stoppers arranged in an array can also further prevent the pipe from rotating during the cutting process, apply force to the pipe from multiple angles to clamp the pipe, thereby achieving a more stable pipe fixation.

[0043] like Figure 4As shown, in any embodiment of the present application, the top surface of the base 100 is provided with a support structure 140 for supporting the pipe to be cut. The support structure 140 includes at least two support columns 141 arranged along the length of the central axis of the cutter head 111. The two support columns 141 are arranged horizontally and parallel to each other and arranged perpendicular to their own lengths. A cutting space 142 is defined below the support columns 141 corresponding to the position below the cutter head 111, facilitating the cutter head 111 to feed a greater depth.

[0044] When cutting, the pipe to be cut is placed on the support column to support the pipe, improve the stability of the pipe, and thus improve the cutting quality.

[0045] like Figure 4 As shown, in any embodiment of the present application, the support column 141 is slidably connected to the base 100 perpendicular to its own length direction, and a support groove 143 arranged perpendicular to the length direction of the support column 141 is opened at the position of the base corresponding to the support column, and the support column is slidably connected to the support groove 143 through the support base 144.

[0046] Through the sliding connection of the support column, when cutting different pipes, the operator can slide the support column to the appropriate spacing, thereby improving the adaptability of the device to pipes of different sizes.

[0047] like Figure 4 As shown, in any embodiment of the present application, the support column 141 is slidably connected to the support base 144 along its own length. A support spring 145 is provided on the support base 144. One end of the support spring 145 is fixedly connected to the support base 144, and the other end is fixedly connected to the support column 141. When the support spring 145 is in a natural state, the support column 141 is located away from the cutter disc 111. A support piston cylinder 146 is also provided on the support base 144. The cylinder body of the support piston cylinder 146 is fixedly connected to the support base 144, and the piston rod is provided along the length direction of the support column 141 and fixedly connected to the support column 141. When the piston rod of the support piston cylinder extends out of the cylinder body, the support column 141 is located near the cutter disc 111. The support piston cylinder can be a pneumatic cylinder or a hydraulic cylinder.

[0048] Through the cooperation of the support spring and the support piston cylinder, the support column can move synchronously with the aforementioned contact block. Before starting cutting, the support column is moved to a position close to the cutter disc 111 through the support piston cylinder to support the pipe. Then the force of the support piston cylinder is released. When the pipe is cut, the support column will move away from the cutter disc 111 under the drive of the support spring. On the one hand, it can reduce the probability of burrs during the cutting process. On the other hand, it can facilitate the operator to separate and remove the cut pipe after the cutting is completed.

[0049] In the prior art, the base typically only serves to secure the pipe. This results in various pipe securing devices, including those provided on the base, constantly squeezing the pipe cutout into close contact with the cutter due to the thickness of the cutter disc 111 or cutting tool, generating significant friction during the cutting process. This not only easily damages the cutter, but also consumes additional kinetic energy during cutting, increasing energy consumption and reducing operational efficiency. The above-mentioned technical solution of the present application utilizes the deformation potential energy stored in the spring to naturally drive the pipe to give way to the cutter disc 111 after the cutter disc 111 has advanced to a certain extent. This, in conjunction with the aforementioned contact block, further improves the cutting efficiency of the cutting device.

[0050] When the pipe is completely cut, the contact block above the pipe pulls the pipe away from the cutter head 111, and the support block below the pipe also pulls the pipe away from the cutter head 111. The pipe can naturally break and move a short distance away from the cutter head 111. This not only makes it easier for the operator to remove the pipe, but also prevents the operator from reaching directly under or near the cutter head 111 to move the pipe during the removal process, which may cause injury, thereby improving the safety of the cutting operation. The technical solutions in the existing technology usually focus more on the fixed stability of the pipe and less on the safety of the operator during removal.

[0051] like Figure 4 As shown, in any embodiment of the present application, the outer layer of the support column is provided with a fixing layer made of an elastic material such as rubber. The fixing layer provides more stable support for the pipe. At the same time, the elastic fixing layer can offset the vibration generated during the cutting process, achieving a more stable cutting effect and further preventing the generation of burrs.

[0052] In the existing technology, no matter whether a rotary tool or a reciprocating tool is used, it is inevitable that the pipe will vibrate due to the movement of the tool. This vibration is very small and difficult to be offset by the motorized device. However, if left unchecked, it will easily cause burrs or even uneven cuts at the pipe cuts. By making a fixed layer with elastic material, the elastic material can deform appropriately during the vibration process, which has a better offsetting effect on the vibration, thereby reducing the probability of burrs and burrs during the cutting process.

[0053] Any embodiment of the present application, through the use of locking springs and support springs, can utilize a spring-driven automatic separation mechanism to reduce the continuous contact between the cutter disc 111 and the pipe, reduce the motor load, and thus reduce the overall energy consumption of the cutting operation, while avoiding the safety risks of manual intervention in the separation step, and at the same time improving the efficiency and safety of the cutting operation.

[0054] By using the technical solution of the cable protection tube cutting device in any embodiment of the present application, when in use, first adjust the spacing between the support columns to a suitable position, and push the support columns and the contact block to a position close to the cutter disc 111 through the support piston cylinder and the locking piston cylinder. After the pipe is placed on the support column, slide the limit block downward, use the contact block to support and fix the pipe, and then control the cutter disc 111 to cut the pipe. During the cutting process, release the force of the support piston cylinder and the locking piston cylinder, and let the contact block and the support column pull the pipe on both sides of the cutter disc 111 away from the cutter disc 111 as the cutting progresses, thereby avoiding burrs and repeated cutting. After the cutting is completed, the two sections of the pipe are naturally separated, making it convenient for the operator to remove the pipe.

[0055] The specific method and steps for using the cutting device described in any embodiment of the present application are as follows:

[0056] Step 1: Equipment preparation and pipe positioning.

[0057] First, the spacing between the support columns is adjusted to accommodate the pipe to be cut. Based on the diameter of the pipe to be cut, the operator slides the support columns 141 of the support mechanism 140 along the support slots 143 of the base 100, adjusting the spacing between the two support columns to be slightly smaller than the pipe diameter. The support columns 141 are adjusted by sliding the support base 144, and the position of the support columns is fixed by the operator limiting the support base 144 or adding a mechanism to limit the support base's position.

[0058] Principle: The sliding connection structure of the support column 141 cooperates with the support groove 143 to ensure that pipes of different sizes can be stably placed on the support column. The elastic fixing layer (such as rubber) on the surface of the support column prevents the pipe from rolling through friction.

[0059] Secondly, the support column and contact block are positioned to ensure that they can play the expected role during subsequent use.

[0060] First, the support piston cylinder 146 is activated, driving the support column 141 toward the cutterhead 111 to a preset position. Simultaneously, the locking piston cylinder 132 is activated, pushing the contact block 127 closer to the cutterhead 111. This movement ensures that the support column 141 and contact block 127 exert sufficient tension against the corresponding spring travel, ensuring a significant pulling and rebound effect as the pipe is cut. This hydraulic / pneumatic actuation allows for rapid positioning, providing initial support and a clamping reference for subsequent cutting.

[0061] Step 2: Fix and limit the pipe.

[0062] First, place the pipe and lower the stopper.

[0063] The pipe is placed on support column 141, and the limit motor 126 is activated to rotate the limit screw 125, which drives the limit support column 124 downward along the slide groove of the limit support rod 123, causing the contact block 127 of the limit block 122 to press against the pipe surface. Because each side of the cutter disc 111 has multiple sets of limit blocks 122, even though the pipe is cylindrical, the multiple sets of limit blocks 122 can be lowered to different heights by their corresponding limit motors 126 to adapt to the outer contour of the pipe. Furthermore, multiple sets of limit blocks 122 are arranged in an array on the same side of the cutter disc 111 to form a multi-point clamping, which can stably clamp a variety of special-shaped pipes. The elastic material (such as rubber) of the contact block 127 increases friction and prevents the pipe from rotating and deviating.

[0064] Secondly, when the limit block descends to a suitable position, the locking assembly is dynamically fixed.

[0065] When the locking piston cylinder 132 retracts or releases force (i.e., the piston rod is no longer under force and is in a free-moving state), the contact block 127, under the action of the locking spring 131, generates elastic potential energy in a direction away from the cutter head 111, but is temporarily held stationary by the friction of the pipe. This dynamic balance between elastic deformation and friction provides a preload force for pipe separation during the middle and later stages of cutting.

[0066] Step 3: Cutter cutting and dynamic adjustment of pipes.

[0067] First, the cutter head is fed for cutting.

[0068] Auxiliary motor 115 is activated to rotate threaded screw 114, which in turn drives crossbeam 112 downward along cutterhead slot 113. Cutterhead motor 116 then drives cutterhead 111 to rotate at high speed to cut the pipe. The precise drive of threaded screw 114 ensures stable vertical feed of the cutterhead and reduces cutting vibration. In other embodiments of the present application, a servo motor can also be used to provide a power source for precise cutterhead feed.

[0069] During the cutting process, if the pipe being cut is of small size (the pipe diameter is smaller than the cutter disc radius), the cutting can be completed directly. If the pipe diameter being cut is larger than the cutter disc radius, the operator needs to manually rotate the pipe during the cutting process to achieve complete cutting. At this time, because the above-mentioned contact block 127 and the support block 141 will pull the pipe away from the cutter disc under the action of their corresponding springs, it is also more convenient for the operator to rotate or displace the pipe, so that the cut edge can be opened, which is convenient for finding the cutting position later.

[0070] After the cutting is completed, the support column and the contact block will retract synchronously to separate the two cut sections of the pipe.

[0071] During the cutting process, support piston cylinder 146 and locking piston cylinder 132 gradually release pressure, allowing support column 141 to move away from the cutter disc under the action of support spring 145. Contact block 127, driven by locking spring 131, pulls the cut section of tubing apart. This spring-driven dynamic retraction reduces friction between the cutter disc and the tubing, preventing burrs and automatically separating the cut sections.

[0072] In other embodiments of the present application, the support block and the contact block can also be used to separate the pipe by other means such as a linear motor, a threaded screw, etc. If these methods are used, it is necessary to start the above-mentioned drive structure through the operation of the operator when the cutting is completed to drive the contact block and the support block to move away from the cutter disc 111.

[0073] Step 4: Cutting completion and resetting.

[0074] After the cutting is completed, the operator needs to reset the equipment and remove the pipe.

[0075] After cutting is completed, the auxiliary motor 115 reverses and raises the cutter disc 111 to its initial position; the limit motor 126 drives the limit block 122 to rise and reset, and the operator removes the cut pipe. In any embodiment of the present application, the automatic reset mechanism can shorten the operation cycle and improve the efficiency of continuous cutting.

[0076] Through the above-mentioned operating steps, combined with programming, automatic control and other solutions, semi-automatic pipe fixing, cutting, resetting and other operations can be realized, further improving the efficiency of the cutting device and reducing manpower loss.
