Description

Technical Field

[0001] This invention relates to the field of corrugated pipe processing equipment technology, specifically to a grooving and cutting machine for cable protection corrugated pipes. It can realize integrated operation of corrugated pipe limiting, feeding, half cutting, full cutting and fixed length cutting, and is suitable for batch processing of cable protection corrugated pipes in mechanical equipment and other fields. Background Technology

[0002] The corrugated pipe body possesses excellent flexibility, corrosion resistance, and support and protection properties. Reinforcing rings are spaced around the perimeter of the pipe body for added support. It is used in the field of cable protection for mechanical equipment, effectively preventing cables from being subjected to external wear, corrosion, and interference. Before use, the corrugated pipe requires specific processing. This includes not only cutting to a fixed length but also creating a full-cut opening in the pipe body to insert the cable, and a partial-cut opening to facilitate the unfolding of the full-cut opening and rapid cable insertion.

[0003] Currently, existing corrugated pipe processing equipment suffers from the following technical defects: First, the processing flow is fragmented, with functions such as limiting, transmission, grooving, and cutting mostly completed by independent equipment. This requires manual handling of the corrugated pipe, resulting in low processing efficiency. Furthermore, multiple positioning operations can easily lead to deviations in processing accuracy, affecting the processing effect. Second, the limiting mechanism of existing equipment has poor adaptability, making it difficult to be compatible with corrugated pipes of different diameters. Moreover, the limiting stability is insufficient, causing the corrugated pipe to easily shift or shake during processing, resulting in uneven cuts and deviations in opening positions.

[0004] In view of the above-mentioned shortcomings of the existing technology, there is an urgent need for a corrugated pipe grooving and cutting machine that integrates limiting, transmission, full cutting, half cutting and cutting functions, has stable positioning, strong adaptability, convenient operation and high safety, so as to meet the batch processing needs of corrugated pipes for cable protection.

Detailed Implementation

[0023] The following detailed description of the specific implementation of the corrugated pipe grooving and cutting machine, in conjunction with the overall structural design of the present invention, is provided. This embodiment is only used to explain the present invention and is not intended to limit the scope of protection of the present invention.

[0024] The corrugated pipe grooving and cutting machine of the present invention has all the connection relationships and operating principles of its mechanisms and components consistent with the claims. The core of the machine is to realize the integrated operation of corrugated pipe from material pressure and limiting, uniform speed feeding, full and half cutting processing to fixed length cutting. It is suitable for processing cable protection corrugated pipes of different diameters. The following are the specific structural details and working process description.

[0025] As shown in Figures 3 and 4, the core assembly base of this corrugated pipe grooving and cutting machine is the machine base 6. The machine base 6 is made of high-strength steel structure and is rectangular in shape. Anti-slip pads can be added to the bottom to ensure the stability of the equipment during operation. The top is fixed with the frame 5 by bolt group. The frame 5 extends along the length of the machine base 6 and provides rigid installation support for all functional mechanisms.

[0026] The protective cover 7 is a stainless steel protective shell, fixed to the machine base 6 with bolts. The protective cover 7 is located on the outside of the frame 5, covering the areas of moving parts such as the servo transmission mechanism 2, the full and half cutting mechanism 3, and the cutting mechanism 4. A transparent observation window is opened on the protective cover 7, which allows the operator to check the processing status in real time. At the same time, it effectively prevents foreign objects from entering the equipment during processing and avoids safety hazards to the operator caused by moving parts. The touch screen 8 is an industrial touch interactive screen, which is embedded in the side of the protective cover 7 and electrically connected to the internal electrical control module of the equipment. It can realize the input of processing parameters, the start and stop of the equipment and the real-time display of the running status, making the operation convenient.

[0027] As shown in Figures 1 and 2, the pressing and limiting mechanism 1, the first set of servo transmission mechanism 2, the full and half cutting mechanism 3, the second set of servo transmission mechanism 2, and the cutting mechanism 4 are fixedly installed on the frame 5 from left to right along its length. The two sets of servo transmission mechanisms 2 have the same structure and specifications, and provide power for the feeding of the corrugated pipe. The installation spacing of each mechanism is adapted to the process requirements of corrugated pipe processing to ensure the continuous connection of each process.

[0028] The material pressing and limiting mechanism 1 is the initial positioning mechanism of the equipment. It is installed on the leftmost side of the frame 5 and is used to limit the corrugated pipe entering the equipment in the vertical and horizontal directions. At the same time, the material feeding roller 105 lifts the corrugated pipe to prevent the corrugated pipe from sagging due to its own weight and causing positioning deviation. It includes a liftable upper limit pressure roller assembly, an adjustable left and right limit guide roller assembly, and several material feeding rollers 105. The material feeding rollers 105 are evenly distributed along the length of the frame 5 and are all rotatably mounted on the frame 5 through bearings. The corrugated pipe is conveyed by adhering to the upper surface of the material feeding roller 105.

[0029] The upper limit pressure roller assembly includes a first limit cylinder 101 fixedly installed on the top of the frame 5. The piston rod end of the first limit cylinder 101 is fixedly connected to the first pressure plate 107. The two sides of the first pressure plate 107 are slidably engaged with the first linear guide rail 103 on the frame 5. The first linear guide rail 103 is vertically arranged to ensure the lifting and lowering guidance accuracy of the first pressure plate 107. Several pressure rollers 102 are rotatably mounted on the bottom of the first pressure plate 107 through bearings. The pressure rollers 102 correspond vertically to the material feed roller 105 below. When the piston rod of the first limit cylinder 101 extends or retracts, it can drive the first pressure plate 107 to move downward or upward along the first linear guide rail 103, thereby realizing the pressing or loosening of the pressure rollers 102 and the upper surface of the corrugated pipe, adapting to the upper and lower limit requirements of corrugated pipes of different diameters.

[0030] Left and right limiting guide roller assembly: Includes a screw drive device 106 rotatably connected to the frame 5 via bearings. The screw drive device 106 is a positive and negative thread screw structure, with its two ends connected to two left and right opposing limiting guide rollers 104 via screw drive. The limiting guide rollers 104 are vertically rotatably mounted on a sliding plate. When the operator rotates the adjusting handwheel of the screw drive device 106, the rotation of the positive and negative thread screw can drive the sliding plate and the two limiting guide rollers 104 mounted on the sliding plate to move closer or further apart along the length of the screw drive device 106, thereby achieving left and right clamping or loosening of corrugated pipes of different diameters, ensuring that the center position of the corrugated pipe remains unchanged during transportation, and avoiding lateral deviation.

[0031] The servo transmission mechanism 2 consists of two sets, located between the pressing and limiting mechanism 1 and the full and half cutting mechanism 3, and between the full and half cutting mechanism 3 and the cutting mechanism 4, respectively. It provides uniform and stable driving force for the conveying of the corrugated pipe, ensuring processing accuracy. The two sets of mechanisms have completely identical structures, both including a liftable upper transmission roller assembly and a lower transmission roller assembly.

[0032] The upper drive roller assembly includes a second limiting cylinder 201 fixedly mounted on the top of the frame 5. The piston rod end of the second limiting cylinder 201 is fixedly connected to the second pressure plate 205. The second pressure plate 205 is slidably engaged with the second linear guide rail 203 on the frame 5. The second linear guide rail 203 is vertically arranged. Several upper drive rollers 202 are rotatably mounted on the bottom of the second pressure plate 205 via bearings. The shaft of at least one upper drive roller 202 is connected to the output shaft of a servo motor fixed on the top of the second pressure plate 205. All upper drive rollers 202 are connected by a synchronous drive belt. The second limiting cylinder 201 can drive the second pressure plate 205 to rise and fall along the second linear guide rail 203, realizing the contact and separation of the upper drive rollers 202 with the upper surface of the corrugated pipe.

[0033] The lower drive roller assembly includes several lower drive rollers 204 rotatably mounted on the frame 5 via bearings. The lower drive rollers 204 correspond vertically to the upper drive rollers 202 above. The shaft of at least one lower drive roller 204 is connected to the output shaft of a servo motor fixed at the bottom of the frame 5. All lower drive rollers 204 are connected by a synchronous drive belt.

[0034] When the bellows enters between the upper and lower drive rollers, the second limit cylinder 201 drives the upper drive roller 202 to descend, cooperating with the lower drive roller 204 to clamp the bellows. At this time, the upper and lower servo motors start synchronously, driving the upper drive roller 202 and the lower drive roller 204 to rotate synchronously. Through friction, the bellows is driven to feed at a constant speed from left to right along the frame 5. The feed speed can be adjusted through the touch screen 8 to adapt to different processing requirements.

[0035] The full and half cutting mechanism 3 is installed between the two sets of servo transmission mechanisms 2. It is the core mechanism for grooving the corrugated pipe and realizes the half cutting and full cutting of the corrugated pipe. It includes a liftable half cutting component and a full cutting component. At the same time, in order to ensure the positioning stability of the corrugated pipe during the processing, the mechanism is also equipped with a pressure roller 102, left and right limit guide roller components, and material feeding roller 105 that are completely identical in structure and specifications to the pressure limiting mechanism 1. These components provide auxiliary limiting and lifting for the corrugated pipe, preventing the corrugated pipe from shaking due to the cutting force during processing.

[0036] The semi-cutting assembly includes a third limiting cylinder 301 fixedly mounted on the top of the frame 5. The piston rod end of the third limiting cylinder 301 is fixedly connected to the third pressure plate 305. The third pressure plate 305 is slidably engaged with the third linear guide rail 303 on the frame 5. The third linear guide rail 303 is vertically arranged. The bottom of the third pressure plate 305 is rotatably connected to the semi-cutting blade 302 via a bearing. The rotating shaft of the semi-cutting blade 302 is drively connected to the output shaft of a motor fixed on the top of the third pressure plate 305. The third limiting cylinder 301 can drive the third pressure plate 305 to rise and fall along the third linear guide rail 303, thereby adjusting the descent depth of the semi-cutting blade 302 to achieve semi-cutting processing of the corrugated pipe. The semi-cutting blade 302 only cuts part of the pipe wall of the corrugated pipe, without penetrating it. The semi-cutting depth can be precisely set through the touch screen 8 to adapt to corrugated pipes with different wall thicknesses.

[0037] Full-cut assembly: includes a full-cutting blade 304, which is rotatably connected to the frame 5 via a rotating shaft. The end of the rotating shaft is connected to the output shaft of a servo motor fixed on the frame 5. The servo motor drives the full-cutting blade 304 to rotate at high speed. When the corrugated pipe passes through the full-cutting blade 304 at a constant speed, the corrugated pipe is fully cut open. The full-cutting blade 304 penetrates the wall of the corrugated pipe, providing a channel for subsequent cable installation.

[0038] The cutting mechanism 4 is installed on the far right of the frame 5. It is the fixed-length cutting mechanism of the equipment, which realizes the cutting of the corrugated pipe after processing according to the preset length. It includes a liftable cutting component. At the same time, the mechanism is also equipped with a pressure roller 102, left and right limit guide roller components, and material feeding roller 105 that are completely consistent with the structure and specifications of the pressure limiting mechanism 1. It limits and lifts the corrugated pipe that is about to be cut to ensure the flatness of the cut surface.

[0039] The cutting assembly includes a lift 401 fixedly mounted on the top of the frame 5. The lift 401 is an electric lifting structure, and its output end is fixedly connected to the fourth pressure plate 405. The fourth pressure plate 405 is slidably engaged with the fourth linear guide rail 403 on the frame 5. The fourth linear guide rail 403 is vertically arranged. The extension of the fourth pressure plate 405 is rotatably connected to the circular knife drive shaft 404 through a bearing. A circular knife 402 is fixedly mounted on the circular knife drive shaft 404, and the end of the circular knife drive shaft 404 is connected to the output shaft of a servo motor fixed on the side of the extension of the fourth pressure plate 405 through a drive belt. A servo motor drives the circular blade transmission shaft 404, which in turn drives the circular blade 402 to rotate at high speed. When the corrugated pipe is fed to the preset length, the lifting platform 401 drives the fourth pressure plate 405 to descend along the fourth linear guide rail 403. The high-speed rotating circular blade 402 contacts the corrugated pipe and achieves a fixed-length cut. The cutting length can be precisely set via the touch screen 8 to meet different usage requirements.

[0040] The complete workflow of this invention is as follows: Step 1: The operator inputs processing parameters such as the diameter of the corrugated pipe to be processed, the fixed-length cutting length, the half-cut depth, and the feed speed through the touch screen 8. After receiving the parameters, the electronic control module automatically controls the movement of each limit cylinder and the lifting platform 401, and adjusts the initial positions of the pressure roller 102, the upper transmission roller 202, and the half-cutting blade 302. At the same time, the operator rotates the screw drive device 106 to adjust the spacing of the limit guide rollers 104, thus completing the initial debugging of the equipment.

[0041] Step 2: Place the corrugated pipe to be processed from the left side of the frame 5, and pass it through the material feeding roller 105 of the pressing and limiting mechanism 1, the upper and lower limiting components, the upper and lower transmission rollers of the two sets of servo transmission mechanisms 2, the auxiliary limiting components of the full and half cutting mechanism 3, and finally extend the end to the material feeding roller 105 of the cutting mechanism 4; the electronic control module controls the pressure roller 102 of each mechanism to descend, and the limiting guide roller 104 to clamp, completing the overall positioning of the corrugated pipe.

[0042] Step 3: During operation, the servo motors of the two sets of servo transmission mechanisms 2 start synchronously, driving the corrugated pipe to feed at a constant speed from left to right along the frame 5; when the corrugated pipe passes through the full and half cutting mechanism 3, the full cutter 304 rotates at high speed to achieve full cutting and opening processing, while the half cutter 302 rotates at high speed and descends to the preset depth under the action of the third limit cylinder 301 to achieve half cutting and opening processing of the corrugated pipe. During the processing, each auxiliary limit component continuously positions the corrugated pipe to avoid displacement.

[0043] Step 4: When the feed length of the corrugated pipe reaches the preset cutting length on the touch screen 8, the electronic control module controls the servo transmission mechanism 2 to stop feeding. At the same time, the circular blade 402 of the cutting mechanism 4 rotates at high speed, and the lifting platform 401 drives the circular blade 402 to descend, cutting the corrugated pipe to a fixed length to ensure that the cut surface is flat and burr-free.

[0044] Repeat steps three and four to enable continuous operation of the equipment.

[0045] like Figure 5 As shown, the cross-section of the processed corrugated pipe is half-cut at one end and fully cut at the other end.

[0046] Step 5: After one corrugated pipe material is processed, the electrical control module controls the pressure roller 102 of each mechanism to rise and the limit guide roller 104 to release; at the same time, each cylinder and the lifting mechanism 401 drive each cutting component and transmission component to reset, completing the processing of a single corrugated pipe, and can continue to process the next corrugated pipe, realizing batch operation.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
