Description

Technical Field

[0001] This invention belongs to the field of pipe processing technology, and is particularly related to a corrugated pipe end peeling and cutting device. Background Technology

[0002] Corrugated pipes, as flexible pressure-resistant pipe fittings, are widely used in gas transmission, chemical industry, instrumentation, power generation, and other fields. In practical applications, the protective layer on the outer surface of the corrugated pipe usually needs to be peeled off to facilitate subsequent assembly and connection with fittings. With the large-scale application of corrugated pipe products, the processing efficiency of this end peeling process affects overall production capacity.

[0003] Currently, the peeling of corrugated pipe ends mainly relies on manual peeling using blades or cutting machines. This process is cumbersome, inefficient, and it's difficult to guarantee consistent peeling dimensions. While some automated peeling equipment has emerged in recent years to address these issues, most follow a single-pipe cutting process. When corrugated pipe production is large, this sequential cutting and peeling method is inefficient and cannot meet the demands of large-scale production for increased capacity. Therefore, improvements are necessary. Summary of the Invention

[0004] To address the aforementioned deficiencies in the prior art, this application provides a corrugated pipe end peeling and cutting device that can simultaneously peel and cut multiple corrugated pipes, thereby effectively improving processing efficiency.

[0005] To achieve the above objectives, the present invention employs the following techniques: A corrugated pipe end peeling and cutting device, comprising: Multiple pairs of cutting blades are arranged vertically in an array above a base along a first horizontal direction. Each cutting blade has a cutting edge on one side. The cutting edges of each pair of cutting blades are set inward and the upper part of the cutting edges are inclined outward to accommodate the bellows. Multiple rotating columns are respectively located between multiple pairs of cutting blades, with their axes perpendicular to the cutting blades. All rotating columns are rotatably connected to a mounting plate that moves vertically. The diameter of the rotating columns matches the inner diameter of the corrugated pipe to be peeled. The slide plate is slidably connected to a first mounting frame along a first horizontal direction. The first mounting frame is connected to the telescopic end of a lifting mechanism. The lifting mechanism is fixed in an inverted U-shaped frame. The slide plate is driven to move by a pushing mechanism. When the first mounting frame descends a preset distance and a corrugated tube is sleeved on the rotating column, the bottom of the slide plate abuts against the corrugated tube, and the outer skin of the corrugated tube is cut by the cutting edges of a pair of corresponding cutting blades.

[0006] Furthermore, the first mounting frame is rectangular, with its two ends located outside the two ends of the mounting plate, and the bottom of its two ends protruding from the bottom of its sides. The slide plate is slidably connected to the two ends of the first mounting frame, and the bottom of the slide plate protrudes from the bottom of the two sides of the first mounting frame.

[0007] Furthermore, a second mounting frame is connected to the inner side of the mounting plate via a connecting block. The cutting blade is located between the second mounting frame and the mounting plate. Multiple fixing strips are arranged in an array along the length direction inside the second mounting frame. Each fixing strip is equipped with a vertical first guide post. The bottom of the first guide post is connected to the base. A spring is fitted around each first guide post. The two ends of the spring are connected to the top of the base and the bottom of the corresponding fixing strip, respectively. When the spring is in its natural state, the distance between the rotating post and the upper part of the cutting edge of the cutting blade on both sides is greater than the thickness of the corrugated pipe body.

[0008] Furthermore, a pair of rotating rollers is provided between adjacent fixed strips, and both ends of the rotating rollers are rotatably connected to the two sides inside the second mounting frame. Multiple pairs of rotating rollers are respectively located directly below multiple rotating columns to support the corrugated pipe sleeved on the rotating columns.

[0009] Furthermore, both ends of the second mounting frame are slidably connected to vertical second guide posts. The top of a pair of second guide posts is connected to the bottom of the horizontal section of a pair of inverted L-shaped fixing plates on the base, and the bottom of a pair of second guide posts is connected to the top of the base.

[0010] Furthermore, a long, narrow mounting base is provided above the base, with a mounting groove on the top of the mounting base, where multiple pairs of cutting blades are installed.

[0011] Furthermore, a groove is provided on the top of the base, with its length direction parallel to the axis of the rotating column. A slider is slidably connected in the groove. The slider is connected to the bottom of the mounting base. A lead screw is threaded onto the slider. One end of the lead screw passes through one side of the base and is connected to a handwheel. The other end of the lead screw is rotatably connected to the wall at one end of the groove.

[0012] The beneficial effects of this invention are as follows: 1. Multiple corrugated pipes can be stripped simultaneously with one machine, which can improve processing efficiency and effectively reduce the space occupied by the equipment and the number of units purchased under the same production capacity requirements; 2. When the corrugated pipe is pressed down by the slide plate and the cutting is completed, the spring will be in a compressed state. After the lifting mechanism is reset, the spring can automatically push the second mounting frame and the corrugated pipe above it to move upward and get away from the cutting blade, which makes it convenient for workers to pick up and put down the corrugated pipe when loading and unloading. 3. By turning the screw with the handwheel, the slider and mounting base can be moved along the length of the groove, adjusting the distance between the cutting blade and the inner side of the mounting plate, thereby adjusting the cutting length of the corrugated pipe outer skin.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0022] This application provides a corrugated pipe end peeling and cutting device, such as... Figures 1-5 As shown, it includes a cutting blade 1, a rotating column 3, a sliding plate 4, a lifting mechanism 6, etc.

[0023] Specifically, there are multiple pairs of cutting blades 1, arranged vertically in an array above a base 2 along a first horizontal direction, which can be set parallel to the length direction of the base 2. Each cutting blade 1 has a cutting edge on one side, with the cutting edges of each pair of cutting blades 1 facing inward and the upper part of the cutting edges inclined outward to accommodate the corrugated pipe. Specifically, the distance between each pair of cutting blades 1 is smaller than the diameter of the corrugated pipe to be peeled, so that both sides of the corrugated pipe can simultaneously abut the upper part of the cutting edge of a pair of cutting blades 1 to achieve the cutting of the outer layer of the corrugated pipe. There are multiple rotating columns 3, the same number as the number of pairs of cutting blades 1, and they are respectively arranged between the multiple pairs of cutting blades 1. The axis of the rotating columns 3 is perpendicular to the cutting blades 1, and the multiple rotating columns 3 are rotatably connected to a mounting plate that moves in the vertical direction. The diameter of the rotating columns 3 matches the inner diameter of the corrugated pipe to be peeled.

[0024] For details, please refer to Figure 5 The slide plate 4 is slidably connected to a first mounting frame 5 along a first horizontal direction. The first mounting frame 5 is connected to the telescopic end of the lifting mechanism 6. The lifting mechanism 6 can be a pair of synchronously telescopic electric push rods or cylinders, fixedly installed in an inverted U-shaped frame 8. The slide plate 4 is driven to move by a pushing mechanism. When the first mounting frame 5 descends a preset distance and a corrugated tube is sleeved on the rotating column 3, the bottom of the slide plate 4 abuts against the corrugated tube, and the corrugated tube moves downward until its peripheral outer skin is cut by the cutting edges of the corresponding pair of cutting blades 1. More specifically, a rubber sheet 404 is laid on the bottom of the slide plate 4, which serves to increase the friction between the slide plate 4 and the corrugated tube, and to provide a certain degree of cushioning when the corrugated tube is pressed down, so as to avoid applying excessive pressure to the cutting blades 1 below.

[0025] For details, please refer to Figure 3 The first mounting frame 5 is rectangular, with its two ends located outside the two ends of the mounting plate, and the bottom of its two ends protruding from the bottom of its sides. The slide plate 4 is slidably connected to the two ends of the first mounting frame 5, and the bottom of the slide plate 4 protrudes from the bottom of the two sides of the first mounting frame 5. In this way, the slide plate 4 is slidably connected to the first mounting frame 5, and the bottom of the slide plate 4 can contact the corrugated pipe below when the first mounting frame 5 moves downward.

[0026] In actual use, first push the mounting plate upward to move the multiple rotating columns 3 to disengage from the cutting blade 1. Then, place the ends of the corrugated pipes to be peeled onto the multiple rotating columns 3. Then lower the mounting plate. At this time, the corrugated pipes will descend due to their own weight until they abut against the cutting edge of the cutting blade 1 below. Then, control the lifting mechanism 6 to move the first mounting frame 5 downward by a preset distance so that the bottom of the sliding plate 4 abuts against the corrugated pipe and presses the corrugated pipe down until its peripheral outer skin is cut by the cutting edge of the corresponding pair of cutting blades 1. Then, control the pushing mechanism to move the sliding plate 4. The sliding plate 4 can then drive the corrugated pipe to rotate through friction. The sliding distance of the sliding plate 4 can be set to be greater than the circumference of the corrugated pipe so that it can drive the corrugated pipe to rotate at least one revolution to cut the outer skin at the end of the corrugated pipe. After the cutting is completed, control the lifting mechanism 6 to reset the first mounting frame 5. Then, lift the mounting plate and take out the corrugated pipe.

[0027] For details, please refer to Figure 3 The driving mechanism includes a rack 401, a gear 403, and a drive motor 402. The rack 401 is located on top of the slide plate 4, and the gear 403 meshes with the rack 401. The output shaft of the drive motor 402 is connected to the gear 403, and the drive motor 402 is fixed to one side of the first mounting frame 5. When the slide plate 4 needs to move, the drive motor 402 is controlled to drive the gear 403 to rotate. The gear 403 can then drive the rack 401 and the slide plate 4 to move. Because the gear 403 and rack 401 are located above the slide plate 4, when the slide plate 4 presses down on the bellows, the gear 403 and rack 401 can provide support to the top of the slide plate 4, improving the pressing effect on the bellows.

[0028] Preferred options, please refer to Figure 4 , Figure 5 A second mounting frame 7 is connected to the inner side of the mounting plate via a connecting block 706. The cutting blade 1 is located between the second mounting frame 7 and the mounting plate. Multiple fixing strips 702 are arranged in an array along the length of the second mounting frame 7. Each fixing strip 702 has a vertical first guide post 703 threaded through it. The bottom of the first guide post 703 is connected to the base 2. A spring 707 is fitted around each first guide post 703. The two ends of the spring 707 are connected to the top of the base 2 and the bottom of the corresponding fixing strip 702, respectively. When the spring 707 is in its natural state, the distance between the rotating post 3 and the upper part of the cutting edge of the cutting blade 1 on both sides is greater than the thickness of the corrugated pipe body, causing the outer skin of the corrugated pipe to detach from the cutting blade 1. When the corrugated pipe is pressed down by the sliding plate 4 and the cutting is completed, the spring 707 will be in a compressed state. After the lifting mechanism 6 resets, the spring 707 can automatically push the second mounting frame 7 and the corrugated pipe above it upwards to detach from the cutting blade 1, facilitating the handling of the corrugated pipe during loading and unloading.

[0029] For details, please refer to Figure 4The second mounting frame 7 has vertical second guide posts 704 slidably connected to both ends. The top of the pair of second guide posts 704 is connected to the bottom of the horizontal section of the pair of inverted L-shaped fixing plates 705 on the base 2, and the bottom of the pair of second guide posts 704 is connected to the top of the base 2, which further improves the stability of the second mounting frame 7 moving up and down.

[0030] Preferred options, please refer to Figure 4 Each pair of rotating rollers 701 is provided between adjacent fixed strips 702. Both ends of the rotating rollers 701 are rotatably connected to the two sides inside the second mounting frame 7. Multiple pairs of rotating rollers 701 are respectively located directly below multiple rotating columns 3 to support the corrugated pipe sleeved on the rotating column 3 and provide support for the rear section of the corrugated pipe. When the corrugated pipe rotates under the friction of the slide plate 4, the rotating rollers 701 can also rotate due to friction, thereby reducing the wear on the periphery of the corrugated pipe.

[0031] For details, please refer to Figure 6 , Figure 7 A long, narrow mounting base 9 is provided above the base 2. The top of the mounting base 9 has a mounting groove 903. Multiple pairs of cutting blades 1 are installed in the mounting groove 903. More specifically, the cutting blades 1 and the mounting base 9 are connected by screws and nuts, so that the cutting blades 1 can be disassembled and replaced.

[0032] Preferred options, please refer to Figure 6 , Figure 7 The top of the base 2 has a groove 201 whose length direction is parallel to the axis of the rotating column 3. A slider 904 is slidably connected in the groove 201. The slider 904 is connected to the bottom of the mounting base 9. A lead screw 901 is threaded onto the slider 904. One end of the lead screw 901 extends out of one side of the base 2 and is connected to a handwheel 902. The other end of the lead screw 901 is rotatably connected to the wall of one end of the groove 201. By rotating the lead screw 901 through the handwheel 902, the slider 904 and the mounting base 9 can be moved along the length direction of the groove 201, adjusting the distance between the cutting blade 1 and the inner side of the mounting plate, thereby adjusting the cutting length of the corrugated pipe outer skin.

Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from its scope are all within the protection scope of the present invention.
