Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing technology, and in particular to a cutting device for pipe manufacturing. Background Technology

[0002] Pipe cutting is a crucial step in pipe manufacturing, aiming to cut long pipes into the required lengths and shapes to meet the application needs of various industries. The quality of the cutting directly affects the performance and safety of the pipes.

[0003] In the production of polyethylene pipes, fixed-length cutting is a crucial step. Before each cut, the pipe needs to be measured using measuring tools, which wastes a lot of time and reduces cutting efficiency, thus affecting production efficiency. Therefore, we propose a cutting device for pipe production. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cutting device for pipe production.

[0005] This utility model is achieved using the following technical solution: a cutting device for pipe production, comprising a fixed frame, several inclined rollers rotatably connected to both sides of the inner wall of the fixed frame, a pipe being provided at the upper end of the rollers, a conveying component being provided at the right end of the fixed frame, an clearance groove being provided on the inner wall of the fixed frame, a support frame being fixedly connected to the top of the fixed frame, a hydraulic rod being fixedly connected to the top of the support frame, the output end of the hydraulic rod passing through the support frame and being fixedly connected to a fixed plate, a cutting blade being fixedly connected to the bottom of the fixed plate, an extension plate being fixedly connected to the left end of the support frame, a positioning cylinder being fixedly connected to the top of the extension plate, and the output end of the positioning cylinder passing through the extension plate and being fixedly connected to the positioning plate;

[0006] The conveying assembly includes a mounting frame, a mounting plate fixedly connected to the bottom of the inner wall of the mounting frame, a lead screw rotatably connected to the inner wall of the mounting plate, a sliding seat threadedly connected to the surface of the lead screw, a limit rod slidably connected to the inner wall of the sliding seat, two symmetrically arranged upright plates fixedly connected to the top of the sliding seat, a clamping cylinder fixedly connected to the end of each upright plate that is close to each other, a clamping plate fixedly connected to the output end of the clamping cylinder, and a motor fixedly connected to the right end of the mounting plate.

[0007] The above technical solution connects the motor to an external power source to provide the necessary power for operation. An external PLC controller sets the motor's operating program. During operation, the output end of the clamping cylinder pushes the clamping plate to move, clamping and fixing the pipe. Then, the motor is started, driving the lead screw to rotate. Because the sliding seat is threadedly connected to the lead screw, the sliding seat moves to the left, causing the pipe to move to the left as well. When the pipe reaches the set distance, the output end of the clamping cylinder retracts, releasing the pipe from its fixation. The motor then rotates in the opposite direction, causing the lead screw to rotate in the opposite direction, moving the sliding seat to the right back to its original position. Repeating these steps allows for feeding the same length of material each time, reducing measurement time and improving production efficiency. Rollers also reduce friction on the pipe.

[0008] As a further improvement to the above solution, the left end of the mounting bracket is fixedly connected to the right end of the fixing bracket, and both ends of the limiting rod are fixedly connected to the inner wall of the mounting plate.

[0009] The above technical solution uses a limiting rod to limit the sliding seat, ensuring the stability of the sliding seat during movement and preventing deviation.

[0010] As a further improvement to the above solution, two limiting rods are provided, and the two limiting rods are symmetrically distributed with the mounting plate as the center.

[0011] The above technical solution uses two limiting rods to support the sliding seat, ensuring its load-bearing capacity and improving structural stability.

[0012] As a further improvement to the above solution, the output end of the motor is fixedly connected to the left end of the lead screw.

[0013] As a further improvement to the above solution, the inner wall of the support frame is provided with a limiting groove, and the two ends of the fixing plate are slidably connected to the inner wall of the limiting groove.

[0014] The above technical solution uses a limiting groove to limit the position of the fixed plate, preventing the cutting blade from shifting during movement and thus ensuring the cutting quality.

[0015] As a further improvement to the above solution, the inner wall of the positioning plate is provided with an arc-shaped groove.

[0016] The above technical solution involves contacting and squeezing the pipe through the arc-shaped groove on the inner wall of the positioning plate, making it suitable for pipes of different diameters.

[0017] As a further improvement to the above solution, a collection box is provided at the left end of the fixed frame, and casters are fixedly connected to the four corners of the bottom of the collection box.

[0018] The above technical solution uses a collection box to collect the cut pipes, and casters to facilitate the movement of the collection box, making it easier to transfer the pipes inside the collection box later, thus improving its practicality.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention utilizes a conveying assembly. Specifically, the output end of a clamping cylinder pushes a clamping plate to move, clamping and fixing the pipe. Then, a motor is started, driving a lead screw to rotate. Because the sliding seat is threadedly connected to the lead screw, the sliding seat moves to the left, causing the pipe to move to the left as well. When the pipe reaches a set distance, the output end of the clamping cylinder retracts, releasing the pipe from its fixation. The motor then rotates in the opposite direction, causing the lead screw to rotate in the opposite direction, moving the sliding seat to the right back to its original position. Repeating these steps allows for feeding the same length of pipe each time, reducing measurement time and improving production efficiency.

[0021] This utility model incorporates a collection box and casters. Specifically, the cut pipes are pushed into the collection box by the subsequent feeding pipes. The collection box collects the cut pipes, and the casters facilitate the transport of the collection box. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5 This embodiment of a pipe cutting device includes a fixed frame 1. Several inclined rollers 2 are rotatably connected to both sides of the inner wall of the fixed frame 1. A pipe 3 is provided at the upper end of the rollers 2. A conveying component 4 is provided at the right end of the fixed frame 1. An avoidance groove 5 is provided on the inner wall of the fixed frame 1. A support frame 6 is fixedly connected to the top of the fixed frame 1. A hydraulic rod 7 is fixedly connected to the top of the support frame 6. The output end of the hydraulic rod 7 passes through the support frame 6 and is fixedly connected to a fixed plate 8. A cutting blade 9 is fixedly connected to the bottom of the fixed plate 8. An extension plate 10 is fixedly connected to the left end of the support frame 6. A positioning cylinder 11 is fixedly connected to the top of the extension plate 10. The output end of the positioning cylinder 11 passes through the extension plate 10 and is fixedly connected to a positioning plate 12.

[0032] The conveying assembly 4 includes a mounting frame 401. A mounting plate 402 is fixedly connected to the bottom inner wall of the mounting frame 401. A lead screw 403 is rotatably connected to the inner wall of the mounting plate 402. A sliding seat 404 is threaded onto the surface of the lead screw 403. A limit rod 405 is slidably connected to the inner wall of the sliding seat 404. Two symmetrically arranged upright plates 406 are fixedly connected to the top of the sliding seat 404. Clamping cylinders 407 are fixedly connected to the ends of the upright plates 406 that are close to each other. A clamping plate 408 is fixedly connected to the output end of the clamping cylinder 407. A motor 409 is fixedly connected to the right end of the mounting plate 402. When conveying material to the pipe 3, the clamping cylinders 407 are activated. The output end of clamping cylinder 407 pushes the clamping plate 408 to move, clamping and fixing the pipe 3. Then, the motor 409 is started, driving the lead screw 403 to rotate. Since the sliding seat 404 is threadedly connected to the lead screw 403, the sliding seat 404 moves to the left, driving the pipe 3 to move to the left. When it moves to the set distance, the output end of clamping cylinder 407 retracts, releasing the fixation of the pipe 3. The motor 409 rotates in the opposite direction, causing the lead screw 403 to rotate in the opposite direction, driving the sliding seat 404 to move to the right back to its original position. Repeating the above steps can achieve feeding of the same length each time, reducing the time wasted on measurement and improving production efficiency.

[0033] The left end of the mounting bracket 401 is fixedly connected to the right end of the fixing bracket 1, and both ends of the limiting rod 405 are fixedly connected to the inner wall of the mounting plate 402.

[0034] There are two limit rods 405, which are symmetrically distributed with the mounting plate 402 as the center.

[0035] The output end of motor 409 is fixedly connected to the left end of lead screw 403.

[0036] The inner wall of the support frame 6 is provided with a limiting groove, and the two ends of the fixing plate 8 are slidably connected to the inner wall of the limiting groove.

[0037] The inner wall of the positioning plate 12 is provided with an arc-shaped groove. When the positioning cylinder 11 is activated, the output end of the positioning cylinder 11 pushes the positioning plate 12 to move downward, thereby fixing the pipe 3 and preventing the pipe 3 from moving during the cutting process.

[0038] A collection box 13 is provided on the left end of the fixed frame 1. Universal wheels 14 are fixedly connected to the four corners of the bottom of the collection box 13. The cut pipe 3 can be collected through the collection box 13, and the universal wheels 14 facilitate the transportation of the collection box 13.

[0039] The implementation principle of a pipe cutting device in this embodiment is as follows: During use, the pipe 3 is placed above the roller 2. When cutting the pipe 3, the positioning cylinder 11 is activated, and its output end pushes the positioning plate 12 downwards, fixing the pipe 3. Then, the hydraulic rod 7 is activated, and its output end pushes the fixing plate 8 downwards, causing the cutting blade 9 to cut the pipe 3. When the pipe 3 needs to be transported, the clamping cylinder 407 is activated, and its output end pushes the clamping plate 408 to move, clamping and fixing the pipe 3. Then, the motor 409 is activated, driving the lead screw 403 to rotate. Since the sliding seat 404 is threadedly connected to the lead screw 403, the sliding seat 404 moves to the left, causing the pipe 3 to move to the left. When it moves to the set distance, the output end of the clamping cylinder 407 retracts, releasing the fixation of the pipe 3. The motor 409 rotates in the opposite direction, causing the lead screw 403 to rotate in the opposite direction, causing the sliding seat 404 to move to the right to its original position. Repeating the above steps can achieve feeding of the same length each time, reducing the time wasted on measurement and improving production efficiency. The cut pipe 3 will be pushed into the collection box 13 by the subsequently fed pipe 3. The collection box 13 can collect the cut pipe 3, and the universal wheels 14 facilitate the transfer of the collection box 13.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
