Description
Technical Field
[0001] This utility model relates to the field of pipe processing equipment technology, and in particular to a pipe cutting saw with automatic length setting function. Background Technology
[0002] In modern industrial production, precise and efficient cutting of metal or non-metal pipes is an essential process in many manufacturing stages. Traditional pipe cutting operations usually rely on manual measurement and the use of ordinary cutting tools. This method has many obvious shortcomings when dealing with large-scale, standardized production.
[0003] Traditional pipe cutting methods typically involve manual marking and positioning using rulers or simple limiting devices. This method is not only time-consuming and labor-intensive, but also prone to errors due to operator parallax or measurement inconsistencies, leading to increased waste due to size discrepancies and low material utilization. Furthermore, existing cutting equipment often requires changing clamps or making complex adjustments for pipes of different diameters. The clamping process is cumbersome and cannot guarantee that the pipe remains centered during cutting, which can result in skewed or burr-like cuts, affecting the final product quality.
[0004] Therefore, this utility model proposes a pipe cutting saw with automatic length setting function to overcome the shortcomings of the prior art. Utility Model Content
[0005] In view of the problems existing in the pipe cutting saw, such as low accuracy due to manual positioning for cutting length setting, poor batch consistency, poor adaptability of the clamp to different pipe diameters, and unstable clamping, this utility model aims to provide a pipe cutting saw with an automatic length setting function that has been improved in structure and can effectively solve the above problems.
[0006] This utility model provides a pipe cutting saw with automatic length setting function, including: a base, a side plate, a cutting mechanism; as well as a length setting mechanism and a clamping mechanism.
[0007] The base serves as the mounting foundation for the entire device, and the side plate is fixedly connected to the base.

The slide rod is fixed to the side plate, the first slider is slidably connected to the slide rod, the limiting plate is fixedly connected to the first slider, and the second lead screw is rotatably connected to the side plate and threadedly engaged with the first slider. The second lead screw drives the first slider to move along the slide rod by rotating, thereby accurately positioning the position of the limiting plate.
[0010] The clamping mechanism includes a mounting block, a bidirectional threaded rod, a sliding frame, and a clamping plate. The mounting block is fixed to the base, and the bidirectional threaded rod is rotatably connected to the mounting block. The two ends of the bidirectional threaded rod have opposite threads, which respectively thread into two sliding frames. The clamping plate is fixedly connected to the sliding frames. By rotating the bidirectional threaded rod, the sliding frames on both sides can move synchronously towards or away from each other, thereby achieving rapid centering and clamping of the pipe.
[0011] Preferably, a scale plate is fixed on the side plate, and an indicator arrow is fixedly connected to the first slider. The indicator arrow cooperates with the scale on the scale plate to indicate the position of the limiting plate.
[0012] Preferably, the support of the cutting mechanism is also connected to a handle for controlling the rotation of the support.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please refer to Figures 1 to 4 This utility model provides a pipe cutting saw with an automatic length setting function, which aims to solve the problems of low accuracy in setting the pipe cutting length and poor adaptability of the clamping device to pipes of different diameters in the prior art.
[0025] like Figure 1 As shown, the pipe cutting saw includes a base 1 and a side plate 2 fixedly connected to the base 1. The base 1 serves as the mounting base for the entire device, supporting and bearing all components. A cutting mechanism 3 for performing cutting operations is rotatably connected to the base 1. In addition, a fixing mechanism 4 for assisting cutting is provided, as well as a length-setting mechanism 5 for setting the pipe to a fixed length, and a clamping mechanism 6 for firmly clamping the pipe. Both the length-setting mechanism 5 and the clamping mechanism 6 are provided on the base 1.
[0026] like Figure 1 and Figure 2 As shown, the length-fixing mechanism 5 includes a slide rod 501 fixed to the side plate 2. A first slider 504 is slidably connected to the slide rod 501. A limiting plate 505 is fixedly connected to the first slider 504. The limiting plate 505 serves as the cutting positioning end for the tube. A second lead screw 503 is rotatably connected to the side plate 2 to drive the first slider 504 to move along the slide rod 501. The second lead screw 503 and the first slider 504 are driven by a threaded connection. When the second lead screw 503 is rotated, the first slider 504 can be driven to slide precisely on the slide rod 501. To visually display the set cutting length, the position of the limiting plate 505 is changed. A scale plate 506 is also fixed on the side plate 2. An indicator arrow 507 is fixedly connected to the first slider 504. When the first slider 504 is moved, the operator can accurately adjust the position of the limiting plate 505 by matching the scale on the scale plate 506 with the indicator arrow 507, thereby achieving precise setting of the pipe cutting length. The length-fixing mechanism 5 also includes a second fixing plate 502 fixed on the side plate 2. The second lead screw 503 rotates through the second fixing plate 502.
[0027] To solve the above-mentioned technical problems, the pipe cutting saw also includes a clamping mechanism 6, and the clamping mechanism 6 forms a specific structural fit and connection relationship with the base 1, and works in coordination with the fixed length mechanism 5 and the cutting mechanism 3.
[0028] Please refer to Figure 1 and Figure 4 The clamping mechanism 6 includes a mounting block 601 fixedly connected to the base 1. A bidirectional threaded rod 602 is rotatably connected to the mounting block 601. The two ends of the bidirectional threaded rod 602 have opposite threads, adopting a symmetrical thread design to ensure that the components on both sides can move synchronously. The bidirectional threaded rod 602 is threadedly engaged with two sliding frames 603 respectively. A clamping plate 604 for clamping pipes is fixedly connected to the sliding frame 603. The clamping plate 604 has a groove adapted to the shape of the pipe, which can firmly hold circular pipes of different diameters. In order to ensure the smooth movement of the sliding frame 603, a second slider 605 is connected to the bottom of the sliding frame 603. The base 1 has an opening A groove 606 is provided in which the second slider 605 slides. The groove 606 provides precise linear guidance for the second slider 605, ensuring that the clamping plates 604 move towards or away from each other along a fixed path when clamping and releasing the pipe, thereby ensuring that the pipe is always located on the center line of the cutting area. When the bidirectional threaded rod 602 is rotated, due to its symmetrical thread design, the two sliding frames 603 will move towards or away from each other along the groove 606 in sync, thereby causing the clamping plates 604 on both sides to move closer or further away from each other, quickly adapting to the clamping requirements of pipes of different diameters, and ensuring that the pipe will not shift or shake during the cutting process, thereby achieving positional accuracy during cutting.
[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: To control the cutting operation more precisely, a handle 305 is also connected to the bracket 302 of the cutting mechanism 3. The operator can hold the handle 305 to control the angle and position of the bracket 302 on the rotating seat 301, so that the high-speed rotating saw blade 304 moves towards the pipe to carry out the cutting operation.
[0030] In a preferred embodiment, the length-fixing mechanism 5 further includes a second fixing plate 502 fixed to the side plate 2, through which the second lead screw 503 rotates. This structure is used to provide rotational support and axial limit for the second lead screw 503.
[0031] The cutting saw also includes a fixing mechanism 4, which is mounted on the base 1 and is used for the initial positioning and fixing of the pipe to be cut. The fixing mechanism 4 includes a baffle 401 and a first fixing plate 402 fixed on the base 1. The baffle 401 is used to abut against one side of the pipe. A first lead screw 403 is rotatably connected to the first fixing plate 402. A stop block 404 is threaded onto the first lead screw 403. By rotating the first lead screw 403, the stop block 404 abuts against the other side of the pipe, completing the initial positioning and preparing for the clamping of the clamping mechanism 6.
[0032] As a preferred embodiment, the bidirectional threaded rod 602 adopts a symmetrical thread design to ensure that the sliding frames 603 and clamping plates 604 on both sides can move towards each other or away from each other synchronously and at the same speed, thereby ensuring that the pipe is always clamped in the center, improving the stability of clamping and the accuracy of cutting.
[0033] The working principle of this utility model of a pipe cutting saw with automatic length setting function is as follows: When pipes need to be cut to a fixed length, the length-fixing mechanism 5 installed on the side plate 2 is first adjusted. By rotating the second lead screw 503 on the second fixed plate 502, the second lead screw 503 and the first slider 504 are driven by the threaded engagement, so that the first slider 504 slides along the slide rod 501. The limiting plate 505 on the first slider 504 moves accordingly. The operator can accurately adjust the position of the limiting plate 505 by observing the correspondence between the indicator arrow 507 and the scale on the scale plate 506, thereby achieving precise setting of the pipe cutting length.
[0034] The pipe to be cut is then placed on the base 1, with one end against the limiting plate 505. The pipe is initially fixed by the fixing mechanism 4, with one side of the pipe against the baffle 401. By rotating the first screw 403 on the first fixing plate 402, the stop block 404 is made to abut against the other side of the pipe, completing the initial positioning. Then, by rotating the bidirectional threaded rod 602 fixed on the mounting block 601 of the clamping mechanism 6, since the bidirectional threaded rod 602 adopts a symmetrical thread design, when rotating, it will synchronously drive the second slider 605 on the sliding frame 603 on both sides to move towards each other along the sliding groove 606, thereby making the clamping plates 604 on both sides move closer to each other until the clamping plates 604 firmly clamp the pipe from both sides, thus quickly adapting to the clamping requirements of pipes of different diameters and ensuring that the pipe will not shift or shake during the subsequent cutting process.
[0035] After clamping and length setting of the pipe, the motor 303 of the cutting mechanism 3 is started. The motor 303 drives the saw blade 304 to rotate at high speed. The operator holds the handle 305 and controls the angle and position of the bracket 302 on the rotating seat 301, so that the high-speed rotating saw blade 304 moves towards the pipe to perform the cutting operation. After the saw blade 304 finishes cutting the pipe, the bidirectional threaded rod 602 is rotated in the opposite direction, so that the clamping plates 604 on both sides move in the opposite direction and release the pipe. The cut pipe can then be taken out, completing one cycle of pipe length cutting. Through the coordinated action of the length setting mechanism 5 and the clamping mechanism 6, this utility model effectively solves the problems of inaccurate cutting length setting and unstable clamping leading to poor cutting quality in the prior art.
[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
