Description

Technical Field

[0001] This invention relates to the field of stainless steel pipe cutting technology, and in particular to a synchronous cutting machine for stainless steel pipes. Background Technology

[0002] Stainless steel pipe fittings, with their corrosion resistance, high strength, and excellent sealing properties, are widely used in water supply and drainage, chemical industry, machinery manufacturing, HVAC engineering, and many other fields, making them indispensable basic components in industrial production and infrastructure projects. In the processing of stainless steel pipe fittings, precise length cutting is a core preliminary step; the stability, accuracy, and efficiency of the cutting directly determine the subsequent assembly quality and overall production capacity of the pipe fittings.

[0003] Currently, most stainless steel pipe cutting equipment on the market relies on external extrusion clamping mechanisms to fix the pipe and stabilize the cutting process. During operation, external clamps are used to press the outer wall of the pipe from one or both sides to counteract vibrations and displacement deviations caused by the cutting tool, preventing the pipe from shaking or shifting and ensuring the basic completion of the cutting operation. However, this traditional stabilization structure relies solely on external extrusion components, requiring numerous and independently arranged clamping, limiting, and pressing parts. The overall structure is loose, with extremely low integration, occupying a large amount of installation space and resulting in high assembly and maintenance costs. Furthermore, each stabilization mechanism is mostly independently manual or controlled in stages, making it difficult to coordinate with cutting, feeding, and length-cutting processes, thus failing to achieve integrated automated control and resulting in a low overall level of automation.

[0004] Meanwhile, manual control involves many steps and is cumbersome to operate, which not only significantly reduces the efficiency of pipe cutting and processing, but also easily leads to problems such as deviations in cutting accuracy and uneven cuts due to human operation errors, making it difficult to meet the needs of large-scale, high-precision, and automated modern pipe processing and production.

[0005] Therefore, how to achieve integrated clamping stability and automated feeding and length-fixed cutting of stainless steel pipe fittings is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that the existing stainless steel pipe cutting equipment relies on an external extrusion clamping mechanism to fix the pipes. The required clamping components are numerous and independently arranged, resulting in a loose structure and low integration. Each mechanism is mostly independently manual or controlled step by step, making it difficult to link and coordinate with the cutting and feeding processes. The degree of automation is low, and manual operation is prone to cutting accuracy deviations, making it difficult to meet the needs of large-scale and high-precision production.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a synchronous cutting machine for stainless steel pipe fittings, including a main operating platform, on the upper surface of the main operating platform are fixedly installed several horizontally arranged embedded adjustment guide rails, an electrically controlled translation base is movably assembled inside the embedded adjustment guide rails, a combined pipe fitting guide cover is assembled on the upper surface of the electrically controlled translation base, an electrically controlled sliding stabilizing cover is installed on the combined pipe fitting guide cover, and the cutting machine body is fixedly assembled on the main operating platform through a horizontal assembly frame.

[0008] Furthermore, the electrically controlled translation base includes an electrically controlled bidirectional lead screw movably mounted inside the embedded adjusting guide rail, and a first internal thread translation seat and a second internal thread translation seat threaded onto the electrically controlled bidirectional lead screw.

[0009] Furthermore, the combined pipe fitting guide cover includes a first arc-shaped support cover bolted to a first internal threaded translation seat and a second arc-shaped support cover bolted to a second internal threaded translation seat.

[0010] Furthermore, the first and second arc-shaped support covers have arc-shaped adjustment ports inside for assembling the electrically controlled sliding stabilizer cover.

[0011] Furthermore, the electrically controlled sliding stabilizer includes a sliding adjustment block slidably installed inside the arc-shaped adjustment port, an electrically controlled extrusion plate installed on the sliding adjustment block, and an external adjustment support rod for controlling the sliding adjustment block.

[0012] Furthermore, the first arc-shaped support cover and the second arc-shaped support cover have staggered lateral support protrusions on their adjacent surfaces.

[0013] Furthermore, optical recognition probes are mounted on both sides of the horizontal assembly frame via lateral mounting seats for locating and identifying the position and status of stainless steel pipe fittings.

[0014] Furthermore, arc-shaped guide grooves are provided on the inner walls on both sides of the arc-shaped adjustment port. The sliding adjustment block is inserted into the arc-shaped guide groove through the arc-shaped guide strips on both sides and slidably assembled with the arc-shaped adjustment port. The external adjustment support rod controls the sliding adjustment block to slide along the arc-shaped guide groove through telescopic control.

[0015] Furthermore, an arc-shaped recessed groove is provided on the inner arc surface of the sliding adjustment block. The electrically controlled extrusion plate includes an electrically controlled extrusion support rod fixed on the outside of the sliding adjustment block and a recessed extrusion plate located inside the arc-shaped recessed groove. The electrically controlled extrusion support rod controls the recessed extrusion plate by telescoping.

[0016] Furthermore, a retractable drive wheel assembly is elastically installed inside the arc-shaped adjustment port, and the sliding adjustment block slides inward to lock and limit the retractable drive wheel assembly.

[0017] The beneficial effects of this invention are as follows: This invention integrates feeding, support, and stabilization functions into a single guiding structure through the integrated design of an embedded adjustable guide rail and an electrically controlled translation base. This replaces traditional external independent clamping components, significantly simplifying the equipment structure, reducing installation space, and lowering assembly and maintenance costs. The electrically controlled bidirectional screw drives the translation base to self-adaptively support the pipe fitting guide cover. Combined with the sliding adjustment block of the electrically controlled sliding stabilizer cover sliding along the arc-shaped guide groove, multi-angle stable positioning is achieved. All mechanisms are uniformly linked and controlled by the electrical control system, realizing synchronous automated operation of the entire process of feeding, positioning, stabilization, and cutting, eliminating the need for manual step-by-step operation. An optical recognition probe provides real-time detection and feedback of the pipe fitting position, ensuring cutting accuracy. Combined with a retractable drive wheel set, it synchronously drives the pipe fitting for fixed-length feeding when locked in a stable position. This invention is suitable for large-scale, high-precision automated pipe fitting cutting processing. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to specific embodiments, but the present invention is not limited thereto.

[0024] like Figure 1As shown, the synchronous cutting machine of the present invention includes a main operating platform. Several horizontally arranged embedded adjusting guide rails 100 are fixedly mounted on the upper surface of the main operating platform, and an electrically controlled translation base 200 is movably mounted inside the embedded adjusting guide rails 100. A combined tubular guide cover 300 is mounted on the upper surface of the electrically controlled translation base 200, and an electrically controlled sliding stabilizer 400 is mounted on the combined tubular guide cover 300. The cutting machine body 500 is fixedly mounted on the main operating platform via a horizontal assembly frame 510.

[0025] like Figure 1 and Figure 2 As shown, the electrically controlled translation base 200 includes an electrically controlled bidirectional lead screw 210 movably mounted inside the embedded adjusting guide rail 100, and a first internal thread translation seat 211 and a second internal thread translation seat 212 threaded onto the electrically controlled bidirectional lead screw 210. The combined pipe fitting guide cover 300 includes a first arc-shaped support cover 310 bolted to the first internal thread translation seat 211 and a second arc-shaped support cover 311 bolted to the second internal thread translation seat 212. During operation, the electrically controlled bidirectional lead screw 210 rotates, driving the first internal thread translation seat 211 and the second internal thread translation seat 212 to translate towards or away from each other, thereby causing the first arc-shaped support cover 310 and the second arc-shaped support cover 311 to move closer or further apart, achieving adaptive support for pipe fittings of different diameters. The electrically controlled bidirectional lead screw 210 is driven by a servo motor, and the limit switches at both ends of the embedded adjusting guide rail 100 ensure precise and controllable translation stroke. The first arc-shaped support cover 310 and the second arc-shaped support cover 311 have staggered lateral support protrusions 315 on their adjacent surfaces, which are used to provide lateral restraint during pipe cutting and prevent pipe deflection. Figure 2 and Figure 3 As shown, the first arc-shaped support cover 310 and the second arc-shaped support cover 311 have arc-shaped adjustment ports 312 inside for assembling the electrically controlled sliding stabilizer cover 400. Arc-shaped guide grooves 313 are formed on the inner walls of both sides of the arc-shaped adjustment port 312. The electrically controlled sliding stabilizer cover 400 includes a sliding adjustment block 410 slidably mounted inside the arc-shaped adjustment port 312, an electrically controlled pressing plate 420 mounted on the sliding adjustment block 410, and an externally mounted adjustment support rod 430 for controlling the sliding adjustment block 410. The sliding adjustment block 410 is slidably assembled with the arc-shaped adjustment port 312 by inserting it into the arc-shaped guide groove 313 through arc-shaped guide strips 314 on both sides. The externally mounted adjustment support rod 430 controls the sliding adjustment block 410 to slide along the arc-shaped guide groove 313 by telescopic control, achieving precise positioning of the sliding adjustment block 410 within the arc-shaped adjustment port 312.

[0026] An arc-shaped recessed groove 411 is formed on the inner arc-shaped surface of the sliding adjustment block 410. The electrically controlled extrusion plate 420 includes an electrically controlled extrusion support rod 421 fixed to the outside of the sliding adjustment block 410 and a recessed extrusion plate 422 located inside the arc-shaped recessed groove 411. The electrically controlled extrusion support rod 421 controls the extension and retraction of the recessed extrusion plate 422 to push it out of the arc-shaped recessed groove 411. When the recessed extrusion plate 422 is pushed out, it fits tightly against the outer wall of the pipe to provide stable clamping; when it is retracted, the recessed extrusion plate 422 is completely housed in the arc-shaped recessed groove 411, without interfering with the free movement of the pipe.

[0027] The arc-shaped adjustment port 312 houses a retractable drive wheel assembly 440. When the sliding adjustment block 410 slides inward to the set position, the bottom of the sliding adjustment block 410 presses against the retractable drive wheel assembly 440, causing it to retract and lock, preventing it from retracting downward due to the weight of the pipe, thus facilitating normal support and transport. When the sliding adjustment block 410 slides outward to release, the retractable drive wheel assembly 440 elastically resets, and the outer wall of the pipe contacts it, compressing it downward. Simultaneously, the recessed extrusion plate 422 on the slid-out sliding adjustment block 410 presses downward against the outer wall of the pipe, maintaining the stability of the pipe during cutting. The retractable drive wheel assembly 440 achieves elastic extension and retraction through a built-in spring, and in drive mode, it is driven by a stepper motor via a synchronous belt, ensuring the fixed-length feed accuracy of the pipe.

[0028] like Figure 1 As shown, optical recognition probes 530 are mounted on both sides of the transverse assembly frame 510 via lateral mounting seats 520. The optical recognition probes 530 employ laser or infrared sensors to perform real-time positioning and identification of the stainless steel pipe fittings' position and status. During cutting, the optical recognition probes 530 detect the pipe fitting's feed position signal and feed it back to the electrical control system. The electrical control system then controls the electrically controlled sliding stabilizer 400 to achieve clamping stability, after which the cutting machine body 500 performs the cutting. After cutting is completed, the sliding adjustment block 410 slides outward and releases, and the retractable drive wheel set 440 elastically resets to drive the next section of pipe fitting to a fixed length, entering the next cutting cycle.

[0029] The synchronous cutting machine of the present invention operates as follows: The pipe enters the combined pipe guide cover 300. The first arc-shaped support cover 310 and the second arc-shaped support cover 311 automatically adjust their spacing according to the pipe diameter for adaptive support. After the cutting head of the cutting machine body 500 moves to the set position, the external adjustable support rod 430 of the electrically controlled sliding stabilizing cover 400 drives the sliding adjusting block 410 to slide inward along the arc-shaped guide groove 313. After reaching the set position, the retractable drive wheel set 440 is locked. Simultaneously, the electrically controlled extrusion support rod 421 drives the sinking extrusion plate 422 to push out and clamp the pipe. The cutting machine body 500 performs cutting. After completion, the sliding adjusting block 410 slides outward and releases. The retractable drive wheel set 440 elastically resets and drives the pipe to feed at a fixed length. All actions are uniformly coordinated by the programmable logic controller, realizing automated synchronous operation of the entire process of feeding, positioning, support, clamping, and cutting.
