Description

Technical Field

[0001] This invention relates to the field of metal pipe cutting technology, and more particularly to a vertical saw for processing metal shelves. Background Technology

[0002] Metal rack processing requires cutting long metal tubes into shorter sections to meet subsequent assembly needs. Tube cutting is a key pre-process in rack component production. The continuity of vertical sawing operations directly affects the overall production efficiency and processing accuracy of the racks. As a typical metal cutting and forming machine tool, the vertical saw is a core processing equipment in the intelligent manufacturing equipment industry under the high-end equipment manufacturing industry. The equipment is equipped with CNC blades and ensures the accuracy and quality of tube cutting through deep machining technology of cutting blades. It is currently the mainstream equipment for this process to adapt to large-scale processing. Chinese patent with announcement number "CN222660329U" discloses a vertical band saw for the end face of steel pipe bundles. The equipment is equipped with a main body, a fixing and driving mechanism, and relies on a motor and transmission components to drive the saw blade to complete the cutting. With the operating table slot, slide rail and control panel, stable processing of workpieces can be achieved. Based on mature metal cutting technology and forming machine tool processing principles, combined with matching blade processing technology, it has the advantages of automated clamping and cutting, high cutting accuracy and low material loss, which can effectively improve the production efficiency of batch cutting of pipes. However, this equipment has a core shortcoming when applied to the segmented cutting of long pipes for metal racks. The equipment lacks a continuous feeding structure and only supports single clamping and single cutting. After each cut, the pipe must be manually placed back on the workstation, adjusted, and positioned. Obviously, its overall cutting efficiency is poor when processing longer pipes. Even though it is equipped with basic CNC cutting inserts and cutting blades for deep machining, which can ensure the metal cutting accuracy of a single pipe segment, it cannot achieve continuous forming processing. This not only significantly increases labor costs and slows down batch processing, but also easily introduces dimensional errors due to repeated manual positioning. It cannot adapt to the continuous and large-scale pipe cutting production needs of metal racks and cannot meet the production requirements of high-end equipment manufacturing and intelligent manufacturing equipment industries for efficient and automated metal cutting forming machine tools. Therefore, it needs to be redesigned. Summary of the Invention

[0015] 2. During the application of this technical solution, by setting up a cutting feeding fixture in conjunction with a cutting positioning module and a buffer component, the distance of each push of the pipe can be changed by alternately controlling the opening and closing states of the two clamping structures. The buffer component can dissipate excess travel during the pushing process, preventing components from squeezing and jamming each other and hindering the operation of the equipment. The two clamping structures alternately lock the pipe to fix the placement position of the pipe, and the external dimensions of the pipe will not deviate after cutting. The processed pipe can be directly used for rack assembly without subsequent trimming, which can save unnecessary processing steps and further improve its processing convenience and efficiency. No manual feeding is required, which can improve the overall convenience of metal cutting processing, reduce the operating cost of forming machine tools, adapt to the development needs of high-end equipment manufacturing industry, and improve the processing and production efficiency in intelligent manufacturing equipment industry.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Example 1 A vertical saw for processing metal shelves, used as equipment in the intelligent manufacturing equipment industry, includes a base 1, a mounting seat 2 fixedly installed on the top of the base 1, and a cutting mechanism 3 fixedly installed on the top of the mounting seat 2. The cutting mechanism 3 includes a cutting module 31, a cutting positioning module 32, a pipe cutting and feeding module 33, and a linkage module 34. The cutting module 31 is fixedly installed on the top rear side of the mounting base 2, the cutting positioning module 32 is fixedly installed on the top front side of the mounting base 2, the cutting positioning module 32 is located directly below the cutting module 31, the linkage module 34 is located on one side of the cutting module 31, and the pipe cutting and feeding module 33 is fixedly connected to the base 1 on the side near the linkage module 34. The cutting module 31 is connected to the pipe cutting and feeding module 33 through the linkage module 34. The pipe cutting and feeding module 33 includes a side guide rail 331, which is fixedly connected to the base 1 on the side near the linkage module 34. A slide block 332 is slidably connected inside the side guide rail 331. A buffer assembly 333 is fixedly connected to the top of the slide block 332, and a cutting and feeding fixture 334 is fixedly connected to the top of the buffer assembly 333. The rear side of the slide block 332 is connected to the linkage module 34 via a transmission connection. During application, this device forms a complete operating system through multiple sets of functional modules that cooperate with each other within the cutting mechanism 3. This allows the power generated by the cutting action to be directly transmitted to the feeding stage. Through the transmission cooperation between the cutting module 31 and the pipe cutting and feeding module 33, the component holding the pipe can autonomously complete the pipe pushing action, eliminating the need for manual repetitive movement of the pipe to adjust the processing position. The linkage module 34 undertakes the power transmission between the two modules, enabling the pipe pushing action and the cutting action to be synchronized. The side guide rail 331 constrains the movement path of the slide 332, ensuring a uniform trajectory for the pipe being pushed. The buffer component 333 connected above the slide 332 absorbs excess thrust generated during the pushing process, preventing hard squeezing and jamming between components. The cutting and feeding fixture 334 directly supports the metal pipe to be cut, firmly stabilizing its position. The pipe will not shift position during its transport to the cutting area. The cutting positioning module 32 is positioned directly below the cutting operation, directly limiting and fixing the pipe after it is delivered to the correct position. The entire power transmission process relies on the linkage of the equipment's own components, eliminating the need for additional independent drive accessories to power the pipe pushing and reducing overall equipment accessory procurement costs. The pipe can be continuously transported to the cutting position following the pushing action, enabling uninterrupted pipe segment cutting operations and reducing the frequency of manual operation by on-site personnel.

[0020] Combination Figures 1-6As shown, the cutting module 31 includes a rear seat 311, which is fixedly connected to the top rear side of the mounting base 2. A concave seat 312 is fixedly connected to the top of the rear seat 311. A rotating shaft 313 is rotatably connected to the upper end of the concave seat 312. The outer end of the rotating shaft 313 is connected to the linkage module 34. A rotating frame 314 is fixedly connected to the outer surface of the rotating shaft 313. A mounting top 315 is fixedly installed on the top of the rotating frame 314. A cutting motor 316 is fixedly connected to the top of the mounting top 315. A gearbox 317 is provided at the front end of the cutting motor 316. A cutting housing 318 is fixedly installed on one side of the gearbox 317. An internal rotating connection is provided with a disc cutting saw 3110. The output end of the cutting motor 316 drives the disc cutting saw 3110 through a gearbox 317. An angle adjustment drive assembly 319 is provided on the rear side of the rear seat 311. The disc cutting saw 3110 is located above the cutting positioning module 32. The angle adjustment drive assembly 319 includes a rear frame 3191, which is fixedly connected to the rear side of the rear seat 311. A first electric cylinder 3192 is hinged to the rear end of the rear frame 3191. A rear hinge frame 3193 is fixedly installed on the output end of the first electric cylinder 3192. The output end of the first electric cylinder 3192 is hinged to the rear bottom of the mounting top seat 315 through the rear hinge frame 3193.

[0021] In the above-described embodiments of this application, during the application of this device, a base 1 is set to support all the upper components, and a mounting base 2 supports the entire cutting mechanism 3. The cutting mechanism 3 is divided into four parts: a cutting module 31, a cutting positioning module 32, a pipe cutting and feeding module 33, and a linkage module 34. The power generated by the operation of the cutting module 31 can be completely transmitted to the inside of the pipe cutting and feeding module 33 through the linkage module 34. Through the mutual transmission of power, the pipe cutting and feeding module 33 can be driven to perform reciprocating sliding operations. The slide 332 inside the pipe cutting and feeding module 33 slides linearly along the side guide rail 331. When the slide 332 moves, it can drive the upper buffer component 333 and the cutting and feeding clamp 334 to move synchronously. The cutting and feeding clamp 334 is used to hold and clamp the pipe to be processed. It can continuously transport the pipe to the cutting area following the movement of the slide 332. The power of the entire conveying system is taken from the kinetic energy generated by the cutting operation itself, which can save the expense of purchasing additional independent drive components. Operators do not need to manually move the pipe back and forth to complete the loading operation, which can reduce the labor input. The pipe conveying action can continue to follow the cutting action, and more pipe cutting operations can be completed per unit time. The buffer component 333 is arranged between the slide 332 and the cutting feeding fixture 334, which can bear the excess stroke margin during the sliding process and avoid the components squeezing each other and stopping during the sliding process. The pipe will not shift in position throughout the entire conveying process. After the pipe is sent into the cutting area, it can be directly fixed and cut by the cutting positioning module 32. The cooperation of the entire set of components can simplify the overall operation steps of pipe processing.

[0022] Example 2 Combination Figures 3-8 As shown, the linkage module 34 includes an outer connecting shaft 341, an outer connecting arm 342, and a transmission assembly 343. The outer connecting arm 342 is fixedly connected to the middle of one side of the concave seat 312. The outer connecting shaft 341 is rotatably connected to the upper end of the outer connecting arm 342. The inner end of the outer connecting shaft 341 is connected to the outer end of the rotating shaft 313 via a coupling. The transmission assembly 343 is fixedly connected to the back of the base 1 near the side guide rail 331. A linkage assembly 344 is provided on the outer side of the transmission assembly 343. The linkage assembly 344 is connected to the slide 332. The transmission assembly 343 includes a fixing member 3431 and a back side frame 34. 32. The fixing member 3431 is fixedly connected to the outer surface of the outer connecting shaft 341. The back side frame 3432 is fixedly connected to the rear side of the base 1 near the side guide rail 331. An arc-shaped bevel rack 3433 is fixedly installed on the rear side of the fixing member 3431. A bevel gear 3434 is rotatably connected to the upper end of the back side frame 3432. The bevel gear 3434 and the arc-shaped bevel rack 3433 are meshed. The linkage assembly 344 is rotatably connected to the upper rear end of the back side frame 3432. The outer end of the linkage assembly 344 is connected to the slide 332. The linkage assembly 344 includes a rotating block 3441. 41 is rotatably connected to the upper rear side of the back side frame 3432. A sleeve frame 3442 is fixedly connected to one side of the rotating block 3441. A linkage slide plate 3443 is slidably connected to the inner side of the sleeve frame 3442. A bending connecting frame 3444 is fixedly installed at the outer end of the linkage slide plate 3443. A drive shaft 3445 is rotatably connected to the outer end of the bending connecting frame 3444. The outer end of the drive shaft 3445 is rotatably connected to the rear side of the slide block 332. The buffer assembly 333 includes a fixed seat 3331, which is fixedly connected to the top of the slide block 332. The fixed seat 3331 has linearly arranged equal intervals on it. A buffer spring 3332 is fixedly connected to the column. A feed seat 3333 is fixedly connected to the side of the buffer spring 3332 near the cutting module 31. A cutting feed clamp 334 is fixedly connected to the top of the feed seat 3333. A support guide rod 3334 is fixedly connected to the side of the feed seat 3333 away from the cutting module 31 in a linear arrangement at equal intervals. A support guide sleeve 3335 is fixedly connected to the fixed seat 3331 in a linear arrangement at equal intervals. The support guide rod 3334 and the support guide sleeve 3335 are slidably connected to each other. Each buffer spring 3332 is sleeved on the outer surface of the support guide rod 3334.

[0023] In the above-described embodiments of this application, during the application of this device, the various components inside the linkage module 34 cooperate with each other to receive the rotational power output from the rotating shaft 313. After the rotating shaft 313 rotates, it can drive the outer connecting shaft 341 to rotate continuously via the coupling. The outer connecting arm 342 plays a role in rotational support for the outer connecting shaft 341. The rotating outer connecting shaft 341 will drive the fixing member 3431 to rotate together. The arc-shaped bevel rack 3433 mounted on the fixing member 3431 synchronously completes the reciprocating swing. The arc in the swing state The bevel rack 3433 continuously meshes with and drives the bevel gear 3434 to rotate. The bevel gear 3434 transmits power to the rotating block 3441, which in turn drives the sleeve frame 3442 to rotate. The linkage slide plate 3443 adaptively slides inside the sleeve frame 3442, thereby converting the circumferential rotational power into horizontal pushing and pulling power. The linkage slide plate 3443, through the bending connecting frame 3444 and the transmission shaft 3445, pulls the slide block 332 to complete the reciprocating sliding. During the sliding process of the slide block 332... This will drive the upper buffer assembly 333 and the cutting feed clamp 334 to move synchronously. Relying on the entire set of mechanical meshing transmission structure to transport pipe fittings, no additional power equipment is needed to supply feed power, which can reduce the overall equipment parts procurement cost. The movement rhythm of the slide 332 pushing the pipe fittings perfectly matches the cutting operation rhythm, and the operator does not need to manually push the pipe fittings, which can reduce on-site manpower consumption. The buffer assembly 333 is equipped with multiple sets of buffer springs 3332 based on the fixed base 3331, and the support guide rod 3334 is inserted into the support. The guide sleeves 3335 slide against each other inside, and the buffer springs 3332 are arranged on the outside of the support guide rod 3334. The feed seat 3333 receives the cutting feed clamp 334 and can absorb the excess thrust generated by the slide 332, so as to avoid the feed seat 3333 from hard contact with the surrounding components when it moves forward, causing the operation to jam. The pipe will not be displaced during the process of being clamped and pushed by the cutting feed clamp 334. The pipe fed into the cutting area can maintain a regular state and can realize continuous automatic feeding and cutting processing.

[0024] Example 3 Combination Figures 1-7As shown, the cutting feeding fixture 334 includes a feeding clamp 3341, which is fixedly connected to the top of the feeding base 3333. Second electric cylinders 3342 are fixedly installed at both ends of the feeding clamp 3341. A feeding clamp block 3343 is fixedly installed at the output end of the second electric cylinder 3342. A feeding clamp groove 3344 is formed on the inner side of the feeding clamp block 3343. The inner cavity of the feeding clamp groove 3344 has a V-shaped cross-section. The cutting positioning module 32 includes a positioning frame 321, which is fixedly connected to the top front side of the mounting base 2. The frame 321 is located below the cutting module 31. The front and back sides of the positioning frame 321 are fixedly connected to the third electric cylinder 322. The output end of the third electric cylinder 322 is fixedly installed with the pipe positioning clamp 323. The inner side of the pipe positioning clamp 323 is provided with a cutting positioning clamp groove 324. The overall cross-sectional shape of the cutting positioning clamp groove 324 is also V-shaped. The cutting positioning clamp groove 324 and the feeding clamp groove 3344 are provided with anti-slip textures at equal intervals. The top of the positioning frame 321 is located directly below the cutting module 31 and is provided with a cutting reserved groove 325.

[0025] In the above-described embodiments of this application, the device utilizes a cutting feeding clamp 334 and a cutting positioning module 32 in cooperation. This allows the two clamping structures to work together to fix and limit the pipe fitting during operation. During operation, the cutting feeding clamp 334 uses the extension and retraction of the second electric cylinders 3342 at both ends to bring the feeding clamping blocks 3343 together, allowing the pipe fitting to be clamped and fixed inside the feeding clamping groove 3344. The cutting positioning module 32 uses the third electric cylinders 322 arranged around the positioning frame 321 to open and close the pipe fitting positioning clamping blocks 323, enabling the pipe fitting end to be fed into the cutting position. The clamping mechanism is re-fixed. Both sets of clamping grooves adopt a V-shaped cross-section structure, which can accommodate tubular workpieces with different outer diameters. The anti-slip texture evenly distributed in the grooves can increase the contact friction between the pipe and the clamping groove, which can prevent the pipe from slipping or shifting during clamping and pushing. The two sets of clamping structures can alternately open and close according to the progress rhythm of the cutting process, which can flexibly control the feeding timing and feeding length of the pipe, reduce the number of manual correction steps for the pipe position, effectively reduce the workload of manual operation, and at the same time ensure that the pipe size is consistent for each cutting process, reduce the secondary trimming process after pipe processing, and save the overall material and time costs of processing.

[0026] The operating principle and advantages of this invention are as follows: During application, the operator places the long strip of pipe to be cut in the metal rack processing operation into the internal area of ​​the feeding clamp 3341. The operator pre-moves the pipe to adjust the depth of the front end of the pipe extending into the inner side of the positioning frame 321, thereby marking the initial cutting point. After the point adjustment is completed, the equipment simultaneously starts the operation of the second electric cylinder 3342 and the third electric cylinder 322. The second electric cylinders 3342 arranged on both sides simultaneously extend their rods outward, and the ends of the rods drive the feeding clamps 3343 to move closer to each other. The long strip of pipe is gathered and stored in the cavity of the feeding clamp groove 3344. The anti-slip texture arranged on the inner wall of the feeding clamp groove 3344 is close to the outer wall surface of the pipe, thereby firmly clamping and locking the rear half of the pipe. At the same time, the third electric cylinders 322 assembled around the positioning frame 321 extend simultaneously, and the pipe positioning clamps 323 mounted on the ends of the third electric cylinders 322 move closer to each other. The pipe fitting is brought together and its front end is embedded in the cutting positioning groove 324. The anti-slip texture on the inner side of the groove simultaneously conforms to the outer wall of the pipe fitting to complete the front end limit. The two clamping structures cooperate with each other to completely fix the entire pipe fitting. After all the displacement of the pipe fitting in all directions in space is constrained, the equipment officially starts the various operating actions of the cutting module 31 adapted to metal cutting operations. The first electric cylinder 3192 installed inside the angle adjustment drive component 319 begins to gradually extend its rod outward. The tail of the first electric cylinder 3192 is hinged to the inner end face of the rear frame 3191. The extended end of the first electric cylinder 3192 forms a hinged connection relationship with the bottom position of the rear hinge frame 3193 and the mounting top seat 315. This clamping and positioning method can effectively reduce manual alignment operations, reduce pipe fitting positioning deviation, improve the processing qualification rate of metal cutting forming machine tools, and truly adapt to the actual batch processing and production needs of high-end equipment manufacturing industry and intelligent manufacturing equipment industry.

[0027] As the first electric cylinder 3192 extends, it continuously pushes the mounting base 315 upwards. The mounting base 315, along with the rotating frame 314 fixed at the bottom, rotates circumferentially along the rotating shaft 313. The rotating shaft 313 rotates synchronously. As the rotating frame 314 flips downwards, the cutting motor 316, gearbox 317, cutting housing 318, and circular cutting saw 3110 fixed above the mounting base 315 all move downwards synchronously. The circular cutting saw 3110 gradually descends to the cutting slot reserved on the operating table. During this period, the cutting motor 316 is powered on and runs continuously. The rotational power output by the cutting motor 316 is transmitted to the gearbox 317. The gearbox 317 then redirects the power, driving the disc cutting saw 3110 to maintain high-speed rotation. The downward-moving disc cutting saw 3110 continuously contacts the pipe wall, completing metal cutting through the rotational cutting action of the saw body. This achieves single-pass pipe cutting, and after the entire pipe section is cut into a short section suitable for rack assembly, the single cutting process is complete. This automated cutting process can effectively shorten the time for single pipe cutting, significantly improve the processing efficiency of metal cutting forming machine tools, and effectively increase the mass production processing speed of pipes in the high-end equipment manufacturing industry and the intelligent manufacturing equipment industry.

[0028] After a single pipe cutting operation is completed, the first electric cylinder 3192 begins to retract its rod inward to reset. The retraction of the rod pulls the mounting top 315 and the rotating frame 314 to rotate in the opposite direction. The rotating shaft 313 rotates in the opposite direction and drives the circular cutting saw 3110 to lift upward. After the circular cutting saw 3110 is completely away from the pipe surface, the rotational motion at both ends of the rotating shaft 313 can be synchronously transmitted to the external connecting shaft 341 installed inside the linkage module 34. The external connecting shaft 341 follows the rotating shaft 313 to maintain the same amplitude of rotational motion. The fixing part 3431 fixedly installed on the outer wall of the external connecting shaft 341 continues to rotate. The arc-shaped bevel rack 3433 connected to the side of the fixing part 3431 follows the fixing part 3431 to perform a circular reciprocating swing. In this dynamic motion, the arc-shaped bevel rack 3433 and the bevel gear 3434 rotatably mounted on the upper end of the back side frame 3432 always maintain a meshing and engaging state. The oscillating motion of the arc-shaped bevel rack 3433 continuously drives the bevel gear 3434 to generate rotational motion. The rotational power of the bevel gear 3434 is transmitted to the rotating block 3441 mounted on the upper rear side of the back side frame 3432. The rotating block 3441 maintains a uniform rotation speed while driving the sleeve frame 3442 fixed to its side to rotate synchronously. This linkage reset structure does not require manual intervention for reset adjustment, and the entire process is automated, effectively reducing manual operation steps, improving the continuity of operation of metal cutting forming machine tools, and meeting the needs of continuous production in the high-end equipment manufacturing industry and the intelligent manufacturing equipment industry.

[0029] A sliding plate 3443 is slidably mounted inside the cavity of the sleeve frame 3442. During the circumferential rotation of the sleeve frame 3442, the sliding plate 3443 can slide freely inside the sleeve frame 3442 to adapt to changes in stroke. A bending connecting frame 3444 is fixedly connected to the outer end of the sliding plate 3443. A drive shaft 3445 is rotatably mounted at the end of the bending connecting frame 3444. The other end of the drive shaft 3445 is rotatably connected to the rear side of the slide block 332. The entire set of components works together to convert the circumferential rotational power into horizontal linear motion power. After being pulled by the power, the slide block 332 slides smoothly outward along the inner cavity of the side guide rail 331. The side guide rail 331 can constrain the travel trajectory of the slide block 332 throughout the entire process. To avoid misalignment during the sliding of the slide block 332, in the early stage of the slide block 332's outward sliding, the second electric cylinder 3342 pre-compresses, and the feeding clamps 3343 separate to release their clamping restraint on the rear half of the long tube. The third electric cylinder 322 maintains its extended position throughout the entire process, continuously clamping the front section of the tube. The long tube as a whole does not change position; only the buffer assembly 333 mounted on top of the slide block 332 and the cutting feeding clamp 334 slide outward together with the slide block 332 until the first electric cylinder 3192 fully retracts into place, the circular cutting saw 3110 returns to its initial high position, and the cutting feeding clamp 334 slides to the outermost limit point of the side guide rail 331. This stable power conversion structure can effectively reduce equipment sliding failures and processing errors, lower equipment failure rates and rework costs, stabilize the output efficiency of metal cutting forming machine tools, and adapt to the routine mass production processing of high-end equipment manufacturing industries and intelligent manufacturing equipment industries.

[0030] After the cutting feed clamp 334 reaches its outer limit position, the equipment restarts the second electric cylinder 3342 to extend outward, and the two side feed clamps 3343 re-clamp the long tube body. The feed clamp groove 3344 once again completes the clamping and fixing of the latter half of the tube. The equipment enters the preparation stage for the next metal cutting cycle. The first electric cylinder 3192 starts its extension stroke again, and the rotating shaft 313 rotates in the forward direction, driving the entire linkage transmission structure to operate again. The slide 332 is pulled by the power to slide horizontally along the side guide rail 331 toward the positioning frame 321. During the same period, the third electric cylinder 322 retracts its rod inward, and the pipe positioning clamps 323 separate completely, releasing the clamping limit of the cutting positioning module 32 on the front section of the pipe. The entire long pipe is clamped and constrained solely by the cutting feeding clamp 334. As the slide 332 continues to move, it will drag the long pipe towards the inside of the positioning frame 321. This cyclic feeding clamping structure enables uninterrupted continuous processing of pipes, significantly increasing the output per unit time of metal cutting forming machine tools, and effectively improving the overall production efficiency of the high-end equipment manufacturing industry and the intelligent manufacturing equipment industry.

[0031] After the pipe has traveled a predetermined distance, the third electric cylinder 322 extends its rod again to push the pipe positioning clamp 323 to close, re-clamping the front end of the pipe that has been pushed into place. The pipe is then double-clamped and fixed, awaiting metal cutting operations. The circular cutting saw 3110 moves downwards again to cut the pipe. During cutting, the equipment controls the second electric cylinder 3342 to retract and release the cutting feed clamp 334 from the pipe. The slide 332 continues to move forward slightly under the linkage force. The feed clamp 3341 gradually approaches the side wall surface of the positioning frame 321. After the feed clamp 3341 can no longer move forward, the traveling force of the slide 332 will directly act on the buffer assembly 333. The buffer assembly 333 contains multiple... The buffer spring 3332 is slightly compressed, and the support guide rod 3334 slides and extends within the support guide sleeve 3335 following the compression stroke. The support guide rod 3334 and the support guide sleeve 3335 can maintain the straight state of the buffer spring 3332 during the compression process. The buffer spring 3332 absorbs the excess thrust generated by the movement through its own deformation, which can prevent the feeding clamp 3341 and the positioning frame 321 from being rigidly squeezed and jammed. The circular cutting saw 3110 will not be affected by the travel resistance and can smoothly complete the pipe sawing process downward. The above-mentioned push, clamping and cutting process is continuously repeated, and the long pipe will be cut into multiple short pipes of uniform length until the entire raw material pipe is processed. The buffer structure can effectively avoid equipment jamming and jamming failures, reduce equipment downtime for maintenance, ensure the continuous and efficient operation of metal cutting forming machine tools, and stabilize the mass production progress of high-end equipment manufacturing industry and intelligent manufacturing equipment industry.

[0032] This device relies on the mechanical power generated by the cutting module 31 to drive the linkage module 34, which in turn drives the pipe cutting and feeding module 33 to complete the pipe feeding action. The entire feeding action is achieved through the interconnection of internal components of the machine, and the pipe is automatically pushed through a purely mechanical transmission method. No additional drive components are needed to provide feeding power, effectively reducing equipment parts procurement costs and subsequent maintenance costs. This significantly improves the operating efficiency of metal cutting and forming machine tools, meeting the production needs of high-end equipment manufacturing and intelligent manufacturing equipment industries for efficient batch processing of pipes. Each pipe feed maintains a fixed travel length, enabling uninterrupted segmented cutting of long pipes to meet metal cutting requirements. Compared to relying on manual pushing of pipes or adding external components such as conveyor belts or robotic arms for pipe transport, the purely mechanical linkage feeding structure operates more smoothly, ensuring consistent pipe travel distance each time. Throughout the process, operators do not need to repeatedly move the pipes for positioning and clamping, significantly reducing manual operation input and lowering labor costs. The equipment has no unnecessary external drive electronic components, and the component layout is simple, making disassembly and maintenance easier in case of daily malfunctions, further reducing equipment operating costs. During operation, the onboard distance sensor and PLC controller can detect the movement of the pipe in real time. Once the pipe is pushed to the corresponding length, the cutting positioning module 32 is triggered to clamp and fix the pipe, thus adapting to processing requirements for different cutting lengths. The entire feed power is derived from the mechanical transmission effect generated by the lifting and rotating motion of the circular cutting saw 3110, eliminating the need for an additional power source to drive the feeding structure. It can stably complete the continuous cutting and processing of metal rack pipes, effectively improving the automation level and mass production capacity of metal cutting and forming machine tools, and further enhancing the pipe processing efficiency of the high-end equipment manufacturing industry and the intelligent manufacturing equipment industry.
