Description

Technical Field

[0001] This invention relates to the field of cutting machines, and more particularly to a flying cutting device for metal square tubes. Background Technology

[0002] Flying cutter is a specialized device that can cut materials in continuous motion. Its core lies in the synchronous control system, which enables the cutting device to precisely match the speed of the material, achieving high-speed and precise cutting without stopping the machine.

[0003] Currently, flying cut technology still relies on manual processes. It requires manual measurement of materials using tools such as tape measures to determine the cutting position, manual adjustment of the starting timing and movement speed of the cutting mechanism, and manual operation of the cutting machine to cut the materials.

[0004] Regarding the aforementioned technologies, the cutting process is limited by human factors, requiring frequent reductions in material conveying speed to accommodate manual operation, which reduces work efficiency and leaves room for improvement. Summary of the Invention

[0005] To improve the efficiency of cutting operations, this invention provides a metal square tube flying cutter, employing the following technical solution:

[0006] A metal square tube flying cutter includes a frame and a transmission device mounted on the frame for guiding and transmitting materials, a cutting device for cutting materials, a blowing device for cooling the cutting process, and a dust collection device for collecting and recycling debris.

[0007] The transmission device includes a transmission mechanism supported on the bottom of the material and used to assist in transporting the material, a fixing mechanism located on one side of the transmission mechanism, a roller mechanism located on the other side of the transmission mechanism and cooperating with the fixing mechanism to clamp the material and drive the transmission, and a clamping mechanism connected to the transmission mechanism and used to drive the roller mechanism to move horizontally closer to the fixing mechanism to clamp the material.

[0008] By adopting the above technical solution, the transmission device achieves stable clamping and continuous transmission of materials through the coordinated action of the conduction mechanism, fixing mechanism, and roller mechanism. Combined with the horizontal drive of the clamping mechanism, it can be adapted to metal square tubes of various specifications. The cutting device cuts the transmitted materials, and the blowing device follows the cutting device to cool down in real time to avoid overheating of the cutting area. The dust collection device collects debris and dust simultaneously. No manual work is required, which improves the working efficiency of metal square tube cutting, while ensuring cutting quality and a clean working environment.

[0009] Optionally, the conveying mechanism includes a conveying frame mounted on the machine frame and a roller mounted on the conveying frame for conveying materials;

[0010] The fixing mechanism includes a fixed shaft spaced apart on the transmission frame, a rotating shaft rotatably mounted on the fixed shaft, a rotating shaft sleeve sleeved outside the rotating shaft, and a third compression spring disposed on the rotating shaft. The third compression spring supports the rotating shaft to separate the rotating shaft sleeve from the transmission frame.

[0011] By adopting the above technical solution, the rollers on the conveyor frame provide rolling support for the material, reducing frictional resistance during material transmission. Together with the roller mechanism, the material is transported smoothly. When the material comes into contact with the rotating shaft sleeve, the third compression spring always presses the rotating shaft upward. The third compression spring supports the rotating shaft, separating the rotating shaft sleeve from the conveyor frame, forming elastic support, and avoiding friction caused by the contact between the rotating shaft sleeve and the conveyor frame, which would hinder the material's progress.

[0012] Optionally, the roller mechanism includes a roller frame plate disposed above the roller shaft and moving horizontally relative to the roller shaft, a roller disk fixedly mounted on the roller frame plate, a roller disposed circumferentially on the roller disk and slidably mounted, and a drive assembly for driving the roller to move.

[0013] The roller disk has a circumferentially open slide for the rollers to slide, and adjacent rollers abut against each other to transmit driving force;

[0014] The outer side of the roller abuts against the material and presses the material against the rotating shaft sleeve. The roller drives the material forward during the sliding process.

[0015] By adopting the above technical solution, the circumferential rollers of the roller disc are slidably installed through the slide rail, and the adjacent rollers abut to form a closed-loop transmission structure. When the drive component drives the rollers to slide, the rollers continuously and intermittently rub against the material surface to generate a forward driving force, which, together with the fixing mechanism, enables the clamping and transmission of materials to be carried out simultaneously.

[0016] Optionally, the roller disk includes an upper support disk, a lower support disk, and a support rod connecting the two; the roller is located between the upper support disk and the lower support disk;

[0017] The drive assembly includes a sleeve fitted on the outside of the support rod, a lever fixedly connected to the sleeve, and a roller motor that drives the sleeve to rotate; the lever abuts against the roller, and one rotation of the lever drives one roller to move;

[0018] The drive assembly is provided in two sets, located at both ends of the roller disk. When one lever abuts against the roller, the other lever separates from the roller.

[0019] By adopting the above technical solution, the upper support plate, lower support plate and support rod ensure the stability of the roller during sliding; in the drive assembly, the roller motor drives the sleeve and lever to rotate, and the lever periodically pushes the roller to slide along the slide. The two sets of drive assemblies work alternately to realize the continuous cyclic sliding and rotation of the roller, providing a continuous driving force for the material transfer.

[0020] Optionally, the clamping mechanism includes a fixed base fixedly mounted on the guide frame, a sliding base horizontally slidably mounted on the guide frame and fixedly connected to the roller frame plate, a sliding frame vertically mounted between the fixed base and the sliding base, and a lifting motor for driving the sliding frame to move up and down;

[0021] The fixed base has a vertically formed longitudinal sliding groove to guide one end of the sliding frame to slide vertically; the sliding base has an inclined sliding groove to drive the other end of the sliding frame to slide at an incline so that the sliding base can be displaced horizontally.

[0022] The fixed base and the sliding base are arranged in parallel; the fixed base is slidably connected to the roller frame plate to guide the horizontal displacement of the roller mechanism.

[0023] By adopting the above technical solution, when the lifting motor drives the sliding frame to lift, one end of the sliding frame connected to the fixed mechanism slides vertically along the longitudinal sliding groove of the fixed base, and the other end connected to the roller mechanism slides obliquely along the inclined sliding groove of the sliding base. The guiding effect of the inclined sliding groove converts the vertical motion into the horizontal displacement of the sliding base, thereby driving the roller mechanism to move horizontally. In conjunction with the fixed mechanism, it realizes the clamping and releasing of materials, and is suitable for materials of various shapes and specifications.

[0024] Optionally, the cutting device includes a cutting wheel, a lifting mechanism for driving the cutting wheel to rise and fall, a sliding mechanism for driving the cutting wheel to move horizontally, and an auxiliary mechanism for assisting the cutting wheel to rise and fall.

[0025] The lifting mechanism includes a lifting frame that is mounted on the frame and used for horizontal movement of the cutting wheel, and a lifting cylinder that is mounted on the frame and connected to the cutting wheel.

[0026] The sliding mechanism includes a movable block that is slidably mounted on the frame and a sliding cylinder that is fixedly mounted on the frame and connected to the movable block. The lifting cylinder is mounted on the frame via the movable block.

[0027] The auxiliary mechanism includes a drive rod rotatably mounted on the frame, a drive gear rotatably mounted on the frame, and an auxiliary motor detachably connected to the drive gear and used to drive the drive gear to rotate; the drive gear is provided with a first rotating rod, which is eccentrically arranged with respect to the drive gear; the drive rod has a first transverse groove for the lifting frame to pass through and slide laterally, and a second transverse groove for the first rotating rod to pass through and slide laterally; the drive gear drives the drive rod to swing back and forth to drive the cutting wheel to rise and fall.

[0028] By adopting the above technical solution, the lifting cylinder of the lifting mechanism drives the cutting wheel to move up and down to achieve the cutting action, and the sliding cylinder of the sliding mechanism drives the moving block and the cutting wheel to move horizontally to adapt to different cutting positions; in the auxiliary mechanism, the auxiliary motor drives the drive gear to rotate, and the eccentrically set first rotating rod drives the drive rod to swing back and forth, providing auxiliary lifting force to the lifting frame through the first transverse groove; thus avoiding the cutting wheel from deviating during cutting and ensuring the stability and accuracy of the lifting action.

[0029] Optionally, a lifting mechanism for supporting the material during cutting may also be included;

[0030] The lifting mechanism includes a lifting roller assembly that is mounted on the frame and used to support the material to be cut, a lifting rod that is rotatably mounted on the frame and whose end is rotatably connected to the lifting roller assembly, and a driven wheel that is rotatably mounted on the frame.

[0031] The driven wheel is provided with a second rotating rod, which is eccentrically positioned with respect to the driven wheel; the lifting rod is provided with a third transverse groove through which the second rotating rod passes and slides laterally;

[0032] The driven wheel meshes with the drive gear to allow the cutting wheel and the lifting roller assembly to move away from or closer to each other during cutting.

[0033] By adopting the above technical solution, the lifting mechanism is linked with the cutting device through the meshing of the driven wheel and the drive gear. While driving the drive gear to rotate and control the cutting wheel to cut, it simultaneously drives the driven wheel to rotate and control the lifting roller group to intermittently lift upwards to support the material being cut. After cutting, the cutting wheel rises and the lifting roller group descends synchronously without affecting the continued material transport. The supporting effect of the lifting roller group avoids the cutting angle tilting or deformation caused by the material being exposed too long during cutting, ensuring a flat cut. At the same time, the roller structure does not affect the continuous feeding of the material, thus improving the cutting quality and working efficiency.

[0034] Optionally, the cutting wheel has a cutting area for cutting materials; the blowing device includes a blowing seat that is slidably mounted on the lifting frame and connected to the cutting wheel, a blowing head mounted on the blowing seat and always pointing towards the cutting area, an air box set on the frame for providing air source to the blowing head, and a connecting pipe connecting the air box and the blowing seat.

[0035] The connecting pipe is fitted with a moving block to avoid interference between the connecting pipe and the cutting wheel during displacement.

[0036] By adopting the above technical solution, the blower base moves up and down synchronously with the lifting frame and moves horizontally synchronously with the cutting wheel, ensuring that the blower head is always pointing towards the cutting area, blowing away the heat and debris generated during cutting in real time, avoiding damage to the cutting wheel caused by high temperature, and also avoiding damage to the material and cutting wheel caused by debris residue; the connecting pipe is arranged with moving blocks to keep the pipe from the blower base to the blower head in a taut state, avoiding the pipe being too long and getting tangled or interfering when the cutting device moves, ensuring smooth airflow, improving the working stability of the blower device, and ensuring the cooling and debris removal effect.

[0037] Optionally, the frame has a conveying area for conveying materials and a processing area for cutting materials, and a baffle is provided between the conveying area and the processing area, and the baffle has a material passage for materials to pass through.

[0038] The dust collection device includes a dust collection trough located at the bottom of the processing area, a dust collection box located at the bottom of the conveying area, a dust collection pipe connecting the dust collection trough and the dust collection box, and a dust collection fan connected to the dust collection pipe and having a filter screen.

[0039] When materials are cut by the cutting wheel in the processing area, the debris and dust generated fall into the dust collection trough, and the dust is sucked from the dust collection trough into the dust collection box by the dust suction fan for collection and treatment.

[0040] By adopting the above technical solution, the baffle isolates the conveying area from the processing area, preventing the spread of debris and dust to the conveying area and affecting material transmission; the debris generated by cutting falls directly into the dust collection trough at the bottom of the processing area, and the dust is sucked into the dust collection box by the dust suction fan. The filter screen can filter the dust, realizing the centralized collection and recycling of debris, reducing dust pollution, facilitating the recycling of debris, reducing material waste, and preventing debris accumulation from affecting equipment operation.

[0041] Optionally, a folding door is installed on the frame; the folding door includes a door frame installed on the frame, a connecting door rotatably installed on the top of the door frame, a sliding door hinged to the connecting door and sliding on the door frame, a spring lock structure provided on the side of the sliding door, and a fixed switch mechanism for locking the spring lock structure and the door frame.

[0042] The door frame is provided with a vertical sliding groove and a horizontal locking groove that communicates with the sliding groove;

[0043] The spring lock structure includes a sliding block that is telescopically installed on the sliding door and inserted into the sliding groove, a first compression spring that drives the sliding block to always extend out of the sliding door, and a sliding rod that controls the sliding of the sliding block.

[0044] The fixed switch mechanism includes a pressing column and a locking column that are vertically and vertically installed in the locking groove, a second compression spring that drives the pressing column to always spring upward, and a connecting rod that is horizontally slidably installed in the locking groove to drive the locking column and the pressing column to extend and retract in opposite directions.

[0045] Both the pressing post and the locking post are equipped with slide rails that slide with the connecting rod. The two slide rails are inclined in opposite directions so that when the pressing post is pressed and moves down, the connecting rod drives the locking post to move up.

[0046] The locking pin is located at one end of the locking groove near the sliding groove.

[0047] By adopting the above technical solution, the folding door facilitates subsequent equipment maintenance: the connecting door rotates in conjunction with the sliding door sliding along the sliding groove of the door frame, completely sealing the processing area when closed, and folding away for storage when open, without occupying space or hindering the transport of metal square tubes and equipment maintenance; the spring-loaded lock structure and fixed switch mechanism lock the folding door when it is opened, the first compression spring drives the sliding block to automatically pop out and insert into the sliding groove, and when the pressing column is pressed, the connecting rod slides horizontally through the inclined slide rail, and the connecting rod then drives the locking column to move upward through the reverse inclined slide rail, engaging and locking with the sliding block, preventing the folding door from falling during operation, which improves equipment safety without affecting work efficiency.

[0048] In summary, this application includes at least one of the following beneficial technical effects:

[0049] 1. Through the coordinated operation of the transmission mechanism, fixing mechanism, and roller mechanism, stable clamping and continuous transmission of materials are achieved. Combined with the horizontal drive of the clamping mechanism, it can be adapted to various specifications of metal square tubes.

[0050] 2. The supporting function of the lifting roller assembly prevents the cutting angle from tilting or deformation caused by excessive exposed material length during cutting, ensuring a smooth cut. At the same time, the roller structure does not affect the continuous feeding of material, improving cutting quality and work efficiency.

[0051] 3. The eccentrically positioned first rotating rod drives the drive rod to reciprocate, providing auxiliary lifting force to the lifting frame through the first transverse groove; this prevents the cutting wheel from shifting during cutting, ensuring the stability and accuracy of the lifting action.

[0062] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0063] Reference Figure 1A metal square tube flying cutter includes a frame 1, a conveying device 2, a cutting device 3, a blowing device 4, and a dust collection device 5. The conveying device 2, cutting device 3, blowing device 4, and dust collection device 5 are all mounted on the frame 1. The frame 1 has a conveying area 10 for conveying materials and a processing area 11 for cutting materials. A baffle 12 is provided between the conveying area 10 and the processing area 11, and the baffle 12 has a material passage for material to pass through. The conveying device 2 is located in the conveying area 10 and is used for guiding and transmitting materials. The cutting device 3 is located in the processing area 11 and is used for cutting materials. The blowing device 4 is mounted on the cutting device 3 and assists in cooling the cutting device 3. The dust collection device 5 is located at the bottom of the processing area 11 and is used to collect and recover debris.

[0064] Reference Figure 2 The conveying device 2 includes a transmission mechanism 20, a fixing mechanism 21, a roller mechanism 22, and a clamping mechanism 23. The transmission mechanism 20 is located at the bottom of the conveying area 10. The transmission mechanism 20 is used to support the bottom of the material and assist in carrying the material. The fixing mechanism 21 is located on one side above the transmission mechanism 20, and the roller mechanism 22 is located on the other side above the transmission mechanism 20. It cooperates with the fixing mechanism 21 to clamp the material and drive the transmission. The clamping mechanism 23 is arranged above the fixing mechanism 21 and the roller mechanism 22, and is used to drive the roller mechanism 22 to move horizontally closer to the fixing mechanism 21 to clamp the material.

[0065] Reference Figure 2 The conveying mechanism 20 includes a conveying frame 200 and a roller 201. The conveying frame 200 is located on one side of the roller 201, and a metal tube is welded to the bottom of the conveying frame 200. The roller 201 is mounted on the metal tube and is used to assist the roller mechanism 22 in carrying materials. The roller 201 can be passively rotated under the drive of the material, or a sprocket and chain structure can be installed on the roller 201 and driven by a motor to assist the roller mechanism 22 in carrying materials.

[0066] Reference Figure 2 The roller mechanism 22 includes a roller frame 220, a roller disk 221, rollers 222, and a drive assembly 223. The roller frame 220 is positioned above the roller shaft 201 and moves horizontally relative to it. The roller disk 221 is fixedly installed below the roller frame 220 and flush with the top of the guide frame 200. The rollers 222 are circumferentially arranged and slidably mounted in the middle of the roller disk 221. The roller disk 221 has circumferentially opened slideways 2210 for the rollers 222 to slide, and adjacent rollers 222 abut against each other. The drive assembly 223 is disposed in the roller disk 221 and drives the rollers 222 to move. The rollers 222 abut against the material and press the material against the rotating sleeve 212 of the fixed structure.

[0067] Reference Figure 3The fixing mechanism 21 includes a fixed shaft 210, a rotating shaft 211, a rotating shaft sleeve 212, and a third compression spring 213. The fixed shaft 210 is fixed at intervals on the guide frame 200, and the rotating shaft 211 is rotatably mounted on the fixed shaft 210, with a hollow cavity inside. The rotating shaft sleeve 212 is made of rubber and is sleeved on the outside of the rotating shaft 211, abutting against the material. The third compression spring 213 is disposed inside the hollow cavity of the rotating shaft 211, and the third compression spring 213 always presses the rotating shaft 211 upward. The third compression spring 213 supports the rotating shaft 211, separating the rotating shaft sleeve 212 from the guide frame 200, forming an elastic support, and preventing the rotating shaft sleeve 212 from contacting the guide frame 200 and causing friction, thus hindering the material's movement.

[0068] Reference Figure 4 The roller disk 221 includes an upper support disk 2211, a lower support disk 2212, and a support rod 2213. The support rod 2213 is fixed between the upper support disk 2211 and the lower support disk 2212, and is located on the vertical line of the upper center of the support disk, supporting and balancing the upper support disk 2211 and the lower support disk 2212. The roller 222 is located between the upper support disk 2211 and the lower support disk 2212, and its two ends slide with the upper support disk 2211 and the lower support disk 2212 respectively, making the operation of the roller 222 more stable.

[0069] Reference Figure 4 The drive assembly 223 includes a sleeve 2230, a lever 2231, and a roller motor 2232. The sleeve 2230 is sleeved on the outside of the support rod 2213, and the lever 2231 is fixedly connected to the sleeve 2230, with a length that can reach the roller 222. The roller motor 2232 is located above the upper support plate 2211, and is connected to the sleeve 2230 through a gear structure to drive the sleeve 2230 to rotate.

[0070] The lever 2231 rotates one revolution, causing one roller 222 to move along the slide rail 2210, while simultaneously moving the other rollers 222 together. In this embodiment, two sets of drive components 223 are provided, located at opposite ends of the roller disk 221. When one lever 2231 abuts against the roller 222, the other lever 2231 separates from the roller 222. The two sets of drive components 223 work alternately, rotating in the same direction and at a synchronous speed, periodically pushing the rollers 222 to slide along the slide rail 2210, achieving continuous cyclic sliding and rotation of the rollers 222, providing a continuous driving force for material transfer.

[0071] Reference Figure 5 and Figure 6The clamping mechanism 23 includes a fixed base 230, a sliding base 231, a sliding frame 232, and a lifting motor 233. The fixed base 230 and the sliding base 231 are arranged in parallel. One end of the fixed base 230 is fixedly connected to the transmission frame 200 by bolts, and the other end is horizontally slidably connected to the upper support plate 2211. One end of the sliding base 231 is horizontally slidably connected to the transmission frame 200, and the other end is fixedly connected to the upper support plate 2211 by bolts.

[0072] The sliding frame 232 is vertically positioned between the fixed base 230 and the sliding base 231, and sliding rods are fixedly installed on both sides of the sliding frame 232 near the fixed base 230 and the sliding base 231. The lifting motor 233 is mounted on the frame 1, and the output shaft of the lifting motor 233 is fixed to the top of the sliding frame 232, driving the sliding frame 232 to rise and fall.

[0073] Reference Figure 5 and Figure 6 The fixed base 230 has a vertically formed longitudinal sliding groove 2300 to guide the sliding rod on the side near the fixed base 230 to slide vertically. The sliding base 231 has an inclined sliding groove 2310 to drive the sliding rod on the side of the sliding frame 232 near the fixed base 230 to slide at an incline so that the sliding base 231 can be displaced horizontally.

[0074] When the sliding frame 232 is raised or lowered, the control slide rod slides in the longitudinal slide groove 2300 and the inclined slide groove 2310 to control the roller mechanism 22 to move closer to the fixed mechanism 21 to clamp the material.

[0075] Reference Figure 7 The cutting device 3 includes a cutting wheel 30, a lifting mechanism 31, and an auxiliary mechanism 33. The cutting wheel 30 is used to cut materials. The lifting mechanism 31 is mounted on the frame 1 to drive the cutting wheel 30 to move up and down. The sliding mechanism 32 is used to drive the cutting wheel 30 to move horizontally. The auxiliary mechanism 33 is used to assist the cutting wheel 30 in moving up and down. The cutting device 3 may be equipped with a sensor to detect the position of the material. When the sensor detects that the material has reached a specified length, the material transmission is stopped and cutting is performed. After the cutting is completed, the material transmission continues and the material length is sensed again.

[0076] Reference Figure 7 The lifting mechanism 31 includes a lifting frame 310 and a lifting cylinder 311. The lifting frame 310 is mounted on the frame 1 and has a lifting rod 3100 that can be vertically lifted. The cutting wheel 30 is mounted on the lifting rod 3100 and can move horizontally on it. The lifting cylinder 311 is disposed on the frame 1 and connected to the cutting wheel 30.

[0077] Reference Figure 7The sliding mechanism 32 includes a moving block 320 and a sliding cylinder 321. The sliding cylinder 321 is fixedly installed on the frame 1. The moving block 320 is slidably installed on the frame 1 and connected to the piston rod of the sliding cylinder 321. The lifting cylinder 311 is installed on the frame 1 through the moving block 320.

[0078] Reference Figure 7 The auxiliary mechanism 33 includes a drive rod 330, a drive gear 331, and an auxiliary motor 332. The drive gear 331 is rotatably mounted on the frame 1, and the auxiliary motor 332 is detachably connected to the drive gear 331 and is used to drive the drive gear 331 to rotate. A first rotating rod 3310 is provided on the drive gear 331, and the first rotating rod 3310 is eccentrically arranged with respect to the drive gear 331.

[0079] The drive rod 330 is rotatably mounted on the frame 1. The drive rod 330 has a first transverse groove 3300 through which the lifting rod 3100 passes and slides laterally, and a second transverse groove 3301 through which the first rotating rod 3310 passes and slides laterally.

[0080] When the lifting cylinder 311 drives the cutting wheel 30 to rise and fall, the drive rod 330 is restricted by the first rotating rod 3310 and performs a reciprocating swing motion.

[0081] The auxiliary motor 332 is not started under normal circumstances, and its shaft can rotate freely. When the lifting cylinder 311 malfunctions, the auxiliary motor 332 can provide power. When the auxiliary motor 332 is started, it drives the drive gear 331 to rotate, which in turn drives the drive rod 330 to swing back and forth, thereby enabling the cutting wheel 30 to rise and fall.

[0082] Reference Figure 7 The lifting mechanism 34 includes a lifting roller assembly 340, a lifting rod 341, and a driven wheel 342. The lifting roller assembly 340 is vertically mounted on the frame 1 to support the material to be cut. The driven wheel 342 is rotatably mounted on the frame 1 and meshes with a drive gear 331. The lifting rod 341 is rotatably mounted on the frame 1 and its end is rotatably connected to the lifting roller assembly 340. A second rotating rod 3420 is provided on the driven wheel 342, and the second rotating rod 3420 is eccentrically positioned with respect to the driven wheel 342. The lifting rod 341 has a third transverse groove 3410 through which the second rotating rod 3420 passes and slides laterally. The driven wheel 342 is controlled by the drive gear 331 to move the cutting wheel 30 and the lifting roller assembly 340 away from or closer to each other during cutting.

[0083] Reference Figure 1 and Figure 7The cutting wheel 30 has a cutting area for cutting materials. The blowing device 4 includes a blowing base 40, a blowing head 41, an air box 42, and a connecting pipe 43. The blowing base 40 is slidably mounted on the lifting rod 3100 and connected to the cutting wheel 30. The blowing head 41 is mounted on the blowing base 40 and always points towards the cutting area. The air box 42 is mounted on the frame 1 and is used to provide air to the blowing head 41. The connecting pipe 43 connects the air box 42 and the blowing base 40, and the connecting pipe 43 passes through the moving block 320. The connecting pipe 43 is a telescopic pipe that can be extended or shortened to adapt to the horizontal sliding of the cutting machine, so that the pipe from the blowing base 40 to the blowing head 41 is always kept taut, avoiding the pipe from being too long and getting tangled or interfering when the cutting device 3 moves, and ensuring unobstructed airflow.

The folding door 14 includes a door frame 140, a connecting door 141, a sliding door 142, a spring-loaded locking structure 143, and a fixed switching mechanism 144. The door frame 140 is installed on the frame 1, the connecting door 141 is rotatably installed on the top of the door frame 140, and the sliding door 142 is hinged to the connecting door 141 and slides on the door frame 140. The spring-loaded locking structure 143 is symmetrically arranged on both sides of the sliding door 142 and is used for the removal and installation of the sliding door 142. The fixed switching mechanism 144 is provided on the door frame 140 and is used to lock the spring-loaded locking structure 143 and the door frame 140.

[0087] Reference Figure 8 The door frame 140 has a vertical sliding groove 1400 and a horizontal locking groove 1401 that communicates with the sliding groove 1400.

[0088] Reference Figure 9The spring-loaded locking structure 143 includes a sliding block 1430, a first compression spring 1431, and a sliding rod 1432. The sliding block 1430 is telescopically mounted on the sliding door 142 and engages with the sliding groove 1400. The first compression spring 1431 drives the sliding block 1430 to always extend out of the sliding door 142. The sliding rod 1432 is slidably mounted on the sliding door 142 and connected to the sliding block 1430. The sliding rod 1432 is used to control the sliding of the sliding block 1430. The sliding door 142 has a moving groove for the telescopic movement of the sliding block 1430.

[0089] Reference Figure 8 The fixed switch mechanism 144 includes a pressing post 1440, a locking post 1441, a second compression spring 1442, and a connecting rod 1443. The pressing post 1440 is vertically and vertically installed in the locking groove 1401 at one end away from the sliding groove 1400. The locking post 1441 is vertically and vertically installed in the locking groove 1401 at one end near the sliding groove 1400. The second compression spring 1442 is located below the pressing post 1440, driving the pressing post 1440 to always spring upward. A partition is provided between the pressing post 1440 and the locking post 1441. The connecting rod 1443 passes through the partition and can slide horizontally in the locking groove 1401 to drive the locking post 1441 and the pressing post 1440 to extend and retract in opposite directions.

[0090] Reference Figure 8 Both the pressing post 1440 and the locking post 1441 are provided with slide rails 14400 that slide with the connecting rod 1443. The two slide rails 14400 are inclined in opposite directions so that when the pressing post 1440 is pressed and moves down, the connecting rod 1443 drives the locking post 1441 to move up.

[0091] Reference Figure 8 When the sliding block 1430 slides into the locking groove 1401, it presses down on the pressing post 1440 and controls the locking post 1441 to rise via the connecting rod 1443, thereby locking the sliding block 1430 in the sliding groove 1400. When the sliding block 1430 is driven to retract by the sliding rod 1432, the second compression spring 1442 drives the pressing post 1440 to rise, and the connecting rod 1443 controls the locking post 1441 to fall, thereby unlocking the sliding block 1430.

[0092] The implementation principle of a metal square tube flying cutter according to an embodiment of this application is as follows: the transmission device 2 reduces friction through the rolling support of the roller shaft 201 of the transmission mechanism 20, and is elastically supported by the third compression spring 213 of the fixing mechanism 21 to form a flexible clamping base that can adapt to square tubes of various specifications; the clamping mechanism 23 controls the sliding frame 232 to rise and fall through the cylinder, and the sliding rod drives the roller mechanism 22 to approach the fixing mechanism 21 in the longitudinal sliding groove 2300 and the inclined sliding groove 2310 to clamp the material stably; then through the alternating working drive component 223, the roller 222 is driven to slide continuously along the slide 2210, and the friction between the roller 222 and the material is used to provide intermittent and continuous thrust.

[0093] The cutting device 3 adjusts the lifting and horizontal positions of the cutting wheel 30 through the lifting mechanism 31 and the sliding mechanism 32 to adapt to different cutting needs; the eccentric gear of the auxiliary mechanism 33 is linked with the drive rod 330 to provide auxiliary force for the lifting of the cutting wheel 30, avoiding vibration during cutting and causing the cut to be skewed; the lifting mechanism 34 and the cutting device 3 move synchronously through gear meshing. When the cutting wheel 30 descends, the lifting roller group 340 rises synchronously to support the material cutting part, preventing the material from deforming due to its own weight or cutting force. After cutting is completed, they descend synchronously without affecting the continuous transmission of materials, achieving precise matching between cutting and support.

[0094] The material is transported by the transport device at a set speed. When the cutting length is reached, the drive component 223 stops driving the roller mechanism 22 to rotate before the cutting wheel 30 cuts, so that the material is in a stable and stationary state during cutting, preventing the material movement from causing cutting deviation or blade damage.

[0095] The blowing device 4 moves synchronously with the cutting wheel 30, and the blowing head 41 always points to the cutting area, blowing away high-temperature debris and heat in real time to avoid overheating and wear of the cutting wheel 30; the dust collection device 5 uses negative pressure to suck the debris generated by cutting from the dust collection trough 52 into the dust collection box 50, which reduces dust pollution and facilitates the recycling of debris; the folding door 14 achieves safe closure of the processing area 11 through the linkage of the spring lock structure 143 and the fixed switch mechanism 144. It can be folded and stored during maintenance, without taking up space, thus balancing operation safety and maintenance efficiency.
