Description

Technical Field

[0001] The present application relates to the technical field of pipe cutting equipment, and in particular to a side-mounted three-chuck pipe cutting machine. Background Art

[0002] To meet the needs of modern industrial production, the emergence of laser tube cutting machines has greatly shortened the production cycle of tube and plate cutting. It is widely used in industries such as automobile manufacturing, machinery manufacturing, and tube processing.

[0003] Related technology can refer to the Chinese patent application with announcement number CN115647612A, which discloses a side-mounted three-chuck pipe cutting machine and a working method, including a bed assembly, a gantry assembly, a front chuck assembly, a middle chuck assembly, and a rear chuck assembly; a material receiving assembly is arranged between the front chuck assembly and the middle chuck assembly, and the material receiving assembly includes a material receiving base installed on the side of the bed and on the same side as the three chucks, and the material receiving base is provided with slide rails parallel to each other, and a material receiving horizontal slide is slidably installed on the slide rails. A material receiving translation motor is fixedly installed at the bottom, which is connected to the material receiving translation screw by transmission. The bottom of the material receiving horizontal slide is threadedly connected to the bottom of the material receiving translation screw. A material receiving lifting motor and a material receiving lifting reducer connected to the material receiving lifting motor are fixedly installed on the upper part of the material receiving horizontal slide. A material receiving lifting slide plate is slidingly installed on the side of the material receiving horizontal slide. The material receiving lifting reducer is connected to the material receiving lifting slide plate through a gear rack pair, and the rotation of the material receiving lifting reducer causes the material receiving lifting slide plate to slide up and down. A flat support plate is hinged on the material receiving lifting slide plate, and a side-turning cylinder for side-turning the flat support plate is hinged at the lower end of the material receiving lifting slide plate. The piston rod of the side-turning cylinder is hinged to the flat support plate, and the base of the side-turning cylinder is fixed on the material receiving lifting slide plate.

[0004] With regard to the above-mentioned related technologies, the material receiving lifting motor drives the material receiving lifting slide plate to slide up and down through the gear rack structure, thereby driving the flat pallet to rise and fall. Therefore, while meeting the installation requirements of the three chucks, the overall height of the cutting machine needs to be designed according to the height of the flat pallet at the lowest point. When the flat pallet is folded, it is at the lowest point, and the distance from the flat pallet to the lower end surface of the material receiving base is at least the sum of the heights of the material receiving base and the material receiving horizontal slide. When the flat pallet is raised to the highest point, the distance between the flat pallet and the lower end surface of the material receiving base is at least the height of two lifting slide plates. The lifting of the flat pallet is a one-stage lifting, and the lifting height is limited. It is difficult to fold it to a sufficiently low position when folded. Therefore, the overall height of the cutting machine needs to be increased, resulting in higher material costs. Summary of the invention

[0009] By adopting the above technical solution, the bottom plate moves upward to lift the pipe delivered by the loader upward. The pipe is located between the two slides. The driving device is used to drive the two slides to move in opposite directions to clamp the pipe, thereby achieving the centering positioning of the feeding pipe and improving the feeding accuracy and stability.

[0010] Optionally, the driving device includes a driving cylinder, a steel wire and two rotating wheels. The driving cylinder and the rotating wheel are both located on a side of the base plate close to the loader and the driving cylinder body is fixedly connected to the base plate. The telescopic shaft end of the cylinder is fixedly connected to a slide plate. The rotating wheel is rotatably connected to the base plate along its own axis. The axis of the rotating wheel extends in a horizontal direction and is perpendicular to the sliding direction of the slide plate. The steel wire is used to connect the two rotating wheels. Two pulling ear seats are fixedly provided on the steel wire. The two pulling ear seats are respectively located on the upper and lower sides of the rotating wheel, and the two pulling ear seats are respectively fixedly connected to the two slides.

[0011] By adopting the above technical solution, when the driving cylinder is started, its telescopic shaft pushes one of the slides to slide in the horizontal direction, and the slide drives the pull ear seat fixedly connected thereto to move, and the pull ear seat is fixedly connected to the steel wire. Due to the cooperation between the steel wire and the two rotating wheels, the two pull ear seats move along the rotation track of the steel wire. The two pull ear seats are located on the upper and lower sides of the rotating wheel, so that the two pull ear seats move in opposite directions in the horizontal direction, so that the two slides connected to different pull ear seats slide in opposite directions, and then drive the two slides away from each other to loosen the material. On the contrary, when the telescopic shaft of the driving cylinder is retracted, the two slides approach each other, so that the material can be clamped accurately, and the whole process is stable and reliable, which is convenient for automatic operation.

[0012] Optionally, a roller seat is provided on the side of the base plate away from the loader, and a plurality of rollers are rotatably connected to the upper end surface of the roller seat. The axial direction of the rollers is the same as the sliding direction of the slide plate, and the rollers are higher than the upper end surface of the base plate in the vertical direction. A first lifting cylinder is fixedly provided on the side wall of the loading lifting frame, and the telescopic shaft end of the first lifting cylinder is fixedly connected to the roller seat. A guide shaft is fixed to the lower end of the roller seat, and the guide shaft is slidably connected to the loading lifting frame along the vertical direction.

[0013] By adopting the above technical solution, the telescopic shaft of the first lifting cylinder extends upward, driving the roller seat to rise, so that the roller abuts against the pipe on the feeder, and then drives the pipe to rise and center the pipe. After the front chuck clamps the pipe, it pushes the pipe into the middle chuck. The pipe can move smoothly along the roller during the conveying process, improving the conveying efficiency. The first lifting cylinder drives the roller seat to slide up and down, realizing flexible adjustment of the workpiece height to meet the feeding requirements of different heights.

The side wall of the clamping roller is located between the two vertical plates. The highest ends of the slide plate, the vertical plate and the clamping roller are not higher than the highest end of the base plate in the vertical direction.

At the same time, the unloading lifting frame and the follow-up centering component are both in the initial unlifted state, so that the height of the feeder is adapted to the height of the follow-up centering component at this time, reducing the height of the feeder and saving production material costs. After the two clamping rollers clamp the pipe in the center, the front chuck pushes the pipe into the middle chuck. The clamping rollers always clamp the pipe during the transportation process, and the movement of the pipe drives the clamping rollers to rotate, thereby improving the stability of the pipe during the transportation process.

[0016] Optionally, the unloading and flipping assembly includes a flipping bracket, a flipping cylinder and a bracket. The flipping bracket is located on a side of the unloading lifting frame away from the rear bed and is slidingly connected to the unloading lifting frame in the vertical direction. The bracket is located above the unloading main frame, the unloading lifting frame and the flipping bracket.

[0017] By adopting the above technical solution, the telescopic shaft of the third lifting cylinder drives the flip bracket to rise and fall, thereby driving the bracket to rise and fall. When cutting the pipe, the bracket supports the pipe. For round pipes, the bracket is raised and lowered to adapt to pipes of different diameters; for non-round pipes, the height of the bracket is adjusted in real time as the pipe rotates to adapt to the pipe, so that the bracket always supports the pipe. The flipping cylinder drives the bracket to rotate, and the cut pipe is flipped by the bracket and separated from the blanking flipping component under the action of the pipe's own gravity. Ensure a smooth transition of pipe fittings during cutting and blanking, reduce the risk of pipe fittings offset or falling during cutting and blanking, and improve blanking efficiency and safety.

The provided guard plate guides the dropped pipe to ensure that the pipe falls into the material cart. At the same time, the material cart can also collect waste chips generated during cutting.

The bottom plate moves upward to lift the pipes conveyed by the feeder upward. The pipes are located between the two slides. The drive device drives the two slides to move in the opposite direction to clamp the pipes, so as to achieve the centering positioning of the feeding pipes and improve the feeding accuracy and stability. 3. When the driving cylinder is started, its telescopic shaft pushes one of the slides to slide in the horizontal direction, and the slide drives the pull ear seat fixedly connected to it to move.

The unloading lifting frame 22 can slide up and down on the slide rail of the unloading main frame 21, and realizes a smooth lifting action through the lead screw. The flip assembly is slidably connected to the unloading main frame 21 in the vertical direction, and the height adjustment is realized through the third lifting cylinder 221. The flip cylinder 232 on the bracket 233 drives the bracket 233 to flip, which is convenient for placing and unloading materials.

[0050] A trolley 9 with an upper opening is provided on the side of the middle chuck 7 close to the material feeder follower 2, a pull rod 91 is provided on the side of the trolley 9 away from the rear bed 5, and a guard plate 51 is provided on the side of the rear bed 5 close to the trolley 9. The side of the guard plate 51 close to the trolley 9 gradually moves away from the rear bed 5 from the upper end to the lower end, and the lower end of the guard plate 51 is located above the opening of the trolley 9. When the length of the cut pipe is short and not enough to extend to the first material feeder flip assembly 23 close to the middle chuck 7, or the length falling on the material feeder flip assembly 23 is less than the length not on the material feeder flip assembly 23, the pipe dropped after cutting falls into the trolley 9, and the pull rod 91 is provided to facilitate the operator to pull the trolley 9. The guard plate 51 guides the dropped pipe to ensure that the pipe falls into the trolley 9. At the same time, the trolley 9 can also collect waste chips generated during cutting.

[0051] The specific implementation process of this equipment is: first, use the lifting equipment to place the pipe on the end of the feeder 3 away from the front bed 4, and all the feeders 3 work synchronously to transport the pipe. When the pipe reaches the top of the feeding follower mechanism 1, the follower centering component 13 moves upward, and the two clamping rollers 135 slide towards each other to clamp the pipe so that the pipe is in the middle position. The feeding lifting frame 12 drives the follower centering component 13 to slide upward together, and the front chuck 6 moves toward the pipe on the front bed 4. After the front chuck 6 clamps one end of the pipe, the front chuck 6 drives the pipe to move toward the middle chuck 7. As the front chuck 6 moves, the feeding follower mechanism 1 on the path returns to the lowest state in turn to avoid the movement of the front chuck 6. After the pipe extends into the middle chuck 7 and reaches the cutting length requirement, the middle chuck 7 clamps the pipe, and the end of the pipe away from the front chuck 6 is clamped by the rear chuck 8, and the cutting device is used to cut the pipe. When the length of the cut pipe is short and has not reached the first feeding follower mechanism 2 or a small part is located above a feeding follower mechanism 2, it is directly cut and the cut pipe falls directly into the material cart 9; if the length of the cut pipe is long, the feeding follower mechanism 2 is lifted upward so that the roller 235 abuts against the lower end of the pipe. After the cutting is completed, the rear chuck 8 drives the pipe away from the middle chuck 7, and then the rear chuck 8 is released, and the flip cylinder 232 drives the support plate 234 to flip and unload the pipe. The feeding follower mechanism 1 and the feeding follower mechanism 2 support the pipe. At the same time, if it is not a round pipe, the middle chuck 7 will rotate when cutting after clamping the pipe. When the pipe rotates, the height of the follower centering component 13 and the flipping component is controlled and adjusted so that the roller 141 and the roller 235 abut against the pipe at any time. Ensure the smooth transition of the pipe fittings during the cutting and feeding process, reduce the risk of the pipe fittings being offset or falling during the cutting and feeding process, and improve the feeding efficiency and safety.

[0052] The implementation principle of a side-mounted three-chuck pipe cutting machine in an embodiment of the present application is as follows: a loading lifting frame 12 is slidably connected to a loading main frame 11, a follower centering assembly 13 is slidably connected to the loading lifting frame 12, a unloading lifting frame 22 is slidably connected to the unloading main frame 21, a unloading flipping assembly 23 is slidably connected to the unloading lifting frame 22, a loading follower mechanism 1 and a unloading follower mechanism 2 realize multi-stage lifting, when the loading follower mechanism 1 is fully retracted and in the lowest state, it is located below the front chuck 6, and when the unloading follower mechanism 2 is fully retracted and in the lowest state, it is located below the rear chuck 8, thereby reducing its own installation height, thereby reducing the height of the middle chuck 7 and the bed, reducing the height of the overall pipe cutting machine, reducing the materials required for the production equipment, and reducing the production cost. The follow-up centering component 13 can automatically center and clamp the pipe during the loading process, so that the front chuck 6 clamps the pipe and pushes it into the middle chuck 7 to ensure the loading accuracy; the unloading and flipping component 23 can slide up and down to adapt to pipes of different sizes, improve the stability of the pipe during cutting, and improve the cutting accuracy; at the same time, the unloading and flipping component 23 can flip and take over the processed pipe, reduce manual intervention, and improve production efficiency.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
