Detailed Implementation

[0024] This utility model provides a horizontal automatic material receiving and pipe cutting machine. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0025] Please see Figures 1-3This utility model provides a horizontal automatic material receiving and cutting pipe machine, including a bed 1, a front chuck structure 2 and a gantry frame 11 disposed at the front end of the bed 1, a laser cutting assembly 12 disposed on the gantry frame 11, a rear chuck structure 3 that can reciprocate along the length direction of the bed 1, and a variable diameter wheel support mechanism 4 disposed in the bed 1. The front end of the bed 1 is also provided with a material receiving mounting frame 13 and a material receiving mechanism 6 disposed on the side wall of the material receiving mounting frame 13. The material receiving mechanism 6 includes a material receiving lifting frame 61, a material receiving rack 62 vertically disposed on the material receiving lifting frame 61, a material receiving gear 63 meshing with the material receiving rack 62, a material receiving lifting drive component that is pulsatically connected to the material receiving gear 63, a material receiving plate 66 whose end face is rotatably connected to the side wall of the material receiving lifting frame 61, and a material receiving cylinder 67 fixedly connected to the side wall of the material receiving mounting frame 13 and used to drive the material receiving plate 66 to tilt horizontally or downward.

[0026] In practical applications, the pipe to be processed is loaded, and the rear chuck structure 3 moves towards the front chuck structure 2. The front chuck structure 2 and the rear chuck structure 3 clamp the pipe. The variable diameter wheel support mechanism 4 in the bed 1 supports the middle of the pipe, preventing bending in the middle during cutting and ensuring the straightness of the pipe, thus improving cutting accuracy. The rear chuck structure 3 pushes the pipe towards the front chuck structure 2, and the laser cutting assembly 12 performs laser processing on the pipe. The processed pipe is located above the receiving mechanism 6. During pipe cutting, the receiving lifting drive unit rotates the receiving gear 63, causing the receiving lifting frame 61, which is fixedly connected to the receiving rack 62, to rise or fall. This adjusts the height of the receiving plate 66 to suit the pipe's height. During cutting, especially towards the end of the pipe, the pipe's weight can cause stretching and bending deformation. Adjusting the height of the receiving plate 66 ensures it supports the pipe, maintaining its straightness and improving cutting accuracy. After the cut pipe falls onto the receiving plate 66, the retraction of the receiving cylinder 67 causes the end of the receiving plate 66 to tilt downwards around the side wall of the receiving lifting frame 61, guiding the unloading of the pipe.

[0027] The aforementioned pipe cutting machine, by adding an adjustable height receiving lifting frame 61 and a receiving plate 66 to the existing pipe cutting machine, and the receiving plate 66 being horizontal and tiltable, adapts to the support, receiving and unloading of pipes during cutting, ensuring the straightness of the pipes and improving the pipe cutting accuracy.

[0028] Please see Figure 2In some embodiments, the receiving lifting drive includes a reducer 64 and a handwheel 65 connected to the input end of the reducer 64, with the receiving gear 63 located at the output end of the reducer 64. In practical use, rotating the handwheel 65 drives the receiving gear 63 to rotate, thereby raising or lowering the components on the receiving lifting frame 61. After adjusting the height of the receiving plate 66, the handwheel 65 is locked to ensure that the receiving plate 66 remains at a suitable height during pipe cutting. Compared to using a drive motor as the driving source, the handwheel 65 is more energy-efficient and has lower manufacturing costs.

[0029] Please see Figure 2 In some embodiments, the side wall of the receiving mounting frame 13 is further provided with a drive component mounting plate, and the receiving lifting frame 61 is provided with a vertically extending receiving guide rail 68. The receiving guide rail 68 is provided with a receiving slider 69, and the receiving slider 69 is fixedly connected to the drive component mounting plate. The receiving guide rail 68 and the receiving slider 69 are configured to guide the smooth rise or fall of the receiving lifting frame 61, so as to avoid the receiving lifting frame 61 and the receiving plate 66 from shaking.

[0030] Please see Figure 4 In some embodiments, the variable diameter wheel support mechanism 4 includes a support mounting plate 41 disposed in the bed 1, a support cylinder 42 with its cylinder body disposed on the support mounting plate 41 and its output end facing upward, a support lifting frame 43 disposed on the output end of the support cylinder 42, a variable diameter support wheel 44 rotatably connected to the support lifting frame 43, and a pin 45 disposed on the support lifting frame 43; the end face of the variable diameter support wheel 44 is provided with a plurality of positioning holes 441 distributed along the circumference, and the pin 45 is used to insert into any of the positioning holes 441. The middle part of the variable diameter support wheel 44 is provided with an arc groove 442 along the circumference, and the opening of the arc groove 442 is gradually set from small to large along the circumference. Therefore, the variable diameter support wheel 44 can be rotated to face upward according to the diameter of the pipe to be processed, and then the pin 45 is inserted into the corresponding positioning hole 441 to fix the variable diameter support wheel 44. After the adjustment of the variable diameter support roller 44 is completed, the extension or retraction of the output end of the support cylinder 42 is used to realize the variable diameter support roller 44 to support the pipe.

[0031] Specifically, two variable diameter wheel support mechanisms 4 are provided along the length of the bed 1.

[0032] Please see Figure 4In some embodiments, a support guide sleeve 46 is provided on the support mounting plate 41, and a vertically extending support guide rod 47 is slidably disposed in the support guide sleeve 46. The upper end face of the support guide rod 47 is fixedly connected to the lower surface of the support lifting frame 43. When the length of the pipe is long, the weight of the pipe exerts a large pressure on the reducing roller 44. The support guide sleeve 46 and the support guide rod 47 can improve the stability of the support cylinder 42 during operation.

[0033] Please see Figure 4 In some embodiments, the upper surface of the support mounting plate 41 is further provided with a support buffer rubber 48, which is used to prevent the support lifting frame 43 from colliding with the support mounting plate 41. When the support cylinder 42 malfunctions and the support lifting frame 43 suddenly loses its upward support force, it will suddenly fall. Therefore, the support buffer rubber 48 is provided between the support lifting frame 43 and the support mounting plate 41 to prevent the support lifting frame 43 from falling and causing excessive impact force to affect the mechanism, and also to avoid generating excessive noise.

[0034] Please see Figure 5 In some embodiments, the bed 1 is further provided with a clamping mechanism 5 for supporting and clamping the pipe; the clamping mechanism 5 includes a clamping mounting frame 51, a lifting cylinder 52 disposed on the side wall of the clamping mounting frame 51 with its output end facing upward, a clamping lifting frame 53 disposed on the output end of the lifting cylinder 52, a clamping cylinder 54 disposed on the side wall of the clamping lifting frame 53 with its output end facing upward, a pull block 55 disposed on the output end of the clamping cylinder 54, and a pull rod 56 with one end rotatably connected to the pull block 55 and the other end rotatably connected to the clamping block 57; the pull rod 56 and the clamping block 57 are symmetrically arranged along the vertical line of the clamping cylinder 54, and a gap for clamping the pipe is formed between the two clamping blocks 57. When loading is required, the lifting cylinder 52 drives the clamping lifting frame 53 to rise, and the upper surface of the clamping lifting frame 53 contacts the lower end face of the pipe. The clamping cylinder 54 operates, pulling the two levers 56, causing the two clamping blocks 57 to move closer together and clamp the pipe, making the pipe concentric with the front chuck structure 2 and the rear chuck structure 3. The front chuck structure 2 and the rear chuck structure 3 can then be used to clamp and position the pipe. When cutting the pipe, the extension or retraction of the output end of the lifting cylinder 52 and the output end of the clamping cylinder 54 enables the pipe to be supported vertically and horizontally. This function of supporting vertically and horizontally is suitable for processing non-circular pipes.

[0035] Specifically, two clamping mechanisms 5 are provided along the length of the bed 1.

[0036] Please see Figure 5In some embodiments, the clamping lifting frame 53 has two clamping guide rails 581 parallel to the moving direction of the pull rod 56 on its side wall facing the pull block 55. Each of the two clamping blocks 57 has a clamping slider 582 on its side wall facing the clamping lifting frame 53, and the clamping slider 582 is slidably mounted on the corresponding clamping guide rail 581. The clamping guide rails 581 and clamping sliders 582 provide guidance for the movement of the clamping blocks 57, allowing the clamping cylinder 54 to smoothly move the two clamping blocks 57 on the clamping guide rails 581 by pulling the two pull rods 56.

[0037] Please see Figure 5 In some embodiments, the clamp mounting bracket 51 is provided with a clamp guide sleeve 591, and a vertically extending clamp guide rod 592 is slidably disposed in the clamp guide sleeve 591. The upper end face of the clamp guide rod 592 is fixedly connected to the lower surface of the clamp lifting frame 53. Similarly, the clamp guide sleeve 591 and the clamp guide rod 592 are used to improve the stability of the clamping mechanism 5 during operation.

[0038] Please see Figure 3 In some embodiments, anti-collision rubber 14 is provided at the front and rear ends of the bed 1, and the rear chuck structure 3 reciprocates between the two anti-collision rubber 14. When the drive component on the rear chuck structure 3 malfunctions, the anti-collision rubber 14 can prevent the rear chuck structure 3 from colliding with the front chuck structure 2, and can also prevent the rear chuck structure 3 from continuously moving backward.

[0039] In summary, this utility model adds an adjustable height receiving lifting frame 61 and a receiving plate 66 to the existing pipe cutting machine. The receiving plate 66 can be horizontal or tilted, thus adapting to the support, receiving and unloading of pipes during cutting, ensuring the straightness of the pipes and improving the pipe cutting accuracy.
