Description

Technical Field

[0001] The utility model relates to a laser pipe cutting machine, in particular to a full-automatic feeding structure of the laser pipe cutting machine. Background Art

[0002] For the feeding machines of current pipe laser cutting equipment, there are problems such as single shape of the fed pipes, slow feeding speed, inaccurate positioning, manual turning of rectangular pipes, high labor intensity, low efficiency, and high labor costs. Therefore, a full-automatic feeding machine that can adapt to various shapes of pipes and has a fast feeding speed has been developed. For example, a side-hung full-automatic feeding laser pipe cutting machine with the patent application publication number CN117428353 A. However, during actual use, it is found that this feeding structure is more suitable for square-section square pipes and less suitable for rectangular-section square pipes (greatly affecting the cutting accuracy), resulting in a narrow applicable range. Because: as we know, the cross-section of square pipes has square and rectangular shapes. For square square pipes, since the width of each side is the same, the feeding before cutting is relatively simple and easy. For rectangular square pipes, due to the existence of wide and narrow sides, in order to facilitate clamping and positioning and ensure the cutting accuracy, they are usually unified into a lying flat state (i.e., the wide side is facing up) before cutting to make the placement of the pipes consistent before cutting. Currently, there is no full-automatic feeding mechanism on the market that is suitable for feeding rectangular square pipes with wide and narrow sides according to the unified wide side. Therefore, there is currently no truly full-automatic feeding structure that is suitable for pipes such as rectangular, square, and circular shapes, resulting in a narrow applicable range of such full-automatic feeding structures, and causing an increase in the use cost for pipe cutting manufacturers because they need to purchase multiple feeding devices to cut various pipes.

[0010] In the improvement scheme of the full-automatic feeding structure of the above laser tube cutting machine: the lifting plate actuator and the upper material pushing actuator adopt air cylinders.

[0011] In the improvement scheme of the full-automatic feeding structure of the above laser tube cutting machine: the material waiting baffle is swing-connected to the feeding rack, and the baffle release actuator is an air cylinder.

[0021] The present utility model relates to a full - automatic feeding structure of a laser pipe cutting machine. As shown Figures 1 to 5 , it includes a feeding part and a stockpiling part, where:

[0022] The feeding part includes a feeding rack 1 and multiple groups of feeding components 2 that are spaced on the feeding rack 1 and work synchronously; the feeding component 2 includes a sliding material support beam 21, a pushing area 22, a waiting area 23, and a preparation area 24; after the sliding material support beam 21 is inclinedly arranged on the feeding rack 1, the side close to the stockpiling part is higher; the pushing area 22, the waiting area 23, and the preparation area 24 are respectively arranged at the high, middle, and low positions of the sliding material support beam 21; in the pushing area 22, there are a pushing area detection device 221, a lower pushing plate 222, a lower pushing driving part 223, a vertical lifting plate 224 arranged on the lower pushing plate 222, a lifting plate driving part 225, and an upper pushing plate 226 and an upper pushing driving part 227 arranged on the vertical lifting plate 224; when the lower pushing plate 222, the vertical lifting plate 224, and the upper pushing plate 226 are in the reset state, the upper pushing plate 226 does not protrude (i.e., is not higher than) the sliding material support beam 21; in the waiting area 23, there are a waiting area detection device 231, a waiting material baffle 232, and a baffle release driving part 233; in the preparation area 24, there are a preparation area detection device 241, a preparation area baffle 242, and a lifting driving part (not shown in the figure). The sliding material support beam 21 is inclinedly arranged so that the pipes can automatically slide from the previous area to the next area by the gravity of the pipes without additional power for transportation. In this way, the feeding structure can be made simpler and the production cost can be lower.

[0023] The stockpiling part includes multiple L - shaped stockpiling racks 3 arranged at intervals, a lifting belt 4, a lifting belt lifting top part 5, and a lifting motor 6; the inner side of the stockpiling rack 3 is fixedly connected to the feeding rack 1; the lifting belt lifting top part 5 and the lifting motor 6 are arranged on the feeding rack 1; one end of the lifting belt 4 is fixed to the vertical rack of the stockpiling rack 3, and the middle part flexibly crosses the lifting belt lifting top part 5 and is then driven by the lifting motor 6 for winding and unwinding.

[0024] When the utility model is working, now taking the example of cutting rectangular pipes with different widths and lengths (as long as it can ensure that only one rectangular pipe can be pushed each time, other shapes of pipes such as square, circular, and elliptical can be easily realized):

[0025] Send the pipe to be cut in the stock area to the sliding material support beam 21: When the material pushing area detection device 221 detects that there is no pipe in the material pushing area 22, the lifting motor 6 starts to work to wind and tighten the lifting belt 4 to lift the pipe to be cut on the lifting belt 4, so that several pipes leaning against the sliding material support beam 21 slide to the higher part of the sliding material support beam 21 and are blocked by the rising lower material pushing plate 222 and the upper material pushing plate 226.

[0026] Next, the material pushing area 22 starts the material pushing work, aiming to keep only one pipe in the material pushing area 22: Since there may be more than one layer of pipes sliding down to the higher part of the sliding material support beam 21 and there may also be more than one pipe in the bottom layer, at this time, the upper material pushing driving part 227 and the lower material pushing driving part 223 in the material pushing area 22 need to work. Among them: After the upper material pushing driving part 227 drives the upper material pushing plate 226 to slide towards the stock rack 3, in addition to pushing the pipes in other layers except the bottom layer of pipes back onto the lifting belt 4, it can also push down the pipes placed sideways in the bottom layer and make them lie flat (that is, change from the narrow side facing up to the wide side facing up). As long as the height from the lowest end of the upper material pushing plate 226 after rising to the sliding material support beam 21 is set (either manually adjusted or set through the operating system of the pipe cutting machine) to be slightly higher than the width of the narrow side of the square pipe; After the lower material pushing driving part 223 drives the lower material pushing plate 222 to slide towards the stock rack 3, only one pipe is left on the top of the sliding material support beam 21 (by manual operation or setting the system of the laser pipe cutting machine, the distance from the front end of the lower material pushing plate 222 to the front end of the sliding material support beam 21 is made to be equivalent to the width of the wide side of the rectangular pipe), and after being detected and confirmed by the material pushing area detection device 221, the upper material pushing plate 226 retracts to its original position to complete the material pushing. For rectangular and elliptical pipes, they need to be pushed down and laid flat in the material pushing area by the upper material pushing plate 226, while for square and circular pipes, they do not need to be pushed down and laid flat.

[0027] Then, the waiting area detection device 231 detects whether there is a pipe in the waiting area 23. If not, the vertical lifting plate 224 in the material pushing area 22 descends and then returns to its original position. In this way, the only pipe in the material pushing area 22 will automatically slide into the waiting area 23 and be blocked by the waiting area baffle 232, so as to ensure that there is and only one pipe in the waiting area 23;

[0028] Next, the preparation area detection device 241 detects whether there is a pipe in the preparation area 24. If not, the baffle release driving part 233 will release the blocking of the pipe by the waiting area baffle 232. Then, the pipe in the waiting area 23 will automatically slide into the preparation area 24. In this way, it can also be ensured that there is and only one pipe in the preparation area 24.

[0029] After the cutting machine cuts one pipe, the lifting driving part will lift the pipe in the preparation area 24 and clamp it by the chuck of the pipe cutting machine, so that the laser pipe cutting machine can cut the next pipe.

[0030] Throughout the entire working process, always ensure that there is only one pipe in each area, preparing to continuously supply pipes to the corresponding next area or the laser pipe cutting machine.

[0031] As can be seen from the above, in addition to high automation, the utility model can also push the rectangular or oval pipes on the side into a lying flat state to ensure the consistency of the placement of the pipes before cutting, thereby ensuring the cutting accuracy and quality, etc. Therefore, the structure of the utility model is reasonable, with higher automation and a wider range of applicable occasions, and also reduces the production and use costs (due to reducing the purchase of various feeding mechanisms, etc.).

[0032] In this embodiment, the lower pusher 223 adopts a transmission structure of a gear 2231 and a rack 2232. After all the gears 2231 of the feeding assembly 2 are synchronously connected through a pusher linkage shaft 2233, they are driven by a pusher servo motor (not shown in the figure), as Figure 3 、 4 shown. In this way, it not only ensures the consistency of the lower pusher work but also reduces costs (sharing one servo motor).

[0033] Since the wear between the pipes sent from the stock part and the front end of the sliding material support beam is relatively large, for this reason, preferably, in this embodiment, as Figure 1 、 5 shown, the sliding material support beam 21 includes a front section support beam 211 located in the pusher area 22 and the remaining middle and rear section support beams 212; the front section support beam 211 is made of wear-resistant material for easy replacement, and a wear-resistant rubber pad (not shown in the figure) is provided on the surface of the front section support beam 211 to reduce the collision noise during work. The upper surface of the middle and rear section support beams 212 is in an arc shape to reduce friction.

[0034] The lifting plate pusher 225 and the upper pusher 227 adopt air cylinders, as Figures 1 to 4 shown.

[0035] The waiting material baffle 232 is swingably connected to the feeding rack 1, and the baffle release pusher 233 is an air cylinder, as Figure 4 shown.

[0036] The lifting motor 6 is a servo motor, the lifting belt 4 is connected to a winding disc 41, and all the winding discs 41 in the stock part are synchronously connected through a belt linkage shaft 42, as Figures 1 to 3 shown.

[0037] At present, various types of loading machines on the market have poor compatibility with pipes with lengths between 3.5 and 6.5 meters, high operating failure rates, or are simply unable to be compatible. To solve this pain point in the industry, in this embodiment, a movable auxiliary loading mechanism is added. For this purpose: an auxiliary feeding mechanism 8 is provided between two adjacent feeding components 2, which includes an auxiliary feeding frame 81 and an auxiliary sliding material supporting beam 82 provided on the auxiliary feeding frame 81; the auxiliary sliding material supporting beam 82 corresponds to the sliding material supporting beam 21 in terms of setting layout (such as setting height, inclination angle, etc.); on the feeding frame 1 located in the front part and / or rear part of the auxiliary feeding frame 81, an auxiliary frame moving guide shaft 83 is provided for guiding the movement of the auxiliary feeding frame 81; the auxiliary feeding frame 81 can move along the auxiliary frame moving guide shaft 83 and the linkage shaft 42. In this way, for pipes with different lengths, the auxiliary feeding frame can be moved to a suitable position to not only assist in feeding but also keep the pipe stable (because for some pipes, due to their length, their two ends cannot be exactly supported by the adjacent sliding material supporting beam. At this time, the auxiliary feeding frame can be moved to a suitable position to support the ends of the pipe to prevent the pipe from shaking due to the gravity of the ends and becoming unstable). Preferably, the auxiliary sliding material supporting beam 82 is also segmented like the sliding material supporting beam, and it includes a front-segment auxiliary supporting beam 821 and a middle-and-rear-segment auxiliary supporting beam 822.

[0038] In this embodiment, the pusher area detection device 221 is a photoelectric sensor, and the waiting area detection device 231 and the preparation area detection device 241 are pressure sensors.

[0039] In the description of the present invention, it should be understood that terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the conventional installation orientation of the product, or the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0040] Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present invention without departing from the principle and spirit scope of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention, and the scope of protection is defined by the content of the claims.
