Description

Technical Field

[0001] The invention relates to the field of laser tube cutting equipment, and in particular to a storage type three-chuck laser tube cutting machine. Background Art

[0002] The three-chuck laser tube cutting machine is a device with two front and rear pneumatic chucks and one middle electric chuck, and the three chucks cooperate with the laser tube cutting device to cut the tube. During operation, the three chucks can clamp the material at the same time and cooperate with the laser tube cutting device to cut, with the advantages of high precision, convenient operation, and easy maintenance.

[0003] However, when the material to be cut is a large-diameter pipe, it is difficult to load it automatically due to its large cross-sectional area, heavy weight, difficulty in stacking and storage, and difficulty in lifting. At present, large-diameter pipes are mostly loaded manually one by one, which is a heavy loading burden. Therefore, a storage-type three-chuck laser pipe cutting machine suitable for automatic loading of large-diameter pipes is needed to improve the above problems. Summary of the invention

[0004] In order to improve the problems in the background technology, the present invention provides a storage type three-chuck laser tube cutting machine, comprising a bed extending in the x-axis direction, the bed being provided with a laser tube cutting device and a chuck device; the chuck device comprising three coaxial chuck mechanisms, the three chuck mechanisms being connected to the bed through chuck guide rails extending in the x-axis direction; the bed being further provided with a feeding device, a long material collecting device, and a short material collecting device, the feeding device and the long material collecting device being respectively located on both sides of the laser tube cutting device; the short material collecting device being located between the long material collecting device and the laser tube cutting device;

[0005] The feeding device comprises at least three feeding mechanisms evenly spaced along the x-direction, the feeding mechanism comprising a first base frame, the length direction of the first base frame is parallel to the y-axis direction and its end is fixedly connected to the bed; the first base frame is divided into a feeding storage unit and a feeding conveying unit along its length direction, and the feeding conveying unit is close to the bed; the top of the feeding storage unit is penetrated by an inclined bottom groove I for placing materials along the x-axis direction, and the bottom surface of the inclined bottom groove I is higher than the end close to the feeding conveying unit at one end away from the feeding conveying unit; a limit block is provided at the end of the inclined bottom groove I close to the feeding conveying unit; the first base frame is arranged along the x-axis direction Material transfer plates are respectively arranged on two opposite side surfaces, the two material transfer plates correspond to each other, and the material transfer plates span the connection between the loading storage unit and the loading conveying unit along the length direction thereof; the material transfer plates include a lifting plate and an energy dissipation plate; the lifting plate is connected to the first base frame through a No. 1 lifting cylinder, the top surface of the lifting plate is parallel to the bottom surface of the inclined bottom groove I, and one end of the lifting plate extends to the side of the inclined bottom groove I along the length direction thereof; the energy dissipation plate is connected to the first base frame through a No. 2 lifting cylinder, one end of the energy dissipation plate extends to the side of the loading conveying unit along the length direction thereof, and the energy dissipation plate is bent upward away from the end of the inclined bottom groove I;

[0006] A material leveling baffle is provided at one end of the feeding device close to the laser tube cutting device; the material leveling baffle is perpendicular to the x-axis direction and corresponds to each of the inclined bottom grooves I.

[0007] In order to solve the problem of difficulty in automatic loading of large-diameter pipes due to their large cross-sectional area, heavy weight, and difficulty in stacking and storage, the loading device of the laser pipe cutting machine provided by the present invention integrates storage, transmission and automatic loading functions. Before cutting the pipe, the large-diameter pipes are stored in the inclined bottom groove I so that each pipe is arranged in a single layer. The loading storage unit of the first base frame arranged at intervals provides support for the large-diameter pipes along their length direction. One end of the large-diameter pipe abuts against the flushing baffle, so that the end of the pipe abutting against the flushing baffle is flush; the lifting plate in the supporting assembly plate can lift the pipe. Due to the inclined setting of the lifting plate, the pipe can automatically roll down from the lifting plate to the top of the energy dissipation plate. After being blocked by the bent part of the energy dissipation plate, the pipe stops rolling; the No. 2 lifting cylinder lowers the energy dissipation plate to drive the pipe down, and the pipe is transferred to the loading and conveying unit.

[0008] The loading storage unit on the first base frame allows multiple large-diameter pipes to be cut to be placed in the inclined bottom trough I in advance, avoiding the sequential lifting and loading of individual pipes during the pipe cutting process; after the pipes are placed in the inclined bottom trough I, the inclined bottom trough I is slightly tilted downward in the direction of the loading conveying unit, so that the large-diameter pipes roll to the bottom of the inclined bottom trough I due to their own weight and are then lifted and transported to the loading conveying unit by the supporting plate to realize automatic loading; the above-mentioned loading storage unit, loading conveying unit and the transfer plate for realizing the transfer of pipes between the two cooperate with each other, which is conducive to the multi-tube storage and batch automatic loading of large-diameter pipes, can save loading costs and improve loading efficiency.

[0009] Preferably, the No. 1 lifting cylinder is connected to the first base frame through a material dividing guide rail, and the length direction of the material dividing guide rail is parallel to the bottom surface of the inclined bottom groove I; a screw is rotatably set at one end of the material dividing guide rail to adjust the length of the lifting plate corresponding to the inclined bottom groove I, and the end of the screw is fixedly connected to the side of the No. 1 lifting cylinder; the limit block is connected to the top of the side face of the inclined bottom groove I away from the middle plate, and the limit block and the middle plate constitute an intermediate transition piece, and the two ends of the intermediate transition piece along the y-axis direction extend to the side of the lifting plate and the side of the energy dissipation plate respectively.

[0010] By turning the screw, the No. 1 lifting cylinder slides along the material distribution guide rail, and the No. 1 lifting cylinder drives the lifting plate to move, and the length of the lifting plate corresponding to the inclined bottom groove I also changes accordingly. Adjust the position of the No. 1 lifting cylinder and the lifting plate so that the length of the lifting plate corresponding to the inclined bottom groove I in each feeding mechanism is equal to the diameter of the pipe. At this time, the No. 1 lifting cylinder is lifted, and the lifting plate just lifts a pipe and transfers it to the feeding conveying assembly. The setting of the material distribution guide rail is conducive to adjusting the position of the lifting plate so that it can be used for pipes of different diameters.

[0011] Preferably, the bottom surface of the inclined bottom groove I, the side surface of the limit block close to the inclined bottom groove I, the upper surface of the lifting plate, and the upper surface of the energy dissipation plate are all paved with a buffer layer I; and a wedge-shaped buffer pad I is provided at one end of the bottom surface of the inclined bottom groove I close to the limit block, and the wedge-shaped buffer pad I is used to reduce the inclination angle of the bottom surface of the inclined bottom groove I, and its inclination angle is not greater than the inclination angle of the bottom surface of the inclined bottom groove I.

[0012] The buffer layer I can alleviate the collision of the first base frame with the pipe during the loading process. The setting of the buffer pad I is conducive to preventing the inclination angle of the bottom surface of the inclined bottom trough I from being too large. When the pipe rolls to the bottom of the inclined bottom trough I, the impulse is too large, causing the pipe to collide and be damaged.

[0013] Preferably, the feeding conveying unit includes a No. 1 power shaft and two first conveying chains extending along the y-axis direction; the two ends of the No. 1 power shaft are respectively meshed and connected with the two first conveying chains through sprockets I; the No. 1 power shafts of two adjacent feeding mechanisms are transmission connected via a No. 1 linkage shaft; the No. 1 power shaft of one of the feeding mechanisms is transmission connected to the output end of the feeding drive motor; the first conveying chain extends below the center line of the three chuck mechanisms, and baffle members I are arranged on the first conveying chain in pairs along the length direction thereof, and a material transfer groove I for accommodating materials is formed between the two opposite baffle members I; the material transfer grooves I of the two first conveying chains correspond to each other, and the length of the material transfer groove I gradually increases from the bottom to the top along the y-axis direction.

[0014] Preferably, the loading mechanism also includes a first follower support assembly; the first follower support assembly is fixedly connected to a side of the bed body close to the loading and conveying unit, and the first follower support assembly includes a support seat and a lifting base I; the support seat and the lifting base I are distributed along the x-axis direction, the support seat is fixed to the bed body, and the lifting base I is connected to the support seat through a No. 3 lifting cylinder; a centering bracket is provided on the top of the lifting base I, and a centering recess for supporting materials is provided on the top of the centering bracket along the x-axis direction; the centering recess is a symmetrical structure along the y-axis direction; the inner bottom of the centering recess coincides with the center lines of the three chuck mechanisms in the y-axis direction.

[0015] In the first follower support assembly, a centering bracket is arranged on the lifting base Ⅰ. When the pipe is clamped and driven to the position below the center line of the chuck mechanism by the relatively arranged baffle member Ⅰ, the No. 3 lifting cylinder lifts the lifting base Ⅰ, and the centering bracket supports the pipe to leave the feeding conveying unit. The pipe rolls to the bottom of the centering recess in the centering bracket due to gravity, and the axis of the pipe coincides with the center line of the centering recess of the centering bracket in the y-axis direction, that is, the axis of the pipe coincides with the center line of the three chuck mechanisms in the y-axis direction; the No. 3 lifting cylinder continues to lift the lifting base Ⅰ until the axis of the pipe completely coincides with the center line of the three chuck mechanisms, so as to facilitate the chuck mechanism to clamp the large-diameter pipe.

[0016] Preferably, the first follower support assembly also includes a clamping and centering unit; the clamping and centering unit is arranged on a side of the lifting base I away from the support seat, and the clamping and centering unit is connected to the lifting base I through a No. 4 lifting cylinder; the clamping and centering unit includes two oppositely arranged clamps, and the center points of the two clamps coincide with the center line of the chuck mechanism in the y-axis direction; corresponding to the clamping and centering unit, a clamping support bracket is arranged on the top of the lifting base I; the clamping support bracket and the centering bracket form a certain angle around the y-axis direction, and the bottoms of the two are integrally formed and hinged to the lifting base I through a bracket rotating shaft I; the bracket rotating shaft I is parallel to the y-axis direction, and its rotation is controlled by a steering cylinder I, and the output end of the steering cylinder I is hinged to the clamping support bracket or the centering bracket.

[0017] The arrangement of the clamping and centering unit and the clamping support bracket enables the first follower support mechanism to take into account the loading of materials with non-circular structures. For example, when loading materials with square structures such as square tubes, channel steels, and angle steels, they cannot be centered using the centering recesses because their shapes are not easy to slide. Therefore, a clamping and centering unit is required to assist in the centering so that the center lines of the material and the chuck mechanism correspond. The lifting base I is then lifted by the third lifting cylinder so that the axis of the material completely coincides with the center line of the chuck mechanism.

[0018] By controlling the steering cylinder Ⅰ to change the orientation of the centering bracket and the clamping support bracket, and adjusting the No. 4 lifting cylinder to change the height of the clamping centering unit relative to the lifting base Ⅰ, the centering support mode of the first follower support assembly can be changed, taking into account the automatic loading requirements of both circular and non-circular materials.

[0019] Preferably, the long material collecting device comprises at least three unloading mechanisms evenly spaced along the x-direction, the unloading mechanism comprising a second follower support assembly and a second base frame; the length direction of the second base frame is parallel to the y-axis direction, and the second base frame is connected to the bed through the second follower support assembly;

[0020] The second follower support assembly includes a first distance-adjusting slide rail, a first sliding seat, and a lifting base II; the first distance-adjusting slide rail is distributed along the y-axis direction, and the two ends of the first distance-adjusting slide rail are respectively fixedly connected to the bed and the second base frame; the lifting base II is movably arranged on the first distance-adjusting slide rail through the first sliding seat, and the lifting base II is connected to the first sliding seat through a No. 5 lifting cylinder;

[0021] A No. 1 roller group and a No. 2 roller group are arranged on the top surface of the lifting base II, the No. 1 roller group includes two rollers I, and the two rollers I are in a V-shaped structure symmetrical along the y-axis direction; the No. 2 roller group includes a roller II, and the length direction of the roller II is parallel to the y-axis direction; the No. 1 roller group and the No. 2 roller group are rotatably arranged on the unloading roller frame, and the unloading roller frame is hinged to the top of the lifting base II through the bracket rotating shaft II, and the bracket rotating shaft II is parallel to the y-axis direction; a steering cylinder II is fixed on the lifting base II, and the output end of the steering cylinder II is hinged to the unloading roller frame.

[0022] The chuck structures selected in the three chuck mechanisms are different. The chuck volume of the front chuck mechanism on the unloading side is larger than that of the rear chuck mechanism on the loading side, so the space below the rear chuck mechanism on the unloading side is limited. The second base frame is far away from the bed and is not directly connected to the bed. Under the premise of not raising the chuck device as a whole, it avoids hindering the sliding of the front chuck mechanism along the chuck guide rail. The cut material is supported by the second follower support assembly, and the lifting base II of the second follower support assembly slides along the first adjustable distance slide rail to send the material to the second base frame. The No. 1 roller group on the unloading roller frame meets the need to support the tube material, while the No. 2 roller group meets the need to support the non-circular structure material. In particular, when the material is a pipe, in order to prevent the pipe from rolling and falling from the lifting base II, the steering cylinder II rotates the No. 1 roller group in the unloading roller frame to face upward, and the two rollers I in the No. 1 roller group are in a V-shaped structure to limit the rolling of the pipe.

[0023] Preferably, the second base frame is divided into a material unloading conveying unit and a long material storage unit along its length direction, and the long material storage unit is connected to the second follower support assembly through the material unloading conveying unit; the material unloading conveying unit includes a No. 2 power shaft and two second conveying chains extending along the y-axis direction, and the two ends of the No. 2 power shaft are respectively meshed and connected with the two second conveying chains through sprockets II; the No. 2 power shafts of two adjacent material unloading mechanisms are connected by transmission through a No. 2 linkage shaft; the No. 2 power shaft of one of the material unloading mechanisms is connected by transmission with a material unloading driving motor; baffle members II are provided on the second conveying chain in pairs along its length direction, and a material transfer groove II for accommodating materials is formed between the two opposite baffle members II; the material transfer grooves II of the two second conveying chains correspond to each other; the length of the material transfer groove II gradually increases from the bottom to the top along the y-axis direction.

[0024] Preferably, an inclined bottom trough II for placing materials is provided through the top of the long material storage unit along the x-axis direction, the end of the bottom surface of the inclined bottom trough II close to the unloading material conveying unit is higher than the end away from the unloading material conveying unit, and a limiting column is provided at the end of the inclined bottom trough II away from the unloading material conveying unit; the bottom surface of the inclined bottom trough II and the side surface of the limiting column close to the inclined bottom trough II are paved with a buffer layer II; and a wedge-shaped buffer pad II is provided at one end of the bottom surface of the inclined bottom trough II close to the limiting column, and the wedge-shaped buffer pad II is used to reduce the inclination angle of the bottom surface of the inclined bottom trough II, and its inclination angle is not greater than the inclination angle of the bottom surface of the inclined bottom trough II.

[0025] The bottom surface of the inclined bottom trough II near the unloading conveying unit is higher than the end away from the unloading conveying unit. The material is conveyed to the end of the chain by the second conveying chain of the unloading conveying unit and then enters the inclined bottom trough II. The material slides to the bottom along the inclined surface of the inclined bottom trough II and is stored in a single layer in the inclined bottom trough II. The long material storage unit, the unloading conveying unit, and the second follower support assembly cooperate with each other to take into account the unloading automation of round and non-round materials. The single-layer arrangement of materials prevents large-diameter pipes and other materials with large cross-sectional diameters from being squeezed and deformed during storage. At the same time, the setting of the buffer layer II and the buffer pad II can reduce the impulse of the material when it rolls down, avoiding collisions between materials and collision damage between materials and the base frame.

[0026] Preferably, the short material collection device includes a turning mechanism and a short material storage mechanism, the turning mechanism and the short material storage mechanism are arranged along the y-axis direction, and the turning mechanism is located between the short material storage mechanism and the bed; the turning mechanism includes a second sliding seat, a lifting base III, and a second distance-adjusting slide rail extending along the y-axis direction, the lifting base III is movably arranged on the second distance-adjusting slide rail through the second sliding seat, and the lifting base III is connected to the second sliding seat through a No. 6 lifting cylinder; a flat support plate is hinged on the top of the lifting base III, and the rotating axis of the flat support plate is parallel to the x-axis direction; a tilting cylinder is fixedly arranged on the lifting base III, and the output end of the tilting cylinder is hinged to the bottom surface of the flat support plate close to the bed; the end of the flat support plate is hinged with A lower flip plate, the rotating axis of the lower flip plate is parallel to the y-axis direction, and the bottom of the lower flip plate is hinged to the output end of the flip cylinder; the short material storage mechanism includes a third base frame and a discharge track extending along the y-axis; the bottom of the third base frame is provided with rollers corresponding to the discharge track, and the interior of the third base frame is provided with a short material storage space; the top surface of the third base frame is provided with a short material opening connected to the short material storage space, and the short material opening extends along the y-axis direction; the end of the top surface of the third base frame close to the flipping mechanism is inclined toward the flat support plate; the top surface of the third base frame is close to the side of the laser tube cutting device. A correction baffle is provided; a parking rod is provided on the side of the third base frame away from the flipping mechanism, and a socket corresponding to the parking rod is provided at the bottom of the discharge track.

[0027] The bed is provided with a long material collecting device and a short material collecting device. The long material collecting device is suitable for collecting materials with a length greater than 1.5m, while the short material collecting device can meet the collection of materials with a length not greater than 1.5m. In addition, the short material collecting device can also be used to distinguish waste materials. When the cut material is short, the short material collecting device is used to collect the material; when the short material is unloaded, the middle chuck mechanism located in the middle moves along the chuck guide rail until it reaches the position of the axis of the lower flap, and the lower flap is driven by the flap cylinder to flip down, and the lifting base III moves along the second adjustable distance slide rail with the second sliding seat to the bottom of the short material to receive the short material. After the short material falls on the flat support plate, the tilting cylinder drives the flat support plate to tilt toward the third base frame, and the short material falls into the top surface of the third base frame and falls into the short material storage space through the short material opening. The inclined part of the third base frame helps the short material to continue to slide for a distance, which is conducive to the short material automatically adjusting its direction to be parallel to the y-axis direction during the continued sliding process and then falling into the short material opening. The shorter the cut material is, the closer it tends to be to the laser tube cutting device when it falls. At the same time, the shorter the material is, the easier it is to deviate from the y-axis direction during the sliding process. Therefore, a correction baffle is set at the corresponding side end of the third material storage base frame to prevent the shorter material from sliding out of the short material storage mechanism from the side end of the third material storage base frame. When processing the end-of-cut waste, the output end of the flap cylinder extends to push the lower flap to be flush with the flat support plate, and the chuck mechanism moves along the chuck guide rail to the position of the end of the lower flap. The lifting base III moves along the second sliding seat along the second adjustable distance slide rail to the bottom of the waste to receive the waste. The cut end-of-cut waste falls on the lower flap, the output end of the flap cylinder shrinks, and the lower flap flips down again. The end-of-cut waste falls into the waste collection device below, and the middle chuck mechanism moves along the chuck guide rail until it reaches the position of the axis of the lower flap, and the cutting and collection of short materials begins. The collection of the short material collection device is conducive to the automatic unloading and storage of short materials with a length of no more than 1.5m after cutting, and at the same time provides convenience for the automatic distinction and processing of neat waste and short materials.

[0028] In summary, this application has the following beneficial effects:

[0029] 1. The design of the feeding part of the present invention allows multiple large-diameter pipes to be cut to be placed in the inclined bottom groove I in advance, avoiding the sequential lifting and feeding of individual pipes during the pipe cutting process; the feeding storage unit, the feeding conveying unit and the transfer assembly plate for realizing the transfer of pipes between the two cooperate with each other, which is conducive to the multi-tube storage and batch automatic feeding of large-diameter pipes, can save feeding costs and improve feeding efficiency.

[0030] 2. The feeding part of the present invention can take into account the feeding needs of materials with circular structures and materials with non-circular structures; the first follower support component is respectively designed with corresponding follower support modes and centering modes for materials with circular structures and materials with non-circular structures. Gravity is used to center the circular material, and clamping is used to center the non-circular material. The two modes are dedicated to the specific type, which is conducive to realizing standardized operation of materials with different structures during the feeding process, and further improving the efficiency of centering the material and the chuck mechanism.

[0031] 3. The unloading part of the present invention includes a long material collecting device and a short material collecting device, which are respectively suitable for materials of different lengths after being cut; wherein, the short material collecting device enables the short materials after being cut to fall into the short material storage space through the flipping of the flat support plate and the inclined end of the third base frame, thereby realizing automatic unloading and storage of short materials; accordingly, the long material collecting device is also provided with an inclined bottom trough II, and the long materials are transported to the long material storage assembly by the cooperation of the second follow-up support assembly and the unloading conveying unit, and the long materials fall into and are arranged in a single layer in the inclined bottom trough II, thereby realizing automatic collection and storage of long materials; the design of the entire unloading part device saves the labor cost of collecting materials after cutting.

[0032] 4. The short material collecting device of the material discharge part of the present invention is provided with a short material storage space. The short material collecting device can not only collect short materials with a length not exceeding 1.5 m, but also can conveniently distinguish short materials from neat waste materials.

[0033] 5. The second follow-up support assembly in the long material collection device of the present invention is designed with roller groups of different shapes for materials with circular structures and materials with non-circular structures, taking into full consideration the characteristic that materials with circular structures are easy to roll. In particular, the roller group supporting the circular pipe is designed to be a V-shaped structure, which avoids the problem of rolling down during the unloading process of the pipe.

[0062] The implementation principle of this embodiment is:

[0063] refer to Figure 9-10 , arrange the material 8 in a single layer in the inclined bottom groove I 411-11, and one end of the material 8 abuts against the material baffle 5 to achieve alignment; turn the hand-cranked screw to adjust the material distribution slide plate, so that the length of the lifting plate 411-21 corresponding to the inclined bottom groove I 411-11 is equal to the diameter of the material 8; the No. 1 lifting cylinder lifts the lifting plate 411-21, and the material 8 slides from the lifting plate 411-21 to the middle transition piece, and the material 8 is guided along the middle transition piece to the energy dissipation plate 411-23; the energy dissipation plate 411-2 3 descends until the material 8 falls into the material transfer groove Ⅰ formed by one pair of baffle members Ⅰ411-311 on the first conveying chain 411-31; the material 8 is conveyed by the first conveying chain 411-31 to the top of the first follower support assembly 412, and the No. 3 lifting cylinder lifts the lifting base Ⅰ412-2 and the clamping and centering unit 412-3, and at the same time, the No. 4 lifting cylinder drives the clamping and centering unit 412-3 to lift the material 8, and the material 8 leaves the first conveying chain 411-31.

[0064] If the material 8 is a circular pipe, the steering cylinder I will rotate the centering bracket 412-21 to an upward position, and the No. 4 lifting cylinder will drive the clamping centering unit 412-3 to fall until the pipe falls into the centering recess of the centering bracket 412-21 to achieve centering, and the No. 3 lifting cylinder will lift the lifting base I 412-2 until the axis of the pipe coincides with the center line of the three chuck mechanisms.

[0065] If the material 8 is a non-circular structure, the centering cylinder drives the two centering jaws to clamp the material 8. The material 8 is centered to the middle position of the two jaws. The steering cylinder I rotates the clamping support bracket 412-22 to an upward position. The No. 4 lifting cylinder drives the clamping centering unit 412-3 to fall until the material 8 falls on the clamping support bracket 412-22. The No. 3 lifting cylinder lifts the lifting base I 412-2 while the clamping support bracket 412-2 lifts the material 8 until its center line coincides with the center line of the three chuck mechanisms.

[0066] The rear chuck mechanism 31 moves forward along the chuck guide rail 11, and one end of the material 8 is clamped by the rear chuck mechanism 31. The rear chuck mechanism 31 pushes the material 8 forward until the other end of the material 8 passes through the light curtain position of the middle chuck mechanism 32. At this time, the system can automatically identify the front end position of the material 8, thereby judging the length of the pipe and performing flush cutting according to this parameter.

[0067] For the treatment of the waste material cut at the same end: the output end of the flap cylinder of the short material collection device 7 extends to push the lower flap 723 to be flush with the flat support plate 721, the middle chuck mechanism 32 moves along the chuck guide rail 11 to the position of the end of the lower flap 723, and the lifting base III moves along the second adjustable distance slide rail with the second sliding seat to the bottom of the waste material to receive the waste material. The cut waste material falls on the lower flap 723, the output end of the flap cylinder shrinks, the lower flap 723 flips down again, and the waste material falls into the waste collection device below.

[0068] For the collection of short materials not larger than 1.5m after cutting: the middle chuck mechanism 32 moves along the chuck guide rail 11 until it reaches the position of the axis of the lower flap 723, and the lower flap 723 is flipped downward by the flap cylinder, and the lifting base III 721 moves along the second distance adjustment slide rail with the second sliding seat to the bottom of the short materials to receive the short materials, and after the short materials fall on the flat support plate 721, the tilting cylinder 722 drives the flat support plate 721 to tilt toward the third base frame 711, and the short materials fall into the top surface of the third base frame 711, and fall into the short material storage space 711-2 through the short material opening 711-1. The tilted part of the third base frame 711 helps the short materials to continue to slide for a distance, which is conducive to the automatic adjustment of the direction of the short materials to be parallel to the y-axis direction during the continued sliding process and then fall into the short material opening 711-1. The shorter the material 8 being cut is, the closer the material 8 tends to be to the laser tube cutting device 2 when falling. At the same time, the shorter the length of the material 8 is, the easier it is for it to deviate from the y-axis direction during the sliding process. Therefore, a correcting baffle 711-3 is provided at the corresponding side end of the third material storage base, which can prevent the shorter material 8 from sliding out of the short material storage mechanism 71 from the side end of the third material storage base.

[0069] For the collection of long materials longer than 1.5m after cutting: when the material 8 is a circular pipe, the reversing cylinder II rotates the material unloading roller frame to turn the No. 1 roller group upward; when the material 8 is a non-circular structure, the steering cylinder II rotates the material unloading roller frame to turn the No. 2 roller group upward. The No. 5 lifting cylinder drives the lifting base II 611-3 to lift up to receive the material 8, and the first sliding seat 611-2 moves along the first sliding seat 611-2 to the end of the second conveying chain 612-11 under the control of the motor; the No. 5 lifting cylinder drives the lifting base II 611-3 to descend, and the material 8 falls into the material transfer groove II and is finally sent to the inclined bottom groove II 612-21 by the second conveying chain 612-11 to realize the storage of the unloaded material.

[0070] 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.
