[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] Laser tube cutting machines are industrial machinery that utilize lasers for cutting. They are specifically designed to cut pipes, tubes, or long strips of material to meet specific manufacturing, construction, or processing needs. The main function of these machines is to cut long strips of material into the required length, usually in a highly precise and efficient manner. They are widely used in the industrial and manufacturing fields.

[0004] At present, when using a laser tube cutting machine to cut tubes or profiles, manual auxiliary loading is required. The tubes or profiles are placed on a feeding device in the form of a conveyor belt by manpower or with the help of a sling. The tubes or profiles to be cut are transported into the laser tube cutting machine in sequence using the above-mentioned feeding device for cutting. The labor intensity of the operator is high, the production efficiency is low, and the positioning accuracy is relatively low. In addition, the above-mentioned feeding device can only realize the feeding operation of a single type of tube or profile, and cannot perform feeding operations on tubes or profiles with different cross-sectional shapes, and has poor applicability. Therefore, it is urgent to design an auxiliary feeding device for the laser tube cutting machine to solve the above problems. Utility Model Content

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail:

[0020] See Figure 1 The auxiliary loading device of the laser tube cutting machine of the present invention includes a storage rack structure 5 for storing tubes. A feeder bracket 2 is mounted on the storage rack structure 5. Multiple sets of equally spaced pipe-limiting assemblies 6 are mounted on the feeder bracket 2 to arrange the tubes in a single layer. Multiple sets of laterally adjustable pipe-lifting assemblies 3 are also mounted on the storage rack structure 5 to lift the lowest tube and push it out of the storage rack structure 5.

[0021] like Figure 2 As shown, the storage rack structure 5 includes a storage rack body 5-4, on which a plurality of groups of pipe-holding rods 5-2 are fixedly connected and distributed in parallel in a transverse direction. The pipe-holding rods 5-2 are tilted from top to bottom toward the direction gradually approaching the feeding bracket 2. The storage rack structure 5 also includes a pipe-blocking upright 5-3 installed on the storage rack body 5-4 and located at the lower end of the pipe-holding rod 5-2. The top of the pipe-blocking upright 5-3 is higher than the lower end of the pipe-holding rod 5-2 and is used to block the pipes. The storage rack structure 5 also includes a transition guide block 5-1 installed on each transition guide block 5-1 for guiding the pipes pushed out by the pipe lifting assembly 3. The transition guide block 5-1 has a triangular structure.

[0022] like Figure 2As shown, the aforementioned position-limiting pipe assembly 6 includes a position-limiting arm 6-1 fixed to the feed bracket 2. A longitudinally adjustable pipe retaining plate 6-2 is mounted on the position-limiting arm 6-1. The pipe retaining plate 6-2 has longitudinally extending strip holes formed therein. The pipe retaining plate 6-2 is connected to the position-limiting arm 6-1 via screws inserted through the strip holes. A guide slope 6-3 is provided on the pipe retaining plate 6-2, which slopes upward from bottom to top toward the storage rack structure 5.

[0023] like Figure 2 As shown, the above-mentioned pipe lifting assembly 3 includes a distance-adjusting mounting seat 3-4 fixedly connected to the storage rack structure 5, and a horizontally arranged distance-adjusting screw 3-1 is rotatably connected to the distance-adjusting mounting seat 3-4. The extension direction of the distance-adjusting screw 3-1 is perpendicular to the axial direction of the pipes placed on the storage rack structure 5. The pipe lifting assembly 3 also includes a movable cylinder seat 3-2 connected to the distance-adjusting screw 3-1 through a nut, and a longitudinally arranged lifting cylinder 3-3 is fixedly connected to the movable cylinder seat 3-2. A lifting wedge block 3-5 is installed at the protruding end of the lifting cylinder 3-3. The top surface of the lifting wedge block 3-5 is an inclined surface, and the inclined surface is inclined from bottom to top toward the direction gradually approaching the storage rack structure 5. In addition, for convenient operation, a handwheel is installed at the outer end of the distance-adjusting screw 3-1.

[0024] like Figure 1 As shown, this embodiment further includes a feeding support assembly 4 installed on the feeding bracket 2, which is used to receive the pipes pushed out by the multiple pipe lifting assemblies 3. Figure 3 The feed support assembly 4 includes multiple sets of lifting roller seats 4-5 movably mounted on the feed bracket 2. Each lifting roller seat 4-5 is rotatably connected to two sets of feed rollers 4-6, which are arranged in a V-shaped configuration. The assembly also includes a rack lifting mechanism for driving the lifting roller seats 4-5 to move synchronously. The lifting roller seats 4-5 are evenly distributed along the axial direction of the pipe.

[0025] like Figure 3As shown, the rack lifting mechanism includes multiple sets of feed supports 4-9 fixedly connected to the feed bracket 2 and arranged in a horizontal parallel arrangement. A transverse feed shaft 4-1 is rotatably connected between the multiple sets of feed supports 4-9. The feed shaft 4-1 is rotatably connected to each feed support 4-9 via a seat bearing. A rack guide seat 4-8 is fixedly connected to each feed support 4-9. A cylindrical rack 4-7 is inserted into each rack guide seat 4-8 and slidably connected thereto. Multiple sets of lifting roller seats 4-5 are mounted one on top of each set of cylindrical racks 4-7. The rack lifting mechanism also includes multiple sets of lifting gears 4-3 keyed to the feed shaft 4-1, each of which meshes with the multiple sets of cylindrical racks 4-7. It also includes a lifting operating wheel 4-10 keyed to the end of the feed shaft 4-1. A notch is provided on each rack guide seat 4-8 for exposing part of the teeth of the cylindrical rack 4-7.

[0026] In the actual working process, the rotation of the above-mentioned feeding horizontal shaft 4-1 can drive the lifting gear 4-3 connected to the key thereon to rotate. Since the lifting gear 4-3 and the cylindrical rack 4-7 are engaged, the rotating lifting gear 4-3 can drive the cylindrical rack 4-7 to move up and down, and then drive the lifting roller seat 4-5 and the two sets of feeding rollers 4-6 installed on the lifting roller seat 4-5 to move up and down synchronously.

[0027] like Figure 1 As shown, this embodiment further includes a clamping feeding assembly 1 installed at the end of the feeding bracket 2, which is used to clamp the pipe supported by the feeding support assembly 4 and drive the pipe to move a predetermined distance toward the cutting head.

[0028] See further Figure 4 The above-mentioned clamping and feeding assembly 1 includes a feeding mounting seat 1-1 fixedly connected to the feeding bracket 2, a clamping movable seat 1-4 is movably mounted on the feeding mounting seat 1-1, a clamping claw cylinder 1-5 is fixedly connected to the clamping movable seat 1-4, and two sets of clamping blocks 1-6 arranged oppositely are mounted on the clamping claw cylinder 1-5 for clamping pipe fittings; and also includes a screw drive mechanism for driving the clamping movable seat 1-4 to move horizontally.

[0029] The screw drive mechanism includes multiple groups of feed guide rails 1-7 fixed on the feed mounting seat 1-1, the extension direction of the feed guide rails 1-7 is consistent with the axis of the pipe supported by the feeding support assembly 4, and the clamping movable seat 1-4 is slidingly connected to the feed guide rails 1-7 through a slider; it also includes a feed screw 1-3 that is rotatably connected to the feed mounting seat 1-1 and arranged parallel to the feed guide rails 1-7, and the clamping movable seat 1-4 is connected to the feed screw 1-3 through a nut; it also includes a feed motor 1-2 installed on the feed mounting seat 1-1, which is used to drive the feed screw 1-3 to rotate.

[0030] The clamping feed assembly 1 also includes two groups of mounting seats installed at both ends of the feed mounting seat 1-1. Anti-collision blocks are installed on the opposite surfaces of the two groups of mounting seats. The above-mentioned anti-collision blocks are made of rubber material. The position of the clamping movable seat 1-4 can be limited by the above-mentioned setting.

[0031] Working principle:

[0032] In actual operation, a number of pipes are stacked on the storage rack structure 5 and supported by a number of pipe-holding rods 5-2. Under the action of the pipe-stopping sheet metal 6-2 in the pipe-limiting arrangement assembly 6, the pipes at the lower end of the pipe-holding rods 5-2 are arranged in a single layer, and the pipes at the lowest end are blocked by the pipe-stopping vertical rods 5-3.

[0033] When the feeding operation is required, the jacking cylinder 3-3 is started, driving the jacking wedge block 3-5 installed thereon to move upward, and multiple groups of jacking wedge blocks 3-5 move upward synchronously to lift the pipe fitting at the lowest end. When the pipe fitting is lifted to above the pipe blocking upright rod 5-3, it will roll forward and downward. Under the guidance of the transition guide block 5-1, the pipe fitting will roll down to the feeding support assembly 4, and the two groups of feed rollers 4-6 distributed in a V shape in the feeding support assembly 4 can support the rolled pipe fitting and make the pipe fitting roll in contact with the feeding support assembly 4; at this time, the front end of the pipe fitting is between the two groups of clamping blocks 1-6 in the clamping feed assembly 1, and the clamping claw cylinder 1-5 in the clamping feed assembly 1 is started to clamp the pipe fitting, and driven by the feed motor 1-2 and the rotating feed screw 1-3, the clamping movable seat 1-4 moves along the feed guide rail 1-7, and then moves a preset distance toward the laser cutting head, thereby realizing the pipe cutting operation;

[0034] When the diameter of the cut pipe changes, the height of the pipe retaining sheet metal 6-2 is adjusted according to the outer diameter of the pipe so that the pipes can be arranged in a single layer. The lifting cylinder 3-3 is moved by rotating the adjustable screw 3-1 so that the lifting wedge block 3-5 can lift out a single pipe when it moves up and down, and the pipe falls onto the feeding support assembly 4; at the same time, the two sets of feeding rollers 4-6 are driven to move longitudinally to the appropriate position by rotating the feeding horizontal axis 4-1, so that the pipes they support can be in the cutting station when they move horizontally, thereby making the loading device suitable for pipes of different sizes.
