Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1:

[0038] Please see Figure 1-12 As shown, this utility model is a horizontal three-chuck laser tube cutting machine, including a cutting host 1, a short material flipping mechanism 2, and a material unloading enclosure 3 mounted on the machine bed; a semi-automatic feeding structure 4 mounted on the feeding end side of the machine bed; and a material frame 5 mounted on the unloading end side of the machine bed. The short material flipping mechanism 2 is located on the unloading side of the cutting host 1 on the machine bed, and the material unloading enclosure 3 is mounted on the machine bed and the short material flipping mechanism 2. The cutting host 1 is fixedly mounted on the machine bed and is the core component for performing laser tube cutting operations. It uses a high-power laser generator and a precision cutting head, enabling high-precision and high-efficiency cutting of various metal tubes.

[0039] The short material flipping mechanism 2 includes a flat plate support 21, a waste material flipping plate 22, a flat plate support cylinder 23, a waste material flipping plate cylinder 24, a first follower reducer 25, a first follower motor 26, a fourth fixed base 27, and a follower support frame 28.

[0040] The fourth fixed base 27 is vertically fixed to the bed. The follower support frame 28 is vertically mounted on the fourth fixed base 27 via two sets of linear sliders and linear guide mechanisms. The first follower motor 26 and the first follower reducer 25 are integrated and mounted on the fourth fixed base 27. A vertically arranged third rack is mounted on the follower support frame 28. A third gear that meshes with the third rack is mounted on the output shaft of the first follower reducer 25. The first follower motor 26 drives the first follower reducer 25 to rotate, and the meshing of the third gear and the third rack drives the follower support frame 28 to move up and down, achieving follower adjustment for different pipe materials. One end of the flat plate support 21 is hinged to the upper end of the follower support frame 28 via a hinge seat. The flat plate support cylinder 23 is installed between the follower support frame 28 and the flat plate support 21. The retraction of the flat plate support cylinder 23 unloads the processed pipe material from the flat plate support 21. The waste tipping plate 22 is hinged to one end of the flat plate support 21 adjacent to the cutting host 1 via a hinge seat; the waste tipping plate cylinder 24 is installed between the flat plate support 21 and the waste tipping plate 22, and the retraction of the waste tipping plate cylinder 24 realizes the dumping of the waste cut off on the waste tipping plate 22.

[0041] The first follower motor 26 drives the first follower reducer 25 to move, which in turn drives the overall short material flipping mechanism 2 to follow the support of the pipe. The flat support 21 mainly plays a supporting role. When cutting waste material, the waste material flipping cylinder 24 retracts, and the waste material flipping plate 22 flips down. The waste material on the waste material flipping plate 22 falls into the waste material collection frame 7 placed under the bed. When the cutting of finished material is completed, the flat support cylinder 23 retracts and drops the finished material into the finished material frame 5. This completes the short material cutting and unloading process.

[0042] The material unloading enclosure 3 includes a first fixed base 31, a switch door 32, a light-blocking curtain 33, a first lighting lamp 34, and a gas spring 35. The material frame 5 is located on one side of the light-blocking curtain 33. The first fixed base 31 serves to fix the entire structure, with feet supporting its lower end, and rests on the machine bed. The switch door 32 is connected to the first fixed base 31 via hinges and gas springs 35, and at least two switch doors 32 are installed on the first fixed base 31. The light-blocking curtain 33 is installed on the switch door 32 at the end away from the hinge. The light-blocking curtain 33 mainly prevents internal dust and light from leaking out. When maintenance is required, the switch door 32 is opened, and the gas spring 35 supports the opening of the switch door 32 structure, maintaining the switch door 32 in a stable open state under the supporting force of the extended gas spring 35. Multiple first lighting lamps 34 are installed inside the first fixed base 31, and all the internal first lighting lamps 34 are in the on state for easy observation of the internal processing status.

[0043] The semi-automatic feeding structure 4 includes a feeding arm reduction motor 41, a chain 42, three single feeding assemblies 43, a feeding reduction motor 44, a feeding shaft 45, and a feeding arm shaft 46. Each single feeding assembly 43 is equipped with a chain 42. The three parallel single feeding assemblies 43 are connected as one unit by profiles. Both the feeding arm reduction motor 41 and the feeding reduction motor 44 are mounted on the middle single feeding assembly 43. The feeding reduction motor 44 drives the feeding shaft 45 to rotate. Three sprockets are mounted on the feeding shaft 45, each driving the chains 42 mounted on the three single feeding assemblies 43 to move synchronously.

[0044] The single-unit feeding assembly 43 includes a third fixed base 431, a feeding cylinder 432, a second lifting cylinder 433, a lifting seat 434, a feeding arm 435, and a second lifting cylinder mounting base 436. The feeding arm 435 is horizontally mounted on one side of the third fixed base 431 via a set of fifth linear sliders and a linear guide mechanism. A second rack is mounted below the feeding arm 435. The second lifting cylinder mounting base 436 is horizontally mounted on the outer side of the feeding arm 435 via a set of fifth linear sliders and a linear guide mechanism. The feeding cylinder 432 is mounted on the outer side of the feeding arm 435, and its extension / retraction end is connected to the second lifting cylinder mounting base 436. The lifting seat 434 is mounted on the extension / retraction end of the second lifting cylinder 433, which is a linearly guided cylinder. The feeding arm reduction motor 41 drives the feeding arm shaft 46 to rotate. Three second gears, each engaging with a second rack, are mounted on the feeding arm shaft 46.

[0045] The pipes are placed on the chain. During feeding, the feeding reduction motor 44 drives the feeding shaft 45 to rotate, which in turn moves the three sets of single feeding components 43 synchronously. The feeding shaft 45 drives the sprocket and chain 42 to rotate, feeding the material forward. When it reaches the front, multiple cylinders deliver the material to the feeding arm 435. The feeding arm reduction motor 41 drives the feeding arm 435 to move, feeding the material forward.

[0046] When the chain transports the material, the second lifting cylinder 433 drives the lifting seat 434 to rise, and then the feeding cylinder 432 pushes the second lifting cylinder mounting base 436 and the lifting seat 434 supporting the pipe to move forward. Then the second lifting cylinder 433 descends, dropping the pipe onto the feeding arm 435. Then the feeding arm reduction motor 41 drives the second gear rack to transport the feeding arm 435 and the pipe on it forward.

[0047] Four follower support structures 6 are installed on the feed side of the cutting machine bed located on the cutting host 1. Each follower support structure 6 includes a second fixed base 61, a follower motor 62, a follower reducer 63, a lifting slide plate 64, support rollers 65, a first rack 66, a clamping cylinder 67, a sliding seat 68, a connecting rod 69, clamping rollers 610, a first lifting cylinder 611, and a clamping lifting slide plate 612. The second fixed base 61 is fixed to the machine bed. The lifting slide plate 64 is vertically mounted on one side of the second fixed base 61 via two sets of first linear sliders and a linear guide mechanism, and the first rack 66 is mounted on the side of the lifting slide plate 64 opposite to the second fixed base 61. The follower motor 62 and the follower reducer 63 are assembled as a single unit and mounted on the opposite side of the second fixed base 61. A gear for driving the first rack 66 to move up and down is mounted on the output shaft of the follower reducer 63. The follower motor 62 and the follower reducer 63 indirectly drive the lifting slide plate 64 to move up and down. The support roller 65 is fixed to the upper end of the lifting slide plate 64 and mainly supports the pipe.

[0048] The clamping lifting slide plate 612 is vertically mounted on the other side of the lifting slide plate 64 via two sets of second linear sliders and linear guide rail mechanism. A first lifting cylinder 611 is installed between the lifting slide plate 64 and the clamping lifting slide plate 612 to raise or lower the entire clamping mechanism, avoiding interference during the movement of the rear chuck of the horizontal three-chuck laser tube cutting machine.

[0049] The sliding seat 68 is vertically mounted on the other side of the clamping lifting slide plate 612 via a set of third linear sliders and a linear guide mechanism. The clamping cylinder 67 is mounted on the lower end of the clamping lifting slide plate 612. The telescopic end of the clamping cylinder 67 is connected to the sliding seat 68.

[0050] A pair of clamping rollers 610 are horizontally mounted on the outer side of the upper end of the sliding seat 68 via a set of fourth linear sliders and linear guide mechanisms. Each pair of clamping rollers 610 is connected to the sliding seat 68 via a connecting rod 69. When the clamping cylinder 67 retracts, it causes the sliding seat 68 to move downward, which in turn causes the connecting rod 69 to move, thereby causing the pair of clamping rollers 610 to center and clamp the pipe.

[0051] The horizontal three-chuck laser tube cutting machine of this embodiment achieves efficient, precise, and safe laser cutting of tubes through the coordinated operation of the aforementioned components. Its modular design makes equipment maintenance and upkeep more convenient, reducing maintenance costs and downtime. At the same time, the fully enclosed processing area and automated loading and unloading system significantly improve the working environment, reduce the labor intensity of operators, and increase work efficiency and comfort.
