[0003] At present, laser cutting equipment used for cutting hardware decorative parts requires manual removal of the cut workpiece before placing a new workpiece. The operation is cumbersome and inconvenient, and the workload of the user is large, resulting in low efficiency of laser cutting of hardware decorative parts. Summary of the invention

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art: the laser cutting equipment currently used for cutting hardware decorative parts requires manual removal of the cut workpiece before placing a new workpiece, which is cumbersome and inconvenient to operate and requires a large workload for the user. The efficiency of laser cutting of hardware decorative parts is low, and a laser cutting equipment for processing hardware decorative parts is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A laser cutting device for processing hardware decorative parts, comprising a processing table and a laser cutting head, wherein a support seat is fixedly mounted on the processing table, a bearing plate is rotatably mounted on the support seat, and a storage frame is provided on one side of the processing table; A support plate with an L-shaped cross section is fixedly connected to the bottom of the processing table, a slide groove is provided on the support plate, a sliding assembly is provided in the slide groove, and the sliding assembly includes a slider slidably installed in the slide groove, a first spring is fixedly connected to a side surface of the slider, the first spring is fixedly connected to the inner wall of the slide groove, a support rod is fixedly connected to the upper surface of the slider, a groove with a right-angled triangle cross section is provided on the lower surface of the bearing plate, and the upper end of the support rod is in contact with the oblique inner wall of the groove; A hydraulic cylinder is fixedly connected to the support plate, a bending rod is fixedly connected to the driving end of the hydraulic cylinder, an extrusion rod is fixedly connected to one side of the bending rod, a limited position opening is provided on the slider, and two symmetrically arranged moving blocks are slidably connected to the processing table, and each of the moving blocks is provided with a clamping assembly.

[0006] Preferably, each of the clamping assemblies comprises a bracket slidably mounted on the moving block, the bracket being provided with a plurality of mounting grooves arranged at equal distances, wherein two of the mounting grooves are clamped with T-shaped clamping plates.

[0007] Preferably, a plurality of slide bars arranged in a ring array are slidably installed in each of the installation grooves, one end of each of the slide bars is fixedly connected to an inclined extrusion plate, and the surface of each of the extrusion plates fits the surface of the corresponding T-shaped clamp plate.

[0008] Preferably, each of the slide bars is sleeved with a second spring, one end of the second spring is fixedly connected to the slide bar, and the other end of the second spring is fixedly connected to the inner wall of the corresponding mounting groove.

[0009] Preferably, a movable groove is provided on the support plate, a slide plate is slidably connected in the movable groove, a hinge rod is hinged at the bottom of each movable block, and one end of each hinge rod away from the corresponding movable block is hinged to the slide plate.

[0010] Preferably, a third spring is fixedly connected to the slide plate, and one end of the third spring away from the slide plate is fixedly connected to the surface of the processing table.

[0011] Preferably, each of the moving blocks is connected to the bracket via a bolt, a groove is provided at one end of the moving block, and a threaded groove is provided on the inner wall of each of the grooves.

[0014] Compared with the prior art, the present invention has the following beneficial effects: When the hydraulic cylinder drives the bending rod to move upward, one end of the extrusion rod will move against the inclined surface of the limit opening, thereby causing the slider to slide inside the slide groove. In the initial state, the upper end of the support rod fits the inclined inner wall of the slot, and the load-bearing plate is arranged horizontally. After the support rod moves with the slider, the end of the load-bearing plate close to the storage frame will deflect downward under the action of gravity, and the load-bearing plate will change from a horizontal state to an inclined state. The workpiece on the load-bearing plate that has been laser cut will slide into the storage frame for collection under the action of gravity. There is no need to manually remove the cut workpiece, and a new workpiece can be placed directly. The operation is relatively convenient and quick, and the user's workload is small. The efficiency of laser cutting of hardware decorative parts is high. As the slide plate moves downward along the moving groove, the angle between the two hinged rods becomes smaller, the two moving blocks slide relative to the processing table at the same time, and the distance between the two moving blocks also becomes smaller. Under the transmission action of the moving blocks, the two brackets will move toward the surface close to the workpiece until the surfaces of each T-shaped clamping plate are respectively in close contact with the two side surfaces of the workpiece, so that the workpiece can be clamped and fixed, avoiding the workpiece from being offset during the subsequent cutting process, which is beneficial to the laser cutting of the workpiece.

A storage frame 14 is provided on one side of the processing table 1. A support plate 2 with an L-shaped cross section is fixedly connected to the bottom of the processing table 1. A slide groove is provided on the support plate 2, and a sliding component is provided in the slide groove. The sliding component includes a slider 24 slidably installed in the slide groove. A first spring 23 is fixedly connected to a side surface of the slider 24, and the first spring 23 is fixedly connected to the inner wall of the slide groove. A support rod 25 is fixedly connected to the upper surface of the slider 24. A slot 26 with a right-angled triangle cross section is provided on the lower surface of the bearing plate 5, and the upper end of the support rod 25 is in contact with the oblique inner wall of the slot 26.

[0019] A hydraulic cylinder 22 is fixedly connected to the support plate 2, a bending rod 17 is fixedly connected to the driving end of the hydraulic cylinder 22, an extrusion rod 19 is fixedly connected to one side of the bending rod 17, a limited position opening 18 is provided on the slider 24, two symmetrically arranged moving blocks 3 are slidably connected to the processing table 1, each moving block 3 is provided with a clamping assembly, each clamping assembly includes a bracket 9 slidably mounted on the moving block 3, a plurality of equidistant mounting grooves 15 are provided on the bracket 9, two of which are clamped with T-shaped clamps 10.

[0020] A moving groove 21 is provided on the support plate 2, and a slide plate 16 is slidably connected in the moving groove 21. A hinge rod 13 is hinged at the bottom of each moving block 3, and one end of each hinge rod 13 away from the corresponding moving block 3 is hinged to the slide plate 16. A third spring 20 is fixedly connected to the slide plate 16, and one end of the third spring 20 away from the slide plate 16 is fixedly connected to the surface of the processing table 1. When the slide plate 16 moves downward along the moving groove 21, the third spring 20 is deformed, and the angle between the two hinge rods 13 becomes smaller. The two moving blocks 3 slide relative to the processing table 1 at the same time, and the distance between the two moving blocks 3 also becomes smaller. Under the transmission action of the moving block 3, the two brackets 9 will move toward the surface close to the workpiece until the surfaces of each T-shaped clamping plate 10 are respectively in close contact with the two side surfaces of the workpiece, so that the workpiece can be clamped and fixed.

[0021] A plurality of slide bars 29 arranged in a circular array are slidably installed in each mounting groove 15, and one end of each slide bar 29 is fixedly connected to an inclined extrusion plate 27, and the surface of each extrusion plate 27 fits the surface of the corresponding T-shaped clamping plate 10. A second spring 28 is sleeved on each slide bar 29, and one end of the second spring 28 is fixedly connected to the slide bar 29, and the other end of the second spring 28 is fixedly connected to the inner wall of the corresponding mounting groove 15. When one end of the T-shaped clamping plate 10 is inserted into the mounting groove 15, the surface of the T-shaped clamping plate 10 will gradually contact the surface of each extrusion plate 27, and each slide bar 29 will slide relative to the bracket 9 at the same time. Under the elastic force of the second spring 28, the plurality of extrusion plates 27 will respectively fit the side surfaces of the T-shaped clamping plate 10, so that the T-shaped clamping plate 10 can be fixed, and the T-shaped clamping plate 10 and the bracket 9 can be firmly installed together. Similarly, it is also convenient to disassemble and replace the T-shaped clamping plate 10.

[0022] Each moving block 3 is connected to the bracket 9 by a bolt 4. A groove is provided at one end of the moving block 3. A threaded groove is provided on the inner wall of each groove. One end of the bracket 9 is inserted into the groove of the moving block 3. Then, one end of the bolt 4 passes through the bracket 9 and is threadedly connected to the threaded groove. The bracket 9 and the moving block 3 can be firmly installed together. A mounting frame 11 is fixedly connected to the processing table 1. A reciprocating screw rod 6 is rotatably connected to the mounting frame 11. A mounting block 7 is threadedly connected to the reciprocating screw rod 6. The mounting block 7 is slidably connected to the processing table 1. An electric push rod is fixedly installed at the bottom of block 7, and the driving end of the electric push rod is fixedly connected to the laser cutting head 8. A servo motor is fixedly installed on the processing table 1, and the driving end of the servo motor is fixedly connected to the reciprocating screw 6. The electric push rod drives the laser cutting head 8 to move down to a suitable height, and the servo motor drives the reciprocating screw 6 to rotate. The mounting block 7 will move along the reciprocating screw 6 and slide relative to the processing table 1. When the laser cutting head 8 moves with the mounting block 7, the workpiece on the supporting plate 5 can be laser cut.

[0023] In the present invention, when in use, first place the workpiece to be processed on the carrying plate 5, and then the hydraulic cylinder 22 drives the bending rod 17 to move downward. During the downward movement of the bending rod 17, it will gradually press against the upper surface of the slide plate 16 and move downward together. During this process, the extrusion rod 19 does not contact the slider 24. During the downward movement of the slide plate 16 along the moving groove 21, the third spring 20 is deformed, and the inclination angle of each hinge rod 13 will change, the angle between the two hinge rods 13 will become smaller, and the two moving blocks 3 will slide relative to the processing table 1 at the same time, and the distance between the two moving blocks 3 will also become smaller. Under the transmission action of the moving block 3, the two brackets 9 will move toward the surface close to the workpiece until the surfaces of each T-shaped clamping plate 10 are respectively in close contact with the two side surfaces of the workpiece, so that the workpiece can be clamped and fixed, avoiding the workpiece from being offset during the subsequent cutting process, which is beneficial to the laser cutting process of the workpiece.

[0024] After that, the electric push rod drives the laser cutting head 8 to move down to a suitable height, and the servo motor drives the reciprocating screw 6 to rotate, and the mounting block 7 moves along the reciprocating screw 6 and slides relative to the processing table 1. During the movement of the laser cutting head 8 along with the mounting block 7, the workpiece on the supporting plate 5 can be laser cut. When the workpiece cutting process is completed, the electric push rod drives the laser cutting head 8 to move up to a suitable height, and then the hydraulic cylinder 22 drives the bending rod 17 to move up. During the movement of the bending rod 17, it will gradually separate from the slide plate 16. Under the elastic force of the third spring 20, the slide plate 16 will move up to the initial height. At this time, each T-shaped clamp 10 is not in contact with the workpiece and the supporting plate 5, and the subsequent bending rod 17 continues to move up. In the process, one end of the extrusion rod 19 will move against the inclined surface of the limit opening 18, thereby making the slider 24 slide inside the slide groove, and the first spring 23 will be deformed. In the initial state, the upper end of the support rod 25 is in contact with the inclined inner wall of the slot 26, and the carrying plate 5 is arranged horizontally. After the support rod 25 moves with the slider 24, the end of the carrying plate 5 close to the storage frame 14 will deflect downward under the action of gravity, and the carrying plate 5 will change from a horizontal state to an inclined state. The workpiece on the carrying plate 5 after laser cutting will slide into the storage frame 14 for collection under the action of gravity. There is no need to manually remove the cut workpiece, and a new workpiece can be placed directly. The operation is relatively convenient and quick, and the user's workload is small, and the efficiency of laser cutting of hardware decorative parts is high.
