Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a laser cutting machine for steel plates. Background Technology

[0002] Laser cutting technology, as an indispensable processing method in modern manufacturing, has already occupied an important position in the field of metal processing. Steel plate laser cutting machines use high-energy-density laser beams to precisely cut steel plates, and have significant advantages such as high precision, high speed, and good flexibility. They are gradually replacing traditional mechanical cutting, plasma cutting, and flame cutting processes.

[0003] In existing steel plate laser cutting machines, the welded support bar (or cutting support bar, worktable support bar) is usually fixedly installed as an integral part of the machine's worktable. This structure has the following drawbacks in practical use: 1. Because the welded support bar is subjected to the high-temperature molten slag and metal spatter from laser cutting for extended periods, it is prone to burning, deformation, or slag accumulation. However, in existing equipment, the support bar is fixedly connected to the worktable, and disassembly and replacement require machine shutdown, a cumbersome process that affects production efficiency. 2. When the support bar needs to be replaced or cleaned, the entire cutting process must be paused, resulting in long downtime and preventing parallel "cleaning-cutting" operations, thus reducing work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a steel plate laser cutting machine.

[0005] The technical solution of this utility model is a steel plate laser cutting machine, which includes a machine body and a support bar mounting assembly; The equipment body includes a frame, a gantry frame slidably mounted on the upper part of the frame, and a laser cutting machine slidably mounted on the gantry frame. A support bar mounting assembly is located inside the frame, comprising two first slide rods and two second slide rods. The two first slide rods are located between the two second slide rods, and the first and second slide rods on the same side are slidably connected. First connecting crossbars connect the outer ends of the two first slide rods and the outer ends of the two second slide rods. Multiple support bar mounting seats are arranged side-by-side on both sides inside the frame, and each support bar mounting seat has a limiting mechanism for the ends of the support bars to engage. Each of the two adjacent support bar mounting seats has a connecting rope. Two sliders are connected to the bottom of each support bar mounting seat. The first and second slide rods each have sliding holes for the sliders to slide through. Four support bar mounting seats located at the corners are fixedly connected to the corresponding first or second slide rod. A drive assembly for moving the first slide rod is installed on one side of the second slide rod. An L-shaped support frame is rotatably connected to the bottom of each of the two second slide rods. A cylinder is rotatably mounted on the L-shaped support frame, and the output end of the cylinder is hinged to the second slide rod. A first support leg is vertically connected to the bottom of each of the two first slide rods.

[0006] Preferably, limit plates are provided at both ends of the inner sidewall of the frame.

[0007] Preferably, both ends of the two limiting plates are threaded with bolts, and a turntable is connected to the upper end of the bolts.

[0008] Preferably, a second connecting crossbar is connected between the bottom ends of the two first legs, a fourth sliding bar is connected to the second connecting crossbar, a third sliding bar is slidably connected to one side of the fourth sliding bar, the third sliding bar is connected to the first connecting crossbar on the side away from the second connecting crossbar, and multiple support pillars are arranged side by side on both the third and fourth sliding bars, and a support block is provided at the middle of the bottom end of each of the multiple support bars.

[0009] Preferably, the ends of the two first sliding rods furthest from the first leg are vertically connected to a second leg.

[0010] Preferably, the bottom ends of the L-shaped support frame and the first leg are equipped with self-locking casters.

[0011] Preferably, each of the first slide rods on both sides is connected to a movable rod, and each of the second slide rods on both sides is connected to a U-shaped component. The movable rods on both sides movably pass through the U-shaped components on both sides. The drive assembly includes a servo motor and a threaded rod. The servo motor is mounted on the second slide rod, and the threaded rod is connected to the output shaft of the servo motor. A threaded groove adapted to the threaded rod is opened on the movable rod adjacent to the threaded rod.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects: The frame and support bar mounting assembly adopt a separate structure. When cleaning multiple support bars, the support bar mounting assembly can be removed from the inside of the frame before cleaning, and the operation is unimpeded, which improves work efficiency. In addition, if multiple support bar mounting assemblies are set, new support bar mounting assemblies can be pushed into the inside of the frame, reducing welding waiting time.

[0013] The support bar mounting assembly is telescopic, which reduces its footprint when shortened, making it easier to place.

[0014] The support bar assembly allows for easy adjustment of its tilt angle. Once the support bar assembly is adjusted to a certain tilt angle, the waste material slides down through the upper ends of multiple support bars, achieving the function of automatic unloading.

Detailed Implementation

[0019] Example 1 like Figures 1-4 As shown in the figure, the steel plate laser cutting machine proposed in this embodiment includes a machine body and a support bar mounting assembly.

[0020] The equipment body includes a frame 1, a gantry 2 that is slidably mounted on the upper end of the frame 1, and a laser cutting machine 3 that is slidably mounted on the gantry 2.

[0021] The support bar mounting assembly is located inside the frame 1. The support bar mounting assembly includes two first slide bars 41 and two second slide bars 42. The two first slide bars 41 are located between the two second slide bars 42. The first slide bars 41 and the second slide bars 42 on the same side are slidably connected. A first connecting crossbar 18 is connected between the outer ends of the two first slide bars 41 and between the outer ends of the two second slide bars 42. A second support leg 19 is vertically connected to the end of the two first slide bars 41 away from the first support leg 13.

[0022] Multiple support bar mounting seats 5 are arranged side by side on both sides of the inside of the frame 1. Each support bar mounting seat 5 has a limiting hole for the end of the support bar 7 to be inserted. A connecting rope 6 is connected between two adjacent support bar mounting seats 5. Two sliders 51 are connected to the bottom of the support bar mounting seat 5. The first slider 41 and the second slider 42 are both provided with sliding holes 401 for the sliders 51 to slide. The four support bar mounting seats 5 located at the corners are fixedly connected to the first slider 41 or the second slider 42 on the corresponding side.

[0023] A drive assembly for driving the first slide rod 41 to move is installed on the second slide rod 42 on one side. A moving rod 8 is connected to the first slide rod 41 on both sides. A U-shaped part 9 is connected to the second slide rod 42 on both sides. The moving rods 8 on both sides move through the U-shaped parts 9 on both sides respectively. The drive assembly includes a servo motor 10 and a threaded rod 11. The servo motor 10 is installed on the second slide rod 42. The threaded rod 11 is connected to the output shaft of the servo motor 10. A threaded groove adapted to the threaded rod 11 is opened on the moving rod 8 on the side adjacent to the threaded rod 11.

[0024] The bottom ends of the two second slide rods 42 are rotatably connected to L-shaped support frames 12, and cylinders 15 are rotatably mounted on the L-shaped support frames 12. The output end of the cylinders 15 is hinged to the second slide rods 42. The bottom ends of the two first slide rods 41 are vertically connected to first legs 13. The bottom ends of the L-shaped support frames 12 and the first legs 13 are all equipped with self-locking casters 14.

[0025] A second connecting crossbar 23 is connected between the bottom ends of the two first legs 13. A fourth sliding rod 162 is connected to the second connecting crossbar 23. A third sliding rod 161 is slidably connected to one side of the fourth sliding rod 162. The third sliding rod 161 is connected to the first connecting crossbar 18 on the side away from the second connecting crossbar 23. Multiple support columns 17 are arranged side by side on both the third sliding rod 161 and the fourth sliding rod 162. A support block 71 is provided at the middle of the bottom end of each of the multiple support bars 7. The support block 71 covers the upper end of the support column 17. The above structure can prevent dripping welding slag from adhering to the contact position between the support block 71 and the support column 17.

[0026] It should be added that a PLC controller is used to control the equipment in this technical solution.

[0027] In this embodiment, a first motor linear module for driving the gantry 2 to move is installed on the frame 1, and a second motor linear module for driving the laser cutting machine 3 to move is installed on the gantry 2. The horizontal driving of the laser cutting machine 3 is achieved through the cooperation of the first motor linear module and the second motor linear module. The above is the prior art, so it will not be described in detail.

[0028] In this technical solution, the frame 1 and the mounting components are separate structures. When cleaning the welding slag on the support bars 7, the mounting components can be pushed out from the inside of the frame 1. After being pushed out, the cleaning process is more convenient and the operation is not obstructed. At the same time, a new mounting component with multiple support bars 7 can be pushed into the inside of the frame 1, which can reduce the impact on the efficiency of steel plate welding construction and realize the rapid connection of welding work.

[0029] The drive component can be set to extend the support bar mounting component to its maximum length or retract it to its minimum length. When the support bar mounting component is retracted to its minimum length, the distance between two adjacent support bars 7 is reduced, thereby reducing the space occupied by the component. When the support bar mounting component is extended to its maximum length, multiple connecting ropes 6 are taut, making the distance between two adjacent support bars 7 the maximum to meet the requirements of supporting steel plate cutting.

[0030] After the finished product is removed, the large pieces of waste material fall onto multiple support bars 7. The cylinder 15 can be activated to drive the extension. The extension causes the support bar mounting assembly to rotate. After the support bar mounting assembly rotates, its upper surface tilts at a certain angle, allowing the waste material to slide smoothly from the top of the multiple support bars 7, thus realizing the automatic unloading function.

[0031] Example 2 like Figure 1 As shown in the figure, the steel plate laser cutting machine proposed in this embodiment has a limit plate 20 at both ends of the inner sidewall of the frame 1 compared to the first embodiment. The limit plate 20 is used to limit the placement of the steel plate and can also prevent welding slag from falling into both ends of the support bar mounting assembly.

[0032] Both ends of the two limiting plates 20 are threaded with bolts 22, and the upper end of the bolts 22 is connected to a turntable 21. After the support bar mounting assembly is pushed into the inner side of the frame 1, the turntable 21 drives the bolts 22 to rotate, so that the bolts 22 are pressed against the support bar mounting assembly, which is used to limit the support bar mounting assembly and prevent it from shaking.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
