Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and in particular to a feeding mechanism and feeding method for a laser cutting machine. Background Technology

[0002] Laser cutting machines use a focused, high-energy laser to irradiate the surface of a material, rapidly heating it to vaporization, melting, or ignition point. Simultaneously, a high-speed airflow coaxial with the laser beam removes the molten material, thus achieving the cutting of the material. Some cylindrical workpieces are cut using laser cutting machines, although this process is time-consuming and labor-intensive.

[0003] In the process of cutting pipe fittings, a feeding mechanism is used to install the tubular workpiece for cutting. However, the feeding mechanism can only install one tubular workpiece for each cut. After the tubular workpiece is cut, it is necessary to manually add more tubular workpieces. The feeding frequency is frequent, and manual unloading is also required after each cut. This is time-consuming and labor-intensive, and the cutting efficiency of tubular workpieces is low. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a feeding mechanism and method for a laser cutting machine. The specific technical solution is as follows:

[0005] One objective of this invention is to improve the feeding mechanism of a laser cutting machine, comprising a base, a frame fixedly connected to one side of the top of the base, a laser cutting machine body mounted on the frame, a feeding assembly disposed on the top side of the base away from the frame, the feeding assembly comprising a feeding shell inclined to the base, a feeding chamber for material being disposed inside the feeding shell, and a discharging component disposed on one side of the bottom of the feeding shell, the discharging component allowing a material contained at the bottom of the feeding chamber to detach to the outside of the bottom of the feeding shell.

[0006] As an improvement to the above technical solution: the feeding component includes a mounting bracket fixedly connected to one side of the bottom outer wall of the feeding shell. The feeding shell has two openings on the side near the mounting bracket. A first baffle is slidably connected in one of the openings, and a second baffle is slidably connected in the other opening. The first baffle is closer to the bottom of the feeding shell than the second baffle. Two second hydraulic cylinders are fixedly installed on the inner side wall of the mounting bracket. The output rod of one of the second hydraulic cylinders is fixedly connected to one end of the first baffle, and the output rod of the other second hydraulic cylinder is fixedly connected to one end of the second baffle.

[0007] As an improvement to the above technical solution: a material fixing component is provided on the top side of the base near the feeding component. The material fixing component includes a movable frame that is slidably connected to the top surface of the base. Two sets of material fixing frames are provided on the top of the movable frame. A fourth hydraulic cylinder is fixedly installed on both sides of the top of the movable frame. Each fourth hydraulic cylinder is fixedly connected to one material fixing frame. A side plate is fixedly connected to one end of the inner side of the material fixing frame.

[0008] As an improvement to the above technical solution: the material holder is U-shaped, and the bottom of the inner sidewall of the material holder is arc-shaped.

[0009] As an improvement to the above technical solution: a guide assembly is also provided on one side of the bottom of the feeding shell. The guide assembly includes a guide shell fixedly connected to one side of the bottom of the feeding shell and two guide blocks symmetrically arranged on the inner bottom of the feeding shell. A drive motor is fixedly installed on one side of the inner wall of the guide shell. A threaded rod is fixedly connected to the output rod of the drive motor. Two nut sleeves are symmetrically threaded on the surface of the threaded rod. Each nut sleeve is fixedly connected to one side of one of the guide blocks through a connecting rod.

[0010] As an improvement to the above technical solution, the guide block is arranged in a trapezoidal shape.

[0011] As an improvement to the above technical solution: a third hydraulic cylinder is fixedly installed on the side of the material holding rack away from the side plate by a mounting bracket, a push plate is provided on the inner side of the material holding rack, and the output rod of the third hydraulic cylinder is fixedly connected to one side of the push plate.

[0012] As an improvement to the above technical solution: a first hydraulic cylinder is fixedly installed on the top of the base near the frame, the output rod of the first hydraulic cylinder is fixedly connected to one side of the moving frame, a discharge port is opened in the middle of the base, and a receiving box is provided at the bottom of the base.

[0013] The second objective of this invention is to provide a method for feeding a laser cutting machine, using the aforementioned laser cutting machine feeding mechanism, which includes the following steps:

[0014] Step 1, Loading: Load multiple materials into the loading chamber of the loading assembly;

[0015] Step 2, unloading: The material at the bottom of the feeding chamber is released by the unloading device and detached to the outside of the bottom of the feeding shell, and then slides down to the inside of the fixed frame.

[0016] Step 3, securing the material: The fourth hydraulic cylinder drives two securing frames to clamp and fix the two ends of the material.

[0017] Step 4, Cutting: The material clamped on the moving frame is moved to the side of the discharge port by the first hydraulic cylinder, and then the material is cut by the laser cutting machine body;

[0018] Step 5, Unloading: After the material is cut, the third hydraulic cylinder drives the push plate to push the material, and the material falls into the receiving box through the discharge port, completing the unloading.

[0019] The beneficial effects of this invention are as follows: mainly through the cooperation of the feeding component, the fixing component and the guiding component, the feeding component can accommodate multiple material pipes, and then the material pipes are gradually unloaded. After the material pipes are cut, the cut material pipes can be automatically unloaded, saving time and effort and improving cutting efficiency. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example

[0029] For the laser cutting machine's feeding mechanism, please refer to... Figures 1-7 The system includes a base 1, with a frame 21 fixedly connected to one side of the top of the base 1. The frame 21 is equipped with a laser cutting machine body 2. Specifically, the frame 21 is connected to the laser cutting machine body 2 through a lead screw mechanism. The lead screw mechanism mainly consists of a lead screw and a motor. The lead screw mechanism drives the laser cutting machine body 2 to move back and forth above the base 1. A cylinder or hydraulic cylinder can be installed below the lead screw mechanism to drive the laser cutting machine body 2 to move up and down, so as to facilitate the adjustment of the position of the laser cutting machine body 2. A feeding assembly 4 is provided on the top side of the base 1 away from the frame 21. The feeding assembly 4 includes a feeding shell 41 that is inclined to the base 1.

[0030] Specifically, the bottom end of the feeding shell 41 is fixedly connected to the base 1 via a bracket. The feeding shell 41 is provided with a feeding chamber 40 for materials. Specifically, the angle between the feeding shell 41 and the top horizontal plane of the base 1 is 30-60 degrees, which allows the materials in the feeding chamber 40 to slide freely to the bottom end of the feeding chamber 40 by gravity. A material discharge component is provided on one side of the bottom of the feeding shell 41. The material discharge component allows the material at the bottommost end of the feeding chamber 40 to be released to the outside of the bottom end of the feeding shell 41. Specifically, the feeding chamber 40 is rectangular.

[0031] In an optional embodiment: the feeding component includes a mounting bracket 45 fixedly connected to one side of the bottom outer wall of the feeding shell 41. The feeding shell 41 has two openings 410 on the side near the mounting bracket 45. Specifically, one end of the opening 410 extends into the feeding cavity 40, and the other end extends into the outer side of the feeding shell 41. A first baffle 42 is slidably connected in one opening 410, and a second baffle 43 is slidably connected in the other opening 410. The first baffle 42 is closer to the bottom of the feeding shell 41 than the second baffle 43. Two second hydraulic cylinders 44 are fixedly installed on the inner side wall of the mounting bracket 45. The output rod of one second hydraulic cylinder 44 is fixedly connected to one end of the first baffle 42, and the output rod of the other second hydraulic cylinder 44 is fixedly connected to one end of the second baffle 43.

[0032] In an optional embodiment: a material fixing component 5 is provided on the top side of the base 1 near the feeding component 4. The material fixing component 5 includes a movable frame 51 that is slidably connected to the top surface of the base 1. Two sets of material fixing frames 52 are provided on the top of the movable frame 51. A fourth hydraulic cylinder 56 is fixedly installed on both sides of the top of the movable frame 51. Each fourth hydraulic cylinder 56 is fixedly connected to a material fixing frame 52. A side plate 54 is fixedly connected to one end of the inner side of the material fixing frame 52.

[0033] In an optional embodiment: the material holder 52 is U-shaped and the bottom of the inner side wall of the material holder 52 is arc-shaped, so that the material pipe that falls out from the bottom of the feeding chamber 40 can be better guided into the side plate 54. Then, the fourth hydraulic cylinder 56 is controlled to drive the two material holders 52 to move in opposite directions, so that the side plate 54 fixes the material to facilitate the subsequent cutting of the material.

[0034] In an optional embodiment: a guide assembly 7 is also provided on one side of the bottom of the feeding shell 41. The guide assembly 7 includes a guide shell 71 fixedly connected to one side of the bottom end of the feeding shell 41 and two guide blocks 76 symmetrically arranged on the bottom inner side of the feeding shell 41. A drive motor 72 is fixedly installed on one side of the inner wall of the guide shell 71. A threaded rod 74 is fixedly connected to the output rod of the drive motor 72. Two nut sleeves 73 are symmetrically threaded on the surface of the threaded rod 74. Each nut sleeve 73 is fixedly connected to one side of one of the guide blocks 76 through a connecting rod 75.

[0035] Specifically, the guide shell 71 has a sliding opening 70 on the side near the sliding opening 70. One side of each of the two connecting rods 75 is slidably connected to the sliding opening 70. The surface of the threaded rod 74 is provided with two sets of threads with opposite directions, and the threads match the inner sidewall of the nut sleeve 73. When the threaded rod 74 is rotated, the two sets of nut sleeves 73 can move towards each other or away from each other.

[0036] In an optional embodiment: the guide block 76 is arranged in a trapezoidal shape. Specifically, the shape of the guide block 76 can facilitate the introduction of the material pipe into the port formed between the two guide blocks 76, and then the material is introduced into the material holder 52 from the port.

[0037] Furthermore, the distance between the two guide blocks 76 can be adjusted by the drive motor 72, so that the port distance formed between the two guide blocks 76 can be changed. This allows material pipes of different widths to be guided from the bottom of the upper shell 41 to between the two fixing racks 52 through the two guide blocks 76. This makes it easy to fix material pipes of different widths, which is convenient for the subsequent cutting of material pipes by the laser cutting machine body 2, making this application adaptable to cutting conditions.

[0038] In an optional embodiment: a third hydraulic cylinder 53 is fixedly mounted on the side of the material holder 52 away from the side plate 54 by a mounting bracket, a push plate 55 is provided on the inner side of the material holder 52, and the output rod of the third hydraulic cylinder 53 is fixedly connected to one side of the push plate 55.

[0039] In an optional embodiment: A first hydraulic cylinder 6 is fixedly installed on the top of the base 1 near the side of the frame 21. The output rod of the first hydraulic cylinder 6 is fixedly connected to one side of the moving frame 51. A discharge port 10 is opened in the middle of the base 1. The top and bottom of the discharge port 10 pass through the base 1. A receiving box 3 is provided at the bottom of the base 1. After the frame 21 finishes cutting the material, the third hydraulic cylinder 53 can drive the push plate 55 to push the material into the discharge port 10 and into the receiving box 3 to complete the automatic unloading. Furthermore, a controller is installed on one side of the base 1. The laser cutting machine body 2, the second hydraulic cylinder 44, the third hydraulic cylinder 53, the first hydraulic cylinder 6 and the drive motor 72 are all electrically or wirelessly connected to the controller.

[0040] In an optional embodiment: a laser cutting machine feeding method, using the above-described laser cutting machine feeding mechanism, includes the following steps:

[0041] Step 1, feeding: Load multiple materials into the feeding chamber 40 inside the feeding assembly 4;

[0042] Step 2, Unloading: The material at the bottom of the feeding chamber 40 is released by the unloading device to the outside of the bottom of the feeding shell 41, and then slides to the inside of the fixing frame 52. Specifically, during the unloading process, the second hydraulic cylinder 44 drives the first baffle 42 away from the feeding chamber 40, so the material tube at the bottom will be released from the bottom of the feeding chamber 40. Then the first baffle 42 is reset, the second baffle 43 is released from the feeding chamber 40, allowing the next material to enter the bottom of the feeding chamber 40, and then the second baffle 43 is reset, in preparation for the next material to be released from the feeding chamber 40.

[0043] Step 3, securing the material: The fourth hydraulic cylinder 56 drives the two securing frames 52 to clamp and fix the two ends of the material.

[0044] Step 4, material cutting: The material clamped on the moving frame 51 is moved to the side of the discharge port 10 by the first hydraulic cylinder 6, and then the material is cut by the laser cutting machine body 2.

[0045] Step 5, Unloading: After the material is cut, the third hydraulic cylinder 53 drives the push plate 55 to push the material, and the material falls into the receiving box 3 through the discharge port 10, thus completing the unloading.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
