Description

Technical Field

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

[0002] Laser cutting technology is widely used in industries such as heavy manufacturing, shipbuilding, and steel structures. It can significantly improve cutting accuracy and production efficiency. The common laser cutting technology involves fixing the profile with a chuck and then cutting it using a rotary cutting assembly. When the cutting mechanism is cutting heavy materials or pipes with a length greater than 10 meters and a weight of 1 to 3 tons, in order to maintain the stability and accuracy of the cutting, the material to be cut needs to be hoisted onto the cutting machine and kept flat and stable before cutting.

[0003] However, due to the long length and heavy weight of the cutting materials, the process of loading and aligning the cutting materials requires a certain amount of time and labor. Moreover, problems such as a large amount of leftover material are easily generated during the processing, which greatly reduces the work efficiency of cutting heavy materials and heavy pipes.

Then, due to the meshing of the gears, it drives the other rack to move, thereby driving the other sliding plate to move. The clamp 22 is fixedly installed on the sliding plate. The clamp 22 can move left and right with the sliding plate to realize the clamping function. The clamp 22 can extend the entire profile into the rotary cutting assembly 33 to complete the zero tail material cutting.

[0069] like Figure 10 In some specific embodiments, a self-centering clamping assembly 31 is provided on the left side of the drag chain cutting mechanism 3. The self-centering clamping assembly 31 is fixedly connected to the frame 1. The self-centering clamping assembly 31 is provided with an upper clamping roller 311 and a lower clamping roller 312. The upper clamping roller 311 is located above the lower clamping roller 312. The lower clamping roller 312 is fixedly installed on the frame 1. The self-centering clamping assembly 31 is provided with a self-centering drive device 313. The self-centering drive device 313 is connected to the upper clamping roller 311 in a transmission connection. The self-centering drive device 313 can drive the upper clamping roller 311 to move up and down.

[0070] In the self-centering clamping assembly 31, the upper clamping roller 311 and the lower clamping roller 312 are in the same vertical direction. The lower clamping roller 312 is fixed on the frame 1. The upper clamping roller 311 moves up and down relative to the lower clamping roller 312. The upper clamping roller presses the profile or pipe onto the lower clamping roller in the vertical direction, fixing the upper and lower center position of the profile. The left and right directions are maintained by the centering clamping assembly 12 to keep the profile or pipe centered in the front and back directions. The clamping adjustment in the longitudinal and lateral directions forms self-centering, ensuring accurate cutting and adapting to profiles of different specifications. It does not require frequent adjustments and improves work efficiency.

[0071] Furthermore, a transverse clamping component is provided between the self-centering clamping component 31 and the drag chain cutting mechanism 3. The structure of the transverse clamping component is the same as that of the unloading clamping component 41. The transverse clamping component is located on the frame and is used to cooperate with the self-centering clamping component 31.

[0072] like Figure 10-11 In some specific embodiments, a feeding frame 4 is provided on the right side of the drag chain cutting mechanism 3. The feeding frame 4 is provided with a feeding clamping assembly 41 and a feeding roller 42. The feeding clamping assembly 41 includes two feeding clamping rollers 411 and a feeding drive device 412. The feeding drive device 412 is connected to the two feeding clamping rollers 411 respectively. The feeding drive device 412 can drive the two feeding clamping rollers 411 to move back and forth. The feeding roller 42 is a cylinder. Multiple feeding rollers 42 are provided on the feeding frame 4.

[0073] The feeding roller 42 installed on the feeding frame 4 can work in conjunction with the cutting mechanism to achieve seamless connection between cutting and feeding, improve the continuity of the entire production process, avoid the accumulation and interference of cutting materials, ensure the smoothness of production, and help improve efficiency.

[0074] The unloading frame 4 uses multiple steel pipes spliced ​​together to form a rectangular hollow structure, supported by multiple feet below. This saves materials and also provides support for the cut material. The unloading roller 42 and the feeding roller 14 are the same type of mechanism. Multiple unloading rollers 42 are installed on the unloading frame 4, and the cut material can move on the unloading rollers 42, making it convenient to transport the cut material away from the laser cutting machine tool.

[0075] like Figure 11 In some specific embodiments, the cable chain cutting mechanism 3 includes a support frame 32, a rotary cutting assembly 33, and a cable chain winding assembly 34. The rotary cutting assembly 33 is rotatably connected to the support frame 32. The rotary cutting assembly 33 is provided with a laser cutting head 331. The cable chain winding assembly 34 includes a winding device 341, a cable chain 342, and a counterweight device 343. The cable chain 342 includes a head portion 3421 and a tail portion 3422. The head portion 3421 of the cable chain 342 is connected to the rotary cutting assembly 33, and the tail portion 3422 of the cable chain 342 is connected to the counterweight device 343. The cable chain 342 is disposed inside the winding device 341. When the rotary cutting assembly 33 rotates, the head portion 3421 of the cable chain 342 moves downward to release the cable chain 342. When the rotary cutting assembly 33 rotates back, the head portion 3421 of the cable chain 342 moves upward to retract the cable chain 342.

[0076] Rotary cutting can improve cutting efficiency and flexibility. Placing the wires on the rotary cutting assembly 33 into the cable chain 342 can prevent the wires from getting tangled or being dragged, ensuring the normal operation of the rotary cutting assembly 33.

[0077] like Figure 13-14In some specific embodiments, there is another type of feeding rack 13. The feeding rack 13 is provided with a rack plate 135, a rack groove 132, and a feeding drive device 93. The rack plate 135 is provided with a baffle 1351 and a round tube baffle 1352. The baffle 1351 is provided on the front and rear sides of the rack plate 135, and the round tube baffle 1352 is provided on the left and right sides of the rack plate 135. The feeding drive device 93 is located in the rack groove 132. The surface of the rack groove 132 is covered with a dustproof plate 1321. The rack plate 135 and the feeding drive device 93 are connected by a transmission. Next, the first drive device 131 is installed on the back of the material rack groove 132 in an oblique front-back direction. The first drive device 131 is connected to the material rack groove 132 in a transmission connection. The feeding drive device 93 includes a feeding gear 931, two feeding racks 932, and a feeding cylinder 933. One feeding rack 932 is fixedly installed in the material rack groove 132, and the other feeding rack 932 is fixedly installed on the material rack plate 135. The two feeding racks 932 are meshed with the feeding gear 931, and the feeding gear 931 is connected to the feeding cylinder 933 in a transmission connection.

[0078] The design of the material rack plate 135 enhances the stability when feeding round tubes. The surface of the material rack groove 132 is covered with a dustproof plate 1321, which can effectively prevent dust from entering the interior of the material rack groove 132 and keep the feeding environment clean. Moreover, the feeding drive device 93 can drive the material rack plate 135 to generate twice the stroke, thereby improving the transmission efficiency.

[0079] like Figure 13-14 The improvement to the feeding rack 13 lies in the addition of a round tube baffle 1352, a dustproof plate 1321, and a feeding drive device 93. The round tube baffle 1352 can change position along the front and rear direction of the rack plate 135 to accommodate different types of round tubes. The round tube baffle 1352 can hold the round tube in place, making it stationary for easy clamping. This ensures that the centering clamping assembly 12 will not be affected by slight movement of the round tube, thus maintaining its clearance and clamping function. The dustproof plate 1321 is the same size as the opening of the rack groove 132, covering the rack groove 132 to protect its internal structure. The driving end of the feeding cylinder 933 has a connecting block that connects to the feeding gear 931. The material rack plate 135 is slidably connected to a guide rail, the direction of which is the direction of the material rack plate 135 to move back and forth, limiting the driving direction of the feeding cylinder 933. When the material rack plate 135 needs to move back and forth, the feeding cylinder 933 drives the feeding gear 931 to move back and forth on the surface of the feeding rack 932 fixed in the material rack groove 132. When the feeding gear 931 moves back and forth, it will drive the feeding rack 932 on the material rack plate 135 to move, so that the distance it moves is twice that of the feeding gear 931. This allows the material rack plate 135 to achieve twice the stroke of the feeding cylinder 933 driving the feeding gear 931 to move, thereby improving the feeding speed and efficiency of the material rack plate 135.

[0080] The specific operating steps for aligning the feedstock of the laser cutting machine according to this utility model are as follows:

[0081] Before loading, the material rack plate 135 is moved to the rear side of the frame 1. Multiple material rack plates 135 are kept on the same horizontal line and are kept at a height higher than or equal to the height of the clamp 22 and the feeding roller 14 of the feeding assembly 2, so that the profiles to be loaded can be clamped by the clamp 22 on the feeding assembly 2 and placed on the frame 1.

[0082] The centering clamping roller 121 on the centering clamping assembly 12 remains tilted. The feeding assembly 2 moves to the leftmost side of the frame 1. When heavy materials, pipes, and other cutting materials are placed on the material rack plate 135, multiple material rack plates 135 move forward to feed the cutting materials onto the frame 1. Then, the centering clamping roller 121 rotates to an upright position through the avoidance drive device 123. The centering drive device 122 then drives the centering clamping roller 121 to clamp the cutting materials, aligning them. Then, the loading rack 13 moves downward, avoids the cutting materials, and drives the material rack plate 135 to move backward, reaching the position of the material rack plate 135 before loading, ready to load again.

[0083] After the clamp 22 on the feeding assembly 2 clamps the material to be cut, the feeding assembly 2 is driven to move to the right, and works with the self-centering clamping assembly 31 and the drag chain cutting mechanism 3 to clamp and cut. When the feeding assembly 2 moves to the right, the centering clamping roller 121 on the centering clamping assembly 12 closest to the feeding assembly 2 will release the material to be cut, and then rotate from the upright state to the tilting state to avoid the feeding assembly 2, so that the feeding assembly 2 can pass through. When the feeding assembly 2 passes through all the centering clamping assemblies 12 and completes the current cutting task, the feeding assembly 2 moves to the left and returns to the right side of the frame 1 to prepare for the next feeding operation.

[0084] The feeding rack 13, the centering clamping component 12, and the feeding component 2 work together to complete the continuous feeding and alignment tasks.

[0085] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
