Description

Technical Field

[0001] The present invention relates to the technology of laser cutting processing of plates, and particularly to a laser cutting device for stainless steel plates. Background Art

[0002] Laser cutting processing is a commonly used material processing method with high precision and high efficiency, which is widely used in the manufacturing of stainless steel products and in multiple industries. When cutting stainless steel plates, due to limitations such as the shape of the parts to be processed, multiple processes are often required, and the required parts and waste materials during the processing need to be collected in different areas. In the Chinese invention patent with the publication number CN115255679A, a high-precision laser cutting device for annular steel plates is disclosed. It performs multiple cuts on square steel plates by setting multiple stepped slide rails and a pusher mechanism, and enables the waste materials after cutting to be utilized. At the same time, the two annular steel plates formed after cutting are respectively located on different main slide rails and are collected by respective material taking mechanisms;

[0003] However, since the circular steel plate formed in the middle after cutting will fall on the platform, its position will shift due to the uncertainty of collision, and there are often certain burrs on the bottom edge of the circular steel plate after cutting. The circular steel plate is not placed flat on the surface of the platform, resulting in difficulty in accurately entering the track when the circular steel plate moves to the next main slide rail. Even if it enters the track, due to the existence of burrs at the bottom, the circular steel plate will not move flat on the track, which will also cause the cutting position to shift during laser cutting, affecting the dimensional accuracy of the annular steel plate. Summary of the Invention

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, it should be noted that, as described in the background technology, the presence of burrs will affect the accuracy of successive processing of steel plates. Existing means generally reserve sufficient tolerances, or perform preliminary grinding of intermediate products after each cutting to remove burrs. However, from the perspective of processing efficiency, preliminary grinding will lead to reduced processing efficiency for the needs of continuous processing, and the grinding of products is also carried out in batches. That is to say, during the cutting process of steel plates, products taken out from different processing positions are collected through continuous processing, which achieves the purpose of classified collection while providing convenience for subsequent deburring processing. Therefore, in order to achieve continuous step-by-step processing, it is difficult to ensure processing efficiency by performing preliminary grinding of burrs during the cutting process. For this purpose, a solution for solving the above-mentioned problem is proposed, and the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] For examples, see Figure 1 - Fig.10 , a stainless steel plate laser cutting device, comprising a first cutting station and a second cutting station, wherein a laser cutting head (not shown in the figure) is arranged on the cutting station for performing circular cutting on the plate, and the stainless steel plate laser cutting device also comprises:

[0037] A bearing mechanism is arranged on the first track 3 and can move along the first track 3 below the first cutting station and the second cutting station. The bearing mechanism includes a bearing platform 1 and a support platform 2. A first opening 11 is provided in the middle of the bearing platform 1 for the support platform 2 to move in a vertical direction. The bottom of the support platform 2 is connected to a first driving member 4. The support platform 2 is circular and the top is parallel to the horizontal plane. The bearing mechanism is connected to a second driving member 5 for driving the movement thereof.

[0038] An auxiliary fixing mechanism is arranged at the second cutting station, and the auxiliary fixing mechanism includes a workbench 6, and a second opening 61 is opened in the middle of the workbench 6. When the supporting mechanism moves to the second cutting station, the central axis of the first opening 11 coincides with the central axis of the second opening 61, and a clamping member 62 is provided on the workbench 6 for fixing and clamping the circular plate 100 in the second opening 61.

[0039] During the cutting process, the original plate is cut at the first cutting station. The original plate includes but is not limited to a square plate. After being cut at the first cutting station, a circular plate 100 and residual material at the edge are formed. The circular plate 100 falls onto the supporting platform 1 of the supporting mechanism below.

[0040] Next, the bearing mechanism is driven by the second driving member 5 to move to the bottom of the second cutting station, and the first driving member 4 drives the support platform 2 to move upward, so that the circular plate 100 located on the bearing platform 1 is moved to the auxiliary fixing mechanism by the support platform 2, wherein the support platform 2 will abut against the position close to the center of the circular plate 100 when moving, thereby avoiding the burr part that may exist on the bottom edge of the cutting part, so that the support platform 2 moves the circular plate 100 to a horizontal state, and finally is moved to the second opening 61 of the workbench 6;

[0041] Finally, the circular plate 100 in a horizontal state is clamped on the workbench 6 by the clamping member 62, and is further cut by laser cutting at the second cutting station to form a circular plate and a small circular plate 100 in the middle;

[0042] It should be noted that a third cutting station, another auxiliary fixing mechanism and another supporting mechanism can also be set up to further process the formed small circular plate 100 in the same way as described above, which will not be described in detail here; in addition, for the supporting platform 1, the diameter of the first opening 11 thereon is smaller than the diameter of the circular plate 100 to be carried, and for the workbench 6, the diameter of the second opening 61 thereon is larger than the diameter of the circular plate 100 to be fixed.

[0043] In one embodiment of the present invention, the second driving member 5 is a general linear moving mechanism, which is a prior art and will not be described in detail herein, and the specific structure is not shown in the figure.

[0044] In one embodiment of the present invention, a centering component 7 is disposed on the carrier platform 1 , which includes four positioning rods 71 ​​distributed in a circular array, and the four positioning rods 71 ​​can move synchronously along the radial direction of the first opening 11 to approach or move away from the center of the carrier platform 1 .

[0045] In one embodiment of the present invention, the centering component 7 includes a first driving ring 72, on which an inclined first slide groove 73 is opened, four second slide grooves 74 are opened on the bearing platform 1 along the radial direction of the first opening 11, a first slide 75 is slidably connected in the second slide groove 74, a guide rod 76 is fixedly connected to the bottom of the first slide 75, and the top of the first slide 75 is fixedly connected to the positioning rod 71, the first driving ring 72 is rotatably connected to the inner wall of the bearing platform 1, and the first driving ring 72 is connected to the A driving member 77 for driving it to rotate around the central axis of the first opening 11;

[0046] In one embodiment of the present invention, a specific example of the A driving member 77 is provided (not shown in the figure), which includes a first motor, one end of the output shaft of the first motor is fixedly connected to the first gear, the first gear is meshed with the first annular rack arranged on the outer circumference or the inner circumference of the first driving ring 72, the first motor is fixedly installed on one side of the supporting platform 1, and the first motor drives the first gear to rotate and drives the annular rack to rotate, thereby driving the first driving ring 72;

[0047] When the first driving ring 72 rotates, the first slide groove 73 and the second slide groove 74 cooperate to drive the guide rods 76 to move, so that the first slide 75 is close to or away from the center of the supporting platform 1, thereby moving through the positioning rods 71 ​​and pushing the circular plate 100 on the supporting platform 1 to the center of the supporting platform 1, that is, in a state of being coaxial with the first opening 11. It should be noted that before the support platform 2 pushes the circular plate 100 to move to the second opening 61, the positioning rods 71 ​​are away from the circular plate 100 so that it can be in a movable state.

[0048] In one embodiment of the present invention, a specific example of a first driving member 4 is provided (not shown in the figure), which is a cylinder or a hydraulic cylinder or an electric telescopic rod, and the piston rod of the cylinder or the piston rod of the hydraulic cylinder or the telescopic rod of the electric telescopic rod is connected to the bottom center of the support platform 2.

[0049] Due to the presence of burrs at the bottom edge of the circular plate 100 after cutting at the first cutting station, it is not in close contact with the surface of the carrying platform 1 after falling on the carrying platform 1, and since the length of the burrs is uncontrollable and has a certain randomness, when the circular plate 100 falls on the carrying platform 1, it generally tilts. At this time, moving the circular plate 100 by the centering component 7 first does not make the circular plate 100 and the first opening 11 in a coaxial position, such as Fig.10As shown, the position accuracy of the circular plate 100 when the subsequent support 2 moves the circular plate 100 to the second opening 61 is affected. Here, a method for solving the above problem is provided. After the support 2 moves in the vertical direction until the circular plate 100 has a first gap with the surface of the carrier 1, the four positioning rods 71 ​​move toward the center direction of the carrier 1 to the maximum stroke and then move away from each other. It should be noted that the size of the first gap is based on the longest burr at the bottom of the circular plate 100 not contacting the surface of the carrier 1. At this time, the circular plate 100 only contacts the surface of the support 2, so that the circular plate 100 is in a horizontal state under the support of the support 2, and then the centering component 7 acts on the circular plate 100 to make it move in a horizontal state on the top of the support 2, completing the position adjustment of the circular plate 100, and finally the support 2 continues to rise to move the circular plate 100 into the second opening 61 for fixing;

[0050] In order to achieve the above method, the first driving member 4 first drives the support platform 2 to move, and then the A driving member 77 drives the four positioning rods 71 ​​to move, so that the four positioning rods 71 ​​first move toward the center of the first opening 11, and the circular plate 100 moves to the center position (the four positioning rods 71 ​​move synchronously until they are all pressed against the sides of the circular plate 100), and then the A driving member 77 drives the four positioning rods 71 ​​away from each other, and finally the first driving member 4 continues to drive the support platform 2 to rise.

[0051] In one embodiment of the present invention, another specific example of the first driving member 4 is provided, which includes a rotating drum 41, which is in a stepped shape and has a first portion 411, a second portion 412, a third portion 413, a fourth portion 414 and a fifth portion 415 connected in sequence, wherein the first portion 411, the third portion 413 and the fifth portion 415 are horizontal and have increasing heights, and the second portion 412 and the fourth portion 414 are inclined, such as Figure 5 As shown, the rotating drum 41 is rotatably mounted on the second slide 42, the second slide 42 is slidably connected to the first track 3, and the top of the second slide 42 is fixedly connected to the bearing platform 1 through a support column 43.

[0052] A first rod 44 is fixedly connected to the bottom of the support 2, a support 45 is slidably connected to the surface of the first rod 44, the support 45 is fixedly connected to the support column 43 through a first bracket 46, the bottom of the first rod 44 is slidably connected to the top of the rotating drum 41, and the bottom of the rotating drum 41 is connected to a second motor 47 for driving it to rotate;

[0053] It should be noted that, in order to save space, the second motor 47 can also be arranged on the second slide 42, such as Figure 4As shown, the bottom of the rotating drum 41 is fixedly connected to a rotating shaft, which passes through the second slide 42 and is rotatably connected to the second slide 42. The rotating shaft and the output shaft of the second motor 47 are both equipped with a transmission wheel and are connected through a transmission belt (not shown in the figure);

[0054] By rotating the drum 41, the first rod body 44 is rotated on the first part 411, the second part 412, the third part 413, the fourth part 414 and the fifth part 415 of the drum 41. Specifically, when the first part 411 is rotated, the first rod body 44 is located at the lowest position, and the support platform 2 is also at the lowest position. When the first rod body 44 is rotated to the third part 413, the support platform 2 is located at a position where there is a first gap between the circular plate 100 and the surface of the supporting platform 1. When the first rod body 44 is rotated to the fifth part 415, the support platform 2 moves the circular plate 100 to the second opening 61.

[0055] In one embodiment of the present invention, another specific example of A driving member 77 is provided, which is different from the above-mentioned rotating drum 41. Specifically, A driving member 77 includes a second rod body 7701, the inner wall of the second rod body 7701 is rotatably connected to the surface of the first rod body 44, the lower end of the second rod body 7701 is fixedly connected to a second gear 7702, the top of the second rod body 7701 is fixedly connected to a turntable 7703, and at least one first push block 7704 is installed on the circumference of the turntable 7703. In this embodiment, two first push blocks 7704 are arranged to improve stability, a ring body 7705 is rotatably installed in the support platform 1, a second push block 7706 is installed on the inner side of the ring body 7705, and a third slide groove for the second push block 7706 to move is opened on the inner side of the support platform 1. Two third push blocks 7707 are installed on the outer side of the first driving ring 72, and a fourth push block 7708 is fixedly connected to the inner side of the first driving ring 72. The fourth push block 7708 is located between the two third push blocks 7707, and the same arc-shaped guide rod 7709 is fixedly installed on the two third push blocks 7707. The arc-shaped guide rods 7709 located on both sides of the fourth push block 7708 are sleeved with first springs 7710. The A driving member 77 also includes a driving disk 7711, and the driving disk 7711 is provided with an arc-shaped rack 7712. When the end of the first rod body 44 moves in the third part 413, the arc-shaped rack 7712 is meshed with the second gear 7702. When the end of the first rod body 44 moves in the third part 413, the second push block 7706 is located on the moving path of the first push block 7704, as shown in FIG. Figure 4 and Figure 5As shown, at this time, the rotation of the rotating drum 41 drives the arc-shaped rack 7712 to rotate, and then drives the turntable 7703 to rotate through the second gear 7702. When the turntable 7703 rotates, the second push block 7706 is pushed by the first push block 7704, so that the ring body 7705 rotates. When the ring body 7705 rotates, the first spring 7710 is compressed and drives the fourth push block 7708 to move, so that the first drive ring 72 rotates. During the movement of the end of the first rod body 44 along the fourth part 414 to the fifth part 415, the arc-shaped rack 7712 is disengaged from the second gear 7702, and the first push block 7704 is staggered and separated from the second push block 7706. Thereafter, the first spring 7710 is released from compression, so that the ring body 7705 rotates in the opposite direction for a certain distance, which is greater than the width of the first push block 7704. When the support platform 2 moves downward, the first drive ring 72 is reset. It should be noted that at this time, the surface of the second rod body 7701 is slidably connected to the support 45.

[0056] In one embodiment of the present invention, the clamping member 62 includes four chucks 621 arranged on the workbench 6 and distributed in a circular array, a first swing rod 622 is connected to one side of the chuck 621, an inner wall of one end of the first swing rod 622 is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected to the inner wall of the workbench 6, a second swing rod 623 is connected to the lower end of the rotating shaft, a tray 624 is fixedly installed at the end of the second swing rod 623, each rotating shaft is connected to a B driving member for driving it to rotate around its own central axis, and the rotating shaft has a first state and a second state when rotating, in the first state, the chuck 621 and the tray 624 are both located outside the first opening 11 of the workbench 6, in the second state, the chuck 621 and the tray 624 move to the first opening 11, and a first accommodating cavity 605 for accommodating the first swing rod 622 and the chuck 621, and a second accommodating cavity 626 for accommodating the second swing rod 623 and the tray 624 are opened on the workbench 6;

[0057] It should be noted that the length of the second rocker arm 623 is greater than that of the first rocker arm 622. In the second state, the chuck 621 is pressed against the peripheral side of the circular plate 100, and the tray 624 is located at the bottom of the circular plate 100. It should be understood that the first rocker arm 622 and the second rocker arm 623 have an angle α in the vertical direction, and a hard rubber sheet can also be installed on the side where the chuck 621 contacts the circular plate 100.

[0058] In one embodiment of the present invention, the B driving member includes a second driving ring 627 rotatably mounted inside the workbench 6, a fourth gear 628 is fixedly mounted on the top of the rotating shaft, the B driving member also includes a third motor fixedly mounted on one side of the workbench 6, a fifth gear 629 is fixedly mounted on one end of the output shaft of the third motor, and an arc-shaped tooth portion is provided on the outer side of the second driving ring 627, which is respectively meshed with the fifth gear 629 and each fourth gear 628.

[0059] Since the size of the angle α between the first swing arm 622 and the second swing arm 623 determines the position of the chuck 621 when clamping the circular plate 100 and the supporting position of the tray 624, the angle needs to be adaptively adjusted for the annular plates of different diameters. Although the appropriate angle can be obtained by replacing the chuck 621 matching the annular plates of different diameters, the operation is often complicated and cumbersome. Therefore, a method for solving this problem is provided. Specifically, an angle adjustment device 8 is provided between the first swing arm 622 and the second swing arm 623;

[0060] In one embodiment of the present invention, the rotating shaft is composed of a first shaft 81 and a second shaft 82, the first shaft 81 is connected to the first swing rod 622, the second shaft 82 is connected to the second swing rod 623 and is sleeved on the first shaft 81, the bottom of the second shaft 82 is fixedly connected to a first face gear 83, the lower end of the first shaft 81 is slidably connected to a second face gear 84, and the teeth of the first face gear 83 and the second face gear 84 are opposite, and a second spring 85 is arranged between the bottom of the first shaft 81 and the second face gear 84;

[0061] When in use, the second face gear 84 is moved to disengage it from the first face gear 83, and then the second rocker arm 623 can be rotated to adjust the angle α. After adjustment, the second face gear 84 is released and meshed and locked with the first face gear 83 again under the action of the second spring 85, so that the angle between the first rocker arm 622 and the second rocker arm 623 is locked.

[0062] In one embodiment of the present invention, the workbench 6 may be fixed or movable. Figure 1 As shown, a second track 63 may be provided. When the circular plate 100 on the workbench 6 is cut, the workbench 6 carrying the circular plate is moved along the second track 63 to the outside of the second cutting station for unloading.

[0063] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present invention.
