Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting processing, and particularly to a laser cutting device for high-strength corrosion-resistant stainless steel composite materials. Background Art

[0002] The existing laser cutting technology has been widely used in the metal processing industry, especially for cutting metal materials such as stainless steel, aluminum alloy, and iron plate. When traditional laser cutting equipment performs cutting operations, it usually needs to use fixtures to fix the materials. Using fixtures requires additional time and manual operations, which not only increases the production preparation time but also reduces the overall production efficiency. During the laser cutting process, the metal material rapidly melts under the high-temperature laser irradiation, generating a large amount of cutting smoke and powder. If these smoke and powder are not removed in a timely and effective manner, they are likely to accumulate on the cutting surface, affecting the cutting quality. The accumulated powder may interfere with the transmission of the laser beam, resulting in an uneven cutting edge or even an incomplete cutting effect. Most traditional laser cutting equipment adopts manual or semi-automatic operations for pallet reset and material pushing. For example, the pallet needs to be manually adjusted and reset, and the material feeding also requires manual intervention. This process significantly reduces the production efficiency and increases the labor cost. Especially in large-scale production, frequent manual adjustments by operators not only increase the workload but also increase the probability of human errors. In addition, the lack of automatic control means that the same operations need to be repeated during each cutting process, and the automation technology cannot be fully utilized to improve efficiency and reduce labor intensity.

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-7 , and further illustrate the technical solution of the present invention through specific implementation methods.

[0020] The present invention provides a laser cutting device for a high-strength corrosion-resistant stainless steel composite material, including a support rotating disk 123, on which a plurality of discharge ports 124 arranged in a circular array are provided, and a positioning plate 125 is fixed to one side of each discharge port 124 away from the center of the support rotating disk 123; an outer transmission ring 109 is fixed at the circumferential position of the upper surface of the support rotating disk 123, a laser head displacement frame 126 is installed on the outer transmission ring 109, and a laser head 127 is installed on the laser head displacement frame 126, which is used to drive the laser head 127 to move in two degrees of freedom on the horizontal plane; a rectangular table block 122 is fixedly installed at the central position of the support rotating disk 123, a central sliding rod 121 is fixed at the center of the rectangular table block 122, a counterweight block 118 is slidably arranged on the central sliding rod 121, the rectangular table block 122 has a plurality of side edges, and two parallel guiding and supporting sliding rods 130 are fixedly installed on each side edge, a tray 128 is sleeved on each two guiding and supporting sliding rods 130, a push bar 120 is slidably arranged on the tray 128, and the push bar 120 is movably connected to the counterweight block 118 through a movable connecting rod 119. Two guiding rails 129 are provided on the guiding and supporting sliding rods 130, and the push bar 120 is slidably arranged on the guiding rails 129. A limiting push block 131 is fixedly arranged on the side of the guiding and supporting sliding rods 130 close to the center of the support rotating disk 123, which is used to limit the moving position of the push bar 120 on the tray 128. The number of the trays 128 is the same as that of the discharge ports 124, and the trays 128 are aligned with the discharge ports 124, and the wide sides of the trays 128 and the discharge ports 124 are parallel; a reset tension spring 106 is wound around each guiding and supporting sliding rod 130, and both ends of the reset tension spring 106 are fixedly cooperated with the rectangular table block 122 and the tray 128. A magnetic suction sleeve disk 114 is rotatably arranged on the upper surface of the counterweight block 118, a paddle support rotating sleeve 115 is rotatably sleeved on the circumferential surface of the counterweight block 118, and a paddle 116 is fixed on the circumferential surface of the paddle support rotating sleeve 115; a spline sleeve shaft 117 is coaxially fixed at the central position of the upper surface of the magnetic suction sleeve disk 114, and both the magnetic suction sleeve disk 114 and the spline sleeve shaft 117 are rotatably sleeved on the central sliding rod 121. The support rotating disk 123 is rotatably installed on the upper surface of the rotating disk surface 103, a transmission shaft column 108 is also rotatably arranged on the rotating disk surface 103, and an arched magnetic frame 107 is also fixedly arranged on the rotating disk surface 103, wherein the spline sleeve shaft 117 passes through the arched magnetic frame 107, and the arched magnetic frame 107 and the spline sleeve shaft 117 are rotatably cooperated, and the magnetic suction sleeve disk 114 and the arched magnetic frame 107 are magnetically cooperated; a spline pulley 113 is rotatably installed on the upper surface of the arched magnetic frame 107 through a spline pulley bracket 112, and the spline pulley 113 is sleeved on the outer surface of the spline sleeve shaft 117 in a spline sliding manner.The top end of the drive shaft column 108 is drivingly connected to the spline pulley 113 through the second drive belt 110, and the bottom end of the drive shaft column 108 is drivingly connected to the outer drive ring 109 through the third drive belt 111. The rotating disk surface 103 is fixed above the support plate 101 through a plurality of spaced brackets 102; a drive motor 104 is also fixedly installed on the support plate 101, and a central drive rotating shaft 132 is fixedly installed at the center position of the lower surface of the support rotating disk 123. The central drive rotating shaft 132 is rotationally matched with the support plate 101, and the output shaft of the drive motor 104 is drivingly connected to the central drive rotating shaft 132 through the first drive belt 105.

[0021] The working principle of a laser cutting device for a high-strength corrosion-resistant stainless steel composite material disclosed by the present invention is as follows: Place the stainless steel plate on the tray 128 (it is necessary to place it on each tray 128), and then start the drive motor 104. The output shaft of the drive motor 104 drives the central drive rotating shaft 132 to rotate through the first transmission belt 105. The central drive rotating shaft 132 drives the support rotating disk 123 to rotate. The rotation of the support rotating disk 123 will drive all the components on the support rotating disk 123 to rotate together, including the tray 128 and the stainless steel plate on the tray 128. Under the action of centrifugal force, the tray 128 will slide on the guiding support sliding rod 130, and at the same time, the reset tension spring 106 will be stretched. At the same time, the push bar 120 will also move along with it under the action of centrifugal force (since the push bar 120 and the guiding slide rail 129 are in sliding fit, there is friction in the actual process, so the limit push block 131 is set, and the limit push block 131 will push the push bar 120 to move along with the tray 128). At the same time, the stainless steel plate will also contact the positioning plate 125 under the action of centrifugal force and be supported by the lower tray 128 (the rotation speed process is slowly increasing). At this time, one side of the stainless steel plate will be closely attached to the positioning plate 125 to achieve unilateral positioning. Then, start the laser head 127 and the laser head displacement frame 126 to cut the stainless steel plate. The powder generated during the cutting process will be thrown out under the action of centrifugal force (a cover is set outside) to prevent the powder from accumulating on the stainless steel plate. When the cutting is completed, slowly stop the drive motor 104 (the laser head 127 and the laser head displacement frame 126 will also stop), and then the support rotating disk 123 will also slowly stop rotating. During this process, the tray 128 will reset under the action of the reset tension spring 106; the push bar 120 will not reset because when the push bar 120 moves to a position far from the rectangular table block 122, it will drag the counterweight 118 to move downward through the movable connecting rod 119, so that the magnetic attraction sleeve disk 114 is separated from the arched magnetic frame 107. Then, the counterweight 118 moves to the lowest point of the central sliding rod 121 and restricts the push bar 120 under the action of gravity. Therefore, when the tray 128 resets, relative sliding occurs between the push bar 120 and the tray 128, and the push bar 120 is used to push the stainless steel plate off the tray 128 and then it falls through the discharge port 124.When used next time, the push bar 120 can be manually pushed to make the magnetic suction sleeve disc 114 attracted to the arched magnetic frame 107 again, or the drive motor 104 can be controlled in the reverse direction, and then the support rotating disc 123 can be rotated in the reverse direction. The rotation of the support rotating disc 123 will drive the transmission shaft column 108 to rotate through the third transmission belt 111. The transmission shaft column 108 drives the spline pulley 113 to rotate through the second transmission belt 110. The spline pulley 113 drives the spline sleeve shaft 117 to rotate. The spline sleeve shaft 117 drives the magnetic suction sleeve disc 114, the blade support rotating sleeve 115, and the blade 116 to rotate. The reverse rotation of the blade 116 will generate an upward lift force, thereby pulling the counterweight 118 upward, causing the counterweight 118 and all the push bars 120 to return to their original positions (where the counterweight 118 and the blade support rotating sleeve 115 can only rotate circumferentially and cannot move axially).
