Description

Technical Field

[0001] The invention relates to the technical field of laser cutting equipment, and in particular to a sheet metal laser cutting device with adjustable angle. Background Art

[0002] Laser cutting is to use a focusing mirror to focus a CO2 laser beam on the surface of the material to melt the material, and at the same time use compressed gas coaxial with the laser beam to blow away the melted material, and make the laser beam and the material move relative to each other along a certain trajectory, thereby forming a slit of a certain shape. Laser cutting technology is widely used in the processing of metal and non-metallic materials. Sheet metal has the characteristics of light weight, high strength, conductivity, low cost, and good performance in large-scale mass production. It has been widely used in the fields of electronics, communications, automotive technology, medical equipment, etc. With the increasing application of sheet metal, the processing of sheet metal parts is an important part of the product manufacturing process. When cutting sheet metal parts, a laser cutting device is required for cutting.

[0003] Announcement No. CN 210755830 U discloses a laser cutting tool with adjustable cutting angle. The object to be cut is placed on the upper surface of the mounting plate, and the bolt is rotated. The bolt rotates on the end baffle plate and drives the internal baffle plates on both sides to clamp the two sides of the object to be cut. Through this setting, the cutting piece is effectively prevented from slipping during the turning process of the object to be cut. After clamping, the box door on the cutting box is opened, the output shaft of the first motor drives the gear to rotate, the gear meshing drives the rack to move horizontally, and the rack drives the feed plate to slide on the upper surface of the horizontal rail through the slider, and the feed plate enters the cutting box, and the box door is closed. Through the setting of the box door, the laser cutting process is effectively prevented. The generated smoke is directly discharged to the outside air. The output end of the rotating cylinder drives the rotating plate to rotate. The two rotating plates cooperate to drive the mounting plate to rotate. The mounting plate drives the cutting object fixed on the upper surface to flip, thereby adjusting the cutting angle. Through this setting, the adjustment of different cutting angles can be completed without adjusting the cutting angle of the laser cutting head. The output end of the second motor drives the screw to rotate. The screw cooperates with the outer peripheral nut to drive the translation block to slide along the horizontal direction of the slide groove, thereby adjusting the cutting position of the cutting head. Through this setting, the cutting of different positions of the cutting object can be met. However, the following problems still exist in the actual use of this patent:

[0004] Although the laser cutting tool with adjustable cutting angle can drive the rotating plate to rotate by rotating the output end of the rotating cylinder, and the two rotating plates cooperate to drive the mounting plate to rotate, and the mounting plate drives the cutting object fixed on the upper surface to flip, thereby adjusting the cutting angle, when the sheet metal needs to be cut with a certain arc, the laser cutting tool with adjustable cutting angle cannot cut the corresponding arc. At the same time, when cutting the arc, since the arc has size and length, the size and length of the arc cannot be accurately controlled, thereby affecting the cutting effect of the arc.

[0005] Therefore, a sheet metal laser cutting device with adjustable angle is proposed to solve the above-mentioned problems. Summary of the invention

When the sheet metal needs to be cut with a certain arc, the laser cutting tool with adjustable cutting angle cannot cut the corresponding arc.

[0044] Secondly, the smoke and harmful gases generated by the laser cutting equipment 131 during cutting are sucked into the purification box 135 through the connecting pipe 134 by the vacuum cleaner 133 inside the exhaust gas collection cover 132. The purification box 135 is provided with a solution for purifying the smoke and harmful gases. The mixing motor 136 drives the stirring rod 137 to rotate, so that the solution can be fully stirred, so that the solution can fully react with the smoke and harmful gases, thereby purifying the smoke and harmful gases. The bidirectional motor 139 drives the lifting and rotating rod 140 and the bevel gear transmission assembly 141 to rotate. At the same time, the bevel gear transmission assembly 141 drives the lifting and rotating rod 142 to rotate, so that the lifting and rotating threaded sleeve 143 drives the translation bracket 144 to lift and move. The translation motor 145 drives the first sprocket transmission assembly 146 and the translation threaded rod 147 to rotate, so that the translation threaded sleeve 148 drives the fixed rotating disk 101 to move horizontally, thereby realizing the height and horizontal adjustment of the laser cutting equipment 131, which is convenient for cutting sheet metal parts.

[0045] Finally, the longitudinal motor 204 is used to drive the second sprocket transmission assembly 205 and the longitudinal threaded rod 206 to rotate, so that the longitudinal threaded sleeve 207 drives the lifting bracket 138 to move longitudinally. By cooperating with the bidirectional motor 139 and the translation motor 145, the laser cutting equipment 131 can be moved in all directions, thereby improving the effect of laser cutting of sheet metal parts. The support plate 208 and the triangular support block 209 can support the protective pad 210, and the protective pad 210 can buffer and prevent the sheet metal parts from slipping, thereby protecting the sheet metal parts and improving the effect of laser cutting. There is a gap between the support plates 208, so the debris generated during cutting can fall into the dust box 201. The cleaning push plate 215 drives the cleaning sliding rod 214 and the lifting bevel block 216 to move. By utilizing the sliding connection between the lifting bevel block 216 and the lifting bevel plate 217, the lifting bevel plate 217 can drive the cleaning brush 218 to move up and down, thereby cleaning the support plates 208 and the triangular support blocks 209. The debris and dust are guided to the drain port 213 through the inclined plate 212 inside the dust box 201, which is convenient for collecting the debris generated by cutting.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
