Description

Technical Field

[0001] The invention relates to the field of metal sheet production and processing, and in particular to laser cutting equipment for metal sheet production and processing. Background Art

[0002] Laser cutting technology has many significant advantages that have led to its widespread use in a variety of industrial and manufacturing fields. The following are the main benefits of laser cutting. Laser cutting can achieve very high positioning accuracy and repeatability, which enables it to cut complex shapes and tiny details. Because the laser beam is focused into a very small spot of light, a high power density is achieved at the focus, and the material is quickly heated to the point of vaporization, forming a narrow slit. The incision surface is smooth and burr-free, and no post-processing is required. The laser cutting speed is extremely fast. For example, with a 2KW laser power, the cutting speed of 8mm thick carbon steel is 1.6m / min; the cutting speed of 2mm thick steel is 3.5m / min, which greatly improves production efficiency. The heat-affected zone generated during laser cutting is very small, and the deformation of the workpiece is minimal, thus ensuring the stability of material properties and cutting quality. Laser cutting is pollution-free and has low noise, which greatly improves the working environment of the operator. At the same time, due to its high precision and low heat-affected zone, the operation is safer. Laser cutting not only reduces material waste, but also reduces maintenance and processing costs, especially in mass production. Laser cutting technology, with its advantages of high precision, high speed, high quality and wide material compatibility, occupies an important position in modern manufacturing and continues to promote technological progress and development in related industries. Existing laser cutting equipment for metal sheet production and processing cannot dissipate heat from the metal sheet after cutting, which may cause burns to workers. Summary of the invention

[0012] The present invention provides a laser cutting device for producing and processing metal sheets. It has the following beneficial effects: 1) The laser cutting equipment for producing and processing metal sheets is provided with a rotating fixing device and a dust removal device. The staff places the metal sheet to be cut on the placing plate, and then starts the rotating motor to drive the working disk to rotate. At the same time, the staff starts the third cylinder and the fourth cylinder at the same time.

[0013] 2) The laser cutting equipment for producing and processing metal sheets is provided with a detection switching device. Then the staff starts the first cylinder to drive the detection box to move downward, and the detection box drives the detection plate to move downward synchronously. When the detection plate contacts the metal sheet so that the downward movement is restricted, the detection box continues to be controlled to move downward, and the detection plate will not be driven to move downward, so that the detection box can be driven to move downward until it contacts the placement plate and then controls the detection box to move upward.

Otherwise, it needs to be replaced.

[0014] 3) The laser cutting equipment for the production and processing of the metal sheet is provided with a three-dimensional adjustment device. Then the staff controls the high-power laser cutter or the low-power laser cutter to start, and then starts the three-dimensional adjustment device. By starting the second cylinder, the lifting frame is controlled to rise and fall. Then the adjustment motor is started. The rotation of the adjustment motor drives the first screw to rotate, thereby controlling the forward and backward movement of the sliding base and the lifting frame. The driving motor drives the second screw to rotate, controlling the left and right translation of the translation seat, thereby controlling the three-dimensional movement of the laser cutter, and realizing the automatic cutting of the metal sheet.

[0015] 4) The laser cutting equipment for producing and processing metal sheets is provided with a water cooling mechanism. When the cutting is completed, the rotating motor is started to rotate the working disk, and then the staff starts the servo motor. The rotation of the servo motor drives the driving shaft to rotate, and the driving shaft drives the half gear to rotate. When the half gear is engaged with the second rack, the half gear drives the second rack to move, and the second rack drives the moving rod to move, and the moving rod drives the piston rod to move, so that the space of the sealing cavity formed by the piston rod and the sleeve is reduced, so that the water in the sleeve is squeezed into the water outlet pipe, and then flows into the fixed pipe, and finally sprayed to the metal sheet by the nozzle. The water absorbs the heat on the metal surface, thereby realizing water cooling and heat dissipation, and improving the cooling efficiency of the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

The rotation of the servo motor 118 drives the driving shaft 116 to rotate, and the driving shaft 116 drives the half gear 113 to rotate. When the half gear 113 is engaged with the second rack 114, the half gear 113 drives the second rack 114 to move, and the second rack 114 drives the moving rod 115 to move. The moving rod 115 drives the piston rod 120 to move, so that the space of the sealed cavity formed by the piston rod 120 and the sleeve 129 is reduced, so that the water in the sleeve 129 is squeezed into the water outlet pipe 123, and then flows into the fixed pipe 124, and finally sprayed to the metal sheet by the nozzle 125. The water absorbs the heat on the metal surface, thereby realizing water cooling and heat dissipation, and improving the cooling efficiency of the workpiece. ;
