Description

Technical Field

[0002] The patent application with application publication number CN115625437B discloses a nickel-plated steel strip laser cutting machine for lithium batteries, including a laser cutting machine table, a matching frame welded on the laser cutting machine table, a limited movable socket provided at the upper end of the matching frame, a cutting support table fixedly provided at the middle position of the upper surface of the laser cutting machine table, a cutting collection groove provided at the middle position of the cutting support table, and when cutting the lithium battery, there is no need for manual operation to fix the lithium battery. During the movement of the gas limit sleeve, the limit movable sleeve will be driven to move under the action of the arc bending rod, and then the lithium battery is automatically fixed under the cooperation of the inner end face of the gas limit sleeve and the limit movable sleeve, which is very convenient and reduces the workload of the staff while also improving the work efficiency of lithium battery cutting.

[0003] In the existing technologies including the above-mentioned patents, during the traditional laser cutting process, the ultra-thin steel strips made of high-temperature alloys are prone to warping and deformation at the cut end due to the heat-affected zone effect, resulting in a decrease in cutting accuracy and an inability to provide a reliable positioning reference for subsequent welding and assembly processes. In addition, the existing cutting equipment cannot flexibly adjust the pressure distribution and texture morphology according to the ultra-thin steel strips of different materials and thicknesses, making it difficult to optimize the thermal deformation control effect. At the same time, high-temperature alloys are prone to slag adhesion and electrostatic adsorption after cutting. Although the traditional air blowing discharge method can remove most of the slag on the ultra-thin steel strips, it may also cause the material to get stuck during lateral movement.

[0019] See also Figure 1-9, the present invention provides a technical solution: a laser heating cutting device for the production of ultra-thin high-temperature alloy steel strips, comprising a base 1, a longitudinal moving device 2 is symmetrically installed on the upper end of the base 1, a transverse moving device 3 is installed on the top of the two longitudinal moving devices 2, a vertical moving device 9 is installed at the front end of the transverse moving device 3, a focusing cutting head 4 is installed on the front side of the vertical moving device 9, and a rejection control mechanism 5 is provided at the lower end of the focusing cutting head 4: the rejection control mechanism 5 includes four pressing plate structures 51, two reset distance adjustment structures 52, four adjustment structures 53 and a symmetrically arranged following structure 54, the pressing plate structure 51 includes a first adjustment plate 511, a second adjustment plate 512, and a third adjustment plate 513, the horizontal surfaces of the first adjustment plate 511, the second adjustment plate 512, and the third adjustment plate 513 are linearly provided with a plurality of through grooves at equal intervals, the through grooves of the first adjustment plate 511, the second adjustment plate 512, and the third adjustment plate 513 are increased in width in sequence, the bottoms of the first adjustment plate 511, the second adjustment plate 512, and the third adjustment plate 513 are in sliding contact, and the first adjustment plate 511, the second adjustment plate 512, and the third adjustment plate 513 are in sliding contact with each other. 12. The top of the third adjustment plate 513 is connected to an adjustment structure 53, which is supported by the base 1. The longitudinal moving device 2 can realize the movement of the top component in the longitudinal direction. The transverse moving device 3 is installed on the top of the longitudinal moving device 2, which can drive the vertical moving device 9 to move transversely. The vertical moving device 9 can move the focused cutting head 4 in the vertical direction, thereby realizing the position adjustment of the focused cutting head 4 in three-dimensional space, so that the focused cutting head 4 can flexibly adjust its position and accurately locate the part to be cut, thereby improving the accuracy and flexibility of cutting. The rejection control mechanism 5 controls the material during the cutting process through the coordinated action of four pressure plate structures 51, two reset adjustment structures 52, four adjustment structures 53 and symmetrical following structure 54, effectively controlling the deformation of the cutting end of the material, ensuring the stability of the cutting process, and by adjusting the pressure plate structure 51, the steel strip expands locally during cutting. The texture morphology of the expanded steel strip is controlled by adjusting the pressure plate structure 51, so that it is suitable for ultra-thin steel strips of different materials and thicknesses, and optimizes the thermal deformation control of laser cutting.

[0020] The adjustment structure 53 includes a limit plate 531, which is slidably connected to the horizontal planes of the first adjustment plate 511, the second adjustment plate 512, and the third adjustment plate 513. The top of the limit plate 531 is connected to the adjustment block 532, and the adjustment block 532 is threadedly connected to three adjustment bolts 533. The three adjustment bolts 533 are rotatably connected to the tops of the first adjustment plate 511, the second adjustment plate 512, and the third adjustment plate 513 respectively. The limit plate 531 is connected to the reset distance adjustment structure 52, and the first adjustment plate 511, the second adjustment plate 512, and the third adjustment plate 513 are respectively controlled by the three adjustment bolts 533. 12.

A reset elastic member 523 is set on the outer ring of the sliding rod 522, and the two spacing blocks 524 are threadedly connected to the two ends of the bidirectional screw 525. One end of the two spacing blocks 524 is connected to a limit plate 531 located at the lower end, and the other end of the spacing block 524 is connected to a following structure 54. The spacing block 524 is slidably connected to the stabilizing rod 6, and the stabilizing rod 6 is connected to the base 1. By rotating the bidirectional screw 525, the two spacing blocks 524 are synchronously moved closer or farther away, thereby adjusting the overall spacing of the pressure plate structures 51 on both sides to make it strictly match the focal width of the laser cutting beam, and the spacing block 524 slides along the stabilizing rod 6 to ensure that there is no offset during the distance adjustment process and maintain the parallelism of the pressure plate structure 51.

[0022] The following structure 54 includes a connecting block 541, one end of which is connected to the longitudinal moving device 2, and two pressure blocks 543 are set on one side of the other end of the connecting block 541, one side of the pressure block 543 is connected to the rubber block 544, and the other side of the pressure block 543 is connected to one end of the symmetrically arranged anti-rotation rod 545, and the other end of the anti-rotation rod 545 is in sliding contact with the connecting block 541, and the other side of the other end of the connecting block 541 is threadedly connected to two pressure bolts 542, and the two pressure bolts 542 are in contact with one pressure block 543 respectively. When the pressure bolts 542 are rotated, the pressure block 543 and the rubber block 544 are pushed inward to resist the spacing block 524, and the anti-rotation rod 545 passes through the pressure block 543 and slides with the connecting block 541 to ensure that the pressure block 543 can only move in a straight line to avoid deflection. The connecting block 541 is fixed on the longitudinal moving device 2, so that the entire following structure 54 moves synchronously with the focused cutting head 4, thereby ensuring that when cutting different positions, there is no need to manually adjust the position and it can directly follow the focused cutting head 4. The lifting mechanism 8 includes a right-angle rod 81, the horizontal end of the right-angle rod 81 is threadedly connected to the pressure-adjusting nut 83, one end of the pressure-adjusting nut 83 away from the vertical end of the right-angle rod 81 contacts one end of the return elastic member 82, the other end of the return elastic member 82 contacts the ground pulley 85, one side of the ground pulley 85 is connected to the hexagonal rod 84, the hexagonal rod 84 is slidably connected to the horizontal end of the right-angle rod 81, the vertical end of the right-angle rod 81 is connected to the top plate 521, the outer ring of the ground pulley 85 contacts the two ends of the lifting roller 88, the two ends of the lifting roller 88 are slidably connected to the reset groove 87 provided on the connecting plate 86, and the connecting plate 86 is connected to a The spacing block 524 is connected. In order to avoid the problem of "material jamming" caused by thermal deformation or slag adhesion, when the cutting is completed, the pressure-adjusting nut 83 drives the return elastic member 82 to push the ground pulley 85 upward, driving the lifting roller 88 to rise from the reset groove 87, and steadily lift the cut steel strip off the work surface. Then the ground pulley 85 is pressurized and retracted from the hexagonal rod 84 to the right-angle rod 81, and finally separated from the lifting roller 88. The lifting roller 88 falls along the reset groove 87 under the action of gravity, thereby resetting. At the same time, the return elastic member 82 can adjust the pressure strength through the pressure-adjusting nut 83 to ensure that the lifting roller 88 can always lift the steel strip.

[0023] An inclined surface is provided between the two horizontally arranged limit plates 531, and the inclined surface contacts the lower end of the focusing cutting head 4. When the rubber 544 applies pressure, a slight offset may occur. At this time, the lower end of the focusing cutting head 4 contacts the inclined surface of the limit plate 531, forming a three-point positioning. During the downward movement of the focusing cutting head 4, if an offset occurs, the guiding effect of the inclined surface will force the reset distance adjustment structure 52, the pressure plate structure 51 and the reset elastic member 523 to return to the original position, and the contact pressure will automatically adjust with the downward movement depth to ensure verticality.
