[0037] Example 1
[0038] When cutting a bevel on a workpiece using a laser cutting device, the laser and cutting gas pass through the workpiece at a length greater than the thickness of the workpiece because the laser and cutting gas form an angle with respect to the workpiece. When cutting a bevel, the distance between the gas outlet end of the nozzle and the workpiece is greater than when cutting a straight line because there is an angle between the gas outlet end of the nozzle and the workpiece. An increase in the distance between the gas outlet end of the nozzle and the workpiece can cause the cutting gas to escape on the surface of the workpiece, thereby reducing the amount of cutting gas entering the kerf.
[0039] A reduction in the amount of cutting gas entering the kerf can cause problems such as uneven cutting surfaces, i.e., layering of the cutting surface, and slag sticking to the bottom of the workpiece. Therefore, the present embodiment provides a laser cutting nozzle structure for cutting a bevel that can increase the amount of cutting gas entering the kerf of the workpiece when cutting a bevel, thereby solving problems such as layering of the cutting surface and slag sticking to the bottom of the workpiece when cutting a bevel.
[0040] Specifically, as shown in Figures 1 to 3 the laser cutting nozzle structure for cutting a bevel includes a nozzle 100, a sleeve 200, and a connecting assembly 300. The nozzle 100 is configured to deliver cutting gas, the axis of the sleeve 200 is configured to be perpendicular to the workpiece 10, the gas outlet end 110 of the nozzle 100 is located within the sleeve 200, and along the axial direction of the sleeve 200, one end of the sleeve 200 is a first end 210, the first end 210 is configured to point towards the workpiece 10, and the cutting gas ejected from the gas outlet end 110 can be collected between the first end 210 and the workpiece 10. The connecting assembly 300 is connected to the sleeve 200, one of the connecting assembly 300 and the nozzle 100 is provided with a spherical outer wall 410, and the other is provided with a spherical cavity 420. The spherical outer wall 410 is shaped to match the shape of the spherical cavity 420, and the spherical outer wall 410 is rotatably embedded in the spherical cavity 420.
[0041] Based on the above design, one of the connecting assembly 300 and the nozzle 100 is provided with a spherical outer wall 410, and the other is provided with a spherical cavity 420. The spherical outer wall 410 is rotatably embedded in the spherical cavity 420, so the nozzle 100 can tilt relative to the connecting assembly 300. The connecting assembly 300 is connected to the sleeve 200, and the axis of the sleeve 200 is configured to be perpendicular to the workpiece 10. Therefore, when cutting, tilting the nozzle 100 so that the nozzle 100 is inclined relative to the workpiece 10 can cut a bevel on the workpiece 10, Figure 3The structure diagram of the nozzle 100 is shown when the nozzle 100 is inclined by 30° relative to the workpiece 10 to be cut, and the workpiece 10 to be cut can be bevel cut. On this basis, the connecting assembly 300 is connected with the sleeve 200, and the gas outlet end 110 of the nozzle 100 is located in the sleeve 200. The cutting gas sprayed from the gas outlet end 110 can be gathered between the first end 210 and the workpiece 10 to be cut, thereby reducing the probability of the cutting gas escaping on the workpiece 10 to be cut, increasing the gas inlet amount of the cutting gas into the cutting seam of the workpiece 10 to be cut, improving the deslagging effect, solving the problem of slag hanging at the bottom of the cutting seam of the workpiece 10 to be cut during bevel cutting, and increasing the gas inlet amount of the cutting gas into the cutting seam of the workpiece 10 to be cut, which can improve the flatness of the cutting cross section of the workpiece 10 to be cut, and further reduce the probability of the cutting cross section being layered during bevel cutting.
[0042] Further, the nozzle 100 comprises a nozzle body 120 and a matching ring 130, the matching ring 130 is sleeved on the nozzle body 120, the outer wall of the matching ring 130 is a spherical outer wall 410, and a spherical cavity 420 is arranged on the connecting assembly 300. The structure design is simple, and the matching ring 130 only needs to be sleeved on the outside of the existing nozzle body 120 to manufacture the nozzle 100, that is, the structural improvement of the nozzle body 120 is omitted, which is beneficial to reduce the production difficulty of the laser cutting nozzle structure for cutting bevels.
[0043] In the embodiment, the nozzle body 120 and the matching ring 130 are threadedly connected, of course, in other embodiments, the nozzle body 120 and the matching ring 130 can also be connected through bolts or the like connecting members, or through colloid adhesion.
[0044] Optionally, the outer wall of the sleeve 200 is provided with a convex eave 260, the convex eave 260 extends along the circumference of the sleeve 200 and is connected end to end, the convex eave 260 is located at the first end 210, the side of the convex eave 260 facing the cut workpiece 10 is a slope surface 261, in the direction away from the axis of the sleeve 200, the slope surface 261 is inclined in the direction away from the cut workpiece 10, in the axial direction of the sleeve 200, the sleeve 200 is movably connected with the connecting assembly 300. During the cutting operation, the cutting gas sprayed out of the nozzle 100 gas outlet 110 first enters the sleeve 200, and then the first end 210 of the sleeve 200 sprays the cutting gas onto the surface of the cut workpiece 10, and the surface of the cut workpiece 10 reflects the cutting gas onto the slope surface 261 of the convex eave 260. For simplicity of description, the force exerted by the cutting gas on the slope surface 261 will be referred to as the jacking force, and the force exerted by the atmospheric pressure on the side of the convex eave 260 away from the cut workpiece 10 will be referred to as the atmospheric pressure. Since the side of the convex eave 260 facing the cut workpiece 10 is a slope surface 261, and in the direction away from the axis of the sleeve 200, the slope surface 261 is inclined in the direction away from the cut workpiece 10, a negative pressure area is formed between the slope surface 261 and the cut workpiece 10, and the jacking force is less than the atmospheric pressure. Since the sleeve 200 is movably connected with the connecting assembly 300 in the axial direction of the sleeve 200, under the combined action of the jacking force and the atmospheric pressure, the sleeve 200 can maintain a small distance from the cut workpiece 10 and float above the cut workpiece 10, achieving the effect of concentrating the cutting gas between the first end 210 and the cut workpiece 10.
[0045] Further, as shown in Figures 1 to 5 The connecting assembly 300 is provided with an annular cavity 310, the annular cavity 310 is coaxial with the sleeve 200 and extends in the axial direction of the sleeve 200, the side of the annular cavity 310 facing the cut workpiece 10 is provided with an opening, the sleeve 200 is movably arranged in the opening and is in sliding fit with the annular cavity 310. Further, the sleeve 200 can slide in the annular cavity 310 in the axial direction thereof, and the inner wall of the annular cavity 310 can guide the sleeve 200 in the axial direction, ensuring that the sleeve 200 can move reciprocally in the axial direction, i.e. ensuring that the sleeve 200 can float up and down relative to the cut workpiece 10.
[0046] Further, the inner wall and / or the outer wall of the sleeve 200 is provided with a convex portion 220, the side wall of the annular cavity 310 is provided with a limiting portion 311, the side of the convex portion 220 facing the cut workpiece 10 can contact the side of the limiting portion 311 away from the cut workpiece 10. In this way, the sleeve 200 can be axially limited, preventing the sleeve 200 from falling out of the annular cavity 310, and improving the reliability of the connection between the sleeve 200 and the connecting assembly 300.
[0047] Further, the protrusion 220 is located at the end of the sleeve 200 away from the first end 210, and the inner wall of the annular cavity 310 away from the side of the cutting workpiece 10 (hereinafter referred to as the bottom of the annular cavity 310) can be in contact with the side of the protrusion 220 away from the cutting workpiece 10. For the sake of description, the position of the sleeve 200 relative to the connecting assembly 300 when the protrusion 220 is in contact with the limiting portion 311 is referred to as the first position, and the position of the sleeve 200 relative to the connecting assembly 300 when the protrusion 220 is in contact with the bottom of the annular cavity 310 is referred to as the second position. The structure design limits the movement range of the sleeve 200 in the axial direction of the sleeve 200, so that the sleeve 200 can only move between the first position and the second position, thereby improving the controllability of the movement range of the sleeve 200.
[0048] Optionally, the connecting assembly 300 comprises a first connecting ring 320 and a second connecting ring 330, the first connecting ring 320 is located in the second connecting ring 330, and the first connecting ring 320 is connected with the second connecting ring 330 through threads, and the second connecting ring 330 is provided with a wall thickness reduction area 331 at the end thereof facing the cutting workpiece 10, so that the annular cavity 310 is formed between the inner wall of the wall thickness reduction area 331 and the outer wall of the first connecting ring 320. In the embodiment, the limiting portion 311 is located on the outer wall of the first connecting ring 320 facing the cutting workpiece 10, and of course, in other embodiments, the limiting portion 311 can also be located on the inner wall of the wall thickness reduction area 331.
[0049] Optionally, the sleeve 200 is an insulating element, and the distance between the gas outlet end 110 and the first end 210 in the axial direction of the sleeve 200 is smaller than the distance between the side of the connecting assembly 300 facing the cutting workpiece 10 and the first end 210, thereby improving the stability of the capacitance value during the cutting operation. Specifically, during the cutting operation, the capacitance value of the part with the smallest distance from the cutting workpiece 10 is calibrated to zero, and then the follow-up height of the cutting is controlled based on the part. In the embodiment, since the sleeve 200 is an insulating element, and the distance between the gas outlet end 110 and the first end 210 in the axial direction of the sleeve 200 is smaller than the distance between the side of the connecting assembly 300 facing the cutting workpiece 10 and the first end 210, the capacitance value of the gas outlet end 110 of the nozzle 100 can be calibrated to zero, and the capacitance value of the gas outlet end 110 of the nozzle 100 can be calibrated to zero during the cutting operation. Therefore, during the cutting operation, the follow-up height of the cutting can be controlled based on the gas outlet end 110 of the nozzle 100, thereby improving the control accuracy of the follow-up height.
[0050] In this embodiment, the sleeve 200 is a non-metallic high-temperature-resistant insulating element such as a ceramic element or a polyether ether ketone (peek) element, which can reduce the probability of damage to the sleeve 200 caused by high temperature while ensuring the insulation performance of the sleeve 200.
[0051] In the natural state, the sleeve 200 is located at the first position under the action of gravity, that is, the protruding part 220 of the sleeve 200 is placed on the limiting part 311 of the connecting assembly 300, the laser cutting nozzle structure for cutting the groove is moved above the workpiece 10 to be cut, the bottom of the sleeve 200 contacts the workpiece 10 to be cut, and the nozzle 100 is continuously moved downward, so that the nozzle 100 and the connecting assembly 300 are both moved relative to the workpiece 10 to be cut in the direction towards the workpiece 10 to be cut. At this time, the bottom of the sleeve 200 is located on the workpiece 10 to be cut, and the sleeve 200 moves relative to the connecting assembly 300 in the annular cavity 310 until the distance between the gas outlet end 110 of the nozzle 100 and the workpiece 10 to be cut reaches a suitable size, and the movement of the nozzle 100 is stopped. At this time, the sleeve 200 is located approximately between the first position and the second position, that is, the protruding part 220 is located between the limiting part 311 and the bottom of the annular cavity 310.
[0052] The nozzle 100 is tilted so that the gas outlet end 110 of the nozzle 100 and the workpiece 10 to be cut form an angle, for example Figure 3 The nozzle 100 is tilted so that the gas outlet end 110 of the nozzle 100 and the workpiece 10 to be cut form an angle, for example
