Description

Technical Field

[0001] The present invention belongs to the technical field of laser welding, and in particular relates to a thick plate laser-arc complementary composite welding device and method based on energy siphon effect. Background Art

[0002] Arc welding is one of the most commonly used welding methods. This method has low equipment cost and strong process adaptability, but due to its relatively low energy density and large heat input, it is easy to cause a large heat-affected zone and welding deformation in the workpiece. Especially when welding medium and thick plates, multi-layer and multi-pass welding is often required, which not only has low work efficiency, but also easily produces defects such as interlayer slag inclusion and unfused. Laser welding has the advantages of high energy density, small heat-affected zone and small deformation. However, this method also has obvious shortcomings: on the one hand, the investment cost of laser equipment is high; on the other hand, when welding medium and thick plates, due to the gradual attenuation of laser energy along the depth direction, problems such as insufficient root penetration and poor fusion often occur, and the stability of the keyhole is also difficult to guarantee. In order to overcome the limitations of single heat source welding, laser-arc hybrid welding technology came into being. This technology adopts the synergistic effect of laser and arc: the arc heat source can preheat the workpiece and improve the absorption efficiency of laser energy; the deep melting characteristics of the laser ensure good welding penetration. In laser arc hybrid welding, the so-called "energy siphon effect" is not a common term, but it can be understood as the energy transfer and utilization phenomenon when the laser and arc interact. Among them, the wire feeding structure used in the hybrid welding equipment is particularly important, and the position of the wire feeding determines the quality of the welded product.

[0003] However, there are some problems with the prior art: when the laser arc hybrid welding equipment is performing welding work, the wire feeding mechanism used in conjunction with the equipment can only place the welding wire in a single direction. When welding plates with a wider gap width, the wire feeding mechanism is required to cooperate with the welding gun to perform swing welding, so that the welding wire swings along the width direction of the gap during the welding process, thereby filling the gap more evenly. This causes welding position deviation during arc welding and laser welding, resulting in a decrease in welding quality. There are certain limitations. Therefore, we propose a thick plate laser-arc complementary hybrid welding device and method based on the energy siphon effect. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a thick plate laser-arc complementary hybrid welding device and method based on the energy siphon effect.

[0028] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 13 As shown, a thick plate laser-arc complementary hybrid welding device based on energy siphon effect provided by an embodiment of the present invention includes a hybrid welding mechanism 2 and a wire feeding wheel 22, the hybrid welding mechanism 2 is composed of an arc welding machine 201, a high-power laser 202, a laser welding head 203 and an arc welding gun 204, the high-power laser 202 and the laser welding head 203 are used in conjunction with each other, the arc welding machine 201 and the arc welding gun 204 are used in conjunction with each other, the outer fixed sleeve of the laser welding head 203 is provided with a mounting sleeve 1, the arc welding gun 204 is arranged on one side of the laser welding head 203 through the mounting sleeve 1, the outer end of the mounting sleeve 1 away from the arc welding gun 204 is movably connected with a wire feeding housing 4, the wire feeding wheel 22 is arranged inside the wire feeding housing 4, and also includes: A repeated driving component 10 is arranged at the bottom of the wire feeding housing 4, and a wire feeding tube 6 is movably connected to the bottom of the wire feeding housing 4. The wire feeding tube 6 is transmission-connected to the repeated driving component 10, so that the wire feeding tube 6 is repeatedly horizontally moved at the bottom of the wire feeding housing 4 by the repeated driving component 10; The outside of the wire feeding wheel 22 is wound with a welding wire 5; like Figures 1 to 13 As shown, due to the design that the wire feeding tube 6 is repeatedly driven by the assembly 10 to move horizontally at the bottom of the wire feeding housing 4, the welding wire 5 can be preliminarily adjusted in position.

[0030] A transmission assembly 12, the transmission assembly 12 is transmission-connected to the repetitive driving assembly 10, and the transmission assembly 12 is movably connected to the wire feeding housing 4, the transmission assembly 12 is used to support the wire feeding housing 4, a positioning seat 16 is correspondingly provided at the bottom of the wire feeding housing 4, and the positioning seat 16 is fixedly connected to the transmission assembly 12; a bending assembly 9, the bending assembly 9 is arranged on one side of the positioning seat 16, the bending assembly 9 is composed of two groups of adjusting rods 902 and a bending mechanism, the bending mechanism is transmission-connected to the wire feeding tube 6, and the two groups of adjusting rods 902 are transmission-connected to the bending mechanism, so that the two groups of adjusting rods 902 are close to or away from each other through the bending mechanism; like Figures 1 to 13As shown, since the two groups of adjusting rods 902 are designed to move closer to or farther from each other through the bending mechanism, the two groups of adjusting rods 902 are close to each other, and the welding wire 5 can be bent, thereby achieving the bending of the welding wire 5 and evenly laying it in the gap of the weldment, thereby effectively improving the welding quality.

[0031] The pressing assembly 11 is arranged on the other side of the positioning seat 16 , and the pressing assembly 11 is transmission-connected with the transmission assembly 12 , so that the pressing assembly 11 is arranged to move up and down on the other side of the positioning seat 16 through the transmission assembly 12 .

[0032] like Figures 1 to 13 As shown, due to the design that the pressing component 11 is arranged on the other side of the positioning seat 16, the welding wire 5 bent by the two sets of adjusting rods 902 will be pressed down and shaped by the pressing component 11, thereby preventing the welding wire 5 from rebounding, resulting in a smaller bending degree and reduced welding quality.

[0033] Due to the design that both the pressing component 11 and the repeated driving component 10 are connected to the transmission component 12, after the welding wire 5 is bent, the pressing component 11 will also be pressed down synchronously. Therefore, in conjunction with the movement of the arc laser hybrid welding mechanism 2, it can be ensured that the welding wire 5 is evenly and stably laid in the gap between the weldments, thereby effectively improving the welding quality.

[0034] Furthermore, the repetitive driving assembly 10 includes a connecting seat 101 and a movable sleeve 102, the connecting seat 101 is rotatably installed at the bottom of the wire feeding housing 4, the lower end of one side of the wire feeding housing 4 is threadedly connected with a fastening bolt 8, the connecting seat 101 is fixed to the wire feeding housing 4 by the fastening bolt 8, the connecting seat 101 is hollow, the wire feeding tube 6 is located inside the connecting seat 101, and positioning shells 104 are fixedly installed at both ends of the bottom of the connecting seat 101, sliding grooves are provided on opposite sides of the two groups of positioning shells 104, and sliding seats 103 are slidably connected inside the two groups of sliding grooves, the movable sleeve 102 is fixedly installed between the two groups of sliding seats 103, and the movable sleeve 102 is fixedly sleeved on the outside of the wire feeding tube 6; like Figures 1 to 13 As shown, due to the design that the connecting seat 101 is fixed to the wire feeding tube 6 by the fastening bolts 8, the angle of the connecting seat 101 can be rotated and fixed. Therefore, the horizontal repetitive motion trajectory of the wire feeding tube 6 can be changed according to the connecting seat 101, so that corresponding adjustments can be made according to the requirements of the weldment gap.

[0035] Further, the repetitive driving assembly 10 further includes two groups of rotating disks 106, the outer sides of the two groups of rotating disks 106 are both rotatably sleeved with positioning sleeves 13, and the positioning sleeves 13 are fixedly connected to the positioning shell 104, and a reversing gear set 107 is arranged between the two groups of rotating disks 106, so that the two groups of rotating disks 106 are arranged to rotate in opposite directions through the reversing gear set 107, and one end of the two groups of rotating disks 106 on the side away from each other is rotatably connected to a connecting rod 105, and one end of the two groups of connecting rods 105 is rotatably connected to the two groups of sliding seats 103 respectively, and one end of the connecting rod 105 passes through the outer side of the positioning shell 104 to the inside of the sliding groove; like Figures 1 to 13 As shown, through the mutual cooperation of two groups of rotating disks 106 and two groups of connecting rods 105, the mutual cooperation of the rotating disks 106, the connecting rods 105 and the sliding seat 103, rotational reciprocating linear motion can be realized, thereby completing the horizontal reciprocating motion of the wire feeding tube 6.

[0036] It should be noted that if Figure 7 As shown, the reversing gear set 107 mentioned above can be used in combination of three groups of identical gears on the top and two groups of identical gears on the bottom. It is a conventional technical means to use multiple gears to realize the synchronous and opposite rotation of the two groups of rotating disks 106. Those skilled in the art should know how to install five groups of gears to realize the synchronous and opposite rotation of the two groups of rotating disks 106. Therefore, the present invention will not be elaborated here.

[0037] It is worth mentioning that by designing two sets of rotating disks 106 and two sets of connecting rods 105 to cooperate with each other, the movable sleeve 102 is controlled to drive the wire feeding tube 6 to move repeatedly, and the two sets of sliding seats 103 slide symmetrically and synchronously, so that the wire feeding tube 6 can move more stably.

[0038] Furthermore, a slide groove is provided on the side away from each other of the two sets of rotating disks 106, and an adjusting slide plate 15 is slidably connected inside the slide groove, and a threaded hole is provided at one end of one side of the adjusting slide plate 15, and a fixing bolt 14 is threadedly connected inside the threaded hole, so that the adjusting slide plate 15 is fixed to the rotating disk 106 by the fixing bolt 14, and the other end of the connecting rod 105 is rotatably installed on the other end of one side of the adjusting slide plate 15; like Figures 1 to 13 As shown, the position of the connecting rod 105 on the rotating disk 106 can be adjusted by adjusting the slide plate 15, so that the connecting rod 105 can be adjusted to cooperate with the rotating disk 106 to control the repeated movement area of ​​the wire feeding tube 6 according to the width of the weld gap. Therefore, the wire feeding mechanism of the present invention is suitable for the weld gap in multiple scenarios.

The upper end of the second synchronization mechanism 1203 is connected to the bevel gear transmission mechanism 1202, which is arranged inside the transmission groove, and the end of the bevel gear transmission mechanism 1202 is connected to the transmission gear 1201. A docking groove is provided at the upper end of one side of the fixed shell 1204, and the inside of the docking groove is communicated with the inside of the transmission groove. The transmission gear 1201 is rotatably installed inside the docking groove, and a plurality of groups of tooth grooves are provided on the outer side of one group of rotating disks 106, and one group of rotating disks 106 is meshed and connected with the transmission gear 1201 through the tooth grooves; like Figures 1 to 13 As shown, through the design of the moving wheel 1205, the bevel gear transmission mechanism 1202, the second synchronization mechanism 1203 and the transmission gear 1201, the moving wheel 1205 contacts the upper surface of the weldment. When the arc laser hybrid welding mechanism 2 is in the process of moving welding, the moving wheel 1205 can use the bevel gear transmission mechanism 1202, the second synchronization mechanism 1203 and the transmission gear 1201 to make the two sets of rotating disks 106 rotate at the same time, control the horizontal repeated movement of the wire feeding tube 6, and perform the work of bending the welding wire 5. Therefore, there is no need to design an additional electric drive device to achieve the bending of the welding wire 5, thereby reducing the cost of bending the welding wire 5 on a certain basis and improving the welding quality.

[0040] For example, Figure 8 As shown, the speed gear set 1206 mentioned above can be used with a speed gear structure, and the speed gear set 1206 has become a mature speed change technology. Those skilled in the art should know how to install and use the speed gear set 1206 to realize the moving wheel 1205 driving the second synchronization mechanism 1203. Therefore, the present invention will not be elaborated here.

[0041] It should be noted that if Figure 8 As shown, Figure 8 The structure located on the left side of the moving wheel 1205 is the adjustment structure of the speed change gear set 1206. Those skilled in the art should know how to install and use it. Therefore, the present invention will not be described in detail here.

[0042] Through the design of the speed change gear set 1206, the frequency of the moving wheel 1205 driving the repeated drive assembly 10 can be adjusted according to the depth of the weld gap, thereby ensuring the uniformity of the bending of the welding wire 5 in different weld gaps.
