Description

Technical Field

[0001] The invention relates to the technical field of roll welding machines, in particular to a double-sided synchronous roll welding mechanism for composite materials. Background Art

[0002] Roll welding machine is a machine used for roll welding, also known as girth welding, which uses a pair of roller electrodes to replace the cylindrical electrodes of spot welding. The workpieces to be welded move between the rollers to produce a sealed weld with overlapping molten cores to weld the workpieces together. Generally, an adjustable stroke cylinder is used for pressurization to avoid collision damage between the upper and lower electrodes. It adopts a three-phase stepless speed regulation electrode drive, and the welding speed is easy and stable to adjust. The ingenious and reasonable internal structure reduces the weakening of welding performance caused by heat. The silver bearing rotates and has excellent electrical conductivity and contact. Minimize the loss of electric energy conversion; There are still some problems in the use of the existing seam welding mechanism of the seam welding machine, specifically: 1. When the existing roll welding mechanism is in use, it is not convenient to perform uniform synchronous welding on the two sides of the composite material. This is because when the existing roll welding mechanism is in use, two cylinders are used to drive two roller electrodes to move respectively to achieve the extrusion of the composite material and to perform welding at the same time. However, in this process, the distance between the roller electrodes and the composite material is not the same. This makes it impossible to ensure that the two roller electrodes exert the same pressure on the composite material when the composite material is stretched straight and the two roller electrodes move to contact the composite material, and thus it is impossible to ensure that the two sides of the composite material are welded synchronously, thereby affecting the welding quality. 2. When using the existing roll welding mechanism, it is not convenient to automatically make the axial surface of the composite material welding part and the symmetry surface of the two roller electrodes coplanar. In order to make the two sides of the composite material welding part be welded synchronously, the composite material welding part needs to be adjusted to the symmetry surface of the two roller electrodes, which requires adjusting the height of the roller supporting the composite material, which is not convenient for the staff to operate; Therefore, a double-sided synchronous composite material roll welding mechanism is needed to solve the above problems.

The first follower rod 7 has an F-shaped structure, and the outer diameter of the upper end of the first follower rod 7 matches the inner diameter of the strip-shaped through groove 9, which can facilitate the movement of a single first follower rod 7 to drive the first movable plates 12 of the same group to move away from or closer to each other.

[0020] Embodiment 2: In order to solve the problem that the previous roll welding mechanism cannot make the two electrodes of roll welding move close to each other at the same speed, and thus cannot perform stable synchronous welding on both sides of the composite material, specifically, the synchronization component includes a first servo motor 4, a motor frame 5, a shaft rod 14, a worm sleeve 15, a second movable plate 17, a second plate sleeve 18, a second oblique through groove 19, a second follower rod 20, a transmission shaft 26 and a worm gear 27. The first servo motor 4 is installed on the upper surface of the support frame 2 through the motor frame 5, and the shaft end of the first servo motor 4 is coaxially fixedly connected to the upper end of the shaft rod 14, and the upper end of the shaft rod 14 is movable and penetrates to the top of the support frame 2. The outer movable sleeve of the shaft rod 14 is provided with a worm sleeve 15, and the worm sleeve 15 is provided with 2, 2 worms The sleeves 15 are respectively meshed and connected to the two worm gears 27, and the worm gears 27 are keyed to the corresponding transmission shafts 26. The front and rear sides of the support frame 2 are provided with strip openings, and the two strip openings are fixedly connected with the second plate sleeves 18.

The first servo motor 4 runs, driving the shaft 14 to rotate, and then the worm sleeve 15 on it drives the worm wheel 27 to rotate. The worm wheel 27 drives the roller electrode 23 to rotate synchronously through the transmission shaft 26. The roller electrode 23 is connected to the circuit, so when it is used as an electrode of the circuit and contacts the composite material to be welded, it will melt the surface of the composite material due to resistance heat, thereby achieving the welding effect. In addition, in the process of the limit rod 16 moving with the circular frame 8, it will also drive the second follower rod 20 to move in the second oblique slot 19, so as to achieve the purpose of the two second movable plates 17 of the same group approaching or moving away from each other. Then, the purpose of adjusting the distance between the two roller electrodes 23 is achieved, and the two roller electrodes 23 are used to stably extrude the double sides of the composite material, which is conducive to the synchronous welding of the double sides of the composite material. At the same time, the pressure sensor can sense the extrusion force of the composite material between the upper and lower guide rollers 6 in real time, ensuring that when the upper and lower guide rollers 6 are close to each other, the axial surface of the composite material to be welded can be coplanar with the symmetry surface between the two roller electrodes 23, so as to ensure the synchronization and uniformity of the welding of the double sides of the composite material. The middle part of the shaft rod 14 and the through hole for the shaft rod 14 to pass through on the worm sleeve 15 are mutually matched prismatic shapes, and the lateral distance of the second oblique groove 19 is less than the minimum distance between the end of the second oblique groove 19 away from the worm sleeve 15 and the worm sleeve 15.The connection mode between the worm sleeve 15 and the shaft 14 allows the worm sleeve 15 to slide on the shaft 14 without affecting the purpose of the shaft 14 driving the worm sleeve 15 to rotate stably. In addition, by setting the distance, the worm sleeve 15 can be prevented from hindering the movement of the second follower rod 20. The structure formed by the first plate sleeve 11, the first movable plate 12 and the first oblique groove 13 of the same group is the same as the structure formed by the second plate sleeve 18, the second movable plate 17 and the second oblique groove 19, and the height of the two groups of structures is the same, which can ensure that after the upper and lower guide rollers 6 clamp the composite material, the two roller electrodes 23 also clamp the composite material synchronously, thereby ensuring that the axial surface of the position where the composite material is to be welded is coplanar with the symmetry surface of the two roller electrodes 23, which is beneficial to avoid deformation of the composite material during the cooling stage after welding, thereby affecting the welding quality. The two first oblique grooves 13 of the same group form an "eight" shaped structure.

[0021] It should also be noted that how to energize the two roller electrodes 23 is a prior art, and although it is not described in detail in the present technical solution, it does not affect the implementation of the present technical solution.

[0022] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
