Graphite copper plates 15 are provided on three sides of the linear motion component 4. The graphite copper plates 15 allow two separate single-sided double-spot welders to slide in the slide groove of the supporting base through the linear motion component 4. The graphite copper plates 15 provided on the outside of the linear motion component 4 cooperate with the graphite copper plates 15 on the supporting base, thereby increasing the wear resistance and reducing the friction.

An insulating gasket 27 is provided on the top of the main electrode holder 7. The insulating gasket 27 is generally made of a high-temperature resistant, high-insulation ceramic material, which can effectively prevent electrical short circuits between the electrode 17 and other components. An insulating sleeve 28 is provided on the top of the insulating gasket 27. The top of the insulating sleeve 28 is provided at the output end of the welding power cylinder 22. The output end of the welding power cylinder 22 is provided There are insulating gaskets 27 and insulating sleeves 28, which are used together to completely insulate the welding power cylinder 22 from the main electrode holder 7. A transformer 6 is provided inside the single-sided double-spot welding machine 1. The bottom of the transformer 6 is fixedly connected to a secondary conductor 18. The outer wall of the secondary conductor 18 is set on the outer wall of the main electrode holder 7. One end of the soft connection 19 is connected to the secondary conductor 18, and the other end is connected to the main electrode holder 7. When the output end of the welding power cylinder 22 drives the electrode to press down, the soft connection 19 moves with it to ensure that the welding current output by the transformer 6 can pass through the secondary conductor 18 and the soft connection 19, and finally output to the welding electrode. The welding power cylinder 22 The outer wall is fixedly connected to the electrode anti-rotation guide assembly 5, and a guide shaft 24 is provided inside the electrode anti-rotation guide assembly 5. One end of the guide shaft 24 is fixedly connected to the guide rod support sleeve 25. The outer wall of the guide shaft 24 is fixedly connected to the guide rod mounting bracket 23. The guide rod mounting bracket 23 is generally made of aluminum alloy. Its outer wall is firmly connected to the outer wall of the main electrode seat 7 to ensure that the main electrode seat 7 does not rotate during the up and down movement. The outer wall of the guide rod mounting bracket 23 is fixedly connected to the outer wall of the main electrode seat 7. A linear bearing 29 is provided at the connection between the guide shaft 24 and the welding power cylinder 22. An inductor contact 20 is provided on the top of the guide shaft 24.A proximity sensor 16 is fixedly connected to the outer wall of the cylinder reinforcement bracket 9.

The bottom of the spring 10 is fixedly connected to the strapping pressure rod 8. A solenoid valve 13 is installed on the outer wall of the single-sided double-spot welder 1. A transformer 6 is installed on the outer wall of the single-sided double-spot welder 1. A linear guide 12 is installed at the bottom of the support base 30.

The output end of the thin cylinder 2 is connected to the outer wall of the single-sided double-spot welder 1.

[0032] Specifically, first, with the help of the cooperation of the linear motion component 4 and the support base 30, the two single-sided double-spot welding machines 1 are installed in place. During the welding operation, the thin steel strip used as the packing strip is first overlapped under the welding machine through the strip supply mechanism (the strip supply mechanism will extend a copper plate, and the packing strip is overlapped on the copper plate). Then the thin cylinder 2 plays a driving role, prompting the single-sided double-spot welding machine 1 to slide on the support base 30. When the single-sided double-spot welding machine 1 slides into place, the welding power cylinder 22 starts to ventilate. Driven by the welding power cylinder 22, the two electrodes 17 are tightly pressed on the same side of the thin steel strip. The steel strip and the graphite copper plate 15 are used as conductors to conduct the welding current, thereby firmly welding the packing steel strips together. At the same time, the proximity sensor 16 accurately determines the cylinder status through the sensor contact 20 at the tail of the guide shaft 24, and feeds back the information to the PLC control system, so that the welding process is carried out. The strapping pressure rod mounting plate 26 first contacts the steel strip, and relies on the elastic force of the spring 10 to flatten the steel strip. Then the electrode 17 contacts the steel strip for welding. The solenoid valve 13 equipped on the single-sided double-spot welding machine 1 can effectively control the movement of the welding cylinder. In addition, there is a water distributor on the single-sided double-spot welding machine 1. External cooling water flows through the water distributor to cool the two electrodes 17 and the transformer 6. The linear guide rail 12 installed at the bottom is connected to the bottom plate of the support base 30, and the bottom plate can be installed on the beam. The support base 30 can drive two independent single-sided double-spot welding machines 1 to move along the axial direction of the beam to achieve synchronous and efficient welding. Based on the principle of medium-frequency resistance welding, the fully automatic production of profile steel from whole bundles to welding and packaging is realized, which improves the welding strength and accuracy, greatly improves work efficiency, and frees workers from high-intensity packaging and welding work, while also reducing the probability of safety accidents.

[0033] Working principle: When welding the profile, the single-sided double-spot welder 1 is installed by cooperating with the linear motion component 4 and the support base 30, and then driven by the thin cylinder 2 to slide the single-sided double-spot welder 1 on the support base 30. When the single-sided double-spot welder 1 is welding, the graphite copper plate 15 is used to move the single-sided double-spot welder 1 conveniently and accurately. The two electrodes 17 are driven by the welding power cylinder 22 and pressed on the same side of the thin steel strip. The steel strip and the graphite copper plate 15 are used as conductors to conduct the welding current, and the packaged steel strips are welded together. At the same time, the cylinder status is determined by the proximity sensor 16 and the sensor contact 20 at the tail of the induction guide shaft 24. , and feedback is given to the PLC control system. During welding, the strapping pressure rod 8 first contacts the steel strip, and the steel strip is flattened by the elastic force of the spring 10. Then the electrode 17 contacts the steel strip for welding, and the single-sided double-spot welding machine 1 is provided with a solenoid valve 13, which controls the action of the welding cylinder. At the same time, the single-sided double-spot welding machine 1 is provided with a water distributor, and external cooling water flows through the water distributor to cool the two electrodes 17 and the transformer 6. At the same time, a linear guide rail 12 is installed at the bottom, and the linear guide rail 12 is connected to the bottom plate of the support base 30. The bottom plate can be installed on the beam. The support base 30 can drive two independent single-sided double-spot welding machines 1 to move along the axial direction of the beam for synchronous welding.
