Description

Technical Field

[0001] The utility model relates to the technical field of resistance welding machines, in particular to a cylinder type resistance welding machine. Background Art

[0002] Resistance welding machine refers to a welding equipment that uses the principle of resistance heating for welding. Resistance welding machines can be divided into different types according to different uses and requirements. From the classification of welding methods, there are spot welding machines, seam welding machines, projection welding machines and butt welding machines; from the classification of electrode pressure forms, there are lever type, electric cam type, pneumatic type, hydraulic type and pneumatic and hydraulic combined type; from the classification of welding current types of resistance welding machines, there are single-phase industrial frequency welding machines, secondary rectifier welding machines, three-phase low-frequency welding machines, capacitor energy storage welding machines and inverter power supply welding machines. Resistance welding machines are mainly composed of main circuit parts, pressure transmission parts and control parts.

[0003] However, the existing resistance welding machines have poor stability and cannot allow the pressure head assembly to bear a larger lateral force. During the welding process, the upper and lower pressure heads are prone to deviation due to the centering problem, which seriously affects the welding accuracy and the use effect is not ideal.

[0021] Specifically, the guide mechanism includes a slider 6 and a slide rail 7 slidably connected to the slider 6. No less than two sliders 6 are arranged on both sides of the output end of the cylinder body 2, and no less than two slide rails 7 are arranged on both sides of the inner wall of the welding machine base 1. The guide mechanism can allow the upper die head 32 to bear a larger lateral force to prevent the upper die head 32 and the lower die head 42 from shifting due to the centering problem during the welding process, and the welding process is more stable.

[0022] Specifically, an insulating plate 8 is provided between the output end of the cylinder body 2 and the upper mold 3, and between the welding machine base 1 and the lower mold 4. The insulating plate 8 is made of Teflon material. Teflon has high purity and strong chemical stability. It will not react chemically due to the inability to use media or other substances. It can withstand high temperature environments and can be used for a long time in high temperature environments above 200°C. It is widely used in equipment manufacturing under high temperature conditions and high temperature lubricating materials. Teflon has excellent corrosion resistance and can withstand the erosion of various chemical media. It is not easily corroded by acids, alkalis, and salts. Therefore, Teflon is widely used in chemical production, pharmaceutical and other industries. It can be used to make various corrosion-resistant pipes, valves, pumps and other equipment. Teflon also has excellent lubrication properties and can reduce the friction coefficient to a very low level, thereby reducing machine wear and reducing energy consumption. In addition, other characteristics of Teflon enable it to be widely used in the production of various sealing materials and bearings.

[0023] Specifically, the upper mold 3 includes an upper water-cooling block 31 and an upper mold head 32 embedded in one side of the upper water-cooling block 31, and the lower mold 4 includes a lower water-cooling block 41 and a lower mold head 42 embedded in one side of the lower water-cooling block 41.

Figure 1 A meter is also provided on one side of the welding machine base 1, which is used in conjunction with the pressure sensor 5 to accurately monitor the pressure and displacement during use. An electrical proportional valve is provided on the side of the cylinder body to more quickly adjust the pressure generated by the cylinder body 2.

[0025] In summary, the cylinder type resistance welding machine adopts the insulating plate 8 of Teflon material to ensure the insulation performance between the upper die 3, the lower die 4 and the welding machine base 1. The setting of the guide mechanism can allow the upper die head 32 to bear a larger lateral force, thereby preventing the upper die head 32 and the lower die head 42 from shifting due to the centering problem during the welding process. The welding process is more stable. The upper die head 32 and the lower die head 42 are both cooled by water to further ensure the stability of the upper die head 32 and the lower die head 42.
