Description

Technical Field

[0001] This utility model relates to the technical field of flash butt welding machines for saw blades, specifically a fully automatic flash butt welding machine for saw blades. Background Technology

[0002] Currently, welding machines used for welding ring saw blades on the market require clamping the two saw blades together before welding. However, the clamping mechanisms used in these machines are all open-type, which have poor reliability in clamping the saw blades. As a result, the saw blades are prone to displacement during welding, leading to poor bonding at the weld joint. Furthermore, current welding machines cannot effectively press the two saw blades together tightly, resulting in poor bonding at the weld joint after welding.

[0003] However, existing saw blade flash butt welding machines have problems with interface displacement during the welding process, and the welding pre-pressure is not appropriate. The interface is statically welded, resulting in poor saw blade butt welding effect. Utility Model Content

The pre-pressing component includes a pusher 28, a movable plate 29, and a set of connecting side plates 30. The two ends of the connecting side plates 30 are respectively mounted on the movable plate 29 and the pusher block 24.

[0031] Compared with traditional technology: two saw blades with pre-cut straight ends are placed between the first electrode plate 9 and the first pressure plate 8, and between the second electrode plate 12 and the second pressure plate 7. The first driving component 3 drives the first pressure plate 8 to descend and press the saw blade on one side, and the second driving component 4 drives the second pressure plate 7 to descend and press the saw blade on the other side, thus avoiding the problem of the saw blade displacement at the interface during the welding process.

The welding power supply is turned on, and the weld joint heats up. The infrared temperature measuring component 15 includes an infrared temperature measuring probe and a probe mounting base. The infrared temperature measuring probe is used to measure the temperature of the weld joint. When the infrared temperature measuring component 15 senses that the temperature has reached the preset value, the upsetting cylinder drives the top block 25 to move, causing the push block 24 to push the second sliding component to move and causing the pre-pressure to suddenly increase. At the same time, the servo motor rotates at a set speed, driving the drive cam 22 to rotate, so that the end of the movable side saw blade moves at a set temperature and at a set speed and distance to achieve the best welding effect. Then, the welding power supply is turned off, and the cooling air is blown according to the set cooling to control the cooling rate and achieve the best quenching effect. When the temperature drops to the set temperature, the tempering power supply is turned on to temper the weld joint. As needed, parameters such as the number of tempering times, temperature, and holding time can be set to complete the welding.
