Rail welder, rail welder prices

Rail welder, welding machine price rail rail welder main principles and methods ① welding preparation: Remove 200m or so (depending on the production schedule) of track fasteners, welding rail - head grinding, sawing after the rail - head end surface smooth surface requirements verticality to meet the requirements, no rust before welding, grinding electrode holding parts of the two-track rail head back approximately 0.5m, and keep them clean. Zy01 ② moving vehicle and parked it in the proper position, lifting rear of the vehicle so that the rear wheels leave the track surface about 10cm (easy fitting adjustment), welder placed rail surface, manually adjust the front rail position, and make the next car rail ride , rail end gap to meet the requirements (generally 1 ~ 2mm), the electrode holding back on track. (After the test to determine the voltage, current, upset force and time parameters have been set in advance within a computer) power to begin early welding, the welding, weld end, upset, shearing and so the entire welding process, Since the beginning of welding to upset the process duration of about 2 to 3 minutes, burnt upset distance (ie, shorten the length of the rail) 35 ~ 45mm. ③ after welding work: joint grinding process, and timely to joints normalizing treatment to improve the welding strength, reinstall and tighten the fastener. Rail welding machine main technical parameters: Rated voltage: 380 + 10% V diesel generator power: 600KW diesel generator output voltage: 400V hydraulic system working pressure: 100kg / cm2 forging force: 1000KN clamping force: 2500KN Maximum soldering area: 12000mm2 Productivity: 12 horn / h (continuous flash when) Productivity: 18 horn / h (pulse flash) Weight: 3000kg (horn section) Dimensions: (L × W × h): 1590 × 965 × 1300mm ( horn section) push-filled way: push-filled packing because production batch, the specific model is different from the above picture for reference only, please contact our sales staff will be specifically verified.
