What should be noticed at the scene when operating an automatic roll welder? Today, we will discuss with you:
Combustibles inside the welding area of the roll welder need to be cleared or covered with non-combustibles. Do not place flammable gases in the welding area.
Please set up fire fighting equipment in the welding area to prevent accidents such as fire or explosion caused by welding splashes.
When the roll welder is not in use, please turn off the power, compressed air and cooling water of all devices, confirm the surrounding situation of the welder and then turn on the power and compressed air of the welder.
Do not put your hands, wrists or other body parts between the electrodes of the roll welder, which may be clamped by the electrodes, causing fractures or other injuries. When the noise is loud, please use soundproof protective equipment.
Please use protective equipment such as gloves, long-sleeved work clothes and leather aprons, and use eye protection with sufficient shading.
Pay attention to arc flashes and splashes, which may burn your eyes and skin. Noise can cause hearing abnormalities.
If you come into contact with charged parts outside the secondary conductor of the roll welder, it may cause fatal electrode or burn injuries.
Roll welding is generally used to connect workpieces of similar or different materials along continuous seams. Here are some maintenance methods for roll welders.
When the cutter drops during operation, the induction switch of the cutting plate of the roll welder can be slowly adjusted until the cutter returns to its normal position.
The straightening method of the roll welder generally uses a waveform straightening method, but the wave cannot be too large, to avoid the increase of traction force resistance, which may cause the traction wheel to not move and the traction wheel to break the steel bar.
If there is a wire running situation, check whether the lower equipment is too tight for the coil spring or too loose for the sliding spring, otherwise it may be caused by the steel bar being not in place under the wire rod of the sliding block.
After the steel bar comes out of the pipe, if it lifts up, adjust the upper set of wheels to press down appropriately. If the steel bar goes under the pipe, adjust the lower set of wheels to rotate appropriately, so that the head of the steel bar is in a horizontal state.
When bending double bars on the roll welder, the bending axis will fall off, causing the outer wheels of one set of wheels to straighten and press inward, making the two steel bars tightly connected together. When the large stirrup is bent, the bending speed should be slowed down accordingly.
When there is a bending wire situation, adjust the angle of the lower straightening block, which should be in line with the straightener and the pressure roller groove.
Adjust the bending pin of the roll welder, adjust the lifting frame roller, make the highest point of the bending pin and the lower edge of the wire rope hole horizontal or 1-2 mm below the lower edge of the wire rope hole.
If there is a wire breakage during bending, check if the knife is normal, whether the spring sheet on the wire roll is too loose, or whether it is caused by poor material quality.
