6 m high above the light pole in the fox buried after welding machine, welding ends, namely fluently and can present a big error, the longer the light pole joint deviation, the greater the more than 10 m is more obvious, joint they distort 180 degrees, this is precisely the reason why
6 m high above the light pole in the fox buried after welding machine, welding ends, namely fluently and can present a big error, the longer the light pole joint deviation, the greater the was more obvious than 10 meters, joint they distort 180 degrees, what causes this? It also in many ways.
light pole plate after cutting of the longitudinal cutting machine, be on one side of the shear due to rub out of the cutter for extrusion, there is a high pressure accumulator to hide. Fox this force will be buried under the high quantity of heat of welding to released, that is not on one side of the shear will be released by the side of the shear force pulling in the past, eventually leading to weld distortion.
steel thicker, More than 4 mm) Rarely will not appear this kind of circumstance, even like a light, every day in 10 meters, but few of weld distortion would happen. Because the thicker steel plate itself will naturally straight, and buried the fox not easy to cause the temperature is too high, around the weld natural storage when shear force is not easy to be released also won't appear the phenomenon of distortion.
when light pole production technology before mentioned question on the weld bead is not straight, the factors of straight is comprehensive, such as not straight cutting plate, coil rod bending plate two head feed inequality, buried fox was not correct. 。 。
a, cutting board, longitudinal cutting board to cut twice, which is steel plate on both sides of positive and negative each cut a knife, the purpose is to bury a fox when welding steel plate on either side of the force can mutual confluence, pull side walk do not side can largely avoid weld rotation.
2, joint: roll bending machine lamp pole do not immediately after the fox, but with the joint machine extrusion joint straightening, and straightening the good weld with welding point, every one the best. 5 m check it, so that light pole and correct weld will be solder joint force, when the fox buried must not deformation.
in the cause of problem occurred mainly related to process, omitted some link is bound to be a bad influence on the result. In other words, to guarantee the effect of light pole ultimately without faults have to do a good job in every little link.
