The type of Spiral welded pipe api and the transformation of slagging device
Manufacturing process of the molding process is characterized by the same width of the strip can be used to shape a variety of diameter steel pipe, can also be used with a variety of width of the same diameter of the steel pipe. This process is characterized by changing the mounting angle (forming angle) of the forming device. The change of the forming angle first needs to establish the center point of the adjustment of the relevant elements. The location of these centers is one of the main contents of the spiral welded pipe forming process design. 1 The type of swing center spiral welded pipe forming process can be roughly divided into two types of pendulum and pendulum. For the pendulum molding process, there are four control centers in the forming process, namely the rear axle swing center, the rear axle swing fine adjustment center, the forming tool swing center and the forming suture center; for the front pendulum molding process, the molding process control center There are three, namely the front axle swing center, rear axle swing fine center and forming suture center. Whether these central locations are set is reasonable and can be an important condition for stable control molding. 1.1 rear axle swing center in the pendulum forming process, the molding adjustment must be adjusted when the rear axle according to the molding angle α, as the molding machine to adjust the same angle α. In general, in the post-pendulum forming process, the swing center of the rear axle is concentrically aligned with the swing center of the forming device.
In the spiral pipe production process, pouring welding residue is an indispensable process of production. So that the spiral pipe equipment slant tilted a certain angle so that the pipe slag along the pipe body out of the slope, this "down" method commonly known as pour dregs, such a device known as the slag device. In order to meet the needs of the second-generation steel pipe production, we put the original 820 unit slag turning bridge device was modified from the original bridge tilted 40 ° tilted into a smaller angle, the welding slag from the tube down Out, and to achieve automatic control operation, so that the slag device is more reliable and safe. The working principle of the slagging device. The slagging device must first be taken over, that is, the tube through the floor roller into the slag platform. Spiral pipe equipment in the static under the angle of rest of 40 °, according to this angle, the bridge will be one end from the ground is very high, the other end down to the ground below 4m deep, neither safe nor unstable. In order to reduce the elevation angle of the bridge, but also to the pipe within the welding slag "disturbance", into a dynamic, increase the sliding slag driving power, in the slag bridge added two rollers as a disturbance device. The rotation of the roller drives the rotation of the tube, and the slag in the pipe slides out along the pipe wall.
