When pressing the two strips, the force on each part is relatively uniform, and the effect is very good for thin strips, but when the thickness of the strip is greater than 6mm, or the temperature of the raw material is slightly lower (under the premise of ensuring the plasticization of the material , the lower the temperature, the less damage to the material, but the hardness of the material in the molten state will increase), and the pressing force needs to be increased to fit the two strips tightly to the winding mold. At this time, the aluminum bracket Due to excessive force, the friction between the PTEF wafer and the aluminum bracket becomes larger, and it will not be able to synchronize with the winding speed or even stop rotating. This will squeeze the material tape so that it cannot rotate with the winding mold, so that the material belt pull off

The invention relates to the technical field of winding pipe manufacturing, and particularly relates to a guiding and compressing device for a heat-state winding pipe. The guiding and compressing device comprises a fixed seat, a transverse adjusting mechanism, an angle adjusting mechanism, a longitudinal adjusting mechanism, a compressing mechanism and a guiding mechanism. The transverse adjusting mechanism is located above or below the fixed seat. The angle adjusting mechanism is connected with the left end of the transverse adjusting mechanism. The lower portion of the longitudinal adjusting mechanism is connected with the upper portion of the angle adjusting mechanism. The compressing mechanism and the guiding mechanism are arranged on the longitudinal adjusting mechanism. According to the device, material belts needing to be bonded together in the heat-state winding structure pipe production process can be bonded well, and clearances existing between the adjacent material belts wound on molds afterwards in a bonding area and the molds can be eliminated.
Description
technical field [0001] The invention relates to the technical field of winding pipe preparation, in particular to a guiding and pressing device for hot winding pipes. Background technique [0002] During the production of hot-wound structural pipes, it is necessary to bond together the molten state tape previously wound onto the mould, and the molten state tape to be wound onto the mould. When the two tapes are lapped, there is a joint area. There is a gap between the tape that is adjacent to this joint area and is wound on the mold and the mold, and the bonding seam in the joint area is not firmly bonded. In order to make the two material strips adhere firmly and stick together tightly with the winding mold to form a smooth inner surface of the tube, a pressing device is required to compress the junction of the two material strips and tightly fit on the winding mold. During the pressing process, the force required for the material tape wound on the mold is different due to...
