Description
Technical Field
The invention relates to the technical field of pipe processing, in particular to a U-shaped pipe welding auxiliary device and a welding auxiliary method.
Background
The welding principle of the U-shaped pipe is that a heated soldering iron is mainly used for heating and melting solid soldering tin wires, and the main effect of a soldering flux is utilized to ensure that the melted soldering tin wires can smoothly flow into the middle of the welded metal, and after the soldering tin wires are completely cooled, a reliable and firm welding point can be formed.
When U-shaped pipe and some welded component are welded, for example, when U-shaped pipe and flange are welded, need 306 rotate the U-shaped pipe, need two people to rotate the U-shaped pipe generally, not only waste time and energy, can't guarantee moreover that the mouth of pipe of U-shaped pipe after rotating and flange welded position is in horizontal position all the time, once the U-shaped pipe slope, the welding position of U-shaped pipe and flange just appears the gap very easily, can't guarantee product quality.
The chinese patent publication No. CN 104107998B discloses a support device for welding a U-shaped pipe orifice flange, comprising: the round support plate comprises a first half support plate and a second half support plate, and semicircular grooves are formed in the first half support plate and the second half support plate. The working principle of the U-shaped pipe comprises the steps of firstly separating the first half supporting plate from the second half supporting plate, putting the U-shaped pipe into the semicircular groove, then enabling the first half supporting plate and the second half supporting plate to be combined together to form a complete circular supporting plate, then fixing the first half supporting plate and the second half supporting plate through locking bolts, and finally rotating the circular supporting plate under the supporting of the roller wheels under the circular supporting plate to realize the rotation of the pipe orifice of the U-shaped pipe at the horizontal position all the time. Although the problem that gaps are easy to appear at the welding positions of the U-shaped pipe and the flange is solved in the publication, the requirement on staff is very high when the circular support plate is manually rotated, the force control force of the staff is not very accurate, particularly under the condition that the working time is too long and fatigue is caused, the force applied by the staff to the circular support plate cannot be controlled to cause the rotation speed of the circular support plate to be out of control, meanwhile, the rotation speed of the circular support plate is out of control possibly caused by vibration force caused by welding equipment or other peripheral equipment, and as a result, the part of the U-shaped pipe cannot reach the welding temperature due to the fact that the rotation speed of the circular support plate is too fast, and the unwelded defects such as cold welding, unwelded welding and the like can be caused; the welding stability is affected by the region with too slow rotation, and the heating temperature of the groove surface of the U-shaped pipe is greatly higher than the temperature required by welding, so that the defects of serious splashing, pinholes, slag inclusion and the like are caused, and the defects are called overburning defects, which affect the product quality. Meanwhile, the fact that the rotation speeds of the round supporting plates are different can also cause that some parts of welding areas of the U-shaped pipe and the flange are welded in the welding process of the U-shaped pipe and the flange, and other parts are not welded, so that the production efficiency of products is affected.
