Description
Technical Field
The utility model belongs to the technical field of mechanical equipment, especially, relate to a circular steel pipe 90 degrees welding pay-off.
Background
When two circular steel pipes need to be connected at 90 degrees, firstly, a 90-degree welding opening line needs to be paid off on the outer circumferential surface of one circular steel pipe, and then, the opening is carried out according to the paying off, and the paying off work is always relatively complex. In the traditional method for welding and paying off the circular steel pipe at 90 degrees, various methods such as a wire drawing method and a paper folding method are adopted by different welders for paying off, but the methods are difficult to accurately and efficiently pay off the opening line. The method has the advantages that the discharged opening line has deviation, so that the appearance of a welded junction is poor, the paying-off process is complex and time-consuming in most methods, the working efficiency is difficult to guarantee, the axes of two circular steel pipes welded by 90 degrees are on the same plane, and the projection of the vertical section of the circular steel pipe to be welded on the circular steel pipe to be opened is difficult to guarantee.
Disclosure of Invention

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the 90-degree welding and paying-off device for the circular steel pipe provided by the invention comprises a support 1, a magnet 2, a support rod 3, a bearing 4, an adjusting bolt 5, an adjusting arm 6 and a line drawing rod 7; the support 1 is made of angle steel and is buckled on the outer circumferential surface of the round steel pipe 8, and the folding line at the top is parallel to the axis of the round steel pipe 8; the magnets 2 are arranged at two side parts of the surface of the support 1; the central hole of the bearing 4 is fixed at the upper part of the supporting rod 3 which is vertically arranged; the lower end of the support rod 3 is fixed on the top of the support 1; the adjusting arms 6 are horizontally arranged, one ends of the two adjusting arms 6 are fixed together by using the adjusting bolts 5, the other end of one adjusting arm 6 is fixed on the outer circumferential surface of the bearing 4, the other end of the other adjusting arm 6 is connected with a sleeve, and the sleeve is sleeved outside the vertically arranged line drawing rod 7, so that the line drawing rod 7 can move up and down.
And cross lines 9 are arranged on the top surfaces of the support rod 3 and the line drawing rod 7.
The length of the sideline of the support 1 is smaller than the diameter of the opening 10 on the circular steel pipe 8, otherwise, the drawing is influenced. However, the length of the sideline should be selected as long as possible so as to ensure that the axis of the opening is in the same plane as the axis of the circular steel tube 8.
Will now the utility model provides a circular steel pipe 90 degrees welding pay-off's application method explains as follows:
1. firstly, determining the radius of the opening 10 by a worker, then loosening the adjusting bolt 5 by using a wrench, rotating the adjusting arm 6 around the adjusting bolt 5, measuring the center distance between the supporting rod 3 and the cross line 9 at the top end of the line drawing rod 7 by using a ruler, and screwing the adjusting bolt 5 by using the wrench when the distance is equal to the radius of the opening 10;
2. buckling the support 1 on the outer circumferential surface of the circular steel pipe 8, enabling one edge line of the support to pass through the central point of the opening 10, then taking the central point of the opening 10 as the vertex, measuring the radius distance of the opening 10 on the circular steel pipe 8 by using a ruler, making a mark point, then fixing the lower end of the line drawing rod 4 on the mark point, finally covering the central point of the opening 10 by using the support 1, enabling the folding line at the top of the support 1 to be parallel to the axis of the circular steel pipe 8, and adsorbing the device on the circular steel pipe 8 by using the magnet 2;
3. the adjusting arm 6 is rotated around the supporting rod 3, and the line drawing rod 7 is drawn up and down along the same trend, so that the lower end of the line drawing rod 7 is prevented from leaving the outer circumferential surface of the circular steel pipe 8, the line drawing is completed after rotating for a circle.
