Description

Technical Field

[0001] The invention belongs to the field of welded pipe mold manufacturing, and in particular relates to a welded pipe mold measuring tool. Background Art

[0002] Welded pipes are generally formed using roller-type welding pipe dies to continuously produce steel pipes of certain specifications. The heating method adopts induction welding or contact welding, that is, a stainless steel strip of moving specifications is fed into the unit, and the steel strip is curled into a tube blank by the forming roller. Then, a high-frequency current is used to quickly heat the edge seam of the tube to the welding temperature, and the welding is completed under the extrusion of the extrusion roller. The tube is then cooled, sizing and roughly straightened to form a stainless steel pipe of the required specifications.

[0003] Traditional pipe welding dies are rollers with an axial through-hole at their center for fitting over the main shaft. The sides of the rollers are curved for forming the pipe. During use, the rollers' sides are easily deformed by the pressure of the pipe material. Existing roller dies cannot detect roller wear, and severe roller wear reduces the yield rate of steel pipes produced. However, ultrasonic probes for measuring roller wear require water coupling, making them inconvenient. There is a pressing need for a device that can quickly and easily detect the machining accuracy or wear of pipe welding dies. Summary of the Invention

The alignment groove 22 is aligned with the limit block 12 so that the measuring block 10 is mounted on the mounting shaft 6. Then, under the action of the counterweight 23, the measuring block 10 is rotated to a position where the detection plate 13 is horizontal. The bolts 16 of the positioning seat 7 are then locked and fixed to the mounting shaft 6 so that the positioning spring 9 elastically contacts the measuring block 10. The roll mold to be tested is placed vertically on the rotating disk 2. The moving seat 3 is then adjusted to a position where the detection plate 13 contacts the side of the roll. The lifting column 5 is then adjusted up and down to a height position where the detection plate 13 contacts the side of the roll to be tested. The roll is then rotated, and the change in the range of the position where the end of the measuring block 10 contacts the measuring scale line is observed to determine whether the outer circumference roundness and outer diameter of the roll are within a reasonable range, thereby measuring the processing accuracy and wear of the welded pipe mold. The present embodiment can conveniently detect the processing accuracy and wear of the welded pipe mold, thereby improving the detection efficiency. In order to facilitate the measurement of whether the height of the roller is within a reasonable size range, a measuring mechanism 24 is vertically provided on the lower side of the square shaft 6a of the mounting shaft 6.
