Problems solved by technology
[0004] Since the inner and outer sides of the spiral tube coil need to be welded by high frequency, flux will be used in the welding process, and the flux will be sprinkled on the welding position, but the flux will melt into welding slag when it is subjected to high temperature, and the welding slag cannot be repeated It can be used, but it will stick to the welding position, and the welding slag and residual flux on the inner wall of the tube will accumulate inside the spiral tube, which is difficult to remove

The invention discloses a slag dumping machine for spiral pipes, which relates to the technical field of spiral pipe processing. The ring and the slide are provided with a clamping movable ring, the peripheral wall of the clamping fixed ring is hingedly connected with a plurality of locking rods, the locking rods are provided with a chute, and a lock block is slidably arranged in the chute, and the clamping movable ring is hingedly connected There are a plurality of connecting rods corresponding to the lock blocks one by one, the end of the locking rod is rotated with a pressing wheel, a swivel ring is coaxially rotated in the clamping ring, and an elastically arranged support plate is embedded in the swivel ring . By clamping and positioning one end of the spiral tube, the stability of the spiral tube is ensured, and then the spiral tube is lifted and rotated to quickly discharge the welding slag inside the spiral tube. The welding slag on the inner wall of the spiral tube automatically falls off, and the discharge speed is fast and stable, which improves the efficiency of the spiral tube finishing.
Description
technical field [0001] The invention relates to the technical field of spiral pipe processing, in particular to a slag dumper for spiral pipes. Background technique [0002] Spiral pipe is a relatively common type of steel pipe, which is made by rolling a low-carbon structural steel or low-alloy structural steel strip at a certain helical angle (called a forming angle) into a pipe blank, and then welding the pipe seams. , it can produce large-diameter steel pipes from narrower strips, and its uses are very extensive. [0003] The processing technology of the spiral tube includes: raw material inspection - uncoiling - initial flattening - cutting head butt welding - fine flattening - milling edge - delivery - forming internal and external welding - welding slag removal and external inspection. [0004] Since both the inner and outer sides of the spiral tube need to undergo high-frequency welding, flux will be used during the welding process, and the flux will be sprinkled on...
