Abstract
The utility model belongs to an improvement of a decoiler rotation drawbar structure for cold rolling pickling in a rolling mill, in particular to a decoiler rotation drawbar structure for cold rolling pickling, which comprises a decoiler drawbar, wherein the decoiler drawbar consists of a drawbar shaft and a shaft sleeve mounted on the drawbar; two annular bosses are arranged on the shaft circumference at one end of the drawbar shaft; the shaft sleeve is in interference fit with the two annular bosses on the drawbar shaft; fillet welded joints are arranged at the chamfered position at a shaft end, matching with a hole end of the shaft sleeve, of the drawbar shaft; and the drawbar shaft and the shaft sleeve are fixedly connected into a whole. The decoiler rotation drawbar structure for cold rolling pickling is reasonable in structure, not only can increase the strength of the drawbar and is safe and reliable to operate, but also can reduce manufacturing cost of the drawbar.
Description
Technical field
The utility model belongs to the improvement of steel rolling mill's cold-rolling pickling uncoiler rotating rod structure, particularly cold-rolling pickling uncoiler rotating rod structure.
Background technology
The uncoiling pull bar of steel rolling mill's cold-rolling pickling uncoiler is a vitals, bears following function:
1, drives reel of uncoiler harmomegathus;
2, rotate with reel.
The uncoiler pull bar of cold rolling pickling unit, repeatedly fracture was bearing holder (housing, cover) and pull bar one originally in the use
Structure, pull bar are very long, and the bearing holder (housing, cover) spot size is short and thick, makes former pull bar making blank one pluckings big other end elongated, makes elongated position forging quality and thermal treatment quality can not get ensureing, cause and rupture in the use, and cost of manufacture is very high.
Summary of the invention
The purpose of this utility model is to provide a kind of cold-rolling pickling uncoiler rotating rod structure, and it is rational in infrastructure, not only can improve pull bar intensity, and is safe and reliable, and can reduce the manufacturing cost of pull bar again.
The purpose of this utility model is achieved in that a kind of cold-rolling pickling uncoiler rotating rod structure, comprise the uncoiler pull bar, the uncoiler pull bar is made of the axle sleeve of installing on pull rod shaft and the pull bar, the twice annular boss is being set on the diameter of axle of pull rod shaft one end, twice annular boss interference fit on axle sleeve and the pull rod shaft, the chamfering place that the axle head of pull rod shaft matches with the axle sleeve nose end is being provided with filler weld, and pull rod shaft and axle sleeve are fixed as one.
The utility model uncoiler pull bar is by pull rod shaft and be installed in the axle sleeve of installing on the pull bar and constitute, the axle sleeve hot charging is arrived the pull rod shaft end, realize axle sleeve and pull rod shaft interference fit, and the chamfering place that the axle head of pull rod shaft matches with the axle sleeve nose end carries out fillet weld, pull rod shaft and axle sleeve are fixed as one, not only reduced the processing and fabricating cost, and reduced shaft shoulder stress and concentrated, do not have bigger shaft shoulder stress when making pull rod shaft bear big pulling force and concentrate, improved the intensity of pull bar.Fine through trial effect, fault-free takes place.Pull rod shaft of the present utility model selects for use the hot rolling bar to replace forging quenched and tempered steel, has improved the reliability of pull bar quality.The utility model is rational in infrastructure, not only can improve pull bar intensity, and is safe and reliable, and can reduce the manufacturing cost of pull bar again.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing, and accompanying drawing is the utility model structural representation.
The specific embodiment
A kind of cold-rolling pickling uncoiler rotating rod structure, as shown in drawings, comprise the uncoiler pull bar, the uncoiler pull bar is made of the axle sleeve of installing on pull rod shaft 1 and the pull rod shaft 12, twice annular boss 3 is being set on the diameter of axle of pull rod shaft 1 one ends, twice annular boss 3 interference fit on axle sleeve 2 and the pull rod shaft 1, the axle head of pull rod shaft 1 is being provided with filler weld 4 with the chamfering place that axle sleeve 2 nose ends match, and pull rod shaft 1 and axle sleeve 2 are fixed as one.Pull rod shaft 1 is by 42C
rM
oSteel hot rolling bar constitutes.Axle sleeve 2 is by 42C
rM
oThe forging forging piece constitutes.Axle sleeve 2 can utilize the off-axis bore hole at the position of former fracture pull bar installation shaft bearing sleeve to process.
