1、When installing the wire roller of large thread rolling machine, the root of the wire roller should be wiped clean. When mounting and dismounting the wire roller, first remove the wheel rod support seat respectively, mount the wire roller on the wheel rod, and adjust the wire roller to the required axial position with the adjusting washer. The end faces of the two wire rollers should be adjusted to the horizontal plane as far as possible. The bearings of the wire roller and the support block are combined with washers to prevent axial movement of the wire roller.
2、Support block is mounted on the support seat, and the top of the large wire roller is welded with carbide. Loosen the fastening bolts of the support block, add or subtract shims at the bottom of the support block to adjust the height of the support block, and then tighten the bolts. The height of the support block plays an important role in the rolling compression process.
3, the width of the support block should be subject to the rolling wheel will not collide with the support block. For workpieces with diameters below M10, the width should be close to the permissible width. For workpieces with diameters above M10, the large thread rolling machine allows the width of the top of the support block to be larger, but it does not have to exceed 18mm.
Large thread rolling machine is mainly used for upsetting ribbed steel bars in construction works, and it is the key equipment for realising steel bar connection. It is used for steel bar connection works to ensure the quality of connection. Its function is to squeeze the head of the construction threaded steel bar to pier thickness, thus increasing the diameter of the head of the steel bar and increasing the tensile strength. The machine is easy to operate, fast and with high processing quality. It is mainly used in major projects such as construction, road and bridge, high-speed railway, underground, tunnel and demanding power station. Large wire rolling machine has: no pollution, no open flame, can be processed anytime, anywhere, shorten the period of work, urgent.
