Abstract

The invention belongs to the technical field of anchor rod rolling, and provides equipment and a technology for piercing and rolling an anchor rod integrally. The equipment for piercing and rolling the anchor rod integrally comprises a heating device and a piercing and rolling machine (9), wherein the piercing and rolling machine (9) comprises a front table, a main frame and a rear table; each roller comprises an inlet section roller (24) and an outlet section roller (25) which are nested on a roller shaft, and the inlet section roller (24) is in key connection with the roller shaft and is provided with a perforation section A, a diameter-reducing and wall-reducing section B and a diameter-fixing section C; each outlet section roller (25) adopts a structure driven by the rolled anchor rod to rotate and is provided with an inlet cone D and a thread forming section E; and the equipment further comprises a mandrel (12) matched with the rollers. According to the equipment and the technology for piercing and rolling the anchor rod integrally, the solid bar material is subjected to perforating, diameter reducing, wall reducing, diameter fixing and thread forming on the same rolling machine to obtain the finished product of the anchor rod, the production steps are reduced, the cost is reduced, and the anchor rod production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of anchor rod rolling, and provides an integrated equipment and process for piercing and rolling anchor rods. Background technique [0002] Bolts have huge uses in various fields such as geotechnical engineering, highways, hydropower, railways, etc. Especially in recent years, with the continuous increase in the investment in large-scale infrastructure projects in my country, and the large-scale construction of high-speed railways and expressways, their consumption will increase. greatly increase. [0003] The current anchor bolt production process is mainly formed by cold rolling of finished steel pipes. Generally, from the steel pipe to the formed anchor rod, there are roughly a dozen of the following processes: steel pipe → annealing → pickling → phosphating, saponification → cold drawing reduction → annealing - repeated cycles - anchor rod manufacturer → cutting → rolling Manufacture of anchor bolts→bun...
