Ribbed steel bar six-line rolling device and production method thereof

Abstract

The invention discloses a ribbed steel bar six-line rolling device. The ribbed steel bar six-line rolling device comprises a welding machine case; correcting devices are arranged at the top of the welding machine case; an electric welding machine is arranged on one side of the correcting devices; a fixed set square is arranged at the top end of the electric welding machine; a bracket is arranged on the rear surface of the fixed set square; an electric supporting transverse rod is arranged on the right side of the welding machine case; fixed upright rods are arranged at the bottom of the electric supporting transverse rod; the arrangement of a sound absorbing plate can reduce the noises produced by the electric welding machine in a using process, the diffusion amount of the noises is reduced, and the comfort degree of employees in a working process is improved; the arrangement of an intelligent switch can control the elongating or shortening of an electric telescopic rod according to whether a machine starts or not so as to control whether the sound absorbing plate enters the welding machine case or not, so that the sound absorbing plate is prevented from dust falling in a daily placement process; and therefore, a sound absorbing effect of the sound absorbing plate is prevented from being affected adversely.

Description

technical field [0001] The invention belongs to the technical field of industry, and in particular relates to a six-wire splitting and rolling device for ribbed steel bars. Background technique [0002] Ribbed steel bars (that is, threaded steel bars) are designed to increase the gripping force (that is, the bonding ability) of steel bars and cement. In practical applications, HPB235 (that is, primary steel) has no ribs, while HRB335 (secondary steel) , HRB400 (third-grade steel) has ribbed general HPB235 (that is, first-grade steel) without thread, while HRB335 (second-grade steel) is rebar, and HRB400 (third-grade steel) is bamboo rebar, so The level of steel bars can be distinguished from the appearance and shape. [0003] The existing welding machine frame is usually made by welding several steel rods of different lengths. The welding process requires professional welding masters, and the welding process is time-consuming and laborious. The raw materials of the welding ...

AI Technical Summary

Problems solved by technology

[0004] The present invention solves the problem that the existing welding machine frames are usually welded by several steel rods of different lengths. The welding process requires professional welding masters, and the welding process is time-consuming and laborious. The raw materials of the welding frame usually need a fixed length. If the steel rods are of different lengths, they need to be cut or replaced, which will increase the welding workload and increase the cost. The welding machine is usually placed in an empty factory to work. When transporting steel bars, the steel bars and steel bars or There will be sound between the steel bar and the welding machine, and the noise will be amplified in the empty factory building, which will have a negative impact on the technical problems of the employees. Provide a six-wire split rolling device for ribbed steel bars
