Heating electrode for reinforcement heated and upset end

Abstract

The invention discloses a heating electrode for a reinforcement heated and upset end. The heating electrode comprises an electrode bracket; a power device and a heating electrode are arranged on the electrode bracket; the power device pushes the heating electrode to move, or pushes the electrode bracket to drive the heating electrode to move; a slide column is arranged on the electrode bracket, and is provided with a spring; the front end of the spring is arranged at the back end of the heating electrode; the back end of the spring is fixed; and a spring located in a compression state applies the spring acting force to the heating electrode. The heating electrode is a floating form, continuously generates the thrust in the heating process, guarantees no release between the electrode and the end surface of a reinforcement due to heating softness of the reinforcement, is uniform and fast in heating, can prevent generation of electric sparks, is high in heating efficiency, only needs the time of about 2 seconds, and improves the machining efficiency.

Description

technical field [0001] The invention belongs to the technical field of thermal processing of steel bars, in particular to a heating electrode for heating and upset ends of steel bars. Background technique [0002] The bonding and anchoring performance between steel bars and concrete is a necessary condition to ensure that the steel bars and concrete work together. Therefore, it is necessary to ensure that the steel bars have sufficient anchorage lengths to ensure that the relevant performance of the reinforced concrete structure meets the requirements. However, due to the limitation of structural size, it is usually difficult to meet the required anchorage length of straight steel bars. Although the traditional mechanical anchoring method with hooks at the end has the advantages of simple manufacture and low cost, it is difficult to avoid the interference between the bent section steel bar and the straight steel bar. , resulting in difficulty in binding steel bars, especiall...

AI Technical Summary

Problems solved by technology

In this invention patent, firstly, the heating temperature is too high, which wastes energy, and the strength of the steel bar is too low at such a high temperature. When the compressive force P in the axial direction compresses the end area, it is easy to cause the steel bar end Bending, crooked head, rotten head, etc. affect the strength of the upsetting head
