Copper-clad steel grounding rod, manufacturing method thereof and lightning protection grounding device

Abstract

The invention discloses a copper-clad steel grounding rod, a manufacturing method thereof and a lightning protection grounding device. The manufacturing method comprises the steps of: selecting a copper pipe and a steel rod, and cleaning the inner surface of the copper pipe and the outer surface of the steel rod, so as to remove oil dirt on the inner surface of the copper pipe and an oxidized sheath on the outer surface of the steel rod; sleeving a steel rod with the copper pipe to form a copper-clad steel blank; heating the copper-clad steel blank; rolling, compressing and quenching the heated copper-clad steel blank; cutting off the rolled and compressed copper-clad steel blank according to a set diameter; and machining an external thread on the cut copper-clad steel blank to obtain thecopper-clad steel ground rod. The copper-clad steel ground rod is produced by adopting a hot rolling method manufacturing process; the steel rod is sleeved with the copper pipe through a sleeving method; physical combination of the copper and steel metal materials is achieved through rolling; a manufacturing process is environmentally friendly and free of pollution; the binding force of the copperand steel metal materials is higher; the grounding rod is higher in strength after being quenched; the grounding rod is not prone to bending in a construction process; and material cost can be effectively saved.

Description

technical field [0001] The invention relates to the technical field of lightning protection and grounding equipment, in particular to a method for manufacturing a copper-clad steel ground rod; the invention also relates to a copper-clad steel ground rod produced by the manufacturing method; Lightning protection grounding device for Baotou steel ground rod. Background technique [0002] The grounding rod is a kind of slender conductor with good conductivity. It needs to be hammered into the ground during construction. In order to avoid the grounding rod from bending during the hammering process, such as a lightning protection grounding rod disclosed in the Chinese patent whose publication number is CN208189802U, In fact, it is a lightning protection grounding device, which includes drill bits, several connectors, several copper rods (ground rods) and impact-resistant bolts. Several connectors and several copper rods form a connection unit, and several connectors and several c...

Problems solved by technology

[0003] In the prior art, the manufacturing process of electroplating and immersion plating is usually used to produce copper-clad steel grounding rods, and the electroplating manufacturing process is used to produce copper-clad steel grounding rods, which has the following problems: 1. Due to the residual electroplating solution in the finished material 2. It is difficult to increase the hardness of the ground rod; 3. Due to the electroplating process, only a thin copper layer (generally no more than 0.02mm) is plated on the surface of the steel core, and the copper layer is on the steel core. The adhesion on the surface of the core is poor. Therefore, during the construction of the lightning protection grounding device, the copper layer attached to the surface of the steel core is easy to fall off when the grounding rod is hammered and enters the ground.

[0004] Using the immersion plating manufacturing process to produce copper-clad steel grounding rods has the following problems: 1. The production energy consumption is large, the surface copper layer is uneven, and the production process must be continuous and uninterrupted; 2. The bonding layer of copper and steel is easy to form an alloy. It will cause the brittleness of the middle layer of the whole material to be high and easy to break
