Description
Technical Field
The invention relates to the technical field of waste steel wire rope recycling, in particular to a waste steel wire rope or steel strand shot-cutting processing method and complete equipment.
Background
The steel wire rope is of a multi-strand spiral winding structure, steel wires in each strand are also wound into strands in a spiral winding mode, the steel strand is spirally wound together by a plurality of steel wires, and the structure of the steel wire rope is the same as that of the strand of the steel wire rope; in comparison, the wire diameter of the steel wire rope is generally thin, and the wire diameter of the steel strand is thick. The steel wire rope and the steel strand are widely applied in various fields of industrial and agricultural production and building electric power. However, after the steel wire rope or the steel strand is used for a certain service life, the steel wire usually breaks, the steel wire rope may also break or break, and after the steel wire rope or the steel strand breaks, the whole steel wire rope or the steel strand can only be replaced and discarded to ensure the use safety. Therefore, in long-term production practice, a large amount of waste steel wire ropes are necessarily produced, and the recycling of the waste steel wire ropes or steel strands also has important social significance and economic significance. The existing utilization mode is to cut steel wire ropes, steel strands or raw wires into small sections to form steel wire shots, and the shot cutting products can be widely applied to sand cleaning, rust removing, strengthening, forming, stress relieving, surface cleaning of various sectional materials, roughness (galling) pretreatment before coating and electroplating and the like in various fields.
Most of the existing steel wire shot cutting equipment adopts a blanking or cold heading equipment structure, and adopts a manual feeding mode to feed, so that the feeding port is single, the shot cutting efficiency is low, the labor intensity is high, and the safety is poor. In addition, the steel wire rope or steel strand cutting shot firstly needs to be split into single strands, or the steel strand is split into single steel wires and then cut into strands or split into filaments and then cut off. In the process of splitting the steel wire rope or splitting the steel strand, because the steel wire rope and the steel strand are both in a spiral winding structure, when splitting, the steel wire rope or the steel strand needs to be reversely twisted and drawn to form a strand or a single steel wire, and therefore the steel wire rope or the steel strand needs to be fixed to be successfully split. The existing fixing mode is that one end of a steel wire rope or a steel strand is fixed through a clamping device, and a steel strand or a free section of a single steel wire is reversely twisted, so that the steel wire rope or the steel strand needs to be integrally cut or stamped and sheared into small sections before being split, the efficiency is low, and the cutting or the stamping and shearing needs high-power equipment to cause a large amount of power consumption, which is contrary to the environmental protection idea. Therefore, a method and a complete set of equipment for carrying out shot cutting processing on waste steel wire ropes or steel strands are needed.

Wherein, the rust removal can adopt two modes of chemical rust removal and mechanical rust removal; the chemical rust removal can adopt an acid pickling mode to remove rust and can also adopt flame oxidation to remove rust; the mechanical rust removal comprises rust removal in modes of sand blasting, shot blasting or steel brush rolling brush and the like, and can be selected and used according to environmental conditions, resource conditions, environmental protection and energy conservation concepts and economic principles. When the method is used for treating the waste steel wire ropes or steel strands, the disorderly accumulated waste materials need to be straightened, the waste materials are treated by the method in a straightened state, or can be wound into a coil and then treated by the method, wherein the waste materials with oil stains are comprehensively determined according to the serious condition of the oil stains and a derusting facility, the oil stains are serious, and when no online derusting facility exists, the oil stains are preferably removed before the waste materials are treated by the method, the oil stains are light, and when the acid pickling method is used for derusting, the oil stains can be removed by using a neutralization tank after the acid pickling method.
In order to achieve the second object, the invention adopts the following technical scheme.

The implementation can realize the work circulation mode of long-time braking and short-time free rotation of the guide cylinder, and can save the electric energy consumption.
Obviously, when short braking and long free-wheeling duty cycle modes are required, the action of the electromagnet and the elastic element can be interchanged to reduce power consumption.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
