Description
Technical Field
The utility model relates to a reinforcing bar cold drawing processing equipment, in particular to novel reinforcing bar cold drawing processing box.
Background
Cold drawing refers to a method of applying a drawing force on one end of a material to draw the material through a die hole, wherein the principle of cold drawing steel is that HPB 300-grade steel bar with the diameter of 6 ~ 8mm strongly passes through a specially-made tungsten alloy wire drawing die hole with the diameter gradually reduced at normal temperature to enable the steel bar to generate plastic deformation so as to change the physical and mechanical properties of the steel bar, as shown in figure 1, the cold drawing steel bar is to draw the steel bar through a hard alloy wire drawing die with the diameter smaller than the steel bar, the steel bar is subjected to the action of longitudinal tension and transverse pressure, the section is reduced, the length is lengthened, the strength of a steel wire is greatly improved, when the steel bar is cold drawn, the steel bar is subjected to plastic deformation by simultaneously tensioning and extruding, the section area of the drawn steel bar is reduced, cold work strengthening is generated, the tensile strength can be improved by 40-90%, the cold drawing process enables the material to have extrusion deformation besides the tensile deformation, the tensile strength and the compressive strength of the material can be improved, and the strength can be improved;
the cold drawing process comprises the following steps: heading → shucking → passing through a lubricant box → entering a wire drawing die hole; the heading is carried out on a heading machine, and the purpose is to thin the end of the reinforcing steel bar so as to pass through the wire drawing die hole; the husking is to remove hard slag shells on the surfaces of the steel bars by 3-6 rollers which are arranged up and down, and the lubricant is usually prepared by lime, animal and vegetable oil, soap, white wax and water according to a certain proportion; the iron slag can not enter the hole of the wire drawing die through shelling and lubricant, so that the service life of the wire drawing die is prolonged, and the phenomenon that the surface of a steel wire is scratched due to the iron slag in the hole of the wire drawing die is eliminated; after husking, the reinforcing steel bars are lubricated by a lubricant box and enter a wire drawing die hole for cold drawing.
In the actual production process of our company, it is found that in the existing wire drawing box for cold drawing of steel bars (the structural cross-sectional view of which is shown in fig. 2), the steel bars are lubricated by a lubricant box and then directly enter a wire drawing die hole for cold drawing, and the lubricant (wire drawing powder) and rust often appear and enter the wire drawing die hole and then extrude the steel bars to cause the wire drawing machine to stop and block; therefore, the inventor improves the existing wire drawing box, develops a novel steel bar cold drawing processing box, and adds a buffer space between a lubricating agent box and a wire drawing die hole, so that the novel steel bar cold drawing processing box has the advantages that (1) the lubricating agent (wire drawing powder) can be recycled for reuse; (2) the stop and the locking of the wire drawing machine caused by extruding the steel bar by the lubricant (wire drawing powder) and the rust are avoided; the practical use effect is very good, and the problem of machine halt and jamming basically cannot occur in the production process; the amount of lubricant (wire-drawing powder) is also reduced.
