Abstract
The invention discloses an anchor ring manufacturing method which is characterized by consisting of the following steps that (a) waste steel is heated to 1700DEG C until that the steel is fully molten; (b) metal element ingredients are additionally arranged in the molten steel by a certain ratio; (c) the molten steel is poured into a mould, the molten steel is initially extruded after being cooled down to 1100DEG C and cold set, so that the tissue of the molten steel is changed; (d) an inner hole is extruded after a blank is fully cooled, so that the whole blank is hardened and formed; and (e) surface treatment and sand blast for oxidation treatment are carried out. The invention provides the improved anchor ring manufacturing method, so that a traditional process is changed without round steel or heat treatment, procedures are reduced and the cost is reduced. Meanwhile, the invention has the advantages of waste utilization and good mechanical properties.
Description
Technical field
The invention belongs to anchor circle manufacture field, specifically is a kind of to anchor circle preparation method and processing mold.
Background technology
The anchor circle belongs to bridge member prestressing force product; Such as positive 9 hole circle anchor circle materials is 45 steel or 40Cr steel; Use amount is big; 9 hole circle anchor circle conventional production process are that machined is shaped, and production process is: blanking → face work, cylindrical → brill straight hole (hinge taper hole) → modified → hinge taper hole → check → zinc-plated → warehouse-in.Many and the dense distribution owing to the hole, the lost time of holing, ream is more, and cutter consumption is big, and cost is higher, and the making of anchor circle is very loaded down with trivial details, expense is high, so need improve so this method of use is carried out.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective provides a kind of anchor circle processing and fabricating method of being convenient to operate at this, utilizes that refuse, operation reduce, production cost is low.
The present invention is achieved in that a kind of anchor circle preparation method of structure, it is characterized in that: may further comprise the steps:
A, be heated to 1600-1700 ℃ to steel scrap it is melted fully;
B, fusing molten steel add the metallic element batching in the 0.1-0.2% ratio;
C, molten steel is poured in the mould, treated that molten steel cools to 1000-1100 ℃ of condensation carry out just squeezing after solid, make it change its tissue and size;
D, treat to push endoporus again after blank cools off fully, make its whole hardened forming;
E, it is carried out surface treatment, surface sand-blasting carries out oxidation processes.
According to a kind of anchor circle preparation method according to the invention, it is characterized in that: zinc-plated again as protective layer after surface sand-blasting is carried out oxidation processes.
According to a kind of anchor circle preparation method according to the invention, it is characterized in that: institute adds metallic element batching for violent, silicon etc.
A kind of mould of realizing said method is characterized in that: mould is provided with a circular pedestal, fixedly is formed with a plurality of circular pillars in this circle pedestal.
According to a kind of mould of the present invention, it is characterized in that: be fixed with 4 said circular pillars in the circular pedestal
According to a kind of mould of the present invention, it is characterized in that: be fixed with 9 said circular pillars in the circular pedestal.
The invention has the beneficial effects as follows: the present invention provides an Artenkreis processing and fabricating method through improvement, without heat treatment, changes conventional machining process without round steel, saves cost, operation reduction.Advantage such as twice laid simultaneously,, mechanical property are good.
