Abstract
The invention discloses a production technology of a supporting bolt. The production technology of the supporting bolt comprises the following steps of (1) wiredrawing processing after raw material primary checking, (2) cold heading processing, (3) cold heading wire rolling processing, (4) galvanization processing, and (5) final checking and delivery. The production technology is rigorous in step; the produced supporting bolt is good in quality, not prone to being damaged, long in service life and low in waste in the intermediate step; the waste raw materials are reprocessed, and therefore the production cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of earthquake structural engineering field, be specifically related to a kind of production technology of carrying bolt.
Background technology
Carrying bolt is that fundamental parts conventional in a kind of engineering field is used widely.The carrying bolt of producing in prior art in use, service life is shorter, often easily occur in use for some time the phenomenon of wear damage, and a variety of causes and the inspection of product of producing due to centre are not rigorous, make the quality of carrying bolt on the market can not be satisfactory.In addition, owing to there is the zincincation misoperation of intermediate steps, make the product situation that as easy as rolling off a log appearance is scratched in use, zinc-plated processing is relatively poor.And in production process, some are produced to underproof raw material as waste treatment, or reclaim after with waste and old product processing, caused very large waste, improved the production cost of enterprise.
Summary of the invention
The object of the present invention is to provide a kind of production craft step rigorous, the carrying bolt quality of production is good, is not easy to damage, long service life, and in intermediate steps, waste is few, and scrap feed material is reprocessed, and greatly reduces the production technology of the carrying bolt of production cost.
Technical scheme of the present invention is that a kind of production technology of carrying bolt, comprises the steps:
1) raw material is carried out to preliminary test, undesirable raw material is return, qualified raw material is carried out to wire drawing processing, process fine and smooth silking on raw material surface, afterwards the product processing is tested, by underproof waste treatment;
2) product qualified wire drawing is carried out to cold-heading processing, move forward with the heading pressing mold of cold headers, by the head extruding jumping-up of product, and rear spring pushes back pressing mold, loosen fixture, obtain the product after processing, afterwards the product processing is tested, by underproof waste treatment;
3) qualified product is carried out to cold-heading thread rolling processing, thread rolling is carried out at position by product except the head of jumping-up, makes product surface become spiral helicine groove screw thread, forms screw rod, afterwards the product processing is tested, will after underproof waste treatment, reprocess;
4) carry out zinc-plated processing selecting after qualified product, scrub zinc liquid at product surface, treat scrub after surface sizing, afterwards zinc-plated product after treatment is tested, reprocessing after will underproof product abandonment processing;
5) finished product finally obtaining is tested, will be underproof product abandonment process after reprocessing, qualified product pack after processing to go out to transport.
In a preferred embodiment of the present invention, in described step 2, the head diameter of the raw material jumping-up of carrying bolt is 13mm.
In a preferred embodiment of the present invention, in described step 3, the groove screw thread of screw rod is circular thread.
In a preferred embodiment of the present invention, described zinc-plated processing adopts hot dip galvanizing process to carry out.
Of the present invention is a kind of production technology of carrying bolt, and during the present invention produces, processing step is rigorous, and the carrying bolt quality of production is good, be not easy to damage, long service life, and in intermediate steps, waste is few, scrap feed material is reprocessed, greatly reduce production cost.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Of the present invention is a kind of production technology of carrying bolt, comprises the steps:
1) raw material is carried out to preliminary test, undesirable raw material is return, qualified raw material is carried out to wire drawing processing, process fine and smooth silking on raw material surface, afterwards the product processing is tested, by underproof waste treatment;
2) product qualified wire drawing is carried out to cold-heading processing, move forward with the heading pressing mold of cold headers, by the head extruding jumping-up of product, and rear spring pushes back pressing mold, loosen fixture, obtain the product after processing, afterwards the product processing is tested, by underproof waste treatment;
3) qualified product is carried out to cold-heading thread rolling processing, thread rolling is carried out at position by product except the head of jumping-up, makes product surface become spiral helicine groove screw thread, forms screw rod, afterwards the product processing is tested, will after underproof waste treatment, reprocess;
4) carry out zinc-plated processing selecting after qualified product, scrub zinc liquid at product surface, treat scrub after surface sizing, afterwards zinc-plated product after treatment is tested, reprocessing after will underproof product abandonment processing;
5) finished product finally obtaining is tested, will be underproof product abandonment process after reprocessing, qualified product pack after processing to go out to transport.
In described step 2, the head diameter of the raw material jumping-up of carrying bolt is 13mm.
In described step 3, the groove screw thread of screw rod is circular thread.
Described zinc-plated processing adopts hot dip galvanizing process to carry out.
In technological operation, reprocessing represents the substandard product in this step to pick out, and be processed into new qualified products by machining again, and due to the reason of wearing and tearing and reprocessing, the product that reprocessing is produced may, with the model difference of original product, belong to a new style number product.
Of the present invention is a kind of production technology of carrying bolt, and during the present invention produces, processing step is rigorous, and the carrying bolt quality of production is good, be not easy to damage, long service life, and in intermediate steps, waste is few, scrap feed material is reprocessed, greatly reduce production cost.
The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
