Description
Technical field
The present invention relates to a kind of saponification process technique for bolt class product.
Background technology
With China's high speed, heavy duty, the development of subway railway, on the railway of high speed development, rail fastening plays more next
More important effect, and bolt class product occupies larger specific gravity in fastener, bolt failure means that whole fastener failure, this
Major safety risks are produced to train travel.The quality requirement of high-speed railway is high, and construction cost is high, therefore raising product quality,
Reduce construction cost, improve production efficiency also just into one of our research directions.The mould of bolt class product in process of production
Tool service life and product quality also just become one of problem of our research and development.
We have to be understood that bolt product passes through produced problem in cold-drawn and the effect of contracting bar and its process first:
1st, cold-drawn:Exactly raw material are stretched by drawbench and mould, it is become the product required for us
Diameter dimension.If lubricant effect is bad, produced problem has:1. product appearance is easily pulled;2. linearity is easily overproof;③
Die wear is very fast;4. enhanced stretch resistance increases, equipment is easily damaged.
2nd, contracting bar:It is exactly that cold extrusion is carried out to product by forcing press and mould, it is become the rolled thread required for us
Preceding diameter dimension.If lubricant effect is bad, produced problem has:1. product appearance is easily pulled;2. linearity is easily overproof;
3. die wear is very fast;4. crush resistance increases, easily swollen thick, mould and equipment are easily damaged product.
The content of the invention
In order to overcome the disadvantages mentioned above of prior art, the invention provides a kind of saponification process work for bolt class product
Skill, by covering one layer of uniform saponified film of white on raw material surface, lubrication is played a part of to bolt product, so as to
So that in the production process of cold-drawn and contracting bar is carried out to bolt class product, before bolt shank diameter and rolled thread being met well
The requirement of diameter, the quality of bolt product is improved, while lubrication well and protection are also functioned to the production mould of bolt product
Effect, extends the mold use life-span.
The technical solution adopted for the present invention to solve the technical problems is:A kind of saponification process work for bolt class product
Skill, comprise the following steps:
Step 1: prepare concentrate:
(1) quick lime, butter or sheep oil, industrial soap and water are got all the ready for 100: 15: 25: 125 ratio in mass ratio;
(2) quick lime is first poured into dosage bunker, is then slowly added into required water, reaction adds industry fertilizer when emitting hot gas
Soap, butter or sheep oil, stirring is until be completely dissolved repeatedly;
Step 2: prepare saponification liquor:
(1) concentrate and water are got all the ready for 250: 6000 ratio in mass ratio;
(2) concentrate is first added in saponification liquid pool, is then slowly added into water, stirring is until be completely dissolved repeatedly;
Step 3: saponification process:
Raw material Jing Guo processing of rust removing are put into the saponification liquor that step 2 prepares, slight concussion, make materials statement
Face fully contacts with saponification liquor, places 10~20 minutes, then takes out drying or room temperature airing, it is ensured that there is covering on raw material surface
One layer of uniform saponified film.
Compared with prior art, the positive effect of the present invention is:
The present invention solves bolt class product in process of production, i.e., occurs in cold-drawn and contracting bar production process:①
Product appearance is easily pulled;2. linearity is easily overproof;3. die wear is very fast;4. crush resistance increases, product easily it is swollen it is thick,
The problems such as mould and equipment are easily damaged, at the same ensure that product requirement gauge diameter and rolled thread before diameter, in addition to mould
Serve lubrication and extend the effect of die life.After the saponification process technique for employing the present invention, spiral shell is substantially increased
The quality of bolt product, is effectively improved production efficiency, also saves substantial amounts of time and cost.
Embodiment
A kind of saponification process technique for bolt class product, including following content:
1st, the mass ratio of concentrate is pressed:100 (quick limes): 15 (butter or sheep oils): 25 (industrial soap): 125 (water)
Ratio is prepared, and the concentrate requirement prepared is deposited in concentrate pond and more than two weeks can just put into production use.
2nd, the method for preparing concentrate:Quick lime is first poured into dosage bunker, is then slowly added into required water, reaction emits heat
Butter (or sheep oil) and industrial soap (butter or sheep oil and industrial soap are cut into the thin slice that thickness is not more than 5mm) are added during gas,
Stirring is until be completely dissolved repeatedly.Should be noted that when water is added in lime prevents the too high caused potential safety hazard of temperature.
3rd, the mass ratio of saponification liquor is pressed:250 (concentrates): the ratio of 6000 (water) is prepared, it is desirable in saponification liquor pond
First plus concentrate, water is then slowly added into, stirring is until be completely dissolved, and saponification liquor is heated to (70~80) DEG C repeatedly.
4 and then being put into temperature by the raw material of processing of rust removing (blasting treatment) as in the saponification liquor of (75 ± 5) DEG C,
Slight concussion, makes raw material fully be contacted with saponification liquor, (10~20) minute standing time, then proposes that drying or room temperature are cool
It is dry, it is desirable to which that there are the uniform saponified films of white of one layer of (0.05~0.10) mm of covering on raw material surface.
5th, after there is one layer of uniform white saponified film of covering on raw material surface, it is possible to which raw material are ground
Slightly, the process such as cold-drawn, cut-out, contracting bar, die mould.
The present invention principle be:It is exactly to be carried out in strict accordance with the making raw material and configuration proportion of concentrate and saponification liquor first
Prepare, then made according to the manufacture craft of concentrate and saponification liquor.It is exactly during using saponification liquor, first in addition
Saponification liquor heated, and control the temperature of saponification liquor, make its temperature control in the range of (75 ± 5) DEG C, it is desirable to
Product surface has the uniform saponified film of white of one layer of covering.If the saponification of the too low raw material surface meeting accumulation of thick of temperature
Thing, waste is easily caused, if too high the saponified of raw material surface of temperature is lost from, then just do not have the work of lubrication
With.Only when product surface covers one layer of uniform white saponified film, the lubrication between mould and product just can guarantee that
Effect, reduce die wear, increase the mold use life-span, could preferably ensure the presentation quality and dimensional accuracy of product.
