Abstract
The production process of carbon steel and spring steel wire includes the following steps: 1. lead patenting treatment of steel wire material; 2. surface treating steel wire borax surfacing agent to form lubricating powder carrier for the stretching process; 3. performing 11-13 gates of continuous drawing of the steel wire in a turned cone pulley combination while using calcium-base lubricating powder in the first three gates and sodium-base lubricating powder in the rest gates and making the steel wire move in the speed lower than that of the cone pulley linear speed; and 4. regulating the turn height and diameter of the spring wire in an angle regulator to obtain the carbon steel and spring steel wire product. The present invention has the advantages of no need of phosphorizing the steel wire before stretching and easy electroplating of the spring steel wire.
Description
One, technical field
The present invention relates to a kind of production technology of spring steel wire, especially a kind of production technology of carbon steel and spring steel wire.
Two, technical background
At present, diameter both domestic and external is at the thin specification carbon steel and spring steel wire of 0.1-0.6mm, as cold tensile spring steel line, oil-temper spring steel wire and qin steel wire, generally adopt the production technology of wet type cold-draw, in this production technology, adopt traditional water tank drawbench to carry out steel wire and stretch line, make steel wire before stretching line, must carry out phosphatization earlier, and when stretching the spring steel wire of the thin specification of line after the phosphatization, often make phosphate coating invade the spring steel wire matrix, thereby destroy the original mechanical property of spring steel wire, strengthened the difficulty of spring steel wire and plating of articles thereof.
Three, technology contents
At above-mentioned shortcoming, the object of the present invention is to provide a kind of production technology of not destroying the original mechanical property of spring steel wire, being easy to the carbon steel and spring steel wire of spring steel wire and plating of articles thereof.
Technology contents of the present invention is: a kind of production technology of carbon steel and spring steel wire, and its production stage comprises:
(1), the steel wire raw material carries out the patenting processing;
(2), with the borax film agent steel wire is carried out epithelium and handles, make epithelium in stretching line process, undertake the effect of powdered lubricant carrier;
(3), the steel wire after the epithelium processing is imported inverted cone pulley group by the long-pending line tube of single shaft machine carries out the continuous powder stretching of 11-13 passage line, use calcium base powdered lubricant when stretching line in preceding 3 roads, each passage use sodium base powdered lubricant later on; The steel wire movement velocity will be less than or equal to the cone pulley linear velocity;
(4), the steel wire behind the powder stretching line adjusts the high jump and the circle footpath of spring wire by an eye modular angle degree adjuster, the product carbon steel and spring steel wire.
The technology that the steel wire raw material carries out the patenting processing is common process.
The tensile strength of steel wire raw material is at 1160-1240Mp, and its line footpath size is as one, and can not there be scratch on the surface.
The inverted cone pulley group that the present invention uses is two pairs of cone pulleys, every secondary tower wheel has 7-9 ladder, being in and stretching the preceding cone pulley of line mould is driving wheel, the cone pulley of stretching behind the line mould is a follower, and driving wheel plays takes out the line effect, and follower play the guiding role, stretch in the line process if cone pulley rotational line speed is decided to be V, the movement velocity of steel wire is decided to be B, and the steel wire movement velocity will be less than or equal to cone pulley linear velocity, that is: B≤V; Because the diameter of every secondary tower wheel strengthens step by step, the linear velocity between the contiguous two-stage is: r
N+1=v
N+1/ v
n=D
N+1/ D
nR in the formula
N+1---cone pulley linear velocity ratio;
V

N+1----n level, n+1 level cone pulley linear velocity;
D

N+1----n level, n+1 level cone pulley diameter;
Steel wire is every to be stretched line through a time and all will extend, and its lengthening coefficient is:
u
n+1＝A
n/A
n+1＝d
n 2/d
n+1 2
A
n, A
N+1----n level, n+1 road steel wire sectional area

N+1----n level, n+1 road steel wire diameter
For guaranteeing that stretch line carries out smoothly, every time lengthening coefficient u of steel wire
nMust be more than or equal to the speed ratio of cone pulley, otherwise steel wire will not break because of flow does not wait: u
n〉=r
n, u then
n/ r
n〉=1.
This shows that steel wire draws and slides simultaneously and exists in stretching line process, advanced in unison on cone pulley during steel wire and tightly, the time and unclamp and skid; Available slide coefficient (the J of slippage size
n) expression: J
n=u
n/ r

Inverted cone pulley wire drawing machine is except that last passage (K passage) is fricton-tight, and other passages all might produce slip, and every time slides all with the form passage transmission forward of continued product, that is:
J‘
n＝J
n*J
n+1*Jn+2***J
k-1
J in the formula
n'----n passage accumulation slide coefficient
J
n, J
N+1----n, n+1 passage slide coefficient
This shows, passage more before, accumulation is slided big more, in addition passage more before, the steel wire diameter is thick more, the wearing and tearing of prime cone pulley are more much bigger than the back level.Perfect condition is that every time lengthening coefficient equates with the cone pulley speed ratio, is referred to as the fricton-tight line of stretching.In fact because die size has deviation and uneven wear, often to rebuild after the cone pulley wearing and tearing, can't realize the fricton-tight line of stretching, can only be within the specific limits slippage control.Slide coefficient is excessive, accelerate the wearing and tearing of cone pulley, the steel wire surface is easily by plucking, slide coefficient is too small, can cause again to join model and enclose narrow and smallly, mould and die accuracy is required to add tight, often be difficult to accomplish, slide so only consider passage, do not consider the accumulative total slip, when joining mould the passage slide coefficient is controlled between the 1.015-1.04.
Should strengthen the u of last passage aborning
kAnd r
kRatio, with J
kBe controlled at about 1.10 slide coefficient (the J of other passage
n) being reduced to 1.0-1.01, the advantage of this method is: stay bigger leeway 1. for nib wearing and tearing of last several roads and dimensional discrepancy, can reduce die change number of times and tensile phenomenon.2. make full use of slip to front transfer, characteristic of accumulation, make before the K-1 passage cone pulleys at different levels that 10% rate that horizontally slips is all arranged, and do not have or little more accumulative total is slided, each passage is slided evenly, the loss of complete machine sliding ratio reduces, and cone pulley and filament surfaces wear phenomenon significantly reduce.3. each passage is reserved about 10% accumulative total slip, stays enough leeway for the increase and the deviation of mold hole dimension, can reduce die change number of times and tensile phenomenon.
The cone pulley speed ratio (r) of inverted cone pulley wire drawing machine is generally 1.2, and the final pass speed ratio is 1.17, adopts each passage to fix 17% draft.Accurately measure cone pulley diameters at different levels before joining mould, calculate each gear-stage velocity ratio (r
n), from finished size, press u

The advantage that the present invention had is:
(1), steel wire needn't carry out phosphatization before stretching line, thereby do not destroy the original mechanical property of spring steel wire, reduced the difficulty of spring steel wire and plating of articles thereof.
(2), can produce the qin steel wire of facet.
