Abstract
The present invention relates to a manufacturing method of a spring washer. The method uses hard steel wire materials with high hardness and toughness, the materials are formed and rolled into a rectangular or trapezoidal cross section in secondary high accuracy by a bi-planar roller and a four-surface roller, the hard steel wire is curled into the shape of continuous coils by the fore processing step and a post processing step under the action of three rollers with axial force. One of the three rollers is a driving roller and the other two rollers are driven rollers. When the spring washers are cut one by one, the spring washer blanks with the shape of continuous coils are slightly shifted and rotated. Finally, the processing of bluing and heating or electroplating is carried out.
Description
The present invention and cross section are that the manufacture method of rectangle or trapezoidal novel spring packing ring is relevant.
In the past, spring washer is with following method manufacturing, promptly low with hardness, toughness is little, for example carbon content is higher than 0.60% high charcoal steel wire, handle through soft annealing, be processed into the steel wire of the softening odd-shaped cross section of required specification again with the anti-wire drawing of difform mould, again with this steel wire coil coiled coil shape, and cut off 1 mode by 1 pitch it is cut into the blank of spring washer, to make the spring washer blank like this quenches continuously, the annealing heat treatment process, make it have satisfactory reference value hardness, it is carried out the heat baking after zinc-plated again and remove the hydrogen that infiltrates when zinc-plated so that eliminate fragility.So just produce the final products of spring washer.
Yet, a kind of manufacture method of easy spring washer is disclosed recently, promptly use the big hard wire of hardness height, toughness under suitable shrinkage, directly carry out the hot candied processing of abnormity in cold worked mode, again through reeling, cut off operation and make the spring washer blank of the shape that requires, with the internal stress of sending out heat treatment blue and eliminating in the above-mentioned blank, through plating.So just produce needed spring washer.
And this manufacture method, though in the special public clear 56-3891 communique of Japan, confirm to omit the advantage of the heat baking treating process after zinc-plated, openly in this communique how hardness height, hard wire that toughness is big are not carried out wire drawing and process, how to carry out abnormity processing, how the processing of how reeling cuts off processing.
Disclosed just hard wire, promptly high charcoal steel wire carries out the lead bath hardening heat treatment process to it and processes and obtain product with wire drawing as raw material, reaches the concrete way of handling about lead bath hardening.
Therefore, just with the material of hardness height, spring washer that toughness is big, promptly make the method for spring washer with hard wire, at present, each manufacturing firm is as develop working machine and transfer the possession of this machinery relatively secretly.
, the machinery that uses in the various uses, instrument are just tending to advanced, high precision int at present, so industrial circle appeals that consumingly spring washer wants high quality, a large amount of production and cost degradation.
No matter the objective of the invention is for realizing that above-mentioned requirements provides a kind of is use hard wire, still be to use Stainless Steel Wire, various raw material high efficiency such as phosphor bronze, low cost, make the method for spring washer accurately.
The present invention uses high charcoal steel of handling through lead bath hardening and the hard wire that obtains through wire drawing, hardness and toughness with Stainless Steel Wire or phosphor bronze etc. are carried out high-accuracy shaped rolling processing than higher wire, be wound into the processing of coil shape again, cut into spring washer blank one by one again, then with the elimination of sending out blue heat treatment stress in the spring washer blank that above-mentioned a series of machinings process and zinc-plated etc. electroplating processes.So just can produce the spring washer of the size that requires.
High-accuracy shaped rolling processing method is partly combined by two running roller rolling processing parts and four sides running roller rolling processing, at first to have left and right sides face be flat steel wire lead-in wire for circular steel wire raw material are processed into two running rollers with the cross section, then directly rolls wire drawing accurately with running roller on four sides and process desired rectangular or trapezoidal cross-sectional shape.
The coiling processing method usually, has the support mechanism that is made of three rollers in the manufacturing procedure of coiling coil, in three rollers, one is driving wheel, and remaining two is follower, and they all are pressed against on the external diameter of spring washer blank of coiling.Especially three rollers with support mechanism clamp driving spring packing ring blank external diameter, when the spring washer blank of reeling is sent, because each roller is bearing in the periphery of spring washer blank with the axle that is parallel to the spring washer blank that is sent, and it is free to rotate, also can on the sense of rotation of continuous reeling spring washer blank, produce driving force, and when the spring washer blank of reeling is sent not clamping place at the coiled type external diameter of the spring washer blank that is moved produce axial force.So just can produce high-precision continuous coiled type spring washer blank.
Cut off processing method, the spring washer blank that is about to long coiled type cuts into spring washer blank one by one.Coincidence and other spring washer blank generation chain lock for anti-upper spring packing ring otch, the position that the spring washer blank of rotating coil shape moves otch in cutting-off process is so that form a certain amount of micro-gap between two sections of a spring washer blank.
To obtain the spring washer blank through above-mentioned a series of machining process and send out heat treatment blue and eliminate its internal stress with conventional, zinc-plated again.So just can produce a large amount of desired spring washers.
Advantage of the present invention is that high-accuracy shaped calendering process is divided into the twice hot candied processing of abnormity, thus be fit to cold working, and can high-accuracy high-efficiency rate ground processing rectangular section or trapezoidal cross-section with the four sides running roller.Because two running rollers are little with the wearing and tearing of four sides running roller, thus the number of times of changing running roller reduced, so good operability; Because in the processing method of reeling through the hot candied spring washer steel wire of abnormity, order is pieced together the coiled type spring washer blank tightly wind with three roller wheel bearings and send, therefore there is not responsive to axial force on above-mentioned spring washer blank, needn't worry spring washer blank outer surface and be damaged, so can guarantee the quality of product height; Because in cutting-off method, whenever cut a spring washer blank and long coiled type spring washer blank will be done once small displacement rotation, so can between two sections of a spring washer, form micro-gap, thereby avoid the coincidence of otch and produced chain lock with other spring washer blank.Send out heat treatment blue through low temperature and just can produce high-precision spring washer.
