Description

Spring precise machining device
Technical field
The application is related to a kind of spring precise machining device, belongs to the processing that spring wire is manufactured by line substantially without cutting Or processing metal machinery technical field.
Background technology
Spring is the occasions such as mattress processing, spring mechanical, hardware appliance, for Generals culture, the processing essence of spring Degree requires not high, however, as consumer is to comfort(Such as mattress), mounting stability(Such as spring mechanical)Plus Work precision(Such as hardware appliance)It is required that the fine wire of more and more higher, especially below 0.5mm, common process equipment is very It is uneven to produce wire rod drawing, produces phenomena such as shaking, causes the wire rod not stablize and conveys, line sending length is uneven, makes adding During work spring, due to the precision that is unstable and reducing spring of wire rod.
Spring process is mainly summarised as:Steel wire is sent out by line sending frame, after alignment, preliminary elongational, delivers to wind spring work In sequence, after winding lopping, cut-out forms spring crude green body, and the processing of spring is completed in then post processing.Wherein, in alignment process In, usual manner is to move two roller bearings using certain one although to realize not as the alignment element contacted with steel wire, this mode With the processing of diameter wire, however, due to one dynamic certain in two roller bearings, the change of unilateral position, it is very easy to cause center The change of position, so that the different phenomenon of both sides alignment occurs in alignment process in steel wire, machining accuracy seriously reduces. And the conventional speed changing structure of duplicate gear spline slide is then used during line sending, exist be driven unstable spline slide, The defects of noise is larger;In the spring forming stage, it is supported and cuts by means of the mode of core knife movement, and conventional core knife is Locking is fixed by screw or helical screw, is cutting the moment of steel wire, cutting knife is very big to the impulsive force of core knife, causes core Easily there is the phenomenon that pitches in knife, and causes control not smart;Core pulling can not lock, and locking is unable to core pulling.
Based on this, the application is made.
