Abstract
Disclosed is a two-wheel flexible spinning technology applicable to radial grooves of synchronous cog belt pulleys. The radial grooves of the synchronous cog belt pulleys are machined in a mode that two mandrels and two spinning wheels spin oppositely, the mandrels and the spinning wheels consistent with target workpieces are used for extruding billets, positions of the mandrels are not changed in the spinning process, and the grooves of the workpieces are machined through rotation and radial feeding of the spinning wheels. By means of the two-roller flexible spinning technology, different radial grooves of the synchronous cog belt wheels can be machined, the adaptability is high, the machining range can be expanded without replacing the mandrels and the spinning wheels, and the working efficiency is high.

In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of be applicable to synchronous cog belt wheel radial groove to wheeled flexible spinning technique, can realize the processing of different synchronous cog belt wheel radial grooves, and very strong applicability is arranged, can be in the situation that do not change core and spinning roller enlarges the range of work.
In order to achieve the above object, the technical scheme taked of the present invention is:
A kind of be applicable to synchronous cog belt wheel radial groove to wheeled flexible spinning technique, may further comprise the steps:
The first step, with independently two have with the first core 2 of the identical flute profile of target workpiece 6 inner surfaces, the second core 4 symmetries place tubular blank 1 inside, the first core 2, the second core 4 are contacted with the inner surface of tubular blank 1;
Second step, two the first spinning roller 3, the second spinning rollers 5 that have with the identical flute profile of target workpiece 6 outer surfaces independently are symmetrically placed in tubular blank 1 outside, the axis of the first core 2, the second core 4, the first spinning roller 3, the second spinning roller 5 and tubular blank 1 is in same plane, and the first core 2, the second core 4, the first spinning roller 3, the second spinning roller 5 bottom surfaces relative and tubular blank 1 are in sustained height, and this height is identical to the relative altitude of bottom surface with the flute profile of target workpiece 6;
The 3rd step made the first core 2 relative with the flute profile of the first spinning roller 3, and namely fully engagement is relative with the flute profile of the second spinning roller 5 with seasonal the second core 4, namely can mesh fully;
The 4th step, keep the first core 2, the second core 4, the first spinning roller 3, the second spinning roller 5 invariant positions, do not rotate, then the first spinning roller 3, the second spinning roller 5 are pressed into projected depth so that blank produces a shallow hole along the radially inside feeding of tubular blank 1, compression distance does not limit time rotational with the first core 2, the second core 4, and the first spinning roller 3,5 rotations of the second spinning roller drive the stable rotation of generation with tubular blank 1 and are as the criterion;
The 5th goes on foot, and then keeps the invariant position of the first core 2, the second core 4, removes the rotation constraint, till the first spinning roller 3, the second spinning roller 5 synchronous rotations, synchro-feed are extremely fitted fully with tubular blank 1;
The 6th step, after this state of the first core 2, the second core 4 remains unchanged, the first spinning roller 3, the second spinning roller 5 feed-disablings, but the first spinning roller 3, the second spinning roller 5 still keep rotational velocity constant, treat more than tubular blank 1 triple turn, after the deformation of tubular blank 1 is stable, stops the rotation of the first spinning roller 3, the second spinning roller 5 and withdraw from;
The 7th step, shrink at last the first core 2, the second core 4, take off target workpiece 6.
Described tubular blank 1 is selected straight tube part formula or drum-shaped piece, and tubular blank 1 selects to be suitable for the material of plastic working.
The present invention has following beneficial effect:
1) higher working (machining) efficiency.This technique significantly promotes the working (machining) efficiency of synchronous cog belt wheel radial groove than traditional mode of production mode, all too many levels are saved in one-shot forming.
2) higher economic benefit.Same secondary mould can carry out the radial slot processing of the synchronizing jugged belt wheel of different size, has reduced die cost.
