Second step, independently two first spinning roller 3, second spinning rollers 5 with the single flute profile of target workpiece 6 outer surface are symmetrically placed in outside cylindrical blank 1, and identical with the position of first groove of target workpiece 6, the axis of the first core 2, second core 4, first spinning roller 3, second spinning roller 5 and cylindrical blank 1 is in same plane;
3rd step, keep the invariant position of the first core 2, second core 4, be inwardly fed to given groove depth, then feed-disabling by the first spinning roller 3, second spinning roller 5, treat more than cylindrical blank 1 triple turn, grooved form stable backed off after random first spinning roller 3, second spinning roller 5;
4th step, then spinning second race, first spinning roller 3, second spinning roller 5 is moved to and aligns with the second groove of the first core 2, second core 4, then given groove depth is inwardly fed to, then feed-disabling, treat more than cylindrical blank 1 triple turn, grooved form stable backed off after random first spinning roller 3, second spinning roller 5;
5th step, then carry out the spinning of lower one race, process is the same, repeats above process, until complete all grooved spinning;
6th step, and then from first race, by all grooveds spinning more than one time again, until grooved is stablized;
7th step, exits the first spinning roller 3, second spinning roller 5, shrinks the first core 2, second core 4, takes out target workpiece 6, completes process.
The grooved of described target workpiece 6 is V-type or semi-circular.
This spinning process also can use three cores, the mode of three spinning rollers is carried out, and wherein each core becomes hexagonal angle to distribute, and each spinning roller matches with each core and also distributes in 120 °, identical when technical process and twin-core mould, double rotary wheel.
This spinning process also can use the core of more than three and the mode of spinning roller to carry out, and spinning process is also identical with when twin-core mould, double rotary wheel.
The present invention has following beneficial effect:
One, higher working (machining) efficiency.This technique is than the working (machining) efficiency of traditional forging type significantly wheel of elevator belt grooved, and one-shot forming, eliminates all too many levels.
Two, higher economic benefit.Use less core to replace the monoblock type core used in conventional spun technology, not only reduce the cost of mould self, effectively extend the scope of application of same secondary core simultaneously.
