Torsional spring in the middle part of torsional spring inserted link, so that the torsional spring on torsional spring inserted link is subject to shot-peening to impact, improves the practicality of torsional spring shot-blast unit
Property.
As more specifically scheme, the injection apparatus accommodating cavity is U-type groove, injection apparatus accommodating cavity and stent one into
Type.Shot-blast unit and the shot-peening accommodating cavity is integrally formed, and simplifies stent manufacture craft, improves stent producing efficiency.
As more specifically scheme, the opening of the injection apparatus accommodating cavity is towards rotating device.
As more specifically scheme, the injection apparatus includes injector and centrifugation motor, and the injector includes sphere
And injection channel, the injection channel are arranged at intervals along sphere circumferencial direction and connect sphere, shot-peening is stored in sphere, described
Centrifugation motor is connected with injector, and centrifugation motor drives injector rotation, and injector produces centrifugal force by the shot-peening edge in sphere
Injection channel is thrown away.The centrifugation motor drives injector rotation to produce centrifugal force, and the shot-peening positioned at sphere cavity is logical along injection
Road throws away impact torsional spring, and it is consistent to throw away the dynamics of sphere by centrifugation shot-peening, makes torsional spring that uniform dynamics can be subject to impact,
So as to lift the fatigue resistance of torsional spring.
As more specifically scheme, the driving device is connected with turntable, and driving device drives turntable rotation, torsional spring inserted link
Turntable is followed to rotate.
As more specifically scheme, the driving device is driving motor.
The beneficial effects of the utility model are as follows：
The utility model, torsional spring are nested with torsional spring inserted link and follow turntable to rotate, and avoid mutually winding between torsional spring, turn round
Spring is disassembled easily, and torsional spring is rotated with turntable, and the shot-peening that shot-blast unit sprays can impact torsional spring any surface, make torsional spring
Uniform force, so as to greatly improve the fatigue strength of torsional spring.
