Background technology
Elastic bar IV type fastener system is a kind of fastener system of the High-speed Passenger Dedicated Lines of China's independent research.Wherein C4 type spring is (because contour structures is " e " shape, therefore " e " type that is otherwise known as spring) be the core component of elastic bar IV type fastener, compared with the spring that other are similar, its buckle press maintenance, fatigue life, with the positive connection on basis and damping property etc. in, all there is better performance.The diameter of spring bar is 20 millimeters, and the moulding process of current domestic employing is mainly four punch formings, and need four punch presses and four molds, after four punch formings, the profile of workpiece is successively as shown in hereinafter accompanying drawing 1 to 4.
The deficiency adopting above-mentioned moulding process to process spring existence is:
1, molding procedure is many, and by adjustment, the impact that repeatedly shaping positioning datum is different of human factor, mould, the size fluctuation of product is large, uniformity is poor, and product first-time qualification rate is low.
2, punch press shaping speed is fast, the easy drawing-down of bar, the mechanical properties decrease of product.
3, molding procedure is many, and bar temperature declines many, and be unfavorable for immediate quenching, sometimes must reheat quenching, energy ezpenditure is large.
4, forming operation is complicated, and die adjustment is inconvenient.
5, production process is many, and equipment, mould have high input, and operating personnel are many, and production cost is high.
Summary of the invention
The present invention is just for the deficiency that prior art exists, a kind of high ferro spring is provided to be wound around machine-shaping device, can first three punch forming be changed into once Wrapping formed, reduce spring molding procedure, equipment, mould to reach, improve the object of the stability of product size, product quality and reduction production cost.
For solving the problem, the technical solution used in the present invention is as follows:
A kind of high ferro spring is wound around machine-shaping device, comprise: rotary main shaft, with be arranged at described rotary main shaft end face and be positioned at the Wound Dies at described rotary main shaft axle center place, described Wound Dies comprises the bar holddown groove for inserting bar and is arranged at the first projection and second projection of described bar holddown groove both sides, described first projection is arc-shaped transition towards the sidewall of the side in described rotary main shaft axle center and described bar holddown groove, and the side of described first projection described rotary main shaft is dorsad provided with arc groove; Also comprise the receipts limit pressure head and press-bending pressure head that are arranged at described Wound Dies both sides, described receipts limit pressure head and described press-bending pressure head are all arranged on linear actuator, can carry out straight line back and forth movement.
As the improvement of technique scheme, one end of described bar holddown groove is provided with bar stop bit projection, described bar stop bit projection comprises the installation portion towards the lug boss of side, described rotary main shaft axle center and described rotary main shaft side dorsad, and described boss is in described bar holddown groove.
As the improvement of technique scheme, the movement locus of described press-bending pressure head and the axle center conllinear of described rotary main shaft, the movement locus of described receipts limit pressure head and the axle center not conllinear of described rotary main shaft.
As the improvement of technique scheme, described receipts limit pressure head and described first projection are all positioned at the clockwise side in described rotary main shaft axle center or counterclockwise side.Described structure makes the arm of force of described receipts limit pressure head bending bar increase, and when moment of rupture is certain, thus is conducive to the bending function power reducing described receipts limit pressure head, thus reduces energy consumption and improve service life of described receipts limit pressure head.
As the improvement of technique scheme, described receipts limit pressure head comprises support component and rolling member, and described rolling member is located in the free end of described support component.Described structure makes described receipts limit pressure head and bar be Structure deformation, thus sliding friction is improved to rolling friction, improve the stationarity being wound around operation, reduce described receipts limit pressure head to the wearing and tearing of bar, improve product quality, reduce the wearing and tearing of bar to described receipts limit pressure head simultaneously, improve the service life of described receipts limit pressure head.
Another object of the present invention is to provide above-mentioned high ferro spring to be wound around the method for work of machine-shaping device, comprises the following steps:
Step one, bar one end is inserted in described bar holddown groove, then described receipts limit pressure head work is entered (namely moving towards described Wound Dies), and described rotary main shaft at the uniform velocity rotates until form coplanar inner side straight flange, middle part straight flange, outside straight flange, large arc-shaped side and little arc-shaped side;
Step 2, described receipts limit pressure head work are moved back (i.e. described Wound Dies motion dorsad), described rotary main shaft rotates, until the described arc groove of described first projection is towards described rotary main shaft axle center, then described press-bending pressure head work is entered, and forms the depression bending of middle part straight flange.
Compared with prior art, implementation result of the present invention is as follows in the present invention:
High ferro spring of the present invention is wound around machine-shaping device, can first three punch forming in prior art be changed into once Wrapping formed, namely adopt high ferro spring of the present invention to be wound around machine-shaping device only to need, by once Wrapping formed conjunction and one time punching molded two steps, the processing and forming of " e " type spring can be realized.It has the following advantages:
1, owing to rotating main motion uniform rotation, adopt rounding off between each curve, bar diameter is less by the size of drawing-down, and evenly, therefore the mechanical property of product is good.
2, reduce by two procedures, the operating personnel of use, equipment, frock, mould reduce, and reduce the accumulated error of human factor and operation, the uniformity of product size is more easily guaranteed.
3, forming process thermal loss is little, immediate quenching technique easy to use.
