Abstract

The utility model relates to a forming device of belleville spring, it is even as an organic whole with the die carrier on mould and lower mould, and the tapering of this last mould and lower mould slightly is greater than the tapering of the belleville spring that will process for upper and lower mould only contacts with belleville spring's interior excircle, and is equipped with the stop gear who controls upper and lower mould relative position among the forming device. The utility model discloses reducible forming die's quantity removes from and repaiies the mould process, shortens manufacturing cycle, improves production efficiency.

Description

Line contact disk spring building mortion

The utility model relates to the building mortion of disk spring, belongs to disk spring manufacturing technology field.

Existing disk spring manufacturing process is placed on the flat base of annular on upper and lower two conical molds and is shaped.Disk spring is that face contacts with the mould conical surface during shaping.The height of disk spring depends on the cone angle of shaping dies.Because disk spring has certain springback capacity after being shaped, the size of springback capacity can't be given earlier and being determined, therefore, the cone angle of finishing die also is difficult to determine, present way is that the cone angle of first figuration mould tries to be shaped according to the springback capacity of disk spring drawing height that requires and the disk spring of estimating to be shaped, cone angle by means correction finishing dies such as car, mills with the aspect ratio of the height of test specimen and requirement, again.Generally need to be shaped and repeatedly to repair a die can only be shaped a kind of disk spring of specification of a mold through examination repeatedly.

The purpose of this utility model provides a kind of disk spring building mortion of line contact.Need not repair a die with this device, and can the be shaped disk spring of plurality of specifications of a mold.

Technical solution of the present utility model:

A kind of line contact disk spring building mortion, it includes patrix 1 and counterdie 2, patrix 1 and counterdie 2 are connected as a single entity by mould bases 3, it is characterized in that the tapering of patrix 1 and counterdie 2 is slightly larger than the tapering of disk spring to be processed 4, make 1,2 of upper and lower moulds contact, and be provided with the position-limit mechanism 5 of upper and lower mould 1,2 relative positions of control in the building mortion with the inside and outside circle of disk spring 4.

The utility model can reduce the quantity of shaping dies, removes the process of repairing a die from, shortens the manufacturing cycle, enhances productivity.

Fig. 1 is a structural representation of the present utility model.

As Fig. 1, position-limit mechanism 5 of the present utility model can be liftable limited post, and its lower end is fixed on the middle part of counterdie 2, and its upper end is corresponding with the working face medium position of patrix 1.During work, as long as according to factors such as the processing request of the disk spring of being processed 4 and springback capacities, position-limit mechanism 5 is set up at level altitude, limited mechanism 5 was withstood when then patrix 1 affacted certain altitude, had guaranteed the processing request of disk spring 4.For some the fixedly processing of the disk spring 4 of specification, also single fixing spacing the drawing of its position-limit mechanism 5, need not make lift adjustment,, control the deflection of disk spring with this as long as selected its height determines to have the relative position of the upper and lower mould 1,2 of the conical surface.In forming process, the inside and outside circle of disk spring 4 and upper and lower mould 1,2 remain the line contact condition, and disk spring 4 conical surfaces do not contact with mould.Contact the disk spring of the multiple size that can be shaped by the flat base of disk spring and mould conical surface different parts.

Embodiment 1, shaping outer diameter D=50mm, and inner diameter d=25.4mm, height H=4.9, the disk spring 4 of thickness δ=3.5 is placed on the flat base of this disk spring on the mould, needs only this flat base in the upper and lower mould conical surface, and the method for same available embodiment 1 is shaped.

Claims

1, a kind of line contact disk spring building mortion, it includes patrix 1 and counterdie 2, patrix 1 and counterdie 2 are connected as a single entity by mould bases 3, it is characterized in that the tapering of patrix 1 and counterdie 2 is slightly larger than the tapering of disk spring to be processed 4, make 1,2 of upper and lower moulds contact, and be provided with the position-limit mechanism 5 of upper and lower mould 1,2 relative positions of control in the building mortion with the inside and outside circle of disk spring 4.

2, by the described line contact of claim 1 disk spring building mortion, it is characterized in that described position-limit mechanism 5 can be liftable limited post, its lower end is fixed on the middle part of counterdie 2, and its upper end is corresponding with the working face medium position of patrix 1.

3, by the described line contact of claim 1 disk spring building mortion, it is characterized in that the also single fixing limited post of described position-limit mechanism 5, it still is fixed on the middle part of counterdie 2.
