Description
Technical field
The utility model relates to the technical fields of stamping equipment, more specifically, it relates to a kind of diaphragm spring stamping die
Tool.
Background technique
Diaphragm spring is that one kind is designed to mitigate impact, absorbs the disc spring that vibration etc. needs to store great number of elastic potential energy,
It has a wide range of applications in automotive field.Diaphragm spring is in the manufacturing, first by sheet-metal press working at the film of disk type one by one
Piece, then diaphragm is subjected to heat-treatment quenching, diaphragm is finally pressed into three-dimensional cone structure, diaphragm is made to be provided with camber of spring function
Energy.
In the prior art, diaphragm spring carries out punch forming to high-intensitive plate using stamping die in the manufacturing,
Primary structure is as depicted in figs. 1 and 2, including rack 100, and the upper die component 200 and lower mold assemblies that are arranged in rack 100
300, upper die component 200 includes upper padding plate 210 and the punch-pin 220 being fixed on upper padding plate 210, under lower mold assemblies 300 include
Backing plate 310 and the cavity plate 320 being fixed on lower bolster 310, the punch-pin 220 and cavity plate 320 are mating, the rack
Driving upper die component 200 is additionally provided on 100 to the driving mechanism 400 moved close to lower mold assemblies 300, the driving mechanism
400 include hydraulic cylinder, and hydraulic cylinder bottom is fixedly connected on 100 top of rack, the telescopic rod and upper padding plate of hydraulic cylinder by screw
210 tops are fixedly connected by screw, and by being used cooperatively for cavity plate 320 and punch-pin 220, plate is pressed into disc one by one
The diaphragm of formula.
Prior art among the above has the following deficiencies: upper die component in downward punching press plate, to rush plate
Pressing formation can have huge impact force, make sheet metal forming, but plate is also due to impact force is excessive, and generates deformation,
The quality for influencing punching press diaphragm, improves production cost.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of stamping die for diaphragm spring,
By, from the multiple punch-pin for being short to long setting, first carrying out preliminary punching press along transmission direction length to plate, generating dent, then not
In disconnected transportational process, dent is constantly deepened, and plate is finally pressed into the diaphragm of disk type one by one, is repeatedly rushed to plate
It is molded, plate is avoided since impact force is excessive, and deformation is generated, the quality of diaphragm punching press is improved, reduces and is produced into
This.
To achieve the above object, the utility model provides following technical solution:
A kind of stamping die for diaphragm spring, including rack, and upper die component and lower mold assemblies are set in rack, it is described

Spring, and setting is pasted in 231 slot bottom of locating slot in 232 one end of elastic component, the other end, which is pasted, to be arranged on locating piece 233, and its
Original state is elongation state.
Referring to Fig. 6, for the fix tightly solidity for improving positioning component 230, locating piece 233 is close to 213 opening of rotation slot
One side wall is obliquely installed.
Referring to Fig. 4 and Fig. 6, and for convenience of the installation and removal of punch-pin 220, it is provided on the lower surface of upper padding plate 210
Through-hole 235, through-hole 235 are correspondingly arranged with locating piece 233, and are communicated with rotation slot 213.For further increase punch-pin 220 with it is upper
The fastness connected between backing plate 210, is provided with fixing bolt 236 in through-hole 235, and fixing bolt 236 passes through through-hole 235 and fixed
Position hole 234 is threadedly coupled.Meanwhile also being pasted in rotation slot 213 and being provided with elastic rubber layer, to punch-pin 220 and upper padding plate
Junction between 210 is protected, and the job stability of equipment is improved.
The course of work:
When suppressing plate, first by the link block 221 being arranged on punch-pin 220 be arranged in it is locking in mounting groove 211
Slot 212 aligns, and pushes punch-pin 220,220 grafting of punch-pin is entered in mounting groove 211, locking groove 212 is plugged on locking groove 212
In, when 220 top of punch-pin is inconsistent with mounting groove 211, punch-pin 220 is rotated, the link block 221 being arranged on punch-pin 220 is made
It is moved along 213 length direction of rotation slot to 213 slot bottom of rotation slot.
When link block 221 moves at 233 position of locating piece, 221 front end of link block can generate one to locating piece 233
The power for moving it to slot bottom along 231 length direction of locating slot, thus move locating piece 233 to 231 slot bottom of locating slot, elasticity
Part 232 is compressed.When link block 221 and 213 slot bottom of rotation slot are inconsistent, the location hole 234 of link block 221 is sitting at positioning
231 lower section of slot, locating piece 233 is due to being no longer influenced by the power for moving it to slot bottom along 231 length direction of locating slot, elasticity
The elastic potential energy of part 232 is released, and generates the power for making it do remotely located 231 slot bottom of slot movement to locating piece 233, from
And it is connected to locating piece 233 in location hole 234.Fixing bolt 236 through-hole 235 is passed through again to be threadedly coupled with location hole 234,
Punch-pin 220 to be fixed.
And during installation, according to the thickness of plate, the number of punch-pin 220 is adjusted, makes plate when moving along transmission direction,
It moves at the last one 220 position of punch-pin, plate ability compression moulding.
At work, by being used cooperatively between cavity plate 320 and punch-pin 220, in the huge impact force of upper die component 200
Under, a huge shearing force can be formed on plate, and plate is pressed into the diaphragm of disk type one by one.At least two it is convex
Mould 220 along plate transmission direction length from long setting is short to, so that the shearing force between punch-pin 220 and cavity plate 320 is changed.
The punch-pin 220 most inboard positioned at transmission direction cooperates the shearing force of generation minimum between cavity plate 320, makes since length is most short
The impact force generated to plate is minimum, has only carried out preliminary punching press to plate, has formed a dent on plate.It is constantly transporting again
In the process, dent is constantly deepened, and plate is finally pressed into the diaphragm of disk type one by one.
It realizes and Multi-step forming molding is carried out to plate, avoid plate since impact force is excessive, and generate deformation, improve
The quality of diaphragm punching press, reduces production cost.Simultaneously as it is not necessarily to one-pass molding, upper die component 200 in each punching course
Provided impact force also declines, and reduces the rigid collision between upper die component 200 and lower mold assemblies 300, improves upper mold
Component 200 and 300 service life of lower mold assemblies.
When punch-pin 220, which is broken, more to be renewed, the vertical bar that one is less than 235 diameter of through-hole is passed through into through-hole 235, will be determined
Position block 233 ejects location hole 234, and in rotation punch-pin 220, link block 221 is turned over to certain angle, makes locating piece 233 and determines
Position hole 234 separates, and facilitates the replacement and installation of punch-pin 220.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
