Abstract
The utility model is related to a kind of simple necking frock, by two sets of frocks worked in coordination, and solves during current necking and the phenomenons, the problems such as causing part rejection such as heap side, crackle, pressure amount be uneven easily occurs.The curved frock and crimping fixture used including working in coordination, curved frock includes annular body, annular body bottom is the taper work face of opening flare, cone angle scope is 50 70 °, crimping fixture includes ring-type tool assembly, annular arc groove is provided with ring-type tool assembly lower surface, circular arc slot cross-section is formed by two sections of different circular sliding slopes of radius, distal end arc radius is more than the radius close to center circular arc.Part bending face pressure is bent to certain angle by the utility model using curved frock, using crimping fixture by the face pressure of bending into arc surface, it can so ensure that pressure is uniformly acted on whole arc surface, reduce because heap side caused by local pressure, pressure amount is uneven the problems such as, product quality can be effectively ensured.
Description
Technical field：
The utility model is related to a kind of simple necking frock.
Background technology：
End face necking technology has been widely used for the connection of spherical hinge at present, and this is consistent, reliable, but to pressure
The requirement of dress process is higher, the phenomenons such as heap side, crackle, pressure amount be uneven easily occurs, causes part rejection.
The content of the invention：
The utility model by two sets of frocks worked in coordination, solve during current necking easily occur heap side, crackle,
The phenomenon, the problems such as causing part rejection such as pressure amount is uneven.
The utility model is realized by following technical scheme：
A kind of simple necking frock, including the work in coordination curved frock used and crimping fixture, curved frock include ring
Shape body, annular body bottom is the taper work face of opening flare, and cone angle scope is 50-70 °, and crimping fixture includes ring-type work
Fill and be provided with annular arc groove on body, ring-type tool assembly lower surface, circular arc slot cross-section is formed by two sections of different circular sliding slopes of radius,
Distal end arc radius is more than the radius close to center circular arc.
Part bending face pressure is bent to certain angle by the utility model using curved frock, using crimping fixture by bending
Face pressure into arc surface, can so ensure that pressure is uniformly acted on whole arc surface, reduce caused by local pressure
The problems such as heap side, uneven pressure amount, product quality can be effectively ensured
Brief description of the drawings：
Fig. 1 is the curved tool structure schematic diagram of the utility model；
Fig. 2 is the utility model crimping fixture structural representation；
Fig. 3 is the non-crimp schematic diagram of part to be processed；
Fig. 4 is schematic diagram after part to be processed crimp；
Fig. 5 is schematic diagram after part to be processed crimp, crimping.
Embodiment
As Figure 1-5, the utility model includes curved frock and crimping fixture, by part bending face pressure to certain angle
After carry out crimping, frock, using overall higher hardness material manufacture, is that can complete operation using forcing press.
Curved frock, including annular body 2, annular body bottom are the taper work face 1 of opening flare, and cone angle scope is
50-70°。
Annular arc groove 1, arc groove are provided with crimping fixture, including ring-type tool assembly 2 ', the lower surface of ring-type tool assembly 2 '
Section is formed by two sections of different circular sliding slopes of radius, and distal end arc radius is more than the radius close to center circular arc.
During work, curved frock is attached on forcing press, first with curved frock by part bending face pressure to certain angle, this
When, part highest spot diameter is less than crimping fixture arc groove apex diameter, removes curved frock, changes and part is entered by crimping fixture
Row crimping.
