Description
Technical field
The utility model relates to a kind of mold and punching head, specially a kind of three-level hole flanging punch.
Background technique
Hole flanging, as by bore edges translate into erect side, it is different from punching, punching be by waste material along closed outline from
A kind of stamping procedure separated on material or process part processing, obtains the hole of needs on material or process part processing, and hole flanging is along inner hole week
Enclose a kind of stamping procedure that material is translated into edge-on flange.Formed punch, the metal parts in stamping die in machine tool, is called
Stick, red needle or punching pin are rushed, progress continuous stamping punching press in stamping die is mounted in and thrusts operation, send out machined material
It is estranged from or plastic deformation, thus finished product or semi-finished product required for obtaining.
A kind of three-level hole flanging punch is now provided, is designed using spherical cambered surface, waste material is not easy to be sticked to formed punch, and equipment can frequently make
With the process for the clear away waste that avoids the need for stopping meets the requirement of productive temp, high production efficiency may be implemented simultaneously
Gradually punching press reduces damage of product rate, improves production efficiency.
Utility model content
The purpose of this utility model is to provide a kind of three-level hole flanging punchs, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions：A kind of three-level hole flanging punch, including the first order
Formed punch, second level formed punch, third level formed punch and connection top, the first order formed punch, second level formed punch, third level formed punch and
Connection top is fixedly connected sequentially from bottom to top and is integrally formed part, so first order formed punch is the correcting formed punch of taper, and the
The bottom top of level-one formed punch is designed using spherical cambered surface, the first order formed punch, second level formed punch, third level formed punch and connection top
The outer diameter of head successively increases, and first order formed punch and second level formed punch junction are designed using inclined surface, the third level formed punch
It is designed with second level formed punch using curved surface, the connection top forms ladder with third level formed punch junction.
Further, the first order formed punch, second level formed punch, third level formed punch and the central axes of connection top are located at
On same straight line.
Further, the outer surface of the first order formed punch, second level formed punch and third level formed punch is coated with tungsten carbide painting
Layer.
Further, the integral piece that the first order formed punch, second level formed punch, third level formed punch and connection top are constituted
It is made of SKD11, SKH-51 or ASP-23 steel.
Further, the length of the first order formed punch is 0.6cm, and the length of the second level formed punch is 2cm, described
The length of third level formed punch is 4.3cm.
Further, the control cabinet is linked together with water tank.
Compared with prior art, the utility model has the beneficial effects that：This kind of three-level hole flanging punch, is set using spherical cambered surface
Meter, waste material is not easy to be sticked to formed punch, and equipment can be used frequently, and the process for the clear away waste that avoids the need for stopping meets production
The requirement of beat, high production efficiency, while gradually punching press may be implemented, reduce damage of product rate, improves production efficiency.
Detailed description of the invention
Fig. 1 is the utility model overall structure effect picture；
In figure：1, first order formed punch, 2, second level formed punch, 3, third level formed punch, 4, connection top, 5, inclined surface, 6, song
Cambered surface.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of three-level hole flanging punch, including first order formed punch
1, second level formed punch 2, third level formed punch 3 and connection top 4, the first order formed punch 1, second level formed punch 2, third level formed punch
3 are fixedly connected sequentially from bottom to top with connection top 4 and are integrally formed part, so first order formed punch 1 is the correcting formed punch of taper,
And the bottom top of first order formed punch 1 is designed using spherical cambered surface, the first order formed punch 1, second level formed punch 2, third level formed punch 3
It is successively increased with the outer diameter of connection top 4, and first order formed punch 1 and 2 junction of second level formed punch are designed using inclined surface 5, institute
It states third level formed punch 3 and second level formed punch 2 to design using curved surface 6, the connection top 4 and 3 junction shape of third level formed punch
