Description
Technical field
The utility model belongs to technical field of operation, is related to a kind of cold extrusion die, particularly a kind of automobile starting switch
The cold extrusion shaped cavity plate of shell.
Background technology
Automobile starting switch shell is one of important component of automobile starting switch；Traditional switch housing using hot forging manufacture and
Into.A switch housing as shown in Figure 1, the lateral surface tail end of switch housing has two symmetrical recessed shoulders, and then is easy to switch housing
Installation.Existing recessed shoulder is process using miller skill；In order to improve processing efficiency, people in the art, which uses, can process two at the same time
The special purpose machine tool of a recessed shoulder is processed.As market competition becomes increasingly fierce, those skilled in the art wish to further carry
High switch housing production efficiency.
The content of the invention
The utility model proposes a kind of cold extrusion shaped cavity plate of automobile starting switch shell, skill to be solved in the utility model
Art problem is how to improve switch housing production efficiency.
The technical problems to be solved of the utility model can be realized by following technical proposal：This automobile starting switch shell
Cold extrusion shaped cavity plate includes pedestal and the profiled sheeting being fixedly connected with pedestal, has the forming hole of perforation, shaping in profiled sheeting
There are two protrusions for being used to be molded recessed shoulder, protrusion extends sideways to the bottom surface of profiled sheeting on the hole wall in bottom hole portion；Two
The inner core that can be moved axially along forming hole is equipped between a protrusion；Between inner core and pedestal be oriented to connection and the bottom surface of inner core and
Spring is equipped between pedestal.
The utility model provides a kind of cold extrusion shaped cavity plate of automobile starting switch shell so that automobile starting switch shell can
It is molded using cold-extrusion technology.Due to having protrusion in cavity plate, switch housing once cold extrusion is molded just to mold recessed shoulder, changes speech
It, recessed shoulder is without following process.
Compared with prior art, making automobile starting switch shell using this cold extrusion shaped cavity plate has production efficiency more
The advantages of height, manufacture cost is lower, quality is more excellent and more environmentally friendly.

Embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in Figures 2 to 4, the cold extrusion shaped cavity plate of this automobile starting switch shell includes pedestal 1 and profiled sheeting 2, shaping
Plate 2 is fixedly connected with pedestal 1, and pedestal 1 includes bottom plate 1a and middle connecting plate 1b, and middle connecting plate 1b is located at bottom plate 1a and shaping
Between plate 2.
There is the forming hole 2a of perforation, the side wall of forming hole 2a includes arc sections 2b, forming hole 2a at the center of profiled sheeting 2
Lower part in have two relative to arc sections 2b protrude protrusion 2c, protrusion 2c be used for formed automobile starting switch shell in
Recessed shoulder 5.
There is protrusion 2c top surface 2c1 and side 2c2, the side 2c2 of protrusion 2c to extend to the bottom surface of profiled sheeting 2；Into
And the intensity of protrusion 2c is effectively improved, it is met to be molded the intensity needed for recessed shoulder and improve service life.Protrusion 2c
Top surface 2c1 be obliquely installed relative to side 2c2, arc chord angle transition is used between the side 2c2 and top surface 2c1 of protrusion 2c,
Arc chord angle transition is used between the top surface 2c1 and arc sections 2b of protrusion 2c.The structure is conducive to raising metal and is pressed through in cold-extruded
Mobility in journey, and then satisfactory recessed shoulder 5 can be molded, while the switch housing after shaping is smoothly taken off
Mould.
Titanium nitride coating is coated with the forming hole 2a hole walls of profiled sheeting 2, and then significantly increases cold extrusion shaped cavity plate
Wearability.
The inner core 3 that can be moved axially along forming hole 2a is equipped between two protrusion 2c；The top cross-sectional shape of inner core 3
Shape matches between two protrusion 2c.Connection is oriented between inner core 3 and pedestal 1 and between the bottom surface of inner core 3 and pedestal 1
Equipped with spring 4；Specifically, pilot hole is provided with middle connecting plate 1b, inner core 3, which is threaded through in pilot hole and is formed, is oriented to knot
Structure, and then it is effectively guaranteed 3 the moving stability of inner core.One end of spring 4 and the bottom surface of inner core 3 lean, spring 4 it is another
End leans with bottom plate 1a.
Automobile starting switch shell as shown in Figure 1 is made using the cold extrusion die with this molding concave die by illustrating, into
One step illustrates the beneficial effect of cold extrusion shaped cavity plate.When this cold extrusion shaped cavity plate is in the normal state, bullet of the inner core 3 in spring 4
Power effect is lower in a high position, i.e., the top surface 2c1 of inner core 3 is flushed with the top surface 2c1 of protrusion 2c substantially.Blank is put into forming hole
In 2a, the core rod of cold extrusion die convex mould is penetrated in forming hole 2a, is forced blank deformation and is forced spring 4 to compress, is i.e. inner core 3
Move downward, automobile starting switch shell as shown in Figure 1 can be molded by the pressure and stroke that control punch-pin, i.e. automobile starting is opened
Closing in shell has two recessed shoulders 5.
