Description
Technical field
The invention belongs to technology field, more particularly to a kind of nonmetallic baffle ring blanking apparatus.
Background technology
Nonmetallic baffle ring dimensions is numerous, is common component of machine.If plastic seal baffle ring is a kind of nonmetallic
Baffle ring, its effect in axis class hydraulic packing is to prevent sealing ring to be extruded mounting groove in a high voltage state, it is ensured that sealing effect
The reliability of fruit.
As illustrated in fig. 1 and 2, conventional plastic Sealing shield ring has certain thickness, and it is typically to be formed by bar car system that it, which is processed,
And for ease of installation, skewed slot is axially provided with, but thus can influence protecting effect of the plastic seal baffle ring to sealing ring.
In order to improve the sealing effect of plastic seal baffle ring, as shown in figure 3, plastic seal baffle ring is changed to knot of not slotting
Structure, the blank material of plastic seal baffle ring is modified polyimide plate.Improved plastic seal baffle ring is greatly improved to close
The anti-extrusion effect of seal.But because the blank of plastic seal baffle ring is band coating plate after improving, and the ruler of inside and outside circle
Very little tolerance and concentricity tolerance require higher, therefore can not ensure the size of product using conventional turning process method
It is required that the present invention is designed in this context.
The content of the invention
Existing turning process method can not machining blanks material be band coating plate nonmetallic baffle ring.This hair
Bright purpose is, in view of the above shortcomings of the prior art, there is provided a kind of nonmetallic baffle ring blanking apparatus.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of nonmetallic baffle ring blanking apparatus, including inner punch and the outer ram being sleeved on outside inner punch, the inner punch
With outer ram clearance fit and highly equal, the bottom of inner punch is equipped with radius and is equal in the circle of nonmetallic baffle ring internal bore radius
Cutting edge, the bottom of outer ram are equipped with the outer cutting edge of circle that radius is equal to nonmetallic baffle ring exradius, the inner cutter hole and outside
Mouth is coaxial, and the annular groove that can accommodate the nonmetallic baffle ring of finished product is equipped between the bottom of inner punch and the bottom of outer ram.
, can be to nonmetallic baffle ring by said structure through overtesting（Such as plastic seal baffle ring）Punching shaping, energy
Ensure that punching goes out qualified nonmetallic baffle ring in plate blank, efficiently solve to inside/outside diameter size precision and concentricity requirement
The processing request of high nonmetallic baffle ring.
Further, dnockout handle is further included, kidney slot is vertically provided with the outer ram, the dnockout handle passes through should
Kidney slot is simultaneously connected with inner punch.
After the completion of nonmetallic baffle ring punching, dnockout handle can be utilized to drive inner punch to move down, so that nonmetallic
Baffle ring is dropped out of annular groove.
Further, inner punch and/or the outer ram hypomere is provided with through hole.
The discharge being provided with beneficial to gas during dnockout of through hole.
Further, the vertical section of the inner punch is hollow shaft.
Hollow shaft design can reduce the cost of manufacture of the present invention.
The configuration of the present invention is simple, processing technology is simple, easy to operate, and processing efficiency is higher, suitable for various specifications size
Nonmetallic baffle ring（Such as Sealing shield ring, dustband）Processing, the processing quality of product can be effectively ensured.

Embodiment
As shown in Figures 4 to 7, the present invention includes inner punch 1 and the outer ram 2 being sleeved on outside inner punch 1, the inner punch
1 and 2 clearance fit of outer ram and highly equal, the top surface of inner punch 1 and outer ram 2 polishes（Ensureing inner cutter hole 11 and outside
Mouthfuls 21 in the same plane in the state of）, the bottom of inner punch 1 is equipped with radius and is equal in the circle of nonmetallic baffle ring internal bore radius
Cutting edge 11, the bottom of outer ram 2 are equipped with the outer cutting edge 21 of circle that radius is equal to nonmetallic baffle ring exradius, the inner cutter hole 11
It is coaxial with outer cutting edge 21, the annular that can accommodate the nonmetallic baffle ring of finished product is equipped between the bottom of inner punch 1 and the bottom of outer ram 2
Groove 4.Inner cutter hole 11 and 21 equal sharpening of outer cutting edge and in same level.Dnockout handle 3 is further included, is erected on the outer ram 2
To kidney slot 5 is provided with, the dnockout handle 3 is connected through the kidney slot 5 and with inner punch 1.The inner punch 1 and outer ram 2
Hypomere is provided with through hole 6.The vertical section of the inner punch 1 is hollow shaft.The vertical section and horizontal segment of the inner punch 1 are integrated into
