Description
Technical field
The invention belongs to Technology field, particularly to a kind of nonmetal back-up ring blanking apparatus.
Background technology
Nonmetal back-up ring dimensions is numerous, is common component of machine.If plastic seal back-up ring is a kind of nonmetal back-up ring, its effect in axle class hydraulic packing is to prevent sealing ring to be extruded mounting groove in a high voltage state, it is ensured that the reliability of sealing effectiveness.
As illustrated in fig. 1 and 2, conventional plastic Sealing shield ring has certain thickness, and its processing is usually formed by bar car system, and for ease of installing, axially has skewed slot, but thus can affect the plastic seal back-up ring protected effect to sealing ring.
In order to improve the sealing effectiveness of plastic seal back-up ring, as it is shown on figure 3, plastic seal back-up ring changes into not notching construction, the blank material of plastic seal back-up ring is modified polyimide plate.Plastic seal back-up ring after improvement is greatly improved the anti-extrusion effect to sealing ring.But, because the plate that blank is band coating of plastic seal back-up ring after improving, and the dimensional tolerance of inside and outside circle and concentricity tolerance require higher, conventional turning process method therefore cannot be adopted to ensure the dimensional requirement of product, design the present invention in this context.
Summary of the invention
Existing turning process method cannot machining blanks material be the nonmetal back-up ring of plate of band coating.It is an object of the invention to, for above-mentioned the deficiencies in the prior art, it is provided that a kind of nonmetal back-up ring blanking apparatus.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is:
A kind of nonmetal back-up ring blanking apparatus, including inner punch and be enclosed within the outer ram outside inner punch, described inner punch and outer ram matched in clearance and highly equal, the bottom of inner punch is provided with the radius circular inner cutter hole equal to nonmetal back-up ring internal bore radius, the bottom of outer ram is provided with the radius circular outer cutting edge equal to nonmetal back-up ring exradius, described inner cutter hole and outer cutting edge are coaxial, are provided with, between bottom and the bottom of outer ram of inner punch, the cannelure that can hold the nonmetal back-up ring of finished product.
Through overtesting, by said structure, to a stamping-out molding of nonmetal back-up ring (such as plastic seal back-up ring), can guarantee that and make qualified nonmetal back-up ring in plate blank upper punch, efficiently solve the processing request that inside/outside diameter size precision and axiality are required high nonmetal back-up ring.
Further, also including dnockout handle, described outer ram vertically has kidney slot, described dnockout handle is connected through this kidney slot and with inner punch.
After nonmetal back-up ring punching completes, it is possible to use dnockout handle drives inner punch to move down, thus nonmetal back-up ring drops in cannelure.
Further, described inner punch and/or outer ram hypomere have through hole.
Being provided with of through hole is beneficial in dnockout process the discharge of gas.
Further, the vertical section of described inner punch is hollow axle.
Hollow shaft design can reduce the cost of manufacture of the present invention.
Present configuration is simple, and processing technique is simple, and easy to operate, working (machining) efficiency is higher, it is adaptable to the processing of the nonmetal back-up ring (such as Sealing shield ring, dust ring etc.) of all size size, can be effectively ensured the crudy of product.

Detailed description of the invention
As shown in Figures 4 to 7, the present invention includes inner punch 1 and is enclosed within the outer ram 2 outside inner punch 1, described inner punch 1 and outer ram 2 matched in clearance and highly equal, the end face of inner punch 1 and outer ram 2 polishes (when ensureing in inner cutter hole 11 and outer cutting edge 21 are in the same plane), the bottom of inner punch 1 is provided with the radius circular inner cutter hole 11 equal to nonmetal back-up ring internal bore radius, the bottom of outer ram 2 is provided with the radius circular outer cutting edge 21 equal to nonmetal back-up ring exradius, described inner cutter hole 11 and outer cutting edge 21 are coaxial, it is provided with, between bottom and the bottom of outer ram 2 of inner punch 1, the cannelure 4 that the nonmetal back-up ring of finished product can be held.Inner cutter hole 11 and the equal sharpening of outer cutting edge 21 and in same level.Also including dnockout handle 3, described outer ram 2 vertically has kidney slot 5, described dnockout handle 3 is connected through this kidney slot 5 and with inner punch 1.Described inner punch 1 and outer ram 2 hypomere have through hole 6.The vertical section of described inner punch 1 is hollow axle.Vertical section and the horizontal segment of described inner punch 1 are formed in one or are spliced.Vertical section and the horizontal segment of described outer ram 2 are formed in one or are spliced.
Size according to nonmetal back-up ring dimensions, is designed to structure three kinds different by the present invention, improves the operability of the present invention with this.If the external diameter of nonmetal back-up ring is D, structure in Fig. 4 is applicable to the nonmetal back-up ring of punch press process 5mm < D≤35mm, structure in Fig. 5 is applicable to the nonmetal back-up ring of punch press process 35mm < D≤135mm, and the structure in Fig. 6 is applicable to the nonmetal back-up ring of punch press process 135mm < D≤250mm.
As it is shown in fig. 7, the machine work principle of the present invention is as follows:
The blank 7 of nonmetal back-up ring is placed on the Vybak plate 8 of 5 millimeters thick by naturalness, then inner cutter hole 11 and the outer cutting edge 21 of the present invention are placed on blank 7 down.Use press ram 9 to apply pressure on the end face of the present invention, get final product punching simultaneously and go out cylindrical and the endoporus of nonmetal back-up ring.Driving inner punch 1 to move again through dnockout handle 3, the nonmetal back-up ring finished product that can punching be gone out unloads and falls.The hole size of nonmetal back-up ring is ensured in the process by inner cutter hole 11 size of inner punch 1, the excircle dimension of nonmetal back-up ring is ensured, simultaneously by the concentricity tolerance ensured between the inside and outside circle of nonmetal back-up ring that is slidably matched high-precision between inner punch 1 and outer ram 2 by outer cutting edge 21 size of outer ram 2.
