The integral stamping die has the beneficial effects of achieving one-time stamping molding and being good in repeatability and high in machining speed; the problem about batch machining of the male die units is solved, and meanwhile the problems that the consistency of the spherical radii of male dies is poor, the surface roughness of the male dies is insufficient, and repair is hard when bad points occur during machining are solved; and a new scheme is provided for machining of the optical reflection checkered mirror.
Description
Technical field
The invention belongs to and expand with optics reflector net stricture of vagina mirror manufacture field.
Background technology
Optical reflection reticulate pattern mirror plays the effect expanded in reflective optical system.Existing optical reflection reticulate pattern mirror punch die processing scheme is in piece blank, use the punch array required for diamond mill Milling Process, forming principle according to Milling Process, it is difficult to when processing curve obtain relatively low surface roughness, and in the course of processing, cutter there will be abrasion, causes each unit spherical radius in punch array difference occur.And in the large area array course of processing, occur that the process of cutter is changed in midway, also can introduce the error to cutter centering.So existing scheme exists processing charges height, process-cycle length, punch spherical radius concordance is poor, convex mould surface roughness is of a relatively high and processing is difficult to the defect repaired when there is bad point.
Summary of the invention
The present invention overcomes the deficiency of existing processing scheme, it is provided that a kind of new fabrication scheme can reduce the dependence to high cost equipment in the optical reflection reticulate pattern mirror monoblock type punch die course of processing, uses conventional batch processing method to obtain high-quality punch die unit.
The technical solution used in the present invention is: a kind of monoblock type punch die for optical reflection reticulate pattern mirror die process; including punch die substrate and punch member; it is characterized in that punch die substrate and punch member are independently processed; again punch member array is connected on punch die substrate after machining, forms the monoblock type punch die for processing optical reflection reticulate pattern mirror.Described punch die substrate, it is ensured that punch die integral face type, its face type is determined according to the face type of optical reflection reticulate pattern mirror to be processed, it is possible to be plane or sphere, uses common die steel, adopts general lathe equipments to its machine-shaping.Described punch member, be adopt metal ball be blank, the quadrangular that two ends are standardized high quality sphere formed through processing, its course of processing is a number of metal ball solid matter is positioned over a surrounding with in rib, square position that flatness of trying to get to the heart of a matter is fabulous, fixture low-temperature metal is adopted to be fixed among square position by metal ball, with cutting equipment, metal ball goes out first plane by the dimensioned designed；After completing, metal ball is taken off from square position, be again installed on square position after overturning 180 °, carry out the processing of the plane relative with first plane；The metal ball being processed into " cheese " is taken off from square position, changes the square position of a reduced size, metal ball is supported with sphere, is installed on square position, carry out the processing of the 3rd；Again metal ball is taken off from square position, be installed on square position after overturning 180 °, carry out the processing of fourth face；So far, punch member machines, and punch member is close-packed arrays on substrate, forms press work face.
Compared with prior art; the invention has the beneficial effects as follows: determined punch die integral face type by punch die substrate; punch member close-packed arrays on substrate forms press work face; have one time punching molded; reproducible; the advantage that process velocity is fast, solves the mass processing problems of punch member, also solves the problem that punch spherical radius concordance is poor, convex mould surface roughness not enough, processing is difficult to repair when there is bad point simultaneously.

Detailed description of the invention
Owing to the working portion of whole punch die is to be formed by punch member solid matter, so what first have to solution is exactly the machine-shaping of punch member.As it is shown in figure 1, indicate that the removal process of the punch member processing of the present invention, even if metal ball becomes quadrangular, what the course of processing mainly needed solution is the reliable clamping to metal ball and batch machining.The present invention adopts fixture low-temperature metal to realize fixing metal ball.Fixture low-temperature metal is a kind of reusable cold melt alloy (fusing point is 70 ° of C), is usually used in supporting thin-wall part processing and part clamping.This alloy will not shrink when solidification, has slight " expansion " on the contrary, thus being closely clamped on part.With hot water, it is melted after completion of processing, do not have any residual.
It is designed with the mill frock of two kinds of models, uses fixture low-temperature metal by clamping after metal ball close-packed arrays on the supporting plane of mill.Then spark erosion equipment is used, it is achieved the processing to metal ball.The concrete structure of mill frock is as in figure 2 it is shown, frock is made up of frame 1 and base plate 2.Frock adopts the purpose of split-type structural to have two, and first can make the Internal periphery corner of frame 1 be processed into right angle, and second can make bottom plate support plane adopt grinding method processing, it is ensured that flatness and the depth of parallelism.
As it is shown on figure 3, be arranged closely in the mill frock of model 1 by the metal ball screened, fixture low-temperature metal is used they to be clamped.Use Wire EDM equipment that metal ball carries out the processing in first face, the course of processing notes control cutting zone temperature, it is prevented that temperature is too high causes that fixture low-temperature metal melts.
After first completion of processing, state is as shown in Figure 4, with hot water, tool low-temperature metal is melted, take off metal ball and they are cleaned out, by they planes holder plane towards mill frock after drying, again carry out clamping, as it is shown in figure 5, note not allowing impurity and fixture low-temperature metal enter metal ball plane and holder interplanar, machining accuracy otherwise can be affected.
Repeat the course of processing of first, complete the processing of the second plane (parallel with first and relative centre of sphere symmetry), as shown in Figure 6.Again metal ball being taken off and clean out, then their plane is perpendicular to the holder plane of mill frock, after solid matter, clamping is in the mill frock of model 2, as shown in Figure 7.Repeat the above course of processing and process remaining two planes, as shown in Fig. 8, Fig. 9, Figure 10.
So far, the processing of punch member is complete, it is thus achieved that a collection of four prisms cylinder as shown in Figure 1.By the sphere of punch member upwards, it is arranged closely on punch die substrate, as shown in figure 11.Then the method adopting fixture low-temperature metal or welding, is connected in all of punch member on punch die substrate.Punch die finally carries out destressing process and final cleaning work.So far, punch die machines.
