Description
Technical field
The invention belongs to expand to use optics reflector net line mirror manufacture field.
Background technology
Optical reflection reticulate pattern mirror plays a part of expanding in reflective optical system.Existing optical reflection reticulate pattern Jing Chong
Mould processing scheme is in piece blank, using the punch-pin array required for diamond mill Milling Process, according to Milling Process
Forming principle, be difficult to obtain relatively low surface roughness in processing curve, and in process, mill occurs in cutter
Damage, causes each unit spherical radius in punch-pin array difference occur.And in large area array process, there is midway
The process of cutter is changed, can also introduce the error to knife centering.So processing charges height, process-cycle in existing scheme be present
Length, punch-pin spherical radius uniformity is poor, convex mould surface roughness is of a relatively high and the defects of being difficult to repair during bad point occurs in processing.
The content of the invention
The present invention overcomes the shortcomings of existing processing scheme, there is provided a kind of new fabrication scheme is overall in optical reflection reticulate pattern mirror
The dependence to high capital equipment can be reduced in formula punch die process, rushing for high quality is obtained using conventional batch processing method
Form unit.
The technical solution adopted by the present invention is：A kind of monoblock type punch die for optical reflection reticulate pattern mirror die process, bag
Include punch die substrate and punch member, it is characterised in that punch die substrate is independently processed with punch member, after machining
Punch member array is connected on punch die substrate again, forms the monoblock type punch die for processing optical reflection reticulate pattern mirror.It is described
Punch die substrate, ensure punch die integral face type, its face type is flat depending on the face type of optical reflection reticulate pattern mirror to be processed
Face or sphere, using common die steel, using general lathe equipments to its machine-shaping.Described punch member, it is to use
Metal ball is blank, and the both ends formed by processing are the quadrangular of standardized high quality sphere, and its process is will be certain
The metal ball solid matter of quantity be positioned over a surrounding with rib, in square position that flatness of trying to get to the heart of a matter is fabulous, using fixture low temperature gold
Among metal ball is fixed on square position by category, with cutting equipment, go out first plane by designed dimensioned in metal ball；
After the completion of, metal ball is removed from square position, is loaded again on square position after 180 ° of upset, is carried out relative with first plane
Plane processing；The metal ball for being processed into " cheese " is removed from square position, the square position of a reduced size is changed, by metal
Ball is supported with sphere, is loaded on square position, is carried out the processing in the 3rd face；Metal ball is removed from square position again, overturn
It is loaded after 180 ° on square position, carries out the processing of fourth face；So far, punch member machines, and punch member is on substrate
Close-packed arrays, form press work face.
Compared with prior art, the beneficial effects of the invention are as follows：Punch die integral face type, punch member are determined by punch die substrate
Close-packed arrays form press work face on substrate, have one time punching molded, reproducible, the advantages of process velocity is fast, solution
Determine the mass processing problems of punch member, while also solved that punch-pin spherical radius uniformity is poor, convex mould surface roughness
There is the problem of being difficult to repair during bad point in deficiency, processing.

Embodiment
Because the working portion of whole punch die is formed by punch member solid matter, so first have to solve is exactly punch-pin list
The machine-shaping of member.As shown in figure 1, it is the removal process for representing the punch member processing of the present invention, even if metal ball turns into four
Prism, what process mainly needed to solve is the reliable clamping and batch machining to metal ball.The present invention uses fixture low temperature
Metal realizes the fixation to metal ball.Fixture low-temperature metal is a kind of reusable cold melt alloy（Fusing point is 70 °
C）, it is usually used in supporting thin-wall part processing and part clamping.The alloy will not shrink in solidification, there is slight " expansion " on the contrary,
So as to closely be clamped on part.It is melted with hot water after completion of processing, does not have any residual.
Design employs the mill frock of two kinds of models, and clamping after metal ball close-packed arrays is existed using fixture low-temperature metal
On the supporting plane of mill.Then spark erosion equipment is used, realizes the processing to metal ball.The concrete structure of mill frock
As shown in Fig. 2 frock is made up of frame 1 and bottom plate 2.Frock has two using the purpose of split-type structural, and first can make frame 1
The processing of Internal periphery corner it is at a right angle, second can be such that bottom plate support plane is processed using grinding method, guarantee flatness and the depth of parallelism.
As shown in figure 3, the metal ball screened is arranged closely in the mill frock of model 1, fixture low temperature gold is used
Category clamps them.The processing in first face is carried out to metal ball using Wire EDM equipment, pays attention to control in process
Cutting zone temperature processed, prevent temperature is too high from causing fixture low-temperature metal to melt.
State after first face completion of processing removes metal ball and will as shown in figure 4, melted fixture low-temperature metal with hot water
They are cleaned out, and the support plane after drying by their planes towards mill frock, carry out clamping again, as shown in figure 5, paying attention to
It not allow impurity and fixture low-temperature metal to enter metal ball plane and support interplanar, otherwise can influence machining accuracy.
The process in the first face is repeated, completes the second plane（Parallel with the first face and relative centre of sphere is symmetrical）Processing,
As shown in Figure 6.Metal ball is removed again and cleaned out, then the support plane by their plane perpendicular to mill frock, close
Clamping is in the mill frock of model 2 after row, as shown in Figure 7.Repeat above process and process remaining two planes, such as scheme
8th, shown in Fig. 9, Figure 10.
So far, the processing to punch member has been completed, and obtains a collection of four prisms cylinder as shown in Figure 1.By punch-pin list
The sphere of member is upward, is arranged closely on punch die substrate, as shown in figure 11.Then using fixture low-temperature metal or the side of welding
Method, all punch members are connected on punch die substrate.Destressing processing and final cleaning work are finally carried out to punch die.Extremely
This, punch die machines.
