Description
Technical field
The processing of inspection mould is struck the present invention relates to a kind of double semicanal mandrel types and control deformation method, such tooling are used for semicanal
Processing and inspection are repaired in striking for formula part.
Background technique
As depicted in figs. 1 and 2, the type is struck inspection mould and is made of 01# carcass I and 02# carcass II, first as processing when using
Tooling is struck respectively repairs corresponding 01# part I and 02# part II.After the processing is completed, 01# carcass I and 02# carcass II is assembled
Together, whether the correctness for examining part type face and outer profile, also examine the part I completed the process and part II can phase
Match.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of more reasonable technique processing schemes, reduce double semicanal mandrels
Formula strikes the torsion and warpage of inspection mould in process, reduces mismachining tolerance to the greatest extent, the tooling is enable to reach higher
The accuracy of manufacture.
Processing and role of inspection are repaired since the type tooling has both to strike, it is therefore desirable to have certain hardness and wearability,
Cause heat treatment procedure essential.Tooling leads to the deformation of various trend due to stress release and heat treatment in process,
Such as warpage, torsion etc. can not be bonded, although adding work bottom plane can expire when making two component of tooling with the use of checking function
Sufficient one-piece part machining function, but the positional relationship being unable to satisfy between binding face and type face can only play coarse inspection function
Can, limited accuracy is unable to satisfy the required precision of new generation product.
Technical solution of the present invention:
A kind of double semicanal mandrel types strike processing and the control deformation method of inspection mould, and steps are as follows:
1) blanking: pressing woollen table illustrated dimension and trade mark blanking, and when blanking takes Water Cutting by tooling outer profile blanking, with
Evade gas flame cuttiug and causes material temperature distortion, the equal allowance 10mm of tooling outer profile machined surface；
2) it digs: needing to dig thick two faces to size by processing, stay machining allowance 5-6mm by tooling actual (real) thickness；
3) grind: thick two faces of mill are parallel, guarantee flatness；
4) it clamps: installing tool palette, bolt installation site avoidance type face and each hole additional in tooling bottom surface, take bolt fastening
Connection；
5) numerical control 1: roughing type face, uniform allowance are subsequent handling benchmark aperture；Roughing type face, takes contour
Layer processing method is dropped, selects small diameter milling knife layering processing to reduce cutting force and deflection, chipping allowance 3- is uniformly stayed in processing
0.2mm, feed speed 6000mm/min, 1500 turns/min of lathe revolving speed drop in 4mm, every layer of Z value；
6) clamp: removal tool plate is smoothed after discharging stress, guarantees soffit plane degree；
7) hot: to quench and be tempered 35-39HRC；
8) it clamps: being smoothed after stress release to be heated, grind flat and tool palette and binding face is installed, guarantee installation fitting facial plane
Degree, reinstalls tool palette；
9) numerical control 2: semifinishing type face, uniform allowance 0.5-0.6mm；Using method identical with step 5)；
10) clamp: removal tool plate discharges stress, and smoothing grinds flat and tool palette and installs binding face, guarantees fitting facial plane
Degree, reinstalls tool palette；
11) numerical control 3: finishing drum face, reference holes stay the amount of finish reaming, and draw part edge line；It takes and leads processing method,
Voluntarily add several guide lines, subregion processing；Guarantee Tool in Cutting track is as far as possible perpendicular to tooling semi-cylindrical axis, no
Made allowance, completely in place by digital-to-analogue requirement processing；Process step pitch 0.3mm, feed speed 6000mm/min, lathe revolving speed 3000
Turn/min；
12) survey: measurement keeps a record；
13) it clamps: tearing tool palette open, plug-hole freezes equating, and web surface repairs streamline, repairs the drilling of installation tool plate institute, and sharp edge falls
Blunt, polishing type face is repaired numerical control and is not milled everywhere, working face and the smooth streamline of non-working surface, mends and draws part edge line, finish reams several controls
Each hole collects each part, dresses up, and hands over inspection.
Beneficial effects of the present invention: this method after the largely manufacturing procedure of removal material and heat treatment procedure, increases respectively
Add proof stress to discharge and eliminate the treatment process of the deflection generated in process, the final deformation amount control of tooling is existed
It is the one third of original mismachining tolerance within the scope of ± 0.05mm.
