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 frock are used for semicanal
Striking for formula part is repaiied processing and examined.
Background technology
As depicted in figs. 1 and 2, the type is struck inspection mould and is made up of 01# carcass I and 02# carcasses II, first as processing when using
Frock is struck respectively repaiies corresponding 01# part I and 02# parts II.After being completely processed, 01# carcass I and 02# carcasses II is assembled
Together, the correctness of part type face and outline is examined, also examines the part I machined and part II whether can phase
Match somebody with somebody.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of more rational technique processing scheme, reduces double semicanal mandrels
Formula strikes the torsion in process of inspection mould and warpage, farthest reduces mismachining tolerance, the frock is reached higher
The accuracy of manufacture.
Processing and role of inspection are repaiied because the type frock has concurrently to strike, it is therefore desirable to possess certain hardness and wearability,
Cause heat treatment step essential.Frock causes the deformation of various trend due to stress release and heat treatment in process,
Such as warpage, torsion etc., the part of frock two can not be bonded when being used cooperatively checking function, although adding work base plane can expire
Sufficient one-piece part machining function, but the position relationship between binding face and type face can not be met, coarse inspection work(can only be played
Can, limited accuracy, the required precision of new generation product can not be met.

Degree, reinstalls tool palette；
11) numerical control 3：Finishing drum face, reference holes, stays the amount of finish reaming, and draws part edge line；Take and lead processing method,
Voluntarily add some guide lines, subregion processing；Ensure Tool in Cutting track as far as possible perpendicular to frock semi-cylindrical axis, no
Made allowance, completely by digital-to-analogue requirement processing in place；Process step pitch 0.3mm, feed speed 6000mm/min, lathe rotating speed 3000
Turn/min；
12) survey：Measurement keeps a record；
13) clamp：Tear tool palette open, plug-hole freezes equating, and web surface repaiies streamline, repairs the drilling of installation tool plate institute, and sharp edge falls
It is blunt, polishing type face, repair the non-milling of numerical control everywhere, working face and the smooth streamline of non-working surface, mend and draw part edge line, finish ream numerical control system
Each hole, each part is collected, is dressed up, hand over inspection.
Beneficial effects of the present invention：This method after largely manufacturing procedure and the heat treatment step of material is removed, increases respectively
Add proof stress to discharge and eliminate the treatment process of caused deflection in process, the final deformation amount control of frock is existed
It is 1/3rd of original mismachining tolerance in the range of ± 0.05mm.
