Abstract
The invention discloses a die machining process. The process includes the steps of preparation of a blank, planing of six sides, plane grinding, drilling, heat treatment, wire-electrode cutting and finishing. The die machining process has the advantages that the structure, material, machining precision and surface roughness of a die are reasonably determined, machining is facilitated, and cost is lowered.
Description
Technical field
The present invention relates to a kind of mould processing technology.
Background technology
Existing mold production process is generally as follows: car → milling mark → numerical control marking → brill → heat treatment → corase grind → slow wire feeding, line cutting → electric spark → slow wire feeding → electric spark → bedding-in, leading portion operation has respectively car, brill, milling and mill, back segment operation electric spark, numerical control mill and fast, slow line cutting, grinding etc.The accumulation of error due to machining, make after mosaic splicing, to have segment deviation by the inclined top hole of each section of independent processing, in order to make up the segment deviation of inclined top hole, also need repeatedly to correct processing, nonetheless, this segment deviation still can be when mold work, gently make angle ejector rod plucking, wearing and tearing aggravations, heavy make angle ejector rod occur killing, fractureing fault, cause the maintenance cost of mould to increase, the shortening in service life of mould; Therefore, prior art exists inclined top hole deviation large, the problems and shortcomings that mould manufacture and maintenance cost are high, service life is short.
Summary of the invention
Object of the present invention, in order to solve above-mentioned problems of the prior art, provides a kind of mould processing technology exactly.
In order to achieve the above object, the present invention by the following technical solutions: a kind of mould processing technology, its processing step is as follows:
(1) blank is prepared: to workpiece blanking, rough forging;
(2) plane is six: guarantee the perpendicularity of two adjacent surfaces, thickness is reserved 0.3-0.4mm;
(3) plain grinding: polish thickness two planes and side datum level, measure the perpendicularity of two adjacent surfaces with 90 ° of angle squares;
(4) boring: adopt spark hardening technology to hole to mould;
(5) heat treatment: quenching, tempering, and check hardness;
(6) line cutting: cutting profile is to requiring;
(7) refine: the gap of controlling punch and die is even, the polishing that repairs a die by hand, obtains mould.
Preferably, described blank is that 10-25cm round bar is formed with roll squeezer is cold rolling.
Preferably, the temperature of described quenching is 1030-1070 ℃.
Preferably, the temperature of described tempering is 160-200 ℃.
Preferably, the size needing is set on wire cutting machine computer.
Beneficial effect of the present invention: the present invention can rationally determine structure, material, machining accuracy and the surface roughness of mould, makes easy to process, cost.
The specific embodiment
Embodiment: be first by the cold rolling blank of making of roll squeezer for 10-25cm round bar, then with 90 ° of angle squares, measure the perpendicularity of two adjacent surfaces, thickness stays 0.3-0.4mm, then polish thickness two planes and side datum level, with 90 ° of angle squares, measuring the perpendicularity of two adjacent surfaces, then boring, in temperature, be 1030-1070 ℃ and carry out Quenching Treatment, after Quenching Treatment is complete, in temperature, be 160-200 ℃ and carry out temper, after temper is complete, check blank hardness, then grind the thickness of two planes and the requirement that cutting blank shape arrives client, the gap of finally controlling punch and die is even.
Wherein, adopt wire cutting machine carrying out line when cutting, as long as by the size input computer of need processing, after Mould Machining completes, the craft polishing that repairs a die, guarantees die quality.
A kind of mould processing technology of the present invention, the present invention can rationally determine mould structure, material, add
Work precision and surface roughness, make easy to process, cost.
Finally it should be noted that: the foregoing is only explanation embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; within the spirit and principles in the present invention all; any modification of doing, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
