Abstract
The invention discloses a processing technology for a concave and convex mold. The technology includes the following steps: preparing blank, planing six surfaces, executing plane abrasion, clamping, taking heat treatment, form grinding, line cutting and fine trimming. The processing technology for the concave and convex mold can reasonably determine the structure, material, processing precision and surface roughness of the mould, the processing operation is convenient and the cost is reduced.
Description
Technical field
The present invention relates to mould applications, be specially a kind of male and female mold 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, Linear cut → electric spark → slow wire feeding → electric spark → bedding-in, front-end-of-line has car, brill, milling and mill respectively, back segment operation electric spark, numerical control mill and fast, slow Linear cut, grinding etc.After completing complicated curved surface and aperture operation, the depth of parallelism of face shape requires to reach 10-5 μm, and the required precision of aperture controls as 1-5 μm, to ensure the quality of mould.Be SLD high abrasion height chromium cold work tool steel at drift material used; heat treatment with application of vacuum for time main; to some mould; the mould of the undershoot in such as flange type one under three; conventional structure is thinner in platelet position wall ratio, because the impact by effect of stress often there will be the phenomenon having distortion in cutting on line process, thus causes die deformation to be scrapped; have a strong impact on the efficiency of production, also cause the waste of resource.Due to the accumulation of error of machining, make after mosaic splicing, to there is 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 carry out rectification processing, nonetheless, this segment deviation still can when mold work, light then make angle ejector rod plucking, wearing and tearing aggravation, heavy then make angle ejector rod occur killing, fractureing fault, cause that the maintenance cost of mould increases, the mold use lost of life; Therefore, it is large to there is inclined top hole deviation in prior art, Making mold and the problems and shortcomings that maintenance cost is high, service life is short.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of convex concave mould processing technology, its processing step is as follows:
(1) blank prepares: to workpiece blanking, rough forging;
(2) dig six: the perpendicularity measuring two adjacent surfaces with 90 ° of angle squares, thickness stays 0.15-0.3mm;
(3) plain grinding: polish thickness two plane and side datum level, ensures the perpendicularity of two adjacent surfaces;
(4) pincers worker: draw each hole and wire hole;
(5) heat treatment: quenching, tempering, and check hardness;
(6) plunge grinding: mill thickness two plane is to requiring;
(7) Linear cut: cutting profile is to requiring;
(8) refine: the gap uniformity controlling punch and die.
Preferably, the temperature of described quenching is 980-1020 DEG C.
Preferably, the temperature of described tempering is 130-150 DEG C.
Beneficial effect of the present invention: have structure, material, machining accuracy and the surface roughness of rationally determining mould, makes easy to process, cost reduction.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
A kind of convex concave mould processing technology, its processing step is as follows:
(1) blank prepares: to workpiece blanking, rough forging;
(2) dig six: the perpendicularity measuring two adjacent surfaces with 90 ° of angle squares, thickness stays 0.15-0.3mm;
(3) plain grinding: polish thickness two plane and side datum level, ensures the perpendicularity of two adjacent surfaces;
(4) pincers worker: draw each hole and wire hole;
(5) heat treatment: quenching, tempering, and check hardness;
(6) plunge grinding: mill thickness two plane is to requiring;
(7) Linear cut: cutting profile is to requiring;
(8) refine: the gap uniformity controlling punch and die.
In the present embodiment, blank forms cold rolling for 8-16cm round bar roll squeezer, and the temperature of quenching is 980-1020 DEG C, and the temperature of tempering is 130-150 DEG C.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
