Abstract
The invention discloses a fine stamping mould technique with a pressing plate. The fine blanking mould technique comprises the following steps that a plate is tightly pressed on a concave mould by the brute-force pressing plate, a convex mould moves downwards to stamp the plate, and a push part plate abuts against the plate at the same time; and the plate on the concave mould is stressed by unit stress close to the yield limit to enable metal at the blanking deforming area to be in a three-direction pressure stress state to form shearing separation. The convex mould is fixed to the upper portion of a fine blanking mould frame, and the concave mould is fixed to the lower portion of the fine blanking mould frame. The brute-force pressing plate, the convex mould and the concave mould are made of alloy tool steel with good hardenability and small deformation and have the beneficial effects of being stable in stress and not prone to deforming.
Description
Technical field
The invention belongs to field of machining, be specifically related to a kind of pressing plate fine blanking die technique.
Background technology
Punch die is the major process unit of punching production, and punch die structure design is very large on the impact of stamping parts quality, productivity ratio and economic benefit.Diel is exactly in Cold Press Working, material (metal or nonmetal) is processed into a kind of special process equipment of part (or semi-finished product).Therefore, understanding punch die structure, all technical of research and raising punch die, is very necessary to Stamping Die Design and development stamping technology.Classify to punch die by different features, its sorting technique mainly contains: (1) can be divided into blanking die, Drawing Die, flange die, bulging die, bending die by stamping procedure character Traditionally blanking die is used as the general name of all separation circuit moulds, comprises blanking die, perforating die, knife edge die, edger, half fine blanking die, fine blanking die and shaving die etc.
Summary of the invention
The present invention is intended to the defect overcoming prior art, provides a kind of pressing plate fine blanking die technique, has steadily stressed, on-deformable advantage.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of pressing plate fine blanking die technique, comprise the steps, plate 3 is pressed on die by a, powerful pressing plate 2, the descending stamping-out of punch 1, and push piece plate 5 is top pressing board material simultaneously; Plate on b, die is subject to the unitstress close to yield limit, under making the metal in stamping-out sex change district be in three-dimensional compressive stress state, is formed and shears separation.
Further, punch is fixed on Fine punching die frame top, and die is fixed on Fine punching die frame bottom.
Further, powerful pressing plate, punch, die adopt quenching degree good, be out of shape little alloy tool steel making.
Compared with prior art, the present invention has following beneficial effect:
The present invention selects good Sheet Metal Forming Technology, and convex-concave die holder all supports by force bearing ring, steadily stressed; Mould bases load area is large, not yielding.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the pressing plate fine blanking die device of pressing plate fine blanking die technique of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of pressing plate fine blanking die technique, comprises the steps, plate 3 is pressed on die by a, powerful pressing plate 2, the descending stamping-out of punch 1, and push piece plate 5 is top pressing board material simultaneously; Plate on b, die 4 is subject to the unitstress close to yield limit, under making the metal in stamping-out sex change district be in three-dimensional compressive stress state, is formed and shears separation.Wherein, punch is fixed on Fine punching die frame top, and die is fixed on Fine punching die frame bottom.Powerful pressing plate, punch, die adopt quenching degree good, be out of shape little alloy tool steel making.
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 amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
