Abstract
The invention discloses a step type punch hollow thin plate stamping die structure. The step type punch hollow thin plate stamping die structure comprises an upper die and a lower die. The upper die is provided with standard punches and low hollow punches. Stamping die discharging holes are formed in the lower die. The standard punches are provided with hollow punches and non-hollow punches. The low hollow punches are also provided with hollow punches and non-hollow punches. The standard punches and the low hollow punches are evenly distributed on the upper die in a balanced mode at random. During stamping, the standard punches make plate contact with a thin plate firstly for stamping, and after stamping, the low hollow punches immediately make plate contact with the thin plate for stamping, the stamping is quite stable and balanced, the stamping force is saved, a large number of defects of bruising, surface damage, surface abnormality, insufficient surface attaching force and the like caused after stamping are avoided and reduced, and the stamping yield and the stamping economic benefits are greatly increased.
Description
Technical field
The present invention relates to diel field, be specifically related to a kind of staged drift hollow out sheet stamping die structure.
Background technology
In existing punch die manufacturing technology, thin plate punching is completed by common flat plate mold, the stamping-out cutting of article to be punched can be divided into the image of numerous abnormity, and the edge of these figures is exactly stamping-out line of cut, when stamping-out line of cut shape is more complicated, number is more, or girth longer time, punching press is easily steady, produces deviation, stamping pressure loss is comparatively large, often needs larger lathe to go punching press.And its product quality can not get management and control, and disqualification rate is more, after punching press, light sheet products often occurs that product weighs wounded, damages, the bad phenomenon such as surface abnormalities.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of staged drift hollow out sheet stamping die structure is provided, when the present invention carries out punching press, part is conventional punch, first with sheet contacts punching press, conventional punch punching press just completes, remainder drift is for engraving low drift, then two times punch is carried out with sheet contacts, ram ratio is balanced, saving stamping press comparatively steadily, the defect such as to weigh, damaged surfaces, surface abnormalities, surface adhesion force are not enough after avoiding and decrease a large amount of punch dies wounded, significantly improve punching press yields and punching press economic benefit.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of staged drift hollow out sheet stamping die structure, comprise upper die and lower die, described patrix is provided with standard punch and engraves low drift, described counterdie is provided with punch die material-dropping hole, described standard punch is provided with hollow out drift and non-hollow out drift, described hollow out drift is provided with hollow out cell body, described standard punch and engrave low drift in the distribution of patrix random uniform balance.
Further, engrave low drift described in and be also provided with hollow out drift and non-hollow out drift.
Further, it is high that described standard punch ratio engraves low drift, and difference in height is a gauge of sheet, and difference is 0.5-1.6 mm.
Further, the hollow out cell body hollow out degree of depth that described hollow out drift is arranged is 0.15-1.5mm.
The invention has the beneficial effects as follows:
When the present invention carries out punching press, part is conventional punch, first with sheet contacts punching press, conventional punch punching press just completes, remainder drift, for engraving low drift, then carries out two times punch with sheet contacts, and ram ratio is balanced, saving stamping press comparatively steadily, the defect such as to weigh, damaged surfaces, surface abnormalities, surface adhesion force are not enough after avoiding and decrease a large amount of punch dies wounded, significantly improve punching press yields and punching press economic benefit.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, and form a application's part, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is overall structure schematic diagram of the present invention.
Number in the figure illustrates: 1, patrix, 2, counterdie, 3, engrave low drift, 4, standard punch, 5, hollow out drift, 6, non-hollow out drift, 7, hollow out cell body, 8, punch die material-dropping hole.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
With reference to shown in Fig. 1, a kind of staged drift hollow out sheet stamping die structure, comprise patrix 1 and counterdie 2, described patrix 1 is provided with standard punch 4 and engraves low drift 3, described counterdie 2 is provided with punch die material-dropping hole 8, described standard punch 4 is provided with hollow out drift 5 and non-hollow out drift 6, and described hollow out drift 5 is provided with hollow out cell body 7, described standard punch 4 and engrave low drift 3 in the random uniform balance distribution of patrix 1.
Further, engrave low drift 3 described in and be also provided with hollow out drift 5 and non-hollow out drift 6.
Further, described standard punch 4 is higher than engraving low drift 3, and difference in height is a gauge of sheet, and difference is 0.5-1.6 mm.
Further, the hollow out cell body 7 hollow out degree of depth that described hollow out drift 5 is arranged is 0.15-1.5mm.
The operation principle of the present embodiment is as follows:
When making patrix of the present invention, all drifts are unified is set to standard punch 4, by being uniformly distributed, spaced apart, take into account the principle of balance, the wherein standard punch 4 of nearly half quantity is engraved low one-tenth and engraves low drift 3, engraving the low degree of depth is a gauge of sheet, flexible modulation is carried out according to concrete gauge of sheet difference, the hollow out degree of depth is generally between 0.5-1.6 mm, again by being uniformly distributed, spaced apart, take into account the principle of balance, again wherein remaining nearly half quantity standard punch 4 and engrave and low drift 3 carries out hollow out add groove, the degree of depth of hollow out is between 0.15-1.5mm, counterdie of the present invention is identical with the structure of common diel, when punching press, standard punch first contacts punching press with sheet panel top, punching press just completes, engrave low drift and namely contact punching press with sheet panel top immediately, ram ratio is comparatively steadily balanced, save stamping press, weigh wounded after avoiding and decrease a large amount of punch dies, damaged surfaces, surface abnormalities, the defects such as surface adhesion force is not enough, significantly improve punching press yields and punching press economic benefit.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
