Abstract
The utility model is suitable for a mould technical field provides a numerical control stamping die. This numerical control stamping die includes the die, terrace die and material returned board, the work piece presss from both sides tightly between die and material returned board and impresses the work piece in the die and processed the finished product through the terrace die, the die including the upper surface of placing the work piece and in the upper surface be equipped with and process finished product size corresponding and with the terrace die relatively for the through -hole of the ejection of compact, the outer wall and the upper surface mutually perpendicular of terrace die, the inner wall and the last surface vertical of through -hole, clearance between the outer wall of terrace die and the inner wall of through -hole is 1180-1120 of work piece thickness. This numerical control stamping die sets up to 1180-1120 of work piece thickness through the clearance between terrace die outer wall and through -hole inner wall, has reduced the punching press surplus greatly to reduce workpiece surface's tear -strip by a wide margin, thereby satisfy the sectional high accuracy requirement of work piece, and this numerical control stamping die simple structure, the availability factor is high, has greatly reduced the mould utility cost.
Description
Technical field
The utility model belongs to technical field of mold, particularly relates to a kind of digital stamping mould.
Background technology
The cross section quality of the stamping products that common diel is carried out punch process to material and formed is generally poor, and the quality of stamping products cross section quality also affects the attractive in appearance of its outward appearance to a certain extent.
Along with the development of society, it is more and more that stamping products uses in the production and life of people.The requirement of consumer to product is more and more higher, and they not only wish the multiple functional of product, equally also wishes that the outward appearance of product is more and more attractive in appearance.In existing stamping technology, between patrix and counterdie, generally leave certain punching press gap.Usually, the thickness of sheet material to be punched is thicker, and this punching press gap is larger, and tear-strap is more, and the euphotic belt on stamping products section is fewer, and thus the cross section quality of stamping products is poorer, thus affects the outward appearance of this stamping products.
For the stamping products that section required precision is higher, existing diel and stamping technology do not reach requirement.If it is higher to obtain cross section quality, need to utilize Digit Control Machine Tool to carry out machined to stamping products operative end surface, to obtain the stamping products of high accuracy cross section quality, but the Digit Control Machine Tool same price is expensive, and not only manufacturing cost is high, and can only single-piece work, can not realize automatic batch production, production efficiency is low, cannot meet the demand of factory's high production capacity.
Utility model content
The purpose of this utility model is to provide a kind of digital stamping mould, the not high and inefficient problem of the Product Precision being intended to solve diel processing in prior art.
The utility model realizes like this, a kind of digital stamping mould, comprise the die of place work piece, the punch be oppositely arranged with described die and the stripper for described workpiece being pressed on described die upper surface, described Workpiece clamping is between described die and described stripper and be pressed in described die by described workpiece by described punch and obtain processed finished products, described die comprises the upper surface of placing described workpiece and is provided with in described upper surface corresponding to described processed finished products size and with described punch relatively for the through hole of discharging, the outer wall of described punch is mutually vertical with described upper surface, the inwall of described through hole is vertical with described upper surface, gap between the outer wall of described punch and the inwall of described through hole is 1/180 ~ 1/120 of described thickness of workpiece.
Further, the gap between the outer wall of described punch and the inwall of described through hole is 1/150 of described thickness of workpiece.
Further, described stripper is provided with the via that for described punch pass contact described workpiece corresponding with described through hole.
Further, the aperture of described via is greater than the external diameter of described punch.
Further, the thickness of described stripper is obviously greater than the thickness of described workpiece.
The utility model relative to the technique effect of prior art is: this digital stamping mould is by being set to 1/180 ~ 1/120 of described thickness of workpiece through the gap between described punch outer wall and described through-hole wall, substantially reduce punching press surplus, significantly to reduce the tear-strap of described surface of the work, thus meet the high-precision requirement of described workpiece section, and this digital stamping mould structure is simple, service efficiency is high, significantly reduces mold use cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, be briefly described to the accompanying drawing used required in the utility model embodiment or description of the prior art below, apparently, accompanying drawing described is below only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
