Description
Technical field
The present invention relates to a kind of diel, specifically, relate to a kind of drift and process for stamping thereof of diel.
Background technology
Energy shortage and environmental pollution are seriously the significant problems existed now, pursue low energy consumption, trend that the guarantee of environmental protection and personal safety has become technical research and development.Along with the development of materials industry technology, increasing lightweight, highdensity material will substitute thick and heavy, low intensive material in the past, to save material resources and to reduce the energy needed for running, and can ensure personal safety.
At present, in Sheet Metal Forming Technology process, select high-strength plate must improve blanking pressure and meet the requirement of processing, the requirement of the pressing equipment needed for Sheet Metal Forming Technology, diel, punch elements is improved along with the lifting of blanking pressure.Therefore, although achieve the raw material business of product the loss that low energy consumption adds material and the energy in stamped process.Simple mould as shown in Figure 1, the performance of its inner member all needs to strengthen.
Drift realizes one of cold stamping shaped important punch elements, nowadays, drift has become the standardization spare and accessory parts of punching press industry, is applied among each punching press field, if the brands such as DAYTON, FIBRO, MISUMI and PUNCH are all enterprises representative in the sector.When drift uses, drift directly contacts with material to be punched, makes material deforms to be punched, cuts material.The stamping-out pattern of conventional drift is the shape in the hole according to expection, and profiling makes drift, and the end profile of drift is the shape of final punching, is coordinated, complete blanking process instantaneously by drift with the shearing of die.As shown in Figures 2 and 3, during standard punch work, namely during stamping-out, need certain blanking pressure, wherein, f is demoulding power, and unit is: N.The computing formula of blanking pressure is as follows:
F＝K*L*t*τ
In formula, F is blanking pressure, unit: N; K is safety coefficient, generally gets K=1.3; L is stamping-out girth, unit: mm, when punching is circular, and L=π * d; T is material thickness, unit: mm; τ is material shearing strength, and unit is MPa.
As can be seen from the above equation, the higher required blanking pressure of the strength of materials is larger.
From the above, existing stamping-out mode determines the size of blanking pressure, if select higher blanking pressure to process, the higher pressing equipment of performance requirement, diel and Stamping Die Standard-parts is then needed to meet production accordingly, affect and limit the development of industry, improve mould production cost and cycle, also waste resource and the energy.
Authorization Notice No. is the drift that the Chinese utility model patent of CN202591370U discloses a kind of diel, and specifically disclose following technical characteristic: comprise drift body, described drift body has processing tip and handle part, seamlessly transit between processing tip and handle part, handle part also offers the draw-in groove being convenient to assemble.The utility model is applied in diel, and assembling is simple, can bear larger pressure, not fragile, long service life.Similarly, blanking pressure is larger, the pressing equipment supporting with the utility model patent and the performance requirement of diel also higher, the production cost and period of mould is high, there is waste resource and the problem of the energy.
Summary of the invention
