2mm, over all dimension: Long for 1290mm, wide for 220mm, it is 67mm high. Graph 1 before defend the measure that shell plating bumping into bridge shows a product 1 times according to the graph, we can see, this product is exterior form is not complex, but belong to high strenth armor plate however. Normally, to the punch process of spare parts of high strenth plank, can produce the problem such as spare parts twist, spring back and warp, must try to solve. Accordingly, the following item notices in wanting to establish a procedure in punch craft: 1.
Pull delay figuration to want spare parts of plank of sufficient high strength to be when punch, its appearance should be pulled entirely as far as possible delay come out, working procedure of the flange of the foreword after leaning, plastics will come true, that is to say, want to delay figuration through pulling, the plasticity that makes board makings generation sufficient is out of shape, reduce the spring back stress of oneself. But the plasticity that how can just make generation of high strenth plank sufficient is out of shape, need passes the craft complement with reasonable design to come true, before of this kind of spare parts pull those who delay muscle to design a circle normally, but to this, we used square muscle, see a picture 2 with the graph 3. Graph 2 before prevent shell plating bumping into bridge to pull delay digital-to-analogue to pursue 3 before prevent shell plating bumping into bridge to pull delay square muscle measure 2.
After undertaking CAE analysis delays figuration working procedure to do good digital-to-analogue through pulling, must want to undertake CAE is analysed, and the result that the basis analyses, decide volume of sequel of spare parts spring back, try to compensate on data next, the digital-to-analogue after using compensation regards treatment as the basis. Graph 4 with the graph 5 be the spare parts in this case pull delay compensation of working procedure spring back. Graph 4 before prevent shell plating bumping into bridge to pull delay fore-and-aft spring back to compensate 3.
Data of treatment of punching mould face pulls the mould of the punching that decorate a border before extending process of nap of working procedure hind, flange face to process data surely really, must good with debugging pull finally delay to allow, and spring back compensatory cannot have been made in order to pass CAE pull the modulus that extend number to allow according to be after the analysis. This is delayed to be being pulled finally with respect to need undertake converse build a model, next with converse the basis of treatment craft digital-to-analogue that the data that builds a model builds edge punching pattern as treatment. Graph 5 before prevent shell plating bumping into bridge to pull delay transverse spring back to compensate 4.
The analysis of digital-to-analogue of flange plastics treatment also should undertake to the treatment digital-to-analogue of flange plastics CAE analysis and spring back are compensated, regard the treatment of this line working procedure as the basis with this. If the graph is shown 6 times,the spring back of flange plastics working procedure of this spare parts is compensated. Graph 6 before the spring back that defends process of plastics of shell plating bumping into bridge is compensated 5.
Other attention problem besides afore-mentioned problems, the staff member still answers the characteristic according to the spare parts, the material of component of affirmatory good job is qualitative, decide what section needs to pass special heat treatment. Although computer technology is very at present advanced,the mould is made, but the external condition when using the computer to undertake CAE is analysed and the real environment when the mould works cannot be identical, the actual condition that the basis when needing to be debugged in production debugs undertakes be compensatinged again. Accordingly, must amend way considering what adopt when the mould is made, main note is as follows: 1.
Pull delay kind of mould to extend kind of pattern to pulling, if the mould is used,cast a structure, bubble model when full mold process model the face should leave surplus more, so that be rectified and reform later. If the mould is used,set cake form, want to have 2 groups expect at least. 2.
Long edge, punching kind the Xiu Chong before the mould delays nap of working procedure hind, flange to pulling kind mould, of the mould model face data must good with debugging pull finally delay to allow. 3.
Flange plastics kind mould to flange plastics kind mould, because mould job component is used more,set cake form, because this wants equipment at least,two groups expect. 4.
Experience accumulates detailed notes to adjust data every time, accumulate the relevant experience of punch of this kind of material. Epilogue above content introduced a car to enclothe in the punch technology design of high strenth plank and mould make a note, use these notes adequately article model -- before in the development that prevents mould of shell plating bumping into bridge, received very successful application. Satisfied a client to shorten not only the manufacturing cycle, requirement that improves product quality, the pattern that also develops high strenth board for my factory at the same time accumulated valuable experience, make the level of integral punch technology of my factory rose again a new chance to extricateoneself from an awkward position.
