凸模

In the hydraulic counter pressure drawing,with a blank being pushed to a punch surface formed by higher fluid pressure,a good die fittingness of shells and a high accuracy of its inner diameter can be obtained.

充液拉深成形中，由于高压液体紧紧将毛坯贴向凸模表面，因而零件具有良好的贴模性并能获得很高的内径精度。

This article introduces the design of louver tooling for turret punch press, mainly focusing on the design and calculation of die, punch body and stripper plate.

介绍了多工位数控冲床用百页窗模具的设计，重点介绍了下装凸模、上装镶拼凹模及卸料板的设计和计算方法。

The press process of blanking,drawing, perforating, flaring, trimming are adopted. In this paper, the process suitability of part is analysed. The process parameters, such as blank layout and press force are calculated. The general construction of mold and main parts are designed. The compound die of blanking,drawing,perforating and the simple press tool of flaring,trimming and detail drawings of main parts are drawn.

设计中分析了工件的冲压工艺性，对毛坯排样、冲压力、刃口尺寸等进行了计算，并且对模具相对应的凸模和凹模进行了强度校核，以及模具总体结构、主要零部件的选择与设计，绘制了落料、拉深、冲孔复合模和翻边、切边的单工序模具装配图和模具的主要零件图。

Punch and Die blanking punch were different plate fixed to facilitate adjustment gap; Punch and Die blanking die is used overall fixed plate.

模具的冲孔和落料凸模分别用不同的固定板固定，便于调整间隙；冲孔凹模和落料凹模则采用整体固定板固定。

A three-dimensional finite-element model, which includes plate, punch, die and holder pad, is established to simulate the drawing process based on the characteristics of the square box part.

根据方盒形件的特点，本文建立了包括板料、凸模、凹模以及压边圈在内的三维有限元分析模型。

A quarter model is used to simulate for the reason of symmetry. Punch, die and holder pad are regarded as rigid body because of little deformation.

考虑到对称性，取四分之一模型进行有限元模拟，由于凸模、凹模以及压边圈变形都很小，故将其视为刚体。

But in practice, due to the condition and tradition, for both the blanking and punching, the usual way is to produce punch first and then the die plate, or in the opposite way, so the conversion between them is needed.

但在实际生产中，由于条件和习惯的原因，部分工厂采用不分落料、冲孔，均是先制造凸模，再配制凹模，或者反之，这样就需要进行换算。

It was slump-molded styrene over a fibreglass body mold that had been sent over with one of the costume shipments and discarded.

它是用凸模法在一个玻璃纤维模体上喷涂苯乙烯，模体是和一批服装货物一起送来的，然后被我废物利用了。

The opposite hydraulic pressure tension is a sheet forming method,using the reverse hydraulic pressure established during the raised mold and sheet enters the concave mold.

对向液压拉深是在凹模兼液压室的型腔内充满液体，利用凸模带动板料进入凹模后建立的反向液压而使板料成形的方法。

In this paper, by using the electromagnetic forming unit developed by ourselves, the influence of various parameters such as the thickness of elastomer, the diameter of the punch, the value of sorap and the installation form of the punch on the minimum discharge energy of blanking were studied on the base of experiments.
