查询词典 punch holder

But sometimes I think if we can put all the centers together like dynamic balance and stripper pressure center of punch holder, vibrate and clamping center of die shoe etc, how perfect it is!

很多时候我在想，如果我能够将所有的中心例如上模的动平衡中心、卸料中心、下模的振动中心、夹钳固定中心等等都放在一条中心线上，那将是一个怎样的境界？

It studied many factors such as blank holder pressure, anti-pressure, clearance between punch and bottom die, and parameters of dentiform on blank holder, analyzed the influence of these factors' change to stress and strain field in distortion area and the appearance of shear crack, summarized the appropriate ratio of blank holder pressure and anti-pressure, and the best range of other factors.

从压边力、反压力、相对冲裁间隙、压边圈齿形参数等各种因素出发，分析了这些因素的变化对于变形区应力应变场与剪切面裂纹产生的关系，并得出了压边力与反压力的合适配合比例，以及其他参数的正确取值范围。

The effects of frictional coefficient and blank holder force and virtual punch velocity on the formability of cross member deep drawing were discussed.

在此基础上讨论了摩擦润滑条件、压边力和凸模的虚拟冲压速度对板料拉深过程的影响。

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。

The draw ratio is the direct relationship between the draw punch and the blank edge—the greater the distance between the draw punch and the blank edge, the greater the resistance to flow, primarily because of the additional surface area of sheet metal clamped between the die face and the blank holder.

拉伸比直接体现在拉延凸模和板料边缘之间的关系--拉延凸模和板料边缘之间的距离越大，限制流动的阻力越大，主要是因为在压边圈和凹模表面间有额外金属板表面被夹紧。

The draw ratio is the direct relationship between the draw punch and the blank edge—the greater the distance between the draw punch and the blank edge, the greater the resistance to flow, primarily because of the additional surface area of sheet metal clamped between the die face and the blank holder.

拉伸率直接体现在拉伸冲头和展开平板边缘之间的关系---拉伸冲头和展开平板边缘之间的距离越大，限制流动的阻力越大，主要是因为在压边圈和模具表面间有额外金属板表面被夹紧。试着用不同尺寸和外形的展开平板进行实验。

On the basis of introducing principle and typical equipments of hydro-forming deep drawing, the HDD has been divided into five typical kinds as follows: hydro-forming deep drawing without punch, deep drawing with fluid assisted blank-holder, deep drawing with hydraulic counter pressure, hydro-mechanical deep drawing, and internal high-pressure deep drawing.

在阐述板料液压拉深方法原理和分析国内外板料液压拉深典型装置的基础上，将板料液压拉深方法分为液压软凸模拉深、液压辅助压边拉深、对冲液压拉深、液压－机械拉深和内高压拉深等5种。

Patented technology of the design of the flexible adjustable punch holder leads to simple adjustment and easy operation.

采用石西公司专利技术--万能调整冲头座技术，冲具调整简单方便，一般师傅就能掌握技术。

Because of the smaller area of the perforators, they have the tendency to dig into the softer punch holder in the absence of a back-up plate.
