设计简介

摘要

本文是在锻压机机架的图样分析后进行锻压机机架的机械加工工艺路线的设计，同时按照其中的加工工序的要求设计夹具。
锻压机机架的主要加工内容是表面和孔。处理路线长，处理时间和处理成本，加工精度要求的零件是加工机械的要求，遵循先面后孔，孔和治疗计划显然是分阶段和粗为了保证加工精度参考选择底面作为粗基准，由一个底部和两个工艺孔作为基准的精度，确定工艺参数不同其治疗和必要的处理。
在一个工件夹持装置，包括零件加工要求的程序和自由度分析是有限的，和表面特性的选定部分的功能定位元件，然后可以选择定位元件限定边界度的测定定位元件的选择也需要一个夹紧元件，最后确定形状的安装结构，特别是。

Abstract

This paper is the design of mechanical machining process route of forging machine in pattern analysis of forging machine and the design process, in accordance with the requirements of the fixture.
The main content of forging machine is processing surface and the hole. The processing route is long, processing time, high processing cost, the machining precision is high. In accordance with the requirements of the machining process, follow the principle of the surface after the first hole, and the hole and the plane processing clearly divided into roughing and finishing stages of processing to ensure accuracy. Reference to the bottom as the benchmark crude, the bottom with two holes as a precision technology base, a variety of process parameters to theprocessing technology and processing were determined..
In parts of fixture design, mainly according to the requirements of machining process, analysis of the degrees of freedom should be restricted, and then according to the characteristics of the selected surface parts of the positioning element, then analysis the selected location of components can be qualified shall be limited degrees of freedom. Determine the positioning components also need to select the clamping element, finally, is to determine the structure of fixture.

Key words: forging machine; process; process; special fixture
