摘 要

冲压是金属塑性成形加工的基本方法之一，它主要用于加工板料零件，所以也称为板料成形。冲压既能够制造尺寸很小的仪表零件，又能够制造诸如汽车大梁、压力容器封头一类的大型零件；既能够制造一般尺寸公差等级和形状的零件，又能够制造精密（公差在微米级）和复杂形状的零件。冲压具有生产率高、加工成本低、材料利率高、操作简单、便于实现机械化与自动化等一系列优点，因此在汽车、机械、家用电器、电机、仪表、航空航天、兵器等生产和发展具有十分重要的意义。

本次设计的题目是单边棍自动送料装置的设计，通过对给定的管材零件进行冲压加工实验，从而了解单边棍自动送料装置的工作原理和结构组成 关键词：冲压；成本；设计；单边棍自动送料装置

Abstract

With the development of science and technology, interdisciplinary mutual infiltration, mutual exchanges between the various industry, extensive use of new structure, new materials, new technology, the sleeve pressing machine is large, efficient, reliable, energy saving, Recently, the use of machinery industry, bearing and shaft sleeve shaft were investigated, found that the shaft, bearings and bushings in the machinery industry is one of the key parts. Come very naturally in the assembly of the installation is also very simple. In the installation if the use of artificial pressure with not only the labor intensity is too large and the size of each other is not easy to ensure the shaft, bearing and shaft sleeve, so the design of a special press be imperative. Graduation project this time is a tube axial compressive loading machine. This paper introduces the theoretical calculation to design sleeve pressing machine structure, working principle and main parts of the strength check and the advantages of the sleeve, pressing machine is efficient, economical, and high safety, stable operation. The overall plan is: the relative position of two axle sleeve on the plane, the motor reducer to provide power through belt drives the screw rod to rotate, and drives the head movement, a nut, a rotary motion of the linear motion of press. Block type safety clutch overload protection with teeth, pressure distribution in the corresponding position of the pipe after drilling through the drilling template.

Keywords：Stamping; cost; design; automatic feeding device of single rod
