Project Description

Course project: 51 pages, 15 Fig., 4 annexes, 13 sources.

Object of study: hexagonal draw, combined flat pattern, disk chever for processing gears and throttle for cutting metric threads.

Purpose: Design the specified tools for machining parts with the specified dimensions and parameters.

In the course design, calculations of all parameters and sizes of the specified tools are given, materials for the manufacture of tools and machines on which processing will be carried out are selected.

Detailed drawings of the investigated tools have been developed.

Introduction

The purpose of this course project is to calculate and design metal cutting tools: hexagonal draw, combined sweep, disk chever for processing gears and a throttle for cutting metric threads.

Stretching is one of the most high-performance part machining processes. The high performance of the sweep process is due to the fact that several tool teeth with a large total length of cutting edges are simultaneously in operation. Stretching allows you to obtain surfaces of high accuracy (6th - 8th accuracy) and low roughness (Ra = 0.630.25 μm).

Combined unfolds are a special tool for combined processing of several holes.

Chevers are used for finishing and finishing of non-heated gear cylindrical wheels. The accuracy of the wheel is increased by one degree during the shift. In this case, the tooth profile, pitch, beating of the toothed rim are straightened and the surface roughness is reduced to. The resistance of the shaver to overwintering is 1015 thousand wheels. Number of crossover points 4-6.

Disk Shaver Calculation

Design input for the DSS Shaver

The following data shall be known for design calculation:

machined wheel module: m = 1.5;

profile angle: α=20˚;

number of teeth: Z1 = 32,

and wheels: Z2 = 64;

wheel angle teeth on the delitelnoyokruzhnosti:β=10˚;

degree of machining of wheels: 8;

materialobrabatyvayemykhkoles: 40XH.

Conclusion

In the course of the performed work, the specified cutting tools were calculated and designed, their working drawings were developed, given in the appendix with indication of limit deviations in the dimensions of parts and roughness on the surface of the tool.
