The cam system and processing method of stamping frame connecting plate equipment

Abstract

Provided is a CAM system of a stamping frame connecting plate device and a machining method. The CAM system is characterized by comprising a pretreatment and die database management module, an automatic adaptive die module, an optimization module, an automatic edge-tracing module, an NC program creating module and an analog simulation module. The pretreatment and die database management module puts connecting plate data and die database data in corresponding arrays respectively. The automatic adaptive die module conducts automatic die adaption on all effective data in the arrays according to a traditional adaptive die method or a long-round-hole adaptive die method and writes the data to a connecting plate graphics library. The optimization module reads data of the automatic adaptive dies to treat dies matched with the traditional adaptive die method or the long-round-hole adaptive die method. The automatic edge-tracing module treats irregular plates, then performs the steps of NC program creating, analog simulation and the like to form a punching program suitable for a stamping connection plate device and transmits the program to a numerical control connecting plate punching device for production and machining.

Description

technical field [0001] The invention relates to the technical fields of mechanical design, control system and computer-aided manufacturing of numerical control punching equipment, in particular to a CAM system of punching equipment for connecting plate of automobile frame. Background technique [0002] The frame is the installation basis of the various parts of the car, usually composed of longitudinal beams and beams, which connect the parts of the car and bear various loads from inside and outside the car; the connecting plate (ie, the beam) is an important part of the frame. The characteristic of the plate is that the holes range from a dozen to dozens, and the new connecting plate has one or several very long oblong holes, which are usually placed horizontally or vertically; the second is that the connecting plate has many It is a special-shaped part. Usually, the processing of these connecting plate parts is manually punched by a punch press or drilled with an electric ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a CAM system for punching frame connecting plate equipment, which makes technical innovations for the shortcomings of traditional connecting plate equipment that cannot process special-shaped plates, and realizes automatic positioning through automatic edge finding; For the long oblong hole, a new automatic tool matching solution is given to achieve the purpose of adapting to the high-speed, high-performance and high-efficiency characteristics of connecting plate stamping, improving the punching speed and precision, and prolonging the life of the die.
