Numerical control positioning system for door frame keyhole of steel door

Abstract

The invention provides a numerical control positioning system for a door frame keyhole of a steel door. The numerical control positioning system consists of a steel door frame keyhole numerical control positioning electric control device and a steel door frame keyhole numerical control positioning device. By using the numerical control positioning system provided by the invention, numerical valuesof lifting legs are input to a program in a PLC control panel of the steel door frame keyhole numerical control positioning electric control device and locating pins of locating mechanisms positionedat the left and right sides of the steel door frame keyhole numerical control positioning device can be automatically moved to corresponding positions, and operation can be ended by just pressing a run button, thus the punching efficiency of sheet metal parts which are the same in size and are punched for a plurality of times is improved; the quantity of operators is reduced; errors generated inan operation process are reduced; the punching precision of a product is improved; and the dimensional precision is improved. Moreover, the operation can be implemented without a professional person,and a single person can independently implement the operation even when the sheet metal parts are relatively long. The numerical control positioning system provided by the invention can realize multi-time punching and man-computer combination, implements the operation efficiently, can also realize full-automatic production and is also universal to most of the sheet metal parts.

Description

technical field [0001] The invention belongs to mechanical manufacturing technology, relates to mold manufacturing, mechanical manufacturing technology and the improvement of punching and positioning technology for sheet metal parts, in particular to a numerically controlled positioning system for lock holes of steel door frames. Background technique [0002] In the current industry, the punching and cutting of sheet metal parts and the positioning of door frame lock holes are basically realized by steel rulers or several positioning rods (locating pins) or fully automatic numerical control systems. For sheet metal parts that have been punched and cut many times on the same mold Most of the time can only be realized by looking at the steel ruler or using many positioning pins, but using the steel ruler to realize punching and cutting positioning requires professionals to operate. At the same time, this so-called professional needs to be trained for more than half a year. to ...
