Gantry type numerical control flame cutting machine

Abstract

The invention discloses a double column type numerical control flame cutting machine, comprising a control system, a power distribution cabinet, a gas control cabinet, two heavy rails and a gantry fixed on two end frames; wherein rail webs at one side of the two heavy rails are respectively internally provided with longitudinal gear racks, the two end frames are respectively provided with a longitudinal servo motor, the gantry is connected with multiple cutting torches which can move synchronously under the driving of a traverse servo motor; and the cutting torches are connected with the gas control cabinet by a separation panel. The longitudinal servo motor and the traverse servo motor can carry out precise control and cut any pattern; the two end frames walk synchronously and the gantrycan be precisely positioned; the high and low pressure of the preheated gas is adjusted to realize high pressure preheating and low pressure preheating; and cutting oxygen can carry out multistage perforation, increase perforation thickness and reduce splashing steel slag. The invention solves the technical problems that the two end frames of the existing double column type numerical control flame cutting machine do not walk synchronously, the preheating time is long and the perforation effect is poor, can effectively improve the cutting precision and the work efficiency and has stable and reliable structure.

Description

(1) Technical field: [0001] The invention relates to a numerical control cutting machine, in particular to a gantry type numerical control flame cutting machine. (two), background technology: [0002] CNC cutting is to use digital programs to control the movement of the machine tool. When the machine tool moves, the cutting tool that comes with it cuts the object. This kind of mechatronic cutting machine is called CNC cutting machine. The existing gantry-type CNC flame cutting machine generally adopts the vertical structure of the double-underframe beam seat of the traditional large and medium-sized machine tool, and the span and longitudinal travel distance are large, which is suitable for large-scale plate processing; generally, gas and oxygen are used to locally heat the workpiece through combustion , so that it reaches a molten combustion state, and then use cutting oxygen to perform cutting and piercing operations; there are generally disadvantages such as low cutting a...

Problems solved by technology

The existing gantry-type CNC flame cutting machine generally adopts the vertical structure of the double-underframe beam seat of the traditional large and medium-sized machine tool, and the span and longitudinal travel distance are large, which is suitable for large-scale plate processing; generally, gas and oxygen are used to locally heat the workpiece through combustion , so that it reaches a molten combustion state, and then use cutting oxygen to perform cutting and perforation operations; there are generally disadvantages such as low cutting accuracy, low cutting speed, long cutting warm-up time, long perforation time, and imprecise perforation.

At the same time, the two-sided walking of the gantry flame cutting machine is inconsistent, which is prone to twisting and jamming, which affects the cutting accuracy, and even causes cutting interruption and workpiece scrapping
