Cutting torch elevator for plasma cutting machine

Abstract

The invention relates to an industrial cutting apparatus, particularly a cutting torch lifting apparatus for a numerical control plasma cutting machine used for cutting medium-thickness metal sheets. The invention aims to provide a cutting torch elevator for a plasma cutting machine, wherein the cutting torch elevator has the advantages of simple structure and high operational safety and has the function of dust prevention. The cutting torch elevator is provided with a screw rod, an elevating seat and a protection plate, wherein the screw rod is installed on a frame and driven by a motor; the elevating seat is matched with the screw rod; a cutting torch device is connected to the elevating seat; the frame is provided with a guide rail which is used for guiding the elevating seat to rise or fall; the elevating seat comprises a rotation pair, a slide block, a slide block connecting plate and a cutting torch seat; the rotation pair is matched with the screw rod in a rotating mode; the slide block is fixedly connected with the rotation pair; the slide block connecting plate is fixedly connected with the slide block; the cutting torch seat is fixedly connected with the slide block connecting plate; the slide block is provided with a notch which is matched with the guide rail on the frame; the cutting torch seat is connected with the cutting torch device; and the protection plate is arranged between the slide block connecting plate and the cutting torch seat and connected with the frame.

Description

technical field [0001] The invention relates to an industrial cutting device, in particular to a cutting torch lifting device of a numerically controlled plasma cutting machine used for cutting medium and thin metal plates. Background technique [0002] In the industrial field, welded structural parts are widely used in all walks of life. Plate cutting is the first step in the welding process and an important process to ensure the welding quality. It can increase the utilization rate of materials by several percentage points, and its social and economic benefits are considerable. Intelligent precision cutting technology can not only ensure the welding quality of products and improve labor productivity, but also greatly reduce the manufacturing cost of enterprise products and shorten the production cycle of products, especially the use of plasma for bevel cutting. From an economic point of view, become more and more important. The cutting precision and surface roughness of ...
