Cutting machine for steel pipe of heat exchanger

Abstract

The invention discloses a cutting machine for a steel pipe of a heat exchanger. The cutting machine comprises a rack, a knife wheel is arranged at one end of the rack and connected with a transmission device, one side of the rack is connected with a sliding rail which is connected with a walking linear bearing, the walking linear bearing is connected to the knife wheel, the rack is connected with a wheel shaft, and a wheel is arranged at each of two ends of the wheel shaft. The walking linear bearing can move on the sliding rail, so that parallel moving of the knife wheel on the rack is realized, walking stroke of the cutting machine is increased, and walking process is stable; due to designing of the wheel shaft, the wheels can be adjusted to enable the rack to rotate around the wheel shaft so as to enable the cutting machine to cut within a plane range, so that cutting range is further expanded, and moving of large workpieces is avoided. The cutting machine is practical, convenient, reasonable in structure and suitable for popularization and application.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a cutting machine for heat exchanger steel pipes. Background technique [0002] Cutting machines are widely used in industrial machinery to cut steel, sheet metal, glass and other workpieces. The existing cutting machines do not have a walking mechanism, and components such as cutter wheels and transmission devices are directly installed on the frame. When using, the steel pipe needs to be cut The machine is placed on the ground or on the work station, and the workpiece is moved to the position where the cutting machine is located. This kind of cutting machine is more convenient when cutting small workpieces, but when it is necessary to cut large workpieces or perform mobile cutting, it will Encountered the problems of limited cutting range, unstable walking, and inconvenient cutting, an online automatic cutting machine with application number 200920064140. It solves the problem of not being...

[0002] Cutting machines are widely used in industrial machinery to cut steel, sheet metal, glass and other workpieces. The existing cutting machines do not have a walking mechanism, and components such as cutter wheels and transmission devices are directly installed on the frame. When using, the steel pipe needs to be cut The machine is placed on the ground or on the work station, and the workpiece is moved to the position where the cutting machine is located. This kind of cutting machine is more convenient when cutting small workpieces, but when it is necessary to cut large workpieces or perform mobile cutting, it will Encountered the problems of limited cutting range, unstable walking, and inconvenient cutting, an online automatic cutting machine with application number 200920064140. It solves the problem of not being stable enough to walk and the walking stroke is short, but the online automatic cutting machine can only move linearly on the base, and still cannot cut within a certain plane range
