Double-head cutting saw

Abstract

The invention relates to a double-head saw used in cutting, which comprises machine base, control tank, work platform on the machine base, wherein the platform has blank mould and gas top for fixing the work piece; the platform is fixed with cutting saw for cutting work piece, the control top for controlling the cutting, feeding gas top; the cutting saw comprises the first cutting saw at the left of platform and the second cutting saw at the right of platform; the control top and the first cutting saw have connecting rod between to control the cutting strike; the first and second cutting saws are connected with transmission rod, while they are connected to the control tank; the first and second cutting saws can cut two ends at one time, to confirm the flatness. The invention can improve the quality with uniform welding.

Description

technical field [0001] The invention relates to a mechanical device for cutting a heating radiator elbow, in particular to a double-head saw for cutting. Background technique [0002] At present, the steel cylindrical radiator is widely used in the HVAC industry. The traditional steel cylindrical radiator is bent by cutting the angle of the pipe. The saw is clamped twice and the corners are cut twice. The disadvantage is that because a radiator elbow is positioned and cut twice, the process is cumbersome, the production efficiency is low, the labor intensity is high, and the shape and position tolerance and dimensional accuracy are difficult. To meet the requirements of the process standard, the radiator elbow processed by this method is prone to inaccurate butt welds between the radiator and the header pipe after assembly, the weld quality is poor and unsightly, the heat affected zone is large during the welding process, and the stress Concentration, it is easy to appear l...

[0002] At present, steel cylindrical radiators are widely used in the HVAC industry. The traditional steel cylindrical radiator bends and cuts corners. The method is to use a grinding wheel cutting machine or a disc The saw is clamped twice and the corners are cut twice. The disadvantages are: because a radiator elbow is cut twice, the process is cumbersome, the production efficiency is low, the labor intensity is high, and the shape tolerance and dimensional accuracy are difficult. To meet the process standard requirements, the radiator elbow processed by this method is prone to loose butt welds between the heat sink and the header pipe after assembly, poor weld quality and unsightly welds, large heat-affected zone during welding, and stress Concentrated, prone to large welding stress deformation
