Double-head cutting saw

Abstract

The invention discloses a double-headed saw for cutting, which comprises a machine base and a control cabinet. The cutting saw of the workpiece, the control top used to control the operation of the cutting saw, and the feeding air top. The cutting saw includes a first cutting saw arranged on the left side of the working platform and a second cutting saw arranged on the right side of the working platform. The control top and the A connecting rod for controlling the cutting stroke is provided between the first cutting saws, a transmission rod is provided between the first cutting saw and the second cutting saw, the first cutting saw, the second cutting saw are electrically connected with the control cabinet, the first cutting saw The setting of the saw and the second cutting saw can make the cuts at both ends of the saw be clamped by the mold positioning and clamping once to complete the cut, which ensures the flatness of the cuts at both ends and improves the row position tolerance of the heat sink due to the out-of-tolerance cuts during the assembly. Ultra-tolerance, high product quality, uniform welding joints after assembly.

Description

technical field [0001] The invention relates to a mechanical device for cutting curved pipes of heating radiators, in particular to a double-headed saw for cutting. Background technique [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 Concentration, it is easy to have large welding...
