Abstract

The invention discloses a shape following-up flexible heating device comprising a flexible heating pipe and an air mixing and distributing mechanism, wherein a mixed light fuel gas output valve and a mixed heavy fuel gas output valve in the air mixing and distributing mechanism are both connected with one end of a mixed fuel gas output hose, and the other end of the mixed fuel gas output hose is connected with the flexible heating pipe; and a compressed air output valve is connected with a pneumatic tool by a compressed air output hose. The device has convenient use, high heat value and uniform and adjustable combustion temperature; for the preheating measure and the preheating effect required in the welding production and other hot-working technologies, the economy, the effectiveness andthe convenience of the device are all superior to those of other prior traditional preheating devices at home and aboard at present.

Description

technical field

[0001] The invention relates to the technical field of conformal flexible heating devices used in the production process of metal components. The conformal flexible heating devices are mainly used for complex-shaped multi-width panels, multi-rib panels, large thickness, special steel, variable cross-section and other large and medium-sized metal components. The heating of circular or linear welds of structural parts and the thermal assembly process required by some machining industries. Background technique

[0002] At present, the heating methods used at home and abroad mainly use torches, flame spray guns or far-infrared crawler-type, rope-type electric heating devices to implement overall or partial point and surface heating on large and medium-sized metal structures with complex shapes. There is always the phenomenon of high energy consumption and uneven heating temperature of the workpiece, which often leads to macro cracks or micro cracks in the worksho...
