The invention provides a shower-type spinning heating device. The shower-type spinning heating device comprises a combustible gas bottle and an oxygen bottle, wherein the combustible gas bottle and the oxygen bottle are connected with a welding torch by a gas pipe and an oxygen pipe respectively; a heating nozzle is arranged at the top end of the welding torch; the interior of the heating nozzle is a combustion chamber; a plurality of fire spray holes are uniformly distributed in the combustion chamber. The shower-type spinning heating device provided by the invention is simple in structure, convenient to implement, specially suitable for heating a rotating blank during a spinning process; due to the arrangement of the heating nozzle with the plurality of fire spray holes, the shower-type spinning heating device is large in heatable area, high in efficiency, and capable of easily achieving the spinning temperature required by the blank and realizing the stabilization and balance of the temperature during the spinning process.
Description
technical field [0001] The invention belongs to a heating device, in particular to a heating device for spinning. Background technique [0002] Spinning is a metal pressure processing method suitable for forming thin-walled hollow rotating parts. Compared with other stamping methods such as sheet metal deep drawing, metal spinning can greatly simplify the process. Some parts that require 6 to 7 times of stamping can often be manufactured by one spinning. Forming advantages are obvious, and it is increasingly widely used in various military industries such as aviation, aerospace, and weapons. However, when spinning materials with poor plasticity such as aluminum alloys, cracks are prone to appear during spinning at room temperature. If the part blank is heated in the heating furnace first, then the blank is taken out from the heating furnace, and then put on the spinning mold for spinning, the temperature of the blank is easy to drop rapidly to Lower than the required form...
