Abstract
A layer-type mounting-edge integral-forging technology for engine and gas turbine solves the problems of prior art technique which destroys the internal texture of raw material, lowers mechanical and anticorrosion properties and quality, and high cost, etc. It features that after blanking, the material undergoes in sequence upsetting, punching, bridge frame reaming, loop rolling, precasting blank, die forging, cutting, heat-treating, blowing sand and physico-chemical inspecting so that it ensures consistent texture and properties of the forged part, the consumption of raw material and the cost and lowered, and the service life of parts is prolonged.
Description
The present invention is a kind of Forging Technology, particularly engine, gas turbine large mounting edge integrate forging process.
Engine of the prior art, gas turbine large mounting edge Forging Technology its objective is and forges this two classes machine large mounting edge.Its technology generally is blanking, base, die forging, side cut, punching, correction, heat treatment.The blanking that has is that the raw-material centre of monoblock is sliced off; Have plenty of that to make two semicircular arcs earlier welded together with it again.The forging producer of some domestic forging producers and Britain, France, the U.S. uses this technology.Its weak point is to have destroyed raw-material internal organizational structure, causes mechanical performance to descend, and corrosion resistance reduces, and combination property is poor, and is of poor quality.And the cost height, the process-cycle is long.
The objective of the invention is to solve above-mentioned weak point of the prior art, and a kind of engine, gas turbine large mounting edge integrate forging process are provided.
Technical solution of the present invention is: carry out jumping-up, punching, saddle support reaming, looping mill rolling, prefabricated blank, die forging, side cut, heat treatment, cleaning, blast, physics and chemistry detection after the blanking successively.
The advantage that the present invention is had compared to existing technology is: the unanimity that has guaranteed the microstructure and property of forging each several part, thereby improved the service life of part, prolonged the service life of mould, reduced raw materials consumption, reduced the resistance of deformation of forging forming, can the dried heavy forging of skinny device, greatly reduced the part processing cost simultaneously.
The present invention is described in further detail below in conjunction with embodiment: blanking is the disk shape with raw material sawing Cheng Junhou, carries out jumping-up, punching, saddle support reaming then under heated condition, is rolled into the ring base.Prefabricated blank is on the flat-die hammer ring base after rolling to be pressed into trapezoidal base.Die forging is that prefabricated blank forging in forging die is shaped, and needs the spraying glass lubricant before the die forging, and die cavity is lubricated, and to improve the die cavity life-span, promotes each parts of forging to be full of die cavity.The forging of forging and molding is paid after side cut, heat treatment, blast, cleaning, physics and chemistry detection, surface quality, size detection are qualified.Can supply solid forging engine, gas turbine large mounting edge to use.
Claims (2)
1. an engine, gas turbine large mounting edge integrate forging process, comprise that blanking, die forging, side cut, heat treatment, cleaning, blast, physics and chemistry detect, it is characterized in that carrying out jumping-up, punching, saddle support reaming, looping mill rolling, prefabricated blank, die forging, side cut, heat treatment, cleaning, blast, physics and chemistry detection successively after the blanking, blanking is the disk shape with raw material sawing Cheng Junhou, carry out jumping-up, punching, saddle support reaming then under heated condition, be rolled into the ring base, prefabricated blank is on the flat-die hammer ring base after rolling to be pressed into trapezoidal base.
2. engine according to claim 1, gas turbine large mounting edge integrate forging process is characterized in that die forging is that prefabricated blank forging in forging die is shaped, and needs the spraying glass lubricant before the die forging.
