Problems solved by technology

Adopt the form of simultaneous internal and external heating, that is, use the external heating method of simultaneous heating of the upper and lower furnaces on the outside of the mold and the heating method of compensation heating of the inner furnace mold core to heat the mold from the outside to the inside at the same time, and heat from the inside to the outside. The normal heating speed also solves the problem of the influence of large temperature gradient changes on the mold and the problem of thermal sensitivity of the k403 material during heating

Embodiment Construction

[0020] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0021] See attached figure 1 , 2 Shown, this kind of mold heating furnace for isothermal forging is characterized in that:

[0022] (1) The heating furnace mainly includes an outer furnace 1 and an inner furnace 2. The outer furnace 1 is a large annular structure. The surrounding structure of the circular inner cavity is divided into a furnace shell 3, an insulation layer 4 and a refractory layer 5, and the outer furnace 1 is divided into two parts with the same upper and lower heights, namely the upper outer furnace body 11 and the lower outer furnace body 12;

[0023] The inner furnace 2 is a cylindrical body composed of a refractory layer 5, which is set in the center of the inner cavity of the outer furnace 1. The outer circle size of the cylindrical body is based on the outer circle of the inner furnace 2 cylindrical b...

Abstract

The invention relates to a mould heating furnace for isothermal forging. The mould heating furnace is characterized in that: (1) the heating furnace mainly comprises an outer furnace and an inner furnace, the outer furnace has a large annular structure, and the inner furnace is a cylindroid consisting of a fireproof layer and is sleeved in the center of the inner cavity of the outer furnace; and (2) an outer furnace heating element is made of resistance wires which are annularly equidistantly distributed on the inner edge surface of the inner cavities of the upper furnace body and the lower furnace body from up to down; and an inner furnace heating element is made of a resistance belt; and the resistance belt is wound into a loop shape and is uniformly hung on the outer surface of the cylinder of the inner furnace. Compared with the prior art, the heating furnace heats large and super-large circular overall frame isothermal forging moulds with single holes, ensures the normal heating speed and solves the problems that large temperature gradient change influences the moulds and k403 materials have thermosensitivity when heated.

Description

technical field [0001] The invention relates to a mold heating furnace for isothermal forging, which belongs to the technical field of forging heating. The mold heating furnace is a new structural design, which better realizes the heating of a certain integral frame mold for an aero-engine, and satisfies the requirements of the mold for isothermal forging. requirements. Background technique [0002] A certain machine structural frame forging is a typical single-hole circular frame forging. It has many horns and thin webs. It was originally welded by 6 die forgings and has 6 welds. This will inevitably affect the quality of the forging. Eliminating the welding seam and changing the combined frame to the integral frame isothermal forging is the development direction of this type of forging, and then designing a thinner component section can greatly reduce the weight of the aircraft structure (about 20%) and improve the efficiency of the aircraft structure. At the same time, it...
