Problems solved by technology

[0003] In the prior art, the material is generally heated through a forging furnace, that is, the material is placed in the furnace, and then the material is heated. However, the forging furnace in the prior art has a simple structure, and the heat loss is large during the actual working process, which reduces the The utilization rate of heat increases the cost of using the forging furnace
In addition, in the forging furnace in the prior art, the material is heated unevenly in the forging furnace, which may easily cause quality problems in the forging process of the material

Embodiment 1

[0029] The forging furnace is used to heat the material, which is conducive to the subsequent forging of the material.

[0030] Such as figure 1 , the forging furnace comprises a furnace hearth 1 and a furnace wall 2, a heat preservation cover 3 is arranged on the outer cover of the furnace wall 2, a preheating space 4 is formed between the heat preservation cover 3 and the furnace wall 2, the furnace hearth 1 and the furnace wall 2 The preheating space 4 is connected, and part of the gas circulation process in the furnace 1 enters the preheating space 4 to increase the temperature of the preheating space 4. This scheme can improve the utilization rate of heat, and the material in the preheating space 4 can be Preheating or annealing or other heat treatment of the forged material.

[0031] Such as figure 1 , the forging furnace also includes a fan 5, the fan 5 can input the gas in the preheating space 4 into the furnace 1, the fan 5 can input the gas in the preheating space ...

Embodiment 2

[0039] This example is an optimization of Embodiment 1, and introduces the heating scheme of the preheating space 4 so that the preheating space 4 has a reasonable temperature.

[0040] Such as figure 1 , a heating pipe 10 for heating the gas in the preheating space 4 is arranged in the preheating space 4, a blade 11 for agitating the gas in the preheating space 4 is arranged in the preheating space 4, and the blade 11 is driven by a motor 12 is driven to rotate, and the motor 12 is controlled by the controller 9 to work.

[0041] Such as figure 1 , the blade 11 is fixed on the output shaft of the motor 12, the motor 12 can be fixed outside the heat preservation cover 3, and the output shaft of the motor 12 extends into the preheating space 4, so as to avoid the high temperature in the preheating space 4 from damaging the motor 12, the blade 11 Rotating and agitating the gas in the preheating space 4 makes the temperature of the gas in the preheating space 4 uniform.

Embodiment 3

[0043] This embodiment is a further limitation of Embodiment 2, and introduces the heating tube 10 and the fixing method of the heating tube 10 .

[0044] Such as figure 1 , the heating tube 10 is an electric heating tube, the heating tube 10 is controlled by the controller 9, and the heating tube 10 is arranged in the preheating space 4 in a serpentine shape to extend the length of the heating tube 10, It is beneficial for the heating tube 10 to rapidly heat the gas in the preheating space 4 .

[0045] Such as figure 1 , a groove 13 for accommodating the heating tube 10 is provided on the side wall of the heat preservation cover 3, the heating tube 10 is fixed in the groove 13, and the heating tube 10 is evenly distributed on the heating tube 10 to improve heating The heat sink 14 of the pipe 10 is efficient in dissipating heat.

[0046] The cooling fin 14 can be integrated with the heating tube 10 , and the cooling fin 14 is mainly used to improve the heat dissipation eff...

Abstract

The invention relates to forging equipment, in particular to a forging furnace, and belongs to the technical field of forging. The forging furnace is used for solving the technical problem that a forging furnace in the prior art is large in heat loss. According to the forging furnace, a heat preserving cover is arranged outside the furnace wall in a covering manner; a pre-heating space is formed between the heat preserving cover and the furnace wall; a hearth communicates with the pre-heating space; and high-temperature gas located in the hearth can enter the pre-heating space, and therefore pre-heating can be performed on materials in the pre-heating space or other heat treatment, such as annealing, is performed on the materials. Thus, the utilizing rate of waste heat of the forging furnace is greatly increased. Besides, due to the arrangement of a draught fan, the gas in the pre-heating space can be input into the hearth, the circulating efficiency of the gas in the hearth is improved, and therefore the materials in the hearth are heated uniformly, and the performance of the forging furnace is optimized.

Description

technical field [0001] The invention relates to forging equipment, in particular to a forging furnace, and belongs to the technical field of forging. Background technique [0002] Forging refers to a processing method that does not remove the material to shape the material. In the actual operation process, the material needs to be heated to a certain temperature, and then the material is pressurized to cause plastic deformation of the material, and the material is formed. Therefore, in the field of hot forging, material heating is an essential process for forging. [0003] In the prior art, the material is generally heated through a forging furnace, that is, the material is placed in the furnace, and then the material is heated. However, the forging furnace in the prior art has a simple structure, and the heat loss is large during the actual working process, which reduces the The utilization rate of heat increases the use cost of the forging furnace. In addition, in the fo...
