Embodiment 1

[0038] The present invention provides a large flexible heat treatment automatic production line with a protective atmosphere, such as figure 1 As shown, a computer integrated control management system can be used to implement a mechanized automatic loading and unloading material, the heat treatment process parameters automatically, online monitoring and real-time regulation of a heat treatment automation production line, including large high temperature quenching heating furnace 1, big back fire heating furnace 2, small back Fire heating furnace 3, small high temperature quenching heating furnace 4, water tank 5, oil tank 6, cleaning tank 7, salt water tank 8, organic solvent tank 9, taking a vehicle 10 and a superbatch 11, in addition, there is an intelligent control system.

[0039] Preferably, the three high-temperature quenched heating furnaces are inconsistent, and a high temperature quenching heating furnace 1 having a size of 1.2 × 1 × 1.4 m is comprised of a high-temperatu...

Embodiment 2

[0048] The present invention also provides a heat treatment automated production line process, and the specific steps are as follows:

[0049] Step 1: Check: The operator checks the production line equipment in front of the production line, determines the production line in normal state, with production conditions

[0050] Step 2: Head: The upper mesh is lowered, the operator will support the auxiliary shaft part, put it in the air discharge plate placed on the upper stage, and the upper stage rises to the limited position waiting to take the feed vehicle to remove ;

[0051] Step 3: Process Preparation: The operator enters the automatic control system on the console, the insulation temperature is set to 1040 ° C, the holding time is 60 min, and the water is cold for 10 min. Select the upper material 11, the heat treatment furnace 1 and the water tank 5 for production, and then check the production line peripheral situation to produce production;

[0052] Step 4: Automatic tapping...

Abstract

The invention provides a large flexible heat treatment automatic production line with protective atmosphere and a process thereof. The heat treatment automatic production line can use a computer integrated control management system to realize automatic loading and unloading of a material taking vehicle, automatic execution of heat treatment process parameters, online monitoring and real-time regulation and control. The heat treatment automatic production line comprises: a set of high-temperature quenching heating unit, which is composed of three high-temperature quenching heating furnaces; a tempering heating unit which is composed of four tempering heating furnaces, wherein the heat treatment furnaces are sequentially arranged from right to left as follows: a large high-temperature quenching heating furnace, a large tempering heating furnace, a small tempering heating furnace, a small tempering heating furnace, a small high-temperature quenching heating furnace, a small high-temperature quenching heating furnace and a small tempering heating furnace; and a set of matched high-precision cooling unit which is composed of cooling tanks with different specifications, wherein the cooling tanks are sequentially a clear water tank, an oil tank, a cleaning tank, an oil tank, a saline water tank, a clear water tank and an organic solvent tank from right to left.

Description

Technical field [0001] The present invention belongs to the field of heat treatment, and more particularly to a large flexible heat treatment automatic production line and production method with a protective atmosphere. Background technique [0002] During the heat treatment, aerospace products have the characteristics of "multi-variety, small batch", and the type of heat treatment process is diverse, the parameters are complex and varied, and the heat treatment process mainly includes annealing, normal fire, quenching (solid solution), temper (aging), etc. In the traditional artificial production process, there is a problem: (1) After the heat treatment of the workpiece, the oxidation of the oxide is produced, and there is a large amount of oxidized skin. There is a need for more processing margins. When some carbon steel heat treatment, charcoal needs to be placed in the furnace to improve the workpiece Carbon; (2) The process process depends on manual operation, the controllab...
