The lifting assembly 22 includes a lifting cylinder 221, a lifting seat 222, a lifting slider 224 and a lifting guide rail 223. The lifting guide rail 223 and the lifting cylinder 221 are installed on the translation seat 213. The lifting slider 224 and the fork arm 23 are fixed to the lifting seat 222. The lifting slider 224 moves along the lifting guide rail 223. The lifting cylinder 221 drives the lifting seat 222 to move along the lifting guide rail 223, thereby driving the fork arm 23 to rise and fall.

[0026] The solution treatment furnace 3 includes a heating furnace 31, a conveyor belt 32 and a heating furnace connector 33. At least two heating furnaces 31 are arranged in sequence along the direction of the conveyor belt 32. Each adjacent two heating furnaces 31 are connected by a heating furnace connector 33. The conveyor belt 32 is passed through the heating furnace 31 and the heating furnace connector 33.

[0027] The heating furnace 31 includes a furnace body 311, a fan 312 and a heating rod 313. The fan 312 and the heating rod 313 are installed on the furnace body 311. The fan 312 is aligned with the heating rod 313. The fan 312 blows air toward the heating rod 313, so that the hot air generated by heating the heating rod 313 is blown directly into the furnace body 311 for circulation.

Due to the high percentage of chromium and nickel, it has high creep strength and can continue to operate at high temperatures. It has good high temperature resistance. After the two adjacent heating furnaces 31 are deformed under high temperature conditions, the bellows 332 can be deformed as the flange 331 installed on the heating furnace 31 moves, thereby avoiding the high-temperature deformation of the heating furnace 31 and causing breakage when the flange 331 is directly installed, thereby avoiding hot gas leakage. The mounting portion 3311 is provided with a fixed long hole 3314, and the fixed long hole 3314 is arranged in order along the edge of the mounting portion 3311. The screws pass through the fixed long hole 3314 and the sealing ring 333 in turn and are connected and fixed with the feed port or the discharge port of the heating furnace 31, so as to match the different deformation states of the heating furnace 31, so that the conveyor belt 32 can stably transport the workpiece. The positioning portion 3313 includes a positioning rod 3315 and a positioning seat 3316. One end of the positioning rod 3315 is fixed on the connecting portion 3312, and the other end is fixed to the positioning seat 3316. The positioning seat 3316 is provided with a positioning hole 3317. The positioning holes 3317 are arranged in order on the positioning seat 3315. The screws pass through the positioning hole 3317 and are fixed to the base 1, thereby fixing the flange 331 and ensuring that the conveyor belt 32 can stably transport the workpiece.

After completing heating and heat preservation, the discharge lifting door structure 35 is driven to open, and the conveyor belt 32 transports the workpiece to the quenching chamber 4 for quenching.

[0030] like Figure 6 As shown, in this embodiment, the structural dimensions of the feed lifting door structure 34 and the discharge lifting door structure 35 are the same. The feed lifting door structure 34 is taken as an example for explanation. The lifting door structure 34 includes a lifting door bracket 341, a lifting door 342 and a lifting door drive unit 343.
