[0026] The use method and advantages of the present application: the low-nitrogen non-oxidizing industrial furnace for calcining plate spring parts in working, the working process is as follows: As Figures 1 to 9As shown, the leaf spring is inserted into the installation opening of the furnace cover 604 and extends into the clamping chamber 701. By starting the hydraulic cylinder 501, the hydraulic cylinder 501 drives the hydraulic rod 502 to start to contract, and the hydraulic rod 502 drives the rotating block 601 to slide in the sliding groove through the connecting sleeve 503. Under the abutting force of the linkage rod 603 and the guide rail 208, the linkage disk 602 drives the rotating block 601 to start to rotate. At the same time, the linkage rod 603 drives the trigger block 801 to deflect, and the trigger block 801 drives the trigger rod 802 to deflect. After the trigger rod 802 abuts against the abutting block 209, it enters the trigger groove and pushes the trigger block 801 to slide on the outer wall of the linkage rod 603, so that the trigger block 801 pulls the sliding block 804 to slide in the furnace cover 604 through the sliding rod 803. When the cam 705 is in contact with the gear 302, the spring 706 will move in the direction of the left and right sides of the gear 303, and the spring 706 will move in the opposite direction to the left and right sides of the gear 303. When the rod 410 is deflected, the abutting rod 410 will drive the pressure plate 411 to rotate to one side of the clamping ring 708. At this time, the connecting rod 605 abuts against the outer wall of the upper push ring 407 and pushes the upper push ring 407 to move in the direction of the downward push ring 405. The upper push ring 407 drives the lower push ring 405 to slide through the connecting rod 406. The lower push ring 405 drives the pushing block 402 to disengage from the lower rotating ring 305 through the pushing plate 404 and makes the sealing disk 403 abut against the inner wall of the furnace body 202. At the same time, the pushing block 402 triggers the trigger switch provided in the pushing chamber 401, and the electric heating tube starts to work. At the same time, the pressure plate 411 pushes the clamping ring 708 to move in the direction of the furnace body 202, so that the clamping head 705 is unlocked from the outer wall of the leaf spring, and under the pushing action of the clamping rod 707 The leaf spring moves into the furnace body 202. After preheating is completed, the PLC board controls the electric heating tube to stop working and starts the gas furnace 102. The gas furnace 102 introduces the gas into the leak tube 203 through the gas pipe 103. The spark plug 204 completes the ignition of the gas. At the same time, the protective gas in the protective gas bin 107 enters the injection pipe 205 from the outlet pipe 108 via the pressure pump. After the pressurized gas is ejected from the injection pipe 205, it will push the blade 302 to drive the upper rotating ring 301 and the lower rotating ring 305 to rotate in the furnace body 202. Under the meshing action of the gear 303 and the toothed disc 206, the leaf spring rotates while revolving, so that the heating of the leaf spring is more uniform. After the furnace body 202 absorbs heat, it is introduced into the heat conducting pipe 106 to heat the water in the steam furnace 104. After calcination is completed,The steam in the steam furnace 104 enters the drain tube 203 through the steam pipe 105, and the steam blows away the residue attached to the surface of the leaf spring to avoid any waste residue.
