Description

Technical Field

[0002] Annealing refers to a metal heat treatment process in which the metal is slowly heated to a certain temperature, maintained for a sufficient time, and then cooled at an appropriate rate. There are several types of annealing, such as laser annealing and traditional baking. The purpose of annealing is to reduce hardness and improve machinability; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grains, adjust structure, and eliminate structural defects. To be precise, annealing is a heat treatment process for materials, including metal materials and non-metallic materials. Stress relief annealing is a heat treatment process in which the workpiece is heated to an appropriate temperature below Ac1, and then cooled with the furnace after insulation. The stress relief heating temperature is low, and there is no structural transformation during the annealing process. It is mainly suitable for blanks and parts that have been cut. The purpose is to eliminate residual stress in blanks and parts, stabilize the size and shape of the workpiece, and reduce the deformation and crack tendency of parts during cutting and use.

[0003] At present, after the planer is used to level the valve plate door panel, a stress relief annealing operation is required. Since the stress relief annealing temperature can reach about 600°C, and when the temperature of steel exceeds 300°C, the strength and elastic modulus of steel decrease significantly, and the plasticity increases significantly, the annealed plate door panel will creep during the heat treatment, causing the plate door panel to deform during the annealing process, resulting in the need to level the plate door panel after the annealing of the plate door panel is completed, which increases the labor burden of personnel. Based on this, an annealing treatment device for the plate door panel of an SCR denitrification valve is proposed. Summary of the invention

When one part of the piston warehouse 1301 is exhausted and the other part is exhausted, the exhausted part of the piston warehouse 1301 will blow the gas to the contact part between the leveling roller 1210 and the plug-in door panel through the jet pipe 1308, and the exhausted part of the piston warehouse 1301 will draw the nitrogen in the annealing box 2 into the piston warehouse 1301 through the connecting pipe 1307 and the exhaust pipe 1306, and When another part of the exhaust is performed, the piston chamber 1301 that is partially exhausted will draw nitrogen in the annealing box 2 into the piston chamber 1301 through the exhaust pipe 1306, and the piston chamber 1301 that is partially exhausted will be discharged into the jet pipe 1308 through the connecting pipe 1309, and the jet pipe 1308 will blow the nitrogen toward the contact position between the leveling roller 1210 and the plug-in door panel, so that the hydrogen in the plug-in door panel can be blown out by the nitrogen, thereby improving the efficiency of dehydrogenation of the plug-in door panel, reducing the hydrogen content inside the plug-in door panel, and improving the performance of the plug-in door panel. In addition, in the initial stage of annealing and when the leveling roller 1210 just starts to move, the blowing operation toward the outer surface of the plug-in door panel through the jet pipe 1308 can clean the outer surface of the plug-in door panel, remove the chips on the outer surface of the plug-in door panel after planer processing, and avoid the presence of chips affecting the annealing quality of the plug-in door panel.

[0029] The specific working principle of the present invention is as follows: when it is necessary to anneal the plug-in door panel, open the sealing door 6 and start the electric screw 1002 to make the displacement block 1003 slide in the sliding bin 1001, thereby making the displacement ring 1004 and the rotating ring 1006 move to the end of the annealing box 2. At this time, the leveling mechanism 12 reaches the end of the annealing box 2, and then the plug-in door panel that needs heat treatment and annealing is fixed in the rotating ring 1006 through the leveling mechanism 12. At this time, the threaded rod 1203 is rotated to make the clamping bin 1204 move upward under the action of the limit rod 1202, and then the plug-in door panel is placed between the fixed bin 1201 and the clamping bin 1204. At this time, the threaded rod 1203 can be rotated to make the clamping bin 1204 move downward under the action of the limit rod 1202, and then cooperate with the fixed bin 1201 to clamp and fix the plug-in door panel. At this time, the leveling roller 1210 contacts the door panel of the plug-in door and there is a slight pressure, and the transmission gear 1205 is meshed with the transmission gear 1007. At this time, the electric screw 1002 is started again, so that the displacement block 1003 slides to the middle of the sliding bin 1001 until the displacement block 1003 moves to the middle position of the sliding bin 1001. At this time, the electric screw 1002 can be closed, and the electric telescopic rod 5 is started to make the sealing door 6 seal the feeding bin 4, and then the valves in the air inlet pipe 7 and the exhaust pipe 8 are opened, so that the air inlet pipe 7 injects nitrogen into the annealing box 2, and the gas in the annealing box 2 will be discharged through the exhaust pipe 8 until the inside of the annealing box 2 is filled with nitrogen, and then the valves in the air inlet pipe 7 and the exhaust pipe 8 can be closed, and then the spiral electric heating tube 9 is started to heat the door panel of the plug-in door, thereby achieving the purpose of heat treatment annealing of the door panel of the plug-in door; When the displacement block 1003 moves to the middle position of the sliding bin 1001, the motor 1101 is started at this time to make the rotating shaft 1102 drive the first bevel gear 1103 to rotate, and then the second bevel gear 1104 drives the driving gear 1106 to rotate through the transmission shaft 1105, and the rotation of the driving gear 1106 will drive the rotating ring 1006 to rotate through the rotating gear 1107, so that the plug-in door panel located in the leveling mechanism 12 rotates, and the rotation of the plug-in door panel will make the internal gas of the annealing box 2 in a flowing state, so that the spiral electric heating tube 9 can evenly heat all the gas inside the annealing box 2, thereby ensuring the uniformity of the internal temperature of the annealing box 2, thereby ensuring the uniformity of the heating of the plug-in door panel, making the temperature of all parts of the plug-in door panel relatively uniform, preventing the uneven temperature of the plug-in door panel from affecting the quality of the heat treatment annealing of the plug-in door panel, and ensuring the uniformity of the structure of the plug-in door panel after the heat treatment annealing, and the quality of stress relief; When the rotating ring 1006 rotates, since the transmission gear 1007 is meshed with the gear ring 1005, and the transmission gear 1007 is rotatably connected in the rotating ring 1006, the transmission gear 1007 will rotate, and then drive the conveying gear 1206 to rotate through the transmission gear 1205, so that the first reciprocating screw rod 1207 rotates, and the rotation of the first reciprocating screw rod 1207 will cause the two sliders 1208 to slide back and forth in the fixed bin 1201 and the clamping bin 1204, and then drive the leveling through the rotating rod 1209. Roller 1210 rolls back and forth along the upper and lower surfaces of the plug-in door panel, so that the leveling roller 1210 can level the plug-in door panel, preventing the creep phenomenon caused by the significant decrease in strength and elastic modulus and significant increase in plasticity of the steel under the action of temperature, which causes the plug-in door to bend and deform, thereby ensuring the flatness of the plug-in door panel during the heat treatment annealing process, avoiding the bending and deformation of the plug-in door panel, ensuring the quality of the plug-in door panel after the heat treatment annealing, reducing the burden on personnel, and improving the quality of the heat treatment annealing; When the leveling roller 1210 rolls along the outer surface of the plug-in door panel, it will drive the rotating rod 1209 to rotate, and then drive the fourth bevel gear 1305 to rotate. The rotation of the fourth bevel gear 1305 will drive the second reciprocating screw rod 1303 to rotate through the third bevel gear 1304, so that the piston plate 1302 slides up and down along the inner surface of the piston warehouse 1301, so that one part of the piston warehouse 1301 divided into two parts by the piston plate 1302 is exhausted while the other part is exhausted. When one part of the piston warehouse 1301 is exhausted and the other part is exhausted, the exhausted part of the piston warehouse 1301 will blow the gas through the jet pipe 1308 to the contact part between the leveling roller 1210 and the plug-in door panel, and the exhausted part of the piston warehouse 1301 will draw the nitrogen in the annealing box 2 into the piston warehouse 1301 through the connecting pipe 1307 and the exhaust pipe 1306, and When another part of the gas is exhausted, the piston chamber 1301 of a part of the exhaust will extract the nitrogen in the annealing box 2 into the piston chamber 1301 through the exhaust pipe 1306, and the piston chamber 1301 of a part of the exhaust will be discharged into the injection pipe 1308 through the connecting pipe 1309, and the injection pipe 1308 blows to the contact part between the leveling roller 1210 and the plug-in door plate so that the hydrogen in the plug-in door plate can be blown out by the nitrogen, thereby improving the efficiency of hydrogen removal of the plug-in door plate, reducing the hydrogen content inside the plug-in door plate, and improving the performance of the plug-in door plate. In addition, in the initial stage of annealing and when the leveling roller 1210 just starts to move, the blowing operation of the injection pipe 1308 to the outer surface of the plug-in door plate can clean the outer surface of the plug-in door plate, remove the chips on the outer surface of the plug-in door plate after the planer processing, and avoid the existence of chips affecting the annealing quality of the plug-in door plate. And because the mass of hydrogen is much smaller than that of nitrogen, the removed hydrogen will be at the top of the annealing box 2, so that when the annealing box 2 is cooled, the hydrogen will not be reabsorbed by the door panel of the plug-in door; After reaching the annealing temperature and keeping warm for a certain period of time, turn off the spiral electric heating tube 9 to reduce the temperature in the annealing box 2 to the specified temperature. At this time, start the electric telescopic rod 5 so that the sealing door 6 cannot seal the feeding bin 4, and then the plug-in door panel can be air-cooled. After cooling to room temperature, start the electric screw 1002 to send the annealed plug-in door panel out of the annealing box 2, and then rotate the threaded rod 1203 so that the clamping bin 1204 cannot clamp the plug-in door panel, and then the annealed plug-in door panel can be taken out.

[0030] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
