Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 5As shown, an embodiment of the present invention provides a production line for heat treatment using forging waste heat, and the production line for heat treatment using forging waste heat includes a forging device 10, a feeding device 20, a continuous heat treatment furnace 30 and a transfer assembly 40, wherein the forging device 10 has a forging station; the feeding device 20 includes a transfer vehicle 21, an annular feeding rail 22 and a feeding tray, the annular feeding rail 22 can drive the feeding tray to move along its extension direction, the annular feeding rail 22 has a feeding station and a transfer station, and the transfer vehicle 21 is movably arranged between the forging station and the feeding station; the forging device 10 and the continuous heat treatment furnace 30 are respectively arranged at both ends of the feeding device 20, and the continuous heat treatment furnace 30 includes a furnace body 31, an annular heat treatment rail 32, a plurality of carrier vehicles 33 and A driving member 34, a furnace body 31 having a furnace chamber and a furnace entrance door and a furnace exit door connected to the furnace chamber and arranged opposite to each other along the length direction of the furnace chamber, a ring-shaped heat treatment rail 32 passing through the furnace chamber along the length direction of the furnace chamber and extending out of the furnace chamber, a plurality of carrier vehicles 33 are arranged on the ring-shaped heat treatment rail 32, and the driving member 34 can drive the plurality of carrier vehicles 33 to move along the extension direction of the ring-shaped heat treatment rail 32; a transfer assembly 40 is arranged between the ring-shaped loading rail 22 and the ring-shaped heat treatment rail 32, the transfer assembly 40 includes a transfer rail 41 and a transfer gripper 42 movably arranged on the transfer rail 41, the portion of the ring-shaped heat treatment rail 32 extending out of the furnace chamber has a material receiving station and a material unloading station, and the transfer gripper 42 has a transfer position corresponding to the transfer station and a material receiving position corresponding to the material receiving station.

[0031] By applying the technical solution of the present invention, a production line for heat treatment using forging waste heat includes a forging device 10, a loading device 20, a continuous heat treatment furnace 30 and a transfer assembly 40. When the production line is used to heat treat the upper core plate, the upper core plate forged by the forging device 10 at the forging station is transferred to the loading tray at the loading station by the transfer vehicle 21, and the loading tray is moved to the transfer station along the annular loading rail 22. The transfer gripper 42 is moved along the transfer rail 41 to the transfer position corresponding to the transfer station, and the transfer gripper 42 is used to transfer the upper core plate located on the loading tray to the carrying vehicle 33 located at the receiving station of the annular heat treatment rail. The driving member 34 is used to drive the carrying vehicle 33 to move along the extension direction of the annular heat treatment rail 32, so as to heat treat the upper core plate in the furnace cavity of the furnace body 31, and the heat-treated upper core plate is unloaded at the unloading station, thereby completing the heat treatment process of the upper core plate. Compared with the method in the related art in which the upper core plate needs to be cooled first when heat treating the upper core plate, the production line can effectively utilize the residual heat of the upper core plate after forging, thus saving energy.

[0032] It should be noted that the transfer vehicle 21 can move along its track.

[0033] Among them, the loading equipment 20 includes multiple loading pallets, which are arranged at intervals on the annular loading rail 22. After the transfer gripper 42 transfers the upper core plate on the loading pallet to the carrying vehicle 33, the loading pallet continues to move along the extension direction of the annular loading rail 22 to reload the next forged upper core plate.

[0034] Specifically, the annular heat treatment rail 32 includes a heat treatment section and a transfer section connected to each other. The heat treatment section passes through the furnace along the length direction of the furnace, and the transfer section is located outside the furnace. The material receiving station and the material unloading station are both arranged on the transfer section. The transfer section includes a furnace-out transfer section, a loading and unloading transfer section and a furnace-entering transfer section which are connected in sequence, and each section is arranged in a straight line. The furnace-out transfer section and the furnace-entering transfer section are arranged at an angle to the loading and unloading transfer section and are located on the same side of the loading and unloading transfer section. The furnace-out transfer section corresponds to the furnace-out door, and the furnace-entering transfer section corresponds to the furnace-entering door. The loading and unloading transfer section has the same extension direction as the heat treatment section. The driving component 34 includes a transfer vehicle and a push-pull cylinder. The furnace-out transfer section, the loading and unloading transfer section and the furnace-entering transfer section are each provided with a transfer vehicle. The carrying vehicle is arranged on the transfer vehicle and moves with the transfer vehicle along the extension direction of the annular heat treatment rail. A push-pull cylinder is respectively arranged on one side of the furnace-out transfer section away from the loading and unloading transfer section and the furnace-out door, and a push-pull cylinder is respectively arranged on one side of the furnace-entering transfer section away from the loading and unloading transfer section and the furnace-entering door. The push-pull cylinder can drive the transfer vehicle to move among the furnace-out transfer section, the loading and unloading transfer section, the furnace-entering transfer section and the heat treatment section.

[0035] Among them, a heat insulation assembly is arranged in the furnace of the continuous heat treatment furnace 30, and the heat insulation assembly includes a heat insulation member extending along the length direction of the furnace, and the upper surface of the heat insulation member can fit with the side wall of the furnace and the carrier. A heating element is arranged on the side wall of the furnace, and the upper core plate needs to be kept warm at 950°C for 1 hour in the furnace. Compared with the use of a trolley furnace for normalizing the upper core plate, which takes 2 hours for heat treatment, the use of a continuous heat treatment furnace can effectively save energy.

[0036] Specifically, a plurality of carriers 33 are located on the annular heat treatment rail 32, some of the carriers 33 are located outside the furnace, and the remaining carriers 33 are arranged in sequence along the length direction of the furnace. In this embodiment, there are 13 carriers 33. During the heat treatment process, one carrier 33 is located on the transfer section outside the furnace, and 12 carriers 33 are located on the heat treatment section inside the furnace. When the heat treatment of the upper core plate in one carrier 33 located on the heat treatment section is completed and the upper core plate is discharged from the furnace door under the pull of the push-pull cylinder, the carrier 33 located on the transfer section enters the heat treatment section under the push of the push-pull cylinder, and the heat treatment is performed again, thereby realizing the continuous heat treatment of the upper core plate.

[0037] In this embodiment, the annular loading rail 22 includes two rails and two lifting mechanisms. The two rails are spaced apart in the height direction. The two lifting mechanisms are respectively located at both ends of the two rails to move the loading tray between the two rails. The loading station is located on one of the lifting mechanisms, and the transfer station is located on the upper rail. The annular loading rail 22 with the above structure has the advantages of simple structure and easy installation.

[0038] Specifically, the transfer vehicle 21 transfers the forged upper core plate to the transfer station on the upper track, the loading tray moves along the upper track to the loading station, and the upper core plate on the loading station is moved to the carrier vehicle 33 by the transfer gripper 42. After unloading, the loading tray descends to the lower track under the action of the lifting mechanism, and moves along the lower track to the loading station of another lifting mechanism.

[0039] The two tracks are spaced apart in the height direction, which means that one of the tracks is located above the other track, and the transfer station is located on the track above.

[0040] In this embodiment, the track includes a track frame and a plurality of track rollers arranged on the track frame and capable of rotating, the track frame extends along a straight line, and the plurality of track rollers are arranged at intervals along the extending direction of the track frame. The track adopting the above structure has the advantages of simple structure and easy installation.

[0041] like Figure 5 As shown, the track frame includes a first frame and a second frame arranged at intervals, and track rollers are arranged on the first frame and the second frame. The production line for heat treatment using forging waste heat also includes a cooling mechanism 50, and the cooling mechanism 50 includes a push cylinder, a cooling frame 51, a cooling cover 52, and a fan 53 arranged on the cooling cover 52. The cooling frame 51 is arranged between the first frame and the second frame and extends in a straight line. The cooling cover 52 is arranged on the cooling frame 51 and extends along the axis of the cooling frame 51. The cooling cover 52 is connected to the outlet of the fan 53. The push cylinder can abut against the loading tray to drive the loading tray to move along the extension direction of the cooling frame 51. The cooling mechanism 50 can be used to cool the upper center plate to meet the temperature required for heat treatment.

[0042] In this embodiment, the continuous heat treatment furnace performs a normalizing process on the upper core plate. The temperature of the forging waste heat before the heat treatment of the upper core plate needs to be controlled between 400°C and 600°C, which can complete the structural transformation of the upper core plate after forging and effectively utilize the forging waste heat for subsequent heat treatment. Before entering the continuous heat treatment furnace 30, an infrared thermometer is used to measure the temperature of the upper core plate to adjust the fan air volume of the cooling mechanism 50 to control the waste heat temperature.

[0043] Specifically, the loading tray moves to the first frame under the action of the lifting rollers of the lifting mechanism, and moves to the cooling rack 51 under the action of the track rollers, and is cooled to 500°C to 600°C under the action of the fan 53. At the same time, the pushing cylinder pushes the loading tray to move on the cooling rack 51 along its extension direction, and moves the loading tray to the second frame, and moves to the lifting mechanism under the action of the track rollers.

[0044] Specifically, the push cylinder includes a cylinder body and a push rod movably arranged in the cylinder body, the cylinder body is arranged between the first frame body and the cooling frame 51, a plurality of rotatable push rollers are arranged on the cylinder body, and the push rod can abut against the loading tray. The push cylinder adopting the above structure has the advantage of simple structure.

[0045] In this embodiment, a pushing plate is provided on the upper surface of the pushing cylinder, and the pushing roller is provided on the pushing plate.

[0046] Specifically, the upper surface of the pushing plate is flush with the upper surface of the first frame, and the loading tray can move along the extension direction of the pushing cylinder under the action of the pushing roller.

[0047] The lifting mechanism includes a lifting frame, a plurality of lifting rollers and a lifting cylinder, the lower end of the lifting frame is connected to the ground, the plurality of lifting rollers are rotatably arranged at the upper end of the lifting frame in a horizontal direction, and the lifting cylinder is drivingly connected to the lifting frame. The lifting mechanism adopting the above structure has the advantage of simple structure.

[0048] In this embodiment, the lifting structures and lifting rollers at both ends of the track rotate in opposite directions.

[0049] like Figure 3 As shown, the transfer gripper 42 includes a transfer frame 421, a transfer cylinder 422 and a gripper body 423. The transfer frame 421 is arranged on the transfer rail 41. The transfer cylinder 422 is connected to the gripper body 423 to make the gripper body 423 move vertically. The gripper body 423 can grab the upper center plate. The transfer gripper 42 with the above structure has the advantage of simple structure.

[0050] Specifically, the transfer rail 41 is located above the annular loading rail 22 and the annular heat treatment rail 32. When the transfer gripper 42 moves along the extension direction of the transfer rail 41, it moves between the top of the annular loading rail 22 and the top of the annular heat treatment rail 32. Moreover, when the transfer gripper 42 moves to the top of the annular loading rail 22 or the top of the annular heat treatment rail 32, the transfer cylinder 422 drives the gripper body 423 to rise or fall vertically to grab the upper center plate.

[0051] like Figure 3As shown, the gripper body 423 includes a connecting plate 424, a plurality of transport claws 425 and a plurality of transport claw cylinders 426. The transport oil cylinder 422 is drivingly connected to the connecting plate 424. The plurality of transport claws 425 are arranged at intervals along the circumference of the connecting plate 424. Each transport claw 425 is hinged to the connecting plate 424. The plurality of transport claw cylinders 426 are drivingly connected to the upper ends of the plurality of transport claws 425 in a one-to-one correspondence. The gripper body 423 adopting the above structure has the advantages of simple structure and reliable operation.

[0052] Specifically, when the transfer claw cylinder 426 drives the transfer claw 425 to move, the transfer claw 425 can rotate with the hinge axis of the transfer claw 425 and the connecting plate 424 as the hinge point, thereby realizing the mutual approach and separation of multiple transfer claws 425.

[0053] like Figure 4 As shown, the loading device 20 includes a plurality of loading trays, and the loading device 20 also includes a stacking mechanism 24 arranged above the annular loading rail 22, the stacking mechanism 24 includes a stacking frame 241, a stacking cylinder 242 and a stacking gripper 243, the stacking frame 241 is arranged on the annular loading rail 22, the stacking cylinder 242 is driven and connected with the stacking gripper 243 so that the stacking gripper 243 moves vertically, and the stacking gripper 243 includes a plurality of stacking claws 244 that can movably grasp a plurality of upper core plates. The stacking mechanism 24 can be used to stack a plurality of upper core plates, so that the plurality of upper core plates are stacked into a stack and then transferred to the carrier 33, so that each carrier 33 can simultaneously transport a plurality of upper core plates to the continuous heat treatment furnace 30.

[0054] Specifically, when the upper center plate is moved to the bottom of the stacking mechanism 24 through the loading tray, the upper center plate can be grabbed by the stacking gripper 243, and the stacking gripper 243 can grab multiple upper center plates at the same time, that is, when multiple loading trays pass under the stacking mechanism 24 along the annular loading rail 22 in turn, one upper center plate can be grabbed by the stacking gripper 243, and then the upper center plate is placed on the top of the next upper center plate and grabbed again by the stacking gripper 243. When the third When the upper core plate moves to the bottom of the stacking gripper 243, the first two upper core plates can be placed above the upper core plate and grabbed again by the stacking gripper 243, until the stacking gripper 243 grabs 5 upper core plates at the same time, and the 5 upper core plates are transported to the loading station together by the loading tray again, and moved to the carrier 33 by the transfer gripper 42. The upper core plates on each carrier 33 are arranged in a single row, which can ensure that the upper core plates are heated evenly in the continuous heat treatment furnace. However, when using a trolley furnace, a large number of upper core plates will be placed each time the heat treatment is performed, and the upper core plates are arranged in an array in the furnace of the trolley furnace, which can easily cause uneven heating of the upper core plates close to the furnace wall and far away from the furnace wall, resulting in poor heat treatment effect.

[0055] In this embodiment, when the forging cycle of the upper core plate is 2 minutes per piece, the automatic stacking after forging is 5 pieces per stack, and the heat treatment cycle is 10 minutes per stack. For the upper core plate production equipment using other forging cycles, the heat treatment production cycle can be determined by matching the upper core plate forging cycle with the number of stacking before heat treatment to perform normalizing heat treatment, and pass through the heat treatment production line furnace in a single row to ensure uniform heating of the forged upper core plates.

[0056] like Figure 2 As shown, the feeding device 20 further includes a centering mechanism 25 located below the palletizing mechanism 24. The centering mechanism 25 can center the upper center plate on the feeding tray with the upper center plate on the palletizing mechanism 24. The centering mechanism 25 includes a plurality of movable centering claws 251. The plurality of centering claws 251 are arranged at intervals along the circumference of the upper center plate on the annular feeding rail 22. The centering mechanism 25 can be used to center the plurality of upper center plates so that the centers of the plurality of upper center plates are on the same straight line, so as to transport the plurality of upper center plates after palletizing.

[0057] It should be noted that the driving structure and driving method of the centering claw 251 and the stacking claw 244 are the same as the driving structure and driving method of the transfer claw 425.
