DETAILED DESCRIPTION

[0032] In order to make the above objectives, characteristics and advantages of the present application more apparent, a specific embodiment of the present application is described in detail below with reference to the drawings. It should be understood that the specific embodiment described herein is only used to explain the present application and is not used to limit the present application.

[0033] Figure 1 An external structure schematic diagram of the bar homogenizing heating equipment provided for the embodiment, Figure 2 An internal structure schematic diagram of the bar homogenizing heating equipment provided for the embodiment. As shown in Figure 1 and Figure 2 The present embodiment provides a bar homogenizing heating equipment, which comprises a homogenizing furnace 100, a cooling device 200, a hot saw shearing device 300 and a conveying device 400 arranged in sequence along the flow direction of the bar 600, and a holding furnace 500 arranged beside the conveying device 400. The homogenizing furnace 100 comprises a homogenizing shell 110 and a heating device 120 mounted on the homogenizing shell 110. The homogenizing shell 110 is provided with an inlet 111 and an outlet. The interior of the homogenizing shell 110 is provided with a homogenizing flow assembly 130. The inlet 111 is used to receive the bar 600. The homogenizing flow assembly 130 is used to deliver the bar 600 entering the homogenizing shell 110 through the inlet 111 to the outlet and then to the cooling device 200. The heating device 120 is used to heat the bar 600 in the homogenizing shell 110 to a homogenizing temperature. The cooling device 200 is used to cool the received bar 600 to a processing temperature. The hot saw shearing device 300 is used to saw the cooled bar 600 to a set length. The conveying device 400 is used to deliver the bar 600 with the set length to a processing machine (not shown in the figure) for processing production or to the holding furnace 500 for holding.

[0034] When the bar 600 needs to be processed for production, the bar 600 enters the homogenizing shell 110 from the inlet 111. The heating device 120 mounted on the homogenizing shell 110 heats the bar 600 entering the homogenizing shell 110 to a homogenizing temperature, so as to ensure the uniform consistency of the chemical composition and crystal structure of the bar 600. Then, the bar 600 after the homogenizing treatment is flowed by the homogenizing flow assembly 130 and is delivered to the cooling device 200 from the outlet. The cooling device 200 cools the bar 600 to a processing temperature. With the continuous flow of the bar 600, when the bar 600 flows to the hot saw shearing device 300, the bar 600 at the processing temperature is sawed to a set length by the hot saw shearing device 300. The part of the bar 600 with the set length and at the processing temperature is delivered to the processing machine by the conveying device 400 for processing production. The bar 600 with the set length but temporarily not needing processing enters the holding furnace 500 beside the conveying device 400, and is held by the holding furnace 500 at the processing temperature for subsequent processing.

[0035] The bar homogenization heating equipment combines homogenization and heating processes, so that the bar 600 can be processed and produced after being cooled from a homogenization temperature to a processing temperature, thereby eliminating the cumbersome steps in the prior art, i.e., the bar 600 at the homogenization temperature needs to be cooled to room temperature and then transported to a processing production line, and the bar 600 at room temperature needs to be heated to a production temperature before processing and production, thereby reducing processes, making the production line faster and simpler, effectively reducing energy loss in the production process of the bar 600, and reducing time and cost in the process of transporting the bar 600 to the processing production line, and improving production capacity.

[0036] In this embodiment, the bar 600 can be an aluminum bar.

[0037] In this embodiment, the inside of the homogenization shell 110 is provided with a circulating fan. By providing the circulating fan, the heat generated by the heating device 120 can be better diffused to the internal space of the homogenization shell 110, maintaining the uniformity of the internal temperature of the homogenization shell 110 to ensure the homogenization effect. The heating device 120 can generate heat in a natural gas heating manner.

[0038] Please continue to refer to Figure 1 In this embodiment, a closable feeding door 112 is arranged at the position of the feeding port 111. When it is needed to transport the bar 600 to the inside of the homogenization furnace 100, the feeding door 112 is opened. After the transportation of the bar 600 to the inside of the homogenization furnace 100 is completed, the feeding door 112 is closed. The arrangement of the feeding door 112 can ensure the sealing property of the homogenization shell 110 and prevent the heat inside the homogenization furnace 100 from being dissipated outward.

[0039] Figure 3 The inside structure of the homogenization furnace 100 of the bar homogenization heating equipment provided in this embodiment is shown in the schematic view. Please continue to refer to Figure 2 and combine Figure 3 In this embodiment, the homogenization flow transfer assembly 130 can include a homogenization support 131, a feeding roller 132, and a discharging roller 133. Specifically, the support surface 1311 of the homogenization support 131 gradually decreases along the flow direction of the bar 600 inside the homogenization shell 110. The feeding roller 132 is arranged at the higher end of the support surface 1311, and is used to receive the bar 600 entering from the feeding port 111. The feeding roller 132 is movably arranged up and down. After the position of the feeding roller 132 is lowered, the bar 600 is supported on the support surface 1311. The discharging roller 133 is arranged at the lower end of the support surface 1311, and is used to receive the bar 600 rolling off from the support surface 1311 and transport the bar 600 to the cooling device 200.

[0040] The rod 600 is in the process of flowing through the homogenizing furnace 100: the feeding roller 132 receives the rod 600 entering from the feeding port 111, in this process, the length direction of the rod 600 is perpendicular to the axial direction of the feeding roller 132, with the continuous rotation of the feeding roller 132, the rod 600 will gradually enter the homogenizing shell 110; when the rod 600 completely enters the homogenizing shell 110, the feeding roller 132 will be lowered, so that the supporting surface 1311 of the homogenizing support 131 is in contact with the rod 600, and the supporting surface 1311 of the homogenizing support 131 is used to support the rod 600, and because the supporting surface 1311 of the homogenizing support 131 is a gradually lowered inclined surface from the feeding port 111 to the discharging port, when the feeding roller 132 is lowered to the rod 600 supported by the supporting surface 1311, the rod 600 will be separated from the feeding roller 132 and roll down along the supporting surface 1311 to the discharging roller 133, and the discharging roller 133 receives the rod 600 rolled down from the supporting surface 1311; after the discharging roller 133 receives the rod 600, with the rotation of the discharging roller 133, the rod 600 will be sent out from the discharging port, realizing the flow to the cooling device 200, and at the same time, the vacancy position in the homogenizing furnace 100 will be filled by the next rod 600 entering from the feeding port 111. Wherein, after the rod 600 on the feeding roller 132 can roll down from the supporting surface 1311 of the homogenizing support 131, the feeding roller 132 will rise to receive and flow the next rod 600.

[0041] The setting form of the homogenizing flow assembly 130 can realize the flow of the rod 600 from the feeding port 111 to the inside of the homogenizing furnace 100 and from the inside of the homogenizing furnace 100 to the cooling device 200, and the flow is reliable.

[0042] Please continue to refer to Figure 2 and Figure 3 In the embodiment, the number of the feeding rollers 132 is multiple, and the multiple feeding rollers 132 are arranged along the length direction of the rod 600 in the homogenizing shell 110, which can realize the effective support of the rod 600 in the feeding process and ensure the stability of the rod 600 in the feeding process. Similarly, the number of the discharging rollers 133 is also multiple, and the multiple discharging rollers 133 are arranged along the length direction of the rod 600 in the homogenizing shell 110, which can realize the effective support of the rod 600 in the discharging process and ensure the stability of the rod 600 in the discharging process.

[0043] Please continue to refer to Figure 2 and Figure 3In the embodiment, the homogeneous support 131 can include a plurality of legs, the plurality of legs are arranged at intervals along the conveying direction of the feeding roller 132, and a mounting space is formed between any two adjacent legs. The feeding roller 132 is movably mounted in the mounting space. This arrangement makes the feeding roller 132 not interfere with the homogeneous support 131 when the feeding roller 132 is lowered, so that the bar 600 located on the feeding roller 132 can reliably contact the support surface 1311 of the homogeneous support 131 after the feeding roller 132 is lowered.

[0044] In the embodiment, the up-down movement of the feeding roller 132 can be realized by a linear driving element such as an electric push rod or a pneumatic cylinder.

[0045] Please continue to refer to Figure 2 and Figure 3 In the embodiment, the homogeneous support 131 movably mounts a blocking piece 134. Specifically, the blocking piece 134 is located at the lower end of the support surface 1311. The blocking piece 134 has a blocking position and a release position. In the blocking position, the blocking piece 134 protrudes from the support surface 1311, which is used to limit the bar 600 in the homogeneous support 131 from rolling off to the discharging roller 133. In the release position, the blocking piece 134 is not higher than the support surface 1311.

[0046] During the homogeneous heating of the bar 600, the blocking piece 134 is in the blocking position to prevent the bar 600 in the homogeneous support 131 from rolling off to the discharging roller 133, so as to avoid the bar 600 that has not completed the homogeneous heating from flowing to the cooling device 200. After the homogeneous heating of the bar 600 is completed, the blocking piece 134 is switched to the release position, so that the bar 600 in the homogeneous support 131 can roll off to the discharging roller 133 under the action of gravity, and then be sent to the cooling device 200 by the discharging roller 133.

[0047] Please continue to refer to Figure 3 In the embodiment, the blocking piece 134 can be rotatably mounted on the homogeneous support 131, and the rotation process can be realized by a motor. By controlling the forward and reverse rotation of the motor shaft, the switching of the blocking piece 134 between the blocking position and the release position can be realized.

[0048] Please continue to refer to Figure 1 In the embodiment, the heating device 120 is mounted on the top wall of the homogeneous housing 110. This arrangement is conducive to achieving sufficient heating of the homogeneous housing 110.

[0049] Figure 4 The internal structure of the bar homogeneous heating equipment provided in the embodiment is partially shown Figure 1 Please continue to refer to Figure 2 and Figure 4 , and combine Figure 2In the embodiment, the cooling device 200 can include a cooling support 210, a cooling shell 220, a cooling flow transfer assembly 230, and a cooling element 240. Specifically, the cooling shell 220 is fixedly connected with the cooling support 210 to form a cooling chamber. The cooling shell 220 is provided with a cooling inlet communicated with the discharge port and a cooling outlet for outputting the bar 600 in the cooling chamber. The cooling flow transfer assembly 230 is arranged in the cooling chamber and used for conveying the bar 600 entering the cooling inlet to the cooling outlet and then to the hot saw shearing device 300. The cooling element 240 is arranged in the cooling chamber and used for cooling the bar 600 entering the cooling chamber.

[0050] After the homogenization treatment of the bar 600 is completed by the homogenizing furnace 100, the discharge roller 133 of the homogenizing furnace 100 sends the bar 600 out, so that the bar 600 enters the cooling inlet of the cooling shell 220. After the bar 600 enters the cooling shell 220, the bar 600 is transferred to the cooling flow transfer assembly 230, supported by the cooling flow transfer assembly 230, and cooled by the cooling element 240 to the processing temperature. Then, the bar 600 is transferred from the cooling inlet to the cooling outlet by the cooling flow transfer assembly 230, so that the cooled bar 600 is sent to the hot saw shearing device 300 by the cooling outlet.

[0051] The cooling device 200 is arranged in this way, which effectively connects the homogenizing furnace 100 and the hot saw shearing device 300, so as to achieve the online cooling of the bar 600.

[0052] In the embodiment, the cooling flow transfer assembly 230 is also in the form of a roller, and its structure and conveying principle are similar to those of the feeding roller 132 and the discharge roller 133 in the homogenizing furnace 100, which will not be described herein again.

[0053] Please continue to refer to Figure 4 and Figure 5 In the embodiment, the cooling element 240 can include a plurality of water-cooled nozzles 241 installed on the cooling support 210. The cooling chamber is also provided with a temperature detection element. The temperature detection element is used for detecting the temperature of the cooling chamber. The temperature detection element and the plurality of water-cooled nozzles 241 are electrically connected with the controller of the bar homogenizing and heating equipment.

[0054] When the bar 600 needs to be cooled, the water cooling nozzle 241 can be opened, and the cooling liquid sprayed by the water cooling nozzle 241 is used to cool the bar 600, so as to cool the bar 600 to the processing temperature. In the above process, the temperature detection element detects the temperature of the cooling chamber in real time, and outputs the detected temperature signal to the controller of the bar homogenization heating equipment. The controller controls the action amount and action time of the water cooling nozzle 241 according to the current temperature of the cooling chamber, so as to achieve the purpose of temperature monitoring of the bar 600 and the purpose of temperature control.

[0055] The cooling element 240 is arranged in the above manner, which not only can realize the cooling process of the bar 600, but also can control the cooling speed through the feedback of the temperature detection element and improve the cooling precision.

[0056] It should be noted that, in the present embodiment, how the temperature detection element outputs the detected temperature signal to the controller of the bar homogenization heating equipment, and how the controller controls the action amount and action time of the water cooling nozzle 241 can be obtained by those skilled in the art according to the prior art. The present embodiment does not improve this, and thus will not be described here.

[0057] In the present embodiment, the temperature detection element can be an infrared temperature sensor.

[0058] Figure 4 The connection schematic diagram of the hot saw shearing device 300, the conveying device 400 and the holding furnace 500 of the bar homogenization heating equipment provided in the present embodiment is shown in FIG. 4. Please continue to refer to FIG. 4, Figure 5 and combine with Figure 4In the embodiment, the hot saw shearing device 300 comprises a saw shearing support 310, a saw bed 320, an automatic saw 330 and a saw shearing transfer assembly 340. Specifically, the saw bed 320 is installed on the saw shearing support 310, the saw shearing transfer assembly 340 is arranged between the cooling device 200 and the saw bed 320, and the saw shearing transfer assembly 340 is used to deliver the bar 600 output from the cooling outlet of the cooling device 200 to the saw bed 320. The automatic saw 330 is located between the saw shearing transfer assembly 340 and the saw bed 320, and the automatic saw 330 is used to cut off the bar 600. The saw bed 320 has an inclined bearing surface 321, and the height of the bearing surface 321 gradually decreases along the transfer direction of the bar 600 from the hot saw shearing device 300 to the conveying device 400. The bearing surface 321 is installed with a length-limiting element 322 and a limiting element 323. The length-limiting element 322 is used to limit the cutting length of the bar 600. Along the inclined direction of the bearing surface 321, the limiting element 323 is opposite to and spaced from the length-limiting element 322. The limiting element 323 has a limiting position and a delivery position. In the limiting position, the limiting element 323 protrudes from the bearing surface 321, and the limiting element 323 and the length-limiting element 322 form an accommodation space for accommodating the bar 600 cut to a fixed length. In the delivery position, the limiting element 323 is not higher than the bearing surface 321.

[0059] After the cooling device 200 completes the cooling process of the bar 600, the cooling transfer assembly 230 outputs the bar 600 to the hot saw shearing device 300, and the saw shearing transfer assembly 340 of the hot saw shearing device 300 delivers the bar 600 to the saw bed 320. The length-limiting element 322 arranged on the saw bed 320 is used to limit the length of the bar 600, and the limiting element 323 arranged on the saw bed 320 is in the limiting position protruding from the bearing surface 321. When the length of the bar 600 is determined, the automatic saw 330 works to cut off the bar 600, and at this time, the bar 600 is in the accommodation space formed by the length-limiting element 322 and the limiting element 323. Then, the limiting element 323 can be switched to the delivery position so that the limiting element 323 is not higher than the bearing surface 321, so that the bar 600 in the fixed length in the accommodation space can roll down to the conveying device 400 along the bearing inclined surface of the saw bed 320 under the action of its own gravity, and the transfer of the bar 600 to the conveying device 400 is completed.

[0060] The arrangement of the hot saw shearing device 300 can achieve the purpose of cutting off the bar 600 and the transfer of the bar 600 to the conveying device 400, realize the connection of the hot saw shearing device 300 and the conveying device 400, and ensure the continuity between the processes of the bar homogenizing heating equipment.

[0061] In the embodiment, the number of the limiting elements 323 can be multiple, and the multiple limiting elements 323 are arranged along the length direction of the bar 600 in the accommodating space. The arrangement can increase the reliability of limiting the bar 600, and avoid the bar 600 from being separated from the sawing machine 320 due to deflection.

[0062] In the embodiment, multiple accommodating cavities can be formed in the bearing surface 321 of the sawing machine 320, and the multiple limiting elements 323 are respectively arranged in the multiple accommodating cavities, so as to achieve the switching of the multiple limiting elements 323 between the limiting position and the conveying position.

[0063] Please continue to refer to Figure 5 and Figure 5 In the embodiment, the fixed-length element 322 can achieve the fixed-length processing of the bar 600 by mechanical limiting. Specifically, the fixed-length element 322 is abutted with the end of the bar 600 to limit the length of the bar 600, so as to achieve the fixed-length processing of the bar 600.

[0064] Please continue to refer to Figure 1 In the embodiment, the fixed-length element 322 can be arranged as a movable type, and the moving direction of the fixed-length element 322 is along the length direction of the bar 600 in the accommodating space. Through the arrangement, the position of the fixed-length element 322 can be quickly adjusted, so as to meet the cutting requirement of the bar 600 with different lengths.

[0065] Please continue to refer to Figure 6 In the embodiment, the hot saw shearing device 300 can further include a sawing shell 350, wherein the sawing shell 350 is fixedly connected with the sawing support 310, and the sawing machine 320, the automatic saw 330 and the sawing flow assembly 340 are accommodated in the space formed by the sawing shell 350 and the sawing support 310. Through the arrangement, on the one hand, the unnecessary heat loss of the bar 600 can be reduced to ensure the processing temperature of the bar 600, and on the other hand, the pollution to the surrounding environment caused by the splashing of sawdust can be prevented.

[0066] Figure 2 Partial structure of the bar homogenizing heating equipment provided in the embodiment Figure 5 Please continue to refer to Figure 6 and combine Figure 5In the embodiment, the conveying device 400 comprises a first conveying assembly 410, a second conveying assembly 420 and a rod receiving rack 430 arranged in sequence along the direction of the rod 600, and the holding furnace 500 is arranged beside the second conveying assembly 420. The holding furnace 500 comprises a holding support 510, a holding shell 520, an inlet track 530 and an outlet track 540. The holding shell 520 is connected with the holding support 510 to form a holding chamber. The holding shell 520 is provided with an inlet opening 521 and an outlet opening 522. The inlet track 530 extends from the holding chamber to the inlet opening 521 and is arranged between the first conveying assembly 410 and the second conveying assembly 420. The outlet track 540 extends from the holding chamber to the outlet opening 522 and is connected with the end of the second conveying assembly 420. The inlet track 530 is movably provided with a transition rack 550. The transition rack 550 has a flowing position and a temporary storage position. In the flowing position, the transition rack 550 is arranged between the first conveying assembly 410 and the second conveying assembly 420, and is used for conveying the rod 600 from the first conveying assembly 410 to the second conveying assembly 420. In the temporary storage position, the transition rack 550 is arranged in the holding chamber, and is used for conveying the rod 600 to the holding support 510. The outlet track 540 is movably provided with an outlet rack 560 and a feeding rack 570. The feeding rack 570 is used for conveying the rod 600 from the second conveying assembly 420 to the rod receiving rack 430. The outlet rack 560 is used for receiving the rod 600 from the holding support 510 and conveying the rod 600 to the rod receiving rack 430 when the outlet rack 560 moves to the end of the second conveying assembly 420. The rod receiving rack 430 is used for conveying the received rod 600 to a processing machine.

[0067] When the hot saw shearing device 300 completes the sawing operation on the rod 600, the rod 600 in a fixed length will first enter the first conveying assembly 410 of the conveying device 400 and flow under the action of the first conveying assembly 410. When the rod 600 needs to be processed, the transition rack 550 moves along the inlet track 530 to the position between the first conveying assembly 410 and the second conveying assembly 420. At this time, the transition rack 550 is in the flowing position, so that the rod 600 in the first conveying assembly 410 can flow to the second conveying assembly 420 through the transition rack 550. Then, the rod 600 continues to flow forward under the action of the second conveying assembly 420, and is transferred to the rod receiving rack 430 through the feeding rack 570, so as to achieve the conveying purpose of the rod 600 to the processing machine.

[0068] When the rod 600 output by the hot saw shearing device 300 does not need to be processed, after the rod 600 transferred by the first conveying assembly 410 is received by the transition rack 550, the transition rack 550 is switched from the transfer position to the temporary storage position, and the rod 600 is delivered to the heat preservation support 510, and the rod 600 is heat preserved by the heat preservation furnace 500. When the rod 600 in the heat preservation furnace 500 needs to be processed, the rod 600 in the heat preservation support 510 is received by the furnace outlet rack 560, and the furnace outlet rack 560 moves on the furnace outlet track 540 to the end of the second conveying assembly 420 with the received rod 600, and is connected with the rod receiving rack 430, so as to complete the transfer of the rod 600 from the heat preservation furnace 500 to the rod receiving rack 430. Before the furnace outlet rack 560 drives the rod 600 to move to the end of the second conveying assembly 420, the feeding rack 570 moves away from the heat preservation furnace 500 along the furnace outlet track 540 to avoid the furnace outlet rack 560, so as to prevent the furnace outlet rack 560 from colliding with the feeding rack 570 during the movement of the rod 600.

[0069] The layout of the hot saw shearing device 300, the conveying device 400 and the heat preservation furnace 500 not only realizes reliable transfer of the rod 600 to be processed to the processing machine, but also realizes heat preservation of the rod 600 which is not processed temporarily, thereby increasing the functionality of the rod homogenizing heating equipment.

[0070] Please continue to refer to Figure 6 and Figure 5 In the embodiment, the transition surface 551 of the transition rack 550 is inclined, wherein the height of the transition surface 551 gradually decreases along the transfer direction of the rod 600 from the first conveying assembly 410 to the second conveying assembly 420, that is, the end of the transition surface 551 close to the first conveying assembly 410 is the higher end, and the end of the transition surface 551 close to the second conveying assembly 420 is the lower end. Further, the transition rack 550 is provided with a transition limiting piece 552, which is rotationally arranged on the transition surface 551, and the transition limiting piece 552 has a first position protruding from the transition surface 551 and a second position not higher than the transition surface 551.

[0071] When the bar 600 of the primary conveying assembly 410 needs to be conveyed to the secondary conveying assembly 420, the transition rack 550 is located between the primary conveying assembly 410 and the secondary conveying assembly 420, and the transition limiting piece 552 is in the second position not higher than the transition surface 551, so that the bar 600 output by the primary conveying assembly 410 rolls along the transition surface 551 under the action of gravity and is transferred to the secondary conveying assembly 420. When the bar 600 of the primary conveying assembly 410 needs to be conveyed into the holding furnace 500, the transition rack 550 is first located between the primary conveying assembly 410 and the secondary conveying assembly 420, and the transition limiting piece 552 is switched to the first position protruding from the transition surface 551, so that the bar 600 output by the primary conveying assembly 410 abuts against the transition limiting piece 552 under the action of gravity; then, with the movement of the transition rack 550 on the furnace entry track 530, the bar 600 on the transition rack 550 is conveyed into the holding support 510 in the holding furnace 500 through the furnace entry opening 521, achieving the purpose of temporary storage of the bar 600; after the temporary storage of the bar 600 is completed, the empty transition rack 550 moves from the furnace entry opening 521 to between the primary conveying assembly 410 and the secondary conveying assembly 420, waiting for the next bar 600 transfer or temporary storage operation.

[0072] In this embodiment, the primary conveying assembly 410 and the secondary conveying assembly 420 can both be belt conveying assemblies.

[0073] In this embodiment, the transition limiting piece 552 can be swingably arranged on the transition surface 551. When the transition limiting piece 552 swings upward, the transition limiting piece 552 can be switched to the first position; when the transition limiting piece 552 swings downward, the transition limiting piece 552 can be switched to the second position. The swinging of the transition limiting piece 552 can be achieved by driving of a motor.

[0074] Please continue to refer to Figure 6 and Figure 6 In this embodiment, the feeding rack 570 is provided with a feeding slope, and the height of the feeding slope gradually decreases along the transfer direction of the bar 600 from the primary conveying assembly 410 to the secondary conveying assembly 420. This arrangement enables the bar 600 to roll along the feeding slope under the action of gravity when the bar 600 moves to the end of the secondary conveying assembly 420.

[0075] Please continue to refer to Figure 6 In this embodiment, the holding support 510 is fixedly provided with a plurality of partitions 580, which are arranged in a direction perpendicular to the transfer direction of the bar 600 in the conveying device 400, and each pair of adjacent partitions 580 forms a temporary storage passage 590 for temporarily storing the bar 600.

[0076] Through the above arrangement, on the one hand, the capacity of the holding furnace 500 can be increased to realize the temporary storage of multiple rods 600, and on the other hand, the rods can be separated as much as possible to ensure the internal order of the holding furnace 500 and facilitate the orderly flow of the rods 600.

[0077] Please continue to refer to Figure 5 In the embodiment, the bearing surface of each temporary storage channel 590 is inclined, specifically, the bearing surface of the temporary storage channel 590 gradually decreases from the direction of the furnace entry track 530 to the furnace exit track 540; and the end of each temporary storage channel 590 close to the furnace exit track 540 is provided with an exit baffle 591, wherein the exit baffle 591 has a third position protruding from the bearing surface of the temporary storage channel 590, and a fourth position not higher than the bearing surface of the temporary storage channel 590.

[0078] When the rods 600 are temporarily stored by the holding bracket 510, the exit baffle 591 will be in the third position protruding from the bearing surface of the temporary storage channel 590, and the rods 600 will abut against the exit baffle 591 under the action of their own gravity, so that the rolling of the rods 600 is limited by the exit baffle 591 to prevent the rods 600 from rolling off from the end of the temporary storage channel 590 close to the furnace exit track 540; when the rods 600 temporarily stored in the holding bracket 510 need to be processed, the exit rack 560 will first move to a position corresponding to the temporary storage channel 590 where the rods 600 are stored, then the exit baffle 591 is switched to the fourth position not higher than the bearing surface of the temporary storage channel 590, so that the rods 600 in the temporary storage channel 590 can roll to the exit rack 560 under the action of their own gravity, and be received by the exit rack 560; after the exit rack 560 completes the reception of the rods 600, the exit rack 560 will be output from the exit opening 522 along the furnace exit track 540 and moved to the end of the secondary conveying assembly 420 to be opposite to the rod receiving bracket 430, then the rods 600 are transferred to the rod receiving bracket 430 by rotating the exit rack 560.

[0079] The out-of-furnace rack 560 is a bent plate structure, which includes a first plate body and a second plate body connected at an obtuse angle. When the bar 600 needs to be received in the temporary storage channel 590, the first plate body is connected to the end of the temporary storage channel 590, and the second plate body forms a baffle to prevent the bar 600 from rolling off the out-of-furnace rack 560 due to inertia. When the bar 600 in the out-of-furnace rack 560 needs to be transferred to the bar receiving rack 430, the out-of-furnace rack 560 is rotated relative to the out-of-furnace track 540. At this time, the first plate body is separated from the out-of-furnace track 540, the second plate body forms a transfer plate connecting the out-of-furnace rack 560 and the bar receiving rack 430, and the second plate body is in an inclined state, so that the bar 600 in the out-of-furnace rack 560 can roll along the second plate body to the bar receiving rack 430, completing the transfer of the bar 600 from the out-of-furnace rack 560 to the bar receiving rack 430.

[0080] Please continue to refer to Figure 6 and ​ In this embodiment, the bar receiving rack 430 is movably arranged along the flow direction of the bar 600 in the conveying device 400. When the bar receiving rack 430 needs to receive the bar 600, the bar receiving rack 430 moves towards the conveying device 400, and when the received bar 600 needs to be sent out, the bar receiving rack 430 moves away from the conveying device 400. Through this arrangement, while achieving the transfer of the bar 600 to the processing machine, the size of the bar receiving rack 430 can be reduced, thereby reducing the manufacturing cost of the bar receiving rack 430.

[0081] It should be noted that in this embodiment, the structure of the bar receiving rack 430 for supporting the bar 600 is similar to that of the out-of-furnace rack 560, and the bar receiving rack 430 can also be flipped. When the bar receiving rack 430 needs to transfer the bar 600 supported thereby to the processing machine, the bar receiving rack 430 can be flipped to make the bar 600 roll to the processing machine under the action of gravity.

[0082] It should be further noted that in this embodiment, during the operation of the bar homogenization heating equipment, under normal working conditions, the bar 600 output by the hot saw shearing device 300 can be directly used for processing production, and when there is an abnormal working condition in the production line, the bar 600 output by the hot saw shearing device 300 can be temporarily stored in the holding furnace 500.

[0083] As can be seen from the above, the present application effectively combines the homogenization process of the bar 600 with each process operation before the bar 600 is put on line for production, realizes the unity of each process, facilitates operation and monitoring of the production line state, reduces transportation time and cost, and also reduces energy loss caused by repeated heating. The present application has simple design and wide application prospect.
