Description

Technical Field

[0001] This invention relates to the technical field of metal bar processing systems, and more specifically to an automatic heating and shearing system for metal bars. Background Technology

[0002] In the valve body manufacturing process, metal bars of a certain length are required. These bars are forged using forging equipment to form valve body blanks. Currently, obtaining these metal bars involves shearing a single, continuous metal bar. The process of shearing a single metal bar to the required length involves first heating the bar in a furnace, then transferring it to a shearing device. After shearing, the heated metal bar is cut to the desired length. The metal bar is used for the production of valve body blanks; however, in the above process, the heating and shearing of the entire metal bar need to be completed by different equipment. That is, the entire metal bar after being heated in the heating furnace needs to be manually transferred to the shearing equipment for shearing, which has the disadvantages of high labor costs and low metal bar shearing efficiency. Moreover, there are significant safety hazards during the transfer of the entire heated metal bar. In addition, the metal bar will cool down during the transfer process, which makes it difficult for the subsequent shearing equipment to shear the entire metal bar. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an automatic heating and shearing system for metal bars, which can heat and shear the entire metal bar without the need to transfer the heated metal bar. This reduces labor costs, improves the shearing efficiency of the metal bar, and eliminates the safety hazards that may exist during the transfer of the heated metal bar.

[0004] The automatic heating and shearing system for metal bars of the present invention includes a heating furnace body, a pushing mechanism, a pushing mechanism, and a shearing mechanism; the pushing mechanism is connected to the front side of the heating furnace body and is used to push the metal bars one by one from front to back onto the furnace bed of the heating furnace body; a discharge port is provided on the left side of the heating furnace body and located at the rear of the furnace bed; the pushing mechanism is connected to the heating furnace body located above the furnace bed and is used to push the metal bars located on the furnace bed from right to left so that the metal bars gradually extend out of the furnace bed through the discharge port; the shearing mechanism is connected to the heating furnace body located to the left of the discharge port and is used to shear the metal bars from the discharge port into segmented structures.

[0005] By employing the aforementioned structure, this invention firstly pushes the metal bars one by one from front to back onto the furnace bed of the heating furnace. After the metal bars are pushed onto the furnace bed, the heating furnace heats the metal bars located on the furnace bed. Then, the pushing mechanism pushes the metal bars located on the furnace bed from right to left so that the metal bars gradually extend out of the furnace bed through the discharge port. Then, the shearing mechanism cuts the metal bars from the discharge port into segmented structures. Through the above process, this invention can achieve heating and shearing of the entire metal bar without the need to transfer the heated metal bars, thereby reducing labor costs, improving the shearing efficiency of the metal bars, and eliminating the safety hazards that exist during the transfer of heated metal bars. In addition, after the metal bars are heated, the shearing mechanism can immediately perform a front cut on the metal bars to avoid cooling, thus facilitating the shearing of the metal bars.

[0006] The automatic heating and shearing system for metal bars of the present invention includes a pushing mechanism comprising a driving component and a plurality of supports spaced apart from left to right. Each support is fixed to the front side of the heating furnace body. A pushing frame is slidably connected to the upper end of each support. The driving component is connected to the heating furnace body and synchronously drives each pushing frame to slide back and forth relative to the corresponding support. The upper surface of each pushing frame gradually slopes downward from front to back, and a blocking component is connected to the front end of each pushing frame. When the driving component synchronously drives all pushing frames to slide backward, all pushing frames simultaneously push the metal bars on the furnace bed to roll them to the rear side of the furnace bed. At this time, the blocking components at the front end of each pushing frame block the next metal bar from the metal bar supply device to prevent the metal bar from rolling off the pushing frame onto the furnace bed. When the driving component synchronously drives all pushing frames to slide forward and reset, all blocking components are released. The mechanism blocks the next metal bar, causing it to roll onto the furnace bed via the pusher. With this pushing mechanism, when the drive assembly synchronously drives all pushers to slide backward, all pushers simultaneously push the metal bars on the furnace bed, causing them to roll to the rear side of the furnace bed. This means the metal bars on the furnace bed can abut against the rear inner wall of the furnace bed. At this time, the baffle assembly at the front end of each pusher blocks the next metal bar from the metal bar supply device to prevent it from rolling onto the furnace bed via the pusher. When the drive assembly synchronously drives all pushers to slide forward and reset, all baffle assemblies release the blockage of the next metal bar, allowing it to roll onto the furnace bed via the pusher. This allows the metal bars from the metal bar supply device to be supplied to the furnace bed one by one. Furthermore, the metal bar supply device also supplies metal bars one by one to the automatic heating and shearing system.

[0007] The automatic heating and shearing system for metal bars of the present invention includes a "V"-shaped baffle assembly. The front end of each baffle is rotatably connected to one side of the front end of a corresponding pusher. A roller is rotatably connected to one side of the lower end of each baffle. Each roller is supported on the upper end of a corresponding support. A "V"-shaped slot is provided at the top of the front end of each support. When the drive assembly synchronously drives all pushers to slide backward, each roller rolls to the upper edge of the corresponding support so that the rear end of the baffle is higher than the upper surface of the corresponding pusher and abuts against the next metal bar from the metal bar supply device. When the drive assembly synchronously drives all pushers to slide forward, each roller rolls into the slot on the corresponding support so that the rear end of each baffle is lower than the upper surface of the corresponding pusher and releases the obstruction of the metal bar from the metal bar supply device. By employing this baffle assembly, when the drive assembly synchronously drives all pushers to slide backward… At this time, each roller can roll to the upper edge of the corresponding support so that the rear end of the baffle is higher than the upper end of the pusher at the corresponding position and abuts against the next metal bar from the metal bar supply device. At this time, the baffle component at the front end of each pusher can block the next metal bar from the metal bar supply device to prevent the metal bar from rolling down onto the furnace bed. When the drive component synchronously drives all pushers to slide forward, each roller can roll into the slot on the corresponding support so that the rear end of each baffle is lower than the upper end of the pusher at the corresponding position and releases the obstruction of the metal bar from the metal bar supply device. At this time, the next metal bar from the metal bar supply device can be supplied to the furnace bed. Since the upper end of each pusher gradually slopes downward from front to back, after the baffle component releases the obstruction of the metal bar from the metal bar supply device, the metal bar from the metal bar supply device can roll down onto the furnace bed via the upper end of each pusher.

[0008] The automatic heating and shearing system for metal bars of the present invention includes a driving assembly comprising a first servo motor and a transmission shaft. The first servo motor is fixed to the heating furnace body, and the transmission shaft is rotatably mounted in all supports from left to right. The transmission shaft is connected to the drive end of the first servo motor via a chain assembly. Each pusher has a first rack extending from front to back fixed at its lower end. A first gear corresponding to each first rack is sleeved on the transmission shaft. Each first gear is fixed to the transmission shaft and meshes with the first rack at its corresponding position. By using this driving assembly, when the first servo motor drives the transmission shaft to rotate back and forth via the chain assembly, the cooperation of the first gear and the first rack reliably and synchronously drives each pusher to slide back and forth relative to the support at its corresponding position.

[0009] The automatic heating and shearing system for metal bars of the present invention includes a pushing mechanism comprising a pushing block and a driving component. The pushing block is slidably connected to a heating furnace body located above the furnace bed. The driving component is connected to the heating furnace body and is used to drive the pushing block to slide left and right relative to the heating furnace body. The pushing block and the driving component are connected in a transmission manner. When the driving component drives the pushing block to slide from right to left, the pushing block pushes the metal bar located on the furnace bed from right to left so that the metal bar gradually extends out of the furnace bed through the discharge port. By adopting this pushing mechanism, when the driving component drives the pushing block to slide from right to left, the pushing block can push the metal bar located on the furnace bed from right to left so that the metal bar gradually extends out of the furnace bed through the discharge port. When the driving component drives the pushing block to slide from left to right, the pushing block can slide back to the right.

[0010] The automatic heating and shearing system for metal bars of the present invention includes a driving component comprising a second servo motor, a driving gear, a driven gear, and a chain. The second servo motor is fixed to one end of the heating furnace body, the driving gear is fixed to the output shaft of the second servo motor, and the driven gear is rotatably connected to the other end of the heating furnace body. The chain is sleeved on the driving gear and the driven gear and is connected to them in a transmission manner. The upper end of the pusher block is fixed to the lower edge of the chain. By adopting this driving component, when the second servo motor drives the driving gear to reciprocate, the chain can reciprocate under the cooperation of the chain and the driven gear. Since the upper end of the pusher block is fixed to the lower edge of the chain, and since the pusher block is slidably connected to the heating furnace body located above the furnace bed, the pusher block can slide left and right relative to the heating furnace body.

[0011] The automatic heating and shearing system for metal bars of the present invention includes a shearing mechanism comprising a coaxiality adjustment component and a shearing component. The coaxiality adjustment component is connected to the heating furnace body located on the left side of the discharge port, and the shearing component is connected to the adjustment end of the coaxiality adjustment component. The coaxiality adjustment component is used to adjust the coaxiality between the shearing component and the metal bar from the discharge port, and the shearing component is used to shear the metal bar from the discharge port into segmented structures. By employing this shearing mechanism, since the shearing component is connected to the adjustment end of the coaxiality adjustment component, the coaxiality adjustment component can adjust the coaxiality between the shearing component and the metal bar from the discharge port. That is, when the outer diameter of the metal bar changes, causing the axis of the metal bar to shift, the shearing center of the shearing component can be aligned with the center of the metal bar under the action of the coaxiality adjustment component. This allows the present invention to shear metal bars with different outer diameters, thereby improving the versatility of the present invention. The shearing component is used to shear the metal bar from the discharge port into segmented structures.

[0012] The automatic heating and shearing system for metal bars of the present invention includes a coaxiality adjustment component comprising a base, a first sliding seat, a third servo motor, a second sliding seat, a first servo cylinder, a third sliding seat, and a second servo cylinder. The base is fixed to a heating furnace body located to the left of the discharge port. The first sliding seat is slidably connected to the base. The third servo motor is fixed to the base, and a first transmission gear is fixed to the output shaft of the third servo motor. A second rack is fixed to the lower end of the first sliding seat, and the second rack meshes with the first transmission gear. The third servo motor drives the first sliding seat to move left and right relative to the heating furnace body. The second sliding seat is slidably connected to the first sliding seat. The first servo cylinder is fixed to the first sliding seat. A connecting block is fixed to the inner end face of the second sliding seat. The first sliding seat has a sliding hole for the connecting block to pass through and slide. The driving end of the first servo cylinder is fixed to the connecting block, and the first servo cylinder drives the second sliding seat to move back and forth relative to the heating furnace body. The third sliding seat is slidably connected to the second sliding seat. The second servo cylinder is fixed to the second sliding seat, and the driving end of the second servo cylinder is fixed to the third sliding seat. The second servo cylinder drives the second sliding seat to move forward and backward relative to the heating furnace body. The third sliding seat moves up and down relative to the heating furnace body. The first and second sliding seats are respectively provided with a first channel and a second channel for the metal bar from the discharge port to pass through axially. The shearing assembly is connected to the third sliding seat. By using this coaxiality adjustment assembly, when the third servo motor drives the first transmission gear to rotate reciprocally, the first sliding seat can move left and right relative to the heating furnace body under the cooperation of the first transmission gear and the second rack, thereby adjusting the distance between the shearing assembly and the heating furnace body. When the drive end of the first servo cylinder extends or retracts, the first servo cylinder can drive the second sliding seat to move back and forth relative to the heating furnace body. When the drive end of the second servo cylinder extends or retracts, the second servo cylinder can drive the third sliding seat to move up and down relative to the heating furnace body. Since the second sliding seat is slidably connected to the first sliding seat, the third sliding seat is slidably connected to the second sliding seat, and the shearing assembly is connected to the third sliding seat, the shearing center of the shearing assembly can be aligned with the center of the metal bar. The first and second channels are used for the metal bar from the discharge port to pass through axially to achieve the purpose of avoiding air gaps.

[0013] The automatic heating and shearing system for metal bars of the present invention includes a shearing assembly comprising a guide sleeve, an end plate, a baffle, two sliders, and two fourth servo motors. The guide sleeve is inserted into a third sliding seat and is used for axial passage of the metal bar from the discharge port. The end plate is fixed to the outer end of the third sliding seat and is used to press the guide sleeve onto the third sliding seat. The end plate has a through hole coaxial with the guide sleeve, which is used for axial passage of the metal bar from the discharge port. The two sliders are located on both sides of the guide sleeve and are slidably connected to the third sliding seat. The two fourth servo motors are fixed to the outer end face of the end plate and are respectively arranged corresponding to one of the sliders. The output shafts of the two fourth servo motors are each fixed with a second transmission gear, which meshes with the rack portion on the corresponding slider. The two fourth servo motors are used to drive the two sliders to move closer or further apart. The baffle is fixed to the outer end face of the end plate, and two cutters are slidably connected between the baffle and the end plate. The two cutters are located on both sides of the through hole, and each cutter is fixed to one of the sliders. When the two sliders move closer to each other so that the two cutters move closer to each other, the two cutters cut the metal bar passing through the through hole. With this shearing assembly, under the action of two fourth servo motors, the two fourth servo motors can drive the two sliders to move closer or further apart. When the two sliders move closer to each other so that the two cutters move closer to each other, the two cutters can cut the metal bar passing through the through hole, thereby achieving the purpose of shearing the metal bar into a segmented structure. When the two sliders move further apart so that the two cutters move further apart, the two sliders can drive the two cutters to reset. Through the reciprocating movement of the cutters, continuous shearing of the metal bar can be achieved.

[0014] The automatic heating and shearing system for metal bars of the present invention includes a shearing assembly comprising a rotating frame, a third servo cylinder, and a push rod. The upper edge of one end of the rotating frame is rotatably connected to the outer end face of an end plate located above a through hole, and the lower edge of one end of the rotating frame is supported on the outer end face of the end plate. The third servo cylinder is fixed to the other end of the rotating frame. The push rod is coaxially arranged with the through hole, and its outer end is fixed to the driving end of the third servo cylinder. The inner end of the push rod is used to abut against the end of the metal bar passing through the through hole. The third servo cylinder is used to drive the push rod closer to or away from the through hole. By employing this shearing assembly, the inner end of the push rod can abut against the end of the metal bar passing through the through hole, thereby defining the distance between the through hole and the push rod. The length of the metal bar between the two cutters is such that when the metal bar is cut by the two cutters, it can be cut to the required length. When it is necessary to adjust the length of the cut metal bar, the push rod can be driven by the third servo electric cylinder to move closer to or away from the through hole. At this time, the distance between the push rod and the through hole can be changed, thereby changing the length of the cut metal bar. In addition, since the upper edge of one end of the rotating frame is rotatably connected to the outer end face of the end plate located above the through hole, and the lower edge of one end of the rotating frame is supported on the outer end face of the end plate, when the shearing assembly needs maintenance, the rotating frame, the third servo electric cylinder and the push rod can be flipped upward to avoid obstacles, thus facilitating the maintenance of the shearing assembly.

[0030] like Figure 1-12As shown, the automatic heating and shearing system for metal bars of the present invention includes a heating furnace body 1, a pushing mechanism 3, a pushing mechanism 4, and a shearing mechanism 5. The pushing mechanism 3 is connected to the front side of the heating furnace body 1 and is used to push the metal bars one by one from front to back onto the furnace bed 2 of the heating furnace body 1. A discharge port 11 is provided on the left side of the heating furnace body 1 at the rear of the furnace bed 2. The pushing mechanism 4 is connected to the heating furnace body 1 located above the furnace bed 2 and is used to push the metal bars located on the furnace bed 2 from right to left so that the metal bars gradually extend out of the furnace bed 2 through the discharge port 11. The shearing mechanism 5 is connected to the heating furnace body 1 located to the left of the discharge port 11 and is used to shear the metal bars from the discharge port 11 into segmented structures.

[0031] When the present invention is in operation, the pushing mechanism first pushes the metal bars one by one from front to back onto the furnace bed of the heating furnace body. After the metal bars are pushed onto the furnace bed, the heating furnace body can heat the metal bars located on the furnace bed. Then, the pushing mechanism can push the metal bars located on the furnace bed from right to left so that the metal bars gradually extend out of the furnace bed through the discharge port. Then, the shearing mechanism can shear the metal bars from the discharge port into segmented structures.

[0032] The feeding mechanism 3 includes a drive assembly and several supports 31 spaced apart from left to right. Each support 31 is fixed to the front side of the heating furnace body 1. Each support 31 has a feeding frame 32 slidably connected to its upper end. The drive assembly is connected to the heating furnace body 1 and synchronously drives each feeding frame 32 to slide back and forth relative to the corresponding support 31. The upper surface of each feeding frame 32 gradually slopes downwards from front to back, and a baffle assembly is connected to the front end of each feeding frame 32. When the drive assembly synchronously drives all feeding frames 32 to slide backwards, all feeding frames 32 simultaneously push the metal bars located on the furnace bed 2 to roll them to the rear side of the furnace bed 2. At this time, the baffle assembly at the front end of each feeding frame 32 blocks the next metal bar from the metal bar supply device to prevent the metal bar from rolling off the feeding frame 32 onto the furnace bed 2. When the drive assembly synchronously drives all feeding frames 32 to slide forward and reset, all baffle assemblies... All components release the obstruction of the next metal bar, allowing the metal bar to roll onto the furnace bed 2 via the pusher 32. With this pushing mechanism, when the drive assembly synchronously drives all pushers to slide backward, all pushers simultaneously push the metal bars on the furnace bed, causing them to roll to the rear side of the furnace bed. That is, the metal bars on the furnace bed can abut against the rear inner wall of the furnace bed. At this time, the blocking components at the front end of each pusher can block the next metal bar from the metal bar supply device to prevent it from rolling onto the furnace bed via the pusher. When the drive assembly synchronously drives all pushers to slide forward and reset, all blocking components release the obstruction of the next metal bar, allowing it to roll onto the furnace bed via the pusher. This allows the metal bars from the metal bar supply device to be supplied to the furnace bed one by one. Furthermore, the metal bar supply device also supplies the metal bars one by one to the automatic heating and shearing system.

[0033] Each material stop assembly includes a "V"-shaped material stop frame 33. The front end of each material stop frame 33 is rotatably connected to one side of the front end of a corresponding pusher frame 32. A roller 34 is rotatably connected to one side of the lower end of each material stop frame 33. Each roller 34 is supported on the upper end of a corresponding support 31. The top of the front end of each support 31 is provided with a "V"-shaped slot 311. When the drive assembly synchronously drives all pusher frames 32 to slide backward, each roller 34 is used to roll to the upper edge of the corresponding support 31. The rear end of the baffle 33 is positioned higher than the upper surface of the corresponding pusher 32 and is used to abut against the next metal bar from the metal bar supply device. When the drive assembly synchronously drives all pushers 32 to slide forward, each roller 34 rolls into the slot 311 on the corresponding support 31 so that the rear end of each baffle 33 is lower than the upper surface of the corresponding pusher 32 and releases the obstruction of the metal bar from the metal bar supply device. By adopting this baffle assembly, when the drive assembly synchronously... When all the pushers slide backward, each roller rolls to the upper edge of its corresponding support so that the rear end of the baffle is higher than the upper surface of the pusher at the corresponding position and abuts against the next metal bar from the metal bar supply device. At this time, the baffle assembly at the front end of each pusher blocks the next metal bar from the metal bar supply device to prevent the metal bar from rolling off the pusher onto the furnace bed. When the drive assembly synchronously drives all the pushers to slide forward, each roller rolls to its corresponding support. The groove is designed so that the rear end of each baffle is lower than the upper end of the corresponding pusher and the obstruction of the metal bar from the metal bar supply device is released. At this time, the next metal bar from the metal bar supply device can be supplied to the furnace bed. Since the upper end of each pusher is gradually inclined downward from front to back, after the baffle assembly releases the obstruction of the metal bar from the metal bar supply device, the metal bar from the metal bar supply device can roll down onto the furnace bed through the upper end of each pusher.

[0034] The drive assembly includes a first servo motor 35 and a drive shaft 36. The first servo motor 35 is fixed on the heating furnace body 1. The drive shaft 36 is rotatably inserted through all the supports 31 from left to right. The drive shaft 36 is connected to the drive end of the first servo motor 35 via a chain assembly. Each pusher 32 has a first rack 37 extending from front to back fixed at its lower end. A first gear corresponding to each first rack 37 is sleeved on the drive shaft 36. Each first gear is fixed to the drive shaft 36 and meshes with the first rack 37 at the corresponding position. With this drive assembly, when the first servo motor drives the drive shaft to rotate back and forth via the chain assembly, the first gear and the first rack can reliably and synchronously drive each pusher to slide back and forth relative to the support at the corresponding position under the cooperation of the first gear and the first rack.

[0035] The pushing mechanism 4 includes a pushing block 41 and a driving component. The pushing block 41 is slidably connected to the heating furnace body 1 located above the furnace bed 2. The driving component is connected to the heating furnace body 1 and is used to drive the pushing block 41 to slide left and right relative to the heating furnace body 1. The pushing block 41 is connected to the driving component in a transmission manner. When the driving component drives the pushing block 41 to slide from right to left, the pushing block 41 is used to push the metal bar located on the furnace bed 2 from right to left so that the metal bar gradually extends out of the furnace bed 2 through the discharge port 11. With this pushing mechanism, when the driving component drives the pushing block to slide from right to left, the pushing block can push the metal bar located on the furnace bed from right to left so that the metal bar gradually extends out of the furnace bed through the discharge port. When the driving component drives the pushing block to slide from left to right, the pushing block can slide back to the right.

[0036] The driving component includes a second servo motor 42, a drive gear 43, a driven gear 44, and a chain. The second servo motor 42 is fixed to one end of the heating furnace body 1. The drive gear 43 is fixed to the output shaft of the second servo motor 42. The driven gear 44 is rotatably connected to the other end of the heating furnace body 1. The chain is sleeved on the drive gear 43 and the driven gear 44 and is connected to them in a transmission manner. The upper end of the pusher block 41 is fixed to the lower edge of the chain. With this driving component, when the second servo motor drives the drive gear to rotate reciprocally, the chain can rotate reciprocally under the cooperation of the chain and the driven gear. Since the upper end of the pusher block is fixed to the lower edge of the chain, and since the pusher block can slide left and right on the heating furnace body located above the furnace bed, the pusher block can slide left and right relative to the heating furnace body.

[0037] The shearing mechanism 5 includes a coaxiality adjustment component and a shearing component. The coaxiality adjustment component is connected to the heating furnace body 1 located on the left side of the discharge port 11, and the shearing component is connected to the adjustment end of the coaxiality adjustment component. The coaxiality adjustment component is used to adjust the coaxiality between the shearing component and the metal bar from the discharge port 11, and the shearing component is used to shear the metal bar from the discharge port 11 into segmented structures. By adopting this shearing mechanism, since the shearing component is connected to the adjustment end of the coaxiality adjustment component, the coaxiality adjustment component can adjust the coaxiality between the shearing component and the metal bar from the discharge port. That is, when the outer diameter of the metal bar changes, causing the axis of the metal bar to shift, the shearing center of the shearing component can be aligned with the center of the metal bar under the action of the coaxiality adjustment component. This allows the present invention to shear metal bars with different outer diameters, thereby improving the versatility of the present invention. The shearing component is used to shear the metal bar from the discharge port into segmented structures.

[0038] The coaxiality adjustment assembly includes a base 51, a first sliding seat 52, a third servo motor 53, a second sliding seat 54, a first servo electric cylinder 55, a third sliding seat 56, and a second servo electric cylinder 57. The base 51 is fixed to the heating furnace body 1 located to the left of the discharge port 11. The first sliding seat 52 is slidably connected to the base 51. The third servo motor 53 is fixed to the base 51. A first transmission gear 531 is fixed on the output shaft of the third servo motor 53. A second rack 521 is fixed to the lower end of the first sliding seat 52. The second rack 521 meshes with the first transmission gear 531. The third servo motor 53 is used to drive the first sliding seat. 52 moves left and right relative to the heating furnace body 1; the second sliding seat 54 is slidably connected to the first sliding seat 52, the first servo electric cylinder 55 is fixed to the first sliding seat 52, a connecting block 541 is fixed on the inner end face of the second sliding seat 54, the first sliding seat 52 is provided with a sliding hole 522 for the connecting block 541 to pass through and slide, the driving end of the first servo electric cylinder 55 is fixed to the connecting block 541, and the first servo electric cylinder 55 is used to drive the second sliding seat 54 to move back and forth relative to the heating furnace body 1; the third sliding seat 56 is slidably connected to the second sliding seat 54, the second servo electric cylinder 57 is fixed to the second sliding seat 54, and the second servo electric cylinder... The drive end of 57 is fixed to the third sliding seat 56. The second servo electric cylinder 57 is used to drive the third sliding seat 56 to move up and down relative to the heating furnace body 1. The first sliding seat 52 and the second sliding seat 54 are respectively provided with a first channel 523 and a second channel 542 for the metal bar from the discharge port 11 to pass through axially. The shearing assembly is connected to the third sliding seat 56. By using this coaxiality adjustment assembly, when the third servo motor drives the first transmission gear to rotate reciprocally, under the cooperation of the first transmission gear and the second rack, the first sliding seat can move left and right relative to the heating furnace body, thereby adjusting the shearing assembly and the heating furnace body. The spacing between the furnace bodies; when the drive end of the first servo cylinder extends or retracts, the first servo cylinder can drive the second sliding seat to move back and forth relative to the furnace body; when the drive end of the second servo cylinder extends or retracts, the second servo cylinder can drive the third sliding seat to move up and down relative to the furnace body. Since the second sliding seat is slidably connected to the first sliding seat and the third sliding seat is slidably connected to the second sliding seat, and the shearing assembly is connected to the third sliding seat, the shearing center of the shearing assembly can be aligned with the center of the metal bar; the first channel and the second channel are used for the axial passage of the metal bar from the discharge port to achieve the purpose of avoiding air gaps.

[0039] The shearing assembly includes a guide sleeve 61, an end plate 62, a baffle 63, two sliders 64, and two fourth servo motors 65. The guide sleeve 61 is inserted into the third sliding seat 56 and is used for the axial passage of a metal bar from the discharge port 11. The end plate 62 is fixed to the outer end of the third sliding seat 56 and is used to press the guide sleeve 61 onto the third sliding seat 56. The end plate 62 is provided with a through hole 621 coaxial with the guide sleeve 61, which is used for the axial passage of a metal bar from the discharge port 11. The two sliders 64 are located on both sides of the guide sleeve 61 and are slidably connected to the third sliding seat 56. The two fourth servo motors 65 are fixed on the outer end face of the end plate 62 and are respectively arranged corresponding to one of the sliders 64. The output shafts of the two fourth servo motors 65 are each fixed with a second transmission gear 66, which meshes with the rack portion on the corresponding slider 64. The two fourth servo motors 65 are used to drive the two sliders 64. The sliders 64 move closer or further apart; the baffle 63 is fixed to the outer end face of the end plate 62, and two cutters are slidably connected between the baffle 63 and the end plate 62. The two cutters are located on both sides of the through hole 621, and each cutter is fixed to one of the sliders 64. When the two sliders 64 move closer to each other so that the two cutters move closer to each other, the two cutters are used to cut the metal bar passing through the through hole 621. By using this shearing assembly, under the action of the two fourth servo motors, the two fourth servo motors can drive the two sliders to move closer or further apart. When the two sliders move closer to each other so that the two cutters move closer to each other, the two cutters can cut the metal bar passing through the through hole, thereby achieving the purpose of cutting the metal bar into a segmented structure. When the two sliders move further apart so that the two cutters move further apart, the two sliders can drive the two cutters to reset. Through the reciprocating movement of the cutters, continuous shearing of the metal bar can be achieved.

[0040] The shearing assembly also includes a rotating frame 67, a third servo cylinder 68, and a push rod 69. The upper edge of one end of the rotating frame 67 is rotatably connected to the outer end face of the end plate 62 located above the through hole 621, and the lower edge of one end of the rotating frame 67 is supported on the outer end face of the end plate 62. The third servo cylinder 68 is fixed to the other end of the rotating frame 67. The push rod 69 is coaxially arranged with the through hole 621. The outer end of the push rod 69 is fixed to the driving end of the third servo cylinder 68, and the inner end of the push rod 69 is used to abut against the end of a metal bar passing through the through hole 621. The third servo cylinder 68 is used to drive the push rod 69 closer to or further away from the through hole 621. By using this shearing assembly, the inner end of the push rod can abut against the end of a metal bar passing through the through hole. This allows for the limitation of the length of the metal bar between the through hole and the push rod. When the two cutters shear the metal bar, it can be cut to the required length. When the length of the sheared metal bar needs to be adjusted, the push rod can be driven closer to or further away from the through hole via the third servo electric cylinder. This changes the distance between the push rod and the through hole, thus altering the length of the sheared metal bar. Furthermore, since the upper edge of one end of the rotating frame is rotatably connected to the outer end face of the end plate located above the through hole, and the lower edge of one end of the rotating frame is supported on the outer end face of the end plate, the rotating frame, the third servo electric cylinder, and the push rod can be flipped upwards when the shearing assembly needs maintenance, thus achieving the purpose of avoidance and facilitating the maintenance of the shearing assembly.
