Description

Technical Field

[0001] This invention relates to the field of steel bar processing equipment technology, and in particular to a steel bar processing equipment for use in tunnel construction sites. Background Technology

[0002] In tunnel construction, after the tunnel is excavated, it needs to be reinforced with reinforced concrete structures. During construction, steel bars are combined to form a skeleton, and then concrete is poured to complete the tunnel construction. However, when assembling the steel bars, welding is required, and the steel bars also need to be bent according to the actual use location so that the shape and size of the steel bars can meet the assembly requirements.

[0003] For example, Chinese utility model patent application number CN202020871566.2 discloses a roll welding machine for pre-bending latitudinal steel bars. A horizontal support frame is fixedly connected to the top of the support column of the roll welding machine. An operating table support base is fixedly connected to the top of the left end of the horizontal support frame. A first rotary motor is fixedly connected to the right side of the operating table support base, and a first rotating shaft is fixedly connected to the top of the first rotary motor. This roll welding machine for pre-bending latitudinal steel bars is equipped with a bending arm and a welding machine. When the steel bar needs to be bent, the operator rotates the handle to drive the first gear to rotate. The first gear then drives the bending arm to rotate and move according to the running track, causing the steel bar to bend. After bending, rotating the handle drives the bending arm to reset. The bent steel bar then moves to the roll welding machine, where a second rotary motor drives the inside of the roll welding machine to rotate via a track, welding the bent steel bar. This device meets the needs of different tasks and improves modification costs and work efficiency. And Chinese utility model patent application number CN202020871566.2 describes a platform for fabricating steel reinforcement skeletons for subway tunnel segments. The platform includes a box body. The top outer wall of the box body has a first sliding groove and a second sliding groove distributed in parallel. Two parallel bending rods are arranged at the top of the first sliding groove, and two bending columns of different heights are arranged at the top of the second sliding groove. Threaded rods are welded to the bottom outer walls of both the bending rods and the bending columns, which are perpendicular to the top outer wall of the box body. Two symmetrically distributed support rods are welded to the top outer wall of the box body. This utility model adjusts the relative positions according to the bending angle requirements of the subway tunnel segment steel reinforcement skeleton, facilitating use and adjustment by workers, improving the overall flexibility of the fabrication platform, preventing steel reinforcement displacement, increasing stability during welding, improving welding efficiency and overall welding quality, reducing pollution to the surrounding environment, and improving the working environment.

[0004] In the aforementioned patent, when processing reinforcing bars, the reinforcing bars are bent by the body of a reinforcing bar welding machine, and then welded to meet usage requirements. During bending, the reinforcing bars are placed on a bending disc, and the machine body is activated by pressing a spring-loaded switch, causing the bending disc to rotate. The bending is then achieved through the cooperation of a central bending column and a follow-up bending column. However, during reinforcing bar bending, due to manual or equipment-related reasons, such as manual handling leading to insecure fixing, or insufficient die radius or improper gap between the upper and lower dies (too small increases resistance, too large causes secondary scratches), stress concentration and uneven force can occur. Therefore, under these circumstances, the reinforcing bars are prone to jumping, potentially leading to safety accidents. Summary of the Invention

[0005] The purpose of this invention is to provide a steel bar processing device for tunnel construction sites to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A steel bar processing equipment for tunnel construction sites includes a welding machine body, on which a rotating bending disc, a position adjusting seat, and a switch seat are installed. A central bending column and a follower bending column are installed on the rotating bending disc. A spring-loaded pressing plate is installed on the switch seat, and a hand guard is installed on the switch seat. A welding head is installed on the welding machine body. It also includes a bending anti-jump mechanism, which is installed on the central bending column and the follower bending column.

A snap-fit ​​sleeve is installed on the central bending column. The integrated mounting sleeve is rotatably installed on the snap-fit ​​sleeve. A rotating fastening plate is rotatably installed on the integrated mounting sleeve. A fastening anti-jump cover is installed on the rotating fastening plate. The fastening anti-jump cover is snapped on the follower bending column. A downward pressure slide plate is sleeved on the central bending column and the follower bending column. The downward pressure slide plate is slidably installed on the integrated mounting sleeve. It also includes a rebar isolation and clamping mechanism, which is installed on the welding machine body and is used to isolate and clamp the rebar.

Mounting side seats are installed on both sides of the welding machine body. Synchronous drive columns are rotatably installed on the two mounting side seats. Synchronous drive sleeves are installed on the bottom side of both active isolation plates. The synchronous drive columns are rotatably installed in the two synchronous drive sleeves. The rotation of the synchronous drive columns drives the two synchronous drive sleeves to move, thereby driving the two active isolation plates to move.

[0007] Furthermore, in a preferred embodiment of the present invention, the bending anti-jump mechanism further includes two pull rods, both of which are slidably mounted on the integrated mounting sleeve, and both of which are mounted on the pressing slide plate; Two lifting springs are installed on the downward sliding plate, and both lifting springs are mounted on the integrated mounting sleeve.

[0008] Furthermore, in a preferred embodiment of the present invention, the integrated mounting sleeve has two snap-fit ​​slots, a snap-fit ​​rotating shaft is rotatably installed in the two snap-fit ​​slots, and a pressing rotating plate is installed at both ends of the snap-fit ​​rotating shaft; and a snap-fit ​​pushing frame is installed on the two pull rods. A snap-fit ​​torsion spring is installed on the snap-fit ​​groove, and the snap-fit ​​torsion spring is mounted on the snap-fit ​​shaft.

[0009] Furthermore, in a preferred embodiment of the present invention, a limiting stop strip is installed on the integrated mounting sleeve, the limiting stop strip being used to limit the rotation angle of the rotating fastening plate.

[0010] Furthermore, in a preferred embodiment of the present invention, the rebar isolation clamping mechanism further includes two adaptive clamping tooth plates, which are slidably mounted on the two active isolation plates respectively, and the adaptive clamping tooth plates are used to close the active isolation plates; A locking toothed plate is slidably mounted on the active isolation plate, and the locking toothed plate engages with the adaptive clamping toothed plate.

[0011] Furthermore, in a preferred embodiment of the present invention, a lifting slide groove is provided on the active isolation plate, and the locking tooth plate is slidably mounted on the lifting slide groove; A locking spring is installed on the bottom side of the locking tooth plate, and the locking spring is installed on the bottom inner wall of the lifting slide.

[0012] Furthermore, in a preferred embodiment of the present invention, two limiting rotating rings are sleeved on the synchronous drive column, and the two limiting rotating rings are respectively rotatably installed in the two mounting side seats; Two arc-shaped push slots are provided on the synchronous drive column, and arc-shaped push blocks are installed on the inner walls of the two synchronous drive sleeves. The two arc-shaped push blocks are respectively movably installed in the two arc-shaped push slots.

[0013] Furthermore, in a preferred embodiment of the present invention, a synchronous linkage mechanism is also included. The synchronous linkage mechanism is installed on the switch base, and the bending anti-jump mechanism and the rebar isolation clamping mechanism are both connected to the synchronous linkage mechanism. The synchronous linkage mechanism is used to drive the bending anti-jump mechanism and the rebar isolation clamping mechanism.

[0014] Furthermore, in a preferred embodiment of the present invention, the synchronous linkage mechanism includes an ejection limiting frame, which is slidably mounted on the hand guard and is engaged with the pressing slide plate; Rotary push rods are installed on both sides of the rebound pressing plate, and rotating push shafts are rotatably installed on both of the two rotary push rods. Push grooves are opened on both sides of the ejection limiting frame, and the two rotary push shafts are slidably installed in the two push grooves respectively.

[0015] Furthermore, in a preferred embodiment of the present invention, a mounting plate is installed on one side of the switch base, a downward linkage frame is slidably mounted on the mounting plate, and a gear plate frame is mounted on the downward linkage frame. A gear is installed at one end of the synchronous drive column, and the gear meshes with the gear plate frame. A lifting spring is installed on the downward linkage frame, and the lifting spring is mounted on the mounting plate.

[0016] The beneficial effects of the steel bar processing equipment for tunnel construction sites proposed in this invention are: In this invention, by setting up a bending anti-jump mechanism, when the reinforcing bar is placed between the central bending column and the follower bending column for bending, the reinforcing bar presses down on the lower pressure slide plate. The lower pressure slide plate moves on the central bending column and the follower bending column, and at the same time, the downward movement of the lower pressure slide plate drives the two pull rods to move, thereby causing the rotating fastening plate to drive the fastening anti-jump cover to rotate and fasten onto the follower bending column, thus sealing the reinforcing bar between the rotating fastening plate and the lower pressure slide plate, preventing the reinforcing bar from jumping during bending. In addition, during bending, the rotating bending plate drives the follower bending column to rotate and bend the reinforcing bar. At this time, the fastening anti-jump cover rotates, and the rotation of the fastening anti-jump cover drives the integrated installation sleeve to rotate through the rotating fastening plate, thereby causing the integrated installation sleeve to rotate on the snap-fit ​​sleeve, achieving the purpose of fully restricting the reinforcing bar during bending.

[0017] Furthermore, in this invention, by setting up a rebar isolation clamping mechanism, when the synchronous drive column rotates, it drives two active isolation plates to move and close, thereby clamping the rebar and isolating the welding machine body from the operator to avoid accidents. In addition, by restricting the rebar with two adaptive clamping tooth plates, the problem of the rebar jumping during bending is further avoided, ensuring the safety of the rebar bending operation.

[0018] Furthermore, in this invention, by setting up a synchronous linkage mechanism, when bending, pressing the spring-loaded pressing plate causes it to rotate on the switch base. Simultaneously, the rotation of the spring-loaded pressing plate drives two rotating push rods to rotate, which in turn drive the push rods to move the ejector restraint frame via the rotating push shaft. When the ejector restraint frame moves, it locks onto the lower pressing slide plate. This allows the lower pressing slide plate to be restricted when the spring-loaded pressing plate is pressed for bending, ensuring that the reinforcing bar can be continuously restrained. At the same time, when the spring-loaded pressing plate is pressed, it compresses the lower pressing linkage frame to move. The movement of the lower pressing linkage frame causes the rising spring to be stretched, and the movement of the lower pressing linkage frame causes the toothed plate frame to move, causing the toothed plate frame to drive the gear to rotate. The rotation of the gear drives the synchronous drive column to rotate, thereby achieving sufficient restraint of the reinforcing bar when the spring-loaded pressing plate is pressed.

[0027] Please refer to the attached instruction manual. Figures 1-11 The present invention provides a steel bar processing equipment for tunnel construction sites, which includes a welding machine body 1, a rotating bending disc 2, a position adjusting seat 3 and a switch seat 10 installed on the welding machine body 1, a central bending column 4 and a follower bending column 5 installed on the rotating bending disc 2, a spring-loaded pressing plate 6 installed on the switch seat 10, and a hand guard 11 installed on the switch seat 10, and a welding head 12 installed on the welding machine body 1.

[0028] Further, please refer to the appendix to the instruction manual. Figures 2-4 The present invention provides a steel bar processing equipment for tunnel construction sites, which further includes a bending anti-jump mechanism 7. The bending anti-jump mechanism 7 is installed on a central bending column 4 and a follower bending column 5, and is used to close the gap between the central bending column 4 and the follower bending column 5. Specifically, the bending anti-jump mechanism 7 includes an integrated mounting sleeve 701, a snap-fit ​​sleeve 704 is installed on the central bending column 4, the integrated mounting sleeve 701 is rotatably installed on the snap-fit ​​sleeve 704, a rotating fastening plate 703 is rotatably installed on the integrated mounting sleeve 701, a fastening anti-jump cover 702 is installed on the rotating fastening plate 703, the fastening anti-jump cover 702 is snapped on the follower bending column 5, and a downward pressure slide plate 705 is sleeved on the central bending column 4 and the follower bending column 5, and the downward pressure slide plate 705 is slidably installed on the integrated mounting sleeve 701.

[0029] It should be noted that in this embodiment of the invention, when the reinforcing bar is placed between the central bending column 4 and the follower bending column 5 for bending, the reinforcing bar presses down on the lower pressure slide plate 705 and moves downward, thereby causing the rotating fastening plate 703 to drive the fastening anti-jump cover 702 to rotate and fasten onto the follower bending column 5, thus enclosing the reinforcing bar between the rotating fastening plate 703 and the lower pressure slide plate 705, preventing the reinforcing bar from jumping during bending; in addition, during bending, the rotating bending disc 2 drives the follower bending column 5 to rotate and bend the reinforcing bar, which in turn drives the fastening anti-jump cover 702 to rotate. The rotation of the fastening anti-jump cover 702 drives the integrated mounting sleeve 701 to rotate through the rotating fastening plate 703, so that the integrated mounting sleeve 701 rotates on the snap-fit ​​sleeve 704, thereby achieving the purpose of fully restricting the reinforcing bar during bending.

[0030] More specifically, in this embodiment of the invention, a rebar isolation and clamping mechanism 8 is also included. The rebar isolation and clamping mechanism 8 is installed on the welding machine body 1 and is used to isolate and clamp the rebar. The rebar isolation and clamping mechanism 8 includes two active isolation plates 801. A transverse sliding groove 809 is provided on one side of the welding machine body 1. Both active isolation plates 801 are slidably installed in the transverse sliding groove 809. A rebar movable groove 802 is provided on the active isolation plate 801. Mounting side seats 805 are installed on both sides of the welding machine body 1. Synchronous drive columns 804 are rotatably installed on the two mounting side seats 805. Synchronous drive sleeves 803 are installed on the bottom side of both active isolation plates 801. The synchronous drive columns 804 are rotatably installed in the two synchronous drive sleeves 803. The synchronous drive columns 804 rotate to drive the two synchronous drive sleeves 803 to move, thereby driving the two active isolation plates 801 to move. It should be noted that, in this embodiment of the invention, when the synchronous drive column 804 rotates, it rotates within the two mounting side seats 805 through two limiting rotating rings 806. At the same time, the rotation of the synchronous drive column 804 drives the two synchronous drive sleeves 803 to move, and the movement of the two synchronous drive sleeves 803 drives the two active isolation plates 801 to move, thereby clamping the reinforcing bar and isolating the welding machine body 1 from the operator to avoid accidents.

[0031] Please continue to refer to the instruction manual appendix. Figures 2-4 Furthermore, the steel bar processing equipment for tunnel construction sites provided in this embodiment of the invention includes a bending anti-jump mechanism 7 that further includes two pull rods 706. Both pull rods 706 are slidably mounted on the integrated mounting sleeve 701, and both pull rods 706 are mounted on the pressing slide plate 705. In addition, two lifting springs 707 are installed on the downward pressing slide plate 705, and both lifting springs 707 are mounted on the integrated mounting sleeve 701. It should be noted that, in this embodiment of the invention, when the reinforcing bar is placed between the central bending column 4 and the follower bending column 5 for bending, the reinforcing bar presses down on the downward pressing slide plate 705, and the downward pressing slide plate 705 moves on the central bending column 4 and the follower bending column 5. At the same time, the downward movement of the downward pressing slide plate 705 drives the two pull rods 706 to move, and causes the two lifting springs 707 to be stretched by force.

[0032] More specifically, in this embodiment of the invention, the integrated mounting sleeve 701 has two snap-fit ​​slots 711, a snap-fit ​​shaft 709 is rotatably installed in the two snap-fit ​​slots 711, and a pressing rotating plate 710 is installed at both ends of the snap-fit ​​shaft 709. A snap-fit ​​push frame 708 is installed on the two pull rods 706. In addition, a snap-fit ​​torsion spring 712 is installed on the snap-fit ​​groove 711, and the snap-fit ​​torsion spring 712 is installed on the snap-fit ​​shaft 709. It should be noted that, in this embodiment of the invention, when the extrusion plate 710 is extruded and rotated, the extrusion plate 710 drives the snap-fit ​​shaft 709 to rotate, so that the snap-fit ​​shaft 709 rotates in the snap-fit ​​groove 711, and the snap-fit ​​torsion spring 712 is subjected to force. At the same time, the snap-fit ​​shaft 709 drives the rotating snap-fit ​​plate 703 to rotate, and the rotating snap-fit ​​plate 703 drives the snap-fit ​​anti-jump cover 702 to rotate and fasten onto the follower bending column 5.

[0033] More specifically, in this embodiment of the invention, a limiting stop strip 713 is installed on the integrated mounting sleeve 701. The limiting stop strip 713 is used to limit the rotation angle of the rotating fastening plate 703. It should be noted that, in this embodiment of the invention, by limiting the rotation angle of the rotating fastening plate 703 by the limiting stop strip 713, the rotating fastening plate 703 is kept tilted, thereby facilitating the compression of the rotating plate 710.

[0034] Please refer to the instruction manual attached. Figures 5-9 Furthermore, the steel bar processing equipment for tunnel construction sites provided in this embodiment of the invention includes a steel bar isolation clamping mechanism 8 that further comprises two adaptive clamping tooth plates 810. The two adaptive clamping tooth plates 810 are slidably mounted on two active isolation plates 801, and the adaptive clamping tooth plates 810 are used to close the active isolation plates 801. In addition, a locking tooth plate 811 is slidably mounted on the active isolation plate 801, and the locking tooth plate 811 meshes with the adaptive clamping tooth plates 810. It should be noted that in this embodiment of the invention, the adaptive clamping tooth plate 810 closes the steel bar movable groove 802, and the locking tooth plate 811 is used to lock the adaptive clamping tooth plate 810.

[0035] More specifically, in this embodiment of the invention, the active isolation plate 801 is provided with a lifting slide groove 812, and the locking tooth plate 811 is slidably mounted on the lifting slide groove 812; a locking spring 813 is installed on the bottom side of the locking tooth plate 811, and the locking spring 813 is installed on the inner wall of the bottom side of the lifting slide groove 812. It should be noted that, in this embodiment of the invention, when the locking tooth plate 811 moves, it moves vertically within the lifting slide groove 812, causing the locking spring 813 to be under force. Therefore, under the rebound force of the locking spring 813, it can help the locking tooth plate 811 to reset.

[0036] Please continue to refer to the instruction manual appendix. Figures 5-9 More specifically, in this embodiment of the invention, two limiting rotating rings 806 are sleeved on the synchronous drive column 804, and the two limiting rotating rings 806 are respectively rotatably installed in the two mounting side seats 805. Furthermore, two arc-shaped pushing grooves 807 are formed on the synchronous drive column 804, and arc-shaped pushing blocks 808 are installed on the inner walls of the two synchronous drive sleeves 803. The two arc-shaped pushing blocks 808 are respectively movably installed in the two arc-shaped pushing grooves 807. It should be noted that, in this embodiment of the invention, when the synchronous drive column 804 rotates, it rotates within the two mounting side seats 805 through two limiting rotating rings 806. At the same time, the rotation of the synchronous drive column 804 pushes the two arc-shaped pushing blocks 808 to move through the two arc-shaped pushing grooves 807, so that the two arc-shaped pushing blocks 808 drive the two synchronous drive sleeves 803 to move, thereby achieving the purpose of closing the two active isolation plates 801 by rotating the synchronous drive column 804.

[0037] Further, please refer to the appendix to the instruction manual. Figures 9-11 This invention provides a steel bar processing equipment for tunnel construction sites, which further includes a synchronous linkage mechanism 9. The synchronous linkage mechanism 9 is installed on a switch base 10, and both the bending anti-jump mechanism 7 and the steel bar isolation clamping mechanism 8 are connected to the synchronous linkage mechanism 9. The synchronous linkage mechanism 9 is used to drive the bending anti-jump mechanism 7 and the steel bar isolation clamping mechanism 8. It should be noted that, in this embodiment of the invention, by setting the synchronous linkage mechanism 9, when the welding machine body 1 is started by pressing the rebound pressing plate 6, it can drive the snap-on anti-jump cover 702 to rotate and snap onto the follow-up bending column 5, sealing the steel bar between the rotating snap-on plate 703 and the downward pressing slide plate 705. At the same time, it can drive the synchronous drive column 804 to rotate, so that the two active isolation plates 801 are closed, thereby clamping the steel bar and isolating the welding machine body 1 from the operator to avoid accidents.

[0038] More specifically, in this embodiment of the invention, the synchronous linkage mechanism 9 includes an ejection limiting frame 901, which is slidably mounted on the hand guard 11 and is engaged with the pressing slide plate 705. In addition, rotating push rods 902 are installed on both sides of the rebound pressing plate 6, and rotating push shafts 903 are rotatably mounted on both rotating push rods 902. Push grooves 904 are opened on both sides of the ejection limiting frame 901, and the two rotating push shafts 903 are slidably mounted in the two push grooves 904 respectively. It should be noted that, in this embodiment of the invention, when the spring-loaded pressing plate 6 is pressed, the spring-loaded pressing plate 6 rotates on the switch base 10, and the rotation of the spring-loaded pressing plate 6 drives the two rotating push rods 902 to rotate, so that the rotating push rods 902 drive the push-out limiting frame 901 to move through the rotating push shaft 903. At the same time, the rotating push shaft 903 slides in the push groove 904. When the push-out limiting frame 901 moves, it is stuck on the pressing slide plate 705, which can restrict the pressing slide plate 705 when the spring-loaded pressing plate 6 is bent.

[0039] Please continue to refer to the instruction manual appendix. Figures 9-11More specifically, in this embodiment of the invention, a mounting plate 905 is installed on one side of the switch base 10, a pressing linkage frame 906 is slidably installed on the mounting plate 905, and a toothed plate frame 909 is installed on the pressing linkage frame 906. A gear 908 is installed at one end of the synchronous drive column 804, and the gear 908 meshes with the toothed plate frame 909. In addition, a rising spring 907 is installed on the downward pressing linkage 906, and the rising spring 907 is mounted on the mounting plate 905. It should be noted that, in this embodiment of the invention, when the rebound pressing plate 6 is pressed, it compresses the downward pressing linkage 906 to move. The movement of the downward pressing linkage 906 causes the rising spring 907 to be stretched by force. At the same time, the movement of the downward pressing linkage 906 causes the toothed plate frame 909 to move, so that the toothed plate frame 909 drives the gear 908 to rotate. The rotation of the gear 908 drives the synchronous drive column 804 to rotate, thereby achieving the purpose of simultaneously driving the two active isolation plates 801 to actively close when the welding machine body 1 is started.

[0040] In summary, the working principle of the steel bar processing equipment for tunnel construction sites provided in this embodiment of the invention is as follows: When the reinforcing bar is placed between the central bending column 4 and the follower bending column 5 for bending, the reinforcing bar presses down on the downward pressing slide plate 705 and moves downward. The downward pressing slide plate 705 moves on the central bending column 4 and the follower bending column 5. At the same time, the downward movement of the downward pressing slide plate 705 drives the two pull rods 706 to move, and causes the two lifting springs 707 to be stretched. The movement of the pull rods 706 drives the snap-fit ​​push frame 708 to move, causing the snap-fit ​​push frame 708 to squeeze the squeezing rotating plate 710 to rotate. The squeezing rotating plate 710 drives the snap-fit ​​rotating shaft 709 to rotate, causing the snap-fit ​​rotating shaft 709 to rotate in the snap-fit ​​rotating groove 711, and causing the snap-fit ​​torsion spring 712 to be stressed. At the same time, the snap-fit ​​rotating shaft 709 drives the rotating snap-fit ​​plate 703 to rotate. The rotating snap-fit ​​plate 703 drives the snap-fit ​​anti-jump cover 702 to rotate and snap onto the follower bending column 5, thereby sealing the reinforcing bar between the rotating snap-fit ​​plate 703 and the downward pressing slide plate 705, preventing the reinforcing bar from jumping during bending. It should be noted that during bending, the rotating bending disc 2 drives the follower bending column 5 to rotate and bend the steel bar. At this time, the snap-fit ​​anti-jump cover 702 rotates. The rotation of the snap-fit ​​anti-jump cover 702 drives the integrated installation sleeve 701 to rotate through the rotating snap-fit ​​plate 703. This causes the integrated installation sleeve 701 to rotate on the snap-fit ​​sleeve 704, thereby achieving the purpose of fully restricting the steel bar during bending. Furthermore, during bending, pressing the spring-loaded pressing plate 6 causes it to rotate on the switch base 10. The rotation of the spring-loaded pressing plate 6 drives the two rotating push rods 902 to rotate, which in turn drives the push rods 902 to move the push-out limiting frame 901 via the rotating push shaft 903. At the same time, the rotating push shaft 903 slides within the push groove 904. When the push-out limiting frame 901 moves, it is locked onto the downward pressing slide plate 705. This allows the downward pressing slide plate 705 to be restricted when the spring-loaded pressing plate 6 is pressed for bending, ensuring that the reinforcing bar can be continuously restricted. In addition, when the spring-loaded pressing plate 6 is pressed, it compresses the downward pressing linkage frame 906 to move. The movement of the downward pressing linkage frame 906 causes the rising spring 907 to be stretched by force. The movement of the downward pressing linkage frame 906 also causes the toothed plate frame 909 to move, which in turn drives the gear 908 to rotate. The rotation of the gear 908 drives the synchronous drive column 804 to rotate. Furthermore, when the synchronous drive column 804 rotates, it rotates within the two mounting side seats 805 via two limiting rotating rings 806. Simultaneously, the rotation of the synchronous drive column 804 pushes two arc-shaped push blocks 808 to move via two arc-shaped push grooves 807. This causes the two arc-shaped push blocks 808 to move two synchronous drive sleeves 803, which in turn move two active isolation plates 801, thereby clamping the reinforcing bars and isolating the welding machine body 1 from the operator to prevent accidents. In addition, when the two active isolation plates 801 are closed, pressing down the two locking tooth plates 811... The movement causes the locking tooth plate 811 to move vertically within the lifting slide 812, and forces the locking spring 813. Simultaneously, the locking tooth plate 811 disengages from the adaptive clamping tooth plate 810. When the two active isolation plates 801 merge, the reinforcing bar presses against the two adaptive clamping tooth plates 810. After the two active isolation plates 801 merge, the two locking tooth plates 811 are released. Under the rebound force of the two locking springs 813, the two locking tooth plates 811 actively lock the two adaptive clamping tooth plates 810, further preventing the reinforcing bar from jumping during bending, thereby ensuring the safety of the reinforcing bar bending operation.
