Description

Technical Field

[0001] The invention relates to the technical field of steel bar bending, in particular to a steel bar bending machine. Background Art

[0002] The steel bars are combined together to form a complete grid, which is figuratively called "steel cage", "steel mesh", "steel skeleton", etc. A complete steel grid is conducive to restraining concrete and improving the integrity of concrete components.

[0003] In the process of assembling the steel bar skeleton, steel bar components of various shapes are required. Some steel bar components will be bent and fixed on the skeleton on site. Some steel bar components with more complex shapes or relatively high size requirements need to be bent uniformly by a steel bar bending machine. The existing axis-wrap steel bar bending machine is not easy to bend the steel bar continuously forward and backward without reloading the steel bar. When bending components that are in a cross state during bending, the existing bending machines generally bend the parts at both ends in turn first, and then bend the middle part, avoiding the crossing or placing the bending that will cause the crossing state at the end, so that a single bending head will increase the number of times the steel bar is disassembled and assembled on the bending machine when bending. Some bending machines use two bending heads to bend synchronously from both ends to the middle. Although they can be bent continuously, they need to add a moving rail and a bending head for the bending head, which occupies a large area and increases the equipment cost. Therefore, a steel bar bending machine that is convenient for continuous bending of steel bars is needed. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 7In an embodiment of the present invention, a steel bar bending machine includes a conveying mechanism 600, which is used to convey steel bars, and also includes a housing 100, a switching mechanism 200, a driving mechanism 300, an actuator 400, a ring frame 500 and a slide 700. A support seat 110 is fixedly installed inside the housing 100, and a support ring 120 is fixedly installed on the inner wall of the support seat 110. The actuator 400 includes two shafts 410 with adjustable spacing, one end of the shaft 410 is rotatably sleeved with an extrusion wheel 412, the ring frame 500 is rotatably connected to one end of the support ring 120, and one side of the ring frame 500 is rotatably connected to a rail rod 510, and the rail rod 510 is rotatably connected to the rail rod 510. 10 is provided with a long groove 511, and the two shafts 410 are slidably connected with the long groove 511. The switching mechanism 200 is fixedly installed on the support ring 120. The switching mechanism 200 includes an axis module 250, and the axis module 250 is used to dock with the other end of the shaft 410. The axis module 250 is movable. The driving mechanism 300 is fixedly installed inside the shell base 100, and the driving mechanism 300 is used to drive the ring frame 500 to rotate.

[0040] Specifically, the steel bar is made to pass through between the two extrusion wheels 412, and the spacing between the two shafts 410 is adjusted so that the two extrusion wheels 412 clamp the steel bar. When the steel bar needs to be bent downward, the axis module 250 moves to a coaxial position with a shaft 410 at the lower position, and then the ring frame 500 is driven to rotate forward through the driving mechanism 300, and the ring frame 500 drives the two shafts 410 to rotate around one shaft 410, so that the extrusion wheel 412 at the upper position revolves around the extrusion wheel 412 at the lower position, thereby driving the steel bar to bend downward. After bending in place, the ring frame 500 rotates, driving the two shafts 410 and the rail rod 510 to rotate To the initial angle, when it is necessary to bend the steel bar upward, the axis module 250 moves to a position coaxial with the other shaft 410, and the ring frame 500 is reversed, so that the extrusion wheel 412 located below rotates around the extrusion wheel 412 located above, so as to achieve the upward bending of the steel bar. By controlling the offset of the conveying mechanism 600, the steel bar is input at a certain angle to the extrusion wheel 412, so that when the steel bar is bent, the bent portion is spirally shaped, so that during the bending process of the entire steel bar component, after the overall bending angle exceeds one hundred and eighty degrees, the two ends of the component are misaligned and do not interfere with each other, so as to facilitate continuous bending of the steel bar from one end to the other.

[0043] In this embodiment, in the initial position, the inclination angles of the track rod 510 and the notches on the fixed seat sleeve 251 are the same. At this time, the upper notch of the core sleeve 252 is aligned with the upper notch of the fixed seat sleeve 251, and the transmission motor 240 drives the transmission screw 230 to rotate, thereby driving the axis module 250 to slide along the length direction of the slide rail 210 through the transmission screw 230, thereby driving the axis module 250 to switch between the pin heads 411 at the other ends of the two shafts 410. When the core sleeve 252 is coupled with a pin head 411, when the track rod 510 drives the shaft 410 to rotate, the pin head 411 drives the core sleeve 252 and the fixed seat sleeve 251 to be misaligned, so that the fixed seat sleeve 251 limits the shaft 410 through the pin head 411.

[0044] like Figures 6 to 9As shown, in the present embodiment, the outer wall of the fixed seat sleeve 251 is rotatably connected to the outer limit frame 253, the outer wall of the outer limit frame 253 is fixedly connected to two parallel side rods 254, and the two shaft rods 410 are located between the two side rods 254, and the two shaft rods 410 can slide between the two side rods 254, the inner wall of the support ring 120 is fixedly connected to the support rod 121, one end of the support rod 121 is fixedly connected to two blocking rods 122, the blocking rod 122 is located between the side rod 254 and the rail rod 510, a bridge frame 423 is fixedly connected to the middle position of one side wall of the outer frame 420, a blocking rod 2 424 is fixedly connected to the middle position of one side wall of the bridge frame 423, and the spacing between the two blocking rods 122 is equal to the outer diameter of the blocking rod 2 424.

[0045] During specific implementation, through the setting of the side rod 254, when the fixed seat sleeve 251 is disengaged from the two pin heads 411 during the process of moving from one pin head 411 position to another pin head 411, the side rod 254 contacts the two shaft rods 410 to limit the rail rod 510 and the two shaft rods 410, so as to prevent the rail rod 510 from driving the two shaft rods 410 to tip over. At the same time, through the setting of the second shift rod 424, when the actuator 400 is deflected to the initial position, the second shift rod 424 just fits into the position of the two shift rods 122, so as to prevent the outer frame 420 and the two shaft rods 410 from being pushed downward along the rail rod 510, so as to achieve that when in the initial position, the position of the axis module 250 is adjusted, and the actuator 400 maintains the angle and position unchanged.

[0046] Embodiment 2

[0047] like Figures 2 to 10 As shown, in this embodiment, the driving mechanism 300 includes a servo motor 330 and a gear ring 310, the gear ring 310 is fixedly connected to the ring frame 500, the outer wall of the support seat 110 is rotatably connected with a gear 320, the gear 320 is meshed with the gear ring 310, the output end of the servo motor 330 is transmission-connected with the gear 320, the servo motor 330 is fixedly installed inside the shell seat 100, the other side wall of the outer frame 420 is fixedly connected with a partition plate 430, one side of the partition plate 430 An avoidance groove is opened on the wall, and the adjustment module 710 includes a mounting frame 713, the inner wall of the mounting frame 713 is rotatably connected with an internal threaded sleeve 712, the inner wall of the internal threaded sleeve 712 is screwed and connected with a screw 711, one end of the screw 711 is rotatably connected to the conveying mechanism 600, and an arc-shaped slide rail 210 is arranged on the top surface of the slide seat 700, and the conveying mechanism 600 is slidably connected with the arc-shaped slide rail 210, and the central axis of the arc-shaped slide rail 210 passes through the middle position between the two extrusion wheels 412.

[0048] During specific implementation, the outer frame 420 is set to facilitate confining the steel bars on the extrusion wheel 412. The screw 711 is manually rotated through the setting of the adjustment module 710, thereby driving the conveying mechanism 600 to move along the arc-shaped slide rail 210 to adjust the offset angle of the conveying mechanism 600, thereby facilitating the adjustment of the lateral angle of the steel bars when they are input between the two extrusion wheels 412 as needed, and facilitating the adjustment of the staggered distance between the two ends of the member when the two ends cross according to the structure of the steel bar member and the diameter of the steel bar.

Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0051] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
