Description

Technical Field

[0001] This utility model belongs to the technical field of ring-shaped steel bar bending and welding equipment, specifically relating to a single-bar splitting mechanism for steel bar feeding. Background Technology

[0002] Railway and highway construction requires a large amount of steel bars. Before use, most of the steel bars need to be bent. For ordinary bending, manual feeding is used. However, for bending steel bars with a diameter of 20mm or more, the conventional operation requires manual untying of the tied steel bars and two people to lift them from both ends to the feeding rollers. This is time-consuming, labor-intensive, and has low operational safety. Utility Model Content

[0003] The purpose of this invention is to provide a single-bar splitting mechanism for feeding steel bars, which enables automatic feeding, reduces the labor intensity of workers, and improves the safety factor.

[0004] The technical solution adopted by this utility model is a single-bar splitting mechanism for feeding steel bars, including double rollers. The double rollers are fixedly connected to the left and right sides of the drive shaft, and the two ends of the drive shaft are rotatably connected to the bearing seats. The bearing seats are fixedly connected to the support frame and one end extends out and is connected to the power drive mechanism. The double rollers are provided with notches at corresponding positions. The notches can accommodate a steel bar. When the notch is located on the lower side, the extracted steel bar can be automatically dropped.

[0005] Preferably, the roller surface of the above-mentioned double rollers is provided with multiple spot-welded protrusions, and the multiple protrusions are arranged alternately.

[0006] Preferably, the above-mentioned power drive mechanism adopts a variable speed motor, which is fixedly connected to the support frame. An arc-shaped cavity is provided on the front side wall of the inclined hopper facing the double rollers, and the arc-shaped cavity is coaxial with the double rollers.

[0007] Compared with the prior art, the beneficial effects of this utility model are that, in the design of this utility model, when a single steel bar in the inclined hopper falls to the notch, under the clockwise driving action of the drive shaft, the steel bar first reaches the discharge port. Due to the weight of the steel bar itself, it can automatically fall out from the discharge port and enter the sliding inclined surface. This structure is simple to disassemble and arrange, and can be rotated as needed to obtain the output of a single steel bar. The automatic feeding is simple. For large-diameter and long steel bars (diameter above 20mm and length above 4m), it avoids the time-consuming and laborious task of two people lifting and feeding the steel bars, and the safety is higher.

[0009] Figure 2 This is the front view of the single-bar splitting mechanism for rebar feeding. Detailed Implementation

[0010] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0011] Example 1

[0012] like Figure 1-2 As shown, a single-bar splitting mechanism for feeding rebar includes double rollers 113 located at a transverse strip-shaped discharge port 106. The double rollers 113 are fixedly connected to a drive shaft 114 on both sides. Both ends of the drive shaft 114 are rotatably connected to bearing seats 115, which are fixedly connected to a support frame 104 with one end extending out and connected to a power drive mechanism. U-shaped notches 116 are provided at corresponding positions on the double rollers 113, each notch capable of accommodating a single rebar 4. When the notch 116 is located on the lower side... The system can automatically drop the extracted steel bars 4. The single steel bars in the inclined hopper fall to the gap. Under the clockwise driving action of the drive shaft, the steel bars first reach the discharge port. Due to the weight of the steel bars, they can automatically fall out of the discharge port and enter the sliding inclined surface. The structure is easy to disassemble and arrange. It can be rotated as needed to obtain the output of single steel bars. The automatic feeding is simple. For large diameter and long steel bars (diameter above 20mm and length above 4m), it avoids the time-consuming and laborious manual lifting of two people for feeding, and the safety is higher.

[0013] The roller surface of the double roller 113 is provided with multiple spot-welded protrusions. The multiple protrusions are arranged in an alternating manner, which can improve the rolling friction, making it easier to straighten the steel bars and enter the notch, and improving the accuracy of inserting them into the notch.

[0014] The power drive mechanism adopts a variable speed motor 125, which is fixedly connected to the support frame 104. The front side wall of the inclined hopper 105 opposite the double rollers 113 is provided with an arc-shaped cavity 126. The arc-shaped cavity 126 is coaxial with the double rollers 113, which can provide a rotation cavity for the double rollers 113 to rotate and facilitate the rotation of the double rollers.

[0015] The single-strand splitting mechanism for rebar feeding works in conjunction with the rebar feeding mechanism. The feeding mechanism 1 includes a unbinding mechanism 101, a single-strand splitting mechanism 102, and a single-strand conveying mechanism 103. The unbinding mechanism 101 is installed on the top of the support frame 104, and a sloping hopper 105 is provided on the top of the support frame 104. The single-strand splitting mechanism 102 is installed at the transverse strip-shaped discharge port 106 of the sloping hopper 105. The single-strand conveying mechanism 103 is installed at the bottom of the sloping surface of the support frame 104 and is used to feed the rebar 4 fed by the single-strand splitting mechanism 102 into the feed port of the rebar bending machine 2. The transverse strip-shaped discharge port 106 and the single-strand conveying mechanism 103 are connected by a sliding sloping surface 121. The slope 121 is fixedly connected to the support frame 104, and its lower end is slightly higher than the traveling sliding wheel 117 of the single-strand conveying mechanism 103. The multiple steel bars that are hoisted and bound are untied by the untying mechanism and loosely placed in the inclined hopper. The single-strand splitting mechanism is used to split the steel bars in the inclined hopper one by one and feed them into the single-strand conveying mechanism. The feeding mechanism greatly reduces the labor intensity (when bending steel bars with a diameter of more than 20mm and a length of more than 4m, the conventional operation requires manual untying of the tied steel bars and two people to lift the material at both ends and put it into the feeding roller and push it into the steel bar bending machine for bending). It saves time and effort, eliminates the need for manual untying and feeding, and makes the operation safer.

[0016] The unbinding mechanism 101 includes a horizontal linear travel module 107, a traveling frame 108, a lifting cylinder 109, a pneumatic finger 110, and a rotary cylinder 111. The horizontal linear travel module 107 is fixedly connected to the top edge of the support frame 104. The support frame 104 has an inverted L-shaped structure, and its lower end is fixedly connected to the slider of the horizontal linear travel module 107 via a flange. The horizontal free end of the support frame 104 is fixedly connected to the lifting cylinder 109 via a flange plate 124. The lifting cylinder 109 is a double-rod cylinder, and its lower end is fixedly connected to the rotary cylinder 111 via a connecting plate. The rotary table of the rotary cylinder 111 is connected to the inverted L-shaped finger. The bracket 123 is fixedly connected to the pneumatic finger 110. The clamping end of the pneumatic finger 110 can clamp the spiral knot of the tied steel wire. By clamping the top of the knotted steel wire with the pneumatic finger, the rotary cylinder is driven to rotate and loosen the spirally tied steel wire. After loosening, the pneumatic finger is used again to clamp the loosened steel wire at one end and lift it up, thereby pulling out the steel wire, realizing the untying function. The untying is fast and stable. The support frame 104 is equipped with a camera 112 at its horizontal free end. Through the camera, the knot of the steel wire tied with the rebar can be quickly and accurately identified. If it is not in a suitable position, it can be moved slightly by hand to facilitate the pneumatic finger to stably clamp and rotate to loosen the spirally tied steel wire.

[0017] To avoid hoisting and transporting bundled steel bars into the inclined hopper, the traveling frame 108 is connected to the slider of the horizontal linear traveling module 107 via an electric turntable 122. By rotating the traveling frame via the electric turntable, the structure at the pneumatic finger is rotated to the rear, freeing up space above the inclined hopper, making it easier to hoist and unload the bundled steel bars, thus improving safety.

[0018] The gripping surface of the pneumatic finger 110 is provided with anti-slip texture, which can improve gripping stability and reliability.

[0019] To facilitate more precise clamping, an upper horizontal linear module that moves back and forth is installed on one side of the horizontal beam of the walking frame 108. The lifting cylinder 109 is connected to the slider of the upper horizontal linear module through the flange plate 124, which enables the pneumatic fingers to move back and forth, making it easier for the pneumatic fingers to move laterally and longitudinally as well as to quickly position vertically, thus improving positioning accuracy. For untying at least two binding wires, the untying efficiency is greatly improved.

[0020] The single-strand conveying mechanism 103 includes multiple traveling sliding wheels 117. The grooves of the traveling sliding wheels 117 are V-shaped and can accommodate a single steel bar. The traveling sliding wheels 117 are rotatably connected to the bottom of the inclined surface of the support frame 104. A double-groove pulley 118 is connected to one side of the traveling sliding wheel 117 after it extends out of the rotating part. Adjacent double-groove pulleys 118 are connected by a belt 119. The double-groove pulleys 118 are connected to the drive pulley of the feeding drive motor 120 by a belt. The feeding drive motor 120 is mounted on the support frame 104 and is driven by the feeding drive motor, thereby driving all the grooved wheels to rotate and feed materials. The feeding is stable and reliable.

[0021] Instructions for use: The feeding mechanism unties the bundled steel bars and feeds each steel bar individually to the feed inlet of the steel bar bending machine. Under the action of the guide wheel group and feeding rollers of the steel bar bending machine, the bending machine moves forward to the set position. The end of the bending machine is supported on the auxiliary support walking platform. The steel bar bending machine performs the bending operation, and the auxiliary support walking platform follows the machine. After the bending is completed, the bent steel bar is disassembled, and the auxiliary support walking platform moves to the starting position to continue bending the next steel bar.
