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 feeding mechanism for a large-diameter steel bar bending device. 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. Ordinary bending is done by manually feeding the steel bars. However, when bending steel bars with a diameter of 20mm or more, manual feeding is time-consuming, labor-intensive, and labor-intensive. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a feeding mechanism for a large-diameter steel bar bending device, thereby solving the problem of time-consuming and labor-intensive manual feeding of large-diameter steel bars.

[0004] The technical solution adopted by this utility model is a feeding mechanism for a large-diameter steel bar bending device. The feeding mechanism includes an unbinding mechanism, a single-bar splitting mechanism, and a single-bar conveying mechanism. The unbinding mechanism is installed on the top of the support frame, and a sloping hopper is provided on the top of the support frame. The single-bar splitting mechanism is installed at the transverse strip-shaped discharge port of the sloping hopper, and the single-bar conveying mechanism is installed at the bottom of the sloping surface of the support frame, for feeding the steel bars fed out by the single-bar splitting mechanism into the feed port of the steel bar bending machine.

[0005] Preferably, the untying mechanism includes a horizontal linear walking module, a walking frame, a lifting cylinder, a pneumatic finger, and a rotary cylinder. The horizontal linear walking module is fixedly connected to the top of the support frame. The support frame has an inverted L-shaped structure, with its lower end fixedly connected to the slider of the horizontal linear walking module. A lifting cylinder is fixedly connected to the horizontal free end of the support frame. The lifting cylinder is a double-rod cylinder. A rotary cylinder is fixedly connected to the lower connecting plate. A pneumatic finger is fixedly connected to the rotary table of the rotary cylinder. The gripping end of the pneumatic finger can grip the spiral knot of the tied steel wire. A camera is provided at the horizontal free end of the support frame.

[0006] Preferably, the aforementioned walking frame is connected to the slider of the horizontal linear walking module via an electric turntable, and an upper horizontal linear module that moves back and forth is installed on one side of the horizontal beam of the walking frame. The lifting cylinder is connected to the slider of the upper horizontal linear module via a flange plate.

[0007] Preferably, the above-mentioned single-piece splitting mechanism includes double rollers, which are located at the transverse strip-shaped discharge port. The double rollers are fixedly connected to the drive shaft on the left and right sides respectively. 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. A U-shaped notch is provided at the corresponding position on the double rollers. The notch can accommodate a steel bar. When the notch is located on the lower side, the extracted steel bar can be automatically dropped.

[0008] Preferably, the above-mentioned power drive mechanism adopts a variable speed motor, which is fixedly connected to the support frame.

The double groove pulleys are connected to the drive pulley of the feeding drive motor by a belt. The feeding drive motor is mounted on the support frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are that the feeding mechanism provided by this utility model uses an untying mechanism to untie multiple steel bars that are hoisted and bound, and place them loosely in the inclined hopper. The single-bar splitting mechanism then splits the steel bars in the inclined hopper into individual bars and feeds them into the single-bar conveying mechanism. The feeding mechanism greatly reduces labor intensity (for bending steel bars with a diameter of more than 20mm and a length of more than 4m, conventional operation requires manual untying of the bound steel bars, and two people to lift and unload them onto the feeding rollers at both ends and push them into the steel bar bending machine for bending). It saves time and effort, eliminates the need for manual untying and unloading, and improves operational safety. Attached Figure Description

[0013] 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.

[0014] Example 1

[0015] like Figure 1-2As shown, a feeding mechanism for a large-diameter rebar bending device 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 a 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 inlet 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 sliding sloping surface 121 is fixedly connected. The sliding roller 117 of the single-strand conveying mechanism 103 is attached to the support frame 104 and slightly higher than the lower end of the sliding roller 117. The multiple steel bars that are hoisted and bound are loosely placed in the inclined hopper 105 by the unbinding mechanism 101. The single-strand splitting mechanism 102 splits the steel bars in the inclined hopper 105 into individual strands and feeds them into the single-strand conveying mechanism 103. The feeding mechanism 1 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 bound steel bars and two people to lift and unload them onto the feeding rollers at both ends and push them into the steel bar bending machine for bending). It saves time and effort, eliminates the need for manual unbinding and unloading, and improves the safety of operation.

[0016] To reduce the spiral tension of the steel wires during the untying of the reinforcing bars, the untying 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. 09 adopts a double-rod cylinder, with a rotary cylinder 111 fixedly connected to the lower connecting plate. The rotary table of the rotary cylinder 111 is fixedly connected to the pneumatic finger 110 through an inverted L-shaped finger bracket 123. The clamping end of the pneumatic finger 110 can clamp the spiral knot of the bound steel wire. By clamping the top of the knotted steel wire with the pneumatic finger 110, the rotary cylinder 111 is driven to rotate and loosen the spirally bound steel wire. After loosening, the pneumatic finger 110 is used again to clamp the loosened steel wire and lift it up to pull the steel wire out, thus realizing the unbinding function, which is fast and stable.

[0017] A camera 112 is installed at the horizontal free end of the support frame 104. The camera 112 can quickly and accurately identify the knot of the steel wire binding the steel bars. If it is not in the right position, it can be moved slightly by hand to facilitate the pneumatic fingers 110 to stably clamp and rotate to loosen the spiral knotted steel wire. In order to avoid hoisting the bound steel bars into the inclined hopper 105, the traveling frame 108 is connected to the slider of the horizontal linear traveling module 107 through the electric turntable 122. By rotating the traveling frame 108 through the electric turntable 122, the structure at the pneumatic fingers 110 is rotated to the rear, making room above the inclined hopper of the vehicle, which is convenient for hoisting and unloading the bound steel bars, and is safer.

[0018] The gripping surface of the pneumatic finger 110 is provided with anti-slip texture, which can improve gripping stability and reliability. To facilitate more precise gripping, an upper horizontal linear module that moves back and forth is installed on one side of the horizontal beam of the traveling 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 finger 110 to move back and forth. This facilitates the lateral and longitudinal movement of the pneumatic finger 110 and rapid vertical positioning, improving positioning accuracy. For untying at least two binding wires, the untying efficiency is greatly improved.

[0019] To facilitate the splitting and arrangement of materials for feeding into the single-material conveying mechanism, the single-material splitting mechanism 102 includes double rollers 113. The double rollers 113 are located at the transverse strip-shaped discharge port 106. The left and right sides of the double rollers 113 are fixedly connected to a drive shaft 114, and both ends of the drive shaft 114 are rotatably connected to bearing seats 115. The bearing seats 115 are fixedly connected to a support frame 104, with one end extending and connected to the power drive mechanism. U-shaped notches 116 are provided at corresponding positions on the double rollers 113. The notches 116 can accommodate one steel bar 4. When the notches 116 are located on the lower side, they can... The extracted steel bar 4 falls automatically. The single steel bar in the inclined hopper 105 falls to the notch 116. Under the clockwise driving action of the drive shaft 114, the steel bar 4 first reaches the discharge port 106. Due to the weight of the steel bar 4, it can automatically fall out from the discharge port 106 and enter the sliding inclined surface. This structure is easy to disassemble and arrange. It 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, and the safety is higher.

[0020] The rollers of the double rollers 113 are provided with multiple spot-welded protrusions on their roller surfaces. The multiple protrusions are staggered, which can improve the rolling friction and make it easier to straighten the steel bars and enter the notch 116, thus improving the accuracy of the notch insertion.

[0021] 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.

[0022] To enable single-strand directional conveying to the feed inlet of the bending device, the single-strand conveying mechanism 103 includes multiple traveling sliding wheels 117. The grooves of the traveling sliding wheels 117 are V-shaped, capable of accommodating a single steel bar. The traveling sliding wheels 117 are rotatably connected to the bottom of the inclined surface of the support frame 104. One side of the traveling sliding wheel 117 extends out of its rotating part and is connected to a double-groove pulley 118. 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 via 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, ensuring stable and reliable feeding.

[0023] 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.
