Description

Technical Field

[0001] The present application relates to the technical field of feeding devices, and in particular to a continuous feeding device for automatically extending steel bars. Background Art

[0002] In tunnel engineering, grid arch frames are often used for initial support to provide temporary or permanent support structures for tunnels. Grid arch frames include an outer frame and butterfly ribs, which are welded inside the outer frame.

[0003] During the production process of butterfly ribs, rectangular frame ribs are first made, and then the rectangular frame ribs are bent into "8"-shaped ribs, and two "8"-shaped ribs are welded together to obtain butterfly ribs.

[0004] The production process of rectangular frame reinforcement is to first bend one end of the long steel bar into a rectangular frame reinforcement, then cut the bent rectangular frame reinforcement part, and then produce the next rectangular frame reinforcement. One steel bar can be used to make multiple rectangular frame reinforcements. When cutting, a little extra steel bar will be reserved. Therefore, the total length of the steel bar will be greater than the total length of multiple rectangular frame reinforcements, resulting in excess steel bar in the end, resulting in low utilization rate of the raw steel bar. Summary of the invention

[0005] In order to improve the utilization rate of raw steel bars, the present application provides an automatic extended steel bar continuous feeding device.

[0006] The present application provides an automatic steel bar continuous feeding device, which adopts the following technical solution:

[0007] A continuous feeding device for automatically extending steel bars comprises a fixed step plate and a movable step plate, wherein the movable step plate is arranged on one side of the fixed step plate, a driving assembly is arranged at the bottom of the movable step plate, and the driving assembly is used to drive the movable step plate to move back and forth up and down, a second unloading plate is arranged on one side of the top of the fixed step plate, a movable assembly is arranged at one end of the second unloading plate away from the fixed step plate, the movable assembly is used to move the steel bars, a first clamping device and a second clamping device are arranged at one end of the movable assembly, and the movable assembly, the first clamping device and the second clamping device are arranged in sequence along the moving direction of the steel bars.

[0008] By adopting the above technical solution, when the steel bars are transported to the top surface of the bottom step of the movable step plate, the movable step plate moves upward, thereby moving the steel bars to the top surface of the previous step of the fixed step plate. With the cooperation of the movable step plate and the fixed step plate, the steel bars make a movement similar to climbing stairs, moving the steel bars from the bottom of the fixed step plate to the top of the fixed step plate. After that, the steel bars move along the second blanking plate to the top surface of the movable assembly, and the movable assembly transports the steel bars.

[0009] When the tail end of the first steel bar moves to the input end before entering the second clamping device, the second clamping device is started, and the second clamping device clamps the first steel bar. After that, the second steel bar moves until one side of the head end of the second steel bar abuts against one side of the tail end of the first steel bar, and the first clamping device is started, and the first clamping device clamps the second steel bar. Finally, the operator welds the tail end of the first steel bar to the head end of the second steel bar, thereby connecting the remaining material of the first steel bar that cannot form a rectangular frame bar behind the first steel bar to the second steel bar, thereby utilizing the remaining material of the first steel bar, thereby improving the utilization rate of the raw steel bars.

[0010] Preferably, a first cutting device and a second cutting device are provided between the first clamping device and the second clamping device.

[0011] By adopting the above technical solution, there are arc-shaped parts at both ends of the steel bar, which makes the two ends of the steel bar relatively uneven. When the two steel bars are connected, there will be a concave part in the connecting part of the two steel bars, which makes the connecting part relatively weak, and the diameter is inconsistent with other parts, which will affect the use of the connected steel bars. Before welding, the arc part of the tail end of the first steel bar is cut by the second cutting device, so that the tail end of the first steel bar is flat, and the arc part of the head end of the second steel bar is cut by the first cutting device, so that the head end of the first steel bar is flat. Therefore, after the tail end of the first steel bar is welded to the head end of the second steel bar, the connecting part of the first steel bar and the second steel bar is relatively flat, and the diameter of the connecting part is consistent with the diameter of other parts, thereby reducing the impact of the connected steel bars during use.

[0012] Preferably, one side of the second unloading plate is rotatably connected to a transport plate, a stop plate is fixed to one end of the top surface of the transport plate away from the fixed step plate, and a telescopic driving member is assembled at the bottom of the transport plate.

[0013] By adopting the above technical solution, when the steel bars move from the transport plate and the top surface of the second movable plate, the movement of the steel bars can be paused under the action of the resistance plate, thereby controlling the speed of the steel bars and reducing the situation where the steel bars move too fast and fall outside the movable component.

[0014] Preferably, the driving assembly includes a driving member, a rotating shaft, a turntable and a swing rod, the output end of the driving member is assembled with one end of the rotating shaft, the turntable is fixed to the outer wall of the rotating shaft away from the end of the driving member, one end of the swing rod is hinged to one end of the turntable, and the other end of the swing rod is hinged to the bottom end of the movable step plate.

[0015] By adopting the above technical solution, the driving member is started, the driving member drives the rotating shaft to rotate, the rotating shaft drives the turntable to rotate, and the turntable drives the swing rod to move up and down, so that the swing rod drives the moving step plate to move up and down.

[0016] Preferably, the top surface of the movable step plate is an inclined surface, and the inclination direction is downward from the outside to the inside.

[0017] By adopting the above technical solution, the top surface of the movable step plate is inclined inward, so that when the steel bars move to the top surface of the movable step plate, the steel bars will move into the movable step plate. When the movable step plate drives the steel bars to move upward, the situation where the steel bars slide outward and fall off the top surface of the movable step plate is reduced.

[0018] Preferably, the top surface of the second blanking plate is inclined, and the top surface of the second blanking plate at one end close to the fixed step plate is higher than the top surface of the second blanking plate at one end close to the moving component.

[0019] By adopting the above technical solution, the top surface of the second blanking plate is inclined, and the top surface of the second blanking plate is lower near one end of the moving component, so that behind the top surface of the second blanking plate, the steel bars will move toward the moving component along the top surface of the second blanking plate under the action of gravity.

[0020] Preferably, a support frame is provided at the bottom of the moving component, and the moving component includes a rotating wheel, and the rotating wheel is rotatably connected to the top of the support frame.

[0021] By adopting the above technical solution, the steel bars are transported to the top surface of the rotating wheel, the moving component is started, the rotating wheel will rotate, and the steel bars will be driven to move.

[0022] Preferably, a placement groove is provided on the outer wall of the rotating wheel.

[0023] By adopting the above technical solution, under the action of the placement groove, the steel bars fall into the placement groove, thereby limiting the position of the steel bars and reducing the situation where the steel bars slide off the top surface of the rotating wheel.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When the tail end of the first steel bar moves to the input end before entering the second clamping device, the second clamping device is started, and the second clamping device clamps the first steel bar. After that, the second steel bar moves until one side of the head end of the second steel bar abuts against one side of the tail end of the first steel bar, and the first clamping device is started, and the first clamping device clamps the second steel bar. Finally, the operator welds the tail end of the first steel bar to the head end of the second steel bar, thereby connecting the remaining material behind the first steel bar that cannot form a rectangular frame bar with the second steel bar, thereby utilizing the remaining material of the first steel bar, thereby improving the utilization rate of the raw steel bars.

[0026] 2. Before welding, the arc portion of the tail end of the first steel bar is cut by the second cutting device to make the tail end of the first steel bar flat, and the arc portion of the head end of the second steel bar is cut by the first cutting device to make the head end of the first steel bar flat. Therefore, when the tail end of the first steel bar is welded to the head end of the second steel bar, the connection part of the first steel bar and the second steel bar is relatively flat, and the diameter of the connection part is consistent with the diameter of other parts, thereby reducing the impact of the connected steel bars during use.

When the steel bar is transported to the top surface of the step at the bottom of the movable step plate 22, the movable step plate 22 moves upward, thereby moving the steel bar to the top surface of the previous step of the fixed step plate 21. With the cooperation of the movable step plate 22 and the fixed step plate 21, the steel bar makes a movement similar to climbing stairs, and moves the steel bar from the bottom of the fixed step plate 21 to the top of the fixed step plate 21.
