Description

Technical Field

[0001] This utility model belongs to the field of horizontal bending processing technology of reinforcing bars, and specifically relates to a reinforcing bar alignment device for a horizontal bending processing unit of reinforcing bars. Background Technology

[0002] CNC horizontal bending equipment for reinforcing bars typically includes a fixed bending machine anchored to the foundation and a movable bending machine. The distance between the two bending machines is adjusted by moving the movable bending machine to accommodate reinforcing bars of different lengths. For batch processing of reinforcing bars, consistency is crucial. Therefore, the reinforcing bars need to be adjusted to a reference position after arriving at the bending machine and before bending. Currently, a reference baffle is usually installed on the fixed bending machine. After the reinforcing bars arrive, the operator manually pulls and pushes them onto the reference baffle. This method is not only physically demanding for the operator but also inefficient, failing to achieve true automated production. Utility Model Content

[0003] The technical problem to be solved by this utility model is to make up for the shortcomings of the prior art and provide a rebar alignment device for a horizontal rebar bending processing unit.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A rebar alignment device for a horizontal rebar bending processing unit includes a first alignment mechanism and a second alignment mechanism. The first alignment mechanism is disposed on the side of the fixed bending machine away from the movable bending machine, and the second alignment mechanism is disposed on the side of the movable bending machine away from the fixed bending machine.

[0006] The first alignment mechanism includes a reference plate and a first drive mechanism. The reference plate is hinged to the fixed bending machine. The first drive mechanism is used to drive the reference plate to rotate. When the first drive mechanism is in state I, the reference plate rotates to face the movable bending machine and is in a vertical state. When the first drive mechanism is in state II, the reference plate rotates to face upward and is in a horizontal state.

[0007] The second alignment mechanism includes a push plate, a tilting frame B, a second drive mechanism, and a third drive mechanism. The tilting frame B is hinged to the movable bending machine. The second drive mechanism is used to drive the tilting frame B to rotate. The tilting frame B includes a mounting surface. When the second drive mechanism is in state III, the mounting surface rotates to face the fixed bending machine and is in a vertical state. When the second drive mechanism is in state IV, the mounting surface rotates to face upward and is in a horizontal state. The push plate is fixed to the tilting frame B through the third drive mechanism, which is used to drive the push plate to move closer to and away from the mounting surface.

[0008] Furthermore, the first alignment mechanism also includes a flipping frame A, on which the reference plate is fixed, and the flipping frame A is hinged to the fixed bending machine; the first driving mechanism is a telescopic rod A, with the fixed end A of the telescopic rod A hinged to the fixed bending machine, and the telescopic end A of the telescopic rod A hinged to the flipping frame A; state I is the extended state of the telescopic rod A, and state II is the shortened state of the telescopic rod A.

[0009] Furthermore, the telescopic rod A is a pneumatic cylinder or an electric cylinder.

[0010] Furthermore, the second driving mechanism is a telescopic rod B, with its fixed end A hinged to the movable bending machine and its telescopic end B hinged to the tilting frame B; state III is the extended state of the telescopic rod B, and state IV is the shortened state of the telescopic rod B; the third driving mechanism is a telescopic rod C, with its fixed end C fixedly connected to the mounting surface of the tilting frame B, and its telescopic end C fixedly connected to the mounting surface.

[0011] Furthermore, the telescopic rods B and C are either pneumatic cylinders or electric cylinders.

[0012] The beneficial effects that this utility model can achieve are as follows:

[0013] When the steel bar arrives at the mold of the bending machine, the first drive mechanism and the top push plate are gradually rotated to a vertical position facing each other, so that both ends of the steel bar are pushed between the reference plate and the top push plate. Then, the third drive mechanism pushes one end of the steel bar onto the reference plate. In this way, the consistency of the bending position of the steel bars in the same batch can be guaranteed.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] The existing horizontal bending unit for reinforcing bars includes a fixed bending machine 99, a movable bending machine 97, and a track component 98. Both the fixed bending machine 99 and the track component 98 are fixed to the foundation. The movable bending machine 97 is slidably connected to the track component 98. The movable bending machine 97 moves along the track to approach or move away from the fixed bending machine 99, thus accommodating the processing of reinforcing bars of different lengths. Figure 1 As shown, the fixed bending machine 99 is located to the left of the movable bending machine 97, thus defining the up, down, left, and right directions. This directional setting is merely for the convenience of describing this embodiment. When the reinforcing bar reaches the mold of the bending machine, the positions of both ends of the reinforcing bar may not be at a uniform reference position; some may be biased to the left, and some to the right. Due to the existence of the existing automatic feeding mechanism, the offset is generally not too large.

[0024] A rebar alignment device for a horizontal rebar bending processing unit, such as Figure 1 As shown, it includes a first alignment mechanism 1 and a second alignment mechanism 2. The first alignment mechanism 1 is located on the left side of the fixed bending machine 99, and the second alignment mechanism 2 is located on the right side of the movable bending machine 97.

[0025] like Figure 2 and Figure 4 As shown, the first alignment mechanism 1 includes a telescopic rod A101 (which can be a pneumatic or electric cylinder), a tilting frame A102, and a reference plate 103. The reference plate 103 is fixed to the tilting frame A102, which is hinged to the fixed bending machine 99. The telescopic rod A101 drives the tilting frame A102 to rotate. The fixed end A of the telescopic rod A101 is hinged to the fixed bending machine 99, and the telescopic end A of the telescopic rod A101 is hinged to the tilting frame A102. When the telescopic rod A101 is in an extended state, the reference plate 103 rotates to face the movable bending machine 97 and is in a vertical state. When the telescopic rod A101 is in a shortened state, the reference plate 103 rotates to face upward and is in a horizontal state.

[0026] like Figure 3 , Figure 5 and Figure 6 As shown, the second alignment mechanism 2 includes a push plate 204, a tilting frame B202, a telescopic rod B201, and a telescopic rod C203. The tilting frame B202 includes a mounting surface 2021 and is hinged to the movable bending machine 97. The telescopic rod B201 is used to drive the tilting frame B202 to rotate. The fixed end A of the telescopic rod B201 is hinged to the movable bending machine 97, and the telescopic end B of the telescopic rod B201 is hinged to the tilting frame B202. When the telescopic rod B201 is in an extended state, the mounting surface 2021 rotates to face the fixed bending machine 99 and is in a vertical state. When the telescopic rod B201 is in a shortened state, the mounting surface 2021 rotates to face upwards and is in a horizontal state. The fixed end C of the telescopic rod C203 is fixedly connected to the mounting surface 2021 of the tilting frame B202, and the push plate 204 is fixedly connected to the telescopic end C of the telescopic rod C203. Both telescopic rods B201 and C203 can be pneumatic or electric cylinders.

[0027] In this embodiment, when the reinforcing bar reaches the mold of the bending machine, the telescopic rods A101 and B201 are activated, causing the reference plate 103 and the push plate 204 to gradually rotate until they are vertically aligned face-to-face. This pushes the reinforcing bar that is off to the left to the right and the reinforcing bar that is off to the right to the left. Furthermore, to ensure smooth rotation of the reference plate 103 and the push plate 204, the distance between them is generally slightly greater than the length of the reinforcing bar after both are vertical. Based on this, the telescopic rod C203 is further activated, pushing the right end of the reinforcing bar to the left, so that the left end of the reinforcing bar abuts against the reference plate 103. This ensures the consistency of the bending position of the reinforcing bars processed in the same batch.

[0028] In the description of this utility model, terms such as "inner", "outer", "upper", "lower", "front", and "rear" that indicate orientation or positional relationship are used only for the convenience of describing this utility model, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
