Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing, in particular to an intelligent device for automatic processing of steel bar threads. Background Art

[0002] Rebar, a common construction material, is typically made of high-strength, corrosion-resistant steel. It is widely used in construction and infrastructure projects, primarily to enhance the strength and durability of concrete structures. Rebar is typically cylindrical and comes in various diameters and lengths, selected and processed according to specific project requirements. Threading is a common rebar processing method used to create threads on the ends or lengths of rebar for connection to other components or structures. Common methods include mechanical thread rolling and cut thread rolling.

[0003] The existing steel bar thread processing equipment generally fixes and clamps the steel bar, drives the chuck and the sleeve inside it to rotate when the motor rotates, and manually adjusts the position of the motor to allow the steel bar to be inserted into the sleeve. The thread groove opened inside the sleeve rotates and contacts with the outer surface of the steel bar, thereby realizing the processing of the steel bar thread. However, since the existing steel bar thread processing equipment generally uses manual control of the position of the motor to achieve the length of the thread opened on the steel bar surface, manual control of the thread length is low in efficiency and poor in quality. Utility Model Content

The steel bar locking device is installed in the locking area. A linear moving mechanism is fixed on the processing area. The thread processing device is fixed on the movable end of the linear moving mechanism. The steel bar locking device is used to fix the steel bar to be processed. The thread processing port of the thread processing device faces the steel bar to be processed, and the thread processing port is coaxially arranged with the steel bar to be processed. The linear moving mechanism drives the thread processing device to approach or move away from the steel bar locking device to realize thread processing.

[0008] In this embodiment, a ball nut is fixed to the slider, and the slider is threadedly connected to the screw rod through the ball nut.

[0009] In this embodiment, an encoder for monitoring the number of rotations of the screw is installed at one end of the screw, and the encoder is connected to the controller.

[0010] The cam is fixed on the locking area, and the top of the fixing bracket is provided with a horizontally arranged sliding groove, and the sliding groove is arranged perpendicular to the central axis of the threaded processing port. A screw is arranged to rotate in the sliding groove, and two threaded sections with opposite thread directions are symmetrically arranged on the screw. The two clamping plates are slidably fitted in the sliding groove and the two clamping plates are respectively threadedly assembled on the two threaded sections. The two clamping plates respectively extend from the top of the sliding groove to form clamping ends, and an anti-slip layer is fixed on the opposite side of the clamping ends of the two clamping plates.

The processing motor is fixed on the slider, the chuck is coaxially fixed on the output shaft of the processing motor, and the rolling sleeve is fixed on the processing motor through the chuck, so that the rolling sleeve is coaxially arranged with the output shaft of the processing motor.

[0012] With the above structure, the device has the following advantages:

[0013] 1. This application combines a linear motion mechanism with a thread processing device to realize the automation of thread processing. The linear motion mechanism can control the length of the thread opened on the surface of the steel bar, thereby improving processing efficiency.

[0028] Furthermore, an extension bracket 7 is fixed to the thread processing device, and an end of the extension bracket 7 extends from one side of the thread processing port of the thread processing device. An object sensor 8 is installed on the extended end of the extension bracket 7, and the object sensor 8 faces the central axis of the thread processing port; the object sensor 8 and the thread processing device are both connected to a controller 9;

[0029] like Figure 2 、 3 As shown, the linear motion mechanism includes a guide rod 2, a slider 3, a screw rod 5, and a drive motor 6. The screw rod 5 is rotatably mounted on the processing area and is driven to rotate by the drive motor 6.

The screw rod 5 is threadedly mounted with a slider 3, and both sides of the slider 3 are slidably mounted on the guide rod 2. The thread processing equipment is fixed to the slider 3. Furthermore, a ball nut 4 is fixed to the slider 3, and the slider 3 is threadedly connected to the screw rod 5 via the ball nut 4. An encoder 10 is installed at one end of the screw rod 5. The encoder 10 is connected to the controller 9 and is used to monitor the number of rotations of the screw rod.

[0030] like Figure 4As shown, the steel bar locking device includes a fixed bracket 12, a clamping plate 13, a screw 14 and a rotating handle 15. The fixed bracket 12 is fixed on the locking area, and the top of the fixed bracket 12 is provided with a horizontally arranged sliding groove, and the sliding groove is arranged perpendicular to the central axis of the thread processing port of the thread processing equipment. A screw 14 is rotated in the sliding groove, and two threaded sections with opposite thread directions are symmetrically arranged on the screw 14. The two clamping plates 13 are slidably fitted in the sliding groove and the two clamping plates 13 are respectively threadedly assembled on the two threaded sections.

The rotation of the screw rod 5 drives the slider 3 to move along the screw rod 5. The slider 3 drives the thread processing equipment to move and approaches one end of the steel bar by moving. When the slider 3 moves, it will simultaneously drive the extension bracket 7 installed on its top surface to move, and the object sensor 8 installed on the extension bracket 7 detects When the presence of steel bars is detected, the controller 9 controls the processing motor 16 of the thread processing equipment to start, and the processing motor 16 drives the chuck 17 installed at its output end to rotate, and the chuck 17 drives the thread rolling sleeve 18 to rotate. As the slider 3 continues to advance, the steel bar is gradually inserted into the thread rolling sleeve 18, and the rotating thread rolling sleeve 18 mills the thread on the outer surface of the steel bar, thereby realizing the opening of threads on the surface of the steel bar. When the object sensor 8 detects the presence of the steel bar, the encoder 10 will monitor the rotation of the screw rod 5, and the processor 11 will calculate the distance that the slider 3 moves on the surface of the screw rod 5 according to the rotation of the screw rod 5, thereby controlling the movement distance of the slider 3, so that the processing length of the steel bar thread can be controlled and adjusted.
