Technical Field

[0001] This utility model relates to the field of steel bar processing technology, specifically to a steel bar positioning device for a steel bar processing line. Background Technology

[0002] In the process of steel bar processing in construction, bridges, and other engineering projects, steel bar bending machines are often used to process the steel bars into components with specific shapes, such as... Figure 1 As shown, a steel bar 1 is bent into a rectangular frame 2, with hook-shaped structures 3 formed at both ends. In traditional processing methods, the positioning of the steel bar 1 on the bending machine mainly relies on manual operation. The side length of the rectangular frame 2 needs to be frequently measured during the bending process to adjust the bending position. Manual measurement and positioning are time-consuming and labor-intensive, requiring multiple machine stops for calibration for each steel bar 1, resulting in low production efficiency. Therefore, there is an urgent need to design a steel bar positioning device for steel bar processing lines that can achieve rapid positioning and accurate calibration. Utility Model Content

[0003] The main purpose of this utility model is to provide a rebar positioning device for a rebar processing line, so as to solve the problems of frequent measurement of the rectangular side length to adjust the bending position during the bending process in the existing technology, which is time-consuming and labor-intensive for manual measurement and positioning, and requires multiple machine stops for calibration for each rebar, resulting in low production efficiency.

[0004] To achieve the above objectives, this utility model provides a rebar positioning device for a rebar processing line, including a housing and a limiting plate. A vertical shaft is vertically rotated on the top of the housing, a pad is fixedly mounted on the vertical shaft, and a drive mechanism for rotating the shaft is connected to it. A bracket is fixedly mounted on the pad, and a baffle is fixedly mounted on the bracket. The gap between the baffle and the vertical shaft forms a bending space. The limiting plate is fixedly connected to the top wall of the housing and is located on one side of the baffle. The rebar positioning device for a rebar processing line also includes a positioning component.

[0005] The positioning assembly includes a pressure roller and a positioning plate. One end of the positioning plate is pressed under the pressure roller, and its bottom wall abuts against the top wall of the housing. The two ends of the pressure roller are detachably mounted with frames, and each frame is fixedly connected to the top wall of the housing.

[0006] The positioning plate has a first receiving groove and a second receiving groove arranged side by side along its length. A first positioning rod is fixed on the first receiving groove, and two second positioning rods are fixed on the second receiving groove.

[0007] Preferably, the bracket includes a first L-shaped plate and a crossbar, one end of the first L-shaped plate is fixedly connected to the pad, and the other end is fixedly connected to the baffle through the crossbar.

[0008] Preferably, it also includes a second L-shaped plate, one end of which is fixedly connected to the top wall of the housing, and the other end is detachably connected to the baffle. Multiple reinforcing ribs are fixed at the inner corner of the second L-shaped plate.

[0009] Preferably, a mounting base is fixed on one side of the second L-shaped plate, and a roller is vertically rotatable on the mounting base.

[0010] Preferably, both ends of the pressure roller are coaxially connected to the shaft;

[0011] Two frames are symmetrically arranged on both sides of the pressure roller. Each frame includes a third L-shaped plate and a pressing plate. One end of the third L-shaped plate is fixed to the top wall of the machine housing and is equipped with two threaded rods for fixing.

[0012] Each threaded rod is screwed to the first nut, and the other end of the third L-shaped plate has a vertical groove, through which the connecting shaft is set;

[0013] The pressing plate is slidably sleeved on the two threaded rods and is located between the first nut and the connecting shaft.

[0014] Preferably, the positioning component further includes a U-shaped plate, one side wall of which is fixedly connected to the top wall of the housing and located between the pressure roller and the pad, with one end of the positioning plate inserted into the opening of the U-shaped plate.

[0015] Preferably, one end of the first positioning rod and the two second positioning rods are circumferentially threaded, and two second nuts are screwed onto each threaded segment, with the positioning plate located between the two second nuts.

[0016] The beneficial effects of the above scheme are:

[0017] The straight section of the reinforcing bar to be processed is passed through the bending space between the vertical axis and the baffle. The end of the reinforcing bar extends above the positioning plate. The position of the reinforcing bar is adjusted so that its other end (tail end) is aligned with and abuts against the outer edge of the first positioning rod, completing the initial positioning. The drive mechanism is started, and the vertical axis drives the pad and bracket to rotate. The vertical axis continues to rotate to the preset angle, and the head end of the reinforcing bar is bent into a hook-shaped structure. The reinforcing bar with the bent head end is removed, and the vertical axis rotates in the opposite direction to return to the initial position. The reinforcing bar is placed back in the bending space so that one end is aligned with the first second positioning rod on the positioning plate. The vertical axis rotates 90°, and the baffle pushes the reinforcing bar to bend along the surface of the positioning plate, forming the first side of the rectangular frame. The vertical axis rotates in the opposite direction again to return to the initial position, and the position of the reinforcing bar is adjusted so that its head end is aligned with the second second positioning rod. The vertical axis rotates 90°, and the baffle pushes the reinforcing bar to bend, forming the second side of the rectangular frame. The above actions are repeated, and the reinforcing bar is positioned sequentially through the two second positioning rods to complete the bending of the third and fourth sides, finally forming a closed rectangular frame and a hook-shaped structure at the tail end. This structural setting further improves work efficiency and reduces labor costs. Attached Figure Description

A vertical shaft 30 is vertically mounted on the top of the housing 10, and a washer 31 is fixedly mounted on the vertical shaft 30. The vertical shaft 30 is connected to a drive mechanism (not shown) for rotating it. The drive mechanism adopts existing technology and will not be described in detail. The drive mechanism can be a motor, and the output shaft of the motor is coaxially connected to the vertical shaft 30. Figure 4 As shown, a bracket 32 ​​is fixed on the pad 31, and a baffle 33 is fixed on the bracket 32, as follows. Figure 4As shown, the gap between the baffle 33 and the vertical axis 30 forms a bending space 300. The bracket 32 ​​includes a first L-shaped plate 321 and a crossbar 322. One end of the first L-shaped plate 321 is fixedly connected to the pad 31, and the other end of the first L-shaped plate 321 is fixedly connected to the baffle 33 via the crossbar 322. The limiting plate 20 is fixedly connected to the top wall of the housing 10, and the limiting plate 20 is located on one side of the baffle 33. The rebar positioning device for the rebar processing line also includes a positioning assembly 40. The positioning assembly 40 includes a pressure roller 41 and a positioning plate 42. One end of the positioning plate 42 is pressed under the pressure roller 41, and the bottom wall of the positioning plate 42 abuts against the top wall of the housing 10.

The positioning plate 42 is located between the two second nuts 70. The positions of the first positioning rod 44 and the second positioning rods 45 are adjusted according to the side length of different rectangular frames 2.

[0027] like Figure 3 As shown, the straight segment of the steel bar 1 to be processed is passed through the bending space 300 between the vertical shaft 30 and the baffle 33. The end of the steel bar 1 extends above the positioning plate 42. The position of the steel bar 1 is adjusted so that its other end is aligned with and abuts against the outer edge of the first positioning rod 44, completing the initial positioning. The drive mechanism is started, and the vertical shaft 30 drives the pad 31 and the bracket 32 ​​to rotate. The vertical shaft 30 continues to rotate to the preset angle, and the first end of the steel bar 1 is bent into a hook-shaped structure 3. The steel bar 1 with the bent first end is taken out, and the vertical shaft 30 rotates in the opposite direction to reset to the initial position. The steel bar 1 is placed back in the bending space 300 so that one end is aligned with the first second positioning rod 45 on the positioning plate 42. The vertical shaft 30 rotates 90°, and the baffle 33 pushes the steel bar 1 to bend along the surface of the vertical shaft 30, forming the first side of the rectangular frame 2. The vertical axis 30 is rotated in the opposite direction to reset, and the position of the reinforcing bar 1 is adjusted so that its first end is aligned with the second positioning rod 45.
