Description

Technical Field

[0001] This utility model relates to the technology and field of steel bar bending, and in particular to a steel bar positioning and bending device. Background Technology

[0002] With the gradual development of my country's economic construction, construction is in full swing across the country, with various residential buildings, office buildings, road projects and other projects under construction. However, whether at the construction sites of numerous projects or in steel bar production workshops, it is often necessary to bend large quantities of steel bars.

[0003] The rebar positioning and bending device is one of the rebar processing machines. The working mechanism is a horizontal working disc that rotates on a vertical axis. The rebar is placed on the disc, and the support pin is fixed on the machine tool. The center pin and the bending pin are mounted on the working disc. When the disc rotates, it bends the rebar. In order to bend rebar of various diameters, there are several holes on the working disc for inserting the bending pin. The center pin of different diameters can also be replaced accordingly.

[0004] In existing technology, when bending steel bars, workers hold the steel bars and place them on a bending machine for bending. Before bending, workers need to manually mark the positions where the steel bars need to be bent at fixed lengths and points. Then, the marked areas are placed at the position of the central pin shaft for bending. The number of steel bars required is large, and marking and positioning them one by one greatly increases the working time of the operators, which is time-consuming and labor-intensive, and greatly reduces the bending efficiency of steel bars.

Detailed Implementation

[0030] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Please refer to Figures 1 to 5 As shown, a rebar positioning and bending device of the present invention includes a base 6, a bending machine body 2, a conveying mechanism 3 and a positioning mechanism 1. The bending machine body is provided on the base 6, the conveying mechanism 3 is provided on one side of the base 6, and the positioning mechanism 1 is provided on the other side of the base 6.

[0032] The positioning mechanism 1 includes a first rotation drive 101, a screw 104, a slider 102, and a pressure sensing component 103. The other side of the base 6 is provided with a groove adapted to the slider 102. The lower part of the slider 102 is slidably connected to the groove. The upper part of the slider 102 is provided with the pressure sensing component 103. The screw 104 passes through the inside of the slider 102 and is rotatably connected to the base 6. The first rotation drive 101 is drivenly connected to the screw 104.

[0033] The working principle of this utility model is as follows: In actual production and use, when it is necessary to bend the steel bar 4, the first rotating drive component 101 is operated to drive the slider 102 to move through the screw 104, so that the distance from the center pin to the pressure sensing component 103 is the distance from the required bending position of the steel bar 4 to the head of the steel bar 4. Then, the steel bar 4 is inserted into the conveying mechanism 3 and the conveying mechanism 3 is operated to transport the steel bar 4 through the bending machine body 2. Then, it continues to move forward to the pressure sensing component 103. Then, the steel bar 4 presses and limits the pressure sensing component 103. At the same time, the conveying mechanism 3 stops transporting the steel bar 4. At this time, the required bending position of the steel bar 4 is located outside the center pin. Then, the bending machine body 2 is operated to bend the steel bar 4.

[0034] Furthermore, the pressure sensing component 103 includes a pressure plate 1033, a reset member 1032, and a sensing member 1031. The upper part of the slider 102 is provided with a mounting groove adapted to the sensing member 1031. The sensing member 1031 is installed inside the mounting groove. The pressure plate 1033 is connected to the sensing member 1031 through the reset member 1032.

[0035] As can be seen from the above description, when the conveying mechanism 3 conveys the reinforcing bar 4 to the pressure plate 1033, the reinforcing bar 4 presses against the pressure plate 1033. Then, the pressure plate 1033 transmits the pressure to the sensing element 1031 through the reset element 1032. Subsequently, the sensing element 1031 receives the information that the reinforcing bar 4 has arrived and causes the conveying mechanism 3 to stop conveying. Then, the bending machine body 2 is operated to bend the reinforcing bar 4. During the bending process, the reinforcing bar 4 slides to the outside of the pressure plate 1033. Then, the pressure of the pressure plate 1033 is released, and the reset element 1032 resets the pressure plate 1033.

[0036] Furthermore, the conveying mechanism 3 includes a frame 303, a height adjustment component, an upper conveying component, and a lower conveying component. The frame 303 is connected to one side of the base 6. The lower conveying component is provided at the lower part of the frame 303, and the upper conveying component is provided at the upper part of the frame 303. The height adjustment component is connected to the upper conveying component.

[0037] As can be seen from the above description, when it is necessary to transport the steel bar 4, the steel bar 4 can be passed between the upper conveying component and the lower conveying component. Then, the upper conveying component and the lower conveying component are operated simultaneously, so that the steel bar 4 moves towards the bending machine body 2 with the cooperation of the upper conveying component and the lower conveying component. This allows the steel bar 4 to enter the bending machine better, reduces the manual handling of the steel bar 4, and saves time and effort.

[0038] Furthermore, the height adjustment assembly includes a first linear drive 307, a first slide bar 301, and a lifting frame 306. The lifting frame 306 is slidably connected to the upper part of the frame 303 via the first slide bar 301. The first linear drive 307 is linearly driven connected to the upper part of the lifting frame 306. The upper conveying assembly is connected to the lower part of the lifting frame 306.

[0039] As can be seen from the above description, when it is necessary to transport steel bars 4 of different diameters, the first linear drive 307 can be operated, so that the first linear drive 307 drives the upper conveying component to rise and fall through the lifting frame 306, so that the distance between the upper conveying component and the lower conveying component can be adapted to the transport of steel bars 4, thereby improving the utilization rate of the device.

[0040] Furthermore, the upper conveying component and the lower conveying component have the same structure;

[0041] The upper conveying assembly includes a second rotation drive and a 305 conveying shaft 304. The conveying shaft 304 is rotatably connected to the lower part of the lifting frame 306, and the second rotation drive is drivenly connected to the conveying shaft 304.

[0042] As can be seen from the above description, when it is necessary to transport the steel bar 4, the steel bar 4 passes through the conveying shaft 304, and then the second rotation drive is operated at the same time, so that the second rotation drive drives the conveying shaft 304 to rotate, and the steel bar 4 is transported towards the bending machine body 2 with the cooperation of the conveying shaft 304.

[0043] Furthermore, it also includes an indicator component, which is provided on the side of the base 6 near the slider 102;

[0044] The indicating component includes a pointer 8 and a scale 7. One end of the pointer 8 is connected to the slider 102, and the other end of the pointer 8 is provided with a fingertip. The fingertip is arranged parallel to the pressure plate 1033, and the scale 7 is connected to the base 6.

[0045] As can be seen from the above description, when it is necessary to adjust the bending position of the reinforcing bar 4, the bending position of the reinforcing bar 4 can be adjusted by adjusting the distance between the pressure plate 1033 and the central pin, so that the reinforcing bar 4 can be transported to the required position for bending. In addition, during the adjustment process, the pointer 8 moves with the slider 102, so that the pointer 8 can point more clearly to the scale 7, allowing the operator to observe the distance from the head of the reinforcing bar 4 to the central pin more intuitively.

[0046] Furthermore, an auxiliary clamping mechanism 9 is provided on the side of the frame 303 near the bending machine body 2. The auxiliary clamping mechanism 9 includes two sets of abutment components. The abutment components are arranged opposite to each other on the frame 303. The abutment components include a second linear drive member 901, a second slide rod 902, and an abutment plate 903. The abutment plate 903 is slidably connected to the frame 303 through a plurality of second slide rods 902. One side of the second linear drive member 901 is connected to the frame 303, and the other side of the second linear drive member 901 is linearly driven connected to the abutment plate 903.

[0047] As described above, once the reinforcing bar 4 is positioned, the second linear drive component 901 on the two abutment components can be activated. This allows the second linear drive component 901 to move the abutment plate 903 towards the reinforcing bar 4, thus fixing the reinforcing bar 4 left and right with the cooperation of the two abutment plates 903. This prevents the reinforcing bar 4 from shifting when bending. Furthermore, the base 6 also includes several movable wheels 5, with a plurality of these wheels located on its lower part.

[0048] As can be seen from the above description, it facilitates the movement of the device more conveniently.

[0049] Furthermore, it also includes a PLC controller, which is electrically connected to the bending machine body 2, the conveying mechanism 3 and the positioning mechanism 1 respectively.

[0050] As can be seen from the above description, it is beneficial to adjust the parameters of the rebar bending machine through the PLC controller, and makes it more convenient for operators to operate the rebar bending machine.
