[0001] The utility model relates to a steel bar processing device, in particular to a steel bar double-arc bending device. Background Art

[0002] During construction, the steel bars need to be bent and then arranged. Currently, during construction on site, a completely manual method is used. Bending the steel bars is time-consuming and labor-intensive. When dealing with double-arc bending work, it is difficult to complete the operation manually.

[0003] In view of the above-mentioned defects, the designer actively carried out research and innovation in order to create a double-arc bending device for steel bars to make it more valuable for industrial use. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a steel bar double-arc bending device.

[0005] The utility model discloses a double-arc steel bar bending device, comprising a base in contact with a foundation, a vertical column installed on the base, a placing plate for placing steel bars in the middle of the column, a lifting and moving pressing plate at the top of the column, two protruding supporting blocks on the placing plate, and a pressing block pressed tightly against the upper edge of the steel bars at the lower end of the pressing plate.

[0006] This steel bar double-arc bending device places the steel bar to be bent on two support blocks, presses the outer side of the steel bar with a pressure block on the pressure plate, and moves the pressure block downward to complete the bending operation of the steel bar, forming a double-arc structure.

[0007] Furthermore, a middle block is provided in the middle of the placement plate, and the middle block is located between the two supporting blocks.

[0008] The middle block placed in the middle of the slab supports the steel bars to facilitate bending and forming.

[0009] Furthermore, the middle block and the supporting block are movably mounted on the mounting plate through shafts, and the outer rings of the middle block and the supporting block are provided with inwardly concave grooves.

[0010] The middle block and the supporting block are movable, which is convenient for transmitting the steel bars, and the concave structure is convenient for limiting the position of the steel bars.

[0011] Furthermore, a groove is provided in the middle of the lower end of the pressing plate for the middle block to pass through.

[0012] The grooves on the pressure plate allow the intermediate block to pass through without causing movement interference.

[0013] Furthermore, the outer ring of the pressing block has an inwardly concave groove, and is movably mounted on the pressing plate through an axis.

[0014] The grooves on the pressure block serve to assist in limiting the position of the steel bars, thereby preventing the steel bars from shifting when being bent.

[0015] Furthermore, four guide wheels are movably mounted on the placement plate through shafts, and the guide wheels are located on both sides of the pressure plate.

[0016] The outer side of the placement plate is moved and guided by guide wheels to avoid deflection during operation.

[0017] Furthermore, a first hydraulic cylinder is fixed to the top of the column, and the first hydraulic cylinder drives the pressure plate to move up and down.

[0018] The first hydraulic cylinder installed on the column is used to drive the pressing plate to move and complete the steel bar bending operation.

[0019] Furthermore, a horizontal plate is fixed on the column, and two ends of the horizontal plate are provided with support rods extending forward.

[0020] The horizontal plate installed on the column is used to install the support rod, which supports the two ends of the steel bar.

[0021] Furthermore, two identical second hydraulic cylinders are fixed to the rear side of the cross plate, and the second hydraulic cylinders are fixedly connected to the support rods.

[0022] The support rod is driven to move by the second hydraulic cylinder to push the bent steel bar outwards, making it easy to remove the bent steel bar.

[0023] Through the above scheme, the present invention has at least the following advantages: this double-arc steel bar bending device drives the pressure block at the lower end to press on the upper end of the steel bar through the pressure plate that can move up and down, and completes the bending of the steel bar through the drive of the first hydraulic cylinder. Then, driven by the second hydraulic cylinder, the bent steel bar can be quickly removed. Under the premise of ensuring safety, the steel bar bending work can be completed quickly.

[0030] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] See also Figure 1 The base 1 of the device is in contact with the foundation to support the entire device. The vertical column 2 on the base 1 is the main installation structure of the device. The two support blocks 5 in the middle of the placement plate 3 can be supported on the lower end of the steel bar. The pressing block 6 at the lower end of the pressing plate 4 is pressed tightly on the upper end of the steel bar. When the pressing plate 4 moves downward, the support block 5 and the pressing block 6 interact with each other to bend the steel bar into shape.

[0032] The middle block 7 in the middle of the placement plate 3 can also be supported on the lower end of the steel bar, and the same side pressure block 6 is located between the middle block 7 and one of the support blocks 5, so that when the pressure block 6 presses the steel bar, the steel bar is bent in a double arc.

[0033] The grooves on the outer circles of the middle block 7 and the support block 5 can be used in conjunction with steel bars to provide positioning for the steel bars. At the same time, the middle block 7 and the support block 5 are rotatable structures to facilitate the input of steel bars from the outer end.

[0034] The groove at the lower end of the pressing plate 4 can be used for the middle block 7 to pass through, so as to avoid the middle block 7 interfering with the pressing plate 4.

[0035] The pressing block 6 is also a rotatable structure and has grooves, which can limit the position of the steel bars. During the bending operation, the steel bars are deformed, and the rotating pressing block 6, the middle block 7 and the supporting block 5 can rotate accordingly to facilitate bending.

[0036] The guide wheels 8 on the placement plate 3 are clamped on both sides of the pressing plate 4 to provide guidance for the pressing plate 4 to move up and down.

[0037] See also Figure 2 The first hydraulic cylinder 9 fixed at the top of the column 2 provides power for the up and down movement of the pressing plate 3.

[0038] See also Figure 1 and Figure 3A horizontal plate 10 perpendicular to the column 2 is fixed on the column 2, and two support rods 11 are arranged on the horizontal plate 10, and the support rods 11 are used to provide support for both ends of the steel bar.

[0039] The cross plate 10 can be driven by the second hydraulic cylinder 12 to move up and down. After the steel bar is bent, the second hydraulic cylinder 12 drives the support rod 11 to move up, so that the bent steel bar can be removed.

[0040] The working principle of the utility model is as follows:

[0041] When this double-arc steel bar bending device is in use, the first hydraulic cylinder 9 first drives the pressure plate 4 to move upward, so that the lower edge of the pressure block 6 at its lower end is higher than the upper edge of the support block 5 and the middle block 7, and a gap is formed for the steel bar to pass through. After the steel bar is placed in place, the first hydraulic cylinder 9 is started to drive the pressure block 6 to move downward. The pressure block 6 is located between the support block 5 and the middle block 7. Under the action of pressure, the steel bar is bent into shape. The two ends of the formed steel bar are supported on the support rod 11. After the steel bar is bent, the second hydraulic cylinder 12 works to drive the support rod 11 to move upward, pushing the bent steel bar outward to facilitate material removal.

[0042] Repeat the operation to bend the steel bars cyclically.

[0043] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
