Description

Technical Field

[0001] The present application relates to the technical field of steel bar bending equipment, and in particular to a portable thin steel bar bender. Background Art

[0002] The diameter of thin steel bars is 6 to 10 mm, and the diameter of thick steel bars is usually greater than 22 mm. In current construction, there are many places where thin steel bars need to be bent. The steel bar bending machines available on the market can complete this task, but they are large in size and expensive, and it is not necessary to use commercially available steel bar bending machines to bend thin steel bars. The steel bar bending machines available on the market are inconvenient to move and cannot adapt to occasions with small spaces. Therefore, workers often use manual bending, which is difficult and may cause collapse and injury during the bending process; the bending angle is difficult to control, resulting in poor bending results. Therefore, there is an urgent need for a small, portable device to meet production needs.

[0003] Utility model patent announcement number CN220497595U discloses a steel bar bending device that can adjust the bending angle. It includes a support, a bending mechanism and a bending mechanism. A working chamber is provided on the right side of the support. The bending mechanism and the bending mechanism are located in the working chamber. A fixing groove and a pressing mechanism are provided on the top of the support. The fixing groove is connected to the working chamber. The bending mechanism includes a pressing handle and a pressing block. The left end of the pressing handle is hinged to the left end of the support. The pressing block is provided in the middle of the pressing handle. The bottom end of the pressing block is close to the right end of the fixing groove. The bending mechanism is located above the extension line of the fixing groove. The utility model is provided with a bending mechanism and a bending mechanism. The bending mechanism can determine the bending point and bend the steel bar, and then push the cylinder to bend it, thereby improving work efficiency. It is compact and easy to operate. Since thin steel bars usually have a small space when being bent and are directly wrapped around the installation object, it is difficult to bend the thin steel bars wrapped around the installation object using a bending device provided with a support. Summary of the Invention

[0004] In order to solve the problem that a bending device has difficulty in bending thin steel bars wrapped around an installation object, the present application provides a portable thin steel bar bender.

[0005] In the first aspect, the present application provides a portable thin steel bar bender adopting the following technical solutions:

[0006] A portable thin steel bar bender comprises a bending part, a rotating part and a handle; the bending part comprises a pressing piece, which is a groove capable of accommodating the thin steel bar, and is used to press the thin steel bar and enable the thin steel bar to pass through the bender; the rotating part is connected to the bending part, and the rotating part has an annular hollow structure, and the hollow structure has an opening, and the opening is used to hook a fixed rod into the hollow structure, and the rotating part can rotate relative to the fixed rod, and the thin steel bar is clamped between the pressing piece and the fixed rod; the handle is connected to the bending part, and the handle extends in a direction away from the hollow structure, allowing the user to rotate the bending part and the rotating part through the handle.

[0007] By adopting the above technical solution, when the thin steel bars are wrapped around an object, the object is usually a steel bar structure made of thick steel bars. The thick steel bars are used as fixed rods, the fixed rods are hooked by the rotating part, and the thin steel bars are passed through the grooves of the pressing plates, and the other side is against the fixed rods. By using the handle to rotate the bending part and the rotating part, the thin steel bars can be bent by the rotating movement of the pressing plates under the support of the thick steel bars, thereby completing the bending of the thin steel bars. The bender has a simple structure. By hooking the fixed rod and clamping the thin steel bars, the handle can be turned to complete the bending of the thin steel bars. The operation is convenient, and the thin steel bars can be bent on the steel bar structure. The usage scenarios are more diverse. Even if the bending is not on the steel bar structure, it can be performed by simply using a round and hard fixed rod.

[0008] Optionally, there are two rotating parts, which are symmetrically arranged on both sides of the bending part, and the openings of the rotating parts are oriented in the same direction.

[0009] By adopting the above technical solution, the two rotating parts symmetrically arranged on both sides of the bending part can make the force on the bender more uniform when rotating. While ensuring that there will be no deviation when bending thin steel bars, the stable bender makes it easier for the operator to exert force, thereby making the bending of thin steel bars more accurate and quick.

[0010] Optionally, the gap between the rotating parts is larger than the size of the groove.

[0011] By adopting the above technical solution, although the groove can allow thin steel bars to pass through, in actual operation, due to the long length of the thin steel bars, operation is more inconvenient. Therefore, by making the gap between the rotating parts larger than the size of the groove, the thin steel wire can be inserted into the groove of the pressing plate from between the rotating parts, which is convenient to use.

[0012] Optionally, one end of the hollow structure away from the bent portion is arc-shaped, so that the rotating portion can easily rotate relative to the fixed rod.

[0013] By adopting the above technical solution, during the rotation of the bending part, since the upper end will support the thin steel bar, the end of the hollow structure away from the bending part is the part that mainly contacts the fixed rod. Therefore, by setting the end away from the bending part to an arc shape, the relative rotation between the rotating part and the fixed rod can be better achieved.

[0014] Optionally, the axial direction of the groove of the pressing sheet is perpendicular to the axial direction of the hollow structure.

[0015] By adopting the above technical solution, the hollow structure is used to hook the fixing rod, and its axial direction is the extension direction of the fixing rod, and the axial direction of the groove is the extension direction of the thin steel bar. Therefore, the axial direction of the groove is perpendicular to the axial direction of the hollow structure, so that the thin steel bar can be bent in a direction perpendicular to the fixing rod, making the bending more neat and the direction easy to control.

[0016] Optionally, the pressing piece is arranged at an edge of the bent portion away from the opening.

[0017] By adopting the above technical solution, since the rotating part needs to fasten the fixing rod when bending, the rotation direction of the rotating part is away from the opening to prevent the fixing rod from falling out of the opening. When rotating in this direction, the edge of the bending part away from the opening first contacts the thin steel bar. By arranging the pressing piece at the edge that contacts the thin steel bar first, the bending force generated by the rotary bender can better act on the thin steel bar, thereby making the bender more labor-saving and convenient.

[0018] Optionally, the handle is provided with friction patterns.

[0019] By adopting the above technical solution, the handle is the force-generating structure of the bender for rotating and bending the thin steel wire. The user rotates the bender by using the handle. Therefore, by providing the friction grooves, the user can exert force better and control the bender more accurately, which is conducive to the efficient use of the bender.

[0020] Optionally, the friction lines are spiral lines.

[0021] By adopting the above technical solution, since the sliding direction of the handle is mainly the extension direction of the handle, the spiral pattern can increase the friction of the handle relative to the extension direction, which is conducive to the stable use of the bender.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The bending machine has a simple structure. By hooking the fixed rod and clamping the thin steel bar, turning the handle, the thin steel bar can be bent. It is easy to operate and can bend thin steel bars on the steel structure. The use scenarios are more diverse and it has good applicability.

[0024] 2. The two rotating parts symmetrically arranged on both sides of the bending part can make the force on the bender more uniform when rotating. While ensuring that there will be no deviation when bending thin steel bars, the stable bender makes it easier for the operator to exert force, thereby making the thin steel bars bent more accurately and quickly. In addition, by making the gap between the rotating parts larger than the opening size of the groove, the thin steel wire can be inserted into the groove of the pressing plate from between the rotating parts, which is convenient for use.
