[0004] However, the bending curvature of the flat steel bent in this way tends to be too large, which does not meet the quality requirements, and the labor consumption increases and the production efficiency is low. Utility Model Content

[0005] (I) The problem to be solved by the utility model is: how to efficiently bend flat steel with a bending curvature that meets quality requirements at a construction site.

[0006] (II) Technical solution

[0007] The utility model provides a portable flat steel bender, comprising a fixed support plate, a movable support plate, a limit plate and a rotating assembly;

[0008] The movable support plate is arranged on one side of the fixed support plate;

[0009] The limit plate is arranged on one side of the fixed support plate, and a gap is left between the limit plate and the fixed support plate for the flat steel to pass through;

[0010] The limiting plate has a first side, the first side is parallel to the fixed support plate and the movable support plate, and the distance from the first side to the plane where the fixed support plate is close to the limiting plate is equal to the distance from the first side to the plane where the movable support plate is close to the limiting plate;

[0011] The rotating assembly is arranged on one side of the fixed supporting plate, and is used for driving the movable supporting plate to rotate around the first side edge of the limiting plate.

[0012] According to an embodiment of the utility model, the rotating assembly includes a rotating shaft and an annular turntable, the rotating shaft is fixedly connected to one side of the fixed support plate, the annular turntable is rotatably connected to the rotating shaft, and the movable support plate is fixedly connected to the annular turntable;

[0013] The first side edge of the limiting plate is colinear with the axis of the rotating shaft.

[0014] According to an embodiment of the utility model, a side plate is fixedly connected to a side of the fixed support plate close to the rotating shaft, the rotating shaft is fixedly connected to the side plate, and the limiting plate is installed on one side of the side plate.

[0015] According to one embodiment of the utility model, the rotating assembly includes a handle and a pressure rod, the handle is fixedly connected to a side of the side plate away from the fixed support plate, the pressure rod is fixedly connected to the movable support plate, and the pressure rod is perpendicular to the movable support plate.

[0016] According to an embodiment of the utility model, an arc-shaped groove is formed on a side of the fixed support plate close to the handle, and the side wall of the handle is fixedly connected in the arc-shaped groove.

[0021] Beneficial effects of the utility model:

[0022] The flat steel is placed between the fixed support plate and the limiting plate. Since the distance from the first side edge to the plane where one side of the fixed support plate close to the limiting plate is equal to the distance from the first side edge to the plane where one side of the movable support plate close to the limiting plate is located, part of the side of the flat steel close to the fixed support plate is in contact with the fixed support plate, and the other part is in contact with the movable support plate. The movable support plate is driven to rotate around the first side edge of the limiting plate by the rotating assembly. The bent part of the side of the flat steel close to the limiting plate is supported by the first side edge of the limiting plate, and then the flat steel is bent with the cooperation of the movable support plate, the fixed support plate and the limiting plate. Since the bent part of the flat steel is in contact with the first side edge of the limiting plate when it is bent, it can be ensured that the bending curvature of the flat steel will not be too large. Since the bending is not performed by knocking, the surface flatness of the formed flat steel is higher, there will be no depressions on the surface, and it saves time and effort.

[0023] By using this bending machine, the production efficiency is high and the labor consumption is reduced. There is no need to rely on an operating table or other auxiliary facilities. One person can complete the work. On-site application can save 50% of the labor input.

[0031] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1-Figure 4 As shown, one embodiment of the utility model provides a portable flat steel bender, comprising a fixed support plate 1, a movable support plate 2, a limit plate 4 and a rotating assembly;

[0033] The movable support plate 2 is arranged on one side of the fixed support plate 1;

[0034] The limiting plate 4 is arranged on one side of the fixed support plate 1, and a gap is left between the limiting plate 4 and the fixed support plate 1 for the flat steel to pass through;

[0035] The limiting plate 4 has a first side 401, the first side 401 is parallel to the fixed support plate 1 and the movable support plate 2, and the distance from the first side 401 to the plane where the fixed support plate 1 is close to the limiting plate 4 is equal to the distance from the first side 401 to the plane where the movable support plate 2 is close to the limiting plate 4;

[0036] The rotating assembly is disposed on one side of the fixed support plate 1 , and is used to drive the movable support plate 2 to rotate around the first side edge 401 of the limiting plate 4 .

[0037] The flat steel is placed between the fixed support plate 1 and the limiting plate 4. Since the distance from the first side edge 401 to the plane where the fixed support plate 1 close to the limiting plate 4 is located is equal to the distance from the first side edge 401 to the plane where the movable support plate 2 close to the limiting plate 4 is located, therefore, part of the side of the flat steel close to the fixed support plate 1 is in contact with the fixed support plate 1, and the other part is in contact with the movable support plate 2. The movable support plate 2 is driven by the rotating assembly to rotate around the first side edge 401 of the limiting plate 4, and the bent part of the side of the flat steel close to the limiting plate 4 is supported by the first side edge 401 of the limiting plate 4, and then the flat steel is bent with the cooperation of the movable support plate 2, the fixed support plate 1 and the limiting plate 4. Since the bent part of the flat steel is in contact with the first side edge 401 of the limiting plate 4 when it is bent, it can be ensured that the bending curvature of the flat steel will not be too large. Since the bending is not performed by knocking, the surface flatness of the formed flat steel is higher, there will be no depression on the surface, and it is more time-saving and labor-saving.

[0038] By using this bending machine, the production efficiency is high and the labor consumption is reduced. There is no need to rely on an operating table or other auxiliary facilities. One person can complete the work. On-site application can save 50% of the labor input.

[0039] The bender weighs about 1.3kg and has specifications of 100mm×80mm×450mm (the width, thickness and length of the bender, respectively). It is light in weight, small in size, easy to carry and store, and can be used in construction sites. It is simple to use and can be used to bend flat steels below 60mm×6mm (the width and thickness of the flat steel, respectively).

[0040] like Figure 3 The portable flat steel bender shown is a viewing angle when the flat steel is ready to be placed in. At this time, the first side edge 401 is parallel to the fixed pallet 1 and the movable pallet 2, and the distance from the first side edge 401 to the plane where the fixed pallet 1 is close to the limiting plate 4 is equal to the distance from the first side edge 401 to the plane where the movable pallet 2 is close to the limiting plate 4, that is, the upper surface of the fixed pallet 1 and the upper surface of the movable pallet 2 are located in the same horizontal plane.

[0041] like Figure 2 As shown, according to an embodiment of the present utility model, the side surface of the limiting plate 4 close to the movable supporting plate 2 is an arc surface.

[0042] The first side edge 401 is a side edge on the arc surface, which is set as an arc surface. The small arc bending design will not cause physical yield damage to the flat steel.

[0043] Since the bending position of the flat steel may be changed according to actual needs, a scale label may be attached to the fixed support plate 1 to facilitate determination of the bending position of the flat steel.

[0044] like Figure 1 As shown, according to one embodiment of the utility model, the rotating assembly includes a rotating shaft 6 and an annular turntable 8, the rotating shaft 6 is fixedly connected to one side of the fixed support plate 1, the annular turntable 8 is rotatably connected to the rotating shaft 6, and the movable support plate 2 is fixedly connected to the annular turntable 8;

[0045] The first side edge 401 of the limiting plate 4 is colinear with the axis of the rotating shaft 6 .

[0046] The movable support plate 2 and the annular turntable 8 are connected by the provided annular turntable 8, so that the movable support plate 2 can always rotate around the rotating shaft 6 when rotating.

[0047] Preferably, the axis of the annular turntable 8 coincides with the axis of the rotating shaft 6. The rotating shaft 6 is composed of a cylinder, a screw and a block. The diameter of the block is larger than the diameter of the cylinder, and the diameter of the cylinder is larger than the diameter of the screw. A screw hole is provided on the side of the cylinder away from the fixed support plate 1. One end of the screw is screwed into the screw hole, and the other end of the screw is fixedly connected with a block. The radius of the block is larger than the inner diameter of the annular turntable 8, so that the block can limit the annular turntable 8 on the cylinder of the rotating shaft 6, so that the movable support plate 2 and the annular turntable 8 are easy to disassemble and assemble from the rotating shaft 6. The length of the annular turntable 8 is the same as the length of the rotating shaft 6, so that the annular turntable 8 can only rotate around the axis of the rotating shaft 6. During installation, the annular turntable 8 is first sleeved on the cylinder, and the screw is screwed into the screw hole and screwed into place.

[0048] Of course, in this embodiment, the rotating shaft 6 can also be screwed with the fixed support plate 1, and a screw block is installed at the end of the rotating shaft 6 away from the fixed support plate 1 to facilitate the screwing of the rotating shaft 6, and the annular turntable 8 is rotatably connected to the rotating shaft 6 through a bearing. Its purpose does not deviate from the design concept of the utility model, and therefore, it should belong to the protection scope of the utility model.

[0049] According to an embodiment of the utility model, a side plate 9 is fixedly connected to a side of the fixed support plate 1 close to the rotating shaft 6 , the rotating shaft 6 is fixedly connected to the side plate 9 , and the limiting plate 4 is installed on one side of the side plate 9 .

[0050] According to an embodiment of the utility model, a limiting pin 7 is fixedly connected to one side of the limiting plate 4 close to the side plate 9, a limiting hole is provided on one side of the side plate 9 close to the limiting plate 4, and the limiting pin 7 is interference fit with the limiting hole.

[0051] Preferably, a rubber ring is sleeved on the limiting pin 7, and an interference fit is achieved between the rubber ring and the limiting hole.

[0052] When one limit pin 7 is provided, the limit pin 7 is a rectangular pin, and the limit hole is a rectangular hole, which can not only achieve the installation effect, but also prevent the limit plate 4 from rotating, causing the flat steel to bend;

[0053] When two limiting pins 7 are provided, the limiting pins 7 can be of any shape, for example, a cylindrical pin, and the limiting hole is a cylindrical hole.

[0054] The limit plate 4 of different thicknesses can be quickly replaced according to the thickness of the flat steel, thereby changing the height from the limit plate 4 to the fixed support plate 1. The height from the limit plate 4 to the fixed support plate 1 can be adjusted to adapt to the bending of flat steel with a thickness of 6 mm and below, which is more practical.

[0055] Of course, in this embodiment, the limit plate 4 and the side plate 9 can also be fixed by bolts or welding, which does not deviate from the design concept of the present utility model and should therefore fall within the protection scope of the present utility model.

[0056] According to one embodiment of the utility model, the rotating assembly includes a handle 5 and a pressure rod 3, the handle 5 is fixedly connected to the side of the side plate 9 away from the fixed support plate 1, the pressure rod 3 is fixedly connected to the movable support plate 2, and the pressure rod 3 is perpendicular to the movable support plate 2.

[0057] There is a gap between the handle 5 and the annular turntable 8 , so that the handle 5 will not interfere with the rotation of the annular turntable 8 .

[0058] The pressure rod 3 is arranged perpendicular to the movable support plate 2 to make it easier to apply force. When the fixed support plate 1 is placed on a table or the ground, an angle is formed between the handle 5 and the horizontal plane, and the distance from one end of the handle 5 away from the fixed support plate 1 to the ground is higher than that of the other end. This design makes it easier for the workstation personnel to hold the handle 5.

[0059] The handle 5 and the pressure rod 3 are provided to facilitate the application of force. The longer the handle 5 and the pressure rod 3 are, the more labor is saved.

[0060] The end of the handle 5 away from the movable support plate 2 and the end of the pressure rod 3 away from the fixed support plate 1 are both covered with anti-skid sleeves to achieve an anti-skid effect. The ends are curved and are not easy to scratch the workers. They are highly safe and more convenient for workers to apply force.

[0061] The anti-slip cover can be made of plastic material, which has a longer service life and is cost-effective.

[0062] According to an embodiment of the utility model, an arc-shaped groove is formed on one side of the fixed support plate 1 close to the handle 5, and the side wall of the handle 5 is fixedly connected in the arc-shaped groove.

[0063] The arc groove can limit the position of the handle 5 before it is fixed to the fixed support plate 1, thereby ensuring that the position of the handle 5 relative to the fixed support plate 1 does not change when the handle 5 is fixed.

[0064] Of course, in this embodiment, the anti-slip effect can also be achieved by providing anti-slip grooves on the handle 5 and the pressure rod 3 .

[0065] According to an embodiment of the present invention, the first side edge 401 is located in a plane where a side of the fixed support plate 1 close to the movable support plate 2 is located.

[0066] When the flat steel is bent, the lower surface of the flat steel near the bending area can fit with the fixed support plate 1, and under the action of the fixed support plate 1, the curvature of the bending part is more precise.

[0067] According to one embodiment of the utility model, the upper surface of the fixed support plate 1 is parallel to the lower surface of the limiting plate 4, so that when the flat steel is bent, the upper and lower surfaces can fit with the fixed support plate 1 and the limiting plate 4, so as to better bend the flat steel.

[0068] Specifically, the flat steel is placed on the fixed support plate 1, and the bent part is placed on the movable support plate 2. The handle 5 is held with one hand, and the pressure rod 3 is held with the other hand, so that the pressure rod 3 drives the movable support plate 2 to rotate around the first side edge 401 of the limiting plate 4 (that is, the first side edge 401 of the limiting plate 4 is used as the axial support edge of the rotating shaft 6), and then the flat steel is bent.

[0069] In the description of the present invention, it should be noted that the terms "upper" and "lower" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0070] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the insides of two components.
