Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and in particular to tooling suitable for bending flat iron. Background Technology

[0002] Flat steel, also known as flat bar, is a long strip of steel with a large width-to-thickness ratio and aspect ratio. It is usually rectangular in cross-section and is widely used in technical fields such as construction, machinery manufacturing, power engineering, and railway engineering.

[0003] During use, the shape of flat iron often needs to be processed to adapt to different application scenarios; for example, the straight and long flat iron can be processed into an arc shape with a certain curvature (such as "U"), or the straight and long flat iron can be processed into an angle shape with a certain angle (such as "L").

[0004] Currently, the most common methods for processing flat iron are: 1. Bending the straight, long flat iron manually. This method is simple and direct, but the flat iron is prone to springing back during bending, posing a safety hazard. 2. Bending the flat iron using a bending machine. While this method eliminates manual operation, its structure is complex, and its manufacturing and maintenance costs are high, making it unsuitable for the general public. 3. Cutting the straight, long flat iron at an appropriate location and then welding the two ends together to form the desired shape. However, this method not only compromises the integrity of the flat iron, leading to reduced structural strength and corrosion resistance (high-temperature welding damages the anti-corrosion galvanized layer), but also results in redundant processing steps (e.g., processing an "L" shape requires one cut and two welds, while processing a "U" shape requires two cuts and four welds), reducing processing efficiency.

[0039] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0040] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] like Figures 1-3 As shown, this utility model embodiment provides a tooling suitable for bending flat iron, mainly including: a base 1, a first fixing column 2, a second fixing column 3, a support 4, and a limiting member 5, etc.

[0042] The base 1 has a first fixing post 2 and a second fixing post 3 spaced apart, both located on the same plane. The first fixing post 2 can contact one side wall of the flat iron 6, and the second fixing post 3 can contact the other side wall of the flat iron 6. The first fixing post 2 is configured as a fixed force-bearing point, and the second fixing post 3 is configured as another fixed force-bearing point. The support base 4 is rotatably mounted on the second fixing post 3, and the flat iron 6 is placed on it. The limiting member 5 is mounted on the support base 4 and rotates with the rotation of the support base 4, contacting the flat iron 6. The limiting member 5 is configured as a movable force-bearing point.

[0043] First, the flat iron 6 is placed on the support base 4, so that one side wall of the flat iron 6 contacts the first fixed post 2 and the other side wall contacts the second fixed post 3. A force perpendicular to the axis of the support base 4 is applied to the support base 4, thereby generating a torque that drives the support base 4 to rotate. The rotating support base 4 drives the limiting member 5 to rotate until the limiting member 5 contacts the flat iron 6. The support base 4 continues to rotate. Under the combined action of the first fixed post 2, the second fixed post 3 and the limiting member 5, the flat iron 6 is bent to form a flat iron 6 without breaks and with a curved arc.

[0044] Specifically, such as Figure 1 As shown, the first fixing post 2 is fixedly mounted on the top of the base 1, and has a receiving groove 21 for accommodating the flat iron 6. The receiving groove 21 can be a plurality of annular grooves spaced apart along the axial direction of the first fixing post 2, or a spiral groove extending along the axial direction of the first fixing post 2, or a combination of annular grooves and spiral grooves. The receiving groove 21 is used to position the flat iron 6 and prevent the flat iron 6 from moving along the axis of the first fixing post 2.

[0045] Furthermore, in this embodiment, the first fixing column 2 is made of hot work die steel, such as H13 (4Cr5MoSiV1) or 3Cr2W8V.

[0046] The second fixed column 3 includes a threaded section at the top and a smooth section at the bottom. The smooth section is rotatably connected to the support base 4, and the threaded section is fitted with a nut 8, which abuts against the support base 4 to prevent the support base 4 from moving along the axis of the second fixed column 3 during rotation.

[0047] Furthermore, in this embodiment, the second fixing column 3 is made of hot-work die steel, such as H13 (4Cr5MoSiV1) or 3Cr2W8V.

[0048] like Figure 2 As shown, the support base 4 mainly includes several parts such as the support body 41 and the positioning component 42.

[0049] The support body 41 is rotatably fitted onto the smooth rod section of the second fixed post 3. The positioning member 42 is rotatably fitted onto the smooth rod section of the second fixed post 3, located above the support body 41, approximately 3-8 mm away from the support body 41.

[0050] Furthermore, the support base 4 also includes: a first connecting post 43 disposed in the radial direction of the support body 41, and a second connecting post 44 disposed in the radial direction of the positioning member 42 corresponding to the first connecting post 43, and the first connecting post 43 and the second connecting post 44 are connected by a third connecting post 45.

[0051] The limiting member 5 is provided on the first connecting post 43 and the second connecting post 44. It can be a columnar structure or a frame structure with a cavity 52.

[0052] Specifically, such as Figure 2 As shown, when the limiting member 5 is a columnar structure, the limiting member 5 is welded between the first connecting post 43 and the second connecting post 44 and on the side adjacent to the flat iron 6 to improve the stress strength of the limiting member 5.

[0053] like Figure 3 As shown, when the limiting member 5 is a frame structure with a cavity 52, the limiting member 5 is detachably sleeved on the first connecting post 43 and the second connecting post 44, and the cavity 52 wall of the limiting member 5 is attached to the outer wall surface of the first connecting post 43 and the second connecting post 44.

[0054] Specifically, such as Figure 3 As shown, the limiting member 5 has two threaded holes 51 arranged opposite each other. The limiting member 5 is sleeved on the first connecting post 43 and the second connecting post 44, and then the limiting member 5 is detachably connected to the first connecting post 43 and the second connecting post 44 by bolts. By setting the limiting member 5 as a detachable structure, the bending arc of the flat iron 6 can be adjusted by changing the distance between the limiting member 5 and the second fixed post 3.

[0055] Furthermore, to save time and effort when rotating the support 4, the tooling in this embodiment also includes a handle 7, which is fixedly mounted on the third connecting column 45.

[0056] In use, first place the flat iron 6 between the support body 41 and the positioning member 42, so that one side of the flat iron 6 is placed in the receiving groove 21 and the other side is in contact with the second fixing post 3. Then apply a rotational force to the handle 7 to make the support base 4 rotate. The rotating support base 4 drives the limiting member 5 to rotate synchronously until the limiting member 5 contacts the flat iron 6. Continue to apply a rotational force to the handle 7. During the rotation, the first fixing post 2, the second fixing post 3 and the limiting member 5 work together to bend the flat iron 6 to form a flat iron 6 without breaks and with a curved arc.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
