Description

Technical Field

[0001] The utility model relates to the technical field of frame bending, in particular to a bending handle of a template frame. Background Art

[0002] In civil engineering, a frame is a structural system formed by rigidly connecting components such as beams and columns. When the frame is produced, the metal material is bent to achieve the specific angle and shape required in the design, so that the bent metal material is connected end to end to form a frame.

[0003] However, it still has the following disadvantages in actual use:

[0004] When bending the existing frame, the metal material needs to be clamped and then bent manually through the bending handle. However, when the existing bending handle is used to bend metal materials of different heights, the height of the bending part cannot be adjusted. When bending higher metal materials, it is easy to cause uneven force, causing the shape of the bent part of the metal material to be inconsistent with the expectation. In severe cases, the bent part of the metal material may be dented or deformed. Utility Model Content

[0005] The purpose of the utility model is to provide a bending handle for a template frame to solve the problem raised in the above-mentioned background technology that the existing bending handle cannot adjust the height of the bending part when bending metal materials of different heights, and it is easy to cause uneven force when bending higher metal materials, so that the shape of the bending part of the metal material does not meet the expectation, and in severe cases, it causes the bending part of the metal material to be dented or deformed.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a bending handle of a template frame, comprising:

[0008] The main body mechanism comprises a workbench, the outer wall of the workbench is fixedly connected to a support frame, the top of the support frame is fixedly connected to a connecting frame, one side of the top of the support frame is fixedly connected to a fixed frame, and the other side is slidably connected to a movable frame;

[0012] Furthermore, the end of the connecting spring is movably connected to a driven plate, the outer wall of the driven plate is fixedly connected to a pushing frame, a corresponding hole is penetrated through the outer wall of the fixed cylinder, and a limiting ball is movably connected in the corresponding hole;

[0013] Furthermore, it also includes a handle mechanism, wherein the handle of the handle mechanism is slidably connected to a sliding frame on the circumferential outer wall of the support frame, the outer wall of the support frame is provided with a mounting groove, an annular spring is movably connected in the mounting groove, the annular spring is fixedly connected to the outer wall of the sliding frame, and a fixing rod is fixedly connected to the outer wall on one side of the top of the sliding frame;

[0014] Furthermore, a handle cover is threadedly connected to the outer circumferential wall of the fixing rod, a cushion is fixedly connected to the outer circumferential wall of the handle cover, and a positioning cylinder is fixedly connected to the other side of the outer wall at the top of the sliding frame;

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. According to the utility model, when metal materials of different heights just penetrate between the fixed frame and the movable frame, they contact the telescopic rotating plate, and the metal materials continue to move to push the telescopic rotating plate upward.
