Description

Technical Field

[0001] The utility model relates to the technical field of tool production equipment, in particular to a bending knife with a rotation avoidance function. Background Art

[0002] Bending tools are often needed during machining operations to bend the original sheet materials, such as bending the edges of some original sheets.

[0003] For example, patent document CN211637990U discloses a bending tool and a bending machine, wherein the bending tool is used to bend a bending part, and the bending part has a protruding structure. The bending tool includes: a first tool body and a second tool body, wherein the second tool body is detachably connected to the first tool body, and the second tool body is arranged corresponding to the protruding structure. After the bending of the bending part is completed, the first tool body can be withdrawn by following the vertical upward movement of the bending machine without damaging the bending part, and the second tool body is separated from the first tool body due to demagnetization or being held by the protruding structure of the bending part, and then the second tool body can be manually taken out, thereby effectively ensuring that both the first tool body and the second tool body can be withdrawn smoothly, perfectly realizing the protection of the bending angle, and ensuring the beautiful appearance and product quality of the bending part.

[0004] For example, when the bending tool mentioned above is used to bend a plate, if there is a raised structure on the plate that needs to be avoided, the bending tool needs to manually remove the second tool body, which involves complicated disassembly and assembly operations. This has low bending efficiency and is labor-intensive, so improvements need to be made. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a bending knife with a rotation avoidance function in view of the defects existing in the above-mentioned prior art. Its main purpose is to design a combination of a pulling component and a second knife body. When avoidance is required, the pulling component drives the second knife body to rotate and avoid the position relative to the original plate, thereby facilitating the bending operation.

[0006] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0007] A bending knife with a rotation avoidance function, comprising: a mounting seat, a first knife body, a second knife body and a pulling assembly;

[0008] A first blade body, wherein the first blade body is disposed on a mounting seat;

[0009] A second blade body, hinged to the mounting seat;

[0010] A pulling assembly is arranged on the mounting seat and is used for driving the second blade body to rotate and avoid position.

[0011] By designing the combination of the pulling component and the second knife body, when avoidance is required, the pulling component drives the second knife body to rotate and avoid the position relative to the original plate, which is convenient for bending operation.

[0012] Furthermore, the pulling assembly includes a cylinder arranged on the mounting seat, a piston rod connected to the cylinder, and a pull rod hinged to one end of the piston rod away from the cylinder; the end of the pull rod away from the piston rod is hinged to one side of the second blade body.

[0013] Furthermore, the blades of the first blade body and the second blade body are both in an "L" shape.

[0014] Furthermore, the mounting seat is provided with a mounting groove, and the mounting groove is used to be plugged and matched with the mounting step of the device to be installed.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model combines the pulling component with the second knife body by design. When avoidance is required, the pulling component drives the second knife body to rotate and avoid the position relative to the original plate, which is convenient for bending operation.

[0017] 2. The utility model does not need to manually remove the second knife body when the knife is withdrawn after the plate is bent, which can reduce labor costs and make the operation safer.

[0018] 3. The utility model increases the bending depth of the first knife body and the second knife body by setting the blades of the first knife body and the second knife body to be "L"-shaped, ensuring that the first knife body and the second knife body can be processed in place at one time, thereby improving the bending efficiency.
