Abstract

The invention belongs to the technical field of metal piece machining, and discloses a small-diameter and small-size chain ring manual bending tool which comprises a core bar and a handle. The radialsection of the core bar is elliptical. A groove is formed in the side wall of the core bar in the axial direction of the core bar. A first through hole running through the core bar in the radial direction is formed in the groove. The handle is fixed to the core bar. By means of the small-diameter and small-size chain ring manual bending tool, the efficient and high-quality manual bending machiningof a small-diameter and small-size chain ring can be realized.

Description

technical field [0001] The invention relates to the technical field of metal parts processing, in particular to a small-diameter and small-sized link manual bending tool and a forming method. Background technique [0002] Chain link products with small diameter and small size are often produced by manual bending when the required quantity is small. However, when processing by manual bending, it will face the problems of small part shape, high difficulty and low efficiency of manual high-precision bending. Contents of the invention [0003] The invention provides a small-diameter and small-size chain link manual bending tooling and a forming method, which solves the technical problems of high difficulty and low efficiency in the prior art of manually processing small-diameter and small-size chain links with high precision. [0004] In order to solve the above-mentioned technical problems, the present invention provides a small-diameter and small-sized link manual bending t...
