Description

Technical Field

[0001] The utility model specifically relates to the technical field of turnover machines, and particularly relates to a simple turnover machine for stainless steel round bars. Background Technique

[0002] Stainless steel bars can be divided into three types according to the production process: hot rolling, forging and cold drawing. The specifications of hot-rolled stainless steel round bars are 5.5 - 250 mm. Among them: small stainless steel round bars of 5.5 - 25 mm are mostly supplied in bundles of straight bars and are commonly used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25 mm are mainly used to manufacture mechanical parts or as seamless steel pipe blanks. When processing both ends of the bars, turning is required.

[0003] Chinese Utility Model Publication No. CN 214880054 U discloses a special automatic hydraulic turnover tooling for bars, including a base and a turnover frame. The turnover frame is hinged to the base, and a turnover oil cylinder is hinged between the base and the turnover frame; the turnover frame is used to fix the bars and includes a bottom plate frame and a pressing plate frame. An arc plate for clamping the bar parts is provided on the bottom plate frame; the pressing plate frame is hinged to the bottom plate frame, and a pressing oil cylinder is hinged between the pressing plate frame and the bottom plate frame. The pressing plate frame is used to press the bar parts forward;

[0004] For the above-mentioned special automatic hydraulic turnover tooling for bars, when the pressing oil cylinder contracts, the pressing plate frame flips to one side of the bottom plate frame, so that the turnover frame forms a closed structure; when the lifting oil cylinder extends, the arc plate moves upward to tightly hold the bar, completing the fixation of the bar; when the turnover oil cylinder extends, the turnover frame flips from the horizontal state to the vertical state, completing the turnover of the bar. However, when one end of the processing equipment cannot be changed, a 360-degree turnover is required to process both ends of the bar. It is not convenient to process from horizontal to vertical, and it is more troublesome to use. Therefore, we provide a simple turnover machine for stainless steel round bars. By driving the bar to rotate with a rotating frame, the angle can be adjusted arbitrarily, and bars with different diameters and lengths can be driven to rotate, which is more convenient to use and effectively makes up for the above problems.
