Problems solved by technology
During the punching process, the position and angle of the punching hole are mostly controlled manually, resulting in errors in the position and angle of the valve hole after the punching is completed, which also results in a low precision of the rim valve punching.

The invention discloses a rim valve punching device, which relates to the technical field of rim processing, and solves the problem that rim valve punching precision in the prior art is low. Accordingto the technical scheme adopted by the invention, the key point is that the rim valve punching device comprises a workbench, a punching base fixedly connected to the top of the workbench, a supporting disc arranged on the workbench and positioned at one side of the punching base, a supporting plate arranged on the top of the supporting disc, a supporting table arranged at one side, close to the punching base, of the bottom of the supporting plate, a jacking hydraulic cylinder arranged at one side, away from the punching base, of the bottom of the supporting plate and hinged on the supportingdisc, and a clamping mechanism arranged on the top of the supporting plate for fixing a rim onto the supporting plate, wherein the jacking hydraulic cylinder pushes the supporting plate to rotate, sothat a rim on the supporting plate tilts until one punching side of the rim abuts against the punching base, and punching operation is performed through a punch. An angle of inclination and the position of a rim axis are positioned through a hydraulic cylinder and the punching base, so that the valve punching position and angle precision are improved.
Description
technical field [0001] The invention relates to the technical field of wheel rim processing, more specifically, it relates to a wheel rim valve punching device. Background technique [0002] The rim, commonly known as the rim, is a component that installs and supports the tire on the periphery of the wheel, and forms the wheel together with the spokes. The rim and the spokes can be integral permanent connections or detachable. [0003] During the processing of the rim, in order to facilitate the later pumping of the tire, a valve hole is usually opened on the rim for the air valve to pass through. When the valve hole is opened on the rim, most of them are punched with a punching machine. Holes, in the process of punching, mostly manually support the rim to control the axis of the rim to form a certain angle with the punching direction of the punching equipment, and then use the punch to punch from the inner side of the rim to the outer side. During the punching process, the...
