Punching die positioning mechanism and method thereof

Abstract

The invention provides a punching die positioning mechanism and a method thereof. The punching die positioning mechanism comprises a rack, conveying mechanisms, a positioning mechanism body, a bendingtype guide rail, a hollow rod, a telescopic hose and an air pump. The two conveying mechanisms are oppositely arranged on the rack. The two sides of a bottom plate in the positioning mechanism body are fixedly connected with the two conveying mechanisms correspondingly. The bottom plate is movably provided with sliding blocks, the bottom of each sliding block is fixedly provided with a containingframe, and lead screws and the sliding blocks are in threaded transmission. The end portion of each lead screw is fixedly sleeved with a small friction wheel. The bottom of a large friction wheel isin friction contact with the small friction wheels. The bending type guide rail is arranged on a linear guide rail, and the hollow rod is arranged in the bending type guide rail and makes contact withone containing frame. Sectional materials are positioned through a friction transmission form, the hollow rod synchronously moves along with the containing frames, sectional material positioning, conveying and unloading are achieved, and accordingly automatic machining is guaranteed.

Description

technical field [0001] The invention relates to the technical field of stamping manufacturing, in particular to a positioning mechanism of a stamping die and a method thereof. Background technique [0002] Stamping parts are formed by applying external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation, so as to obtain stamping parts of required shape and size. Stamping parts are mainly made of metal Or non-metallic sheet metal, with the help of the pressure of the press, through the stamping die stamping process, and the premise of stamping first needs accurate positioning, so the positioning of the profile to be processed directly affects the quality of the processed workpiece. [0003] The publication number is CN107824701B, which provides a rapid positioning device for stamping parts of stamping dies. It realizes the positioning of the workpiece through the synchronous movement of the slider. It needs to be taken ...

Problems solved by technology

[0003] The publication number is CN107824701B, which provides a rapid positioning device for stamping parts of stamping dies. It realizes the positioning of the workpiece through the synchronous movement of the slider. It needs to be taken manually, and the degree of automation is not high, so it is not suitable for continuous processing steps
