Workpiece with [-shaped structure inner frame and precise machining method thereof

Abstract

The invention provides a workpiece with a [-shaped structure inner frame and a precise machining method of the workpiece. The workpiece comprises a bottom surface, a first outer side face, an obverseside, a second outer side face, an edge corner, outer top surfaces, a first inner side face, a second inner side face and an inner top surface. The first outer side face and the second outer side faceare located on the two sides of the bottom surface, the edge corner is located between the first outer side face and the obverse side, and the outer top surfaces are located on the top of the first outer side face and the top of the second outer side face. The first inner side face and the second inner side face are located on the two sides of the inner top surface, the first inner side face andthe second outer side face correspond to each other, and the second inner side face and the first outer side face correspond to each other. The structure of the workpiece is arranged in a bilateral symmetry mode, the purpose of the machining precision of a precision-grade mold of the workpiece with a [-shaped structure can be achieved, and the problem that due to stress release, deformation of theworkpiece with the[-shaped structure inner frame happens in the machining process is solved.

Description

technical field [0001] The invention relates to a workpiece and a precision processing method thereof, in particular to a workpiece with a door-shaped inner frame and a precision processing method thereof. Background technique [0002] As we all know, a lot of heat will be generated during metal processing, and because of the different thermal conductivity of various metal elements in the die steel, eventually, these heat will accumulate near the processing, forming what we call stress, in During the subsequent cooling process, that is, during the stress release process, the two sides of the entire frame (marked 4 / 5) will be deflected inward or outward, resulting in deformation, resulting in inconsistent data at the upper and lower ends of the size, so Make the workpiece cannot be installed normally or the component cannot work normally. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide a workpiece...
