Problems solved by technology

[0002] During the hole turning process, the material to be turned will elongate in the circumferential direction and cause its thickness to decrease. Since the gap between the hole turning punch and die is double the thickness of the material, when the thickness of the hole turning material is reduced, the hole turning punch and die and The material cannot fit well, resulting in a certain gap, causing the hole to be curled and not straight. The conventional solution is to make the gap of the hole as a whole smaller, but this will increase the force of the hole and shorten the life of the mold. It also makes the entire hole-turning part too thin, reducing the strength of the hole-turning part

Embodiment Construction

[0026] Present embodiment is CAD platform with UG software, uses VS2015 (internal compiler is Microsoft Visualstudio 2010) integrated environment, under Windows operating system, UG function and NXOpenC++ library are compiled and generated DLL (dynamic link library) by VS2015, for UG After the software is called, the codes for controlling the machining of the CNC machine tool are generated and input into the CNC machine tool to control the machining of the CNC machine tool. Among the above, the full name of UG software is Unigraphics NX, which is an interactive CAD / CAM / CAE / PDM (computer-aided design, aided manufacturing, aided Engineering, product data management) software system, which is often used in the design, processing, simulation and NC code generation of hardware parts, where the NC code can be input into the CNC machine tool to control it for part processing.

[0027] The 3D drawings referred to in this embodiment are all standard 3D drawings in the hardware manufact...

Abstract

The invention relates to the field of machine tool machining, in particular to a hole flanging female die, a manufacturing method thereof, a storage medium and a CNC machine tool. The method comprisesthe steps: reading a 3D graph of the hole flanging female die; defining the opening direction of a concave hole for hole flanging on the hole flanging concave die as the vertical direction, and obtaining the concave hole specified by an engineer on the 3D graph, the material thickness t0 of the concave hole, the diameter D of a hole flanging punch, the radius r of a hole flanging inner angle, thediameter d of a pre-punched hole and the height h of a hole flanging straight body; according to the material thickness t0, the hole flanging punch diameter D, the hole flanging inner angle radius r,the pre-punching hole diameter d and the hole flanging straight body height h, calculating a mold pulling angle x required by the specified concave hole, and closing the bottom edge of the side wallsurface of the specified concave hole inwards until an included angle formed by the side wall surface and the vertical direction reaches the mold pulling angle x; and converting the 3D graph after concave hole correction into an NC code, and transmitting the NC code to an external CNC machine tool for processing. The problem that hole flanging is not straight is solved, and the mold repairing costis reduced.

Description

technical field [0001] The invention relates to the field of machine tool processing, in particular to a boring die and its manufacturing method, a storage medium and a CNC machine tool, wherein a computer program is stored in the storage medium, and the program can be executed by a processor of the CNC machine tool to realize the method. Background technique [0002] During the hole turning process, the material to be turned will elongate in the circumferential direction and cause its thickness to decrease. Since the gap between the hole turning punch and die is double the thickness of the material, when the thickness of the hole turning material is reduced, the hole turning punch and die and The material cannot fit well, resulting in a certain gap, causing the hole to be curled and not straight. The conventional solution is to make the gap of the hole as a whole smaller, but this will increase the force of the hole and shorten the life of the mold. It also makes the entire...
