Conical surface segment mould processing method and segment mould

Abstract

The invention relates to the field of segment mould processing, in particular to a conical surface segment mould processing method and a segment mould. The segment mould comprises a machine body, a knife rest and a machine tool disc for fixing workpieces to be processed, wherein a knife rest moving frame and a disc moving frame are arranged on the machine body; the knife rest moving frame comprises a knife rest horizontal moving frame and a knife rest longitudinal moving frame; the knife rest horizontal moving frame is arranged on the knife rest longitudinal moving frame; the knife rest is arranged on the knife rest horizontal moving frame; the machine tool disc is arranged on the disc moving frame; the disc moving frame is parallel to an X axis; the knife rest and the knife rest horizontal moving frame are parallel to a Z axis and form a certain included angle with the horizontal direction; and the included angle is the same as a conical half-angle of the conical surface. According to the invention, the tilt angles of the inner and outer conical surfaces are guaranteed to be the same through a clamp and the method; and when a groove on the inner conical surface is milled by utilizing the method and the mould, the errors caused by clamping for multiple times and the errors in digital control programs are also avoided, and the precision of milling and processing the groove is guaranteed.

Description

technical field [0001] The invention relates to the field of active mold processing, in particular to a method for processing a conical surface active mold and an active mold. Background technique [0002] When using the existing machining technology to process the inner and outer conical surfaces, in order to make the inner and outer conical surfaces cooperate with each other, the inclination angles of the inner and outer conical surfaces should be as consistent as possible. Generally, CNC machining tools are used to process the inner and outer conical surfaces. program to ensure the inclination angle of the inner and outer conical surfaces. [0003] There are the following defects when using CNC machine tools: 1. There are certain errors in the CNC machining program itself. When using CNC machine tools to process the inner and outer conical surfaces, it is easy to cause the inclination angles of the inner and outer conical surfaces to be inconsistent.

[0003] There are the following defects when using CNC machine tools: 1. There are certain errors in the CNC machining program itself. When using CNC machine tools to process the inner and outer conical surfaces, it is easy to cause the inclination angles of the inner and outer conical surfaces to be inconsistent. When the error is too large, it will cause rework. Even the scrapping of workpieces
