Embodiment Construction

[0023] like Figure 1 to Figure 3 The processing method of the band raised membrane-like tire shown adopts the following specific steps:

[0024] (1) Processing of bottom surface 1:

[0025] (1.1) Support the flat bottom surface on the machine tool, that is, the bottom surface is upward, and support the bottom surface in a state parallel to the machine tool surface;

[0026] (1.2) Roughly plan the bottom surface;

[0027] (1.3) Finely plan the bottom surface to ensure that the flatness is 0.1-0.2mm;

[0028] (2) CNC machining of profile 2:

[0029] (2.1) Make the leading lines a and b first, such as Figure 4 As shown, then use the Contour-driven command in CATIA V5, the guide lines a and b divide the main profile into three parts, and each part is subjected to rough machining, semi-finishing machining and finishing machining respectively;

[0030] (2.2) Carry out rough machining of the profile, leaving a margin of 0.7-0.9mm;

[0031] (2.3) Carry out semi-finishing of th...

Abstract

The invention provides a machining method for a mold with a protrusion. The machining method includes the following concrete steps of bottom surface machining, profile numerical control machining, polishing by a bench worker, and delivering and inspecting. According to the profile numerical control machining, guiding lines need to be firstly made, then the Contour-driven command in CATIA V5 is used, the guiding lines divide a main profile into three parts, rough machining, semi-finish machining and finish machining are performed on each part, and after profile machining is completed, whether step machining is performed or not is determined according to the remaining quantity of a step surface; in layering machining, a Profile Contouring command in CATIA V5 is used for layering machining through an end mill, for example, horizontal layering or vertical layering is performed or horizontal layering and vertical layering are performed at the same time, and the non-working surface of the step is in flush joint through the end mill. By the adoption of the machining method, the machining problems of the mold with the protrusion can be effectively solved, machining time is shortened, and the geometric accuracy of the mold is effectively guaranteed.

Description

technical field [0001] The invention relates to a method for processing a membrane-like tire with protrusions, and belongs to the technical field of mechanical processing. Background technique [0002] like figure 1 As shown, this type of membrane tire is generally a casting, and there is often a large protrusion in the middle. Larger corrugations and even overcuts appear, so it is difficult to achieve the required geometric shape and geometric size. Contents of the invention [0003] Aiming at the above deficiencies, the present invention provides a method for processing a membrane-like tire with protrusions. [0004] Technical scheme of the present invention: the processing method of band-protruded membrane-like tire adopts the following specific steps: [0005] (1) Processing of the bottom surface: [0006] (1.1) Support the flat bottom surface on the machine tool, that is, the bottom surface is upward, and support the bottom surface in a state parallel to the machi...
