specific Embodiment approach 1

[0020] Specific implementation mode one: combine figure 1 Describe this embodiment, a kind of processing sector technology described in this embodiment, its specific processing technology is as follows:

[0021] Step 1, blanking and pressing;

[0022] Step 2. Draw the curved plane line, the inner hole arc line, draw the surface line at both ends of the arc section, draw multiple notch lines, each hole line and narrow groove line;

[0023] Step 3. Milling the curved plane;

[0024] Step 4. Cut the arc of the inner hole, the two ends of the arc, cut multiple gaps, cut each hole, and cut multiple narrow grooves;

[0025] Step 5, grinding quasi-plane;

[0026] In this specific embodiment, step 4 is used to cut the arc of the inner hole and the two ends of the arc section to ensure the chord length of the inner and outer arcs and reduce the process steps, thereby reducing the running time and the number of transfers and improving the processing efficiency.

specific Embodiment approach 2

[0027] Specific implementation mode two: combination figure 1 Describe this embodiment, this embodiment is a further limitation to the processing technology described in specific embodiment one, a kind of processing sector process described in this embodiment, the cutting method in the described step four is wire cutting;

[0028] In this specific embodiment, the wire cutting processing method is adopted, which can provide a small processing allowance; adopting this processing method can ensure dimensional accuracy, and the processing time is shortened, and the manufacturing cost invested is relatively low.

specific Embodiment approach 3

[0029] Specific implementation mode three: combination figure 1 Describe this embodiment, this embodiment is a further limitation on the processing technology described in the second specific embodiment, a kind of processing sector process described in this embodiment, the center line cutting equipment in the step four is slow wire cutting machine;

[0030] In this specific embodiment, the slow wire cutting machine is used, which can ensure a high surface roughness of the cutting surface of the part.

Abstract

The invention provides a fan-shaped section machining process, and relates to the field of a machining process. In order to solve the problems of an existing process that machining is performed in different work procedures, the machining work procedures are complicated; the transfer is complicated; the machining efficiency is low; meanwhile, during the notch machining, the standards are not unified; and the notch position movement often occurs, and the product quality is influenced. The process comprises the following steps of 1, performing blanking shape pressing; 2, drawing bent plane linesand inner hole circular arc lines, drawing two end surface lines of arc sections, and drawing a plurality of notch lines, each hole line and narrow groove lines; 3, precisely milling bent planes; 4, precisely cutting inner hole circular arcs and two end surfaces of the arc sections, precisely cutting a plurality of notches, precisely cutting each hole, and precisely cutting a plurality of narrow grooves; and 5, precisely grinding planes. The fan-shaped section machining process is applicable to the machining of fan-shaped sections.

Description

technical field [0001] The invention relates to the field of mechanical processing technology, in particular to a processing sector technology. Background technique [0002] At present, the traditional method of processing the fan-shaped section is, the first step is to cut the material and press the shape; the second step is to draw the curved plane line, the arc line of the inner hole, and draw the surface lines at both ends of the arc section; the third step is to mill the curved plane, Milling the arc of the inner hole and the two ends of the arc section; the fourth step, drawing multiple notches, each hole line and narrow groove line; the fifth step, milling and milling multiple notches; the sixth step, drilling each hole; Seventh step, milling multiple narrow grooves; eighth step, grinding quasi-plane. [0003] To sum up, after the existing process adopts the curved plane, the fan-shaped end face, multiple notches, drilling holes and narrow grooves are all processed i...
