Problems solved by technology

Since the processing is single-piece processing, the material utilization rate is low and the material cost is high; the side holes are processed after the inclined surface is processed, and the clamping and positioning are very inconvenient and inefficient due to the irregular shape and thin wall thickness.

Embodiment Construction

[0026] The technical solutions of the present invention are further described below, but the claimed scope is not limited to the description.

[0027] A processing method for scrap-shaped irregular parts, comprising the following steps:

[0028] S1. Blanking, use a precision shearing machine to cut the blank into a cuboid blank for blanking of the cuboid blank, according to the design size of the parts with a length of 80mm, a width of 35mm and a height of 20mm, and then increase the length, width and height of the blank by 3-4mm. unloading;

[0029] S2. Milling the six faces of the cuboid blank. When milling the six faces of the cuboid blank, first process the four sides in the length and width directions, and then process the two planes in the height direction of the blank, so that the length dimension of the cuboid blank is a scrap-shaped irregular part The sum of the design length and wall thickness; the height dimension of the cuboid blank is the sum of the design height...

Abstract

A method for processing irregular parts in the shape of a dustpan. The invention creatively makes a part blank into a pattern of processing two parts for layout, and uses a wire cutting process to cut the blank in the subsequent processing process to ensure The processing accuracy of the parts is improved, and at the same time, the gap is preset in the processing process, so that the wall thickness of the parts can meet the design requirements. Finally, the shell feature with the same wall thickness is formed by CNC machining cavity, and the waist hole, installation hole and other parts are processed. Structural features, can process such parts efficiently and conveniently, fast and convenient clamping and positioning, high material utilization rate, low cost, short cycle time, high production efficiency, especially in mass production.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing method of a pan-shaped irregular part. Background technique [0002] In the fields of aviation, aerospace, electronics, instrumentation, etc., in order to adapt to the limited installation space and the structural shape of electronic components, the installation structural parts are often designed into irregular shapes. Due to the irregular shape of the parts, the positioning of the clip during processing is inconvenient, and the production efficiency is low, which brings certain difficulties to mass production. [0003] like Figure 1-Figure 3 The irregular-shaped parts shown are in the shape of a pan, and all the wall thicknesses are 2mm after the shell is extracted. There are waist-shaped holes and mounting holes on the bottom and mounting holes on the side. The current processing method is to use sheet metal milling to process the incli...
