Method for treating burrs of fine components in batches

Abstract

The invention relates to the technical field of machining, in particular to a method for treating burrs of fine components in batches. The method comprises the following steps of step 1, preparing materials by cutting and machining through an electric discharge machining wire, and machining component rough blanks; step 2, performing grinding ultra-precision machining on the component rough blanksobtained in the step 1 through a grinding machine, so that right angles are machined on the component rough blanks; step 3, slotting a grinding body according to a PH value, and cutting out the thickness of a single piece in a manner of slotting the periphery of a main body material, and maintaining the allowance of 0.005 to 0.010 mm on each side; step 4, dividing the main body with 18 pieces of amain body material into a main body with 6 pieces, namely, the main body material is averagely divided into three main bodies; step 5, simultaneously machining the 6 pieces on the main body by adopting EDM; step 6, performing comprehensive quality detection on the machined main bodies; step 7, grinding and slicing according to the cut out thickness of the main bodies, and making each piece levelprecisely in a grinding manner; step 8, treating the burrs of other edges; and step 9, performing quality detection and delivery again.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for batch processing burrs of small parts. Background technique [0002] At present, the requirements for precision electronic connector products are constantly improving, and the products require zero defects. Therefore, the processing accuracy of batch mold parts is required to be zero missing. The existing processing technology is assembled with a set of 200PCS small parts. When these parts are processed by various processes At the same time, the burrs generated during the whole process of processing are repeatedly processed on the oil stone, which will cause the edges and corners of the shape to collapse and the plane to be uneven. During processing, due to the small area of ​​the bottom of the part, there is a risk that the entire surface will be pushed down on the oilstone when processing burrs, resulting in inconsistent clamping when processing FG; p...

[0002] At present, the requirements for precision electronic connector products are constantly improving, and the products require zero defects. Therefore, the processing accuracy of batch mold parts is required to be zero missing. The existing processing technology is assembled with a set of 200PCS small parts. When these parts are processed by various processes During the whole process, the burrs generated during processing are repeatedly processed on the oil stone, which will cause the edges and corners of the shape to collapse and the plane to be uneven.

During processing, due to the small area of ​​the bottom of the part, there is a risk that the entire surface will be pushed down on the oilstone when processing burrs, resulting in inconsistent clamping when processing FG; processing takes a long time, and it takes 200 pieces to count. It takes 12 hours to deal with the burrs, the processing efficiency is low, and the flatness and size of the products produced by the mold set cannot meet the requirements. After analyzing the reasons and checking the single part, there is no obvious problem, which brings a lot of trouble to the process improvement and finding the problem points.
