Abstract

The invention discloses a small hole rapid molding process which comprises the following steps of: A. assembling a mould and installing with a material; B. punching a guide hole; C. grading; D. punching small holes; E. punching a small hole set; and F. sequentially circulating and repeating the step B, the step C and the step D until punching and cutting with the material for a metal to be processed is finished. When small hole processing is carried out by adopting the small hole rapid molding process, the mould is installed in a high-speed punch, working with more than 500 punching times perminute is carried out on the high-speed punch, and a product is once stamped and molded without needing secondary processing. The process has high production efficiency and low cost. Meanwhile, the invention also has the following characteristics that: the punching head of a convex mould is not easily broken and has long service life in the high-speed punching process.

Description

technical field [0001] The invention relates to the technical field of electronic device manufacturing, in particular to a small hole rapid prototyping process. Background technique [0002] At present, in the production process of multiple small holes with small spacing between holes, three processes can be used to achieve: 1) single-process die stamping forming process: use multiple sets of single-process dies to stamp the small holes, and then use a pair of single-process dies to form small holes. 2) Laser etching process: First, use a single-process mold or other molds to manufacture the required products into semi-finished products, and then use the high heat energy generated by the laser generator to etch the semi-finished products. Forming; 3) Drilling and forming process of high-speed drilling machine: drilling and forming small holes one by one. The common disadvantages of the above processes are: long process, low efficiency, high cost, poor product consistency, a...
