Abstract
The invention discloses a processing technology for a blanking female die. The processing technology comprises the following steps: 1) preparing a material, and forging a blank with phi 210mm and M 40mm; 2) annealing the forged blank; 3) turning an excircle and an end face, wherein the excircle has the dimensions of phi 200mm and thickness of 40mm; 4) marking off, drilling a threaded hole M8 and a pin hole with phi 7.8mm; 5) quenching, tempering, and ensuring that the hardness HRC is 60-64; 6) grinding to ensure the boundary dimension; 7) demagnetizing by a fitter; 8) performing wire cutting on a shape and holes; 9) grinding each fitting surface to meet the requirement; and 10) warehousing after the blanking female die is checked to be qualified. The processing technology has the characteristics of high accuracy, simple structure and long service life.
Description
Technical field
The present invention relates to a kind of processing technology of mould, particularly relate to a kind of processing technology of blanking die.
Background technology
Defectives such as in the prior art, the processing technology of the recessed film of punching exists the processing dimension inaccuracy, service life is short, burr is many, pressure transient.
Summary of the invention
Purpose of the present invention is exactly for overcoming defective and the deficiency that above-mentioned prior art exists, and a kind of processing technology of blanking die is provided.
The technical scheme that adopts is:
The processing technology of blanking die is characterized in that comprising following processing step:
1 gets the raw materials ready, and blank is swaged into ￠ 210mm, M40mm;
2, the blank that is swaged into is annealed;
3, turning and end face, cylindrical is to size ￠ 200mm, thickness 40mm;
4, line, auger shell pit M8, pin hole. ￠ 7.8mm;
5, quenching, tempering guarantee HRC60-64;
6, mill processing guarantees appearance and size;
7, pincers worker demagnetization;
8, line cutting profile and hole;
9, grind each mating surface and reach requirement;
10, put in storage after the assay was approved;
Major advantage of the present invention is:
(1) adopt machining center to bore, mill, dimensionally stable, the position is accurate.
(2) adopt advanced forcing press pressure oil groove and oil film wedge face.Pressure stability, dual fail-safe, size adjustable.
(3) mould adopts insertedly, has the characteristics of precision height, simple in structure, long service life.
The specific embodiment
The processing technology of blanking die, its characteristics are to comprise following processing step:
1 gets the raw materials ready, and blank is swaged into ￠ 210mm, M40mm;
2, the blank that is swaged into is annealed;
3, turning and end face, cylindrical is to size ￠ 200mm, thickness 40mm;
4, line, auger shell pit M8, pin hole. ￠ 7.8mm;
5, quenching, tempering guarantee HRC60-64;
6, mill processing guarantees appearance and size;
7, pincers worker demagnetization;
8, line cutting profile and hole;
9, grind each mating surface and reach requirement;
10, put in storage after the assay was approved.
