Impact forming method for hydraulic valve end shield

Abstract

One kind of hydraulic pressure valve end shielding ramming take shape method, is realized according to the following steps,the initially take shape; Separately install the raised membrane and the concave membrane on the punch press work table and on the drift, starts the punch press, ram the sheet to become the sphere semifinished material; Reduces takes shape;installs the spread membrane which is the size shape with inner hole of the work, separately in the punch press work table and the drift, starts the punch press, presses evenly sphere crown of the sphere round hat semifinished materials, and reduces the lower part of the sphere, ramming full circle tubular, also hat brim presses evenly the sphere round hat semifinished materials circular, forms outside the belt along circle tubular semifinished materials; Stereotypia;install the work piece the hole size, the shape same raised membrane and with the work piece outer diameter size, the shape same concave membrane separately in the punch press work table and the drift, will start the punch press side,ramming the circle tubular semifinished material to the shape, the size tallies the request work piece semifinished materials, cutsthe work piece semifinished materials, namely will get the work piece which is conformed to the request.

Description

technical field [0001] The invention belongs to a metal stamping processing method, in particular to a hydraulic valve end cover stamping forming method. Background technique [0002] The end shield is a part of the multi-way reversing valve. At present, the part is usually processed by casting. However, the end shield processed by the casting method is relatively rough in appearance and is also very heavy. Because its side wall is thicker, more metal materials will be consumed. Moreover, the cast end shield has to be cut to become a finished end shield, so the cost of the workpiece is relatively high. [0003] The metal stamping forming process is one of the basic methods of plastic processing. It is mainly used to process sheet metal parts, so it is sometimes called sheet metal stamping. Stamping production relies on molds and stamping equipment to complete the processing process, so it has high productivity, easy operation, easy mechanization and automation, stable qual...
