Abstract

The invention relates to a stamping die with replaceable inserts. The stamping die comprises a female die plate, the male die inserts and the female die inserts. The stamping die is characterized in that under the condition that the diameters of outer circles of stamped steel products are identical, according to different shaft hole diameters and key groove shapes of the stamped steel products, the four female die inserts are mounted on the female die plate in the four positive directions according to different distributions of the shaft hole diameters; according to the key groove positions of the stamped steel products needing to be manufactured, the male die inserts corresponding to the female die inserts are mounted on the female die inserts. The stamping die has the advantages and the beneficial effects that the stamping die is suitable for machining various products with the identical outer circles and identical buckle slab grooves and with different shaft hole diameters and different key grooves; when one of the products is produced, the corresponding female die inserts can be all mounted in the female die plate, and different female die inserts can be mounted for production according to the different sizes of the key grooves of the products; the number of made dies is reduced, the universality of the die is improved, and manufacturing cost is lowered.

Description

technical field [0001] The invention belongs to the field of punching manufacturing, in particular to a punching die used for punching out replaceable inserts of sheet products. Background technique [0002] In the prior art, many stamped sheet products have complex shapes, and some products belong to the same series. Although the outer circle is the same, the outer circle buckle groove, shaft hole diameter, and shaft hole keyway vary according to the number of motor stages. Variety. In order to meet the production needs of these products, to produce high-quality qualified products and reduce costs, it is necessary to design a mold with strong versatility to avoid unnecessary losses to the enterprise. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides a stamping die structure with replaceable inserts, which has reasonable structural design, strong versatility, and can effectively reduce the p...
