Abstract
The invention discloses a metal part and insulating part stamping and bonding method which comprises the following steps: stamping two sides of a piece of yellow adhesive paper and a piece of bottom release paper with a first cutting die; peeling the middle part of the bottom release paper, and bonding an insulating piece to the middle part of the yellow adhesive paper; stamping the insulating piece with a second cutting die, so that a first blow hole and at least one first pre-folding line are formed in the insulating piece; stamping a metal part through a first steel die and a second steel die; bonding the insulating piece to the metal part through the bonded parts on two sides of the yellow adhesive paper; cutting the insulating piece and the metal part through a third steel die so as to form multiple semi-finished products; stamping the semi-finished products through a fourth steel die, and bending the semi-finished products along a first pre-folding line and a second pre-folding line, thus obtaining a finished product.
Description
technical field [0001] The invention relates to a stamping and bonding method of a metal part and an insulating part, in particular to a metal part and an insulating part which are stamped, aligned and bonded by a machine, and then cut and bent by a machine. Stamping and bonding methods for insulating parts. Background technique [0002] Press, the known stamping and bonding method of metal parts and insulating parts is to stamp the metal parts and insulating parts separately, then paste the insulating parts and metal parts, and finally cut and bend the metal parts and insulating parts . But above-mentioned known method has following shortcoming: [0003] 1. When pasting insulating parts and metal parts manually, it will be time-consuming and the quality will be unstable due to inaccurate alignment; and [0004] 2. The insulation part will warp (rise) relative to the metal part, which is really a fly in the ointment. Contents of the invention [0005] The object of the...
