摘要

Device for the achievement of metal band joints, characterized in that the matrix that produces the incisions of unión of the bands goes, provided with an ejector that pushes the bands upwards in such a way that they remain free and not adhered to the punch as long as of the two band parts that are on top of each other towards the end of the upper band, they are curved in an arc that ensures a good position of the protruding part on the junction of the upper band, having provided that the males they are subject to the base platform and the females on the males in the mobile part of the installation carrying a set of female and male that with the same profile produces at the ends of the bands, a ripple. At the same time as the incisions, while of. On the other side there is a punch that consists of a crossbar connected to the body itself, for the extra curvature of the bands, which punch has a latch that serves as a guide and ensures the correct position of the bands, while arranging one of the levers that is provided, the device, attached to it the matrix in such a way that by actuating it allows to raise and lower said matrix on the bands resting on the punch and make the incisions at the end of its path that is regulated by half of a stop, i also provide in the same body a shear-type blade that together with the end profile of the matrix, makes the upper band cut while the device is provided with an axis that at one end it consists of a bite and in the other, joined to the same axis, two levers, one of which has an eccentric movement, lowers and raises the end of the shaft with a bite in such a way that it imprisons the bands, acting as a footswitch while in the other lever joined the same axis there is a cogwheel acting as an orica allows through the above mentioned sting drags the upper band and create the necessary tension for the joining operation.
