C shape punching machine, roll forming machine

Detailed Product Description

C shape punching machine

 A punching machine for use in punching holes in the sides of a shape comprising:

a frame;

a press forming punch closing control means having a fixed portion integral with the frame of the machine and having a mobile platform;

two generally C-shaped assemblies including at least two arms carried by the frame juxtaposed and disposed symmetrically in relation to each other; each assembly comprising a first part which constitutes one arm of a C-shape assembly bearing apunching tool and which is mounted axially and slidably on said mobile platform of said press and a second part which constitutes the other arm of said C-shape assembly and which is mounted axially and slidably on the frame parallel to the sliding axisof the said first part;

connecting means provided to interconnect each of the said first parts to the corresponding second part;

means provided for controlling the forward movement of said punch tool;

means provided for regulating and maintaining said assemblies in a working position, with a predetermined spacing of said punch tools, said C-shape assemblies being guided within said machine in such a way that said C-shape assemblies can bedisplaced and moved further from each other; and

means for controlling and positioning said C-shape assemblies, firstly, in a working position in which the position of one of said punch tools is maintained at a predetermined distance from a guide plane coinciding with a guiding surface on theshape to be punched and in which the spacing of the tools is maintained at a predetermined value, and secondly in a position to rotate the shape to be punched such that each of said C-shape assemblies is displaced in relation to its working position inthe sense of an increase in the distance separating said assemblies.
