Tooling for fixing hooks connecting the ends of belt conveyors

Tooling intended for fixing hooks connecting the ends of a belt conveyor of the type including an upper plate (5′) and a lower plate (5′″) connected by lugs (5″), liable to be positioned on the ends of a conveyor belt (BT) in two respective series, with the lugs (5″) of both respectively opposite series being able to be connected after having being imbricated, by a linking and swivel rod, like a hinge, said tooling including a movable upper part (2) and a fixed lower part (3) positioned and centered with respect to each other by positioning and centering means, with the upper part (2) being able to vertically slide towards or away from the lower part (3), the lower part (3) including an anvil (3′) and wedging means intended for the lower plate (5′″) of a hook (5) positioned between the upper part (2) and the lower part (3) of the tooling, the upper part (2) of the tooling including a vertical channel (2′) liable to receive a main punch (1) substantially centered above the anvil (3′) and being able to be hammered, using a manual hammer or a device of the pneumatic, electromechanical or hydraulic hammer type mounted in the upper part (2) of the tooling, to drive in staples (7) preferably engaged with capping into holes provided in the upper plate (5′) of a connection hook (5) positioned astride on the rim of one end of a conveyor belt (BT) positioned between the upper part (2) of the tooling and the lower part (3) of the tooling, then in the material of the end of the conveyor belt, with the prongs thereof being further folded either under the lower plate (5′″) of the hook (5) and meeting recesses having an appropriate shape provided in the anvil (3′) of the lower part (3) of the tooling or under a bridge or bridges provided in the lower plate (5″′) of the hook (5) with the upper part of the lower plate (5′″) of the hook playing the part of an anvil, with the lower face of the lower plate (5″′) of the hook resting on the anvil of the lower plate of the tooling which, in the later case, is smooth,

• the upper part (2) of the tooling including a second vertical channel (2″′) in which a complementary punch (4) is mounted so as to be able to slide in this channel (2″′) parallel to the main punch (1) while being juxtaposed next to such main punch (1),
• wherein the complementary punch (4) is positioned so that the lower end thereof is accurately located above the part of the upper plate (5′) of the hook (5) located between the lugs (5″)and the branch of the staple (7) which is the closest to the lugs (5″), the arrangement of both punches being such that the complementary punch (4) starts being hammered, whereas the main punch (1)continues being hammered, only when the main punch (1) has driven the staple and applied the part of the upper plate (5′) of the hook (5) located under the staple (7) against the upper face of the end of the conveyor belt (BT).
