Jig for setting the resistance Stops in a Rotary Bending Machine
|
John H. Lohman |
San Antonio, Bexar County, TX |
Claims:
1. A jig for aid in positioning outer resistance stops in a rotary bender having a pair of bending pins set for simultaneously double bending an offset in a truss re-bar, said jig comprising a nonrectangular frame including parallel side and end bars, said side bars being slidable on said end bars for accommodating bender settings for re-bars with variable offsets, seating elements mounted intermediately on said side bars and shaped to nest against bender pins in their final bending positions so as to cause the inner edges of said side bars to traverse lines including optimum resistance stop positions, and index markings on said edges for complementary positioning of diagonally opposite resistance stops.
2. A jig for establishing the positioning of a fixed resistance stop in a bending machine of the type having a pair of bending elements set up to cooperate with the stop in forming stock of predetermined angularity, at least one of said bending members being movable, said jig comprising a frame having side and end members and seating members on said side members disposed, with relation to a first of said side members, for seating said bending members with said first side member marking a line along which said stop is to be placed.
3. A jig as described in claim 2 in which said frame is in the form of a nonrectangular parallelogram and the side members thereof are slidable on the connecting end members for adjusting the jig to form stock bends of varying dimensions.
4. A jig as described in claim 2 in which said seating members are adjustably mounted on said side members for accommodating stock of varying thicknesses.
5. A jig as described in claim 2 in which both of said side members are disposed with respect to said seating members, when said bending members are seated therein, to mark lines for placement of a pair of fixed resistance stops in a rotary bending machine.
Abstract:
Accordingly, the main object of the present invention is to provide an adjustable jig which greatly facilitates the positioning of the resistance stops in a rotary bending machine set up for forming reinforcing bars of the type described. In accordance with this invention, the jig is constructed of parallel ruling bars slidably mounted on parallel, nonrectangularly disposed rods so that the bars may be variably spaced in order to accommodate different re-bar offset dimensions. Complementary slider members are mounted intermediately on each parallel bar for seating against the bender pins, when in their "end of bend" positions. The sliders are adjustable to accommodate reinforcing bars of varying thicknesses. In the seated position of the jig, as explained, the inner edges of the parallel bars form rules with linear markings which guide the placement of markings on the stationary table to mark the positioning of the working ends of the mentioned resistance stops. |
