The utility model content
The technical problems to be solved in the utility model provides a kind of blanking and stretching composite structure that is contained on the forcing press, realizes blanking and two actions that stretch at a station, has both improved working (machining) efficiency, cuts down finished cost again.
For achieving the above object, the technical solution of the utility model is: a kind of blanking and stretching composite structure that is contained on the forcing press, comprise: by the vertical shaft of the synchronous driven rotary of principal axis of pressing machine, fix a cylindrical cam on the vertical shaft, cylindrical cam is provided with a circle gathering sill at outer peripheral face; The centre of a fork is articulated on the fulcrum that is fixed in forcing press, and an end of fork is provided with projection and matches with the gathering sill of cylindrical cam, and cylindrical cam rotates an astragal movable pendulum bar and swings up and down once; One die is fixed on the workbench of forcing press, one punch is fixed on the slide block of forcing press, and the intermediate sleeve of punch has a stretching bar, and the lower end of stretching bar is stretching convex die, the upper end of stretching bar and the other end of fork are hinged, and drive the stretching bar when fork swings up and down and move up and down.
Further improve, a contiguous block is fixed in described stretching bar upper end, contiguous block is provided with a connecting groove, groove between two adjacent engaging tooths of described connecting groove shape and cylindrical gear is identical, fork is provided with the detent projection identical with cylindrical gear engaging tooth shape with the link of stretching bar, the detent projection of fork link matches with the connecting groove of contiguous block, better drives the stretching bar by swinging up and down of fork and moves up and down.
Preferred described vertical shaft is connected by the main shaft of a pair of angular wheel and forcing press, realizes that better the spindle synchronous of forcing press drives vertical shaft rotary.
The utility model is owing to the intermediate sleeve at punch has a stretching bar, moving up and down of stretching bar is to drive by fork, and moving up and down of punch is that slide block by forcing press drives, so just can make stretching bar and punch dislocation motion, namely allow stretching bar and punch Asynchrony, allow first punch is descending to carry out die-cut blanking to sheet material, then the slide block down that utilizes again forcing press has short stay to push down workpiece during to the dead point, allow again the lower end of the further descending utilization stretching bar of stretching bar that workpiece is stretched, be implemented in and finish blanking on the station and two actions that stretch, both improved working (machining) efficiency, cut down finished cost again.
Vertical shaft of the present utility model is the main shaft drive synchronous rotary by forcing press, fix again a cylindrical cam on the vertical shaft, cylindrical cam is provided with a circle gathering sill at outer peripheral face, curved surface by appropriate design cylindrical cam gathering sill, the rhythm by cooperate better restrained stretching bar to move up and down with fork again, therefore the rotation that to utilize a power source be main shaft just realizes blanking and two actions that stretch, and is simple in structure and energy-conservation, further cuts down finished cost.
Description of drawings
