As the preferred scheme of one, described interior tool rest both sides are respectively equipped with some back-moving springs.
As the preferred scheme of one, described upper bolster is provided with the mounting groove for arranging slotting tool, is also provided with the adjustment key for adjusting slotting tool position in mounting groove.
As the preferred scheme of one, described die shoe is provided with dynamic clamp assembly and the given clamp that cut piece is treated in clamping, and dynamic clamp assembly comprises the dynamic chuck be slidably arranged on die shoe and the cylinder driving dynamic chuck.
As the preferred scheme of one, outside described slotting tool, be provided with wearing plate.
The invention has the beneficial effects as follows: owing to being provided with the drive block driving inner cutter, drive block both sides are respectively equipped with left protruding block and right protruding block, left protruding block and right protruding block are positioned on differing heights, inner cutter can be driven when drive block is moved downward to move left and right, coordinate two the outer cuttves in left and right, realize the cut-out to part both sides respectively successively, the punching press time is short, punching press single-piece 10S can complete, and clamping is easy, and after cutting off, workpiece can not produce deformation.
Because interior tool rest both sides are respectively equipped with some back-moving springs, after drive block moves, interior tool rest can guarantee that under the effect of both sides back-moving spring position is just returned, and is convenient to the carrying out of next operation.
Because upper bolster is provided with the mounting groove for arranging slotting tool, being also provided with the adjustment key for adjusting slotting tool position in mounting groove, when being convenient to assembling and setting, slotting tool position being adjusted, make assembling easily.
Because die shoe is provided with dynamic clamp assembly and given clamp that cut piece is treated in clamping, more stable to the clamping of workpiece, during cut-out, workpiece not easily rocks.
