Embodiment
Below against accompanying drawing, by the description to embodiment, further detailed is made to embodiment of the present utility model
Thin explanation, it is therefore an objective to help those skilled in the art have to design of the present utility model, technical scheme it is more complete, accurate and
Deep understanding, and contribute to it to implement.
As shown in Figures 1 to 4, the utility model provide a kind of Wedge mechanism, including sliding seat, wedge punch-pin sliding block,
Oblique wedge concave die sliding block and driver, wedge punch-pin sliding block and oblique wedge concave die sliding block is movably are arranged on sliding seat, wedge
Cavity plate sliding block is provided with the first recessed guide plate, and driver, which is provided with, to be engaged first play the guiding role with the first recessed guide plate and convex lead
Plate, the first recessed guide plate has the first chute for allowing the first convex guide plate to be embedded in.The upper mould slotting tool that is arranged on mould and lower section it is oblique
Wedge punch-pin sliding block is engaged, and the driver being arranged on mould is engaged with the oblique wedge concave die sliding block of lower section, wedge punch-pin sliding block
Adjacent with oblique wedge concave die slide position, set insert is engaged for workpiece on wedge punch-pin sliding block and oblique wedge concave die sliding block
Carry out punch forming.When upper mould is descending, upper mould slotting tool and the contact of incline plane on wedge punch-pin sliding block promote wedge punch-pin sliding block
Towards being moved linearly at oblique wedge concave die sliding block position on sliding seat；Equally, on driver and oblique wedge concave die sliding block
Contact of incline plane, promote oblique wedge concave die sliding block on sliding seat towards being moved linearly at wedge punch-pin sliding block position.
As shown in figure 3, the first chute set on the first recessed guide plate is V-shaped groove, the first convex guide plate is V-structure, first
It is slidably matched, play the guiding role with the first recessed guide plate in convex guide plate insertion V-shaped groove, there are the first convex guide plate two symmetrically tiltedly to be put down
Fitted with two internal faces in V-shaped groove in face.As set by Fig. 4, the first recessed guide plate is to be obliquely installed on oblique wedge concave die sliding block, the
One convex guide plate is in driver to be obliquely installed, and the length direction of the first convex guide plate and the first recessed guide plate is parallel, it is ensured that driver
It is descending that oblique wedge concave die sliding block can be promoted to move.
As shown in Fig. 2 wedge punch-pin sliding block is provided with the second recessed guide plate, sliding seat is provided with and is engaged with the second recessed guide plate
