Description
Technical Field
The utility model relates to a cold-heading mould, concretely relates to area side direction cold-heading mould that punches a hole.
Background
At present, for some shaft rod parts with lateral holes, if a cold heading die is adopted for cold heading forming, the structure of the cold heading die is more complex.
Disclosure of Invention
The utility model aims to provide a not enough to prior art, the utility model aims at providing a can be in the side direction hole of direct forming play axostylus axostyle part of cold-heading axostylus axostyle part, simple structure's area side direction cold-heading mould that punches a hole.
The utility model discloses a realize through following technical scheme:
take side direction cold-heading mould that punches a hole comprises mould and fixed lower mould on the punching press, its characterized in that: the punching upper die is provided with an upper die cavity, a punching pushing inclined plane is arranged beside the upper die cavity, and the punching pushing inclined plane is arranged to protrude out of the lower end face of the punching upper die; the fixed lower die is provided with a lower die cavity, the side wall of the lower die cavity is provided with a transverse hole, a lateral hole punch is movably arranged in the transverse hole, the tail part of the lateral hole punch is provided with a force bearing inclined plane, the force bearing inclined plane corresponds to the punching pushing inclined plane, the outer side of the tail part of the lateral hole punch is provided with an elastic stop pin, the elastic stop pin is arranged on the upper end surface of the fixed lower die, a spring pushes the lateral hole punch to outwards abut against the elastic stop pin, and the lateral hole punch is separated from the lower die cavity; when the cold heading is in work, after the upper punching die moves downwards, the punched hole pushes the inclined plane to contact and push the force bearing inclined plane to enable the lateral hole punch to enter the lower die cavity.
Above-mentioned technical scheme's area side direction cold-heading mould that punches a hole can be in the side direction hole of direct molding play axostylus axostyle part in cold-heading axostylus axostyle part, simple structure, and the process of cold-heading work is: when the blank reachd the below of mould on the punching press, the mould moves down on the punching press, with the lower extreme of blank push down the die cavity, the upper end of blank is located the die cavity, the mould continues downwards on the punching press, it can contact and promote the load inclined plane to punch a hole promotion inclined plane, make side direction hole drift enter into the die cavity down, so the blank carries out the cold-heading shaping in last die cavity down, side direction hole drift punches a hole to the blank, like this when axostylus axostyle part cold-heading shaping finishes, the side direction hole of axostylus axostyle part is also shaping simultaneously.
When axostylus axostyle part needs both sides to punch a hole, the technical scheme who adopts is: the punching pushing inclined planes are arranged on the left side and the right side of the lower die cavity, and the transverse holes are arranged on the left side wall and the right side wall of the lower die cavity.
Drawings
The utility model discloses there is following figure:
figure 1 is a schematic structural diagram of the present invention,
figure 2 is the fashioned shaft pole part with side direction hole of the utility model discloses the cold-heading.
Detailed Description
As shown in fig. 1, the cold heading die with lateral punching of the utility model comprises an upper punching die 4 and a lower fixed die 10, wherein the upper punching die 4 is provided with an upper die cavity a, the top of the upper die cavity a is provided with an upper guide hole 5, the upper guide hole 5 is used for the movable arrangement of a front through ejector rod of a cold heading machine, the left side and the right side of the upper die cavity a are provided with punching pushing inclined planes 6, and the punching pushing inclined planes 6 protrude out of the lower end surface of the upper punching die 4 for arrangement; the fixed lower die 10 is provided with a lower die cavity B, the bottom of the lower die cavity B is provided with a lower guide hole 9, the lower guide hole 9 is used for movably arranging a rear through ejector rod of a cold header, the left side wall and the right side wall of the lower die cavity B are provided with transverse holes 1, lateral hole punches 3 are movably arranged in the transverse holes 1, the tail parts of the lateral hole punches 3 are provided with force bearing inclined planes 7, the force bearing inclined planes 7 correspond to punching pushing inclined planes 6, the outer sides of the tail parts of the lateral hole punches 3 are provided with elastic stop pins 8, the elastic stop pins 8 are arranged on the upper end faces of the fixed lower die 10, springs 2 are arranged in outer side ports of the transverse holes 1, the springs 2 push the lateral hole punches 3 to outwards abut against the elastic stop pins 8, and at the moment, the lateral; during cold heading, after the upper punching die 4 moves downwards, the punching push inclined plane 6 contacts and pushes the force bearing inclined plane 7 to enable the lateral hole punch 3 to enter the lower die cavity B.
The utility model discloses a work like this: when the blank reachd the below of mould on the punching press, the mould moves down on the punching press, push the lower extreme of blank into the lower mould intracavity, the upper end of blank is located the die cavity, the mould continues downwards on the punching press, it can contact and promote the load inclined plane to punch a hole promotion inclined plane, make side direction hole drift enter into the lower mould intracavity, so the blank carries out the cold-heading shaping in last lower mould intracavity simultaneously, side direction hole drift punches a hole to the blank, like this when axostylus axostyle part cold-heading shaping is accomplished, the side direction hole of axostylus axostyle part is also shaping simultaneously, final fashioned axostylus axost.
