Description
Technical field
The utility model relates to a kind of split type abnormal-shaped punch structures of band bullet ejector pin.
Background technique
The shape of automobile panel is more complicated, and deburring profile majority is solid irregular, often has some abnormal shapes
Hole and some sizes exceed standard component size range hole.For the maintenance and installation side of mold in the mold design in this hole
Just, it needs using nonstandard punch structure, conventional design is using monoblock type punch structure (as shown in Figure 1).This structure
Manufacture and maintenance cost are relatively high, and formed punch use, which is broken, to be needed entire formed punch replacement and waste material cannot be ejected automatically.
Utility model content
The purpose of this utility model be in view of the above problems, provide a kind of split type abnormal-shaped punch structure of band bullet ejector pin,
Traditional monoblock type punch structure is changed to the split type abnormal-shaped punch structure for playing ejector pin, formed punch and the fixation of working portion
Fixing seat separates, and using different materials, optimizes part manufacturing process, thus reduce abnormal-shaped punch manufacture and later period maintenance at
This.And bullet ejector pin is devised on split type abnormal-shaped punch, ejector pin is played after the completion of punching to be gone waste material ejection to avoid automatically
The complete card waste problems of punching.
In order to achieve the above object, the technical solution adopted in the utility model is: it includes that abnormal-shaped punch, abnormal-shaped punch are fixed
The bottom of seat, backing plate, ejector pin, spring and screw plug, abnormal-shaped punch is provided with hanging platform；The upper end of abnormal-shaped punch passes through abnormity punching
After through-hole in head fixing seat, hanging platform is matched in the groove of via bottoms；Abnormal-shaped punch successively includes the first circle from top to bottom
Hole, the second circular hole and threaded hole, the first circular hole, the second circular hole and threaded hole are concentric setting, and the upper end of ejector pin is round from second
The first circular hole is upward through in hole, screw plug is fixed in threaded hole, and spring is arranged between ejector pin bottom and screw plug；
It is fixed between backing plate and abnormal-shaped punch fixing seat by screw.
Further, win was used to cooperate between abnormal-shaped punch and through-hole.
Further, abnormal-shaped punch is formed with abnormal-shaped punch fixing seat cutting edge matching part using linear cutter.
The utility model has the beneficial effects that the utility model provides a kind of split type abnormal-shaped punch knot of band bullet ejector pin
Structure, traditional monoblock type punch structure are changed to the split type abnormal-shaped punch structure for playing ejector pin, the formed punch of working portion and solid
Fixed fixing seat separates, and using different materials, optimizes part manufacturing process, to reduce abnormal-shaped punch manufacture and later period maintenance
Cost.And bullet ejector pin is devised on split type abnormal-shaped punch, ejector pin is played after the completion of punching to be gone waste material ejection to keep away automatically
Exempt from the complete card waste problems of punching.
