Centre bore, connects antermarginal part at installing plate 201 and is machined with installing hole；The processing of existing installing hole uses first punching,
Squeeze hole again, then bore the operation of counterbore, therefore there is the control of accurate to dimension difficulty, error greatly, operate loaded down with trivial details, production efficiency
Low problem.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of wheel spoke punch die, and this mould can solve
Existing wheel spoke hole machined dimensional accuracy error is big, the problem that production efficiency is low.
In order to solve the problems referred to above, this utility model be the technical scheme is that this wheel spoke punch die, including
The punch being located on upper bolster and the die being located on Workpiece clamping seat, described upper bolster abuts against with the bottom of upper installing rack,
Described Workpiece clamping seat is abutted against by the top of workbench with lower installing rack；The middle part of described Workpiece clamping seat is equipped with a workpiece
Locating piece；The upper installing rack on described upper bolster side has extended downwardly from upper mold limited post, and described lower installing rack is provided with upwards
The lower mold limited post corresponding to described upper mold limited post stretched out；Described punch includes crowded Kong Zhu and punching post, the institute of cylinder
Stating the capital end connection of crowded hole and have molding cone, connecting between described crowded Kong Zhu and punching post has expansion cone, at the bottom of described punching post
End is provided with top, and described molding cone and expansion cone are up big and down small cone, the angle of bevel of described molding cone
For a, the angle at described expansion cone oblique angle is b；The die cavity of described die is post holes, and its opening part inwall is arcwall face, described
Arcwall face is limited by the circular arc that radius of curvature is 0.2 millimeter～0.5 millimeter, the gap between described punch hypomere and concave die cavity
For H, H=D2-D1, D1 are punching column diameter, and D2 is the diameter squeezing Kong Zhu.
In above-mentioned technical scheme, more specifically technical scheme is it may also is that described punch is installed on by its installing handle
On upper bolster, described angle a is 30 degree, and described angle b is 9.5 degree, a diameter of 13.6 millimeters of described punching post；Described crowded hole
A diameter of 14.35 millimeters of post；A diameter of 14.5 millimeters of described concave die cavity.
Owing to have employed technique scheme, this utility model compared with prior art has the advantages that
1, owing to having extended downwardly from upper mold limited post in upper installing rack one end, lower installing rack is provided with and protrudes upward
Lower mold limited post corresponding to upper mold limited post；Can the degree of depth in impact extrusion hole be carried out spacing, it is ensured that spoke installing hole epimere is bored
The size of face.
2, Kong Zhu top, crowded and the punching post arranged by level from the bottom up due to die section is constituted, it is ensured that hole is squeezed in punching
Carry out simultaneously；
3, owing to the diameter of punching post is less than the diameter squeezing Kong Zhu；Section bar is made to possess the space of flowing；
4, being arcwall face due to the opening part inwall of die, arcwall face is 0.2 millimeter～the circle of 0.5 millimeter by radius of curvature
Arc limits；Die can be fitted tightly with workpiece.
5, all it is movably mounted on respective installing rack due to punch mounting seat and Workpiece clamping seat；Easy disassembly, more
Change.
