Abstract
The utility model relates to a quincuncial punch bar, which is an integrally formed structure and comprises a cylindrical handle (1). A circular-truncated-cone-shaped transitional portion (2) is arranged at the front end of the handle (1), a punch (3) with a quincuncial section is connected to the front end of the transitional portion (2), six indented arcs (4) with identical diameters are uniformly arranged to form the quincuncial section, arc tops of the six indented arcs are tangent to a punch inner circle (5), transitional arcs (6) are disposed at connection positions of the arc tops of the six indented arcs and the punch inner circle (5), tops of the transitional arcs are tangent to a punch outer circle (7), and three chip grooves (8) which are uniformly arranged are disposed on the transitional portion. When the quincuncial punch bar is used for punching processing, a quincuncial hole can be formed at one step, work efficiency is greatly improved, appearance deviation of products which are produced by the same punch bar is low, and the precision of the products is higher. The quincuncial punch bar is provided with the circular-truncated-cone-shaped transitional portion, the strength of the punch bar is strengthened, and the service life of the quincuncial punch bar is prolonged.
Description
Technical field
The utility model relates to a kind of towards tool, and particularly a kind of plum blossom dashes rod.
Background technology
In the prior art,, generally on workpiece, process circular hole in the plum blossom earlier, re-use the engraving machine engraving in the man-hour that adds of carrying out plum blossom hole; So, processing cost is high, and efficient is very low, and; Deviation appears in six fillets easily that carve out, to such an extent as to structure is asymmetric, influences result of use.
The utility model content
In order to overcome the prior art defective, the purpose of the utility model is, provides a kind of and can dash rod through the one-time formed plum blossom of punching press.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is following:
A kind of plum blossom dashes rod, and its structure that is formed in one comprises a columniform shank; Shank forward end is provided with a round table-like transition portion, and the transition portion front end is connected with the drift that a cross section is the plum blossom shape, and said plum blossom shape is that the interior concave arc of evenly distributed six sections equal diameters is formed by connecting; Concave arc arc top is tangent with the interior circle of drift in said six sections; Its junction is provided with transition arc, and said transition arc arc top is tangent with the drift cylindrical, and said transition portion is provided with three evenly distributed chip areas.
Further,
Said indent arc radius is 1.12mm;
Said transition arc radius is 0.51mm;
Circular diameter is 4.05mm in the said drift;
Said drift outside diameter is 5.6mm;
Said shank diameter is 8mm.
The beneficial effect of the utility model is: use the plum blossom of the utility model to carry out punch process towards rod, but its plum blossom shape hole one-shot forming has improved operating efficiency greatly, and used same product design deviation of producing towards rod little, precision is higher; The utility model plum blossom has the round platform transition portion towards rod, has strengthened towards excellent intensity, has improved service life.
Description of drawings
Fig. 1 dashes the structural representation of rod for the utility model plum blossom;
Fig. 2 dashes the punch structure sketch map of rod for the utility model plum blossom.
The specific embodiment
Like Fig. 1, shown in Figure 2:
The plum blossom of present embodiment dashes rod, and the structure that is formed in one comprises a columniform shank 1; Its front end is provided with a round table-like transition portion 2; To increase the bonding strength of shank and drift, transition portion 2 front ends are connected with the drift 3 that a cross section is the plum blossom shape, and said plum blossom shape is that the interior concave arc 4 of evenly distributed six sections equal diameters is formed by connecting; Concave arc arc top is tangent with drift interior round 5 in said six sections; Its junction is provided with transition arc 6, and said transition arc arc top is tangent with drift cylindrical 7, and said transition portion is provided with three evenly distributed chip areas 8; The metal fillings that extruding produces in the punching course is discharged by chip area 8, can not damage to guarantee workpiece and drift.The radius of interior concave arc 4 is 1.12mm, and the radius of transition arc 6 is 0.51mm, and the diameter of circle 5 is 4.05mm in the drift, and the diameter of drift cylindrical 7 is 5.6mm, and the diameter of shank 1 is 8mm.
Use the plum blossom of the utility model to carry out punch process towards rod, but its plum blossom shape hole one-shot forming has improved operating efficiency greatly, and used same product design deviation of producing towards rod little, precision is higher; The utility model plum blossom has the round platform transition portion towards rod, has strengthened towards excellent intensity, has improved service life.
