Abstract

The utility model discloses a high guidance precision punching die of a cantilever base body. The high guidance precision punching die of the cantilever base body comprises a punch fixed plate, a female die, a punch which is arranged at the lower end of the punch fixed plate, an unloading plate which is connected with the lower end of the punch fixed plate through a bolt in suspension mode, and a die shank which is fixedly arranged at the upper end of the punch fixed plate. The lower end of the punch stretches out of the unloading plate, and a material-knocking rod is arranged at the upper end of the unloading plate in overhead mode and penetrates through the die shank and the punch. A female die cavity is arranged on the upper end face of the female die, and the female die cavity is of a cone shape. After the female die cavity and the punch are carried out hot forging in matched mode, the cantilever base body blanking is carried out, so that processing efficiency is further improved, and the high guidance precision punching die of the cantilever base body can be carried out punch forming in mass, is high in guidance precision and improves precision of form and position of a cantilever base body.

Description

A kind of perforating die of high guiding accuracy cantilever base body

Technical field

The utility model relates to a kind of perforating die of high guiding accuracy cantilever base body.

Background technology

Blanking die is the mould that material production is separated along the outline line that seals or open wide.Such as blanking die, perforating die, knife edge die, notch die, edger, parting die etc.After the present cantilever base body process forge hot, the shape basic forming of cantilever base body, but dimensional accuracy does not still reach the dimensional requirement of design, need to carry out next step Blanking Shaping and process.

The utility model content

The purpose of this utility model provides a kind of perforating die of high guiding accuracy cantilever base body, the cantilever base body to after the forge hot that adopts cavity impression to cooperate with drift carries out stamping-out, guiding accuracy is high, working (machining) efficiency further improves, can carry out in enormous quantities punch forming, improve the accuracy of form and position of cantilever base body.

The technical solution of the utility model is as follows:

A kind of perforating die of high guiding accuracy cantilever base body, include punch fixing plate, former, the lower end of punch fixing plate is installed with drift, the lower end of punch fixing plate is connected with stripper by hung bolt, the upper end of punch fixing plate is installed with die shank, stretch out outside the stripper lower end of drift, die shank, pass the knockout rod overhead in the drift in the upper end of stripper, have cavity impression on the upper surface of former, it is conical that cavity impression is, have the pilot hole corresponding with drift on the stripper, be combined with fairlead in the pilot hole, the upper end of fairlead is horn-like.

Have stepped hole on the described stripper, be screwed with described bolt in the punch fixing plate, the lower end of bolt is matched with in the stepped hole.

The cantilever base body to after the forge hot that the utility model adopts cavity impression to cooperate with drift carries out stamping-out, and working (machining) efficiency further improves, and can carry out in enormous quantities punch forming, and guiding accuracy is high, has improved the accuracy of form and position of cantilever base body.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Referring to accompanying drawing, a kind of perforating die of high guiding accuracy cantilever base body, include punch fixing plate 1, former 2, the lower end of punch fixing plate 1 is installed with drift 3, the lower end of punch fixing plate 1 hangs by bolt 4 and is connected with stripper 5, the upper end of punch fixing plate 1 is installed with die shank 6, stretch out outside the stripper 5 lower end of drift 3, die shank 6, pass the upper end that dnockout 9 mastheads place stripper 5 in the drift 3, have cavity impression 7 on the upper surface of former 3, it is conical that cavity impression 7 is, and has stepped hole 8 on the stripper, is screwed with bolt 4 in the punch fixing plate 1, the lower end of bolt 4 is matched with in the stepped hole, have the pilot hole 9 corresponding with drift 3 on the stripper 5, be combined with fairlead 10 in the pilot hole 9, the upper end of fairlead 10 is horn-like.
