Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, provides a kind of punching blanking mould, and it is fast changeable drift not only, and structure is simple, convenient operation, processing flexibly, reduces costs, but also can punching press plurality of specifications goods, efficiency is high, and cost is low.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of punching blanking mould, and it comprises:
Die holder, described die holder has punch support part and female mold support part, forms sheet material put area between punch support part and female mold support part;
Embed die, described embedding die is arranged on the female mold support part of die holder;
Punch-head assembly, described punch-head assembly has drift, and described drift is through the punch support part of die holder, and drift can move relative to punch support part, and drift matches for use in sheet material blanking with embedding die;
Returning spring, described returning spring is arranged between punch-head assembly and punch support part.
Further in order to can when punching press, the good sheet material of pressure holding, avoid it to rock, improve punching precision, punching blanking mould also comprises sheet material pressure holding mechanism, this sheet material pressure holding mechanism comprises discharging sleeve and discharging cushion, discharging sleeve is sliding to be fitted in the punch support part of die holder, discharging cushion is arranged between discharging sleeve and punch support part, one end and the punch-head assembly of described returning spring abut against, the other end and this discharging sleeve abut against, and described discharging sleeve moves under the comprehensive function of returning spring and discharging cushion in punch support part.
Further in order to conveniently blanking can be collected, the female mold support part of die holder is provided with material-dropping hole, and this material-dropping hole is connected with the drift mating cavity embedding groove.
Further under the prerequisite ensureing certain support strength, save material, alleviate die holder weight, the coupling part between die holder upper punch support section and female mold support part is I-shaped structure.
Further, discharging cushion is made up of elastomeric material.
Further provide a kind of concrete structure of punch-head assembly, punch-head assembly also has packing ring, and the afterbody of described drift is inlaid in packing ring.
After have employed technique scheme, during punching press, pressure acts on the upper surface of punch-head assembly, make the downward punching press of drift, punch-head assembly makes returning spring compress, and power is passed to discharging sleeve, power is passed to discharging cushion by discharging sleeve, discharging cushion is compressed, discharging sleeve moves down, the sheet material be stamped is pressed in and embeds between die and discharging sleeve, drift enters embedding die, complete punching and blanking, remove the pressure on drift, discharging cushion and the release of returning spring elastic force, make punch-head assembly and discharging sleeve homing, so just can quick-replaceable drift, structure is simple, convenient operation, processing flexibly, reduce costs, but also punching press plurality of specifications goods can be carried out by changing the drift embedding die and coupling, efficiency is high, cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of punching blanking mould of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation.
As shown in Figure 1, 2, a kind of punching blanking mould, it comprises:
Die holder 7, die holder 7 has punch support part 71 and female mold support part 72, forms sheet material put area between punch support part 71 and female mold support part 72;
