Description
Technical field
The utility model relates to a kind of blanking mould, especially a kind of cold punching blanking die that is applied on the stamping machine.
Background technology
In traditional mechanical processing industry, extensively adopt sawing, this cutting mode has following shortcoming: waste of material, sawing is by circular saw cutting carrying out blank, therefore will inevitably be cut by some blank, and the smear metal of splashing had both threatened people's eyes, also environment on every side and equipment was produced harm; Circular saw self rigidity is low, can not cut a plurality of blanks, inefficiency simultaneously; Circular saw occurs the card saw easily in cutting process even saw blade damages, and therefore the blank that downcuts contains burr, and cross section quality is poor, causes the waste of unnecessary material and instrument, increases production cost.
At present, some processing industry begins to adopt the stamping machine cut mode to replace original sawing, though having solved original blank mode consumes greatly, inefficient shortcoming, but because of project organization too complicated, the cost of cost improves in the mould design, therefore being not suitable for medium and small processing industry promotes the use of, and for example the patent No. is to disclose a kind of bar shearing die in the patent application of 200410012515.X, it mainly is by last, following two clamping devices that are crisscross arranged are realized the clamping of bar, shear by cutting edge again, but when designing mould, need be to last, the clamping force of following two clamping devices is calculated, if the clamping dynamics of two clamping devices is inconsistent, bar will occur tilting when clamping, the bar cross section quality variation of shearing.
Summary of the invention
Problem to be solved in the utility model is exactly the shortcoming of prior art, provides a kind of simple in structure, the cold punching blanking die that working (machining) efficiency is high, and the cutter loss is little, and production cost is low, and the quality of blank is good, raw-material utilization rate height.
To achieve these goals, the utility model has adopted following technical scheme: a kind of cold punching blanking die, comprise top mold frame, die shoe, it is characterized in that: die shoe connects the die that is used to place blank, die inside has the charging conduit of hollow structure, top mold frame connects punch assemblies, and this punch assemblies compresses and cutting blank with die upper surface and charging conduit mating reaction respectively.
Further, described punch assemblies comprise the blanking cutting die that is complementary with the charging conduit shape and be nested with at the blanking cutting die outside and with the clamping device of top mold frame interlock.
Further, described clamping device comprises with the holding pad of die upper surface mating reaction and acts on the elastomer block of holding pad that under free state, the bottom end face of holding pad exceeds the following knife face of blanking cutting die.After punching press began, holding pad was at first made in blank and it is compressed, and along with the continuation of top mold frame is descending, elastomer block is compressed, and increase and maintenance are to the pressure of blank, and binder blank extreme difference is synchronous; Apparatus structure, principle are simple, clamp effective.
Further, described die upper surface is provided with the upper groove that several are used to place blank, and the following knife face of the bottom end face of holding pad and blanking cutting die is provided with respectively with the corresponding low groove of described upper groove and is used to compress and cutting blank.
As preferably, be provided with the combination of two pairs of upper grooves and low groove between the bottom end face of described die upper surface, holding pad and the following knife face of blanking cutting die.
Further, also comprise the stock stop that is installed in the die shoe rear end, comprise striker plate and the discharging device that is used with this backgauge, two ends of striker plate are connected with die shoe rear end face elasticity by extension spring.
Further, described discharging device comprises two limiting plates that are installed in parallel in the die shoe rear end face, have the stopper slot that is used to wear striker plate on the limiting plate, the both sides of top mold frame respectively are provided with L shaped connecting rod, and the other end of L shaped connecting rod extends to the installation place of striker plate and acts on the elastic chuck of striker plate in the medial surface setting of this end.
Further, also be provided with the material returned bar of two bending-likes between described two limiting plates, material returned bar tail end and striker plate mating reaction, the active switching in the middle part of material returned bar are on limiting plate, and the front end of material returned bar connects by rotating shaft and is slidingly arranged in the kidney slot of limiting plate.
As improved, be provided with two pairs of guide pillar mechanisms that be arranged in parallel between described top mold frame and die shoe.Location and guiding by guide pillar mechanism have reduced the kinematic error between die and punch assemblies, the unanimity that has guaranteed charge length with accurately, the service life that also can improve mould simultaneously.
Advantage of the present utility model: adopt the combination of die and punch assemblies, the synchronous working method of binder blank extreme difference, not only operating efficiency is greatly high, and the clamping of blank is effective, thereby the quality of blank section improves; Adopt the binary channels parallel feed, can realize the cutting length independent assortment of same specification blank; The induction backgauge triggers, and has further improved operating efficiency; Mold integral is simple in structure, easy to operate, and loss is little, and cost is low, is to be fit to the blanking mould that numerous processing industries are used.
