Abstract
The utility model discloses a compound die rigid waste ejecting mechanism and relates to a die part. The compound die rigid waste ejecting mechanism comprises an upper die seat, a die shank and a punch die. The punch die is fixedly connected with the lower surface of the upper die seat, and a punching type hole is formed in the punch die. The compound die rigid waste ejecting mechanism further comprises a push rod, wherein the push rod is made of Q235 steel, the push rod is matched with the punching type hole in a gap mode, the upper end of the push rod is connected with a push board, the push board is connected inside the upper die seat in a removable mode, a hit rod is arranged on the push board, the hit rod is matched with the die shank in a gap mode, the upper end of the hit rod stretches out the upper surface of the die shank, and a part of the hit rod is connected with a nut in a threaded mode, wherein the part stretches out the die shank. The compound die rigid waste ejecting mechanism is capable of discharging waste automatically after punching each time, and therefore the problem that the waste is accumulated so as to blow up the punch die is avoided, processing cost is reduced, and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of mold component, relates in particular to a kind of compound die rigidity waste material ejecting mechanism.
Background technology
Punching press is at room temperature to utilize the mould that is installed on the forcing press that material is exerted pressure, and makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.Diel is the requisite technological equipment of punching production, is technology-intensive product, and it can carry out the processing and forming such as punching, blanking, bending and pull and stretch.The quality of stamping parts, production efficiency and production cost etc. have direct relation with Design of Dies and manufacturing.For the compound die that blanking and punching can be finished simultaneously, waste materials in stamping is easy to be stuck in the punching hole type hole of punch-die, if the untimely discharge of waste material; then may pile up the spalling punch-die; must shutdown maintenance or change punch-die, increased processing cost, reduced operating efficiency.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of compound die rigidity waste material ejecting mechanism, can automatically discharge waste material after each punching press, has avoided waste from stacking spalling punch-die, has reduced processing cost, has improved operating efficiency.
The technical solution of the utility model is: a kind of compound die rigidity waste material ejecting mechanism, comprise upper bolster, die shank and punch-die, punch-die is fixedly connected on the upper bolster lower surface, have the punching hole type hole on the punch-die, also comprise push rod, described push rod adopts the Q235 steel to make, push rod cooperates with the punching hole type interporal lacuna, the push rod upper end is connected with push pedal, push pedal is movably connected in the upper bolster, is provided with in the push pedal to make bar, beats bar and die shank matched in clearance, the die shank upper surface is stretched out in its upper end, beats part that bar the stretches out die shank nut that has been threaded.
As preferably, upper bolster adopts the Q235 steel to make, and punch-die adopts the GCr15 steel to make, and punch-die is connected with upper bolster by fixed head, is provided with backing plate between punch-die and the upper bolster, and described backing plate adopts 45 steel to make.
As preferably, die shank presses fit in the upper bolster, and die shank adopts 45 steel to make, and the upper bolster lower surface has groove, and push pedal is positioned at groove and can be mobile at groove, and the push rod lower surface is the conical surface.
The beneficial effects of the utility model are: punch-die punching hole type of the present utility model is provided with push rod in the hole, when upper bolster moves down, push rod relative punch-die under the effect of piercing punch moves, and piercing punch is finished punching, when moving on the upper bolster, crossbeam in the press ram presses down makes bar, by push pedal, push rod waste material is released, avoided waste from stacking spalling punch-die, needn't frequently keep in repair or change punch-die, reduce processing cost, improved operating efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, punch-die; 2, fixed head; 3, backing plate; 4, upper bolster; 5, die shank; 6, nut; 7, make bar; 8, push pedal; 9, push rod.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of compound die rigidity waste material ejecting mechanism comprises upper bolster 4, die shank 5 and punch-die 1, and in the present embodiment, as preferably, die shank 5 presses fit in the upper bolster 4, and die shank 5 adopts 45 steel to make.Punch-die 1 is fixedly connected on upper bolster 4 lower surfaces, has the punching hole type hole on the punch-die 1, also comprises push rod 9, and described push rod 9 adopts the Q235 steel to make good combination property, long service life.Push rod 9 cooperates with the punching hole type interporal lacuna, in the present embodiment, has two punching hole type holes on the punch-die 1, is respectively arranged with push rod 9 in it.Push rod 9 upper ends are connected with push pedal 8, and push pedal 8 is movably connected in the upper bolster 4, in the present embodiment, as preferably, upper bolster 4 lower surfaces have groove, and push pedal 8 is positioned at groove and can be mobile at groove, when push pedal 8 was positioned at the groove end face, the lower surface of push rod 9 was positioned at the punching hole type hole.Be provided with in the push pedal 8 and make bar 7, beat bar 7 and die shank 5 matched in clearance, die shank 5 upper surfaces are stretched out in its upper end, beat part that bar 7 stretches out die shank 5 nut 6 that has been threaded, and nut 6 can prevent that dozen bar 7 from deviating from from die shank 5.
In the present embodiment, as preferably, upper bolster 4 adopts the Q235 steel to make good combination property, long service life.Punch-die 1 adopts the GCr15 steel to make, and intensity is high, and is not fragile.Punch-die 1 is connected with upper bolster 4 by fixed head 2, is provided with backing plate 3 between punch-die 1 and the upper bolster 4, and described backing plate 3 adopts 45 steel to make.The impact of 1 pair of upper bolster 4 of punch-die when backing plate 3 can reduce punching press, the service life of prolongation upper bolster 4.In the present embodiment, push rod 9 passes backing plate 3 and is connected with push pedal 8.Push rod 9 lower surfaces are the conical surface, the release of more convenient waste material.
Operation principle of the present utility model is: when upper bolster 4 moves down, push rod 9 relative punch-die 1 under the effect of piercing punch moves, piercing punch is finished punching, when moving on the upper bolster 4, crossbeam in the press ram presses down makes bar 7, by push pedal 8, push rod 9 waste material is released, avoided waste from stacking spalling punch-die 1.
