The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Referring to Fig. 1, a kind of flanging bore mould material-bouncing prevention device, comprises flange drift 3, and flange drift 3 is fixedly mounted on patrix 1, and flange drift 3 is provided with punching portion 31 and turn-up portion 32, as shown in Figure 4.Also comprise counterdie plunger tip 4 and holddown spring 5, counterdie plunger tip 4 is slidably mounted in the installing hole of counterdie 2, and counterdie plunger tip 4 one end are provided with the cutting edge 41 suitable with punching portion 31, and the other end is connected with holddown spring 5.
During original state, holddown spring 5 holds out against counterdie plunger tip 4, during punching press, the punching portion 31 of flange drift 3 and the cutting edge 41 of counterdie plunger tip 4 complete the punching operation of workpiece, and as shown in Figure 2, punching portion 31 enters cutting edge 41, waste material is poured in cutting edge 41, waste material is departed from from workpiece; The turn-up portion 32 of flange drift 3 contacts with counterdie plunger tip 4 afterwards, overcomes the elastic force of holddown spring 5, promotes counterdie plunger tip 4 downwards, and counterdie plunger tip 4 is moved in installing hole, and the installing hole of turn-up portion 32 and counterdie 2 coordinates the overturning process that starts workpiece.After flange completes, patrix 1 departs from counterdie 2, and counterdie plunger tip 4 is got back to original position under the effect of holddown spring 5.
As shown in Figure 3, be axially arranged with the centre bore 42 that connects counterdie plunger tip 4 in counterdie plunger tip 4, centre bore 42 is communicated with cutting edge 41, centre bore 42 makes waste material pass through cutting edge 41 to depart from, depart from counterdie plunger tip 4 and counterdie 2, make waste material break away from moulds, prevent that waste material from impacting the work of mould.Centre bore 42 diameters are greater than the diameter of cutting edge 41, are convenient to dropping of waste material.
Holddown spring 5 is arranged in the installing hole of counterdie 2 by plug screw 6 with holes, easy accessibility, and dropping of waste material is convenient in the hole on plug screw 6 with holes.
Counterdie plunger tip 4 is provided with block 43, is provided with the step of positive stop 43 in the installing hole of counterdie 2, and when block 43 contacts with step, the upper surface of counterdie plunger tip 4 is concordant with counterdie 2 upper surfaces.When initialization state, holddown spring 5 holds out against counterdie plunger tip 4, and block 43 and step play position-limiting action, and now the upper surface of counterdie plunger tip 4 is concordant with counterdie 2 upper surfaces, has both been convenient to the placement of workpiece on counterdie 2, and counterdie plunger tip 4 can not eject workpiece; Work support contacts with the cutting edge 41 of counterdie plunger tip 4 simultaneously, is convenient to the punching of flange drift 3.
Holddown spring 5 is utmost point heavy burden die springs, adopts dark brown spring, can bear larger load.
Punch press top shoe drives patrix 1 running, and flange drift 3 is gone out hole flanging downwards, and the logical counterdie plunger tip 4 of waste material drops, and through dark brown spring and by plug screw 6 with holes, drops and realizes flanging bore and be not with waste material.
Adopt after above-mentioned structure, by changing mould structure, solve flange pore area waste material, impression, distortion simultaneously, ftracture, skid and the quality problem such as attractive in appearance.After utilizing counterdie plunger tip 4 that pre-punched hole waste material is dropped by centre bore 42, carry out again hole flanging, avoid jump-scrap cause impression and quality bad.Save pre-punched hole operation, reduce disconnected drift risk, cost-saving, the sheet metal component quality problem that effectively pre-anti-tripping waste causes.Can be used for all moulds with flanging bore operation.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
