Said oblique impact structure 82 comprises: slide block 821, punch case 822 and punch 823.Said punch 823 is fixed in the punch case 822, is arranged in the discharging structure 84 through punch case 822.Slide block 821 is fixed in the patrix 70, particularly is fixed in the upper mould fixed plate 803, thus can be with patrix 80 rectilinear motion up and down reciprocatingly.Why say that it is a slide block 821; Be because it is provided with an oblique T shape chute; One end and the T shape chute of said punch case 822 are suitable; With the rectilinear motion up and down reciprocatingly of slide block 821, convert the oblique impact motion of punch 823 into, thereby can on inclined-plane 12, go out beveled aperture 13 perpendicular to lid product inclined-plane 12.The lid product of this specific embodiment processing; Three beveled aperture 13 have been symmetrically distributed on its conical inclined surface 12; Therefore oblique impact structure 82 also has three covers accordingly, and 120 degree are arranged at interval respectively, thereby can once on inclined-plane 12, go out three beveled aperture 13. shown in Figure 2
Said discharging structure 84 plays discharging and the auxiliary effect that compresses, and concrete structure comprises: stripper 841, discharging cover plate 842 and stripper insert 843.Stripper 841 is fixedly connected with the discharging cover plate 842 that is positioned at its top, and stripper is inserted and 843 is embedded among stripper 841 and the discharging cover plate 842.Aforementioned punch case 822 and punch 823 just are arranged on stripper and insert among 843, and punch case 822 can be with punch 823 relative strippers to insert 843 to slide, move thereby accomplish oblique impact.This kind structure not only can be simplified the structure of discharging structure 84, reduces difficulty of processing; And helping keeping in repair punch case 822 and punch 823, stripper inserts 843 if wearing and tearing only need to change stripper and insert 843, and need not change whole discharging structure 84.
Said down elastic construction 83 is used to cooperate discharging structure 84 dischargings, and is that said oblique impact structure is extracted from the beveled aperture of going out power is provided at the moulds open initial stage.Be provided with in the said counterdie and hold the accommodation hole of elastic construction 83 down; Said down elastic construction 83 promptly is arranged in the described accommodation hole, and down the lower end elastic reaction of elastic construction 83 in counterdie 81, the upper end then elastic reaction in strip.
Following elastic construction has many covers, and the elastic construction concrete structure comprises under every cover: following discharging push rod 831, discharging spring 832 and lower spring lid 833 down.Be provided with the through hole that runs through up and down in the counterdie 81, following elastic construction 83 promptly is arranged in the said through hole.The upper end of following discharging spring 832 through said down discharging push rod 831 elastic reactions in the lower surface of strip; The lower end of following discharging spring 832 withstands on the upper surface of lower spring lid 833, and lower spring lid 833 is fixedly connected with counterdie 81, from the said through hole of lower end closed.
Last elastic construction 85 is slightly different with following elastic construction, and it comprises: upper spring lid 851, loading and unloading material spring 852, loading and unloading material push rod 853 and attachment screw 854.Like Fig. 4 and shown in Figure 5, the lower end of attachment screw 854 is fixedly connected with stripper 841, and the upper end then is connected with the lower end of loading and unloading material push rod 853.After loading and unloading material push rod 853 runs through discharging cover plate 842, the lower end that loading and unloading material spring 852 is withstood in its upper end; And upper spring lid 851 is withstood in the upper end of loading and unloading material spring 852, and is enclosed in the patrix 80 by upper spring lid 851.
During the mould mould closes, patrix 80 is being with oblique impact structure 82 and discharging structure 84 to move downward, when as shown in Figure 5, and discharging structure 84 contact counterdies 81 and stop motion is pressed on strip between stripper 841 and the die block 813 simultaneously.After this patrix 80 continues to move downward and carries out matched moulds; Loading and unloading material push rod 853 acts on loading and unloading material spring 852, and loading and unloading material spring 852 is further compressed; The elastic force of loading and unloading material spring 852 then acts on discharging structure 84 through loading and unloading material push rod 853 and attachment screw 854, thereby plays the auxiliary effect that compresses.Simultaneously, patrix 80 drives punch case 822 with inclined-plane 12 motions of punch 823 perpendicular to lid product blank through slide block 821, thereby on inclined-plane 12, goes out beveled aperture 13.This moment is as shown in Figure 4, and mould is closed fully.
During moulds open, patrix 80 begins to move upward, and this moment, discharging structure 84 was also not moving, but punch 823 begins from the beveled aperture of going out 13, to withdraw from.Arrive then when shown in Figure 5, stripper 841 beginnings separate with die block 813, move on the net with patrix, open fully until mould.In this process, lid product blank elastic construction 83 down, under the cooperation of elastic construction 85 and discharging structure 84, deviate from and accomplish discharging from stripper 841 and die 814, so just accomplished an operation cycle.After this, be connected lid product blank on the strip and can be sent to next station with strip and carry out pre-cutting,
What need additionally stress is that because the moulds open initial stage, patrix 80 begins to move upward; This moment, discharging structure 84 was also not moving; But punch 823 need withdraw from from the beveled aperture of going out 13, and the phenomenon that then possibly exist punch 823 to be difficult to extract is especially for for thicker strip.This is that punch 823 still is in the beveled aperture 13 because of the die sinking initial stage, but but can't move obliquely; Can only be drawn vertically upward by force by patrix, the result causes punch 823 to be broken or the edge of a knife of die 814 is scrapped by kibe, and the cost of scrapping a punch 823 is 149.94 yuan; The cost of scrapping a die 814 is 1151.9 yuan, adds form removal tool, the time of renewal part and the expense of shutting down; Just not saying delivered product on time; Once the product of this batch is just in vain at last so as long as mould is bad, badly just can't regain one's original capital for twice, but also must do.Conventional solution is below single punch 823, with spring punch 823 to be resetted, but in the limited space of the progressive die, wants bigger brute spring is installed, and possibility is little, and when spring lost efficacy and also can't confirm.And if spring force is not enough; Then certainly existing punch 823 can't pull out and the phenomenon of mold damage smoothly; And find that through overtesting this kind method not only can't meet design requirement, and production efficiency also can't be satisfied the demand only to reach 15～20/minute.
In this specific embodiment, the withdrawal force of punch 823 is from following discharging structure 83, particularly from following discharging spring 832.The following discharging spring 832 that in fact 6 brute forces are arranged in this specific embodiment; The continuous stamping die of cover product of this specific embodiment of experiment proof punch 823 never occurred and pulled out the phenomenon of not coming out; Production efficiency has also reached 30～40/minute, thereby has obtained better economic benefits.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
