Described 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 fixedlyed 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, thereby finish the oblique impact action.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.
Described down elastic construction 83 is used to cooperate discharging structure 84 dischargings, and extracts from the beveled aperture of going out for described oblique impact structure at the mould initial stage of opening power is provided.Be provided with in the described counterdie and hold the accommodation hole of elastic construction 83 down; Described 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, following discharging spring 832 and lower spring lid 833.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 described through hole.The upper end of following discharging spring 832 by described 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 fixedlyed connected with counterdie 81, from the described 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.As shown in Figure 4 and Figure 5, fixedly connected with stripper 841 in the lower end of attachment screw 854, 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.
When the mould mould was closed, patrix 80 had been with oblique impact structure 82 and discharging structure 84 to move downward, to as shown in Figure 5 the time, 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 by 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 by slide block 821, thereby goes out beveled aperture 13 on inclined-plane 12.This moment, mould was closed fully as shown in Figure 4.
When mould was opened, patrix 80 began to move upward, and this moment, discharging structure 84 was also not moving, but punch 823 begins to withdraw from from the beveled aperture of going out 13.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 finish discharging from stripper 841 and die 814, so just finished a working cycles.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 additional emphasize is that because mould is opened the 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 may exist punch 823 to be difficult to extract then is especially for for thicker strip.This is because the die sinking initial stage; punch 823 still is in the beveled aperture 13; 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; the cost of scrapping a punch 823 is 149.94 yuan; the cost of scrapping a die 814 is 1151.9 yuan; add and shut down the form removal tool; the time of renewal part and expense, 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; just can't regain one's original capital, but also must do for bad twice.Conventional solution is with spring punch 823 to be resetted below single punch 823, but wants bigger brute spring is installed in the limited space of the progressive die, and possibility is little, and when spring lost efficacy and also can't determine.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 that experimental results show that this specific embodiment 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 be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
