Embodiment tri-
Be a kind of arrangements for automotive doors upper rail as shown in figure 12, also be that cross section is the slot stick of concave shape, car door upper rail generally adopts metal belting through rolling technology moulding continuously, forms the groove 1A being surrounded by epipleurite 1B, bottom land 1C, hypopleurite 1D, and cuts off online; Often install and need for it, the car door upper rail after cut-out need to carry out die-cut operation to its end, lateral plate; The end that its medial end portions is punched to epipleurite 1B, bottom land 1C, hypopleurite 1D different length cuts off, and lateral plate is punched to breach or punching; Before die-cut, its end is as the left end of Fig. 2, dotted line with left part part for needing cut-out, after die-cut as shown in figure 12, end needs cut-out to comprise to be positioned at epipleurite 1B end, bottom land 1C end, the hypopleurite 1D end of groove 1A, bottom land 1C end excision sheet is angle square sheet as shown in the figure, excision sheet in epipleurite 1B end be and isometric of angle square sheet lengthy motion picture, and hypopleurite 1D end is excised sheet and is and the lengthy motion picture such as angle square sheet short-movie.Die-cut 6 breach 1E that are positioned at its hypopleurite 1D and 2 the circular hole 1F that are located thereon lateral plate 1B of comprising of lateral plate.
The slot stick Special punching cutting apparatus of the present embodiment three is for the multi-faceted combination Special punching cutting apparatus of arrangements for automotive doors upper rail as shown in figure 12, completes 6 breach 1E of two ends, hypopleurite 1B of above-mentioned car door upper rail and the same machine of 2 circular hole 1F of epipleurite is die-cut on this blanking units.Below also car door upper rail is called to slot stick workpiece 1.
The slot stick Special punching cutting apparatus of the present embodiment three is as shown in Figure 13, Figure 14, and wherein, Figure 13 does not place slot stick workpiece 1, and Figure 14 has placed slot stick workpiece 1, when die-cut, slot stick workpiece 1 is placed in side direction setting mode.Compared with embodiment, by car door upper rail need to as shown in figure 12, the end punching mechanism of the present embodiment blanking units is set to symmetrical a pair of, is symmetrically distributed in the two ends place of workpiece to be installed by the length of slot stick workpiece 1, and hypopleurite punching mechanism is set to 6 arranged side by side; Inside workpiece rest block 4, workpiece, block 5 all need to be set to multiplely by Workpiece length, and workpiece clamping mechanism is set to symmetrical 2, lay respectively at end punching mechanism before.The slot stick Special punching cutting apparatus of the present embodiment three also comprises epipleurite punching mechanism, and this epipleurite punching mechanism comprises the 4th oil cylinder 28 being fixedly mounted on shelf 3, die-cut the 3rd punching cutter 29 from top to bottom being driven by the 4th oil cylinder 28; The same appearance cutter breach of offering for holding die-cut the 3rd descending punching cutter 29 in relevant position at base 24 and the seat of honour 25.
In addition, due to the effect of chucking power and flush shear force, after die-cut operation completes, slot stick workpiece 1 can be adsorbed in workpiece rest block 4, and manual pickup often acquires a certain degree of difficulty, and efficiency is very low; In order to facilitate pickup, improve operating efficiency; As shown in Figure 13, Figure 14, the slot stick Special punching cutting apparatus of the present embodiment three is also symmetrical arranged on workpiece clamping mechanism side the Nuo Jian mechanism of after two covers complete for die-cut operation, slot stick workpiece 1 being moved out from clamping position.Gai Nuojian mechanism specifically as shown in figure 15, comprise that the vertical mode of putting of level is fixedly mounted on the second cylinder 30 on base plate 2, be shelved on the slide block 31 being fixedly connected with on base plate 2 and with the piston rod of the second cylinder 30, place the 3rd cylinder 32 being fixedly mounted on slide block 31 vertically, be positioned under slot stick workpiece 1 and the tray 33 being fixedly connected with the 3rd cylinder 32 piston rods, these tray 33 ends arrange hook 34 protruding upward, are formed for shelving the groove 35 of slot stick workpiece 1.
Die-cut operation process and embodiment bis-are basic identical, are specially:
1, location: taking shown in Figure 13 above as operating position, slot stick workpiece 1 is placed on above each workpiece rest block 4 in the setting of side direction shown in Figure 14 mode, block 5 inside the groove bottom 1C of its groove 1A and each workpiece is offseted, slot stick workpiece 1 left end and block 36 offset, and slot stick workpiece 1 hypopleurite contact surface matches with 27 upper surfaces of respectively inserting.
2, clamping: the second oil cylinder 14 that simultaneously starts 2 workpiece clamping mechanism, drive its slide plate 15 inwardly to slide along guide rail 13, outside workpiece, fixture block 6 inwardly slides with contiguous block 21 thereupon, outside workpiece, fixture block 6 is encountered the rear continuation of slot stick workpiece 1 and is started the second oil cylinder 14 to power, forms inside and outside chucking power together with block inside workpiece 5; Workpiece top briquetting 7 also inwardly slides with contiguous block 21, and the first cylinder 16 being fixedly mounted on slide plate 15 also inwardly slides with slide plate 15; Meanwhile, start the first cylinder 16 on slide plate 15, drive connecting rod 17 inwardly to slide, and act on through its lower inclined plane 18 and the ramp 19 of workpiece top briquetting 7, make workpiece top briquetting 7 descending and push down slot stick workpiece 1 along column 20.
3, end is die-cut: start the first oil cylinder 8 of 2 end punching mechanisms simultaneously, drive its first punching cutter 9 to slide along the guide groove 23 of guiding slot holder 22, the disposable both ends excision completing slot stick workpiece 1 of the first punching cutter 9 at two ends.Starting in the first oil cylinder 8 or front and back, start the 3rd oil cylinder 10 and the 4th oil cylinder 28, drive the second punching cutter 11 and the 3rd punching cutter 29 die-cut from top to bottom, complete die-cut to 6 of slot stick workpiece 1 hypopleurite 1D 2 circular hole 1F that rush breach 1E and epipleurite 1B thereof.
4, loosen pickup: the second oil cylinder 14 of 2 workpiece clamping mechanism of reverse starting, the first oil cylinder 8 of 16 and 2 end punching mechanisms of the first cylinder, its piston rod rollback separately resets, outside workpiece, fixture block 6 resets with contiguous block 21 thereupon, the compression spring effect next time spring-go position of workpiece top briquetting 7 in circular pit 37, and outwards slide and leave slot stick workpiece 1 top, end with contiguous block 21, slide plate 15; At this moment start the 3rd cylinder 32 of Nuo Jian mechanism, the slot stick workpiece 1 of being about to be positioned at its groove 35 tops on tray 33 lifts; Start its second cylinder 30, slot stick workpiece 1 outwards slides, thereby slot stick workpiece 1 is moved out to the position that is easy to manual pickup with tray 33 and the 3rd cylinder 32, slide block 31 simultaneously; At this moment operator can take off all die-cut slot stick workpiece 1 easily, and namely the present embodiment three starts said car door upper rail.
In addition, present specification middle left and right, the alleged orientation such as forward and backward, only statement is convenient in the expression of present patent application figure relatively, does not form restriction of the present utility model.
