The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1-5; Die-cut assembly of the present invention comprises mounting bracket 1; And be fixed in the die-cut support 3 on the mounting bracket 1; This die-cut support 3 comprises upper horizontal support 31, lower horizontal support 32 and the vertical support frame 33 that connects upper horizontal support 31 and lower horizontal support 32, and this vertical support frame 33 is positioned at a side of this upper horizontal support 31 and lower horizontal support 32, and said vertical support frame 32 fixes with mounting bracket 1.Between this upper horizontal support 31 and the lower horizontal support 32, vertically be connected with a guide post 28 near a side of vertical support frame 33, the two ends up and down of this guide post 28 are mounted on respectively on upper horizontal support 31 and the lower horizontal support 32.Be connected with a plate 30 through guide pin bushing 29 on this guide post 28, this connecting plate 30 is horizontally disposed with, and can move up and down along this guide post 28, and this guide post 28 is positioned at the rear side of this connecting plate 30.The below of this connecting plate 30 is fixedly connected with a punch cushion block 19, and this punch cushion block 19 also is placed on this guide post 28, strengthens the intensity of this connecting plate 30, and the below of this punch cushion block 19 is connected with convex mould base 18.The upper fixed of this upper horizontal support 31 has an oil cylinder 26, and this oil cylinder 2 is as the drive source of die-cut assembly, and the output shaft of this oil cylinder is provided with the top that is fixedly connected on this connecting plate 30 downwards.This connecting plate 32 can be moved up and down along this guide post 28 by the driving of this oil cylinder 26.
The centre of said convex mould base 18 has one to the projection that extends below 181; The below of this convex mould base 18 also is provided with a briquetting backing plate 15 and is positioned at the below of briquetting cushion block 15 and the compact heap 13 that briquetting backing plate 15 fixes, and this briquetting backing plate 15 can move up and down with respect to convex mould base 18 below this convex mould base 18 with compact heap 13.Have the groove 151 that is complementary with this projection 181 on this briquetting backing plate 15, this groove 151 and projection 181 are used to limit the position that this briquetting backing plate 15 and compact heap 13 make progress.As shown in Figure 3; Both sides at this convex mould base 18; Have a guide pillar 35 respectively, this punch cushion block 19 is inserted with convex mould base 18 and be fixed on the punch cushion block 19 in the upper end of this guide pillar 35, and the lower end that this briquetting backing plate 15 and this guide pillar 35 are passed in the lower end of this guide pillar 35 is fixed with a nut 37; This nut 37 is positioned at the below of this briquetting backing plate 15, so this briquetting backing plate 15 can move up and down along with this guide pillar 35 with this compact heap 13.The upper end of this guide pillar 35 is inserted in the hole 191 of this punch cushion block 19; This hole 191 is a shoulder hole; Have a downward cascaded surface, a spring 36 is placed in this guide pillar 35 outsides, and the two ends of this spring 36 are butted on respectively on the upper surface of cascaded surface and said briquetting backing plate 15.Preferably, also have a guide pin bushing 34 between this briquetting backing plate 15 and this guide pillar 35, this guide pin bushing 34 is fixing with this briquetting backing plate 15, and the two ends of this spring 36 are butted on respectively on the cascaded surface in upper end and this hole 191 of this guide pin bushing 34.Therefore, this briquetting backing plate 15 can move up and down along with guide pillar 35 with this compact heap 13, and this spring 36 makes this briquetting backing plate 15 have the downtrend away from this convex mould base 18 with this compact heap 13.
Also be fixed with straight down a punch 12 on this convex mould base 18; This punch 12 passes the projection 181 of this convex mould base 18 and convex mould base 18 belows; And pass above-mentioned briquetting backing plate 15 and compact heap 13, be exposed to the below of this compact heap 13, the interior detection pin 11 that vertically is inserted with of this punch 12.As shown in Figure 7; The upper end of this detection pin 11 is inserted in the vertical connecting hole 192 of this punch cushion block 19; This connecting hole 192 has two step surfaces that make progress; Step surface 1921 and below step surface 1922 promptly, the upper end of this detection pin 11 is limited in this below step surface, is inserted with a push rod 21 in the connecting hole 192 of below step surface 1922 tops in this connecting hole 192; The bottom of this push rod 21 has the bigger protruding circle 211 of a diameter, and the protruding circle 211 of this push rod 21 matches with the upper end of this detection pin 11.Be connected with a cock body in the port of this connecting hole 192; In the present embodiment; Preferably, the port of this connecting hole 192 is that the large aperture port forms described top step surface, and this large aperture port is a screw; Cock body is the plug screw 23 that is threaded in the screw, and this push rod 21 can move up and down and the top of this push rod 21 can stretch out in plug screw 23 along this plug screw 23.Be with a back-moving spring 22 in the outside of this push rod 21, on the protruding circle 211 of the lower surface that the two ends of this back-moving spring 22 are butted on this plug screw 23 respectively and the bottom of this push rod 21.This plug screw 23 position in connecting hole 192 can be adjusted up and down, and then can adjust the spring force of this back-moving spring 22.This back-moving spring 22 makes the detection pin 11 of these push rod 21 belows have downtrend all the time.Has the top that an interconnection 193 is communicated to this connecting hole 192 on this punch cushion block 19; Be inserted with a switch 17 in this interconnection 193; This switch 17 is moving switch (also can adopt other inductive switch) for routine declines; It is fixed on this punch cushion block 19, and matches with the top of this push rod 21 after its medial extremity horizontal expansion.Moving downward after the below of detecting pin 11 props up workpiece a to be processed along with punch cushion block 19; This detection pin 11 moves upward along this connecting hole 192, and then the top of this push rod 21 is when touching the medial extremity of this switch 17, can think die-cut beginning; After detection pin 11 is along with punch 12 downward die-cut these workpiece to be processed; When punch cushion block 19 began to move upward, this detection pin 11 was because the reset force of this back-moving spring 22 moves downward, and this push rod 21 also falls after rise downwards; Do not contact the medial extremity of this switch 17, can judge that this die-cutly finishes.Utilize detection means such as detecting pin and switch, can effectively prevent the stagnation of die-cut assembly, also avoided the omission of hand inspection, improved production efficiency more greatly.
Be fixed with a die socket 14 on the said lower horizontal support 32, be provided with die 16 with these punch 12 corresponding positions on this die socket 14, this die socket 14 and this punch 12 with detect pin 11 and match, supply when die-cut this punch 12 and detect pin 11 and insert.Workpiece to be processed just is positioned on this die socket 14.In the both sides of this die-cut support 3, have side plate 38 respectively, parts such as described punch cushion block 19, convex mould base 18 all are surrounded between two blocks of side plates 38.
Die-cut assembly of the present invention can utilize compact heap will add worker's workpiece before die-cut and compress; Elongated and rubber-like workpiece to be machined can be well fitted with the locating surface of workbench; To guarantee that product can be by successfully die-cut; And guaranteed die-cut quality and die-cut stability, reduced labour intensity; Utilize detection means such as detecting pin and switch simultaneously, can effectively prevent the stagnation of die-cut assembly, avoid the omission of hand inspection, can further enhance productivity, reduce production costs.
