The specific embodiment

Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.

As Figure 1-5, die-cut assembly of the present invention comprises mounting bracket 1, and be fixed on the die-cut support 3 on mounting bracket 1, this die-cut support 3 comprises upper horizontal support 31, lower horizontal support 32 and connects the vertical support frame 33 of upper horizontal support 31 and lower horizontal support 32, this vertical support frame 33 is positioned at a side of this upper horizontal support 31 and lower horizontal support 32, and described vertical support frame 32 fixes with mounting bracket 1.Between this upper horizontal support 31 and lower horizontal support 32, near a side of vertical support frame 33, be vertically connected with a guide post 28, the two ends up and down of this guide post 28 are mounted on respectively on upper horizontal support 31 and lower horizontal support 32.On this guide post 28, by guide pin bushing 29, be connected with a plate 30, 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 is also 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 top of this upper horizontal support 31 is fixed with an oil cylinder 26, and this oil cylinder 26 is as the drive source of die-cut assembly, and the output shaft of this oil cylinder arranges the top that is fixedly connected on this connecting plate 30 downwards.This connecting plate 30 can be moved up and down along this guide post 28 by the driving of this oil cylinder 26.

The centre of described convex mould base 18 has a projection 181 to downward-extension, the below of this convex mould base 18 is also 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 and compact heap 13 can move up and down with respect to convex mould base 18 below this convex mould base 18.On this briquetting backing plate 15, have the groove 151 matching with this projection 181, this groove 151 and projection 181 are for limiting this briquetting backing plate 15 and compact heap 13 position upwards.As shown in Figure 1, in the both sides of this convex mould base 18, there is respectively a guide pillar 35, the upper end of this guide pillar 35 is inserted this punch cushion block 19 and convex mould base 18 and is fixed on punch cushion block 19, the lower end of this guide pillar 35 is fixed with a nut 37 through the lower end of this briquetting backing plate 15 and this guide pillar 35, this nut 37 is positioned at the below of this briquetting backing plate 15, and therefore 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 on 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 described 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 He Gai hole, upper end 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.

On this convex mould base 18, be also fixed with a punch 12 straight down, this punch 12 is through the projection 181 of this convex mould base 18 and convex mould base 18 belows, and through 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 is vertically inserted with of this punch 12.As shown in Figure 5, 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 upwards, i.e. top step surface 1921 and below step surface 1922, the upper end of this detection pin 11 is limited in this below step surface, in the connecting hole 192 of below step surface 1922 tops in this connecting hole 192, be inserted with a push rod 21, the bottom of this push rod 21 has the flange collar 211 that a diameter is larger, and the flange collar 211 of this push rod 21 matches with the upper end of this detection pin 11.In the upper port of this connecting hole 192, be connected with a cock body, in the present embodiment, preferably, the upper port of this connecting hole 192 is that large aperture port forms described top step surface, this large aperture port is screw, cock body is the plug screw 23 being threaded in screw, this push rod 21 can along this plug screw 23 move up and down and the top of this push rod 21 extended in plug screw 23.In the outside of this push rod 21, cover has a back-moving spring 22, the two ends of this back-moving spring 22 to be butted on respectively in the flange collar 211 of the lower surface of this plug screw 23 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.On this punch cushion block 19, there is an interconnection 193 and is communicated to the top of this connecting hole 192, in this interconnection 193, be inserted with a switch 17, this switch 17 is conventional formula microswitch (also can adopt other inductive switch), it is fixed on this punch cushion block 19, and its medial extremity matches with the top of this push rod 21 after laterally extending.Moving downward along with punch cushion block 19 after detecting the below of pin 11 to prop up workpiece a to be processed, this detection pin 11 moves upward along this connecting hole 192, and then the top of this push rod 21 is while touching the medial extremity of this switch 17, can think die-cut beginning, after detection pin 11 is along with downward die-cut this workpiece to be processed of punch 12, when punch cushion block 19 starts to move upward, this detection pin 11 is because the reset force of this back-moving spring 22 moves downward, 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, more greatly improved production efficiency.

On described lower horizontal support 32, be fixed with a die socket 14, on this die socket 14, the position corresponding with this punch 12 is provided with die 16, and this die socket 14 is with this punch 12 and detect pin 11 and match, this punch 12 and detect pin 11 and insert when die-cut.Workpiece to be processed is just positioned on this die socket 14.In the both sides of this die-cut support 3, there is respectively side plate 38, the parts such as described punch cushion block 19, convex mould base 18 are all surrounded between two blocks of side plates 38.

Die-cut assembly of the present invention can utilize compact heap that workpiece to be processed is compressed before die-cut, make elongated and there is flexible workpiece to be machined and can fit with the locating surface of workbench well, 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.
