Described upper die component mainly is made up of top mold frame 35, die shank 10, punch frame 1, chamfering drift 2, convex mould base 3, jet-bedding punch 4, dividing plate I5, pre-profiling patrix 6, dividing plate II7 and typing patrix 8.Described die shank 10 upper ends are fixedly connected in the hole of punch press ram 9, die shank 10 bottoms and top mold frame 35 upper ends are screwed, punch frame 1 is fixedly connected on top mold frame 35 belows downwards, chamfering drift 2, convex mould base 3, jet-bedding punch 4, dividing plate I5, pre-profiling patrix 6, dividing plate II7 and typing patrix 8 all are installed in the inner chamber of punch frame 1 from left to right successively in proper order, and withstand fixing by the screw of punch frame 1 side.
Described membrane module down is mainly by mould bases 26, base plate 25, die frame 24, lower die 33, die gusset 32, dividing plate III31, adjustment piece 30, limited block 29, typing counterdie 27, baffle plate 28 and stripper 11 are formed down.Described mould bases 26 down upwards is fixedly connected on the punch press platform 34, following mould bases 26 places under the top mold frame 35, base plate 25 upwards is fixedly connected on down mould bases 26 tops, die frame 24 upwards is fixedly connected on base plate 25 tops, lower die 33, die gusset 32, dividing plate III31, adjustment piece 30 (having two), limited block 29 (having two), typing counterdie 27 and baffle plate 28 (having two) all are installed in the inner chamber of die frame 24 from left to right successively in proper order, and withstand fixing by die frame 24 at two screws of and arranged on left and right sides.Stripper 11 is installed in die frame 24 upper ends.
The described pay-off that feeds automatically is made up of block hitting seat 14, block hitting 20, guide rod seat 17, guide rod 16, turning rolls 21, moving tooth pawl 12, moving tooth crowfoot 13, support spring 15, roller 22, spring 18 and ejector pin 19.Block hitting seat 14 is fixedly connected on top mold frame 35 right sides to the right, and block hitting 20 is fixedly connected on downwards on the block hitting seat 14; Guide rod seat 17 is fixedly connected on the die frame 24 upper right end faces, pass guide rod seat 17 in the middle of the guide rod 16 (two), guide rod 16 right-hand members and four nuts of turning rolls 21 usefulness also fasten, guide rod 16 left ends are fixedlyed connected with moving tooth crowfoot 13, like this, moving tooth crowfoot 13 is fixedlyed connected with turning rolls 21 with guide rod 16 and is integral, in the guide hole of guide rod seat 17, can left and rightly move, in addition, in the middle of turning rolls 21 left ends, protrude left and be connected with ejector pin 19, be equipped with spring 18 in guide rod seat 17, ejector pin 19 left ends insert in the guide rod seat 17 and offset with spring 18 right-hand members.Moving tooth pawl 12 is fixed on the moving tooth crowfoot 13 by bearing pin, and support spring 15 usefulness one bearing pin is fixed on the moving tooth crowfoot 13 of moving tooth pawl 12 tops, matches with the motion mode of moving tooth pawl 12, gives moving tooth pawl 12 downward certain pressure.Roller 22 usefulness bearing pins are connected in the groove on turning rolls 21 right sides.
Operation principle and operating process:
At first, outer sprocket blank band shown in Figure 1 is pierced in the groove of die frame 24 upper surfaces of stripper 11 belows, block (straight tooth blank can't by), starting punch press motor, driving stroke of manual punch press to limited block 29.When punch press ram 9 moves down into minimum point, jet-bedding punch 4 inserts in the lower die 33 of its below, on the blank band, go out " one " word groove of separated 1mm in, at jet-bedding punch 4 left front phase next but two tooth pitches chamfering drift 2 has been installed, chamfering drift 2 extrudes 90 ° of bell-mouthed pits in blank band upper surface, this pit upper width greater than " one " word groove width 0.6mm about, the pit bottom width less than " one " word groove width 0.1mm about.When punch die work for the third time the time, jet-bedding punch 4 is gone out " one " word groove and is fitted like a glove with the horn mouth pit of going out in advance.Like this, " once " word groove both sides suitable for reading leave 0.3 * 45 ° chamfering.The left side bearing in lower die 33 jet-bedding groove " " word chambeies to the right two tooth pitches limited block 29 is installed (limited block 29 is had two, and adjusting piece 30 just in time is a tooth pitch thickness, the width of dividing plate III31 thickness and " one " word groove and equal a tooth pitch.), pre-profiling patrix 6 drops on two and adjusts in the middle of the piece 30, (pre-profiling patrix 6 thickness just in time are tooth pitches) matches with the typing counterdie 27 of below, tooth pitch length of blank band is pressed into than outer big slightly " U " shape of sprocket " U " type opening of semi-finished product, just at the right time can be in the middle of two limited blocks 29 below by, so stroke blank band tooth pitch that can only advance each time, guarantee that outer sprocket semi-finished product size is unified, after passing through limited block 29, typing patrix 8 matches with typing counterdie 27, extrudes standard " U " shape of outer sprocket.Rise when resetting at punch press ram 9, stripper 11 blocks the blank band and catches up with, and the blank band is stayed in the groove of upper surface of die frame 24.After a driving stroke is intact, continue manual feeding, manual punch press descends the step driving stroke.Manual more than 22 times continuously, the outer sprocket of stamping-out moulding enters moving tooth pawl 12 workspaces, the work of practicable automatic stamping-out feeding.
Automatically feed the operation principle of pay-off:
When punch press ram 9 is displaced downwardly to minimum point, the block hitting 20 on block hitting seat 14 right sides moves down simultaneously, block hitting 20 is pressed onto roller 22, because block hitting 20 is 30 ° of inclined-planes with roller 22 contact-making surfaces, the following turning rolls 21 of ramp effect to the left front promote to be a bit larger tham a tooth pitch from, moving tooth pawl 12 moves to the left front synchronously, and moving tooth pawl 12 is subjected to the pressure of support spring 15, and the pawl tip is fallen in " one " word groove of outer sprocket; Punch press ram 9 rises and replys, and block hitting 20 breaks away from roller 22, and turning rolls 21 is moved right by the thrust of spring 18, and moving tooth pawl 12 drives outer sprocket semi-finished product 23 and the blank band moves right together.Because the effect of limited block 29, make outer sprocket semi-finished product and the blank band tooth pitch that can only move to right, punch press automatically under the work realization feed feeding punching process process automatically.
