The specific embodiment

A kind of pawl utmost point red edge-cutting and hole-punching compound die carrier as shown in Figure 1, comprise the cope match-plate pattern 1 and the lower bolster 2 that are oppositely arranged up and down, and lower bolster 2 both sides, bottom surface are connected with two lower support seats 91,92 respectively.Described lower bolster 2 is fixed with the very hot forging blank 10 of pawl for placing shaping and it is carried out to edger 3 and the piercing punch 4 for the very hot forging blank 10 of pawl is carried out to red punching of red trimming on the one side of cope match-plate pattern 1.Described edger 3 use trim rings 31 are fixed by screws on edger holder 32, and this edger holder 32 is fixed by screws on lower bolster 2, and this edger 3 has a nib, and the very hot forging blank 10 of pawl just is placed on this nib.Described piercing punch 4 use pressing plates 41 are fixed by screws on punch holder 42, and this punch holder 42 is fixed by screws on lower bolster 2, and this piercing punch 4 stretches out from bottom to up the nib of edger 3 and is positioned at the central hole location of the pawl utmost point.Described cope match-plate pattern 1 is fixed with the corresponding punch-die 5 of nib of a shape, position and edger 3 on the one side of lower bolster 2, this punch-die 5 is fixed by screws on upper padding plate 52, this upper padding plate 52 is fixed by screws on cope match-plate pattern 1, have the mesopore 51 coaxial with piercing punch 4 on this punch-die 5, the aperture of the mesopore 51 of this punch-die 5 is greater than the diameter of piercing punch 4.

This mould bases also comprises ejecting mechanism, this ejecting mechanism comprises backing-out punch 61, ejector beam 62, drives die pad 63, adjustment screw 64 and ejection cylinder 65, described backing-out punch 61 is arranged in the nib of edger 3, and this backing-out punch 61 is connected and forms up and down by backing-out punch body 611 and backing-out punch connecting plate 612.Described ejector beam 62 vertically runs through lower bolster 2, backing-out punch 61 is aimed in its upper end, the be connected drive die pad 63 of horizontally set of its lower end, described ejection cylinder 65 is positioned at and drives die pad 63 belows, and the lower push rod 651 on ejection cylinder 65 pistons is upwards aimed at and is driven die pad 63.Described adjustment screw 64 is connected with the bottom surface of lower bolster 2 after running through drive die pad 63, and this adjustment screw 64 is used for controlling drive die pad 63 strokes.

Be provided with knockout rod 71 in the mesopore 51 of described punch-die 5, the upper end of this knockout rod 71 is connected with makes bar 72, and cope match-plate pattern 1 is stretched out in this dozen of bar 72 upper ends.

Described upper and lower template 1,2 is aimed at location by positioning sleeve 81 with locating dowel 82.

Operating process and principle: be used in conjunction with 150 tons of crank presses, cope match-plate pattern 1 is fixed on press ram, lower bolster 2 is fixed on press bench, when press ram during in uppermost position in fig-ure, backing-out punch 61 is in extreme lower position, during work, the very hot forging blank 10 of the pawl of die-forging forming is placed on the nib of edger 3 and locates, when moving down, press ram drives punch-die 5 descending, contacting red trimming with the very hot forging blank 10 of pawl starts, along with slide block continues descending, when pit bottom surface, the very hot forging blank 10 of pawl center contacts with piercing punch 4, red trimming finishes, red punching starts, now the very hot forging blank 10 of pawl carries out red punching under the effect of piercing punch 4 and punch-die 5, slide block is to after bottom dead center, red punching finishes, finally, press ram goes upward to after top dead center, ejection cylinder 65 actions, the up drive of lower push rod 651 drives die pad 63, ejector beam 62 and backing-out punch 61 eject the pawl utmost point in edger 3.Because pawl polar wind fan You Yu hole, plane exists, therefore the remaining piece that punching produces can be stayed in pre-hole, when ejection cylinder 65 goes upward to after top dead center, operating personnel by the pawl utmost point together with overlap with take out and put on the conveyer belt on forcing press side from edger 3 together with piece more than punching, isolating construction by conveyer belt is transported to the pawl utmost point and overlap in different hoppers respectively, after whole stroke finishes, ejection cylinder 65 is got back to starting point.The effect of beating bar 72 and knockout rod 71 on mould bases is to prevent that the remaining piece of punching from staying in the mesopore 51 of punch-die 5, by the dnockout crossbeam on forcing press, piece more than the punching in punch-die 5 is got.

Should be appreciated that specific embodiment described above, only for explaining the present invention, is not intended to limit the present invention.The apparent variation of being extended out by spirit of the present invention or change are still among protection scope of the present invention.
