The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing:
As Fig. 1: the utility model comprises cope match-plate pattern 1 and lower bolster 10, and cope match-plate pattern 1 and lower bolster 10 play working portion of die location and fixing effect.Dovetail vertebra 7 is arranged on the cope match-plate pattern 1, is to be convenient to be connected with the equipment slide block by drift; Lower bolster 10 and stationary table.Working portion of die utilizes groove 1a and the 10a on the bolster to be positioned in the template with retainer plate is inserted, adopts screw to fix, and versatility is good, and is easy to adjust.
Former hole drift is installed on cope match-plate pattern side by side and is pressed word drift fixator, press to install on the word drift fixator and press the word drift, correspondence position is installed punching concave die side by side and is pressed the word loose tool on lower bolster.
Employing standard guide pillar 2 guarantees bolster center degree with the precision-fit of guide pin bushing 3.
As Fig. 1, Fig. 3, Fig. 4:
Correspondence position is installed counterdie working portion of die punching concave die side by side and is pressed the word loose tool on lower bolster.
The loose tool relocation mechanism is installed on lower bolster 10, pressure word loose tool 13 is placed on the loose tool relocation mechanism and is positioned at the loose tool groove 10a of lower bolster correspondence, the loose tool relocation mechanism is included in four perpendicular steps hole 10b on the lower bolster 10, on the step of each perpendicular steps hole 10b disk spring 11 is arranged, be placed on four tape spool shoulder push rods 12 in the disk spring 11, press word loose tool 13 to place on four push rods 12, press word loose tool both sides fixing, make the precommpression position of pressing the word loose tool to be positioned at disk spring 11 with pressing plate 16.Screw 14 is connected presses on the word loose tool, utilizes the nut disc to cooperate with forging former hole, realizes forging in the circumferential location of pressing on the word loose tool 13, guarantees the position degree of forging pressure word, uses screw 14 simultaneously, is convenient to press the taking-up of word loose tool 13.The 15th, prefix fixator 17 and the attachment screw of pressing word punch holder 5.
As Fig. 1, Fig. 5, Fig. 6, Fig. 2:
Patrix working portion of die pierce punch is installed on cope match-plate pattern 1 side by side and is pressed word drift fixator, press to install on the word drift fixator and press the word drift.
Pierce punch comprises former hole drift 9 and interstitial hole drift 8, and former hole drift 9 is used for towards the former hole, and interstitial hole drift 8 is used for towards interstitial hole, is fixed on the cope match-plate pattern by drift fixator 22, guarantees the relative position in former hole, and it is convenient to change simultaneously.
Former hole drift 9 and interstitial hole drift 8 are the monolateral gap of 0.5～0.7mm with the gap of groove cutting edge 21a, guarantee that the forging punching can the pull-up burr.
Press the word drift to comprise and press word drift fixator 4, press word punch holder 5, prefix fixator 17, prefix to insert 19; Press to install on the word drift fixator 4 and press word punch holder 5, prefix fixator 17 to be fixed on to press word punch holder 5 lower ends, prefix to insert 19 to be fixed on the prefix fixator 17.The 6th, the attachment screw of pressure word drift fixator 4 and cope match-plate pattern 1.The 15th, prefix fixator 17 and the attachment screw of pressing word punch holder 5.
By pressing word drift fixator 4 and pressing word punch holder 5 to cooperate the locus size of formation to guarantee the position of forging pressure word prefix.Its structure adopts separate form, simplifies the mould manufacturing, can realize seriation and standardization.
Because mould prefix 19 protrudes, relatively other parts are easy to wearing and tearing, with itself and prefix fixator 17 design mix body structures, with the relatively cheap material manufacturing prefix fixator of material, with screw 18 prefix 19 is fixed on the prefix fixator 17, makes its easy accessibility.For adapting to many batches of kind productions in enormous quantities,,, adopt measuring instrument steel material wear-resisting and that hear resistance is strong to make respectively according to part code name, manufacturer's code name, place of production code name and the classification of batch code name with the prefix standardization.The batch code name needs often to change simultaneously, with its design mix body structure, is combined into the head character block of standard with three splits.
Forging after the punching is pressed word on loose tool 13, on loose tool former position screw is set, the former hole is close to screw and realizes circumferentially location.Press in the word process, loose tool 13 floats on four groups of disk springs 11 by push rod 12, utilizes the spring resistance to compression pression that head character block printed words on the drift are pressed into forging.Press on the word loose tool 13 and locate, both made things convenient for Mould Machining, can guarantee that again mould is easy to adjust by screw is set.
Press word loose tool 13 to float on disk spring 11 for convenience, utilize pressing plate 16 to fix it in disk spring 11 precompressed positions, loose tool moves up and down in the groove 10a of lower bolster 10.
This mould is adapted on the press tooth base hot forging being carried out former punching and indentation word, makes simple, easy to adjust.
