The tapping mode mechanism of a kind of forming terrace die and grading blanking die
Technical field
This utility model belongs to progressive die blanking die, is specifically related to the tapping mode mechanism of a kind of forming terrace die and grading blanking die.
Background technology
In recent years, high-accuracy progressive die blanking die has been widely used in various industry.Usually, the blanking die in current every profession and trade is essentially all single step operation.Therefore to adapt to a kind of product multiple formed features of same station or the demand of multiple similar products one set of die, generally discrepant formed features is designed to station intermittent work state, convenient especially for deep molding character.As it is shown in figure 1, common interval builder, it is mainly made up of upper bolster 1 ', forming terrace die 2 ', upper die plate 3 ', punch retainer 4 ', air cylinder fixed plate 5 ', cylinder 6 ', slide plate 7 '.Described forming terrace die 2 ' is placed in punch retainer 4 ' and upper die plate 3 ', the cylinder body of described cylinder 6 ' is fixed in air cylinder fixed plate 5 ', described air cylinder fixed plate 5 ' is fixed on upper bolster 1 ' sidewall, described forming terrace die 2 ' slips upper at slide plate 7 ' and is connected with cylinder 6 ' piston rod, described slide plate 7 ' slips with upper die plate 3 ' inside groove, the requirement of easy slide is needed to be affected by sliding inclined-plane, sliding inclined-plane needs to process with smaller angle, run into Deep forming punch 2 ' when needing tapping mode to step down to subsequent work stations, slide plate 7 ' height have to be thickeied and increase sliding region, mold thickness is caused to increase, structure is too fat to move, high expensive.
Utility model content
The purpose of this utility model is the defect for prior art; the tapping mode mechanism of a kind of forming terrace die and grading blanking die are provided; so that on the basis of not changing common air-cylinder type tapping mode mechanism height size, forming terrace die is made to obtain deeper forming dimension.
The technical scheme realizing the employing of this utility model purpose is as follows:
The tapping mode mechanism of the forming terrace die that this utility model provides, including forming terrace die with drive the controlling organization that described forming terrace die moves up and down, described forming terrace die includes punch body, the First terrace with differing heights being located at described punch body top and second step face and sidepiece with described First terrace and second step face connects respectively the first inclined-plane and the second inclined-plane;Described controlling organization includes the slide plate coordinated with described forming terrace die and the driving means being connected with described slide plate, and described slide plate includes the 3rd inclined-plane and the 4th inclined-plane being respectively cooperating with the first inclined-plane on described forming terrace die and the second inclined-plane and front and back arranging.
The grading blanking die that this utility model provides, including upper bolster, it is sequentially arranged at the upper die plate below described upper bolster and punch retainer, it is provided with in described upper die plate and punch retainer and is driven, by controlling organization, the forming terrace die moved up and down, described controlling organization includes the slide plate coordinated with described forming terrace die and is located at described upper bolster and the driving means being connected with described slide plate, described forming terrace die includes punch body, it is located at the First terrace with differing heights on described punch body top and second step face and sidepiece with described First terrace and second step face connects respectively the first inclined-plane and the second inclined-plane, described slide plate includes the 3rd inclined-plane and the 4th inclined-plane being respectively cooperating with the first inclined-plane on described forming terrace die and the second inclined-plane and front and back arranging.
Beneficial effect
In the existing mold of moulding process to(for) deep molding character be all the structure of punch do longer, so make the punch rigidity when molding can not be guaranteed, die size is relatively big, and molding character is the most undesirable.And this utility model utilizes cylinder indirectly to control upwardly shaped punch duty, meet a kind of product multiple formed features of same station or the demand of multiple similar products one set of die, make Deep forming punch can change height in a big way by utilizing multistage inclined-plane to slide, and ensure that tapping mode mechanism height is constant, thus reduce mold height, save manufacturing cost, can be widely used in all kinds of multiple site punching progressive die.
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings.

Detailed description of the invention
nullSuch as Fig. 2、Shown in Fig. 6 to Fig. 8,The grading blanking die that this utility model provides,Including upper bolster 1、It is sequentially arranged at the upper die plate 3 below described upper bolster 1 and punch retainer 4,The tapping mode mechanism of forming terrace die it is provided with in described upper die plate 3 and punch retainer 4,This tapping mode mechanism includes forming terrace die 2 and the controlling organization driving described forming terrace die 2 to move up and down in upper die plate 3 and punch retainer 4,Described controlling organization includes the slide plate 7 coordinated with described forming terrace die 2 and the driving means being connected with described slide plate 7,Described forming terrace die includes punch body 203、It is located at the First terrace 201 with differing heights on described punch body 203 top and second step face 202 and sidepiece with described First terrace 201 and second step face 202 connects respectively the first inclined-plane c and the second inclined-plane d,Described slide plate 7 includes the 3rd inclined-plane a and the 4th inclined-plane b being respectively cooperating with the first inclined-plane c on described forming terrace die 2 and the second inclined-plane d and front and back arranging;Described driving means uses cylinder 6, and the cylinder body of cylinder 6 is screwed in air cylinder fixed plate 5, and air cylinder fixed plate 5 is screwed on upper bolster 1 sidewall, and slide plate 7 is connected with the piston rod of cylinder 6, and slide block 7 slips with upper die plate 3 inside groove.
Operation principle
When needing control forming terrace die 2 to enter duty, control cylinder 6 ventilation and drive slide plate 7 forward slip, the first relatively low inclined-plane c(on the 3rd inclined-plane a contact forming terrace die 2 before slide plate 7 is made to see Fig. 3), forming terrace die 2 is forced to move downward a segment distance, the second inclined-plane d higher on forming terrace die 2 declines therewith, contact to the second higher with on forming terrace die 2 for the 4th inclined-plane b inclined-plane d below on it along with slide plate 7 continues forward slip, forming terrace die 2 is again forced to move downward (seeing Fig. 4), the bottom 701 of slide plate 7 contacts with the second step face 202 of forming terrace die 2 and makes forming terrace die 2 spacing, move downward through twice and can realize the degree of depth that forming terrace die 2 arrival shaping needs.When needs control forming terrace die 2 enters off position, control cylinder 6 ventilation and drive slide plate 7 to slide backward, vacate the space stepped down to forming terrace die 2 so that forming terrace die 2 is stopped rollback by plate, is not operated.
