Abstract
The invention discloses a local reversing hole flanging device which comprises a permanent seat, a driving block and a hole flanging male die, and the permanent seat is provided with an installation hole connected with a die holder. The local reversing hole flanging device is characterized in that the left part of the middle of a reverse acting lever is connected between two vertical blocks on the permanent seat in a matching way by a rotating shaft; an installation hole connected with an upper die base is arranged at the upper part of the driving block; the front side and the rear side of a convex block on the hole flanging male die are respectively provided with a limiting post, and two spiral springs are respectively sheathed on the two limiting posts. The permanent seat is connected on the upper die holder and the lower die holder of a hole flanging die respectively, and when the hole flanging die works, the driving block contacts with the reverse acting lever, so as to push the hole flanging male die to move upwards to complete local reverse hole flanging, thereby solving the problem that the hole flanging directions of parts are opposite, ensuring the quality of parts, and reducing the production cost.
Description
Technical field
The present invention relates to automobile Stamping Die Technology field, be specifically related to the reverse hole flanging device in a kind of part.
Background technology
Common plunging die generally is made up of punch, die, upper bolster, die shoe, on the die holder, does not have local reverse hole flanging device about punch, die are installed in respectively.But at the member that has, in the hole flanging operation like the glove plate, the hole flanging direction that most hole occurs is consistent, have only the hole hole flanging situation in the opposite direction of only a few, and conventional hole flanging mould does not have local reverse hole flanging device.If adopt the method that increases operation, manufacturing expense increased greatly, and influence the accuracy of manufacture.Therefore, common plunging die needs local reverse hole flanging device use supporting with it.
Summary of the invention
The purpose of this invention is to provide a kind of local reverse hole flanging device simple in structure, with low cost, solve the indivedual hole flangings of part problem in the opposite direction,, reduce manufacturing cost with the stability that rises part status and the quality of part.
Technical scheme of the present invention is following:
The reverse hole flanging device in a kind of part of the present invention; Comprise holder; Be provided with the installing hole that is connected with die holder at this holder, it is characterized in that: the position that reaction lever middle part keeps left, erect between the pieces for two that are connected on said holder through a rotating shaft; Also comprise a drive block, the top of this drive block is provided with the installing hole that is connected with upper bolster; Also comprise a hole flanging punch, the projection front and rear side above the hole flanging punch that is somebody's turn to do is respectively equipped with a limited post, and two helical springs are enclosed within respectively on two limited posts.
The reverse hole flanging device in described a kind of part, its said holder are installed in through screw on the die shoe of hole flanging mould, and said drive block is located by connecting on through screw on the upper bolster of hole flanging mould, and said hole flanging punch is embedded in the upper bolster of hole flanging mould; The lower end of said drive block contacts with the left part of said reaction lever, and the lower end of hole flanging punch contacts with the right part of said reaction lever.
Beneficial effect of the present invention: the reservation branch is installed on the upper bolster, die shoe of hole flanging mould; When the hole flanging mold work, drive block contact reaction lever, thus it is up to promote the hole flanging punch; Accomplish local reverse hole flanging; Thereby solved part hole flanging problem in the opposite direction, both guaranteed part quality, reduced manufacturing cost again.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that the present invention is installed in the sketch map (closure state) on the hole flanging mould.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
Referring to Fig. 1, the reverse hole flanging device in a kind of part of the present invention, comprise holder 1, be provided with the installing hole that is connected with die shoe 10 at this holder; The position that one reaction lever, 7 middle parts keep left is connected on said holder 1 two through a rotating shaft 2 and erects between the pieces; Erect piece at two and also be respectively equipped with pad 8 and screw 9;
Also comprise a drive block 3, the top of this drive block is provided with the installing hole that is connected with upper bolster 11;
Also comprise a hole flanging punch 4, the projection front and rear side above the hole flanging punch that is somebody's turn to do is respectively equipped with a limited post 5, two helical springs 6 and is enclosed within respectively on two limited posts.
Referring to Fig. 2, said holder 1 is installed in through screw on the die shoe 10 of hole flanging mould, and said drive block 3 is located by connecting on through screw on the upper bolster 11 of hole flanging mould, and said hole flanging punch 4 is embedded in the upper bolster 11 of hole flanging mould; The lower end of said drive block 3 contacts with the left part of said reaction lever 7, and the lower end of hole flanging punch 4 contacts with the right part of said reaction lever 7.When mold work, drive block contact reaction lever, thus it is up to promote the hole flanging punch, accomplishes local reverse hole flanging.
The reverse hole flanging device in common this part is applied under only a few hole in the vehicle body class part 12 and the hole flanging of mostly the counting holes situation in the opposite direction.When the hole flanging mold work, drive block 3 is exercised reaction lever 7 down with patrix makes the hole flanging punch 4 that contacts with reaction lever 7 other ends up around axle 2 rotations, thereby reaches the purpose of local reverse hole flanging.
