Preferably, described patrix also comprises the limited block be fixed in described upper model fixing seat, and described limited block also can limit the displacement of punch cushion block and the first discharging mold insert between described punch cushion block and described first discharging mold insert.
The beneficial effects of the utility model are: described Drawing Die can complete shaping to stamping, shaping and discharge process a station.The utility model structure is simple, ensure that the positioning precision of part and the continuity of punching course, improves dimensional accuracy and the production efficiency of product, decrease production cost, have good practical value.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the original state of Drawing Die of the present utility model.
[detailed description of the invention]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
With reference to figure 1, be the original state of Drawing Die of the present utility model, the counterdie 2 that described Drawing Die 100 comprises patrix 1 and coordinates with described patrix 1: wherein,
Described patrix 1 comprises top base 10, the push pedal 110 of flexible fastening in described top base 1, be positioned at the upper padding plate 20 be fixedly connected with below described top base 10 and with described top base 10, mobilizable the first patrix push rod 21 and the second patrix push rod 22 be plugged in upper padding plate 20, to be positioned at below described upper padding plate 20 and to be fixedly connected with described upper pad 20 plate and there is the upper model fixing seat 30 of receiving space, described patrix 1 also comprises mobilizable punch cushion block 31 be plugged in receiving space, the punch fixed block 32 be connected with described punch cushion block 31, first discharging mold insert 41 spaced with described punch fixed block 32, the the second discharging mold insert 42 be fixedly connected with described first discharging mold insert 41, be fixed on the 3rd discharging mold insert 43 in described second discharging mold insert 42, mobilizable forming terrace die 51 be plugged in described first discharging mold insert 41 and described 3rd discharging mold insert 43.Described first patrix push rod 21 is between described push pedal 110 and described punch cushion block 31, and one end of the first patrix push rod 21 abuts with described push pedal 110, the other end abuts with described punch cushion block 31.One end of described forming terrace die 51 is fixed on described punch fixed block 22, the other end is corresponding with described counterdie 2 is arranged.Described patrix 1 also comprises the limited block 34 be fixed in described upper model fixing seat 30, and described limited block 34 also can limit the displacement of punch cushion block 31 and the first discharging mold insert 41 between described punch cushion block 31 and described first discharging mold insert 41.
Described counterdie 2 comprises bottom base 50, the lower model fixing seat 60 be fixed on described bottom base 50, the die mold insert 61 be fixed in described lower model fixing seat 60, the female die for forming 51 be fixed in described die mold insert 61, to be arranged in above described die mold insert 61 and to be mobilizablely set in die floating block 62 on described female die for forming 51 and to be mobilizablely plugged in described die floating block 62 with die mold insert 61 and can to promote the counterdie push rod 25 that described second discharging mold insert 42 moves, and the top of described female die for forming 52 is corresponding with the bottom of described forming terrace die 51 to be arranged.
Introduce the process of shaping, shaping and discharging below in detail.
Be shaped: during patrix 1 mould 2-in-1 with counterdie, respectively spring force is applied to the second patrix push rod 22 and counterdie push rod 23, stamping strip is placed in the top of female die for forming 52, the down punching press of described patrix 1, the bottom of forming terrace die 51 abuts with stamping strip and continues down punching press, the spring force be subject to due to counterdie push rod 23 is greater than the spring force suffered by the second patrix push rod 22, so the second discharging mold insert 42 is up promoted in matched moulds process, the first discharging mold insert 41 is driven up to move thus, until the first discharging mold insert 41 abuts with limited block 34, namely the upper surface of the first discharging mold insert 41 touches the lower surface of limited block 34, like this, the lower surface of forming terrace die 51 is exposed from the 3rd discharging mold insert 43, push down stamping strip and carry out bending and forming, stamping strip is made to turn up two vertical edges.
Shaping: after stamping strip is shaped, because patrix 1 continues down to move, the lower surface of upper model fixing seat 30 can abut with die floating block 62, go up model fixing seat 30 thus can promote die floating block 62 and down move, thus die floating block 62 is abutted with die mold insert 61, then forming terrace die 51 reaches the extreme lower position of shaping, forming terrace die 51 and counterdie 1 are rigid contact, at this moment matched moulds is continued, start to increase to the decrement of the spring force of push pedal 110 applying, such 3rd discharging mold insert 43 relatively forming terrace die 51 moves downward, 3rd discharging mold insert 43 drops to certain position relatively, touch the vertical both sides of stamping strip bending, to the extruding of two vertical edge trace of bending.When punch cushion block 31 touches upper padding plate 20, at this moment shaping amount reaches maximum.Now, matched moulds process terminates.
Discharging: in die sinking process, due to the effect of patrix 1 spring force, second patrix push rod 22 provides a thrust to the second discharging mold insert 42, promote the second discharging mold insert 42 to move downward, because the 3rd discharging mold insert 43 is fixed in the second discharging mold insert 42, the 3rd discharging mold insert 43 also can move downward thereupon, and the 3rd discharging mold insert 43 promotes stamping strip and moves downward thus, stamping strip is departed from from forming terrace die 51, realizes discharge process.Solve product thus easily to pack tightly on forming terrace die in bending and forming, difficult drop-off during die sinking, but also the problem that may in die sinking process, material strip is out of shape.
Drawing Die of the present utility model can complete shaping to stamping, shaping and discharge process a station.The utility model structure is simple, ensure that the positioning precision of part and the continuity of punching course, improves dimensional accuracy and the production efficiency of product, decrease production cost, have good practical value.
Above-described is only embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite not departing from the utility model creation design; improvement can also be made, but these all belong to protection domain of the present utility model.
