The utility model discloses a side wall drawing die for a passenger car. The side wall drawing die for the passenger car at least comprises a female die, a male die and a lower template, wherein the female die is movably connected with the male die; the male die is movably connected with the lower template; the male die is provided with a jacking device; the jacking device comprises a jacking block and a telescopic device; one end of the jacking block is a working surface; the working surface is movably connected with the female die; and the other end of the jacking block is connected with the lower template through the telescopic device. Due to the adoption of the side wall drawing die for the passenger car, the original shape of a metal plate can be kept when stamping is not required during stamping operation, unnecessary crease marks generated during drawing operation existing in the prior art are avoided, the problem of slip lines is solved fundamentally, the side wall drawing process for the passenger car is optimized, and the attractiveness of a side wall of the passenger car is greatly improved simultaneously.
Description
Technical field
The utility model relates to a kind of car side wall drawing die, relates in particular to the punch of this drawing die.
Background technology
The gusset of car is one-time formed stamping parts; Need specially designed drawing die in the production process; Basically die and punch have been comprised in this mould; Move toward one another about die and the punch after panel beating is put into mould, until tight closure together, panel beating forms being seen profile in the useful application under the extruding of two moulds.In the operating process of the existing technology of drawing; It is existing that slippage appears in the oil filler outward appearance zone of car side wall; " double-edged eyelid " are clearly accomplished behind the enamelling process in application, and as shown in Figure 1, the reason that this stamping defect causes is panel beating 3 is drawn by periphery in punching course at the position of punch 2 corresponding punching press oil fillers influence; Cause panel beating 3 when not having the punching press oil filler, to form and the corresponding folding line 1 of oil filler; Because the different characteristics of situation that the panel beating material has characteristic and each position of extension to extend, cause again after the operation of punching press oil filler this folding line 1 to follow panel beating 3 irregular distortion and displacement, originally the folding line 1 of generation is not on initial position; So the folding line that pilot process produces with regard to slippage to the appearance surfaces of automobile, so skid wire occurred.This skid wire adds that the normal folding line in oil filler shaping back has just formed above-mentioned " double-edged eyelid " phenomenon.This stamping defect obviously has been reduced to the quality and the result of use of car side wall.
The utility model content
The technical problem that the utility model will solve provides a kind of car side wall drawing die, and this mould structure is simple, can eliminate the skid wire that occurs in the car side wall production process.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this car side wall drawing die comprises die, punch and lower bolster at least, and said die and punch flexibly connect; Said punch and lower bolster flexibly connect; Said punch is provided with jacking apparatus, and said jacking apparatus comprises jack-up piece and retractor device, and said jack-up piece one end is a working face; Said working face and die flexibly connect, and the said jack-up piece other end is connected with lower bolster through retractor device.
The utility model makes panel beating in drawing process, obtain bracketing at the position that oil filler is set through the supporting role of jack-up piece, makes panel beating and punch be used for the edge separation of punching press oil filler, thereby avoids producing unnecessary folding line.
Preferred as the utility model flexibly connects through guider between said jack-up piece and the punch.Guider comprises guide plate, and the corresponding guide plate of punch and the guide protrusions that is provided with, and this convexity is provided with smooth spigot surface, and guide plate is installed in the jack-up piece outside, the lateral surface of guide plate directly with the spigot surface flexible connection.This guiding mechanism is simple in structure, and operational efficiency is high.
Preferred as the utility model flexibly connects through stopping means between said jack-up piece and the punch.Stopping means comprises gag lever post and holder, and this gag lever post is positioned at the jack-up piece, and an end diameter is bigger, and the other end passes the jack-up piece and is connected on the holder, and holder is fixedly connected with punch.There has been the position-limiting action of stopping means just can guarantee that the jacking amount of jack-up piece can not exceed design load, thereby can have improved the stamping quality of panel beating.
The utility model adopts technique scheme: this car side wall drawing die can keep its due shape in the time that does not need punching press with panel beating in punching operation; Avoided drawing the unnecessary folding line that produces when operating in the technology in the past; So fundamentally solved the problem of skid wire; Optimize the car side wall drawing work, increased the aesthetics of car side wall simultaneously greatly.

Fig. 2 is the structural representation of a kind of car side wall drawing die of the utility model;
Fig. 3 is the partial enlarged drawing of Fig. 2;
Fig. 4 is the process schematic representation that utilizes behind a kind of car side wall drawing die of the utility model.
The specific embodiment
Like Fig. 2, shown in 3, the car side wall drawing die has comprised die 4, punch 2 and lower bolster 5.Lower bolster 5, punch 2 and die 4 vertically are provided with successively from the bottom up, through the hydraulic telescopic device flexible connection, are fixedly connected through fastening bolt between punch 2 and the lower bolster 5 between die 4 and the punch 2.Be used for the oil filler place on the punching press car side wall at punch 2, be provided with jacking apparatus.This jacking apparatus comprises jack-up piece 6, retractor device, guider and stopping means.Jack-up piece 6 one ends are working face, and the other end is fixed on the lower bolster 5 through retractor device.Flexibly connect through guider between jack-up piece 6 and the punch 2.This guider comprises guide plate 7 and punch 2 corresponding guide plates 7 and the guide protrusions 8 that is provided with, and this convexity is provided with smooth spigot surface 9; Guide plate 7 is installed in jack-up piece 6 outsides, direct and spigot surface 9 flexible connections of guide plate 7 lateral surfaces.Also flexibly connect between jack-up piece 6 and the punch 2 through stopping means.Stopping means comprises gag lever post 10 and holder 11, and this gag lever post 10 is installed in the jack-up piece 6, and an end is screwed with nut, thereby should hold diameter bigger, and the other end passes jack-up piece 6 and is connected on the holder 11, and holder 11 is fixedly connected with punch 2.Holder 11 is positioned at the centre of jack-up piece 6 and retractor device, therefore on holder 11, is provided with through hole, can make retractor device pass holder 11 and be connected with jack-up piece 6.Retractor device is pneumatic retractor device, comprises backing plate 12, cylinder 13 and push rod 14, and push rod 14 1 ends pass holder 11 and are fixed on the jack-up piece 6 through backing plate 12, and this backing plate 12 is connected with jack-up piece 6 through screw, and cylinder 13 is installed on the lower bolster 5 through screw.Jack-up piece 6 just can move up and down through retractor device like this, and its working face can exceed punch 2 surfaces.
During use; Panel beating 3 is placed on jack-up piece 6 rise under raising of retractor device acts in back on the punch 2; Because the gag lever post 10 of stopping means is screwed with the ascending motion that this end of nut has stoped jack-up piece 6; Cause the surface of working face and the punch 2 of jack-up piece 6 to maintain an equal level, as shown in Figure 4, the skid wire that in process technology in the past just can not appear in the initialization phase that panel beating 3 is drawing, exists like this; Panel beating still keeps slick and sly surface at this place, and then makes and behind the punching press oil filler, do not have again skid wire to influence the quality of car side wall.
