Description
Technical field
The utility model relates to automobile longitudinal girder rear portion shrouding part, especially relates to the continuous seepage mould of a kind of automobile longitudinal girder rear portion shrouding part.
Background technology
The Hyundai Motor overwhelming majority has the vehicle frame as car load skeleton, and vehicle frame is the matrix of whole automobile, and its effect is each parts that supporting connects automobile, and bears the various load inside and outside from car.Vehicle frame is made up of longitudinal and cross beam usually, adopts riveted joint or welding that longitudinal and cross beam is connected into firm braced frame.Wherein, automobile longitudinal girder has great impact to body of a motor car collision performance, therefore requires that longeron has good shock resistance and bending resistance.
Automobile longitudinal girder adopts low alloy steel plate to be stamped to form usually, its section configuration is generally U-shaped (section along the width of longeron), in order to strengthen the flexible key position of longeron, general employing section is that the reinforcement of U-shaped superposes and is welded in the U-lag of longeron.Longeron rear portion is provided with rear portion shrouding, and improving constantly of requiring along with the security legislation relevant to car crass, higher requirement be it is also proposed to the intensity of automobile longitudinal girder and rear portion shrouding and anti-bending strength, especially need to ensure that longeron still has enough intensity and anti-bending strength when automobile high-speed collides.
Longeron rear portion shrouding is as the important component part of on body of a motor car, and the intensity of longeron rear portion shrouding and quality directly affects the quality of Integral automobile security, and the production stability of longeron rear portion shrouding is most important.Existing longeron rear portion shrouding completes production by fracture, drawing, edge-cutting and hole-punching, flanging and restriking, separation 5 operations, in a lot of situation, punching press once can only punching one and half operation part in process of production for traditional moulds, and use drawing technology aborning, increase cost of stamping, potential safety hazard is there is in human users's process, and to punching parts because the maloperation of people causes part quality problem.
Summary of the invention
The purpose of this utility model is exactly provide the continuous seepage mould of the automobile longitudinal girder rear portion shrouding part that a kind of quality is high, easy to maintenance, cost is low to overcome defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: the continuous seepage mould of a kind of automobile longitudinal girder rear portion shrouding part, is characterized in that, comprise
Part of the lower die: comprise die shoe, and the stamping cavity die cutter that die shoe sets gradually, counterdie edge iron block, flange lower punch, dressing stick, discharge gate;
Part of the upper die: comprise upper bolster, and punching press punch cutter, patrix edge iron block, flange cutter, holding pad, reforming plunger that upper bolster lower surface sets gradually; Described holding pad is arranged at the middle and lower part of patrix edge iron block and is connected with patrix edge iron block;
Corresponding with part of the lower die through the part of the upper die successively stamping cavity die cutter of part to be processed, punching press punch cutter carry out punching, through counterdie edge iron block and the patrix edge iron block deburring corresponding with it shaping, then flange lower punch is inputted, coordinate with holding pad while pushing down forming part material by flange cutter and clamp the downward flange of forming part material, controlling homogenize material ground to walk from R angular flux, discharging from discharge gate finally by being separated after dressing stick and reforming plunger shaping.
Described flange lower punch is provided with the projection matched with part to be processed, described holding pad is positioned at above flange lower punch, and forming part is clamped together with flange cutter, and holding pad and flange cutter edge form displacement difference, this displacement difference is more than or equal to the length of parts flanged-edge.
Described holding pad connects nitrogen cylinder, and nitrogen cylinder drives holding pad clamping or unclamps part.
Described die shoe is provided with the end place, angle of upper bolster four guide pillars being connected upper die and lower die.
Described counterdie edge iron block and patrix edge iron block are changeable type insert structure.
Compared with prior art, the utility model has the following advantages:
(1) long service life: all deburrings all use insert form.Extend the service life of mould self, reduce the infringement to production equipment and consume.
(2) easy to maintenance: to use insert structure, when keeping in repair need not again by whole mold hoisting to maintenance sites, take a large amount of places, the insert needed repairing need be pulled down and can be keeped in repair;
(3) ram efficiency high cost of stamping is low: according to grading mode continuous seepage, decrease required jig frequency, puncture motion and deburring action are carried out simultaneously, one-shot forming, and this mould is automatically produce, and eliminates the potential safety hazard of operating personnel.
(4) process modification of mould, traditional processing technology selects drawing to produce, pass through skill upgrading now, data analysis, structure shows us after improving and adopts full working procedure level progressive die to produce, directly pass through punching, deburring, shaping, flange, separation of produced with coiled strip feeding, changed into being shaped by drawing and produce, stock utilization improves.
(5) full working procedure level progressive die is adopted to produce, directly pass through punching, deburring, shaping, flange, separation of produced with coiled strip feeding, changed into being shaped by drawing and produce, on overturning process, increase holding pad, flange cutter coordinates Clamp blocks shape to face down to turn over time while pushing down material with holding pad, so can control walking from R angular flux of homogenize material, make R angle smooth, the defect that when overcoming flange in prior art, R angle is wrinkling.
