Abstract
The utility model relates to a kind of continuous blanking die of automobile longitudinal girder upper parts, part of the lower die: comprise die shoe (1), and the stamping cavity die cutter (2) that die shoe (1) sets gradually, counterdie edge iron block (3); Part of the upper die: comprise upper bolster (4), and punching press drift, patrix edge iron block, holding pad (5) that upper bolster (4) lower surface sets gradually; Described holding pad (5) is arranged at the middle and lower part of patrix edge iron block and is connected with patrix edge iron block.Prior art is compared, and the utility model has that quality is high, easy to maintenance, low cost and other advantages.
Description
Technical field
The utility model relates to automobile longitudinal girder rear portion shrouding part, especially relates to a kind of continuous blanking die of automobile longitudinal girder upper parts.
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 top is as the important component part of on body of a motor car, and the intensity on longeron top and quality directly affects the quality of Integral automobile Strength Safety, and the production stability on longeron top is most important.At present in a lot of situation traditional moulds punching press once can only punching one and half operation part in process of production, 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 blanking die of the automobile longitudinal girder upper parts 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: a kind of continuous blanking die of automobile longitudinal girder upper parts, 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;
Part of the upper die: comprise upper bolster, and punching press drift, patrix edge iron block, holding pad 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;
Upper bolster is driven by press and presses to die shoe, and material to be processed is compressed by holding pad, and then punching press drift coordinates with stamping cavity die cutter and carries out punching press action, and meanwhile, counterdie edge iron block cooperation patrix edge iron block carries out deburring action, once drops out semi worked pieces.
Described punching press drift is abnormal-shaped punch.
Described punching press drift is in being with square shape jaggy, its barbed portion indentation or arc shape.
Described punching press drift and stamping cavity die cutter composition punching assembly, it is two right that punching assembly is provided with, and be symmetricly set on mould both sides, a punching press forms two symmetries at material to be processed and presses mouth in a state of excitement.
Described counterdie edge iron block and patrix edge iron block are changeable type insert structure.
Described upper bolster is equipped with the end place, angle of die shoe corner the guide pillar that four are connected upper die and lower die.
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 blanking, decrease required jig frequency, the actions such as puncture motion deburring action and flange are carried out simultaneously, one-shot forming, this mould is automatically produce, and eliminates the potential safety hazard of operating personnel.

Fig. 1 is the structural representation of the utility model mould;
Fig. 2 is the stock layout schematic diagram of technique on the utility model mould;
Fig. 3 is the structural representation of the utility model mould upper punch and corresponding punching.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment 1
As shown in Figures 1 to 3, a kind of continuous blanking die of automobile longitudinal girder upper parts, comprises
Part of the lower die: comprise die shoe 1, and the stamping cavity die cutter 2 that die shoe 1 sets gradually, counterdie edge iron block 3;
Part of the upper die: comprise upper bolster 4, and punching press drift 7, patrix edge iron block, holding pad 5 that upper bolster 4 lower surface sets gradually; Described holding pad 5 is arranged at the middle and lower part of patrix edge iron block and is connected with patrix edge iron block;
Described punching press drift 7 is abnormal-shaped punch.Described punching press drift is in being with square shape jaggy, the curved shape of its barbed portion.Described punching press drift 7 and stamping cavity die cutter 2 form punching assembly, and it is two right that punching assembly is provided with, and be symmetricly set on mould both sides, a punching press forms two symmetries at material to be processed and presses mouth 8 in a state of excitement.Then deburring formation shape is carried out identical, the formed product sample that position is staggered, as shown in figures 2-3.This is owing to considering blade portion subregion out-of-shape, conveniently keeping in repair, and blanking is easy, therefore first goes out complicated small gap position in early stage.The edge of a knife of blanking procedure is just more stable so below, because complex region abnormal-shaped punch replaces.Can directly change when going wrong, maintenance, does not affect production.
Described counterdie edge iron block 3 and patrix edge iron block are changeable type insert structure.
Described upper bolster 4 is equipped with the end place, angle of die shoe 1 jiao the guide pillar 6 that four are connected upper die and lower die.
During use, upper bolster 4 is driven by press and presses to die shoe 4, and material to be processed is compressed by holding pad 5, then punching press drift coordinates with stamping cavity die cutter 2 and carries out punching press action, meanwhile, counterdie edge iron block 3 coordinates patrix edge iron block to carry out deburring action, once drops out semi worked pieces.
Embodiment 2
Described punching press drift 7 is abnormal-shaped punch.Described punching press drift is in being with square shape jaggy, its barbed portion indentation.All the other are with embodiment 1.
