Abstract
The utility model belongs to the technical field of stamping of intercoolers of automobiles and particularly relates to a stamping die for a total-aluminum welded intercooler main leaf of an automobile. The stamping die comprises a concave die and a backing plate, wherein the backing plate is arranged on the concave die and fixedly connected with the concave die, and a plurality of holes corresponding to all main leaf holes in the main leaf are formed in the backing plate. All the holes in the backing plate are provided with turnups, and the shapes of the turnups of all the holes in the backing plate are same as those of turnups of the main leaf holes. According to the stamping die for the total-aluminum welded intercooler main leaf of the automobile, the turnups and punched holes of the main leaf are formed in a one-time mode, precision of parts is promoted, and error is reduced.
Description
Technical field
The utility model belongs to automobile charge air cooler stamping technology field, specifically the diel of the full aluminium welded type of a kind of automobile charge air cooler main leaf.
Background technology
The vitals that automobile is charge air cooler with full aluminium welded type charge air cooler main leaf, along with the development of auto manufacturing, the demand of charge air cooler is also in continuous increase.But also have many weak points in the raising that is restricting production efficiency and product quality, existing main leaf mostly is the dull and stereotyped no flange formula main leaf (shown in Fig. 1 a-1b) of hole periphery greatly, during the core body assembling, because the main leaf bore edges does not have flange, can only assemble by hammering method during operation, the angle of collapsing when main leaf can only rely on punching press imports in the main leaf hole cooling tube, and efficiency of assembling and quality all are subjected to great restriction like this.Utmost point individual product is because the needs of use and assembling automatically can only pass through casted die mould die mould (shown in Fig. 3 a-3b), perforating die punching two procedures just can obtain the flange main leaf (shown in Fig. 2 a-2b) in the ideal, the flange main leaf has the bigger fillet along week, makes cooling tube to import more easily in the main leaf hole.Such molding procedure not only wastes time and energy, increases cost, and two procedures, and inevitable error also appears in twice location easily, influences product quality, increases percent defective.
The utility model content
At the problems referred to above, the purpose of this utility model is to provide the diel of the full aluminium welded type of a kind of automobile charge air cooler main leaf.This diel main leaf flange, punching one-step moulding improve part precision, reduce error.
To achieve these goals, the utility model is by the following technical solutions:
The diel of the full aluminium welded type of a kind of automobile charge air cooler main leaf comprises die and backing plate, and wherein backing plate is arranged on the die and with die and fixedlys connected, and described backing plate is provided with a plurality of holes corresponding with each the main leaf hole on the main leaf.
Each hole on the described backing plate is equipped with flange.The flange in each hole on the described backing plate is identical with the flange profile in main leaf hole.Described backing plate is fixedlyed connected with die by hold-down screw.The top edge in each hole on the described backing plate is along being circumferentially with the R angle.
Advantage of the present utility model and beneficial effect are:
1. the utility model makes main leaf flange and punching one-step moulding, and less error improves part precision.
2. the utility model has improved production efficiency, has reduced production cost.

Wherein: 1 is die, and 2 is backing plate, and 3 is hold-down screw, and 4 is conventional main leaf, and 5 is the flange main leaf.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Shown in Fig. 4 a-4c, the utility model comprises die 1 and backing plate 2, wherein backing plate 2 is arranged on the die 1, also fixedlys connected with die 1 by hold-down screw 3, described backing plate 2 is provided with a plurality of holes corresponding with each the main leaf hole on the main leaf, and namely the pitch in the hole on the backing plate 2 and hole count equate with pitch and the hole count in main leaf hole respectively.Each hole on the described backing plate 2 is equipped with flange, and the flange in each hole on the backing plate 2 is identical with the flange profile in main leaf hole.The top edge in the hole on the backing plate 2 is along being circumferentially with the R angle.
The course of work of the present utility model is:
During the utility model punching, the main leaf blank is placed on the backing plate 2, when drift moves downward, contact with blank earlier, because backing plate 2 is with the cutting edge of blank and die 1 from a distance, so can only being in blank elder generation pull and stretch to the cutting edge of die 1, drift carries out punching, form the main leaf of band flange.
