Abstract

The utility model provides a drawing mould with hole flanging function used for positioning a following mould. The drawing mould with hole flanging function used for positioning the following mould comprises a lower die base (3) and a terrace die (4). The lower die base (3) is provided with two hole flanging punches (5), wherein the two hole flanging punches (5) are respectively arranged on the side of the terrace die (4) and the hole flanging punches (5) are arranged in the waste area of a blank. By adopting the drawing and hole flanging structure, the drawing mould with hole flanging function used for positioning the following mould flanges two semi-circle holes in the waste area, thereby providing a simple and reliable positioning method for the element positioning of the following trimming and piercing die and increasing the percent of pass of products. And the hole flanging is removed in the trimming and punching process in the waste area, thereby not affecting the function and shape of products.

Description

A kind of have the hole flanging function for the drawing die of postorder mould location

Technical field

The utility model relates to a kind of drawing die.

Background technology

In automobile panel some part profile simple (such as: jack guiding left/right stiffener), drawing depth is shallow.The follow-up trimming die part of this type of part location is unreliable, present conventional way is that Design Orientation device+profile is located all around, adopt Manual plate shearer to cut owing to draw the blank major part, so the billet size of cutting all can there are differences at every turn, add some technical parameters in the mould use procedure also change (such as lathe pressure, mold surface finish etc.) therefore drawn at every turn later around billet size be vicissitudinous, as seen the location can't accurately be located around adopting locator, greatly reduces like this qualification rate and the Product Precision of product.

The utility model content

Technical problem to be solved in the utility model provides a kind of waste material zone at blank and rushes in the product drawing process and turn over two smaller part circular holes and be used for the follow-up drawing die that the hole flanging function is used for postorder mould location that has that stamping die carries out the blank location of repairing.

In order to solve the problems of the technologies described above, the hole flanging function that has that the utility model provides is used for the drawing die that the postorder mould is located, comprise die shoe and punch, be provided with the hole flanging punch of two both sides that are distributed in respectively described punch 4 and waste material zone that described hole flanging punch is in blank at described die shoe.

Adopt the drawing die that the hole flanging function is used for postorder mould location that has of technique scheme, simply counting type according to some part profile in the automobile panel can learn, this product structure is more smooth, overall fluctuation ratio is milder, in order to prevent that the blank location is unstable in repairing punch die, so when Product Process designs, each side increased a hole flanging at the blank garbage area, because this hole flanging is at garbage area, and distant from product, therefore can not affect the punch forming of product.In drawing die, add hole flanging, the plate location that is used for the postorder Trimming Die, namely in drawing die, two hole flanging punchs of waste material zone design at blank, in the product drawing process, utilize hole flanging punch to turn over two smaller part circular holes, because hole flanging punch is fixed, so the hole flanging position is changeless, utilize these two hole flangings to carry out the blank location as the follow-up stamping die of repairing, realize that product in the accurate location of punching course, improves the part qualification rate, it is shallow to have solved drawing depth, profile rises and falls mild, and follow-up trimming die is located insecure orientation problem.

Advantage of the present utility model and good effect:

Employing is drawn the band hole flanging structure and is turned over two semicircle orifices in the waste material zone, and locating for the part of follow-up trimming-punching die provides a simple and reliable localization method, has improved product percent of pass.And hole flanging can repair in waste material zone rush in the order cut, so do not affect product function and shape.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 2, be provided with the hole flanging punch 5 of two both sides that are distributed in respectively punch 4 and waste material zone that hole flanging punch 5 is in blank 6 at die shoe 3.

Referring to Fig. 1, the utility model will be processed jack guiding left/right stiffener, count type according to product and can learn that this product structure is more smooth, overall fluctuation ratio is milder, in order to prevent that blank 6 location are unstable in repairing punch die, so Product Process when design, each side increased a hole flanging 7 at the garbage area of blank 6, because this hole flanging 7 is at garbage area, and distant from product, therefore can not affect the punch forming of product.

Such as Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, two hole flanging punchs 5 are installed on the die shoe 3, are distributed in the both sides of punch 4 and waste material that hole flanging punch 5 is in blank zone.Upper bolster 1 is descending by the guide plate guiding with the lathe top shoe, has guaranteed the mould kinematic accuracy; Upper bolster 1 continues descending until contact fully with blank holder 2, and with blank 6 compactings; Upper bolster 1 and the blank holder 2 simultaneously descending beginning drawing process that contacts with punch 4 profiles begin to contact hole flanging with plate 6 at hole flanging punch 5 when drawing bottom dead centre 5MM and begin, and mould continues to come downwards to bottom dead centre and draws with hole flanging 7 and finish simultaneously.

Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and shown in Figure 8, the utility model adds the hole flanging function in drawing die, be used for the plate location of postorder Trimming Die, and it is shallow to have solved drawing depth, profile rises and falls mild, and follow-up trimming die is located insecure orientation problem.Namely in drawing die, two hole flanging punchs 5 of waste material zone design at blank, in the product drawing process, utilize hole flanging punch 5 to turn over two smaller part circular hole-hole flangings 7, because hole flanging punch 5 is fixed, so hole flanging 7 positions are changeless, utilize these two hole flangings 7 to carry out the blank location as the follow-up stamping die of repairing, realize that product in the accurate location of punching course, improves the part qualification rate.

Positioning principle as shown in Figure 9 and Figure 10, by aligning the location at the hole flanging 7 of repairing stamping die 9 and arrange locator 8 and blank 6, can be good at guaranteeing the drawing operation part in the follow-up accurately location of repairing in the stamping die, for the final mass of product provides one well to guarantee.
