Description

The simple stretch mould

Technical field

The utility model relates to a kind of simple stretch mould.

Background technology

In the new-product development process, often run into the stamping parts that has drawing and forming, make and will do the shaping mould tool, so want above fabrication cycle of a week at least, it is also very difficult that not only cost height, and ready-made mould will be changed design.

Summary of the invention

The utility model purpose is: a kind of fabrication cycle weak point is provided, makes simple, lower-cost simple stretch mould.

The technical solution of the utility model is: a kind of simple stretch mould, it comprises punch, punch location-plate and die location-plate, wherein have opening consistent with the punch profile and that can supply punch to pass through on the punch location-plate, and have concave die cavity on the die location-plate with the punch form fit; And the punch location-plate is provided with some relative pin joint holes with the die location-plate.

Being produced as follows of punch described in the utility model, punch location-plate and die location-plate: at first the degree of depth that stretches according to part is selected the general steel plate of respective thickness for use, cuts out the profile of punch, opening on the punch location-plate and the concave die cavity on the die location-plate with laser cutting then; At last on punch location-plate and die location-plate, get some relative pin joint holes, be used for the cross-under alignment pin and lead and locate.Certainly the position in pin joint hole need decide according to the concrete shape of part, mainly is to guarantee that in the pin joint hole part can be fixed behind the cross-under alignment pin, and is mobile.And the utility model is assembled in advance alignment pin on the die location-plate usually, treat that part is placed on the die location-plate and the pin that is positioned fixes after, again the punch location-plate is closed, make corresponding one by one being socketed on the following alignment pin in pin joint hole on it.

The utility model is at first got two die holders ready when concrete the use: upper bolster and die shoe, and they all can select flat steel plate (gauge of steel plate gets final product greater than the pull and stretch part) for use; Then part is placed between punch location-plate of the present utility model and the die location-plate, close punch location-plate and die location-plate because both connect by alignment pin, therefore can effectively fix the location to part.At last the utility model that accompanies part is placed between upper bolster and the die shoe, and guarantee that punch is positioned at the opening on the punch location-plate, with hydraulic press or bender depressing the opening of punch from the punch location-plate, in the concave die cavity on being pressed into the die location-plate, also be that the drawing and forming of part was all right after mould was pressed onto the position.

The utility model simple stretch mould can further comprise a tile height adjustable plate, and the profile of this DOCK LEVELER is consistent with concave die cavity and be positioned at this concave die cavity.The effect of described DOCK LEVELER is promptly in the pressing mold process, and punch enters the degree of depth in the concave die cavity when reducing mould and being pressed onto, and then controls the size of final part, mainly is to be used for obtaining than subscribing the little part of size.

The utility model advantage is:

1. the Mold Making of the utility model simple stretch is simple, fabrication cycle is short, especially it comprises that cutting and alignment pin are assemblied in interior entire making process as long as just can finish less than one hour, compare common mould at present, cost is low, instant effect, it is also very convenient to change design, suitable for making sample or small lot batch manufacture can also be offered reference for making the mould of producing in batches, and practicality is higher.

The specific embodiment

Embodiment: as shown in Figure 1, a kind of specific embodiment for the utility model simple stretch mould, it comprises punch 1, punch location-plate 2, die location-plate 3 and DOCK LEVELER 4, wherein have opening 21 consistent with punch 1 profile and that can supply punch 1 to pass through on the punch location-plate 2, and have concave die cavity 31 on the die location-plate 3 with punch 1 form fit; And be equipped with four pin joint holes 22 on four angles of punch location-plate 2, and also be equipped with four pin joint holes 32 on the die location-plate 3, these four pin joint holes 32 are relative one by one with 22 positions, pin joint hole on the punch location-plate 2.

Below in conjunction with Fig. 2-Fig. 6 the concrete occupation mode of present embodiment is described:

Present embodiment is at first got two die holders ready in use: upper bolster 5 and die shoe 6, and they all select flat steel plate (gauge of steel plate gets final product greater than the pull and stretch part) for use; While assembled in advance alignment pin 7 on die location-plate 3, then part 8 before the processing as shown in Figure 3 is placed on the die location-plate 3, part 8 fixes location (as shown in Figure 4) before making 7 pairs of processing of alignment pin, the punch location-plate 2 that closes again makes corresponding one by one being socketed on the following alignment pin 7 in pin joint hole 22 on it.At last the present embodiment that accompanies the preceding part 8 of processing is placed between upper bolster 5 and the die shoe 6, and guarantee that punch 1 is positioned at the opening 21 on the punch location-plate 2, with hydraulic press or bender depressing the opening 21 of punch 1 from punch location-plate 2, in the concave die cavity 31 on being pressed into die location-plate 3, also be that the drawing and forming of part was all right after mould was pressed onto the position.Processing back part 9 is as Fig. 5, shown in Figure 6.

Again in conjunction with shown in Figure 2, the profile of the DOCK LEVELER 4 in the present embodiment and concave die cavity 31 are consistent and be positioned at this concave die cavity 31, the effect of this DOCK LEVELER 4 is promptly in the pressing mold process, punch 1 enters the degree of depth in the concave die cavity 31 when reducing mould and being pressed onto, and then control the size of final part, mainly be to be used for obtaining than subscribing the little part of size.

Certainly the version of punch, the opening on the punch location-plate and the concave die cavity on the die location-plate in the present embodiment is as shown in Figure 1 just made specially at processing this part as shown in Fig. 5, Fig. 6, and they can not be used for limiting the protection domain of the utility model simple stretch mould.
