Description
Technical field
The present invention relates to a kind of simple stretch forming method of parts.
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 present invention seeks to: provide a kind of process velocity fast, cost is low, the simple stretch forming method of parts of instant effect.
Technical scheme of the present invention is: a kind of simple stretch forming method of parts, it comprises the steps:
1) makes the simple stretch mould, this simple stretch mould 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;
2) be ready to two die holders: upper bolster and die shoe, part to be processed is placed between punch location-plate and the die location-plate, treat processing parts by alignment pin and fix the location; Then the simple stretch mould that accompanies part to be processed 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.
Being produced as follows of related simple stretch mould in the inventive method: 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 to be processed, mainly is to guarantee that in the pin joint hole part to be processed can be fixed behind the cross-under alignment pin, and is mobile.And assembled in advance alignment pin on the die location-plate usually in the inventive method, wait for that processing parts 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.
Upper bolster that relates in the inventive method and die shoe, they all can select flat steel plate for use, and the gauge of steel plate gets final product greater than the pull and stretch part.
The step 2 of the inventive method) be the pressing mold process, hydraulic press or bender in the concave die cavity on being pressed into the die location-plate, also are that the drawing and forming of part was all right after mould was pressed onto the position depressing the opening of punch from the punch location-plate.
The simple stretch mould that relates in the inventive method 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.
Advantage of the present invention is:
1. simple stretch forming method of parts of the present invention is simple and efficient, process velocity is fast, it comprises that the whole process of the making of simple stretch mould and pressing mold is as long as just can finish less than one hour, cost is low, instant effect, it is also very convenient to change design, and suitable for making sample or small lot batch manufacture can also be offered reference for making the mould of producing in batches.
Description of drawings
Below in conjunction with drawings and Examples the inventive method is further described:

The specific embodiment
Embodiment: simple stretch forming method of parts of the present invention at first needs to make simple stretch mould as shown in Figure 1, this simple stretch mould 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.
In conjunction with Fig. 2-shown in Figure 6, the inventive method further adopts above-mentioned simple stretch mould to carry out the processing of part:
Get two die holders ready: upper bolster 5 and die shoe 6, 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 as shown in Figure 3 part to be processed 8 is placed on the die location-plate 3, make alignment pin 7 treat processing parts 8 and fix location (as shown in Figure 4), 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 simple stretch mould that accompanies part 8 to be processed 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 that relates in the simple stretch mould 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 above-mentioned only is a kind of specific embodiment of the inventive method; the opening on the punch that wherein relates to, the punch location-plate and the version of the concave die cavity on the die location-plate are 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 simple stretch forming method of parts of the present invention.
