Abstract
The utility model relates to a side force preventive device in an automobile stamping die for drawing a blank holder glutting, which comprises a screw and a backrest; the backrest is integrated with the base body of a blank holder into a whole body; the backrest is provided with a screw slot in the horizontal direction; and the screw fixes the glutting through the screw slot, so as to prevent the side force of the blank holder glutting. If the side force preventive device is adopted, one or more than one screw hole only needs to be processed on the side wall before the quenching of the glutting, so that procedures are reduced; and the anti-side force of the blank holder glutting is not affected by the quenching and the deformation of the glutting, and the adjustment and the replacement of the blank holder glutting are more convenient.
Description
Technical field
The utility model relates to the anti-side device that the drawing die blank holder is inserted in the automobile diel.
Background technology
Along with the requirement to vehicle safety is more and more higher, the use of high-strength steel sheet also more and more widely.Also more and more higher to the diel requirement of part simultaneously, a large amount of drawing dies must be changed into the steel part piece by former monoblock cast.Because there is the situation that wide variety of materials inwardly flows in binder surface when drawing, so inserting, blank holder also just is subjected to inside strength, do not take the measure of anti-side if blank holder is not inserted, thereby the insert position that will jump of blank holder influence mould use and stamping parts quality so.
At present, all be to take anti-side switch and anti-side pin dual mode before the anti-side measure that blank holder is inserted.All there are weak point in anti-side switch and anti-side pin dual mode.Because blank holder is inserted and all will be carried out Quenching Treatment, quenching 58--62HRC is difficult to carry out the processing of pin-and-hole and keyway later on, and institute is former processing in case side switch groove and anti-side pin-and-hole all quench.Just can assemble owing to need to carry out work such as bedding-in after the problem of quenching distortion, blank holder are inserted and quenched, thus, variation has just taken place in anti-side switch groove and anti-side pin-and-hole position, even take some remedial measures to assemble, but effect is had a greatly reduced quality.And it also is very difficult along with the use of mould, changing, adjust the blank holder insert site if desired.
The utility model content
In order to address the above problem, the utility model discloses a kind of anti-side device that blank holder is inserted that draws, comprise screw, backrest, it is an integral body that backrest and blank holder matrix are connected and fixed, be provided with screw slots on the backrest in the horizontal direction, screw is fixedly inserted by these screw slots and is used to the side force that prevents that blank holder from inserting.
The employing the beneficial effects of the utility model are: only need to process one or several screw hole before quenching and reduce operation thereby insert, and blank holder inserts and is not subjected to insert the influence of quenching distortion at sidewall, the adjustment of blank holder insert site, change also more convenient.
Description of drawings
Fig. 1 adopts the embodiment of anti-side switch for prior art;
Fig. 2 adopts the embodiment of anti-side pin for prior art;
Fig. 3 is the utility model one embodiment.
The specific embodiment
For the easier quilt of the utility model is understood, below we do detailed explanation with the specific embodiment to the utility model in conjunction with the accompanying drawings.
Along with the requirement to vehicle safety is more and more higher, the use of high-strength steel sheet also more and more widely.Also more and more higher to the diel requirement of part simultaneously, a large amount of drawing dies must be changed into the steel part piece by former monoblock cast.Because there is the situation that wide variety of materials inwardly flows in binder surface when drawing, so blank holder is inserted and 2 is also just received inside strength, if not to blank holder 2 measures of taking anti-side of inserting, thereby blank holder 2 positions that will jump of inserting influences the quality of mould use and stamping parts so.It all is to take anti-side switch 4 and anti-side pin 3 dual modes that blank holder is inserted before 2 the anti-side measure.
Consult Fig. 1, prevent the side processing for adopting anti-4 pairs of blank holders of side switch to insert.
Consult Fig. 2, prevent the side processing for adopting anti-3 pairs of blank holders of side pin to insert.
Yet all there are weak point in anti-side switch 4 and anti-side pin 3 dual modes.Because blank holder is inserted and 2 all will be carried out Quenching Treatment, quenching 58--62HRC is difficult to carry out the processing of pin-and-hole and keyway later on, and institute is former processing in case side switch groove and anti-side pin-and-hole all quench.Because the problem of quenching distortion, blank holder is inserted and 2 is needed to carry out work such as bedding-in after quenching and just can assemble, and thus, variation has just taken place for anti-side switch groove and anti-side pin-and-hole position, even take some remedial measures to assemble, but effect is had a greatly reduced quality.And it also is very difficult along with the use of mould, changing, adjust blank holder 2 positions of inserting if desired.
Therefore, we adopt another mode that blank holder is inserted 2 to prevent that side handles.
Consult Fig. 3,, propose to adopt screw 1 to prevent the insert structure of 2 side forces of blank holder at the shortcoming of anti-side switch 4 and anti-side pin 3.At first on inserting 2 rear matrixes, blank holder designs a backrest 5, this backrest is fixedlyed connected as a whole with the blank holder matrix, one or several horizontal screw slots of processing on backrest 5 are installed horizontal screw then, and are utilized this screw to prevent the side force that blank holder is inserted again.
The anti-side device that adopts this structure to insert as blank holder, only needing to process one or several screw hole at sidewall before the quenching of inserting gets final product, do not worry the being inserted influence of quenching distortion, and, blank holder insert when needing to adjust the position or when replacing also convenient.
Claims (1)
1. one kind draws the anti-side device that blank holder is inserted, it is characterized in that, described anti-side device comprises screw, backrest, backrest is located at blank holder and is inserted on the matrix of rear, insert with blank holder and matrix is connected and fixed as a whole, screw slots are set on the backrest in the horizontal direction, and screw is fixedly inserted by these screw slots and is used to the side force that prevents that blank holder from inserting.
