Abstract

The utility model relates to a vehicle side body drawing die capable of preventing yawing force from producing. The vehicle side body drawing die capable of preventing yawing force from producing comprises an upper die and a lower die, a blank pressing ring is arranged in the lower die, a cushion block is arranged below the blank pressing ring, and a protruding die is arranged in the blank pressing ring; six yawing force preventing guide plates are arranged on the edges of the upper die, and six yawing force preventing guide sliding surfaces which are correspondingly matched with the six yawing force preventing guide plates are arranged on the blank pressing ring. The vehicle side body drawing die capable of preventing yawing force from producing has the advantages of being capable of preventing from producing yawing force as drawing a vehicle side body, enabling guiding to be stable, thereby improving drawing quality of the vehicle side body.

Description

A kind of vehicle side drawing die that can prevent that side force produces
Technical field
The utility model relates to automobile component stamping die, is specifically related to a kind of vehicle side drawing die that can prevent that side force produces.
Background technology
Drawing is straight woollen or process part processing to be become a kind of stamping procedure of curved surface shaped, and curved surface mainly relies on and is positioned at extending to form of punch base material.At present, when the large-scale body outer skins such as vehicle side are drawn, because its part profile is comparatively complicated, and exist larger drawing depth poor, just make and easily produce side force when drawing on mould, and then make the part guide-localization unstable, thus when making the gusset moulding, cracking appears easily, the problem such as wrinkling, distortion, and affect parts and draw quality.Therefore, need to the drawing die of existing vehicle side be improved.
Summary of the invention
The purpose of this utility model is to provide a kind of vehicle side drawing die that can prevent that side force produces, and it can prevent from producing side force when drawing vehicle side, makes guiding stable, thereby improves the quality of drawing of vehicle side.
A kind of vehicle side drawing die that can prevent that side force produces described in the utility model, comprise upper die and lower die, be provided with blank holder in counterdie, be provided with cushion block below blank holder, be provided with punch in blank holder, it is characterized in that: be provided with six anti-side force guide plates on the edge of described patrix, be provided with on blank holder and described six anti-side force guide plates six anti-side force slide guide faces of corresponding matching one by one.
Be respectively equipped with the patrix guide plate on two minor faces of described patrix, be respectively equipped with lower die guiding sliding surface with two patrix guide plate corresponding matching at two minor faces of counterdie.
Be provided with a plurality of blank holder slide guide faces on the inwall of described counterdie, be provided with on the outer wall of blank holder and described a plurality of blank holder slide guide faces blank holder guide plate of corresponding matching one by one.
Be provided with a plurality of punch slide guide faces on the inwall of described blank holder, be provided with on the outer wall of described punch and described a plurality of punch slide guide faces punch guide plate of corresponding matching one by one.
Be provided with two eccentric swages in described punch, be provided with a plurality of eccentric swage slide guide faces on the inwall of the eccentric swage installation place of punch, be provided with on the outer wall of eccentric swage and described a plurality of eccentric swage slide guide faces eccentric swage guide plate of corresponding matching one by one.
the utlity model has following advantage: because anti-side force guide plate is arranged on patrix, and the anti-side force slide guide face that is mated is mounted on blank holder, when patrix presses down, be slidably matched between anti-side force slide guide face on anti-side force guide plate on patrix and blank holder, along with patrix is descending and to drive blank holder descending, effect due to anti-side force structure, controlled that patrix and blank holder are subject to reaction force in forming process and the side force that forms, and then the position stability of control part in mould, thereby solve the cracking that gusset is shaped and may occurs, wrinkling, the quality problems such as distortion, improve automobile gusset draw quality.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of vehicle side drawing die that can prevent that side force produces, comprise patrix 1, counterdie 2, be provided with blank holder 3 in counterdie, be provided with cushion block 6 below blank holder, be provided with punch 4 in blank holder, be provided with six anti-side force guide plates 11 on the edge of described patrix, be provided with on blank holder 3 and described six anti-side force guide plates six anti-side force slide guide faces 31 of corresponding matching one by one.
As shown in Figure 2 and Figure 3, be respectively equipped with patrix guide plate 12 on two minor faces of described patrix 1, be respectively equipped with lower die guiding sliding surface 21 with two patrix guide plate corresponding matching at two minor faces of counterdie 2.
As shown in Figure 3, Figure 4, be provided with a plurality of blank holder slide guide faces 22 on the inwall of described counterdie 2, be provided with on the outer wall of blank holder 3 and described a plurality of blank holder slide guide faces blank holder guide plate 32 of corresponding matching one by one.
As Fig. 4, shown in Figure 5, be provided with a plurality of punch slide guide faces 33 on the inwall of described blank holder 3, be provided with on the outer wall of described punch 4 and described a plurality of punch slide guide faces punch guide plate 43 of corresponding matching one by one.
As Fig. 5, shown in Figure 6, be provided with two eccentric swages 5 in described punch 4, be provided with a plurality of eccentric swage slide guide faces 42 on the inwall of the eccentric swage installation place of punch, be provided with on the outer wall of eccentric swage 5 and described a plurality of eccentric swage slide guide faces eccentric swage guide plate 52 of corresponding matching one by one.
Mould is when work, and push rod first will be located at cushion block 6 jack-up below blank holder, and then make the certain height of blank holder 3 jack-up, and then patrix 1 is descending, and at first patrix guide plate 12 leads with lower die guiding sliding surface 21, and afterwards, patrix 1 continues descending.
As shown in Figure 7, descending with after blank holder 3 contacts when patrix 1, anti-side force guide plate 11 contacts guiding with anti-side force slide guide face 31, completes drawing operation.By the anti-side force mechanism between patrix and blank holder, eliminate the side force that mould produces in forming process, control the location of side wall parts in mould, make guiding more stable, thereby solve the gusset quality problems such as the cracking that may occur, wrinkling, distortion that are shaped.
