Description
Technical field
The present invention relates to the cold punching technology field, especially relate to a kind of rotary primary and secondary cam die, be applicable to exist negative angle zone workpiece cold stamping shaped.
Background technology
The moulding of product side exists the negative angle zone to adopt traditional board-like cam die of fixed cap cold stamping shaped, has interference point between product and the mould when product takes out, and is not easy to product and takes out.
Such as vehicle side-wall outer-plate, as depicted in figs. 1 and 2, there are negative angle in A post and the front windshield lap-joint of this vehicle side-wall outer-plate, along with people's improving constantly car outward appearance and security, so that product-forming requires obstacle angle β more and more less, A post outward appearance profile width is more and more less, causes the interior step draft angle of door opening more and more to come little, adopt traditional board-like cam die of fixed cap, the interference problem when being difficult to solve pickup between product and the mould.
Adopt traditional board-like cam die of fixed cap to return pickup and mainly contain dual mode: be as shown in Figure 3 and Figure 4 a kind of, the mould back off procedure, the whole die plate insert 3 of linear pattern side and linear pattern cover plate 2 take out interference point along F to moving until it avoids product, and product 1 takes out smoothly; Another kind as shown in Figure 5 and Figure 6, the mould back off procedure, the whole die plate insert 6 of circular arc type side and circular arc type cover plate 5 rotate around the shaft, take out interference point until it avoids product, product takes out smoothly.In the above-mentioned dual mode, cover plate all is fixed, and when vehicle body obstacle angle β was smaller, the taking-up of product interfered critical point 4 the closer to the door opening side, A post outward appearance profile width is smaller in addition, when the deep draft angle of step is smaller in the door opening simultaneously, affect the intensity of cover plate, What is more, and cut-off rule has exceeded product, cause adopting traditional fixed cover plate Wedge mechanism, can't realize that product takes out, restrict the development of product, have a strong impact on the lifting of vehicle body security performance.
Summary of the invention
Technical problem to be solved by this invention provides a kind of rotary primary and secondary cam die, its objective is that when there was the negative angle zone in the product moulding, product was convenient to take out.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of rotary primary and secondary cam die, comprise lower mould body and upper mould body, be provided with the whole die plate insert of side and the removable cover of cut-off rule between also comprising, described lower mould body is provided with the whole die plate insert drive block of rotation side of the whole die plate insert rotation of driving side, described upper mould body is provided with and drives the slotting tool that the removable cover drive block moves horizontally, and the removable cover drive block slides to be located at and drives removable cover on the whole die plate insert of side and move along cut-off rule.
Described slotting tool is provided with slotting tool stroke backboard, and described removable cover drive block is provided with removable cover drive block stroke backboard, and described slotting tool stroke backboard matches with removable cover drive block stroke backboard inclined-plane.
The whole die plate insert of described side is provided with the whole die plate insert stroke of side backboard, the whole die plate insert drive block of described rotation side is provided with the whole die plate insert drive block of rotation side stroke backboard, and the whole die plate insert drive block of described rotation side stroke backboard outer end is provided with the inclined-plane suitable with the whole die plate insert stroke of side backboard inner end.
The inclined-plane matches between described removable cover drive block and the removable cover.
Be provided with guide plate between described removable cover drive block and the whole die plate insert of side.
Described removable cover and removable cover drive block are located in the whole die plate insert of side.
The present invention compared with prior art, have the following advantages: removable cover is movable, and removable cover withdraws from certain distance along the cut-off rule with the whole die plate insert of side first, then jointly rotates with the whole die plate insert of side, eliminate product and take out interference point, be convenient to product and take out smoothly; The cut-off rule of the whole die plate insert of side and cover plate, the intensity of assurance removable cover, the while has also guaranteed effective press face of the whole die plate insert appearance of side; Realize the function that product can't be realized at the fixed cover plate of tradition, promoted the development of product, promoted the security performance of vehicle body.
