Abstract
The invention provides a terrace die core for vehicle ceiling with good universality and a using method thereof; the terrace die core for vehicle ceiling is able to solve the problem that the ceiling with skylight collapse when producing vehicle ceilings with and without the skylight by a common die. The terrace die core for vehicle ceiling comprises a terrace die core body, a slide plate, and a drive mechanism for driving the slide plate to slide along the top surface of a lower die seat; the top of the slide plate and the bottom of the terrace die core body are provided with wedge stroke back plates which are mutually matched; a vertical guide limiting mechanism is arranged between the terrace die core body and the lower die seat, so as to change the height of the terrace die core body when the slide plate slides along the top surface of the lower die seat. The using method of the terrace die core for vehicle ceiling is as follows: when producing the ceiling with the skylight, using the drive mechanism to drive the slide plate move along a first direction, lifting up the terrace die core body to a preset height H1; when producing the ceiling without the skylight, using the drive mechanism to drive the slide plate move opposite to the first direction, reducing the terrace die core body to a preset height H2; the H1 is greater than the H2.
Description
Technical field
The invention belongs to automobile panel cold punching technology field, be specifically related to a kind of automobile cold-stamped part mould and using method thereof.
Background technology
Under prior art condition, band skylight top cover adopts common mode to produce with two kinds of products not with skylight top cover, and the convex mould core structure of conventional fixed-type cannot meet the adjustment that two kinds of products subside, specific as follows:
Because adopt common mode to produce, fixed punch benevolence profile makes according to not being with skylight top cover profile, causing the product after being with skylight vehicle top cover to rush skylight hole to subside subsides greatly than the vehicle top cover not with skylight, solution can not compensated by punch benevolence profile with subsiding of skylight, and the top cover with skylight causes the additional amount of subsiding cannot to compensate at postorder mould because having rushed hole, add the difficulty of mating with skylight stiffener.
Under traditional moulds process condition, the solution of the problems referred to above is: band skylight top cover increases separately the operation of one skylight flange, and subside to solve skylight, obvious this scheme haves no alternative but add frock development cost and production cost.
Above-mentioned situation seriously constrains the development of vehicle exterior cladding element mould, current most of automobile main frame maker is subject to the impact of frock cost and production cost, top cover band skylight be not with skylight to adopt common mode to produce, be with the top cover in skylight by developing separately, the solution problem of subsiding can not put up with.But along with consumer is to the lifting day by day of presentation quality, band skylight top cover collapse-deformation problem, becomes again the day by day urgent problem solved.
Summary of the invention
The object of the invention is to propose the good automobile top-cap punch benevolence of a kind of versatility and using method thereof, this automobile top-cap punch benevolence can solve band skylight top cover with when not being with skylight top cover common mode to produce, the problem that band skylight top cover subsides.
Automobile top-cap punch benevolence of the present invention comprises punch benevolence body, and key is that described automobile top-cap punch benevolence also comprises slide plate and the driving mechanism for driving slide plate to slide along die shoe end face; The top of described slide plate and the bottom of punch benevolence body are provided with the wedge stroke backboard cooperatively interacted, and are provided with vertically-guided position-limit mechanism between described punch benevolence body and die shoe, change height to make punch benevolence body when slide plate slides along die shoe end face.
Vertically-guided position-limit mechanism makes punch benevolence body to rise relative to die shoe or to decline, and can not move by relative level.At wedge stroke backboard in the process of slide plate movement, its inclined-plane can interact, thus lifting is positioned at the height of the wedge stroke backboard of top, achieves the change of punch benevolence body height.
The using method of above-mentioned automobile top-cap punch benevolence is as follows: when producing band skylight top cover, driving mechanism is utilized to drive slide plate to move to first direction, by the effect of wedge stroke backboard and vertically-guided position-limit mechanism, lifting punch benevolence body is to predetermined altitude H1; When produce be not with skylight top cover time, utilize driving mechanism drive slide plate dorsad first direction move, by the effect of wedge stroke backboard and vertically-guided position-limit mechanism, reduce punch benevolence body to predetermined altitude H2; Described H1 is greater than H2.Concrete principle is as follows: when produce band skylight top cover time, punch benevolence upwards jack-up to compensate the amount of subsiding; When skylight top cover is not with in production, punch benevolence reduces, its profile empty avoiding product, and solid punch benevolence profile supports the top cover not with skylight.
Further, described automobile top-cap punch benevolence also comprises the guide plate being fixedly installed in die shoe end face, be provided with gap between described guide plate with die shoe end face to form the gathering sill parallel with described slide plate moving direction, the edge movable of described slide plate is stuck in gathering sill.Above-mentioned gathering sill can limit slide plate and rock, and then ensures the controllability of punch benevolence body.
Further, the working face of described wedge stroke backboard is formed by connecting by inclined-plane and horizontal plane, above-mentioned inclined-plane is for changing the height of punch benevolence body, and the height of horizontal plane designs according to concrete requirement, to make the two pieces of wedge stroke backboards cooperatively interacted when horizontal plane offsets, the height of punch benevolence body meets the requirement to punch benevolence body height when producing band skylight top cover just, and can ensure like this in the process of punching press, wedge stroke backboard can be stablized and can not move.
Further, described vertically-guided position-limit mechanism is made up of the projection and the guide rail be fixed on die shoe being fixed on punch benevolence body side, and described guide rail is provided with vertical channel, and described projection activity is stuck in vertical channel; Described vertically-guided position-limit mechanism has multiple, and is distributed in the surrounding of punch benevolence body.The surrounding of punch benevolence body is equipped with vertically-guided position-limit mechanism, can ensure the stability of the horizontal level of punch benevolence body.
Further, described driving mechanism is cylinder, or described driving mechanism is the screw rod driven by stepper motor, and described slide plate is provided with the nut coordinated with described screw flight.Adopt cylinder to be that control is quick, convenient as the benefit of driving mechanism, and the benefit utilizing the structure of screw rod and nut screw connection to be used as driving mechanism is the displacement that accurately can control slide plate, thus accurately controls the height of punch benevolence body.
Automobile top-cap punch benevolence design of the present invention is ingenious, manufacture is simple, cost is low, is convenient to apply, and under the prerequisite reducing die procedure number, thoroughly solves band skylight top cover with when not being with skylight top cover common mode to produce, is with the problem that skylight top cover subsides.The present invention, not only for outer covering pieces such as automobile top-caps, is also suitable for other similar stamping parts equally, has the larger scope of application.
