The convex hull order comprises an upper support (1), a concave die (5), a pressure plate (8) and a base (10); a guide pole (4) is arranged between the upper support (1) and the base (10); the two ends of the guide pole (4) are connected with the upper support (1) and the base (10); the guide pole (4) is provided with a guide sleeve (11); a fixed plate (2) is fixed at the bottom of the upper support (1); a spring (6) is arranged between the fixed plate (2) and the pressure plate (8); the two ends of the spring (6) are connected with the fixed plate (2) and the pressure plate (8); the concave die (5) is positioned under the pressure plate (8); a spring (12) is arranged between the concave die (5) and the base (10); the two ends of the spring (12) are connected with the base (10) and the concave die (5); a stretching convex die (7) is arranged under the fixed plate (2); the pressure plate (8) is provided with a through hole a (13) at the position corresponding to the stretching convex die (7); a spherical pit (14) is arranged on the concave die (5) at the position corresponding to the through hole; and the bottom end of the stretching convex die (7) is matched with the pit. The central bracket of the car radiator produced by the stamping die has more complicated stretching moulding surface and higher rupture prevention capability.

Description

The convex closure preface of car radiator center bearing bracket diel
Technical field
The utility model belongs to the diel field, relates to the diel of a kind of car radiator center bearing bracket, particularly relates to the convex closure preface of a kind of car radiator center bearing bracket diel.
Background technology
Common car radiator center bearing bracket tends to open a very big technology breach in order to satisfy existing mould technology in the support lower corners, thereby causes this place's intensity to weaken.Also do not reach the reliability fare register at automobile, the radiator center bearing bracket just can often produce the problem of bottom fracture.The diel of existing manufacturing radiator center bearing bracket is made up of blanking punching preface (first preface), moulding preface (second preface), side blow preface (the 3rd preface), this mould was once carried out the improvement of four kinds of methods, maybe can not satisfy the problem that entrucking requires but its product of producing has breach, not have application prospect.
Summary of the invention
Technical problem to be solved in the utility model is to open the problem of the support bottom fracture that a very big technology breach produces because of radiator center bearing bracket lower corners, and provide the diel of a kind of improved car radiator center bearing bracket, this mould has increased the convex closure preface before the blanking punching preface of former radiator center bearing bracket diel, the concrete structure of this preface is as follows:
The convex closure preface of a kind of car radiator center bearing bracket diel, comprise pop-up, die, holding pad, base, be provided with guide pillar between pop-up and the base, the guide pillar two ends are connected with base with pop-up, guide pillar is provided with guide pin bushing, fixed head is fixed on the pop-up bottom, be provided with spring between fixed head and the holding pad, both ends of the spring is connected with holding pad with fixed head, and die is positioned at the holding pad below, be provided with spring between die and the base, both ends of the spring and base and recessed symphysis connect, and fixed head has the amplification punch, are provided with through hole with amplification punch corresponding section on the holding pad, be provided with spherical pit with this through hole corresponding section on the die, amplification punch bottom and this pit are suitable.
After adopting this structure, earlier plate is placed between holding pad and the die, then pop-up is moved downward along guide pillar, thereby drive amplification punch passes the through hole on the holding pad, and inserts the spherical pit on the die, makes plate form a technology convex closure, in advance plate (support corner) is evenly stretched and open, make moulding preface technology have abundant plate to replenish into, reduce the technology breach greatly, finally improve the intensity of radiator center bearing bracket corner.
Forming a convex closure in car radiator center bearing bracket corner can make the convex closure position when bending, there are enough plates to replenish, can not cause this place's plate to move untimely because of complicated moulding, cause the excessive attenuation of local thickness, and cause the phenomenon that plate cracking and intensity weaken, thereby significantly reduce the technology breach of this support corner, improve intensity.
As preferably, also be provided with drift under the fixed head, be provided with through hole b with the drift corresponding section on the holding pad, be provided with through hole c with this through hole corresponding section on the die, when the amplification punch arrived pit bottom, through hole c was inserted in the drift bottom.
After adopting this structure, earlier sheet material is placed between holding pad and the die, then pop-up is moved downward along guide pillar, thereby the drive drift passes the through hole b on the holding pad, and the through hole c on the insertion die, make plate form the hole, this hole can make the radiator bearer lower end be fixed on firmly on the radiator sill.
When the amplification punch arrived pit bottom, through hole c was inserted in the drift bottom, and this forms the problem that causes the plate between technology convex closure and the hole to be stretched with regard to having been avoided simultaneously because of the hole on technology convex closure and the plate.
Description of drawings
Accompanying drawing 1 is the sectional view of the convex closure preface of a kind of car radiator center bearing bracket diel.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1
A kind of convex closure preface of car radiator center bearing bracket mould, this preface mould comprises pop-up 1, die 5, holding pad 8, base 10, be provided with guide pillar 4 between pop-up 1 and the base 10, guide pillar 4 two ends are connected with base 10 with pop-up 1, guide pillar 4 is provided with guide pin bushing 11, fixed head 2 is fixed on pop-up 1 bottom, be provided with spring 6 between fixed head 2 and the holding pad 8, spring 6 two ends are connected with holding pad 8 with fixed head 2, die 5 is positioned at holding pad 8 belows, be provided with spring 12 between die 5 and the base 10, spring 12 two ends are connected with recessed film 5 with base 10, and fixed head 2 has amplification punch 7 and drift 3, are provided with through hole a13 with amplification punch 7 corresponding sections on the holding pad 8, be provided with spherical pit 14 with through hole a13 corresponding section on the die, amplification punch 7 bottoms and this pit are suitable, are provided with through hole b15 with drift 3 corresponding sections on the holding pad 8, are provided with through hole c16 with through hole b15 corresponding section on the die 5, the degree of depth of pit is 18mm, and the length of drift is than the little 16mm of length of amplification punch.
During use, earlier plate is placed between holding pad 8 and the die 5, then pop-up 1 is moved downward along guide pillar 4, thereby drive drift 3 and amplification punch 7 pass the through hole on the holding pad, and insert respectively on the through hole c16 and pit 14 on the die, make plate form hole and technology convex closure.
