Abstract
The invention relates to a blank supporting device for a hot stamping die. The blank supporting device comprises a supporting seat, a carrying rod and return springs. The supporting seat consists of a base and double risers; the carrying rod is arranged between the double risers by a hinge pin; the carrying rod can rotate around the hinge pin; the rear part of the carrying rod is provided with a connecting pin running through both sides of the carrying rod; two return springs are respectively arranged outside the risers; and one ends of the return springs are connected with the connecting pin and the other ends of the return springs are connected and fixed with connecting pillars arranged outside the risers. According to the invention, the carrying rod supports a hot-stamped high temperature blank on a die face under the action of the return springs, can rotate around the hinge pin in the stamping process and is returned by drawing forces of the return springs in the return stage of a stamping press. The blank supporting device has a simple structure; the high temperature blank can be effectively supported; contact between the hot blank and the die face before stamping is avoided; the blank supporting device can be rapidly reset; and the blank supporting device is suitable for standard blank supporting of the hot stamping die.
Description
Technical field
The present invention relates to hot stamping die blank Holder Fasteners, is a kind of hot stamping die blank bracing or strutting arrangement concretely.
Background technology
At present hot stamping die mainly carries out coolingly to die surface and high temperature blank by the die surface cooling circuit, realizes quenching process in mould, obtains uniform martensitic structure, the tensile strength stamping parts higher than 1400MPa.The high temperature blank that the Quick mechanical hand will be heated to austenitizing is placed on mould surface, for fear of contacting of hot blank before punching press and die face, need to adopt support component the drop stamping blank to be positioned to the position of die surface certain distance, for fear of the too much heat transfer of supporting member and blank, should reduce the contact area between them as far as possible.Up to now, also there is no special-purpose hot stamping die blank bracing or strutting arrangement on market.
Summary of the invention
Technical problem to be solved by this invention is in order to overcome above-mentioned the deficiencies in the prior art, a kind of simple structure is provided, easy to use, can effectively support the high temperature blank, before avoiding punching press, hot blank contacts with die face, but and the hot stamping die blank bracing or strutting arrangement of Rapid reset.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of hot stamping die blank bracing or strutting arrangement, comprise supporting seat, retainer bar and back-moving spring, it is characterized in that: described supporting seat is comprised of base and two riser, the retainer bar is arranged in the middle of two risers by bearing pin, the retainer bar can rotate around bearing pin, retainer bar rear portion is equipped with a connecting pin that runs through both sides, two back-moving springs are arranged on respectively the riser outside, back-moving spring one end is connected with connecting pin, and the joint pin that the other end and the riser outside are provided with is connected and fixed.
Riser of the present invention is provided with spacing shoulder.It coordinates with connecting pin on the retainer bar, is used for limiting the anglec of rotation of retainer bar around bearing pin, makes it under the stretching of back-moving spring, horizontal support high temperature blank.
Base of the present invention is provided with bolt hole, and base is bolted on the mould bases of mould.
Supporting seat of the present invention directly is fixedly connected with mould bases, the retainer bar, under the effect of back-moving spring, is supported on drop stamping high temperature blank on die face, and can in punching course, around bearing pin, rotate, and, in the die cutting press backhaul stage, rely on the tensile force of back-moving spring that the retainer bar is resetted.Against existing technologies, the present invention has simple in structure, can effectively support the high temperature blank, avoids hot blank before punching press to contact with die face, but and Rapid reset, the advantages such as reliable operation.Being suitable for the standardized blank of hot stamping die supports.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is that the present invention forms structural representation.
Fig. 2 is that schematic diagram is looked on the left side of Fig. 1.
Label in figure is: 1. retainer bar, 2. bearing pin, 3. connecting pin, 4. back-moving spring, 5. supporting seat, 51. risers, 511. spacing shoulders, 512. joint pins, 52. bases.
The specific embodiment
From Fig. 1, Fig. 2, can find out, a kind of hot stamping die blank bracing or strutting arrangement, comprise supporting seat 5, retainer bar 1 and back-moving spring 4.Described supporting seat 5 is comprised of base 52 and a pair of riser 51, retainer bar 1 is arranged in the middle of two risers 51 by bearing pin 2, retainer bar 1 can be around bearing pin 2 rotations, retainer bar 1 rear portion is equipped with a connecting pin 3 that laterally runs through retainer bar both sides, symmetrically arranged two back-moving springs 4 are arranged on respectively riser 51 outsides, back-moving spring 4 one ends are connected with connecting pin 3, and the joint pin 512 that the other end and riser 51 outsides are provided with is connected and fixed.
Supporting seat of the present invention directly is fixedly connected with mould bases, rely on the retainer bar that the high temperature blanks such as high-strength boron steel plate of austenitizing are supported on die face, avoid the high temperature blank directly to contact with mould, and can in punching course, around bearing pin, rotate, and, in the die cutting press backhaul stage, rely on the tensile force of back-moving spring that the retainer bar is resetted.During concrete the use, the Quick mechanical hand is placed in the high temperature blank of austenitizing on retainer bar 1, and during matched moulds, under the effect of stamping press, the retainer bar rotates around bearing pin, until 90-degree rotation is contracted in two riser intermediate gaps, removes the support to the high temperature blank.Meanwhile back-moving spring is stretched.This process completes the shaping of heat-punch member, after one section keeps pressure, completes interior quenching of mould of stamping parts.During die sinking, the retainer bar is homing under the pulling force effect of back-moving spring, until on retainer bar 1, connecting pin contacts with riser 51 upper limit shoulders 511.
The present invention has simple in structure, can effectively support the high temperature blank, avoids hot blank before punching press to contact with die face, but and Rapid reset, the advantages such as reliable operation.Being suitable for the standardized blank of hot stamping die supports.
