Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.

Referring to fig. 1 to 3, an embodiment of the present invention includes:

an automatic material lifting type stamping die comprises a top plate 1, an upper die 2, a lower die 3, a bottom plate 4 and an arc hook plate 7. The lower die 3 is fixed on the bottom plate 4, and the upper die 2 is connected with the top plate 1. The lower die 3 is provided with a mounting hole; be equipped with in the mounting hole and be used for going up the guide pillar 5 of mould lift direction, go up and be equipped with the guide pin bushing 6 that cooperates guide pillar 5 on the mould 2, go up mould 2 and cooperate guide pillar 5 through guide pin bushing 6. Two guide posts 5 are arranged, and the two guide posts 5 are matched on the upper die 2 through guide sleeves. The lower die 3 is provided with a punch forming processing area which penetrates along the width direction of the lower die. The center in processing district is equipped with bellied locating piece, is equipped with circular-arc constant head tank on the locating piece, and this constant head tank is used for being processed the location of work piece, prevents to influence the shaping effect because of the position removes among the stamping process. And a supporting spring 10 is also arranged between the upper die and the top plate, and can stabilize the downward pressure and reduce the die collision. Still be equipped with on the length direction both sides terminal surface in processing district and be used for mould positioning groove, go up and still be equipped with an arc hook 7 that is used for the material of lifting on the mould 2, arc hook 7 is equipped with and resumes the arc district of deformation to the mould direction. The upper end head of the arc hook plate 7 is fixed on the top surface of the upper die 2 through a rotating shaft 11; an extension spring 8 is arranged between the upper end of the arc hook plate 7 and the top surface of the upper die 2; the extension spring 8 supports the upper end of the arc hook plate 7 so that the lower end of the arc hook plate 7 does not generate pressure. The lower end of the arc hook plate 7 is a hook end, the hook end is lower than the bottom surface of the upper die 2, and a cylindrical rubber head is arranged at the end head of the hook end. An I-shaped groove 9 matched with the arc hook plate is arranged on the side surface of the lower die 3, the I-shaped groove 9 leads to the bottom surface in the processing area, and the rubber head is clamped into the I-shaped groove 9 and slides out from an I-shaped notch on the bottom surface in the processing area. The hooking end is an arc bending upwards towards the direction of the die, the hooking end forms a barb shape, when the top plate 1 drives the upper die 2 to press downwards, the top plate 2 compresses the supporting spring 10, and the upper die 2 and the lower die 3 are matched with each other to punch a workpiece. Meanwhile, the top plate 1 presses the upper end of the arc-shaped hook plate 7, the upper end of the arc-shaped hook plate 7 overcomes the action of the telescopic spring 8, the arc-shaped hook plate 7 rotates downwards around the rotating shaft 11 of the upper end, the upper die and the lower die are in a die closing state at the moment, and the rubber head of the arc-shaped hook plate 7 is clamped into the lower port of the I-shaped groove 9. After the sheet product is formed, the top plate 1 is driven to ascend, the top plate 1 simultaneously leaves from the upper end of the arc hook plate 7, the expansion spring 8 recovers the jacking force on the upper end of the arc hook plate, the hooking end of the arc hook plate 7 is just matched in the I-shaped groove 9 at the moment, the arc hook plate 7 is matched with the upper die 2, the kinetic energy of the upper die 2 in resetting is utilized, and the workpiece is hooked from the processing area of the lower die 3 by matching with the deformation force of the arc hook plate 7. The hooked end can leave the side face of the lower die 3 along with deformation force after sliding out from the upper port of the I-shaped groove 9, and collision is avoided. Arc hook plate 7 is the sheet material of spring steel material, and arc hook plate 7 has an arc district at least, and the deformation power in arc district resumes the direction all be the mould direction promptly processing district inboard direction, and it helps colluding the work piece. The end of the hooking end is provided with a rubber head which can increase friction and reduce the scraping damage to the die. This punching die liftout cooperates through arc hook plate, and arc hook plate 7 colludes the work piece under the elastic force effect, realizes the automatic landing of tablet, has reached the automatic mesh of taking off the material, and whole process is automatic to be accomplished, reduces the work load of getting the material, and whole process is accomplished at the ascending in-process of upper die in addition, has improved production efficiency.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
