Technical Field

The invention relates to a continuous stamping die, in particular to a continuous stamping die with a multiple stripping mechanism.

Background

The punching die is a pressure processing method for obtaining required parts by applying pressure to materials by using a die arranged on a press machine in the cold punching processing process to cause the materials to be separated or plastically deformed, and the punching die can be divided into an engineering die and a progressive die. The engineering die is a stamping die which can only complete one working procedure of a part in one die; the progressive die is a press die that performs two or more simple processes in one die.

After a stamping process is completed for one time, the material to be stamped is moved to the next stamping position for continuous stamping, and in order to ensure that the material is smoothly moved to the next stamping position, the material needs to be separated from the upper die and the lower die of the stamping position. The existing die only takes off the material through setting up the stripper plate, and the stripping effect is not good, which affects the continuity of stamping.

Disclosure of Invention

In view of the above, the invention provides a continuous stamping die with a multiple stripping mechanism, which solves the problem that the stripping effect of a stripping plate is poor after the stamping of the continuous stamping die is completed.

To this end, the invention provides a continuous stamping die with a multiple stripping mechanism, comprising:

the upper die mechanism comprises an upper die base, an upper die plate and a stripper plate, the upper die plate is fixedly arranged at the bottom of the upper die base, a punch assembly is arranged at the bottom of the upper die plate, the stripper plate is elastically connected to the upper die base, the punch assembly penetrates through the stripper plate, a first material pushing block is arranged at the bottom of the stripper plate, and the first material pushing block is elastically connected to the stripper plate;

and the lower die base is provided with a second pushing block corresponding to the first pushing block, and the second pushing block is elastically connected to the lower die base.

Further, the punch assembly includes a first punch, a second punch, a third punch, a fourth punch, and a fifth punch arranged in this order in the material conveying direction.

Furthermore, a plurality of first guide columns are arranged on the upper template, and first column holes corresponding to the first guide columns are arranged on the lower die holder.

Furthermore, two rows of second guide post mechanisms which are arranged in parallel are arranged on the lower die base, each second guide post mechanism comprises a plurality of second guide posts which are arranged along the material conveying direction, and second post holes corresponding to the second guide posts are formed in the stripper plate.

Furthermore, a plurality of positioning blocks are arranged on the lower die base, and positioning holes corresponding to the positioning blocks are arranged on the stripper plate.

Further, a plurality of third material pushing blocks are arranged at the bottom of the stripper plate.

Further, a plurality of third pushers are arranged in parallel along the material conveying direction.

Further, the end section of the third material pushing block is arc-shaped.

The invention provides a continuous stamping die with a multiple stripping mechanism, which comprises the following stamping processes: the upper die mechanism moves downwards, the stripper plate extrudes the material on the lower die base, the first punch, the second punch, the third punch, the fourth punch and the fifth punch on the upper die plate punch the material, and blanking holes corresponding to the punches are formed in the lower die base. The first material pushing block and the second material pushing block are symmetrically extruded on the surface of the material. After punching is completed, the upper die mechanism moves upwards, the stripper plate separates materials from the punches and moves upwards, the first material pushing block ensures that the materials are separated from the stripper plate, and the second material pushing block enables the materials to be separated from the lower die base. The stripper plate is matched with the first material pushing block and the second material pushing block, so that the stripping effect of the stamping die is good, and the material moves smoothly. The first material pushing block and the second material pushing block are symmetrically arranged, so that the mold is not easy to deform during stripping. The first guide columns can ensure the matching precision of the upper die mechanism and the lower die holder.

The continuous stamping die with the multiple stripping mechanisms provided by the invention solves the problem of poor stripping effect of the stripping plate after the stamping of the continuous stamping die is finished, and ensures the continuity of the stamping.
