Description

Lower driving mechanism for continuous in-mold buckle forming

Technical Field

The utility model relates to an automobile stamping die field specifically is a put actuating mechanism under continuous mould internal buckling shaping.

Background

Progressive dies are a very common type of die in the field of automotive stamping dies. The continuous die has the advantages of high production automation, high product precision, high production speed and the like. The most direct influence on the production speed is the stroke of the stamping die. In the first aspect, the lower the designed die stroke is, the faster the stamping speed can be theoretically achieved in the production of the same die, which has a great influence on the production cost. In a second aspect, the stamping device is limited by the design, the stroke that can be achieved is limited to an upper limit, and unlimited opening is not possible, so that the stroke of the stamping die can be designed not to exceed the maximum stroke of the stamping device. In a third aspect, too high a die stroke can have various adverse consequences, such as the die can be designed to be taller and larger, resulting in increased manufacturing costs, decreased die stability with too high a stroke, too long a nitrogen spring, premature damage due to decreased perpendicularity, and the like.

As mentioned above, it is reasonable to design the die stroke at a lower reasonable value. However, in actual design, in addition to the swaging stroke and the floating stroke necessary for restricting the product shape, there are cases where the increase in the die design stroke is caused. For example, when the product is formed with an inner buckle, the wedge is generally designed to produce the inner buckle surface. Generally, two groups of wedges are arranged, and a forming female die and a forming male die are respectively arranged on the wedges. When the mechanism works, a product is pressed by the pressure plate, then the wedge with the forming female die moves to push the forming female die to the position, and finally the forming male die moves to finish the forming action.

Because two sets of wedges need time difference, the pressing stroke is increased, and the necessary floating stroke is added, the total stroke of the die with the inner buckle is usually larger finally, even the total stroke value exceeds the maximum stroke of the original punch sometimes, and finally, a larger punch has to be replaced to provide a larger stroke, so that the production cost is increased.
