Abstract

The utility model discloses an H-shaped integrated type stamped connecting piece used for thin-film packaging. The H-shaped integrated type stamped connecting piece comprises a concave groove body, wherein the concave groove body is provided with an opening facing downwards, and a plurality of layers of clamp plates can be inserted into the concave groove body. The concave groove body comprises a groove bottom and groove walls. Opposite through holes are punched in two groove walls of the concave groove body. A concave groove is formed in the upper portion of the groove bottom of the concave groove body, wherein the concave groove is formed by upwards bending of metal sheets inside the through holes which are integrated with the groove bottom, and the plurality of the layers of the clamp plates can be inserted into the concave groove. The upper surface and the lower surface of the groove bottom are respectively provided with at least one protrusion. The H-shaped integrated type stamped connecting piece is low in manufacturing cost, and capable of meeting requirements of the thin-film packaging and completely replacing an H-shaped aluminum section which is high in cost.

Description

H type integral type punching press link

Technical field

The utility model relates to a kind of H type integral type punching press link.

Background technique

In polyester film manufacturing enterprise, adopt of packing before polyester film dispatches from the factory is contained in the refill two ends that are wound with polyester film with the square multi-layer plywood sleeve more, then will need the multireel film level with multiply-plywood of packing stacking, multiply-plywood is by the mutual clamping of H type aluminium section bar, again stacking good film roll is packaged with wrapper and get final product, but H type aluminium section bar cost is higher.

The model utility content

The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of H type integral type punching press link is provided.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of H type integral type punching press link, comprise that Open Side Down and can insert the groove body of multiply-plywood, described groove body comprises bottom land and cell wall, described groove body two cell wall upper punches are pressed with relative through hole, described groove body bottom land top has in the through hole and the make progress groove of the inserted multiply-plywood that bending forms of the sheetmetal of bottom land one, and the upper and lower surface of described bottom land has respectively at least one projection.

Projection is the burr that forms after the punching on the bottom land, and the upper and lower surface of bottom land has respectively two projections.

The beneficial effects of the utility model are: the H type integral type punching press link that the utility model provides, low cost of manufacture can satisfy the requirement of wrapping film, can replace the higher H type aluminium section bar of cost fully.
