Lower mold structure for stamping and flanging in box cap forming process

Abstract

The invention relates to a lower mold structure for stamping and flanging in a box cap forming process. A horizontal lower mold base plate is provided with a rectangular-frame-shaped lower mold, the lower mold is transversely provided with two parallel conveyer chains, both ends of the conveyer chains are positioned outside the lower mold, the conveyer chains can be synchronously moved in the vertical direction, the highest position which the conveyer chains can be moved to is located above the lower mold, the lowest position which the conveyer chains can be moved to is located below the stamping surface of the lower mold, two long through grooves extending downwards are respectively arranged on the lower mold in the length directions of the conveyer chains, and the vertical projections of the conveyer chains on the lower mold are located in the thorough grooves. By using the conveyer chains extending through the whole lower mold to convey materials, an enough conveyance distance can be ensured, thereby being beneficial to the output of finished products; compared with conveyer belts, the conveyer chains are less prone to skid, and the seizure or failure to convey out finished products due to the off-tracking of materials caused by the insufficient conveyance force can be avoided; and the conveyer chains are in a structure capable of moving in the vertical direction, so that the conveyer chains can be moved up to convey the materials in the conveyance process, and can be moved down in the stamping and flanging process so as to prevent the mold from being interfered with by stamping and flanging, thereby ensuring the flexible and maneuvering conveyance.

Description

technical field [0001] The invention relates to a die-closing forming device, in particular to a stamping flanging lower die structure for box cap forming. Background technique [0002] Box caps are mainly used for the outer packaging of tin-plated steel sheets. The existing equipment for producing box covers is mainly box cover forming machines. The production process includes sheet cutting, manual feeding, automatic blanking, and stamping and flanging. The blank after shearing is a rectangular plate of standard size, and then it is manually loaded onto a quadruple punching machine, and the two ends of the rectangular plate are punched out into two symmetrical polygons along the longitudinal and horizontal directions, and then punched out. Then the finished plate is punched and flanged into a three-dimensional box cap product. [0003] The mold clamping equipment used in the stamping and flanging process consists of three parts: the power unit, the upper mold assembly, and...

AI Technical Summary

Problems solved by technology

[0005] In the actual production process, because the conveying belt is arranged inside the lower mold, the conveying distance is limited, and because the conveying belt is easy to slip, it often happens that the finished box cap output deviates or even gets stuck in the structure of the lower mold, and the finished box cap cannot be smoothly conveyed In some cases, it is necessary to manually take out the finished products for stacking, which is not conducive to the continuous production of box cap products
