Description

Apparatus for forming the upper and bottom plates of metallic vessel

The present invention relates to an upper and lower plate forming apparatus of a metal container for molding the upper and lower plates attached to the upper and lower edges of various metal containers made of a rectangular shape. In more detail, the transfer and horizontal calibration step of the molded material wound in a roll type, and the upper and lower horizontal sides and the corners of the molded material in the transfer direction are "

"The processing step to chamfer and the molding material"

"The upper and lower plates which have undergone the chamfering processing step in the form pass through a pair of printing rollers to apply a printing layer to the upper surface of the printing step, and the upper and lower plates, which are coated with the printing layer on the upper surface of the upper and lower plates, pass through the lifting means of the drying furnace. The drying step of drying the layer is characterized in that the upper and lower plates can be molded by an integrated process.
In particular, the present invention is directed to the upper transfer die "

"On the chamfer cut with the corresponding lower fixing die"

"On the upper and lower horizontal sides and the four corners of the upper and lower plates in the conveyance progressing direction by the chamfering processing step of the press in which the recesses of the mold are formed as shown in FIG.

"Scrap scrap is generated, which can reduce the material loss of molding materials to the minimum, reduce the production cost of products, facilitate the work by batch process, and increase the productivity of unit time. Of course, it is possible to mass-produce high quality products by preventing defective products.

Conventionally, as a top and bottom plate forming apparatus of this type of metal container, in order to prevent the top and bottom plates from being rusted, a molding material made of a steel sheet of 776 mm × 770 mm in width / length, which is coated and printed on one surface by a shearing step, is transversely formed. Cut into three parts according to the standard and put the sheared molded material on the feeder's loading stand, and then the sheared molded material is transferred to the press by the operation of the air cylinder according to the mechanical drive, and the molding is transferred to the press. The material is cut by the blanking die consisting of the upper punch and the lower die, and the upper and lower scraps are cut as shown in FIG.

"Blank in shape and the upper and lower plates were molded.
However, since the paint layer is not coated and printed to prevent rust on the molding material itself, a separate step of coating and printing the paint layer on one surface of the molding material is required. In order to request printing to a subcontractor to apply a paint layer on one side of the molded material, the printing material is recovered and the top and bottom plates are molded and recovered. It required a large number of people, and as a result, deterioration of the work efficiency caused not only the productivity of the unit time to be lowered, but also a rise in the cost of the product due to the increase in labor costs, and the economic burden on the real users.

As described above, when the upper and lower plates are formed in the molding material by forming a chamfer cut of the lateral edge and the square by the chamfer cut and the corresponding recessed portion by the press consisting of the upper movable die and the lower fixed die, as shown in FIG.

"It is possible to reduce the loss of molding materials by reducing the shape of the molding material, reduce the production cost, increase the productivity of the unit time and prevent the defective products to mass-produce high-quality products by the batch operation process. The purpose is to provide a top and bottom plate forming apparatus of a metal container to be able to.

In the present invention, in forming a top and bottom plate attached to the upper and lower edges of a rectangular metal container by processing a roll-type molding material made of a metal plate, while the molding material that is the material of the top and bottom plate is transferred by a feeder by one pitch A horizontal calibration step, wherein the molding material being conveyed by one pitcher by the feeder passes through a press consisting of an upper movable die and a lower fixed die, and is transported by a chamfer cut of the upper movable die and a recess of the corresponding lower fixed die. Molding material in the direction of the top and bottom side and only the corner

"Chamfering processing step of generating a scrap of the type, the printing step of coating the coating layer on one surface while passing through the pair of rollers through the chamfering processing step, the upper and lower plates through the printing step inside the furnace by the lifting means It characterized by consisting of the step of drying the coating layer coated on the upper and lower plate while lifting and transporting.

According to the present invention, the roll-type molding material is horizontally corrected by one pitcher by the feeder, and the upper and lower edges and the corners of the transfer progress direction in the upper moving die and the lower fixing die are chamfered, as shown in FIG.

The upper and lower plates are scrap-shaped and proceed in the conveying direction while the paint layer is coated and printed on one surface while passing through the printing means. Since it can be molded, the work efficiency of the unit time is improved, so that the productivity can be increased, and the time and manpower according to the work can be reduced to the minimum, and the quality can be mass-produced by preventing defective products. Compared to this, the amount of scrap generated is small, so that the material loss of the molding material can be reduced to a minimum and the production cost can be reduced accordingly, thereby reducing the economic burden on the consumer.
