A processing method for integrally forming a steel plate box cover

Abstract

The invention relates to an integrated forming processing method for a steel plate box cover, and belongs to the technical field of processing of steel plate box covers. The integrated forming processing method for the steel plate box cover is characterized by comprising the following steps: 1) automatically feeding: using a vacuum sucker type automatic feeding device for horizontally feeding a steel plate; 2) shearing in a punching manner and turning upwards corners: using a four-linkage corner punched-shearing and upward-turning device to shear in a punching manner four corners of the steel plate, using an upper die of the corner punched-shearing and upward-turning device to shear in a punching manner a pair of triangular plate materials of each corner, using a lower die (1a) of the corner punched-shearing and upward-turning device to jack up, and to synchronously turn upwards the four corners of the steel plate; 3) forming the box cover in a punching manner: using a punch forming device (2) to turn the periphery of the steel plate inwards to form a finished product steel plate box cover. The method provided by the invention not only avoids the phenomenon of exposure of burrs on the box cover formed in a punching manner, but also enables the operations of punched shearing and turning upwards to be carried out simultaneously, so that one processing step is saved.

Description

technical field [0001] The invention relates to a processing method for integrally forming a steel plate box cover, which belongs to the technical field of steel plate box cover processing. Background technique [0002] The steel plate box cover is mainly used for the outer packaging of the steel plate, and it is placed on top of a stack of steel plates to protect the package. [0003] The existing equipment for producing box lids is mainly box lid forming machines, and its production process includes sheet metal cutting, manual feeding, automatic blanking, corner turning up and pressing, and stamping and flanging forming. After the sheet is cut, the blank is a rectangular plate of standard size, and then manually loaded to the quadruple punching machine, the two ends of the rectangular plate are punched out to form a product plate with two symmetrical sides in the vertical and horizontal directions, and then the finished plate is stamped The flanging is a three-dimensional...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: in the production process of the existing steel plate box cover, the corner 1 often has a part protruding from the upper edge of the box cover after the corner is turned up and pressed, resulting in the edge of the box cover not being correct. Flat, poor stability, and sharp raised parts, which may cause harm to the human body and have potential safety hazards; moreover, the production of steel plate box covers requires four processes, and the process is relatively complicated and cumbersome
