Steel plate packaging box cap forming process and cutting special positioning mechanism thereof

Abstract

The invention discloses a steel plate packaging box cap forming process, which comprises the following steps of: positioning a raw material; cutting to obtain a product forming size; trimming, i.e., cutting and trimming an uncut edge to avoid unevenness of the edge; continuously flanging and pressing in the length direction of a cap box; next forming openings at four corners of a steel plate; and finally bending the steel plate along the openings to form a box package. According to the steel plate packaging box cap forming process, two edge parts of the formed cap box are flanged along the openings, so that the tensile strength of the steel plate packaging cap box is enhanced, the planarity of the steel plate packaging cap box is improved, transportation of a steel plate finished plate stack is facilitated, and damage caused by uneven planarity of the box cap in the transportation process of the steel plate stack is avoided; and meanwhile, the two edge parts of the formed cap box are flanged along the openings, so that rejection of box cap machining caused by cracking in the box cap machining process is avoided.

Description

technical field [0001] The invention belongs to the technical field of steel plate packaging, and in particular relates to a forming process of a box cap for steel plate packaging and a special positioning mechanism for material cutting. Background technique [0002] With the rapid development of the economy, the use of cold-rolled steel plates has risen sharply, and cold-rolled products are more and more widely used in household appliances, automobiles, construction, etc. With the intensification of market competition, the cost control of cold-rolled products has become more and more obvious. The important thing is that there are various forms of cold-rolled raw materials, such as steel coils or steel plates. An important means to reduce the cost of cold-rolled materials is to increase the utilization rate of raw materials and ensure that each piece of cold-rolled raw material is not used from production to transportation until it is delivered to the manufacturer.

Problems solved by technology

[0003] The traditional box cap used for steel plate packaging directly makes the steel sheet into a box shape, and the sleeve is changed outside the steel plate to protect the steel plate. However, once the raw material steel plate and the finished plate size are relatively large, The area of ​​the box cap itself will also increase, resulting in an uneven appearance of the square box cap, which will affect the transportation of the entire finished steel plate.
