Abstract
Description
The present invention relates to a safety door frame cover processing method using a forming machine that can be produced in large quantities by extruding a metal disc through the forming machine. In particular, the cross-sectional structure of the upper and lower extrusion rolls formed in the forming machine is optimally selected to form bent portions on the left and right sides of the metal plate passing through the upper and lower extrusion rolls, and the desired bent portions are completed through the fastest single extrusion rolls. The present invention relates to a safety door frame cover processing method using a forming machine to produce a large amount of cover.
In general, a forming machine is a machine for bending a metal plate through pressing, extruding and pressing to produce a sheet having a desired bent portion.
Therefore, most metal sheets have been produced and used in large quantities through these forming machines. By the way, in the case of such a forming machine, there is provided a vertical extrusion roll that rotates at the same rotational speed from the top and bottom, there is a big difference in the speed of its production depending on how to form the cross-sectional shape of the vertical extrusion roll. That is, when the unnecessary extrusion process is put in, the time and cost of manufacturing are generated, and mass production is impossible.
Therefore, it was most effective to optimally form the shape of the outer cross section of the extrusion roll and to allow the metal plate passing therethrough to be continuously bent to have a desired bent portion. By the way, in the conventional case, if you want to produce a cross section, such as the safety door frame cover produced in the present invention, it could be completed only through about 9 to 15 extrusion rolls. The structure of such a conventional extrusion roll was a method requiring an improvement that unnecessary effort is put into improving the time and cost of product production.
The present invention is to provide a safety door frame cover processing method using a forming machine that can be produced in a large amount by extruding a metal disc through the forming machine.
In detail, the cross-sectional structure of the upper and lower extrusion rolls formed in the forming machine is optimally selected to form bent portions on the left and right sides of the metal plate passing through the upper and lower extrusion rolls, and the desired bent portions are completed through the fastest single extrusion roll. To provide a safety door frame cover processing method using a forming machine to be able to produce a large amount of the frame cover.
Safety door frame cover method using a forming machine according to the present invention, the first step: supplying the
In addition, according to the safety door frame cover processing method using the forming machine of the present invention, a pair of
According to the present invention, there is an advantage that productivity can be improved because a structural combination of a simple extrusion roll can be achieved to yield more output in less time.
In addition, according to the present invention, it is possible to reduce the cost because it is possible to produce more of the frame cover of the safety door that was conventionally produced through a small number of extrusion rolls.
In addition, according to the present invention it is possible to produce higher productivity with only a small process, it is possible to reduce the installation cost because it can arrange a small number of extrusion rolls.
