The ratio of the distance between the vertical dimension of upper end-face edge distance second bottom surface on described groove inclined-plane and the top of the second vertical plane and the first bottom surface is 1/2, when making the 4th bending segment after bending and the 7th bending segment parallel, the 5th bending segment and the 6th bending segment are symmetrical along horizontal center line.
Acute angle between described groove inclined-plane and the second bottom surface is 45 °, and the angle between pentagonal 4th bending segment and the 5th bending segment after bending forming is 90 °.
A kind of bending method of pentagon rack enclosure, it is characterised in that: comprise the following steps:
Step one, the sheet material of selection suitable length, make marks at the first bending segment on sheet material；
Step 2, by the upper end being placed in the first stamped groove of sheet material, mark described in step one is placed in the tip edge of the first vertical plane, utilizes the first punch die to carry out punching press, form the first bending segment, the second bending segment and the 3rd bending segment；
Step 3, being bent downwards by the sheet material of the 3rd bending segment, form the 4th bending segment, described 4th bending segment is fitted on the upper surface of the first parallels；
Step 4, for axis, the sheet material of bending is rotated 180 ° with horizontal line being placed in the second stamped groove, the 3rd vertical plane of the 3rd bending segment and the second stamped groove is fitted；
Step 5, by the second punch die along the 3rd vertically towards the second direction, base punching press, form the 5th bending segment；
Step 6, the 5th bending segment is bent to the second side of the second punch die and ramp direction, form the 6th bending segment and the 7th bending segment；
Step 7, make the 6th bending segment and the 7th bending segment for entirety, with bending place between the 5th bending segment and the 6th bending segment for axle by the 7th bending segment punching press at the second bending segment, make the seven or six bending segment fit with the second bending segment, complete to bend.
The present invention compared with prior art has the effect that first Development and design two set particular manufacturing crafts, former technique is bent the first bending segment, second bending segment, 3rd bending segment, the process simplification of the 4th bending segment and the 5th bending segment is twice mould punching and the most simply bends, then through twice simple bending forming, whole process has only to twice punch forming and three simple bendings, and be not required to dismantle mould, just complete original " roll over six times curved, dismantle a mould " task, qualification rate, production efficiency is all greatly improved, so production in enormous quantities of the rack for having this closing pentagonal configuration provides technology ensuring.
