Sheet metal process ---- bending. Stamping. Benchwork technology
The rapid development of the machinery manufacturing industry also puts
forward higher and higher requirements for the technical level of the first-line
employees. Engaged in the present technician, not only the actual operation
needs to be skilled, but also to master the basic theory and relevant knowledge,
with the ability to analyze and solve problems and good at innovation, in order
to meet the needs of customers, in folding bed, stamping, lockwork constantly
changing to improve its processing methods and process system principle and
application, Inefficient processing method and equipment to expand the use of
such knowledge as a whole, with modern equipment with practice, the content of
the pursuit of further improve the level of operation and the production
efficiency, and strive to original design considering the primary producers of
requirements with respect to the practical difficulties and solve problems,
especially put forward the solution to the problem, and work out appropriate
product requirements, item by item list for discussion, And can be in line with
practical and effective, have the corresponding help.
Bending forming - bending forming of the working principle is the upper and
lower die are fixed on the upper and lower table of the folding bed, the use of
servo motor transmission hydraulic drive table relative movement, combined with
the shape of the upper and lower die, so as to achieve the bending of the plate.
The bending forming accuracy of each fold can reach 0.1mm.
Common bending forming: usually we can complete with folding bed forming 90
degrees bending, non 90 degrees bending, pressing edge (including less than the
thickness of the gap), section difference.
When bending two adjacent edges, if there is a wrapping relationship between
each other, the process hole should be considered in the bending edge corner
(the diameter of the process hole is not less than the thickness of the plate),
and a reasonable gap should be set aside according to the thickness of the plate
(0.15 times the thickness of the plate).
The minimum distance between the hole and the edge of the bending parts,
usually, we take down the mold slot width of 1/2+0.5, in the design of sheet
metal parts, as far as possible to avoid the occurrence of a hem or hole
distance from the edge of the distance is less than the size requirements
