Multiple through holes are set on the cavity plate piece, it is tight by the bolt and nut that are placed in through hole after some cavity plate pieces are stacked
Gu some cavity plate pieces are a cavity plate entirety.
The segment length of the straight section is 10-20mm, and length is too small to influence formed precision, and length crosses conference and causes mould material
Material is wasted, and increases mold weight.
The resilience segmental arc and straight section the tangent formation springback angle, the angle of the springback angle is 0-5 °.
The utility model has following advantages and effect：Using such scheme, it is convenient to which punch-pin, cavity plate are set respectively
It is not only easy to process into some punch-pin pieces, cavity plate piece, time saving material-saving, and can be easily by some punch-pin pieces processed, recessed
Matrix is installed in the corresponding die shank of bender, groove one by one, and align it is stacked after tightly may be used with bolt and nut, you can
Metal sheet to be processed is put between punch-pin, cavity plate and is bent into required arc-shaped workpiece, can be light without using Large-scale Hoisting machine
Punch-pin, cavity plate are attached on bender by pine, and can increase and decrease punch-pin piece, cavity plate piece quantity according to workpiece to be processed width, simultaneously
The convex of punch-pin piece and cavity plate piece arcs of recesses are divided into the base segmental arc at middle part, the resilience segmental arc of both sides, the straight in outside
Section, and the arc radius of base segmental arc is more than the arc radius of resilience segmental arc, while controlling resilience segmental arc and straight section phase
The spring back angle for cutting place is 0-5 °, it is ensured that after the arc-shaped workpiece resilience processed, will not also change its accurately accurate measurement,
Facilitate subsequent installation.
