Upper end is inserted in spring groove and forms bilateral symmetry, this keeps the stress of module more uniform.
Further, it is adjustable for positioning the positioning of workpiece to be respectively provided with several positions for the top side wall on lower die cavity both sides
Block, workpiece can be positioned after being put by locating piece.
Further, the upper mold and lower die are string configuration, by least one section of upper mold and at least one section of lower die group
At entire mold, longer workpiece can then be carried out in this way by lengthening mold according to actual needs by mold sections
Bending and molding.
It is first put the workpiece in module before molding, upper mold is molded downwardly against rear and lower die under workpiece, tolerance clearance root
Given according to the tolerance of product requirement, workpiece is the spring in upper mold and lower die intermediary form, upper mold and lower die bearing up-down force at this time
It compresses and shrinks, upper mold resets recoil of spring after release, and module is returned to original state.
The utility model is not wide according to numerical control bender suitable for foldable forming width, length is longer using being bent into pattern
Workpiece directly once completes bending and forming in conjunction with the forming principle of stamping die on numerical control bender, and size can be completely secured
The flatness of tolerance and product, and can it is different according to the length specification of product and using segmentation be made into several sections single mode splicing and
It is formed at mold, therefore is highly suitable for forming the product of fine and closely woven hole loudspeaker baffle and similar structures.
