Abstract

A process for the production of heavy industrial hooks consuming minimum material and production time in a cost saving measure with improved quality.
Maximum quality is achieved by having the grain direction following the shape of the hook

Description

SPECIFICATION
Sketch. 2. Identifies the transformation from the original section of the hook to the round section in the entire length. Each hook type has different dimensions for L 1, L2, and L3, L4. and diameter for D 1, D2, and D3 .
Operations; 1,2 identifies the bending of Rl and the initial bending of R2 from sketch No. 1 Operations; 3,4 determine the initial bending which ensures the final bending stage forces the curve in right direction.
OP. 5, forging the round sections to take on a finished form in the sections of the hook. Tools must be inclined 1: 4 as in the finished shape of the hook.
>.
FUNCTION OF THE TOOLS IN OPERATION No 5.
The upper and lower tools inclined to a ratio of 1:4 must be rotated to forge the curve of the hook over its entire length due to the manipulator presses or hammers usually having movement in the right angle to tools of the presses or hammers.
Rotation tools' incline at a ratio of 1:4 make it possible to forge the round sections into a cone shape at the same time as bending the hook in the right dimension.
The rotation of the tools is a manual procedure. The application of the force during forging alters both the shape and dimensions of the round sections of the hook without changing the mass. The inclination of a 1:4 ratio over the length of the surface will cause a different deformation resulting in a different amount of elongation at each section of the hook.
The elongation of the material at point A will be longer than at point B. The mass of the round and final formation are equal, the forged part which will be bent by inclination of the tools will get the exact dimension calculated for the type of hook required.

Claims (3)

1. Tools and technology for production of open die forging single arm hooks comprising support tool, horizontally and vertically rotating tools and the procedure for partial bending and forge round section into final cone shape of the hook.
2. Tools as defined in claim 1, are set up: Vertically rotating tools inclined at a ratio of 1:4, on the upper and lower die tools and horizontally rotating tools on the support tool.
3. A process as defined in claim 1, is how to partial bending rounded forged piece and transform round section in to cone shape at the same time as bending the hook in right dimension.
