Abstract
Abstract Disclosed herein is a process for clinching a wire rope on a buckle base, which comprises the following consecutive steps: subjecting a starting anchor block material and the wire rope in combination to a first clinching operation to obtain a preformed anchor block bearing steps therein; and subjecting the preformed anchor block and the buckle base in combination to a second clinching operation to clinch the resultant anchor block on the buckle base, which second clinching operation is applied in a direction different from the first clinching operation. Owing to the first and second clinching operations carried out in directions different from each other, the resulting stresses are scattered and the anchor block is thus protected from being overstressed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
106 words
A process for clinching a wire rope on a buckle base, which process comprises the following consecutive steps: subjecting a starting anchor block metal sleeve and the wire rope in combination to a first clinching plastic deforming operation to form a preformed anchor block bearing steps extending up radially outwardly thereon; and subjecting the preformed anchor block and the buckle base in combination to a second clinching plastic deforming operation to clinch the resultant anchor block on the buckle base, which second clinching operation is applied in a direction at an angle or angles substantially different from the first clinching operation to scatter the resulting stresses.
Claim 2
Dependent Claim
106 words
A process for clinching a wire rope on a buckle base, which process comprises the following consecutive steps: subjecting a starting anchor block metal sleeve and the wire rope in combination to a first clinching plastic deforming operation to form a preformed anchor block bearing steps extending up radially outwardly thereon; and subjecting the preformed anchor block and the buckle base in combination to a second clinching plastic deforming operation to clinch the resultant anchor block on the buckle base, which second clinching operation is applied in a direction at an angle or angles substantially different from the first clinching operation to scatter the resulting stresses.
Claim 3
Dependent Claim
23 words
The process as claimed in claim 1, wherein the second clinching operation is applied in a direction perpendicular to the first clinching operation.
Claim 4
Dependent Claim
104 words
A process for clinching a wire rope on a buckle base, which process comprises the following consecutive steps: fixing a starting anchor block metal sleeve on the wire; subjecting the starting anchor block material to a first clinching operation to form a preformed anchor block bearing steps extending radially outwardly thereon; and subjecting the preformed anchor block and the buckle base in combination to a second clinching operation to clinch the resultant anchor block on the buckle base, which second clinching operation is applied in a direction at an angle or angles substantially different from the first clinching operation to scatter the resulting stresses.
Claim 5
Dependent Claim
104 words
A process for clinching a wire rope on a buckle base, which process comprises the following consecutive steps: fixing a starting anchor block metal sleeve on the wire; subjecting the starting anchor block material to a first clinching operation to form a preformed anchor block bearing steps extending radially outwardly thereon; and subjecting the preformed anchor block and the buckle base in combination to a second clinching operation to clinch the resultant anchor block on the buckle base, which second clinching operation is applied in a direction at an angle or angles substantially different from the first clinching operation to scatter the resulting stresses.
Claim 6
Dependent Claim
22 words
The process as claimed in claim 3, wherein the steps are brought into abutment against the lower surface of the buckle base.
