Abstract
The present invention discloses a swaging die holder for the flexible shaft operations. In the preferred embodiment, the swaging die holder comprises of an elliptical die holder slot, a stress relief slot, a radius curve, a recess and an insert. The die holder slot at top of the die holder allows each die holder to mount to the machine. The insert is adapted through the recess at the bottom of each die holder and designed to produce the different output profiles at the end of the flexible shaft. The insert is made of HSS material with cobalt content to achieve optimal life. The insert is further re-grinded or re-sharpened for same or other profile applications of the flexible shaft.
Claims10
A swaging die holder comprises:
- a. at-least one die holder slot (102a, 102b, 102c and 102d) at a top of the die holder (101a, 101b, 101c and 101d), wherein the die holder slot (102a, 102b, 102c and 102d) allows the die holder (101a, 101b, 101c and 101d) to mount to a machine;
- b. a stress relief slot (103) on the top of the die holder (101a, 101b, 101c and 101d) on the periphery therein, wherein the stress relief slot (103) uniformly distributes a stress concentration and thereby reducing a chance of a die holder (101a, 101b, 101c and 101d) breakage due to an impact forces, during a swaging operations;
- c. a radius curve (104) at a corner of the die holder (101a, 101b, 101c and 101d) avoids a clashing between the die holders (101a, 101b, 101c and 101d) in a closed condition, during a sliding operation of a flexible shaft;
- d. a recess (105) extended longitudinally throughout at a bottom of the die holder (101a, 101b, 101c and 101d);
- and
- e. an insert (106), wherein the insert (106) is inserted through the recess (105) at a bottom of each die holder (101a, 101b, 101c and 101d), wherein the insert (105) at the bottom is designed to produce one or more output shapes at an end of a flexible shaft (107).
