Title: Form rolling method for screw shank
Inventor: YAMAMOTO MASATOSHI
IPC: H02K15/14
Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To prevent a form-rolling part from extruding a non-machining part by forming an inclined part between a small diameter machining part and a large diameter non-machining part in a base material for a screw shank and forming a tapered part to apply on during the form-rolling in a die for forming a threading groove. SOLUTION: In form-rolling a thread groove in a base material 1 for a screw shank, the thread groove is formed with a die 2 pressed against an inclined part 1c between a machining part 1a and a large-diameter non-machining part 1b as well as against the small-diameter machining part 1a. As a result, with a load at the time of form-rolling actuating centrally on the chuck-side end of the die 2, the part for receiving the load is not only the non-machining part 1a but also the inclined part 1c with a high strength, avoiding bending the machining part 1a as in the conventional case, and enabling the machining of a screw shank with a superior linearity. In addition, the inclined angle αof the tapered part 1b of the die is larger than that β of the inclined part 1c of the base material; therefore extrusion is prevented.

IPC: C08G59/18
Filed: 1981-03-18
Abstract: PURPOSE: A chemically stable water-dispersible resin composition excellent in adhesion, solvent resistance, water resistance, and processability, obtained by irradiating a mixture containing an epoxy resin and a nondissociable hydrophilic group-containing ethylenically unsaturated monomer with electron beams.  
     CONSTITUTION: A mixture consisting mainly of 50W95, pref., 60W90wt% epoxy resin and 5W40wt%, pref., 7W40wt% nondissociable hydrophilic group-containing ethylenically unsaturated monomer is irradiated with electron beams. When the amount of the epoxy resin is below 50wt%, the polymerization of the monomer is slow, whereas when it is above 90wt%, economy is poor. Irradiation with electron beams is carried out at a dose rate of 2/10 2 W30Mrad/sec at a total dose of 0.1W30Mrad. When the dose rate is below 2/10 2 Mrad/sec, dispersion is difficult, whereas when the dose rate is above 30Mrad/sec, the operation of equipments is impossible. When the dose is below 0.1Mrad, the amount of unreacted monomers is large, and a dose larger than 50Mrad is not necessary.
