Title: Shape steel rail and work hardening method thereof
Inventor: KAMIYA KAZUJI
IPC: B66F9/08
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To restrain compressive plastic deformation at directly rolling rollers at heavy load by providing work hardened layers compressively worked by bearing pressure of specific times yield strength of the material forming a shape steel rail on the roller rolling surfaces. SOLUTION: Flange parts 12 respectively perpendicularly bent on both side ends of a shape steel rail 11 are pinched between working rollers 14, 15, compressive rolling is worked on the inside faces and the outside faces of the flange parts 12 by means of the working rollers 14, 15, and hence work hardened layers 13 are formed. In this case, bearing pressure applied to the inside faces and the outside faces of the flange parts 12 is set in the range of 1.5-3 times yield strength of the material of the shape steel rail 11 by adding a load to the working rollers 14, 15.  By executing such compressive roller working, even if bearing pressure of estimated impact load is loaded from the rollers of a carriage on the work hardened layers 13 formed by plastically deforming the inside faces and the outside faces of the flange parts 12, almost no recessed part can be formed on the work hardened layer 13.

IPC: G01L5/00
Filed: 1985-02-28
Abstract: PURPOSE:To eliminate a pressure sensor by connecting a current detecting resistor in series with a motor, and obtaining hydraulic pressure of a load from a voltage between the terminals. CONSTITUTION:A current from a battery 10 is flowed through an e terminal of a relay 3, a make contact 8, an f terminal, a current detecting resistor 5 and a motor 4. A voltage V0 across the resistor 5 is input through leads 6, 7 for monitoring a motor current to a controller 1. If the voltage V0 is V1 or lower, the controller 1 closes the relay 3 to drive the motor 4. When the motor 4 is moved, hydraulic pressure rises. When the voltage V0 exceeds V2, the controller 1 opens the relay 3 to stop the motor 4.
