摘要： PURPOSE:To set a material to be treated at suitable position and to prevent the development of defect caused by unevenness of heat-treatment by constituting a carrying means of a quenching apparatus by a carrying shaft having positioning means fixing the range of reciprocation and a holding member arranged to the carrying shaft. CONSTITUTION:In a high frequency plug quenching apparatus, the carrying means 5 is formed by the carrying shaft 6 and the holding member 7, 7 arranged to the carrying shaft 6. The carrying shaft 6 is arranged along a carrying line and reciprocately moved by a cylinder 9. The range of reciprocation is fixed by using a positioning shaft 13 and the rod 11 with liftable step. The holding member 7 is composed of one pair of the supporting tools 14, 14' and fitted to the carrying shaft 6 as rotatable and also by forming the recessed part at one side 14 of the supporting tool, the treating material is held. By this method, the carried treating material can be set at the position, accurately coinciding with center of the furnace or center of the high frequency plug, and the good quenching can be executed.

CONSTITUTION:A carburized member 1 to be treated is put in the heating coil 2 of a high frequency tempering apparatus, and high frequency current is supplied to the coil 2 to heat chiefly the part 3 of the member 1 to be treated. At this time, the member 1 is heated at high output to a temp. required to carry out high frequency tempering, that is, 600 deg.C- the transformation point, and it is heated at low output. By the two-step heating the member 1 is held at said temp. for a sufficient time.

摘要： PURPOSE:To discover melting abnormality in an early period by measuring the supply voltage value from a TIG power source and judging the melting abnormality when the value exceeds a prescribed upper limit value or lower limit value. CONSTITUTION:The remelting treatment of a cam 4 is executed by moving a TIG torch 3 having the TIG power source 1 and a tungsten electrode 2 back and forth in an arrow A direction and displacing the torch to follow up at prescribed intervals in an arrow B direction. A cam shaft 5 rotates the cam 4 and a position detector 6 detects the position of the cam 4. An ammeter 7 and a voltmeter 8 are mounted to the TIG power source 1 and the voltmeter 8 can detect the upper limit value and the lower limit value. A melting shear droop 13 is generated on the end face of the cam 4 when the central point of the forward and backward movements of the electrode 2 deviates from a center line 11. The remelting region diminishes when the spacing R between the electrode 2 and the surface 10 of the cam 4 is shorter than the prescribed distance. The voltage of this time is lower than the lower limit value. The defect of the remelting treatment is discovered by measuring the voltage.
