Below with regard to the thermal treatment unit of cylindrical workpiece of the present invention, describe with reference to Fig. 1～Fig. 3.
The thermal treatment unit 10 of cylindrical workpiece of the present invention, as Fig. 1～shown in Figure 2, the thermal treatment unit of being carried by horizontal type (Fig. 4 is the thermal treatment unit that longitudinal type is carried) constitutes, have to horizontal extension, around two cylinders 11,12 of cylinder axis rotation, cylindrical workpiece 13 is transferred on these two cylinders 11,12.Cylindrical workpiece 13 can be a plurality of, carried continuously to the workpiece spindle direction.The speed of rotation of two cylinders 11,12 can be controlled.
As shown in Figure 3, the axial shape of cylinder of each cylinder 11,12 (outer shape of the cylinder during the cylinder side-looking) is respectively the circular shape of (it is crooked that the vertical central part of cylinder more is positioned at center axis ground than the straight line that connects the vertical both ends of cylinder) concavity.And, each cylinder 11,12, the diameter of workpiece outlet side end less than the diameter of workpiece inlet side end.The radius R of circular arc is about 10000～200000mm.Fig. 3 is the outer shape of the cylinder 11,12 of exaggeration expression.Because the side of cylinder 11,12 is at axial circular shape, therefore, cylinder 11,12 carries out line with workpiece 13 and contacts.If the side of cylinder 11,12 is at axial rectilinear form, there have on the angle of inclination because of cylinder 11,12 to be poor, contacts so cylinder 11,12 becomes at direction of principal axis and workpiece, owing to form circular shape, cylinder 11,12 becomes line with workpiece 13 and contacts.
At least one of two cylinders 11,12 tilts downwards from level attitude towards the workpiece outlet side from the workpiece inlet side, and above-mentioned two cylinders 11,12 are different from the angle of inclination that level begins, and the difference at its angle of inclination is in the scope of 0.5～5 degree.The big cylinder in angle of inclination plays a role as " conveying cylinder " of conveying workpieces, and the little cylinder in angle of inclination plays a role as " swing roller " of rotational workpieces.Owing to be conveying workpieces 13 on two cylinders 11,12 that the angle of inclination difference is arranged, therefore, can center on cylinder axis rotational workpieces 13 on one side, on one side on direction of principal axis, towards the direction conveying workpieces of cylinder decline.
Two cylinders 11,12, the diameter of cylinder of its workpiece outlet side is less than the diameter of cylinder of workpiece inlet side.The linear velocity of the cylinder that diameter is little is low, and the workpiece transfer rate is also low.Because the workpiece outlet side is lower than the workpiece transfer rate of workpiece inlet side, therefore continuously during conveying workpieces 13, workpiece 13 is not separated to each other, under the end state of contact of workpiece 13, conveying workpieces 13 continuously.
