Working 吋, tightening the adjusting screw 503 to make the driven shaft fixing block 202 and the limiting washer 108 close to each other. When the feeding finger pulls the feeding belt forward, the upper and lower hobbings will rotate, and the rolling shearing force is used to cut the slab. Since the shear length of this method is completely dependent on the feed length, the joints in the old structure and the single and double jump burrs can be completely eliminated.

[0042] The power source of such a hobbing structure is classified into two according to the size of the mold and the number of feed fingers. One is that when the number of feed fingers is sufficient, the power can be completely provided by the feed fingers, the part gear plate 401, the gear shaft 402, the second bearing 502, the drive gear 914, the key 915, the first intermediate gear 916, and the second intermediate The gear 917 does not need to be installed; the other is that when the number of feeding fingers is small, the pulling of the feeding finger alone may cause the fin hole to be deformed. Therefore, an auxiliary motor needs to be additionally installed. The running state of the motor should be synchronized with the feeding, the motor and the active The shafts 106 are connected to each other, and the driven shaft 201 is synchronously rotated by the driving gear 914, the first intermediate gear 916 and the second intermediate gear 91 7 .
