[0049] The working process of the present utility model: In the previous process, the electric heating tubes 30 to be processed are fed to the clamping die 8. Five electric heating tubes 30 can be cut at a time. The clamping die cylinder 807 is started to drive the pressing plate 809 to press down. The pressing plate 809 can cooperate with the clamping block 801 and the guiding plate 802 to clamp the electric heating tubes 30 tightly, and perform clamping and preliminary positioning on the electric heating tubes 30. Subsequently, the positioning cylinder 206 is started to make the positioning block 201 gradually approach the electric heating tubes 30 until all five electric heating tubes 30 extend into the positioning holes 210 for positioning. With the help of an external feeding mechanism, the positioned electric heating tubes 30 are transferred to the clamping die 8 close to the cutting rod component 1. The push-pull cylinder 111 is started to make the guiding block 106 gradually approach the electric heating tubes 30 until all five electric heating tubes 30 extend into the guiding holes 119 for positioning. Then the cutting knife cylinder 110 is started to drive the cutting knife 109 (upper mounting plate 114) to move downward to cut the electric heating tubes 30. The waste generated by cutting enters the blanking groove 118 along the inclined surface and is discharged from the waste discharging groove 501 out of the table board 5.
