The left and right sides of the lower adjustment block are in close contact with the adjustment seat and the upper adjustment block respectively under the action of the mold spring to form a contact surface. Multiple oil grooves are formed on the contact surface.

7. A high-efficiency, high-speed tubular heat sink processing equipment according to claim 1 or 5, characterized in that, The shovel component includes a shovel drive, a shovel base, and a connecting rod assembly. The output end of the shovel drive is coaxially mounted with a crankshaft. The crankshaft drives the sliding shovel assembly to perform linear reciprocating motion along the length of the shovel base via the connecting rod assembly. The sliding shovel assembly includes a sliding shovel push plate. The sliding shovel push plate is equipped with a material support frame and a knife holder. The knife holder is detachably equipped with a clamping body whose blade edge faces the same direction as the workpiece's travel.

8. The high-efficiency, high-speed tubular heat sink processing equipment according to claim 7, characterized in that, The eccentric clamping plate includes two main plates in the same vertical plane. The distance between the two main plates is not less than the linear reciprocating stroke of the blade holder. The connecting rod assembly includes a double-ended screw. One end of the double-ended screw is rotatably sleeved on the crankshaft, and the other end is rotatably sleeved on the connecting shaft. Both ends of the connecting shaft are mounted on the sliding blade push plate through connecting arms. Several guide components are provided between the sliding blade push plate and the blade base. The guide components include guide rails and guide sliders.

9. The high-efficiency, high-speed tubular heat sink processing equipment according to claim 1, characterized in that, The waste collection device includes a waste box, several waste drawers, and two feed hoppers. Waste inlets are provided on the machine body corresponding to two shovel components. The two feed hoppers are located below the corresponding waste inlets. The several waste drawers are slidably connected to the waste box. An oiling device is also provided on the machine body. The oiling device includes a double-sided oiling mechanism and a single-sided oiling mechanism. The double-sided oiling mechanism is located between the continuous feeding device and the single-sided shovel mechanism. The single-sided oiling mechanism is located between the two sets of single-sided shovel mechanisms.

10. The high-efficiency, high-speed tubular heat sink processing equipment according to claim 9, characterized in that, The double-sided oiling mechanism includes an upper support and a lower support mounted on a continuous feeding device. A rotatable fixed roller and a felt roller are mounted between the upper support and the lower support. The relative distance between the felt roller and the fixed roller can be adjusted by an adjusting component. The single-sided oiling mechanism includes a roller bracket mounted on the machine body. An upper support, a lower support, and an oil collection box are mounted on the roller bracket. A rotatable felt roller is mounted between the upper support and the lower support. The oil collection box is located below the felt roller and is connected to the waste bin via a pipeline.
