The piston rod of the first hydraulic cylinder 7 is connected to the press-cutting knife 8. A pressure block 9 is also connected to the base body 5 for lifting. The pressure block 9 cooperates with the action of the press-cutting knife 8 to clamp the workpiece 3 to prevent the workpiece 3 from being displaced when the press-cutting knife 8 falls.

[0026] The upper end of the front face of the pressing cutter 8 is vertically arranged with the workbench 1, the lower end of the front face of the pressing cutter 8 is an inclined surface that shrinks inward, the rear end face of the pressing cutter 8 is an inclined surface, and the blade of the pressing cutter 8 is arranged along the inclination angle of the knife seat 6.

[0027] The working principle of the above structure is: the workpiece 3 is pre-processed with an inclined surface corresponding to the angle of the pressing cutter 8 at one end facing the pressing and cutting forming mechanism; the pushing mechanism 2 intermittently pushes the workpiece 3 toward the pressing and cutting forming mechanism. After the workpiece 3 is under the pressing cutter 8, the pressing block 9 moves downward, and then the pressing cutter 8 moves downward to press and cut the workpiece 3 (without completely cutting off the workpiece 3). The end of the workpiece 3 that is pressed and cut stands up along the angle of the front end face of the pressing cutter 8 to form a fin; thus, the pushing mechanism 2, the pressing block 9 and the pressing cutter 8 cooperate to continuously process the workpiece 3. After the processing is completed, the fin part is cut off from the workpiece 3 by the cutting mechanism.

[0028] The beneficial effects of the above structure are: simple structure, low manufacturing cost, small space occupation, and the ability to quickly process and shape small aluminum workpieces constituting the fins inside the oil cooler, and to perform continuous processing.
