In addition, still be equipped with the shower nozzle on the processing head base, inside can also install oil pipe, and the shower nozzle is connected to oil pipe one end and is used for spraying the heat that cooling oil produced in order to eliminate the course of working to the metal flat surface in the course of working, and cooling oil directly falls into in the oil box, and the oil box realization circulation can still be connected through the circulating pump to the oil pipe other end.
The large dovetail groove sliding table 3, the small dovetail groove sliding table 4, the three-phase alternating current motor 5, the cycloidal pin gear speed reducer 6, the electric cylinder 8, the gear 12, the gear frame 7, the gear shaft 13, the connecting rod connecting piece 14, the roller shaft 15, the limiting roller 16, the backing plate 17, the chain wheel coupling 18 and the servo driver 19 form a driving unit and a runway-shaped reciprocating unit; the three-phase alternating current motor 5 is arranged on the bracket, the output shaft of the motor is fixed with a gear shaft 13, a gear 12 is assembled on the gear shaft 13, and the motor drives the gear to rotate; the bottom surface of the big dovetail groove sliding table 3 is arranged on the bracket, the bottom surface of the small dovetail groove sliding table 4 is fixed on the sliding surface of the big dovetail groove sliding table 3, the sliding directions of the two sliding tables are vertical, the runway-shaped internal tooth frame 7 is fixed on a base plate 17 on the sliding surface of the small dovetail groove sliding table 3, the runway-shaped internal tooth frame is in a shape of a runway formed by two sections of semicircular gear rings and two sections of linear racks parallel to the sliding direction of the big dovetail groove sliding table 3, and the gear shaft 13 extends into the runway-shaped internal tooth frame 7 to enable the gear; the gear shaft 13 is also provided with a connecting rod connecting piece 14 which can only rotate relatively, a roller shaft 15 is fixed on the connecting rod connecting piece 14, the lower end of the roller shaft 15 is provided with a limiting roller 16, the gear 12 is meshed with the runway-shaped inner gear ring 7, and simultaneously the limiting roller 16 is attached to the outer ring of the runway-shaped inner gear ring 7.
Referring to fig. 2 and 4, since the gear 12 is mounted on the gear shaft 13, the three-phase ac motor 5 rotates the gear shaft 13 via the cycloidal pin gear reducer 6, and thus rotates the gear 12. When the gear 12 is engaged with the rack segment of the toothed frame 7, the transmission device drives the metal flat plate 10 to do uniform linear motion. Meanwhile, as the gear frame 7 has a gear ring section, the motion state can be switched in a forward and reverse uniform linear motion state as long as the gear 12 rotates and is meshed with the gear frame 7 in one motion period. And a base plate 17, a small dovetail groove sliding table 4 and a large dovetail groove sliding table 3 are arranged below the gear frame 7. Therefore, when the gear 12 is meshed with the gear ring section of the gear frame 7, the small dovetail groove sliding table 4 and the large dovetail groove sliding table 3 both do uniform linear motion; when the gear 12 is meshed with the rack section of the gear frame 7, the large dovetail groove sliding table 4 moves linearly at a constant speed, and the small dovetail groove sliding table does not move.
The processing head is fed back and forth by combining an electric cylinder, namely a transverse feeding device, and a gradient nano structure can be formed on the surface of the metal flat plate after the two motions are superposed.
The electric cylinder can realize the forward and backward feeding of the rolling processing device through an electric control part (a possible control method is shown in fig. 5, but the electric cylinder transverse feeding control is not limited to the following method).
Referring to fig. 5, before machining, a button a24 is pressed to change the level of a certain port of the single chip 22, and the single chip 22 receives the signal and then sends a control command to the servo driver 19. After receiving a control instruction of the single chip microcomputer 22, the servo driver 19 drives the electric cylinder 8 through the power cable, and finally drives the machining head 1 to feed. After the processing of one pass is finished, the buzzer 23 will automatically send out three-sound drop to prompt the completion of the processing. When a pause key on the operation panel of the down converter is pressed, the three-phase alternating current motor 5 stops rotating, and the electric cylinder 8 automatically stops feeding. Before the next process is performed, the button a24 is pressed again, and the electric cylinder 8 is fed in the opposite direction to the previous process, and then the rolling process is continued on the flat metal plate 10.
Further reference is made to fig. 3. The position of the processing head base 9 in the apparatus is fixed relative to the metal plate 10. Because the motion of the transmission device has periodicity, the metal flat plate 10 is driven to do periodic reciprocating constant-speed runway-shaped motion in the machining process. In one working pass, the working head 1 is in close contact with and rolls the metal plate 10 on both sides under the action of air pressure, and the rolling force is the same and is kept constant. In a movement period, the rolling treatment of the upper processing head 1 and the lower processing head 1 generates an indentation on the two sides of the metal flat plate. When the transmission device returns to the motion starting point, the electric cylinder 8 pushes the upper machining head 1 and the lower machining head 1 to feed forwards, so that the machining head 1 generates a minimum displacement. Then the transmission device drives the metal flat plate 10 to do reciprocating linear motion at a constant speed again, so that the surface of the metal flat plate 10 generates an indentation and is partially overlapped with the previous indentation. The overlapping of the plurality of indentations creates a roll-formed area on the surface of the flat metal sheet 10. The pressure is adjusted by the gas cylinder to increase the machining pressure before the next pass is performed, and then the above process is repeated, and the machining head 1 is fed backward in the machining process. The process requires multiple passes of the metal plate and maintains a uniform increase in the processing pressure in each pass, with opposite feed directions of the processing heads 1 in adjacent passes.
