Abstract
A grooving device comprises a hydraulic cylinder, a cutter, an upper pressure plate, a spring, an upper template, a lower template, a guide shaft and the like; the method is characterized in that: the cutter is fixed on the piston, the upper and lower dies are respectively fixed on the cylinder body and the piston of the gas-liquid pressure cylinder, when the upper cavity of the pressure cylinder is filled with hydraulic oil, the upper and lower dies can automatically move oppositely and press the aluminum pipe by taking the axis of the aluminum pipe as the center, and when the aluminum pipe is clamped, the upper and lower dies continue to move downwards, thereby completing the grooving process without a core die.
Description
Technical field
The present invention is that one is applied on all kinds of copper pipe grooving production lines, utilizes hydraulic cylinder, without core, just can on all kinds of copper pipes, process the groover of rectangle hole slot.
Background technology
In producing and living, all will use in large quantities various refrigeration plants, wherein various copper pipes, for increasing heat radiation area all will have a large amount of rectangle hole slots, are beneficial to flowing of fluid. How employing completes with the pressing of composite core rod generally on hydrops copper pipe, to offer this this process of rectangle hole slot, not only inefficiency, and because stamping press is larger, easily make copper pipe distortion, make the difficult guarantee of quality. For solving this class problem, the present invention is directed at copper pipe and open rectangle hole slot, a kind of copper pipe spindle-less groover is provided.
Summary of the invention
At present, for offer rectangle hole slot on copper pipe, adopt completes with the pressing of composite core rod more. Not only inefficiency, and because stamping press is larger, easily make copper pipe distortion, make quality be difficult for the problem ensureing. The invention provides a kind of air conditioner copper pipe suspension cutter grooving device being formed by liquid pressurized cylinder, bolt, mobile briquetting, spring, upper die and lower die, three sword cutting knifes etc. Piston by single liquid pressurized cylinder moves down, and drives mobile briquetting also to move down, and promotes patrix by spring and be pressed on copper pipe top, and piston continues to promote after three sword cutting knifes move down and touch copper pipe to keep motionless. Then the pneumohydraulic pressure-cylinder being fixed together with counterdie drives counterdie to move up under the effect of oil pressure, and pipe clamp is tight. Oil pressure continuation effect, piston continuation promotion three sword cutting knifes move down, and complete the processing of rectangle hole slot.
Technical scheme
On copper pipe, process rectangle hole slot, for preventing that flush shear force from deforming compared with ambassador's copper pipe, copper pipe is die-cut with carrying out after mold cramping. As only carried out Punching Technology in copper pipe one side, clamping mold can be designed to that one is semifixed and second half is movably. But in the time will carrying out Punching Technology respectively in copper pipe both sides, two parts clamping mold for can and copper pipe fit tightly and just all will be designed to movably. Concrete technical scheme is the Punching Technology for a rectangle hole slot, only adopts a pneumohydraulic pressure-cylinder. Make the piston of pneumohydraulic pressure-cylinder promote patrix by spring and be pressed on copper pipe top, and piston is connected firmly together with three sword cutting knifes; Pneumohydraulic pressure-cylinder connects firmly together with counterdie. Effect lower piston at oil pressure stretches out downwards from pneumohydraulic pressure-cylinder, promotes patrix and three sword cutting knifes and moves down, and will move up with pneumohydraulic pressure-cylinder under the effect of oil pressure simultaneously, and the counterdie together with it connects firmly also will move up. The result of upper and lower mould move toward one another has just clamped copper pipe. Oil pressure continuation effect, piston has also moved down continuation promotion three sword cutting knifes the processing of rectangle hole slot.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structure principle chart of the present invention.
1. liquid pressurized cylinder, 2. pressurized cylinder epicoele, 3. pressurized cylinder piston bar, 4. housing, 5. cutting knife, 6. pressing plate, 7. spring, 8. patrix, 9. copper pipe, 10. counterdie, 11. curve cutoff edges, 12. straight line cutoff edges, 13. rectangular channels, 14. axis of guides, 15. attachment bolts.
Detailed description of the invention
Various copper pipes in refrigeration plant, are increasing heat radiation area, all will have a large amount of rectangle hole slots so that fluid passage to be installed. This device adopts copper pipe (9) level is fixed, and housing (4), under the driving of servo-drive system, moves along copper pipe (9) axis direction, carries out the arrangement of stepping grooving. As shown in Figure 1, on copper pipe (9), process rectangle hole slot (13), for preventing that flush shear force from deform copper pipe (9), after copper pipe (9) being clamped with counterdie (10) and patrix (8), carry out die-cut. Because copper pipe (9) is softer and longer, therefore when copper pipe (9) level is fixed, its horizontal level is difficult to accurately ensure. Counterdie (10) and patrix (8) are all designed to movably, make it in grooving process, can automatically float with the position of copper pipe (9).
Detailed description of the invention is, adopt the liquid pressurized cylinder (1) of Floating connection, in the time that pressurized cylinder epicoele (2) is filled with hydraulic oil, pressurized cylinder piston bar (3) together promotes pressing plate (6) with the cutting knife connecting firmly on it (5) and moves downward, when moving downward, passes through by pressing plate (6) spring (7), promote patrix (8) and together move, and make patrix (8) press to copper pipe (9). And simultaneously, be filled with pressurized cylinder epicoele (2) hydraulic oil also the cylinder body that promotes pneumohydraulic pressure-cylinder (1) to be moved upward, the cylinder body of pneumohydraulic pressure-cylinder (1) connects firmly together by the same axis of guide of attachment bolt (15) (14). In the time that the axis of guide (14) moves upward in company with the cylinder body of pneumohydraulic pressure-cylinder (1), also drive counterdie (10) together to move upward simultaneously, press to copper pipe (9). When patrix (8) and counterdie (10) move toward one another, common clamping after copper pipe (9), while being filled with the hydraulic oil of pressurized cylinder epicoele (2), continuing to promote pressurized cylinder piston bar (3) moves downward with the cutting knife connecting firmly on it (5), at this moment, it is upper motionless that patrix (8) has been pressed on copper pipe (9), and spring (7) continues compressed, cutting knife (5) is copper pipe (9) tangentially, completes the technical process of grooving.
For making cutting knife (5) cut out rectangular channel on copper pipe (9) under as far as possible little pressure, the blade of cutting knife (5) does not adopt the form of conventional straight line cutoff edge (12), and adopted the form of curve cutoff edge (11), obtain more sharp-pointed point of a knife with it.
Claims (1)
1. a groover, is made up of liquid pressurized cylinder, cutting knife, top board, spring, cope match-plate pattern, lower bolster, the axis of guide etc.; It is characterized in that: cutting knife is fixed on piston, upper and lower mould is separately fixed on the cylinder body and piston of pneumohydraulic pressure-cylinder, in the time that pressurized cylinder epicoele is filled with hydraulic oil, can automatically make upper and lower mould move toward one another centered by aluminum pipe axis press to aluminum pipe, when clamping after aluminum pipe, continue to move downward, complete the technics of slot process without core.
