Abstract
The utility model relates to an optional feature for expanding the function of the oil hydraulic press, and a rotary rolling head of the utility model can be arranged on the down press type or up-lifting type oil hydraulic press. The pressure oil causes the rotary press head to rotate by a fluid power driving device, and the working feed of oil hydraulic press causes the molding head to press on the work piece to complete the press processing to the work piece in the screw feed. The utility model can cause the pressure efficiency to be raised by 10 to 15 times, and can cause the oil hydraulic press with small tonnage to have the functions of the oil hydraulic press with large tonnage under certain conditions. The utility model has an especially excellent processing effect to circular-shaped and disc-shaped work pieces, etc.
Description
The utility model be on a kind of hydraulic press in order to the optional feature of expanded function, belong to press-down type or go up an auxiliary equipment of act formula hydraulic press.
No matter general hydraulic press is press-down type or go up the act formula, all is the steady vertical feed of pressure head, is pressed on the workpiece with whole plane, and its tonnage is to have designed definitely, and completed state also is constant.
Newly design and manufacture a cover optional feature now, rotation spreading head is attached on the hydraulic press, can expand the function of hydraulic press, mainly is to improve the pressure processing tonnage, makes little tonnage hydraulic press, has the function of big hydraulic press under certain condition; But also the flexibly changing machining state is more conducive to plate-like and ring-type workpiece.
Above purpose is achieved in that as general assembly drawing ［ Fig. 1 ］ can dissect is four part, i.e. spreading head, rotating mechanism, hydraulic unit driver and pedestals.
(1) spreading head ［ 1 ］-［ 8 ］.It has a moulded head ［ 1 ］, its vertical view as shown in Figure 3, the garden column end mills out the pair of parallel limit.The axis of rotation ［ 3 ］ upward view 2 is illustrated in two the parallel scotch ［ 4 ］ of packing in the axis of rotation ［ 3 ］ end slot.Moulded head is pressed in the end slot of the axis of rotation ［ 3 ］ with supported flange ［ 2 ］.Because the effect of scotch, though rotate stressedly, moulded head can not rotate yet.Rotation bearing ［ 5 ］, ［ 7 ］ and locknut ［ 8 ］ are contained in the hole of supporting base ［ 6 ］, and ［ 5 ］ are the bearings that bears pressure.The sloped-end α of supporting seat ［ 6 ］/2 angles matches with another tilt alpha/2 angles of vertical shaft ［ 9 ］ end.
A key problem in technology is arranged here is ［ 6 ］ with after ［ 9 ］ two inclined planes can rotate relatively, uses bolting again.The gradient on two inclined-planes can addition, also can cancel out each other, thereby it is adjustable that whole swaging is become the angle of vertical rotation, and amplitude is 0～α.Figure 1 shows that a kind of duty of peak angle.This angle should not be too big, general optional 0～3 °.
The moulded head of spreading head can unclamp flange ［ 2 ］ and be changed, and its working curve can newly design according to the shape of workpiece, and its material also can freely be selected, steel such as general available GCr15.
(2) rotating mechanism ［ 9 ］, ［ 10 ］, ［ 13 ］, ［ 14 ］.It has a main shaft ［ 9 ］, bears pressure by bearing ［ 10 ］, is pressed on the flange ［ 11 ］, pressure is relayed on the seat board ［ 12 ］ again, and rotation bearing ［ 13 ］ does not bear the immense pressure of pressing, and has locking effect by locknut ［ 10 ］.
The end of main shaft ［ 9 ］ is connected with rectangular spline with hydraulic motor ［ 17 ］.Therefore when hydraulic motor rotated, main shaft is promptly vertical thereupon vertically to be rotated.
(3) hydraulic unit driver ［ 15 ］, ［ 17 ］.A hydraulic motor fixed disk ［ 15 ］ is arranged, in the middle of hydraulic motor ［ 17 ］ can being fixed on.The pressure oil circuit can directly be introduced wherein.The pressure oil oil circuit here is what to separate with the oil circuit of hydraulic press.
(4) pedestal ［ 11 ］, ［ 12 ］, ［ 16 ］, ［ 18 ］.Three fixing non-rotary steel parts ［ 12 ］, ［ 16 ］, ［ 18 ］ welding processing are integral, and ［ 11 ］ are fixed in the hole of ［ 12 ］, form the pedestal that above-mentioned each parts are installed like this.Hole by on the base plate ［ 18 ］ is fixed by bolts on the hydraulic press, and this has just constituted the integral body of optional feature rotation swaging.
Four parts are joined together by main shaft and four pairs of bearings, and pressure oil can pass through hydraulic drive, make the rotation of spreading head.The work feed of hydraulic press self is pressed on the workpiece moulded head, finishes the pressure processing to workpiece in screwfeed.
The rotating speed of fluid-power motor can be according to the cold and hot state of workpiece and the difference of material, and is stepless adjustable in 1～300 rev/min of scope.
As can be seen from the above description: because this creativity and innovation is with the exert pressure form of hydraulic press to workpiece, become small size (spreading) by large tracts of land (vertical compression),, that is to say so can make pressure usefulness increase 10～15 times, under certain condition, can be with little tonnage hydraulic press when the use of large-tonnage hydraulic press.Simultaneously, completed state also can be done some flexible variation.This processing mode has better effect to plate-like workpiece.This device can be used for transforming original hydraulic press, also can be used on the hydraulic press of new design and manufacturing.Promptly can be used for the press-down type hydraulic press, also can be used for act formula hydraulic press.Preliminary definite: 45 tons to 500 tons of the hydraulic press tonnages that is suitable for.
Again accompanying drawing is indicated below:
Fig. 1: general assembly drawing
Fig. 2: axis of rotation end vertical view
Fig. 3: moulded head vertical view
The major parameter that embodiment adopts:
Hydraulic press tonnage: 45 tons～500 tons
Hydraulic press form: press-down type, last act formula
The speed of mainshaft: 1～300 rev/min, stepless adjustable
Spreading drift angle: α=0～3
Function multiple (pressure): 10～15
