Description
Technical field the utility model relates to a kind of frequency conversion type friction press, can be widely used in the forging industry.
The existing friction press of background technology does not all adopt the VFC mode, and often the equipment running process power consumption is big, and cost is high, has increased many costs to equipment user.
The purpose of summary of the invention the utility model is to provide a kind of simple in structure, safe and reliable, processing ease, easy to maintenance, VFC, energy-saving and cost-reducing, cost is low, the forging scope of application is big, mould is easy to adjust, hitting power is big, forging precision is high, forming accuracy is high frequency conversion type friction press.
In order to achieve the above object, the utility model frequency conversion type friction press comprises frame; Rack-mounted VFC motor is connected and has the frequency-converting control device of frequency converter, rack-mounted horizontal drive shaft with the VFC motor; The left frictional disk that is installed on the horizontal drive shaft and drives by the belt drive of VFC motor; Be installed on the horizontal drive shaft and with horizontal drive shaft rotate right frictional disk, alternately press the flywheel of friction-driven by left and right two frictional disks, be installed in the copper nut in the housiung separator hole; Be installed in the screw rod on the flywheel, by the slide block of screw rod through the screw pair driving.
The utility model frequency conversion type friction press, its operation principle is: screw rod upper end and flywheel rigid attachment, the lower end links to each other with slide block; Change rotatablely moving of flywheel and screw rod the upper and lower rectilinear motion of slide block into by copper nut, motor drives frictional disk through belt pulley and rotates, when when down stroke begins; Promote a frictional disk and compress flywheel, the rotation of rubbing flywheel, slide block down; Flywheel quickened and obtained kinetic energy this moment, and the moment before hitting workpiece, frictional disk and flywheel disengage; Slide block releases energy until stopping with speed that had this moment forging and pressing workpiece; After forging and pressing were accomplished, the beginning backhaul at this moment, promoted another frictional disk and compresses flywheel; The reverse rotation of rubbing flywheel, slide block promotes rapidly, and to a certain position, frictional disk and flywheel disengage; Slide block continues freely to make progress slip, and slide block slows down, until stopping; Like this, move up and down once, promptly accomplished an operation cycle.
The utility model frequency conversion type friction press, during slide block movement, the VFC motor is not worked, and not power consumption mainly leans on the axes of inertia to drive, and when slide block was static, the VFC motor quickened to replenish the flying wheel energy.
The utility model frequency conversion type friction press, simple in structure, safe and reliable; Processing ease; Easy to maintenance, its equipment investment, die cost and forging cost are all cheap half the many than die hammer and hot forging crank press, compare with imported product; The performance basically identical, but price is merely 1/4 of imported product.
The utility model frequency conversion type friction press, VFC motor are when rotating speed reduces, and energy consumption reaches purpose of energy saving also along with reduction.During starting, current of electric steadily increases, and does not impact, and makes the electrical equipment of electrical network and equipment can both receive protection.
The utility model frequency conversion type friction press, owing to adopt the operation of Frequency Converter Control motor, motor outage during slide block down, descending strike rotating speed reduces, energising when slide block is up, the backhaul makeup energy is quickened.Like this, suitably reduce the running speed of motor, guaranteed the ordinary production of forcing press, practiced thrift electric energy again effectively.Economize on electricity 30%～50% reduces cost, and realizes energy saving purposes.
The utility model frequency conversion type friction press, the VFC motor can steadily quicken or slow down, and electric current also can smooth change when quickening and slow down, and does not impact, and electrical network and element can both be protected.
The utility model frequency conversion type friction press has the double grading and the advantage of die hammer and hot forging crank press concurrently.At first; It has certain percussion in the course of the work, and ram travel is unfixing, and this is the characteristic of hammer kind equipment; Make it in a type groove, can repeatedly hit distortion, thereby can big deformation energy and certain hammering power be provided for large deformation jumping-up, extrusion process; Simultaneously; It is again to transmit energy through screw pair, and in the moment of metal generation plastic deformation, power suffered between slide block and the workbench is born by pressure machine closed framework; And form seal force system; This point is the characteristic of hot forging crank press, thereby also can be for small deformation pressure-sizing, impression operation provide bigger deformation force and certain deformation ability, so can satisfy the power ability requirement of various main forging and pressing operations.Therefore, the forging scope of application is big.
The utility model frequency conversion type friction press is compared with the hot forging crank press, and device travel is variable, does not have fixing bottom dead centre.Therefore, mould is easy to adjust, is particularly suitable for the production of the frequent small batch forging of die change.And the bottom dead centre of hot forging crank press is fixed; Stroke and pressure can not regulated at will; Suitablely extend, manufacture craft such as edging, the heating quality of blank surface is required also higher, do not allow too much oxide skin; Especially when equipment operation or the mould adjustment is improper and blanking inaccurate or excess load when using, might make slide block vexed car take place and breaks in production near bottom dead centre the time.
The utility model frequency conversion type friction press, general hitting power allows for 1.6 times of nominal pressure, and the hot forging crank press is because of " vexed car " easily, generally hitting power only allows to use 70%～80% of its nominal pressure.Therefore, the forcing press of same specification, the maximum hitting power of double plate friction press is 2 times of hot forging crank press.
The utility model frequency conversion type friction press; Forging precision is high; The dimensional accuracy pattern tool of forging " is beaten and leaned on " and the precision die forging guide pillar leads guarantees, do not receive the influence of equipment self strain, thereby many in recent years factories utilizes all friction press to carry out precision die forging.
The utility model frequency conversion type friction press, the vexed mould time is short, is merely hot forging crank press 1/2, can guarantee that the precision of each forging is consistent, and forming accuracy is high.And the hot forging crank press is because near slide block movement velocity bottom dead centre is the slowest; Not only workpiece time of staying in mould long, die life is short, and to some mainly by being pressed into the forging of mode packed type groove; Though might produce bigger burr, and still underfill type groove depth place.
The utility model frequency conversion type friction press is applicable to the compression moulding work of die forging, extruding, side cut, bending, correction and the fire resistive material product of coloured and ferrous metal.
In sum, the utility model frequency conversion type friction press, simple in structure, safe and reliable, processing ease, easy to maintenance, VFC, energy-saving and cost-reducing, cost is low, and the forging scope of application is big, and mould is easy to adjust, and hitting power is big, and forging precision is high, and forming accuracy is high.
