Description
A kind of awl roller rivet bucker, the utility model belongs to forging press.
Present existing forging press has polytype, and hydraulic press, crank press, fly press all are the static pressure process equipments, big energy-consuming, and technology power is big, volume and from great, cost height; The yaw of rotary forging machine is complicated spheric motion, and the rotation of restriction yaw, between instrument (roll) and the workpiece sliding friction is arranged, and power consumption is big, and main motor current is big.During hot-working, after the spheroid of kinematic pair was met thermal expansion, spherical shell easy and kinematic pair got stuck.The instrument of rotary forging machine and the contact area between workpiece change the position with the swing of yaw, thereby the eccentric cyclically-varying of technology power force action line position, and the machine element stress worsens, and has increased equipment manufacturing cost; Axially in the milling train process, the mould that workpiece is installed ceaselessly moves, and needs mould static during upper and lower workpiece, thereby mould gets and stop continually and starts, promptly influences productivity ratio, big energy-consuming again, and operation is also inconvenient.Axially rolling mill technology power force action line off-centre influences the control of equipment rigidity and machining accuracy.
The purpose of this utility model is a kind of rotation pressure head that has of design, and each kinematic pair is plane motion and pays, the mould transfixion of supporting workpiece, and instrument (cone-shaped roll) rolls at surface of the work and depresses, and is the awl roller rivet bucker of rolling friction between instrument and the workpiece.
Feature of the present utility model is that hydraulic cylinder 1 is fixed on the entablature of lathe bed 2, rotary head pressure 6 is on the moved cross beam 4 of guide rail by the column that bearing is installed in lathe bed 2, motor 3, decelerator 5 are installed on the moved cross beam 4, motor 3 drives by decelerator 5 and rotates pressure head 6 rotations, hydraulic cylinder 1, lathe bed 2, to rotate pressure head 6 coaxial, on the axis bilateral symmetry position of rotating pressure head 6, respectively hand over a bit altogether at the axis that rotates equal-sized cone-shaped roll 7, two awl rollers 7 of installation on the pressure head 6 and the axis of movable pressure head 6 by bearing.
Below in conjunction with accompanying drawing the utility model is specified:
Fig. 1 bores roller calender structure schematic diagram
The contact area of Fig. 2 instrument (cone-shaped roll) and workpiece
Awl roller rivet bucker is made up of Hydraulic Station (not shown), lathe bed 2, rotation pressure head 6 three parts.The structure of lathe bed 2 is that three road crossbeams are arranged on the column, fixing on the entablature and the hydraulic cylinder 1 that rotates pressure head 6 coaxial lines, hydraulic cylinder 1 is connected fixed mould on the sill with Hydraulic Station, mould upper support workpiece 8, upper and lower crossbeam is linked to be rigid unitary through column with lathe bed 2.Middle moved cross beam 4 is a guide rail with the column, piston at hydraulic cylinder 1 pushes away, draws the upper and lower translation of effect lower edge lathe bed 2 axis, be equipped with on the moved cross beam 4 motor 3, decelerator 5, with the rotation pressure head 6 of bed piece 2 coaxial lines, rotating pressure head 6 is installed on the moved cross beam 4 by bearing, rotate pressure head 6 in upper and lower motion, can under the driving of motor 3, be rotated motion with moved cross beam.On the axis bilateral symmetry position of rotating pressure head 6, respectively rotating equal-sized cone-shaped roll 7 of installation on the pressure head 6 by bearing, the axis of two awl rollers 7 is handed over a bit altogether with the axis that rotates pressure head 6, its angle is α, the cone-apex angle of cone-shaped roll 7 is (π-2 α), each awl roller 7 all can be around rotating from axle, awl roller 7 both can be revolved round the sun with rotating pressure head 6, again can be around rotating from axle, like this, when awl roller 7 moves down into after workpiece 8 contact with rotating pressure head 6, can be along with the rotation of rotating pressure head 6 on workpiece 8 around depressing from axle rotation and rolling.
Before the work of awl roller rivet bucker, earlier workpiece 8 is installed in the mould that is fixed on lathe bed 2 sills.Motor 3 drives by decelerator 5 and rotates pressure head 6 around axle rotation certainly.Start the hydraulic cylinder of connecting with Hydraulic Station 1, it is descending that the piston of hydraulic cylinder 1 promotes moved cross beam 4, when cone-shaped roll 7 along with moved cross beam 4, rotate pressure head 6 move down on the surface that is pressed onto workpiece 8 time, cone-shaped roll 7 is touched frictional force drives around an axle reverse rotation certainly, forming cone-shaped roll 7 depresses in workpiece 8 surface rollings, thereby realize that awl roller 7 rolls in the local contact pressurization of workpiece 8 axial ends, makes workpiece 8 continuous modifications.The contact area 9 of awl roller 7 and workpiece 8 as shown in Figure 2.When depression stroke reached requirement, moved cross beam 4 stopped descending, rotated pressure head 6 after 1 week of rotation under the feed-disabling state, and is up with moved cross beam 4 backhauls, unloads workpiece 8, finishes a working cycles.
Compare with static pressure process equipments such as existing hydraulic press, crank press, fly presses, because of instrument is that cone is rolled at surface of the work, reduced compressive load per unit area for rolling friction therebetween, the local contact of the conical surface and area is very little, so process onesize workpiece, the total power of technology power (plastic deformation force) is dwindled greatly, thereby ability/deadweight value enlarges several times.
Compare with existing rotary forging machine, axial milling train: 1. technology power is little, static pressure, and friction, Noiselessness; 2. movement parts is simple Plane Rotation motion, and is simple in structure, operates steadily, suitable Ying Leng, temperature, hot various plastic workings; 3. local contact the between instrument and workpiece, the symmetrical branch of contact-making surface Cloth, technology power force action line is by machine axes, and invariant position, and element of installation does not bear week Phase stress, fatigue life is long; 4. changed the sliding friction between roll and workpiece into rolling friction, Its coefficient of friction is little, and the plastic deformation consumed power only is 55%～63% of rotary forging machine, energy-conservation effect Fruit significantly; 5. counterdie transfixion, upper and lower workpiece is convenient.
