The specific embodiment
For understanding the present invention better, below in conjunction with the drawings and specific embodiments technical scheme of the present invention is described further, referring to Fig. 1 to Figure 13:
By a kind of clipping base machine that turns over of withholding of the invention process, it includes frame, frame is arranged near between the two workshop roller-ways 7 of milling train hole site, frame is provided with the trolley track 5 with workshop roller-way 7 axially parallels, be connected with cross cylinder 4 on the frame, cross cylinder 4 is connected with travelling car 3, drives travelling car 3 and moves on the trolley track 5 of frame.Travelling car 3 is made up of vehicle frame 301 and wheel, for reaching, the frictional force that reduces to move moves steadily, and the upper wheel 302 that vehicle frame 301 upper and lowers are provided with respectively, lower wheel 303, sidewall then is provided with side guide wheel 304.Switching mechanism 1 is housed on the travelling car 3 and withholds mechanism 2, switching mechanism 1, withhold mechanism 2 respectively by overturning oil cylinder 101 with withhold oil cylinder 201 and drive, the turning wheel of withholding wheel 213 and switching mechanism 1 105 of withholding mechanism 2 cooperates steel billet upset and clamping.Cross cylinder 4 is covered with cross cylinder protective cover 6, and cross cylinder 4 drives travelling cars 3 has two along workshop roller-way 7 axially movable purposes: can make switching mechanism 1, withhold mechanism's 2 initial positions accurately in place be turning wheel 105 be in hot steel billet to be flipped under; Can vertically send into the milling train hole after turning wheel 105 and the steel billet clamping of withholding after wheel 213 will overturn and carry out steel rolling.
Switching mechanism 1 is for being connected the quadric chain on the travelling car 3, it includes overturning oil cylinder 101, upset crank 102, trip shaft 103, upset wheel shaft 104, turning wheel 105, in the hinged car frame 301 of overturning oil cylinder 101 head ends, terminal hinged with upset crank 102 inputs, upset crank 102 outputs are fixedlyed connected with trip shaft 103 head ends, trip shaft 103 is assemblied on the vehicle frame 301 by 2# self lubrication bearing 107, can rotate freely around self axis, trip shaft 103 ends are fixedlyed connected with upset wheel shaft 104, on the upset wheel shaft 104 turning wheel 105 are housed.Turning wheel 105 is lower than 7 absolute altitudes of workshop roller-way when minimum limit position, so that hot steel billet is horizontal not interrupted when mobile under the machine for moving steel effect.
Overturning oil cylinder 101 and withhold electromagnetic proportional valve and the flow valve that oil cylinder 201 all is equipped with the control oil cylinder stroke, in order to guarantee that the angle of revolution speed omega 1 of withholding the angle of revolution speed omega 3 of wheel shaft 212 and the wheel shaft 104 that overturns reaches synchronously (promptly satisfying ω 3 ≈ ω 1) substantially, control with electromagnetic proportional valve and flow valve and to withhold oil cylinder 201 stroke S2 and overturning oil cylinder 101 stroke S1, the proportionate relationship of these two oil cylinder strokes is S2: S1=1: (R
1/ R
2I), (R
1Be the radius of gyration of overturning oil cylinder 101 cranks, R
2For withholding the radius of gyration of oil cylinder 201 cranks, amplify speed-up ratio i=Z
1/ Z
2, Z
1Be gear wheel 208 numbers of teeth, Z
2Be pinion 211 numbers of teeth); When ω 3 and ω 1 have error, withhold four groups of dish spring 205 redeemings that oil cylinder 201 gudgeon places are provided with; Anti-error here causes withholds mechanism 2 and switching mechanism 1 " strength of spraining " and causes mechanism collapse.
Turning wheel 105 and withhold the hot steel billet that wheel 213 needs contact surface high temperature, so both all adopt heat resisting steel, and two-wheeled consumption all easy to wear, so in order in time to be convenient for changing, turning wheel 105 and withhold wheel 213 and adopt and removably connect.Upset wheel shaft 104 end faces are connected with 1# baffle plate 108 by 1# bolt 109, withhold wheel shaft 212 end faces and also be connected with 2# baffle plate 215 by 2# bolt 216, between turning wheel 105 and the upset wheel shaft 104, withhold wheel shaft 212 and be respectively equipped with 1# self lubrication bearing 106 and 3# self lubrication bearing 214 between taking turns 213 with withholding.For the ease of the clamping steel billet, turning wheel 105 and withhold wheel 213 surfaces and all be arranged to concave curved surface.
The invention process process is: after hot steel billet is in place, cross cylinder 4 drives travelling car 3 is under the hot steel billet turning wheel 105, overturning oil cylinder 101 drives upset wheel shaft 104 by 102 swings of driving upset crank and rotates counterclockwise, and turning wheel 105 upper surfaces contact and hold up steel billet with the steel billet lower surface.Simultaneously, withhold oil cylinder 201 drivings and withhold crank 207 swings, by withholding wheel 213 revolution certain angle clockwise after gear wheel 208, pinion 211 transmissions, make and withhold wheel 213 surfaces and contact with the steel billet upper surface and to withhold, withholding wheel 213 clamps steel billet with turning wheel 105, hydraulic system pressure will raise after contact puts in place, and pressure switch signals, and withhold oil cylinder 201 and stop to drive.With the steel billet turning anticlockwise that clamps, make steel billet realize 90 ° of upsets; Cross cylinder 4 drives travelling cars 3 then, withholds wheel 213 and turning wheel 105 and cooperates with workshop roller-way 7 and steel billet is vertically moved and send into the milling train hole carry out steel rolling.
Before next hot steel billet arrives, overturning oil cylinder 101 drives turning wheel 105 and turns round clockwise, it is got back to below the workshop roller-way 7 surperficial absolute altitudes, meanwhile withhold oil cylinder 201 also drive withhold the wheel 213 turning anticlockwises, make and withhold wheel and 213 get back to below the workshop roller-way 7 surperficial absolute altitudes, so that hot steel billet laterally moves under the machine for moving steel effect; Be that turning wheel 105 is got back to the lowest limit position separately with withholding wheel 213, be in holding state, finish a working cycles.
Above disclosed only is preferred embodiment of the present invention, can not limit the present invention's interest field certainly with this, and therefore the equivalence of being done according to the present patent application claim changes, and still belongs to protection scope of the present invention.
