The Lifting Device of the embodiment of the present invention, for the mould 15 of single mode porous form, for ensureing multiple thimbles 26 and mould
Have being accurately positioned of 15 nibs, prevent connecting plate 25 own rotation in motor process, outside connecting plate 25 with guide rod 24
It is provided with between end for preventing between connecting plate 25 and described outer end anti-rotation device in relative rotation, leads including being arranged at
The screw hole of bar 24 outer end, it is arranged at the through hole of connecting plate 25 and through through hole, the screw 27 of screw hole, such as Fig. 2-Fig. 4 institute
Showing, here, the quantity of screw hole matches with the quantity of through hole, and screw role is equivalent to alignment pin, therefore anti-rotation dress
Put and be not limited to use screw.The setting of above-mentioned anti-rotation device, for connecting plate 25 and install being accurately positioned of thimble 26,
Due to the own rotation of guide rod 24 during avoiding using, the thimble 26 caused and the deviations of die hole, make the present invention real
The Lifting Device 2 executing example cannot work.
As shown in Figure 5 and Figure 6, thimble 26 can include threaded portion 263, pars intermedia 262 and leading section 261, wherein, threaded portion
263 and leading section 261 arrange in the both sides of pars intermedia 262 respectively, threaded portion 263 and leading section 261 can be all cylindrical, centre
Portion 262 substantially cylindrical, but also can have stage portion 260 on pars intermedia 262, the cross section of stage portion 260 is rectangle and just
Square, in order to thimble 26 is installed on connecting plate 25 by use instrument.The invention is not limited in that head is circular thimble shape
Formula, can design the thimble form of multi-form according to different Bar Wire Product profiles (namely profile of mould endoporus), with company
Fishplate bar 25 supports the use, the thimble form of the different head shape of the most all this Lifting Device of use, is this patent protection
Scope.
As in figure 2 it is shown, one end that dowel steel 23 is connected with guide rod 24 has T-shaped end 231, guide rod 24 has internal face with outer
Wall, described internal face offers the groove for housing T-shaped end 231, described internal face is provided with for fixing T-shaped end
The fixed plate 241 of 231, fixed plate 241 is fixed on described internal face by bolt 242, it is preferred that fixed plate 241 includes two
Semi-circular shape plate.
As shown in Figure 3 and Figure 4, the through hole on connecting plate 25 includes the first through hole 251 and the second through hole 253, the first through hole
Being arranged above in the center of circle of connecting plate 25, the second through hole 253 is arranged immediately below the described center of circle.And the number of thimble 26 is such as
It is two, can be used for single mode double hole mould or single mode porous mold, then for connecting the screwed hole bag of thimble 26 on connecting plate 25
Including the first screwed hole 252 and the second screwed hole 254, the first screwed hole 252 is arranged on the left of the center of circle of connecting plate 25, the second screw thread
Hole 254 is arranged on the right side of the center of circle of connecting plate 25.
As shown in Figure 7 and Figure 8, the Lifting Device 2 of the embodiment of the present invention, it is installed on the horizontal extruder of the embodiment of the present invention
Master cut 12 side-lower, main cut 12 and be then installed on recipient 16；The side of recipient 16 is vertically above to be provided with and main cuts driving
Oil cylinder 120, master cuts 12 free ends being connected to the main piston rod cut and drive oil cylinder 120.Therefore, main cut driving oil cylinder 120 can
Drive master to cut 12 to move, it is also possible to drive the Lifting Device 2 of the embodiment of the present invention to move simultaneously.
The horizontal extruder of the embodiment of the present invention, may also include control device, controls device and is used for controlling whole horizontal squeeze
The work process of press.After control device detects the extrusion position that extruding billet 4 arrives extruder center 10, show have
Standby extruding condition, then control the driving means of recipient 13, drives recipient 13 to drive the master being installed on it to cut 12 and the present invention
Example material-pulling device 2, to extrusion die lateral movement, controls device and controls to start to extrude action, make billet 4 under extruding force effect
Extruding becomes the setting line of shape, bar, and now billet 4 can be described as extruding billet.
After described control device detects that the extrusion process of billet 4 is terminated by recipient 16, control master and cut driving oil cylinder
120 drive master to cut 12 declines, and the Lifting Device 2 of the embodiment of the present invention cuts 12 declines with main simultaneously, controls device and liftout detected
Device 2 with main cut 12 drop to position, extruder center 10 after, control the main shear blade of 12 cut to more than described extruding billet afterbody
Material is sheared, and extrudes billet and can be referred to as extruded product 3 after shearing, and it is right that control device detects that the main shear blade cutting 12 completes
After the shearing of described extruding billet afterbody clout, the hydraulic cylinder 21 controlled in Lifting Device 2 moves, and promotes thimble 26 to stretch into mould
In 15, release extruded extruded product 3, such as wire rod or bar, and then by traction machine 13 in the effect of less pull strength
Under, it is possible to traction extruded product 3 enters equipment for after-treatment, carries out cooling down, aligns, the postprocessing working procedures such as crop, back-end crop.
Should be understood that multiple example described above can along multiple directions (as tilted, reverse, level, vertical, etc.) and
It is utilized with multiple structures, without departing from the principle of the present invention.Embodiment shown in accompanying drawing is only used as the principle of the present invention
Effectively the example of application and be shown and described, the present invention is not limited to any concrete details of these embodiments.
