Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
The structure of the removable frame-type ingot casting of the present invention extrusion device, as shown in Figure 1.Comprise crucible holder 9, crucible holder 9 inboards are provided with crucible support ring 5, are placed with crucible 4 above the crucible support ring 5, and crucible holder 9 is provided with two tracks, and two tracks are provided with travelling car; Travelling car is made up of with top board 8 crossbeam 7, column 2, wheel 3, arm-tie 6; Wherein, be provided with column 2 around the crossbeam 7, column 2 is provided with 4 altogether; Column 2 is provided with wheel 3, and wheel 3 is provided with in orbit, and arm-tie 6 leans on bolt to connect and is fastened on column 2 lower surfaces; Arm-tie 6 is " U " shape, and the arch section of arm-tie 6 is identical with crucible support ring 5 arc radius; Crossbeam 7 is provided with top board 8; Top board 8 is provided with hydro-cylinder 1, and hydro-cylinder 1 is positioned at the top of crucible 4, and the hydraulicefficiency system that hydro-cylinder 1 connects is the adjustable hydraulicefficiency system of top pressure.The turnover oil pipe of hydro-cylinder 1 links to each other with Hydraulic Station through flexible pipe.Wherein, arm-tie 6 upper surfaces are lower than the flange lower surface 2mm ~ 3mm of crucible 4.
Removable frame-type ingot casting extrusion device of the present invention, the hydro-cylinder of installing on the top board 81 is used for ingot casting is extruded, and travelling car integral body can move freely along track.The turnover oil pipe of the hydro-cylinder 1 at top links to each other with Hydraulic Station through flexible pipe.Arm-tie 6 upper surfaces are lower than crucible 4 flange lower surface 2mm ~ 3mm, and travelling car still can free in and out after assurance crucible 4 was placed on the crucible support ring 5.Arm-tie 6 is identical with the arc radius at crucible support ring 5 places, has guaranteed the good fix at removable frame-type ingot casting extrusion device and crucible 4 centers.
When the needs briquetting, the piston rod of hydro-cylinder 1 descends, and after pushing up ingot casting, if the frictional force of ingot casting outside surface and crucible 4 inwalls is during less than travelling car weight, ingot casting will directly be forced out.When frictional force during greater than travelling car weight, travelling car will be by reactive force jack-up, and arm-tie 6 holds on to crucible 4 flange lower surfaces, when the reactive force of hydro-cylinder 1 during greater than the frictional force of ingot casting and crucible 4 ingot casting will be extruded.In the process of whole briquetting; Travelling car stressed acts in the flange and column 2 formed frameworks of arm-tie 6, top board 8, crucible 4; The deadweight that whole crucible support ring 5 and track only bear removable frame-type ingot casting extrusion device, promptly all briquetting strength are system's internal force.
