Abstract
The invention discloses a device for detaching a liner of an extruder. The device comprises a frame; the top of the frame is provided with a hydraulic jack; the hydraulic jack is externally connected with a hydraulic system; the bottom of the hydraulic jack is provided with a piston rod; the diameter of the piston rod is greater than the diameter of an inner hole of the liner and is smaller than the outer diameter of the liner; a workbench is arranged at the bottom of the frame and is provided with a blanking hole opposite to the piston rod; the diameter of the blanking hole is greater than the outer diameter of the liner and is smaller than the diameter of a liner jacket. The device is easy to operate, safe to use and high in liner detaching speed, can avoid a condition that the liner jacket is scrapped, and is mainly used for detaching the liner of the extruder from the liner jacket.
Description
Technical field
The present invention relates to the equipment technical field of changing for extruder material courage, the provision for disengagement of especially a kind of extruder material courage.
Background technology
In the extruding workshop of aluminium section bar processing factory, often run into dismounting and the installation of material courage and material courage overcoat.At present, the dismounting of material courage often adopts manually and completes, and workman adopts sledgehammer that material courage is pounded out in courage overcoat by expecting, so that the material courage more renewing.Because temperature after material courage and the use of material courage overcoat is high especially, interference fit is very tight, is not only difficult to dismounting, operational hazards, but also easily cause scrapping of material courage overcoat.Therefore, designing a kind of extruder material courage provision for disengagement that can address the above problem well is extremely necessary.
Summary of the invention
Object of the present invention will solve exactly tradition and adopt artificial unloading to expect that courage easily causes that workman is injured, dismounting is more difficult and material courage overcoat such as scraps at the problem, and a kind of extruder material courage provision for disengagement that can overcome preferably above-mentioned defect is provided.
Concrete scheme of the present invention is: the provision for disengagement of a kind of extruder material courage, it is characterized in that: there is frame, frame top is equipped with hydraulic jack, the external hydraulic system of hydraulic jack, hydraulic jack top/bottom part is provided with piston rod, and the diameter of piston rod is greater than expects the diameter of bore of courage but is less than the external diameter of expecting courage; Frame bottom is furnished with workbench, has the just material-dropping hole to piston rod on workbench, and the diameter of material-dropping hole is greater than the diameter of expecting the external diameter of courage but be less than material courage overcoat.
For convenient lifting material courage assembly, and by material courage assembly be placed on hydraulic jack under, the present invention is provided with two horizontally disposed guide rails between workbench and frame bottom, two guide rails layouts that all extend outwardly, and workbench is connected with two guide rails rollings by the wheel that is arranged on bottom.
For convenient cooling to expecting that courage carries out, make to expect that courage more easily splits out from material courage overcoat, the present invention is provided with the sparge pipe that points to material-dropping hole at frame top.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: 1-guide rail, 2-wheel, 3-workbench, 4-material-dropping hole, 5-material courage overcoat, 6-expects courage, 7-endoporus, 8-frame, 9-sparge pipe, 10-piston rod, 11-hydraulic jack, 12-hydraulic system.
Detailed description of the invention
Referring to Fig. 1, the present invention has frame 8, and hydraulic jack 11 is equipped with at frame 8 tops, the external hydraulic system 12 of hydraulic jack 11, hydraulic jack 11 bottoms are provided with piston rod 10, and the diameter of piston rod 10 is greater than the diameter of the endoporus 7 of expecting courage 6 but is less than the external diameter of expecting courage 6.Frame 8 bottoms are furnished with workbench 3, have the just material-dropping hole 4 to piston rod 10 on workbench 3, and the diameter of material-dropping hole 4 is greater than the diameter of expecting the external diameter of courage 6 but be less than material courage overcoat 5.
Between workbench 3 described in the present embodiment and frame 8 bottoms, be provided with two horizontally disposed guide rail 1, two guide rails 1 layout that all extends outwardly, workbench 3 is connected with two guide rails 1 rollings by the wheel 2 that is arranged on bottom.
The top of frame 8 described in the present embodiment is provided with the sparge pipe 9 that points to material-dropping hole 4.
When specific works, material courage 6 and material courage overcoat 5 are lifted on workbench 3, allow material courage 6 just material-dropping hole 4 be placed, workbench 3 is pushed under liquid presses piston pole 10, open sparge pipe 9 material courage 6 is sprayed water cooling, primer fluid pressing system 12, the downward operation of piston rod 10 of hydraulic jack 11 will expect that courage 6 is by expecting extrusion in courage overcoat 5, material courage 6 is dropped into the bottom of frame 8 by the material-dropping hole 4 on workbench 3, completed the dismounting of material courage 6.
By reference to the accompanying drawings embodiments of the invention are described above, but the present invention is not limited to above-mentioned detailed description of the invention, above-mentioned detailed description of the invention is preferred forms of the present invention, is only schematically, instead of restrictive.Those of ordinary skill in the art is under enlightenment of the present invention; do not departing from the scope situation that aim of the present invention and claim protect; the selection of size, specification and the material of guide rail 1, wheel 2, workbench 3, material-dropping hole 4, material courage overcoat 5, material courage 6, endoporus 7, frame 8, sparge pipe 9, piston rod 10 and hydraulic jack 11 in the present invention; can adjust according to actual needs; as long as the change that these are adjusted without substantive principle, all belongs to protection scope of the present invention.
