Abstract
The utility model relates to an extruder, composed of an oil cylinder 1, a piston 2, a stress rack 9, a combined mold 10, a bottom plate 11 and a pushing mechanism. The oil cylinder 1, the stress rack 9 and the bottom plate 11 successively form screw connection; the pushing mechanism is composed of an end cover 3, a shim plate 5, a pushing and pressing head 7, a stopper 8 and an ejector rod 6 arranged between the end cover 3 and the stopper 8; the end cover 3, the shim plate 5, the pushing and pressing head 7, the stopper 8 and the ejector rod 6 successively form the screw connection; the ejector rod 6 and the stopper 8 form the screw connection; a spring 4 is arranged between the end cover 3 and the ejector rod 6; the pushing mechanism is fixedly connected with the piston 2 in the mode of screw connection through the shim plate 5. The extruder has the nominal advantages of great extruding force, favorable extruding effect, simple operation and convenience.
Description
The utility model relates to a kind of large-size extruder for preparing the squash type ground tackle of prestressing force external tendon.
Existing squeezer mainly is made up of oil cylinder, piston, roof pressure head, combination die etc., and this kind squeezer volume is little, is only applicable to single steel hinge line.
The purpose of this utility model is to provide a kind of nominal extruding force big, is applicable to many steel hinge lines, is specially adapted to push the squash type prestressed anchor of prestressing force external tendon, extruder simple to operation.
For reaching above-mentioned purpose, the extruder of the utility model improves on existing squeezer basis, oil cylinder volume and piston thrust have been increased, particularly on former roof pressure head basis, increased a top-pushing mechanism, this top-pushing mechanism by the end cap that is threaded in turn, backing plate, roof pressure head and stopper and be positioned at end cap and stopper between push rod constitute, push rod is threaded with stopper; Between end cap and push rod spring is arranged, top-pushing mechanism is fixedly linked with thread connecting mode and piston by backing plate.
Because adopt said mechanism, the extruder of the utility model has following advantage:
1, the nominal extruding force is big, and squeezing effect is good.Because top-pushing mechanism is arranged, can guarantee that plug passes through assembling die synchronously with pressing body in extrusion process.Be specially adapted to many steel hinge lines is the squeeze job of squash type prestressed anchor of the prestressing force external tendon of reinforcing bar.
2, simple, convenient.
Below, the architectural feature to the extruder of the utility model is further described in conjunction with the accompanying drawings and embodiments:
Accompanying drawing: the structural representation of the extruder of the utility model
As shown in the figure, the extruder of the utility model is made of oil cylinder 1, piston 2, stressed 9, combination die 10, base plate 11, top-pushing mechanism, oil cylinder 1 is threaded successively with stressed 9, base plate 11, this top-pushing mechanism is made of the end cap 3 that is threaded in turn, backing plate 5, roof pressure head 7 and stopper 8 and the push rod 6 between end cap 3 and stopper 8, and push rod 6 is threaded with stopper 8; Between end cap 3 and push rod 6 spring 4 is arranged, top-pushing mechanism is fixedly linked with thread connecting mode and piston 2 by backing plate 5.
