Abstract
A drawing device of a long silver-base alloy bar relates to the improvement of the metal bar drawing device, which is characterized in that the structure of a chain-type drawbench comprises drawbenche stand box bodies on the two ends, two guide rails arranged between and upon the drawbenche stand box bodies, and a bar-drawn support device with a bottom fixed on the base. Through the support to the bar by an aeroelastic underroller during the drawing process, the bar can be prevented from drooping caused by dead weight, and the uniformity and consistency of the sizes of the bars are ensured during the drawing process. A drawing cart triggers the switch contact of the aeroelastic underroller during the drawing process, so the aeroelastic underroller rises, and the operation is convenient.

Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, and a kind of draw-off gear that the long bar of silver-base alloy that solves the bar stretched dimension problem of non-uniform of removing bar self gravitation influence generation can be arranged is provided.
The purpose of this utility model solves by the following technical programs.
The draw-off gear of the long bar of a kind of silver-base alloy, it is characterized in that comprising the middle position of two guide rails that between two ends broaching machine support casing and two ends broaching machine support casing, are provided with, be fixed on the bar bracing or strutting arrangement that is stretched on the basis bottom being provided with top in the structure of chain type broaching machine.
The draw-off gear of the long bar of a kind of silver-base alloy of the present utility model is characterized in that the described structure that is stretched the bar bracing or strutting arrangement comprises:
Device pedestal-this base is that the bottom is fixed on the basis;
Bracing or strutting arrangement lift cylinder-this lift cylinder bottom is vertical with device pedestal affixed;
Elastic support-this elastic support comprise be fixed on bracing or strutting arrangement lift cylinder valve rod top soleplate, be vertically fixed on spring reference column on the base plate, be sleeved on spring fixed column spring, be fixed on the trunnion axis of spring upper end;
It is to take turns the moving runner that end face has groove that the bar that is stretched supports support roller-this support wheel, and moving runner cooperates connection with the trunnion axis of elastic support.
The draw-off gear of the long bar of a kind of silver-base alloy of the present utility model is characterized in that being provided with the touch controls switch in the vertical bar shaped lateral wall plate inboard that is positioned at the guide rail both sides, establishes the interlock of switch and support arrangement lift cylinder control system.
The draw-off gear of the long bar of a kind of silver-base alloy of the present utility model, comprise between two ends broaching machine support casing and two ends broaching machine support casing and the middle position of two guide rails that top is provided with in the structure of chain type broaching machine, be provided with the bottom and be fixed on the bar bracing or strutting arrangement that is stretched on the basis.By aeroelasticity support roller in the drawing process bar is imposed support, it is sagging to prevent to conduct oneself with dignity, and has guaranteed the uniformity consistency of bar size in the drawing process.The stretching dolly triggers the switch contact of pneumatic support roller in drawing process, the elasticity support roller rises, and is easy to operate.
