Abstract
The utility model relates to hydraulic drawbench equipment in the mechanical field, in particular to a core bar lifting-supporting device of a hydraulic drawbench, which is composed of an elevating base and a V-shaped groove pulley used for lifting and supporting the core bar of the hydraulic drawbench. The V-shaped groove pulley is arranged on an elevating rod of the elevating base; the number of the V-shaped groove pulley can be one or more, and the V-shaped groove pulley is arranged side by side. The core bar lifting-supporting device takes charge of lifting and supporting the core bar when the drawing of a workpiece is finished, so as to avoid the condition that the core bar is bent and deformed to be damaged due to the lining force of an internal mold at the head of the core bar, so the core bar successfully unloads the internal mold to retract and return to the original position.
Description
Technical field
The utility model relates to the hydraulic pressure cold drawing machine equipment of mechanical field, and the core bar that especially relates to a kind of hydraulic pressure cold drawing machine is lifted rest device.
Background technology
Present drawbench finishes in the workpiece drawing, and workpiece produces the gap between the inside and outside mould after breaking away from internal mold, internal mold since himself gravity effect with sagging.Because it is bigger that internal mold is installed in the head end and the internal mold weight of drawbench core bar, and the connection of the other end of core bar pushes away beam, and mid portion is unsettled, so core bar will be subjected to very big stress effect, not only cause internal mold unloading difficulty, and be easy to make that core bar flexural deformation causes damaging.Present drawbench does not mostly have core bar and lifts rest device, will lean on workman's manual operations when core bar unloading internal mold, lifts core bar by some instruments, not only bothers but also dangerous.
Summary of the invention
The technical problems to be solved in the utility model is: for shortcoming and the deficiency that overcomes prior art, the utility model provides a kind of core bar of drawbench to lift rest device, this device is responsible for lifting the stooling bar after the workpiece drawing finishes, make core bar can unload core insert smoothly and bounce back and reset.
The technical solution adopted in the utility model is: a kind of core bar of drawbench is lifted rest device, forms by lifting pedestal with in order to the V-shaped groove pulley of lifting holder drawbench core bar, and the V-shaped groove pulley is arranged on the elevating lever of lifting pedestal.
Say that further described V-shaped groove pulley is provided with 1, perhaps is arranged side by side several.
The beneficial effects of the utility model are: this device is responsible for lifting the stooling bar after the workpiece drawing finishes, and flexural deformation causes damaging in order to avoid make core bar be subjected to the lining power of head end internal mold, and makes core bar can unload core insert smoothly and retraction resets.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. lifting pedestal 2.V shape groove pulleys among the figure
The specific embodiment
The core bar of a kind of drawbench is as shown in Figure 1 lifted rest device, forms by lifting pedestal 1 with in order to the V-shaped groove pulley 2 of lifting holder drawbench core bar, and V-shaped groove pulley 2 is arranged on the elevating lever of lifting pedestal 1, and V-shaped groove pulley 2 is provided with 1, perhaps is arranged side by side several.
This core bar is lifted rest device and at drawbench the workpiece drawing is finished, and when workpiece broke away from internal mold, it fell base 1 core bar is held in 2 liftings of V-shaped groove pulley, keeps its straightened condition, and core bar unloads core insert and bounces back and resets afterwards, and V-shaped groove pulley 2 rotates thereupon.
The utility model both had protective effect to the drawbench core bar, guaranteed that simultaneously core bar can unload core insert smoothly and retraction resets.
