Abstract
The utility model relates to a hollow induction extrusion rod, which comprises a hollow extrusion rod, a central rod, a spring and a contactor. The hollow induction extrusion rod is characterized in that 1 the central rod is sleeved inside the hollow extrusion rod, thereby prolonging service life; and 2 the central rod recedes when the central rod bears force, the spring arranged at the rear end of the central rod is contacted with the contactor, and a power supply of an extruder is powered off, thereby avoiding machinery accidents caused by the fact that an extrusion cake is assembled reversely or the extrusion cake is not assembled.
Description
One, technical field: the utility model relates to a kind of pressure ram, is specifically related to the supporting pressure ram of extruder in the aluminium section bar manufacturing enterprise.
Two, background technology: used pressure ram all is solid pressure ram in the existing aluminium section bar manufacturing enterprise, is made of solid pressure ram and thimble two parts.In extrusion process, instead or not go up the phenomenon of pushing cake and continuing to push on the inevitable extruding cake, if do not find in time that pressure ram is subjected to force unbalance can cause the generation of phenomenons such as pressure ram fracture or pressure ram can't separate with the adhesion of high temperature aluminium bar, has a strong impact on normally carrying out of production.
Three, summary of the invention: the purpose of this utility model just provides a kind of preventing will push the pressure ram that causes mechanical accident when instead or not upward the extruding cake pushes on the cake because of mistake in workman's operating process.
The hollow induction pressure ram of the utility model mainly is made of hollow pressure ram, center-pole, spring, contactor four parts, center-pole is enclosed within the hollow pressure ram, master cylinder drives pressure ram and advances, when instead or not going up the extruding cake on the extruding cake, center-pole top in the hollow pressure ram is not enclosed within will be stressed in the groove that pushes cake, and the tail end of stressed rear center bar drives spring and retreats the conflict contactless contactor, the extruder power supply will automatic disconnection, and pressure ram halts.
The utility model compared with prior art has following characteristics: 1. because in the hollow pressure ram, have one to be cylindrical hollow, its internal diameter is slightly larger than the diameter of center-pole, movable center-pole is inserted in the hollow pressure ram, increasing 2. the two ends of center-pole service life exposes beyond the hollow pressure ram, the top of exposing places in the extruding cake groove, and tail end links to each other with contactor, has reduced the frequency of the improper mechanical accident that causes of manual operation.
Four, description of drawings:
Fig. 1 is a structure cutaway view of the present utility model;
Fig. 2 is the utility model extruding cake forward structure schematic diagram;
Fig. 3 is the utility model extruding cake reverse geometry schematic diagram;
Five, the specific embodiment:
Embodiment 1: referring to Fig. 1, Fig. 2, the utility model is made of hollow pressure ram 1, center-pole 2, spring 3, contactor 4 four parts.Center-pole 2 is enclosed within the hollow pressure ram 1, is installed on the butterfly 6 of extruder master cylinder.In the extrusion process, when extruding cake 5 forwards were placed, the top of center-pole 2 was enclosed within the groove of extruding cake 5, and center-pole 2 does not touch object can be not stressed; Referring to Fig. 3, on extruding cake 5 instead or when not going up, the top of center-pole 2 is not enclosed within the groove that pushes cake 5, contacting its end of stressed back will compress spring 3 and retreat with object, after the thimble of spring 3 was run into contactor 4, the extruder power supply will automatic disconnection, and pressure ram halts.
