Abstract
The utility model discloses an expanding, fixing and extruding pad for an aluminum section extruder. The expanding, fixing and extruding pad comprises an extruding pad body, wherein one side of the extruding pad body is provided with a top pad; the top pad is embedded into the cavity of the extruding pad body and is provided with a bump which extends into the step hole of the extruding pad body; the bump of the top pad fixes the top pad on the step hole of the extruding pad body through a nut; the cavity of the extruding pad body is in conical surface fit with profile of the top pad; a gap is formed between the end face of the top pad close to the extruding pad body and the end face of the extruding pad body; the top pad and the extruding pad body are positioned through positioning pins; and the nut and the end face of the top pad are provided with key grooves, positioned by keys and fixed by screws. The extruding pad is fixed on a thimble of the extruder, so that invalid running time of equipment is shortened and production efficiency is improved; equipment failures caused by personal factors on the extruding pad is avoided; a hollow cavity is formed inside the extruding pad body, so that a top pad cone promotes the expansion of an internal conical surface of the extruding pad body; when the end face of the top pad is fully close to the end face of the extruding pad body, the extruding pad expands to the maximum extent for extruding; and when extrusion is finished, the extruding pad body recovers to the original size, so that wear of a mold barrel and the extruding pad is reduced.
Description
Technical field
The utility model relates to a kind of fixation extrusion pad that is applicable to the non-ferrous metal heat extruder.
Background technology
Present aluminium section bar extruder generally all adopts independent solid dummy block, in use every extruding once must be by manually taking out in the connection pad bucket of special use, put into the back of material supporting rack aluminium bar then, again by thimble together with bar together the propulsion module tube push, operate loaded down with trivial detailsly like this, prolong ineffective time, reduce production efficiency, and may be because personnel's carelessness forgets that the situation of putting dummy block happens occasionally, and causes the aluminium bar locking phenomenon.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can be fixed on the fixation extrusion pad that need not dismantle again on the thimble of extruder.
The technical solution of the utility model is:
A kind of aluminium section bar extruder expansion fixation extrusion pad comprises the dummy block body, and a side of dummy block body is provided with the top pad, and the top pad embeds the dummy block chamber body.
Top pad is provided with in the stepped hole that projection stretches into the dummy block body, and the projection of top pad is fixed on the stepped hole of dummy block body the top pad by nut;
The inner chamber of dummy block body is a cone match with the profile of top pad;
Gapped between the end face of the close dummy block body of top pad and the end face of dummy block body;
Locate by alignment pin between top pad and the dummy block body;
Nut has keyway with top pad end face, and by being located by key, screw is fixed.
Beneficial effect: dummy block of the present utility model is fixed on the thimble of extruder, minimizing equipment invalid running time, has improved production efficiency; Dummy block is fixed on the thimble of extruder, the equipment fault of avoiding old-fashioned dummy block human factor to cause, make top pad cone promote dummy block body inner conical surface to expand owing to offer the casement chamber in the dummy block body, when the end face of top pad and extrusion body end face are pressed close to fully, make dummy block be expanded to dimension limit and push, extruding finishes back dummy block body and returns to life size, reduce the wearing and tearing of mould tube and extruding, save cost, enhance productivity, energy savings and raw material reduce cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that enlarged drawing is looked on the right side of top pad 2, nut 3, key 4 and screw 5 among Fig. 1.Among the figure, the end face of 1-dummy block body, 2-top pad, 3-nut, 4-key, 5-screw, 6-alignment pin, 7-dummy block body 1, end face, the internal thread of 9-dummy block body 1, the 10-casement chamber of 8-top pad 2.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of aluminium section bar extruder expansion fixation extrusion pad comprises dummy block body 1, and a side of dummy block body 1 is provided with top pad 2, and top pad 2 embeds dummy block body 1 inner chamber.
The projection that is provided with top pad 2 stretches in the stepped hole on the dummy block body 1, and the projection of top pad 2 makes on pad 2 stepped holes that are fixed on the dummy block body 1 of top by nut 3.
The inner chamber of dummy block body 1 is a cone match with the profile of top pad 2.
Gapped between the end face 8 of top pad 2 close dummy block bodies 1 and the end face 7 of dummy block body 1.
Locate by alignment pin 6 between top pad 2 and the dummy block body 1.
