Abstract
The utility model relates to an aluminium material extruder dummy block with an aluminium slot on a taper sleeve, comprising a taper sleeve, a cone pad, a fastener and etc., wherein an annular aluminium slot is arranged on an outer diameter of the taper sleeve. The outer diameter of the taper sleeve at the rear part of the slot body of the aluminium slot is 0.2-0.5 mm greater than that of the front part. The section of the aluminium slot is an arc and also may be a trapezoid or a rectangle. The aluminium material extruder dummy block provided by the utility model can store the metal extruded from a gap between the taper sleeve and an extrusion cylinder in the aluminium slot, reduce or prevent the overflow metal from scoring the extrusion cylinder, prolong the service lives of the extrusion cylinder and the dummy block and improve the production efficiency.
Description
Technical field
The utility model relates to a kind of technological improvement of aluminium section bar extruder dummy block, has the aluminium extruder dummy block that contains the aluminium groove on especially a kind of tapered sleeve.
Background technology
At present, the tapered sleeve and the cone pad of aluminium extruder dummy block are all taked the pre-large post-small conical surface, and the inner surface of tapered sleeve matches with the conical surface of cone pad.When before dummy block contacts with the blank that is extruded, being free state, between cone pad and the recipient inner surface and between cone pad and the securing member certain interval is arranged all.When the extrusion axis promotion dummy block that advances; Dummy block is just with certain pressure extrusion metal blank, under the effect of the reaction force of metal stock, forces the cone pad inwardly to move; Till eliminate in the gap between cone pad and firm; Tapered sleeve outwards expands under the effect of the cone pad conical surface with matching simultaneously, makes tapered sleeve outer surface and the tight applying of recipient inner surface, prevents to be extruded the possibility that metal stock is clamp-oned under the effect of oppositely overflowing.But because the tapered sleeve bulk is wayward, bulk is crossed conference damage recipient inner surface, and the not enough envelope of bulk incessantly is extruded oppositely overflowing of metal.Especially along with the dummy block wearing and tearing; The gap of the outer surface of tapered sleeve and recipient inner surface is strengthened gradually; Metal oppositely overflows the chance increasing during extruding; Clamp-on tapered sleeve outer surface and recipient internal surface gaps chance also along with increase, cause the accident and shorten the dummy block possibility in service life thereby increased.
Summary of the invention
The utility model can not effectively be got rid of the deficiency that is squeezed into its tapered sleeve outer surface and recipient internal surface gaps metal to existing dummy block; Provide and have the aluminium extruder dummy block that contains the aluminium groove on a kind of tapered sleeve; On this tapered sleeve contain the aluminium groove have harvest and store be squeezed in the gap between tapered sleeve and the recipient oppositely overflow metal function; Reduce the recipient damage, prolong the service life of recipient and dummy block.
The utility model solves the technical scheme that its technical problem adopted: have the aluminium extruder dummy block that contains the aluminium groove on the tapered sleeve of being made up of tapered sleeve, cone pad, securing member, its characteristics are on the external diameter of tapered sleeve, to establish an annular and contain the aluminium groove.
In the implementation of the utility model, described being located at contains aluminium groove, the big 0.2～0.5mm of tapered sleeve external diameter that the tapered sleeve external diameter at its cell body rear portion is more anterior than cell body on the tapered sleeve external diameter.
In the implementation of the utility model, the described cross section that contains the aluminium groove is an arc, also can be trapezoidal or rectangle.
The utility model is established an annular and is contained the aluminium groove on the external diameter of tapered sleeve; Be used to store that clamp-on in the gap between tapered sleeve and the recipient oppositely overflows metal; The scuffing that reduces or prevent to overflow the metal pair recipient can prolong service life of recipient and dummy block, enhances productivity.
Description of drawings
Below in conjunction with Figure of description and embodiment the utility model is further specified
Fig. 1 is the main TV structure sketch map of the utility model
Among the figure: 1, securing member; 2, tapered sleeve; 3, contain the aluminium groove; 4, recipient; 5, cone pad.
The specific embodiment
In the drawings: the utility model is to have the aluminium extruder dummy block that contains the aluminium groove on a kind of tapered sleeve; Form by tapered sleeve, cone pad, securing member; Its characteristics are on the external diameter of tapered sleeve (2), to establish an annular and contain aluminium groove (3), and the tapered sleeve external diameter that contains aluminium groove cell body rear portion is than the big 0.2～0.5mm of anterior external diameter.The cross section that contains the aluminium groove is an arc, also can be trapezoidal or rectangle.
This structure is the same with other existing dummy blocks, when before dummy block contacts with the blank that is extruded, being free state, between tapered sleeve (2) outer surface and recipient (4) inner surface and between cone pad (5) and the securing member (1) certain interval is arranged all.When the extrusion axis promotion dummy block that advances; Dummy block is just with certain pressure extrusion metal blank, under the effect of the reaction force of metal stock, forces inwardly motion of cone pad (5); Till eliminate in the gap between cone pad and the securing member (1); Simultaneously tapered sleeve (2) outwards expands under the effect of cone pad with matching (5) conical surface, makes tapered sleeve (2) outer surface and the tight applying of recipient (4) inner surface, and the metal stock that prevents to be extruded is oppositely overflowing the possibility of clamp-oning under acting on.But because the tapered sleeve bulk is wayward, bulk is crossed conference damage recipient inner surface, and the not enough envelope of bulk incessantly is extruded oppositely overflowing of metal.Especially along with the wearing and tearing of dummy block; The gap of the outer surface of tapered sleeve and recipient inner surface is strengthened gradually; Metal oppositely overflows the chance increasing during extruding; The chance of clamp-oning gap between tapered sleeve outer surface and the recipient inner surface is also along with increase, thus increase accident and the shortening dummy block possibility in service life.The utility model is established one and is contained aluminum annular-shaped groove (3) on dummy block tapered sleeve (2); Like this when extruding; The metal entering annular that is oppositely overflowed into by gap between tapered sleeve outer surface and the recipient inner surface contains the storage of aluminium groove; Pad to be extruded returns when arriving free state and removes, and gets into crush stroke next time then.
The utility model through Jilin Mai Dasi Aluminum Co., Ltd on probation, respond well, contact surface does not have and oppositely overflows metal residual between recipient and the dummy block, no extrusion cycle time decreased, 1.2 times of production efficiency raisings, dummy block prolongs 2 times service life.
Claims (3)
1. have the aluminium extruder dummy block that contains the aluminium groove on a tapered sleeve, form, it is characterized in that on the external diameter of tapered sleeve (2), establishing an annular and contain aluminium groove (3) by tapered sleeve, cone pad, securing member.
2. according to having the aluminium extruder dummy block that contains the aluminium groove on the said a kind of tapered sleeve of claim 1, it is characterized in that being located at and contain aluminium groove (3), the big 0.2～0.5mm of tapered sleeve external diameter that the tapered sleeve external diameter at its cell body rear portion is more anterior than cell body on the tapered sleeve external diameter.
