Abstract
The utility model aims to provide a pressure-reducing conical sleeve of a high-speed wire rolling machine, which comprises a conical sleeve head part, a conical sleeve shell and a plurality of expansion slots. The conical sleeve head part and the conical sleeve shell are connected into a whole, and the conical sleeve shell is uniformly provided with three expansion slots so that small interference fit of the conical sleeve and a roller ring is changed into small clearance fit. The wear of the conical sleeve and the roller ring is reduced greatly during plugging, the service life of the conical sleeve and the roller ring is prolonged, the replacement frequency is reduced, the high-speed wire production efficiency is increased, and the production cost is decreased.
Description
Technical field
The utility model relates to high-speed rod and produces element part field, particularly a kind of high-speed wire mill decompression type tapered sleeve.
Background technology
Collars is the core parts that high-speed rod is produced, and the quality and the output of product is had important effect, and tapered sleeve then is used for locking collars, and collars is enclosed within outside the tapered sleeve, and tapered sleeve then is enclosed within on the roll mandrel.In the high-speed rod activity in production, collars needs often to change, and just changes once in the shortest 10 hours; Changing once in the longest 2 days, generally all is replacing in 1 day, changes collars and normally adopts the hydraulic pressure plug; Pressure can reach 35mpa during insertion, and pressure can reach 70mpa when extracting, because tapered sleeve is that slight interference cooperates with roll collar inner hole; Thereby repeatedly the dismounting meeting causes the wearing and tearing of tapered sleeve and collars, causes there is not the magnitude of interference, makes tapered sleeve reduce service life or scraps; The frequent replacing of consequent tapered sleeve then can reduce the efficient that whole high-speed rod is produced, and increases production cost.
Summary of the invention
The purpose of the utility model provides a kind of new high-speed wire mill decompression type tapered sleeve, can adapt to replacing frequent in the production process, increases its service life, improves high-speed rod production efficiency, reduces production costs.
The technical scheme of the utility model is: a kind of high-speed wire mill decompression type tapered sleeve is provided, comprises the tapered sleeve head, tapered sleeve housing and expansion slot.
Said tapered sleeve is an iron and steel material quality, is cylindrical structure, and tapered sleeve head and tapered sleeve housing are connected as a single entity.
Said tapered sleeve head has the outer tongue of twice, links closely mutually with miscellaneous part.
Said tapered sleeve housing is connected with the tapered sleeve head, and is cylindrical, and the outside is the smooth face of cylinder, and enclosure interior is an inverted cone-shaped structure, and more near the tapered sleeve head, interior diameter is just more little.
Said expansion slot has three roads, is evenly distributed on the housing of tapered sleeve, and the expansion slot slit is 2mm.
The usefulness of the utility model is: three road expansion slots evenly are set on the tapered sleeve housing; Make between tapered sleeve and the collars to cooperate and change into little matched in clearance by slight interference; The inverted cone-shaped structure of tapered sleeve enclosure interior makes tapered sleeve contact with the roll mandrel conical surface; Thereby make tapered sleeve expand, utilize little matched in clearance to lock collars.
Description of drawings
Fig. 1 is the utility model sketch map, and dotted line top is divided into cutaway view.
The specific embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
As shown in the figure, the utility model is cylindrical shape structure of steel product parts, and there is the outer groove of twice tapered sleeve head (1) outside; Tapered sleeve housing (2) is connected with tapered sleeve head (1), and is cylindrical, and the outside is the smooth face of cylinder; Enclosure interior is an inverted cone-shaped structure, and more near the tapered sleeve head, interior diameter is just more little; Expansion slot (3) has three roads, is evenly distributed on the tapered sleeve housing (2), and the expansion slot slit is 2mm.
Tapered sleeve is enclosed within on the roll mandrel; Because expansion slot (3); The inner surface of tapered sleeve housing (2) fully contacts with the roll mandrel conical surface, and the inner back taper contact-making surface of tapered sleeve housing (2) receives the extruding of roll mandrel, and then expands; Be enclosed within before this on the tapered sleeve because collars is former, the expansion of tapered sleeve more can be locked collars through little matched in clearance.
Slight interference with respect to original old pattern tapered sleeve cooperates; The little matched in clearance that the utility model brought is more simple, can significantly reduce the wearing and tearing of tapered sleeve and collars, the service life of lifting tapered sleeve and collars in the process of plug; Reduce and change number of times, thereby improve the efficient that high-speed rod is produced.
More than specifying is the preferred embodiment of the utility model; This embodiment is not the claim in order to restriction the utility model; Allly do not break away from equivalence enforcement or distortion, the improvement etc. that the utility model is done, all should be included within the protection domain of the utility model.
