Abstract

An extension nozzle comprises a nozzle inner part, an end cap and an outer shell, wherein a clamp is mounted outside the outer shell, the end cap is mounted at the tail end of the nozzle inner part, the outer shell is in a split structure including an upper portion and a lower portion, and the nozzle inner part is arranged inside the outer shell. The extension nozzle has the advantages that the split structure includes the upper portion and the lower portion, the extension nozzle is composed of lining type inserts, the upper portion and the lower portion are interchangeable when the nozzle is used, the lining inserts are also changeable, a great deal of production cost and time can be saved, a rolled piece passing through the nozzle can be evenly cooled since cooling water and mist formed by heated water can be dissipated from the inside of the nozzle quickly, and thereby product quality is improved, operation resistance of the rolled piece in the water cooling process can be reduced, possibility of piling up of steel is reduced, and yield is increased.

Description

A kind of extension nozzle

Technical field

The utility model relates to the high-speed rod process technology, relates in particular to a kind of extension nozzle.

Background technology

Nozzle generally is to work under multiple different spray conditions and design by it, thereby selects the nozzle that is fit to needs for use, so that in use reach best cooling effect.The characteristic of nozzle is mainly reflected in the nozzle types of nozzle, shape that forms when promptly liquid leaves jet hole and its runnability; That its shape is divided into is fan-shaped, taper, fluid column stream, air atomizing, flat burner etc.The existing nozzle that is used for each iron company's high-speed rod will carry out strict process control to wire rod (being the product of high line) quality, is the important component part that the most frequently used wire rod is controlled process for cooling; But because some similar nozzle arrangements designs are unreasonable, exist that production cost is higher, difficult forming, heap steel probability be bigger, these all directly cause the reduction of production efficiency.

The utility model content

At above defective, the purpose of this utility model provides and a kind ofly saves production cost, moulding is simple, can reduce heap steel probability, make the extension nozzle of yield rate raising, with many deficiencies of solution prior art.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of extension nozzle, comprise by nozzle internals, end cap and shell body and forming, clip is installed in the shell body outside, the terminal end cap of installing of nozzle internals, described shell body is split type structure and is two parts up and down that described shell body inside is provided with the nozzle internals and lock by some internals pilot pins its bottom.

The beneficial effect of extension nozzle described in the utility model is: adopt split type structure to be divided into two up and down, and adopt the assembling of lined plug-in unit, during use not only up and down two interchangeable, and the lined plug-in unit is also replaceable; Help saving a large amount of production costs and time.When rolled piece from nozzle by the time, cooling water and water can be left from nozzle interior by the water smoke of thermosetting rapidly, make wire rod be able to even cooling, thereby promote product quality; Help reducing the running resistance of rolled piece in the water-cooled process, reduce the probability of heap steel, make yield rate improve.

Description of drawings

According to embodiment and accompanying drawing the utility model is described in further detail below.

Fig. 1 is the partial sectional view of the described extension nozzle of the utility model embodiment;

Fig. 2 is the external structure schematic diagram of the described extension nozzle of the utility model embodiment.

Among the figure:

1, nozzle internals; 2, end cap; 3, clip; 4, internals pilot pin; 5, loudspeaker tubular runner hole; 6, shell body.

The specific embodiment

Shown in Fig. 1-2, extension nozzle described in the utility model comprises by nozzle internals 1, end cap 2 and shell body 6 and forming, and described shell body 6 is split type structure and is two parts up and down that clip 3 is installed in these shell body 6 outsides; Described shell body 6 inside are provided with nozzle internals 1 and lock by some internals pilot pins 4 its bottom, and loudspeaker tubular runner hole 5 is offered at these inner flow passage two ends, nozzle internals 1 middle part respectively; The nozzle internals 1 terminal end cap 2 of installing.

Claims (1)

1. one kind is extended nozzle, comprise by nozzle internals (1), end cap (2) and shell body (6) and forming, clip (3) is installed in shell body (6) outside, the terminal end cap (2) of installing of nozzle internals (1), it is characterized in that: described shell body (6) is two parts for split type structure and about being, described shell body (6) inside is provided with nozzle internals (1) and lock by some internals pilot pins (4) its bottom.
