Abstract
The utility model relates to a special internal conduit for a sectional bent pipe guiding and guarding device of a high-speed wire rod spinning machine. A guiding and guarding straight pipe is made of carbon tool steel, and a lining is made of hard alloy; the lining is cold-pressed or hot-pressed in the guiding and guarding straight pipe; the upper end and the lower end of the lining are provided with arc-shaped edge parts; and the middle part of the guiding and guarding straight pipe is provided with the hard alloy lining. The utility model has the advantages that the guiding and guarding pipe is an internal pipe body, and a working surface is made of the hard alloy lining to maximize the functions of two materials. When the abrasion of the hard alloy lining exceeds difference, only the lining needs to be replaced, and the guiding and guarding body is retained, so the cost and the material consumption are reduced, the guiding and guarding precision can be ensured for a long time, and the conduit is particularly suitable for the requirement of continuous production and makes the production efficiency greatly improved.
Description
Technical field
The utility model relates to a kind of inner catheter of using on a kind of wire rod Laying head, particularly a kind of special-purpose inner catheter of high-speed rod Laying head guide and guards.
Background technology
The wire rod Laying head changes over the output of dish circle by rotating at a high speed with straight-line wire rod, be installed in the direct workpiece contact of spirality spinneret on the Laying head and finish this work, the effect of bend pipe is that wire rod is imported Laying head accurately, do not change the direction of its craspedodrome, guarantee to finish smoothly to weave silk.As the key equipment on the main rolling line under the situation that Laying head runs up, the high rhythm of wire production, high-speed, high-temperature, the impulsive force, the frictional force that make guide and guards be subjected to are bigger than other parts, conduit is generally shorter service life, as frequent replacing, cause the decline of whole production line overall efficiency, to improving linear velocity and improving production capacity and constituted and have a strong impact on.A large amount of scenes is detected data and is shown, under the situation of running, the speed of high-speed rod can reach 120m/s, and the linear velocity of high-speed rod is controlled at 105-110m/s under the normal condition, and the temperature of work is generally at 850-950 ℃ in the Laying head.In the process, pipe friction produces heat in workpiece and the Laying head, adds the workpiece self heat owing to run up, and moment contact area temperature rising causes that the spinneret subregion sharply changes, and makes material hardness descend, and very easily causes wearing and tearing.And the inner catheter material in the Laying head segmentation bend pipe guide and guards is a cast steel, and cast steel is worked under hot conditions and cooling repeatedly, can produce phenomenons such as oxidation and growth usually.Make that conduit is yielding, easy to wear, warpage, crack even break that cause reduce service life, production efficiency descends, and increases labour intensity and maintenance load, be prone to scuffing during rolling wire rod finished product in enormous quantities.Cause the significant wastage of material, increased production cost.
Summary of the invention
At the deficiency that above-mentioned technical problem exists, the purpose of this utility model provides the special-purpose inner catheter of a kind of high-speed rod Laying head segmentation bend pipe guide and guards.
The technical solution of the utility model is as follows:
The special-purpose inner catheter of a kind of high-speed rod Laying head segmentation bend pipe guide and guards, the guide and guard straight tube adopts carbon tool steel to make, and liner adopts carbide alloy to make.Cold pressing in the inside of guide and guard straight tube or hot pressing has liner.
The two ends up and down of described liner are provided with circular arc limit portion.
The beneficial effects of the utility model are: the guide and guard straight tube is interior pipe body, and working face adopts the carbide alloy liner that two kinds of materials can both be played a role to greatest extent.Only change this liner when overproof when the carbide alloy liner weares and teares, reduced cost and reduce material consumption, also can guarantee the guide and guard operating accuracy for a long time, be particularly suitable for the serialization production requirement, production efficiency is improved greatly thereby keep the guide and guard body.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 guide and guard straight tube; 2 liners.
The specific embodiment
As shown in Figure 1, guide and guard straight tube 1 adopts carbon tool steel to make, and liner 2 adopts carbide alloy to make.Guide and guard straight tube 1 is compressed together with the method that liner 2 usefulness are colded pressing.The two ends up and down of described liner 2 are provided with circular arc limit portion.
Flow process is as follows: will be placed on the press bench by the good guide and guard straight tube 1 of required size car in advance, guide and guard straight tube 1 is selected the carbon tool steel material for use, as the 45# steel.Then putting into carbide alloy liner 2 in guide and guard straight tube 1 colds pressing or hot pressing.
Claims (2)
