Detailed description of the invention
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.First it should be noted that, the utility model is not limited to following detailed description of the invention, the spirit that those skilled in the art should embody from following embodiment is understood the utility model, and each technical term can be done the most wide in range understanding based on Spirit Essence of the present utility model.In figure, same or analogous member uses the same reference numerals to represent.
A kind of winding pipe assembly for metal wire rod hot rolling line of the present utility model, can be applicable to various wire rod steel grades at a high speed, reduce the wearing and tearing of interior bend pipe under high temperature production state, to reduce its replacement frequency and to improve wire spinning tonnage and product surface quality.
As shown in Figures 2 to 4, the winding pipe assembly for metal wire rod hot rolling line of an embodiment of the utility model, be arranged between pinch roll and spinneret (not shown) front end, comprise shell 1 ', pressing plate 3 ', shell 1 ' is for being the long box body of spill of radian, it is formed with arc inner chamber body, and pressing plate 3 ' is removably fixedly mounted on shell 1 '; Wherein said arc inner chamber body is divided into the multistage radian being evenly distributed, and also comprises: multiple vessel segments 6, embed on each section of radian limit being evenly distributed, and between each vessel segment 6, there is gap 6a; Multiple guide groove joints 4, are fitted in respectively in vessel segment 6; And compressed air joint 5, be arranged on shell 1 ' and go up and stretch in inner chamber body.The shell 1 ' of described spill is made up of stainless steel material.Pressing plate 3 ' is fixedly mounted on shell 1 ' by multiple bolt 3a.As shown in Figure 4, one end endoporus 4a of guide groove joint 4 is horn mouth, and guide groove saves 4 outer surface middle parts and offers a groove 4b.Guide groove joint 4 is by powdered metallurgical material, and for example tungsten carbide is made.
When the above-mentioned winding pipe assembly for metal wire rod hot rolling line of the present utility model can effectively be avoided producing class wire rods such as high-carbon steel, elbow internal wall wear extent is bigger than normal, and easily produce such wire coiling surface tear and cause product quality accident, project organization is simple, it is easy, easy to maintenance to install, long service life, can shorten the online replacing time to improve operating rate.
Further illustrate details and the effect of above-mentioned winding pipe assembly structure each several part of the present utility model below in conjunction with accompanying drawing, so that clearer understanding feature of the present utility model and advantage.
Winding pipe assembly is the guider (being radian type) between Laying head and the pinch roll of Laying head front end on the production line of hot-rolling metal wire rod, existing structure is as shown in Figure 1: the outer box of camber is that shell 1 is that conduit 2 combines with an inner bend pipe, be used for changing roll line angle and play guide effect, because this guider is radian shape, some wire rod steel grade is in high speed, under high temperature production state, in guider, bend pipe 2 weares and teares huge, have influence on wire surface quality and this device replacement frequency. for this reason, be vessel segment 6 by the structure of guider inside bend pipe 2 being redesigned for sectional inner sleeve saves, then guide groove joint 4 is embedded in vessel segment one by one, and can accomplish local replacing, configure compressed air joint 5 simultaneously, guarantee that guide groove saves 4 internal coolings, cleaning action, thereby improve high-carbon steel grade wire spinning tonnage and product surface quality.Specifically, the winding pipe assembly of the utility model design, comprises following characteristics:
Winding pipe assembly is a kind of damascene structures of radian concave shape, spill shell 1 ' material adopts stainless steel, in radian cavity, be divided into multiple sections so that multiple vessel segments 6 are embedded in is evenly distributed on each section of radian limit, in the middle of each vessel segment, there is the gap 6a of for example 5mm;
In the present embodiment, the external diameter 35mm of guide groove joint 4, endoporus 20mm, one end endoporus is horn mouth, and the outer surface middle part of guide groove joint 4 has a groove 4b, for example dark 2.5mm of long 10mm.Guide groove joint 4 adopts such as tungsten carbide of powdered metallurgical material, the trade mark: ZY33.A compressed air joint of shell 1 ' upper installation of winding pipe assembly extend in its inner chamber body.
The box body of winding pipe assembly of the present utility model once drops into, can extend this device service life, shortening will be changed the time online, elbow internal wall wear extent phenomenon bigger than normal while solving class wire rods such as producing high-carbon steel, and easily produce such wire coiling surface tear and cause product quality accident problem, simple in structure, install easily, easy to maintenance, can improve operating rate.
Upper in an application example, the guide groove joint that size dimension is equal to is installed in winding pipe assembly radian cavity spy, and be embedded in bend pipe cavity location when on bar by guide groove recess position, arrange one by one by order, guide groove joint horn mouth direction be towards importer to, at winding pipe assembly lower end, compressed air joint being installed, is finally that the exceedingly high bolt of pressing plate pins spill winding pipe assembly with cover plate.
When work, under high-speed rolling, on horizontal roll line, wire rod enters full folder DANILEI pinch roll, enter at a high speed subsequently the utility model winding pipe assembly inner region that radius is 1800mm, in the guide groove joint 4 of wire rod in bend pipe cavity, pass, and by be arranged to force to carry out break-in in radian guide groove joint in cavity, due in break-in process, wire rod and guide groove joint endoporus top forced friction, forming section wire surface iron scale and part sparrow sheet, be retained between guide groove joint endoporus or guide groove joint in gap, easily produce heap steel or scratch, for this reason, a compressed air joint 5 is set in winding pipe assembly lower end, make to use in the height operation of rolling compressed air save by guide groove between gap, the endoporus that pressure-air is entered to guide groove joint 5 foreign matter such as descale is urged out from winding pipe assembly two ends, and import smoothly DIANILEI Laying head and carry out lopping collection.Because the utility model modern design is reasonable, simple in structure, easy for installation, workable, solve in former winding pipe assembly that bend pipe is easy to wear, surface tear technical barrier, meet the normal production requirement of wire rod rolling.
Should be understood that those skilled in the art can make various changes or modifications the utility model after having read above-mentioned instruction content of the present utility model, these equivalent form of values fall within the application's appended claims limited range equally.
