Description
Technical field
The utility model relates to a kind of metallurgical device, and more particularly, the utility model relates to a kind of metallurgical machinery device of processing wire rod.
Background technology
The rod-rolling mill of high-speed wire production line, subsequent configuration have the 3# flying shear, so that continuous rolled piece is implemented haircut, or in time will remain rolled piece shear cataclasm in case fault expansion when milling train and upstream device break down.And be that the accurate turn-out track in time of rolled piece is navigated to required rolling position or shears the position, key is to be close to 3# flying shear group steel pipe before can accurately and timely swing to required station with workpiece front end.For this reason, the linearity of dialling the steel pipe center line before the 3# flying shear is most important.
The conduit level butt joint form that traditional 3# flying shear is dialled steel pipe is: bearing, conduit, conduit rear support and the guiding of stirring the wire rod front portion are chewed before the conduit that connect to connect in regular turn, the conduit length overall is about 1175mm, diameter of bore is generally φ 30mm, and the conduit external diameter is generally φ 60mm.The guiding of dialling the steel pipe port of export chew and the conduit rear support between utilize the hexagon socket head cap screw of straight tube flange and M6*40 to be connected and fixed; Before and after bearing all be installed on the turn-out track support by cotter way and pin, brushless small machine and drive unit drive the turn-out track support and on dial the steel pipe swing, turn to different stations such as required shearing position, rolling position or cataclasm position thereby drive the wire rod front portion.
But long-term the use finds that tradition is dialled steel pipe and had following shortcoming:
1) because the needs of economical operation, Rolling Production all is that fast pace carries out continuously usually, therefore, in the continuous rolling production process, dial the motion of steel tube inner hole high speed owing to driven the rolled pieces such as wire rod that advance at the 3# flying shear by preceding working procedure, and the rolled piece temperature up to 1000 ℃ about, cause dialling the middle conduit flexural deformation gradually under high temperature and impact of steel pipe front and back bearing, usually, when rolling time continued 48 hours or more than, the deformation of guide tube that the 3# flying shear is dialled in the middle of the steel pipe can be all the more obviously with serious, so that dial the serious flexural deformation of steel pipe and can't drive rolled piece and accurately navigate to rolling position, cause heap steel fault thereby can cause rolled piece to depart from rolling guide groove from shearing the position conversion.
2) the long-term high speed of rolled piece in dialling steel pipe passed through the wearing and tearing that cause dialling the steel pipe inwall, add the influence that is subjected to rolled piece high temperature, microstructure and the mechanical strength of dialling the steel pipe material also can be affected, and this has aggravated the wearing and tearing of group steel pipe inwall, increase along with rolling tonnage, the wearing and tearing of dialling the steel pipe inwall are increasing, even it is worn out and cause heap steel accident to cause dialling steel pipe walls.
3) the 3# flying shear dial steel pipe by the front and back bearing and on cotter way and pin be installed on the turn-out track support, via brushless small machine and drive unit drive the turn-out track support and on the steel pipe of dialling carry out brute force and swing, because the powerful at a high speed turn-out track of drive unit impacts, dial the steel pipe export orientation chew with the conduit rear support between flange be connected with bolt and the phenomenon that gets loose can often occur, thereby directly the linearity of center line in the steel pipe is dialled in influence, cause turn-out track location inaccurate, the branch that rolled piece can hit passage after by haircut causes heap steel accident to plate.
Causing heap steel fault in case dial all distortion of steel pipe because of the 3# flying shear, is to guarantee ordinary production and stable operation, and whole production line just can only be shut down completely, change group steel pipe of distortion by the time after, could start shooting again.
Therefore the serial shortcoming that tradition is dialled steel pipe has not only influenced carrying out smoothly of producing, and has wasted valuable stocking and production time, and the distortion of changing dials steel pipe and can only scrap processing because of repairing also, has increased equipment operating cost.
Summary of the invention
Above-mentioned shortcoming at prior art, the purpose of this utility model is to provide a kind of cooled to dial steel pipe, it has following advantage: adopt cooling back installation to cool off dialling steel pipe, thereby strengthened group steel pipe at one stroke and resisted serial deformation ability, improved the hit rate of group steel pipe conversion station, reduce the high-speed rod-rolling mill equipment failure rate, prolonged the service life of group steel pipe, be convenient to promotion and implementation.
For this reason, technical solution of the present utility model is that a kind of cooled is dialled steel pipe, its be included as wire rod by and before the conduit that connect to connect in regular turn bearing, conduit, conduit rear support and the guiding of stirring the wire rod front portion chew, and described catheter jacket has water-cooled big envelope, is respectively equipped with the water supply connector and the water out adapter of cooling water at two of this big envelope.
The utility model is being dialled one section in the longest conduit of steel pipe, increase by one section water-cooled big envelope, pass to cooling water therein to being subjected to high temperature, at a high speed, impact, wearing and tearing the most very and the easiest deforming, rotten, the conduit of wearing and tearing cools off, thereby strengthened group steel pipe at one stroke and resisted serial deformation ability, both alleviated the directly influence of distortion of high temperature, also alleviated the destructive power of stocking high speed impact and wearing and tearing, substantially eliminated high temperature to dialling the rotten influence of steel pipe material, and the constant intensity of dialling steel pipe under the low temperature also be highly resistant to turn-out track impact for guiding chew with rear support between the influence that gets loose that is connected with set bolt of flange, obviously, the resistance capacity to deformation that the utility model is dialled steel pipe to be increased can improve the hit rate of swing shearing, thereby reduce the high-speed rod-rolling mill equipment failure rate, prolong the service life of dialling steel pipe, and simple in structure, be convenient to promotion and implementation.
Chew for further guaranteeing to lead and rear support between lower temperature, the bigger bonding strength of flange and set bolt place, thereby improve whole non-deformability, the utility model comprises that following concrete structure improves:
