Abstract

A side looper comprises an entry guide for directing a longitudinally moving long product into an arcuate path, an exit guide for receiving the product exiting from the arcuate path, and inner and outer guide walls arranged between the entry and exit guides. The guide walls are adjustable between mutually spaced closed positions fixing the curvature of the arcuate path, and open positions allowing the curvature of the arcuate path to either increase or decrease.

Description

The side loop lifter
Technical field
The present invention relates generally to has the two-wire of producing rod, bar etc. or multi-thread continuous hot-rolling mill, and particularly relates to and provide a kind of at the improved side loop lifter along the type of place, the selected location employing of the roll line of this milling train.
Background technology
Compare with band and other similar flat articles, be intended to comprise round rod, bar etc. like the term " long goods " that is adopted herein.And, be intended to limit the arch deflection of goods like the term " kink " that is adopted herein.
Rolling operating period in producing the continuous hot-rolling mill of long goods, next the transfer rate of the common goods that leave from the upstream rollers frame is different from the inbound pacing of downstream rollers frame subsequently.In order to handle this velocity variations, between continuous roller frame, adopt repeater sometimes.Repeater is through introducing the direction that kink changes goods in about 180 ° goods.Yet the shortcoming of this layout is that the relatively large area of mill floor must be used to adapt to the repeater kink.
Also adopt the side loop lifter in order between continuous roller frame, to introduce kink.The side loop lifter typically generates less than about 120 ° less kink, and therefore compares mill floor space compact more and need be less with repeater.In the side loop lifter, at first, through forming kink, and then, surpass the inbound pacing of downstream frame like the fruit product transfer rate that frame is left from the upper reaches around fixing arch guiding wall guiding goods, then allow the curvature of kink to increase.Yet, suppose that the transfer rate that surpasses upper reaches frame owing to the inbound pacing of downstream frame causes the speed imbalance, the reducing of compensation kink curvature receives the obstruction of the fixed guide wall of loop lifter, thereby causes forming the tension force of not expecting in the goods.
The present invention has solved this problem through following side loop lifter is provided, that is: this side loop lifter is designed in order to the increase of the curvature that adapts to kink and reduces.
Summary of the invention
Side loop lifter according to the present invention is designed to through along the route guidance goods of arch and in the long goods of lengthwise movement, form kink.The side loop lifter comprises and is used for the guide portion of leaving that goods are supplied to the entering guide portion of arched path and are used to receive the goods that leave from arched path.Interior guiding wall and outer guiding wall are arranged in the entering guide portion and leave between the guide portion.Guiding wall can the spaced closed position of the fixing curvature of arched path and allow the curvature in path to increase or the open position that reduces between regulate.
Description of drawings
To these and other characteristic and advantage of the present invention be described in further detail with reference to accompanying drawing at present, wherein:
Fig. 1 is the schematic diagram of employing according to the part of the continuous hot-rolling mill of loop lifter of the present invention;
Fig. 2 is the enlarged drawing of one of them loop lifter shown in Fig. 1, and wherein guiding wall is in its closed position; And
Fig. 3 is the view that is similar to the guiding wall of illustrating of Fig. 2 in being shown in an open position.
The specific embodiment
At first with reference to Fig. 1, the last rolling mill of two-wire hot-rolling mill is drawn with 10.Two goods lines 12---typically are and have the pole section of the diameter of 30mm at least---and leave roller frame 10, and before the roller frame that gets into two single line tandem mills 16, are conducted through according to side loop lifter 14 of the present invention.
With reference to Fig. 2 and 3, can see that each loop lifter 14 is in order to guide the long goods 12 of lengthwise movement along the path P of arch in addition.Get into guide portion 18 goods are imported in the path P, and leave guide portion 20 and receive the goods that leave from this path.Interior guiding wall 22 and outer guiding wall 24 are arranged in the entering guide portion and leave between the guide portion.Inwall 22 is divided into and gets into section 22a and leave section 22b, said entering section 22a with leave section 22b as being installed to pivotally on the base structure 28 at 26 places, and as be connected to piston cylinder type linear actuators 32 at 30 places.Outer guiding wall 24 is divided into similarly and gets into section 24a and leave section 24b, said entering section 24a with leave section 24b as being installed on the base structure pivotally at 34 places, and as be connected to linear actuators 35 separately at 38 places.
Linear actuators 32,38 is as operating means, and this operating means is used for---as shown in Figure 2---adjusting between and open position is---as shown in Figure 3---with the spaced closed position of guiding wall 22,24 in the curvature of fixed route P.When guiding wall was adjusted to its open position, goods were freely followed the arched path that increases curvature, as by dotted line P A-cPoint out, perhaps follow and have the arched path that reduces curvature, as at P dThe place points out.
In operation, before goods get into loop lifter, guiding wall 22,24 is adjusted to its closed position, with the curvature of fixed route P.Then, goods direct in the path, derive along this route guidance and through leaving guide portion 20 via getting into guide portion 18.Along with goods expose from leaving guide portion, guiding wall 22,24 is adjusted to its open position, so that continue along the path and when loop lifter is advanced, allow the curvature of path of navigation to increase as stated or reduce at goods.
Goods in case from get into that guide portion 18 is left and simultaneously goods still getting into guide portion and leaving between the guide portion 20 and advance, just can guiding wall 22,24 be adjusted to its closed position, so impel tail end to get back to the arched path P of original rights.Therefore the side loop lifter is prepared rapidly in order to accept the front end of next approaching goods, and it makes that required gap minimizes between the billet of being processed by milling train.
According to preceding text, those skilled in the art will recognize, loop lifter of the present invention not only can adapt to the transfer rate of upper reaches frame 10 surpass speed imbalance between the frame under the situation of inbound pacing of downstream frame 16 (as in Fig. 3 with P A-cThe path of navigation curvature drawn increases), can also adapt to the speed imbalance that transfer rate that inbound pacing by downstream frame 16 surpasses upper reaches frame 10 causes (as in Fig. 3 with P dThe path of navigation curvature of drawing reduces).Therefore, in the later case, avoided in goods, forming the tension force of not expecting.
The description of front has been illustrated with explanation the present invention and has been not meant to and limited.Those skilled in the art can expect combining other remodeling of the described embodiment of spirit of the present invention and purport.For example, a this remodeling can comprise translational adjustment rather than the pivotal adjustment of guiding wall 22,24 between its open position and closed position.Therefore, scope of the present invention should only limit with reference to accompanying claims and equivalent thereof.
