Description

The soft metal wire rod odd-shaped cross section continuous cold rolling device of band suspension supplemental support

Technical field

The utility model relates to a kind of continuous cold rolling device of making the band suspension supplemental support of profiled-cross-section groove with the soft metal wire rod, it is to can be applicable to soft metal wire rod (comprising low-carbon (LC) dish round steel, copper or aluminium wire) to make core-spun yarn, the metal rolled device on metal powder heart yearn or the flux-cored wire automatic assembly line.

Background technology

Existing with the manufacturing of soft metal wire rod core-spun yarn, metal powder heart yearn or the cold rolling unit of flux-cored wire automatic assembly line profiled-cross-section, its architectural feature is to adopt a pair of top and bottom rolls, top and bottom rolls is contained in respectively on the top and bottom rolls axle, and the top and bottom rolls axle is a cantilever structure, rolled piece rotates through top and bottom rolls nips rolled piece, and enter roll and be rolled into profiled-cross-section, then through just put buffer-oriented live can guide roller, enter down one roll and be rolled.Be used to produce the soft metal of core-spun yarn or flux-cored wire, usually adopt the following mild steel wire rod of  6.5mm or above-mentioned other wire rods, and the Special-Shaped Surface that rolls out is shaped as V-shape, for guaranteeing that product is qualified, require to guarantee V-shape cross section two arm symmetries, and two arm thickness equate, and above-mentioned cantilever design under the effect of large deformation roll-force, can produce very big rebound amount, cause the uneven thickness of V-shape cross section two arms etc., the rolled piece of this two arm uneven thickness etc. enters down the road roll by overhead buffer-oriented kink roller and easily produces rolled piece and reverse, simultaneously because overhead buffer-oriented kink version, cause between the roll-box, the length of rolled piece that dangles is short and rigidity is big, is unfavorable for guiding, like this in the operation of rolling, rolled piece breaks away from roll easily, and what influence was produced normally carries out.

The specific embodiment

The utility model provides a kind of soft metal wire rod odd-shaped cross section continuous cold rolling device with the suspension supplemental support, it is to can be applicable to the soft metal wire rod to make core-spun yarn, on metal powder heart yearn or the flux-cored wire automatic assembly line, it is characterized in that, this device comprises the roll-box of some series connection, a pair roller 1 of type with holes, 3 are individually fixed on bottom roll axle 2 and the topping roll axle 4 by connecting expansion set, 4 on bottom roll axle 2 and topping roll axle are installed in the roll-box, one end of bottom roll axle 2 is connected with transmission mechanism, and be provided with a cover suspension support mechanism 5 so that topping roll axle 4 and bottom roll axle 2 are linked together in another termination of topping roll axle 4 and bottom roll axle 2, between roll-box, also set up inverted cylinder kink buffer-oriented device 6.

But topping roll axle 4 is a floating structure.

Suspension support mechanism 5 links to each other with the termination of topping roll axle 4 with bottom roll axle 2 by rolling or sliding bearing, and the part that suspension support mechanism 5 links to each other with topping roll axle 4 is a floating structure, can be in company with topping roll axle 4 up-down adjustment.

Be provided with the rolling directive wheel 7 that connects with cylinder in the inverted cylinder kink buffer-oriented device 6.

Inverted cylinder kink buffer-oriented device 6 is provided with displacement transducer.

As shown in Fig. 1 and Fig. 2, the soft metal wire rod odd-shaped cross section continuous cold rolling device of the band suspension supplemental support that the utility model is related comprises the roll-box of some series connection, a pair roller 1,3 of type with holes is individually fixed on bottom roll axle 2 and the topping roll axle 4 by connecting expansion set, 4 on bottom roll axle 2 and topping roll axle are installed in the roll-box, and an end of bottom roll axle 2 is connected with transmission mechanism.Connecting by the swelling cover of roll and roll mandrel realizes that this coupling method can transmit big moment, make again regulate more convenient.And topping roll axle 4 is a floating structure, as required the distance between up-down adjustment and the fixing bottom roll axle 2.

Beam type roll mandrel for avoiding adopting because of at present because the effect of roll-force produces very big inhomogeneous strain, causes the in uneven thickness of rolled piece two side arms in the operation of rolling, influence product quality.In the cold rolling continuous apparatus of the related band suspension supplemental support of the utility model, axle head at topping roll axle 4 and bottom roll axle 2 is provided with suspension supplemental support 5, on the suspension supplemental support 5 two bearings is arranged, link with two roll axle heads respectively, the bottom roll axle head is contained in the bearing below the suspension supplemental support 5, and the topping roll axle head is contained in the bearing above the suspension supplemental support 5.Upper bearing (metal) is contained in the removable slide block, can carry out up-down adjustment.Usually after top and bottom rolls regulates, suspension supplemental support 5 is loaded onto, regulated the metal (upper in the suspension supplemental support 5 again, lock after regulating.Like this, just eliminate the uneven thickness of the rolled piece two side arms that causes owing to the strain of roll mandrel in the operation of rolling, thereby guarantee product quality.

Wire rod carries out the profiled-cross-section cold continuous rolling, and the key that can production normally be carried out is to compensate the error of mill speed between the roll-box, promptly prevents to pile the reliable guiding that the appearance of drawing the steel phenomenon and rolled piece enter roll.As shown in Figure 3, in the cold rolling continuous apparatus of the related band suspension supplemental support of the utility model, between roll-box, set up the inverted cylinder meeting of living buffer-oriented device 6, be provided with the rolling directive wheel 7 that connects with cylinder in the inverted cylinder kink buffer-oriented device 6, by cylinder kink buffer-oriented device is inverted guide roller 7 is strengthened to the vertical range of bottom roll 2, thereby make the length of rolled piece lengthening that dangles, rigidity reduces, and formed cornerite on the bottom roll can strengthen rolled piece and enter roll the time, make rolled piece obtain reliably guiding and produce continuously to enter roll.The related inverted cylinder buffer-oriented device of the utility model is to provide tensile force by the compressed air cylinder, and the rolled piece by guide roller 7 is all tightly adhered in any position on it, to reach the good guidance purpose.

In addition, the related inverted cylinder kink buffer-oriented device of the utility model can be worked as the length lengthening that makes the rolled piece that dangles between the roll-box when mill speed produces error between the roll-box or be shortened, so just affect guide roller 7 to move up and down along kink 9 together with steam-cylinder piston 8, and the displacement transducer that is provided with in steam-cylinder piston 8 can change displacement signal into the signal of telecommunication and pass to control system, regulate the mill speed of roll-box again by drive mechanism by control system, to remedy the mill speed error between the roll-box, prevent to pile the appearance of drawing the steel phenomenon, continuous rolling is stablized carried out.Simultaneously, the related inverted cylinder kink buffer-oriented device 6 of the utility model can also solve the contradiction of space anxiety between the roll-box that is caused owing to additional suspension supplemental support 5.
