Description

Four/five cutting guide devices

Technical field

The utility model is a kind of guide and guards that is used for rolled wire or bar in the steel rolling continuous-rolling system, especially relates to a kind of key equipment that wire rod or bar are carried out cutting along its length of being used for.

Background technology

At present, the guide and guards that the steel rolling continuous-rolling system is used morely mainly contains two cuttings or three cutting guide devices, after being installed in milling train, the rolled piece of wire rod or bar is earlier through becoming rolled piece in parallel after the roll cutting, rolled piece in parallel is again by cutting guide device, rolled piece longitudinally rived into independently rolled piece of two or three under the effect of slitting wheel.

The two present cuttings or the defective of three cutting guide devices are: two/three Cutting guides, once a rolled piece can only be cut into two or three bars or wire rod, and efficient is lower.

The utility model content

The purpose of this utility model is to propose a kind of four/five cutting guide devices, once can be rolling four or five bars or wire rod.Distance between the slitting wheel wedge point of forward and backward cutting wheels can be adjusted at any time as required, to satisfy the cutting needs of different size rolled piece in parallel; In the material-dividing groove rear end sub-material deflector roll is installed, replaces with rolling and slide, can effectively avoid steel bonding, heap steel accident to take place; In addition, the utility model adopts broached-tooth design at the faying face of pressing plate and casing assembly, in conjunction with more firm.

The technical solution of the utility model is as follows:

Four/five cutting guide devices include the casing assembly, base, the guide and guard mouth of casing assembly front end, the material-dividing groove of rear end, the water route assembly on the casing assembly; It is characterized in that being equipped with on the described casing assembly forward and backward cutting wheels, forward and backward cutting wheels are formed by upper and lower two slitting wheels, and its forward and backward cutting wheels have two kinds of structures:

(1), two cutting wedges are arranged on the slitting wheel of preceding cutting wheels, distance is passed through for holding two rolled pieces in parallel between the two cutting wedges, and a cutting wedge is arranged on the slitting wheel of back cutting wheels, aims at the intermediate ribs band position of two rolled pieces in parallel, constitutes four Cutting guides.

(2), two cutting wedges are arranged on the slitting wheel of preceding cutting wheels, distance is passed through for holding three rolled pieces in parallel between the two cutting wedges, and two cutting wedges are arranged on the slitting wheel of back cutting wheels, aims at two muscle band positions of three rolled pieces in parallel, constitutes five Cutting guides.

Described four/five cutting guide devices is characterized in that described base both sides respectively are equipped with eyelet bolt, and the bolt upper end is equipped with a pressing plate, nut is installed on the pressing plate is pressed on the casing assembly, and pressing plate bottom surface and casing assembly faying face adopt broached-tooth design.

Described four/five cutting guide devices is characterized in that the rear end of described material-dividing groove is equipped with the sub-material deflector roll, the position of sub-material deflector roll between rolled piece in parallel.

Described four/five cutting guide devices, each slitting wheel that it is characterized in that described forward and backward cutting wheels all is to be installed on the casing assembly by eccentric shaft, one end of eccentric shaft is fixedly connected with worm gear, former and later two worm shafts are installed on the sidewall of casing assembly, two worm screws that direction of rotation is opposite are installed, the worm gear engagement on corresponding with it the respectively eccentric shaft of two worm screws on each worm shaft on each worm shaft.

By the rotary worm axle, realize the stepless adjustment in the gap between upper and lower slitting wheel wedge point.

Pass through the shape and the angle of the cutting wedge that designs for guaranteeing rolled piece in parallel to be rived after rolled piece is through the cutting wedge on the forward and backward cutting wheels slitting wheel on the slitting wheel of forward and backward cutting wheels between the cutting wedge smoothly apart from holding rolled piece in parallel.

Compare with prior art, the utlity model has tangible advantage:

1, rolling efficiency obviously improves.Because four/five Cutting guides, once can rolling four/five bars or wire rod, with respect to two/three Cutting guide technology, energy savings, save equipment investment, improve output, efficient can improve nearly one times.

2, guide and guard structure advanced person, principle novelty, use are reliably.Because two groups of slitting wheel structures before and after the utility model has adopted, make rolled piece in each cutting process, only be equivalent to through one time three cutting, and then again through one time two cutting or three cuttings, and owing to set up the sub-material deflector roll in the material-dividing groove rear end, replace slip with rolling, rolled piece is difficult for taking place steel bonding heap steel phenomenon, improves rolling stability.。

3, maintenance is convenient, easy to use.Slitting wheel adopts eccentric shaft to install, and adjusts the distance between the eccentric shaft by worm gear, worm mechanism; In the operation of rolling, can adjust the relative position between the slitting wheel wedge point as required at any time; Operating maintenance is all very convenient.

4, install firmly.Because the faying face of pressing plate bottom surface and casing assembly adopts broached-tooth design, it is more reliable that guide and guard are installed.
