Abstract
A combined drive roller of the cold rolling mill for rolling ring is composed of an annular base with internal installation hole, and a slotted mould consisting of semi-circular left and right slotted moulds with molding slot on their circumferences. The internal circumference of said slotted mould is in contact with the external circumference of said annular base and fixed to the latter via screw bolts.
Description
Technical field
The present invention relates to the driven roller of cold looping type rolling mill.
Technical background
Driven roller is one of vitals on the cold looping type rolling mill, and the rolling type groove on the driven roller has determined the cross sectional shape of looping mill rolling spare.When the looping mill rolling spare of rolling different cross section shape, often need to shut down the driven roller that the back integral replacing has different rolling type grooves, this process generally needs 2-3 hour; In addition and since each driven roller only corresponding a kind of rolling type groove, when the ring of the rolling different cross section shape of needs, just must make driven roller again, this just needs long fabrication cycle, and causes the waste of driven roller making material; After the driven roller that more renews, also need to roll through debugging and examination, these steps have all seriously reduced production efficiency and have improved production cost.
Summary of the invention
At the deficiency more than the existing cold looping type rolling mill driven roller, the object of the present invention is to provide a kind of easy for installation, roller in composition type actuator in cold looping type rolling mill efficiently.
To achieve these goals, the present invention has adopted following technical scheme to be: roller in composition type actuator in cold looping type rolling mill, and it comprises driven roller pedestal 1, type channel mould piece; Driven roller pedestal 1 is an annular, is installing hole 6 in the driven roller pedestal 1; It is characterized in that: type channel mould piece is made up of right slotted mould 2, left slotted mould 5, right slotted mould 2, left slotted mould 5 are semi-round ring shape, be equipped with type groove 8 on the periphery of right slotted mould 2, left slotted mould 5, the inner headed face of right slotted mould 2, left slotted mould 5 contacts with the periphery of driven roller pedestal 1 and is fixedly connected by bolt 4.
The periphery of described driven roller pedestal 1 is provided with positioning boss 7, is equipped with on the inner headed face of right slotted mould 2, left slotted mould 5 and positioning boss 7 corresponding grooves.
The present invention adopts said structure, has following beneficial effect: when the ring of the rolling different cross section of needs, do not need overall pulling down driven roller again, and just change the type channel mould piece on the driven roller pedestal 1; This changes rolling type channel mould piece process fast approximately only needs 20-30min, easy for installation, quick.Because the effect of the positioning boss 7 on the driven roller pedestal, after the channel mould piece of more remodeling, just can continue rollingly with readjusting looping mill hardly, the accuracy height with regard to obviously having shortened the time of replacing, has improved production efficiency and economic benefit like this.

The specific embodiment
Be example with D56G90 cold-rolling mill model type cold looping type rolling mill below, and the invention will be further elaborated in conjunction with the accompanying drawings.
The former driven roller of D56G90 type cold looping type rolling mill such as Fig. 4, shown in Figure 5, excircle dimension are D0=Φ 217mm, and interior circle is of a size of D1=Φ 120mm, and thickness B 0=is 50mm.
Through improving roller in composition type actuator in cold looping type rolling mill such as Fig. 1, the Fig. 2, shown in Figure 3 after designing.Former driven roller is divided into driven roller pedestal 1 and type channel mould piece (right slotted mould 2, left slotted mould 5) two parts,
As Fig. 1, Fig. 2, shown in Figure 3, roller in composition type actuator in cold looping type rolling mill, it comprises driven roller pedestal 1, type channel mould piece, driven roller pedestal 1 is an annular, in the driven roller pedestal 1 is installing hole 6, the inner headed face of driven roller pedestal 1 is provided with locating slot 3, and during use, driven roller pedestal 1 fixes (being fixed by locating slot 3, locating piece) by the main shaft on installing hole 6 and the cold looping type rolling mill; Type channel mould piece is made up of right slotted mould 2, left slotted mould 5, right slotted mould 2, left slotted mould 5 are semi-round ring shape, be equipped with type groove 8 on the periphery of right slotted mould 2, left slotted mould 5, the inner headed face of right slotted mould 2, left slotted mould 5 contacts with the periphery of driven roller pedestal 1 and by bolt 4 (hexagon socket head cap screws, totally 16, respectively be 8 on right slotted mould 2, the left slotted mould 5) fixedly connected.The periphery of described driven roller pedestal 1 is provided with positioning boss 7, is equipped with on the inner headed face of right slotted mould 2, left slotted mould 5 and positioning boss 7 corresponding grooves.The axial location of type channel mould piece is guaranteed by the positioning boss on the driven roller pedestal 17.
The structure of driven roller pedestal 1 of the present invention such as Fig. 6, Fig. 7, shown in Figure 8.Excircle dimension is D3=Φ 180mm, and positioning boss 7 is of a size of B1=3mm, H=2.5mm, fillet R1=1mm, all the other size constancies former driven roller of D56G90 type cold looping type rolling mill (be).The medial surface G of periphery F and positioning boss is the installation contact-making surface, needs correct grinding.The manufacture method of type channel mould piece:
The annular blank of (1) forging type channel mould piece: the blank of type channel mould piece adopts the gropping of forging billet with the pedestal same material, size such as Fig. 9, shown in Figure 10, outside diameter D4=Φ 240mm, interior circular diameter D5=Φ 160mm, thickness B 1=60-70mm;
(2) turning processing: as Figure 11, shown in Figure 12, turning processes inside and outside disc, rolling type groove and side, and wherein inside and outside disc stays correct grinding surplus 0.5-1mm, and the work type groove stays correct grinding surplus 0.5-1mm, side D stays correct grinding surplus 0.5-1mm, locating surface C stays correct grinding surplus 0.5-1mm, the diameter D6=Φ 187mm of detent, and promptly the height of groove is 3.5mm, be higher than the positioning boss 7 height H=2.5mm (as shown in Figure 8) on the driven roller, D7=Φ 180mm, L=50mm, L1=16mm;
(3) process each bolt hole, successively each bolt hole on the processing type channel mould piece;
(4) vacuum heat is quenched in vacuum heat treatment furnace, tempering, to reduce deflection;
