Abstract

The utility model relates to a dual-purpose cantilever ring type rolling machine, which can be used for rolling annular pieces without gaps or the single stands of straight pieces. The utility model is characterized in that the dual-purpose cantilever ring type rolling machine is composed of a machine body part, an adjusting device part for changing diameters and a driving device; the machine body part is provided with a front machine frame, a rear machine frame and four rollers; the four rollers are hung and fixed on the four shaft heads of four shafts, which extend out of the front machine frame; the front machine frame and the rear machine frame are cross-shaped; the rear machine frame is used to support an axle shaft and is connected with a retarding mechanism to form into a driving device; the front machine frame is connected with the rear machine frame to be fixed on a base. The utility model has the advantages of saving energy, small occupation area, single structure and one machine with multiple functions.

Description

Cantilever ring type rolling mill

The utility model relates to the improvement to rolling mill, be a kind of can rolling seamless annular element or the dual-purpose milling train of single stand---the cantilevered annular rolling mill of straight part.

At present, domestic rolling seamless annular element adopts rim and wheel special rolling mill, rolling rim or train wheel.The utility model cantilevered annular rolling mill is the dual-purpose rolling mill of single stand, and annular cast steel blank is without secondary operations, utilizes after the demoulding 750～950 ℃ of direct rolling seamless annular elements of temperature of itself, produces hubbed flange, also can be used for rolling straight part.

The utility model cantilevered annular rolling mill purpose provides the dual-purpose milling train of a kind of single stand can rolling seamless annular element and straight part, is used to make the accessory hubbed flange of the retort that chemical industry, printing and dyeing, pharmaceuticals industry use.

The utility model cantilevered annular rolling mill content Description:

The utility model cantilevered annular rolling mill is characterized in that it being to be made of body part, reducing adjusting device part and transmission device three parts, can be by microcomputer or manually control; Body partly is forward and backward frame, four rolls, and one of them is a concave roll, and one for compressing roll, two is the reducing roll in addition, four rollers are parastate, hang to fix on four axles that forebay leans out, on the spindle nose of driving shaft, compression axis and two multidiameter shafts, can be by microcomputer or manually control, hydraulic cylinder plays movable slider and rises, and compression axis drives and compresses roll, near concave roll, the hydraulic cylinder self-return, slide block, compression axis and compress roll and descend thereupon; The front and back frame is " ten " font, by afer bay supporting driving shaft, connects reductor, connecting axle, motor formation transmission device; Forward and backward frame is fastened on the basis by footing piece; Initiatively axis hole is arranged on the top of forward and backward frame " ten " font, be used to install bearing, driving shaft, connection concave roll, the vertically-guided slideway is arranged at the bottom, the thrust slide supporting compression axis, connection compresses roll, can move up and down in slideway, and two side arms is for installing the chute of reducing adjusting device, connect the reducing roll by multidiameter shaft, the reducing hydraulic cylinder is horizontally slipped.

The utility model cantilevered annular rolling mill is used for direct rolling hubbed flange, be equipped with microcomputer or manually control, directly rolling seamless annular steel part or directly part on the basis that electric furnace cast steel is arranged, but energy savings, calculate to produce 4000 tons of steel parts year, save coal-fired 1000 tons of milling trains and have that floor space is little, simple in structure, the characteristics of a tractor serves several purposes, also can save a large amount of equipment investments.

Embodiment:

Fig. 1 is cantilevered annular rolling mill overall structure figure;

Fig. 2 is a cantilevered annular rolling mill transmission diagram.

The utility model cantilevered annular rolling mill can be directly with after the foundry goods demoulding, and rolling without post bake, according to circle of 3 one-tenth, more fixing rotation pressurized makes seamless annular element at high temperature produce plastic deformation, reaches shape of product, dimensional requirement.

The utility model cantilevered annular rolling mill is achieved in that four rolls are concave rolls 1, compress roll 3 and two reducing rolls 6, wherein concave roll 1 is the active roll, all the other are the inertia roll, compress processed blank 17 by four rolls, after guiding, reducing, the adjustment, roll out qualified products.These four rolls are poised state, hang to fix on four axles that forebay leans out: on the spindle nose of driving shaft 2, compression axis 11 and two reducing roll shafts 4, and can be by microcomputer or manually control manipulation.Rise by 8 movable sliders of hydraulic cylinder 7, compression axis 11 drives and compresses roll 3 and descend thereupon and roll out product.Forward and backward frame is " ten " font, by afer bay 16 supporting driving shafts 2, connects reductor 13, connecting axle 12, motor 14 formation transmission devices; Forebay 9 is fastened on the basis by footing piece 10 with afer bay 16; On the top of forward and backward frame " ten " font initiatively axis hole is arranged, be used to install bearing 15, driving shaft 2, connect initiatively concave roll 1, the vertically-guided slideway is arranged at the bottom, slide block 7 supporting compression axises 11, and connection compresses roll 3, can move up and down in slideway.Two side arms connects reducing roll 6 for the chute of reducing adjusting device 5 is installed by reducing roll shaft 4, at microcomputer or with manual control reducing adjusting device 5, reducing hydraulic cylinder 8 is horizontally slipped, and treats that blank 17 is rolled into specification, and reducing roll 6 stops to slide.
