Abstract

The invention relates to a special machine tool for manufacturing large-sized steel thin-wall flanges. The special machine tool is characterized in that a transmission shaft is vertically arranged and fixed on the central position of an upper beam through a bearing; a disc is arranged in a guide key slot of the transmission shaft positioned below the upper beam through a guide key; a connecting plate is fixedly arranged on the tail end of the lower part of the transmission shaft; two guide rails are symmetrically and fixedly arranged at the bottom of the disc; slide blocks are respectively arranged on the guide rails; a conical grinding wheel is arranged on a rolling wheel shaft; both ends of the rolling wheel shaft are respectively articulated with the slide blocks and one end of the connecting plate; two or more than two top pressure oil cylinders are fixedly arranged at the bottom of the upper beam in a uniformly distributing way; a plane bearing is arranged between the disc and the top pressure oil cylinders; a transmission system is fixedly connected with the upper part of the transmission shaft; a mould is fixedly arranged on the upper plane of a base; and a core mould is arranged in a central blind hole of the mould.

Description

A kind of large-sized steel thin-walled flange is made special purpose machine tool
Technical field
The present invention relates to a kind of flange and make special purpose machine tool, particularly a kind of large-sized steel thin-walled flange is made special purpose machine tool, belongs to flange and makes the special equipment technical field.
Background technology
Flange is the operating conduit coupling of pipeline in petrochemical industry, electric power, water conservancy and other industry, and its use has a large capacity and a wide range; What at present, device fabrications such as general employing steel plate cutting assembly welding or employing forging, punching press formed on the manufacture method of flange.In above-mentioned manufacture method, adopt the method for steel plate cutting assembly welding, it is low to have stock utilization, the labour intensity height, and the low shortcoming of labor productivity, forge and adopt, though the manufacture method of pressing equipment has higher labor productivity, equipment investment is bigger, simultaneously, owing to adopt the necessary supporting special mould of above-mentioned equipment, this has not only strengthened manufacturing cost simultaneously further, and the versatility of production is also relatively poor, in addition, adopt the method for forging punching press to make flange, though production efficiency improves, compare with the batch and the existing labor productivity of producing, still have the leeway of further raising.
Summary of the invention
The objective of the invention is to: provide a kind of large-sized steel thin-walled flange to make special plane, overcoming existing large-sized steel thin-walled flange makes, owing to adopt the steel plate cutting assembly welding, existing: stock utilization is low, the defective that labour intensity is bigger, simultaneously, also be existing in order to overcome existing employing forging pressing equipment: equipment interoperability is relatively poor, equipment investment is bigger, and the not high defective of productivity ratio.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of large-sized steel thin-walled flange is made special purpose machine tool, it be by 1, base; 2, roof pressure oil cylinder; 3, plane bearing; 4, disk; 5, column; 6, put the beams in place; 7, bearing; 8, transmission system; 9, power transmission shaft; 10, mould; 11, core; 12, gusset piece; 13, taper rolling wheel; 14, slide block; 15, guide rail; 16 feather keys; 17, the roll extrusion wheel shaft is formed, it is characterized in that: by base, column and upper beam are fixedly connected into the framework of " mouth " sub-shape, power transmission shaft vertically is fixed on the upper beam center by bearing, described disk is installed in the guiding keyway of the following power transmission shaft of putting the beams in place by feather key, described gusset piece be fixed on power transmission shaft lower end, install and fix two guide rails symmetrically in the bottom of disk, a slide block respectively is installed above the described guide rail.Slide block has the free degree of sliding along guide rail, one taper rolling wheel is installed on the roll extrusion wheel shaft, the two ends of roll extrusion wheel shaft respectively with slide block, one end of gusset piece is hinged, described roof pressure oil cylinder constitutes more than on two or two, the roof pressure oil cylinder is fixed on the bottom of upper beam in uniform way, is provided with a plane bearing is installed between disk and roof pressure oil cylinder, and the top of described transmission system and power transmission shaft is connected and fixed.Described mould is fixed on the last plane of base, and core is placed in the central blind hole of mould.
The course of work of the present invention is: the material that at first utilizes the steel plate strip, utilize equipment such as veneer reeling machine the material of strip to be rolled into the blank of round barrel shape, educate in the hole at the center that the blank of drum dress is placed on mould, core is placed the blank hole of round barrel shape, core with blank compacting be fixed on mould above, when just starting working, the piston of roof pressure oil cylinder is in topmost, thereby slide block is moved to center position along guide rail, cone angle between the taper rolling wheel is diminished, so that make the taper rolling wheel stretch into the oral area of drum blank, under the situation of transmission system drives power transmission shaft rotation, then the taper rolling wheel is on the one hand around the rotation of roll extrusion wheel shaft, simultaneously, around the power transmission shaft revolution, when the downward roof pressure of roof pressure oil cylinder piston bar, then disk moves down, slide block outwards moves, thereby make the cone angle between the taper rolling wheel become big, and press the oral area that grinds blank to expand outwardly, until arriving complete flange product.
Beneficial effect: the present invention is owing to adopt technique scheme, overcome and showed in the existing large-sized steel thin-walled flange manufacturing, owing to adopt the steel plate cutting assembly welding, existing: stock utilization is low, the defective that labour intensity is bigger, simultaneously, it is existing also to have overcome existing employing forging pressing equipment: equipment interoperability is relatively poor, equipment investment is bigger, and the not high defective of productivity ratio.
