According to the flange manufacturing machine tool, a base is provided; the base, stand columns and an upper beam are fixedly connected so as to form a square frame; a drive shaft is vertically arranged at a central position of the upper beam through a bearing; a disk is arranged in a guide key groove of the drive shaft under the upper beam through a guide key; a connecting plate is arranged at the tail end of the lower part of the drive shaft; two guide rails are symmetrically and fixedly arranged at the bottom of the disk; slide blocks are arranged on the guide rails; a conical rolling wheel is arranged on a rolling wheel shaft; two ends of the rolling wheel shaft are respectively connected with one ends of the slide blocks and the connecting plate; two jacking oil cylinders are uniformly arranged the bottom of the upper beam; a plane bearing is arranged between the disk and the jacking oil cylinders; a drive system is connected with the upper part of and the drive shaft; a die is arranged on an upper plane of the base; and a core die is arranged in a central blind hole of the mould.
Description
Technical field
The present invention relates to a kind of flange manufacturing machine tool, particularly a kind of novel steel flanges produces lathes, and belongs to flange and makes the special equipment technical field.
Background technology
Flange is the operating conduit coupling of pipeline in oil, chemical 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 in the manufacturing of flange.In above-mentioned manufacture, adopt the mode of steel plate cutting assembly welding, have that stock utilization is low, labour intensity is high, and the low shortcoming of labor productivity, forge and adopt, though the manufacture 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 the cost of making further, and simultaneously, the versatility of production is also relatively poor, in addition, this employing is forged the mode of punching press and is made flange, though production efficiency improves, but compare with production lot and existing labor productivity, still have the leeway of further raising.
Summary of the invention
The objective of the invention is to: provide a kind of novel steel flanges to produce lathes, overcoming existing large-sized steel 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 novel steel flanges produces lathes, it is by flange manufacturing machine tool one base to be arranged, base, column and upper beam are fixedly connected into the framework of " mouth " sub-shape, power transmission shaft vertically is installed in the upper beam center by bearing, disk is installed in the guiding keyway of the following power transmission shaft of putting the beams in place by feather key, gusset piece is installed in the lower end of power transmission shaft, and the bottom of disk installs and fixes two guide rails symmetrically, and slide block is installed on the guide rail; One taper rolling wheel is installed on the roll extrusion wheel shaft, and the two ends of roll extrusion wheel shaft are connected with an end of slide block, gusset piece respectively; Two roof pressure oil cylinders are installed in the bottom of upper beam in uniform way, between disk and the roof pressure oil cylinder plane bearing are installed, and transmission system is connected with the top of power transmission shaft, and mould is installed on the last plane of base, and core is placed in the central blind hole of mould.
Operation principle of the present invention is: the material that at first utilizes strip under the steel plate, 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 round barrel shape 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 existing steel flanges on making, 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.
