Description
Technical field
The utility model belongs to the bending of metal tube, relates in particular to the bending apparatus that the thick-walled metal long tube is bent into many elbow-shaped pipe.
Background technology
It is one of important measures of blast furnace longevityization that cast steel cooling wall substitutes cast-iron cooling wall, also is the developing direction of blast furnace furnace wall cooling.But up to the present cast steel cooling wall does not also have extensive use, and very important reasons is exactly that cast steel cooling wall exists many problems to be difficult to solve on manufacturing technology, and wherein bending of the cooling water pipe of cooling wall is exactly a great difficult problem.The cooling water pipe wall thickness of cast steel cooling wall, complex-shaped, be many elbows serpentine, the bending radius of elbow is little, the diameter ratio value of the bending radius of elbow and pipe is less than 2, must bend with whole thick-walled seamless steel pipes according to technological requirement to form, and the centre does not allow to exist welding point.At present, also be not suitable for bending the swan neck system of cast steel cooling wall water pipe, general bending machine can only be used to bend that elbow is few, the pipe of simple shape.
At present, the preparation method of cooling water pipe is that elder generation manually bends the pipe heating, with welding manner section of a pipe, an elbow is welded one by one and is linked to be integral body again.Its defective is that cooling water pipe shape, the scale error of this method splicing is big, the elbow out-of-shape, and crooked position is crushed nearly all in various degree, can't guarantee the cross sectional shape of pipe, welding point is many, and weldquality is difficult to guarantee, stays many hidden danger for the later process of cooling wall product manufacturing, have a strong impact on pipe water flowing and cooling performance, cause the unstable product quality of cooling wall, yield rate is low, and pipe bending labour intensity is big, efficient is low, the energy consumption height.
Summary of the invention
In order to overcome the deficiency that prior art exists, the purpose of this utility model provides the bending apparatus of a kind of blast furnace cast steel wall cooling water control, solves the difficult problem that cooling water pipe bends, and improves product percent of pass and working (machining) efficiency; Reduce labour intensity, energy savings; Bending quality is good, for the following process of making cast steel cooling wall creates conditions.
The bending apparatus of blast furnace cast steel cooling wall cooling water pipe comprises the fuselage that cabinet and workbench constitute, and power set are fixed in the cabinet, is characterized in stretching out in the circular hole of output shaft by the workbench setting of power set, and facing head is fixed on the output shaft; The facing head centre of gyration is established the shaping mechanism of band briquetting roller, and facing head card one side is established band and rolled the bending roll machine structure of curved wheel and the hold-down mechanism of band contact roller; The workbench correspondence is established clamp mechanism.During bend pipe pipe at briquetting roller, roll under the effect of curved wheel, contact roller and clamp mechanism, finish the bend pipe operation along with facing head rotates.
The utility model further improves: described power set, comprise cycloidal planetary gear speed reducer, and connect worm reducer by yielding coupling, be separately fixed at the cabinet bottom, worm reducer is established the output shaft of band keyway, and facing head is fixed on the output shaft by flat key.Power set provide the power of bend pipe.
Described builder, the facing head centre of gyration is established the central shaft concentric with output shaft, and the briquetting roller kink is on central shaft, and matched in clearance can freely be rotated on central shaft; Briquetting roller wheel rim one side is established a crescent breach, solves centre wheel and just withdraws from the ring bend prescription.
Described bending roll machine structure is established little axle on the slide block of bending roll machine structure, roll curved wheel kink on little axle, and is free to rotate; Slide block is fixed on rolling in the curved chute that facing head establishes by screw rod and nut.Adjust screw rod and nut, slide block can move forward and backward in rolling curved chute, adapts to the needs that bend various calibers and elbow specification.
Described hold-down mechanism is established little axle on the slide block of hold-down mechanism, the contact roller kink is on little axle, and is free to rotate; Slide block is fixed on compressing in the chute that facing head establishes by screw rod and nut, adjusts screw rod and nut, and slide block can move forward and backward in compressing chute, adapts to the needs that bend various calibers and elbow specification.
Briquetting roller, roll curved wheel and contact roller all is the mould of bend pipe, its wheel face circumferencial direction is all established semicircle annular groove, and its parameter all adapts with the diameter of bend pipe and the diameter of elbow.
The deck of described clamp mechanism is fixed on the workbench, and it is corresponding that position and rolling mechanism are installed the position of pipe, and semicircle wedge and " V " shape wedge are set in the deck, is used to realize the clamping to pipe; Wedge adopts less gradient to improve self-locking performance, and both cooperations provide powerful chucking power and frictional force during bend pipe, have both guaranteed that clamping was reliable, and the function that keeps the pipe cross sectional shape is arranged again, and it is flat to prevent that retaining part from being squeezed.
During bend pipe, according to the specification of pipe and the size of elbow, select the briquetting roller of corresponding specification, contact roller is bent wheel with rolling, and kink is loaded onto the pipe that will process on central shaft and the little axle of two slide blocks respectively, with wedge pipe is firmly clamped again.Start button, power set are given output shaft with transmission of power, output shaft drives facing head and rotates, curved wheel is rolled in drive and contact roller moves in a circle along briquetting roller, because semicircle and " V " shape wedge that pipe one end is arranged on the workbench are firmly fixing, under the crunch effect of rolling curved wheel, pipe is rolled curved, under the cooperation of contact roller, pipe is pressed together in the semicircle annular groove of middle briquetting roller tightly, the elbow shape of formation rule.By that analogy, up to all elbows of processing, form required many elbows serpentine cooling water pipe.
Compared with prior art, advantage is;
1, solves the difficult problem that long-term insoluble whole thick walled steel tube bends many elbows serpentine pipe of small curve.
2, the cooling water pipe that bends meets technological requirement, steady quality, and the yield rate height has been created good condition for making the high-quality cooling wall.
3, labour intensity reduces greatly, raises the efficiency energy savings.
