Description
Technical field
[0001] belongs to the pipe bending technique field, exactly relate to the technology that bends of small curvature radius tube panel.
Background technology
The film-type water-cooling wall components is all arranged in the station boiler of routine, be square, constitute the shell of boiler by surrounding four walls.The structure of fin panel casing is: pipe+flat bar iron+pipe+flat bar iron+... Be welded into tube panel.In the film-type water-cooling wall components, the crooked structure of tube panel is all arranged at its both walls bottom and Hou Qiang top.
The tube panel manufacture craft of conventional belt warp architecture: be with pipe+flat bar iron+pipe+flat bar iron+... Weld drawing requirement and become tube panel.The appearance and size of conventional tube panel: wide～2000mm, length～15000mm;
The welding procedure that the straight weld of pipe and band steel is adopted is: machinery welds automatically, and it is with tube panel handling bending machine extremely in a row, carries out bend pipe in a row.The advantage of this technology: appearance of weld is good, and welding quality is high, and speed of welding is fast, and labour intensity is low.The general configuration of bending machine in a row: its lathe bed is similar to one section channel-section steel, and the channel-section steel opening makes progress, and the both sides of channel-section steel are equivalent to the both sides of lathe bed, and middle dress welding steel plate is the platform that is used to deposit tube panel.The width of channel-section steel has just determined to bend the width of tube panel; Two gear wheels have two holes on the gear, the center at gear; Be used to install the core rod that bend pipe is used; Another is used to install the roller-way that bend pipe is used below centre bore, the centre distance in two holes is exactly: the radius of the bending radius+pipe diameter of tube panel+roller-way; According to core rod (main shaft) and roller-way that the bending radius of drawing tube panel is processed, the two ends with them are fixed on two gear wheels respectively, are loaded on an end (top) of lathe bed simultaneously together; The other end (below) at lathe bed is installed a reductor, and pinion is arranged on the reductor, by the power of reductor output, drives hinge wheel through chain and rotates.In the time of bend pipe, as long as tube panel is put on the core rod (main shaft) and roller-way platform of bending machine in a row, start reductor, hinge wheel just rotates.Because core rod is at the center of gear wheel, tube panel is clipped in the middle of core rod and the roller-way, and its rotation is exactly that roller-way is pushing away tube panel comparatively speaking, and is along core rod, that tube panel is crooked.
In the market, make the tube panel of band warp architecture, the bending machine in a row of use all is such structure.But it has a very big defective, just can not process for the tube panel of small curvature radius exactly.Because bending radius is directly proportional with core rod (main shaft) (be that bending radius is more little, the core rod on the equipment is just more little), its rigidity can not overcome the crooked power of tube panel.So conclusion that draws: bending machine in a row in the market can not be processed the tube panel of small curvature radius.
For the tube panel that occurs small curvature radius on the structure in boiler, if adopt following manufacture craft:, on general bending machine, bend shaping at first with single pipe; The single bend pipe that will bend shaping has again bent the band steel of shaping respectively in their middle scarfweld.Will bring following fatal shortcoming: inefficiency, (wanting single bend pipe, single curved band steel, the artificial again band steel that embeds, artificial welding); Appearance of weld is poor, (because artificial welding, the shaping of welding is shaped less than mechanical welding); Labour intensity is big; Poor product quality, distortion is big; Manufacturing cycle is long; And can not adopt this scheme.
Summary of the invention
The power that the utility model provides the rigidity of core rod axle can overcome the tube panel bending, thereby realization ability bend pipe in a row, 180 ° of a kind of small curvature radius tube panel that the ability quality is good, efficient is high, the small curvature radius tube panel is processed in suitable mass production bend device.
The technical scheme that the utility model is taked:
180 ° of the small curvature radius tube panel bend device, comprise the core rod that bends dependence, and its scheme is: be welded to the tube panel that width as required constitutes mutually by band steel between small diameter metal tube whose, be inserted in to bend and rely between core rod and the roller-way; Said core rod is that two vertical parallel are settled fastening hinge wheel, and two sprocket wheels respectively have two corresponding circular holes, and a circular hole is being inserted the core rod axle movingly and constituted core rod at the center; Another circular hole is being inserted the roller-way that the rigidity circular shaft constitutes in central lower; That the roller-way limit has is one parallel with the roller-way tangent plane, width is the wide channel steel shape screen road of tube panel; Gap between core rod axle and roller-way is the thickness of tube panel loose fit; Have between the reductor of hinge wheel and driving drive chain around; Screen has on the road core rod axial compression of moving along chute to live mobile device; Mobile device is lived in said core rod axial compression, is the approximate cuboid of a flat formula, highly is about the twice of core rod shaft diameter; The cuboid head is the circular arc that can comprise half core rod axle and the driving fit of semicircle axle, and the top, inclined plane at nearly 30 ° of angles is arranged; The rear end is a triangle protrusion, and the protruding end is the translation impetus, is connecting to push down drive unit; Being close to the below of shielding the road is the mobile platform that is contained on the platform chute, and mobile platform and platform drive unit link.
Good effect behind enforcement the utility model is:
Since the utility model be the level of bend pipe core rod and above, that sets up a core rod axle pushes down mobile device (being commonly called as indenter device), this indenter device can move forward and backward.The fixed platform that former bend pipe is used makes the platform that can move forward and backward into.Indenter device moves on to core rod when curved when tube panel rises, and gives power-assisted of core rod, mainly is the holding capacity that reaches horizontal direction downwards, be used for overcoming 0 °～120 ° bend pipe process core rods receive upwards and the power of horizontal direction.When tube panel is bent to 120 °, because core rod is changed by force direction, can bend 180 ° in order to ensure tube panel in addition, indenter device is removed (this indenter device is inoperative, influences bending of 180 ° of tube panels owing to indenter device is higher than core rod simultaneously) backward.Platform moves forward under the core rod.Assist core rod to bear downward power, finally accomplish 180 ° the process that bends.
The utility model is owing to taked these measures; It is little and the practical problem of the poor rigidity that produces increases rigidity for the core rod of bend pipe to have overcome core rod diameter that small curvature radius uses, thereby reaches the tube panel that can bend small curvature radius to 180 °; Solve problem, satisfied the production needs.
