Description

(54) МОТАЛКА(54) CHANGER

Изобретение относитс к области обработки металлов давлением,а именно к производству мелкосортного проката, и может быть использовано дл намотки последнего.The invention relates to the field of metal forming, namely, the production of light-gauge steel, and can be used for winding the latter.

По основному авт. св. 664710 известна моталка дл мелкосортного проката, содержаща намоточный барабан , состо щий из ведущего диска с буртиком, шарнирно закрепленного на ведущем диске намоточных штырей и , подъемного стола, неподвижную.Обечайку , выполненную со спиральным пазом , и уклсщчик витков 1 .According to the main author. St. 664710 is a known coiler for small-section rolled products containing a winding drum consisting of a leading disk with a flange hinged on the driving disk of the winding pins and, a lifting table, stationary. The guard made with a spiral groove and the turntable of the coils 1.

Недостатком моталки вл етс то, что задний конец каждого раската сматываетс в бунт без нат жени , центробежными и упругими силами он отдел етс от тела бунта, образу 2-4 и более вращаю1цихс витка, диаметр которых больше наружного бунта и равен диаметру окружакщей намоточное пространство обечайки. Во врем торможени барабана эти витки опадают вниз, искажа форму бунта.The disadvantage of the winder is that the rear end of each roll coils into a riot without tension, centrifugal and elastic forces it separates from the body of the riot, forming 2-4 or more turns of the coil, the diameter of which is larger than the outer riot and equal to the diameter of the shell that surrounds the winding space . During the deceleration of the drum, these coils fall down, distorting the shape of the riot.

Недостатком этой моталки вл етс и то, что буртик диска преп тствует укладчику витков подавать прокат на нижнюю часть намоточных штырей. Таким образом, возникает незаполненнал часть намоточного пространства, куда периодически срываютс витки проката, создава зону хаотической укладки. Неправильна геометрическа форма бунтов затрудн ет их обв зку , транспортировку и термообработку.The disadvantage of this winder is that the disc shoulder prevents the turn stacker from rolling to the lower part of the winding pins. Thus, an empty part of the winding space arises, where the rolled coils periodically break, creating a zone of chaotic laying. The improper geometric shape of the riots makes them difficult to tie, transport, and heat treat.

Целью изобретени вл етс улучшение геометрии бунта.The aim of the invention is to improve the geometry of the riot.

Указанна цель достигаетс тем, This goal is achieved by

10 что моталка снабжена установленным между намоточными штыр ми и неподвижной обечайкой параллельно оси намоточного барабана холостым прижимным роликом с приводом его пере15 мещени в радиальном направлении, а на ведущем диске и подъемном столе выполнен кольцевой профилированный паз, образованный двум наклонными стенками, при этом стенка, удален20 на от оси намоточного барабана на большее расто ние, наклонена к его оси на угол 10-15°, а друга стенка на угол 50-80°.10 that the winder is provided with a single idle pressure roller mounted between the winding pins and the fixed shell parallel to the axis of the winding drum and driven 15 in the radial direction, and on the drive disk and the lifting table there is an annular shaped groove formed by two inclined walls, the wall being removed20 on the axis of the winding drum by a larger plant, inclined to its axis by an angle of 10–15 °, and the other wall by an angle of 50–80 °.

Моталка снабжена направл квдими ро25 ликами, установленными в спиральном пазу неподвижной обечайки.The coiler is equipped with guides mounted in the spiral groove of the fixed shell.

Холостой прижимной ролик в верхней части снабжен ребордой.The idle pressure roller in the upper part is equipped with a flange.

Claims

The idler roller is made sectional. FIG. 1 shows a winder, type x: top; in fig. 2 shows section A-A in FIG. one ; in fig. 3 - idle pressure roller sectional design, cut. The winder contains a winding drum consisting of a driving disc 1 with a shoulder 2, hinged on the drive disk of the winding pins 3, a lifting table 4, a fixed shell 5, along the surface of which a spiral groove b is made, and the drive jf of the winding ring 7 turns. On the lever 8, is equipped with an pneumatic cylinder 9 as a drive; an idle pressure roller 10 is installed parallel to the axis of the winding drum; in the upper end part it is equipped with a flange 11 to prevent the upper coils from breaking off the body of the riot. On the drive disk 1 and the lifting table 4, an annular profiled groove 12 is formed, which is formed by two inclined walls, while the wall, more remote from the axis of the winding drum, is inclined to its axis by an angle of 10-15 °, and the other wall is at an angle of 50-80 °, respectively. The annular groove 12 may also have a bottom formed by a plane, perpendicular to the axis of rotation of the drum. The sharp edges of the annular shaped groove may be rounded. Inside the spiral groove, to reduce rolling friction, guide rollers 13 can be installed. The idle pressure roller 10 can be made of sections 14 to reduce the moment of inertia during acceleration. The offered winder works as follows. Before rolling the car, the drive dis 1 is rotated at a given speed, the stacker 7 turns occupies a middle position (opposite the entrance to the spiral groove b), the roller 10 is retracted from the drum. Leaving the stacker 7 turns, the front end of the car enters the spiral groove 6 and along the guides of the mouths 13, which are installed to reduce the friction of the car (especially large profiles) against the bottom of the spiral groove, is fed to the bottom of the annular profiled groove 12. Outer ( with respect to the axis of rotation) of the surface of the groove, due to its inclination, hold the front end of the car from the exit of the groove. After this, the rolling, fond of friction forces, envelops the winding pins 3 and overwhelms them, so that it slides along the inner conical surface of the annular grooved groove, rises to the level covered by the laying and goes out of the spiral groove. The drive of the stacker 7 is turned on and the rolling winding with tension on the winding pins is carried out. . 10-15 seconds before the end of the winding, the roller 10 is moved to the riot and, in the process of further winding, they are in the pressed state. At the end of the winding, the drive disk 1 is brake t, the rear end of the rolling roller 10 is clamped to the riot, after the winding drum is installed, the J-O roller is retracted from the riot, the lifting table raises the riot above the level of the winding pins 3, from where the latter is removed. Thanks to this design of the winder, it is possible to wind the riots of an improved geometrical shape, since the last turns are tightly attached to the body of the riot, and the diameter of the former does not exceed the diameter of the latter. This makes it possible to wrap them with existing machines, reduces their injury during transportation, and also eliminates the need to cut the turns separated from the riots before being loaded into the through-furnaces. The use of this winder for winding the rolling that goes through in the passing-through furnaces, allows you to do without cutting on each riot 4-6 fluff turns, i.e. to keep from culling about 75 kg of metal (on average for the assortment) for one riot. .
