И естное устройство дл выбивки -ишти ров валков стана холодной прокатки труб в ПК}чает установленный на noaqpoTHoK раме поршвевой пневмоципнщф двойного действи с двусторонним штоком, один конеа которого сна6)кен бойком, а друг( взаимодействует с механизмом удержани , причем механи .; удержани выполнен в иоде электромагнита.A conventional knockout device — the bits of rolls of the cold-rolling mill tube in a PC} is equipped with a double-acting piston pneumatic piston mounted on a noaqpoTHoK frame with a double-sided rod, one horse of which is sleeping6) made in the iodine of the electromagnet.

Отлична предпагаём го устройства соотоит в том, что механизм удержани njpeftставп ет собой двуплечий рычаг, ин конец которого сое/швен-с приводом поворота а другой выполнен в виде покового захвата, взаимодействующего с диском, установленным на другом конце штока Это позвол ет повысить надежность работы ста ка.The excellent assumption of the device is that the njpeft holding mechanism acts as a double-arm lever, the end of which is a coy / linkage with a rotation drive and the other is designed as an open grip that interacts with a disk mounted on the other end of the rod. This improves reliability a hundred ka

Устройство состоит из пфшневого пневм1 цилиндра 1 двойного действи с двусторонним штоком 2. Один конец штока снабжен бойком 3, а на другом насажен фигурный диск 4, наружна поверхность которого выпоThe device consists of a double-action pneumatic cylinder 1 of pfshnev1 with a double-sided rod 2. One end of the rod is equipped with a striker 3, and a figured disk 4 is mounted on the other, the outer surface of which

With the outer surface of the figured disk there is associated a holding mechanism, which is a double-arm lever 5, fixed on a support 6 j in series with a piston-type pneumatic cylinder; One end of the double-arm lever is connected with a rotational curve, which is an additional swinging pneumatic cylinder 7, and the other, made in the form of hooks 8, interacts with the disk 4.

Eice механизмы распоножены на рама 9 (см. фаг. 2). Рама с при(креш1енной к ней осью 1О установлена на упорный подшипник 11 и может поворачиватьс в горизонтальной плоскости относительно опорной платформы 12. Рама 9 вместе с платформой может также перемешатьс вдоль Л1шии нескольких ста, ков за счет установки последней на тележке 13Eice mechanisms are located on frame 9 (see phage 2). The frame with when (axle 1O cracked to it) is installed on the thrust bearing 11 and can rotate in a horizontal plane relative to the support platform 12. The frame 9 together with the platform can also be mixed along the length of several hundred, due to the installation of the latter on the trolley 13

the front position, the gauge-replacement device is located opposite the mill, and the mounting position 1 is set along the rolling axis. The end of the stem with the mounted disk 4 is set to the extreme left position until it stops. Pneumodipindor 7 by means of a double lever arm and a disk drive. -Holds the spherical distributor (not shown in the drawings), the output B of the pneumatic unit 1 reports: 1 trap. Then, by switching the air pressure and deflating the air pressure in the air. Responsibly ry 5. Under the action of water, the valve 4 is released from the pneumatic cylinder 7 by the collar about the axis on the support 6 and the pneumatic cylinder 1 strikes through the extension with its own extension gauges (extension and cap &rs; draws are not shown). Then the rod goes back to the extreme left vilification, snarling 5 ENTERS the contact with the surface of the disk 4, and the cycle repeats until you lose the caliber. The clogging is carried out in the rearmost frame of the cage as described above. According to the heading, the frame 9 is rotated 90 ° relative to the reference nnaiZ 12 and mixed either to the next camp or to be installed between the stalls, freeing the axis of rolling for the passage of the rub during rolling. The proposed device allows you to teach a change in the delay force over a wider range — to reduce overall sizes along the axis of the piston cylinder, and also to ensure the device moves along the line of several mills in those workshops where the front side of the mills with balance equipments , Claim I. Device for striking gauges of cold rolling mill rolls. tubes, including a double-acting piston-mounted pneumatic cylinder with a double-sided rod, one end of which is provided with a die, and a holding mechanism that interacts with the other end of the rod, so that, in order to improve the reliability of operation, the holding mechanism is a double-arm lever, one end of which is connected to the drive, and the other is designed as a hook, which interacts with a figured bottom installed at the other end of the rod.
