Изобретение относитс к автоматизации листовой штамповки и может быть использовано дл подачи полосового и ленточного материала в рабочую зону пресса.The invention relates to the automation of sheet metal forming and can be used to feed strip and strip material into the working area of a press.

Известно устройство дл подачи полосового и ленточного материала в рабочую зону пресса, содержащее установленные в корпусе при помощи валов верхний подс1ющий валок и нижний по- Ю дающий валок, св занные между собой зубчатой передачей. На валу нижнего подающего валка закреплено зубчатое колесо, периодически вход щее в зацепление с зубчатым сектором, смокти-15 рованным в корпусе на индивидуальном валу, несущем обгонную муфту, включающую в себ ведомую часть и ведущую часть, на которой закреплена ( или выполнена за одно целое с ней) шее- 20 терн , вход ща в зацепление с другой шестерней, приводимой в движение от-подвижной части пресса {1.A device for feeding the strip and tape material into the working area of the press is known, which comprises an upper driving roller and a lower feed roller, which are interconnected by a gear train, mounted in the housing with the help of shafts. A gear wheel is fixed on the shaft of the lower feed roll, periodically engaging with the toothed sector, mounted in the housing on an individual shaft, carrying an overrunning clutch, which includes the driven part and the leading part on which it is fixed (or made in one piece with it) a neck - 20 tern, which engages with another gear, set in motion from the movable part of the press {1.

Однако известное устройство имеет сложную кинематическую схему, а это 25 вносит переменную ошибку в шаг подачи , вл ющуюс результатом погрешностей в кинематической цепи.However, the known device has a complex kinematic scheme, and this 25 introduces a variable error in the feed pitch resulting from errors in the kinematic chain.

Целью изобретени вл етс повышение точности шага подачи. . 30The aim of the invention is to improve the accuracy of the feed pitch. . thirty

Поставленна цель достигаетс тем, что в устройстве дл подачи полосового и ленточного материала в рабочую зону пресса, содержащем установленные в K.opnyde на валах верхний и нижний подающие валки, св занные между собой зубчатой передачей, обгонную муфту, включающую в себ ведомую часть и ведущую часть, несущую шестерню , зубчатый сектор, приводимый в качательное движение, обгонна муфта установлена на валу одного из подающих валков, ее ведома часть Жестко св зана с этим валом, а зубчатый сектор закреплен в корпусе с возможностью взаимодействи с шестерней.This goal is achieved by the fact that in the device for feeding strip and tape material into the working area of the press, the upper and lower feed rollers connected to each other by a gear drive, an overrunning clutch comprising a driven part and a driving gear, are installed in K.opnyde on the shafts. the gear carrier part, the toothed sector, which is rocked, the overrunning clutch is mounted on the shaft of one of the feed rollers, its knowledge is rigidly connected to this shaft, and the toothed sector is fixed in the housing with the possibility of Procedure with gear.

На чертеже схематически изображено предлагаемое устройство, общий вид.The drawing schematically shows the proposed device, a General view.

Устройство дл подачи полосового и ленточного материала в рабочую зону пресса содержит верхний подающий валок 1 и нижний подающий валок 2, устанровленные при помощи валов соответственно 3 и 4 в корпусе 5. На концах валов 3 и 4 установлены вход щие в зацепление между собой шестерни б и 7 и тормоза 8 и 9.The device for feeding the strip and tape material into the working area of the press contains an upper feed roll 1 and a lower feed roll 2, mounted with shafts 3 and 4, respectively, in housing 5. At the ends of shafts 3 and 4, gears b and b are inserted. 7 and brakes 8 and 9.

Claims

The shaft 3 with the help of bearings 10 and I is installed in moving vertical sliders 12 and 13, respectively, equipped with a mechanism for moving and adjusting, press roller 1 to roll 2, made in the form of a screw 14 and spring 15. Sliders 12 and 13 move in the direction of Kitsim 16 and 17. The shaft 4 is mounted on the housing 5 on the bearings 18 and 19. On the shaft 4, a clutch is mounted, including the driven part 20, rigidly mounted to the shaft and the driving part 21, the non-oblique gear 22. Parts 20 and 21 of the overrunning clutch are interconnected by the role of a coke 23. In The housing 5 with the help of bearings 24 and 25 has a shaft 26 supporting the toothed sector 27, which engages with the gear 22. The wheel 26 is driven from the moving part of the press (not shown). The diameter D2 of the lower feed roll and the diameter D of the overrunning clutch part 21 are in the ratio niit. The device for feeding the strip and tape material into the working area of the press works as follows. The shaft 26 is driven into reciprocating motion, which, in turn, drives the gear sector 27 into motion. The gear sector 27 rotates through the gear 22 the leading part 21 of the overrunning clutch and rotates it by a given angle proportional to the length of the feed step. The drive part 21, through the rollers 23, brings the driven part 20 of the coupling into a reciprocating motion. The driven part 20 rotates the shaft 4 together with the lower feed roller

2. The shaft 4 through the gears 6 and 7 rotates the shaft 3 with the upper feed roller 1; When the shaft 26 is rotated to the other side (the toothed sector 27 rotates the coupling part 21 through the gear 22, and the rollers 23 are wedged and do not transmit the rotation of the driven part 20. The feed rolls 1 and 2 do not rotate and are braked by the brakes 8 and 9. Installation the overrunning clutch on the shaft of the lower feed roll reduces the accuracy of the feed pitch caused by the inaccuracy of its manufacture by as many times as the diameter of its leading part is larger than the diameter of the feed roll. Execution of the gear mechanism in the form of a gear sector and gear reduces Also, the accuracy of the feed step, since the kinematic error in the sector arc with the same feed step is constant, and it is easy to take into account when setting up. The effect of using the proposed device will be 1000 rubles per year. material in the working area of the press, containing upper and lower feed rollers mounted in the housing on the shafts, interconnected by a gear train, an overrunning clutch, including the driven part and the leading part, carrying A gear wheel, a toothed sector set in a swinging motion, characterized in that, in order to increase the accuracy of the feeding step, the overrunning clutch is mounted on the shaft of one of the feed rolls, its driven part is rigidly connected to this shaft, and the toothed sector is fixed in the housing with ability to interact with the gear.
