Изобретение относитс к области газовой резки металлов, касаетс усовершен ствовани специализированных машин дн надрезки круглого проката и наиболее эффективно может быть использовано при газоной надрезке заготовок перед ломкой их на прессе в поточных лини х подготовки заготовок трубопрокатных агрегатов,The invention relates to the field of gas cutting of metals, relates to the improvement of specialized machines for cutting round rolled metal and can be most effectively used for lawn cutting of blanks before breaking them on a press in the flow lines for preparing tube blanks,

Известно устройство дл газовой резки, содержащее основание, на котором закреплен зубчатый сектор и смонтирована при- воана каретка с суппортом резака, на вьь ходком валу привода которого установлена шестерн , взаимодействующа с зубчатым сектором 1 ,A device for gas cutting is known, comprising a base on which a toothed sector is fixed and a carriage is mounted with a support for a cutter, on which a gear wheel, which cooperates with a toothed sector 1, is mounted on a drive shaft,

Это устройство требует много времени на настройку при изменении диаметра раэрезаемого проката.This device requires a lot of time to adjust when changing the diameter of the section to be rolled.

. Целью изобретени вл етс повышение производительности труда путем уменьшени вспомогательного времени на настройку, приизменении диаметра разрезаемого проката.. The aim of the invention is to increase labor productivity by reducing the auxiliary set-up time, while changing the diameter of the rolled stock.

Указанна цель достигаетс благодар тому, что на каретке предлагаемого устройства дл газовой резки вьшолнены дугооб2This goal is achieved due to the fact that on the carriage of the proposed device for gas cutting are completed arc

разные пазы, суппорт.с резаком размещен в этих пазах, на суппорте смонтирон н зубчатый венец, а на валу привода устаногз- лена дополнительна шестерн , взаимодействующа с зубчатым венцом.Different grooves, a support with a cutter are placed in these grooves, on the support of the spigot and on the ring gear, and on the drive shaft there is an additional gear that interacts with the ring gear.

На фиг. 1 изображено машина дл нпрегь ки проката с предлагаемым устройством дл газовой резки, общий вид; на фиг. 2 показано устройство дл газовой резки в увеличенном масштабе; на фиг. 3 дан разрез по А-А на фиг. 2.FIG. 1 shows a rolling machine with the proposed gas cutting device, general view; in fig. 2 shows a gas cutting device on an enlarged scale; in fig. 3 is given a section along A-A in FIG. 2

Устройство 1 дл газовой резки устанавливают на кронштейне 2 с возможностью перемещени от привода 3, Кронштейн 2 установлен на тележке 4, котора может перемещатьс по направл ющим 5 от привода 6.The gas cutting unit 1 is mounted on the arm 2 for movement from the drive 3, the bracket 2 is mounted on the carriage 4, which can move along the guides 5 from the drive 6.

Claims

. The device for gas cutting (Fig. 2, 3 consists of a supporting base 7, on which the gear sector is fixed: 8 and the driving carriage 9 is mounted, not having a support 10 with a cutter 11. The carriage 9 bv eana with a drive 12 pbsmean gear 13. The caliper 10 is placed in the groove 14 of the carriage 9 and provided with a gear crown 15, which interacts with ujectopfleft 16 located on the shaft 17 of the drive 12. The device operates as follows. The cart 4 is mixed along the guides 5 from the drive 6 and stops in position 3 and brings the cutting device 1 to the workpiece 18. The cutter 11 is installed at a certain distance n: n {from the workpiece, the cutting process starts, the drive is turned on 12, the gear 13 is driven around the gear sector 8, the carriage 9 moves in grooves 19 (Fig. 2), moving up the caliper 10 with the cutter 11, because the caliper with the ring gear 15 is in engagement with the gear 16 mounted on the common with the gear 13 of the drive shaft 17, it receives an additional offset and moves along the groove 14. The angle between the normal to the surface in otovki 18 and the longitudinal axis of the torch 11 in diak1otrapy (second plane continuous clearly varies reaa process, the molten metal is continuously and efficiently removed from the incision. In the case of a cutting process, the axis of the cutter occupies a vertical or close to vertical position. The carriage 9 stops. The drive 3 is turned on and retracts the device 1 from the press 18. Then, at the next cut, the cycle repeats. The proposed gas cutting device, in comparison with the known samples of similar equipment, allows to reduce reconfiguration when switching from cutting solid round billets of one diameter to another, to mechanize the process of cutting cuts before breaking into the press and thereby eliminate manual labor when cutting the original bar into technological billets and increase productivity The invention of the device for gas cutting, predominantly round steel, containing a base on which the toothed sector is fixed and the drive carriage is mounted with a torch caliper, on the output shaft of which a gear is installed, which interacts with the said gear sector, and that, in order to increase labor productivity by reducing the auxiliary time for setting when changing the diameter. The carriage is cut, arcuate grooves are made on the carriage, a caliper with a cutter is placed in these grooves, a gear ring is mounted on the caliper, and an additional gear is installed on the rvuiy drive and a gear ring.
