Description
Изоб|ретение относитс ж .металлообработке л .может быть использовано лри оверлекии от1верст.ий Б труднооб-рааатьиваемы.х в зких материалах.The invention relates to metal processing, and it can be used for overlaying bores of difficult-to-work viscous viscous materials.
Из:ве СТ1НЫ .апиральные сверла, рабоча часть «отарых выполнена стутенчатой.From: ve ST1NY. Spiral drills, the working part of the open bar is made by step.
Лрвдлагаемое свйрло отличаетс тем, что кажда его стуиепь выполнена ino винтовой паверх.ности с количеством заходов, ра.в,ны.м или (К1р1атньгм (количеству (перьев сверла. На наибольшим диаметре .ка гйдой ступени выполнены фаски.An extension is characterized by the fact that each of its steps is made ino screw-top with the number of visits, rav, now, or (K1p1atngm (number (drill feathers. At the largest diameter of the next step, chamfers are made).
Это иовышает чистоту обрабатываемой поверхности .This increases the cleanliness of the surface to be treated.
На ф|и,г. 1 ,изаб|р.ажено предлагаемое сверло , общий вид; на фиг. 2 - сечен.ие по А-А на фиг. 1.On f | i, g. 1, izab | r.azheno proposed drill, a general view; in fig. 2 is a section along A-A in FIG. one.
Рабоча- часть 1 имеет ступени 2, кажда из 1кото,рых Быподне,на ino виитовой поверхности 3 с miarOiM ап,и,р,али Т. На наибольшем диаметре каждой ступени выполнены фаюки 4. Число за-.ходов виитавой |П01верХност,и должно быть равным или .кратным количеству перьев сверла.Worker part 1 has steps 2, each of 1 koto, ryb bypodne, on the ino viite surface 3 with miarOiM an, and, p, ali T. On the largest diameter of each step, there are four fayuks 4. The number of passages of the vi tita | must be equal to or multiple of the drill feathers.
iFIo мере износа и переточки режущей части перВой стуненч ее диаметр Д уменьшаетс и в работу вступает кромка 5 второй ступени с диаметром Дг, котора , благодар наличию положительного значени заднего угла а., срезает припуск, обеспечива нор.мальную работу сверла независимо от значени паибольшего диаметра первой ступени сверла, получаемого в пропессе обработки .iFIo measures wear and re-cutting of the cutting part of the first stunench, its diameter D decreases, and the edge 5 of the second stage enters the work, with a diameter Dg, which, due to the positive value of the back angle a., cuts off the allowance, ensuring normal operation of the drill the first step of the drill obtained in the process processing.
