Description

В насто щее врем  изготовление сверл производитс  механической и термической обработкой круглого стального нрофил , получаемого с прокатного стана, причем операции прокатки профил  и завивки его производ тс  на различно.м оборудовании, не св занном друг с другом технологически.At present, the manufacture of drills is carried out by mechanical and heat treatment of round steel nofil obtained from a rolling mill, and its profile rolling and curling operations are performed on various equipment that is not technologically related to each other.

Предлагаемый способ производства сверл на комбинированном прокатно-завивочном стане позвол ет совместить на одном агрегате две последних операции (прокатку и завивку), что снижает стоимость производства и повышает качество сверл.The proposed method for producing drills on a combined rolling and rolling mill allows one to combine the last two operations (rolling and rolling) on one unit, which reduces production costs and improves the quality of drills.

За валками прокатно-завивочного стана устанавливаетс  матрица с направл ющими выступами, имеюпда  профиль, соответствующий профилю завивки сверла, причем закручивание профил  по выходе его из валков происходит принудительно под действием сил, сообщаемых валками переднему концу прутка при прокаткеВместо матрицы, дл  образовани  профил  завивки сверла, возможна установка двух роликов, расположенных под соответствующим углом друг к другу.Behind the rollers of the rolling-curling mill, a matrix with guide lugs is installed, having a profile corresponding to the profile of the drill, whereby the profile is twisted out of the rollers by force of the rollers to the front end of the bar during rolling. Instead of forming the profile, It is possible to install two rollers located at an appropriate angle to each other.

Claims (2)

1.Способ производства витых сверл, отличающийс  совмеще нием двух операций: «прокатки профил  и «завивки профил  на одном прокатно-завпвочном станке, на котором завивка профил  происходит принудительно под действием усилий, возникающих при прокатке с торможением переднего конца при закручивании профил  в матрице.1. A method of producing twisted drills, which combines two operations: “rolling a profile and” rolling a profile on one rolling-seamer, on which a profile curling occurs by force under the action of the forces that occur when rolling with the braking of the front end when the profile is twisted in the matrix. 2.Форма выполнени  устройства дл  осуществлени  способа по п. 1, состо ща  из станка, имеющего прокатные валки и профилированную матрицу, отличающа с  тем, что с целью принудительной за№837172. The form of execution of the device for carrying out the method according to claim 1, consisting of a machine having rolling rolls and a shaped matrix, characterized in that with the aim of compulsory assignment No. 83717 вивки прокатанного профил  в матрице, последн   установлена непосредственно за валками.rolled strip profile in the matrix, the latter is installed directly behind the rollers. 3- Форма выполнени  устройства по п. 2, отличающа с  тем, что вместо матрицы дл  образовани  профил  завивки сверла установлены два ролика под соответствующим углом друг к другу.3- The form of the device according to claim 2, wherein instead of a matrix, two rollers are installed at a suitable angle to each other instead of a matrix to form a drill bit profile.
