Description

Способы вырубки зубцов на заготовках пил посредством инструментов (пуансонов н матриц) изготовленных точением в форме цжпгндрических круглых тел с витками, в виде винтовых нарезок, известны. Однако известные способы не обеспечивают требуемых качества и производительности вырубки.Methods for cutting teeth on saw-pieces by means of tools (punches and dies) made by turning in the form of tszpgndrichesknyh round bodies with turns, in the form of screw cuts, are known. However, the known methods do not provide the required quality and productivity of cutting.

Предлагаемый способ изготовлени  зубцов ножовочных полотен, путем штамповки (вырубки) их в два приема, позвол ет получить остроконечные зубцы лучшего качества и значительно повысить производительность труда.The proposed method of making teeth of hacksaw blades, by stamping (cutting them out) in two steps, makes it possible to get pointed teeth of better quality and significantly increase labor productivity.

Предлагаемый способ заключаетс  в том, что В1з1рубку зубцов производ т в две операции инструментом с шагом вдвое большим чем шаг зубцов у издели . Причем после первой вырубки производ т вторую , перемеща  заготовку на величину одного шага издели .The proposed method consists in the fact that the Bubble teeth are made in two operations with a tool with a step twice as large as the tooth pitch of the product. Moreover, after the first cutting, the second cutting is done, moving the workpiece by the amount of one step of the product.

На фиг. 1 )13ображена схема использовани  предлагаемо о способа при образовании зубьев издели  (перва  операци ); на фиг. 2-| то же (втора  операци ).|FIG. 1) 13 shows the scheme of use of the proposed method in the formation of the teeth of the product (first operation); in fig. 2- | the same (second operation). |

При первой операции на ленте-заготовке / вырубаютс  зубь  за-In the first tape operation, the teeth are cut

кругленной или трапецеидальной формы с шагом, равным двум шагам зубьев готового ножовочного полотна и несколько большей высоты.round or trapezoidal shape with a step equal to two steps of the teeth of the finished hacksaw blade and somewhat greater height.

При второй операции лента смещаетс  относительно зубьев инструмента 2 на рассто ние, равное одному шагу зубьев готового ножовочного полотна и производитс  вырубка гребешков зуба. В результате пересечени  .плоскостей вырубки первой и второй операции вершина зуба ножовочного полотна получаетс  достаточно острой.In the second operation, the tape is displaced relative to the teeth of the tool 2 by a distance equal to one step of the teeth of the finished hacksaw blade and the combing of the tooth is cut. By intersecting the cutting planes of the first and second operations, the top of the tooth of the hacksaw blade is quite sharp.

В цел х избежани  зат гивани  зубьев ножовочного полотна в одну сторону, направление-удара пуансона в первой и второй операци х- противоположно.In order to avoid sharpening the teeth of the hacksaw blade in one direction, the direction of the stroke of the punch in the first and second steps is opposite.

Это осуществл етс  либо изменением положени  пуансона и матрицы (матрица сверху, пуансон снизу), либо подачей па вторую операцию заготовки перевернутой на 180°.This is done either by changing the position of the punch and die (top matrix, bottom punch) or by feeding the second billet operation upside down by 180 °.

Предмет изобретени Subject invention

Способ вырубки зубцов у пил и ножовочных полотен, отличающийс  тем, что, с целью получени  остроконеч1 ых зубцов правильной формы, вырубку производ т в две операции инструментом (пуансоном и матрице ), выполненным с шагом зубцов вдвое большим , чем шаг зубцов у издели , а после первой вырубки тем же инструментом производ т вторую вырубку при смещении (подаче) заготовки на щаг издели .The method of cutting teeth at saws and hacksaw blades, characterized in that, in order to obtain sharp-pointed teeth of a regular shape, cutting is performed in two operations with a tool (punch and die) made with a tooth pitch twice as large as the tooth pitch of the product, and after the first punching with the same tool, the second punching is carried out when the workpiece is shifted (fed) to the product bar.
