Description
предлагаемый способ повышает изко:,оугтойчивос,ти рамных и дисковых пил посредством закалки вершинок зубьев без их последующего отпуска, осуществл емой при помощи элохтрохонтактного кагрева . Способы элехтроконтакткого нагрева излелий дл различных видов термической обработки, в частности , закалки, отпуоха, а также кагрева под ковку и примен ема дл этого вестпы. В насто щее врем термическа обработка рам.ных и дисковых пил производитс на твердость 40- 45 К с дл обеспечени возможности их последующей обработки: вальцовки, правки и разводки зубьев. Особенпостыо предложенного способа повышени износоустойчивости рамных и дисковых пил вл етс дополнительна (вторична ) за салка вершинок зубьев пил На повышенную твердость без последуюпцего отпуска их, осуществл ема посредством эле1ктр0контактноГо нагрева. Предложенный способ термической обработки обеспечивает повышение износоустойчивости ре;-кунлнх лезвий рамных и дисковых пил в 1,5-1,6 раза, за счет высо:;ой твердости вершинок зубьез в пределах 60-61- , а также всзмо:::ность последующей механической обработки: вальцовки, правки и разведки зубьев. Иа чертсж:е изоб)а кеиг1 злектри-еска cjveya установки длл закалки вершинок зубьев рам;п-1х и дисковых пил.

Вершинка зуба при ирохождеиин тока разогреваетс до закалочной темнературы. При прекращении подачи тока производитс охлаждение верщинки зуба пилы за счет теплоотдачи в тело полотна пилы. Дл закалки используютс аппараты дл пайки ленточных пил или дл точечной электросварки.The proposed method increases izko: ogstabios, tame and circular saws by quenching the tops of the teeth without their subsequent tempering, carried out with the help of electro-contact cagreve. Electro-contact heating methods for various types of heat treatment, in particular, hardening, heat treatment, as well as heat treatment for forging, and used for this process. At present, thermal processing of frame and circular saws is carried out on a hardness of 40-45 K s to enable their further processing: rolling, straightening and setting of teeth. The particular feature of the proposed method of increasing the wear resistance of frame and circular saws is an additional (secondary) method for cutting the tops of the saw teeth. On increased hardness without subsequent release by means of electrically contact heating. The proposed method of heat treatment provides an increase in wear resistance of re; -kunlh blades of frame and circular saws by 1.5-1.6 times, due to the high:; th hardness of the tops of teeth in the range of 60-61; and also the following mechanical processing: rolling, editing and reconnaissance teeth. Ia Chertszh: e izob) and keig1 electr-esk cjveya installation dll hardening tops of the teeth of the frames; n-1x and circular saws. Its 51l; I: cable 1 ki: pz1 2 but the side surfaces are clamped by two industrial circuits: ct Gi: 3, to which the electric current of the corresponding parameters is supplied, providing: a single-phase step-down transformer 4 connected to the network 127-2.20 at. The tip of the tooth at irohodeiin current heats up to quenching temperature. When current is stopped, the tip of the saw tooth is cooled by heat transfer to the body of the saw blade. For quenching, soldering machines or for electric spot welding are used.
