Description

Недостаток известного ударного инструмента заключаетс  в том, что он не может быть использован многократно.A disadvantage of the known percussion instrument is that it cannot be used many times.

В описываемом способе острие ударного инструмента предлагаетс  подвергать многократной кузнечной отт жке после каждого затуплени .In the described method, the tip of a percussion instrument is proposed to be subjected to multiple forging delay after each blunting.

На чертеже показаны последовательные стадии изготовлени  остри  ударного инструмента.The drawing shows the successive stages of manufacturing the tips of a percussion instrument.

Дл  этого на торец цилиндрического стержн -заготовки / ванным способом наплавл етс  износоустойчивый металл 2 (см. чертеж). В торце заготовки образуют отверстие 3, которое заплавл етс  металлом и обеспечивает прочное соединение заготовки с наплавл емой частью - наконечником. Затем кузнечным способом наплавленному металлу придают форму режущего остри  4.To do this, wear-resistant metal 2 is welded onto the end face of a cylindrical rod / by a bathing method (see drawing). At the end of the preform, a hole 3 is formed, which is sealed with metal and provides a strong connection between the preform and the weld part — the tip. Then, by the forging method, the weld metal is shaped into a cutting edge 4.

Наплавл емый износоустойчивый металл предлагаетс  в следующем химическом составе С 0,5-1,9%; Gr 2,3-10%; Мп до 0,6%; Si до0,65%; Мо О-1%; Ti О-1%; S до 0,04%, Р до 0,04%. Такой металл хорощо куетс , а путем соответствующей термообработки (закалки с отпуском) ему можно придать высокие механические свойства. После затуплени  остри  его кузнечным способом восстанавливают.The weldable wear-resistant metal is proposed in the following chemical composition C 0.5-1.9%; Gr 2.3-10%; MP up to 0.6%; Si up to 0.65%; Mo O-1%; Ti O-1%; S to 0.04%, P to 0.04%. Such a metal is good forged, and by appropriate heat treatment (quenching with tempering) it can be given high mechanical properties. After blunting, the tips are forged by its forging method.

Предмет изобретени Subject invention

Способ изготовлени  остри  ударного инструмента путем наплавлени  металлического наконечника с последующей заточкой, отличающийс  тем, что, с целью повторного использовани , его подвергают многократной кз знечной отт жке.A method of manufacturing the tips of a percussion instrument by fusing a metal tip followed by sharpening, characterized in that, for the purpose of reuse, it is subjected to repeated crushing.
