Description
Известны различные способы электрозакалки длинных изделий с применением токов высокой частоты и с использованием устройств, устран ющих деформацию изделий во их закг1лки.Various methods of electrical hardening of long products are known using high frequency currents and using devices that eliminate the deformation of the products in their locks.
Однако примен емые способы и устройства не обеспечивают по.п чение равномерной твердости и пр молинейности подвергающихс закалке длинных изделий.However, the applied methods and devices do not ensure uniform hardness and straightness of quenched long products.
Особенность насто щего изобретени заключаетс в том, что, с целью обеспечени равномерной твердости по длине щтанги и пр мо.шнейности их после закалки, штангу жестко фиксируют в горизонтальном пололсении между роликами, с помощью которых штанга вращаетс и перемещаетс поступательно.The peculiarity of the present invention is that, in order to ensure uniform hardness along the length of the string and straightness of them after quenching, the bar is rigidly fixed in a horizontal polossenii between the rollers with which the bar rotates and moves progressively.
Дл осуществлени этого способа примен ют станок, в котором имеетс четыре группы косораспо.юженных пи.-щндрических или глобоидных роликов.To implement this method, a machine is used, in which there are four groups of skewed pi. -Shchndricheskie or globoid rollers.
На чертеже показана обща схема станка дл электрозакалки длинных щтанг-оправок.The drawing shows a general scheme of a machine for electrical hardening of long shtang-mandrels.
Станок состоит из четырех групп роликов по три ролика в каждой. Нижние опорные ролики / холостые и размещены на одной пр мой. Оси роликов развернуты под некоторым углом к оси закаливаемой щтанги 2. Верхние ролики 3 - приводные и развернуты под тем же углом к оси щтанги. Вращение роликам передаетс от общего вала через щестерни 4. При помощи винтов 5 приводные ролики прижимаютс к щтанге. В среднем промежутке между группами роликов установлен индуктор 6 и спреер 7.The machine consists of four groups of rollers with three rollers each. Lower support rollers / idle and placed on the same line. The axes of the rollers are turned at a certain angle to the axis of the hardened bar 2. The upper rollers 3 are driven and turned at the same angle to the axis of the bar. The rotation of the rollers is transmitted from the common shaft through the pinwheel 4. With the help of screws 5, the drive rollers are pressed against the shaft. In the middle interval between the groups of rollers, an inductor 6 and a sprayer 7 are installed.
Электрозакалку длинных щтанг осуществл ют с применением индукционного нагрева. Во врем процесса закалки штанга жестко зажата между всеми роликами и получает вращательное движение от привода роликов. Поступательное движение щтанги вызываетс разворотом осей вращающихс роликов. Величина поступательного движени The electric hardening of long shtangs is carried out using induction heating. During the quenching process, the rod is rigidly clamped between all the rollers and receives a rotational movement from the drive rollers. The forward movement of the rod is caused by the rotation of the axes of the rotating rollers. Translational magnitude
