Description

Предлагемый способ испытани  карандашных стержней на дробление позвол ет вы вить их дефектность до окончательной запрессовки , т. е. до выпуска готовой продукции и тем самым снизить брак последней.The proposed test method for crushing pencil rods allows revealing their defectiveness prior to final pressing, i.e., prior to the release of the finished product and thereby reducing the marriage of the latter.

Сущность способа за1стючаетс  в том, что карандашные стержни без кле  закладываютс  в дерев нные или металлические дощечки с желобками. Дощечки с комплектом стержней прессуютс  винтовым, например, прессом. После выдерживани  под соответствующим давление .м в течение некоторого промежутка времени дощечки распрессовываютс  и производитс  отбраковка дефектных раздробленных стержней. Пресс должен иметь указатель величины усили  прессовани .The essence of the method is made in the fact that non-adhesive pencil sticks are laid in wooden or metal planks with grooves. Plates with a set of rods are pressed with a screw, for example, a press. After being held under the appropriate pressure for a certain period of time, the plates are pressed out and the defective broken rods are rejected. The press must have an indication of the magnitude of the pressing force.

Давление прессовки устанавливаетс  в зависимости от требований прочности, предъ вл емой к испытуемым стержн м.The pressing pressure is set depending on the strength requirements imposed on the test rods.

Предмет изобретени Subject invention

Способ испытани  карандашных стержней на дробление, отличающийс  тем, что карандашные стержни до окончательной запрессовки предварительно кратковременно прессуют без кле  в дерев нные или металлические дощечки с желобками при помощи винтового , например, пресса с указателем величины усили  прессовани  и после распрессовки производ т отбраковку и определ ют количество дефектных раздробленных на куски стержней.The method of testing pencil rods for crushing, characterized in that before the final pressing, the pencil rods are preliminarily pressed without glue into wooden or metal planks with grooves using a screw, for example, a press with an indicator of the amount of pressing force, and after unpacking are rejected the number of defective rods broken into pieces.
