Abstract

Изобретение относитс к обработке металлов давлением, а именно к прессованию металлов и может быть использовано в цехах металлургических заводов. Цель изобретени - повышение уровн техники безопасности. Заготовку 1 устанавливают на матрицу. На верхнем торце заготовки размещают ложную шайбу 2, за которой устанавливают дополнительную металлическую буферную шайбу 3. К концу прессовани буферна шайба 3, заполн матричную воронку и формоизмен сь, поглощает кинетическую энергию подвижных частей пресса, тем самым исключа их удар о неподвижные части. Высоту каждой шайбы рассчитывают по математическим формулам , приведенными в описании. 3 ил.The invention relates to the processing of metals by pressure, in particular to the pressing of metals and can be used in the shops of metallurgical plants. The purpose of the invention is to improve the level of safety. The workpiece 1 is set on the matrix. A false washer 2 is placed on the upper end of the blank, behind which an additional metal buffer washer 3 is installed. By the end of pressing the buffer washer 3, filling the matrix funnel and changing, absorbs the kinetic energy of the moving parts of the press, thereby eliminating their impact on the stationary parts. The height of each washer is calculated according to the mathematical formulas given in the description. 3 il.

Claims

Claim

A method of pressing blanks without a press residue, in which the blank is mounted on a matrix containing a matrix funnel and a working belt, a false washer made of easily removable elastic material, such as graphite, is placed on the upper end of the blank, after which the blank is extruded with a press washer through the matrix, characterized in that, in order to increase the level of safety for false washer mounted additional buffer metal washer, the height of the first of them is determined from the ratio of ^H 3 = 4'h, and SEASON at the second ratio determined from

1648 583 8

Hi = 0.6 · Ng (1 + -J-) + K, where Hi is the height of the buffer washer: Ng is the height of the matrix funnel: H3 is the height of the false washer; : L - hood;

K is the distance between the press washer and the die to the end of the pressing process:

S - coefficient of compaction of the material of the false ”washer:

5 h - the height of the working belt of the matrix.
