PERIODICAL: Mashinostroitel',, no. 2P 1961,-17
TEXT: The author reports-on new,parts made or plastics fabricated at,
the Lyuberetskiy.zavod plastmass (Lyubertsy Plastics Plant) which wereformerly
madeof non-ferrous or ferrous metal., Thus, e.g.. the casing-and cover ofa
filter,. formerly made of,zinc alloy with allowances.for mechanical w9rking is
.know made of fiber aterial ("voloknit~'),: which made it possible to reduce its
weight 3 times. The parts are.pressed in a single-deck press mold with lower,
ejector and electric heating on a 180-ton hydraulic press.: The temperature of
die and punch is 150 - 1600C., Th6:shaping parts of the press mold are lubricated
with:oleic acid.. Pressing takes 3 minutes.--"The cover of the lathe-chuck was
Tormerly made from gray castiron with allowances formechanical working. . Now
thatthese covers are made of plastics, 17O.tons of cast iron are saved annually.
'Moreover, the weight of the,covers was reduced 5 times since they are being made
of plastics, the initial material for.which is wood powder. The parts are pressed

TEXT: The distribution of the meta 1 pressure upon the ro lls of-mill stan ds
for various types of groovings.is investigated. As the pipe enters the following
stands the pressure in the preceding ones''is reduced. At steady sta .te the pres-.
sures on the rolls in all the stands of the mill attain their minimum values but
they are not equal to each other. The maximum pressure upon.the rolls registered
in.the course of measurements was 72.,tons while rolling Pipes 59 x 37.5 of steel,
15XM (15Khm) (=I-rd stand) . It was' established that the pressure on the rolls
,increases with the decrease in pipe thickness and with the increase of the con-.
tent of the Alloy elements in the steel. Aformula is-derived for determining_
the specific pressure.w,hile rolling pipe on long mandrels and the pressure, on the

ABSTRACT: So far the,maximum thickness.ofaluminum, alloys-cutindustriallyby the
gas-electric-arc m'et'hod'-has b'ee-n,70 mm. Further technical progress. dictates the need
-to enlarge this-maximum.'In this connection, the authors investigated.the possibility
of cutting Al alloys up to'250 mm thick by the gas-electric prc method and developing
:efficient equipment and techniques for this purpose. AN IP-150/150K rectifier deve-
loped-by the authors wos'used an the power source for the cutting are and the cutting
was performed with the aid of an PM-1 semiautomitic rectilinear cutting machine.

Slabs of the.Al alloys AMg6 and.D6 and avial-type alloys 70-250 mm thick were cut. A
major factor in cutting metal plate.is the so-called "piercing time"s(time from
the instant of ignition of the cutting ircuntil complete melting of the spot at
which'the arc is first applied): the shorter the piercing,time is,,~the faster the
cutting rate; this involves a certain'(optimal) rate of,hydrogen consumption for a
specified thickness of metal. It was found that the optimal consumption of H in-
2
creases with increasing thickness of the.metal being cut owing to the attendant in7_
crease in the length of the cutting arc and hence also in the amount ofthe hydrogen
dissociated. Another factor to be considered is the optimal angle'of approach of.th
a
~electric arc to the line of planned cut and the subsequent.rate of advance of the
cutting head. Oscillographic studies of the cha .nge i.n.,cutting-arc ~:voltage following:,
contact with metal showed that then a linear increase in voltage takes place. This
made it possible to develope a' special servo system functionally through feed-
back -- relating the cutting rate.to.the arc voltage as based on .,the'use of a'cutting
head powered by a DC,motor whosea-cmature is connected to a power system via an MU
magnetic amplifier with self-magnetization and internal positive:current feedbackv
whicli adjusts the motor RPM to,an extent.corresponding to the required.rate of advance
of the cutting~head as function of Lheoperation performed,at the moment'(no load,
ignition, approach to planned line of cut,,actual .cutting). On th-1Ia,, basis the OPR-1 Lb
plate-metal cutting apparatus for rectilinear as well as profile cutting has been do-..
veloped; it is equipped with a special extensible-panel forrmota control of:the.
operations if desired.:Orig.-art.lhas: 5 figures,.1
