SU339433A1 - STANINA HYDRAULIC PRESS - Google Patents

Description

The proposed invention otisoit to the field of Forging and pressing alloys. Machine-building: and.

The beds of hydraulic presses are known, which are represented by 1, - not a Herodvarg. Body. On the other hand, new frames consisting of crossbars and etocans, interconnected, inside which the working cylinders are located, under. parts,

Beds get a pre-BARRIERNESS as a result of tightening stiff holons, which can be several, as a result of their winding assembled along the front with high-strength IL11 wire tape with NLP CONTAINS

alternating voltage, or by dressing the pre-wound ba: mediaej-katun1ek with the following m. their tension, which can be achieved in the working force cylinders, which are installed in the cylinders, and installed in clearances with strut-and-spacers ai with barbels of the so-called distanned plnt. In the latter case, katunzhi bandages, which may be several, are also located along the CTaiHHHbi front. The disadvantages of the prestressed starks mentioned above and, vm.tot: given by high strength wire or tape. inside

beds, as the working cylinders and tech. 1logical-and.instru.ment rests directly in -sami river. This is due to the fact that parts of the stanina — the transom-and-pillars and the struts — are kept from a mutual right-turn in the main trehle: M between II and the winding.

Winding of a stage with an unbroken wire or tape along them (the front requires repeated welding of the ends of the weed or tape, since the weight of the buits is c) from the high-quality wire 1 l: g of the tape is small (about 70 kg). As is known, a decrease in the strength characteristics of the nrono yuki or tape itself is observed at the welding site, which increases the strength characteristics of the entire winding and does not make it possible for the network to fully utilize all the infrastructure; 5a high-strength tape and wire.

In order to facilitate modulation, transport and iroik removal and elimination of the harmful effects of eccentric loads, the winding is made in separate elements having a length shorter than the perimeter of the frame, and assembled into bundles attached to the components of the base.

StaN: Ina can have a semi-linguistic crossbar and only one crossbar, or both, which can also be wrapped with high-strength: Noah} 1th silt wire, etc.)) than the winding; s already lead along the front of the mangnea or individually for each rsch.ch, using irnlvvy (bracket) 1s) on the spacers, silt: and omatisa the whole frame as a whole, using all. from the spring methods of ebork-and such xHEEL.

FIG. 1 and 2 show the hydraulic lresse frame, aa of fig. 3, a, b-some variants of the “replenishment of the ribbon.

Stalin (dig. 1) of the hydraulic section consists of crossbars} and 2 and prefixes 5, made by a high-strength tape, rods, MI, ropes or wire 4, are distributed in a certain way in the slots of the frame, and between the cross member and the Remote plates 5 can be installed.

The bed can also be made with or with one, IL.I with two semi-cylindrical bolts (Fig. 2), also wrapped with a high-wound tape or wire.

Such solutions of the tensioned bed, nlprnmer, hydraulic hammer press, provide the following possibilities.

Hydraulic screw press hammer is designed to obtain precise parts with dynamic application of the working force. Therefore, it is necessary to ensure precise direction of the crawl, to exclude opening of the joints when working between the crossbars and the uprights, to reliably counteract eccentric forces that run during the working stroke.

The structure of the frame (Fig. 1) provides for HBaeT for a.Mvnnu sting columns of high-strength tape, wire, rods or ropes, directly connecting cross-pieces 1 and 2 in the area of fitting racks, spacers, with the ends of the Measures: pieces of tape, wire or € the tail, individually or in groups, is attached to the crossbars. In this case, the middle part of the crossbars / and 2 is completely free from the winding, which makes it possible to easily solve questions with the supply and fastening of pipelines and fix the press itself, the hammer on the foundation, taking into account the dynamic loads Vasiliy working with such a m.

The proposed bed frame makes it possible to use all the strength capabilities of wire and tape, COMPLETELY EXCLUDING; welding the CONDITIONS of the mat and tape, as the length of their lengths is much less than the length of wires and lines in riots.

The endowment of K1 is fixed, and the ends can be achieved using radial embedding of the ends with a clamp on their bar, the ends themselves being mounted, for example, on glue or babbit etc., (fig. 3, a) or by means of a conical embedding ( Fig. 3.6), and between

the ends, for example, tapes, are wedged, and all the ends are also poured with glue, broken or sealed, or, for example, during conical insertion, the loose ends are simply poured with babbit.

The prestressing voltage of the proposed station 1 {and it is possible to have any known means. For example, the no-cjie assembly can be stretched with a force exceeding the nominal and installed measuring distance plates 5 (Fig. 1), or using, for example, jacks to stretch bundles (lashes) of tape, eg. ezoloki, rods or ropes with the subsequent setting of measuring distance plates 5 directly under the heads in which their ends are sealed, or with the help of narpeiBa bundles (lash) of tape, wire, (Rods or their subsequent input into the mill-1nu, etc.

In the frame, in crossbars and spacers, for

Convenience and quick assembly-disassembly can be performed, for example, grooves open to the outside, into which it is easy to insert and remove said bundles (sticks) from tape, wire, ropes and rods.

Subject invention

A hydraulic press bed consisting of high cross-section windings and struts, characterized in that, in order to facilitate installation and transportation, to eliminate the harmful effects of eccentric loads, the winding is made in the form of individual elements.

The 1-meter bedpan gauge tucked in km, fixed on the components of the frame.
