Abstract

Invention refers to mechanisms used in the presses in order to obtain required pressing force. Its purpose is to expand functional capacity of the press providing possibility of mechanism operating at different inclination. It has been provided connecting press punch and frame via rhomboid mechanism which the longest sides joint and the shortest sides joint is connected via hydraulic cylinder. The particular use in the performance of rhomboid mechanism is positioning mechanism then its shortest links are on one line. It is possible to obtain a theoretically unlimited punch pressing force in this position. The proposed mechanism in hydraulic press is recommended for use in mobile equipment, where it can happen operating at different inclination. Pressing can be done in a closed and the continuous flow dies.

Description

Izgudrojuma aprakstsDescription of the Invention

Izgudrojums attiecas uz mehānismiem, ko izmanto presēs nepieciešamā presēšanas spēka iegūšanai.The invention relates to a mechanism used to obtain the pressing force required in a press.

Ir zināms preses stieņmehānisms (patents RU 2378118 Cl), kurā preses puansons ir pievienots statnei ar sešu locekļu, deviņu šamīru un slīdpāra starpniecību, pie kam minētie locekļi savstarpēji veido simetrisku un noslēgtu piecstūra kontūru. Šī mehānisma trūkums ir lielais locekļu skaits spēka pārnešanas ķēdē, kas izraisa pastiprinātu dilšanu, un lieli gabarīti, kas traucē tā izmantošanu mobilā tehnikā.A press rod mechanism is known (patent RU 2378118 Cl), in which a press punch is attached to a stand through a six-membered, nine-sheared, and a sliding pair, said members forming a symmetrical and closed pentagonal contour with each other. The disadvantage of this mechanism is the large number of members in the power transmission chain, which causes increased wear, and the large dimensions that hinder its use in mobile technology.

Zināmajā hidrauliskās preses mehānismā (patentpieteikums CH 681872 A5) puansons ir pievienots statnei trijos punktos, izmantojot hidrocilindru un trīs stieņu pārus. Šim mehānismam ir nepieciešami vismaz pieci parastie un trīs dubultie šamīri. Mehānisma kustīgo savienojumu skaits ir liels un tā darbināšana nav paredzēta slīpumos.In a known hydraulic press mechanism (patent application CH 681872 A5), a punch is attached to a stand at three points by means of a hydraulic cylinder and three pairs of rods. This mechanism requires at least five conventional and three double shamers. The mechanism has a large number of movable joints and is not intended for operation on inclines.

Tehniskais uzdevums, ko risina piedāvātais izgudrojums, ir, samazinot locekļu un kustīgo savienojumu skaitu mehānismā, nodrošināt puansona darbības iespēju slīpumos. Šis mērķis funkcionālo iespēju palielināšana - piedāvātajā izgudrojumā ir sasniegts, savienojot statni un presēšanas puansonu ar romboīda mehānismu, kura garāko malu šamīrs un īsāko malu šamīrs ir savienots ar hidrocilindru. Konkrētos izpildījuma variantos ir izmantota tāda romboīda mehānisma īpašība, ka, presēšanas ciklā novietojot romboīda mehānisma īsākos locekļus uz vienas līnijas, ir iespējams iegūt teorētiski neierobežotu presēšanas spēku puansonam. Reāli presēšanas spēka maksimālo vērtību šajā pozīcijā ierobežo romboīda mehānisma locekļu un puansona izturība.The technical problem solved by the present invention is to provide the possibility of a poison operation on slopes by reducing the number of limbs and moving joints in the mechanism. This object is to increase the functional capabilities - the present invention has been achieved by combining a strut and a press punch with a rhomboid mechanism having a long-edge shammer and a short-edge shammer connected to a hydraulic cylinder. In certain embodiments, the property of a rhomboid mechanism is such that, by placing the shortest members of the rhomboid mechanism on a single line in the pressing cycle, it is possible to obtain a theoretically unlimited pressing force for the punch. In reality, the maximum value of the pressing force in this position is limited by the strength of the rhomboid mechanism members and the punch.

Fig.l ir parādīta piedāvātā mehānisma shēma. Mehānisms sastāv no statnes 1 un puansona 2, kuriem ir pievienots romboīda mehānisma garāko malu 3 šamīrs 4, bet īsāko malu 5 šamīrs 6 ir savienots ar hidrocilindru 7. Mehānisma darbība ir sekojoša: ievadot hidrocilindra 7 virzuļa telpā darba šķidrumu, notiek hidrocilindra izplešanās, iedarbojoties šamīrā 6 ar spēku F un mainot romboīda īsāko malu stāvokli tā, ka notiek leņķa ot samazināšanās. Vienlaicīgi notiek presējamās masas saspiešana, puansonam attīstot spēku P, kurš ir atkarīgs no masas saspiešanas pakāpes. Sakarībai starp hidrocilindra attīstīto spēku un puansona presēšanas spēku ir viennozīmīgs, bet nelineārs raksturs, kas ir atkarīgs no romboīda mehānisma stāvokļa. Pozīcijā, kurā a->0, iespējams ar nelielu spēku F iegūt teorētiski neierobežotu presēšanas spēku P. Pārslēdzot darba šķidruma pievadīšanu hidrocilindram 7 uz kāta telpu, notiek presēšanas puansona 2 atvirzīšana, un pēc gatavā presējuma aizvākšanas un jaunas presējamās masas iepildīšanas var notikt nākamais presēšanas cikls.Fig. 1 shows a schematic of the proposed mechanism. The mechanism consists of a strut 1 and a pouch 2 to which the longitudinal edge 3 of the rhomboid mechanism 3 is connected to the ram 4 and the short edge 5 of the ram 6 is connected to the hydraulic cylinder 7. The mechanism operates as follows: in shamir 6 with force F and changing the position of the short sides of the rhomboid so that the angle ot decreases. At the same time, the press mass is compressed by the force P being applied to the punch, which depends on the degree of mass compression. The relationship between the developed force of the cylinder and the punching force of the cylinder is unambiguous but nonlinear, depending on the position of the rhomboid mechanism. In the position where a-> 0, a theoretically unlimited pressing force P can be obtained with a small force F By switching the working fluid supply to the cylinder 7 into the shaft space, the pressing punch 2 is withdrawn and the next pressing can take place. cycle.

Piedāvāto hidrauliskās preses mehānismu ir ieteicams izmantot mobilās iekārtās, kur tā darbība var notikt, puansonam darbojoties dažādos slīpumos. Presēšana var tikt veikta slēgtā un arī nepārtrauktas plūsmas presformā, attiecīgi projektējot presējuma aizvākšanu un jaunas presējamās masas iepildīšanu.The proposed hydraulic press mechanism is recommended for use on mobile equipment, where it can operate on a wide range of inclines. Pressing can be carried out in a closed and continuous flow mold, designing the extraction of the press and the filling of a new press.
