Description

Изобретение относится к области обработки металлов давлением и может быть использовано в мощных вертикаль, ных гидравлических прессах.The invention relates to the field of metal forming and can be used in powerful vertical hydraulic presses.

Известен вертикальный гидравлический пресс,, содержащий станину, выполненную в виде неподвижных верхней и нижней поперечин, стянутых с промежуточной неподвижной плитой соответственно верхними и нижними колоннами, прос- * тавкн, установленные на нижних колоннах, а также рабочий цилиндр с буртом . и отъемным днищем,.A vertical hydraulic press is known, comprising a bed made in the form of fixed upper and lower cross-members, pulled together with an intermediate fixed plate by the upper and lower columns, respectively, spacer mounted on the lower columns, as well as a working cylinder with a shoulder. and detachable bottom.

Недостаток пресса заключается Й ТОМ, что он имеет невысокую жесткость, ненадежность и точность штампуемых деталей.The disadvantage of the press is that it has low rigidity, unreliability and accuracy of stamped parts.

С целью увеличения жесткости прессе» повышения надежности его работы и точности штампуемых изделий, проставки снабжены фланцами с отверстиями для верхних колонн, а отъемное днище и . бурт рабочего цилиндра размещены между верхней неподвижной поперечиной и неподвижной промежуточной плитой. ,In order to increase the rigidity of the press, to increase the reliability of its operation and the accuracy of stamped products, the spacers are equipped with flanges with holes for the upper columns, and a detachable bottom. the shoulder of the working cylinder is placed between the upper fixed cross member and the fixed intermediate plate. ,

На фиг. 1 схематически изображен пресс, продольный разрез; на фиг. 2 разрез А-А на фиг. 1.In FIG. 1 schematically shows a press, a longitudinal section; in FIG. 2, section AA in FIG. one.

Вертикальный гидравлический пресс, содержит станину, состоящую из верхней 1 и нижней 2 неподвижных поперечин. отцнутых колоннами верхнего 3 и нижнего 4 ярусов с неподвижной промежуточной плитой 5. Между нижней поперечиной 2 и промежуточной плитой 5 установлены проставки 6, каждая из которых одета на соответствующую колонну 4 нижнего яруса. Проставки 6 снабжены фланцами 7 с отверстиями для колонн 3 верхнего яруса, которыми проставки 6 жестко присоединены к промежуточной плите 5.A vertical hydraulic press contains a bed consisting of upper 1 and lower 2 fixed cross members. pressed columns of the upper 3 and lower 4 tiers with a fixed intermediate plate 5. Between the lower cross member 2 and the intermediate plate 5 spacers 6 are installed, each of which is dressed on the corresponding column 4 of the lower tier. Spacers 6 are provided with flanges 7 with holes for columns 3 of the upper tier, with which spacers 6 are rigidly attached to the intermediate plate 5.

В центральном отверстии промежуточной плиты 5 расположен рабочий цилиндр,, снабженный отъемным днищем 8 С уплотняем 9 и корпусом 10 с буртом 11, выполненным в'верхней части корпуса, конднищем 8. При корпуса 10 тактирующим с отъемным этом днище 8 и бурт 11 рабочего цилиндра расположёны между верхней поперечиной 1 и промежуточной плитой 5 и отянуты ими с помощью ко- : лонн 3 верхнего яруса.In the central hole of the intermediate plate 5, there is a working cylinder, equipped with a removable bottom 8 With a seal 9 and a body 10 with a shoulder 11 made in the upper part of the body, a tail 8. When the body 10 is in contact with the removable bottom 8 and the shoulder 11 of the working cylinder between the upper cross member 1 and the intermediate plate 5 and are drawn by them with the help of: columns 3 of the upper tier.

Claims

The invention relates to the field of metal forming and to be used in high-power vertical hydraulic presses. A vertical hydraulic press is known, which contains a bed, e in the form of fixed upper and lower crossbeams, installed with an intermediate fixed plate corresponding to the upper and lower columns, installed on the lower crust plates, and also a working cylinder with a collar. and a removable bottom. The disadvantage of the press is that it has low rigidity, unreliability and accuracy of the parts being stamped. In order to increase the rigidity of the press, increase the reliability of its work and the accuracy of the parts being stamped, the spacers are equipped with flanges with holes for the upper columns, and the detachable bottom and shoulder of the working cylinder are placed between the upper fixed crossbar and the fixed intermediate plate. , FIG. I schematically shows a press, a longitudinal section; in fig. 2, section A-A in FIG. 1, A vertical hydraulic press, contains a frame consisting of upper 1 and lower 2 fixed crossbars, detached from the columns of upper 3 and lower 4 layers with a fixed intermediate plate 5. Between the lower cross member 2 and intermediate plate 5, spacers 6 are installed, each of which is on the corresponding column 4 lower rus. Spacers 6 are provided with flanges 7 with holes d / 1) (olon 3 upper torsa, with which the sleeves 6 are rigidly attached to the intermediate plate 5. The working cylinder is located in the central hole of the intermediate plate 5 and is equipped with a removable bottom 8 With seal 9 and housing 10 with the collar 11, made the upper part of the body in contact with the detachable bottom 8. In this case, the bottom 8 and the collet 11 of the housing 10 of the working cylinder are located between the upper cross member 1 and the intermediate plate 5 and from them chute using the columns of the upper Rus 3, e body 10 working cyl Indra placed plunger 12 connected to the slider 13, on which the upper one is fixed (deformation tool 14, and the lower tool is placed on the lower crossbar 2; deformation ment 15. For the direction of the slider 13 along the spacers 6, the guides are made. force causes stretching of the columns 4 of the lower rus; at the same time, the bryock between T1 | eB (floor plate 5 th p e tus tam v стр rtrmc loosen. But the columns of the upper 3 PQ Yarush), installed with tension, compact these joints, because through the flanges 7 they press spacers 6 to: span When the plate TbyioT reciprocates the movement of the sealing elements 9 of the bottom of the working cylinder and the bed stiffness is maintained within the joint of the intermediate plate 5 with the spacers 6. Therefore, eccentric yugrueks arising from the stamping of the product 17 through the upper deformation tool 14, slider 13, guides 16, plunger 12 and body 10 are perceived by intermediate plate 5 and spacers 6 and do not cause re-use of the upper deformation tool 14, while ensuring high precision of the punching of the product 17.
