Изобретение относитс к обработке металлов и неметаллов давлением и может использоватьс при создании пневмо-гидравлических прессов.The invention relates to the processing of metals and non-metals by pressure and can be used to create pneumatic-hydraulic presses.

Известен пресс, содержащий нижнюю и верхнюю траверсы, ст нутые четырьм колоннами, закрепленный на нижней траверсе гидравлический цилиндр , подвижный стол, соединенный с плунжером цилиндра, насосы и гидравлическую аппаратуру управлени 1 .A press is known that includes a lower and upper cross member, four columns, a hydraulic cylinder fixed to the lower cross bar, a movable table connected to the cylinder plug, pumps and hydraulic control equipment 1.

Однако он имеет относительно сложную конструкцию, так как снабжен специальным насосным приводом и распределительной аппаратурой и,кроме того, должен иметь при мок дл рабочего цилиндра.However, it has a relatively complex structure, since it is equipped with a special pump drive and distribution equipment and, in addition, must have it for the working cylinder.

Наиболее близким по технической сущности к предлагаемому вл етс пресс, содержащий рабочий цилиндр, закрепленный в неподвижной плите, корпус, св занный с подвижной плитой, привод рабочего цилиндра, выполненный в виде установленного соосно сThe closest in technical essence to the present invention is a press comprising a working cylinder fixed in a fixed plate, a body connected to a movable plate, a drive of the working cylinder, made in the form of installed coaxially with

This press, unlike a hydraulic press, does not have a hydraulic drive 2.

Цель изрбретени - упрощение конструкции .The aim of the project is to simplify the design.

ISIS

Эта цель достигаетс тем. что в прессе, содержащем подвижную vi неподвижную плиты, плунжерный рабочий цилиндр и его привод, выполненный в виде соосно установленного и жестко This goal is achieved by those. that in a press containing a movable vi fixed plate, plunger working cylinder and its drive, made in the form of coaxially mounted and rigidly

Claims

20 connected with it a power piston cylinder with a rod in which a hole is made and a valve is installed, the working cylinder cavity and the rod cylinder cylinder cavity, the cylinder body is fixed and mounted on the foundation, and the movable plate is rigidly fixed on the plunger working cylinder. The drawing shows the press section. The press comprises a cylinder body 1 which is at the same time a support of the press. The top plate 2 is attached to the guide columns 3- The bottom plate k is movable and is attached to the plunger 5 in which the pusher 6 is located. The nipple 7 is designed to supply compressed air during the approach of the bottom plate. Pneumatically, the valve serves to limit the stroke of the bottom plate in the drawing. Not shown) In the piston rod 8 of the power cylinder, a valve 9i is installed necessary for closing the hole. The nipple 10 serves to supply compressed air during the working stroke of the bottom plate. The guard 11 is attached to the bottom plate. The guard 12 is attached to the cylinder body. The cylinder body is mounted on a foundation 13Press works as follows. An attachment is attached to the press plates, for example a mold into which the material is loaded (not shown). Compressed air is supplied to the nipple 7- Working fluid through the hole in the piston rod 8 of the power cylinder is displaced into the cavity of the working cylinder. Plunger 5 and bottom plate k are raised at low pressure. When compressed air is supplied to the nipple 10, the piston rod B of the power cylinder rises. Valve 9 closes the hole. The plunger 5 raises the lower plate k at high pressure, and there is a working stroke of the press. After the required holding time, the nipple 10 communicates with the atmosphere, the lower plate C is lowered under its own weight and 2 additional cylinders (not shown in the drawing). The products are pushed out by the pusher 6. Then the cycle repeats. The proposed design is simple and reliable in operation. Claims of the Invention A press comprising a movable and fixed plate, a plunger working cylinder and its drive, made in the form of a coaxially mounted and rigidly connected power piston cylinder with a rod in which a hole is made and a valve separating the cavity of the working cylinder and the rod cavity is installed cylinder, characterized in that, in order to simplify the construction, the cylinder body is fixed and mounted on the foundation, and the movable plate is rigidly fixed on the plunger of the working cylinder.
