The present invention discloses a special hydraulic press for bulging pressing forming of an automobile axle housing and a pressing forming method. A hydraulic press body is a closed frame consisting of an upper cross beam, a lower cross beam, four stand columns I, II, III, and IV, four vertical pull rods I, II, III, and IV, and four transverse pull rods I, II, III, and IV, and is used for balancing a deformation force up to 3000 T in the vertical direction or the horizontal direction in the pressing forming process. During pressing forming, the downward speeds of a main hydraulic cylinder, small left and right vertical hydraulic cylinders are precisely controlled to prevent the left end, the right end and the middle of the tube blank from bending.

A tablet discharge gate for a tablet press comprises a tablet channel having an inlet and an outlet and comprising one of a tube shape and a trough shape, a first outlet channel, and a second outlet channel. A gate chamber is positioned between the outlet of the tablet channel and the first and second outlet channels. A drive apparatus is configured to move the tablet discharge gate between a first position in which tablets are supplied from the tablet channel to the gate chamber and into the first outlet channel of the gate, and a second position in which tablets are supplied to the tablet discharge gate chamber and into the second outlet channel.

Compaction press includes a support structure provided with an abutment surface; a first compaction lid, which is provided with a first flat compaction surface and is rotatably constrained to a first delimitation edge of the support structure; a second compaction lid, which is provided with a second curved compaction surface and is rotatably constrained to a second delimitation edge of the support structure. The abutment surface of the support structure and the first and second compaction surfaces of the first and second compaction arms delimit a pressing chamber, in which a mass of material to be compacted is intended to be deposited. In addition, the second compaction lid includes a first arm and a second arm which are rotatably constrained to each other.

A press apparatus for forming molded products is provided and includes a motive source and a press assembly in fluid communication with the motive source. The press assembly includes a press plate and a device configured to actuate axial movement of the press plate. A mold base is positioned within the press assembly and configured for engagement with the press plate. The mold base includes a plurality of mold cavities and each of the mold cavities includes a mold cavity aperture. Each of the mold cavity apertures is arranged in a pattern and configured to provide access to a molded product positioned in a mold cavity. A release assembly is configured for engagement with the mold base and has a plurality of release fingers, each extending from a base plate. The plurality of release fingers is arranged in a pattern that aligns with the pattern of the mold cavity apertures.

A hydrostatic/hydrodynamic fluid bearing assembly for a can bodymaker is provided. The hydrostatic/hydrodynamic fluid bearing assembly is separate from the ram body. The outboard guide bearing assembly includes a carriage assembly and a number of elongated journals. The carriage assembly includes a ram coupling, a crank coupling, and body defining a number of journal passages. The ram body is coupled to a ram coupling. The crank coupling is structured to be coupled to a crank arm. Each journal extends through a carriage assembly body journal passage. In this configuration, the ram body may form a can body in a traditional manner, but fluid bearing assembly fluid is not applied to the ram body. Instead, the fluid bearing assembly fluid is applied to the journals.

A press ram for a fine blanking press comprises a ram plate section configured to carry a fine blanking tool and at least two guide sections positioned on opposing sides of the ram plate section. The ram plate section comprises an upper surface, a lower surface, and two opposing side surfaces. The at least two guide sections of the ram plate section are configured to guide movement of the press ram relative to a press frame during a fine blanking process. The at least two guide sections extend in a vertical direction to a level that is higher than the upper side of the ram plate section.

A heavy-duty press is a mechanical machine used for compressing various parts and can be used for forging, molding, blanking, punching, deep drawing and many other applications. The force is generated by the use of hydraulic fluids based on Pascal's principle. The Press With Center Hole Hydraulic Cylinders simplifies the press design by using center hole hydraulic cylinders installed on the mobile platen with the press column inside the center hole. Center hole hydraulic cylinders being connected directly to the column eliminate the need of the third platen. A press with only two platens is cheaper and does not need large pits to be installed in. Also the design of the Press With Center Hole Hydraulic Cylinders use columns made of small section of hexagonal heat-treated steel bars arranged in an array forming a larger column of hexagonal shape. Columns made of small heat-treated bars are stronger, better connected to other press components and are much easier to fabricate and install.

Provided is a workpiece holding tool changing system configured to change at least one of a relative position and a posture of a holding tool of a workpiece conveying apparatus with respect to a feed bar. The feed bar includes at least one set among: an X-axis direction linear mechanism with an X-axis linear brake; a Y-axis direction linear mechanism with a Y-axis linear brake; a Z-axis direction linear mechanism with a Z-axis linear brake; and a ball joint portion and a ball brake. Under a state in which inhibition of movement or change in posture by a corresponding brake is canceled, a robot changes the relative position or the posture of the holding tool to a desired relative position or a desired posture. After the change, the workpiece holding tool changing system is brought into a holding state in which the movement or the change in posture is inhibited.

A link press assembly for use with a press to service a parallel link track chain is provided that includes alignment tools, disassembly tools, and reassembly tools. The alignment tools include a contact block, a plurality of block guide rods slidingly receivable within block guide rod passages of the contact block, a bridge plate for securement to a parallel link track chain, a plurality of elongated rod guides having plate guide rod passages, and a support block. The disassembly tools include a disassembly mount plate, an inner link support plate, a plurality of disassembly rods, an outer link support plate, and a disassembly tool bar having a plurality of pin bumpers. The reassembly tools include a back tool plate, a plurality of backing cups, a reassembly front tool bar having a plurality of front cups secured thereto, and a link hanger having a plurality of hanger guide rod passages.
