This feed cylinder is an auxiliary actuator for industrial press-forming equipment, typically mounted at the powder feeding station or material stop positioning mechanism. It extends and retracts smoothly over a long 800 mm stroke to perform quantitative powder feeding, workpiece transfer, or material stop positioning. A small-bore, long-stroke lightweight design (63 mm bore, 800 mm stroke) delivers 62 kN of thrust and 43 kN of pull. Combined with a high-strength alloy steel barrel, a precision hard-chrome plated piston rod, low-friction composite seals, and bidirectional cushioning, it ensures stable, stick-slip-free, low-leakage linear motion under dusty, oily, and high-cycle conditions — a key auxiliary component for the automated continuous production of press-forming equipment.

This auxiliary cylinder is a companion actuator for industrial press-forming equipment, typically installed on the ejector mechanism, floating platen control, or side-pressing station. Its functions include part ejection, mold floating control, lateral auxiliary pressing, or platen balance adjustment. Built on a 150 mm bore, 640 mm stroke platform, it delivers 353 kN of thrust and 291 kN of pull — a near-balanced bidirectional capability that makes it particularly suited for alternating push-and-pull cycles such as ejection and retraction. Combined with a high-strength alloy steel barrel, a precision hard-chrome plated piston rod, multi-stage seals, and bidirectional cushioning, it ensures long-term stable, leak-free reciprocating motion under dusty, high-temperature, and high-cycle conditions.

This main cylinder is the core drive element of industrial press-forming equipment such as powder compacting presses, tablet presses, or composite material presses. Mounted between the frame and the moving platen or slider, it extends and retracts with powerful hydraulic thrust to perform long-distance, high-tonnage pressing and return strokes, completing critical processes like powder compaction, hot pressing, or mold clamping. A long-stroke, high-thrust design (180 mm bore, 1,450 mm stroke, 509 kN push force), combined with a high-strength alloy steel barrel, a precision hard-chrome plated piston rod, multi-stage seals, and bidirectional cushioning, ensures stable, leak-free high-pressure operation under dusty, high-temperature, and heavy cyclic shock conditions — a key component for product forming quality and press production rates.

This master cylinder is the absolute heart of ultra-large forging press lines. Vertically installed at the center of the press crown, it extends its super-large-diameter plunger under high-pressure hydraulic oil to apply up to 80 MN of main forging force, driving the moving crosshead and upper anvil against the workpiece. It is used for upsetting, drawing, piercing, and closed-die forming in open-die, die-forging, and multi-directional forging processes. The single-acting plunger design features a maximum plunger diameter of 1,800 mm, making it one of the world’s most powerful hydraulic cylinders. Integrated wide bronze guide bushings, multi-layer V-pack seals, built-in magnetostrictive displacement sensors, and a progressive cushioning system, together with super-nut locking and optional booster cylinders/rotary unions, provide extremely smooth, precise, and long-lived main thrust output under the sustained extreme loads, radiant heat, and hammer-vibration conditions of industrial forging plants — truly the unbeating heart of 5,000-tonne-class and larger presses.

This side cylinder is one of the core power elements of ultra-large forging press lines. Symmetrically mounted on either side of the main cylinder, it works together with the main cylinder to apply downward forging force on the moving crosshead. In large open-die and die-forging operations, when the main cylinder alone cannot provide sufficient force, the side cylinders synchronously engage, each delivering up to 24.7 MN of thrust. Together they form the combined force necessary for upsetting, drawing, or closed-die forming of heavy cross-section billets. A super-large-diameter plunger design (up to 1,000 mm) integrates wide bronze guide bushings, a replaceable V-pack sealing system, built-in magnetostrictive displacement sensors, and super-nut locking, delivering stable, precise, synchronous thrust under sustained extreme loads, intense heat radiation, and heavy hammer vibration — making it an indispensable asset for 5,000-tonne-class and larger presses.

This return cylinder (plunger type) is a dedicated auxiliary power element working alongside the main cylinder and side cylinders in forging press lines. Typically mounted symmetrically beneath the moving crosshead or on the press bed, it uses high-pressure hydraulic oil to extend its large-diameter plunger upward, briskly and steadily lifting the multi-hundred-tonne moving crosshead back to its starting position for the next forging stroke. A single-acting plunger design delivers extremely high thrust (up to 3,206 kN) with a long stroke (up to 3,000 mm). Wide bronze guide bushings, a V-pack seal system, and built-in displacement sensors ensure stable, precise, zero-leakage return force even under sustained high temperatures, intense vibration, and high-cycle impacts. Compared with piston types, plunger-type return cylinders are simpler in construction and easier to maintain, making them especially suitable for the confined spaces of large open-die and die-forging presses.

This return cylinder (piston type) is a critical auxiliary power element in forging press lines. Mounted at the press crown, moving crosshead, or side-cylinder bracket, it retracts its piston rod to raise the moving crosshead quickly and smoothly back to its initial position, preparing the press for the next forging stroke. Compared with plunger-type return cylinders, the piston design delivers both strong pulling force (for retraction) via its annular area and, when needed, pushing force (for assisted stripping or controlled lowering), enabling more complex motion cycles. A long-stroke double-acting design with up to 2,612 kN of pulling force integrates wide bronze guide bushings, a replaceable V-pack sealing system, built-in magnetostrictive displacement sensors, and super-nut locking. Under the sustained heat radiation, intense vibration, and heavy offset loads typical of forging, it provides precise, reliable, zero-leakage return performance — a key guarantee for the efficient and safe operation of large open-die and die-forging presses.

This lateral shift anvil cylinder is a key auxiliary actuator in forging press lines. Installed between the press base and the lower anvil or anvil slide, it hydraulically moves the anvil transversely (in/out) to enable rapid anvil changeover and flexible positioning for multi-step forging operations. A double-acting piston design with an extra-long stroke (up to 5,500 mm) delivers a maximum thrust of 1,546 kN. Wide bronze guide bushings, a replaceable V-pack sealing system, an integrated magnetostrictive displacement sensor, and super-nut locking ensure precise anvil positioning, reliable zero-leakage performance, and long service life under the combined effects of heat radiation, hammer vibration, and the heavy offset loads of moving anvils—greatly improving anvil-changing efficiency and forging flexibility.

This mobile workbench cylinder is a critical auxiliary actuator in forging press lines. Mounted between the press base and the mobile workbench, it hydraulically moves the workbench along guide rails into and out of the pressing station, enabling rapid changeover of upper and lower anvils, billet loading/unloading, and flexible switching between multi-step forging operations. A double-acting, ultra-long-stroke piston design (up to 7,500 mm) integrates wide bronze guide bushings and a replaceable V-pack sealing system, delivering up to 2,533 kN of thrust and pull while withstanding the side loads and inertial shocks of heavy workbench movement. Built-in magnetostrictive displacement sensors enable multi-cylinder synchronized closed-loop positioning. Together with super-nut locking, optional booster cylinders, and rotary unions, it is ideally suited for large-tonnage open-die and die-forging press lines, significantly reducing auxiliary time and boosting forging productivity.

This clamping cylinder is a critical actuator for the manipulator in open-die forging press lines. Mounted at the front of the manipulator's tong rod or within the clamp head mechanism, it extends and retracts its piston rod to close or open the jaws, securely gripping the hot steel ingot or billet on the anvil. A high-thrust double-acting piston design delivers up to 9,621 kN of clamping force. With wide bronze guide bushings, a V-pack sealing system, built-in displacement sensors, and super-nut locking, it provides absolutely reliable, leak-free, high-response clamping performance under the continuous heat radiation, intense hammer vibration, and frequent cycling of forging operations, significantly improving both forging rhythm and operational safety.

This leveling cylinder is a vital actuator for the manipulator in open-die forging press lines. Installed in pairs or sets between the manipulator arm and tong carriage, it synchronously extends or retracts its piston rod to achieve parallel raising or lowering of the clamp head or workpiece platform, enabling precise height adjustment of the billet between the upper and lower anvils. A double-acting heavy-duty piston design integrates wide bronze guide bushings and a replaceable V-pack sealing system, delivering up to 2,835 kN of lifting force while withstanding multi-directional side loads from workpiece eccentricity and manipulator vibration. Built-in magnetostrictive displacement sensors enable multi-cylinder synchronized closed-loop control, and with super-nut locking, optional booster cylinders, and rotary unions, it is ideally suited for high-cycle, high-precision open-die and die-forging lines, significantly improving the accuracy and reliability of workpiece attitude adjustment.

This tilt cylinder is a core actuator for the manipulator in open-die forging press lines. Mounted between the manipulator arm and the tong carriage, it extends or retracts its piston rod to tilt the clamp head up and down, adjusting the workpiece angle on the anvil and enabling multi-step forging coordination. A double-acting heavy-duty piston design integrates wide bronze guide bushings and a V-pack sealing system, producing up to 3,141 kN of thrust while withstanding multi-directional side loads from workpiece eccentricity and manipulator vibration. Built-in displacement sensors enable closed-loop position control, and with super-nut locking, optional booster cylinders, and rotary unions, it is ideally suited for high-cycle, high-precision open-die and die-forging lines, dramatically improving the accuracy and reliability of manipulator attitude adjustment.
