Product Specifications

Technical details and manufacturing context for Stopper Insertion Cylinder

Definition

The Stopper Insertion Cylinder is a hydraulic cylinder component used in machinery and equipment manufacturing, specifically within a Hydraulic Stoppering System. Its primary function is to provide precise linear force and motion to insert stoppers, plugs, or caps into containers or production line fixtures. The cylinder ensures controlled insertion depth and pressure, which is critical for achieving proper sealing and maintaining product integrity.

This component operates by converting hydraulic pressure into linear mechanical force. Hydraulic fluid is directed into the cylinder barrel, causing a piston to move. The piston rod, connected to the stopper insertion mechanism, extends or retracts to perform the insertion action. The working principle relies on the incompressibility of hydraulic fluid, allowing for accurate control of force and speed.

Key specifications for this cylinder include an operating pressure range of 1.0–1.6 MPa, a bore diameter of 40–100 mm (per ISO 6020-2), and a stroke length of 50–300 mm (per ISO 6020-2). The insertion force ranges from 1.5 to 12 kN, and positioning accuracy is ±0.05 mm. The operating temperature range is -20 to 80°C, and the ingress protection rating is IP54–IP65 (per IEC 60529). The cylinder material is 6061-T6 aluminum (per ASTM B221), and the piston rod is made of 45# steel (per GB/T 699) with hard chrome plating. The weight ranges from 5 to 25 kg.

Materials on file include chrome-plated steel and sealing elastomers. These materials contribute to corrosion resistance and sealing performance. The cylinder is designed for use in applications where precise stopper insertion is required, such as in pharmaceutical, food and beverage, or chemical packaging lines.

When selecting a Stopper Insertion Cylinder, it is essential to verify model-specific values and standards with the legal manufacturer or supplier. The parameters listed are reference ranges and must be confirmed for the actual application. Proper installation, alignment, and maintenance are crucial for reliable operation. Regular inspection of seals and rod condition is recommended to prevent leaks and ensure consistent performance.

Working Principle

The Stopper Insertion Cylinder converts hydraulic pressure into linear mechanical force. Pressurized hydraulic fluid enters the cylinder barrel, acting on a piston. The piston moves, extending or retracting the piston rod, which is connected to the stopper insertion mechanism. The direction and speed of movement are controlled by the hydraulic system, allowing precise positioning and force application. The cylinder's bore diameter and stroke length determine the force and travel distance, while the operating pressure influences the insertion force. Sealing elastomers prevent fluid leakage, and the chrome-plated steel rod resists wear and corrosion.
