Electro-hydraulic Push Rod for Steel Wire Drawing, Electric Actuator, Hydraulic Cylinder
Section 1: The electric push rod is composed of components such as the motor, reduction gears, screw, copper nut, guide sleeve, piston rod, bearing housing, bearing housing, spring, cylinder seat, connecting fork, and photoelectric proximity switch unit (optional by the user).
Two、2Operating Principle:
Three The motor drives the ball screw nut after being reduced by one or two stages of gears, converting the motor's rotational Dynamic conversion to linear motion, beneficial Actuating the push rod in reciprocating motion through forward and reverse operation of the motor. Output push-pull force is equal. By adjusting the lever arm lengths, stroke length can be increased. 3Overload automatic protection feature:
FourElectromagnetic rod overload automatic protection device, when the rod stroke reaches Location or load exceeding rated thrust Numeric value, push rod The power supply will automatically be cut off, serving as a protective measure to prevent damage to the motor and other components; however, this should not be used as a limit during normal operation. Position switch usage requires an additional external stroke limit switch device to be configured on the machine. Our factory can provide photoelectric proximity switch configurations for customers. Positioning to control the rod's normal start and stop.
One,Principles and Functions
1、Operation Principle: The electro-hydraulic push rod is powered by an electric motor, which, through forward (or reverse) rotation, drives hydraulic oil to be output as pressure oil via a bidirectional gear pump. The oil then flows through an integrated oil block to the working cylinder, thereby achieving reciprocating motion of the piston rod.
2、Overload Automatic Protection Function: During the operation of the electro-hydraulic push rod, if the external force on the piston rod exceeds the rated output force or the piston reaches the end position, the motor continues to rotate. At this point, the oil pressure in the oil circuit increases to the set pressure, and the overflow valve rapidly and accurately overflows, achieving overload automatic protection. Although the motor is rotating, it will not be damaged.
3、Self-locking Function: The hydraulic circuit module of the electro-hydraulic push rod is designed with a hydraulic self-locking mechanism, so when the motor stops, the piston rod immediately stops. The pressure oil is in a pressure-holding state at its position.
4、Speed can be infinitely adjusted within the designated speed range as per customer requirements.
5、Provide continuous adjustment of push and pull forces within the designated output power range.
6、The travel range can be infinitely adjusted via electric control within the designated range.
7、Electromagnetic actuators are currently categorized by their rated thrust.12 grades ranging from 25 to 30,000 kg, with travel lengths of 100 to 1300 mm, each with 42 or 84, 50 or 100, and 26.6 or 53.2 speed options.
