Description

Technical Field

[0001] The utility model belongs to the technical field of pressure mechanical equipment, and specifically relates to a servo electric cylinder press. Background Art

[0002] The existing compressors include air compressors and gas-liquid boosters. An air compressor is a compressor that uses compressed air as a power source to push the cylinder; a gas-liquid booster is a device that uses a gas-liquid booster cylinder as an output device, and indirectly controls the oil pressure of the cylinder through air pressure. Since both air compressors and gas-liquid boosters are affected by the pressure of compressed air, and the compressed air must be filtered through a dryer before use, there are many types of equipment in the production workshop, and the compressed air pressure changes unstably, which seriously affects the press fitting accuracy of the press. The servo electric cylinder is a modular product design that integrates a servo motor and a mechanical transmission device. It has the characteristics of compact structure, fast response speed, strong overload resistance, and small space occupation. It is a new revolutionary product that can realize speed control, position control, etc. Utility Model Content
