3results about How to "Avoid affecting normal work" patented technology

This utility model provides a hydraulic cylinder with internal self-cleaning filtration, including a cylinder body, a piston rod, a mounting bracket, and a cleaning assembly. The surface of the mounting bracket is fixedly connected to one side of the cylinder body. One end of the piston rod passes through the mounting bracket and the cylinder body sequentially and extends into the interior of the cylinder body. A working piston is fixedly connected to the end of the piston rod located inside the cylinder body. A connecting support rod is fixedly connected to the surface of the mounting bracket. A mounting sleeve is fitted onto the surface of one end of the connecting support rod. A connecting rod is fixedly connected to the surface of the mounting sleeve. A return box is fixedly connected to the surface of the mounting sleeve via the connecting rod. The inner wall of the return box is concave. A return pipe is connected to the bottom of the return box. The bottom end of the return pipe is connected to the surface of the cylinder body. By setting up the cleaning assembly, the entire system achieves the function of filtering hydraulic oil, avoiding affecting the normal operation of the hydraulic cylinder and ensuring the efficiency of the hydraulic cylinder.

The application discloses a production process and a production device of a high-pressure-resistant, low-temperature-resistant and corrosion-resistant austenitic seamless stainless pipe for aerospace, and the production process comprises the following steps: raw material preparation, cutting, heating treatment, rolling forming, heat treatment, cooling treatment, straightening treatment, surface treatment, quality detection and packaging and warehousing, and the production equipment used in the cooling treatment step comprises a comprehensive billet cooling box, a load driving hydraulic cylinder, a billet air cooling conveyor and a medium cooling conveying claw. The application has four cooling treatments of water quenching, oil quenching, gas quenching and air cooling, the cooling conveying assembly mechanism makes the billet have two conveying routes, can better make the billet synchronously cooled in two cooling modes of liquid medium cooling and gas medium cooling in different modes, prevents the cooling treatment of the latter billet from being affected by the former billet, and improves the free flexibility of the cooling process operation.

The present application relates to cold extrusion equipment technical field, specifically to a kind of cold extrusion synchronous control device of asymmetric ferrule blank, including rack, forming device, multiple forming devices are provided on the rack, multiple forming devices are arranged along vertical direction obliquely, and the forming device includes extrusion mechanism and mould.The present application is inclinedly arranged along vertical direction to multiple forming devices, and guide rail is arranged on rack, so that ferrule blank can be moved to next forming device by its own gravity, and by the setting of feeding disc, ferrule blank can be aligned with the die cavity of mould by the rotation of motor, and then ferrule blank is pushed into the die cavity of mould by extrusion mechanism, so as to reduce the setting of intermediate handling equipment, so as to reduce the cost of production line, and the synchronous control device has high synchronism, and will not affect the processing rhythm of multi-step extrusion, effectively improve the working efficiency of ferrule blank cold extrusion.
