Description

Technical Field

[0001] This utility model relates to the technical field of lubrication and cooling devices for cold-drawn steel pipes, and in particular to a lubrication and cooling device for cold-drawn steel pipes. Background Technology

[0002] Cold-drawn steel pipes are seamless steel pipes manufactured through cold working processes (stretching, extrusion, or piercing at room temperature). In the field of cold-drawn steel pipe processing, traditional processes employ separate cooling and lubrication devices: the steel pipe is first cooled by spraying and then transported to the lubrication station, where lubricant is applied manually or by immersion in a bath. This method has significant drawbacks: 1. Process interruption: The temperature of the steel pipe rises after cooling, causing the lubricant to evaporate and become ineffective, requiring secondary cooling, which increases energy consumption by more than 30%; 2. Insufficient precision: Manual operation leads to uneven lubrication layer thickness, causing scratches on the steel pipe surface during the cold drawing process. 3. Low efficiency: Transfer intervals cause the production line cycle time to be extended, and the processing time for a single steel pipe is long. Utility Model Content

[0003] To overcome the shortcomings of existing devices, this invention provides a lubrication and cooling device for cold-drawn steel pipes.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a lubrication and cooling device for cold-drawn steel pipes, including a workbench and a feeding cooling system and a lubrication system installed on the workbench; the feeding cooling system includes a conveyor line and a spray cooling unit, the conveyor line is set on the upper surface of the workbench, the spray cooling unit is arranged directly above it, and the lubrication system is arranged to its side; the lubrication system includes a clamping actuator and a lubrication actuator; the clamping actuator includes a horizontal displacement cylinder, an axial displacement cylinder and a pneumatic gripper; the moving direction of the horizontal displacement cylinder is parallel to the conveying direction of the conveyor line, and the axial displacement cylinder is connected to its slider; two sets of pneumatic grippers are symmetrically arranged on the slider of the axial displacement cylinder. The lubrication actuator includes a gripper; it comprises a rotary disk, a rotary sponge adsorption roller, a lubricant spraying unit, a support roller assembly, and a pipe clamping unit. The rotary disk is located downstream of the axial displacement cylinder, and has several sets of rotary sponge adsorption rollers evenly distributed around its circumference. The pipe clamping unit is located directly above the rotary disk. The support roller assembly is fixed upstream of the axial displacement cylinder mounting base, and its surface is provided with supporting rollers corresponding to the positions of the rotary sponge adsorption rollers.

The clamping actuator is simultaneously moved to the lubrication station, preventing the temperature from rising again. 2. High-precision lubrication control: The rotary sponge adsorption roller and the support roller assembly form a flexible contact area with a wrap angle of 120°, which improves the lubricant penetration rate; 3. Improved efficiency through dynamic coordination: The linkage between the horizontal displacement cylinder and the axial displacement cylinder improves the positioning accuracy of the transfer. The circumferential station design of the rotary table reduces the processing time of a single steel pipe. The lubricant injection unit provides quantitative supply, reducing consumption. 4. Adaptive pipe diameter coverage: The pipe clamping unit works in conjunction with the supporting rollers, and the rotating sponge adsorption roller has elastic and stretchable sponge, which is compatible with various types of pipe diameters.
