5results about How to "Improve pipe penetration efficiency" patented technology

The invention relates to the technical field of heat preservation pipes, in particular to a polyurethane heat preservation pipe heat preservation layer manufacturing process which comprises the following steps that S1, a conveying pipe penetrates through a protection pipe, the two ends of the protection pipe are connected with the conveying pipe through a support, and the protection pipe and the two ends of the conveying pipe are in a concentric state; the material injection opening is formed in the protection pipe, and then the fixing frame is arranged on the conveying pipe. The outer wall of the protection pipe is fixed after pipe penetrating, so that the problem that the thickness of a manufactured heat preservation layer is not uniform due to the fact that the protection pipe is eccentric due to the fact that the protection pipe collapses under the action of gravity is avoided, and therefore on the premise that the use of a wood block support is reduced, the concentricity of the protection pipe and the conveying pipe can still be guaranteed, and the uniformity of the heat preservation layer is guaranteed; in this way, the service life of the polyurethane thermal insulation pipe is prolonged, use of wood block supports is reduced, pipe penetrating can be more convenient, and the manufacturing efficiency of a thermal insulation layer of the polyurethane thermal insulation pipe is effectively improved.

The application discloses a heat exchange pipe threading device and relates to the technical field of heat exchange pipe threading equipment. The heat exchange pipe threading device comprises a feeding mechanism, a baffle fixing mechanism and an end plate fixing mechanism. The feeding mechanism comprises a frame body, a driving assembly and a conveying assembly, and the conveying assembly comprises a clamping part and a plurality of supporting parts. The baffle fixing mechanism comprises a moving frame, a first supporting frame and a second supporting frame, and the second supporting frame is provided with a supporting part and a plurality of pressing parts. The end plate fixing mechanism comprises a fixing frame, a baffle and a plurality of supporting blocks, and the supporting blocks are connected with the fixing frame through first lead screws. The feeding mechanism can be used for flexibly adjusting the position and height of the heat exchange pipe, assisting workers in pipe threading operation, effectively improving pipe threading efficiency, and adapting to different types of components through the baffle fixing mechanism and the end plate fixing structure, so that the components can be clamped and workers can conveniently perform pipe threading operation.

In conclusion, the utility model has the advantages that pipe threading is smooth, heat exchange tube is not damaged, and pipe threading efficiency can be improved.

This utility model relates to the field of wire production technology and discloses a wire threading device for production equipment, including a workbench. A motor is fixedly installed on one side of the workbench via a mounting bracket. A rotating shaft is fixedly sleeved on the output shaft of the motor and rotatably connected to the middle of the inner wall of the workbench. Several main conveying wheels are fixedly sleeved on the surface of the rotating shaft. A first top plate is fixedly installed at the top center of the workbench, and several guide columns are slidably connected inside the first top plate. This utility model forms an upper and lower clamping structure with the driven wheel and the main conveying wheel, which not only provides conveying power but also stabilizes the wire posture, preventing the wire from bending or jumping due to uneven force during conveying, thus improving the threading stability. By using a spring to push the driven wheel to press on the wire, the pressure can be automatically adjusted according to the wire diameter to ensure that wires of different specifications can obtain sufficient friction, avoid slippage, and improve the flexibility of the device.

The utility model discloses a pipe penetrating tool for a self-coiling braided pipe. The pipe penetrating tool comprises a mounting seat, a sleeve and a connecting column, the mounting seat is fixedly arranged; the front end of the sleeve is provided with a conical pipe penetrating part, the rear end of the sleeve is provided with a connecting hole matched with the pipe diameter of a wire harness to be processed, and the wire harness to be processed is connected with the sleeve by being oppositely inserted into the connecting hole; and one end of the connecting column is fixedly connected with the mounting seat, and the other end of the connecting column is fixedly connected with the sleeve and is arranged in the radial direction of the sleeve, so that when the conical pipe penetrating part penetrates through the self-coiling braided pipe, the two free edges of the self-coiling braided pipe are automatically separated. According to the utility model, the rapid connection with the wire harness of the self-coiling braided tube to be penetrated and the rapid insertion into the braided tube are realized through the sleeve, the overall structural design is simple, the tube penetration step of the self-coiling braided tube is simplified, and the tube penetration efficiency is improved.
