Description

Power-driven threading die device for thread forming and quick repairing

Technical Field

The utility model relates to the technical field of machining, in particular to a power-driven threading die device for thread forming and quick repairing.

Background

The screw rods serve as key components of the power transmission line tower foundation and play a critical role, and the main functions and characteristics of the screw rods are that firstly, the screw rods are important bearing components of the power transmission line tower foundation, are pre-buried underground and tightly combined with soil or rock to provide stable support for the whole tower body, and the strength and stability of the screw rods directly influence the safety and reliability of the tower body. Second, the design of the screw takes into account a variety of environmental factors, for example, in areas where geological conditions are complex, the screw needs to be of sufficient length and diameter to ensure penetration into a stable soil or rock formation. Meanwhile, the materials of the screw are carefully selected to resist the corrosion of groundwater and the corrosion of chemical substances in soil. In addition, the screw is also one of its characteristics, and they are usually connected and fixed with the tower structure and other basic components by specific processes and equipment, and this connection ensures the stability of the tower and is convenient for maintenance and replacement in future. In the design of the transmission line tower foundation, the arrangement and the number of the screws are also precisely calculated. Depending on the height, weight and external loads of the tower, such as wind, earthquakes, etc., the engineer may determine the appropriate number and location of screws to ensure the overall stability of the tower. Finally, the screws are also important for maintenance and inspection as part of the transmission line tower foundation. The screw is regularly checked and maintained, and potential problems such as abrasion, corrosion or loosening can be timely found and processed, so that safe and stable operation of the power transmission line is ensured. However, the threads of the screw often wear or even fail during use, and the wear of the threads is often the result of a combination of factors including, but not limited to, (1) friction, which can cause wear during the threaded connection or rotation, between the threads and the mating member. Such galling can gradually destroy the accuracy and shape of the threads, degrading their performance. (2) Load-threads, when subjected to load, particularly repeated or excessive loads, can cause fatigue and spalling of the material of the thread surface. Such galling progressively deepens the grooves of the threads, affecting the strength and tightness of the threads. (3) Corrosion-chemical substances in the environment or humid conditions may cause corrosion of the threaded surfaces. Corrosion can damage the surface structure of the threads, accelerate the galling process, and can lead to failure of the threads. (4) Improper operation, when installing, removing or adjusting a threaded connection, may result in damage or deformation of the threaded surface if not operated in the correct way or tool.

It should be noted that the wear of the threads is a progressive process, so timely detection and taking of precautions is critical to extending the service life of the threads. If the threads have been significantly worn or damaged, repair or replacement should be performed in time.

Since the screw belongs to the embedded part and cannot be replaced, it may be located deep in the equipment or structure, and other installed parts may be around, which makes maintenance work complicated and difficult. Meanwhile, the equipment and the bracket are installed and disassembled, so that the screw thread needs to be repaired and corrected. However, because the handle of the conventional threading die apparatus is too long, there is interference with the equipment rack, which may not only cause operational difficulties, but also cause unnecessary damage to the equipment rack, as shown in fig. 1. While effective in solving the interference problem with the equipment support, shortening the handle length of the die assembly may have other negative effects, including, among other things, shortening the handle may reduce the overall length of the assembly, thereby affecting its structural strength and stability. Too short a handle may not provide sufficient support and torque, resulting in the device being prone to jolt or deformation during maintenance, reducing the accuracy and efficiency of operation. Second, the length of the handle determines to some extent the operating range of the operator. If the shank is too short, it may not allow the operator to effectively use the die assembly at certain angles or locations, thereby limiting its range of application and flexibility. Also, in certain circumstances, a longer handle may help operators better control the device, particularly when greater torque needs to be applied or more precise operation is desired. Shortening the handle length may make these operations more difficult, increasing maintenance difficulties and time costs. Existing equipment supports and fixtures may both be sized based on conventional die set. After shortening the shank length, the newly designed die set may be incompatible with existing equipment supports and fixtures, requiring additional adaptations or modifications.
