Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a power-driven die device for thread forming and rapid repair. Background Art

[0002] As a key component of the transmission line tower foundation, screw rods play a vital role. Their main functions and characteristics are reflected in the following aspects: First, screw rods are important load-bearing components of the transmission line tower foundation. They are pre-buried underground and tightly combined with soil or rock to provide stable support for the entire tower body. The strength and stability of the screw rods directly affect the safety and reliability of the tower body. Secondly, the design of the screw rods takes into account a variety of environmental factors. For example, in areas with complex geological conditions, the screw rods need to have sufficient length and diameter to ensure that they can penetrate into stable soil or rock layers. At the same time, the material of the screw rods is also carefully selected to resist corrosion from groundwater and erosion by chemicals in the soil. In addition, the installation and fixing method of the screw rods is also one of its characteristics. They are usually connected and fixed to the tower structure and other basic components through specific processes and equipment. This connection method not only ensures the stability of the tower body, but also facilitates future maintenance and replacement. In the design of the transmission line tower foundation, the arrangement and number of screw rods are also accurately calculated. Based on the height and weight of the tower and the external loads such as wind and earthquake, engineers will determine the appropriate number and position of screws to ensure the overall stability of the tower. Finally, as part of the foundation of the transmission line tower, the maintenance and inspection of the screws are also very important. Regular inspection and maintenance of the screws can timely detect and deal with potential wear, corrosion or loosening problems, thereby ensuring the safe and stable operation of the transmission line. However, the threads of the screws often wear or even fail during use. The wear of the threads is usually the result of the combined action of multiple factors, including but not limited to the following: (1) Friction: During the threaded connection or rotation process, the friction between the threads and between the threads and the mating parts will cause wear. This wear will gradually destroy the accuracy and shape of the threads and reduce their performance. (2) Load: When the threads are subjected to load, especially repeated or excessive loads, they will cause material fatigue and peeling on the thread surface. This wear will gradually deepen the groove of the thread, affecting the strength and sealing of the thread. (3) Corrosion: Chemical substances or humid conditions in the environment may cause corrosion on the thread surface. Corrosion will destroy the surface structure of the thread, accelerate the wear process, and may cause thread failure. (4) Improper operation: When installing, disassembling or adjusting threaded connections, if the correct methods or tools are not used, damage or deformation of the thread surface may occur.

[0003] It should be noted that thread wear is a gradual process, so timely detection and preventive measures are essential to extend the service life of the thread. If the thread has been significantly worn or damaged, it should be repaired or replaced in time.

[0004] Since the screw is an embedded part that cannot be replaced, it may be located deep in the equipment or structure, and there may be other installed parts around it, which makes maintenance work complicated and difficult. At the same time, the equipment and bracket have been installed and it is difficult to disassemble. Therefore, the thread needs to be repaired and reinstalled. However, because the handle of the traditional die device is too long, it interferes with the equipment bracket. This interference may not only cause difficulty in operation, but also cause unnecessary damage to the equipment bracket, such as Figure 1 As shown. Although shortening the handle length of the die device can effectively solve the problem of interference with the equipment bracket, it may bring some other negative effects, which mainly include the following aspects: the shortening of the handle may reduce the overall length of the device, thereby affecting its structural strength and stability. A handle that is too short may not provide sufficient support and torque, causing the device to shake or deform easily during maintenance, reducing the accuracy and efficiency of the operation. Secondly, the length of the handle determines the operator's operating range to a certain extent. If the handle length is too short, the operator may not be able to effectively use the die device at certain angles or positions, thereby limiting its scope of application and flexibility. At the same time, in certain specific cases, a longer handle may help the operator better control the device, especially when a larger torque needs to be applied or more precise operations are required. Shortening the handle length may make these operations more difficult, increasing the difficulty and time cost of maintenance. Existing equipment brackets and fixtures may be designed based on the size of traditional die devices. After shortening the handle length, the newly designed die device may be incompatible with the existing equipment brackets and fixtures, requiring additional adaptation or modification work.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, ordinary technicians in this field can also obtain other embodiments without making creative work.

[0028] See also Figures 2 to 4 The embodiment of the utility model proposes a power-driven die device for thread forming and rapid repair, which is driven by an electric wrench, eliminates the overly long handle of the traditional die device, and is more convenient and flexible to use. Specifically, it includes a fixed bracket 1, on which a threaded sleeve is provided, in which a briquetting screw 4 is installed, and a tap briquetting 3 is provided at the head of the briquetting screw 4, and the tail of the briquetting screw 4 is connected to an electric wrench. The head of the tap briquetting 3 is provided with a tap die 8, and a cavity is machined inside the tap briquetting 3 behind the tap die 8, and the cavity is used to accommodate the screw that has been threaded or repaired, and provides space for the briquetting screw 4 to feed. Preferably, the length of the cavity machined inside the tap briquetting 3 in the embodiment of the utility model is greater than the length of the thread section of the screw to be machined.

[0029] In a possible implementation, horizontal slide grooves are provided on both sides of the fixed bracket 1, a movable slider 2 is installed in the horizontal slide groove, and a clamping plate is provided on the outer side of the movable slider 2. The position of the fixed bracket 1 can be adjusted by the movable sliders 2 on both sides, so that the tap and die 8 and the screw to be processed are in the same axial position and fixed in position.
