Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring processing, in particular to a sealing ring processing tool. Background Art

[0002] During the installation and transformation of underground cables, due to the usually harsh underground environment with adverse factors such as humidity, high temperature, and high pressure, these factors may damage the cable system. Therefore, during the installation and transformation of underground cables, more attention needs to be paid to the production of cable terminal heads and the processing of sealing rings to ensure the stability and safety of the cable system.

[0003] In the prior art, when manually processing a sealing ring, since some sealing rings are provided with a pre-treated multi-layer structure, an ordinary screwdriver is usually used to select an appropriate inner diameter and then break off the excess rubber ring. Subsequently, an electrician's knife or a utility knife is used to cut and trim the excess rubber. After cutting and trimming, the electrician master switches to a file to polish the position after the second cutting to improve the sealing effect of the sealing ring.

[0004] For the above-mentioned processing method of the sealing ring, when using an ordinary screwdriver to break it off, it is easy to damage the rubber sealing ring that does not need to be cut. At the same time, when using a utility knife or an electrician's knife for shaping, if the inner diameter of the rubber ring is small, an electrician's knife with a width of about 2 cm is not easy to reach into the sealing ring, and the utility knife is relatively thin and prone to breakage during cutting. Moreover, three tools are required for processing the sealing ring, which requires high electrician skills, low work efficiency, low yield, resulting in damage and waste, and at the same time, it is easy to have misoperations and cut fingers, posing a great safety hazard. Summary of the Utility Model

[0005] The utility model aims at the problems in the prior art and provides an efficient sealing ring processing tool, which solves the problems that three tools are required for manually processing the sealing ring in the prior art, high electrician skills are required, and the work efficiency is low.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A sealing ring processing tool includes a rod body and a handle connected to one end of the rod body. A cutting knife is provided at the other end of the rod body. The cross-section of the cutting knife is C-shaped, and a polishing part is provided on the rod body. By providing a C-shaped cutting knife, it can directly cut according to the required inner diameter size without using an ordinary screwdriver to break off the excess rubber ring. At the same time, the C-shaped cutting knife can directly penetrate the sealing ring without using an electrician's knife or a utility knife to cut the sealing ring. The polishing part provided on the rod body can polish after cutting. During the whole sealing ring processing process, there is no need to change tools, saving time and manual operation, with high work efficiency, and having little impact on the other sealing gaskets that do not need to be cut during the operation, improving the yield.

[0008] Preferably, the cutting knife is detachably arranged on the rod body. By setting the detachable cutting knife, for cutting with different inner diameter requirements, the effect of reducing the cutting times can be achieved by pre-replacing cutting knives of different sizes in advance, thereby reducing the time consumed by cutting and improving the efficiency of sealing ring processing.

[0009] Preferably, a calibration part is arranged between the rod body and the handle. The calibration part is hemispherical, and a plurality of circular calibration grooves are arranged on the spherical surface of the calibration part. The diameter difference between adjacent two calibration grooves is the same. By setting the calibration part and the calibration grooves on the calibration part, after each cutting and grinding, the ground sealing ring can be abutted against the calibration part and calibrated with the calibration grooves of the corresponding diameter, which is convenient for personnel to calibrate the sealing ring.

[0010] Preferably, the cross-section of the rod body is circular. By setting the rod body with a circular cross-section, the grinding part on the rod body is arc-shaped, which is convenient for grinding an arc-shaped inner diameter and avoiding the problem that the sealing effect of the sealing ring is reduced due to excessive grinding of some positions of the sealing ring by the special-shaped grinding part.

[0011] Preferably, at least two grinding parts with different roughnesses are arranged on the rod body. By setting a plurality of grinding parts, during grinding, it can be transitioned from the grinding part with high roughness to the grinding part with low roughness, and one tool can complete the rough grinding for rapid shaping in the early stage and the precise fine grinding in the later stage.

[0012] Preferably, several grinding parts on the rod body are evenly distributed in the circumferential direction. By arranging different grinding parts in the circumferential direction of the rod body, when switching different roughnesses, only need to hold the handle and rotate the rod body to complete the switching, avoiding the problem that the grinding accuracy is not easy to control due to the too large manual pulling amplitude caused by arranging different grinding parts in the length direction of the rod body.

[0013] Preferably, the length of each grinding part is the same as the length of the rod body. When the length of the set grinding part is the same as the length of the rod body, even if the manual pulling is too large, the sealing ring can always be in contact with the grinding part.

[0014] As can be seen from the above technical solutions, the advantages of the present utility model are as follows: By providing a C-shaped cutting knife, it can directly cut according to the required inner diameter size, without using a screwdriver to break off the redundant rubber ring. At the same time, the C-shaped cutting knife can directly penetrate the sealing ring, without the need for an electrician's knife or a wallpaper knife to cut the sealing ring. The grinding part provided on the rod body can perform grinding after cutting. During the entire sealing ring processing process, there is no need to change tools, saving time and manual operation, with high work efficiency, and having little impact on the remaining gaskets that do not need to be cut during the operation process, improving the yield rate. By providing a detachable cutting knife, for cutting with different inner diameter requirements, the effect of reducing the cutting times can be achieved by pre-replacing cutting knives of different sizes, thereby reducing the time consumed by cutting and improving the efficiency of sealing ring processing. By providing a calibration part and calibration grooves on the calibration part, after each cutting and grinding, the ground sealing ring can be abutted against the calibration part and calibrated and compared with the calibration grooves of the corresponding diameter, facilitating the calibration of the sealing ring by personnel. By providing a rod body with a circular cross-section and the grinding part on the rod body being arc-shaped, it is convenient to grind an arc-shaped inner diameter, avoiding the problem that the sealing effect of the sealing ring is reduced due to excessive grinding of some positions of the sealing ring by a special-shaped grinding part. By providing multiple grinding parts, during grinding, it can transition from a grinding part with a high roughness to a grinding part with a low roughness, and a single tool can complete the rough grinding of the rapid shaping in the early stage and the precise fine grinding in the later stage. By providing different grinding parts in the circumferential direction of the rod body, when switching to different roughnesses, only by holding the handle and rotating the rod body can the switching be completed, avoiding the problem that it is not easy to control the grinding accuracy due to too large a manual pulling amplitude when different grinding parts are provided in the length direction of the rod body. When the length of the provided grinding part is the same as the length of the rod body, even if the manual pulling is too large, the sealing ring can always be in contact with the grinding part.
