Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting chamfering tools, and particularly relates to a two-edge alloy chamfering tool. Background Art

[0002] In the process of processing pipe fittings, chamfering treatment is a crucial link. It can not only improve the quality effect of the end face of pipe fittings after cold cutting, but also significantly enhance the stability and reliability of pipe fittings in subsequent process treatments such as welding. Traditional chamfering processing methods mainly achieve this by increasing the sharpness of the chamfering tool and adjusting the feed rate. However, this approach often leads to a significant reduction in the service life of the chamfering tool and is prone to causing over-interference in the chamfering of pipe fittings, thereby resulting in damage.

[0003] In order to overcome these problems, the industry has conducted a large number of explorations and improvements. However, how to improve production efficiency and processing quality on the basis of ensuring the unchanged service life of the chamfering tool remains an urgent technical problem to be solved. Traditional single-edge chamfering tools often struggle to balance efficiency and quality during processing, and increasing the sharpness of the chamfering tool will lead to a decrease in tool life.

[0004] Therefore, the market urgently needs a new type of two-edge alloy chamfering tool that can improve the efficiency and quality of chamfering processing, reduce damage to pipe fittings, and lower production costs while ensuring the service life of the tool. Content of the Utility Model

[0005] In order to solve the above problems, the utility model provides a two-edge alloy chamfering tool. The two-edge alloy chamfering tool has a simple and compact structure, reasonable design, and uses two differently angled cutting edges arranged in a pyramid shape to improve the reuse rate, reduce the usage quantity of the cutting edges and the body, and reduce production costs on the basis of improving production efficiency and equipment utilization rate.

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

[0007] A two-edge alloy chamfering tool is composed of an integral chamfering tool body, a first-layer cutting edge, and a second-layer cutting edge. The first-layer cutting edge and the second-layer cutting edge respectively include two cutting edges arranged in a pyramid shape and symmetric about the center of the chamfering tool body. The included angles of the two cutting edges of the first-layer cutting edge and the second-layer cutting edge are not equal.

[0008] The included angle of the two cutting edges of the first-layer cutting edge is 60°, the included angle of the two cutting edges of the second-layer cutting edge is 90°, the first-layer cutting edge is arranged on the outside, and the second-layer cutting edge is arranged on the inside of the first-layer cutting edge.

[0009] A spiral chip removal groove is arranged between the two cutting edges of the first-layer cutting edge and the second-layer cutting edge.

[0010] The diameter of the chamfering tool body is 6 mm.

[0011] The maximum outer diameter of the first-layer cutting edge is 3 mm.

[0012] The maximum outer diameter of the second-layer cutting edge is 6 mm.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. A two-edge alloy chamfering tool disclosed by the present utility model. By designing a new type of two-edge alloy chamfering tool, the tool has a first-layer cutting edge and a second-layer cutting edge, which are centrosymmetric angles of 60° and 90° respectively. This design enables the tool to first perform a preliminary round-corner chamfering with the smaller 60° cutting edge during the machining process, and then perform a secondary chamfering with the larger 90° cutting edge, thereby improving the production efficiency while ensuring the machining quality.

[0015] 2. A two-edge alloy chamfering tool disclosed by the present utility model. Since the two-edge alloy chamfering tool uses cutting edges with two different angles for step-by-step chamfering, and the large-angle cutting edge can effectively carry out the chips generated during the chamfering process through self-rotation and chip evacuation grooves, it avoids the possible scratching and iron chip residue problems during the chamfering of pipeline components, and reduces the damage to pipeline components.

[0016] 3. A two-edge alloy chamfering tool disclosed by the present utility model. By reasonably designing the structures of the tool handle and the cutting edge, the strength of the tool body is enhanced. At the same time, due to the adoption of the step-by-step chamfering method, the wear of the tool caused by single machining is reduced, enabling the tool to be reused up to 5000 times, significantly improving the reuse rate and service life of the tool.

[0023] The utility model: 1. Chamfering tool body, 2. First layer of cutting edge, 3. Second layer of cutting edge. Detailed implementation method

[0024] As Figure 1 shown, the two-edge alloy chamfering tool mainly consists of a chamfering tool body 1, a first layer of cutting edge 2 and a second layer of cutting edge 3.

[0025] Among them, the chamfering tool body 1 is cylindrical with a diameter of 6 mm, providing sufficient strength and stability. The first layer of cutting edge 2 and the second layer of cutting edge 3 are respectively arranged at the ends of the chamfering tool body 1, and both include two cutting edges arranged in a pyramid shape symmetrically along the center of the chamfering tool body, as Figure 2 and Figure 3 shown.

[0026] The included angle between the two cutting edges of the first layer of cutting edge 2 is 60°, arranged in a pyramid shape. Its maximum outer diameter is 3 mm, ensuring that it can easily enter the pipe during the preliminary rounding of the corner and effectively perform the rounding of the corner. The included angle between the two cutting edges of the second layer of cutting edge 3 is 90°, also arranged in a pyramid shape, and its maximum outer diameter is the same as the diameter of the chamfering tool body 1, which is 6 mm. In this way, when the second layer of cutting edge 3 performs secondary chamfering, it can ensure full contact with the pipe end face and achieve an ideal chamfering effect.

[0027] When using this two-edge alloy chamfering tool for chamfering processing, first insert the 60° cutting edge of the first layer into the pipe, and make it rotate self and rotate around the pipe port. Due to the smaller included angle of 60°, it can easily perform the preliminary rounding of the corner and reduce the damage of the tool to the pipe wall. Subsequently, by adjusting the feed rate, the 90° cutting edge of the second layer starts to contact the pipe end for secondary chamfering. The included angle of 90° can ensure full contact with the pipe end face and achieve an ideal chamfering angle and surface quality.

[0028] At the same time, a spiral chip removal groove is provided between the two layers of cutting edges. During the chamfering process, the generated chips will be carried out through self-rotation and the chip removal groove, avoiding the chips remaining in the pipe or scratching the pipe wall.

[0029] This two-edge alloy chamfering tool can significantly improve the processing efficiency and reduce the processing time by using two kinds of angle cutting edges for step-by-step chamfering.

[0030] The first layer of 60-degree cutting edge performs preliminary rounding of the corner, and the second layer of 90-degree cutting edge performs secondary chamfering, which can ensure the accuracy of the chamfering angle and the smoothness of the surface quality. At the same time, the design of the spiral chip removal groove can avoid chip residue and pipe wall scratching.

[0031] The reasonably designed tool shank and cutting edge structure enhance the strength of the tool body, enabling the tool to be reused up to 5,000 times, significantly improving the reuse rate and service life.

[0032] Due to the extended service life of the tool and the improved processing efficiency, the tool replacement frequency and production costs are reduced. At the same time, due to the improved processing quality, the rejection rate and rework costs caused by pipeline component damage are also reduced.

[0033] In summary, this two-edge alloy chamfering tool has the processing characteristics of high efficiency, high quality and low cost, and is particularly suitable for chamfering processing of pipeline components.
