Description

Technical Field

[0001] The invention relates to the field of cutting tool equipment, and in particular to a cutting tool for a terminal crimping machine capable of automatically removing chips. Background Art

[0002] The quality, life and reliability of the tool are one of the key indicators that reflect the quality level of the entire equipment. They are an indispensable part of any equipment. Therefore, the design optimization of the tool has become the focus of attention of various equipment manufacturers and users. One side of the tool fits tightly with the other parts of the crimping machine, and the crimping material is placed on the inside of the tool. When ordinary tools cut the crimping material, the metal fragments generated are easily squeezed into the fitting surface of the tool and the parts. When these chips accumulate to a certain extent, a gap is generated between the cutter and other parts. When the gap reaches a certain level, it will cause burrs on the product, tool breakage and other problems. Ensuring good quality, long life and high reliability during the use of the tool is an inevitable requirement for the technological development of the equipment manufacturing industry. Therefore, by optimizing the tool design, the purpose of improving the quality level of the entire equipment and reducing the cost of tool use can be achieved. Summary of the invention

[0003] The purpose of the present invention is to provide a terminal crimping machine cutting tool that can realize automatic chip removal in order to solve the problems existing in the prior art. The chips entering the installation gap are discharged through the chip removal groove, thereby avoiding the problems of burrs on the product and tool damage.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] The terminal crimping machine cutting tool capable of realizing automatic chip removal comprises a tool body, the tool body is a rectangular thin plate structure, the tool body comprises a mounting end face for fitting with a fixed component, and a bottom end face opposite to the mounting end face, the mounting end face is provided with two penetrating mounting through holes, the tool body comprises a left side edge and a right side edge opposite to each other, the left side edge of the tool body is provided with a V-shaped cutting opening, the V-shaped cutting opening penetrates the two end faces of the tool body, the mounting end face is provided with a cutting opening extending toward the bottom end face Chip groove, one side of the chip groove extends to the right side edge of the tool body, the upper groove edge of the chip groove is located above the corner of the V-shaped cutting opening, the lower groove edge of the chip groove is inclined downward, the groove bottom surface of the chip groove is an inclined slope, the depth of the chip groove gradually increases from left to right, the distance between the right end of the groove bottom surface of the chip groove and the mounting end face is 0.2-0.4 mm, the thickness of the tool body is 1.65 mm, and the ratio of the area of ​​the chip groove to the mounting end face does not exceed 15%.

[0006] In the above scheme, the tool body is fixed by the combination of the mounting end face and the fixed component, and the crimped material is cut off by the V-shaped cutting opening. During the cutting process, due to the manufacturing tolerance of the tool body, there is a mounting gap between the mounting end face and the fixed component, and the cutting debris enters the mounting gap. The chip removal groove is used to discharge the entered debris to avoid burrs on the product and tool damage.

[0007] Wherein, by locating the upper groove edge of the chip removal groove above the corner of the V-shaped cutting opening and tilting the lower groove edge of the chip removal groove downward, the chips can directly enter the chip removal groove, and the chips are prevented from entering the installation gap;

[0008] By setting the bottom surface of the chip removal groove as an inclined slope and making the depth of the chip removal groove gradually increase from left to right, it is convenient for the debris entering the installation gap to slide out automatically and avoid accumulation;

[0009] By extending one side of the chip removal groove to the right side of the tool body, the chips entering the chip removal groove are discharged from the right side of the tool body;

[0010] By making the distance between the right end of the bottom surface of the chip removal groove and the mounting end surface 0.2-0.4 mm and the thickness of the tool body 1.65 mm, it is avoided that the tool body is partially damaged due to being too thin and insufficient in strength;

[0011] By making the ratio of the chip removal groove to the area of ​​the mounting end face not exceed 15%, it is avoided that the tool body is mounted unsteadily and the cutting effect is affected by vibration.

[0012] Furthermore, the corner of the V-shaped cutting opening is located on the center line of the tool body, and the two oblique sides of the V-shaped cutting opening are symmetrically arranged relative to the center line. The V-shaped cutting opening is arranged on the center line of the tool body so that the tool body can be evenly stressed during cutting.

[0013] Furthermore, the distance between the left end of the groove bottom surface of the chip removal groove and the mounting end surface is zero. The debris slides into the chip removal groove from the left end and automatically slides out on the inclined groove bottom surface to avoid accumulation.

[0014] Furthermore, the diameter of the mounting through hole is 5.0-5.5 mm, and the area ratio of the two mounting through holes to the mounting end surface does not exceed 10%. The mounting through hole is used to connect the tool body with the fixed component by bolts or pins.

[0015] Furthermore, the two mounting through holes are symmetrically arranged relative to the center line of the tool body.

[0016] Furthermore, the side connection of the tool body is provided with an anti-fool chamfer, which is used to make the tool body and the fixed component symmetrical in appearance and avoid reverse installation.

[0017] Furthermore, the cross-section of the chip removing groove is a right-angled trapezoid, and the left groove side of the chip removing groove is perpendicular to the center line of the tool body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The tool body is fixed by the mounting end face and the fixed parts, and the crimping material is cut through the V-shaped cutting opening. During the cutting process, the debris of the cutting material enters the installation gap, and the chip removal groove is used to discharge the incoming debris to avoid burrs on the product and tool damage;

[0020] 2. By locating the upper groove edge of the chip removal groove above the corner of the V-shaped cutting opening and tilting the lower groove edge of the chip removal groove downward, the chips can directly enter the chip removal groove, and the chips are prevented from entering the installation gap;

[0021] 3. By setting the bottom surface of the chip removal groove as an inclined slope and making the depth of the chip removal groove gradually increase from left to right, it is convenient for the debris entering the installation gap to slide out automatically and avoid accumulation;

[0022] 4. By extending one side of the chip removal groove to the right side of the tool body, the chips entering the chip removal groove are discharged from the right side of the tool body;

[0023] 5. By setting the distance between the right end of the bottom surface of the chip removal groove and the mounting end surface to 0.2-0.4 mm, the thickness of the tool body is 1.65 mm, so as to avoid the tool body being easily damaged due to being too thin and insufficient in strength;

[0024] 6. By ensuring that the chip removal groove accounts for no more than 15% of the area of ​​the mounting end surface, it is possible to avoid unstable installation of the tool body and affect the cutting effect due to vibration. BRIEF DESCRIPTION OF THE DRAWINGS
