Description

Technical Field

[0001] The invention relates to the technical field of steel wire surface treatment, in particular to a steel wire cutting mechanism. Background Art

[0002] The technical solution for wire cutting mainly consists of a triangular-structured turning tool, a tool holder, a turntable, a belt, a motor and other components (see Figure 1 ), in which the turntable cooperates with the driving mechanism such as the motor, and all the turning tools can gather towards the center to form a radial clamping pressure on the steel wire. During operation, the turning tools rotate at high speed with the turntable, and the steel wire performs axial feed movement, and the tip of the tool is used to perform turning / stripping on the surface of the round steel wire. At present, the above scheme has significant limitations in practical applications: First, the above scheme is only applicable to the processing of thick steel wires with a diameter of ≥15mm. When processing thin steel wires with a diameter of less than 10mm, the tool gap is too small, and the cutting debris cannot be effectively discharged, and then chips are formed in the tool area, causing irreversible scratches on the surface of the steel wire (see Figure 3 ); Second, the triangular turning tool (see Figure 2 ) design only uses the tip of the tool for cutting, which not only limits the effective working area of ​​the tool, resulting in a shortened service life (the tip of the tool is prone to breakage), but also because the contact area between the tip of the tool and the steel wire is small, obvious spiral knife marks will remain on the surface after peeling, and additional grinding equipment is required for secondary polishing to meet the surface finish requirements, which indirectly leads to increased labor costs. Based on the above description, this article specifically proposes a cutting mechanism suitable for steel wires of different thicknesses. Summary of the invention

[0003] The purpose of the present invention is to provide a wire cutting mechanism to solve the above technical problems.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A wire cutting mechanism comprises a main machine and a rotating disk arranged in the main machine. The wire enters and passes out from the rotating disk axis. The rotating disk extends outward from the main machine. The end of the extending part has a plurality of installation positions surrounding its own axis.

[0006] The tool holder is equipped with a turning tool, which contacts or moves away from the steel wire when the tool holder moves radially relative to the turntable. The motor drives the turntable to rotate so that the turning tool in contact with the steel wire cuts the surface of the steel wire.

[0007] The turning tool is an irregular hexagon. In addition, the side of the tool holder facing the steel wire has an oblique angle. When all the tool holders are brought closer together, the oblique angle expands the gap between adjacent tool holders.

[0008] Preferably, the side edge of the turning tool contacts the surface of the wire.

[0009] Preferably, the side of the cutting tool contacting the wire surface must be flat.

[0010] Preferably, it also includes an air blowing member installed on the tool holder, which is divided into a gas producing part and a roller arranged in the gas producing part for contacting the steel wire, wherein the rotating roller is the power source of the gas producing part, and the air inlet and outlet positions of the gas producing part point to the gap between adjacent tool holders.

[0011] Preferably, when the motor drives the turntable to rotate, the roller located in the gas producing part rolls and contacts the steel wire.

[0012] Preferably, the roller contacts the uncut wire in front of the cutting zone.

[0013] Preferably, the gas generating part blows gas into the gap intermittently.

[0014] Preferably, the gas generating part comprises a housing, the housing is provided with a first chamber for mounting the roller, and a second chamber adjacent to the first chamber, a gas cylinder is arranged in the second chamber, the axial position of the roller is a shaft, the shaft enters the second chamber from the first chamber, and the shaft entering the second chamber is provided with a rocking bearing;

[0015] There is a piston in the cylinder, and the piston is equipped with a rod connected to a rocking bearing, which is used to make the piston reciprocate in the cylinder when the shaft rotates.

[0016] The gas producing part also includes a through hole arranged in the gas cylinder, and the through hole discharges air outwards or draws air inwards when the piston reciprocates.

[0017] Preferably, a shaft fixes the roller in the first chamber.

[0018] Preferably, it also includes a pipe connected to the through hole, one of the pipe openings of the pipe is connected to the through hole, and the other pipe opening of the pipe points to the gap between adjacent tool holders.

[0019] The beneficial effects of the present invention are:

[0020] 1. In the present invention, the front end of the tool holder adopts a bevel design, which increases the gap between adjacent tool holders when all tool holders gather toward the center. This innovative design not only ensures the compactness of the tool holder assembly, but also provides a discharge channel for cutting debris compared to conventional structures, effectively solving the traditional problem of chip accumulation.

[0021] 2. The specially designed asymmetric hexagonal structure contains a precision-ground flat cutting edge, which forms a surface contact with the wire surface, greatly improving the service life of the turning tool and eliminating the deep knife marks on the wire surface after stripping.

[0022] 3. The present invention also adds an air blowing member that moves with the turntable. The air blowing member generates airflow by contacting the steel wire, and performs air blowing treatment on the cutting activity to be performed, so that the debris generated during cutting can be efficiently discharged along the preset channel under the dual effects of the inclined surface gap guidance and the compressed airflow.

DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0035] The specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0036] Embodiment 1: In this embodiment, a wire cutting mechanism is proposed. Figure 1-Figure 3 For reference, see Figure 4-Figure 7 The wire cutting mechanism is composed of a main machine 1, a turntable 2, a tool holder 3, and a turning tool 4 as a core cutting system, wherein the turntable 2 is installed inside the main machine 1, and a hole is provided at its axial position for the wire to pass through. The turntable 2 extends outward from the main machine 1, and the end extending outward has four mounting positions surrounding its own axis, wherein each mounting position fixes the tool holder 3 by a second screw 6, wherein the tool holder 3 can move radially relative to the turntable 2, and the front end of the tool holder 3 adopts a bevel design, which can increase the wedge-shaped gap between adjacent tool holders 3 when all tool holders 3 gather toward the center. This innovative design not only ensures the compactness of the tool holder assembly, but also provides a discharge channel for cutting debris compared to conventional structures, effectively solving the traditional problem of chip accumulation. The turning tool 4 is fixed to the front end of the tool holder 3 by a first screw 5. It should be noted that, please refer to Figure 3 and Figure 7 The through hole of the turning tool 4 for the first screw 5 to penetrate is designed to be a cone mouth. The cone mouth design allows the cap of the first screw 5 to enter the turning tool 4, further increasing the space between the tool holders 3. Finally, the specially designed asymmetric hexagonal structure includes a precisely ground flat cutting edge, which forms a surface contact with the surface of the steel wire. When the motor 8 drives the turntable 2 to rotate, the turning tool 4 contacting the steel wire can cut the surface of the steel wire. In this embodiment, a polishing machine 9 is also added behind the cutting mechanism. The polishing machine 9 can polish the peeled steel wire to further improve the quality of the steel wire.

[0037] Embodiment 2: In this embodiment, a wire cutting mechanism is proposed, which is different from Embodiment 1. In this embodiment, an active chip removal structure is added on the basis of Embodiment 1. Figure 1-Figure 3 For reference, see Figure 4-Figure 9The wire cutting mechanism is composed of a main machine 1, a turntable 2, a tool holder 3, a turning tool 4 and an air-blowing component to form a core cutting system. Consistent with some of the contents in the embodiments, the turntable 2 is installed inside the main machine 1, and a hole is provided at its axial position for the wire to pass through. The turntable 2 extends outward from the main machine 1, and the end extending outward has four mounting positions surrounding its own axis, wherein each mounting position fixes the tool holder 3 by a second screw 6, wherein the tool holder 3 can move radially relative to the turntable 2, and the front end of the tool holder 3 adopts a bevel design, which can increase the wedge-shaped gap between adjacent tool holders 3 when all tool holders 3 gather toward the center. This innovative design not only ensures the compactness of the tool holder assembly, but also provides a discharge channel for cutting debris compared to conventional structures, effectively solving the traditional problem of chip accumulation. The turning tool 4 is fixed to the front end of the tool holder 3 by a first screw 5. It should be noted that, please refer to Figure 3 and Figure 7 The through hole of the turning tool 4 for the first screw 5 to penetrate is designed to be a cone, and the cone design allows the cap of the first screw 5 to enter the turning tool 4, further increasing the space between the tool holders 3. Finally, the specially designed asymmetric hexagonal structure includes a precisely ground flat cutting edge, which forms a surface contact with the surface of the steel wire. When the motor 8 drives the turntable 2 to rotate, the turning tool 4 contacting the steel wire can cut the surface of the steel wire.

[0038] In this embodiment, the above-mentioned air blowing part is innovatively integrated on the side of the tool holder 3, and the gas-producing part 10 and the roller 11 form a linkage unit. The gas-producing part 10 includes a shell 101, and the interior of the shell 101 is divided into a first chamber and a second chamber, wherein the roller 11 is fixed in the first chamber by a shaft 103, and its axial extension section penetrates into the second chamber and is equipped with a rocking bearing 104, and the second chamber is provided with an air cylinder 102, and its internal piston 107 is connected to the rocking bearing 104 through a composite connecting rod mechanism composed of a first rod 105 and a second rod 106, the first rod 105 and the rocking bearing 104 are universally hinged, and the second rod 106 is rigidly connected to the piston 107. Based on the above description, when the roller 11 contacts the steel wire, the rotary motion of the shaft 103 can be converted into a linear reciprocating motion of the piston 107 through the rocking bearing 104 by rotating the turntable 2, and the mechanical energy conversion system can generate 6-8 effective strokes per rotation cycle. In this embodiment, the air cylinder 102 is provided with a through hole 108, and the through hole 108 is combined with a pipeline to extend the air inlet or exhaust port of the air cylinder 102 to the gap between adjacent tool holders 3, so that a negative pressure suction environment is formed when the piston 107 is pulled, and a compressed air flow is generated when it is pushed. The intermittent blowing system directionally removes cutting debris. Among them, the specially designed roller 11 is installed in front of the cutting path to ensure that the air blowing action occurs at the moment of cutting and forming, and its contact point is located on the surface of the unprocessed steel wire to avoid interference with the processed area. When the whole machine is running, the spiral chips generated by the synchronous operation of the four sets of tool holders 3 are efficiently discharged along the preset channel under the dual effects of the inclined gap guidance and the compressed air flow, so that the cutting area is always kept clean.

[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
