Description

Technical Field

[0001] This utility model relates to the field of precision wire processing technology, and in particular to a novel cutting blade. Background Technology

[0002] In the field of inductor manufacturing, the precision cutting of flat wires (such as rectangular copper wires) is a key process affecting coil performance. However, existing cutting technologies have the following prominent problems:

[0003] The springback problem is particularly prominent in flat wire cutting. Due to the large width-to-thickness ratio of flat wire (usually ≥5:1), in traditional cutting processes, when the shearing force is suddenly unloaded, the rear section of the wire at the cut position will exhibit significant springback deformation under the straightening tension. This springback manifests in two main ways: first, the cut end face experiences a displacement springback of 0.1-0.3mm, making it difficult to control the coil turn spacing in subsequent winding processes; second, the narrow side of the wire exhibits a warping deformation of 0.05-0.15mm, affecting the quality of the inductor coil.

[0004] Furthermore, the problem of poor consistency in dual-station cutting also urgently needs to be addressed. To improve production efficiency, modern inductor production lines generally adopt dual-station cutting equipment, but the traditional dual-cylinder drive system has obvious technical defects: First, the cumulative error of the mechanical transmission chain leads to asynchronous cutting actions between the two stations; second, due to the lack of an effective load balancing mechanism, when there is a difference in wire hardness between the two stations, one side will be incompletely cut while the other side is overcut, resulting in significant differences in cross-sectional quality.

[0005] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a new type of cutting blade to solve the above problems.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0007] To overcome the shortcomings of the prior art, the present invention discloses a novel cutting blade to solve the problems of wire springback deformation and poor consistency in multi-station cutting during the manufacturing process of inductor coils.

[0008] This utility model discloses a novel cutting knife, comprising:

[0009] The mounting base is symmetrically equipped with telescopic adjustment components on both sides, allowing the mounting base to be adjusted in front and behind while keeping the two sides level.

[0010] The collinear drive module consists of a first linear driver and a second linear driver arranged coaxially. The collinear drive module is fixed to the operating side of the mounting base to realize synchronous collinear movement of the two drivers.

[0011] An interactive actuator includes: a first U-shaped linkage assembly, the drive end of which is rigidly connected to the output shaft of a first linear actuator. The vertical arm of the U-shaped frame of this assembly is provided with a guide groove. This assembly includes a first pressing unit and a first shearing unit parallel to it, symmetrically distributed on the left and right sides; a third pressing unit and a third shearing unit parallel to it; and a second U-shaped linkage assembly, the drive end of which is rigidly connected to the output shaft of a second linear actuator. The top of the U-shaped frame of this assembly slides in conjunction with the guide groove. This assembly includes a second pressing unit coaxially arranged with the first pressing unit; a second shearing unit forming an interlaced shearing surface with the first shearing unit; a fourth pressing unit coaxially arranged with the third pressing unit; and a fourth shearing unit forming an interlaced shearing surface with the third shearing unit. The first and second U-shaped linkage assemblies are dynamically coupled through a horizontal slide rail pair. The two sets of U-shaped assemblies move with a phase difference under collinear drive, achieving seamless connection of the "clamping-shearing-release" actions between the two workstations.

[0012] Preferred technical solution: In the first shearing pair composed of the first shearing unit and the second shearing unit, the offset of the cutting edge line is 0.1-0.5 times the width of the narrow face of the wire. The second shearing pair composed of the third shearing unit and the fourth shearing unit has the same offset, which ensures a smooth cut while reducing burr generation.

[0013] Preferred technical solution: The contact end faces of the first pressing unit and the second pressing unit, as well as the third pressing unit and the fourth pressing unit, are all provided with elastic buffer structures to avoid squeezing damage to the wire.

[0014] Preferred technical solution: The blades of the first shearing unit, the second shearing unit, the third shearing unit, and the fourth shearing unit all adopt an indexable blade structure, and quick-change installation is achieved through T-slots and positioning pins. The first pressure rod, the second pressure rod, the third pressure rod, and the fourth pressure rod all adopt a plug-in quick-change installation structure, which facilitates maintenance and replacement.

[0015] Preferred technical solution: The telescopic adjustment component integrates a laser displacement sensor, which forms a closed-loop control system with the collinear drive module to ensure cutting accuracy.

[0016] Preferred technical solution: The telescopic adjustment assembly, the first linear actuator, and the second linear actuator are one of an electric cylinder, a hydraulic cylinder, and a pneumatic cylinder.

[0017] This utility model discloses a cutting method using a novel cutting knife, comprising the following steps:

[0018] S1. Set the initial cutting position using the telescopic adjustment component;

[0019] S2. The first linear actuator and the second linear actuator synchronously advance the first U-shaped linkage assembly and the second U-shaped linkage assembly to contact the wires on the two workstations respectively;

[0020] S3. The first linear driver and the second linear driver continue to advance, so that the first shearing unit and the second shearing unit, as well as the third shearing unit and the fourth shearing unit, respectively perform staggered cutting of the wires at the two workstations. At the same time, the first pressing unit and the second pressing unit, as well as the third pressing unit and the fourth pressing unit, respectively clamp the rear end of the wires at the cutting position at the two workstations to prevent the wires from springing back.

[0021] S4. The first and second linear drives retract, and the interactive actuator releases the wire, completing one cutting cycle.

[0022] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0023] 1) The pressing unit clamps the wire before shearing to prevent springback caused by tension release. At the same time, the staggered shearing surfaces make the wire cut surface smoother and reduce the amount of end deformation.

[0024] 2) The interactive actuator ensures that the cutting actions of the two stations are completely consistent, eliminating cumulative mechanical errors.

[0025] 3) An elastic buffer structure is set at the joint of the pressing unit to avoid squeezing and deforming the wire. Attached Figure Description

[0038] like Figure 1 and Figure 2 As shown, telescopic adjustment components 2 are symmetrically arranged on both sides of the mounting base 1. The position is monitored in real time by a laser displacement sensor to ensure cutting accuracy. The collinear drive module consists of a first linear driver 3 and a second linear driver 4 arranged coaxially. Both are servo electric cylinders and achieve synchronous movement through a closed-loop control system.

[0039] like Figure 1 and Figure 2As shown, the interactive actuator consists of a first U-shaped linkage component 5 and a second U-shaped linkage component 6. The drive end of the first U-shaped linkage component 5 is rigidly connected to the output shaft of the first linear actuator 3, and a guide groove 55 is provided on the vertical arm of its U-shaped frame.

The drive end of the second U-shaped linkage component 6 is rigidly connected to the output shaft of the second linear actuator 4, and the top of its U-shaped frame slides in cooperation with the guide groove 55. The second U-shaped linkage component 6 includes a second pressing unit 61, a second shearing unit 62, a fourth pressing unit 63, and a fourth shearing unit 64. The two sets of U-shaped components are dynamically coupled through a horizontal slide rail pair 7 to ensure synchronized action. In the first shearing pair formed by the first shearing unit 52 and the second shearing unit 62, the working surfaces of the two shearing units are arranged in parallel and staggered, and the offset of their cutting edge lines is 0.2 times the width of the narrow face of the wire. The second shearing pair formed by the third shearing unit 54 and the fourth shearing unit 64 has the same offset. The contact surfaces of the first pressing unit 51 and the second pressing unit 61, as well as the third pressing unit 53 and the fourth pressing unit 63, are all provided with elastic buffer structures 8.

[0042] Clamping stage: The first linear driver 3 and the second linear driver 4 advance synchronously, so that the first pressing unit 51 and the second pressing unit 61, as well as the third pressing unit 53 and the fourth pressing unit 63, respectively clamp the rear end of the wire at the two work stations, and the elastic buffer structure 8 avoids squeezing damage.

[0043] Shearing stage: The first linear actuator 3 and the second linear actuator 4 continue to advance, and the first shearing unit 52, the second shearing unit 62, the third shearing unit 54 and the fourth shearing unit 64 respectively use staggered cutting edges to complete the shearing of the corresponding wires, with smooth cuts without burrs.

[0044] Release phase: The first linear driver 3 and the second linear driver 4 retract, the pressing unit releases the wire, and one cutting cycle is completed.

[0045] like Figure 1 and Figure 2As shown, the blades of the first shearing unit 52, the second shearing unit 62, the third shearing unit 54, and the fourth shearing unit 64 all adopt an indexable blade structure, and quick-change installation is achieved through T-slots and positioning pins.
