Description

Technical Field

[0001] The utility model relates to the technical field of inductor winding production devices, in particular to a stripping knife device for inductor winding production. Background Art

[0002] In the inductor production process, the paint stripping and tinning step after winding is a critical step, directly affecting the quality and performance of the product. Traditional wire stripping mechanisms typically use a mechanical drive to open and close the stripping blade, which has many limitations.

[0003] First, common wire stripping systems often incorporate a cylinder in the blade handle, which retracts and retracts to drive the wire clamping and opening of the stripping blade. While this design achieves basic functionality, it is structurally cumbersome and complex. The numerous mechanical components not only increase the size and weight of the equipment, but also raise production and maintenance costs.

[0004] Secondly, pneumatic cylinders are inherently slow. The speed of a cylinder is affected by various factors, including air pressure and piston mass, making it difficult to achieve fast and precise control. This slow speed directly impacts production efficiency and cannot meet the demands of modern large-scale production.

[0005] Furthermore, traditional wire stripping mechanisms face challenges in achieving uniform stripping. Due to mechanical limitations, the pressure and angle of the stripping blades are difficult to precisely control, which can easily lead to inconsistent stripping depth and damage to the wire. This not only affects the product's appearance but can also compromise the inductor's electrical performance.

[0006] In addition, existing wire stripping structures generally lack flexibility and adaptability. When dealing with wires of different specifications and materials, it is often necessary to replace the stripping blade or adjust the equipment parameters, which increases production preparation time and reduces the flexibility of the production line.

[0007] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and the present invention is made based on this situation. Utility Model Content

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] like Figures 1 to 4 The stripping device for inductor winding production shown includes a main blade bar 1 and a plurality of blade handles 2 arranged around the main blade bar 1. The main blade bar 1 is usually connected to the rotating shaft of the motor, and the rotating shaft drives the main blade bar 1 to rotate.

[0033] The middle portion of the handle 2 is pivotally connected to the upper portion of the main blade bar 1, and its center of gravity is located below (i.e., below the pivoting connection point). This design allows the handle 2 to swing under centrifugal force when the main blade bar 1 rotates rapidly. Because the center of gravity of the handle 2 is located downward, the lower portion of the handle 2 swings outward around its center, causing the upper end of the handle 2 to swing inward. When the upper ends of multiple handles 2 swing inward simultaneously, they effectively clamp the winding wire, completing the wire stripping operation.

[0034] The upper end of the handle 2 is provided with a blade 3. The blade 3 is preferably a standard triangular blade with a cutting edge. When the upper ends of multiple handles 2 are simultaneously swung inward, the blades of each blade 3 cooperate to clamp the winding wire. At this point, as the main blade rod 1 rotates, the blade 3 rotates accordingly, peeling the paint film off the winding wire for efficient stripping.

[0035] The lower portion of the main blade bar 1 is rotatably connected to a limit chuck 4. A guide structure is provided between the lower end of the blade handle 2 and the limit chuck 4. This structure guides the lower end of each blade handle 2 to achieve synchronized inward and outward swinging. This guide structure ensures consistent and stable operation of the blade handle 2 during operation, thus preventing poor wire stripping results caused by uncoordinated swinging.

[0036] The primary innovation of this utility model lies in the installation of a torsion spring 5 between the limit chuck 4 and the main blade rod 1. Typically, the torsion spring 5 is tightened in the same direction as the main blade rod 1 rotates. As the main blade rod 1 rotates, the torsion spring 5 is compressed, storing energy. When the main blade rod 1 stops rotating, the torsion spring 5 releases its elastic force, rapidly accelerating the stop of the limit chuck 4 and guiding the lower ends of each blade handle 2 to retract synchronously. This mechanism allows the upper ends of each blade handle 2 to open synchronously and quickly reset, ensuring the prompt start of the next wire stripping operation.

[0037] Furthermore, the specific installation position of the torsion spring 5 is as follows: the lower end of the main tool rod 1 is fixedly connected to a fixed sleeve 11, the torsion spring 5 is sleeved on the main tool rod 1, one end of the torsion spring 5 is connected to the fixed sleeve 11, and the other end of the torsion spring 5 is connected to the limit chuck 4.

[0038] Furthermore, the specific structure of the guide structure is as follows: the guide structure includes a first pin 6 provided at the lower end of the tool handle 2, and a plurality of guide holes 41 provided on the limiting chuck 4 for receiving corresponding first pins 6. The guide holes 41 are all strip-shaped or arc-shaped holes that gradually extend inward along the tightening direction of the torsion spring 5. When the torsion spring 5 rotates in the tightening direction relative to the main tool bar 1, the first pin 6 moves outward along the corresponding guide hole 41; when the torsion spring 5 rotates in the relaxing direction relative to the main tool bar 1, the first pin 6 moves inward along the corresponding guide hole 41.

[0039] More specifically, a bearing 7 is provided between the limiting chuck 4 and the main tool rod 1 , and the bearing 7 can reduce the friction between the limiting chuck 4 and the main tool rod 1 and increase the smoothness of rotation.

[0040] More specifically, the upper end of the handle 2 is provided with a mounting slot 21, into which the blade pellet 3 is removably mounted using fasteners (such as screws). This structure facilitates the removal and replacement of the blade pellet 3. When the blade pellet is worn or damaged, the entire handle need not be replaced; only the blade pellet can be replaced, significantly extending the device's service life and economic efficiency. Furthermore, the mounting slot 21 is highly versatile and can accommodate standard triangular blade pellets commonly found on the market.

[0041] Furthermore, the handle 2 is manufactured using an integrated molding process. This process not only simplifies the handle production process and improves processing efficiency, but also provides high structural strength because the handle structure lacks weak points caused by splicing or welding. During actual use, the handle 2 can withstand high operating pressures and stresses without damage, ensuring the stability and reliability of the peeling device as a whole. Furthermore, the integrated molded handle features an attractive appearance and a comfortable feel, meeting the requirements of modern industrial design.

[0042] More specifically, a second pin 8 is provided between the middle portion of the tool handle 2 and the side surface of the main tool rod 1 for rotatably connecting the two.

[0043] More specifically, the lower portion of the main shank 1 is fixedly connected to a limit ring 9, the inner side of which is provided with a plurality of guide grooves 91 for the corresponding shank 2 to swing in and out. The guide grooves 91 act as a limiter to prevent the lower portion of the shank 2 from swinging outward excessively.

[0044] More specifically, the outer side of the limiting ring 9 is provided with a plurality of adjustment holes 92 leading to the corresponding guide grooves 91, and the adjustment holes 92 are threadedly connected with adjustment parts (not shown in the figure, preferably screws) that can adjust the length of the adjustment parts inserted into the guide grooves 91 and thus adjust the swing amplitude of the shank 2.

[0045] More specifically, a central cavity 12 for passing the wire is provided at the center of the main tool bar 1 .
