All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 2 is a first schematic structural diagram of a shaping assembly according to an embodiment of the present invention; FIG. 3 is a perspective schematic view of the fairing assembly of FIG. 2; fig. 4 is a schematic structural diagram of a shaping assembly according to an embodiment of the present invention; FIG. 5 is a schematic structural diagram illustrating a core being shaped by the shaping assembly according to an embodiment of the present invention; fig. 6 is a perspective view of the core being reshaped by the reshaping component of fig. 5.
Referring to fig. 2 to 6, the present embodiment provides a shaping assembly 200 applied to a winding core, the shaping assembly 200 includes a shaping body 210 and a hot-hole needle 220, the shaping body 210 has a shaping surface 211, a first end of the hot-hole needle 220 is connected to the shaping surface 211, and a second end of the hot-hole needle 220 extends away from the shaping body 210.
Illustratively, the extending direction of the ironing hole needle 220 is perpendicular to the shaping surface 211, and it is understood that the included angle between the extending direction of the ironing hole needle 220 and the shaping surface 211 may be exactly 90 degrees, or the included angle between the ironing hole needle 220 and the shaping surface 211 has a processing error compared with 90 degrees.
The material of the shaping body 210 and the hot hole needle 220 may be beryllium bronze, or the material of the shaping body 210 and the hot hole needle 220 may be other materials known to those skilled in the art to meet the requirements of the present embodiment. The shaping body 210 and the ironing pin 220 may be integrally formed as a single piece, or the shaping body 210 and the ironing pin 220 may be separately manufactured and then assembled or welded together. When the shaping body 210 and the ironing hole needle 220 are respectively installed or welded together after being processed, the shaping body 210 and the ironing hole needle 220 may be made of the same material or different materials.
In particular, the shaping surface 211 is used to abut against the end surface 130 of the core 100 to be shaped so as to shape the end surface 130 of the core 100. Exemplarily, there can be an error of ± 0.01mm by controlling the parallelism between the shaping surface 211 and the end surface 130 of the winding core, so that it can be ensured that the two end surfaces 130 of the winding core shaped by the shaping surface 211 are kept parallel, and further it can be ensured that the overall shape of the winding core meets the design requirements.
The ironing hole needle 220 is used for extending into the central hole 120 of the winding core 100 to be reshaped, and the ironing hole needle 220 can position the winding core 100 on one hand so as to avoid the deviation of the winding core 100 relative to the reshaping surface 211 in the reshaping process, thereby being beneficial to ensuring the reshaping effect of the reshaping component 200 on the end surface 130 of the winding core 100; the ironing pin 220 can support and expand the central hole 120 of the winding core 100 to avoid the dislocation and deformation of the structure of the winding core 100 close to the central hole 120 and occupy the space of the central hole 120, so that the space and the shape of the central hole 120 can be ensured.
In some embodiments, during the process of installing the winding core 100 into the shell, the welding head needs to weld the tab 110 at one end of the winding core 100 to the bottom wall of the shell through the central hole 120, so that the shaping assembly 200 of the present embodiment uses the ironing pin 220 to maintain the shape of the central hole 120 of the winding core, so that the space of the central hole 120 of the winding core is not occupied, and the shaping assembly plays an important role in the structure of the winding core 100 and the subsequent shell entering operation of the winding core 100.
The shaping assembly 200 of the embodiment enables the operation of shaping the end face 130 of the winding core and the operation of reaming the central hole 120 of the winding core to be performed simultaneously, which is beneficial to saving the processing time of the winding core 100 and improving the processing efficiency of the winding core 100; on the other hand, the hot hole needle 220 does not need to be additionally arranged, so that the structure of production equipment is simplified, and the space is saved.
Referring to fig. 2 and 3, optionally, the cross section of the ironing hole needle 220 is circular, and the diameter of the cross section of the ironing hole needle 220 is smaller than the diameter of the central hole 120 of the winding core to be reshaped.
Typically, the central core 120 of the jellyroll is circular in cross-section. The cross section of the ironing hole needle 220 is set to be circular, so that the shape of the ironing hole needle 220 is matched with the shape of the central hole 120 of the winding core, the ironing hole needle 220 can better support and expand the central hole 120 of the winding core, the central hole 120 of the winding core keeps certain roundness, and the lug 110 at one end of the winding core 100 is welded with the bottom wall of the shell through the central hole 120. Illustratively, the shape of the hot-punching pin 220 may be a cylinder, a truncated cone, or other shapes that can meet the requirements of the present embodiment.
With continued reference to fig. 2 and 3, optionally, a cross-sectional diameter of a first end of the ironing hole needle 220 is larger than a cross-sectional diameter of a second end of the ironing hole needle 220, that is, a diameter of an end of the ironing hole needle 220 connected to the shaping surface 211 is larger than a diameter of an end of the ironing hole needle 220 away from the shaping surface 211. Also, the cross-sectional diameter of the ironing hole needle 220 is gradually reduced from the first end of the ironing hole needle 220 to the second end of the ironing hole needle 220.
Illustratively, the shape of the ironing hole needle 220 may be a cone shape or a shape close to a cone shape. Therefore, in the process that the shaping assembly 200 is close to the winding core 100, the ironing hole needle 220 can easily extend into the central hole 120 of the winding core, and meanwhile, along with the extension of the ironing hole needle 220, the central hole 120 of the winding core can be gradually supported and reamed, so that the central hole 120 of the winding core cannot be occupied by extrusion in the shaping process of the end face 130 of the winding core.
In other possible implementations, the shape of the hot hole pin 220 may be composed of two parts from the first end of the hot hole pin 220 to the second end of the hot hole pin 220, for example: the transition from a cylinder to a circular truncated cone, the transition from a cylinder to a cone, or the transition from a circular truncated cone to a cone, etc. Alternatively, the shape of the hot hole forming needle 220 may be composed of three parts from the first end of the hot hole forming needle 220 to the second end of the hot hole forming needle 220, for example, a cylindrical shape is transited to a circular truncated cone and then to a conical shape. Of course, the shape of the perforation needle 220 can be set according to actual needs, and will not be described herein.
Typically, the diameter of the central hole 120 of the reeling core 100 ranges from 1.0mm to 2.5mm, and in order to make the diameter of the largest cross section of the ironing pin 220 smaller than the diameter of the central hole 120 of the reeling core, the diameter of the largest cross section of the ironing pin 220 may be set to range from 0.9mm to 2.4 mm. For example, when the diameter of the central hole 120 of the winding core is 1.0mm, the diameter of the maximum cross section of the ironing needle 220 may be set to 0.9mm, or, when the diameter of the central hole 120 of the winding core is 2.5mm, the diameter of the maximum cross section of the ironing needle 220 may be set to 2.4mm, so that the ironing needle 220 can smoothly extend into the central hole 120 of the winding core.
It can be understood that, when the perforation needle 220 is cylindrical, the diameter of the largest cross section of the perforation needle 220 is the diameter of the cylindrical perforation needle, and thus, the diameter of the cylindrical perforation needle ranges from 0.9mm to 2.4 mm. For example, the diameter of the cylindrical hole ironing needle can be set to 0.9mm, 1.2mm, 1.5mm, 1.8mm, 2.1mm, 2.4mm, etc. according to actual needs.
When the cross-sectional diameter of the first end of the hot hole needle 220 is greater than the cross-sectional diameter of the second end of the hot hole needle 220, and the cross-sectional diameter of the hot hole needle 220 gradually decreases from the first end of the hot hole needle 220 to the second end of the hot hole needle 220, the diameter of the largest cross-sectional area of the hot hole needle 220 is the diameter of the cross-sectional area of the end of the hot hole needle 220 connected with the shaping surface 211. Illustratively, the diameter of the largest cross section of the hot hole needle 220 can be set to 0.9mm, 1.2mm, 1.5mm, 1.8mm, 2.1mm, 2.4mm, etc. according to actual needs.
Referring to fig. 2 to 6, in a possible implementation manner, the shaping surface 211 is circular, and the diameter of the shaping surface 211 is larger than the outer diameter of the core to be shaped, so that the shaping surface 211 can completely cover the end surface 130 of the core to be shaped, and the effect of shaping the end surface 130 of the core to be shaped by the shaping surface 211 can be ensured.
Typically, the outer diameter of the winding core 100 is in the range of 8.0mm to 12mm, and in order to make the shaping surface 211 larger in diameter than the outer diameter of the winding core 100, the shaping surface 211 may be provided in the range of 8.5mm to 12.5mm in diameter. For example, the shaping surface 211 may be provided with a diameter of 8.5mm when the outer diameter of the core 100 is 8.0mm, or the shaping surface 211 may be provided with a diameter in the range of 12.5mm when the outer diameter of the core 100 is 12mm, so that the shaping surface 211 may completely cover the end surface 130 of the core.
Illustratively, the diameter of the shaping surface 211 may be set to 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, etc. according to actual needs.
In other possible implementation manners, the shaping surface 211 may also be set to be a quadrangle, a pentagon, a hexagon or other shapes according to actual needs, as long as it is ensured that the area of the shaping surface 211 is greater than the area of the end surface 130 of the winding core, and the shaping surface 211 can completely cover the end surface 130 of the winding core, so as to realize the purpose of shaping the end surface 130 of the winding core, which is not described again here.
With continued reference to fig. 2 to 6, optionally, the shaping body 210 is provided with a tab hole 212 penetrating through the shaping surface 211, and the tab hole 212 is used for receiving the tab 110 of the winding core to be shaped.
