Description

一种扁铜线弯折成型装置Device for bending and forming flat copper wire 技术领域Technical field
本发明涉及电机生产技术领域，尤其是涉及一种用于电机定子用扁铜线的弯折成型装置。The invention relates to the technical field of motor production, in particular to a bending and forming device for rectangular copper wires for motor stators.
背景技术Background technique
随着汽车行业的蓬勃发展，相应的对于电机的需求也日益增大，而电机性能的优异与否直接决定了汽车的性能。传统的圆铜线电机定子绕组由于其方便的装配性而盛行一时，但是伴随着汽车行业的蓬勃发展对于电机的各方面性能也提出了更高的要求，要求电机的体积更小、功能更强、运行速度更快。With the vigorous development of the automotive industry, the corresponding demand for motors is also increasing, and the performance of the motors directly determines the performance of the car. Traditional round copper wire motor stator windings have prevailed for a while due to their convenient assembly. However, with the booming development of the automotive industry, higher requirements have been placed on all aspects of the motor performance, requiring the motor to be smaller and more powerful. , Run faster.
与传统的圆铜线电机定子绕组相比，扁铜线绕组在相同的体积下，具有重量轻、效率高、高压下噪音小的优点，从技术角度来说，在同等尺寸下，可通过更大电流，适应更高频率，能够获取更高品质因数。但是相比于传统圆铜线绕组来说，扁铜线绕组的装配难度更大，目前在国内市场的应用还不广。Compared with the traditional round copper wire motor stator winding, the rectangular copper wire winding has the advantages of light weight, high efficiency, and low noise under high voltage under the same volume. From a technical point of view, under the same size, it can pass more Large current, adapt to higher frequency, can obtain higher quality factor. However, compared to the traditional round copper wire winding, the assembly of the flat copper wire winding is more difficult, and the application in the domestic market is not wide at present.
因为为了保证扁铜线绕组的性能，需要尽可能的布置多层扁铜线，但是在有限的空间内，为了让多层扁铜线相互之间不产生干涉，需要每层的扁铜线之间要有相应的避让，这样一来就导致布置的扁铜线的形状变得很复杂，如图2a和图2b所示，目前是将扁铜线制成空间型的发卡状，并且该空间型发卡状的扁铜线在弯部过渡段101中还具有台阶部102。Because in order to ensure the performance of the rectangular copper wire winding, it is necessary to arrange the multilayer rectangular copper wire as much as possible. However, in a limited space, in order to prevent the multilayer rectangular copper wire from interfering with each other, the rectangular copper wire of each layer is required. Corresponding avoidances must be made between the spaces, which will cause the layout of the rectangular copper wire to become very complicated, as shown in Figure 2a and Figure 2b. At present, the rectangular copper wire is made into a spatial hairpin shape, and the space The flat copper wire in the shape of a hairpin also has a step 102 in the transition section 101 of the bend.
上述空间型发卡状的扁铜线在制作时通常是通过以下两种方式成型，一种是先通过简单的弯折机构将直线状的扁铜线弯折成平面型发卡状的扁铜线(如图1所示)，再通过人工将平面型发卡状的扁铜线手工制成空间型发卡状的扁铜线(如图2a和图2b所示)；另一种是直接通过人工将直线状的扁铜线手工制成空间型发卡状的扁铜线。The above-mentioned spatial hairpin-shaped rectangular copper wire is usually formed by the following two methods during production. One is to first bend the linear rectangular copper wire into a flat hairpin-shaped rectangular copper wire through a simple bending mechanism ( As shown in Figure 1), the flat hairpin-shaped flat copper wire is manually made into a space-shaped hairpin-shaped flat copper wire (as shown in Figure 2a and Figure 2b); the other is to directly manually make the straight line Shaped rectangular copper wire is hand-made into spatial hairpin-shaped rectangular copper wire.
上述两种成型方式，人工参与度极大，很难保证空间型发卡状扁铜线制成后产品的一致性，并且存在效率低、工人劳动强度大的缺点。The above two molding methods have a great degree of manual participation, and it is difficult to ensure the consistency of the product after the space-type hairpin-shaped flat copper wire is made, and there are disadvantages of low efficiency and high labor intensity of workers.
发明内容Summary of the invention
本发明的目的在于提供一种扁铜线弯折成型装置，能够代替人工将平面型发卡状的扁铜线制成空间型发卡状的扁铜线，降低了人工参与度，提高了产品质量和生产效率。The purpose of the present invention is to provide a flat copper wire bending and forming device, which can replace manual flat hairpin-shaped flat copper wires into space-type hairpin-shaped flat copper wires, reduce manual participation, and improve product quality and Productivity.
为此，本发明采用了以下技术方案：To this end, the present invention adopts the following technical solutions:
