Abstract

本发明公开了一种矩形线圈压装工艺，该工艺包括以下步骤：用压装工具将矩形线圈内径撑紧；在矩形线圈的四个侧面上分别放置板，位置相对的两个板之间用螺杆拉紧；对拉位置相对的两面上的板，使得矩形线圈在长度和宽度两个方向上符合图纸要求；在矩形线圈的上下两个表面上设置两个“十”字形支撑板，且两个“十”字形支撑板之间螺栓连接；收紧两个“十”字形支撑板之间螺栓，使得矩形线圈在高度方向上符合图纸要求，这样的压装工艺保证了矩形线圈的外径，进而保证了线圈的质量。

Description

矩形线圈压装工艺
技术领域
本发明涉及一种矩形线圈压装工艺。
背景技术
矩形线圈在绕制时虽然辐向带了一定的张力，但其不易成型，线圈外径偏大，达不到技术要求，由于非晶合金变压器线圈采取的是高低压合绕的形式，所以若低压线圈的外径不能保证，那么高压线圈的尺寸同样也不能保证，更不能保证产品质量。
发明内容
本发明提供一种能够控制矩形线圈外径的矩形线圈压装工艺。
本发明采用如下技术方案：
一种矩形线圈压装工艺，包括以下步骤：
①用压装工具将矩形线圈内径撑紧；
②在矩形线圈的四个侧面上分别放置板，位置相对的两个板之间用螺杆拉紧；
③对拉位置相对的两面上的板，使得矩形线圈在长度和宽度两个方向上符合图纸要求；
④在矩形线圈的上下两个表面上设置两个“十”字形支撑板，且两个“十”字形支撑板之间螺栓连接；
⑤收紧两个“十”字形支撑板之间螺栓，使得矩形线圈在高度方向上符合图纸要求。
与现有技术相比，本发明具有以下优点：
本发明能够控制矩形线圈的外径。非晶合金低压线圈在绕制完后，脱模，将线圈竖立，此时选择合适的压装工具将矩形线圈的内径撑紧，然后在线圈的四个侧面放置板，面面相对的板之间用螺杆拉紧，两面对拉，直至使矩形线圈在长度和宽度两个方向上符合图样要求；然后选用合适的十字形支撑板，将十字形支撑板放置在矩形线圈的上下表面，再在十字形支撑板中穿入螺杆，然后收紧螺杆，直至矩形线圈在高度方向上符合图纸要求，这样就能够保证矩形线圈在后续处理如：干燥、浸漆工艺过程中，保证其外径不会发生变化，进而保证了矩形线圈的质量。
具体实施方式
一种矩形线圈压装工艺，包括以下步骤：
①用压装工具将矩形线圈内径撑紧；
②在矩形线圈的四个侧面上分别放置板，位置相对的两个板之间用螺杆拉紧；
③对拉位置相对的两面上的板，使得矩形线圈在长度和宽度两个方向上符合图纸要求；
④在矩形线圈的上下两个表面上设置两个“十”字形支撑板，且两个“十”字形支撑板之间螺栓连接；
⑤收紧两个“十”字形支撑板之间螺栓，使得矩形线圈在高度方向上符合图纸要求。
在本实施例中，在矩形线圈的四个侧面上分别放置的板可以为环氧板、钢板等，在矩形线圈的上下两个表面上设置两个“十”字形支撑板时，需要用“十”字形支撑板压住矩形线圈出线头，这样就能够避免在压装过程中损坏矩形线圈的出线头，将矩形线圈压装工艺完成后，便按照按现行的干燥、浸漆工艺将矩形线圈进行干燥、浸漆，然后再检查高压绕线模具，确保其强度达到产品图样要求，将绕线模具放入低压线圈绝缘筒内，端面要平齐，按图纸规定上好套好绕线模的低压线圈，并将其固定在主轴上，即可以开始绕制高压线圈。
