本国际申请基于在2016年11月11日向日本专利局申请的日本专利申请第2016-220659号主张优先权，本国际申请参考并引用日本专利申请第2016-220659号的全部内容。
技术领域
本公开涉及在使橡胶构件与金属构件的表面加热接合时使用的加热装置。
背景技术
例如，在专利文献1中记载的接合方法中，(a)在稳定器(stabilizer)等的金属构件上涂敷粘接剂后，(b)在涂敷该粘接剂的部位压接橡胶衬套的状态下，(c)对隔着该橡胶衬套配设在两侧的线圈通电，从而加热稳定器。

发明内容
发明要解决的问题
在专利文献1中记载的发明中，稳定器的配设有线圈的部位即稳定器的隔着橡胶衬套的两侧发热，在该部位产生的热量经由稳定器传导至稳定器与橡胶衬套之间的压接部。因此，使压接部上升至接合温度所需要的时间很可能变长。因而，加热工时以及加热时的电力消耗可能会增加。
此外，感应加热利用在金属构件中因感应而产生的电流(感应电流)的焦耳热损失进行加热，从而主要在金属构件的表面(例如，距离表面0.2mm左右的深度范围)发热。因此，在橡胶构件的两侧配设线圈来使金属构件发热的方法中，难以向金属构件与橡胶构件的接触位置高效地传导热。
优选本公开的一个方面提供能够高效地对金属构件与橡胶构件的接触位置进行加热的加热装置。
用于解决问题的手段
本公开的一个实施方式是在使橡胶构件与金属构件的表面加热接合时使用的加热装置。加热装置具有线圈部和铁芯部。线圈部构成为用于感应出磁场。铁芯部以跨过橡胶构件的方式且从金属构件的第一区域至第二区域的方式配设，并且贯穿线圈部。
因此，金属构件的位于第一区域和第二区域之间的部位，与铁芯部协同动作，构成因向线圈部通电而感应出的磁通所通过的磁路。因此，在金属构件的表面的与橡胶构件接触的部位(以下，称为接触部位)也产生感应电流。
即，在本公开中，并不是通过导热来加热接触部位，而是能够使接触部位发热，直接加热该接触部位。因此，能够高效地加热金属构件和橡胶构件的接触位置。
此外，本公开的“铁芯部”是磁化特性好的材质即可。因此，当然可以是铁制的材质，只要是磁化特性好的材质，也可以由铁以外的材质构成铁芯部。

具体实施方式
以下说明的“发明的实施方式”示出属于本公开的技术范围的实施方式的一个例子。即，权利要求书中记载的发明特定事项等并不限定于下述实施方式所示的具体构成或构造等。
以下，结合附图对本公开的实施方式进行说明。此外，各图所附的表示方向的箭头等是为了易于理解各图相互之间的关系而记载的。各图所附的箭头等(方向)并不限定本公开的范围。
对于至少附有附图标记并进行说明的构件或部位，除了事先说明了存在“1个”等的情况以外，至少设置1个。即，在没有事先说明存在“1个”等的情况下，该构件可以设置2个以上。
(第一实施方式)
本实施方式说明用于使橡胶衬套与汽车的稳定器加热接合的加热装置以及加热方法。图1所示的稳定器W1是金属构件的一个例子，是抑制车体侧倾的金属制造的扭杆状的构件。
图1所示的橡胶衬套W2是橡胶构件的一个例子，是大致圆筒状的橡胶制造的构件。此外，在本实施方式的橡胶衬套W2的外周面接合有金属制造的筒材P。筒材P在将橡胶衬套W2加热接合在稳定器W1上之前通过硫化接合等加热接合方式被接合。
1.加热装置的结构
如图1所示，加热装置1至少具有线圈部3和铁芯部5。线圈部3是电导线卷成线圈状而形成的，用于在通电时感应出磁场。
如图2所示，从通电用电源7向线圈部3接通预先决定的频率的交流电流。本实施方式的通电用电源7是逆变式的电源，变换为商用电源的频率再向线圈部3通电。此外，上述频率例如为60Hz～300Hz或60Hz～400Hz。
如图1所示，铁芯部5是铁基金属制造的构件，以跨过橡胶衬套W2的方式且从稳定器W1的第一区域至第二区域的方式配设，其一部分贯穿线圈部3。
具体地说，该铁芯部5具有第一铁芯部5A和一对第二铁芯部5B、5C，构成为大致C字状或大致U字状。第一铁芯部5A是贯穿线圈部3内的铁芯。一对第二铁芯部5B、5C分别从第一铁芯部5A的延伸方向两端向稳定器W1侧延伸。
如图2所示，本实施方式的铁芯部5由多片的电磁钢板ES隔着电绝缘体(未图示)层叠而成。而且，多片的电磁钢板ES的层叠方向是与第一铁芯部5A的延伸方向大致垂直的方向。
即，在与在线圈部3内产生的“磁场方向”大致垂直的方向上，也就是与各电磁钢板ES的板厚方向平行的方向上层叠有多片的电磁钢板ES。另外，在图2中，层叠方向与纸面左右方向大致平行。
在本实施方式中，成形为大致C字状或大致U字状的多片的电磁钢板ES在板厚方向上被层叠而构成铁芯部5。铁芯部5的端面也就是面向稳定器W1的部位，即一对第二铁芯部5B、5C的端面直接或间接地与稳定器W1接触。
此外，在本实施方式中，第二铁芯部5B、5C的端面隔着绝缘体制造的夹装体5D与稳定器W1间接接触。该夹装体5D是用于防止稳定器W1与铁芯部5相互摩擦从而损伤该稳定器W1的表面涂膜的构件。
2.本实施方式的加热装置的特征
本实施方式具有：线圈部3，用于感应出磁场；铁芯部5，以跨过橡胶衬套W2的方式且从稳定器W1的第一区域至第二区域的方式配设，并且贯穿线圈部3。
由此，稳定器W1的位于第二铁芯部5B与第二铁芯部5C之间的部位，即稳定器W1的贯穿橡胶衬套W2的部分，与铁芯部5协同动作，构成因向线圈部3通电而感应出的磁通所通过的磁路。
因此，在稳定器W1的表面的与橡胶衬套W2接触的接触部位也产生很多的感应电流。即，在本实施方式中，并非通过导热来间接加热接触部位，而是使接触部位发热从而直接加热该接触部位。因此，能够高效地加热稳定器W1与橡胶衬套W2的接触位置。
铁芯部5是多片的电磁钢板ES隔着电绝缘体层叠而形成的，多片的电磁钢板ES的层叠方向是与从第一区域朝向第二区域的方向垂直的方向。因此，能够抑制在铁芯部5产生不需要的涡流等。因而，能够高效地加热接触位置。
(第二实施方式)
如图3A以及图3B所示，在本实施方式中，将线圈部3和铁芯部5作为1组，并将多组的线圈部3和铁芯部5沿着稳定器W1的外周面配设。此外，与上述实施方式相同的构成要件等被赋予与上述实施方式相同的附图标记，因此省略重复的说明。
由此，能够均匀地加热稳定器W1的表面的与橡胶衬套W2接触的接触部位，并能够缩短加热时间，减少加热装置1的电力消耗量。
而且，在本实施方式中，因为电流分配给多个线圈部3，所以能够抑制各线圈部3的温度上升。
(第三实施方式)
如图4所示，在本实施方式中，铁芯部5的端面，即第二铁芯部5B、5C的端面由与稳定器W1的表面大致平行的面构成。此外，在图4中，省略夹装体5D。
由此，能够抑制铁芯部5与稳定器W1之间的间隙或接触位置的磁阻变大。进而，能够提高接触部位的磁通密度，因而能够高效地加热稳定器W1与橡胶衬套W2的接触位置。
与上述实施方式相同的构成要件等被赋予与上述实施方式相同的附图标记，因此省略重复的说明。此外，本实施方式当然也能够适用于第一实施方式。
另外，“第二铁芯部5B、5C的端面由与稳定器W1的表面大致平行的面构成”是指例如以下的情况等。
(a)稳定器W1的表面是圆筒面，第二铁芯部5B、5C的端面形成与该圆筒面所描绘的图形大致相似的圆的部分形状(圆弧)或整周形状。
(b)稳定器W1的表面是方筒面，第二铁芯部5B、5C的端面形成与该方筒面所描绘的图形大致相似的矩形的部分形状或整周形状。
此外，因为第二铁芯部5B、5C以层叠电磁钢板ES的方式构成，所以在稳定器W1的表面是圆筒面的情况下，难以使端面形成为光滑的圆弧状。
因此，该端面成为阶梯状变化的形状。而且，在本公开中，也将该端面是阶梯状等的情况称作“第二铁芯部5B、5C的端面由与稳定器W1的表面大致平行的面构成”。
(其它的实施方式)
在上述实施方式中，第二铁芯部5B、5C的端面隔着绝缘体制造的夹装体5D与稳定器W1间接接触。但是，本公开并不限定于此。
即，例如在稳定器W1上没有表面涂膜的情况下，或表面涂膜具有足够的强度的情况下，也可以不隔着夹装体5D，使第二铁芯部5B、5C的端面与稳定器W1直接接触。
上述实施方式的铁芯部5是在与线圈部3内产生的“磁场方向”垂直的方向上层叠多片的电磁钢板ES而形成的结构。但是，本公开并不限定于此。即，也可以由磁化特性好的材质例如S10C等的低碳钢制造的实心构件构成铁芯部5。
在上述实施方式中，向线圈部3接通60Hz～300Hz或60Hz～400Hz左右的低频率的交流电流。但是，本公开并不限定于此。即，例如，通电频率是根据加热对象物等的材质以及大小等适当选定的值。
在上述实施方式中，说明了用于使橡胶衬套与汽车的稳定器加热接合的加热装置。但是，本公开并不限定于此。
即，本公开也能够适用于其它金属构件与橡胶构件的接合。而且，可以在金属构件与橡胶构件的接合面涂敷粘接剂的情况下进行加热接合，也可以不在接合面涂敷粘接剂的情况下进行加热接合。
如上所示，上述稳定器W1是金属构件的一个例子。因此，作为金属构件的一个例子的稳定器W1当然并不限定于扭杆状。同样地，“杆”表示棒状的构件，并不仅表示为实心材料，因此“杆”也包括中空材料。
在上述实施方式中，筒材P在橡胶衬套W2与稳定器W1加热接合前通过硫化接合等加热接合的方式被接合。但是，本公开并不限定于此。即，可以在橡胶衬套W2与稳定器W1加热接合后再使筒材P接合。
本公开只要满足权利要求书所记载的发明的主旨即可，并不限定于上述实施方式。因此，可以将上述多个实施方式中的至少两个实施方式进行组合。

Claims (4)
