如图1～图8所示，一种复底锅，包括锅体1，锅体1的底端开设有底口2，底口2的底端设有复底片3，且复底片3的直径与底口2的直径大小完全相同，复底片3的顶端设有一组球形环块4，底口2的顶端开设有一组球形卡槽5，且球形环块4均位于球形卡槽5内，球形卡槽5的顶端固接有环形块6，环形块6两侧的底端均固接有环形斜块7，且环形斜块7与环形块6为一体式结构，球形环块4的顶端均开设有T形槽8，且环形块6和环形斜块7均位于 T形槽8内。
在工作时，将复底片3放置在底口2上，利用油压机挤压复底片3，使得复底片3向下移动，复底片3带动球形环块4下移，被压入球形卡槽5内，且环形斜块7受到T形槽8竖直端的作用，环形斜块7的顶端向环形块6靠近，而后环形块6与环形斜块7进入T形槽8的竖直端内，当环形斜块7进入T形槽8的水平端后，环形斜块7形状发生恢复，环形斜块7的顶端向外侧恢复，紧紧的抵住T形槽8水平端的顶部，此时复底片3被固定，进而该结构利用油压机，将球形环块4压入球形卡槽5内，并且环形斜块7受到T形槽8竖直端的挤压，环形斜块7的顶端向环形块6一侧靠近，发生形变，而后进入T形槽8内，并在进入T形槽8的水平端内部后，环形斜块7形变恢复，环形斜块7的顶端抵住T形槽8水平端的顶部，此时复底片3被固定，在长时间使用以及激烈碰撞后，复底片3不会出现脱落的情况发生，延长了使用寿命。
如图2、图5和图6所示，底口2的顶端焊接有一组环形导热块9，且环形导热块9的数量至少为两块，底口2顶端的中部焊接有圆形导热块10，复底片3的顶端固接有一组方形环块11，且球形环块4与方形环块11的顶端固接，球形环块4与方形环块11为一体式结构，相邻环形导热块9与环形导热块9和圆形导热块10之间均设有环形空部12，方形环块11均位于环形空部12内。环形空部12的尺寸与方形环块11的尺寸完全相同，球形环块4的底端直径与环形空部12的直径完全相同，且球形环块4的直径由底端到顶端逐渐变大再变小，方形环块11能够完全将环形空部12填满，避免出现环形空部12受热膨胀的情况发生，且相贴合的方形环块11与环形导热块9，有利于加快导热性能，将球形环块4压入球形卡槽5内，能够实现复底片3的稳固性，提高涨紧连接，增加了铆合的牢固度和稳定性。
在工作时，电磁灶对复底锅底部加热，热量容易聚集在复底锅底端的中 部，圆形导热块10能够将热量传递至方形环块11，方形环块11将热量传递给环形导热块9，环形导热块9再通过锅体1的底端传递至锅体1的内部，避免热量聚集于一处，同时增加了高导热性，改善锅具的导热性能和锅底的导热均匀性，避免产生局部高温。
如图2、图4和图5所示，底口2顶端的中部开设有三角定位槽13，复底片3顶端的中部固接有三角定位块14，圆形导热块10的中部开设有穿孔15，且三角定位块14的顶部穿过穿孔15并位于三角定位槽13内，三角定位槽13与三角定位块14的形状的设计，能够快速实现复底片3与底口2的定位以及球形环块4与球形卡槽5的定位。三角定位槽13的顶端高于球形卡槽5的顶端，先将三角定位块14的顶端对准三角定位槽13，方便定位。
如图2、图4、图7和图所示，锅体1底端的外侧周向开设有一组凹槽16，复底片3的外侧周向固接有一组配合块17，且配合块17均位于凹槽16内。配合块17的设计，有利于增加复底片3与电磁灶之间的接触面积，提高受热均匀性，凹槽16的顶端均固接有限位块19，且限位块19的底端位于锅体1底端的底部，配合块17的顶端均开设有通口18，且通口18底端的两侧均开设有平面口20，复底片3放于底口2内，此时配合块17正好对应凹槽16，限位块19对应通口18，油压机下压复底片3，配合块17完全进入凹槽16内，限位块19进入通口18内，并穿过通口18，在油压机的作用下，限位块19受到挤压，限位块19的底端被压入平面口20内，此时限位块19形变呈T性，避免在受热冷缩后，配合块17发生形变，导致配合块17发生折弯的情况发生，对其进行固定。锅体1的底端、复底片3的底端、配合块17的底端和限位块19的底端相平齐，平面状态的底端，不会出现划伤电磁灶的情况发生，同时更加方便人们的实用。
一种复底锅的制造方法，包括以下步骤，
S1：利用模具压铸成型铝质锅，使锅体1底部预先成型有底口2和与球 形环块4相匹配的球形卡槽5，以及与配合块17相匹配的凹槽16，并且球形卡槽5顶端成型环形块6和环形斜块7；
S2：将环形导热块9和圆形导热块10焊接在底口2的顶部，且环形导热块9和环形导热块9与环形导热块9和圆形导热块10之间均留有环形空部12，圆形导热块10中部通过冲压机冲孔有穿孔15；
S3：复底片3的顶端车出球形环块4和方形环块11，复底片3的外侧设有与凹槽16相匹配的配合块17，配合块17上设有与限位块19相匹配的通口18，通口18的底端设有平面口20，用于配合限位块19被挤压成型的形状；
S4：将步骤S2得到的复底片3进行清洗除油，然后打砂处理，步骤S4中的清洗除油是采用水清洗，将水升温至45～55℃进行清洗除油，打砂处理是采用46号白刚玉砂粒进行处理；
S5：将处理好的复底片3与锅体1底端的底口2定位，使球形环块4位于环形空部12处，三角定位块14插入三角定位槽13内，配合块17对准凹槽16，限位块19对准通口18，然后利用油压机进行冷挤压成型；
S6：取出物件，检查合格后即为成品。
