本实施例中，所述固溶炉上料机构1、固溶炉积料机构2、固溶加热炉3、淬火机构4、倒水机构5、时效加热炉6、时效炉积料机构7以及时效炉下料机构8呈平面直线型布置。
具体工作过程：
当无料筐热处理生产线开始工作时，将工件放置在固溶加热炉3进料口前的传输辊道11上，工件在传输辊道8的辊棒传动作用下传递到固溶炉上料机构1上，固溶炉上料机构1在电机的带动下将工件分别传输给固溶炉炉前积料机构2的上、中、下三层传动辊10上；固溶炉炉前上料机构1运动到固溶加热炉3的炉门前端，固溶炉炉前积料机构2上的传动辊10转动并将工件传输到固溶加热炉3内，此时固溶加热炉3内辊棒9是呈现运动状态；当工件在固溶加热炉3内加热后运行到固溶加热炉3出料口时，工件传送到淬火机构4中的淬火架上，当工件布满淬火架传动平台41的上、中、下时，淬火架下降，将工件完全浸没在淬火槽中进行淬火处理，工件淬火处理完成后，淬火机构4中的淬火架上升，并将工件传递给倒水机构5，当淬火后的工件全部运输到倒水机构5上时，倒水机构5在电机的带动下做翻转运动，让 淬火后工件上的残留淬火液从工件表面流淌到淬火槽中，待工件表面的淬火液基本去除后，移动倒水机构5翻转，使传动平台51与时效加热炉内辊棒9齐平，工件在倒水机构5的传动下，运行到时效加热炉6内的辊棒上，此时时效加热炉6内的辊棒是呈现运动状态；工件在时效加热炉6中进行热处理后并运行到时效加热炉6出口处时，工件在时效加热炉6内的辊棒9带动下传输到时效炉炉前积料机构7上；时效炉下料机构8从时效炉炉前积料机构7上接取工件，并将工件放置在传输辊道15上，由传输辊道11将热处理后的工件传输到指定位置，时效炉下料机构8接取时效炉炉前积料机构7上的工件为层层接取的方式。
以上所述的仅是本发明的优选实施方式，应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
