    • PROBLEM TO BE SOLVED: To provide a joining tool which can improve the joining strength of the object to be joined after joining, and can further improve its fine appearance.
      SOLUTION: An annular recessed part 31 going round an axis is formed at the edge face part of each shoulder part 21. The deformed part of each object 3 to be joined extruded by a pin part 22 moves toward each annular recessed part. Since the pin 22 is formed so as to be a conical-trapezoidal shape, the object to be joined can be extruded also by the circumferential face part in the pin part 22 as well as the edge face parts thereof, and the deformed part of the extruded object to be joined is made easy to be moved toward the annular recessed part, and, even if rugged shape is not formed on a backing member 14, each boss part 4 for generating calking action on the object to be joined after the deformation can be largely formed. Thus, the improvement of its strength by calking deformation can be attained together with friction stir joining without deforming the surface part of the object 3 to be joined on which the backing member 14 is abutted, and the joining strength of the object 3 to be joined after joining can be improved.

    • 要解决的问题:提供一种可以提高接合后待接合物体的接合强度的接合工具,并且可以进一步改善其精细外观。 解决方案:在每个肩部21的边缘部分处形成一个环绕圆周的环形凹陷部分31.由销部分22挤出的每个物体3的变形部分朝向每个环形凹部移动。 由于销22形成为圆锥形状,所以被接合物也可以通过销部22的周面部及其边缘面部分挤出, 被接合的被挤压物易于朝向环状凹部移动,即使在背面部件14上没有形成凹凸形状,也可以在变形后对被接合体产生铆接作用的各凸起部4, 主要形成。 因此,通过摩擦搅拌接合可以实现其强度的提高,而不会使背衬构件14所抵接的待接合物体3的表面部分变形,并且待接合物体3的接合强度 加盟后可以改善。 版权所有(C)2007,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide friction stir equipment capable of suppressing the unevenness of quality of an objective material, which is caused by the influence from disturbance such as an outside air temperature. SOLUTION: A controller determines a rotation resistance force around an axis exerted to a rotary tool 30 from a material 33 to be joined, based on the current value given to a motor for rotating the rotary tool 30, and judges, as a shoulder part contact time t2, the time when the rotation resistance force takes the maximum value. A travelling start time when the movement of the rotary tool 30 in the travelling direction is started is decided based on the shoulder part contact time t2. The state of friction stirring after the shoulder part contact time t2 is less influenced from the disturbance. Accordingly, by deciding a travelling start time t3 of the rotary tool 30 based on the shoulder part contact time t2, the travelling of the rotary tool 30 is started when a softening state reachs a stable just enough state, so that the quality of the material 33 to be joined is stabilized after joining.

    • PROBLEM TO BE SOLVED: To provide a friction stir equipment capable of suppressing the unevenness of quality of an objective material, which is caused by the influence from disturbance such as an outside air temperature. SOLUTION: A controller 253 determines a rotation resistance force around an axis exerted to a rotary tool 30 from a material 33 to be joined, based on the value of current flowing to a servo motor for rotating the rotary tool 30, and determines, as a shoulder part contact time t2, the time when the rotating resistance force takes the maximum value. Then, a travelling start time t4 when the rotary tool 30 is made to travel from the material 33 to be joined is decided based on the shoulder part contact time t2. The state of friction stirring after the contact time t2 has passed is less influenced by the disturbance. Accordingly, by deciding the travelling start time t4 based on the contact time t2, the rotary tool 30 can be traveled in a fixed friction stirring state with the influence of disturbance suppressed, so that the quality of the material 33 to be joined is stabilized after joining.

    • PROBLEM TO BE SOLVED: To provide a spot joining apparatus utilizing friction stir with which the deterioration of joined quality can be prevented. SOLUTION: The spot joining apparatus 1 is provided with a joining tool 5, a pressurizing means 8 and a receiving part 11. The pressurizing means 8 is provided with a spring member 16 and an annular pushing member 15. When a pressure imparting device 7 is moved down while rotating the joining tool with a motor 6 for rotation, firstly, the pushing member 15 in the pressurizing means 8 is abutted on two sheets of works W1, W2 disposed by piling up on the receiving member 11, and the pushing force is acted near the joining point. In this way, the works W1, W2 are closely stuck to eliminate any gap. Further, when the joining tool 5 is moved down while rotating, a pin 10 at the tip of the tool is inserted into the work while rotating, and a base metal is stirred. When the joining tool 5 is pulled up, the works are joined at the spot point and the pressure imparted by the pressurizing means 8 is released.
