本発明は導電性の被接合材の接合部を通電加熱
による抵抗発熱と加圧による塑性変形によつて一
体化する加熱圧接機に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a heat pressure welding machine that integrates conductive materials to be joined by resistance heat generation by current heating and plastic deformation by pressurization.
一般に銅と銅あるいは銅とアルミニウム等、導
電性母材同志を接合する方法としては種々のもの

かにある。
In general, there are various methods for joining conductive base materials such as copper and copper or copper and aluminum, but the principle of joining is how to keep the joint clean and the atoms of the conductive base materials to be joined. By applying some energy to the like-minded arrangement, high quality joints can be obtained much more easily.
そしてこれらの接合方法にはエネルギーの加え
方によつて種々のものがある。すなわち接合部の
材料が固相であるか液相であるかあるいは加圧が
必要か否かによつて融接接合法、圧接接合法およ
びろう接接合法に分けられる。 There are various joining methods depending on how energy is applied. That is, the methods are divided into fusion welding, pressure welding, and soldering, depending on whether the material of the joint is solid or liquid, or whether pressure is required.

た面にしか発生しない。このため従来の評価方法
としては破壊試験で確認し、確率的に保証するよ
うにしているのが一般的である。 The above pressure welding method is different from the other two joining methods,
This is a method that attempts to integrate the base materials to be joined by applying pressure or heating and pressurizing, and the non-destructive inspection technology of the joints used in the other two joining methods can be used to evaluate the quality of the joints. Difficult to apply. That is, when joining is performed using other fusion welding methods or braze joining methods, the structure at the joint becomes coarse due to melting and there are dissimilar materials, resulting in some kind of discontinuity. On the other hand, in the pressure welding method, the parts are joined by applying pressure or a combination of applying pressure and heating, so that the joined parts are integrated and some discontinuities occur only on very limited surfaces. For this reason, the conventional evaluation method is to confirm by destructive testing and to guarantee it probabilistically.

According to the above configuration, when welded using the heat pressure welding method with good reproducibility, the joint is very narrow and the same type of material is integrated. It has been difficult to determine quality guarantees other than probabilistically guaranteeing that it is only necessary to obtain a certain number of identical results. However, in the future, the heat pressure welding method will be used more often for high-quality joints, and a higher grade of quality than before is required, so it is necessary to stabilize the quality of each joint.

A first embodiment of the present invention will be described with reference to FIG. FIG. 1 is a diagram showing a schematic configuration of a heat pressure welding machine. Reference numerals 1 and 2 in the figure indicate conductive members to be joined. The members 1 and 2 to be joined are both made of copper, which is a non-ferrous metal, and are configured to be pressed in the direction indicated by the arrow in the figure by a pressure welding mechanism (not shown). The members 1 and 2 to be joined are restraint clamps 3
and 4, respectively. The restraint clamps 3 and 4 are configured to also serve as current-carrying electrodes. An energization power source 6 as an energization heating mechanism is connected to the restraining clamps 3 and 4 via an energization control setting device 5 as an energization control mechanism. The energization control setting device 5 is configured to set an appropriate current value determined from the materials of the materials 1 and 2 to be joined, the balance of the joint surfaces, the surface roughness, and the cross-sectional state. Also, code 7 in the figure
shows a speed setting device as a deformation speed setting mechanism.
This speed setting device 7 is configured to set the deformation speed E p of the joint portion necessary for heat pressure welding. A speed measuring mechanism 8 is provided near the joint between the materials 1 and 2 to be joined. This speed measuring mechanism 8 is composed of a displacement measuring device 9 that measures the displacement of the joint, and a speed calculator 10 that calculates the deformation speed E s of the joint based on the measured value of the displacement measuring device 9. There is.
The deformation speed E s measured by the speed calculator 10 and the deformation speed E p set by the speed setting device 7 are compared by a comparator 11 as a comparison mechanism. The comparator 11 is configured to output a signal to the energization control setting device 5 to stop the energization when the measured deformation speed Es reaches the set deformation speed Ep . At this time, the primary pressurization by the pressure contact mechanism is switched to secondary pressurization.

経過後２次加圧が停止され加熱圧接が終了する。 According to the above configuration, first, an appropriate current value is set at the joint portion of the materials 1 and 2 by the energization control setting device 5. Then, energization by the energizing power source 6 is started, and at the same time, primary pressurization by the pressure contact mechanism is started. As a result, the joint portions of the materials 1 and 2 to be joined are welded under heat and pressure. At that time, the displacement of the joint is measured by the displacement measuring device 9, and based on this measurement, the deformation speed E s of the joint is calculated by the speed calculator 10.
Enter 1. The comparator 11 compares this deformation speed E s with the deformation speed preset by the speed setting device 7.
The deformation speed E s is set by comparing the deformation speed E p with E p
When reaching this point, a signal is output to the energization control setting device 5 to stop the energization. This signal stops energization. At the same time, secondary pressurization by the pressure welding mechanism is started, causing the material on the joint surface to flow out in the outer circumferential direction. and a predetermined time (e.g. 0.1 seconds or less)
After the elapse of time, the secondary pressurization is stopped and the heat pressure welding is completed.

質の高い接合部を確実に提供することができる。 Next, the above heat-pressing process will be described with reference to time charts shown in FIGS. 2 and 3. FIG. 2 shows the case using the conventional heat pressure welding method, and FIG. 3 shows the case according to this embodiment. And A in Figure 2
3 indicates position set, B indicates pressurization, and C indicates energization. In FIG. 3, B' indicates pressurization, and C' indicates energization. Conventionally, primary pressurization, energization, and secondary pressurization were controlled based on the amount of plastic deformation of the materials to be joined. That is, the joining process is controlled by the amount (position) of plastic deformation of the materials to be joined, and first, the primary pressure deformation position is set. and,
When the materials to be joined are deformed by the heating and primary pressurization caused by the energization and reach the preset primary pressurization deformation position, the energization is stopped and the secondary pressurization is started. Then, after a predetermined period of time has elapsed, the secondary pressurization is stopped and the hot press welding process is completed. In contrast, in this embodiment, the speed setting device 7 sets the deformation speed E p of the welded portion of the materials 1 and 2 in advance, and the actual deformation speed E s measured by the speed measuring device 9 is set in advance. This deformation speed E s is the deformation speed above.
Since energization and switching from primary pressure to secondary pressure are performed when E p is reached, it is possible to eliminate factors that worsen the positional deviation of the joint, such as positional deviation due to variations in the joint surface. As shown in FIG. 3, since the pressure B' is controlled by the energization C', positional or temporal deviations may occur in the state of the bonded surfaces. Stable quality of the joint can be obtained.
Then, it is sufficient to obtain a certain number of identical results while evaluating and confirming with destructive tests as in the past.
Unlike the case where quality is guaranteed probabilistically, a deformation speed that can guarantee quality is set in advance,
Thereby, the same quality can be guaranteed and high quality joints can be reliably provided.

and a speed calculator 15 for calculating the speed. The displacement measuring device 14 is configured to measure the amount of movement of the restraint clamp 4, and the speed calculator 15 calculates the deformation speed Es based on this amount of movement.

That is, in contrast to the movement amount of the restraint clamp 4 that was measured in the third embodiment, the movement amount of the pressurizing cylinder (not shown) of the pressure welding mechanism was measured by the displacement measuring device 16, and based on this movement amount.

The configuration is such that the deformation speed E s is calculated by inputting the The subsequent operations are the same as in the first to fourth embodiments. In the second to fifth embodiments described above, the same effects as in the first embodiment can be achieved, and high-quality joints can be automatically and easily obtained.
