Embodiment approach 1
[0068] [Embodiment 1: Single process]
[0069] As Embodiment 1, for example, it is possible to use figure 1 The device shown was molded. Specifically, the heated steel plate 1 and another steel plate 2 corresponding to a reinforcing member are stacked and placed on the support table 3, and then air-cooled to the joining start temperature, and the punching punch built in the joining punch 6 is 11 descends and joins at the same time as stamping. figure 1 Shows the state of reaching the bottom dead center. In this Embodiment 1, as figure 1 As shown, while press forming is performed using a punching die 8 , a base 9 , and a punch 11 for punching, joining is performed using a joining die 4 and a joining punch 6 built in the base 9 .
Embodiment approach 2
[0070] [Embodiment 2: Multi-process]
[0071] As Embodiment 2, for example, figure 2 Molded as shown. exist figure 2 In the process, after heating the steel plate, proceed continuously figure 2 The first step shown in (a), figure 2 the second step shown in (b), and figure 2 The third step shown in (c). Each step will be described. First, in the first process, the heated steel plate 1 is arranged on the support table 3, and then the punch 10 for giving the remaining wire length is lowered, as shown in FIG. figure 2 As shown in (a), the remaining wire length is given to the steel plate 1 constituting the outer wall of the component. Next, in the second step, another steel plate 2 is placed on the steel plate 1 to which the remaining wire length has been given, and the punch 6 for joining is lowered, as shown in FIG. figure 2 As shown in (b), joining at two positions is performed using the joining punch 6 and the joining die 4 built in the pressing die 8 to obtain ...
Embodiment 1
[0120] For steel plate A and steel plate B satisfying the composition shown in Table 3, prepare two test pieces with dimensions of 150mm×50mm×thickness 1.4mm respectively, and use image 3 The devices shown have a mechanical scarf joint. In detail, in image 3 In this method, the steel plate 1 heated at 930° C. for 4 minutes and the other steel plate 2 are stacked in a cross shape, and placed at the joint between the joining punch 6 provided on the joining punch jig 7 and the joining die jig 5 . After using the support table 3 between the dies 4, air-cooled to the following bonding start temperature, the above-mentioned bonding die 4 was lowered, and mechanical engagement was performed under the following conditions to obtain a test material corresponding to a part.
