It please refers to shown in Fig. 1, Fig. 2, the forming method of the application ball-type contact is as follows:
The diagram length direction for defining sheet metal 10 is defined as X-direction, and the vertical X-direction upwardly direction is the side Y
To the vertical X, Y-direction are Z-direction.
S01, sheet metal 10 is provided, the sheet metal 10 is subjected to first time bending along Y-direction；
As shown in Figure 1A, in this step, after 10 bending of sheet metal, the first folding is formed on the sheet metal 10
Turn of bilge 21, from first bending part 21 extend the first extension 11, be formed in the second of 11 end of the first extension
Bending part 22 and from second bending part 22 extend to form to bending part 12；In this step, first extension 11 with
The sheet metal 10 is at an acute angle or obtuse angle, and described to bending part 12 is in a clamp diagonally downward and with the sheet metal 10
Angle；The figure in left side is bending schematic diagram of the bending jig to sheet metal in Figure 1A.
S02, to first extension in the Y direction upwards bending again；
As shown in Figure 1B, in this step, first extension 11 is continued up into bending, makes first extension 11
Between the sheet metal 10 in vertical state, at this point, described be located at the sheet metal 10 with being parallel to bending part 12
Upper side；
S03, will described to bending part 12, downward bending forms at the top of arc 13, third bending part 23 and the in the Y direction
Two extensions 14；
As shown in Figure 1 C, in this step, first extension 11 and the second bending part 22 is fixed in bending jig,
Meanwhile described 13, third bending part 23 and the second extension 14 at the top of arc will be formed to 12 downward bending of bending part.Described
One, the second extension 11,14 can be vertical or arcuate structure.
For step S01 into S03, the step of completion, is that bending forms a U on X/Y plane by the sheet metal 10
Type structure, the U-shaped structure carry out bending by tri- steps of step S01 to S03, sheet metal 10 are prevented to be broken.Each step
Rapid bending jig is shown on the left of Fig. 1.The U-shaped structure has certain width in z-direction.
S04, the U-shaped structure is formed into ball-type contact along the downward punching stretch of Y-direction in 360 degree of orientation；
As shown in Figure 2 A, in this step, be located at below the U-shaped structure by 40 jig of lower die bulb, then by with institute
The groove (not labeled) for stating the cooperation of bulb 40 is pressed down against the U-shaped structure along Y-direction from 360 degree of directions of XZ plane, makes institute
It states U-shaped structure to be finally stretched in bulb contact, and first, second extension 11,14 is made to be connected in one to be formed and close
The ring structure of conjunction.Top ultimately forms bulb where 13 at the top of the arc.
