Detailed ways

The specific embodiments of the present invention will be further described in detail below based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention here is not intended to limit the protection scope of the present invention.

Referring to FIG. 1 , the metal bipolar plate forming device provided by the present invention includes a fixed mold 10 , a movable mold 20 , a lift drive unit 30 , a mounting plate 40 and a translation drive unit 50 .

The movable mold 20 is movably positioned above the fixed mold 10 . The output end of the lift drive unit 30 is connected to the side of the movable mold 20 away from the fixed mold 10 for driving the movable mold 20 to move up and down. The lift drive unit 30 is mounted on the mounting plate 40 . The output end of the translation drive unit 50 is connected to the mounting plate 40 for driving the mounting plate 40 , the lift drive unit 30 and the movable mold 20 to translate in the horizontal direction.

The metal plate 100 is placed on the fixed mold 10 .

Referring to FIG. 2 , a plurality of first forming bumps 11 are protruded from the top surface of the fixed mold 10 toward the movable mold 20 , and there are first forming grooves 12 between adjacent first forming bumps 11 . A plurality of second forming bumps 21 are protruded from the bottom surface of the movable mold 20 toward the fixed mold 10 , and there are second forming grooves 22 between adjacent second forming bumps 21 .

The shape and width of the first forming bump 11 match the shape and width of the second forming groove 22 , and the shape and width of the second forming bump 21 match the shape and width of the first forming groove 12 . In this embodiment, the shapes of the first forming protrusion 11 , the first forming groove 12 , the second forming protrusion 21 and the second forming groove 22 are all rectangular parallelepipeds.

The second molding protrusions 21 of the movable mold 20 can movably protrude into the first molding grooves 12 of the fixed mold 10 , while the first molding protrusions 11 of the fixed mold 10 protrude into the second molding recesses of the movable mold 20 . in slot 22.

During operation, the lift drive unit 30 drives the movable mold 20 to move downward, as shown by arrow a, so that the first second molding bump 21 of the movable mold 20 extends into the first first molding groove of the fixed mold 10 In step 12, at the same time, the first first forming bump 11 of the fixed mold 10 protrudes into the first second forming groove 22 of the movable mold 20, so that the metal plate 100 forms the first concave-convex structure. During this process, since the metal plate 100 needs to adapt to the shapes of the first forming groove 12 and the second forming groove 22 , the part of the metal sheet 100 away from the first concave-convex structure shrinks toward the first concave-convex structure, as indicated by arrow b Show. This prevents the metal plate 100 from being stretched thin or even broken. Since the metal plate 100 has a maximum elongation coefficient, such as 35%, if the metal plate 100 is stretched to a degree greater than the maximum elongation coefficient, breakage may result.

After that, the translation drive unit 50 drives the movable mold 20 to move a predetermined distance to the left. As shown by arrow c, the movable mold 20 moves to the left for a predetermined distance equal to the width of the first forming bump 11 . When the second forming bump 21 is located above the second first forming groove 12 of the fixed mold 10 , the lift driving unit 30 drives the movable mold 20 to move downward, so that the second forming bump 21 protrudes into the second forming groove 12 of the fixed mold 10 . In the two first molding grooves 12, the second second molding protrusions 21 of the movable mold 20 protrude into the second first molding grooves 12 of the fixed mold 10, and the second molding protrusions 21 play a role in opposing Part of the metal plate 100 with the first concave-convex structure that has been formed has the function of limiting position. In this way, the second concavo-convex structure is formed. The portion of the metal sheet 100 away from the second concave-convex structure shrinks toward the second concave-convex structure.

By analogy, a plurality of concave-convex structures on the metal plate 100 are sequentially formed until the movable mold 20 is completely opposite to the fixed mold 10 , as shown in FIG. 3 .

Referring to FIG. 4 , after the metal plate 100 is fabricated, a plurality of concave-convex structures 110 are formed in the middle, and a plurality of positioning holes 120 and other matching shapes 130 are formed at both ends. The positioning hole 120 is drilled by a drill bit, and the matching shape 130 is formed by pressing a composite mold.

Compared with the prior art, the metal bipolar plate forming device of the present invention includes a fixed mold 10 , a movable mold 20 , a lift drive unit 30 , a mounting plate 40 and a translation drive unit 50 ; above. The output end of the lift drive unit 30 is connected to the side of the movable mold 20 away from the fixed mold 10 for driving the movable mold 20 to move up and down. The lift drive unit 30 is mounted on the mounting plate 40 . The output end of the translation drive unit 50 is connected to the mounting plate 40 for driving the mounting plate 40, the lift drive unit 30 and the movable mold 20 to translate in the horizontal direction; a metal plate 100 is placed on the fixed mold 10; the fixed mold 10 moves toward the movable mold 10. A plurality of first forming bumps 11 are protruded from the top surface of the mold 20 , and there are first forming grooves 12 between adjacent first forming bumps 11 ; the movable mold 20 is protruded from the bottom surface of the fixed mold 10 The second molding protrusions 21 have second molding grooves 22 between adjacent second molding protrusions 21 ; the second molding protrusions 21 of the movable mold 20 can movably extend into the first molding grooves of the fixed mold 10 In the groove 12 , the first forming protrusion 11 of the fixed mold 10 can movably protrude into the second forming groove 22 of the movable mold 20 .
