Detailed Description

The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Referring to fig. 1, the metal bipolar plate forming apparatus of the present invention includes a fixed mold 10, a movable mold 20, a lifting driving unit 30, a mounting plate 40, and a translation driving unit 50.

The movable mold 20 is movably located above the stationary mold 10. An output end of the elevation driving unit 30 is connected with a side of the movable mold 20 away from the fixed mold 10 for driving the movable mold 20 to move up and down, and the elevation driving unit 30 is installed on the installation plate 40. The output end of the translation driving unit 50 is connected to the mounting plate 40 for driving the mounting plate 40, the lifting driving unit 30 and the movable mold 20 to translate along the horizontal direction.

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

Referring to fig. 2, a plurality of first forming bumps 11 are protrudingly disposed on a top surface of the fixed mold 10 facing the movable mold 20, and a first forming groove 12 is disposed between adjacent first forming bumps 11. The movable mold 20 is provided with a plurality of second molding protrusions 21 protruding toward the bottom surface of the fixed mold 10, and second molding grooves 22 are formed between adjacent second molding protrusions 21.

The shape and width of the first forming projection 11 match with those of the second forming groove 22, and the shape and width of the second forming projection 21 match with those of the first forming groove 12. In the present embodiment, the first molding projection 11, the first molding groove 12, the second molding projection 21, and the second molding groove 22 are all rectangular parallelepiped in shape.

The second molding protrusion 21 of the movable mold 20 movably protrudes into the first molding groove 12 of the fixed mold 10, while the first molding protrusion 11 of the fixed mold 10 protrudes into the second molding groove 22 of the movable mold 20.

In operation, the lifting driving unit 30 drives the movable mold 20 to move downward, as indicated by arrow a, so that the first second forming protrusion 21 of the movable mold 20 extends into the first forming groove 12 of the fixed mold 10, and simultaneously, the first forming protrusion 11 of the fixed mold 10 extends into the first second forming groove 22 of the movable mold 20, so that the metal plate 100 forms the first concave-convex structure. In this process, the metal plate 100 needs to be adapted to the shapes of the first forming groove 12 and the second forming groove 22, and the portion of the metal plate 100 away from the first concave-convex structure is contracted toward the first concave-convex structure, as indicated by arrow b. This prevents the metal plate 100 from being stretch-thinned and even broken. Since the metal plate 100 has a maximum elongation coefficient, for example, 35%, if the metal plate 100 is elongated more than the maximum elongation coefficient, it may cause breakage.

Then, the translational driving unit 50 drives the movable mold 20 to move leftward by a predetermined distance, as shown by an arrow c, the movable mold 20 moves leftward by the predetermined distance which is the width of the first forming protrusion 11, when the first second forming protrusion 21 of the movable mold 20 is located above the second first forming groove 12 of the fixed mold 10, the lifting driving unit 30 drives the movable mold 20 to move downward, so that the second forming protrusion 21 extends into the second first forming groove 12 of the fixed mold 10, the second forming protrusion 21 of the movable mold 20 extends into the second first forming groove 12 of the fixed mold 10, and the second forming protrusion 21 plays a role in limiting a portion of the metal plate 100 with the formed first concave-convex structure. Thus forming a second relief structure. The portion of the metal sheet 100 remote from the second relief structure contracts towards the second relief structure.

By analogy, a plurality of concave-convex structures on the metal plate 100 are formed in sequence 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 manufactured, the middle portion has a plurality of concave-convex structures 110, and the two ends are provided with a plurality of positioning holes 120 and other matching shapes 130. The pilot hole 120 is drilled by a drill and the mating feature 130 is formed by a composite mold press fit.

Compared with the prior art, the metal bipolar plate forming device of the utility model comprises a fixed mould 10, a movable mould 20, a lifting driving unit 30, a mounting plate 40 and a translation driving unit 50; the movable mold 20 is movably located above the stationary mold 10. An output end of the elevation driving unit 30 is connected with a side of the movable mold 20 away from the fixed mold 10 for driving the movable mold 20 to move up and down, and the elevation driving unit 30 is installed on the installation plate 40. The output end of the translation driving unit 50 is connected with the mounting plate 40, so as to drive the mounting plate 40, the lifting driving unit 30 and the movable mold 20 to translate along the horizontal direction; a metal plate 100 is placed on the fixed mold 10; a plurality of first forming convex blocks 11 are arranged on the top surface of the fixed mould 10 facing the movable mould 20 in a protruding mode, and a first forming groove 12 is formed between every two adjacent first forming convex blocks 11; a plurality of second forming convex blocks 21 are arranged on the bottom surface of the movable mould 20 facing the fixed mould 10 in a protruding manner, and a second forming groove 22 is arranged between every two adjacent second forming convex blocks 21; the second molding protrusion 21 of the movable mold 20 movably protrudes into the first molding groove 12 of the fixed mold 10, and the first molding protrusion 11 of the fixed mold 10 movably protrudes into the second molding groove 22 of the movable mold 20. The structure is simple, the operation is simple, the cost is low and the working efficiency is high.
