Technical Field

[0001] The utility model generally relates to the field of fiberglass board manufacturing, and particularly relates to a pressure device for fiberglass boards. Background Technique

[0002] A press is a general-purpose press with delicate structure. It has the characteristics of wide application and high production efficiency. The press can be widely used in processes such as cutting, punching, blanking, bending, riveting, and forming. By applying a strong pressure to metal blanks, the metal undergoes plastic deformation and fracture to be processed into parts. Fiberglass boards are synthesized from fiberglass materials and high heat-resistant composite materials, and do not contain asbestos components harmful to the human body. They have high mechanical properties and dielectric properties, good heat resistance and moisture resistance, and good processability. Since the fiberglass separator is composed of multiple layers of boards laminated together, a press is required to apply pressure to the fiberglass separator during the production process to press them together.

[0003] Chinese Patent CN115320150B discloses a press for fiberglass separator production, which uses a pressing plate to press the fiberglass board. However, when the upper die and the lower die are pressed and closed, the edges of the upper die and the lower die may be separated, resulting in defects on the edges of the fiberglass board and affecting the yield rate.

[0015] Please refer to Figure 1 and 2, the glass fiber board pressing device of the present utility model includes a pressing edge mechanism 100, an upper pressing die mechanism 200 and a lower pressing die mechanism 300. The lower pressing die mechanism 300 includes a lower pressing die frame 310, a lower fixing frame 320 and a plurality of first oil cylinders 330. The lower pressing die frame 310 is fixedly connected with a lower pressing die. The first oil cylinder 330 includes a first cylinder body and a first piston rod. The first cylinder body is fixedly connected with the lower fixing frame 320, and the first piston rod is fixedly connected with the lower pressing die frame 310. The upper pressing die mechanism 200 includes an upper pressing die frame 210, an upper fixing frame 220 and a plurality of second oil cylinders 230.

The pressing edge mechanism 100 includes a first pressing edge claw 110 and a second pressing edge claw 120. The first pressing edge claw 110 and the second pressing edge claw 120 are respectively rotatably connected with the lower fixing frame 320. The first pressing edge claw 110 is driven by a plurality of first air cylinders 111, and the second pressing edge claw 120 is driven by a plurality of second air cylinders 121. The first pressing edge claw 110 and the second pressing edge claw 120 respectively abut against the edge of the upper pressing die.

[0016] In an embodiment of the present utility model, the lower pressing die mechanism 300 includes a lower pressing die frame 310, a lower fixing frame 320 and a plurality of first oil cylinders 330. The first cylinder body is fixedly connected with the lower fixing frame 320, and the first piston rod is fixedly connected with the lower pressing die frame 310. The first piston rod is fixedly connected with the bottom fixed wheel of the lower pressing die frame 310, which can play a supporting role for the lower pressing die frame 310. Four first oil cylinders 330 can be provided to ensure the stability of supporting the lower pressing die frame 310. When pressing the glass fiber board, the material is placed in the lower pressing die. After the upper pressing die and the lower pressing die are closed, the piston rods of the plurality of second oil cylinders 230 synchronously extend, and a pressing force is generated between the upper pressing die and the lower pressing die. After the pressing is completed, the piston rods of the plurality of second oil cylinders 230 synchronously contract, and the pressing force between the upper pressing die and the lower pressing die is released.

[0017] The upper pressing die mechanism 200 includes an upper pressing die frame 210, an upper fixing frame 220 and a plurality of second oil cylinders 230.

When pressing the glass fiber board, the second piston rod extends, and the second oil cylinder 230 drives the upper pressing die frame 210 to rotate, so that the upper pressing die is directly opposite to the lower pressing die. After the glass fiber board is pressed, the second piston rod contracts, and the second oil cylinder 230 drives the upper pressing die frame 210 to rotate, so that the upper pressing die is separated from the lower pressing die, and the lower pressing die is exposed, which is convenient to take out the glass fiber board from the lower pressing die.

[0018] When using the upper mold and the lower mold to close the mold to press the fiberglass board, the first edge pressing claw 110 and the second edge pressing claw 120 respectively abut against the edge of the upper mold, avoiding the separation of the edges of the upper mold and the lower mold, and improving the yield rate. The first edge pressing claw 110 is driven by a plurality of first air cylinders 111, and the second edge pressing claw 120 is driven by a plurality of second air cylinders 121, which can ensure the action speed of the first edge pressing claw 110 and the second edge pressing claw 120. Of course, the lower mold can be placed on the lower mold frame 310, and the lower mold frame 310 can play a good supporting role for the lower mold.

[0019] Furthermore, the upper fixing frame 220 and the lower fixing frame 320 are connected by a connecting frame 400.

[0020] In the embodiment of the present utility model, by providing the connecting frame 400, the upper fixing frame 220 and the lower fixing frame 320 are integrated into one body, ensuring the overall strength.

[0021] Furthermore, the first edge pressing claw 110 is provided with a first avoidance cavity 112, and the upper mold and the lower mold are respectively partially placed in the first avoidance cavity 112.

[0022] In the embodiment of the present utility model, by providing the first avoidance cavity 112, when the upper mold and the lower mold are closed and the first edge pressing claw 110 presses against the edge of the upper mold, the upper mold and the lower mold are respectively partially placed in the first avoidance cavity 112, avoiding the contact between the first edge pressing claw 110 and the upper mold or the lower mold.

[0023] Furthermore, the second edge pressing claw 120 is provided with a second avoidance cavity 122, and the upper mold and the lower mold are respectively partially placed in the second avoidance cavity 122.

[0024] In the embodiment of the present utility model, by providing the second avoidance cavity 122, when the upper mold and the lower mold are closed and the second edge pressing claw 120 presses against the edge of the upper mold, the upper mold and the lower mold are respectively partially placed in the second avoidance cavity 122, avoiding the contact between the second edge pressing claw 120 and the upper mold or the lower mold.

[0025] Furthermore, one end of the first air cylinder 111 is rotatably connected to the lower fixing frame 320, and the other end of the first air cylinder 111 is rotatably connected to the first edge pressing claw 110.

[0026] In the embodiment of the present utility model, one end of the first air cylinder 111 is rotatably connected to the lower fixing frame 320, and the other end of the first air cylinder 111 is rotatably connected to the first edge pressing claw 110. When the first air cylinder 111 acts, it can drive the first edge pressing claw 110 to move along, ensuring the stability of the movement of the first edge pressing claw 110.

[0027] Further, one end of the second cylinder 121 is rotatably connected to the lower fixing frame 320, and the other end of the second cylinder 121 is rotatably connected to the second edge pressing claw 120.

[0028] In an embodiment of the present utility model, one end of the second cylinder 121 is rotatably connected to the lower fixing frame 320, and the other end of the second cylinder 121 is rotatably connected to the second edge pressing claw 120.

[0029] Further, the first edge pressing claw 110 includes a first pressing block 113 and multiple first fixing pieces 114. The multiple first fixing pieces 114 are respectively fixed by a plurality of first connecting blocks 115, and the multiple first fixing pieces 114 are respectively fixedly connected to the first pressing block 113.
