Embodiment Construction
[0046] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:
[0047] see figure 2 , is a structural schematic view of an embodiment of the sheet metal forming system of the present invention. As shown in the figure, the sheet metal forming system 20 includes a sealing die 21, a forming die 23 and a movable fluid input unit 25, wherein at least one sealing cavity 211 is arranged in the sealing die 21, and at least one forming cavity 211 is arranged in the forming die 23 cavity 231, and the movable fluid input unit 25 includes one or more input holes 251.
[0048] The movable fluid input unit 25 is located on the sealing mold 21 , and the input hole 251 of the movable fluid input unit 25 is located in the sealing cavity 211 or the molding cavity 231 . The movable fluid input unit 25 can be displaced relative to the sealing mold 21. During the displacement process of the movable fluid in...

The invention discloses a sheet metal molding system which mainly comprises a forming die, a sealing die and a movable fluid input unit, wherein the forming die comprises a forming cavity, and the sealing die comprises a sealing cavity. When the system is used, sheet metal can be arranged between the sealing die and the molding die, and pressure is applied onto the sealing die and the molding die, so that a closed cavity is formed by the sealing cavity and the molding cavity. The movable fluid input unit can be used for conveying fluid into the sealing cavity, and the sheet metal is pressed by the pressure of the fluid in the sealing cavity, so that the sheet metal deforms towards the direction of the molding cavity. Furthermore, the movable fluid input unit can shift relative to the sealing die, so that an input hole of the movable fluid input unit is close to the sheet metal and the sealing cavity, and the molding efficiency of the sheet metal is improved.
Description
technical field [0001] The invention relates to a sheet metal forming system. During the forming process, a movable fluid input unit can gradually approach the sheet metal so as to improve the forming efficiency of the sheet metal. Background technique [0002] see figure 1 Shown is a structural schematic diagram of an existing sheet metal forming system. As shown in the figure, the existing sheet metal forming system 10 includes a sealing die 11 and a forming die 13 , wherein a sealing cavity 111 is disposed in the sealing die 11 , and a forming cavity 131 is disposed in the forming die 13 . [0003] The sealing mold 11 is connected to a gas booster pump 153 through a gas delivery tube 151 , and the gas booster pump 153 can input the gas 14 into the sealing cavity 111 through the gas delivery tube 151 . In addition, an electric heating tube 17 is provided around the sealing mold 11 and the forming mold 13 , and the electric heating tube 17 can be used to heat the sealing ...
