The two ends of the fixed arc-shaped seat 221 are connected to the support frame 21, and the separated arc-shaped seat 222 is arranged at the bottom end of the fixed arc-shaped seat 221. The two ends of the connecting member 223 are detachably connected to the fixed arc-shaped seat 221 and the separated arc-shaped seat 222, respectively. After the bent plate shaping device has been used for a period of time, the bottom end of the arc-shaped positioning seat 22 will be deformed. The user can ensure that the shape of the bottom end of the arc-shaped positioning seat 22 remains within the standard range by replacing the separated arc-shaped seat 222, thereby increasing the processing yield of the bent plate material.

[0030] In this embodiment, a mounting groove is provided on the surface of the connection between the fixed arc seat 221 and the separation arc seat 222, and the connecting member 223 is disposed in the mounting groove. The two ends of the connecting member 223 are respectively connected to the outer surfaces of the fixed arc seat 221 and the separation arc seat 222 by bolts. In other embodiments, the connecting member 223 can connect the fixed arc seat 221 and the separation arc seat 222 by a detachable connection method commonly used by those skilled in the art, such as a pin and a fitting.

[0031] The fixing device 2 further includes two material discharging seats 23, which are respectively arranged at the two ends of the opening of the arc-shaped positioning seat 22, and a limiting member 231 is arranged on the same side of the two material discharging seats 23, and the two limiting members 231 are arranged on the outside of the arc-shaped positioning seat 22. The two material discharging seats 23 facilitate the user to place the bent plate material below the arc-shaped positioning seat 22, and the limiting member 231 determines the relative position of the bent plate material and the arc-shaped positioning seat 22. The material discharging seat 23 cooperates with the limiting member 231 to determine the placement position of the bent plate material, thereby ensuring the accuracy of the top pressing process.

[0032] The pressing device 3 is disposed on the base 1 through a through hole of the base 1 , and the top end of the pressing device 3 faces the opening of the arc-shaped positioning seat 22 .

[0033] See also Figure 5 , Figure 5 It is a structural schematic diagram of a top pressing device and a base according to an embodiment of the present invention.

[0034] The pressing device 3 includes a pressing cylinder 31 and a tooling pressing head 32. The pressing cylinder 31 is arranged at the bottom end of the base 1.

The shape of the tooling pressing head 32 matches the shape of the arc-shaped positioning seat 22.

[0035] See also Figure 6 and 7 , Figure 6 This is a first-angle view of the overall structure of a tooling pressure head according to an embodiment of the present invention. Figure 7 This is a second viewing angle diagram of the overall structure of a tooling pressure head according to an embodiment of the present invention.

[0036] The tooling pressure head 32 includes a pressing seat 321, two positioning members 322 and two pressing members 323.

The two pressing members 323 are respectively slidably arranged on the two sliding grooves, and the bottom ends of the two pressing members 323 are respectively connected to the two positioning members 322. After the pressing device 3 has been pressing the bent plate material for a long time, the top end of the pressing device 3 is prone to wear. The pressing member 323 can be disassembled from the sliding groove on the pressing seat 321 to ensure that the deformation of the pressing member 323 is within the standard range, thereby ensuring the processing yield of the bent plate material.

[0037] Preferably, the tooling press head 32 further includes two elastic members 324, and the bottom ends of the two pressing members 323 are provided with recessed portions, one end of the two elastic members 324 is respectively connected to the recessed portions of the two pressing members 323, and the other end of the two elastic members 324 is respectively connected to the two positioning members 322. In the initial state, under the extrusion of the two elastic members 324, the two pressing members 323 move closer to the axial direction of the tooling press head 32, so that the shape of the tooling press head 32 keeps matching with the shape of the arc-shaped positioning seat 22. In the pressing state, the tooling press head 32 presses the bent plate material, and the surface of the bent plate material may be uneven. The two pressing members 323 can slide on the slide groove of the pressing seat 321, so that the tooling press head 32 can achieve self-adaptation.
