[0026] See also Figure 1 and Figure 3The main body 10 of the press brake includes a frame 110, a lifting assembly 120, a press seat 130 and a press head 140. The press seat 130 is located above the workbench of the frame 110, the lifting assembly 120 is installed above the frame 110, the press head 140 is located above the press seat 130, and the lifting assembly 120 drives the press head 140 to move in the vertical direction and press on the press seat 130. Two sets of adjustment mechanisms 20 are respectively arranged on both sides of the press seat 130, and the adjustment mechanism 20 includes a lower rod 210, an upper rod 220 and a height adjustment part 230. The top end of the upper rod 220 is rotatably arranged with the middle part of the end face of the press seat 130, the bottom end of the lower rod 210 is fixedly arranged with the frame 110, and the height adjustment part 230 connects the top end of the lower rod 210 and the bottom end of the upper rod 220.

[0027] The press seat 130 in the press brake is a rectangular parallelepiped structure, and the four sides of the press seat 130 are respectively set with bending grooves of different angle structures. The aluminum alloy plate is placed above the press seat 130 on the workbench in advance, and the lifting assembly 120 drives the press head 140 to move downward, and the press head 140 punches the aluminum alloy plate above the press seat 130 to achieve the bending process of the aluminum alloy plate. When it is necessary to replace the press seat 130 on different sides, the operator only needs to adjust the adjustment mechanism 20 on both sides of the press seat 130, that is, adjust the upper rod 220 through the height adjustment part 230 to drive the press seat 130 to rise, until the press seat 130 with a rectangular parallelepiped structure can be rotated between the two groups of adjustment mechanisms 20, and after the press seat 130 is rotated to the desired side facing up, the upper rod 220 is adjusted to move downward through the height adjustment part 230 until the press seat 130 is tightened and fixed above the workbench. That is, the press brake can realize the easy replacement and adjustment of the press seat 130 by a single person.

[0028] For specific settings, see Figure 1 The hydraulic cylinder 121, the connecting seat 122, and the support rod 123 in the two sets of lifting components 120 are respectively arranged on both sides of the frame 110. The lifting component 120 includes a hydraulic cylinder 121, a connecting seat 122, and a support rod 123. The bottom end of the support rod 123 is fixed to the top of the pressure head 140, the connecting seat 122 is rotatably arranged on the top of the frame 110, one end of the connecting seat 122 is rotatably connected to the top of the support rod 123, the bottom of the hydraulic cylinder 121 is rotatably installed with the frame 110, and the output rod end of the hydraulic cylinder 121 is rotatably connected to the end of the connecting seat 122 away from the support rod 123.

[0029] When the output rod end of the hydraulic cylinder 121 extends outward, the output rod end of the hydraulic cylinder 121 pushes the connecting seat 122 to rotate, and the rotating connecting seat 122 pushes the support rod 123 to drive the pressing head 140 to move downward for stamping. When the output rod end of the hydraulic cylinder 121 is recovered, the hydraulic cylinder 121 finally drives the pressing head 140 to move upward and reset.

[0030] In the above specific implementation, please refer to Figure 3 and Figure 4The height adjustment part 230 includes a first threaded rod 231 and a second threaded rod 232.

[0031] The rotating nut 233 drives the first threaded rod 231 and the second threaded rod 232 to rotate at the same time. The rotating first threaded rod 231 and the second threaded rod 232 respectively drive the upper rod 220 and the lower rod 210 to move away from or towards each other, thereby adjusting the height of the pressure seat 130.

[0032] Furthermore, both the upper rod 220 and the lower rod 210 are L-shaped structures, the upper rod 220 is provided with an insertion rod 250 at the top, and the middle of the end surface of the pressure seat 130 is provided with a socket 150, and the insertion rod 250 is inserted into the socket 150 for rotational cooperation. The arrangement of the socket 150 and the insertion rod 250 enables relative rotation adjustment between the pressure seat 130 and the upper rod 220. The lower rod 210 is provided with a fixing block 240 at the bottom, and the fixing block 240 is fixed to the frame 110 by fixing bolts 260.

[0033] It should be noted that the specific model and specifications of the hydraulic cylinder 121 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
