[0003] A Chinese patent with publication number CN218828713U discloses a DC oil pump control cabinet that can realize stepless start and stop, including a switch cabinet body, a relay instrument room, a circuit breaker switch room and a busbar room. The setting of the hemispherical dust cover can filter the air to ensure the dustproof effect inside the switch cabinet body. Secondly, the dry porous cotton set inside the air inlet duct can dry the moisture in the air, so that the moisture in the air will not damage the electrical components inside the switch cabinet body.

[0004] When the DC oil pump control cabinet of the above patent is in use and dissipating heat, the air is extracted by the suction fan so that the air flows into the control cabinet comprehensively. The comprehensive entry of the air into the control cabinet will cause the gas to disperse. However, the electrical equipment and control components installed inside the control cabinet are unevenly distributed, and the flow direction of the gas flowing into the control cabinet cannot be uniformly adjusted, resulting in a reduced heat dissipation effect of the control cabinet. Summary of the invention

[0005] The object of the present invention is to provide a control cabinet for a modular bending machine electric hydraulic oil pump, which can meet the different requirements of electrical equipment and control elements being installed on the outside of the mounting frame, and the fan can slide longitudinally along the sliding rod to adjust the position of the fan so that the fan is aligned with the electrical equipment and control elements, and can guide the flowing gas so that the gas can be aligned with the heat dissipation position, thereby improving the heat dissipation effect and solving the problems raised in the above-mentioned background technology.

[0008] Preferably, an upper heat dissipation port is provided at the other end of the mounting frame, and the gas flowing into the interior of the housing from the upper heat dissipation port can pass through the electrical equipment and the control element and be discharged from the lower heat dissipation port.

[0009] Preferably, magnets are provided at the upper end of the fan and the lower end of the outer wall of the motor, and one of the fans is magnetically connected to a magnet on the surface of the motor corresponding to another fan through the magnet.

Figure 2 and Figure 3 As shown, the mounting frame 7 is fixed to the inside of the housing 1 by welding, and the electrical equipment and control components are pre-installed on the surface of the mounting frame 7 by bolts;

[0027] In addition, a lower heat dissipation port 5 is provided at one end of the mounting frame 7, and an upper heat dissipation port 3 is provided at the other end of the mounting frame 7. Figure 7 As shown, when heat is dissipated, the external gas flows into the housing 1 from the upper heat dissipation port 3, and the gas flowing into the housing 1 is discharged from the lower heat dissipation port 5;

[0028] In order to allow the flowing gas to accurately cool the electrical equipment and control components mounted on the surface of the mounting frame 7, as Figure 3 , Figure 6 and Figure 7 As shown, six pairs of sliding rods 6 are evenly distributed horizontally between the lower heat dissipation port 5 and the mounting frame 7, and seven fans 10 are evenly distributed vertically at one end of each pair of sliding rods 6. The fans 10 can slide along the sliding rods 6, and the positions of the fans 10 can be adjusted by sliding along the sliding rods 6. The adjustment of the positions of the fans 10 can cope with the electrical equipment and control components installed on the surface of the mounting frame 7, so that the gas discharged by the fans 10 can stably cool the electrical equipment and control components.

[0029] The fan 10 is provided with a sliding block 11 outside the sliding rod 6, and the inside of the sliding block 11 is slidably connected to the outside of the sliding rod 6. A connecting pipe 12 is provided on one side of one sliding block 11, and the connecting pipe 12 is welded and fixed to the sliding block 11.

[0032] Example 2

[0033] Six power posts 8 are evenly distributed horizontally between the mounting frame 7 and the sliding rod 6, and USB connectors 9 are distributed vertically on both sides of the six power posts 8. Figure 2 and Figure 5 As shown, the lower end of the fan 10 is provided with a motor 15 for output. The motor 15 can drive the fan 10 to start and extract the gas at the corresponding position through the output of the motor. One end of the motor 15 is connected to a USB terminal for power supply. After the USB terminal of the motor 15 is inserted into the USB connector 9, the power pole 8 will power the connected motor 15 after being energized. The upper end of each power pole 8 is independently provided with a power supply battery, and the power supply battery can independently power the power pole 8 and the corresponding connected motor 15.

[0034] Working principle: When the device is used and the electric hydraulic oil pump of the bending machine is controlled by the electrical equipment and the control element, the electrical equipment and the control element are installed in advance, and the bolts are passed through the electrical equipment and the control element and embedded in the mounting frame 7. After embedding, the electrical equipment and the control element are fixed. After fixing, the threaded rod 13 is rotated. The threaded rod 13 rotates in the connecting pipe 12 to drive the anti-skid sheet 16 to slide horizontally in the sliding block 11. After the anti-skid sheet 16 stops restricting the sliding rod 6, the sliding block 11 can slide longitudinally. The sliding block 11 drives the fan 10 connected at the rear end to slide longitudinally. The fan 10 is centered around the rotating shaft 18. The fan 10 is shaped to rotate at the front and rear ends outside the connecting strip 17, and the rotating fan 10 can be aligned with the electrical equipment and control components installed at the front end of the mounting frame 7. The power connection position at one end of the motor 15 is electrically connected to the USB connector 9 inside the power connection column 8 and then powered on. The power-on allows the blades inside the fan 10 to drive the air to flow, and the extracted air will flow into the shell 1 from the upper heat dissipation port 3, and the gas flowing into the shell 1 will be discharged from the lower heat dissipation port 5. The redundant and unused fans 10 are horizontally and parallelly distributed at the upper end of the sliding rod 6. When the fans 10 are horizontally distributed, two adjacent fans 10 are fixed by magnetic connection through magnets 14.
