[0002] A control cabinet is a device that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment. During normal operation, circuits can be connected or disconnected manually or automatically. In case of faults or abnormal operation, protective electrical appliances can disconnect the circuit or trigger an alarm. Measuring instruments can display various operating parameters, allow adjustment of certain electrical parameters, and provide alerts or signals for deviations from normal operating conditions. It is commonly used in power generation, distribution, and substations.

It also includes two independent cutting clamping cylinders and a cutting carriage control cylinder. This invention improves the cutting precision of the cutting machine, increases production efficiency, avoids product damage during the cutting process, reduces the generation of defective products, reduces the labor intensity of workers, and avoids secondary cutting of products.

[0004] Traditional control cabinets require a steel frame during production. However, the edges of the steel frame are covered with uniformly sized sheet metal. The processing and production of sheet metal for traditional control cabinets is inconvenient, which seriously affects the efficiency of the processing. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a control cabinet sheet metal cutting device, including a support mechanism 1. The support mechanism 1 includes two parallel bearing rails 11 placed on the ground. The side walls of the parallel bearing rails 11 are provided with sliding blocks 12. A sliding crossbar 13 is installed horizontally between the side walls of several sliding blocks 12. The top four corners of the sliding crossbar 13 are provided with buffer pads 14. The top four corners of the buffer pads 14 are provided with access bases 15. The top center of the access base 15 is provided with an upper frame 16.

[0027] In this embodiment: a connecting seat 17 is provided at the top center of the parallel bearing track 11, a fixed bearing 18 is provided at the top center of the connecting seat 17, a drive screw 19 is horizontally mounted at the center of the fixed bearing 18, and a synchronous motor 191 is provided at the bottom center of the drive screw 19.

[0028] The purpose of using the connecting seat 17 and the fixed bearing 18 is to avoid damping obstruction when the lead screw 19 rotates.

[0029] In this embodiment: the output end of the synchronous motor 191 is connected to one end of the corresponding drive screw 19, and the side wall of the sliding crossbar 13 is provided with a positioning sliding mechanism 2;

[0030] The positioning sliding mechanism 2 includes a linear push support rod 21 located at the end of the sliding crossbar 13. The side wall of the linear push support rod 21 is provided with a sliding frame 22 for pushing, and the middle part of the sliding frame 22 is provided with a concave frame 23 for fitting.

[0031] The purpose of using the sliding frame 22 and the corresponding concave frame 23 is to drive the corresponding sliding frame 22 to move, and further complete the displacement of the corresponding cutting iron sheet.

[0032] In this embodiment: the two ends of the sliding frame 22 are respectively connected to the side wall of the synchronous motor 191 through connecting rods, and the top center of the upper frame 16 is provided with a pressing and cutting mechanism 3.

[0033] The synchronous motor 191 drives the cutting mechanism 3 to move.

[0034] In this embodiment: the pressing and cutting mechanism 3 includes a push frame 31 disposed at the top center of the access base 15. The inner sidewall of the push frame 31 is provided with adjustment slots 32 for opening. A push rail 33 is arranged horizontally between the two adjustment slots 32. A horizontal bearing rod 34 is installed horizontally between the sidewalls of the push rail 33. A synchronous stepper motor 36 is provided on both sides of the bottom of the positioning rod of the horizontal bearing rod 34. A lead screw 37 is driven at the output end of the synchronous stepper motor 36.

[0035] The synchronous stepper motor 36 is used to drive the lead screw 37 to rotate after the synchronous motor 191 is energized.

[0036] In this embodiment: the lead screw 37 has two halves, with a bearing 38 in the middle to offset the torque in situ. The bottom two sides of the transverse bearing rod 34 are respectively provided with transmission lead screws 39. The surface of the rod body of the transmission lead screw 39 is fitted with a lifting sleeve 391. A cutter frame 392 is installed transversely between the two lifting sleeves 391. Lifting rods 393 are machined on both sides of the cutter frame 392. The surface of the lifting rod 393 is fitted with a buffer spring 394. The top of the rod body of the lifting rod 393 is provided with a trigger cylinder 395. The bottom of the trigger cylinder 395 is provided with a cutter 396.

[0037] The specified iron sheet is cut by pressing down on the cutter 396.

[0038] In practical use, the outer sheet metal of the control cabinet that needs to be cut is first placed directly on the sliding frame 22. The sheet metal is fixed by the support and clamping of the concave frame 23. After the synchronous motor 191 is powered on, the linear displacement is achieved along the surface of the drive screw 19 during the rotation of the motor, which in turn drives the slider on the sliding frame 22 to achieve linear displacement.

[0039] At this point, the patch is transferred to the cutting mechanism 3. The synchronous stepper motors 36 on both sides rotate, driving the corresponding lead screw 37 to rotate. During the rotation, the corresponding transverse support rod 34 is displaced back and forth. During the displacement, the distance between the cutters 396 is adjusted by sliding back and forth on the groove surface of the push track 33. After the distance is shortened and the appropriate patch width is focused, the rotation of the corresponding transmission lead screw 39 is directly controlled to adjust the lifting displacement of the lifting sleeve 391. During the displacement, the cylinder of the trigger cylinder 395 moves downward. Finally, the surface of the buffer spring 394 is pressed to trigger the cutter 396 to contact the iron sheet to be cut, thus cutting off the excess patch and promoting the fitting and assembly of the patch structure with the appropriate size and volume. The buffer spring 394 then returns to its original position.
