Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, in particular to a cutting device for processing a bus duct shell. Background Art

[0002] The busbar housing is typically a long, U-shaped structure with several heat dissipation fins distributed evenly along its length in the middle. As a crucial component of power transmission equipment, the busbar housing's manufacturing process typically involves key steps such as forming and cutting sheet metal.

[0003] In the busbar trunking shell processing process, a cutting device is a key piece of equipment for achieving precise segmentation of the shell along its length or width. This device typically consists of a workbench, a clamping mechanism for positioning and holding the shell, a cutting mechanism for slicing the shell, and a drive component. After the clamping mechanism secures the shell, the cutting mechanism performs the cutting operation, completing the segmented processing.

[0004] During the cutting process, a large amount of metal debris (including flaky chips, powdered chips, and rolled chips) is generated in the contact area between the saw blade and the busbar housing. Under the dual influence of the cutting impact and its own gravity, these chips will accumulate more in the area closest to the cutting section, while only a small amount of chips will be scattered in the area farther away from the section.

[0005] In the waste chip cleaning process, the existing technology generally uses a continuous airflow along the length of the shell for blowing, pushing the waste chips toward the cut section of the shell. However, in actual operation, as the pushing process continues, the waste chips near the cross section will continue to gather in front of the airflow, forming a "the more you push, the denser" accumulation state, and then embedding into the fin gap. Because the intensity of the blowing airflow is fixed, it is difficult to form an effective impact force on the waste chips stuck in the fin gap, resulting in such residues cannot be completely blown out, and the cleaning effect is less than ideal. To this end, we propose a cutting device for bus duct shell processing to effectively solve the above-mentioned drawbacks. Summary of the Invention

[0013] Before cutting, the length direction of the bus duct shell is parallel to the length direction of the workbench;

[0014] After cutting, the two bus duct shells move away from each other. When the length direction of the bus duct shell remains parallel to the length direction of the workbench, the lateral nozzles work to spray air toward the surface of the bus duct shell; when the length direction of the bus duct shell remains perpendicular to the length direction of the workbench, the axial nozzles work to spray air toward the surface of the bus duct shell.

[0026] Compared with the prior art, the present invention provides a cutting device for processing bus duct shells, which has the following beneficial effects:

[0027] 1. This invention utilizes a sliding seat, a rotating seat, and an air blowpipe. When the two busbar duct housings move away from each other with the sliding seat, multiple lateral nozzles activate, gathering debris from the busbar duct housing surfaces toward the cut surface. After the rotating seat rotates the busbar duct housing 90°, a single axial nozzle activates, coordinating with the movement of the busbar duct housing to spray point-by-point into the fin gaps, effectively impacting debris trapped within the gaps and ultimately completely removing them.

[0028] 2. The rotary drive mechanism of the present invention is coordinated with the worm gear, worm, gear and rack. When the sliding seat moves to the preset position along the workbench, it drives the rotating seat to automatically complete the 90° flip of the bus duct shell; at the same time, the meshing characteristics of the worm gear and worm have a self-locking function, which can form a reliable lock when the rotating seat is in the initial position or rotated into place, avoiding accidental rotation of the rotating seat due to external force or vibration, and ensuring that the bus duct shell always maintains a stable posture during the cutting or cleaning process.

[0029] 3. The present invention cooperates with the first solenoid valve, the second solenoid valve, the first pressure sensor, and the second pressure sensor, and utilizes the position change of the rotating seat itself to directly drive the nozzle switching, which has a faster response and is not easily interfered with, ensuring that the lateral / axial nozzle is accurately started in the corresponding posture of the busbar duct shell, greatly improving the degree of automation of the cleaning operation.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figures 1 to 8 A cutting device for processing a busbar trunking shell includes a workbench 1 extending in a horizontal direction. A main controller is installed on the workbench 1, which uses a PLC programmable logic control system as a core control unit and can control various actuators in the device.

[0041] This embodiment also includes: a support frame 2, a cutting mechanism 3, two sliding seats 4, two rotating seats 6 and two blowing pipes 9, which are used to solve the problem in the prior art that waste chips continue to accumulate near the cutting section and embed into the fin gap.

[0042] Among them, the support frame 2 is fixed to the top of the workbench 1 to provide support for other components in the device. The cutting mechanism 3 is installed on the support frame 2 and suspended above the middle of the workbench 1. The cutting mechanism 3 is electrically connected to the main controller, and the cutting mechanism 3 is controlled by the main controller. Specifically, the cutting mechanism 3 includes an electric telescopic rod 301 installed on the top of the support frame 2, and a cutting machine 302 suspended above the middle of the workbench 1 is connected to the execution end of the electric telescopic rod 301; the electric telescopic rod 301 and the cutting machine 302 are respectively connected to the main controller for communication. During operation, the main controller sends a displacement instruction to the electric telescopic rod 301 according to the preset cutting parameters, drives the cutting machine 302 to move downward along the Z-axis direction, and cooperates with the cutting machine 302 to cut the bus duct shell.

[0043] Secondly, two sliding seats 4 are symmetrically distributed on either side of the center of the workbench 1. The two sliding seats 4 can move closer to or farther from each other along the length of the workbench 1. A rotating shaft 5 is rotatably connected to the top of each sliding seat 4. In this embodiment, a linear module 12 corresponding to each sliding seat 4 is mounted on the top of the workbench 1. Each sliding seat 4 is fixed to the actuator end of the corresponding linear module 12. Each linear module 12 is separately connected to the main controller, thereby driving the two sliding seats 4 to move closer to or farther from each other.

[0044] In addition, the two rotating seats 6 correspond one-to-one with the two rotating shafts 5, and each rotating seat 6 is fixed to the top of the corresponding rotating shaft 5. A clamp 7 for clamping the bus duct housing is provided on the top of each sliding seat 4. A rotation drive mechanism 8 is provided on each sliding seat 4 for rotating the rotating seat 6 along the rotating shaft 5 to make the bus duct housing parallel to the length direction of the workbench 1 or perpendicular to the length direction of the workbench 1.

[0045] The two blowing pipes 9 are respectively fixed to both sides of the support frame 2 and extend along the width direction of the workbench 1. A plurality of lateral nozzles 10 are evenly distributed along the axial direction on the side wall of each blowing pipe 9, and an axial nozzle 11 is provided at one end of each blowing pipe 9.

[0046] Before cutting, the bus duct shell is positioned and clamped by the clamp 7 , and the length direction of the bus duct shell is parallel to the length direction of the workbench 1 , so the bus duct shell can be cut using the cutting mechanism 3 .

[0047] After cutting, the two busbar trunking shells move away from each other. When the length of the busbar trunking shell remains parallel to the length of the workbench 1, the lateral nozzles 10 work to spray air toward the surface of the busbar trunking shell, pushing the waste chips on the surface of the busbar trunking shell along the length direction toward the cut surface, facilitating their collection at the cut surface. When the length of the busbar trunking shell remains perpendicular to the length of the workbench 1, the axial nozzles 11 work to spray air toward the surface of the busbar trunking shell, coordinating with the movement of the busbar trunking shell to achieve point-by-point spraying of the fin gaps. The airflow creates a localized high pressure in the gap, effectively impacting the tiny waste chips stuck in the gap, and increasing the waste chip removal rate in the gap to over 99%.

[0048] With this design, during the initial cleaning phase (when the busbar housing is parallel to the length of the workbench 1), the dispersed airflow from multiple lateral nozzles 10 is suitable for cleaning a large area, ensuring the orderly migration of debris. In the later stages of cleaning (when the busbar housing is perpendicular to the length of the workbench 1), the airflow is switched to a single axial nozzle 11, shifting from dispersed to concentrated. At the same air source pressure, the outlet flow rate of the axial nozzle 11 increases by approximately 60%, resulting in more concentrated pressure, which can overcome the airflow resistance in the fin gaps and solve the problem of cleaning fine gaps.

[0049] The rotating mechanism 8 is introduced below:

[0050] The rotary drive mechanism 8 comprises a mounting housing 801 fixed to the bottom of the sliding seat 4. A worm gear 802, located within the mounting housing 801, is secured to the lower end of the rotating shaft 5. A worm 803, engaged with the worm gear 802, is rotatably connected within the mounting housing 801. The axial direction of the worm gear 803 is parallel to the width of the worktable 1. When the worm gear 803 rotates, the meshing teeth of the worm gear 802 drive the synchronous rotation of the worm gear 802, thereby driving the rotating seat 6 to rotate along with the rotating shaft 5.

[0051] The two ends of the worm 803 extend outside the mounting housing 801. Gears 804 are fixed at both ends of the worm 803. Racks 805 corresponding to the gears 804 are fixed on the top of the workbench 1. When the gears 804 are engaged with the racks 805, the worm 803 is driven to rotate.

[0052] With this design, after cutting is complete, the main controller instructs the linear module 12 to drive the sliding seat 4 in a diverging motion along the length of the worktable 1. Initially, the gear 804 and rack 805 are separated, and the busbar housing remains parallel to the length of the worktable 1. Later in the motion, the gear 804 gradually meshes with the rack 805, driving the worm 803 to rotate synchronously. The meshing of the worm's teeth drives the worm wheel 802 and the rotating shaft 5, ultimately driving the rotating seat 6 and the clamped busbar housing to gradually rotate.

[0053] When the sliding seat 4 moves to the preset position, the busbar housing completes a 90° rotation, and its longitudinal direction changes from parallel to the workbench 1 to perpendicular. During this process, the reverse self-locking characteristics of the worm gear 802 and worm 803 provide a reliable mechanical lock, allowing the rotating seat 6 to maintain a stable posture even when subjected to radial external forces or equipment vibration.

[0054] This design eliminates the need for an additional rotary drive motor, achieving rotational motion synchronously with the movement of the sliding seat 4. Furthermore, the meshing characteristics of the worm wheel 802 and the worm 803 provide a self-locking function, reliably locking the rotating seat 6 in its initial position or after it has been fully rotated. This prevents accidental rotation of the rotating seat 6 due to external forces or vibration, ensuring that the busbar duct housing remains stable during cutting or cleaning.

[0055] It's worth noting that an inner tube is axially fixed inside the blowpipe 9, with an annular gap between the inner tube and the blowpipe 9. The lateral nozzle 10 communicates with the annular gap, while the axial nozzle 11 communicates with the inner tube. This nested structure creates independent pathways for the lateral and axial airflows, preventing mutual interference and ensuring the stability of both purge modes.

[0056] Specifically, a first air inlet pipe 13, communicating with the annular gap, is fixed to the air blowing pipe 9. A first solenoid valve 14 is installed on this first air inlet pipe 13 to control the air flow to and from the lateral nozzle 10. A second air inlet pipe 15, communicating with the inner tube, is fixed to the air blowing pipe 9. Both the second air inlet pipe 15 and the first air inlet pipe 13 are connected to an external air source via pipes. A second solenoid valve 16 is installed on this second air inlet pipe 15 to control the air flow to and from the axial nozzle 11. Both the first and second solenoid valves 14, 16 are connected to a main controller.

[0057] With this design, the main controller controls the first and second solenoid valves 14, 16 to automatically switch between the lateral nozzles 10 and the axial nozzles 11. Specifically, when multiple lateral nozzles 10 are in operation, a larger purge area can be formed. Combined with the movement of the sliding seat 4, waste chips on the surface of the busbar duct shell can be gathered toward the cut surface.

[0058] When switching to the axial nozzle 11, the main controller closes the first solenoid valve 14 and opens the second solenoid valve 16. The entire flow of the external air source is concentrated and delivered to the single axial nozzle 11 through the inner tube. The convergence of the airflow increases the outlet pressure by 40% to 60%, forming a high-intensity airflow. For the fin gaps of the busbar housing, the high-speed airflow can break through air resistance and create an instantaneous impact force, completely removing stubborn debris such as slag and burrs stuck in the gaps (the removal rate is increased to 99%). This solves the problem that the side nozzle 10 has difficulty reaching deep gaps due to the dispersed airflow.

[0059] This on-demand switching blowing mode not only achieves large-area rapid slag removal through the lateral nozzle 10, shortening the time of single cleaning, but also enhances the cleaning ability through the concentrated airflow of the axial nozzle 11, meeting the full process requirements of the bus duct shell from rough cleaning to fine cleaning.

[0060] In another embodiment of the present application, a curved clearance hole 17 is formed through the sliding seat 4, and a contact plate 18 is fixed to the bottom of the rotating seat 6 and extends into the curved clearance hole 17. When the rotating seat 6 rotates about the rotation axis 5, the contact plate 18 moves along the curved clearance hole 17 in a synchronous trajectory, thus achieving the dual functions of mechanical limit and signal triggering.

[0061] A first pressure sensor 19 is installed at one end of the arc-shaped clearance hole 17, and a second pressure sensor 20 is installed at the other end of the arc-shaped clearance hole 17; the first pressure sensor 19 and the second pressure sensor 20 are respectively connected to the main controller for communication.

[0062] With the above design, when the bus duct shell is in the initial non-rotated state, the touch plate 18 maintains stable contact with the first pressure sensor 19, and the sensor transmits a continuous pressure signal to the main controller. The main controller instructs the first solenoid valve 14 to open, so that the side nozzle 10 quickly enters the working state, thereby achieving large-scale blowing of the bus duct shell surface.

[0063] When the rotating seat 6 starts to rotate, the touch plate 18 disengages from the first pressure sensor 19, the sensor pressure signal disappears, the main controller cuts off the power supply to the first solenoid valve 14, and the side nozzle 10 stops spraying immediately, effectively avoiding the splashing of waste chips caused by the disorder of airflow direction during rotation.

[0064] When the rotating seat 6 completes a 90-degree rotation and reaches its proper position, the contact plate 18 presses against the second pressure sensor 20. This sensor trigger signal is transmitted to the main controller, opening the second solenoid valve 16. This ensures that the axial nozzle 11 is activated only after the busbar housing has stabilized, creating a concentrated airflow impact. This design, by directly linking the rotational motion with the sensor signal, enables fully automatic switching between purge modes, ensuring that the lateral / axial nozzles are precisely activated in the corresponding busbar housing posture, significantly enhancing the automation of the cleaning operation.

[0065] Furthermore, the outlet of the side nozzle 10 is fan-shaped and flat, and the side nozzle 10 is tilted toward the center of the workbench 1. This structure creates a wide, flat airflow after the compressed air is ejected. Combined with the tilted arrangement, it can precisely cover the surface of the busbar duct shell. At the same time, the fan-shaped airflow maintains a uniform pressure distribution during the diffusion process, pushing the flaky and granular waste scattered on the surface of the busbar duct shell in the direction of the cut surface.

[0066] The outlet of the axial nozzle 11 is tapered and angled toward the edge of the worktable 1. This conical convergence creates a focused airflow before it is ejected, increasing the airflow velocity by 60% compared to the lateral nozzle 10. This is sufficient to penetrate the gaps between the fins of the busbar duct housing and effectively impact small debris trapped within these gaps. Combined with the tilted arrangement, the high-pressure airflow is directed toward the chip collection chute at the edge of the worktable.

[0067] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
