Description

Technical Field

[0001] This invention relates to the field of milling technology, and in particular to an array milling forming device for heat dissipation fins of a power distribution cabinet. Background Technology

[0002] The reason why milling is used instead of chamfering for half of the heat dissipation fins of the distribution box is that milling can perfectly meet the stringent requirements of avoiding complex irregular structures, precise chamfering to prevent high-voltage electrical discharge, and high flatness fit. These are precisely the requirements that chamfering, which can only process a single plane, cannot achieve. The edges of the milled heat dissipation fins also need to be chamfered to eliminate electrical safety hazards and improve overall performance. In the existing technology, the milling and chamfering of heat dissipation fins are usually divided into two independent processing steps, which not only increases the number of clamping and production costs, but also few machines can complete the chamfering at the same time as milling. More importantly, the existing process lacks a flexible mechanism to adaptively adjust the chamfering tilt angle according to the fin thickness, making it difficult to achieve precise and differentiated chamfering for fins with different wall thicknesses in a single process.

[0014] The array milling forming device for heat dissipation fins of a power distribution cabinet provided by the present invention has the following advantages: 1. By coordinating the secondary cutter adjustment mechanism and the secondary cutter control mechanism, the tilt angle of the secondary milling cutter head is adjusted, which enables the chamfer angle to be adjusted as needed when milling heat dissipation fins with different fin thicknesses. This achieves adaptive matching of the optimal chamfer tilt angle according to different fin thicknesses, thereby completing milling and precise chamfering simultaneously in a single machining process.

[0015] 2. Through the coordination of the secondary tool adjustment mechanism, the secondary tool control mechanism and the adjustment mechanism, the cutting angle can be adjusted synchronously when the tilt angle is adjusted. By optimizing the cutting path and stress state, the surface finish of the machined surface can be greatly improved and the tool life can be extended, while ensuring the accurate forming of the chamfer profile of fins of different thicknesses.

[0016] 3. By adjusting the tilt angle and entry angle of the sub-milling cutter head through the sub-cutter control mechanism, the height of the sub-milling cutter head is adjusted simultaneously. This avoids height mismatch when adjusting the entry angle of the sub-milling cutter head, which could lead to ineffective or excessive cutting. This ensures the accuracy of the chamfer profile, optimizes the stress state, and extends the service life of the sub-milling cutter head.

[0017] 4. The secondary cutter control mechanism enables the simultaneous adjustment of the distance between the secondary cutter head and the center point of the groove milled by the main cutter when adjusting the entry angle of the secondary cutter head. This ensures effective milling and avoids damage to the secondary cutter heads caused by the lower ends of the two secondary cutter heads touching each other during adjustment.

[0018] 5. The coordination between the adjustment mechanism and the water spray mechanism increases the water output when the inclination angle of the secondary milling cutter head is increased, thereby enhancing the heat dissipation and cooling effect, preventing the secondary milling cutter head from annealing, improving lubrication conditions, reducing cutting resistance, and enhancing rinsing capacity to ensure the smoothness of the chamfered surface.

[0032] In this embodiment, the water spraying mechanism 4 includes a four-way valve housing 41, a four-way valve core 42 is rotatably connected inside the four-way valve housing 41, a pulley 43 is fixedly connected to the upper end of the four-way valve core 42, a pulley 45 is connected to the pulley 43 via a transmission belt 44, the middle of the pulley 45 is fixedly connected to the upper end of the transmission shaft 35, a main spray pipe 46 is fixedly connected to the front opening of the four-way valve housing 41, and auxiliary spray pipes 47 are fixedly connected to the openings on both sides of the four-way valve housing 41.

[0033] In this embodiment, the lower end of the four-way valve housing 41 is fixedly connected to the upper end of the limiting housing 11. The lower end of the main nozzle 46 penetrates the front side of the upper end of the limiting housing 11 and extends to the front side of the main milling cutter 5. The lower ends of the auxiliary nozzles 47 penetrate both sides of the upper end of the limiting housing 11 and extend to the side of the lower end of the auxiliary milling cutter 6 away from the center of the toothed ring 26.

[0034] Working principle: When it is necessary to adjust the secondary milling cutter 6 to chamfer the upper edge of the heat sink fins at a larger tilt angle, the rotary seat 18 is rotated. Through the cooperation of the adjusting column 19 and the arc groove 16, the lifting seat 14 is driven to descend. This, through the cooperation of the toothed groove 17 and the half gear 212, drives the secondary milling cutter 6 inside the secondary cutter holder 21 to adjust its tilt angle. Through the cooperation of the secondary cutter adjustment mechanism 1 and the secondary cutter control mechanism 2, the tilt angle of the secondary milling cutter 6 is adjusted. This allows for the adjustment of the chamfer angle as needed when milling heat sink fins of different thicknesses. It achieves adaptive matching of the optimal chamfer tilt angle according to different fin thicknesses, thus simultaneously completing milling and precise chamfering in a single machining process. This effectively solves the problem of the separation of traditional processes and the lack of precision. To address the challenge of flexible adaptation, when adjusting the tilt angle of the secondary milling cutter 6, the three-pronged gear 31, through its engagement with the tooth groove 2 110, drives the transmission shaft 1 32 to rotate. This, in turn, drives the bevel gear 2 34 to rotate via the bevel gear 1 33, which in turn drives the five-pronged gear 37 via the transmission shaft 2 35 and the four-pronged gear 36. Simultaneously, the five-pronged gear 37 drives the six-pronged gear 38 to rotate in the opposite direction. Furthermore, the adjusting rod 39 and the adjusting plate 310 simultaneously rotate the height adjusting seats 22 on both sides backward, ultimately causing the secondary milling cutter 6 on both sides to rotate backward, finely adjusting the entry angle of the secondary milling cutter 6. Through the cooperation of the secondary cutter adjustment mechanism 1, the secondary cutter control mechanism 2, and the adjustment mechanism 3, the entry angle can be synchronously adjusted when the tilt angle changes, optimizing the cutting path and stress state. While significantly improving the surface finish and extending tool life, it ensures precise chamfering of fins of different thicknesses. When adjusting the entry angle of the sub-milling cutter 6, the full gear 25 rotates inside the gear ring 26, driving the threaded rod 23 to rotate via the telescopic rod 24. This, in turn, lowers the sub-milling cutter 6 via the height adjustment seat 22, finely adjusting its height. The sub-cutter control mechanism 2 simultaneously adjusts the height of the sub-milling cutter 6 when adjusting its tilt angle and entry angle, preventing height mismatch during entry angle adjustments that could lead to ineffective or excessive cutting. This ensures the accuracy of the chamfering profile, optimizes the stress state, and extends the service life of the sub-milling cutter 6. When the cutter head 6 is adjusted to its entry angle, the telescopic rod 210 rotates simultaneously through the engagement of the gear 211 and the gear ring 26. This, in turn, drives the telescopic rod 28 to rotate via the universal coupling 29. Furthermore, the threaded seat 213 and the connecting column 214 extend the lower end of the sub-end milling cutter head 6. When the inclination angle is larger, the lower end of the sub-end milling cutter head 6 is closer to the center point of the groove milled by the main end milling cutter 5; conversely, when the inclination angle is smaller, the lower end of the sub-end milling cutter head 6 is farther from the center point of the groove milled by the main end milling cutter 5. The sub-end milling control mechanism 2 simultaneously adjusts the distance between the sub-end milling cutter head 6 and the center point of the groove milled by the main end milling cutter 5 while adjusting the entry angle of the sub-end milling cutter head 6. This ensures effective milling while preventing the lower ends of the two sub-end milling cutter heads 6 from touching during adjustment.Damage to the sub-end mill cutter 6 head is caused by the following: When adjusting the cutting angle of the sub-end mill cutter 6 head, the transmission shaft 2 35 synchronously drives the pulley 2 45 to rotate, which in turn drives the pulley 1 43 to rotate via the transmission belt 44. This, in turn, drives the four-way valve core 42 to rotate inside the four-way valve housing 41. This results in a larger overlap between the water outlets at both ends of the four-way valve housing 41 and the water outlets on both sides of the four-way valve core 42 as the inclination angle of the sub-end mill cutter 6 head increases. Consequently, the water spray volume from the secondary nozzle 47 increases with the inclination angle of the sub-end mill cutter 6 head. Through the coordination of the adjustment mechanism 3 and the water spraying mechanism 4, the water output is increased when the inclination angle of the sub-end mill cutter 6 head is increased, enhancing the heat dissipation and cooling effect, preventing annealing of the sub-end mill cutter 6 head, improving lubrication conditions, reducing cutting resistance, and enhancing rinsing capacity, thus ensuring the smoothness of the chamfered surface.
