Description

Technical Field

[0001] The utility model relates to the field of arc extinguishing hood forming machines, in particular to an arc extinguishing hood forming machine. Background Art

[0002] Arc extinguishing hoods are commonly used to bring an arc into contact with a solid dielectric, reducing its temperature and accelerating its extinction. When the current is interrupted, the arc generates high temperatures and intense light, posing a significant threat to equipment and personnel safety. By bringing the arc into contact with a solid dielectric, the arc extinguishing hood utilizes the dielectric's cooling and heat dissipation properties to rapidly reduce the arc's temperature, thereby accelerating its extinction. This device is widely used in power engineering, particularly in applications requiring rapid current interruption, such as circuit breakers and contactors. Arc extinguishing hood manufacturing involves stamping and forming.

[0003] Existing arc extinguishing cover forming machines, for example, the arc extinguishing grid punching device for air switches proposed in patent application number "CN202321693635.5", uses a mold, mounting plate, turntable, connecting rod, stamping hammer and other structures. The motor drives the turntable to rotate, so that the turntable drives the connecting rod to rotate, so that the connecting rod squeezes the stamping column and moves downward inside the support column, driving the stamping hammer connected to it to press into the stamping groove in the mold, so that the stamping part is formed. At the same time, the cutter driven by the stamping hammer cooperates with the use of the incision to cut off the stamped part after stamping, so that the stamping part is directly stamped and formed.

[0004] However, the existing technology has defects. During the stamping process, debris will be generated. The accumulation of debris will interfere with the arc chute, resulting in small pits on the stamping surface of the arc chute, resulting in poor surface smoothness of the formed part, affecting the molding quality of the arc chute. Therefore, an arc chute molding machine is proposed. Utility Model Content

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0023] An arc extinguishing hood forming machine, such as Figures 1-4 As shown, it includes a base 1, the upper end of the base 1 is fixedly connected to an arm 2, the arm 2 is fixedly connected to a stamping cylinder 3, the output end of the stamping cylinder 3 is fixedly connected to an upper die 4, the upper end of the base 1 is fixedly connected to a lower die 5, the lower end of the upper die 4 is fixedly connected to a stamping die 9, a stamping cavity 10 is opened in the middle of the upper die 4, the stamping die 9 is stamped and matched with the stamping cavity 10, a blanking component for discharging arc extinguishing cover molded parts is fixedly connected to the inside of the lower die 5, a punching component for punching holes in the arc extinguishing cover is fixedly connected to the stamping cylinder 3, and a cleaning component for cleaning the upper end of the lower die 5 is fixedly connected to one side of the arm 2.

[0024] The base 1 and the arm 2 form a frame, and the workpiece is placed on the upper end of the stamping cavity 10. The upper die 4 is controlled by the stamping cylinder 3 (model TN16X20S) to stamp the lower die 5, so that the stamping die 9 stamps the stamping cavity 10, and the arc extinguishing hood is stamped and formed. At this time, the upper die 4 and the lower die 5 are not separated, and the punching assembly is running to punch the formed arc extinguishing hood. The upper die 4 and the lower die 5 are separated, and the blanking assembly is compressed during stamping and reset after the stamping is completed, pushing the arc extinguishing hood to be demoulded, which is convenient for the arc extinguishing hood to be discharged. After the arc extinguishing hood is taken out, the cleaning assembly is run to clean the debris on the upper end of the lower die 5 to prevent the debris from affecting the molding quality of the arc extinguishing hood.

[0025] like Figures 1-4As shown, the blanking assembly includes a spring 14, and there are multiple groups of springs 14. The multiple groups of springs 14 are all fixed to the inside of the lower die 5. The upper ends of the multiple groups of springs 14 are commonly fixed with a slide plate 13, and the slide plate 13 is slidably connected to the inside of the lower die 5. The upper end of the slide plate 13 is fixed with a slider 11, and the slider 11 is slidably inserted into the stamping cavity 10.

[0026] During stamping, the stamping die 9 squeezes the slider 11 through the stamping cavity 10, causing the slide plate 13 to squeeze the spring 14. The compressed elastic potential energy of the spring 14 increases. When the upper die 4 and the lower die 5 are separated, the stamping die 9 and the stamping cavity 10 are separated, and the spring 14 squeezes the slider 11 through the slide plate 13, causing the slider 11 to push the formed arc extinguishing cover upward in the forming cavity, making it easier to unload the arc extinguishing cover.

[0027] like Figure 1 、 Figure 2 、 Figure 4 As shown, the punching assembly includes a punching cylinder 6, which is fixed to the punching cylinder 3, and a sliding plate 7 is fixed to the output end of the punching cylinder 6. The sliding plate 7 is slidingly connected to the output end of the punching cylinder 3, and a punching knife 8 is fixed to the lower end of the sliding plate 7. The punching knife 8 is slidingly connected to the punching die 9. A punching groove 12 is opened on the slider 11, and the punching groove 12 passes through the slide plate 13. The punching knife 8 is plugged into the punching groove 12, and a collecting groove 16 is clamped at the position corresponding to the lower end of the punching groove 12 inside the lower die 5.

[0028] The structures including the punching die 9, the punching cavity 10 and the punching knife 8 are customized according to the arc extinguishing cover. After the punching cylinder 3 controls the upper die 4 and the lower die 5 to punch, the punching cylinder 6 (model TN10-30) controls the sliding plate 7 to slide, so that the sliding plate 7 drives the punching knife 8 to punch holes in the arc extinguishing cover. The end of the punching knife 8 is inserted into the punching groove 12, and the waste removed by punching falls into the collection groove 16.

[0029] like Figure 2 As shown, the inner wall of the lower die 5 is fixed with a limit block 15 , the slide plate 13 is located between the limit block 15 and the upper end of the upper die 4 , and the lower end of the slide plate 13 is in abutment with the upper end of the slider 11 .

[0030] The limit block 15 limits the lowest height to which the slide plate 13 can slide, thereby preventing the slide plate 13 from excessively squeezing the spring 14 and causing elastic fatigue of the spring 14 .

[0031] like Figure 1 、 Figure 2 As shown, the cleaning assembly includes an upper frame 18 and a lower frame 17, both of which are fixedly connected to one side of the machine arm 2. The lower end of the upper frame 18 is fixedly connected to a servo motor 19, and the output end of the servo motor 19 is fixedly connected to a turntable 20. The turntable 20 is rotatably connected to the upper end of the lower frame 17, and a cleaning rod 21 is fixedly connected to the side wall of the turntable 20, and the cleaning rod 21 is slidably engaged with the upper end of the lower die 5.

[0032] After the arc extinguishing cover is unloaded, the servo motor 19 drives the turntable 20 to rotate, so that the turntable 20 drives the cleaning rod 21 to rotate, and the cleaning rod 21 scrapes off the debris on the upper end of the lower die 5.

[0033] like Figure 1 As shown, the lower end of the upper die 4 is fixedly connected with multiple sets of guide posts 22, and the lower die 5 is provided with multiple sets of guide grooves 23, and the multiple sets of guide posts 22 are respectively plugged into the multiple sets of guide grooves 23.

[0034] During stamping, the guide column 22 is plugged into the guide groove 23 to prevent the stamping from deflecting. The guide groove 23 does not contact the slide plate 13 , and some debris on the upper die 4 will fall through the guide groove 23 .

[0035] The working principle of the arc extinguishing hood forming machine provided by the utility model is as follows:

[0036] During operation, the workpiece is placed on the upper end of the stamping cavity 10, and the stamping cylinder 3 is used to control the upper die 4 to stamp the lower die 5, so that the stamping die 9 stamps the stamping cavity 10, and the arc extinguishing hood is stamped and formed. At this time, the upper die 4 and the lower die 5 are not separated, and the punching assembly is running to punch the formed arc extinguishing hood. The upper die 4 and the lower die 5 are separated, and the blanking assembly is compressed during stamping and reset after the stamping is completed, pushing the arc extinguishing hood to be demoulded, which is convenient for the arc extinguishing hood to be discharged. After the arc extinguishing hood is taken out, the cleaning assembly is run to clean the debris on the upper end of the lower die 5 to prevent the debris from affecting the molding quality of the arc extinguishing hood.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
