Description

Technical Field

[0001] The present invention relates to the technical field of hole and groove processing, and specifically to a light steel U-shaped plate hole and groove processing and forming machine. Background Art

[0002] In the field of construction engineering, light steel U-shaped plates, as efficient and lightweight prefabricated components, are widely used in building envelope structures, roofing systems, wall claddings, floor supports and other fields. U-shaped plates are usually roll-formed from cold-formed thin-walled steel strips into a U-shaped cross-section, and a large number of holes and grooves need to be processed on both side flanges and webs to meet functional requirements such as pipeline threading, bolt connection, ventilation and heat dissipation, or weight reduction. Traditional U-shaped plate hole and groove processing mostly adopts mechanical stamping forming process, that is, through the cooperation of a punch driven by hydraulic pressure or machinery and a die, high-speed blanking is carried out on the plate to form the target hole and groove.

[0003] Existing punching devices, such as a punching device for box-shaped plates proposed in the patent application number "CN206604930U", a column is provided on a base, a cross beam is provided at the upper end of the column, a first cylinder is provided on the cross beam, the piston rod of the first cylinder is vertically downward and connected to a movable cross beam, a driving block is provided on the movable cross beam, two first pressing blocks are provided on the base, punching heads for punching are respectively provided on the opposite surfaces of the two first pressing blocks, there are also two positioning blocks on the base, the front ends of the two positioning blocks are respectively arranged opposite to the opposite surfaces of the two first pressing blocks, the driving block drives the two positioning blocks to move away from or towards each other and respectively move away from or close to the two positioning blocks, a blanking hole for the punching head to pass through is provided on the two positioning blocks, the two positioning blocks are abutted against the outer wall of the box-shaped plate, and the punching head of the first pressing block is abutted against the inner wall of the box-shaped plate to be punched, so as to realize the punching operation on the box-shaped plate, and the punching head extends into the blanking hole of the two positioning blocks, which is convenient to realize the punching operation on the box-shaped plate and improve the hole forming efficiency.

[0004] However, in practical applications, the above-mentioned patented technology still reveals some significant deficiencies. Its design adopts the way that the punching head abuts against the inner wall of the box-shaped plate to be punched, and the punching head extends into the blanking hole of the two positioning blocks to realize the punching operation on the box-shaped plate. This makes the punching head and the blanking hole generate heat accumulation effect due to friction with the plate during long-term use, resulting in thermal fatigue of the punching head and the blanking hole, thus generating thermal expansion deformation, further causing the punching gap mismatch, accelerating the wear of the punching head, and reducing the punching accuracy and efficiency.

[0018] Beneficial effects of the present invention:

[0019] 1. The present invention sets a punching mechanism and a cooling mechanism for coordinated use, so that when the plate is driven to move toward one end of the hollow mold table, the two punch bodies are pushed to form a conflict with both sides of the plate and pass through the blanking hole, thereby completing the hole and groove forming of the plate.

[0020] 2. The present invention sets a punching mechanism and cooperates with the heat exchange nozzle, so that when driving the two punch bodies to punch and form holes on both sides of the U-shaped plate body, the two punch bodies are driven to move closer to each other, and the piston rod is pushed to squeeze the air inside the transmission sleeve rod. At the same time, the three-way ball valve is used to introduce the pressurized air into the interior of the heat exchange nozzle, and when the pressurized air passes through the interior of the heat exchange nozzle, it drives the coolant provided by the circulation pump to fully contact and exchange heat with the punch body, so as to reduce the internal temperature of the punch body and improve the punching accuracy and efficiency of the device.

[0021] 3. The present invention sets an arc-shaped electromagnet and uses it in conjunction with synchronous belt 2 and porous filler.

Then, the feeding valve is opened to release the closure of the feeding port, and the feeding motor is started to drive the feeding auger to push the metal debris collected inside the arc-shaped filter plate through the feeding port and discharge it from the inside of the collection bin, thereby facilitating the discharge of the metal debris collected inside the collection bin and effectively improving the practicality of the device.

Specific embodiments

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] A light steel U-plate hole and groove processing and forming machine, in which when the punching mechanism completes punching the workpiece, the cooling mechanism inputs coolant into the punch and uses the coolant to wash the hole and groove, as Figure 1 and Figure 3 shown, the cooling mechanism inputs pressurized gas and coolant into the heat exchange nozzle, so as to use the coolant to cool the heat exchange nozzle, which belongs to a kind of hole and groove processing device.

[0040] As Figures 1 - 10As shown, it includes a base 1. Symmetrically fixed to the top of the base 1 are roller frames 2. Fixed to the top of the base 1 is a hollow die table 3. At one end of the hollow die table 3, punch bodies 4 are symmetrically installed, and at one end of the hollow die table 3, blanking holes 5 adapted to the punch bodies 4 are symmetrically opened. Inside the punch bodies 4, heat exchange nozzles 6 are opened. Inside the base 1, a collection bin 7 communicating with the inside of the hollow die table 3 is opened.

[0041] At one end of the base 1, a punching mechanism for continuously conveying and punching sheet materials is installed. At one end of the base 1, a cooling mechanism for conveying coolant through the heat exchange nozzles 6 to exchange heat with the punch bodies 4 for temperature reduction is installed. Inside the base 1, a separation mechanism for classifying and collecting the coolant and debris is installed. Inside the base 1, a sewage discharge mechanism for discharging the debris is installed.

[0042] During use, first start the punching mechanism to continuously convey the sheet material to the outer periphery of the top of the hollow die table 3. At the same time, push the two punch bodies 4 to move towards each other, and push both sides of the sheet material through the inside of the blanking holes 5 to complete the punching of the sheet material. At the same time, set the cooling mechanism to input pressurized air and coolant into the inside of the heat exchange nozzles 6 during the process of the punch bodies 4 punching the sheet material, so that the pressurized air pushes the coolant through the inside of the heat exchange nozzles 6, and flushes the inner walls of the blanking holes 5 and the sheet material hole grooves, so that when the coolant passes through the inside of the heat exchange nozzles 6, it forms contact heat exchange with the inner wall of the heat exchange nozzles 6, quickly reducing the temperature inside the heat exchange nozzles 6, and at the same time flushing away the residual punching debris on the inner walls of the sheet material hole grooves and the blanking holes 5 to reduce the accumulation of debris on the inner walls of the blanking holes 5 and the sheet material hole grooves, resulting in punching jams.

[0043] Then set the separation mechanism to separate and collect the coolant that has flushed the inner walls of the blanking holes 5 and the sheet material hole grooves, so that the separated coolant flows into the inner bottom of the collection bin 7 for collection and cooling. Then use the sewage discharge mechanism to discharge the separated metal debris from the inside of the collection bin 7, so as to facilitate the real-time temperature reduction of the punch bodies 4, and at the same time realize the flushing of the inner walls of the blanking holes 5 and the sheet material hole grooves, effectively reducing the heat accumulation effect inside the punch bodies 4, reducing the wear of the punch bodies 4, and improving the punching accuracy and efficiency of the device.

[0044] Such as Figures 1 - 6As shown in the figure, the punching mechanism includes an arch frame 8 fixedly connected to the top of the base 1. A feeding motor 9 is fixedly connected to the top of the arch frame 8. The output end of the feeding motor 9 is fixedly connected to a first synchronous pulley 10. The top of the base 1 is symmetrically rotatably connected with support rollers 11, and the top of the base 1 is symmetrically rotatably connected with pressing rollers 12. The pressing rollers 12 are installed above the support rollers 11. One end of the pressing roller 12 is fixedly connected to a second synchronous pulley 13. A first synchronous belt 14 is sleeved on the outer peripheries of the first synchronous pulley 10 and the second synchronous pulley 13. Rubber sleeves are fixedly sleeved on the outer peripheries of the support rollers 11 and the pressing rollers 12. A U-shaped plate body 15 is inserted between the pressing roller 12 and the support roller 11. One end of the arch frame 8 is provided with a punching assembly for driving the two punch bodies 4 to move away from or close to each other;

[0045] Among them, the punching assembly includes a hydraulic rod 16 fixedly connected to the top of the arch frame 8. The output end of the hydraulic rod 16 is fixedly connected to a lifting plate 17. Symmetrically fixed to the top of the lifting plate 17 are lifting slide rods 18. The lifting slide rods 18 are slidably connected to the arch frame 8. One end of the lifting plate 17 is slidably connected with four pressing slide rods 19. The four pressing slide rods 19 are arranged in a rectangle. The bottom of the four pressing slide rods 19 is fixedly connected to a pressing plate 20. A pressing spring 21 is sleeved on the outer periphery of the pressing slide rod 19. The pressing spring 21 is installed between the pressing plate 20 and the lifting plate 17. Symmetrically fixed to the bottom of the lifting plate 17 are abutting inclined blocks 22. The top of the punch body 4 is rotatably connected with an abutting roller 23 adapted to the abutting inclined block 22. Symmetrically fixed to one end of the hollow mold table 3 are guiding slide rods 24. The punch body 4 is slidably connected with the guiding slide rods 24. A return spring 25 is sleeved on the outer periphery of the guiding slide rod 24. The return spring 25 is installed between the punch body 4 and the hollow mold table 3.

[0046] During use, first, one end of the U-shaped plate body 15 is drawn through between the pressing roller 12 and the support roller 11, and the pressing roller 12 and the support roller 11 form a rolling abutment against one end of the U-shaped plate body 15. At the same time, the feeding motor 9 is started to drive the first synchronous pulley 10 to rotate, and the first synchronous pulley 10 cooperates with the first synchronous belt 14 to drive the two second synchronous pulleys 13 to rotate synchronously, so that the second synchronous pulley 13 drives the pressing roller 12 to push the U-shaped plate body 15 to move along the length direction of the roller frame 2, so that the pressing roller 12 pushes the U-shaped plate body 15 to continuously move towards the hollow mold table 3 to realize continuous feeding of the U-shaped plate body 15;

[0047] At the same time, the hydraulic rod 16 is started to push out the lifting plate 17 along the length direction of the lifting slide bar 18, so that the lifting plate 17 drives the pressing plate 20 to form a conflict with the top of the U-shaped plate body 15. At this time, the elastic characteristics of the pressing spring 21 are used to make the pressing spring 21 push out the pressing plate 20 along the length direction of the pressing slide bar 19, and make the pressing plate 20 push the top of the U-shaped plate body 15 and the top of the hollow mold table 3 to form a preliminary press fit, and then the hydraulic rod 16 continues to push out the lifting plate 17, and make the lifting plate 17 squeeze the pressing spring 21 along the length direction of the pressing slide bar 19 to produce a contraction deformation, and at the same time make the lifting plate 17 push the pressing plate 20 to form a conflict and press fit with the top of the U-shaped plate body 15;

[0048] Then, when the lifting plate 17 approaches the top of the hollow die table 3 along the length direction of the lifting slide bar 18, the lifting plate 17 drives the oblique block 22 to form rolling contact with the contact roller 23, and pushes the punch body 4 to be inserted into the blanking hole 5 along the length direction of the guide slide bar 24, and the punch body 4 pushes one end of the U-shaped plate body 15 through the blanking hole 5, and at the same time, the punch body 4 squeezes the return spring 25 to produce a contraction deformation, so that the punch body 4 completes the punching of the U-shaped plate body 15;

[0049] Then, the hydraulic rod 16 is started in reverse to lift the lifting plate 17 along the length direction of the lifting slide bar 18, so that the pressure spring 21 is relieved of the force and the pressing plate 20 is pushed out along the length direction of the pressing slide bar 19. At the same time, the lifting plate 17 drives the resistance inclined block 22 to break away from the rolling resistance with the resistance roller 23, and relieves the force of the return spring 25, and pushes the punch body 4 out along the length direction of the guide slide bar 24, so that one end of the punch body 4 is separated from the inside of the blanking hole 5.

[0050] like Figures 1 - 5 and Figures 7 - 10 As shown, the cooling mechanism includes a circulation pump 26 fixedly connected to one side of the base 1, the input end of the circulation pump 26 is connected to the interior of the collection bin 7 through a pipeline, the output end of the circulation pump 26 is symmetrically fixedly connected with a liquid infusion pipe 27, the inner side of the heat exchange nozzle 6 near the blanking hole 5 is set to be conical, and the inner wall of the heat exchange nozzle 6 is evenly and fixedly connected with a plurality of heat exchange fins 28, the top of the base 1 is symmetrically rotatably connected with a guide roller 29, the middle section of the liquid infusion pipe 27 bypasses the top of the guide roller 29, and one end of the base 1 is equipped with a transmission component for inputting pressurized gas into the heat exchange nozzle 6.

[0051] Among them, the transmission assembly includes a transmission sleeve rod 30 symmetrically fixedly connected to the top of the hollow mold table 3, one end of the lifting plate 17 is symmetrically fixedly connected to a piston rod 31, the top of the piston rod 31 is slidably connected to the inside of the transmission sleeve rod 30, and the bottom of the transmission sleeve rod 30 is fixedly connected to a three-way ball valve 32, the output end of the three-way ball valve 32 is fixedly connected to an air pipe 33, the output end of the air pipe 33 is fixedly connected to the input end of the heat exchange nozzle 6, and the input end of the three-way ball valve 32 is connected to the external air.

[0052] When in use, first, when the punching mechanism is started to drive the two punch bodies 4 to move closer to each other, the lifting plate 17 drives the piston rod 31 to move downward along the length direction of the transmission sleeve rod 30, and the piston rod 31 compresses the air inside the transmission sleeve rod 30 for pressurization, and at the same time, the three-way ball valve 32 is started to introduce the pressurized gas inside the transmission sleeve rod 30 into the interior of the heat exchange nozzle 6 through the air pipe 33. At this time, the circulation pump 26 is started to draw the coolant inside the collection bin 7 into the output end of the heat exchange nozzle 6 through the liquid infusion pipe 27, so that the pressurized gas pushes the coolant through the interior of the heat exchange nozzle 6. The coolant is flushed toward the inner wall of the blanking hole 5 and the hole groove of the U-shaped plate body 15, so that the coolant can fully contact and exchange heat with the punch body 4 through the heat exchange fins 28 when passing through the inside of the heat exchange nozzle 6. At the same time, the conical inner wall inside the heat exchange nozzle 6 is used to reduce the output diameter of the coolant, and the pressure of the coolant flushing the blanking hole 5 and the inner wall of the hole groove of the U-shaped plate body 15 is further increased, so as to realize the real-time heat exchange and cooling inside the punch body 4, reduce the heat accumulation effect inside the punch body 4, and reduce the jamming caused by the accumulation of debris inside the blanking hole 5 and the hole groove of the U-shaped plate body 15;

[0053] Similarly, when the punching mechanism is started in reverse to drive the punch body 4 to leave the inside of the blanking hole 5, the lifting plate 17 drives the piston rod 31 to move upward along the length direction of the transmission sleeve 30. At this time, the three-way ball valve 32 is started to close the input end of the air pipe 33, and the inside of the transmission sleeve 30 is connected with the external air, so that the external air is sucked into the inside of the transmission sleeve 30 through the three-way ball valve 32 to maintain the air pressure inside the transmission sleeve 30.

[0054] like Figures 1 - 3 and Figures 9 - 13As shown in the figure, the separation mechanism includes an inverted V-shaped drainage plate 34 fixedly connected inside the collection bin 7.

Inside the collection bin 7, a filtering assembly is installed for secondary filtering of the separated coolant;

[0055] Among them, the rotating assembly includes a first bevel gear 41 fixedly connected to one end of the separation roller 56.

[0056] Moreover, the filtering assembly includes support inclined plates 45 symmetrically and fixedly connected inside the collection bin 7. At the top of the support inclined plates 45, porous fillers 46 are fixedly connected. At the bottom of the V-shaped collection plate 35, an arc-shaped filter plate 47 is fixedly connected.

[0057] During use, when starting the cooling mechanism to flush the inner walls of the blanking hole 5 and the U-shaped plate body 15 through the coolant, the coolant carries metal debris through the hollow mold table 3 and falls into the collection bin 7 for collection. At the same time, when the coolant passes through the hollow mold table 3 and falls into the collection bin 7, the coolant slides down along the top of the inverted V-shaped drainage plate 34 to the top of the two second synchronous belts 37, and the coolant slides down along the top of the second synchronous belts 37. At the same time, start the arc-shaped electromagnets 36 to generate a magnetic adsorption field, so that the arc-shaped electromagnets 36 adsorb the metal debris carried in the coolant through the second synchronous belts 37. The coolant separated from the metal debris slides down to the top of the support inclined plates 45 along the top of the second synchronous belts 37, passes through the inside of the porous fillers 46, and then slides down to the inner bottom of the collection bin 7 for collection. At the same time, the porous fillers 46 are set as activated carbon fiber filter blocks. When the coolant passes through the inside of the porous fillers 46, the adsorption characteristics of the porous fillers 46 are used to adsorb and collect the grease, organic matter and non-metallic particles in the coolant, so as to further filter the coolant and improve the purity of the coolant;

[0058] At the same time, the rotating motor 44 is started to drive the connecting rod 42 to drive the bevel gear 2 43 to rotate, and drive the bevel gear 2 43 to engage with the bevel gear 1 41, and at the same time, the bevel gear 1 41 drives the separation roller 56 to rotate, so that the separation roller 56 drives the synchronous belt 2 37 to circulate around the outer periphery of the arc-shaped electromagnet 36, and then the synchronous belt 2 37 drives the metal debris adsorbed on the surface to transfer to the top of the V-shaped collecting plate 35. At this time, the metal debris adsorbed on the surface of the synchronous belt 2 37 is separated from the adsorption range of the arc-shaped electromagnet 36, and falls into the inside of the V-shaped collecting plate 35 under the action of gravity for collection, thereby facilitating the classification and collection of coolant and metal debris, effectively improving the cooling efficiency of the coolant on the punch body 4, and further improving the punching efficiency of the punch body 4.

[0059] like Figures 1 - 3 and Figures 10 - 13 As shown, the sewage discharge mechanism includes a roller brush 48 symmetrically connected to the inside of the collection bin 7, one end of the roller brush 48 is fixedly connected to a synchronous wheel 3 49, one end of the separation roller 56 is fixedly connected to a synchronous wheel 4 50, and the outer peripheries of the synchronous wheels 3 49 and 4 50 are sleeved with a synchronous belt 3 51, and a material discharge assembly for discharging debris is installed inside the collection bin 7;

[0060] Among them, the unloading component includes a unloading port 52 opened at one end of the collecting bin 7, one end of the unloading port 52 is connected to the interior of the arc filter plate 47, a unloading valve 53 is fixedly connected to the interior of the unloading port 52, and a unloading auger 54 is rotatably connected to the interior of the collecting bin 7. The unloading auger 54 is installed inside the arc filter plate 47, and a unloading motor 55 is fixedly connected to one end of the base 1, and the output end of the unloading motor 55 is fixedly connected to the unloading auger 54.

[0061] When in use, when the rotating assembly is started to drive the separation roller 56 to rotate, and the synchronous belt 2 37 is driven to transfer the metal debris adsorbed by the arc-shaped electromagnet 36 to the top of the V-shaped collecting plate 35, the separation roller 56 drives the synchronous wheel 4 50 to rotate synchronously, and at the same time, the synchronous wheel 4 50 cooperates with the synchronous belt 3 51 to drive the synchronous wheel 3 49 to rotate synchronously, and the synchronous wheel 3 49 drives the roller brush 48 to rotate and brush the surface of the synchronous belt 2 37 passing through the adjusting roller 39 and the roller brush 48, so that the metal debris adhered to the surface of the synchronous belt 2 37 is separated and falls into the inside of the V-shaped collecting plate 35 for collection;

[0062] At the same time, the metal debris that falls into the V-shaped collecting plate 35 slides down to the inside of the arc filter plate 47 under the action of gravity for filtration and collection, and then the discharge port 52 is released from the blockage by opening the discharge valve 53, and at the same time, the discharge motor 55 is started to drive the discharge auger 54 to rotate, and the discharge auger 54 pushes the metal debris collected in the arc filter plate 47 through the discharge port 52 and is discharged from the interior of the collection bin 7.

[0063] The working principle of a light steel U - plate hole - groove processing and forming machine provided by the present invention is as follows:

[0064] First, start the feeding motor 9 to drive the first synchronous wheel 10 to rotate, and make the first synchronous wheel 10 cooperate with the first synchronous belt 14 to drive the two second synchronous wheels 13 to rotate synchronously, so that the second synchronous wheel 13 drives the pressing roller 12 to push the U - shaped plate body 15 to move along the length direction of the roller frame 2. At the same time, start the hydraulic rod 16 to push out the lifting plate 17 along the length direction of the lifting slide rod 18, so that the lifting plate 17 drives the pressing plate 20 to form a contact with the top of the U - shaped plate body 15, and at the same time, the lifting plate 17 pushes the pressing plate 20 to form a contact press with the top of the U - shaped plate body 15;

[0065] Then, when the lifting plate 17 approaches the top of the hollow die table 3 along the length direction of the lifting slide rod 18, the lifting plate 17 drives the contact inclined block 22 to form a rolling contact with the contact roller 23, and pushes the punch body 4 to insert into the inside of the blanking hole 5 along the length direction of the guiding slide rod 24, and makes the punch body 4 push one end of the U - shaped plate body 15 through the inside of the blanking hole 5, so that the punch body 4 completes the punching and forming of the U - shaped plate body 15;

[0066] At the same time, the lifting plate 17 drives the piston rod 31 to move downward along the length direction of the transmission sleeve rod 30, and the piston rod 31 compresses the air inside the transmission sleeve rod 30 for pressurization. At the same time, start the three - way ball valve 32 to introduce the pressurized gas inside the transmission sleeve rod 30 into the inside of the heat - exchange spray nozzle 6 through the air pipe 33. At this time, start the circulating pump 26 to pump the coolant inside the collection bin 7 into the output end of the heat - exchange spray nozzle 6 through the liquid - conveying pipe 27, so that the pressurized gas pushes the coolant to pass through the inside of the heat - exchange spray nozzle 6 and rush towards the inner wall of the blanking hole 5 and the hole - groove of the U - shaped plate body 15. Furthermore, when the coolant passes through the inside of the heat - exchange spray nozzle 6, it makes full contact heat - exchange with the punch body 4 through the heat - exchange fins 28. At the same time, use the conical inner wall inside the heat - exchange spray nozzle 6 to reduce the output diameter of the coolant, so that the coolant flushes the punching debris remaining on the inner wall of the blanking hole 5 and the hole - groove of the U - shaped plate body 15;

[0067] Then, when the coolant passes through the hollow die table 3 and falls into the collection bin 7, the coolant is guided to slide down along the top of the inverted V - shaped diversion plate 34 to the top of the two second synchronous belts 37, and start the arc electromagnet 36 to generate a magnetic adsorption magnetic field, so that the arc electromagnet 36 adsorbs the metal debris carried in the coolant through the second synchronous belt 37. When the coolant separated from the metal debris slides to the top of the support inclined plate 45, using the adsorption characteristics of the porous filler 46, the grease, organic matter and non - metal particles in the coolant are adsorbed and collected. After passing through the inside of the porous filler 46, it slides to the inner bottom of the collection bin 7 for collection;

[0068] At the same time, the rotating motor 44 is started to drive the connecting rod 42 to drive the bevel gear 2 43 to rotate, and drive the bevel gear 2 43 to mesh with the bevel gear 1 41, and at the same time, the bevel gear 1 41 drives the separation roller 56 to rotate, so that the separation roller 56 drives the synchronous belt 2 37 to circulate around the outer periphery of the arc-shaped electromagnet 36, and then the synchronous belt 2 37 drives the metal debris adsorbed on the surface to transfer to the top of the V-shaped collecting plate 35. At this time, the metal debris adsorbed on the surface of the synchronous belt 2 37 is separated from the adsorption range of the arc-shaped electromagnet 36, and falls into the inside of the V-shaped collecting plate 35 under the action of gravity for collection;

[0069] Finally, the separation roller 56 is used to drive the synchronous wheel four 50 to rotate synchronously, and the synchronous wheel four 50 cooperates with the synchronous belt three 51 to drive the synchronous wheel three 49 to rotate synchronously, and the synchronous wheel three 49 drives the roller brush 48 to form a rotational brushing on the surface of the synchronous belt two 37 passing through the adjusting roller 39 and the roller brush 48, so that the metal debris adhered to the surface of the synchronous belt two 37 is detached and falls into the inside of the V-shaped collecting plate 35 for collection, and then the discharge valve 53 is opened to release the closure of the discharge port 52, and at the same time, the discharge motor 55 is started to drive the discharge auger 54 to rotate, and the discharge auger 54 pushes the metal debris collected inside the arc filter plate 47 through the discharge port 52 and discharged from the inside of the collection bin 7.
