Technical Field

[0001] The invention relates to the technical field of edge milling, and in particular to a device and method for edge milling of sheet metal parts of a filing cabinet. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates. The products processed by the sheet metal process are called sheet metal parts, among which polygonal nuts are common sheet metal parts. During the production process of file cabinets, polygonal nuts are needed to assemble various components. During the nut production process, the edges of the nuts need to be milled. However, in the prior art, it is not convenient to mill the polygonal nuts when milling the nuts. At the same time, after milling the top edge, the nut needs to be taken out of the device, turned over, and installed on the device again to mill the other side, which is time-consuming and labor-intensive. At the same time, a large amount of debris will be generated during the milling process. Failure to clean it in time will affect subsequent operations and pose a great safety hazard.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are:

[0020] 1. The present invention proposes a file cabinet sheet metal milling device and method, which moves the milling cutter on the mounting frame to the required position, and then the connecting pipe drives the milling cutter to rotate, and the sheet metal body can be milled at this time. During the milling process, the rotating rod rotates intermittently, and cooperates with the first gear through the first incomplete gear.

[0022] 3. The present invention provides a file cabinet sheet metal milling device and method, which, after milling the sheet metal body, drives the positioning box to move through the sliding seat, and drives the sheet metal body on the surface to move horizontally by flipping. When moving to the position of the brush, the connecting pipe rotates to drive the brush on the surface to clean the surface to prevent small debris from adhering to the surface.

At this time, the debris on the surface of the sheet metal body can be cleaned in time. When the baffle moves in the opposite direction, the airflow can be pushed into the air outlet hole on the milling cutter and blown toward the sheet metal body along the air guide groove on the milling cutter. During the milling process, the debris on the surface can be processed in time to prevent the accumulation of debris, and the air flow and cleanliness in the working area can be ensured to be in the best state. At the same time, the safety of work is also improved to prevent the milling cutter from being touched when cleaning the debris, causing safety hazards.

[0023] 4. The present invention proposes a device and method for milling the sheet metal of a filing cabinet. When the positioning box is moved to the guide plate away from the milling cutter side, the clamping rod on the top of the positioning box contacts the guide groove, so that the clamping rod moves along the guide groove, so that the third gear can be driven to move above the rack and engage with it. At this time, the third gear can drive the round rod to flip, so that the flip frame drives the sheet metal body on the top to flip. During the flipping process, debris on the surface of the flip frame will fall off, and the airflow ejected by the connecting pipe can clean the dead corners, so that the debris can fall into the debris box for centralized collection.

[0024] 5. The present invention proposes a device and method for milling sheet metal parts of a filing cabinet, which drives the flip frame to flip when the third gear is meshed with the rack. At this time, the sheet metal body is downward. When the sheet metal body moves to the top of the material receiving box, the clamping assembly is released. At this time, the sheet metal body can fall into the material receiving box, which is convenient for centralized collection of the sheet metal bodies after milling. The flipping frame can complete the collection of the sheet metal bodies more quickly, thereby shortening the collection time and improving the overall production efficiency and safety.

During flipping, the positioning plate 307 disengages from the limiting frame 207, and the flipped positioning plate 307 slides back into the limiting frame 207, and the limiting frame 207 drives the positioning plate 307 to rotate, and the positioning plate 307 drives the clamping frame 209 to rotate intermittently.

[0039] like Figure 1-7 As shown, a processing mechanism 4 is also provided on the top of the frame 1, and the milling mechanism 2 includes an adjusting frame 401, the surface of the adjusting frame 401 is fixedly connected to a mounting frame 402, the outer surface of the mounting frame 402 is rotatably connected to a connecting tube 403 through a bearing, the outer surface of the connecting tube 403 is fixedly connected to a milling cutter 404, and the surface of the milling cutter 404 is provided with an air guide groove.

[0042] The effect is that when the sheet metal body 210 moves to the position of the brush 505, the connecting tube 403 rotates and drives the brush 505 on the surface to clean its surface. At the same time, the connecting tube 403 rotates and drives the reciprocating thread groove on the surface to rotate. The reciprocating thread groove drives the baffle 507 on the surface to move back and forth inside the air supply pipe 506. Both the air inlet pipe 508 and the connecting tube 403 are equipped with a one-way valve, so that when the baffle 507 moves toward the milling cutter 404, the baffle 507 draws the external airflow from the air inlet pipe 508 to the inside of the air supply pipe 506.

At this time, the debris on the surface of the sheet metal body 210 can be cleaned.

[0043] like Figure 1-7As shown, a feeding mechanism 6 is also provided on the top of the frame 1, and the feeding mechanism 6 includes a rack 601, a third gear 602 is fixedly connected to the outer surface of the round rod 504, the third gear 602 is meshed with the rack 601, the outer surface of the round rod 504 is rotatably connected to a moving frame 603 through a bearing, a sliding groove is provided on the outer surface of the positioning box 503, the moving frame 603 is slidably connected to the sliding groove, a clamping rod 604 is fixedly connected to the upper surface of the moving frame 603, and a guide is fixedly connected to the outer surface of the frame 1.

[0044] The effect is that when the positioning box 503 moves to the guide plate 605 on the side away from the milling cutter 404, the clamping rod 604 on the top of the positioning box 503 contacts the guide groove, so that the clamping rod 604 moves along the guide groove and drives the moving frame 603 to move, and the moving frame 603 drives the round rod 504 to move, and the round rod 504 drives the third gear 602 to move and contact the rack 601, and the third gear 602 is meshed with the rack 601.

At this time, the debris on the surface of the flip frame 201 can fall into the debris box 11 with the help of the airflow on the brush 505. When the sheet metal body 210 moves to the top of the material receiving box 8, the clamping assembly is released. At this time, the sheet metal body 210 can fall into the material receiving box 8. When it continues to move toward the milling cutter 404, the clamping rod 604 contacts the guide groove on the guide plate 605 on the other side, which can drive the round rod 504 to move and push the third gear 602 away from the plane where the rack 601 is located.

[0045] like Figure 1-7 As shown, a file cabinet sheet metal milling method includes the following steps:

[0046] S1: The sheet metal body 210 is mounted on the clamping frame 209 , and the milling cutter 404 performs milling processing on the sheet metal body 210 . The sheet metal body 210 inside the clamping frame 209 is intermittently rotated, and multiple sides of the sheet metal can be milled.

[0047] S2: The clamping frame 209 drives the sheet metal body 210 inside to flip over, and performs milling processing on the edge of the bottom of the sheet metal body 210.

[0048] S3: The electric slide rail drives the sheet metal body 210 to move horizontally. When it moves to the position of the brush 505, the brush 505 cleans the surface thereof, and the connecting pipe 403 is blown up at the same time to clean the debris on the surface of the sheet metal body 210 in time.

[0049] S4: The clamping rod 604 at the top of the positioning box 503 contacts the guide groove, causing the third gear 602 to move and engage with it. At this time, the third gear 602 can drive the flip frame 201 to flip. During the flipping process, debris on the surface of the flip frame 201 will fall off, and the airflow ejected by the connecting pipe 403 will clean the dead corners.

[0050] S5: The turning frame 201 continues to move after turning over. When the sheet metal body 210 moves to above the material receiving box 8, the clamping assembly is released. At this time, the sheet metal body 210 can fall into the material receiving box 8 for collection.

[0051] The working principle is that the sheet metal body 210 is clamped and positioned by the clamping assembly on the clamping frame 209, and then the milling cutter 404 on the mounting frame 402 is moved to a suitable position through the adjusting frame 401, and the second motor 10 drives the connecting pipe 403 to rotate, and the connecting pipe 403 drives the milling cutter 404 to rotate. At this time, the sheet metal body 210 can be milled. During the milling process, the second motor 10 drives the rotating rod 202 to rotate intermittently, and the rotating rod 202 drives the first incomplete gear 203 to rotate, and the first incomplete gear 203 drives the first gear 204 to rotate. The first motor 9 is a stepping motor with programmability to achieve precise rotation angles, so that it can be suitable for edge-shaped sheet metal parts. The first gear 204 drives the support rod 20 5 rotates, the support rod 205 drives the limit frame 207 to rotate, the limit frame 207 drives the positioning plate 307 to rotate, and the positioning plate 307 drives the clamping frame 209 to rotate intermittently. During the intermittent rotation, the milling cutter 404 can mill the edge of the sheet metal body 210 through the adjustment frame 401. When the toothed portion of the first incomplete gear 203 is in meshing with the first gear 204, the first gear 204 can just rotate one circle. After the first gear 204 rotates one circle, the incomplete gear is not in mesh with the first gear 204. At this time, the incomplete gear drives the second incomplete gear 301 to rotate through the rotating rod 202. The second incomplete gear 301 is in meshing with the second gear 302, and can drive the second gear 302 to rotate one circle. The second gear 302 The vertical rod 303 is driven to rotate, and the vertical rod 303 drives the first bevel gear 305 to rotate one circle. The first bevel gear 305 drives the second bevel gear 306 to rotate half a circle. The second bevel gear 306 drives the cross bar 208 to rotate, and the cross bar 208 drives the clamping frame 209 to rotate. The clamping frame 209 drives the internal sheet metal body 210 to flip. When flipping, the positioning plate 307 is separated from the limiting frame 207, and the positioning plate 307 after flipping slides back into the limiting frame 207. At this time, the limiting frame 207 can continue to drive the positioning plate 307 to rotate and perform milling on the edge of the bottom of the sheet metal body 210. After the sheet metal body 210 is milled, the electric slide rail drives the sliding seat 502 to move, and the sliding seat 502 drives the positioning box 503 to move. The turning plate is driven to move by the round rod 504, and the turning plate drives the sheet metal body 210 on the surface to move. When it moves to the position of the brush 505, the connecting pipe 403 rotates to drive the brush 505 on the surface to clean the surface. At the same time, the connecting pipe 403 rotates to drive the reciprocating thread groove on the surface to rotate, and the reciprocating thread groove drives the baffle 507 on the surface to move back and forth inside the air supply pipe 506. The air inlet pipe 508 and the connecting pipe 403 are both equipped with a one-way valve, so that when the baffle 507 moves toward the milling cutter 404, the baffle 507 draws the external airflow from the air inlet pipe 508 to the inside of the air supply pipe 506. When the baffle 507 moves to the other side of the milling cutter 404, the gas in the air supply pipe 506 can be pushed into from the air inlet hole.The positioning box 503 moves to the guide plate 605 on the side away from the milling cutter 404, and the clamping rod 604 on the top of the positioning box 503 contacts the guide groove, so that the clamping rod 604 moves along the guide groove and drives the moving frame 603 to move. The moving frame 603 drives the round rod 504 to move, and the round rod 504 drives the third gear 602 to move and contact the rack 601. The third gear 602 meshes with the rack 601. At this time, the third gear 602 can drive the round rod 504 to flip, and the round rod 504 The turning frame 201 is driven to rotate, and the turning frame 201 drives the sheet metal body 210 on the top to turn over. At this time, the debris on the surface of the turning frame 201 can fall into the debris box 11 with the airflow on the brush 505. When the sheet metal body 210 moves to the top of the material receiving box 8, the clamping assembly is released, and the sheet metal body 210 can fall into the material receiving box 8. When it continues to move toward the milling cutter 404, the clamping rod 604 contacts the guide groove on the other side guide plate 605, which can drive the round rod 504 to move and push the third gear 602 away from the plane where the rack 601 is located.
