[0028] Reference Figure 1 As shown, the utility model provides a technical solution: a circular flanging device for sheet metal, comprising a flanging machine 1, a shaping disk 2 is installed on the surface of the flanging machine 1, and a feeding device 3 is provided on the surface of the flanging machine 1. By setting the feeding device 3, the effect of safely feeding the flanging machine 1 is achieved, and it is avoided that when the staff needs to flanging the sheet metal, the sheet metal is directly placed on the surface of the shaping disk 2 with the sheet metal held in hand while the flanging machine 1 is in a starting state, resulting in the shaping cone on the flanging machine 1 hitting the hands of the staff, thereby causing the staff to be injured, thereby improving the safety of the device, and a clamping device 4 is provided on the surface of the placing ring 305. By setting the clamping device 4, the effect of clamping the sheet metal placed on the shaping disk 2 is achieved, and it is avoided that the flanging machine 1 generates vibration during operation, and the vibration causes the sheet metal on the shaping disk 2 to shake, thereby causing the position of the sheet metal to shift, thereby improving the practicability of the device.
[0029] The specific arrangement and function of the feeding device 3 and the clamping device 4 will be described in detail below.
[0030] Reference Figure 2 and Figure 3As shown, in this embodiment: the feeding device 3 includes a round rod 301, the round rod 301 is rotatably connected to the surface of the flanging machine 1, the arc surface of the round rod 301 is slidably connected to a connecting plate 302, the lower surface of the connecting plate 302 is fixedly connected to a placing ring 305, the end of the round rod 301 away from the flanging machine 1 is fixedly connected to a handle 303, the placing ring 305 is slidably connected to the arc surface of the shaping disk 2, the surface of the flanging machine 1 is fixedly connected to a fixing plate 306, one side of the fixing plate 306 is fixedly connected to a fixing rod 307, the arc surface of the fixing rod 307 is slidably connected to an operating plate 308, the side of the operating plate 308 close to the fixing plate 306 is fixedly connected to an inserting rod 309, the surface of the connecting plate 302 is fixedly connected to a semicircular block 310, and the semicircular block 311 is fixedly connected to the fixing plate 312. The surface of 10 is provided with a slot. When the staff puts the sheet metal on the placement ring 305, the placement ring 305 drives the connecting plate 302 to slide on the arc surface of the round rod 301 until the placement ring 305 fits with the shaping disk 2. At this time, the operating plate 308 is pushed, and the operating plate 308 slides on the arc surface of the fixed rod 307. The operating plate 308 drives the insertion rod 309 to move until the insertion rod 309 is inserted into the slot of the semicircular block 310. At this time, the effect of the movement of the connecting plate 302 is achieved, and the shaking caused by the start-up of the flanging machine 1 causes the connecting plate 302 to slide on the round rod 301, thereby causing the sheet metal on the placement ring 305 to slip. The fixing rod 307 is fixedly connected to the limiting plate 311 at one end away from the fixing plate 306. The size of the insert rod 309 is matched with the size of the slot of the semicircular block 310. When the staff pulls the operating plate 308, the operating plate 308 slides on the arc surface of the fixed rod 307. At this time, the limit plate 311 achieves the effect of limiting the maximum sliding distance of the operating plate 308 on the arc surface of the fixed rod 307, thereby avoiding the situation that the operating plate 308 is separated from the arc surface of the fixed rod 307 due to excessive pulling force when the staff pulls the operating plate 308. The arc surface of the fixed rod 307 is sleeved with a first spring 312, and the two ends of the first spring 312 are fixedly connected to the operating plate 308 and the fixed plate 306 respectively. When the staff releases the operating plate 308, the resilience of the first spring 312 drives the operating plate 308 to move between the fixed rod 306 and the fixed rod 307. The arc surface of the round rod 301 slides, and the operating plate 308 drives the insertion rod 309 to move until the insertion rod 309 is inserted into the slot of the semicircular block 310. At this time, the first spring 312 improves the stability of the insertion rod 309 when limiting the semicircular block 310. The arc surface of the round rod 301 is sleeved with a second spring 304, and the two ends of the second spring 304 are respectively fixedly connected to the handle 303 and the connecting plate 302. When the staff releases the limiting of the semicircular block 310 by the insertion rod 309, the rebound force of the second spring 304 drives the connecting plate 302 to slide on the arc surface of the round rod 301. At this time, the second spring 304 achieves the effect of automatically taking the placement ring 305 away from the shaping disk 2, so as to reduce the staff's operating steps for the device and improve the staff's work efficiency.
[0031] Reference Figure 4 As shown, specifically, the clamping device 4 includes two L-shaped frames 41, both of which are fixedly connected to the placement ring 305, an L-shaped plate 42 is fixedly connected to the upper surface of the L-shaped frame 41, a driving rod 43 is inserted into the L-shaped plate 42 through an internal thread, one end of the driving rod 43 is rotatably connected to a clamping frame 44, a side of the clamping frame 44 away from the driving rod 43 is fixedly connected to an anti-slip pad 45, an end of the driving rod 43 away from the clamping frame 44 is fixedly connected to an operating block 46, and the clamping frame 44 close to the driving rod 43 is fixedly connected to the operating block 46. A positioning rod 47 is fixedly connected to one side, and the arc surface of the positioning rod 47 is slidably connected to the L-shaped plate 42. When the staff rotates the operating block 46, the operating block 46 drives the driving rod 43 to move in the inner thread of the L-shaped plate 42, and the driving rod 43 drives the clamping frame 44 to move. At the same time, the clamping frame 44 drives the positioning rod 47 to slide in the L-shaped plate 42. At this time, the positioning rod 47 has the effect of limiting the rotation of the clamping frame 44 following the driving rod 43, so as to improve the stability of the clamping frame 44 in clamping the sheet metal.
[0032] Working principle: when the staff needs to load the flanging machine 1, the sheet metal is placed on the placement ring 305, and the connecting plate 302 is pulled. The connecting plate 302 slides on the arc surface of the round rod 301, and the connecting plate 302 drives the placement ring 305 to move until the connecting plate 302 moves to the top of the round rod 301. At this time, the handle 303 is turned, and the handle 303 drives the round rod 301 to rotate on the flanging machine 1. At the same time, the connecting plate 302 drives the placement ring 305 to rotate until the placement ring 305 moves to the top of the shaping disk 2. At this time, the operating plate 308 is pulled, and the operating plate 308 slides on the arc surface of the fixed rod 307. The first spring 312 is stretched, and the operating plate 308 drives the insertion rod 309 to move until the insertion rod 309 no longer blocks the movement of the connecting plate 302. At this time, the connecting plate 302 is pressed downward to make the connecting plate 302 slide on the arc surface of the round rod 301, and the second spring 304 is stretched until the placement ring 305 is in contact with the shaping disk 2. At this time, the operating plate 308 is released, and the rebound force of the first spring 312 drives the operating plate 308 to slide on the arc surface of the fixed rod 307. At the same time, the operating plate 308 drives the insertion rod 309 to move until the insertion rod 309 is inserted into the slot of the semicircular block 310. At this time, the effect of safely loading the flanging machine 1 is achieved, which avoids the situation where the staff needs to flanging the sheet metal parts and directly places the sheet metal parts on the surface of the shaping disk 2 when the flanging machine 1 is in the starting state, causing the shaping cone on the flanging machine 1 to hit the hands of the staff, thereby causing injuries to the staff, thereby improving the safety of the device.
[0033] When the staff needs to clamp the sheet metal, they turn the operating block 46, which drives the driving rod 43 to move in the inner thread of the L-shaped plate 42, and the driving rod 43 drives the clamping frame 44 to move. At the same time, the clamping frame 44 drives the positioning rod 47 to slide in the L-shaped plate 42, and the clamping frame 44 drives the anti-slip pad 45 to move until the anti-slip pad 45 is clamped with the sheet metal. At this time, the sheet metal placed on the shaping disk 2 is clamped, avoiding the vibration of the flanging machine 1 during operation, which causes the sheet metal on the shaping disk 2 to shake, thereby causing the sheet metal to shift in position, thereby improving the practicability of the device.
