Technical Field
[0001] The utility model relates to the field of bending devices, in particular to a bending device for manufacturing metal elbows. Background Technique
[0002] A bending device for manufacturing metal elbows is mainly used to bend metal elbows into required shapes. It uses a mold to bend metal elbows in a cold state into workpieces with various geometric cross-sectional shapes. This device is a forming machine designed for cold-rolled sheet metal processing and is widely used in multiple industries, such as automobile, aircraft manufacturing, light industry, shipbuilding, railway vehicles, etc.
[0003] However, in the prior art, when bending metal elbows at different angles, the device can only restrict it through a bending rod and cannot restrict the top of the metal elbow, resulting in the overall upward displacement of the metal elbow during bending, thereby causing a change in the bending angle of the metal elbow during bending, affecting the size and accuracy of bending, and reducing efficiency. Therefore, it is necessary to improve a bending device for manufacturing metal elbows to solve the above problems. Summary of the Utility Model
[0004] In order to overcome the problem that the metal elbow will be displaced upward as a whole during bending, resulting in a change in the bending angle of the metal elbow during bending, affecting the size and accuracy of bending, and reducing efficiency.
[0005] The technical solution of the utility model is: a bending device for manufacturing metal elbows, which includes a workbench, support legs, a first baffle, and a second baffle. It also includes a cross-shaped pressing plate, a base, a fixed shaft, and a bending assembly. The bottom of the workbench is fixedly connected with support legs. The top of the workbench is provided with a first baffle and a second baffle. The top of the workbench is provided with a bending assembly. The inside of the first baffle and the second baffle are both slidably connected with a cross-shaped pressing plate. The top of the cross-shaped pressing plate is fixedly connected with a base. The inside of the base is rotatably connected with a fixed shaft. Through the fixed shaft and the base, the cross-shaped pressing plate at the bottom is driven to move up and down.
[0006] Preferably, by rotating the hexagonal rotating block, the bidirectional threaded rod inside the first limiting block and the second limiting block is rotated, so that the first hexagonal movable block and the second hexagonal movable block slide outside the bidirectional threaded rod, thereby driving the base outside the connecting fixed shaft by the first movable plate and the second movable plate to slide up and down, and then driving the cross-shaped pressing plate to slide up and down, so as to press metal elbows of different sizes, so that the bending angle of the metal elbow will not deviate due to improper clamping during bending, thereby improving the stability of the device and improving work efficiency. By driving the rotating plate by a motor, the first bending shaft and the second bending shaft can bend along the outer wall of the first disc or the second disc. Since the diameters of the first disc and the second disc are different, the bending angles are also different, so that a device can bend into different angles, improving the practicability of the device. Through the slots opened inside the rotating plate, the positions of the first fixing block and the second fixing block can drive the first bending shaft and the second bending shaft to be adjusted, and then fixed by the first bolt and the second bolt, so that it can be adjusted according to elbows of different diameters, increasing work efficiency.

The bottom of the second fixing block is fixedly connected to a second bending shaft. A first bolt is threadedly connected between the first fixing block and the rotating plate. A second bolt is threadedly connected between the second fixing block and the rotating plate. By driving the rotating plate by a motor, the first bending shaft and the second bending shaft can bend along the outer wall of the first disc or the second disc. Since the diameters of the first disc and the second disc are different, the bending angles are also different, so that a device can bend into different angles, improving the practicability of the device.
[0008] Preferably, slots are opened at the corresponding positions of the rotating plate for the first fixing block and the second fixing block. The first fixing block and the second fixing block move inside the slots. A first baffle is fixedly connected to the top of the bottom plate. A second baffle is fixedly connected to the top of the first disc. Through the slots opened inside the rotating plate, the positions of the first fixing block and the second fixing block can drive the first bending shaft and the second bending shaft to be adjusted, and then fixed by the first bolt and the second bolt, so that it can be adjusted according to elbows of different diameters, increasing work efficiency.
[0009] Preferably, first limit blocks are provided at the tops of the first baffle and the second baffle. A bidirectional threaded rod is rotatably connected inside the first limit block, and a second limit block is rotatably connected to the outside of the bidirectional threaded rod. A hexagonal rotating block is fixedly connected to the left side of the bidirectional threaded rod.

The outside of the first hexagonal movable block is rotatably connected with a second movable plate, and the outside of the second hexagonal movable block is rotatably connected with a first movable plate. Both the first movable plate and the second movable plate are rotatably connected to the outside of a fixed shaft. By rotating the hexagonal rotating block, the bidirectional threaded rod inside the first limit block and the second limit block is driven to rotate, thereby driving the cross-shaped pressing plate to slide up and down, so as to press metal elbows of different sizes, so that the metal elbows will not have a deviation in the bending angle due to improper clamping during bending, thereby improving the stability of the device.
[0010] Preferably, there are two second movable plates, and the two second movable plates are symmetrically distributed inside the base, and the two second movable plates drive more stably, so that the cross-shaped pressing plate presses.
[0011] Preferably, there are two cross-shaped pressing plates, and grooves are provided at corresponding positions of the first baffle and the first disc, and the second baffle and the second disc for the two cross-shaped pressing plates. The two cross-shaped pressing plates move in the grooves to limit the cross-shaped pressing plates, better clamp the metal elbows, and improve the efficiency.
[0012] Preferably, there are two second limit blocks, and the two second limit blocks are symmetrically distributed on the tops of the first disc and the second disc, so that the bidirectional threaded rod can rotate inside the second limit block and the first limit block, improving the rotation efficiency.
[0013] The beneficial effects of the present utility model are as follows:
[0014] 1. By rotating the hexagonal rotating block, the bidirectional threaded rod inside the first limit block and the second limit block is driven to rotate, thereby driving the cross-shaped pressing plate to slide up and down, so as to press metal elbows of different sizes, so that the metal elbows will not have a deviation in the bending angle due to improper clamping during bending, thereby improving the clamping stability, avoiding the overall upward shift of the metal elbow during bending, which may cause a change in the bending angle of the metal elbow during bending, affecting the bending size and accuracy, and reducing the efficiency.

[0022] Please refer to Figures 2-3, in this embodiment, first limit blocks 22 are provided at the tops of the first baffle 5 and the second baffle 6. A bidirectional threaded rod 23 is rotatably connected inside the first limit block 22, and a second limit block 24 is rotatably connected to the outside of the bidirectional threaded rod 23. A hexagonal rotating block 21 is fixedly connected to the left side of the bidirectional threaded rod 23. The outside of the bidirectional threaded rod 23 is threadedly connected with a first hexagonal movable block 25 and a second hexagonal movable block 211. The outside of the first hexagonal movable block 25 is rotatably connected to a second movable plate 27, and the outside of the second hexagonal movable block 211 is rotatably connected to a first movable plate 26. Both the first movable plate 26 and the second movable plate 27 are rotatably connected to the outside of a fixed shaft 28. By rotating the hexagonal rotating block 21, the bidirectional threaded rod 23 inside the first limit block 22 and the second limit block 24 is driven to rotate, thereby driving the cruciform pressing plate 210 to slide up and down, so as to press metal elbows of different sizes, ensuring that the bending angle of the metal elbow will not deviate due to improper clamping during bending, thereby improving the stability of the device. There are two second movable plates 27, and the two second movable plates 27 are symmetrically distributed inside the base 29, and the two second movable plates 27 drive more stably, so that the cruciform pressing plate 210 presses. There are two cruciform pressing plates 210, and grooves are provided at corresponding positions of the first baffle 5 and the first disc 32, and the second baffle 6 and the second disc 33. The two cruciform pressing plates 210 move in the grooves to limit the cruciform pressing plates 210, better clamping the metal elbows and improving the efficiency.

[0023] Please refer to Figure 1 , Figure 4, in this embodiment, the bending assembly includes a bottom plate 31, the bottom plate 31 is fixedly connected to the top of the workbench 1, a first disc 32 is fixedly connected to the top of the bottom plate 31, a second disc 33 is fixedly connected to the top of the first disc 32, a motor 34 is fixedly connected to the top of the second disc 33, a rotating plate 35 is fixedly connected to the output shaft of the motor 34, a first fixing block 38 and a second fixing block 310 are slidably connected inside the rotating plate 35, a first bending shaft 36 is fixedly connected to the bottom of the first fixing block 38, a second bending shaft 37 is fixedly connected to the bottom of the second fixing block 310, a first bolt 39 is threadedly connected between the first fixing block 38 and the rotating plate 35, a second bolt 311 is threadedly connected between the second fixing block 310 and the rotating plate 35. By driving the rotating plate 35 with the motor 34, the first bending shaft 36 and the second bending shaft 37 can bend along the outer wall of the first disc 32 or the second disc 33. Since the diameters of the first disc 32 and the second disc 33 are different, the bending angles are also different, so that a device can bend with different angles, improving the practicability of the device. Grooves are provided at corresponding positions of the rotating plate 35 for the first fixing block 38 and the second fixing block 310, and the first fixing block 38 and the second fixing block 310 are movable in the grooves. A first baffle 5 is fixedly connected to the top of the bottom plate 31, and a second baffle 6 is fixedly connected to the top of the first disc 32. Through the grooves provided inside the rotating plate 35, the positions of the first fixing block 38 and the second fixing block 310 can drive the first bending shaft 36 and the second bending shaft 37 to be adjusted, and then fixed by the first bolt 39 and the second bolt 311, so that it can be adjusted according to elbows with different diameters, increasing the working efficiency.
[0024] When working, first rotate the hexagonal rotating block 21 to drive the bidirectional threaded rod 23 inside the first limiting block 22 and the second limiting block 24 to rotate, so that the first hexagonal movable block 25 and the second hexagonal movable block 211 slide outside the bidirectional threaded rod 23, thereby driving the base 29 outside the connecting fixed shaft 28 by the first movable plate 26 and the second movable plate 27 to slide up and down, and then driving the cross-shaped pressing plate 210 to slide up and down, so as to press metal elbows of different sizes, so that the metal elbows will not deviate in bending angle due to improper clamping during bending, thereby improving the stability of the device and improving work efficiency. Drive the rotating plate 35 through the motor 34, so that the first bending shaft 36 and the second bending shaft 37 can bend along the outer wall of the first disk 32 or the second disk 33. Because the diameters of the first disk 32 and the second disk 33 are different, the bending angles are also different, so that a device can bend different angles, improving the practicability of the device. Through the groove opened inside the rotating plate 35, the positions of the first fixing block 38 and the second fixing block 310 can drive the first bending shaft 36 and the second bending shaft 37 to be adjusted, and then fixed by the first bolt 39 and the second bolt 311, so that it can be adjusted according to elbows of different diameters, increasing work efficiency.
[0025] Through the above steps, rotate the hexagonal rotating block 21 to drive the bidirectional threaded rod 23 inside the first limiting block 22 and the second limiting block 24 to rotate, thereby driving the cross-shaped pressing plate 210 to slide up and down, so as to press metal elbows of different sizes, to solve the problem that the metal elbows will shift upward as a whole during bending, resulting in a change in the bending angle of the metal elbows during bending, affecting the size and precision of bending, and reducing efficiency.
