DETAILED DESCRIPTION

[0021] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings. Example

[0022] like Figure 1 , a wire feeding and straightening integrated device, including a wire straightening device 1 and a hyperbolic planetary gear wire feeding device 2 along the wire feeding direction, at least one set of reduction device 3 and at least one set of coupling device 4 are also arranged between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2, the wire straightening device 1 or the hyperbolic planetary gear wire feeding device 2 is driven to rotate by a power device 5.

[0023] The wire straightening device 1 is an offset rotating wire threading and straightening device, which can perform preliminary straightening of the wire during the rotation process. The hyperbolic planetary gear wire feeding device 2 is a rotating wire feeding device, which can not only realize wire feeding but also further straighten the wire during the rotation process. Since the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2 only need to rotate to work, a group of power devices 5 are used for driving, and a reduction device 3 and a coupling device 4 are used to connect the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2, so as to realize power transmission and change of speed ratio. The integrated wire feeding and straightening device has a compact structure, stable wire transportation, and good straightening effect, and is very suitable for wire transportation in welding, additive manufacturing and other fields.

[0024] like Figure 1 , Figure 2 The wire straightening device 1 is installed with at least two orifice plates 11 along the wire feeding direction. The orifice plates 11 are provided with straightening wire through holes 111. During the wire feeding process, the central axes of the straightening wire through holes 111 are staggered and offset relative to the rotation axis of the wire straightening device 1.

[0025] The wire passes through the staggered and offset straightening wire through holes 111 , and the wire straightening device 1 rotates under the drive of the power device 5 , thereby achieving straightening of the wire.

[0026] like Figure 1 , Figure 3 The hyperbolic planetary gear wire feeding device 2 includes a rotating frame 21 and a hyperbolic planetary gear 22; a hollow planetary gear accommodating area 211 is provided inside the rotating frame 21, and a wire feeding through hole 212 penetrating the rotating frame 21 is also provided at the rotation center of the rotating frame 21; two hyperbolic planetary gears 22 are provided, and the sides of the two hyperbolic planetary gears 22 are staggered and installed in the planetary gear accommodating area 211.

[0027] The rotating frame 21 and the hyperbolic planetary gear 22 form a hyperbolic planetary gear system. The rotation of the rotating frame 21 can cause the hyperbolic planetary gear 22 to rotate, thereby driving the wire to be transported along the axis of the wire feeding wire perforation 212.

[0028] like Figure 1 , Figure 3 The central axis of the wire feeding hole 212 is coaxial with the rotation axis of the wire straightening device 1.

[0029] The coaxiality of the central axis of the wire feeding hole 212 and the rotating axis of the wire straightening device 1 can ensure that the wire remains in a straight state after being straightened by the wire straightening device 1 and enters the hyperbolic planetary gear wire feeding device 2, thereby ensuring the final straightening effect.

[0030] The speed reducer 3 and the coupling 4 are both provided with through holes at their rotating shafts, and the through holes are coaxial with the central axis of the wire feeding hole 212 and the rotating shaft of the wire straightening device 1 .

[0031] The wire passes through the through holes at the rotation shafts of the speed reducer 3 and the coupling device 4, ensuring that the wire always remains in a straight line after being straightened by the wire straightening device 1.

[0032] like Figure 1 The power device 5 is a ring motor and is directly connected to the wire straightening device 1 .

[0033] The use of a ring motor in the power device 5 can make the structure of the wire feeding and straightening integrated device more compact.

[0034] like Figure 1 , Figure 3 The angle between the rotating shaft of the hyperbolic planetary gear 22 and the axis of the wire feeding hole 212 is 0° to 90°.

[0035] The larger the angle between the rotating shaft of the hyperbolic planetary wheel 22 and the axis of the wire feeding wire hole 212, the faster the wire feeding speed. However, if the angle is too large, it will easily cause the hyperbolic planetary wheel 22 to slip on the wire surface. Therefore, the wire feeding effect is better when the angle is close to 45°.

[0036] The reduction ratio of the reduction device 3 is positively correlated with the included angle.

[0037] The smaller the angle between the rotating shaft of the hyperbolic planetary gear 22 and the axis of the wire feeding wire through hole 212, the greater the rotation speed of the hyperbolic planetary gear 22 is required to ensure the same wire feeding speed. The input end of the reduction device 3 is connected to the wire straightening device 1, and the output end is connected to the hyperbolic planetary gear wire feeding device 2. When the input end rotation speed remains unchanged, the greater the reduction ratio, the smaller the output end rotation speed, so the reduction ratio is proportional to the angle. Example

[0038] like Figure 4 , Figure 5 The wire feeding and straightening integrated device comprises a wire straightening device 1 and a hyperbolic planetary gear wire feeding device 2 along the wire feeding direction, and a speed reduction device 3 or a coupling device 4 is also arranged between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2.

[0039] The wire straightening device 1 is an offset rotating wire threading and straightening device, which can perform preliminary straightening on the wire during the rotation process. The hyperbolic planetary gear wire feeding device 2 is a rotating wire feeding device, which can not only realize wire feeding but also further straighten the wire during the rotation process. The reduction device 3 or the coupling device 4 is used to realize power transmission between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2. Only the reduction device 3 or the coupling device 4 is installed between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2, which can further reduce the volume of the wire feeding and straightening integrated device and enhance the compactness. When only the coupling device 4 is installed between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2, the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2 have the same rotation speed, and the relationship between their rotation speed and the wire feeding speed is adjusted by adjusting the angle between the hyperbolic planetary gear and the rotating shaft in the hyperbolic planetary gear wire feeding device 2 to meet the effects of wire feeding and straightening. Example

[0040] like Figure 6 The wire feeding and straightening integrated device comprises a wire straightening device 1 and a hyperbolic planetary gear wire feeding device 2 which can rotate coaxially along the wire feeding direction, and the wire outlet end of the wire straightening device 1 is connected with the wire inlet end of the hyperbolic planetary gear wire feeding device 2.

[0041] The wire straightening device 1 is an offset rotating wire threading and straightening device, which can perform preliminary straightening of the wire during the rotation process. The hyperbolic planetary gear wire feeding device 2 is a rotating wire feeding device, which can not only realize wire feeding but also further straighten the wire during the rotation process. The reduction device 3 or the coupling device 4 is used to realize the power transmission between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2. The connection between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2 can further reduce the volume of the wire feeding and straightening integrated device and enhance its compactness. The wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2 have the same rotation speed, and the relationship between their rotation speed and the wire feeding speed is adjusted by adjusting the angle between the hyperbolic planetary gear and the rotating shaft in the hyperbolic planetary gear wire feeding device 2 to meet the wire feeding and straightening effects.

[0042] A wire feeding and straightening method, used in the integrated wire feeding and straightening device of Example 1, comprises the following method: the wire passes through the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2 in sequence, the power device 5 drives the hyperbolic planetary gear wire feeding device 2 to rotate at the required wire feeding speed, the wire straightening device 1 selects the rotation speed required for its straightening according to the required wire feeding speed, and the reduction device 3 selects the corresponding reduction ratio according to the rotation speed ratio between the hyperbolic planetary gear wire feeding device 2 and the wire straightening device 1.

[0043] The wire also passes through the reduction device 3 and the coupling device 4 between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2. The order of the reduction device 3 and the coupling device 4 can be interchanged. When the reduction ratio between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2 is relatively high, the reduction device 3 can be decelerated by multiple groups in series. The above reduction devices 3 are all fixed reduction ratios. In the case where the speed variation range of the wire feeding of the hyperbolic planetary gear wire feeding device 2 is large, the reduction device 3 can also choose to use a reduction device with a variable reduction ratio to ensure that the speed change rate of the wire straightening device 1 is lower than the speed change rate of the hyperbolic planetary gear wire feeding device 2, so that it can be stable for straightening the wire and will not get stuck.

[0044] A wire feeding and straightening method, used in the wire feeding and straightening integrated device of embodiment 2, comprises the following method: Method 1: In a state where a reduction device 3 is provided between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2, the wire passes through the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2 in sequence, the power device drives the hyperbolic planetary gear wire feeding device 2 to rotate at the required wire feeding speed, the wire straightening device 1 selects the speed required for its straightening according to the required wire feeding speed, and the reduction device 3 selects the corresponding reduction ratio according to the speed ratio between the hyperbolic planetary gear wire feeding device 2 and the wire straightening device 1; Method 2: When a coupling device 4 is provided between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2, the wire passes through the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2 in sequence, the power device drives the hyperbolic planetary gear wire feeding device 2 to rotate at the required wire feeding speed, the wire straightening device 1 selects the rotation speed required for its straightening according to the required wire feeding speed, and the hyperbolic planetary gear wire feeding device 2 determines the angle between the hyperbolic planetary gear shaft and the wire feeding direction according to the wire feeding speed and the rotation speed.

[0045] The wire also passes through the speed reduction device 3 or the coupling device 4 between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2. When the speed reduction ratio between the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2 is relatively high, the speed reduction device 3 can be decelerated by multiple groups in series. The above speed reduction devices 3 are all fixed speed reduction ratios. In the case where the speed variation range of the wire feeding of the hyperbolic planetary gear wire feeding device 2 is large, the speed reduction device 3 can also choose to use a speed reduction device with a variable speed reduction ratio to ensure that the speed change rate of the wire straightening device 1 is lower than the speed change rate of the hyperbolic planetary gear wire feeding device 2, so that it can stabilize the straightening of the wire and will not get stuck.

[0046] A wire feeding and straightening method, used in the integrated wire feeding and straightening device of Example 3, comprises the following method: the wire passes through the wire straightening device 1 and the hyperbolic planetary gear wire feeding device 2 in sequence, the power device drives the hyperbolic planetary gear wire feeding device 2 to rotate at the required wire feeding speed, the wire straightening device 1 selects the rotation speed required for its straightening according to the required wire feeding speed, and the hyperbolic planetary gear wire feeding device 2 determines the angle between the hyperbolic planetary gear shaft and the wire feeding direction according to the wire feeding speed and the rotation speed.
