Referring to fig. 2, the wire welding apparatus 100 includes two clamping portions 1, a first heater 2 and a second heater 3, where the two clamping portions 1 are capable of moving relatively, and are used for clamping a first part to be welded and a second part to be welded, the first part to be welded includes a first end to be welded, the second part to be welded includes a second end to be welded, a cross-sectional area of the first end to be welded is smaller than that of the second end to be welded, the first heater 2 is used for heating the first end to be welded and the second end to be welded, so that the first end to be welded reaches a red heat non-softened state, and meanwhile, the second end to be welded reaches a softened state, and the second heater 3 is used for heating the softened second end to be welded when the red heat non-softened first end to be welded is inserted into the softened second end to be welded, so that the first end to be welded and the second end to be welded are welded.
It should be noted that, the above red-hot non-softened state refers to a state when the surface of the metal welding piece starts to be red after being heated to a certain temperature, and when the heating is continued to make the welding piece continuously raise the temperature, the hardness of the metal welding piece gradually decreases and then enters a softened state, according to different materials of the to-be-welded piece, the different materials are heated to the red-hot non-softened state and the different temperatures of the red-hot state, specifically, the materials of the to-be-welded piece can be selected, for example, after the iron wire reaches about 600 ℃, the iron wire starts to turn red and enters the red-hot non-softened state, when the heating is continued until the temperature reaches 700 ℃ to 800 ℃, the crystal structure of the iron wire changes, the original strength and hardness are lost, and the metal welding piece enters the softened state.
The wire welding device 100 provided by the invention comprises two clamping parts 1, a first heater 2 and a second heater 3, wherein in the welding process, the two clamping parts 1 respectively clamp the first to-be-welded piece and the second to-be-welded piece, the first heater 2 heats the first to-be-welded end and the second to-be-welded end so that the first to-be-welded piece reaches a red heat non-softened state, meanwhile, the second to-be-welded end reaches a softened state, the red heat non-softened second to-be-welded end is inserted into the softened second to-be-welded end through the relative movement of the two clamping parts 1, and then the second to-be-welded end softened through the second heater 3 is heated, so that the first to-be-welded end and the second to-be-welded end are welded, and thus, the proliferation characteristics of a welding part can be eliminated or controlled, the size of the welding part is stabilized, the appearance is ensured, and the welding cost and the technological difficulty of the thin wire welding piece are reduced.
Further, the first heater 2 includes an electromagnetic induction heater 21, the electromagnetic induction heater 21 includes a heating coil 211 for heating the first end to be welded and the second end to be welded, and the heating coil 211 may encircle the first end to be welded and the second end to be welded. In this way, the first end to be welded and the second end to be welded can be heated uniformly in the circumferential direction, and the power and the heating time of the electromagnetic induction heater 21 can be regulated to precisely control the heating of the first end to be welded and the second end to be welded to be in a red-hot non-softened state or a softened state, so that the subsequent welding work is facilitated.
The moving mode of the heating coil 211 is not specifically limited, and the heating coil 211 may be moved along a straight line or along an arc line, and only needs to be moved around the first to-be-welded end and the second to-be-welded end to heat, in this embodiment, the heating coil 211 may be moved along the extending axial direction of the first to-be-welded element and the second to-be-welded element, so as to heat around the first to-be-welded end and the second to-be-welded end, and thus, the lengths of the heated portions of the first to-be-welded end and the second to-be-welded end may be adjusted according to the requirement, and when the first to-be-welded element or the second to-be-welded element is coaxial, only needs to be moved along the direction of one axis of the first to-be-welded element or the second to-be-welded element, thereby improving the heating efficiency.
Further, the second heater 3 includes a laser welder 31, where the laser welder 31 includes a movably installed laser welding head 311 for heating the softened second end to be welded, so that when the first end to be welded, which is not softened by red heat, is inserted into the softened second end to be welded, the laser welding head 311 moves to the periphery of the softened second end to be welded, so that the first end to be welded and the second end to be welded are welded.
The method for movably mounting the laser welding head 311 is not particularly limited, and the laser welding head 311 only needs to be movable to be close to the softened second end to be welded, for example, in this embodiment, the laser welding head 311 is movably mounted up and down, so as to adjust the distance between the laser welding head 311 and the softened second end to be welded, so that the distance value is kept on the focal length value of the lens of the laser welding head 311, and welding precision and efficiency are improved.
Considering that the first end to be welded and the second end to be welded are columnar wires, in order to enable the first end to be welded to reach a red heat non-softened state and then to be inserted into the middle position of the end face of the second end to be welded, which is in a softened state, so as to improve the strength after welding is completed, in the embodiment, the two clamping parts 1 are coaxially opposite or oppositely movable, so that the first part to be welded and the second part to be welded can be clamped coaxially relatively movable in the welding process; after welding is completed, one clamping part 1 releases the clamping of the welded welding piece, and the two clamping parts 1 move along the coaxial opposite directions, so that the welded welding piece can be taken out conveniently.
In addition, the invention also provides a wire welding method, referring to fig. 3, fig. 3 is a schematic flow chart of an embodiment of the wire welding method provided by the invention;
the wire welding method comprises the following steps:
s10: providing a first part to be welded and a second part to be welded, wherein the first part to be welded comprises a first part to be welded and the second part to be welded comprises a second part to be welded, and the cross-sectional area of the first part to be welded is smaller than that of the second part to be welded.
It should be noted that, the cross-sectional areas of the first end to be welded and the second end to be welded are not particularly limited in the present invention, and only the heated first end to be welded can be inserted into the heated second end to be welded in a subsequent step.
In this embodiment, in order to enable the first end to be welded to be inserted into the second end to be welded, the first end to be welded and the second end to be welded are both cylindrical, and the ratio of the diameter of the first end to be welded to the diameter of the second end to be welded is k, where k is less than or equal to 0.7, for example, k may be 0.7, 0.6, 0.5, and when k is 0.7, the diameter of the first end to be welded is relatively large, after welding is completed, stable strength can be provided, and when k is 0.5, the diameter of the first end to be welded is relatively small, so that the difficulty in inserting the heated first end to be welded into the second end to be welded can be reduced.
S20: and heating the first end to be welded and the second end to be welded so that the first end to be welded reaches a red-hot non-softened state, and the second end to be welded reaches a softened state.
It should be noted that, the heating temperatures and heating times required for heating the end portion of the welding wire to reach the red-hot non-softened state and the softened state are different from each other due to different metal materials and different diameters, and in the invention, the welding wire is not particularly limited, and the first end to be welded is heated to reach the red-hot non-softened state, and the second end to be welded is heated to reach the softened state. In this embodiment, the electromagnetic induction heater 21 is used for heating, so that the power and the heating time of the electromagnetic induction heater 21 can be adjusted to accurately control the heating of the first end to be welded and the second end to be welded to be in a red-hot non-softened state or a softened state, so that the subsequent welding work is facilitated.
S30: inserting the first end to be welded in a red heat non-softened state into the softened second end to be welded.
It can be appreciated that the depth of the first end to be welded inserted into the second end to be welded should not be too large or too small, and when the insertion depth is too small, the overall strength of the welded part after the welding is completed may be affected, and the process difficulty of the insertion too deep is relatively large, and the structure of the second end to be welded may be affected. Specifically, in this embodiment, the diameter of the first end to be welded is D, and the depth of the first end to be welded inserted into the second end to be welded is L, where D is equal to or less than or equal to L is equal to 3D, for example, L may be D, 2D, 3D, and so on, preferably, l=2d, that is, the depth distance of the first end to be welded inserted into the second end to be welded is twice the diameter of the first end to be welded, so that the first end to be welded can be inserted into a sufficient depth while being convenient for insertion, so that the welded part as a whole has better strength after all welding procedures are completed.
S40: and heating the softened second end to be welded so that the second end to be welded and the first end to be welded are welded.
In this embodiment, the laser welder 31 is used to weld the softened second end to be welded by heating, it can be understood that when the diameters of the first end to be welded and the second end to be welded are too large or too small, the welding effect is affected, and thus the overall strength of the welded part after welding is directly affected, or the difficulty of processing is affected, so that the diameters of the first end to be welded and the second end to be welded are required to be within a certain range, in this embodiment, the diameter=d1 of the first end to be welded and the diameter of the second end to be welded is D2, wherein 0.3mm is equal to or less than d1 is equal to or less than d2 is equal to or less than 5mm, and in addition, when the diameters of D1 and D2 are required to meet the above range, the ratio k of D1 to D2 still needs to meet k is equal to or less than 0.7, for example, the D1 may be 0.3mm, the ratio k=0.6 of the two is required to be equal to 0.5 mm.
It is worth mentioning that D1 and D2 in the wire welding method provided by the present invention can be suitable for the situation that the diameter of the first end to be welded and the diameter of the second end to be welded are smaller than 0.5mm, and if the existing welding method is adopted, the proliferation feature is generated, and is difficult or impossible to eliminate by a machining mode, while by adopting the wire welding method provided by the present invention, the proliferation feature of the welding part can be eliminated or controlled, the size of the welding part is stabilized, the smoothness of the appearance is ensured, and the welding cost and the technological difficulty for eliminating the proliferation feature are reduced.

In addition, it can be understood that the insertion speed of the first end to be welded into the second end to be welded should not be too fast or too slow, when the insertion speed is too slow, the temperature of the heated first end to be welded or the heated second end to be welded is reduced along with time and is not in a red heat non-softened state or a softened state any more, so that the insertion efficiency is affected, when the first end to be welded is inserted too fast, the situation that the insertion process is just moved occurs, specifically, in the embodiment, the insertion speed of the first end to be welded into the second end to be welded is v, wherein v is equal to or less than 5mm/s and equal to or less than 20mm/s. For example, v may be 5mm/s, 10mm/s, 15mm/s, 20mm/s, etc., when the ratio k of the diameter of the first end to be welded to the diameter of the second end to be welded is large, such as k=0.7, the insertion may be performed at a speed of 5mm/s, so that the insertion process is smooth, and the offset during the insertion is avoided, and when the ratio k of the diameter of the first end to be welded to the diameter of the second end to be welded is small, such as k=0.3, the required insertion thrust is not too large, and therefore, the insertion speed of 15mm/s may be used to improve the welding efficiency.
