Description

Technical Field

[0001] The invention belongs to the technical field of welding, and more specifically, particularly relates to a hardware spring piece welding wire device. Background Art

[0002] Metal shrapnel welding is a process of connecting metal shrapnel with other electrical components or wires. It is often used in situations where electrical connection is required. Generally, the metal shrapnel and the wire are placed on a supporting fixture so that the ends of the metal shrapnel and the wire are in contact. A hot melt welding machine is used to weld the contact parts to connect the metal shrapnel and the wire.

[0003] The existing hardware shrapnel welding has the following disadvantages:

[0004] 1. When the existing hardware shrapnel and wire are welded, they are placed on the supporting fixture. The melted metal will adhere to the fixture during welding, which may cause the hardware shrapnel and wire to stick to the fixture. After the hardware shrapnel and wire are removed, there may still be metal residue on the fixture. Long-term use will cause the fixture to deform and need to be cleaned or replaced regularly, which consumes manpower and material resources, otherwise it will affect the welding quality;

[0005] 2. When welding the existing hardware shrapnel and wire, the welding gun generally contacts the hardware shrapnel and wire from top to bottom for welding. Generally, only the upper part of the contact end of the hardware shrapnel and the wire is welded, and the lower section or side end does not contact the welding gun, which may cause uneven welding and loose welding, affecting the stability between the hardware shrapnel and the wire in the later stage and affecting the use.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In the present invention, by providing a C-shaped clamp and an arc-shaped clamp rod in cooperation, the metal spring piece and the wire can be fixed between the C-shaped clamp and the arc-shaped clamp rod respectively, without using an additional supporting fixture, so that the contact ends of the metal spring piece and the wire are in an overhead position, avoiding the phenomenon that the molten metal adheres to the supporting fixture during hot-melt welding, avoiding the subsequent situation that the metal spring piece and the wire may stick to the fixture, affecting the welding efficiency and aesthetics, and avoiding additional cleaning or replacement of the fixture, thereby improving the convenience of welding work.

[0013] In the present invention, a motor, a first rotating shaft, a transmission rod and a second rotating shaft are provided to cooperate with each other. When the metal spring piece and the wire are welded, by starting the motor, with the cooperation of a plurality of gears, the adjusting plate can be driven to rotate while the C-shaped clamp rotates, so that the metal spring piece and the wire rotate at the same time during welding, and then the entire circumferential end of the metal spring piece and the contact end of the wire is welded, thereby ensuring the uniformity and aesthetics of the welding, making the metal spring piece and the wire more firmly connected after welding, and improving the stability of the welding.

When the connecting plate does not need to rotate, the limiting rod is clamped on the inner wall of the second circular groove to limit the round shaft and the connecting plate.

The stability of the fixing mechanisms on both sides during welding is ensured by the clamping mechanism, which makes the welding beautiful and firm, and also facilitates the user to disassemble the metal spring pieces and wires that have been welded below, thereby achieving good use effect.

[0015] In the present invention, by providing two upper and lower fixing mechanisms and connecting plates that can work alternately, the hardware spring pieces and wires can be disassembled and assembled on the other set of fixing mechanisms while welding is being performed on one set of fixing mechanisms, thereby reducing the downtime during welding, improving the overall production efficiency, and ensuring the continuous welding operation without waiting for the cooling or replacement of the hardware spring pieces and wires.

[0016] In the present invention, by providing a fixing mechanism that can alternately perform welding on the left and right, the welding assembly can be kept in a continuous working state. When one group of fixing mechanisms completes welding, the other group of fixing mechanisms can be adjusted to start welding, thereby reducing the waiting time of the welding assembly and improving the utilization rate of the welding assembly. When the welding assembly is working continuously, its heat can be more effectively transferred to the welding point, reducing the heat loss caused by repeatedly starting and stopping the welding assembly, thereby improving the welding efficiency and stability, and avoiding frequent heating and cooling of the welding assembly during use, reducing the risk of damage to the welding assembly and extending its service life.

[0033] Working principle:

[0034] The first step is that the metal shrapnel welding wire is a process for connecting the metal shrapnel with other electrical components or wires. When welding the metal shrapnel and the wire, the metal shrapnel can be fixed in the C-shaped clamp 7, the wire can be fixed between the two arc-shaped clamp rods 85, the end of the wire and the end of the metal shrapnel can be fitted together, the motor 3 is started to drive the C-shaped clamp 7 and the arc-shaped clamp rod 85 to rotate, drive the metal shrapnel and the wire to rotate, and at the same time start the welding assembly 21 to perform hot-melt welding on the metal shrapnel and then the wire. After the welding is completed, the welding assembly 21 and the motor 3 can be closed, and the rotatable connecting plate 9 can drive the upper and lower sets of fixing mechanisms 5 to swap positions, weld the next set of metal shrapnel to be welded, and disassemble the metal shrapnel located at the bottom that has been welded;

[0035] In the second step, before the user welds the hardware spring piece, the user needs to fix the hardware spring piece and the wire respectively. The user can insert the hardware spring piece between the two clamping plates 74. The ends of the two clamping plates 74 are arc-shaped, which is convenient for the direct insertion of the hardware spring piece. After inserting the hardware spring piece, the third spring 75 will push the two clamping plates 74 close to each other to fix the hardware spring piece. The user can also fix the wire. The user can press the wire downward from the top of the two arc-shaped clamping rods 85. The top of the two arc-shaped clamping rods 85 is also arc-shaped, which is convenient for directly installing the wire downward. After pressing the wire between the two arc-shaped clamping rods 85, the fourth spring 87 will rebound and pull the two arc-shaped clamping rods 85 close to each other through the T-shaped slider 86 and the fourth spring 87, thereby fixing the wire. After the hardware spring piece and the wire are fixed, the positions of the two can also be fine-tuned according to the welding needs, so that the ends of the hardware spring piece and the wire are in contact, which is convenient for subsequent welding.

[0036] In the third step, after completing the fixing of the above-mentioned parts, the user can start the motor 3. The motor 3 starts to drive the fixing column 31 to rotate. The fixing column 31 rotates through the two first telescopic rods 34 to drive the side plate 32 to rotate. The side plate 32 rotates to drive the two plug rods 36 to rotate. The two plug rods 36 are both located on the inner wall of the rectangular slot 72. The rotation of the two plug rods 36 will also drive the first rotating shaft 71 to rotate. The rotation of the first rotating shaft 71 will drive the C-shaped clamp 7 to rotate. The rotation of the first rotating shaft 71 will also drive the seventh conical tooth 73 to rotate. The rotation of the seventh conical tooth 73 drives the first connecting shaft 57 to rotate through the third conical tooth 58. The rotation of the first connecting shaft 57 drives the second conical tooth 56 to rotate. The second conical tooth 56 rotates through the first conical tooth 53 to drive the fourth conical tooth 61 on the transmission rod 51 to rotate. 1 rotates through the fifth conical tooth 65 to drive the sixth conical tooth 66 on the second connecting shaft 64 to rotate, and the rotation of the sixth conical tooth 66 will drive the adjustment plate 8 on the second rotating shaft 82 to rotate simultaneously through the eighth conical tooth 83, and the rotation of the adjustment plate 8 will simultaneously drive the two arc clamping rods 85 to rotate through the T-shaped slider 86 and the L-shaped side rod 84, thereby driving the wire to rotate, thereby realizing the simultaneous rotation of the wire and the hardware spring sheet. When the hardware spring sheet and the wire rotate, the user can start the welding assembly 21 to drive the welding head of the welding assembly 21 close to the contact part of the hardware spring sheet and the wire, and start the welding assembly 21 to perform hot-melt welding on the hardware spring sheet and the wire. At the same time, the hardware spring sheet and the wire are rotating, so that the entire circumference of the contact end of the hardware spring sheet and the wire can be welded. After the welding is completed, the user can turn off the welding assembly 21 and the motor 3;

[0037] The device is provided with a C-shaped clamp 7 and an arc-shaped clamp rod 85 to cooperate with each other, so that the metal spring piece and the wire can be fixed between the C-shaped clamp 7 and the arc-shaped clamp rod 85 respectively, without using an additional supporting fixture, so that the contact ends of the metal spring piece and the wire are in an overhead position, avoiding the phenomenon that the molten metal adheres to the supporting fixture during hot-melt welding, avoiding the subsequent situation that the metal spring piece and the wire may stick to the fixture, affecting the welding efficiency and aesthetics, and avoiding additional cleaning or replacement of the fixture, thereby improving the convenience of welding work;

[0038] The device is provided with a motor 3, a first rotating shaft 71, a transmission rod 51 and a second rotating shaft 82, and when the metal spring piece and the wire are welded, by starting the motor 3, with the cooperation of a plurality of gears, the adjusting plate 8 can be driven to rotate while the C-shaped clamp 7 rotates, so that the metal spring piece and the wire rotate at the same time during welding, and then the entire circumferential end of the metal spring piece and the contact end of the wire is welded, so as to ensure the uniformity and aesthetics of welding, so that the metal spring piece and the wire after welding are more firmly connected, and the stability of welding is improved;

[0039] In the fourth step, at the beginning of the first welding work, the user can fix the hardware spring pieces and wires to be welded next time on the fixing mechanism 5 located at the bottom, and the method is the same as the method described in the second step. After the first welding work is completed, the user can pull the pull plate 35, and the pull plate 35 moves to drive the two plug rods 36 to leave the inner side walls of the two third telescopic rods 76 located at the top. The user can pull the arc plate 43 to drive the limit rod 45 to leave the inner side walls of the two second circular grooves 12. The user can rotate the arc plate 43, and the rotation of the arc plate 43 drives the circular shaft 4 to rotate through the second telescopic rod 42, and the rotation of the circular shaft 4 drives the connecting plate 9 to rotate. At this time, the upper and lower sets of fixing mechanisms 5 will be swapped. When the end of the first rotating shaft 71 contacts the end of the plug rod 36 with the beveled surface, it will push the plug rod 36 to move, and the movement of the plug rod 36 will drive the other plug rod 36 to move at the same time through the side plate 32. After the rectangular slot 72 on the first rotating shaft 71 below and the two plug rods 36 are completely overlapped, the first spring 33 will push the side plate 32 to drive the two plug rods 36 to be completely inserted into the inner wall of the rectangular slot 72. At this time, the connecting plate 9 rotates 180 degrees to complete the position swap of the upper and lower fixing mechanisms 5. The user can loosen the arc plate 43, and the second spring 41 will pull the limiting rod 45 on the arc plate 43 to enter the second circular groove 12 again to limit the connecting plate 9 on the circular shaft 4;

[0040] The user sets the arc plate 43, the limiting rod 45, the round shaft 4 and the connecting plate 9 to cooperate with each other. When the connecting plate 9 does not need to rotate, the limiting rod 45 is clamped on the inner wall of the second circular groove 12 to limit the round shaft 4 and the connecting plate 9, so as to avoid the user accidentally touching the connecting plate 9 during the welding work, causing the fixing mechanisms 5 on both sides to shake, thereby affecting the welding effect. The clamping mechanism ensures the stability of the fixing mechanisms 5 on both sides during welding, which is convenient for the user to disassemble the metal springs and wires welded below, and the use effect is good.

[0041] Step 5. After the fixing mechanisms 5 at the upper and lower ends are swapped after the step 4, the user can now swap the fixing mechanisms 5 at the upper end to perform welding, disassemble the metal shrapnel and wires that have been welded at the lower end, and fix the next set of metal shrapnel and wires that need to be welded, thereby completing the disassembly and assembly of the metal shrapnel and wires while welding.

[0042] The device is provided with two upper and lower fixing mechanisms 5 and connecting plates 9 that can work alternately. When one set of fixing mechanisms 5 is welding, the hardware spring pieces and wires can be disassembled and assembled on the other set of fixing mechanisms 5, thereby reducing the downtime during welding, improving the overall production efficiency, and ensuring the continuous welding operation without waiting for the cooling or replacement of the hardware spring pieces and wires.

[0043] The device is provided with left and right fixing mechanisms 5 that can alternately perform welding, so that the welding assembly 21 can maintain a continuous working state. When one group of fixing mechanisms 5 completes welding, the other group of fixing mechanisms 5 can be adjusted to start welding, thereby reducing the waiting time of the welding assembly 21 and improving the utilization rate of the welding assembly 21. When the welding assembly 21 is working continuously, its heat can be more effectively transferred to the welding point, reducing the heat loss caused by repeatedly starting and stopping the welding assembly 21, thereby improving the welding efficiency and stability, and avoiding frequent heating and cooling of the welding assembly 21 when in use, reducing the risk of damage to the welding assembly 21 and extending its service life.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
