Description

Technical Field

[0001] This invention relates to the field of welding equipment, and in particular to an aluminum flexible joint welding machine. Background Technology

[0002] Most welding machines used in the processing of aluminum flexible connectors employ molecular diffusion welding, a novel diffusion method. This method involves bonding metal objects by causing molecular diffusion between their contact surfaces under specific temperature and pressure conditions. A molecular diffusion welding machine consists of a main unit and a control unit. Its primary function is to achieve diffusion welding between material molecules. This equipment mainly produces busbar expansion joints and flexible conductive strips urgently needed in the power, chemical, and metallurgical industries. It can perform diffusion welding between flexible busbars, between flexible and rigid busbars, and between rigid busbars.

[0003] Existing aluminum flexible connector welding machines, during pressure welding, often use a specified welding pressure due to the light weight and low tensile and bending strength of aluminum strips. Because of this, the welding pressure can easily cause deformation of the aluminum strips if the welding pressure is too high, affecting the regularity of the strip edges and further impacting the processing quality of the aluminum flexible connector. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an aluminum flexible joint welding machine.

[0005] To achieve the above objectives, this application provides the following technical solution: an aluminum flexible joint welding machine, including a frame, a control box installed on the top of the frame, a base and a beam plate arranged on the top of the frame, the beam plate being located directly above the base, the opposite sides of the base and the beam plate being connected by multiple connecting rods to form a space that can accommodate aluminum strips passing through, and a lifting pressure welding mechanism arranged on the base and the beam plate.

[0006] The base is provided with an adjustable limiting structure at its top. The limiting structure extends to the lifting and pressing welding mechanism and can movably contact the aluminum strip during the pressing welding process. The lifting and pressing welding mechanism is provided with an auxiliary structure that is adapted to the limiting structure for fully positioning the stacked aluminum strip.

[0007] Furthermore, the lifting and welding mechanism includes a cylinder mounted on a beam plate, a conveyor plate mounted on the output shaft of the cylinder, a through hole adapted to the docking rod on the surface of the conveyor plate, a coil heating seat mounted below the conveyor plate, and a graphite pressure plate mounted below the coil heating seat.

[0008] A second coil heating seat is provided on the top of the base, and a second graphite pressure plate is installed above the second coil heating seat. The interface of the first coil heating seat and the second coil heating seat is electrically connected to the control box through a conductive line.

[0009] Furthermore, the limiting structure includes an upper limit seat installed on the base. An extension rod is horizontally installed on the inner side wall of the limiting seat. A guide seat is slidably connected to the outer surface of the extension rod. A first support arm is detachably installed on the side of the guide seat near the second graphite pressure plate. The first support arm extends above the second graphite pressure plate and can abut against one side of the aluminum strip during the overlapping welding process. Fasteners are provided on the side of the guide seat.

[0010] Furthermore, the fastener includes a detachable limiting collar mounted on the guide seat. The inner wall of the limiting collar is connected to a bidirectional screw via an annular slide rail. Clamping seat one and clamping seat two are respectively installed on the forward and reverse threads of the surface of the bidirectional screw. Each of the clamping seat one and clamping seat two has a channel adapted to the extension rod on its opposite side, which can movably clamp the extension rod to increase frictional resistance.

[0011] Furthermore, a barrier plate is fixed to the top of the second graphite pressure plate, and the surface of the barrier plate abuts against the end of the first support arm. The two are distributed vertically above the second graphite pressure plate.

[0012] Furthermore, the auxiliary structure includes a second support arm disposed above the second graphite pressure plate. The second support arm is U-shaped, and a hand handle is fixed to the inner side of the two symmetrical support plates of the second support arm. A guide bar is detachably installed on the second graphite pressure plate. When the guide bar is installed on the second graphite pressure plate, its side faces the side of the barrier plate. The relative space between the guide bar and the barrier plate forms a channel for the second support arm to slide. A locking element is provided on the hand handle.

[0013] Furthermore, the locking element includes a sliding strip sleeved on the surface of the hand handle, and a knob is connected to the sliding strip via an annular slide rail. The surface of the guide strip has a groove that matches the knob.

[0014] A pressure strip is fixedly connected to the surface of the handheld lever. The opposite sides of the pressure strip and the sliding strip are connected by a return spring. When the sliding strip is pressed, the return spring contracts under the pressure of the sliding strip until the knob disengages from the groove.

[0015] Furthermore, the inner bottom arm of the limiting seat is provided with multiple sets of rollers, which are adapted to the bottom recessed part of the guide seat.

[0016] In summary, the technical effects and advantages of this invention are as follows:

[0017] This invention features a limiting structure and an auxiliary structure that can be adjusted to contact the lifting and pressing welding mechanism, thus forming a pressing welding space that restricts the specifications of the aluminum strip. During the pressing welding process, it avoids excessive welding force that could cause deformation of the copper strip, ensuring the smoothness and quality of the pressing weld area and resulting in higher processing precision. It can also adapt to aluminum strips of different specifications.

[0018] Before the pressure welding work is carried out, multiple overlapping aluminum strips can be aligned and placed on the inside of the barrier plate and the second arm, which effectively improves the accuracy of the mating surfaces of the multiple overlapping aluminum strips. As the limiting structure and the aluminum strips are mated, the accuracy of the aluminum flexible connection structure after pressure welding can be further guaranteed during the pressure welding process.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Reference Figure 1 , Figure 2 and Figure 4 The aluminum flexible joint welding machine shown includes a frame 1, a control box 2 mounted on top of the frame 1, a base 3 and a beam plate 4 positioned above the frame 1, with the beam plate 4 directly above the base 3. The base 3 and beam plate 4 are connected on opposite sides by multiple connecting rods 5, forming a space that allows aluminum strips to pass through. A lifting and pressure welding mechanism is installed on the base 3 and beam plate 4. This lifting and pressure welding mechanism can perform pressure welding on the stacked aluminum strips.

[0029] The top of the base 3 is equipped with an adjustable limiting structure that extends to the lifting and pressing welding mechanism. This structure can move and contact the aluminum strip during the pressing welding process. The lifting and pressing welding mechanism is equipped with an auxiliary structure that is compatible with the limiting structure. This structure is used to fully position and limit the stacked aluminum strips, thus regulating the aluminum strips and ensuring the accuracy of the joint of the stacked aluminum strips for subsequent lifting and pressing welding work.

[0030] like Figure 4 As shown, the lifting and welding mechanism includes a cylinder 6 mounted on a beam plate 4, a conveyor plate 7 mounted on the output shaft of the cylinder 6, a through hole adapted to the docking rod 5 on the surface of the conveyor plate 7, a coil heating seat 8 mounted below the conveyor plate 7, and a graphite pressure plate 9 mounted below the coil heating seat 8.

[0031] A coil heating seat 2 10 is provided on the top of the base 3, and a graphite pressure plate 2 11 is installed above the coil heating seat 2 10. The interface of the coil heating seat 1 8 and the coil heating seat 2 10 is electrically connected to the control box 2 through a conductive line.

[0032] In the actual use of the lifting and pressure welding mechanism, the aluminum strip is placed above the graphite pressure plate 11. The control box 2 can be an industrial PLC control module, which can drive the coil heating seat 8 and the coil heating seat 10 to be energized and heated. Subsequently, the control box 2 can operate the cylinder 6 to operate, and the conveyor plate 7, the coil heating seat 8 and the graphite pressure plate 9 descend to contact the aluminum strip and carry out high-temperature pressure welding.

[0033] like Figure 2 , Figure 5As shown, the limiting structure includes an upper limit seat 13 installed on the base 3. An extension rod 14 is horizontally installed on the inner side wall of the limiting seat 13. A guide seat 15 is slidably connected to the outer surface of the extension rod 14. A first support arm 16 is detachably installed on the side of the guide seat 15 near the graphite pressure plate 11. The first support arm 16 extends above the graphite pressure plate 11 and can abut against one side of the aluminum strip during the overlapping welding process as the guide seat 15 slides.

[0034] By contacting the first arm 16, whose position can be adjusted with the guide seat 15, with the aluminum strip, a pressure welding space that restricts the specifications of the aluminum strip can be formed. During the pressure welding process, excessive pressure welding force is avoided to prevent deformation of the copper strip, ensuring the smoothness and quality of the pressure welding part, and resulting in higher processing precision.

[0035] It is worth mentioning that the position of the first arm 16 on the graphite pressure plate 11 is adjustable to accommodate aluminum strips of different specifications. Fasteners are provided on the side of the guide seat 15 to ensure its stability when moving to the designated position. By placing the fasteners in front of the graphite pressure plate 11, operator convenience is enhanced, improving safety during operation.

[0036] like Figure 5 As shown, the fastener includes a detachable limiting collar 20 mounted on the guide seat 15. The inner wall of the limiting collar 20 is connected to a bidirectional screw 19 via an annular slide rail. Clamping seats 17 and 18 are respectively installed on the forward and reverse threads of the surface of the bidirectional screw 19. The opposite sides of clamping seats 17 and 18 are provided with channels that are compatible with the extension rod 14. When the guide seat 15, clamping seats 17 and 18 slide to the designated position according to the actual pressure welding process, the bidirectional screw 19 can be rotated. The forward and reverse thread forces can drive clamping seats 17 and 18 to clamp the extension rod 14, increase frictional resistance, and prevent the guide seat 15, clamping seats 17 and 18 from sliding easily, thus improving the stability of the first arm 16 on the graphite pressure plate 211.

[0037] like Figure 4 As shown, a baffle plate 12 is fixed to the top of the graphite pressure plate 11. The surface of the baffle plate 12 abuts against the end of the first support arm 16, and the two are vertically distributed above the graphite pressure plate 11. The purpose of providing the baffle plate 12 is to protect the end of the aluminum strip during the pressure welding process. Combined with the limiting structure and auxiliary structure, it can limit the specifications of the aluminum strip during the pressure welding process and prevent the end of the stacked aluminum strip from deforming due to excessive pressure.

[0038] Example 2: As Figure 2 , Figure 3 and Figure 4As shown, the auxiliary structure includes a second support arm 21 disposed above the graphite pressure plate 11. The second support arm 21 is U-shaped, and a hand handle 23 is fixed to the inner side of the two symmetrical support plates of the second support arm 21. A guide strip 22 is detachably installed on the graphite pressure plate 11. When the guide strip 22 is installed on the graphite pressure plate 11, its side faces the side of the barrier plate 12. The relative space between the guide strip 22 and the barrier plate 12 forms a channel for the second support arm 21 to slide. A locking element is provided on the hand handle 23.

[0039] The second arm 21 and the hand lever 23 can slide synchronously to the bottom of the graphite pressure plate 11, contacting one side of the stacked aluminum strip. During the pressure welding process of the aluminum strip, the second arm 21 does not need to be adjusted repeatedly, and it remains above the graphite pressure plate 11 throughout the process. Before the pressure welding, multiple stacked aluminum strips can be easily aligned and placed inside the barrier plate 12 and the second arm 21, effectively improving the accuracy of the mating surfaces of the stacked aluminum strips. As the limiting structure mates with the aluminum strip, the accuracy of the welded aluminum flexible connection structure is further ensured during the pressure welding process.

[0040] like Figure 6 As shown, the locking component includes a sliding strip 24 sleeved on the surface of the handgrip 23. A knob 25 is connected to the sliding strip 24 via an annular slide rail. A groove matching the knob 25 is formed on the surface of the guide strip 22. When the second arm 21 slides to the designated position on the graphite pressure plate 11, the knob 25 can be controlled to rotate until the knob 25 aligns with the groove, ensuring the stability of the second arm 21 during movement. Furthermore, it effectively prevents the second arm 21 from shifting during sliding.

[0041] A pressure strip 26 is fixedly connected to the surface of the hand lever 23. The opposite sides of the pressure strip 26 and the sliding strip 24 are connected by a return spring 27. After the aluminum strip welding is completed and the limiting structure is disengaged from the surface of the graphite pressure plate 21, the sliding strip 24 can be pressed. The return spring 27 contracts under the pressure of the sliding strip 24 until the knob 25 disengages from the groove. Rotating the knob 25 returns it to its original position, allowing the hand lever 23 to be manipulated to smoothly push the second arm 21 backward, fully exposing the graphite pressure plate 21 for cleaning.

[0042] like Figure 5 As shown, multiple sets of rollers 28 are provided on the inner bottom arm of the limiting seat 13. The rollers 28 are adapted to the bottom recessed part of the guide seat 15. The purpose of providing rollers 28 is to improve the smoothness of the guide seat 15 during the sliding process and avoid the guide seat 15 from getting stuck during the sliding process, so as to accurately adjust the relative position of the guide seat 15 in the limiting seat 13.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
