Description

Technical Field

[0001] The present invention relates to the technical field of copper bar welding, and particularly relates to a copper bar welding device. Background Art

[0002] Copper bar welding is mainly based on the principle of hot fusion of metals. During the welding process, the local area of the copper bar is heated to reach the melting or plastic state, and then the contact surfaces are melted and pressed together to form a metallurgical bond. Different welding methods have different heating methods and heat sources.

[0003] Due to the high thermal conductivity of copper, heat is easily dissipated during the welding process, and it is necessary to strictly control the welding temperature and welding speed. In the power system, copper bars, as conductive materials, need to be welded into busbars of various shapes and sizes; in the electrical system, copper bars, as the connection parts of the circuit, need to be welded to achieve circuit connection and transmission; in the refrigeration system, copper bars, as the materials of heat exchangers, need to be welded into heat exchangers of various shapes.

The present invention provides a high-frequency welding machine for soft copper bar production that can limit the two ends while pushing the two ends of the soft copper bar to move inward to prevent warping and improve the welding quality of the soft copper bar. A high-frequency welding machine for soft copper bar production includes a water tank and support plates fixedly connected to both sides of the water tank, and a welding machine is fixedly connected to the support plates. In the present invention, the conveyor is started to drive the soft copper bar to move rightward to directly below the welding machine, the pressing blocks contact the two ends of the soft copper bar, and then the welding machine is started to move downward, so that the positioning plate first centers and positions the soft copper bar, and then the pushing plate moves inward to squeeze the two ends of the soft copper bar, making the middle part of the soft copper bar bulge downward in an arc shape. During the squeezing process, the pressing blocks press and limit the two ends of the soft copper bar to prevent the end of the soft copper bar from warping and affecting the welding quality, thereby improving the welding quality of the soft copper bar.

[0005] However, when welding the copper bar, this patent cannot effectively control the temperature during the copper bar welding process, cannot keep the copper bar in a comfortable welding range, resulting in problems such as over-welding of the copper bar.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above defects. Summary of the Invention

[0007] The purpose of the present invention is to provide a copper bar welding device that can effectively solve the above technical problems.

[0032] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "center", "transverse", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as limiting the protection scope of the present invention. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may also be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0034] As Figures 1 to 8 shown, a copper bar welding device of the present invention includes a driving assembly 1 that drives the welding head to move back and forth, a lifting assembly 2 that adjusts the height of the welding head, a cooling assembly 3 that cools the welded copper bar, a moving assembly 5 that drives the water source to move, and a limiting assembly 6 that limits the position of the conveyed water flow.

[0035] The high thermal conductivity of copper makes it easy for heat to dissipate during the welding process, so it is necessary to strictly control the welding temperature and welding speed. In the power system, as a conductive material, copper bars need to be welded into busbars of various shapes and sizes; in the electrical system, as a connection part of the circuit, copper bars need to be welded to achieve circuit connection and transmission; in the refrigeration system, as a material for heat exchangers, copper bars need to be welded into heat exchangers of various shapes.

[0036] The driving assembly 1 includes a first motor 11, a first screw rod 13 fixedly installed at the output end of the first motor 11, a mounting shell 12 fixedly installed on the first motor 11, and a mounting bracket 14 for supporting the mounting shell 12; when the first motor 11 is started, its output end will drive the first screw rod 13 to rotate. Since the first screw rod 13 is directly connected to the rotating shaft of the motor, the rotating speed of the screw rod is consistent with the rotating speed of the motor. At the same time, the mounting shell 12 and the mounting bracket 14 provide stable support and protection for the entire driving assembly 1, ensuring the stability and reliability of the screw rod during rotation;

[0037] Moreover, the driving assembly 1 can be widely applied to various mechanical equipment that requires rotational transmission, such as automation equipment, transmission devices, processing equipment, etc. By adjusting the parameters of the motor and the thread parameters of the screw rod, the transmission requirements in different application scenarios can be met.

[0038] The lifting assembly 2 consists of a driving cylinder 21, a driving head 22 fixedly installed at the output end of the driving cylinder 21, a connecting shell 23 fixedly installed on the driving head 22, and a driving block 24 fixedly installed on the connecting shell 23; when the driving cylinder 21 receives a control signal and starts, the internal air pressure or hydraulic pressure changes, pushing the piston rod to perform telescopic movement. This movement is transmitted to the connecting shell 23 and the driving block 24 through the driving head 22, causing them to perform lifting movements synchronously to adjust the position height of the welding, facilitating the extrusion contact welding of the copper bars.

[0039] The cooling assembly 3 consists of a mounting plate 31, a second motor 32 fixedly installed on the mounting plate 31, a first rotating roller 33 fixedly installed on the output shaft of the second motor 32, a connecting frame 34 fixedly installed at the bottom of the second motor 32, a rotator 35 for blowing air at the welding position, a welding frame 36 fixedly installed on the mounting plate 31, and a water bag 37 fixedly installed on the mounting plate 31; when the second motor 32 is started, its output shaft drives the first rotating roller 33 to rotate, and the connecting frame 34 strengthens the fixation of the second motor 32 to prevent the second motor 32 from vibrating and causing deviation of the welding position;

[0040] The rotator 35 includes a second rotating roller 351, a rotating blade 352 fixedly installed at the end of the second rotating roller 351, and a stopper 353 fixedly installed on the welding frame 36. A plurality of fixing blocks are further provided on the first rotating roller 33. The fixing blocks are pressed against the water bag 37, and the second rotating roller 351 and the first rotating roller 33 are driven by pulleys; the second rotating roller 351 and the first rotating roller 33 are driven by pulleys, which means that when the first rotating roller 33 rotates, it will drive the second rotating roller 351 to rotate through the pulleys. The rotating blade 352 is fixedly installed at the end of the second rotating roller 351 and rotates with the rotation of the second rotating roller 351, generating an air flow to blow and cool the welding position. The stopper 353 is fixedly installed on the welding frame 36 to limit the rotation range of the rotator 35 and ensure its stability and safety during operation;

[0041] As a supplement: The fixing blocks on the first rotating roller 33 will produce a squeezing effect on the water bag 37 during rotation. This squeezing effect is used to push the coolant in the water bag 37 to a specific cooling area, and the coolant in the water bag 37 is pushed by the pressure change generated by the squeezing to cool the welding position. When the water bag 37 sprays the coolant on the welding position of the copper busbar, a large amount of steam will be generated due to the contact between high temperature and low temperature. By rotating the rotating blade 352, the steam is dispersed to prevent harm to the staff and prevent the steam from spreading and making it impossible to observe the welding situation of the copper busbar;

[0042] The cooling component 3 can be widely applied to various welding processes that require rapid cooling, especially when welding temperature-sensitive materials or components. By adjusting parameters such as the rotation speed of the motor, the blowing angle of the rotator 35, the amount of coolant in the water bag 37, and the squeezing degree between the fixing block and the water bag 37, the cooling requirements in different application scenarios can be met.

[0043] The moving component 5 includes a mounting seat 51, a floating chuck 52 fixedly installed on the mounting seat 51, a threaded rod 53 rotatably installed on the mounting seat 51, and a gear 54 fixedly installed at the end of the threaded rod 53. A plurality of racks are provided on the driving block 24, and the racks are engaged with the gear 54; when the driving block 24 rises and falls, the gear 54 will rotate up or down with the driving block 24, and the thread on the threaded rod 53 will produce a linear motion. When the gear 54 rotates, it will drive the threaded rod 53 to rotate to drive the floating chuck 52 to move.

[0044] The floating chuck 52 includes a top plate 521 threadedly connected to the threaded rod 53, a first spring 522 fixedly installed at the bottom of the top plate 521, a clamping plate 523 fixedly installed at the bottom of the top plate 521, a floating head 524 slidably installed on the clamping plate 523, and a second spring 525 fixedly installed on the side of the floating head 524. A groove facilitating the movement of the floating head 524 is provided on the side of the clamping plate 523; the floating chuck 52 is based on the elastic force of the spring and the sliding adjustment function of the floating head 524. When an object needs to be clamped, first place the floating chuck 52 above the object, and then adjust the height of the top plate 521 and its components below by rotating the threaded rod 53. As the height of the top plate 521 decreases, the first spring 522 starts to compress, and the clamping plate 523 gradually approaches the object. When the clamping plate 523 contacts the object to be clamped, the floating head 524 will slide and adjust on the clamping plate 523 to adapt to the shape and size of the object. At the same time, the second spring 525 also plays a role in buffering and shock absorption to protect the object to be clamped from damage. By adjusting the height of the threaded rod 53 and the position of the floating head 524, precise clamping and fine adjustment of the object to be clamped can be achieved;

[0045] As a supplement: The groove provided on the side of the clamping plate 523 is the key for the floating head 524 to slide and adjust its position. The design of this groove enables the floating head 524 to move freely within a certain range, thereby achieving precise clamping and fine adjustment of the object to be clamped. When the shape or size of the object to be clamped changes, the floating head 524 can make corresponding adjustments within the groove to maintain close contact and stable clamping with the object to be clamped;

[0046] Moreover, when using the floating chuck 52, the stability and precision of components such as the threaded rod 53, the top plate 521, and the clamping plate 523 should be ensured to avoid affecting the clamping effect due to component loosening or insufficient precision. The contact surface between the floating head 524 and the clamping plate 523 should be kept clean and lubricated to reduce friction and wear and improve the flexibility and precision of sliding adjustment.

[0047] The limiting component 6 is composed of a fixed frame 61, a driven frame 62 fixedly installed on the fixed frame 61, a moving seat 63 fixedly installed on the driven frame 62, a guide rail 64 slidably installed on the moving seat 63, and a connecting pipe 65 fixedly installed on the moving seat 63; the limiting component 6 provides a stable foundation through the fixed frame 61, the driven frame 62 and the moving seat 63 cooperate to limit the movement range, the guide rail 64 slides on the moving seat 63 to achieve precise guidance, and the connecting pipe 65 may be used to connect or support other components, and they work together to achieve precise and stable limiting functions.

The special-shaped parts can be customized according to the description in the specification and the drawings.
