Description

Technical Field

[0001] This invention relates to the field of copper busbar extrusion production technology, specifically to an energy-saving, high-quality copper busbar extrusion equipment. Background Technology

[0002] The mainstream extrusion processes for copper busbars are divided into three categories: continuous extrusion, cold extrusion, and hot extrusion. Among them, continuous extrusion relies on friction to generate heat without external heating, is suitable for conventional copper busbars, and has a fast production speed; cold extrusion is formed under high pressure at room temperature, focuses on thin busbars, has excellent surface and high precision, and is only suitable for high-precision thin material production; while hot extrusion heats the copper ingot and forms it under high pressure, with strong forming ability and high strength, but high energy consumption and low efficiency.

[0003] In the existing hot extrusion process, the copper rod is first heated by a heating device. Once the copper rod is heated to a preset temperature, it is conveyed to the feed end of the extrusion device by a conveying device. At this time, the material support assembly of the extrusion device pushes the copper rod to the front of the feed port of the forming die. Then, the press is turned on, and its pressure head presses the copper rod into the forming die. Under pressure, the copper rod passes through the forming die and forms a preset shape. However, during this process, the temperature of the copper rod gradually decreases as it is conveyed from the heating device to the extrusion device. If the temperature is too low, it will affect the subsequent extrusion forming effect and may cause cracks or dimensional deviations in the profile. Therefore, heat treatment is required, which requires excessive heating to ensure that the temperature is sufficient during extrusion. This inevitably leads to a significant increase in energy consumption. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving, high-quality copper busbar extrusion device to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving, high-quality copper busbar extrusion device, comprising a feeding assembly, an extrusion mechanism, and a forming die. The feeding assembly includes a frame section, a material support structure, and a heating structure. Several material support structures are distributed on the frame section. When the frame section rotates, the material support structures rotate synchronously. Along their rotation path, an extrusion position, a feeding position, and a heating section are sequentially provided.

[0006] At the extrusion position, the extrusion mechanism presses the copper rod inside the material support structure into the forming mold;

[0007] At the feeding position, the material support structure automatically unfolds to receive the new copper rod;

[0008] The heating section uses a heating structure to heat the copper rod.

[0009] Preferably, the frame includes a housing, a fixed disk, and a rotating disk, with the fixed disk fixedly installed inside the housing and the rotating disk rotatably connected to the inner wall of the housing.

[0010] Preferably, it also includes a drive unit for driving the rotary disk to rotate.

[0011] Preferably, the rotating disk has a through hole, and the through hole is compatible with the copper rod.

[0012] Preferably, the material support structure includes an arc-shaped frame, a guide rail, a limit buckle, contact rollers, a driven member, a follower member, an elastic part, and an opening / closing part. A pair of contact rollers are rotatably connected to both ends of the arc-shaped frame, and the driven member is fixedly installed on one of the contact rollers. The limit buckle is slidably connected to the arc-shaped frame, and the follower member is rotatably connected to the limit buckle. The guide rail is installed on the arc-shaped frame and configured to restrict the limit buckle to move only on the arc-shaped frame. The elastic part applies a pushing force to the limit buckle so that the limit buckle tends to close the arc-shaped frame. During the process of the arc-shaped frame rotating from the extrusion position to the feeding position, the opening / closing part controls the opening and closing of the limit buckle.

[0013] Preferably, the elastic part includes a guide rod and a spring. The guide rod is fixedly installed inside the arc-shaped frame, and the spring is movably sleeved on the guide rod. The spring applies a pushing force to the limiting buckle.

[0014] Preferably, the opening and closing part includes a guide block. During the process of the arc frame rotating from the extrusion position to the feeding position, the end of the driven member first abuts against the upper part of the guide block. As the rotation continues, until the feeding position is reached, the driven member is attached to the bottom surface of the guide block.

[0015] Preferably, the heating structure includes flame nozzles, with a plurality of flame nozzles arranged along the inner wall of the frame portion.

[0016] Preferably, the housing has a connecting hole at the extrusion position. One end of the connecting hole is connected to the feed end of the forming mold, and the other end is connected to a through hole. When the central axis of the copper rod is aligned with the connecting hole, the copper rod will enter the mold through the connecting hole after being extruded by the extrusion mechanism.

[0017] Preferably, the passive component is a gear, and the fixed disk is provided with an annular rack. The gear meshes with the annular rack to realize the transmission connection between the passive component and the fixed disk.

[0018] In the above technical solution, the present invention provides an energy-saving high-quality copper busbar extrusion equipment that integrates the heating section into the rotation path of the material support structure. When the copper rod rotates synchronously with the material support structure, it achieves close-range and continuous heating, reduces heat loss, and avoids ineffective energy consumption and waste. In the rotation path, the continuous process of automatic opening and closing of feeding, heating of the heating section, and precise extrusion is completed in sequence. There is no need to set up an additional independent conveying device, which simplifies the connection of traditional heating and conveying processes, reduces process waiting time, and eliminates the need for manual intervention to receive the copper rod, further improving the degree of automation and solving the problem of low efficiency in traditional hot extrusion.

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-7This invention provides an energy-saving, high-quality copper busbar extrusion device, comprising a feeding assembly 1, an extrusion mechanism 2, and a forming die 3. The feeding assembly 1 includes a frame section, a material support structure 4, and a heating structure 7. Several material support structures 4 are distributed on the frame section. When the frame section rotates, the material support structures 4 rotate synchronously. Along their rotation path, there are sequentially arranged extrusion positions, feeding positions, and heating sections.

[0030] At the extrusion position, the extrusion mechanism 2 presses the copper rod 5 inside the material support structure 4 into the forming mold 3;

[0031] At the feeding position, the material support structure 4 automatically unfolds to receive the new copper rod 5;

[0032] The heating section, heating structure 7, heats the copper rod 5.

[0033] In an embodiment of the present invention, the equipment uses the frame as the core of rotation and a number of material support structures 4 are evenly distributed on the frame. The material support structures 4 can rotate synchronously with the frame to form a circulation path. On this rotation path, there are three key workstations: feeding position, heating section, and extrusion position, so that the material support structures 4 carry the copper rods 5 to complete the receiving of new materials, preheating treatment, and extrusion molding in sequence, thereby achieving energy saving and high-efficiency production.

[0034] In this embodiment, when the material support structure 4 rotates with the frame to the feeding position, its mechanical structure triggers an automatic unfolding action, forming a receiving space matching the copper rod 5. After the new copper rod 5 is placed in, the structure automatically closes. During the placement of the copper rod 5, the extrusion mechanism 2 extrudes the copper rod 5 in the extrusion position in real time. After the receiving is completed, the frame continues to rotate, sending the material support structure 4 and the copper rod 5 into the heating section. In this process, the feeding is automated, and there is no need for manual adjustment of the position of the copper rod 5. When entering the heating section, the material support structure 4 automatically closes to ensure the stability of the conveying. The heating structure 7 is fixedly arranged next to the rotation path of the material support structure 4, forming a heating section of a specific length. When the material support structure 4 carries the fixed copper rod 5 through the heating section, the heating structure 7 automatically closes to ensure the stability of the conveying. The heating structure 7 continuously heats the copper rod 5. At the same time, the copper rod 5 rotates slowly with the material support structure 4, so that all parts of the copper rod 5 can be evenly contacted by the heat source in all directions, avoiding local overheating or insufficient heating. This can achieve uniform preheating of the copper rod 5, improving its plasticity. Secondly, the heating process is parallel to the rotation of the material support structure 4 and the subsequent extrusion process of the extrusion mechanism 2. That is, when one copper rod 5 is being extruded, the other copper rods 5 are simultaneously preheated in the heating section to avoid heat loss during the transfer of the copper rods 5 after heating. Moreover, from the time of feeding, the copper rods 5 are in a relatively closed space before the extrusion is completed, with minimal heat loss and less oxidization. In this way, the quality of the extruded copper busbar is improved. This invention solves the problem of uneven heating and avoids heat loss, reducing energy consumption from the root.

[0035] In the final stage of this embodiment, when the material support structure 4 rotates to the extrusion position carrying the preheated copper rod 5, the thrust direction of the extrusion mechanism 2 and the feed port of the forming mold 3 are completely coaxial. Subsequently, the extrusion mechanism 2 starts and applies a stable thrust along the axis of the copper rod 5, forcibly pressing the copper rod 5 into the cavity of the forming mold 3. Under high temperature and high pressure, the copper rod 5 undergoes plastic deformation, completely filling the cavity of the forming mold 3, and finally being extruded from the discharge port of the forming mold 3 to form a copper busbar product with the same shape as the cavity of the forming mold 3. After extrusion, the extrusion mechanism 2 withdraws, while the material support structure 4 continues to rotate with the frame part and enters the next round of feeding cycle. In this stage, through the precise positioning of the support structure, the coaxiality of the extrusion mechanism 2 and the forming mold 3 is accurate, and the precise extrusion ensures high dimensional accuracy of the copper busbar, good surface finish, and no problems such as cross-sectional skewing or burrs caused by off-center loading. Moreover, the extrusion is continuously connected with the feeding process of the subsequent feeding component 1 and the heating process of the heating structure 7, without any gaps in operation, which greatly improves efficiency.

[0036] In another embodiment of the present invention, please refer to Figure 4 The frame includes a housing 11, a fixed disk 12, and a rotating disk 13. The fixed disk 12 is fixedly installed inside the housing 11, and the rotating disk 13 is rotatably connected to the inner wall of the housing 11.

[0037] It also includes a drive unit 8, which is used to drive the rotating disk 13 to rotate.

[0038] The rotating disk 13 is rotatably connected to the inner wall of the housing 11. Its rotating surface is parallel to the fixed disk 12 and the gap is uniform. Several material support structures 4 are evenly distributed along the circumference of the rotating disk 13 to ensure the stability of the material support structures 4 when rotating synchronously with the rotating disk 13. The housing 11 serves as an external protection and overall load-bearing structure, which plays the role of isolating internal and external heat exchange.

[0039] The drive unit 8 can be connected to the rotating disk 13 via a servo motor and gears. Its core function is to provide power for the rotation of the rotating disk 13. During operation, the drive unit 8 starts according to the preset speed and direction, and transmits power to the rotating disk 13, causing the rotating disk 13 to rotate at a constant speed around its own central axis. Since the material support structure 4 is fixed on the rotating disk 13, the material support structure 4 rotates synchronously with the rotating disk 13, thereby driving the copper rod 5 to pass through the feeding position, heating section and extrusion position in sequence, realizing the cyclic connection of each process.

[0040] In another embodiment of the present invention, the rotating disk 13 is provided with a through hole 131, and the through hole 131 is adapted to the copper rod 5.

[0041] The through hole 131 is not only used for the passage of the copper rod 5, but also allows the copper rod 5 to move towards the through hole 131 as it rotates after feeding. This allows for dual fixation by positioning through the through hole 131 and clamping by the material support structure 4, which greatly improves the rotational stability of the rotating disk 13 and the positioning accuracy of the copper rod 5.

[0042] In another embodiment of the present invention, please refer to Figure 5-6 The material support structure 4 includes an arc-shaped frame 41, a guide rail 411, a limiting buckle 42, a contact roller 43, a passive member 44, a driven member 45, an elastic part, and an opening and closing part. A pair of contact rollers 43 are rotatably connected to both ends of the arc-shaped frame 41, and the passive member 44 is fixedly installed on one of the contact rollers 43. The limiting buckle 42 is slidably connected to the arc-shaped frame 41, and the driven member 45 is rotatably connected to the limiting buckle 42. The guide rail 411 is installed on the arc-shaped frame 41 and is configured to restrict the limiting buckle 42 to move only on the arc-shaped frame 41. The elastic part applies a pushing force to the limiting buckle 42 so that the limiting buckle 42 tends to close the arc-shaped frame 41. During the process of the arc-shaped frame 41 rotating from the extrusion position to the feeding position, the opening and closing part controls the opening and closing of the limiting buckle 42.

[0043] The passive component 44 is a gear, and the fixed disk 12 is provided with an annular rack. The gear meshes with the annular rack to realize the transmission connection between the passive component 44 and the fixed disk 12.

[0044] As the rotating disk 13 rotates from the extrusion position to the feeding position, the opening and closing part begins to contact the driven member 45 of the material support structure 4, triggering the power transmission of the opening and closing action. As the rotating disk 13 continues to rotate, the opening and closing part applies a force to the driven member 45. Since the driven member 45 is rotatably connected to the limiting buckle 42, and the limiting buckle 42 is restricted by the guide rail 411 on the arc frame 41 and can only move along the arc frame 41, the driven member 45 drives the limiting buckle 42 to slide along the guide rail 411 under the force. At this time, the elastic part is compressed, and the limiting buckle 42 overcomes the thrust of the elastic part and moves away from the closed end of the arc frame 41, that is, it retracts, so that the material support structure 4 forms an open receiving space that is compatible with the copper rod 5.

[0045] When the material support structure 4 arrives precisely at the feeding position along with the rotating disk 13, a hopper 6 is provided at the machine casing 11, the limit buckle 42 remains open, the new copper rod is put in along the hopper 6, and the bottom of the copper rod 5 contacts the two contact rollers 43.

[0046] After the material support structure 4 receives the copper rod 5, it continues to rotate with the rotating disk 13 and disengages from the range of action of the opening and closing part. The force exerted by the opening and closing part on the driven member 45 disappears, and the elastic part releases the thrust to push the limit buckle 42 to slide in the opposite direction along the guide rail 411 until the limit buckle 42 cooperates with the arc frame 41 to form a clamping space, firmly clamping the copper rod 5. During the continuous rotation, the copper rod 5 is driven to rotate synchronously by the rotation drive of the contact roller 43. Since the driven member 44 is connected to the fixed disk 12, the two mesh and drive each other by means of a ring rack on the fixed disk 12 and the driven member 44 is a matching gear. When the material support structure 4 rotates around the fixed disk 12 with the rotating disk 13, it can perform a large-scale transfer. When in motion, the passive component 44 rotates under the transmission action of the fixed disk 12, which in turn drives the contact roller 43 fixedly connected to it to rotate synchronously. Since the contact roller 43 is in close contact with the copper rod 5, the friction force drives the copper rod 5 to rotate synchronously, so that the copper rod 5 can complete its rotation while revolving around the fixed disk 12. In this way, the rotating copper rod 5 is fed into the heating section through the material support structure 4, so that the copper rod 5 can be heated evenly in all directions in the heating section, and the all-round heating of the copper rod 5 is completed with low energy consumption. Through the follow-up uniform heating and parallel extrusion and feeding actions of the heating structure 7 in this process, the problem of uneven heating is solved and heat loss is avoided, thus reducing energy consumption from the source.

[0047] In an embodiment of the present invention, the elastic part includes a guide rod 412 and a spring 413. The guide rod 412 is fixedly installed inside the arc-shaped frame 41, and the spring 413 is movably sleeved on the guide rod 412. The spring 413 applies a pushing force to the limiting buckle 42.

[0048] The opening and closing part includes a guide block 47. During the process of the arc frame 41 rotating from the extrusion position to the feeding position, the end of the follower 45 first abuts against the upper part of the guide block 47. As the rotation continues, until the feeding position is reached, the follower 45 is attached to the bottom surface of the guide block 47.

[0049] Under normal conditions, the spring 413 applies a continuous pushing force to the limit buckle 42, causing the limit buckle 42 to tend to close the arc frame 41. The core component of the opening and closing part is the guide block 47, which is fixed on the circumferential wall of the equipment housing 11. It cooperates with the driven member 45 to realize the active retraction of the limit buckle 42. During the process of the arc frame 41 rotating from the extrusion position to the feeding position, the end of the driven member 45 first abuts against the upper part of the guide block 47. As the rotating disk 13 continues to drive the arc frame 41 to rotate, the driven member 45 gradually slides along the upper part of the guide block 47 to the bottom surface until the material support structure 4 reaches the feeding position. At this time, the driven member 45 is completely attached to the bottom surface of the guide block 47. During this process, the retraction action of the limit buckle 42 is completed. After moving to the heating section, the driven member 45 and the guide block 47 separate. Under the action of the elastic force of the elastic part, the limit buckle 42 is formed and closed, so as to realize that the contact roller 43 and the driven member 45 completely restrict the copper rod 5.

[0050] In an embodiment of the present invention, the heating structure 7 includes a flame nozzle, and a plurality of flame nozzles are arranged along the inner wall of the frame portion.

[0051] The nozzle is oriented towards the center of the orbital trajectory of the copper rod 5, forming a full-circumference heating area, which heats the copper rod 5 evenly as it passes by.

[0052] In an embodiment of the present invention, the housing 11 has a connecting hole 111 at the extrusion position. One end of the connecting hole 111 is connected to the feed end of the forming mold 3, and the other end is connected to the through hole 131. When the central axis of the copper rod 5 is aligned with the connecting hole 111, the copper rod 5, after being extruded by the extrusion mechanism 2, will enter the mold through the connecting hole 111. The copper rod 5 enters the cavity of the forming mold 3 through the connecting hole 111. The housing 11, the connecting hole 111, the through hole 131, and the forming mold 3 are precisely aligned. With the coaxial positioning design, the coaxiality of the copper rod 5 extruded into the mold is further improved.

[0053] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
