Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic transformers, and in particular to a copper wire winding and extrusion device for photovoltaic transformers. Background Art

[0002] Flat copper wire has become a key technical material in photovoltaic transformers due to its high conductivity, heat dissipation advantages, and compact design. It is particularly suitable for inverters, isolation transformers, and high-frequency magnetic components. The production process for flat copper wire requires continuous extrusion to extrude oxygen-free copper rods into flat copper wire.

[0003] In the existing patent announcement number CN108231401B, a copper wire winding and extrusion device for photovoltaic transformers is disclosed, including an operating table, grooves are provided at the four corners of the lower end of the operating table, a buffer mechanism is provided in the groove, the lower end of the buffer mechanism is fixedly connected to a support column, the upper end of the operating table is fixedly connected to a first support rod and a second support rod, a wire pay-off disk is fixedly connected to the side wall of the first support rod, a wire pay-off groove is provided on the side wall of the wire pay-off disk, a copper wire body is wound in the wire pay-off groove, a first drive device is fixedly connected to the side wall of the second support rod, the output shaft end of the first drive device passes through the second support rod and is fixedly connected to an extrusion disk, and an annular groove is provided on the side wall of the extrusion disk.

[0004] In the above technical solution, the material is discharged through the pay-off reel, the copper wire is extruded into shape through the extrusion reel, and finally wound up by the take-up reel to complete the extrusion work. However, the single extrusion of the copper wire by the extrusion reel usually requires extremely high extrusion force and large-tonnage equipment, and is prone to cracking or dimensional deviation due to local stress concentration. The finished copper wire is also prone to surface wrinkles or internal microcracks. Moreover, usually in the actual production line, the company will also be equipped with a straightening system and a cleaning device to process the copper rod raw material before entering the extruder. The temperature of the formed flat copper wire is relatively high at this time, and a cooling system needs to be set at the outlet. It then goes through processes such as drying and metering before finally completing the winding. This means that manufacturers of flat copper wire often need to use production plants with a large area, which greatly increases the site cost, but only completes the extrusion of the copper wire, resulting in low site utilization.

[0005] Therefore, it is necessary to provide a copper wire winding and extrusion device for photovoltaic transformers, which can achieve progressive multiple extrusions and greatly reduce the footprint of the equipment. Summary of the Invention

In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0042] See also Figure 1-7 The present invention provides a technical solution: a copper wire winding and extrusion device for photovoltaic transformers, comprising a continuous extruder 1 and an oxygen-free copper rod 6.

[0043] The continuous extruder 1 includes a driving die base 101 and a plurality of driven die bases 102. The driven die bases 102 are distributed in a ring with the driving die base 101 as the axis. An annular pressure groove 103 is provided on the middle side of the driving die base 101. An extrusion ring 104 is provided on the outer side of the driven die base 102. The extrusion ring 104 is adapted to the annular pressure groove 103. The diameters of the extrusion rings 104 of the driven die bases 102 increase in a step-like manner.

[0044] The oxygen-free copper rod 6 enters the annular pressing groove 103 and is continuously extruded by a plurality of extrusion rings 104 of the movable die base 102 to form the flat copper wire body 5;

[0045] A feed port and a discharge port are provided on the same side of the continuous extruder 1 . The oxygen-free copper rod 6 enters the continuous extruder 1 from the feed port and surrounds the active die base 101 and extends out from the discharge port.

[0046] By setting an active die base 101 and a plurality of driven die bases 102, and the plurality of driven die bases 102 surround one side of the active die base 101, the oxygen-free copper rod 6 enters the continuous extruder 1 through the feed port, and the oxygen-free copper rod 6 first enters the annular pressing groove 103. As the active die base 101 rotates, the oxygen-free copper rod 6 first contacts the first driven die base 102. The driven die base 102 rotates under the drive of the active die base 101, so that the oxygen-free copper rod 6 enters between the two, and the extrusion ring 104 performs the initial extrusion deformation on it. As the first driven die base 102 and the active die base 101 squeeze and clamp the oxygen-free copper rod 6, the oxygen-free copper rod 6 fits into the annular pressing groove 103 of the active die base 101 and enters the second driven die base 102 for extrusion molding. And so on, the oxygen-free copper The rod 6 is continuously extruded by several driven die bases 102 in turn. At the same time, the oxygen-free copper rod 6 is circled around the active die base 101 to complete the extrusion molding to form the flat copper wire body 5, which extends out from the discharge port. That is to say, while the oxygen-free copper rod 6 is being progressively extruded, its feeding and discharging are both carried out on the same side, saving the site space on the other side of the continuous extruder 1, so that the floor space required for the traditional extrusion assembly line is reduced by half. The work site that was originally only able to carry out the feeding processing process can now realize the simultaneous feeding and discharging, thereby improving the site utilization rate and saving costs. In addition, the diameters of several extrusion rings 104 are gradually increased, so that the flat copper wire body 5 is deformed step by step and the shape can be gradually adjusted, further improving the forming size and shape accuracy, and the step-by-step extrusion reduces the single deformation stress, and the surface quality is good.

[0047] The continuous extruder 1 also includes an extrusion chamber, which includes a pair of supporting side plates 201, a C-shaped arc plate 202 fixedly connected between the pair of supporting side plates 201, the axis of the C-shaped arc plate 202 coincides with the axis of the active die base 101, and a plurality of inner arc cover plates 2 are arranged on the inner side of the C-shaped arc plate 202. The plurality of inner arc cover plates 2 are respectively arranged between two adjacent driven die bases 102, and the inner curvature of the inner arc cover plate 2 is adapted to the active die base 101.

[0048] Preferably, unlike the traditional extruded straight oxygen-free copper rod 6, the present application starts with the extrusion process. When the oxygen-free copper rod 6 is first loaded, it needs to pass through multiple driven die seats 102 in sequence and finally go around the active die seat 101 for a circle before being discharged, which greatly increases the difficulty of the initial loading. Therefore, a plurality of inner arc cover plates 2 are provided. The inner arc cover plates 2 are provided between two adjacent driven die seats 102, and the inner curvature of the inner arc cover plates 2 is adapted to the active die seat 101, so that the inner arc cover plates 2 can fit the active die seat 101. On the outside of the active die base 101, when the oxygen-free copper rod 6 is initially loaded, its head end passes through the first driven die base 102 and is restricted by the inner arc cover plate 2 in the annular pressing groove 103. As the first driven die base 102 and the active die base 101 are extruded and transmitted, the head end of the oxygen-free copper rod 6 is transferred along the annular pressing groove 103 to the next driven die base 102, and so on, until it is extended from the discharge port after multiple extrusions are completed, thereby completing the initial loading work and improving the convenience of loading.

[0049] A pair of L-shaped baffles 203 are provided on the open side of the C-shaped arc plate 202, and the pair of L-shaped baffles 203 extend to the feed port and the discharge port. The feed port and the discharge port are both provided with a pair of adaptation wheels 204, and an adaptation groove is provided in a ring shape on the middle side of the adaptation wheel 204. A transition wheel is provided on the lower side of the L-shaped baffle 203 adjacent to the feed port, and a triangular guide block 205 is fixedly connected to the upper end of the L-shaped baffle 203 adjacent to the discharge port, and a guide slope is provided at the right-angle center of the L-shaped baffle 203, and the guide slope is connected to the triangular guide block 205.

[0050] Preferably, in order to facilitate the transition of the oxygen-free copper rod 6 from the first feeding into the feed port to the outgoing discharge port, an L-shaped baffle 203 is provided. Specifically, the oxygen-free copper rod 6 enters the feed port through the adaptation wheel 204, and the upper end of the annular pressing groove 103 is kept at the same horizontal line as the adaptation wheel 204, so that the oxygen-free copper rod 6 passes through the transition wheel and enters the annular pressing groove 103 of the active die base 101. Since the diameter of the extrusion ring 104 of the first driven die base 102 is the smallest, the inner arc cover plate 2 does not need to be provided, and the oxygen-free copper rod 6 can complete the extrusion and the feeding transition.

[0051] Preferably, when the head end of the oxygen-free copper rod 6 completes the extrusion molding of the last slave die base 102, a guide slope and a triangular guide block 205 are provided to facilitate its guidance to the discharge port. Specifically, when the head end of the oxygen-free copper rod 6 is transmitted to the discharge port, it naturally droops under the action of gravity, thereby contacting the guide slope and moving along the guide slope to the triangular guide block 205, thereby entering the adaptation wheel 204 of the discharge port to complete the discharge transition.

[0052] A pay-off mechanism 8 and a take-up mechanism 7 are provided on the same side of the continuous extruder 1 and are arranged adjacent to each other. The pay-off mechanism 8 includes a rotatable wheel frame 801, and the take-up mechanism 7 includes a rotatable take-up drum.

[0053] The pay-off mechanism 8 releases the oxygen-free copper rod 6 and enters the feed port through the guide mechanism;

[0054] The formed rectangular copper wire body 5 passes through a cooling assembly, an air drying assembly and a shifting rod assembly, and is then wound up by a wire taking-up mechanism 7 .

[0055] Preferably, since the feed port and the discharge port are on the same side, the wire-releasing mechanism 8 and the wire-reeling mechanism 7 can also be arranged adjacent to each other, so that the staff can load and unload the oxygen-free copper rod 6 material tray and the flat copper wire body 5 wound finished product on the same side, and the guide mechanism is stacked on the upper side of the cooling assembly, the air-drying assembly and the lever assembly, further saving floor space.

[0056] The cooling component includes a cooling pool 4, which is arranged at one end of the discharge port. Three sets of tensioning wheels 401 are arranged in the cooling pool 4, and the three sets of tensioning wheels 401 are arranged in a V shape. The flat copper wire body 5 is tensioned by the tensioning wheel 401 and immersed in the cooling pool 4 for cooling. The air-drying component air-dries the flat copper wire body 5. The air-drying component is a commonly used existing technology in this field, so it will not be described in detail here.

[0057] The lever assembly includes a translation frame 402 , a sliding frame 404 is slidably fitted on the upper side of the translation frame 402 , a pair of levers 403 is provided between the sliding frames 404 , and the flat copper wire body 5 passes through the pair of levers 403 .

[0058] Preferably, in order to facilitate the winding drum to evenly wind up the flat copper wire body 5, a pair of shift rods 403 are provided, which move horizontally on the translation frame 402 through the sliding frame 404, so that the pair of shift rods 403 drive the passing flat copper wire body 5 to deflect, so as to be evenly wound on the winding drum. The horizontal displacement of the sliding frame 404 can be driven by a linear drive component, and the linear drive component includes but is not limited to a lead screw mechanism or a gear rack mechanism, etc., which are all existing technologies in this field, so they will not be elaborated here.

[0059] The guide mechanism includes a bunching tube 405 , one end of which is provided with a jacking frame 406 , and the upper side of the jacking frame 406 is provided with a plurality of horizontal guide wheels 407 and vertical guide wheels 408 .

[0060] Preferably, by providing a bunching cylinder 405 and a plurality of horizontal guide wheels 407 and vertical guide wheels 408, the oxygen-free copper rods 6 released from the wheel rack 801 are centrally guided to facilitate their entry into the feed port.

[0061] One end of the inner arc cover plate 2 is fixedly connected to a pair of guide rods 206, and one end of the guide rod 206 is slidably matched with a guide sleeve 207. The guide sleeve 207 is fixed to the inner side of the C-shaped arc plate 202. Several inner arc cover plates 2 are driven to move by a linear drive mechanism.

[0062] Preferably, a linear drive mechanism is provided, such as a cylinder, etc. to drive the inner arc cover plate 2, and the guide sleeve 207 and the guide rod 206 are guided, so that when the oxygen-free copper rod 6 is loaded for the first time, when its head end passes through the first driven die seat 102, in order to prevent the head end from tilting up and escaping from the annular pressure groove 103, the linear drive mechanism drives the current inner arc cover plate 2 to be pressed down, thereby pressing the tilted head end into the annular pressure groove 103, restricting it from moving into the next driven die seat 102 for extrusion, and then the inner arc cover plate 2 can be reset away from the active die seat 101, and then restricted by the next inner arc cover plate 2, and so on, until the oxygen-free copper rod 6 completes the initial loading, and by setting the inner arc cover plate 2 to be movable, wear caused by continuous contact with the active die seat 101 is avoided.

[0063] The linear drive mechanism includes a roller rod 3. One end of the supporting side plate 201 is fixedly connected to an extended arc plate. The extended arc plate has a C-shaped groove 302 extending through it. Both ends of the roller rod 3 extend into the C-shaped groove 302. A pair of gears 301 are fixedly connected to both sides of the roller rod 3. Both ends of the C-shaped arc plate 202 are provided with sector teeth 303. The gears 301 mesh with the sector teeth 303. A rubber roller 304 is provided on the middle side of the roller rod 3.

[0064] A push rod 305 is fixedly connected to the middle side of the inner arc cover plate 2. The push rod 305 passes through the C-shaped arc plate 202 and slides with it. The outer end of the push rod 305 is fixedly connected to a T-shaped wheel frame 306. Rubber wheels 308 are provided on both sides of the T-shaped wheel frame 306. A tension spring is sleeved on the outer side of the push rod 305. The two ends of the tension spring are respectively connected to the C-shaped arc plate 202 and the inner arc cover plate 2.

[0065] When the roller 3 rotates, it drives a pair of gears 301 to rotate, and the gears 301 mesh and roll along the fan-shaped teeth 303, so that the roller 3 drives the rubber roller 304 to move along the C-shaped groove 302 to the position of the first driven die seat 102. The rubber roller 304 contacts the rubber wheel 308, thereby driving the push rod 305 and the inner arc cover plate 2 to press down along its wheel surface, thereby pressing the head end of the oxygen-free copper rod 6 down into the annular pressure groove 103. After completing the current extrusion work, the roller 3 can be moved to the second driven die seat 102 to limit the next position, and a tension spring is provided, and the push rod 305 can be automatically reset, so that the inner arc cover plate 2 that has completed the restriction is away from the active die seat 101, thereby realizing the sequential driving of the inner arc cover plate 2 for restriction. Compared with the use of three cylinders and supporting solenoid valves, air pipelines, air pumps, etc. for separate driving, the total cost is reduced.

[0066] A sprocket 1 309 is fixed to one end of the roller 3, and a sprocket 2 310 is provided on one side of the supporting side plate 201. The axis of the sprocket 2 310 coincides with the axis of the C-shaped groove 302. The sprocket 2 310 is driven to rotate by the motor assembly, and the sprocket 1 309 and the sprocket 2 310 are connected by a transmission chain.

[0067] Preferably, the motor assembly drives sprocket 2 310 to rotate, and the chain transmission drives sprocket 1 309 to rotate, thereby driving the roller 3 to rotate. Sprocket 2 310 is set at the axial position of the C-shaped groove 302, so that the motor assembly itself can output stably and drive sprocket 1 309 to move along the C-shaped groove 302.
