Description

Technical Field

[0001] The invention relates to the technical field of copper strip processing, and in particular to a copper strip extrusion device and an extrusion method. Background Art

[0002] The copper strip extrusion device is a device used to process copper strips. It applies huge pressure to make the copper material plastically deform in a specific mold, so as to obtain the copper strip of the desired shape and size. It is usually composed of the extruder body, hydraulic system, heating system and control system. During the extrusion process, the copper material is first placed in the extrusion barrel, and then pressure is applied through the hydraulic system to make the extrusion rod push the copper material through the die. During the extrusion process, the heating system will keep the temperature of the copper material within a suitable range to ensure its plastic deformation ability.

[0003] However, due to the different sizes and shapes of copper materials, the heating time required during the extrusion process will also be different. For larger copper materials, it often takes a long time to achieve thermoplastic deformation, and it may even happen that the outer layer has melted while the inner part has not yet been thermally softened. At this time, if the hydraulic system applies pressure, not only will it not be able to achieve plastic deformation of the copper material well, but it will also have an adverse effect on the service life of the mold and the hydraulic system, and thus seriously affect the plastic efficiency and plastic quality of the copper material.

[0004] Therefore, it is necessary to provide a copper strip extrusion device and an extrusion method to solve the above problems. Summary of the invention

The mounting seat is fixedly connected to the outer wall of the cooling and shaping bin, and the interior of the mounting seat is fixedly connected to a mounting shaft. The compacting plate is rotatably connected to the outer side of the mounting shaft through a connecting block, and a torsion spring is symmetrically fixedly connected between the connecting block and the mounting shaft.

[0016] As a further improvement of the above solution, a mounting sleeve is fixedly connected to the outer side of the mounting seat, a positioning block is slidably connected to the inside of the mounting seat, and a second spring is fixedly connected between the positioning block and the mounting sleeve.

In the thermoplastic forming bin, the copper material will be further heated to soften it further after deformation, so that the copper material can be softened more fully, and its plasticity can be enhanced, so that the thermoplastic forming effect is better and the product quality is higher. After that, the copper material enters the space separated by the guide plate and the shaping plate in the cooling shaping bin, and is compacted under the action of the compaction mechanism to eliminate the gap in the copper material, improve the density and strength of the product, avoid quality problems, and make the product more durable.

[0030] When the formed copper strip enters the interior of the heating coil, it will first push the movable rod downward, and then press the delay switch. The delay switch will control the heating coil to be energized for a period of time, and at the same time, the servo motor 2 will be powered off for a period of time.

The power failure of servo motor 2 makes the subsequent copper strip only push the previous copper strip to move, ensuring the welding quality while avoiding loose welding or defects caused by improper movement of the copper strip during the welding process, ensuring the stable quality of the welding point. When the heating coil is powered on and servo motor 2 is powered on, the copper strip can be unloaded stably. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figures 1 to 9 As shown, the present invention provides an embodiment: a copper strip extrusion device, including a device base 1, characterized in that it also includes:

[0044] The cutting assembly 2 includes a material loading bin 21 fixedly connected to the top of the device base 1, and a cutting knife 23 is evenly and fixedly connected inside the material loading bin 21;

[0045] The auxiliary component 3 is located on the top of the dividing component 2, and assists the dividing component 2 to achieve stable and efficient material loading;

[0046] The thermoplastic component 4 includes a thermoplastic extrusion bin 41, a thermoplastic forming bin 43 and a cooling and shaping bin 44. The thermoplastic extrusion bin 41 is fixedly connected to the feeding bin 21. The ends of the thermoplastic extrusion bin 41 and the cooling and shaping bin 44 that are close to each other are fixedly installed inside the thermoplastic forming bin 43. The inside of the thermoplastic extrusion bin 41 is evenly and fixedly connected with a partition 42. The inner wall of the cooling and shaping bin 44 is symmetrically and fixedly connected with a guide plate 45. The inside of the cooling and shaping bin 44 is evenly and fixedly connected with a shaping plate 47. The guide plate 45 and the shaping plate 47 both penetrate the thermoplastic forming bin 43 and are butt-jointed with the partition 42.

[0047] The welding assembly 5 includes a coil base 51 fixedly connected to the device base 1, a fixing seat 52 fixedly connected to the upper surface of the coil base 51, a heating coil 53 evenly fixedly connected to the top of the coil base 51, a delay switch 55 evenly fixedly installed inside the fixing seat 52, a movable rod 54 slidably connected to the top of the fixing seat 52, and the movable rod 54 is fixedly connected to the pressing end of the delay switch 55;

[0048] The blanking assembly 6 is located on the top of the device base 1 and is used to support and blank the shaped copper strip.

[0049] In practical application, the embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, first, the copper strip is placed on the auxiliary component 3, and the auxiliary component 3 stably transports the copper strip to the upper bin 21 of the segmentation component 2. After entering the upper bin 21, the copper strip is segmented by the segmentation knives 23 evenly distributed inside, so that the size of the copper strip is more uniform;

[0050] like Figure 2 and Figure 3 As shown, the split copper strip enters the thermoplastic extrusion chamber 41 of the thermoplastic component 4, and the thermoplastic extrusion chamber 41 heats the copper strip to soften its outer side, thereby reducing the deformation difficulty of the copper strip in the subsequent movement process, so that the copper strip is easier to be processed into a desired shape, greatly improving the efficiency and quality of thermoplastic processing. The partition 42 in the thermoplastic extrusion chamber 41 plays a role in guiding the moving direction of the copper strip, ensuring that the copper strip can accurately enter the thermoplastic forming chamber 43;

[0051] In the thermoplastic forming chamber 43, the copper strip is further heated, and the deformed copper strip is further softened, which fully enhances its plasticity, making the thermoplastic forming effect better and the product quality higher. Then, the copper strip enters the cooling and shaping chamber 44 through the guide plate 45 and the shaping plate 47 that are butt-jointed with the partition plate 42. The guide plate 45 and the shaping plate 47 not only ensure that the copper strip accurately enters the cooling and shaping chamber 44, avoiding deviation or misalignment, and improving the processing accuracy and reliability, but also separates a specific space in the cooling and shaping chamber 44, and the copper strip is compacted in the space under the action of the compacting mechanism 46, eliminating the gap in the copper strip, improving the density and strength of the product, avoiding quality problems, and making the product more durable.

[0052] like Figure 1 and Fig. 9 As shown, when the formed copper strip enters the welding assembly 5, it will first push the movable rod 54 to move downward, and then press the delay switch 55. The delay switch 55 controls the heating coil 53 to be energized and lasts for a period of time. At the same time, the unloading assembly 6 is powered off for a period of time. The heating coil 53 is energized to heat the cross-sectional part of the copper strip. If there is subsequent copper strip feeding, the welding between the two sections of copper strip can be achieved. The power-off of the unloading assembly 6 makes the subsequent copper strip only push the previous copper strip to move, ensuring the welding quality, avoiding loose welding or defects due to improper movement of the copper strip during the welding process, and ensuring the stable quality of the welding point. When the heating coil 53 is powered on and the unloading assembly 6 is powered on, the processed copper strip is smoothly taken out of the device to prepare for the next processing.

[0053] like Figure 2 and Figure 5 As shown, the dividing assembly 2 also includes a feeding roller 22 which is evenly rotatably connected to the inside of the feeding bin 21, the inside of the device base 1 is rotatably connected to a driving shaft 26, one end of the feeding roller 22 located in the device base 1 is fixedly connected to a worm gear 24, the outside of the driving shaft 26 is evenly fixedly connected to a worm 25, the worm 25 is meshed with the worm gear 24, a servo motor 27 is fixedly mounted on the outer wall of the device base 1, and the output end of the servo motor 27 is fixedly connected to the driving shaft 26 through a coupling.

[0054] In actual application of the embodiment of the present invention, the servo motor 27 is started, and the output end of the servo motor 27 drives the driving shaft 26 to rotate. The worm 25 evenly distributed on the outside of the driving shaft 26 rotates synchronously with the driving shaft 26. Since the worm 25 is meshed with the worm wheel 24, the rotation of the worm 25 drives the worm wheel 24 to rotate. The worm wheel 24 is fixedly connected to one end of the feeding roller 22 located in the device base 1, so that the feeding roller 22 rotates evenly under the drive of the worm wheel 24. The rotation of the feeding roller 22 can help the copper strip to smoothly enter the feeding bin 21, and make After entering the loading bin 21, the copper strip can be transported forward more smoothly to avoid jamming or accumulation. At the same time, the rotation speed of the loading roller 22 can be adjusted by a servo motor 27 to meet the loading requirements of copper strips of different sizes and thicknesses, thereby improving the versatility and adaptability of the device. After entering the loading bin 21 with the assistance of the loading roller 22, the copper strip is cut by the evenly distributed cutting knives 23 inside, making the size of the copper strip more uniform. Then, the cut copper strip enters the thermoplastic component 4, the welding component 5, and is unloaded through the unloading component 6.

[0055] like Figure 2 and Figure 4 As shown, the auxiliary component 3 includes a support seat 31 fixedly connected to the top of the loading bin 21, a hydraulic cylinder 35 is symmetrically fixedly installed on the top of the support seat 31, a movable seat 32 is slidably connected to the inside of the loading bin 21, a pressure roller 33 is evenly fixedly connected to the bottom of the movable seat 32, a connecting sleeve 34 is symmetrically fixedly connected to the top of the movable seat 32, the telescopic ends of the hydraulic cylinder 35 all pass through the support seat 31 and are slidably connected to the inside of the connecting sleeve 34, a pressure sensor 36 is slidably connected to the inner side of the connecting sleeve 34, the pressure sensor 36 is fixedly connected to the telescopic end of the hydraulic cylinder 35, and a spring 37 is fixedly connected between the detection end of the pressure sensor 36 and the movable seat 32.

[0056] In actual application of the embodiment of the present invention, the hydraulic cylinder 35 is started, and the telescopic end of the hydraulic cylinder 35 extends downward, pushing the connecting sleeve 34, the movable seat 32 and the pressure roller 33 to move downward, and the pressure roller 33 gradually approaches the copper strip in the loading bin 21, exerting a certain pressure on the copper strip to ensure that the copper strip can stably enter the loading bin 21 and maintain good position accuracy in the subsequent processing. In the process of the pressure roller 33 exerting pressure on the copper strip, the pressure sensor 36 can detect the pressure of the pressure roller 33 on the copper strip in real time. When the pressure reaches the preset value, the hydraulic cylinder 35 stops extending and maintains the current state. If the pressure is too large or too small, the hydraulic cylinder 35 can Corresponding adjustments are made according to the feedback signal of the pressure sensor 36 to ensure that the copper strip is subjected to appropriate pressure. The spring 37 on the inner side of the connecting sleeve 34 plays a buffering role. When the copper strip has thickness changes or other unstable factors during processing, the spring 37 can absorb part of the impact force to prevent the pressure sensor 36 and the hydraulic cylinder 35 from being subjected to excessive instantaneous pressure, thereby protecting the safe operation of the equipment. Through the action of the auxiliary component 3, the copper strip can enter the cutting component 2 for cutting more stably and efficiently, providing good prerequisites for subsequent thermoplastic, welding and other processing processes, thereby improving the processing accuracy and production efficiency of the entire device.

[0057] like Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, a plurality of compacting mechanisms 46 are symmetrically arranged on the outer side of the cooling and shaping bin 44, and the compacting mechanism 46 includes a compacting plate 461 and a mounting seat 462. The mounting seat 462 is fixedly connected to the outer wall of the cooling and shaping bin 44, and the interior of the mounting seat 462 is fixedly connected with a mounting shaft 466. The compacting plate 461 is rotatably connected to the outer side of the mounting shaft 466 through a connecting block 465, and a torsion spring 468 is symmetrically fixedly connected between the connecting block 465 and the mounting shaft 466. A mounting sleeve 463 is fixedly connected to the outer side of the mounting seat 462, and a positioning block 464 is slidably connected to the interior of the mounting seat 462, and a spring 2 467 is fixedly connected between the positioning block 464 and the mounting sleeve 463.

[0058] In actual application of the embodiment of the present invention, after the copper strip enters the cooling and shaping bin 44, the compacting mechanism 46 starts to play a role. Under the action of the torsion spring 468, the compacting plate 461 is initially located close to the inner wall of the cooling and shaping bin 44. As the copper strip moves in the cooling and shaping bin 44, the copper strip will contact the compacting plate 461. The compacting plate 461 is squeezed by the copper strip and rotates a certain angle around the mounting shaft 466 through the connecting block 465. During this process, the torsion spring 468 is twisted to generate an elastic restoring force. After the copper strip passes through the compacting plate 461, the elastic restoring force of the torsion spring 468 causes the compacting plate 461 to quickly reset, exerting a certain pressure on the copper strip to compact the copper strip, so as to eliminate the gap in the copper strip and provide a The high density and strength of the product can avoid quality problems and make the product more sturdy and durable. At the same time, in order to ensure the stable position of the compacting plate 461, a mounting sleeve 463 is arranged on the outside of the mounting seat 462. The positioning block 464 inside the mounting sleeve 463 can play a certain limiting role on the compacting plate 461 under the action of the spring 2 467 to prevent the compacting plate 461 from excessive rotation. When the compacting plate 461 is subjected to a large external force impact, the positioning block 464 will absorb part of the impact force under the buffering effect of the spring 2 467 to protect the safe operation of the compacting mechanism 46. Through the action of the compacting mechanism 46, the copper strip can be effectively compacted in the cooling and shaping bin 44, further improving the quality and performance of the product.

[0059] like Fig. 9 As shown, the unloading assembly 6 includes a unloading bin 61 fixedly connected to the device base 1, the top of the unloading bin 61 is rotatably connected to a unloading roller 62, a servo motor 63 is fixedly installed on the outer wall of the unloading bin 61, and the output end of the servo motor 63 is fixedly connected to the unloading roller 62 through a coupling.

[0060] In actual application of the embodiment of the present invention, when the copper strip after a series of processing processes such as thermoplasticization, welding and cooling shaping enters the unloading component 6, the servo motor 2 63 is started and drives the unloading roller 62 to rotate through the coupling. The rotation of the unloading roller 62 can provide a stable support and conveying force for the copper strip, so that the copper strip can be discharged smoothly from the device.

[0061] The present invention provides another embodiment:

[0062] A copper strip extrusion method is now proposed, comprising the following steps:

[0063] Step 1: Place the copper strip on the support base 31 of the auxiliary component 3 and prepare for loading;

[0064] Step 2: Start the hydraulic cylinder 35 to push the movable seat 32 and the pressure roller 33 downward to apply pressure to the copper strip to ensure that the copper strip stably enters the loading bin 21;

[0065] Step 3: Start the servo motor 27 to drive the drive shaft 26 to rotate, and then the worm 25 drives the worm wheel 24 to rotate, so that the feeding roller 22 rotates evenly, and the copper strip smoothly enters the feeding bin 21 and is evenly cut by the cutting knife 23;

[0066] Step 4: The cut copper strip enters the thermoplastic extrusion chamber 41, the thermoplastic extrusion chamber 41 heats the copper strip, and the partition 42 guides the copper strip to accurately enter the thermoplastic forming chamber 43, where the copper strip is further heated and softened;

[0067] Step 5: The copper strip enters the cooling and shaping chamber 44 through the guide plate 45 and the shaping plate 47, and the compacting mechanism 46 outside the cooling and shaping chamber 44 compacts the copper strip;

[0068] Step 6: When the formed copper strip enters the welding assembly 5, the movable rod 54 is pushed downward to press the delay switch 55. The delay switch 55 controls the heating coil 53 to be energized to heat the cross-section of the copper strip. If there is subsequent copper strip feeding, welding between two sections of copper strip can be achieved. At the same time, the servo motor 2 63 is powered off, so that the subsequent copper strip can only push the previous copper strip to move, ensuring stable welding quality;

[0069] Step 7: When the heating coil 53 is powered on, the servo motor 2 63 is powered on, and the unloading assembly 6 is started, so that the copper strip is smoothly discharged from the unloading bin 61.

[0070] In combination with the above preferred embodiments, the working principle of the present invention is as follows:

[0071] First, the copper material is placed on the support seat 31 of the auxiliary component 3, and the hydraulic cylinder 35 is started. The telescopic end of the hydraulic cylinder 35 pushes the connecting sleeve 34, the movable seat 32 and the pressure roller 33 to move downward, and applies pressure to the copper strip to ensure that the copper strip stably enters the loading bin 21. The pressure sensor 36 detects the pressure in real time, and the spring 37 plays a buffering role;

[0072] After the copper strip enters the loading bin 21, it is transported forward with the assistance of the evenly rotating loading roller 22. At the same time, the servo motor 27 drives the driving shaft 26 to rotate. The worm 25 on the driving shaft 26 meshes with the worm wheel 24 at one end of the loading roller 22, so that the loading roller 22 rotates more smoothly. The copper strip is evenly divided by the dividing knife 23 in the loading bin 21.

[0073] The divided copper strips enter the thermoplastic extrusion chamber 41 of the thermoplastic assembly 4. The thermoplastic extrusion chamber 41 heats the copper strips to soften their outer sides, thereby reducing the difficulty of deformation and improving the efficiency and quality of thermoplastic processing. The partition plate 42 guides the copper strips to accurately enter the thermoplastic forming chamber 43. In the thermoplastic forming chamber 43, the copper strips are further heated and softened to enhance plasticity. Then, the copper strips pass through the guide plate 45 and the shaping plate 47 and enter the cooling shaping chamber 44. Under the action of the compacting mechanism 46, the copper strips are compacted to eliminate gaps and improve product density and strength.

[0074] When the formed copper strip enters the welding assembly 5, the movable rod 54 is pushed downward to press the delay switch 55, and the heating coil 53 is controlled to be energized to heat the cross-section of the copper strip. If there is subsequent copper strip feeding, welding between the two sections of copper strip can be achieved. The servo motor 2 63 is powered off so that the subsequent copper strip can only push the previous copper strip to move, ensuring stable welding quality. When the heating coil 53 is powered off and the servo motor 2 63 is powered on, the copper strip is stably discharged to the discharge bin 61 of the discharge assembly 6, and the servo motor 2 63 drives the discharge roller 62 to rotate, so that the copper strip can be discharged smoothly.
