Description

Technical Field

[0001] The present invention relates to the technical field of tungsten electrode filament forming, and particularly relates to a rapid forming device for tungsten electrode filaments. Background Art

[0002] A tungsten electrode filament is a filament made of tungsten and is usually used in fields such as lighting fixtures and electronic devices; common ones include tungsten-rhenium alloy wires, tungsten-molybdenum alloy wires, etc.; at the same time, when the tungsten electrode filament is applied to lighting fixtures, the common tungsten electrode filament will be wound during the production process into a spiral shape, and the filament can generate a higher temperature, thereby emitting a stronger light; and when the tungsten electrode filament is wound into a spiral shape, a winding machine is usually used to quickly form the tungsten electrode filament into a spiral shape.

[0003] However, the existing technology still has the following problems: First, although the winding machines for tungsten electrode filaments on the market currently have relatively high automation in feeding operation, winding operation, and discharging operation, after the tungsten electrode filament is wound on the winding rod, it needs to be detached from the winding rod. And on the market, the finished tungsten electrode filament formed into a spiral shape is directly pulled out from the winding rod. This method requires ensuring that the surface of the winding rod is smooth and requires continuous replenishment of lubricant. The maintenance time of this operation is relatively high, and when the lubricant is replenished on the surface of the winding rod, the lubricant is easily attached to the surface of the tungsten electrode filament, thereby affecting the quality and performance of the tungsten electrode filament. At the same time, when directly pulling out or pushing the tungsten electrode filament out of the winding rod, due to the tungsten electrode filament being closely attached to the surface of the winding rod, the generated frictional force is relatively large, and it is easy to cause damage to the surface of the tungsten electrode filament, thereby also affecting the quality and performance of the tungsten electrode filament. Therefore, we have proposed a rapid forming device for tungsten electrode filaments. Summary of the Invention

[0007] Further, the holding ring is composed of multiple holding blocks and a central column. A holding rod is fixedly installed in the middle of one side of the central column. The holding rod is correspondingly arranged opposite to the center of the anti-loosening mechanism.

[0009] Further, the anti-loosening mechanism includes a pushing plate.

[0011] Further, a groove is formed on one side inside the rotating ring, and another group of grooves are formed on the same side of multiple holding blocks. The two groups of grooves are arranged in a mutually fitting manner.

After the winding is completed and rotated to the designated position, it is convenient for the staff to remove it. Another polyurethane sponge sleeve can replace the original polyurethane sponge sleeve position and slide on the winding rod for work.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1 to 9 shown, a rapid prototyping device for tungsten filament includes: A forming table 6 and a wire guiding mechanism 3. The wire guiding mechanism 3 is arranged on the upper surface of the forming table 6, and a winding rod 4 is rotatably installed on the upper surface of the forming table 6, and the wire guiding mechanism 3 is used for docking the tungsten filament. An anti-scratching mechanism 1, which includes a polyurethane sponge sleeve 101 and a holding member 102. The polyurethane sponge sleeve 101 is slidably sleeved on the outer surface of the winding rod 4, and the polyurethane sponge sleeve 101 is formed into a cylinder through the holding member 102. Exemplarily, the above-mentioned polyurethane sponge sleeve 101 is a sponge treated specially (such as a sponge with high temperature resistance and corrosion resistance) It should be noted that due to the design of the polyurethane sponge sleeve 101 and its flexible wire, the polyurethane sponge sleeve 101 can use the winding rod 4 as a support mechanism to contact the tungsten electrode filament. After the tungsten electrode filament is wound into a spiral shape, the softness of the polyurethane sponge sleeve 101 makes it easier for the tungsten wire to slide when being pulled out. Especially after the winding is completed, the polyurethane sponge sleeve 101 can be pulled out together with the tungsten wire, reducing the resistance during the extraction process; Secondly, the softness and elasticity of the polyurethane sponge sleeve 101 can provide buffering between the tungsten wire and the winding rod 4, significantly reducing the direct friction between the tungsten wire and the surface of the winding rod 4, thereby reducing the risk of scratches and wear; And the polyurethane sponge sleeve 101 usually has a low cost and is easy to replace. If the surface of the winding rod 4 is worn or scratched, replacing the polyurethane sponge sleeve 101 is more economical than replacing the entire winding rod 4.

[0029] At the same time, the polyurethane sponge sleeve 101 can fill the tiny gaps or uneven parts that may exist on the surface of the winding rod 4, avoiding local stress concentration or scratches on the tungsten wire caused by these parts.

[0030] Exemplarily, the above-mentioned polyurethane sponge sleeve 101 can effectively protect the tungsten electrode filament for a long time due to its advantages of heat insulation, good wear resistance, strong aging resistance, and softness and good resilience.

[0031] The quick replacement mechanism 2, there are two sets of anti-scratch mechanisms 1, and the two sets of anti-scratch mechanisms 1 are both rotatably arranged in the same direction through the quick replacement mechanism 2; As Figures 1 to 9 shown, due to the design that the two sets of anti-scratch mechanisms 1 are both rotatably arranged in the same direction through the quick replacement mechanism 2, both sets of anti-scratch mechanisms 1 can be rotated by 90 degrees and replace positions with each other, so that the tungsten electrode filament wound on the first polyurethane sponge sleeve 101 can be vacated separately for removal, while the other polyurethane sponge sleeve 101 can be sleeved on the winding rod 4 for work. Therefore, by adopting the design of the quick replacement mechanism 2, it is possible to avoid generating an overly long downtime, resulting in a reduction in the forming efficiency of the tungsten electrode filament.

[0032] The auxiliary feeding mechanism 5, the auxiliary feeding mechanism 5 is arranged at one end of the upper surface of the forming table 6, and the holding mechanism approaches or moves away from one end of the winding rod 4 through the auxiliary feeding mechanism 5.

[0033] As Figures 1 to 9 shown, through the design of the auxiliary feeding mechanism 5, the polyurethane sponge sleeve 101 can be automatically pulled and sleeved on the winding rod 4, reducing the frequency of manual intervention, and therefore, reducing the labor cost to a certain extent and improving the replacement efficiency of the polyurethane sponge sleeve 101 on the winding rod 4; Further, the holding member 102 includes a first electromagnet ring 1022 and a holding ring. A polyurethane sponge sleeve 101 is disposed between the first electromagnet ring 1022 and the holding ring. An anti-loosening mechanism 7 is provided between the other end of the winding rod 4 and the holding ring. The polyurethane sponge sleeve 101 is slidably sleeved outside the winding rod 4 through the first electromagnet ring 1022. As Figures 1 to 9 shown, through the design of disposing the polyurethane sponge sleeve 101 between the first electromagnet ring 1022 and the holding ring, the polyurethane sponge sleeve 101 can maintain a hollow cylindrical shape, making it convenient to be sleeved on the winding rod 4, thereby avoiding excessive friction during the process of sleeving on the winding rod 4 due to the collapse inside the polyurethane sponge sleeve 101 and affecting its service life. Further, the holding ring is composed of multiple holding blocks 1023 and a central column 1026. A holding rod 1021 is fixedly installed in the middle of one side of the central column 1026. The holding rod 1021 is correspondingly arranged opposite to the center of the anti-loosening mechanism 7. An adjusting mechanism is provided inside the central column 1026, so that multiple holding blocks 1023 can approach or move away from the central column 1026 through the adjusting mechanism. As Figures 1 to 9 shown, through the design of multiple holding blocks 1023 and the central column 1026, multiple holding blocks 1023 can approach each other, causing one end of the polyurethane sponge sleeve 101 to shrink and deform, making it convenient to remove the tungsten electrode filament after winding and forming, thereby further improving the quality of the tungsten electrode filament after forming. Further, the adjusting mechanism includes a driving bevel gear 1028 and a driven bevel gear 1029. A rotating groove is formed inside the central column 1026, and the driving bevel gear 1028 is rotatably installed inside the rotating groove. Multiple adjusting grooves identical to the rotating groove are formed on the outside of the central column 1026, and the driven bevel gear 1029 is rotatably installed inside the adjusting groove. An adjusting screw rod 1025 is rotatably installed on the outside of the central column 1026 through the driven bevel gear 1029. An adjusting sleeve 1024 is threadedly sleeved on the outside of the adjusting screw rod 1025. The adjusting sleeve 1024 is fixedly connected to the holding block 1023, and the holding block 1023 is slidably connected to the central column 1026. Specifically, as Figures 1 to 9 shown, a telescopic rod 1027 is provided between the holding block 1023 and the central column 1026, so that when the holding block 1023 moves through the adjusting sleeve 1024 and the adjusting screw rod 1025, it is more stable and avoids rotation.

[0034] Further, the anti-loosening mechanism 7 includes a pushing plate 702. A pushing groove is formed at the other end of the winding rod 4, and a tightening spring 701 is fixedly installed at one end inside the pushing groove. One end of the tightening spring 701 is fixedly connected to the pushing plate 702, and the pushing plate 702 is slidably installed inside the pushing groove. The holding rod 1021 is correspondingly arranged opposite to the center of the pushing plate 702. As Figures 1 to 9 shown, through the design of the compression spring 701 and the push plate 702, the push plate 702 limits and jacks up the holding rod 1021, so that there is always a tensile force between the multiple holding blocks 1023 and the first electromagnet ring 1022, thus ensuring that the polyurethane sponge sleeve 101 always remains cylindrical. Therefore, it is possible to prevent the polyurethane sponge sleeve 101 from collapsing prematurely, causing the tungsten filament wound and formed to collide with the quick replacement mechanism 2 and damage its surface; Furthermore, the quick replacement mechanism 2 includes a carrier seat 201 and a rotating rod 205. The rotating rod 205 is rotatably installed on the upper surface of the carrier seat 201, and rotating rings 203 and support plates 204 are respectively and fixedly installed at both ends on both sides of the rotating rod 205. The holding block 1023 is located inside the rotating ring 203, and the first electromagnet ring 1022 is located inside the support plate 204; Specifically, as Figures 1 to 9 shown, a driving motor 202 is provided at one end of the upper surface of the carrier seat 201, and the output end of the driving motor 202 is key-connected to the rotating rod 205.

[0035] As Figures 1 to 9 shown, through the design that the first electromagnet ring 1022 is located inside the support plate 204 and the holding block 1023 is located inside the rotating ring 203, it is possible to ensure that the two polyurethane sponge sleeves 101 rotate and alternate on the upper surface of the carrier seat 201; Furthermore, a groove is formed on one side inside the rotating ring 203, and another group of grooves are formed on the same side of the multiple holding blocks 1023. The two groups of grooves are arranged in a mutually matching manner; As Figures 1 to 9 shown, through the design that the two groups of grooves are arranged in a mutually matching manner, the holding block 1023 can be more stably placed inside the rotating ring 203 by the mutual fitting of the two groups of grooves, and in cooperation with the support plate 204, the polyurethane sponge sleeve 101 is more stable outside the rotating rod 205; Specifically, as Figures 1 to 9 shown, the above-mentioned quick replacement mechanism 2 further includes a first rack 11 and a second rack 12. The other side of the central column 1026 is rotatably installed with a transmission gear 14 fixedly connected to a driving bevel gear 1028. The first rack 11 and the second rack 12 are both fixedly connected to the carrier seat 201, and the first rack 11 and the second rack 12 are respectively located on both sides of the rotating rod 205, and the transmission gear 14 is meshed with the inner side of the first rack 11, and the transmission gear 14 is meshed with the outer side of the second rack 12.

[0036] Through the design of the first rack 11 and the second rack 12, when the polyurethane sponge sleeve 101 just drawn out from the winding rod 4 rotates, it first meshes with the first rack 11, the transmission gear 14 rotates, controls the driving bevel gear 1028, and makes multiple groups of holding blocks 1023 approach each other, so as to achieve the shrinkage deformation at one end of the polyurethane sponge sleeve 101. Subsequently, the staff can manually press the central column 1026 to move multiple groups of holding blocks 1023 out of the inside of the rotating ring 203. Then, it is convenient to remove the wound tungsten filament. By using this method to remove, it can avoid the friction between the tungsten filament and the surface of the polyurethane sponge sleeve 101 during the removal process. Therefore, it can further improve the forming quality of the tungsten filament. It should be noted that when the polyurethane sponge sleeve 101 after removing the tungsten filament rotates to the position of the second rack 12, because the meshing directions of the first rack 11 and the second rack 12 with the transmission gear 14 are opposite, multiple groups of holding blocks 1023 can automatically reset when the transmission gear 14 meshes with the second rack 12. At the same time, under the action of the tightening spring 701 and without the manual intervention of the staff, multiple groups of holding blocks 1023 will automatically reset to the inside of the rotating ring 203. Therefore, the first rack 11 and the second rack 12 cooperate with the transmission gear 14 to quickly disassemble the tungsten filament without damage and automatically restore the polyurethane sponge sleeve 101 to a cylindrical state.

[0037] Furthermore, the auxiliary blanking mechanism 5 includes a lifting mechanism and a push rod 505. One end of the push rod 505 is arranged to lift above the winding rod 4 through the lifting mechanism. The other end of the push rod 505 is rotatably installed with a second electromagnet ring 506, and the second electromagnet ring 506 is slidably sleeved outside the winding rod 4. The lifting mechanism includes a side-mounted column 501, and the side-mounted column 501 is fixedly installed at one end of the upper surface of the forming table 6. A lifting lead screw 503 is rotatably installed on one side of the side-mounted column 501. A threaded block 504 is threadedly sleeved outside the lifting lead screw 503, and the threaded block 504 is slidably installed on one side of the side-mounted column 501. The threaded block 504 is rotatably connected to one end of the push rod 505. Specifically, as Figures 1 to 9 shown, a forward and reverse motor 502 for controlling the lifting lead screw 503 is arranged at the upper end of one side of the side-mounted column 501.

[0038] As Figures 1 to 9As shown, through the design of the first electromagnet ring 1022 and the second electromagnet ring 506, when the central axes of the first electromagnet ring 1022 on the polyurethane sponge sleeve 101 and the second electromagnet ring 506 are aligned, by supplying power to the first electromagnet ring 1022, the first electromagnet ring 1022 adheres to the second electromagnet ring 506. Subsequently, through the cooperation of the forward and reverse motor 502, the lifting lead screw 503, and the threaded block 504, the push rod 505 drives the second electromagnet ring 506 to adsorb the first electromagnet ring 1022, so as to pull the polyurethane sponge sleeve 101 to be sleeved on the winding rod 4, realizing the replacement of the polyurethane sponge sleeve 101 on the winding rod 4 without excessive manual intervention.

[0039] Exemplarily, the first electromagnet ring 1022 and the second electromagnet ring 506 in the above are both existing mature technologies, and those skilled in the art should know how to install and use the first electromagnet ring 1022 and the second electromagnet ring 506 to realize the adsorption or non-adsorption of the second electromagnet ring 506 to the first electromagnet ring 1022.

[0040] It should be noted that the first electromagnet ring 1022 in the above can be sleeved on the winding rod 4 through the second electromagnet ring 506 in a sliding manner.

[0041] Furthermore, a clamping groove 13 is formed inside the first electromagnet ring 1022, and the clamping groove 13 is triangular. A plurality of docking blocks 8 are elastically connected to one end of the outer side of the winding rod 4 close to the side mounting column 501. The docking blocks 8 are triangular, and the docking blocks 8 are clamped inside the clamping groove 13; Specifically, as Figures 1 to 9 shown, a plurality of sliding grooves 10 are formed at one end of the outer side of the winding rod 4 close to the side mounting column 501, and the lower ends of the docking blocks 8 are slidably installed inside the sliding grooves 10. A return spring 9 is fixedly installed at the bottom of the docking blocks 8, and one end of the return spring 9 is fixedly installed at one end inside the sliding grooves 10; Through the design of the triangular docking blocks 8 and the triangular clamping grooves 13, when the polyurethane sponge sleeve 101 is completely sleeved on the outer surface of the winding rod 4, the docking blocks 8 are clamped inside the clamping grooves 13, so that the winding rod 4 and the first electromagnet ring 1022 are fixed to each other, and the first electromagnet ring 1022 can rotate with the winding rod 4.

[0042] It should be noted that the opposite surfaces of the holding rod 1021 and the push plate 702 in the above can be made of high-friction materials. At the same time, the friction can also be increased by adding friction enhancers, so that when the push plate 702 rotates through the winding rod 4, it drives the holding rod 1021 to rotate, making the first electromagnet ring 1022 and a plurality of holding blocks 1023 rotate synchronously, realizing that the polyurethane sponge sleeve 101 can rotate with the winding rod 4 to complete the winding work of the tungsten electrode filament; The push plate 702 and the holding rod 1021 made of high-friction materials are tightly fitted to each other through the compact spring 701. Moreover, for the tungsten filament winding and forming device on the market, in order to ensure more stable forming of the tungsten filament, the rotation speed will not be too fast. Therefore, under the action of high friction and the compact spring 701, the rotation of the push plate 702 can drive the rotation of the holding rod 1021.

[0043] The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
