[0001] The present invention relates to the technical field of transmission equipment, and specifically to an automatic tungsten wire feeding device. Background Art

[0002] With the development of the demand for fine tungsten wires in modern high-precision processing fields and optical fields, the quality requirements and demand for tungsten wires in the market are also continuously increasing. In the traditional tungsten wire feeding process, manual operation or simple mechanical devices are mostly used, which have problems such as unstable wire feeding speed, inconsistent wire feeding length, and easy damage to tungsten wires, seriously affecting production efficiency and product quality. Especially in the fields of precision electronic device manufacturing, superalloy material processing, etc., the requirements for the precision and consistency of tungsten wires are extremely high, and the traditional wire feeding methods are difficult to meet the needs of modern industrial production. Therefore, it is particularly important to develop a device that can automatically, accurately, and continuously feed wires.

[0003] And due to process reasons, the processing speeds of annealing and swaging equipment for tungsten wires are inconsistent, and there is a problem that existing equipment cannot be directly linked. Summary of the Invention

[0032] The present invention provides a tungsten wire automatic feeding device. Compared with the prior art, it has the following advantages:

[0033] Beneficial effects:

[0034] 1. The tungsten wire automatic feeding equipment has an annealing tungsten wire receiving mechanism that is responsible for receiving the tungsten wire sent out after annealing. The wire feeding mechanism works in conjunction with the swaging wire feeding mechanism to feed the tungsten wire into the swaging equipment. The annealing wire output and swaging wire feeding are respectively arranged in two independent workstations, ensuring that the two steps with large differences in transmission speed do not interfere with each other. At the same time, a transfer mechanism is configured between the annealing tungsten wire receiving mechanism and the wire feeding mechanism to realize automatic switching of the tungsten wire workstations. The tungsten wire can be automatically switched between workstations. An abnormal wire output detection mechanism is also provided. For the tungsten wire that is bent and deformed after annealing, if it fails to be normally and completely transmitted to the annealing tungsten wire receiving mechanism, it can also be discharged independently for easy manual processing. The operation is convenient and the degree of automation is high.

[0035] 2. For this automatic tungsten wire feeding device, the annealing tungsten wire receiving mechanism uses rollers to receive the tungsten wire. Proximity switches are set at both ends to facilitate the automatic identification of the tungsten wire position. After the tungsten wire is transmitted in place, the transfer mechanism can be automatically started for transfer, eliminating the need for the transfer mechanism to be constantly started, thus saving power consumption. By setting the rollers into two separable parts and arranging an abnormal wire feeding detection mechanism below, when the tungsten wire bends below the rollers and squeezes and touches the elastic metal wire, an electrical signal is sent by changing the circuit current, causing the two parts of the rollers to separate. At this time, the abnormally transmitted tungsten wire can automatically fall and be received by the receiving piece. The electrical signal can also synchronously trigger an additional warning signal to facilitate notifying the staff for handling, which is relatively intelligent.

[0036] 3. For this automatic tungsten wire feeding device, the transfer mechanism body uses a chain to transfer the tungsten wire. By simply modifying the existing chain and extending the metal sheet on one side, a series of grooves can be formed on the chain surface to facilitate the accurate positioning and conveying of the tungsten wire. By setting a toggle rod on the side of a sprocket and cooperating with the push rod on the sprocket, when the chain starts to operate, the toggle rod can be automatically pushed to rotate to pick up the tungsten wire from the annealing tungsten wire receiving mechanism onto the chain. This design does not require an additional driving part, which not only reduces power consumption but also reduces the failure rate, greatly improving the usability.

[0037] 4. For this automatic tungsten wire feeding device, the swaging wire feeding mechanism uses two pairs of driving wheels to squeeze and push the tungsten wire into the swaging device. Between a pair of driving wheels close to the wire feeding receiving mechanism, a gap that slopes forward and upward is formed. Using this structure, for the tungsten wire that is transmitted and one end of which falls onto the second driving wheel, one end can automatically slide between the first driving wheel and the second driving wheel, and then can be automatically pushed and output to the right. There is no need to set a driving part for the wire feeding receiving mechanism to push the tungsten wire in, which reduces power consumption and can also avoid the problem that one end of the tungsten wire cannot slide into the swaging wire feeding mechanism and cannot be normally squeezed and transmitted. The structure is novel and easy to use. Description of the Drawings

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0055] The present invention provides four technical solutions:

[0056] Figures 1 - 2 The first embodiment is shown: an automatic tungsten wire feeding device, including a frame 1, which is mainly composed of square steel pipes welded to form a framework, and a plurality of U-shaped steels placed sideways are welded on the top. It also includes:

[0057] An annealed tungsten wire receiving mechanism 2, installed on the front side of the top of the frame 1, and the left end of the annealed tungsten wire receiving mechanism 2 is aligned with the wire outlet of the annealing device for receiving the tungsten wire sent out after annealing;

[0058] A wire feeding receiving mechanism 3, installed on the rear side of the top of the frame 1, for receiving the tungsten wire to be fed into the swaging device;

[0059] A transfer mechanism 4, for transferring the tungsten wire on the annealed tungsten wire receiving mechanism 2 to the wire feeding receiving mechanism 3;

[0060] A swaging wire feeding mechanism 5, installed at the right rear corner of the top of the frame 1 for pushing the tungsten wire on the wire feeding receiving mechanism 3 into the swaging device;

[0061] An abnormal wire outlet detection mechanism 6, installed on the annealed tungsten wire receiving mechanism 2, for detecting the tungsten wire that is not normally output due to deformation on the annealed tungsten wire receiving mechanism 2, and controlling the annealed tungsten wire receiving mechanism 2 to discharge the tungsten wire downward.

[0062] Both the annealed tungsten wire receiving mechanism 2 and the transfer mechanism 4 are installed on the U-shaped steel by welding or bolt installation methods, and the wire feeding receiving mechanism 3 and the swaging wire feeding mechanism 5 are directly installed on the square steel pipe framework.

[0063] The annealed tungsten wire receiving mechanism 2 is responsible for receiving the tungsten wire sent out after annealing. The wire feeding receiving mechanism 3 works in cooperation with the swaging wire feeding mechanism 5 to feed the tungsten wire into the swaging device. The annealing wire outlet and the swaging wire feeding are set at two independent workstations, ensuring that the two steps with a large difference in transmission speed do not interfere with each other. At the same time, a transfer mechanism 4 is configured between the annealed tungsten wire receiving mechanism 2 and the wire feeding receiving mechanism 3 to realize the automatic switching of the tungsten wire workstations. An abnormal wire outlet detection mechanism 6 is also provided. For the annealed and bent tungsten wire, if it fails to be normally and completely transmitted to the annealed tungsten wire receiving mechanism 2, it can be independently discharged for easy manual handling, with convenient operation and high automation.

[0064] Figures 3 - 5 The second embodiment is shown. The main difference from the first embodiment is that the annealed tungsten wire receiving mechanism 2 includes:

[0065] A front vertical plate 21 and a rear vertical plate 22, which are arranged in parallel and are both fixedly connected to the frame 1;

[0066] A sliding plate 23, slidably arranged on the rear side of the front vertical plate 21;

[0067] The first proximity switch 24 and the second proximity switch 25 respectively penetrate and are fixedly connected to both ends of the front vertical plate 21;

[0068] A plurality of electric push rods 26 are evenly and fixedly installed on the front side of the front vertical plate 21. The rear end of the electric push rod 26 is connected to the sliding plate 23 through a push-pull frame 27;

[0069] A plurality of front half-wheels 28 and rear half-wheels 29 are respectively rotatably connected at equal intervals on the opposite surfaces of the sliding plate 23 and the rear vertical plate 22. A prism shaft 291 is provided on the front side of the rear half-wheel 29, and a prism groove 281 adapted to the prism shaft 210 is provided on the rear side of the front half-wheel 28. When the front half-wheel 28 and the rear half-wheel 29 are butted, they form a roller that is thin in the middle and thick at both ends.

[0070] The abnormal wire feeding detection mechanism 6 includes:

[0071] A detection tube 61 is fixedly installed on the front side of the rear vertical plate 22 and is located below the rear half-wheel 29;

[0072] Elastic metal wires 62 are arranged side by side on the top of the detection tube 61. Two resistance wires connected to the same power supply are arranged in the detection tube 61. Adjacent elastic metal wires 62 are respectively connected to the two resistance wires. When the tungsten wire breaks away from the roller and bends downward to squeeze the adjacent elastic metal wires 62, the current on the resistance wire changes, and whether the tungsten wire squeezes the elastic metal wires 62 is judged by the current change;

[0073] A plurality of receiving pieces 63 are arranged side by side and fixedly connected to the frame 1. The receiving pieces 63 are located below the rear vertical plate 22.

[0074] The annealing tungsten wire receiving mechanism 2 uses rollers to receive the tungsten wire. Proximity switches are provided at both ends to facilitate automatic identification of the tungsten wire position. After the tungsten wire is transferred in place, the transfer mechanism 4 can be automatically started for transfer, without the transfer mechanism 4 being constantly started, saving power consumption; and by setting the roller into two separable parts and arranging an abnormal wire feeding detection mechanism 6 below, when the tungsten wire bends below the roller and squeezes and touches the elastic metal wires 62, an electrical signal is sent by changing the circuit current, causing the two parts of the roller to separate. At this time, the abnormally transmitted tungsten wire can automatically fall and be received by the receiving pieces 63. The electrical signal can also trigger an additional warning signal synchronously, facilitating notification to the staff for handling, which is relatively intelligent.

[0075] Figure 6 The third embodiment is shown. The main difference from the first embodiment is that the transfer mechanism 4 includes:

[0076] Two connecting shafts 41 are provided and are rotatably connected in parallel to the top of the frame 1 through bearing seats;

[0077] A plurality of rows of sprockets 42 are provided and are respectively fixedly connected to the two connecting shafts 41;

[0078] The chain 43 is drivingly connected to two sprockets 42 in the same row. The chain links on one side of the chain 43 extend outward for limiting and transporting the tungsten wire.

[0079] The shifting rod 44 is arranged on one side of the sprocket 42, and one end thereof extends to the inside of the annealing tungsten wire receiving mechanism 2 for shifting the tungsten wire on the annealing tungsten wire receiving mechanism 2 onto the chain 43.

[0080] At the rear side of the right end of the frame 1, a first motor 45 is fixedly connected. The output end of the first motor 45 is in meshing transmission with the rear connecting shaft 41 through a pair of bevel gears 46.

[0081] On the frame 1 and on one side of the sprocket 42, an L-shaped mounting plate 47 is fixedly connected. The shifting rod 44 includes a wire shifting section 441 and a pushing section 442 connected to one end thereof. At the connection of the wire shifting section 441 and the pushing section 442, a rotating shaft section 443 extends laterally. The rotating shaft section 443 is rotatably connected through the L-shaped mounting plate 47. At the top of the rear vertical plate 22, a notch adapted to the wire shifting section 441 is provided. On one side of the front sprocket 42, a push rod 48 is provided, and a sleeve 49 is rotatably sleeved outside the push rod 48. Rotatably sleeving the sleeve 49 can reduce the friction force, making the push rod 48 push the shifting rod 44 more smoothly. When the sprocket 42 drives the push rod 48 to rotate, the pushing section 442 is pushed through the sleeve 49 to make the wire shifting section 441 rotate around the rotating shaft section 443 as the axis.

[0082] The main body of the transfer mechanism 4 uses the chain 43 to transfer the tungsten wire. By simply modifying the existing chain 43 and extending the metal sheet on one side, a series of channels can be formed on the surface of the chain 43, which is convenient for accurately positioning and transporting the tungsten wire. By arranging the shifting rod 44 on one side of a sprocket 42 and cooperating with the push rod 48 on the sprocket 42, when the chain 43 starts to operate, the shifting rod 44 can be automatically pushed to rotate to shift the tungsten wire from the annealing tungsten wire receiving mechanism 2 onto the chain 43. This design does not require an additional driving part, which not only reduces the power consumption but also reduces the failure rate, greatly improving the use convenience.

[0083] Figures 7 - 10 The fourth embodiment is shown. The main difference from the first embodiment is that: the wire feeding receiving mechanism 3 includes a plurality of wheel frames 31 fixedly connected to the frame 1, and a receiving wheel 32 is rotatably connected to the wheel frames 31. The front top of the wheel frames 31 is bent forward and inclined. The inclined setting can play a guiding role and facilitate the tungsten wire to accurately fall onto the receiving wheel 32.

[0084] The rotary swaging wire feeding mechanism 5 includes a transmission box 51 installed on the frame 1 by bolts. The front side of the transmission box 51 is rotatably connected to the first drive wheel 52, the second drive wheel 53, the third drive wheel 54 and the fourth drive wheel 55. The rear ends of the first drive wheel 52 and the second drive wheel 53 and the rear ends of the third drive wheel 54 and the fourth drive wheel 55 are all meshed and transmitted through gears 56. The rear ends of the first drive wheel 52 and the third drive wheel 54 are fixedly connected with pulleys 57, and the two pulleys 57 are connected by belts 58. The rear side of the transmission box 51 is fixedly connected to the second motor 59, and the output end of the second motor 59 is fixed to the rear end of the second drive wheel 53.

[0085] The surfaces of the first drive wheel 52, the second drive wheel 53, the third drive wheel 54 and the fourth drive wheel 55 are all covered with anti-slip rubber rings 510. The diameter of the front half of the first drive wheel 52 gradually decreases, and the diameter of the front half of the second drive wheel 53 gradually increases. The front end of the second drive wheel 53 extends beyond the front end of the first drive wheel 52, and the distance between the front halves of the first drive wheel 52 and the second drive wheel 53 gradually increases.

[0086] The rotary forging wire feeding mechanism 5 utilizes two pairs of driving wheels to extrude and push the tungsten wire into the rotary forging equipment, and a gap inclined forward and upward is formed between the pair of driving wheels close to the wire feeding receiving mechanism 3. With this structure, the tungsten wire that is transmitted and one end falls on the second driving wheel 53 can automatically slide one end between the first driving wheel 52 and the second driving wheel 53, and then can be automatically pushed to the right for output. There is no need to set a driving part for the wire feeding receiving mechanism 3 to push the tungsten wire, which reduces power consumption and avoids the problem that one end of the tungsten wire cannot slide into the rotary forging wire feeding mechanism 5 and cannot be extruded and transmitted normally. The structure is novel and easy to use.

[0087] At the same time, the contents not described in detail in this manual belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used. Each electrical appliance is connected to a computer via a wire and controlled by a program.

[0088] During use, the tungsten wire discharged from the annealing equipment falls onto the roller composed of the front half wheel 28 and the rear half wheel 29, and is gradually pushed to the right. The right end of the tungsten wire passes through the sensing range of the first proximity switch 24 and the second proximity switch 25 in succession. Through the two sensings, it is determined that the tungsten wire is transmitted and is completely transmitted to the roller. It is determined that a tungsten wire has been completely withdrawn, and then the transfer mechanism 4 and the rotary forging wire feeding mechanism 5 are started.

[0089] When the tungsten wire is output and the right end is inserted under the roller due to fullness, the tungsten wire will gradually press against the elastic wire 62, and the circuit current of the resistance wire connected thereto will change, triggering an electric signal to control the electric push rod 26 to pull the push-pull frame 27 and the front vertical plate 21 forward, separating the front half wheel 28 from the rear half wheel 29, and then causing the tungsten wire to fall onto the receiving piece 63.

[0090] When the transfer mechanism 4 is started, the first motor 45 drives the coupling shaft 41 to rotate through the bevel gear 46, and then drives the sprocket 42 to rotate and drive the chain 43. When the front sprocket 42 rotates, it pushes the toggle rod 44 to rotate through the push rod 48 and the sleeve 49, and then pushes the tungsten wire backward onto the chain 43, and then is driven backward by the chain 43 until it slides onto the receiving wheel 32.

[0091] At the same time as the tungsten wire slides onto the receiving wheel 32, its right end will fall onto the second driving wheel 53 and slide along the slope of the second driving wheel 53 to between the first driving wheel 52 and the second driving wheel 53. The second motor 59 drives the second driving wheel 53 to rotate, and through the transmission of the gear 56, the pulley 57, and the belt 58, the four driving wheels rotate together, squeezing the tungsten wire in the middle and pushing it to the right until it is pushed into the rotary forging equipment.

[0092] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0093] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
