Abstract
Description
Technical Field
[0001] The present application relates to the technical field of precious metal processing, and in particular to a batch processing technology and processing equipment for gold ear needles with anti-slip grooves. Background Art
[0002] In the processing of gold ear needles, gold wire is a key raw material, and its straightening effect has a decisive influence on the quality of the ear needles. Straight gold wire can not only ensure the accurate shape of the ear needles, but also improve their mechanical strength and surface texture, making the ear needles more comfortable to wear and more beautiful in appearance. As consumers' requirements for the quality of gold ear needles continue to rise, efficient and accurate gold wire straightening technology has become a key factor in improving the processing quality of gold ear needles.
[0003] The equipment used in gold ear needle processing mainly includes cutting devices, straightening devices and propulsion devices, which work together to complete the processing process. The straightening device is responsible for straightening the curled gold wire at the front end of the equipment, which makes it easier to process grooves and cut the gold wire after straightening; there are many technologies for straightening devices. Roller straightening technology uses a set of rollers to adjust the roller spacing and pressure to allow the gold wire to roll between the rollers, relying on friction and extrusion to achieve straightening; rotary straightening technology uses a rotating part with a through hole, the gold wire passes through the through hole, and the rotating part rotates continuously, using extrusion forces in different directions to straighten the bent gold wire.
[0004] However, these existing technologies have many defects. The gold wire is not straight, which will lead to inconsistent groove depth and even breakage during the grooving process. In the roller straightening technology, the contact area between the roller and the gold wire is small, which is easy to leave indentations and scratches on the surface of the gold wire; the equipment of the rotary straightening technology squeezes the gold wire in multiple directions. When the gold wire with multiple curvatures enters the through hole of the rotating device, the gold wire of the rotating device can only be squeezed at a single point with the area with a larger curvature of the gold wire, and the straightening effect is not good. The single-point squeezing force will cause the gold wire to be subjected to greater stress and deform. Increasing the contact surface area with the gold wire to obtain a better straightening effect will cause the gold wire to soften due to the high temperature of the high-speed rotation of the rotating device. When the propulsion mechanism pushes, the softened gold wire is easy to deform or even break. Therefore, there is a need for a batch processing equipment for gold ear needles that can better straighten the gold wire and prevent the gold wire from overheating to solve the above problems. Summary of the invention
[0005] In view of this, it is necessary to provide a batch processing device for gold ear needles that can better straighten the gold wire and prevent the gold wire temperature from being too high, so as to solve the above problems.

[0017] The oil dripping mechanism further includes a second elastic diaphragm for blocking the oil replenishing hole. The second elastic diaphragm includes a plurality of second membranes arranged around the oil replenishing hole. Each second membrane has a second curved surface inclined in the opening direction of the oil replenishing hole, and each second curved surface abuts against each other to prevent the lubricating oil in the flexible oil storage member from entering the oil replenishing cavity.
[0018] When the straightening mechanism stops rotating, a negative pressure is formed in the flexible oil storage member, and the lubricating oil enters the flexible oil storage member through the second elastic diaphragm.
[0019] In at least one embodiment of the present application, the spiral extrusion portion has an extrusion surface and arc surfaces arranged on both sides of the extrusion surface. The oil dripping micro-holes are sequentially opened on the extrusion surface along the opening direction of the first straightening hole, and are used for the lubricating oil to directly contact the gold wire when the oil dripping mechanism drips oil.

[0026] The embodiment of the present application provides a batch processing process for gold ear pins, which is applied to the batch processing equipment for gold ear pins as described above. The batch processing process for gold ear pins further includes the steps:
[0027] The gold wire passes through the guiding mechanism and enters the straightening mechanism, and the straightening mechanism rotates to straighten the gold wire.
[0028] The straightening mechanism rotates to drive the oil dripping mechanism to drip lubricating oil onto the gold wire, so as to reduce the friction force when the straightening mechanism straightens the gold wire;
[0029] The pushing mechanism pushes the straightened gold wire to move to the cutting mechanism for cutting to obtain a finished ear needle.
[0030] The batch processing equipment for gold ear needles provided above has at least the following beneficial effects:
[0031] 1. The straightening mechanism enables the gold wire to maintain a straight output through the straightening hole opened at the axis. The spiral extrusion part is spirally arranged on the straightening part and located in the straightening hole. When the gold wire extends into the straightening hole through the guide mechanism, the spiral extrusion part can exert force on the gold wire from multiple directions. The spiral extrusion method can better adapt to the multi-curvature shape of the gold wire and increase the contact area with the gold wire, so that the gold wire can be better straightened during the rotation process; during the straightening process, the oil dripping mechanism attaches oil to the gold wire to form a lubricating film, which greatly reduces the friction coefficient and reduces the heat generation. The lubricating oil also has a cooling effect, which significantly improves the straightening effect of the gold wire.
[0032] 2. The setting of the elastic diaphragm and the pushing member in the oil dripping mechanism. During the rotation of the rotating mechanism, the pushing member squeezes the flexible oil storage member due to the centrifugal force, and the volume of the flexible oil storage member is reduced, squeezing the lubricating oil into the oil dripping micropores through the elastic diaphragm. When the rotating mechanism stops rotating, the pushing member stops squeezing the flexible oil storage member. The elastic diaphragms are elastic and abut against each other to close to prevent the leakage of the lubricating oil when the rotating mechanism is not working. After the lubricating oil in the flexible oil storage member is reduced, the internal state becomes a negative pressure state, and the elastic diaphragm in the oil replenishing chamber is subjected to the force of negative pressure to replenish the lubricating oil in the oil storage tank into the flexible oil storage member. After the replenishment is completed, the second elastic diaphragm is closed to prevent the lubricating oil from flowing back.
[0033] 3. The straightening holes with decreasing apertures can gradually reduce the curvature of the gold wire. The multiple straightening parts arranged in sequence can straighten the gold wire multiple times. The multiple straightening parts are arranged at intervals. When passing through a straightening part, the gold wire will be in the interval. The interval exposed to the air will accelerate the heat dissipation of the gold wire, and prevent the continuous straightening from causing continuous heating when entering the next straightening part. Because the gold wire will be grooved, the gold wire will be moved in an orderly manner by the pushing mechanism for a distance and then paused, waiting for the groove cutting and cutting processing. The length of the straightening hole is set to be greater than or equal to the length of each displacement of the gold wire, which can effectively prevent the situation where the gold wire cannot be straightened due to the interval setting.

[0046] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0047] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time.

[0048] The embodiment of the present application provides a batch processing device for gold ear needles with anti-slip grooves, comprising a base and a guide mechanism and a propulsion mechanism arranged on the base, and the processing device also includes:
[0049] A straightening mechanism is rotatably disposed between the guide mechanism and the propulsion mechanism, the straightening mechanism is provided with a first straightening hole along its axis, the gold wire is extended into the first straightening hole through the guide mechanism, the straightening mechanism comprises an integrally formed first straightening portion and a spiral extrusion portion, the first straightening hole is provided on the first straightening portion, the spiral extrusion portion is spirally disposed on the first straightening portion and is located in the first straightening hole;
[0050] An oil dripping mechanism, wherein the first straightening portion is provided with an oil storage cavity, and the spiral extrusion portion is provided with an oil dripping microhole with a diameter of 0.4mm-0.8mm which is connected to the oil storage cavity. The oil dripping mechanism is arranged in the oil storage cavity, and is used for flowing the lubricating oil through the oil storage cavity and the oil dripping microhole into the gold wire.
[0051] The straightening mechanism enables the gold wire to maintain a straight output through a straightening hole opened at the axis, and the spiral extrusion part is spirally arranged on the straightening part and located in the straightening hole. When the gold wire extends into the straightening hole through the guide mechanism, the spiral extrusion part can exert force on the gold wire from multiple directions. The spiral extrusion method can better adapt to the multi-curvature shape of the gold wire and increase the contact area with the gold wire, so that the gold wire can be better straightened during the rotation process; during the straightening process, the oil dripping mechanism attaches oil to the gold wire to form a lubricating film, which greatly reduces the friction coefficient and reduces the heat generation. The lubricating oil also has a cooling effect, which significantly improves the straightening effect of the gold wire.
[0052] The elastic diaphragm and the pushing member in the oil dripping mechanism are arranged such that, during the rotation of the rotating mechanism, the pushing member squeezes the flexible oil storage member due to the centrifugal force, and the volume of the flexible oil storage member is reduced, squeezing the lubricating oil into the oil dripping micropores through the elastic diaphragm; when the rotating mechanism stops rotating, the pushing member stops squeezing the flexible oil storage member, and the elastic diaphragms are elastic and abut against each other to close to prevent the leakage of the lubricating oil when the rotating mechanism is not working; after the lubricating oil in the flexible oil storage member is reduced, the internal state becomes a negative pressure state, and the elastic diaphragm in the oil replenishing chamber is subjected to the force of the negative pressure to replenish the lubricating oil in the oil storage tank into the flexible oil storage member, and after the replenishment is completed, the second elastic diaphragm is closed to prevent the lubricating oil from flowing back.
[0053] The straightening holes with successively decreasing apertures can gradually reduce the curvature of the gold wire. The multiple straightening parts arranged in sequence can straighten the gold wire multiple times. The multiple straightening parts are arranged at intervals. When passing through a straightening part, the gold wire will be in the interval. The interval exposed to the air will accelerate the heat dissipation of the gold wire, and prevent continuous straightening from causing continuous heating when entering the next straightening part. Because the gold wire will undergo grooving, the gold wire will be moved in an orderly manner by the pushing mechanism for a distance and then paused, waiting for grooving and cutting. The length of the straightening hole is set to be greater than or equal to the length of each displacement of the gold wire, which can effectively prevent the situation where the gold wire cannot be straightened due to the interval setting.
[0054] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0055] See also Figure 1-Figure 10 The embodiment of the present application provides a batch processing technology and processing equipment for gold ear needles with anti-slip grooves, including a base and a guide mechanism and a propulsion mechanism arranged on the base, and the processing equipment also includes:
[0056] A straightening mechanism 10 is rotatably disposed between the guide mechanism and the propulsion mechanism. The straightening mechanism 10 is provided with a first straightening hole 13 along its axis. The gold wire 40 extends into the first straightening hole 13 through the guide mechanism. The straightening mechanism 10 includes an integrally formed first straightening portion 11 and a spiral extrusion portion 12. The first straightening hole 13 is provided on the first straightening portion 11. The spiral extrusion portion 12 is spirally disposed on the first straightening portion 11 and is located in the first straightening hole 13.
[0057] The oil dripping mechanism 20, the first straightening part 11 is provided with an oil storage cavity 111, the spiral extrusion part 12 is provided with an oil dripping microhole 21 with a diameter of 0.4mm-0.8mm which is connected to the oil storage cavity 111, the oil dripping mechanism 20 is arranged in the oil storage cavity 111, and is used for flowing the lubricating oil through the oil storage cavity 111 and the oil dripping microhole 21 into the gold wire 40.
[0058] Specifically, the base provides support and stability for the equipment and is the foundation of the entire processing equipment. The guide mechanism accurately guides the gold wire 40 into the next processing step. It ensures the smooth passage of the gold wire 40 and prevents the gold wire 40 from being offset or deviated. The propulsion mechanism propels the gold wire 40 during the processing so that the gold wire 40 passes through each processing unit in an orderly manner, ensuring that the gold wire 40 can enter the subsequent steps continuously and stably. The gold wire 40 enters the hole through the guide mechanism and is straightened. The spiral extrusion part 12 is designed to be in a spiral shape, and the spiral structure can apply uniform pressure to straighten the gold wire 40 during rotation, ensuring that the gold wire 40 has a higher straightness.
[0059] Furthermore, the one-piece design of the first straightening part 11 and the spiral extrusion part 12 ensures zero error in the transmission of the equipment during the rotation process, avoiding idling during the straightening process. The design of the spiral extrusion part 12 can apply pressure evenly, avoiding damage to the gold wire 40 due to local uneven force in traditional straightening methods, thereby improving the processing effect and the quality of the gold wire 40.
[0060] Furthermore, the spiral extrusion part 12 is composed of a plurality of spiral rings, and a certain gap is left between each spiral ring. The function of these gaps is to allow the gold wire 40 to pass through these spiral rings and enter the straightening hole. The gold wire 40 itself has a subtle multi-radian wavy bend and will bend due to traction and pressure, and some parts with larger curvature will enter these gaps. During the straightening process, the gold wire 40 will be subjected to a certain pressure and extrusion, and these pressures and extrusions are generated by the rotation of the spiral extrusion part 12. Due to the particularity of its shape, the curved part with a larger curvature will enter the gap when the gold wire 40 passes through the spiral extrusion part 12. As the spiral extrusion part 12 rotates, the gap of the spiral ring gradually shrinks, thereby correcting these parts of the gold wire 40 with larger curvature. The rotation of the spiral extrusion part 12 gradually straightens the bend of the gold wire 40 with a larger curvature.
[0061] Furthermore, the design of the spiral extrusion part 12 can accurately correct the area with relatively large curvature in the gold wire 40. The curvature of the gold wire 40 is often uneven, and the setting of the spiral extrusion part 12 can perform targeted straightening for parts with different curvatures, making the overall straightness of the gold wire 40 more uniform and reducing the situation of local over-correction or under-correction.
[0062] Furthermore, the oil dripping microhole 21 controls the flow of lubricating oil through its small aperture, ensuring that the oil can be accurately dripped onto the surface of the gold wire 40 when the gold wire 40 passes through the straightening mechanism 10, reducing friction and improving the straightening effect. The lubricating oil can reduce the friction between the gold wire 40 and the straightening component, thereby achieving a more efficient straightening process and preventing the gold wire 40 from being damaged due to excessive friction.
[0063] Furthermore, the size of the oil dripping microhole 21 determines the amount of oil dripped each time. Too small an aperture will result in too low a flow rate of lubricating oil, which will not be able to effectively lubricate the gold wire 40, thereby affecting the straightening effect. Too large an aperture may result in too much flow of lubricating oil, causing oil stains on the surface of the gold wire 40, and even affecting the surface finish of the gold wire 40. The size of 0.4mm-0.8mm can control the amount of lubricating oil within a reasonable range while ensuring sufficient lubrication. This size can effectively avoid excessive dripping of lubricating oil, while ensuring that the gold wire 40 is sufficiently lubricated and will not cause jamming or irregular deformation due to excessive friction.
[0064] In a specific embodiment, the oil dripping mechanism 20 includes a flexible oil storage member 22 and a pushing member 23 disposed in the oil storage chamber 111;
[0065] The pushing member 23 is disposed at one end of the oil storage chamber 111 close to the spiral extrusion portion 12 and is movably connected to the oil storage chamber 111. The flexible oil storage member 22 is disposed at one end of the oil storage chamber 111 away from the spiral extrusion portion 12 and abuts against the pushing member 23. The flexible oil storage member 22 is connected to the oil dripping micropore 21.
[0066] When the straightening mechanism 10 starts to rotate, the pusher 23 is subjected to centrifugal force to squeeze the flexible oil storage member 22 so as to squeeze the lubricating oil into the oil dripping micropores 21 .
[0067] Specifically, the flexible oil storage member 22 is equivalent to a small oil bag, which can reduce the volatilization and leakage of the lubricating oil and ensure the storage stability of the lubricating oil. When the straightening mechanism 10 rotates, the pusher 23 will be subjected to the centrifugal force and squeeze the flexible oil storage member 22 outward, so that the lubricating oil flows into the oil dripping micropores 21. The centrifugal force generated during the rotation process is used to continuously squeeze the flexible oil storage member 22, thereby realizing the automatic supply of lubricating oil without the need for an additional power device. The movable connection design of the pusher 23 makes the supply of lubricating oil more continuous and uniform, and there will be no intermittent dripping of oil or excessive oil supply.
[0068] In a specific embodiment, the pushing member 23 includes a pushing portion 231 and an elastic portion 232, two ends of the elastic portion 232 are respectively arranged on the pushing portion 231 and the first straightening portion 11, and the pushing portion 231 abuts against the flexible oil storage member 22;
[0069] The projection of the pushing member 23 along a direction perpendicular to the central axis of the first straightening hole 13 and the projection of the oil dripping micro hole 21 along a direction perpendicular to the central axis of the first straightening hole 13 are staggered with each other.
[0070] Specifically, the pushing portion 231 is the main part of the pushing member 23, which directly abuts against the flexible oil storage member 22 and squeezes the flexible oil storage member 22 under the action of centrifugal force, thereby realizing the supply of lubricating oil. The two ends of the elastic portion 232 are respectively fixed on the pushing portion 231 and the first straightening portion 11 to provide elastic support for the pushing member 23. When the pushing member 23 moves under the action of centrifugal force, the elastic portion 232 will deform, adjust the movement trajectory of the pushing portion 231, and make the supply of lubricating oil more uniform and controllable. When the centrifugal force decreases (such as when the equipment stops rotating), the elastic portion 232 will return to its original state, so that the pushing portion 231 returns to its initial position to prevent the continuous dripping of lubricating oil.
[0071] Furthermore, the pusher 231 squeezes the flexible oil storage member 22 under the action of centrifugal force, but when the rotation stops, the elastic part 232 can return the pusher 23 to its original position, avoiding the outflow of excess lubricating oil and improving the efficiency of lubricating oil use. The oil dripping micropores 21 are used to drip the lubricating oil evenly on the gold wire 40, while the pusher 23 is used to control the supply of lubricating oil. The projections of the two perpendicular to the axis of the straightening hole are staggered to prevent the lubricating oil from being directly interfered by the pusher 23. Through the staggered design, the lubricating oil can flow out stably without physical interference from the pusher 23, thereby ensuring lubrication uniformity.
[0072] In a specific embodiment, the flexible oil storage member 22 includes an oil storage portion 221 and a first elastic diaphragm 222 disposed on the oil storage portion 221, the pushing portion 231 abuts against the oil storage portion 221, and the first elastic diaphragm 222 blocks the oil dripping micropore 21;
[0073] The first elastic diaphragm 222 includes a plurality of first membranes 222a arranged in a ring on the oil dripping micropore 21, each of the first membranes 222a has a first curved surface 222a1 inclined along the opening direction of the oil dripping micropore 21, and each of the first curved surfaces 222a1 abuts against each other to prevent the lubricating oil from dripping into the oil dripping micropore 21 due to gravity.
[0074] Specifically, the first elastic diaphragm 222 covers the oil dripping micropore 21 to prevent the lubricating oil from flowing out in a non-working state. When the oil storage portion 221 is pressurized, the first elastic diaphragm 222 is deformed to allow the lubricating oil to pass through the oil dripping micropore 21 to achieve precise oil dripping.
[0075] Furthermore, a plurality of first membranes 222a surround the oil dripping micropores 21 to form a dynamic sealing structure. Each first membrane 222a has an inclined first curved surface 222a1, which abut against each other to ensure that the lubricating oil will not drip out naturally when there is no external force. The first curved surfaces 222a1 abut against each other to form an "umbrella-shaped" sealing structure, so that the lubricating oil cannot break through the closed state by its own gravity. Even if the oil storage portion 221 is full of lubricating oil, due to the curved surface structure of the first membrane 222a, the oil will not seep out due to gravity. Only when the pushing portion 231 applies sufficient pressure to the oil storage portion 221, the first membrane 222a will be partially deformed to allow the lubricating oil to pass through.
[0076] In a specific embodiment, the first straightening portion 11 is provided with an oil replenishing cavity 112 arranged in parallel with the oil storage cavity 111, and the oil replenishing cavity 112 is provided with an oil replenishing hole 112a connected to the flexible oil storage member 22;
[0077] The oil dripping mechanism 20 further includes a second elastic diaphragm 24 that blocks the oil replenishing hole 112a. The second elastic diaphragm 24 includes a plurality of second membranes 241 that are arranged around the oil replenishing hole 112a. Each of the second membranes 241 has a second curved surface 241a that is inclined along the opening direction of the oil replenishing hole 112a. Each of the second curved surfaces 241a abuts against each other to prevent the lubricating oil in the flexible oil storage member 22 from entering the oil replenishing chamber 112.
[0078] When the straightening mechanism 10 stops rotating, negative pressure is formed in the flexible oil storage member 22 , and the lubricating oil enters the flexible oil storage member 22 through the second elastic diaphragm 24 .
[0079] Specifically, the oil replenishing chamber 112 is an independent chamber arranged in parallel with the oil storage chamber 111, and serves as the oil source of the flexible oil storage member 22 to ensure that the lubricating oil can be automatically replenished after consumption. It is connected to the oil replenishing hole 112a to realize the flow of lubricating oil to the flexible oil storage member 22, so that the lubricating oil is always maintained at a reasonable level. The second elastic diaphragm 24 blocks the oil replenishing hole 112a, and its structure is similar to that of the first elastic diaphragm 222. It is composed of a plurality of second membranes 241 and is arranged in a ring on the oil replenishing hole 112a. Each second membrane 241 has a second curved surface 241a inclined along the opening direction of the oil replenishing hole 112a, and these second curved surfaces 241a abut against each other to form a sealing structure.
[0080] Furthermore, the straightening mechanism 10 rotates at high speed, the pushing part 231 squeezes the flexible oil storage part 22, and the lubricating oil is supplied to the straightening part through the first elastic diaphragm 222. At this time, the lubricating oil in the oil replenishing chamber 112 remains stationary, and the second elastic diaphragm 24 closes the oil replenishing hole 112a to prevent the lubricating oil from entering the flexible oil storage part 22. When the straightening mechanism 10 stops rotating, the pushing part 231 stops squeezing the flexible oil storage part 22. The volume of the flexible oil storage part 22 is restored, resulting in negative pressure inside it, forming an oil suction force. The negative pressure causes the second membrane 241 of the second elastic diaphragm 24 to deform, and the oil dripping micropore 21 is briefly opened. The lubricating oil in the oil replenishing chamber 112 flows into the flexible oil storage part 22 along the oil replenishing hole 112a until the internal pressure is balanced. The oil replenishment is completed, and the second elastic diaphragm 24 is closed again.
[0081] In a specific embodiment, the spiral extrusion portion 12 has an extrusion surface 121 and arc surfaces 122 arranged on both sides of the extrusion surface 121, and the oil dripping microholes 21 are sequentially opened on the extrusion surface 121 along the opening direction of the first straightening hole 13, so that the lubricating oil directly contacts the gold wire 40 when the oil dripping mechanism 20 drips oil.
[0082] Specifically, the extrusion surface 121 is the area where the spiral extrusion part 12 directly contacts the gold wire 40, which is used to apply straightening force to the gold wire 40. At the same time, it is provided with oil dripping microholes 21 so that the lubricating oil can act accurately on the extrusion point. The arc surface 122 is located on both sides of the extrusion surface 121, guiding the gold wire 40 to smoothly enter the extrusion surface 121 during the straightening process to prevent the gold wire 40 from breaking or being damaged due to severe deformation. The transition through the arc surface 122 reduces the sudden force change of the gold wire 40, ensuring a smooth straightening process. The lubricating oil is evenly distributed throughout the straightening process in sequence along the straightening direction to ensure continuous lubrication.
[0083] In a specific embodiment, the first straightening hole 13 has a first aperture and a second aperture along the moving direction of the gold wire 40, and the first aperture is larger than the second aperture;
[0084] The single moving distance of the gold wire 40 is defined as a, and the length of the first straightening hole 13 is defined as b, where b≥a.
[0085] Specifically, a tapered aperture structure is adopted, that is, the entrance (the first aperture) of the straightening hole is larger than the exit (the second aperture), forming a structure similar to a flared opening or a conical channel. The larger aperture at the entrance facilitates the smooth entry of the gold wire 40 into the straightening hole, preventing the wire from bending or jamming due to sudden entry into a narrow aperture. After the gold wire 40 enters, the part with a larger aperture can play a role in preliminary correction, reducing the sudden change in stress when the gold wire 40 first enters the straightening hole. A smaller aperture is used at the exit of the straightening hole to ensure that the gold wire 40 undergoes final precise straightening when leaving the straightening hole, improving the straightness. Through the tapered structure, the gold wire 40 is gradually subjected to a uniform extrusion force during movement, rather than suddenly being subjected to a strong deformation force, avoiding damage to the surface of the gold wire 40.
[0086] Furthermore, the length of the straightening hole is greater than or equal to the length of the single displacement of the earpin to ensure that the gold wire 40 is always in a straightened state during movement: If b < a, the gold wire 40 may partially leave the straightening hole during one movement, resulting in discontinuous straightening effect and affecting the final straightness. If b ≥ a, it is ensured that during each movement, the stress-bearing area of the gold wire 40 is always inside the straightening hole, enabling continuous straightening and maintaining a stable effect. And the longer straightening hole provides a larger support surface, avoiding elastic recovery or vibration of the gold wire 40 due to short-term stress, and improving the straightening accuracy.
[0087] In a specific embodiment, the straightening mechanism 10 further includes a second straightening part 14 spaced apart from the first straightening part 11. The second straightening part 14 is provided with a second straightening hole 141, and the central axes of the first straightening hole 13 and the second straightening hole 141 are on the same straight line;
[0088] The first straightening part 11 and the second straightening part 14 are arranged in parallel along the moving direction of the gold wire 40, and the minimum aperture of the first straightening hole 13 is equal to the maximum aperture of the second straightening hole 141.
[0089] Specifically, by setting multiple straightening parts, each straightening part gradually adjusts the bending degree of the gold wire 40, allowing the gold wire 40 to gradually return to a straight state instead of being forcibly straightened at one time. This can effectively reduce stress concentration during the straightening process and avoid material failure due to sudden deformation. During the straightening process of the gold wire 40, the material will experience a certain degree of springback due to elastic deformation. Through multi-stage gradual straightening, each stage of the straightening part will further straighten the gold wire 40 and allow it to gradually release internal stress, ensuring a stable final straightening effect without deformation springback.
[0090] Furthermore, the central axis of the first straightening hole 13 and the second straightening hole 141 are located on the same straight line to ensure that the gold wire 40 can enter the second straightening hole 141 naturally and smoothly after passing through the first straightening hole 13, avoiding bending or jamming due to misalignment of the two. The gold wire 40 is always moved along a fixed straight line during the straightening process to avoid reducing the straightening accuracy due to offset. The minimum aperture of the first straightening hole 13 is equal to the maximum aperture of the second straightening hole 141 to ensure a smooth transition of the gold wire 40 from the first straightening hole 13 to the second straightening hole 141, avoiding deformation fluctuations caused by sudden changes in aperture.
[0091] In a specific embodiment, the processing device further includes a stabilizing mechanism 30 disposed between the propulsion mechanism and the straightening mechanism 10;
[0092] The stabilizing mechanism 30 is provided with a fixing hole, the central axis of which is on the same straight line as the central axis of the first straightening hole 13 , and the inner wall of the fixing hole is close to the gold wire 40 for stabilizing the gold wire 40 passing through the straightening mechanism 10 .
[0093] Specifically, the fixing hole serves as a physical limiting structure to guide the gold wire 40 to pass through and limit its degree of freedom so that it always enters the straightening mechanism 10 along a predetermined path. Prevent the gold wire 40 from swinging, shaking or deforming during the advancement process. Provide additional support to prevent the gold wire 40 from deviating from the trajectory due to external factors (such as airflow, mechanical vibration, etc.) during the advancement process. The central axis of the fixing hole and the central axis of the first straightening hole 13 are located on the same straight line to ensure that the gold wire 40 is precisely aligned with the straightening hole when entering the straightening mechanism 10, avoiding uneven straightening due to offset.
[0094] The embodiment of the present application provides a batch processing technology of gold ear needles with anti-slip grooves, which is applied to the batch processing equipment 100 of gold ear needles as described above. The batch processing technology of gold ear needles also includes the following steps:
[0095] The gold wire 40 passes through the guide mechanism and enters the straightening mechanism 10, and the straightening mechanism 10 rotates to straighten the gold wire 40;
[0096] The straightening mechanism 10 rotates to drive the oil dripping mechanism 20 to drip lubricating oil onto the gold wire 40, so as to reduce the friction force when the straightening mechanism 10 straightens the gold wire 40;
[0097] The pushing mechanism pushes the straightened gold wire 40 to move to the cutting mechanism for cutting to obtain a finished ear needle.
[0098] Specifically, the guide mechanism is used to perform preliminary linear positioning of the gold wire 40, ensure that it smoothly enters the straightening mechanism 10, limit the degree of freedom of the gold wire 40, and prevent the gold wire 40 from swinging or misaligned during transportation. The straightening mechanism 10 straightens the gold wire 40 by rotation, and uses rotational straightening to reduce the residual stress inside the gold wire 40 so that it achieves an ideal straightness. Rotational straightening can provide a more uniform and continuous straightening force, reduce local stress concentration, and improve straightening accuracy. During the rotation process, the gold wire 40 is subjected to a more uniform force, which can effectively reduce minor bends and improve the straightness of the finished ear needle compared to the static straightening method.
[0099] Furthermore, the oil dripping mechanism 20 cooperates with the straightening mechanism 10 to quantitatively drip lubricating oil during the straightening process, thereby reducing the friction between the gold wire 40 and the straightening mechanism 10, improving the straightening efficiency and reducing equipment loss. During the straightening process, there is friction between the gold wire 40 and the straightening hole, and the lubricating oil can reduce the friction coefficient and reduce damage to the surface of the gold wire 40. The gold wire 40 can pass more smoothly in the straightening mechanism 10, making the straightening effect more uniform and improving the straightness of the finished ear needle. The propulsion mechanism accurately controls the feed amount of the gold wire 40 to ensure that the length of each cut meets the design specifications of the ear needle. Ensure that the length of the ear needle is consistent and improve product consistency.
[0100] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
