Description

Technical Field

[0001] The present application relates to the field of gold processing, and in particular to a gold jewelry tubular structure processing device. Background Art

[0002] In the fine manufacturing process of the tubular structure of gold jewelry, local warping of the gold tube has become a difficult problem that needs to be solved urgently. The core of this problem lies in the complex mechanical effects and subsequent effects that the gold tube is subjected to during the continuous processing of the bending equipment and the pressing equipment. Specifically, the gold tube is gradually formed into a semi-finished gold tube through the rolling of the concave and convex rolling wheels in the bending equipment. During this process, complex stress distribution will be generated inside the gold tube, especially at the edges and corners. Due to the stress concentration effect, the stress values ​​in these parts are much higher than those in other parts. When these stresses exceed the yield strength of the gold tube, the gold tube will undergo plastic deformation, resulting in a deviation between the bent shape and the expected design, thereby forming local warping on the semi-finished gold tube. Next, in the pressing equipment, these semi-finished gold tubes with local warping need to be further processed into the required tubular structure. However, the warped gold tubes often cannot be correctly aligned with the pressing position during the pressing process, resulting in defects such as indentation or irregular shape in the finished gold tube after pressing. Especially in high-speed production processes, since the stress changes experienced by the gold tube during bending and pressing are more drastic, local warping is more likely to occur, seriously affecting the quality and precision of the finished product.

[0003] In order to correct the local warping problem of gold tubes caused by bending equipment during the production process, existing gold processing equipment has adopted the strategy of adding a correction plate between the bending equipment and the pressing equipment. However, this seemingly reasonable solution has encountered multiple challenges in actual operation.

[0004] First of all, the high thermal conductivity of gold has become a major obstacle in the correction process. When the correction plate contacts the semi-finished gold tube, due to the high thermal conductivity of gold, the heat will be quickly transferred from the correction plate to the gold tube. If the contact area during the correction process is large, the local overheating of the gold tube will affect its mechanical properties and processing quality. For example, in actual situations, when an overheated soft semi-finished gold tube is pressed and corrected by the correction plate, it may cause the semi-finished gold tube to sag in the correction direction and undergo plastic deformation, thereby producing scrap. In addition, this heat load may not only cause changes in the properties of the gold tube material, but may also cause cracks in subsequent processing, thereby reducing the overall quality of the product.

[0005] Secondly, the soft nature of gold is also a problem in the correction process. Since the surface hardness of gold is relatively low, the friction between the correction plate and the gold tube will cause wear on the surface of the gold tube. This wear not only reduces the surface finish and aesthetics of the gold tube, but may also affect its subsequent processing and performance, such as uneven mass distribution. Especially in the high-speed production process, the increase in the correction frequency further aggravates the wear problem of the gold tube, which greatly reduces the correction effect.

[0006] In addition, differences in equipment parameters and process requirements for different processing levels also lead to poor correction results. In the existing production process of gold jewelry tubular structures, semi-finished gold tubes of different levels often have different warping degrees and material properties. However, existing correction equipment often uses unified correction parameters and process requirements, and cannot accurately correct semi-finished gold tubes of different levels. This one-size-fits-all approach not only fails to effectively correct the warping problem, but may also cause new quality problems due to over-correction or under-correction.

[0007] In summary, the existing correction methods have encountered multiple challenges in practical applications, such as local overheating caused by the high thermal conductivity of gold, excessive wear caused by its soft properties, and poor correction results caused by differences in equipment parameters and process requirements at different processing levels. In order to solve these problems, it is necessary to develop more advanced and flexible correction technologies and equipment to meet the correction needs of semi-finished gold tubes of different levels, while reducing the impact of heat load and friction wear on the quality of gold tubes. Summary of the invention

[0021] One end of the elastic member is pressed against the pushing member, and the other end is pressed against the base, so that when the gold tube presses the correcting part, the elastic member drives the pushing member to press the correcting part to provide correcting stress.

[0022] In at least one embodiment of the present application, the thickness of the connecting portion is defined as M, and the thickness of the correcting portion is defined as N;

[0023] The thickness M of the connecting portion and the thickness N of the correcting portion satisfy the following relationship:

[0024] M=1.3N~1.33N.

[0025] In at least one embodiment of the present application, the correction portion and the connection portion intersect at a turning point, the intersection point of the arc surface and the plane on the first correction surface when the gold tube squeezes the correction portion is defined as a transition point, and the inner side surface of the connection portion away from the first bonding surface is defined as a first surface;

[0039] The above-mentioned gold jewelry tubular structure processing equipment proposes a new processing equipment by targeting the problem that the gold tube is prone to edge bending during the heating process when processing the gold jewelry tubular structure in the prior art, resulting in low processing accuracy and unstable product quality. The structural characteristics of the equipment and the positional relationship and connection relationship between them jointly bring significant beneficial effects and effectively solve the problems existing in the background technology. First, from the perspective of structural characteristics, the present application designs a first bending mechanism and a second bending mechanism, which are arranged in sequence along the same direction to ensure that the gold tube can pass continuously and smoothly and form a preliminary and further bending state respectively. This continuous bending design not only reduces the stress concentration and warping degree caused by a single bending, but also improves the overall processing accuracy. Secondly, the setting of the first corrector and its positional relationship with the first bending mechanism and the second bending mechanism further enhance the correction ability of the equipment. The first corrector uses an elastic rod to abut the lowest point of the central axis of the preliminary bent gold tube, presses the gold tube into the track, and effectively reduces the warping. This design not only corrects the gold tube after the preliminary bending in a timely manner, but also provides a more stable foundation for subsequent processing. Furthermore, the second corrector combines a soft correction structure with a hard correction structure, and performs preliminary correction on the gold tube in the second bent state through the elastic contact between the elastic member and the correction frame. Subsequently, the gold tube slides over the welding edge and contacts the hard correction structure to be further corrected to a straight state. This correction method combining soft and hard not only protects the surface of the gold tube from damage, but also improves the correction accuracy and stability. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0077] Please refer to Figure 1 - Fig.31 In one embodiment of the present application, a gold jewelry tubular structure processing device 100 is provided.

[0078] Specifically, the tubular processing equipment of the gold jewelry includes: a first bending mechanism 1 and a second bending mechanism 2 and a first corrector 3 and a second corrector 4 arranged in sequence. The first corrector 3 is arranged between the first bending mechanism 1 and the second bending mechanism 2, and the first corrector 3 abuts against the lowest point of the central axis of the gold tube 35, and is used to press the gold tube 35 into the track 31 and reduce the warping of the gold tube 35. In a specific embodiment, the first corrector 3 is provided with an elastic rod 34 abutting against the gold tube 35, and the elastic rod 34 abuts against the lowest point of the central axis in the first bending state, and is used to press the gold sheet in the first bending state into the track 31 and press the gold tube 35 by elasticity to reduce the warping of the gold tube 35.

[0079] Furthermore, the second corrector 4 includes a soft corrective structure 5 and a hard corrective structure 6, the soft corrective structure 5 has a first bonding surface 7 and a first corrective surface 8, the hard corrective structure 6 has a second bonding surface 9 and a second corrective surface 10, when the first bonding surface 7 is bonded to the second bonding surface 9, the first corrective surface 8 is connected to the second corrective surface 10 and is located in the same plane, so that the gold tube 35 can be evenly pressurized when sliding over, and the first corrective surface 8 and the second corrective surface 10 are parallel to the bottom surface of the track 31, so that the soft corrective structure 5 cooperates with the hard corrective structure 6 to correct the gold tube 35 and finally make it fit the bottom surface of the track 31.

[0080] It should be noted that when the gold tube 35 fits the bottom surface of the track 31, the gold tube 35 is no longer warped and has reached a straight state, which enables the gold tube 35 to be in the correct pressing position in the subsequent pressing step, thereby avoiding defects such as indentation or irregular shape of the finished gold tube 35. Among them, when the gold tube 35 passes through the soft correction structure 5 and the hard correction structure 6 in turn through the track 31, the gold tube 35 can squeeze the soft correction structure 5 to deform it, and cause the first correction surface 8 and the second correction surface 10 to warp and form an arc surface. When observed along the sliding direction perpendicular to the gold tube 35, the arc surface is formed by the lower end surface of the soft correction structure 5 connecting with the lower end surface of the hard correction structure 6 parallel to the bottom surface of the track 31, which is used to gradually reduce the stress on the gold tube 35 through the first correction surface 8 and the second correction surface 10. Among them, the arc surface is used for flexible correction. Since gold is a soft metal, it is not easy to be deformed when subjected to relatively large Large concentrated stress is prone to wrinkle bending or deformation. Therefore, unlike traditional hard correction plates, using a curved surface as a correction structure can significantly reduce the local concentrated stress on the gold tube 35. When the gold tube 35 is subjected to external force, if its surface is sharp or has mutations, stress concentration will occur at these positions, and the curved surface design can make the stress distribution more uniform, because the curved surface has no sharp edges, and the stress streamlines can bypass the curved surface more smoothly, instead of changing sharply at a certain point or in a small area. In this way, the stress will not be overly concentrated at a certain position, but will be dispersed over the entire curved surface, thereby reducing the degree of stress concentration.

[0081] It should be particularly noted that the first gluing surface 7 and the second gluing surface 9 are mutually glued together, thereby reducing the risk of the soft corrective structure 5 being separated from the hard corrective structure 6 during the correction process. This is because the gluing connection between the surfaces is more stable. When the gold tube 35 abuts against the soft corrective structure 5, the soft corrective structure 5 drives the first corrective surface 8 to warp upward around the point on the contact end between the hard corrective structure 6 and the soft corrective structure 5, so that the first corrective surface 8 connects with the second corrective surface 10 to form the arc surface. In the process of the gold tube 35 continuously extending, the contact end will be subjected to gradually increasing extrusion stress, and the gluing between the surfaces can make the connection between the soft corrective structure 5 and the hard corrective structure 6 more stable. This is because the surface gluing can distribute the local stress on the gluing surface to reduce the local stress. Therefore, the soft corrective structure 5 can also provide a more uniform corrective force during the correction process.

[0082] In a specific embodiment, if the soft corrective structure 5 is connected to the hard corrective structure 6 in a point-to-point manner via a hinge, in the process of the soft corrective structure 5 warping and forming an arc surface, due to the characteristics of the point connection, the hinge is subjected to a large concentrated stress at the connection point, which leads to the risk of the hinge breaking, and the soft corrective structure 5 cannot obtain effective support force at the connection point, thereby causing the soft corrective structure 5 to flex or extend excessively or insufficiently, thereby failing to achieve the original correction effect.

[0083] Specifically, the soft correction structure 5 includes an integral correction part 11 and a connection part 12. The first bonding surface 7 is provided on the connection part 12 and is bonded to the second bonding surface 9. The first correction surface 8 is provided on the correction part 11 and is parallel to the bottom surface of the track 31.

[0084] Further, the thickness of the connecting portion 12 is defined as M, and the thickness of the correcting portion 11 is defined as N. The thickness M of the connecting portion 12 and the thickness N of the correcting portion 11 satisfy the following relationship:

[0085] M=1.25N~1.33N.

[0086] Among them, the connecting part 12, as a supporting structure, needs to have sufficient thickness to ensure its stability. At the same time, the connecting part 12 must also be able to more effectively withstand the pressure from the correcting part 11 to ensure that the device maintains stability during long-term use, and the appropriate ratio helps to optimize the stress distribution. When the thickness ratio of the connecting part 12 to the correcting part 11 is reasonable, the gold tube 35 can be subjected to a more uniform and stable corrective force when squeezed, thereby reducing stress concentration. The following is the result of compiling some experimental data in tabular form:

[0087]

[0088] The ratio of the thickness M of the connecting part 12 to the thickness N of the correcting part 11 has a significant impact on the performance of the gold jewelry tubular structure processing equipment. In the experiment, the ratio of 1.30 showed the best comprehensive performance, including good support effect, uniform stress distribution and high gold tube 35 processing quality.

[0089] Furthermore, the correction part 11 and the connection part 12 are defined to intersect at a turning point X, the intersection point of the arc surface and the plane on the first correction surface 8 when the gold tube 35 squeezes the correction part 11 is defined as a transition point Y, and the inner side surface of the connection part 12 away from the first bonding surface 7 is defined as a first surface 20;

[0090] When the gold tube 35 squeezes the correction portion 11 , the turning point X is a rotation fulcrum, and the transition point Y is located between the first surface 20 and the first gluing surface 7 .

[0091] Furthermore, the vertical distance between the transition point Y and the first surface 20 is Q, wherein the vertical distance Q satisfies the following relationship:

[0092] Q=0.3N~0.33N.

[0093] Among them, selecting a suitable ratio of Q to N can optimize stress distribution and improve processing quality and equipment life. When the vertical distance Q is a reasonable multiple of the thickness N of the correction part 11, it can ensure that the contact area between the correction part 11 and the gold tube 35 is moderate, and neither excessive pressure will be caused by a small contact area, nor unnecessary friction resistance will be increased due to a large contact area. At the same time, this ratio also helps to reduce stress concentration and reduce the risk of damage to the gold tube 35 during processing.

[0094] This is because the position of the turning point X is associated with the thickness of the connecting portion 12 and the correcting portion 11. When the connecting portion 12 and the correcting portion 11 are both thin, in order to provide sufficient corrective force, the position of the turning point X will be close to the end of the hard corrective structure 6, which makes the contact area between the gold tube 35 and the soft corrective structure 5 too large and increases the friction resistance. In another case, when the connecting portion 12 and the correcting portion 11 are both thicker, since the corrective force is much greater than the extrusion stress provided by the gold tube 35 extruding the soft corrective structure 5, the position of the turning point X will be located at the end of the soft corrective structure 5 away from the hard corrective structure 6, which causes the gold tube 35 to be subjected to a larger corrective stress during correction. Since the metal itself is relatively soft, and its warped edge is subjected to excessive concentrated stress, the edge will be concave and thus produce scrap. It can be seen that a suitable ratio between Q and N helps reduce the risk of damage to the gold tube 35 during processing.

[0095] The following is the result of writing some experimental data in tabular form:

[0096]

[0097] When the vertical distance Q and the thickness N of the correction part 11 satisfy the proportional relationship Q=0.3~0.33×N, the processing effect of the equipment is the best. This proportional relationship can optimize the stress distribution and ensure that the contact area between the correction part 11 and the gold tube 35 is moderate, thereby improving the processing accuracy and efficiency, and reducing the risk of damage to the gold tube 35.

[0098] It should be noted that the thickness ratio design of the connecting part 12 and the correcting part 11 and the setting of the vertical distance Q are interrelated. A reasonable thickness of the connecting part 12 can provide sufficient supporting force, and a reasonable setting of the vertical distance Q can ensure that the contact area between the correcting part 11 and the gold tube 35 is moderate. When the thickness of the connecting part 12 is too large, although it can provide stronger supporting force, it will also increase the weight and cost of the equipment. At this time, by reasonably setting the vertical distance Q, the weight of the equipment can be reduced and the cost can be reduced while ensuring the processing accuracy. Similarly, when the thickness of the connecting part 12 is too small, although it can reduce the weight of the equipment and reduce the cost, the supporting force may be reduced. At this time, by increasing the vertical distance Q, the lack of supporting force can be compensated to a certain extent to ensure the stability of the equipment.

[0099] Specifically, the correction part 11 is arranged on the side of the connection part 12 away from the hard correction structure 6, and the first correction surface 8 and the second correction surface 10 are located in the same plane. The soft correction structure 5 also includes an elastic component 13. The correction part 11 and the connection part 12 are enclosed to form a receiving cavity. The elastic component 13 is arranged in the receiving cavity and is used to provide correction stress when the gold tube 35 squeezes the correction part 11. In a specific embodiment, the gold tube 35 squeezes the correction part 11 to warp upward and squeezes the elastic component 13 to undergo elastic deformation. The elastic component 13 can restore the deformation in a direction away from the warping direction and provide the gold tube 35 with a correction force in a direction away from the warping direction of the gold tube 35.

[0100] Furthermore, the elastic component 13 includes a base 14, a pushing member 15 and an elastic member 16. The base 14 is fixed in the accommodating cavity, and a sliding hole 17 is provided in the base 14. One end of the pushing member 15 is arranged in the accommodating cavity, and the other end extends into and is located in the correcting portion 11 through the sliding hole 17. One end of the elastic member 16 abuts against the pushing member 15, and the other end abuts against the base 14, so that when the gold tube 35 squeezes the correcting portion 11, the elastic member 16 drives the pushing member 15 to squeeze the correcting portion 11 to provide a corrective stress, and when the elastic component 13 is compressed, the correcting portion 11 warps upward and drives the base 14 to slide along the length direction of the pushing member 15 through the sliding hole 17 to push the elastic member 16 and provide a corrective force.

[0101] In a specific embodiment, the elastic member 16 may be a spring.

[0102] Specifically, the correction part 11 includes a stress part and a buffer part 32. The stress part is provided on the connection part 12, and one end of the elastic component 13 is located in the stress part. The buffer part 32 extends from the stress part to one end away from the hard correction structure. In a specific example, the buffer part 32 is an arc-shaped structure. In a rapid production environment, if the gold tube 35 directly abuts the correction structure, it is easy to be subjected to a large concentrated stress at the edge, resulting in edge warping or even bending. When the gold tube 35 abuts the arc-shaped structure, the arc-shaped edge can reduce the stress concentration, so that the gold tube 35 is not easy to be hard-abutted when entering the correction part 11, thereby avoiding warping or bending problems.

[0103] It should be noted that the buffer portion 32 mentioned above includes but is not limited to an arc-shaped structure, and may also be a circular or wavy structure, and its main function is to reduce the edge stress on the gold tube 35 when entering the correction portion 11.

[0104] Specifically, the gold jewelry tubular structure processing equipment 100 further includes a pressing mechanism 21, which is arranged behind the second corrector 4. The pressing mechanism 21 includes a pressing seat 22 and a pressing piece 23. The pressing seat 22 is provided with a placement groove 24 for placing the gold tube 35. After the gold tube 35 is corrected by the second corrector 4, part of it is placed in the placement groove 24. The pressing piece 23 is located on the pressing seat 22 and is used to press the gold tube 35.

[0105] Furthermore, the pressing part 23 includes a driving part 25 and a pressing part 26 disposed on the driving part 25. The pressing part 26 is provided with a pressing arc surface 27 for abutting and pressing the gold tube 35, and the pressing arc surface 27 has a first contact point 28 and a second contact point 29 abutting against the gold tube 35, and a fault-tolerant groove 30 is formed between the first contact point 28 and the second contact point 29, which is concave relative to the gold tube 35, and the fault-tolerant groove 30 is used to prevent the gold tube 35 from folding during the pressing process. Among them, in the pressing arc surface 27 between the first contact point 28 and the second contact point 29, the gold tube 35 abuts the first contact point 28 and the second contact point 29 in sequence to form the gold tube 35 in a closed state.

[0106] It should be specifically explained that the pressing portion 26 has a maximum pressing radius, which is the maximum radius of the gold tube 35 allowed to pass through, and the process of the gold tube 35 being converted into a closed state is as follows: the bent edge of the gold tube 35 first abuts the first contact point 28 and reduces its bending radius and extends along the second contact point 29. It should be noted that the bending radius is the bending degree formed by the bending mechanism when bending the gold tube 35. When observed along the sliding direction of the gold tube 35, the bending degree can be recorded as the bending radius of the gold tube 35, and the bending radius is numerically the same as the pressing radius. Equivalently, then, the second contact point 29 abuts against the edge of the gold tube 35 and presses the gold tube 35 to form a closed state, wherein, when the gold tube 35 entering the pressing portion 26 is warped, its warped edge will abut against the pressing arc surface 27, causing the gold tube 35 to squeeze the pressing arc surface 27 and fold over, and the setting of the fault-tolerant groove 30 avoids the above situation from occurring, because the concave design of the fault-tolerant groove 30 allows the warped gold tube 35 to pass through, and then abuts against the first contact point 28 and the second contact point 29 in turn to form the gold tube 35 in a closed state.

[0107] Implementing the gold jewelry tubular structure processing equipment 100 of this embodiment will have at least the following beneficial effects:

[0108] 1. In a fast production environment, the gold tube 35 is not easy to produce concave waste;

[0109] 2. The second corrector 4 can effectively reduce the local concentrated stress on the gold tube 35 during the correction process of the gold tube 35;

[0110] 3. In a fast production environment, the pressing mechanism 21 can effectively press the alloy tube 35 to form a closed state and prevent the non-standard gold tube 35 from folding.

[0111] Thereby, the gold jewelry tubular structure processing equipment 100 effectively solves the problems of the gold tube 35 being easy to bend, low processing precision, unstable product quality, and reduced hardness of the gold tube 35 due to heat problems in rapid production scenarios, thereby significantly improving the processing quality and efficiency of the gold jewelry tubular structure.

[0112] The above-mentioned embodiments only express several embodiments of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application.
