Description

Technical Field

[0001] The present invention relates to the technical field of metal spring production, and particularly relates to an integrated forming mechanism for the production of millimeter-scale springs. Background Art

[0002] During the manufacturing process of springs, due to differences in the diameters of the materials to be processed, it is necessary to adjust the equipment structure during the material transportation and straightening stages to adapt to metal wire rods of different specifications. Aiming at the problem that the traditional double-roller structure cannot adapt to the changes in different wire diameters and spring radii, Patent CN202410766256.7 proposed a spring machine with an adjustment function. By optimizing the material traction mechanism and adopting an adjustable mounting frame and an inclination angle adjustment component, the function of adjusting the spring forming radius according to different production requirements was realized. However, in practical applications, especially when producing millimeter-scale springs, the device still faces the following problems:

[0003] Firstly, the device mainly adjusts the distance between the two rollers to meet the production requirements of springs with different radii. However, since the groove structure on the roller surface is fixed and cannot be automatically adjusted with the change of the spring radius. For springs with a larger diameter, because of their larger diameter, the matching accuracy requirements for the roller grooves are lower, and the fitting error can be accepted within a certain range. Therefore, only by adjusting the roller spacing can the processing requirements be met. However, this defect is particularly prominent in the production of millimeter-scale springs. At this time, the spring diameter is extremely small, and the requirements for the fit between the roller and the material are extremely high. If only relying on adjusting the roller spacing without being able to synchronously adjust the groove size, it is very easy to cause poor fit between the roller and the spring outer diameter, thereby affecting the feeding accuracy and forming stability.

[0004] Secondly, the existing double-roller structure usually adopts a single-wheel drive method to drive the material to feed. For springs with a larger diameter, the metal wire rods used are thicker and harder, and the feeding process is relatively stable. Therefore, this drive method can basically meet the usage requirements. However, due to structural limitations, certain sliding errors may still occur, affecting the consistency of the spring length. In the production of micro-springs, this problem is further amplified. The thin and low-rigidity wire rods put forward higher requirements for the synchronization and control accuracy of the feeding system. The single-wheel drive is significantly insufficient in torque transmission, synchronization, and response sensitivity, and it is easy to cause problems such as material slipping, uneven feeding, or deviation, thereby affecting the quality and dimensional consistency of the springs. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an integrated forming mechanism for the production of millimeter-scale springs to solve the problems existing in the above-mentioned background art.

[0006] To solve the above technical problems, the technical solution of the present invention is an integrated forming mechanism for producing millimeter-scale springs, including a feeding component and a forming component. The feeding component includes feeding wheels arranged vertically adjacent to each other. The feeding wheel includes a male body and a female body. Both the male body and the female body have a taper. The small end faces of the male body and the female body are arranged adjacent to each other. The male body and the female body are slidably connected and embedded in each other, so that an annular groove is formed on the side surface of the feeding wheel. By controlling the connection degree of the male body and the female body, the adjustment of the depth and width of the groove is realized. The feeding wheels are divided into a first feeding wheel and a second feeding wheel. By controlling the vertical distance between the first feeding wheel and the second feeding wheel, the adjustment of the spacing of the feeding wheels is realized. By adjusting the groove and / or the spacing of the feeding wheels, the feeding component can meet the production feeding of springs with different calibers.

[0007] Preferably, the male body and the female body are coaxially arranged. Both the male body and the female body are provided with taper structure members arranged in an annular array. There is a gap between adjacent taper structure members. The gap is used as a sliding groove on either the male body or the female body. The sliding groove of the male body is adapted to the taper structure member of the female body, and the taper structure member of the male body is adapted to the sliding groove of the female body. The axial end face width of only one of the taper structure members on the male body and the female body remains unchanged all the time to ensure that the sliding control between the male body and the female body can be carried out.

[0008] Furthermore, the male body and the female body are respectively provided with a slide bar and a slide hole. The slide bar and the slide hole are both located on the axis of the male body and the female body. Mounting plates are provided on the large end faces of the male body and the female body. The mounting plates are fixedly connected to the taper structure members. The feeding component is equipped with a fixing plate and a control plate. The mounting plates are rotatably arranged on the fixing plate and the control plate. By controlling the distance between the fixing plate and the control plate, the sliding adjustment of the male body and the female body is realized.

[0009] Preferably, the groove is a V-shaped groove. When the taper ratios of both the male body and the female body are two, the grooves on the first feeding wheel and the second feeding wheel form a square in the feeding direction. Only by controlling the connection degree of the male body and the female body, the feeding component can meet the production feeding of springs with different calibers.

[0010] Furthermore, the feeding component is equipped with a driving component. The driving component is arranged on one side of the feeding component where the fixing plate is located. The driving component includes a first gear and a second gear respectively arranged on the first feeding wheel and the second feeding wheel. The double-wheel synchronous driving of the feeding component is realized by the transmission of the first gear and the second gear.

[0011] Further, the driving component includes a first connecting rod and a second connecting rod. One end of the first connecting rod and one end of the second connecting rod are rotatably connected to each other. The other ends of the first connecting rod and the second connecting rod are respectively swingably arranged on the first feeding wheel and the second feeding wheel. A third gear is arranged at the rotatable connection end of the first connecting rod and the second connecting rod. A fourth gear is arranged on the second connecting rod. The third gear meshes with the first gear, the fourth gear meshes with the third gear, and the fourth gear meshes with the first gear. The specification parameters of the first gear, the second gear, and the third gear are the same. Through the transmission of the first gear, the second gear, the third gear, and the fourth gear, the double-wheel synchronous drive of the feeding component is realized. When the distance between the first feeding wheel and the second feeding wheel is adjusted, the third gear and the fourth gear are driven by the first connecting rod and the second connecting rod to move, so that the driving component can realize the double-wheel synchronous drive of the feeding component with different distances.

[0012] Further, the feeding components are respectively a first feeding component and a second feeding component arranged horizontally adjacent to each other. Through the synchronous feeding of the first feeding component and the second feeding component, the straightness of the feeding during the conveying process is ensured, thereby effectively avoiding adverse effects on the subsequent production and forming of the spring due to material offset or deformation. The first feeding component and the second feeding component are both arranged on the same fixed plate and the control plate to ensure the synchronous control of the first feeding component and the second feeding component.

[0013] Further, a fifth gear and a sixth gear are arranged on the fixed plate. The fifth gear meshes with the sixth gear. The sixth gear meshes with the first gear or the second gear. The fifth gear is connected to the second feeding component. Under the action of the fifth gear and the sixth gear, the driving component realizes the synchronous drive of the first feeding component and the second feeding component.

[0014] Preferably, it includes a straightening component, and the straightening component uses the feeding wheel to straighten the material.

[0015] The technical effects of the present invention are mainly reflected in the following aspects:

[0016] The present invention arranges the first feeding component and the second feeding component horizontally adjacent to each other and realizes synchronous driving by a unified control system, ensuring that the wire always maintains a straight-line motion state before entering the forming component; not only improving the straightness during the feeding process, but also reducing the influence on subsequent spring forming caused by material deviation or deformation. In addition, the design of the fifth gear and the sixth gear enables mechanical rigid synchronization between the two feeding components, and even when the distance changes, a stable transmission relationship can be maintained, further enhancing the reliability and stability of the system;

[0017] Introducing a multi-stage gear transmission system including the first gear, the second gear, the third gear and the fourth gear realizes the high-precision synchronous rotation of the first feeding wheel and the second feeding wheel. It can not only ensure the synchronous rotation of the two wheels, but also adapt to the first feeding wheel and the second feeding wheel with different distances. Specifically, when the distance between the first feeding wheel and the second feeding wheel changes (for example, to adapt to the production of springs with different diameters), the first connecting rod and the second connecting rod will drive the third gear and the fourth gear to move accordingly. Since the relative positions of these gears are connected by mechanical linkage, even when the distance changes, good meshing states can still be maintained between the gears, thus maintaining stable synchronous driving performance. This design greatly increases the flexibility of the equipment, enabling it to easily meet the production requirements of various specifications of springs without additional adjustment or component replacement of the transmission system.

[0018] By controlling the connection degree between the male body and the female body to dynamically adjust the groove size, high-precision clamping and stable feeding of wires with different diameters are realized; the groove formed when the male body and the female body slide relative to each other is utilized, and the width and depth of the groove can be accurately changed according to actual needs to ensure the best clamping force. It not only improves the straightness and stability during the feeding process, avoiding wire offset or slipping caused by unstable clamping, and is especially suitable for thin-diameter wires used in the production of millimeter-level springs.

[0026] The following further details the specific embodiments of the present invention in conjunction with the accompanying drawings, so that the technical solutions of the present invention are easier to understand and master. In the embodiments, it should be understood that the orientation or positional relationships indicated by terms such as "middle", "upper", "lower", "top", "right side", "left end", "above", "back", "middle part", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention. Additionally, in this specific embodiment, if the connection or fixing method between components is not specifically stated, the connection or fixing method can be bolt fixing, pin fixing, or pin shaft connection, etc., which are commonly used in the prior art. Therefore, it will not be elaborated in this embodiment.

[0027] An integrated forming mechanism for the production of millimeter-scale springs provided by the present invention is mainly applied to the integrated forming production of springs, especially the production of millimeter-scale springs, but it should not be limited to this, and can also be used in other identical or similar production processes.

[0028] Embodiment 1

[0029] See Figure 1 、 Figure 2To solve the problems of low feeding accuracy and poor forming stability in spring production by existing spring machines, this embodiment discloses an integrated forming mechanism for millimeter-level spring production, which is applicable to wire materials with various cross-sectional shapes (such as cylindrical, elliptical, and rectangular, etc.). It includes a feeding component 1 and a forming component 2. The feeding component 1 includes feeding wheels 11 arranged vertically adjacent to each other. The feeding wheels 11 are divided into a first feeding wheel 13 and a second feeding wheel 14. Each feeding wheel 11 includes a male body 111 and a female body 112. Both the male body 111 and the female body 112 have a taper. The small end faces of the male body 111 and the female body 112 are arranged adjacent to each other. The male body 111 and the female body 112 are slidably connected and embedded with each other, so that an annular groove 12 is formed on the side surface of the feeding wheel 11. By controlling the connection degree of the male body 111 and the female body 112, the adjustment of the depth and width of the groove 12 is realized. It breaks through the limitation of the traditional fixed groove 12 structure, enabling the feeding wheel 11 to adaptively match spring wire materials with different diameters, especially suitable for the high-precision feeding requirements of millimeter-level micro springs. For example, when processing thin-diameter wire materials, by narrowing the width of the groove 12 and deepening the depth of the groove 12, the contact area between the roller and the wire material can be effectively increased, preventing slipping or offset caused by poor fitting. By controlling the vertical distance between the first feeding wheel 13 and the second feeding wheel 14, the adjustment of the spacing of the feeding wheels 11 is realized. By adjusting the groove 12 and / or the spacing of the feeding wheels 11, the feeding component 1 can meet the production feeding requirements for springs with different calibers. By adjusting the vertical distance between the first feeding wheel 13 and the second feeding wheel 14, the forming requirements of springs with different radii can be adapted. This adjustment function and the groove 12 size adjustment function work together to achieve the overall optimization of the feeding system. For example, when processing springs with a larger radius, appropriately widening the spacing of the feeding wheels 11 and cooperating with a shallower groove 12 can meet the requirements; while when processing micro helical compression springs, the spacing needs to be reduced and the shape of the groove 12 needs to be precisely adjusted to ensure the continuity and consistency of material transportation.

[0030] Regarding "the small end faces of the male body 111 and the female body 112", the male body 111 and the female body 112 can be a cone and a frustum of a cone. In this embodiment, the frustum of a cone is used. The explanations of the small end face and the subsequent large end face are as follows: In the frustum of a cone, there is a conical surface with an arc, and the two side end faces are the small end face and the large end face. The large end face and the small end face refer to the area.

[0031] See Figure 3 、 Figure 4 、 Figure 5, a deep structural optimization has been carried out on the basis of the original feeding component 1: the male body 111 and the female body 112 are coaxially arranged, and both the male body 111 and the female body 112 are provided with taper structure members 113 distributed in an annular array. There is a gap between adjacent taper structure members 113. On both the male body 111 or the female body 112, the gap is used as a sliding groove 114. The sliding groove 114 of the male body 111 is adapted to the taper structure member 113 of the female body 112, and the taper structure member 113 of the male body 111 is adapted to the sliding groove 114 of the female body 112; for example, when the taper structure member 113 on the male body 111 is inserted into the sliding groove 114 of the female body 112, the two form a nested structural relationship. This design makes the relative displacement between the male body 111 and the female body 112 have directivity and stability, avoiding poor contact or jamming caused by offset. There is only one taper structure member 113 on the male body 111 and the female body 112 whose axial end face width remains unchanged all the time to ensure that the male body 111 and the female body 112 can be slidably controlled; this specific structural member serves as a "reference guide", playing a positioning and limiting role during the sliding process, preventing structural instability caused by multi-point synchronous error, and thus ensuring the accuracy of the adjustment of the groove 12. By using the cooperation between the taper structure member 113 and the sliding groove 114 between the male body 111 and the female body 112, the dynamic adjustment of the size of the groove 12 is realized, significantly improving the fitting accuracy between the roller and the wire, and is particularly suitable for clamping wires with a small diameter.

[0032] See Figure 4 , Figure 5 , the male body 111 and the female body 112 are respectively provided with a sliding rod 115 and a sliding hole 116, and both the sliding rod 115 and the sliding hole 116 are located on the axis of the male body 111 and the female body 112; this not only enhances the coaxiality and rigidity of the connection between the two, but also provides physical support and motion guidance for subsequent adjustment actions. This axial sliding cooperation method enables the male body 111 and the female body 112 to achieve precise displacement under the drive of the control system, and then change the size of the formed annular groove 12. On the large end faces of both the male body 111 and the female body 112, there are mounting plates 117, and the mounting plates 117 and the taper structure members 113 are fixedly connected; an integrated or fastening connection method is adopted between the mounting plates 117 and the taper structure members 113 to ensure the stability and load-bearing capacity of the overall structure.

[0033] See Figure 2, the feeding component 1 is equipped with a fixing plate 15 and a control plate 16, and the mounting plates 117 are rotatably arranged on the fixing plate 15 and the control plate 16; by controlling the distance between the fixing plate 15 and the control plate 16, the sliding adjustment of the male body 111 and the female body 112 is realized. Through the displacement amount applied by the control plate 16, the embedding depth between the male body 111 and the female body 112 can be accurately controlled, thereby changing the width and depth of the annular groove 12. For example, when processing spring wire, the control system will automatically calculate the required groove 12 size and drive the control plate 16 to move through the servo motor, so that the embedding degree between the male body 111 and the female body 112 reaches the best matching state, thereby ensuring that the roller is closely attached to the wire and improving the feeding stability.

[0034] See Figure 6 , by optimizing the structural design of the driving component 3, not only the response speed and control accuracy of the feeding system are improved, but also the problems of sliding error and uneven feeding that are prone to occur in the processing of micro springs by traditional single-wheel drive are effectively solved. Specifically as follows:

[0035] The feeding component 1 is equipped with a driving component 3, and the driving component 3 is arranged on one side of the fixing plate 15 on the feeding component 1. The driving component 3 includes a first gear 31 and a second gear 32 respectively arranged on the shaft ends of the first feeding wheel 13 and the second feeding wheel 14; through the transmission of the first gear 31 and the second gear 32, the double-wheel synchronous drive of the feeding component 1 is realized.

[0036] The driving component 3 includes a first connecting rod 33 and a second connecting rod 34. One end of the first connecting rod 33 and one end of the second connecting rod 34 are rotatably connected to each other. The other ends of the first connecting rod 33 and the second connecting rod 34 are respectively swingably arranged on the first feeding wheel 13 and the second feeding wheel 14, forming a dynamically supported connecting rod structure; such that when the distance between the feeding wheels 11 changes, the connecting rod can adjust its angle accordingly to ensure the continuity and stability of the transmission path. A third gear 35 is provided at the rotatable connection end of the first connecting rod 33 and the second connecting rod 34. A fourth gear 36 is provided on the second connecting rod 34. The third gear 35 meshes with the first gear 31. The fourth gear 36 meshes with the third gear 35. The fourth gear 36 meshes with the first gear 31. The first gear 31, the second gear 32 and the third gear 35 have the same specification parameters to ensure the same transmission ratio, so as to achieve the completely synchronous rotation between the first feeding wheel 13 and the second feeding wheel 14. Through the transmission of the first gear 31, the second gear 32, the third gear 35 and the fourth gear 36, the double-wheel synchronous drive of the feeding component 1 is realized; when the distance between the first feeding wheel 13 and the second feeding wheel 14 is adjusted, the first connecting rod 33 and the second connecting rod 34 drive the third gear 35 and the fourth gear 36 to move, enabling the driving component 3 to realize the double-wheel synchronous drive of the feeding component 1 with different distances.

[0037] Through the linkage system composed of the first gear 31, the second gear 32, the third gear 35 and the fourth gear 36, the double-wheel synchronous drive of the first feeding wheel 13 and the second feeding wheel 14 is realized; at the same time, the multi-stage gear meshing design not only improves the transmission efficiency, but also significantly enhances the stability of torque transmission, especially suitable for the micro spring processing scenario that requires high-frequency start-stop or variable-speed operation. When the distance between the first feeding wheel 13 and the second feeding wheel 14 changes (for example, adjusted according to the spring radius), the first connecting rod 33 and the second connecting rod 34 will generate swing displacements as the feeding wheels 11 move, driving the synchronous adjustment of the positions of the third gear 35 and the fourth gear 36; ensuring that in different distance states, good meshing states can still be maintained between the gears, so as to maintain stable synchronous drive performance.

[0038] See Figure 6 , on the basis of the original single-segment feeding adjustment and double-wheel drive, a double-segment synchronous feeding structure in the horizontal direction is further introduced, that is, the first feeding component 37 and the second feeding component 38 are arranged horizontally adjacent to each other, and their coordinated operation is realized through a unified control system, improving the straightness and stability in the wire feeding process, and effectively avoiding the spring forming defects caused by material offset or deformation. The specific settings are as follows:

[0039] The feeding components 1 are respectively a first feeding component 37 and a second feeding component 38 which are arranged horizontally and adjacently. The synchronous feeding of the first feeding component 37 and the second feeding component 38 ensures the straightness of the feeding during the conveying process, thereby effectively avoiding the adverse effects on the subsequent production and forming of the spring due to material displacement or deformation. The first feeding component 37 is close to the raw material entrance and is responsible for the initial traction and rough adjustment. The second feeding component 38 is located behind it, receiving the wire material sent from the front section, and performing fine adjustment and stable output. The two-stage structure can perform secondary correction on the metal wire before it enters the forming component 2, ensuring that it is always on the ideal motion trajectory, thereby improving the subsequent spring forming quality. The first feeding component 37 and the second feeding component 38 are both arranged on the same fixed plate 15 and the control plate 16 to ensure the synchronous control of the first feeding component 37 and the second feeding component 38. Each feeding component 1 is composed of a pair of adjustable feeding wheels 11 (including a male body 111 and a female body 112), and is equipped with the aforementioned gear-connecting rod transmission system for realizing the adjustment of the roller groove 12 and the synchronous driving of the two wheels.

[0040] The fixing plate 15 is provided with a fifth gear 39 and a sixth gear 40, the fifth gear 39 and the sixth gear 40 are meshed, the sixth gear 40 is meshed with the first gear 31 or the second gear 32, and the fifth gear 39 is connected with the second feeding component 38; under the action of the fifth gear 39 and the sixth gear 40, the driving component 3 realizes synchronous driving of the first feeding component 37 and the second feeding component 38. The power source that originally only drives a single feeding component 1 is expanded to two feeding components 1, and mechanical rigidity synchronization is achieved through the gear meshing relationship, ensuring that the two are completely consistent in rotation speed, torque output and position change.

[0041] See also Figure 1 , including a straightening component 4. Straightening is an indispensable step in the spring production process. It is mainly used to eliminate the bending and twisting that may occur in the wire during transportation or storage, and ensure that the wire enters the subsequent processing link in a straight state. The straightening component 4 uses the feed wheel 11 to straighten the material. The feed wheel 11 is used to straighten the material, mainly by the rotation of the feed wheel 11 and the pressure it applies to the wire to achieve the straightening of the material.

[0042] Embodiment 2

[0043] This embodiment discloses an integrated molding mechanism for millimeter-level spring production. On the basis of the previous embodiment, the shape design of the groove 12 of the feed wheel 11 is further optimized, and adaptive clamping of spring wires of different calibers is achieved through a specific taper ratio.

[0044] Specifically, the groove 12 is a V-shaped groove, that is, its cross-section is in a "V" shape, and both sides are jointly formed by the conical surfaces of the male body 111 and the female body 112, which is used to clamp the metal wire and provide sufficient friction to achieve stable feeding.

[0045] When the taper ratios of both the male body 111 and the female body 112 are two (i.e., the taper angle is 1:2), it means that for every unit length of extension, the diameter changes by 0.5 units. The grooves 12 on the first feeding wheel 13 and the second feeding wheel 14 form a square in the feeding direction. This state is suitable for clamping the spring wire with a standard circular cross-section, which can effectively improve the clamping stability and reduce the risk of wire rolling and offset. By only controlling the connection degree of the male body 111 and the female body 112, the feeding component 1 can be made to meet the production feeding requirements for springs of different calibers. That is, the depth of the sliding embedding can dynamically adjust the size of the groove 12 to make it adapt to spring wires of different diameter specifications.

[0046] For example: when processing a wire with a diameter of 0.6 mm, appropriately reduce the width of the groove 12 and deepen the depth of the groove 12 to ensure that the wire is reliably clamped; when changing to a 1.2 mm wire, loosen the embedding degree and expand the space of the groove 12 to avoid wire flattening caused by over-tight clamping or excessive driving resistance. Therefore, by only adjusting the connection degree of the male body 111 and the female body 112, high-precision feeding control for springs of different calibers can be achieved without replacing the roller assembly, significantly improving the flexible production capacity and operation convenience of the equipment.

[0053] S2. Feeding and straightening:

[0054] 1) Groove 12 dimension adjustment: According to the diameter of the selected wire, adjust the embedding depth between the male body 111 and the female body 112 through the control system, so as to adjust the width and depth of the V-shaped groove 12 to achieve the best clamping effect.

[0055] 2) Straightening treatment: Start the straightening component 4, and use the feeding wheel 11 to preliminarily straighten the material; ensure that the wire remains straight before entering the forming component 2 to reduce quality problems caused by bending.

The above is common knowledge; therefore, the principle and structure are not described in detail herein.

[0062] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
