Description

Technical Field

[0001] This utility model belongs to the technical field of spring production equipment, specifically relating to a spring machine and its wire feeding mechanism. Background Technology

[0002] Springs, as important mechanical components, are widely used in numerous industrial fields such as automobiles, electronics, home appliances, and medical devices. Spring machines are specialized equipment used to produce various springs, one of their core functions being the bending and shaping of metal wire into predetermined shapes. The wire feeding mechanism, a key component of the spring machine, is responsible for the stable and precise delivery of the wire to the processing area; its performance directly affects the spring forming accuracy, production efficiency, and equipment stability.

[0003] Traditional wire feeding mechanisms typically employ a simple roller pressing method, using one or more pairs of drive rollers to clamp the wire and push it forward through friction. However, this type of mechanism has some inherent drawbacks: First, its feeding action is usually only a simple linear motion, making it difficult to meet the process requirements of simultaneously pushing and rotating the wire in the processing of complex springs (such as irregularly shaped springs or three-dimensional spatial springs); second, during high-speed wire feeding, the mechanism is prone to significant vibration, leading to inconsistent wire lengths and affecting product accuracy; furthermore, when it is necessary to change wire specifications or adjust the feeding angle, traditional mechanisms are cumbersome to adjust and have poor adaptability. Utility Model Content

[0004] To solve the above-mentioned technical problems, the first objective of this utility model is to provide a wire feeding mechanism that can simultaneously push the wire during the processing, thus meeting the processing requirements of complex spring products; the second objective of this utility model is to provide a spring machine.

[0005] To achieve the first objective of the above-mentioned utility model, the present utility model adopts the following technical solution: A wire feeding mechanism includes a frame, a sliding frame, a feeding box, and a discharging assembly. A support plate is fixed to the upper part of the frame, and the sliding frame is slidably mounted on the support plate. A motor A is fixed to the lower part of the support plate. The rotating shaft of motor A passes through the support plate, and a disc is fixed on the rotating shaft. A protruding post A is eccentrically mounted on the disc. A protruding post B is also provided at the bottom of the sliding frame. A connecting rod A is provided between protruding posts A and B, with both ends of the connecting rod rotatably connected to protruding posts A and B, respectively. The feeding box is fixed to the sliding frame, and the discharging assembly is located at the front end of the sliding frame, with its rear end connected to the front end of the feeding box. A mounting plate is fixed to the frame, and a through hole is opened in the middle of the mounting plate. Motor A drives the sliding frame to move via connecting rod A, thereby causing the discharging assembly to extend and retract within the through hole.

[0006] As a preferred embodiment, the sliding frame includes a front mounting plate, a sliding base plate, and side support plates fixed to each other. The discharge assembly is rotatably connected to the front mounting plate, and a rotating gear disk is fixed on the discharge assembly. A rotary drive motor is also fixed on the front mounting plate. The rotating shaft of the rotary drive motor is driven by the rotating gear disk through gear meshing, thereby driving the discharge assembly to rotate.

[0007] As a preferred embodiment, the discharge assembly includes a discharge column, a connecting pipe, and a rotating pipe. The rotating gear disk is fixed at one end of the rotating pipe, the discharge column is located at the other end of the rotating pipe, and is enclosed and secured by two semi-circular clamping blocks. The connecting pipe is located at one end of the discharge column and extends to the feeding box. A fixing block is sleeved on the outside of the rotating pipe through a bearing, and the fixing block is fixed to the front mounting plate.

[0008] As a preferred embodiment, the feeding box includes a drive box and multiple sets of rollers disposed on one side of the drive box and driven by the drive box. Each set of rollers includes two rollers that are fitted together vertically. The circumferential surface of the rollers is provided with a groove. One end of the connecting tube is conical and extends into the front end of the fitting area of ​​the two rollers. The connecting tube is hollow inside.

[0009] As a preferred embodiment, the side support plate is also provided with a rectangular through hole to avoid the drive box, a guide rail A is fixed on the support plate, and a slider A is provided at the bottom of the sliding base plate. The sliding frame is slidably connected to the frame through the cooperation of the guide rail A and the slider A.

[0010] As a preferred embodiment, a crossbeam is fixed between the side support plates on both sides. The crossbeam is located at the rear end of the feeding box, and a vertical guide wheel assembly is fixed on the crossbeam. A horizontal guide wheel assembly is fixed at the rear end of the vertical guide wheel assembly.

[0011] To achieve the second objective of the above-mentioned utility model, the present utility model adopts the following technical solution: A spring machine includes a wire feeding mechanism as described in any of the above claims, wherein the mounting plate is provided with multiple sets of tool telescopic assemblies and / or tool multi-dimensional movement assemblies, and the tool telescopic assemblies and tool multi-dimensional movement assemblies are arranged around the discharge assembly.

[0012] As a preferred embodiment, both the multi-dimensional movement component and the telescopic component of the cutting tool include a support block, a sliding plate, a connecting rod B, and a motor B. The sliding plate is slidably mounted on the support block along its length. The motor B is fixed to one end of the support block, and a turntable is fixed to the shaft of the motor B. A connecting column is eccentrically mounted on the turntable. One end of the connecting rod B is rotatably connected to the connecting column, and the other end is rotatably connected to the sliding plate. A cutting head is also fixed on the sliding plate of the telescopic component of the cutting tool. A cutting tool is also movably mounted on the sliding plate of the multi-dimensional movement component of the cutting tool.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a motor A to drive a disc, which in turn drives a sliding frame via a connecting rod A, converting the motor's rotational motion into precise linear reciprocating motion. Compared to traditional cylinder or hydraulic drives, this crank-slider mechanism offers smoother movement, more precise control (the feeding length can be precisely controlled by adjusting the motor's rotation angle), and faster speed, making it ideal for high-frequency feeding requirements.

[0014] Meanwhile, the feeding box (providing feeding power) and the discharge assembly (guiding the wire direction) of this invention are both integrated on the sliding frame. Therefore, when motor A drives the device, the entire feeding end (discharge assembly) will move synchronously with the sliding frame. This ensures that the wire discharge point itself is moving during the feeding process, greatly reducing the relative friction and scratching between the wire and the discharge port, which is particularly beneficial for conveying precision wires with high surface finish requirements.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments: like Figures 1 to 7 The spring machine shown includes a frame 1, a sliding frame 2, a feeding box 3, and a discharge assembly 30. A support plate 12 is fixed to the upper part of the frame 1. The sliding frame 2 is slidably mounted on the support plate 12. A motor A11 is fixed to the lower part of the support plate 12. The rotating shaft of the motor A11 passes through the support plate 12, and a disc is fixed on the rotating shaft. A protruding post A is eccentrically mounted on the disc. A protruding post B is also provided at the bottom of the sliding frame 2. A connecting rod A111 is provided between the protruding posts A and B. The two ends of the connecting rod A111 are rotatably connected to the protruding posts A and B, respectively. The feeding box 3 is fixed to the sliding frame 1. On the frame 2, the discharge assembly 30 is located at the front end of the sliding frame 2 and its rear end is connected to the front end of the feeding box 3. The frame 1 is fixed with a mounting plate 5, and side plates 51 are fixed on both sides of the mounting plate 5. A through hole is opened in the middle of the mounting plate 5. The motor A11 drives the sliding frame 2 to move through the connecting rod A111, thereby driving the discharge assembly 30 to extend and retract within the through hole. The mounting plate 5 is also provided with multiple sets of tool extension assemblies 6 and / or tool multi-dimensional movement assemblies 7, and the tool extension assemblies 6 and tool multi-dimensional movement assemblies 7 are arranged around the discharge assembly 30. An operation control assembly 9 is also provided on one side of the frame.

[0025] In the above structure, the discharge assembly extends and retracts within a through-hole in the mounting plate, which serves as a fixed reference point. The cutting tool system can be arranged around this through-hole, ensuring that the outlet remains within the working range of the cutting tool regardless of the extension or retraction of the discharge assembly, thus guaranteeing the stability and consistency of the forming process. Simultaneously, the drive motor A is positioned below the support plate, transmitting power through a compact linkage mechanism, saving horizontal installation space and making the entire frame structure more stable and with more rational stress distribution.

[0026] The sliding frame 2 includes a front mounting plate 21, a sliding base plate 22, and side support plates 23 fixed to each other. The discharge assembly 30 is rotatably connected to the front mounting plate 21, and a rotating gear disk 303 is fixed on the discharge assembly 30. A rotary drive motor 24 is also fixed on the front mounting plate 21. The rotating shaft of the rotary drive motor 24 is driven by the rotating gear disk 303 through gear meshing, thereby driving the discharge assembly 30 to rotate.

[0027] In the above structure, the rotary drive motor 24 is independently mounted on the sliding frame, without interfering with the linear motion motor A, and can be controlled independently, achieving precise coordinated motion of two degrees of freedom. Simultaneously, through the rotary drive motor and gear transmission, the entire discharge assembly can be driven to rotate around its axis, thus freeing the fed wire from being confined to a fixed direction and enabling flexible adjustment of the discharge direction. This structure allows a single spring machine to easily produce complex springs that are difficult to process with traditional equipment, expanding its processing capabilities. For example, three-dimensional springs (such as irregularly shaped springs and conical springs): by changing the discharge angle during feeding and coordinating with the movement of the cutting tool, they can be bent into three-dimensional shapes. Another example is springs with a special angle at the end: by rotating the spring end at an angle as it is delivered, it can be bent or cut.

[0028] The discharge assembly 30 includes a discharge column 300, a connecting pipe 301, and a rotating pipe 302. The rotating gear disk 303 is fixed at one end of the rotating pipe 302. The discharge column 300 is located at the other end of the rotating pipe 302 and is fastened by two semi-circular clamping blocks 306. The connecting pipe 301 is located at one end of the discharge column 300 and extends to the feeding box 3. A fixing block 305 is sleeved on the outside of the rotating pipe 302 through a bearing 304. The fixing block 305 is fixed to the front mounting plate 21.

[0029] The discharge column in the above structure is secured by two semi-circular ring clamps. This means that when different wire diameters need to be processed, only the corresponding discharge column and connecting tube need to be replaced. The replacement is convenient and greatly improves the versatility and production changeover efficiency of the equipment. In addition, the rotating tube in the above structure is supported on the front mounting plate by bearings and fixed blocks. This design ensures the concentricity and stability of the discharge assembly when rotating at high speed, avoids vibration, and thus ensures the wire feeding accuracy.

[0030] The feeding box 3 includes a drive box 32 and multiple sets of rollers 31 disposed on one side of the drive box 32 and driven by the drive box 32. Each set of rollers includes two rollers 31 that are fitted together vertically. The circumferential surface of the rollers 31 is provided with a groove. One end of the connecting tube 301 is conical and extends into the front end of the fitting area of ​​the two rollers 31. The connecting tube 301 is hollow inside.

[0031] The above structure adopts a multi-set upper and lower roller design, which clamps the wire through grooves, providing strong driving force and stable friction to ensure that the wire is continuously and evenly pushed, overcoming the problem of possible slippage of a single pair of rollers; and the conical end of the connecting tube extends precisely into the front end of the mating point of the two sets of rollers. This structure can catch the wire delivered from the rollers and immediately guide it into a stable guide pipe (connecting tube and discharge column), realizing a "zero gap" transition from driving to guiding, which is a key detail to ensure smooth and non-jumping wire feeding.

[0032] The side support plate 23 is also provided with a rectangular through hole to avoid the drive box 32. A guide rail A121 is fixed on the support plate 12, and a slider A122 is provided at the bottom of the sliding base plate 22. The sliding frame 2 is slidably connected to the frame through the cooperation of the guide rail A121 and the slider A122. The above structure ensures high precision and stability of linear motion, while the rectangular through hole designed to avoid the drive box optimizes the spatial layout and ensures structural rationality.

[0033] A crossbeam 25 is fixed between the side support plates 23 on both sides. The crossbeam 25 is located at the rear end of the feeding box 3. A vertical guide wheel assembly 40 is fixed on the crossbeam 25, and a horizontal guide wheel assembly 4 is fixed at the rear end of the vertical guide wheel assembly 40. The horizontal and vertical guide wheel assemblies at the rear end of the feeding box can perform preliminary straightening and positioning of the wire coming from the wire reel, ensuring that the wire can enter the feeding rollers in the correct and centered posture.

[0034] The tool telescopic assembly 6 is fixed on the mounting plate 5, and the tool multi-dimensional moving assembly 7 is slidably mounted on the mounting plate 5. The tool telescopic assembly 6 and the tool multi-dimensional moving assembly 7 are arranged around the telescopic rotating discharge assembly 30. The tool multi-dimensional moving assembly 7 and the tool telescopic assembly 6 each include a support block 61, a sliding plate 62, a connecting rod B63, and a motor B8. The sliding plate 62 is slidably mounted on the support block 61 along its length. The motor B8 is fixed to one end of the support block 61. A turntable 64 is fixed on the rotating shaft of the motor B8. A connecting column 65 is eccentrically mounted on the turntable 64. One end of the connecting rod B63 is rotatably connected to the connecting column 65, and the other end is rotatably connected to the sliding plate 62. A tool head 66 is also fixed on the sliding plate 62 of the tool telescopic assembly 6. A tool is also movably mounted on the sliding plate 62 of the tool multi-dimensional moving assembly 7.

[0035] The aforementioned structure also employs an eccentric wheel and connecting rod mechanism for tool drive (similar to the main feed drive principle). This mechanism is well-suited for scenarios requiring high-frequency, short-stroke reciprocating motion. It features a simple structure, fast response, and reliable operation, making it ideal for the rapid movement requirements of spring machine tools. Furthermore, a tool telescopic assembly (for directly fixing the tool head and using it for simple actions such as pushing and cutting) and a multi-dimensional tool movement assembly (for mounting more complex movable tools and using them for more complex forming actions) are designed, demonstrating the versatility and expandability of the equipment's functions.

[0036] This invention relates to a spring-making machine that combines an innovative wire feeding mechanism with a surrounding tool system, forming a fully functional machining center. The wire feeding mechanism is responsible for precise material feeding and angle setting, while the tool assembly is responsible for bending and cutting. Working together, they can efficiently and effectively manufacture complex springs. This invention's spring-making machine boasts advantages such as high-precision reciprocating feeding, rotating discharge port, and stable drive, resulting in a significant improvement in its overall performance.
