[0034] The utility model provides a spring forming device.

[0035] See also Figure 1 and Figure 2 In one embodiment of the utility model, the spring forming device includes a base 10, a winding mechanism 20 and a discharging mechanism 30; the winding mechanism 20 includes a moving component 21 and a winding and forming table 22 connected to the moving component 21, and the moving component 21 is movably connected to the base 10; the discharging mechanism 30 is movably connected to the base 10, and is used to discharge the steel wire; wherein the discharging mechanism 30 discharges the steel wire to the winding and forming table 22, so that the steel wire is wound along the winding and forming table 22 to be formed into a spring.

[0036] When the spring forming device is started, the moving assembly 21 drives the winding and forming table 22 to approach the discharging mechanism 30, and then the discharging mechanism 30 delivers the steel wire to the winding and forming table 22. At the moment when the discharging mechanism 30 pushes out the steel wire, the steel wire can be wound along the circumferential outer wall of the winding and forming table 22 under the thrust of the discharging mechanism 30, and gradually formed into a spring. In this embodiment, the circumferential position of the steel wire discharged from the discharging mechanism 30 is limited at the winding and forming table 22 of the winding mechanism 20, so that the steel wire forms a flat spring during the winding and forming process, thereby improving the spring forming effect.

[0037] The spring forming device has a reasonable structural design, and effectively improves the automation level of spring production through the organic combination of the base 10, the winding mechanism 20 and the discharging mechanism 30. The cooperation between the moving component 21 and the winding forming table 22 realizes the efficient winding of the steel wire, improves the production efficiency and reduces the labor cost.

[0038] The movable connection mode of the movable component 21 allows the winding and forming table 22 to be closer to or farther away from the discharge mechanism 30, so that the winding and forming table 22 can flexibly adapt to the winding requirements of steel wires of different specifications, which not only improves the versatility of the equipment, but also ensures that the force on the steel wire is uniform during the winding process, thereby significantly improving the quality of the finished spring.

[0039] Optionally, the moving assembly 21 includes a moving arm and a cylinder connected to the moving arm, the cylinder is fixed to the base 10, and the winding forming table 22 is fixed to the end of the moving arm away from the cylinder; the cylinder drives the moving arm to retract or extend, so that the moving arm is away from or close to the discharge mechanism 30. Of course, the moving assembly 21 can also be a combination of a motor, a screw rod and a moving arm, or the moving assembly 21 can also be a combination of a motor, a rack, a gear, a slider, that is, a moving arm.

[0040] Optionally, the discharging mechanism 30 is movably connected to the base 10, and its main function is to discharge the steel wire to the winding and forming table 22. The discharging mechanism 30 includes: a steel wire storage drum, a driving device and a guiding device. The steel wire storage drum is used to store the steel wire to be processed; the driving device is used to drive the steel wire to be discharged smoothly from the steel wire storage drum; and the guiding device is used to ensure that the steel wire maintains the correct direction during the discharging process.

[0041] In one embodiment, see Figure 1 and Figure 2 The winding and forming table 22 includes a connecting arm 221 and a forming body 222. The connecting arm 221 is detachably connected to the moving component 21; the forming body 222 is connected to one end of the connecting arm 221 away from the moving component 21, and the forming body 222 is used for winding and forming the steel wire along its outer wall.

[0042] The detachable connection between the connecting arm 221 and the moving assembly 21 is one of the technical features, and its advantage is that it is easy to maintain and replace; the design of the forming body 222 allows the steel wire to be smoothly wound along its outer wall, thereby improving production efficiency. The forming body 222 is connected to the end of the connecting arm 221 away from the moving assembly 21, and is used for the steel wire to be wound along its outer wall.

[0043] The steel wire is placed on the outer wall of the forming body 222, and the moving assembly 21 is started to wind the steel wire along the outer wall of the forming body 222. When the winding and forming is completed, the moving assembly 21 is controlled to drive the connecting arm 221 and the forming body 222 away from the discharging mechanism 30, so that the connecting arm 221 and the forming body 222 are reset, so that the formed spring is separated from the forming body 222, and the spring forming is completed.

[0044] Optionally, the connecting arm 221 is designed with an adjustable length to meet the winding requirements of steel wires of different specifications.

[0045] Optionally, the outer wall of the molding body 222 is designed as a replaceable module to facilitate replacement of the molding mold according to the needs of different products.

[0046] In one embodiment, see Figure 1 and Figure 2 , the molding body 222 is a cylindrical molding body.

[0047] The forming body 222 can adopt a hollow cylindrical shell or a solid cylindrical body; with this configuration, the outer peripheral wall of the forming body 222 can form an arc path for winding the steel wire, making it easier to wind the steel wire into a regular spring, thereby improving the forming effect of the spring.

[0048] The forming body 222 is made of a material that is resistant to high temperatures and wear, such as stainless steel or ceramic. The forming body 222 has a certain strength and rigidity and can withstand the pressure generated during the forming process. In this embodiment, the shape of the forming body 222 is cylindrical, but the utility model is not limited to this shape, and forming bodies 222 of other shapes can also adopt the utility model. The material, size, mold structure, etc. of the forming body 222 can be adjusted according to actual needs.

[0049] In one embodiment, see Figure 1 and Figure 2 The circumferential outer wall of the forming body 222 is provided with a winding groove 222 a, and the winding groove 222 a is arranged around the circumferential outer wall of the forming body 222 .

[0050] By setting a winding groove 222a on the circumferential outer wall of the forming body 222, the steel wire can not only fit more closely to the forming body 222 during the forming process, but also be wound only in the limited space of the winding groove 222a, so that the steel wire can be wound to form a dense spring, avoiding the loose winding of the spring, ensuring the quality of the finished spring, reducing material waste, and effectively improving material utilization and forming efficiency.

[0051] The winding groove 222a is arranged around the circumferential outer wall of the forming body 222, so that the winding object can be closely attached to the forming body 222 during the winding process, thereby improving the winding effect. The arrangement of the winding groove 222a is conducive to reducing the slippage of the winding object during the winding process and improving the winding stability. In addition, the design of the winding groove 222a can also prevent the winding object from falling off during the winding process, thereby ensuring the winding quality.

[0052] Specifically, the circumferential outer wall of the molding body 222 is cylindrical, and the winding grooves 222a are evenly distributed along the circumferential direction of the circumferential outer wall. The transverse cross-sectional shape of the winding grooves 222a can be rectangular, V-shaped, U-shaped or spiral, etc., and its depth can be adjusted according to actual needs to adapt to windings of different diameters. In the manufacturing process, the setting of the winding grooves 222a can be molded, machined or laser engraved.

[0053] The number of the winding grooves 222a is not limited to the above number, and the number of the winding grooves 222a can be adjusted according to actual needs. For example, two winding grooves 222a are provided, and the two winding grooves 222a can be arranged at intervals along the circumferential height of the forming body 222, so that two springs can be wound respectively using the two winding grooves 222a at one time, further improving the forming efficiency of the spring.

[0054] In one embodiment, see Figure 1 and Figure 2 The winding groove 222a is located at an end of the molding body 222 away from the connecting arm 221.

[0055] In this embodiment, the winding groove 222a is arranged at one end of the forming body 222 away from the connecting arm 221. In this way, the forming body 222 only needs to move a small position to arrange the winding groove 222a corresponding to the discharge mechanism 30, thereby shortening the moving distance of the moving component 21 and accelerating the forming efficiency of the spring forming device.

[0056] In one embodiment, see Figure 1 and Figure 2 The forming body 222 includes a fixed block and a winding block, the fixed block is connected to the connecting arm 221; the winding block is detachably connected to one end of the fixed block away from the connecting arm 221; the winding block is provided with a winding groove 222a.

[0057] By making the fixing block and the winding block detachable, on the one hand, a modular design of the forming body 222 is achieved. This design makes the connection between the components more flexible and facilitates installation and maintenance; on the other hand, winding blocks of different sizes can be used. The winding blocks of different sizes can have different diameters or different depths of the winding grooves 222a on the winding blocks.

[0058] Optionally, one end of the fixing block is fixedly connected to one end of the connecting arm 221 by a bolt. The winding block is detachably connected to one end of the fixing block away from the connecting arm 221, and a buckle that can be matched with a slot on the fixing block is provided at the connecting end of the winding block, and the detachable connection between the winding block and the fixing block is achieved through the cooperation between the buckle and the slot.

[0059] Optionally, the fixed block is connected to the connecting arm 221 in a rotatable manner. A rotating shaft is provided at one end of the fixed block, and the rotating shaft passes through the shaft hole of the connecting arm 221 and realizes the rotating connection through a bearing. This design allows the fixed block to rotate relative to the connecting arm 221, thereby facilitating the adjustment of the winding angle and direction of the winding block.

[0060] In one embodiment, see Figure 1 and Figure 2 The connecting arm 221 and the molded body 222 are an integrally molded structure.

[0061] The connecting arm 221 and the forming body 222 are both made of the same material, or the connecting arm 221 and the forming body 222 are welded or bonded to form an integral structure, so that the winding and forming table 22 has a high structural strength and reliability. Secondly, the integrally formed structure reduces the assembly gap between the components, reduces the vibration and noise in a dynamic working environment, thereby improving the working performance of the winding and forming table 22.

[0062] In one embodiment, see Figure 1 and Figure 2 The forming body 222 is provided with an avoidance groove 222 b, and the avoidance groove 222 b extends from the center of the forming body 222 to the circumferential outer wall of the forming body 222.

[0063] In this embodiment, an avoidance groove 222b is set on the forming body 222, so that after the moving component 21 drives the forming body 222 to approach the discharging mechanism 30, the avoidance groove 222b not only allows the discharging mechanism 30 to be closer to the forming body 222, but also allows the discharging mechanism 30 to move during discharging, providing a certain buffer space, thereby avoiding or reducing the damage of the discharging mechanism 30 to the forming body 222, thereby making the spring forming device more stable and smooth in molding.

[0064] Specifically, the forming body 222 is a cylindrical structure, and the avoidance groove 222b starts from the central axis position of the forming body 222 and extends outward along the axis direction until it reaches the circumferential outer wall of the forming body 222. The shape of the avoidance groove 222b can be rectangular, circular or other suitable shapes, and its size is designed according to actual needs. The depth, width and length of the avoidance groove 222b can be adjusted according to the actual process requirements and the structural characteristics of the molded product. The connection part between the forming body 222 and the avoidance groove 222b: a transition structure is designed to make the connection between the avoidance groove 222b and the forming body 222 smoother to avoid stress concentration.

[0065] In one embodiment, see Figure 1 and Figure 2 The molded body 222 is also provided with a weight-reducing groove 222c, and the weight-reducing groove 222c is connected to the avoidance groove 222b.

[0066] By providing the weight-reducing groove 222c, the overall weight of the forming body 222 can be effectively reduced, thereby achieving the purpose of reducing the burden on the equipment and reducing energy consumption. In addition, the reduced weight improves the flexibility and convenience of the forming body 222 during movement and operation. Secondly, the connection between the weight-reducing groove 222c and the avoidance groove 222b optimizes the structural design of the forming body 222, can better avoid and adjust the discharging mechanism 30, and improves the flexibility of production and the accuracy of the product.

[0067] The forming body 222 is made of high-strength metal material, and a weight-reducing groove 222c and an avoidance groove 222b are provided inside the forming body 222. The weight-reducing groove 222c is serpentine, extending from one side of the forming body 222 to the other side, and is connected to the avoidance groove 222b. This design achieves the purpose of reducing weight. The design of the weight-reducing groove 222c reduces the overall weight while maintaining the strength of the forming body 222.

[0068] In one embodiment, see Figure 1 and Figure 2 The center of the weight-reducing groove 222 c is coaxially arranged with the center of the forming body 222 .

[0069] The device greatly improves the overall structural strength and stability of the product by setting the center of the weight-reducing groove 222c coaxially with the center of the forming body 222. In the prior art, since the setting of the weight-reducing groove 222c is often offset from the center of the forming body 222, stress concentration is easily generated when subjected to force, which reduces the service life of the product. The coaxial setting of the utility model effectively avoids this problem, ensuring that the product can be evenly distributed when subjected to external force, thereby significantly improving the durability and reliability of the product.

[0070] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
