[0046] refer to Figure 1 and Figure 5 The spring manufacturing and conveying system provided in this application includes a spring coiling machine, a conveying device 3, and a positioning device 4. The spring coiling machine is used to coil steel wire into springs; the conveying device 3 is located on one side of the spring coiling machine where the springs are output and is used to convey the springs; the positioning device 4 includes a positioning member 41, which is located at the output end of the spring coiling machine. The wound spring is sleeved on the positioning member 41 and is used to guide the wound spring to fall vertically to a designated position on the conveying device 3.

[0047] After the spring coiling machine coils the steel wire into shape, it guides the coiled spring to the conveying device 3 through the positioning device 4 set at the output end. The positioning member 41 is located at the center of the spring formed after coiling, and the spring slides along the positioning member 41 and is conveyed to the conveying surface of the conveying device 3, so that the finished springs can be continuously output in sequence along the spring coiling machine, the positioning device 4 and the conveying device 3, without adding additional processes, which is efficient and convenient, thereby improving production efficiency.

[0048] It should be noted that the positioning member 41 can also be set to any position and angle that can convey the spring to the conveying device 3, and is not limited to being set in the vertical direction to guide the rolled spring to fall vertically to the conveying device 3.

[0049] refer to Figure 5 As an optional embodiment, the positioning device 4 also includes a telescopic drive mechanism 42, which is connected to the positioning member 41 and is used to drive the positioning member 41 to extend and retract, so that the free end of the positioning member 41 extends close to or away from the conveying device 3 to a specified position and guide the spring.

[0050] As an optional embodiment, when the spring is conveyed to the conveying device 3, the telescopic drive mechanism 42 drives the free end of the positioning member 41 close to the conveying device 3, and the distance between the positioning member 41 and the conveying surface of the conveying device 3 is less than the height of the spring, so as to guide the spring to be conveyed to the conveying device 3;

[0051] When the spring reaches the conveying device 3 , the free end of the positioning member 41 is away from the conveying device 3 , and the distance between the free end of the positioning member 41 and the conveying surface of the conveying device 3 is greater than the height of the spring, so that the conveying device 3 can deliver the spring.

[0052] The spring is guided down to a designated position by positioning device 4, with positioning member 41 positioned at the center of the coiled spring. When the spring needs to be lowered to the conveyor belt for transport, telescopic drive mechanism 42 causes positioning member 41 to extend closer to conveyor 3, ensuring that the distance between positioning member 41 and the conveying surface of conveyor 3 is less than the height of the spring. The spring then slides along positioning member 41 and is transported to the surface of conveyor 3. Once the spring is stably positioned on the conveying surface of conveyor 3, telescopic drive mechanism 42 causes positioning member 41 to retract, disengaging the spring from the conveying surface of conveyor 3. The distance between the free end of positioning member 41 and the conveying surface of conveyor 3 is greater than the height of the spring, allowing conveyor 3 to deliver the spring. In this manner, the telescopic drive mechanism 42 drives positioning member 41 up and down for guidance, enabling faster, smoother, and more continuous and orderly transport and guidance of the spring to conveyor 3.

[0053] refer to Figure 1-Figure 3 As an optional embodiment, the spring winding machine includes a wire feeding device 1, a forming device 2 and a wire cutting device 5. The wire feeding device 1 is used to clamp and convey the steel wire; the forming device 2 includes a forming wheel 21 and a thimble 22. The forming wheel 21 is arranged on one side of the wire feeding device 1, and a forming groove 211 is provided corresponding to the output end of the wire feeding device 1, which is used to guide the steel wire to be wound into a spiral spring along the direction of the forming groove 211. The thimble 22 is provided at the output end of the forming groove 211, and is used to apply external force to the wound spring to change the pitch and shape of the spring; the wire cutting device 5 includes a cutter 51 and a cutting drive mechanism (not shown in the figure). The cutter 51 is provided at the output end of the wire feeding device 1 and is used to cut the steel wire. The cutting drive mechanism is connected to the cutter 51 and is used to drive the cutter 51 to move to cut the steel wire.

[0054] The raw steel wire, gripped and transported by the wire feeder 1, moves along the conveying direction to the output end of the wire feeder 1 and is fed into the forming groove 211 of the forming device 2, where it abuts and contacts the inner wall of the forming groove 211. Under the action of the inner wall of the forming groove 211, the raw steel wire gradually bends and deforms in the direction of the forming groove 211. Driven by the wire feeder 1, the raw steel wire is pushed out of the output end of the forming groove 211 to form a spring. The ejector pin 22 then acts on the surface of the spring pushed out of the output end, changing its orientation and position relative to the forming groove 211, thereby altering the spring's pitch and shape, ultimately producing the desired spring. The forming groove 211 of the forming wheel 21 can be set to the desired spring output angle. The forming wheel 21, equipped with the forming groove 211, guides and restricts the deformation direction of the raw steel wire, allowing the finished spring to naturally turn and be output in the direction of the forming groove 211. The wire is cut by the wire shearing device 5. During cutting, the cutting drive mechanism drives the cutter 51 to swing and act on the wire. The cutting drive mechanism may include a drive motor and a slider-crank mechanism, and the drive force of the drive motor is transmitted to the cutter 51 through the slider-crank mechanism.

[0055] refer to Figure 4 As an optional embodiment, the forming wheel 21 includes a wheel body 212 and a movable mechanism 213. The wheel body 212 is rotatably arranged on the movable mechanism 213, and the forming groove 211 is arranged on the circumference of the wheel body 212. The input end of the forming groove 211 corresponds to the position of the output end of the wire feeding device 1. This allows the steel wire to accurately enter the forming groove 211 when it is output from the wire feeding device 1, so as to avoid the failure of the spring to be wound due to the deviation of the steel wire position. The movable mechanism 213 is connected to the wheel body 212, and is used to drive the wheel body 212 to move horizontally, so as to change the position and distance of the wheel body 212 relative to the wire feeding device 1, and then change the diameter of the spring and the curvature of the bending. The impact force of the steel wire causes the wheel body 212 to rotate, so that the forming groove 211 continuously receives the steel wire during the rotation process, and the rotating wheel body 212 forces the steel wire to bend for winding.

[0056] In some embodiments, the movable mechanism 213 includes a drive motor and a transmission mechanism. The transmission mechanism may be a slider-crank mechanism or a crank-rocker mechanism, which transmits the driving force of the drive motor to the wheel body 212 through the slider-crank mechanism or the crank-rocker mechanism, thereby driving the wheel body 212 to move relative to the wire feeding device 1, such as reciprocating relative to the conveying direction of the wire feeding device 1 or moving perpendicular to the conveying direction.

[0057] refer to Figure 4 As an optional embodiment, the ejector pin 22 includes a pin body 221 and a reciprocating drive mechanism 222. The pin body 221 is disposed at the output end of the forming groove 211. The reciprocating drive mechanism 222 is connected to the pin body 221 and is used to drive the pin body 221 away from or close to the forming groove 211.

[0058] Driven by the reciprocating drive mechanism 222, the needle body 221 performs linear reciprocating motion, such as in a vertical direction. Depending on manufacturing requirements, the ejector pin 22 can be positioned relative to the forming wheel 21 at any angle or position to act upon the surface of the curved spring formed by the coiled wire. During the spring coiling process, after the wire is bent through the forming groove 211 on the forming wheel 21, the ejector pin 22 pushes the spring wire to change the spring pitch, thereby winding the spring into a desired shape. The ejector pin 22 can also adjust the direction and angle of the spring after manufacture.

[0059] refer to Figure 2 As an optional embodiment, the wire feeding device 1 includes a pair of wire pressing wheels 11. The wire pressing wheels 11 are distributed vertically, and the rotating axes of the wire pressing wheels 11 are parallel to each other. The two wire pressing wheels 11 rotate in the conveying direction, that is, when they rotate in opposite directions, they clamp and convey the steel wire in the horizontal direction. The opposing forces generated by the paired wire pressing wheels 11 on the steel wire clamp the steel wire, facilitating the conveyance of the steel wire.

[0060] As an optional embodiment, a wire passing groove 111 is provided on the surface of at least one wire pressing wheel 11, and the wire passing groove 111 is used to limit the position of the steel wire.

[0061] As an optional implementation, the wire groove 111 is triangular or arc-shaped.

[0062] The wire groove 111 increases the contact area between the steel wire and the wire pressing wheel 11 during transportation, and at the same time provides guidance and limitation for the steel wire, making the transmission more stable and preventing the steel wire from deflecting or falling off during transportation.

[0063] In some embodiments, at least one crimping wheel 11 is connected to a crimping wheel moving mechanism to drive the two crimping wheels 11 arranged in pairs to move away from or closer to each other to clamp or release the wire. The crimping wheel moving mechanism can be a cylinder or a spring expansion mechanism.

[0064] refer to Figure 2 As an optional embodiment, the wire feeding device 1 further includes a guide member 12, which is disposed at the output end of the wire pressing wheel 11 and is provided with a wire groove 121. The inlet of the wire groove 121 corresponds to the position of the output end of the wire pressing wheel 11, and the outlet of the wire groove 121 corresponds to the input end of the forming groove 211. The wire groove 121 is used to guide the direction of the raw material. This improves the position accuracy of the raw material during the conveying process and enhances the continuity and reliability of the spring during the automated production process.

[0065] refer to Figure 1As an optional embodiment, the conveying device 3 includes a conveyor belt 31 and a magnet 32. The conveyor belt 31 is provided on the side where the springs are output from the forming device 2, and is used to transport the springs along the transmission direction of the conveyor belt 31. The magnet 32 is provided on the conveying surface of the conveyor belt 31 to attract the springs.

[0066] The spring is transported along the transmission direction of the conveyor belt 31 by the conveyor belt 31 in the conveying device 3. The magnet 32 is arranged on the conveying surface of the conveyor belt 31 so that the spring is firmly adsorbed on the surface of the conveyor belt 31, so that it is transported smoothly.

[0067] In some embodiments, the magnet 32 can be disposed at any position that allows the spring to be attracted to the conveying surface of the conveyor belt 31. For example, the magnet 32 can be disposed in a layer on the side of the conveyor belt 31 opposite to the conveying surface, or can be disposed directly on the conveying surface of the conveyor belt 31.

[0068] The embodiments of the present application are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only intended to help understand the method and core ideas of the present application. At the same time, changes or modifications made by those skilled in the art based on the ideas of the present application, the specific implementation methods, and the scope of application of the present application, all fall within the scope of protection of the present application. In summary, the contents of this specification should not be construed as limiting the present application.
