Description

Technical Field

[0001] This utility model relates to the field of spring production technology, specifically a spring machine waste material recycling and winding mechanism. Background Technology

[0002] The spring machining process is automated. First, the spring wire is smoothly released from the spool by the wire feeding frame. The straightening mechanism corrects the curvature of the wire to ensure straightness. Then, the wire feeding mechanism accurately feeds the wire according to the set parameters. Subsequently, under the control of the CNC system, the wire is wound into a specific spiral or irregular structure according to the design requirements of the spring type using core forming components such as the winding shaft, guide wheel, and cam, and the shape is completed. After forming, the cutting mechanism accurately cuts the spring from the wire. After grinding and deburring, the finished spring product that meets the specifications is finally produced.

[0003] After the required production quantity of springs is reached, a certain length of excess material remains in the spring machine. Because this excess material has been straightened or partially shaped by the spring machine, its shape has changed. If it is rewound onto the reel, it is prone to tangling or deformation, making it difficult to guarantee the accuracy of subsequent use. Therefore, this excess material is not rewound onto the reel but is directly cut off and discarded. In actual production, after this cut-off excess material is discharged from the spring machine, it is bent and rewound by workers to reduce its length for easier recycling later. However, manually bending and rewinding this excess material undoubtedly increases the labor intensity of workers and is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a spring machine waste material recycling and winding mechanism, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A spring machine waste material recycling and winding mechanism includes a frame plate and a U-shaped seat. The U-shaped seat is installed below the frame plate. A disc seat is rotatably mounted on one side of the U-shaped seat, and a drive unit is provided on the other side. A winding bar is fixed on one side of the disc seat, and a pushing unit is provided on the other side. The winding bar and the disc seat are arranged coaxially. The winding bar is hollow and has an opening at one end and a sealed end. The open end of the winding bar is located away from the disc seat. A transverse groove extending along its length is provided on the winding bar, and the transverse groove communicates with the inner cavity of the winding bar and passes through the open end of the winding bar. The drive unit is used to drive the disc seat to rotate, and the pushing unit is used to push the waste material wound on the winding bar away from the winding bar.

[0007] Furthermore, the pushing unit includes a pushing plate and a pushing cylinder; the pushing cylinder is fixed on one side end face of the disc seat, and the telescopic end of the pushing cylinder extends through to the other side of the disc seat, and the pushing plate is fixed thereto by a connecting rod; the pushing plate is movably fitted on the outer wall of the winding bar.

[0008] Furthermore, the drive unit includes a drive motor, a main gear, and a gear ring; a shaft is coaxially fixed to the side of the disc seat away from the winding bar, and the gear ring is fixed to the shaft; the drive motor is fixed to the side of the U-shaped seat away from the disc seat, and the main gear is fixed to the output shaft of the drive motor and meshes with the gear ring accordingly.

[0009] Furthermore, a vertical plate is fixed to one side of the shelf, and a guide rod extending along the length of the shelf is fixed to the vertical plate; sliding seats are fixed to the top of both sides of the U-shaped seat, and the two sliding seats are slidably fitted onto the guide rod.

[0010] Furthermore, a threaded rod is rotatably mounted through the side of the U-shaped seat away from the disc seat, and the threaded rod is fixed coaxially with the shaft; a threaded hole is provided on the vertical plate, and the threaded rod is threadedly matched and installed in the threaded hole.

[0011] Furthermore, the distance between the toothed ring and the disc seat is greater than the length of the pusher cylinder.

[0012] Furthermore, an anti-detachment cap is installed at the end of the threaded rod away from the shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] Driven by a drive unit, the winding bar rotates. Combined with the design that connects the horizontal groove on the winding bar to the inner cavity, the residual material discharged from the spring machine can be automatically wound up. After winding, the pusher cylinder drives the pusher plate to slide along the outer wall of the winding bar, pushing the residual material roll away from the winding bar, realizing automatic unloading. This replaces the traditional manual winding and collection of residual material, reduces the workload of workers, and has high operating efficiency.

[0015] The shaft drives the threaded rod to rotate synchronously. The threaded engagement between the threaded rod and the threaded hole drives the U-shaped seat to move in the opposite direction, so that the winding position of the take-up bar is adjusted synchronously, ensuring that the remaining material is evenly wound on the take-up bar. The coaxial fixed design of the shaft and the threaded rod eliminates the need for a separate drive component for the translation of the U-shaped seat, reducing drive costs. Moreover, the unified power source for winding and position adjustment ensures that the operation sequence of the two is coordinated. Attached Figure Description

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0024] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] Example 1

[0026] Please see Figures 1-5 This utility model provides a spring machine waste material recycling and winding mechanism, which includes a frame plate 1 and a U-shaped seat 3. It is worth noting that, as... Figure 5 As shown, the frame plate 1 is installed on the discharge side of the spring machine body 01 via the slide 03. The slide 03 can drive the frame plate 1 and the entire mechanism to reciprocate and adjust. The direction of movement is indicated by the arrow in the figure. During the spring processing, the slide 03 drives the frame plate 1 and the entire mechanism to move away from the spring machine body 01, which can make room around the discharge port on the side of the spring machine body 01, so as to facilitate the bending and cutting of the wire. When recycling the remaining material in the spring machine body 01, the slide 03 drives the entire mechanism to move closer to the spring machine body 01, so that the remaining material can be wound up and recycled.

[0027] Specifically, the U-shaped seat 3 of the frame plate 1 is installed below the frame plate 1. A disc seat 4 is rotatably mounted on one side of the U-shaped seat 3, and a drive unit 6 is provided on the other side. A winding rod 2 is fixed on one side of the disc seat 4, and a pushing unit 5 is provided on the other side. The winding rod 2 and the disc seat 4 are arranged coaxially. The winding rod 2 is hollow and has an opening at one end and a sealed end at the other. The opening end of the winding rod 2 is located away from the disc seat 4. A transverse groove 21 is provided on the winding rod 2, which extends along its length and communicates with the inner cavity of the winding rod 2. The transverse groove 21 also passes through the opening end of the winding rod 2. The drive unit 6 is used to drive the disc seat 4 to rotate, and the pushing unit 5 is used to push the excess material wound on the winding rod 2 away from the winding rod 2.

[0028] When the residual material is wound up and recycled, the drive unit 6 first drives the disc seat 4 to rotate, so as to drive the winding bar 2 to rotate and adjust until the horizontal groove 21 is aligned with the discharge port on the side of the spring machine body 01. Then, the wire is cut off between the wire reel 02 and the spring machine body 01, and the cut residual material is fed outward through the conveying mechanism inside the wire reel 02 until one end of the residual material is inserted into the winding bar 2 radially from the horizontal groove 21.

[0029] Subsequently, the drive unit 6 operates, driving the disc seat 4 and causing the winding bar 2 to rotate. Since one end of the residual material is held inside the winding bar 2, as the spring machine body 01 synchronously supplies the residual material, the residual material can be gradually rolled up on the winding bar 2 as it rotates, eventually forming a residual material roll for easy recycling. Then, the pusher unit 5 operates, pushing the residual material roll towards the open end of the winding bar 2 until the residual material roll is detached from the winding bar 2, realizing the unloading of the residual material roll, thereby replacing manual operation and completing the recycling and rolling of the residual material.

[0030] Specifically, the pushing unit 5 includes a pushing plate 51 and a pushing cylinder 52. The pushing cylinder 52 is fixed on one side end face of the disc base 4, and the telescopic end of the pushing cylinder 52 extends through to the other side of the disc base 4. The pushing plate 51 is fixed by a connecting rod 53. This design allows the pushing cylinder 52, the connecting rod 53, and the pushing plate 51 to rotate synchronously with the disc base 4. The pushing cylinder 52 can be a linear drive structure such as a pneumatic cylinder, a hydraulic cylinder, or an electric pushing cylinder. In this application, the pushing cylinder 52 is preferably an electric pushing cylinder, which is powered by a sliding contact ring to adapt to the position change when it rotates with the disc base 4.

[0031] Secondly, the push plate 51 is mounted on the outer wall of the take-up bar 2, allowing the push plate 51 to be adjusted and moved along the length of the take-up bar 2.

[0032] When rewinding the remaining material, the pusher cylinder 52 retracts, driving the pusher plate 51 to move close to the disc seat 4. When pushing the material, the pusher cylinder 52 extends, and under the fixed connection of the connecting rod 53, it pushes the pusher plate 51 to the open end of the winding rod 2. The pusher plate 51 fits tightly against the outer wall of the winding rod 2, which can push the remaining material rolled on the winding rod 2 to the open end of the winding rod 2 until the remaining material is pushed away from the winding rod 2.

[0033] Specifically, the drive unit 6 includes a drive motor 62, a main gear 63, and a gear ring 64. A shaft 61 is coaxially fixed on the side of the disc seat 4 away from the winding bar 2. The gear ring 64 is fixed on the shaft 61. The drive motor 62 is fixed on the side of the U-shaped seat 3 away from the disc seat 4. The main gear 63 is fixed on the output shaft of the drive motor 62 and meshes with the gear ring 64.

[0034] The drive motor 62 operates, and its output shaft can drive the main gear 63 to rotate. The rotating main gear 63 can mesh with the drive gear ring 64 and drive the shaft 61 to rotate. In turn, the shaft 61 can drive the disc seat 4 to rotate synchronously, providing effective drive for the rotation of the disc seat 4 and the winding bar 2.

[0035] In addition, to avoid the toothed ring 64 obstructing the rotation of the pusher cylinder 52, the application makes the following design: the distance between the toothed ring 64 and the disc seat 4 is greater than the length of the cylinder body of the pusher cylinder 52, thereby avoiding motion interference between the pusher cylinder 52 and the toothed ring 64; in addition, the same problem can also be solved by designing that the distance between the point on which the pusher cylinder 52 is installed on the disc seat 4 and the axis of the disc seat 4 is greater than the radius of the toothed ring 64.

[0036] Example 2

[0037] Please see Figure 1 and Figure 3 The difference between this embodiment and Embodiment 1 is that:

[0038] A vertical plate 11 is fixed on one side of the frame plate 1. A guide rod 12 extending along the length of the frame plate 1 is fixed on the vertical plate 11. Sliding seats 31 are fixed on the top of both sides of the U-shaped seat 3. Both sliding seats 31 are slidably fitted onto the guide rod 12. This design allows the U-shaped seat 3 and its components to have the ability to be adjusted relative to the frame plate 1.

[0039] A threaded rod 7 is rotatably mounted through the side of the U-shaped seat 3 away from the disc seat 4. The threaded rod 7 is coaxially fixed with the shaft 61. A threaded hole 71 is provided on the vertical plate 11, and the threaded rod 7 is threadedly matched and installed in the threaded hole 71.

[0040] When the shaft 61 rotates, it can synchronously drive the threaded rod 7 to rotate. Under the threaded engagement of the threaded rod 7 and the threaded hole 71, it can drive the U-shaped seat 3 and its components to slide and adjust along the guide rod 12. This translation adjustment mechanism can make the winding rod 2 adjust the position of the remaining material winding in coordination with the winding rotation, ensuring that the remaining material is evenly wound on the winding rod 2.

[0041] Meanwhile, the translational adjustment of the U-shaped seat 3 and its attached components depends on the threaded engagement of the threaded rod 7 and the threaded hole 71. The power for the rotation of the threaded rod 7 comes from its fixation with the shaft 61, thus eliminating the need for an additional drive for the threaded rod 7, reducing drive costs. At the same time, it allows the winding of the excess material and the adjustment of the winding point offset to be carried out simultaneously, with a high degree of timing coordination.

[0042] In addition, an anti-disengagement cap (not marked in the figure) is installed at the end of the threaded rod 7 away from the shaft 61. The diameter of the anti-disengagement cap is larger than the inner diameter of the threaded hole 71. The anti-disengagement cap and the vertical plate 11 form a blocking fit, which can prevent the U-shaped seat 3 from moving excessively and causing the threaded rod 7 to come out of the threaded hole 71.

[0043] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
