[0001] The utility model belongs to the technical field of spring production, in particular to a winding device for spring production. Background Art

[0002] The winding device for spring production is a device used to wind metal wire or steel bar into a spring shape when producing springs. Its principle is to drive the winding shaft through the transmission device to make it rotate, and guide the metal wire or strip to the winding shaft through the guide device. After rotation and tension adjustment, the metal wire or strip is wound into a spring shape.

[0003] In the prior art, for example, a steel bar winding device for spring production provided by Chinese patent publication number CN217398071U rotates relative to a reel through a base, and after the steel bar comes out of the steel bar drawing device, it enters between the L-shaped member and the support member along the guide rail, and the steel bar is gradually curled and supported on the inner side of the L-shaped member. In this way, the steel bar can be rolled from bottom to top during the winding process, avoiding the phenomenon of steel bar winding when rolling from inside to outside. However, the above technical solution still has the following problems:

[0004] The applicant believes that as the steel bars are rolled into the space between the support and the L-shaped member, the height of the steel bars rolled into the L-shaped member gradually increases, resulting in the L-shaped member easily interfering with the steel bars when the steel bars are rolled from the external guide rail onto the L-shaped member, and the steel bars are easily entangled on the L-shaped member, affecting the effect of the steel bar rolling. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a spring production winding device, which solves the problem that as the height of the steel bar rolled into the L-shaped piece gradually increases, the L-shaped piece easily interferes with the steel bar.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the utility model, a winding device for spring production is proposed, including a cylinder, a turntable is rotatably arranged in the middle part of the cylinder, the turntable rotates relative to the cylinder, a plurality of support rods are fixedly connected to the turntable on the side facing the inside of the cylinder, the end of the support rod away from the turntable is rotatably connected to an adjusting rod, a guide ball is movably installed on the end of the adjusting rod away from the support rod, a winding opening is opened at the top of the cylinder, and an arc segment for guiding the guide ball is arranged on the cylinder at the winding opening.

[0007] Preferably, a column is fixedly connected to the outside of the cylinder.

[0008] Preferably, a middle portion of the turntable is rotatably connected to a support leg.

[0009] Preferably, a gear ring is fixedly mounted on the outer side of the turntable.

[0010] Preferably, a retaining ring is fixedly mounted on the top end of the cylinder by bolts.

[0011] Preferably, the retaining ring is provided with a winding opening and an arc segment which are equivalent to those of the cylinder.

[0012] Preferably, a first sliding groove is opened inside the support rod, a connecting rod is rotatably connected to one side of the adjustment rod, a first sliding groove and a second sliding groove are opened on the side walls of the support rod and the connecting rod respectively, and the same sliding column is slidably connected in the first sliding groove and the second sliding groove located on the same side.

[0013] Preferably, a limiting shell is fixedly connected to the middle of the rotating disk, and a leaf spring is arranged on one side of the limiting shell facing the corresponding connecting rod.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By setting a cylinder, an arc segment and an adjusting rod, a flange is set on the top of the cylinder, and a guide ball is movably installed on the end of the adjusting rod. The guide ball is located between the cylinder and the retaining ring and moves back and forth, prompting the adjusting rod and the support rod to rotate relative to each other. The steel bar enters the cylinder from the winding port, effectively avoiding the interference between the steel bar and the support rod after the steel bar extends from the winding port. The steel bar is located in the cylinder when it is wound to avoid causing harm to people. The guiding effect of the connecting rod on the steel bar prompts the steel bar to be wound from the bottom end of the support rod.

[0020] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 and Figure 3 As shown, a winding device for spring production includes a cylinder 1, a turntable 9 is rotatably provided in the middle of the cylinder 1, the turntable 9 rotates relative to the cylinder 1, a support rod 7 is fixedly connected to the side of the turntable 9 facing the inside of the cylinder 1, a plurality of support rods 7 are evenly distributed about the axis of the turntable 9, an adjusting rod 6 is rotatably connected to the end of the support rod 7 away from the turntable 9, a guide ball 12 is movably installed on the end of the adjusting rod 6 away from the support rod 7, a winding port 4 is opened at the top of the cylinder 1, and an arc segment 5 is provided at the winding port 4 of the cylinder 1. When external steel bars extend into the cylinder 1 through the winding port 4, The support rod 7 is driven to rotate by rotating the turntable 9, and the support rod 7 drives the adjusting rod 6 and the guide ball 12 to rotate after the rotation. The steel bar passes through the winding mouth 4 and is wound along with the support rod 7. The guide ball 12 is in contact with the flange part of the top of the cylinder 1. When the guide ball 12 moves to the arc segment 5, the arc segment 5 guides the guide ball 12, prompting the adjusting rod 6 and the support rod 7 to rotate relative to each other, effectively avoiding the interference between the steel bar and the support rod 7 after the steel bar extends from the winding mouth 4. At the same time, when the steel bar is wound onto the support rod 7, since the steel bar is located in the cylinder 1 when it is wound, the steel bar will not cause harm to people outside.

[0022] As an implementation method in this embodiment, Figure 1 and Figure 2 As shown, the outside of the cylinder 1 is fixedly connected with a column 2, and the column 2 is used to support the cylinder 1. The middle part of the turntable 9 is rotatably connected with a support leg 10, and a bearing is arranged between the support leg 10 and the turntable 9 to reduce friction. A gear ring 11 is fixedly installed on the outside of the turntable 9, and the gear ring 11 is used to cooperate with an external motor and gears. The turntable 9 is driven to rotate through the gear ring 11, and the turntable 9 drives the spring steel bar to be wound through the support rod 7.

[0023] As an implementation method in this embodiment, Figure 1 and Figure 3As shown, a retaining ring 3 is fixedly installed on the top of the cylinder 1, and the retaining ring 3 is detachably connected to the cylinder 1 by bolts. A winding opening 4 and an arc segment 5 are opened on one side of the retaining ring 3. The winding opening 4 opened on the cylinder 1 and the retaining ring 3 have the same shape and size, and the arc segment 5 set on the cylinder 1 and the retaining ring 3 have the same shape and size. The guide ball 12 is located between the cylinder 1 and the retaining ring 3. The retaining ring 3 is used to prevent the guide ball 12 from flipping over excessively to avoid contact with the top of the cylinder 1. The steel bar of the spring passes through the retaining ring 3 and the cylinder 1 through the winding opening 4 and is rolled onto the support rod 7.

[0024] As an implementation method in this embodiment, Figure 1 and Figure 3 As shown, a first slide groove 14 is provided inside the support rod 7, and a connecting rod 15 is rotatably connected to one side of the adjusting rod 6. The side walls of the support rod 7 and the connecting rod 15 are respectively provided with a first slide groove 14 and a second slide groove 16. The first slide groove 14 and the second slide groove 16 on the same side are slidably connected with the same sliding column 17. When the steel bar is rolled into the outer wall of the support rod 7, the steel bar will squeeze the connecting rod 15, causing the bottom end of the connecting rod 15 to penetrate the support rod 7 and gradually deviate outward. The connecting rod 15 also guides the steel bar, causing the steel bar to be rolled up from the bottom end of the support rod 7. In order to improve the guiding effect of the connecting rod 15 on the steel bars, the middle part of the turntable 9 is fixedly connected to the limit shell 8, and the limit shell 8 is provided with a leaf spring 13 on the side facing the corresponding connecting rod 15. The leaf spring 13 is located in the groove opened in the limit shell 8 and is fixed to the limit shell 8. As the connecting rod 15 is squeezed by the steel bars and tilted upward, the connecting rod 15 and the leaf spring 13 conflict with each other, and the leaf spring 13 conflicts with the surface of the connecting rod 15 through its own elastic force, causing the bottom end of the connecting rod 15 to tilt downward, further guiding the steel bars during winding, so that the steel bars start to be wound from the bottom end of the support rod 7.

[0025] The working principle of the utility model is as follows: when in use, firstly, the external steel bar is extended from the winding port 4, and the turntable 9 is driven to rotate through the gear ring 11 by the external motor and gear, and the turntable 9 drives the steel bar extended into the winding port 4 to be wound through the support rod 7, and the steel bar squeezes the connecting rod 15, prompting the bottom end of the connecting rod 15 to penetrate the support rod 7 and gradually deviate outward, and the connecting rod 15 and the leaf spring 13 conflict with each other, and the leaf spring 13 conflicts with the surface of the connecting rod 15 through its own elastic force, prompting the bottom end of the connecting rod 15 to tilt downward, further guiding the steel bar during winding, so that the steel bar starts to be wound from the bottom end of the support rod 7, prompting the steel bar to be arranged neatly on the support rod 7, and reducing the spacing; the guide ball 12 is located between the cylinder 1 and the retaining ring 3 and moves back and forth, and the arc segment 5 guides the guide ball 12, prompting the adjusting rod 6 and the support rod 7 to rotate relative to each other, effectively avoiding the interference between the steel bar and the support rod 7 after the steel bar is extended from the winding port 4, and the steel bar is located in the cylinder 1 when winding, so as to avoid causing harm to people.

[0026] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
