Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and more specifically, it relates to a steel wire feeding device for screw manufacturing. Background Technology

[0002] In the steel wire processing of screw manufacturing, the uncoiling and feeding device is a crucial link connecting raw materials and processing equipment. Its stability directly affects the efficiency and finished product quality of subsequent processes such as cold heading and wire rolling. Existing steel wire feeding devices typically rely on radially distributed positioning rods to fix the inner coil of the wire coil, preventing the coil from shifting or shaking during uncoiling. However, the current positioning rod adjustment method has significant limitations: each positioning rod must be operated independently. Adjustment requires loosening the locking bolts one by one, manually moving it to its approximate position, and then tightening them one by one. The entire process requires repeated confirmation of the consistency of the positions of each positioning rod. This operation is not only cumbersome and time-consuming, but also particularly problematic when changing wire coils with different inner coil diameters, often requiring a considerable amount of time for a single change, severely slowing down the production pace and resulting in poor overall performance. Therefore, this utility model proposes a steel wire feeding device for screw manufacturing. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a feeding device for steel wire used in screw manufacturing. This feeding device is characterized by convenient adjustment and simple operation.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: This utility model relates to a steel wire feeding device for screw manufacturing, comprising a base, a central column erected on the base, a shaft assembly rotatably connected to the central column, and at least three upper and lower crossbars arranged in a circular array around an axis on the shaft assembly. Both the lower and upper crossbars extend radially along the shaft assembly. An upper sleeve is slidably connected to the upper crossbar, and a lower sleeve is slidably connected to the lower crossbar. An adjusting rod connects the lower sleeve and the upper sleeve. The upper sleeve is provided with an upwardly extending guide rod. The shaft assembly has a movable disc arranged upwards and a fixed disc arranged downwards. The movable disc has curved adjustment holes that match the adjustment rods one by one. One end of the curved adjustment hole is close to the edge of the movable disc and the other end is close to the axis of the movable disc. The adjustment rod is slidably connected in the curved adjustment hole. The movable disc has a number of adjacent positioning grooves with equal included angles around the end facing the fixed disc. The fixed disc has ball-head plungers that match the positioning grooves one by one. The ball head of the ball-head plunger is embedded in the positioning groove.

[0005] The present invention is further configured such that: a hand-holding ring is provided outside the movable disc, and a plurality of spokes are arranged around the hand-holding ring and the movable disc, with one end connected to the movable disc and the other end connected to the hand-holding ring.

[0006] The present invention is further configured such that the bottom of the fixed disc is provided with a handle that extends downward.

[0007] The present invention is further configured such that a vertical rod is connected in series between the end of the upper crossbar that is not connected to the shaft assembly and the end of the lower crossbar that is not connected to the shaft assembly.

[0008] The present invention is further configured such that the included angle between two adjacent upper crossbars is equal; each lower crossbar is located directly below the corresponding upper crossbar.

[0009] In summary, the present invention has the following beneficial effects: The steel wire feeding device for screw manufacturing involved in the present invention, through the linkage between the movable disc and the curved adjustment hole, only needs to rotate relative to the fixed disc to drive all positioning rods to slide synchronously in the radial direction, completing the position adjustment in one go. This eliminates the repetitive operation of loosening, moving, and locking one by one in the traditional method, greatly shortening the adjustment time, improving the adjustment efficiency, effectively ensuring the continuity of production, and having complete overall functions and strong practicality.

However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0012] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0013] Example 1 See Figure 1 and Figure 2As shown, the screw manufacturing steel wire feeding device of this embodiment includes a base 1, a central column 2 vertically mounted on the base 1, and a shaft assembly 3 rotatably connected to the central column 2. The shaft assembly 3 has four upper crossbars 4 and lower crossbars 5 arranged in a circular array at equal intervals around its axis. Both the lower crossbars 5 and the upper crossbars 4 extend radially along the shaft assembly 3. Each lower crossbar 5 is located directly below a corresponding upper crossbar 4. An upper sleeve 6 is slidably connected to the upper crossbar 4, and a lower sleeve 7 is slidably connected to the lower crossbar 5. An adjusting rod 8 connects the lower sleeve 7 and the upper sleeve 6. The upper sleeve 6 has an upwardly extending positioning rod 9. The shaft assembly 3 is rotatably connected to a movable disc 10 arranged above and a fixed disc 11 arranged below. The movable disc 10 has curved adjustment holes 12 that match the adjustment rods. One end of the curved adjustment hole 12 is close to the edge of the movable disc and the other end is close to the axis of the movable disc. The adjustment rod 8 is slidably connected in the curved adjustment hole 12. The movable disc 10 has a number of adjacent positioning grooves (not shown) with equal included angles around the end facing the fixed disc. The fixed disc 11 has ball-head plungers (not shown) that match the positioning grooves. The ball head of the ball-head plunger is embedded in the positioning groove.

[0014] In this embodiment, one hand holds the fixed disc 11 and the other hand holds the movable disc 10. The movable disc 10 is rotated clockwise relative to the fixed disc 11. During the rotation, the adjusting rod 8 moves outward within the corresponding curved adjusting hole 12, causing all upper sleeves 6 to slide axially relative to the upper crossbar 4 and all lower sleeves 7 to slide axially relative to the lower crossbar 5, resulting in all positioning rods 9 being adjusted axially outward in sync. Alternatively, one hand holds the fixed disc 11 and the other hand holds the movable disc 10. The movable disc 10 is rotated counterclockwise relative to the fixed disc 11. During the rotation, the adjusting rod 8 moves inward within the corresponding curved adjusting hole 12, causing all upper sleeves 6 to slide axially relative to the upper crossbar 4 and all lower sleeves 7 to slide axially relative to the lower crossbar 5, resulting in all positioning rods 9 being adjusted axially inward in sync.

[0015] The positioning groove, in conjunction with the ball-head plunger, serves to lock the position of the movable disc 10 after its circumferential position has been adjusted.

[0017] Furthermore, the bottom of the fixed disc 11 is provided with a handle 15 that extends downward.

[0018] In this embodiment, both the hand ring 13 and the handle 15 are designed for easy gripping.

[0019] Example 3 See Figure 1 and Figure 2 As shown, the screw manufacturing steel wire feeding device involved in this embodiment is further configured, based on embodiment 1, with a vertical rod 16 connected in series between the end of the upper crossbar 4 that is not connected to the shaft assembly and the end of the lower crossbar 5 that is not connected to the shaft assembly.

[0020] In this embodiment, the vertical rod 16 is used to connect the upper horizontal rod 4 and the lower horizontal rod 5, thereby enhancing the structural strength.

[0021] The screw manufacturing steel wire feeding device involved in this utility model, through the linkage between the movable disc and the curved adjustment hole, only needs to rotate relative to the fixed disc to drive all positioning rods to slide synchronously in the radial direction, completing the position adjustment in one go.
