Description

Technical Field

[0001] This utility model relates to the technical field of copper-clad steel wire processing equipment, and in particular to a copper-clad steel wire tensioning device. Background Technology

[0002] Copper-clad steel wire is a new type of composite wire. It is made of low-carbon steel core wire, coated with copper layer and then hot-dip in lead-free tin-based alloy. It combines the high conductivity of copper wire and the high strength of steel, while also having the thermal conductivity, corrosion resistance and excellent solderability of tin. Copper-clad steel wire is widely used in electronic component leads, PCB jumpers, electronic pins and other fields.

[0003] For example, the technical key points of the tin-plated copper-clad steel wire tensioning device disclosed in our patent CN221318753U are as follows: it includes support legs, a worktable, a rectangular groove, a tensioning component, toothed plates, fixed blocks, a slide groove, a fixed frame, guide rollers, a first vertical plate, and a second vertical plate. Lifting units are provided on the opposite surfaces of the two first vertical plates and the second vertical plate. The opposite surfaces of the two first vertical plates and the second vertical plate are slidably connected to the two ends of the corresponding two guide rollers through the lifting units. A tensioning drive unit is provided on the inner wall of the rectangular groove. This invention, by rotating the handle, can drive the rotation of the rotating shaft. The rotation of the rotating shaft can drive the rotation of the gears. The rotation of the gears can drive the two toothed plates to move in opposite directions, achieving synchronous up-and-down movement of the two gears, which in turn drives the two fixed frames and the two guide rollers to move in opposite directions, thereby adjusting the copper-clad steel wire overlapping on its surface.

[0004] In the aforementioned prior art, the tensioning operation of copper-clad steel wire is carried out by manually rotating the handle to drive the tensioning assembly. Due to the long-term manual rotation of the handle, the time and energy of the workers are greatly wasted, and the workers' hands are also very likely to be injured due to prolonged work.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1-5 This utility model provides a copper-clad steel wire tensioning device, including a workbench 1, a tensioning component 2 on the workbench 1, a rectangular groove in the middle of the workbench 1, a drive box 4 fixedly connected to the surface of the workbench 1, a rotating shaft 5 penetrating the rectangular groove in the inner cavity of the drive box 4, a drive gear 3 for driving the tensioning component 2 at one end of the rotating shaft 5, a connecting shaft 6 for limiting and sliding connection at the other end of the rotating shaft 5, a bearing 7 on the outer contour of the connecting shaft 6, a support plate 8 on the outer contour of the bearing 7, a driven gear 9 on the outer contour of the connecting shaft 6, an adjusting component for sliding the support plate 8 on the top of the drive box 4, an automatic drive mechanism on one side of the drive box 4, and a manual drive mechanism on the other side of the drive box 4.

[0029] When tensioning of copper-clad steel wire is required, the automatic drive mechanism inside the drive box 4 is activated, which drives the driven gear 9 to rotate. The driven gear 9 drives the connecting shaft 6 to rotate, which in turn drives the rotating shaft 5 and the drive gear 3 to rotate. The rotating drive gear 3 drives the tensioning assembly 2 on the worktable 1 to perform tensioning of the copper-clad steel wire. If the automatic drive mechanism fails, the connecting shaft 6 can be moved out of the rotating shaft 5 using the adjusting component, so that the driven gear 9 on the connecting shaft 6 can be moved to the manual drive mechanism. This allows the operator to operate the equipment in an emergency if the servo motor 10 fails, increasing the equipment's practicality.

[0030] The automatic drive mechanism includes a servo motor 10 fixedly connected to the inner wall of the drive box 4. The end of the servo motor 10 is keyed to a motor shaft 11. The outer contour of the motor shaft 11 is provided with a drive gear 12 that meshes with the driven gear 9. The outer contour of the connecting shaft 6 is fixedly connected with connecting rods 16 arranged in a circular array. The inner wall of the rotating shaft 5 is provided with a locking groove 17 for the connecting rods 16 to be engaged.

[0031] By starting the servo motor 10, the driving gear 12 on the motor shaft 11 is rotated, which in turn drives the driven gear 9 to rotate. When the driven gear 9 rotates, it drives the connecting shaft 6 to rotate. The bearing 7 and the support plate 8 provide support when the connecting shaft 6 rotates. When the connecting shaft 6 rotates, the connecting rod 16 on the connecting shaft 6 engages with the locking groove 17 opened in the inner wall of the rotating shaft 5, which causes the rotating shaft 5 to rotate. The rotating shaft 5 drives the drive gear 3 to rotate, which drives the tensioning assembly 2 to perform tensioning operations on the copper-clad steel wire. This increases the tensioning efficiency of the equipment on the copper-clad steel wire and reduces the labor intensity of the workers.

[0032] The top of the drive box 4 has a slot, and a top plate 41 is installed in the slot. An adjusting component is installed on the top of the top plate 41. The adjusting component includes a telescopic rod 13 fixedly connected to the top of the support plate 8. The top of the top plate 41 has a sliding groove 14 for the telescopic rod 13 to slide. A handle 15 is fixedly connected to the top of the telescopic rod 13. A limit groove 21 is symmetrically opened on the top of the drive box 4 with the sliding groove 14 as the center line. A locking rod that engages with the connecting rod 16 is fixedly connected to the bottom of the handle 15. The manual drive mechanism includes a movable shaft 18 rotatably connected to the drive box 4. A throttle 19 is fixedly connected to one end of the movable shaft 18. A driving gear 20 that meshes with the driven gear 9 is fixedly connected to the other side of the movable shaft 18.

[0033] After the servo motor 10 is damaged, lifting the handle 15 causes the telescopic rod 13 to move upward, causing the locking rod on the handle 15 to move out of the limiting groove 21. Then, moving the handle 15 causes the telescopic rod 13 to move within the sliding groove 14, thereby causing the support plate 8 to move towards the second drive gear 20. The moving support plate 8 causes the connecting shaft 6 on the inner wall of the bearing 7 to move out of the rotating shaft 5, so that the driven gear 9 on the connecting shaft 6 meshes with the second drive gear 20. Subsequently, the operator turns the throttle 19 to drive the movable shaft 1. The rotation of the second drive gear 20 on the 8 drives the rotation of the connecting shaft 6. Because the connecting rod 16 on the connecting shaft 6 engages with the slot 17 on the inner wall of the rotating shaft 5, the rotation of the connecting shaft 6 drives the rotating shaft 5 to rotate. The rotating shaft 5 then drives the drive gear 3 to rotate, which in turn drives the tensioning assembly 2 to tension the copper-clad steel wire. Furthermore, if any parts inside the drive box 4 are damaged, the operator can remove the drive box 4 from the slot and then repair or replace the damaged parts, further increasing the practicality of the equipment.

[0034] Working principle: The servo motor 10 is started to drive the drive gear 12 on the motor shaft 11 to rotate, which in turn drives the driven gear 9 to rotate. When the driven gear 9 rotates, it drives the connecting shaft 6 to rotate. The bearing 7 and the support plate 8 support the connecting shaft 6 as it rotates. When the connecting shaft 6 rotates, the connecting rod 16 on the connecting shaft 6 engages with the locking groove 17 on the inner wall of the rotating shaft 5, which causes the rotating shaft 5 to rotate. The rotating shaft 5 drives the drive gear 3 to rotate, which drives the tensioning assembly 2 to perform tensioning operations on the copper-clad steel wire.

[0035] After the servo motor 10 is damaged, the handle 15 is lifted upwards to move the telescopic rod 13 upwards, causing the locking rod on the handle 15 to move out of the limiting groove 21. Then, the handle 15 is moved to move the telescopic rod 13 in the sliding groove 14, thereby moving the support plate 8 towards the second drive gear 20. The moving support plate 8 causes the connecting shaft 6 on the inner wall of the bearing 7 to move out of the rotating shaft 5, so that the driven gear 9 on the connecting shaft 6 meshes with the second drive gear 20. Then, the operator turns the throttle 19 to drive the second drive gear 20 on the movable shaft 18 to rotate, which in turn drives the connecting shaft 6 to rotate. Because the connecting rod 16 on the connecting shaft 6 is engaged with the locking groove 17 on the inner wall of the rotating shaft 5, the rotation of the connecting shaft 6 drives the rotation of the rotating shaft 5 to rotate. The rotating shaft 5 drives the drive gear 3 to rotate, driving the tensioning assembly 2 to perform tensioning operations on the copper-clad steel wire.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
