Description

Technical Field

[0001] This utility model relates to the field of steel wire pre-bending technology, and in particular to a steel wire pre-bending device for producing coil nails. Background Technology

[0002] Coil nails are typically wound in coils on a nail reel for continuous nail supply in automated nailing equipment. The steel wire itself is straight; without pre-bending, direct coiling would result in excessive rigidity and significant internal stress, causing the coil nails to loosen during storage or use and fail to maintain their coiled shape. Pre-bending allows the steel wire to adapt to a bent state beforehand, reducing internal stress and making the coil nails tighter and more stable after coiling.

[0003] Existing pre-bending equipment is difficult to adjust the bending angle of the steel wire during use, and requires a long time and multiple processes to move and bend the steel wire, resulting in low work efficiency. Therefore, we propose a pre-bending device for steel wire in coil nail production. Utility Model Content

[0027] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings;

[0028] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] refer to Figure 1-4 A wire pre-bending device for producing coil nails includes a fixed frame 3, a first electric telescopic rod 4 is fixedly installed on the bottom inner wall of the fixed frame 3, a pre-bending guide frame 5 is fixedly installed on the output end of the first electric telescopic rod 4, and a wire pre-bending angle adjustment component 1 is provided on the pre-bending guide frame 5.

[0030] The wire pre-bending angle adjustment assembly 1 includes a fixed plate 11, a motor 12, a drive shaft 13, a movable shaft 14, an auxiliary shaft 15, and a pre-bending angle adjustment plate 17. The fixed plate 11 is fixedly installed on the front and rear sides of the pre-bending guide frame 5. The motor 12 is fixedly installed on the front side of the fixed plate 11. The drive shaft 13 is fixedly installed on the output end of the motor 12. The movable shaft 14 is rotatably installed on the inner side of the fixed plate 11. The auxiliary shaft 15 is rotatably installed on the inner side of the pre-bending guide frame 5. The pre-bending angle adjustment plate 17 is rotatably installed on the outer side of the drive shaft 13 and the movable shaft 14, respectively.

[0031] In this embodiment, a guide groove 6 is provided on the top of the fixed frame 3, and a wire pre-bending limiting and fixing component 2 is provided on the fixed frame 3 and the guide groove 6.

[0032] In this embodiment, the wire pre-bending angle adjustment assembly 1 also includes a bevel gear 16 and a wire guide placement groove 18. The bevel gear 16 is fixedly installed on the outside of the drive shaft 13, the movable shaft 14 and the auxiliary shaft 15 respectively. Adjacent bevel gears 16 mesh with each other. Multiple wire guide placement grooves 18 are opened on the top of the pre-bending guide frame 5 and the pre-bending angle adjustment plate 17.

[0033] In this embodiment, the wire pre-bending limiting and fixing assembly 2 includes an installation groove 21, a ball bearing 22, a limiting slider 23, and a fixing frame 24. The installation groove 21 is formed on the bottom inner wall of the guide slide 6. The ball bearing 22 is rotatably installed on the inner side of the installation groove 21. The limiting slider 23 is slidably installed on the inner side of the guide slide 6, and the limiting slider 23 abuts against the ball bearing 22. The fixing frame 24 is fixedly installed on the top of the fixing frame 3 and the limiting slider 23.

[0034] In this embodiment, the wire pre-bending limiting and fixing assembly 2 also includes a second electric telescopic rod 25, a wire pressing fixing plate 26, and an anti-slip pad 27. The second electric telescopic rod 25 is fixedly installed on the top of the fixing frame 24, the wire pressing fixing plate 26 is fixedly installed on the output end of the second electric telescopic rod 25, and the anti-slip pad 27 is fixedly installed on the bottom of the wire pressing fixing plate 26 and the top of the fixing frame 3 and the limiting slider 23.

[0035] In this embodiment, the wire pre-bending limiting and fixing assembly 2 also includes a fixing seat 28, a guide shaft 29, and a wire guide groove 30. The fixing seat 28 is fixedly installed on the top of the fixing frame 3, the guide shaft 29 is rotatably installed on the inner side of the fixing seat 28, and multiple wire guide grooves 30 are opened on the outer side of the guide shaft 29. The U-shaped fixing frame 24 and the wire pressing fixing plate 26 form an upper and lower clamping structure, and the bottom anti-slip pad 27 increases the friction to prevent the wire from slipping and deviating during the pre-bending process. The wire guide groove 30 of the guide shaft 29 and the wire guide placement groove 18 of the pre-bending guide frame 5 limit the wire in multiple segments to ensure the accuracy of the bending point. Compared with the single-point fixing method of traditional equipment, multi-point collaborative limiting improves the consistency of the pre-bending size.

[0036] In this embodiment, the guide chute 6 and the limiting slider 23 are both T-shaped, and the fixing frame 24 is U-shaped. The device is automatically driven by an electric telescopic rod and a motor, eliminating the need for manual bending. The pre-bending angle can be precisely controlled by the motor speed. With the adaptive adjustment of the guide structure, the operator only needs to complete the wire feeding to start the entire pre-bending process, greatly reducing manual intervention. In addition, the combination of the T-shaped guide chute and the limiting slider makes the equipment easy to disassemble and maintain, and shortens the replacement time of parts.

[0037] In this embodiment, the pre-bending guide frame 5 is arc-shaped, and a rotating groove is provided on one side of each of the two pre-bending angle adjustment plates 17. The drive shaft 13 and the movable shaft 14 are respectively engaged with the corresponding rotating grooves. The wire pre-bending angle adjustment assembly 1 drives the shaft 13 to rotate through the motor 12. With the transmission of the bevel gear 16 and the auxiliary shaft 15, the movable shaft 14 is driven to rotate synchronously, so that the pre-bending angle adjustment plates 17 on the outside of the drive shaft 13 and the movable shaft 14 can be adjusted at multiple angles. The arc-shaped pre-bending guide frame 5 and the angle-adjustable adjustment plate work together to accurately control the bending arc of the wire, solve the problem that the angle of the traditional equipment is fixed and cannot adapt to the production needs of different specifications of coil nails, and meet the pre-bending requirements of wires of different diameters.

[0038] Specifically, the wire pre-bending angle adjustment component 1 is driven by the motor 12 to rotate the shaft 13. This, combined with the transmission of the bevel gear 16 and the auxiliary shaft 15, drives the movable shaft 14 to rotate synchronously, allowing the pre-bending angle adjustment plate 17 on the outer side of the drive shaft 13 and the movable shaft 14 to achieve multi-angle adjustment. The arc-shaped pre-bending guide frame 5, working in conjunction with the angle-adjustable adjustment plate, can precisely control the bending arc of the wire, solving the problem of fixed angles in traditional equipment and its inability to adapt to the production needs of different specifications of coil nails, thus meeting the pre-bending requirements of wires of different diameters. The device integrates wire fixing, angle adjustment, and pre-bending forming processes into one unit: the second electric telescopic rod 25 drives the wire to press down the fixing plate 26 to quickly complete the fixing of both ends of the wire; the first electric telescopic rod 4 drives the pre-bending guide frame 5 to rise, cooperating with the rotation of the pre-bending angle adjustment plate 17 to achieve synchronous pre-bending, eliminating the need for separate steps; the T-shaped limit slider 23 slides within the guide groove 6, with the ball bearing 22 assisting in reducing friction, and can synchronously adjust the wire position during the pre-bending process, eliminating the multiple positioning steps of traditional equipment and improving overall pre-bending efficiency.

[0039] The U-shaped fixing frame 24 and the wire pressing fixing plate 26 form an upper and lower clamping structure. The bottom anti-slip pad 27 increases friction and prevents the wire from slipping and shifting during pre-bending. The wire guide groove 30 of the guide shaft 29 and the wire guide placement groove 18 of the pre-bending guide frame 5 limit the wire in multiple segments to ensure accurate bending points. Compared with the single-point fixing method of traditional equipment, multi-point collaborative limiting improves the consistency of pre-bending dimensions. The device achieves automated drive through electric telescopic rods and motors, eliminating the need for manual bending. The pre-bending angle can be precisely controlled by the motor speed. With the adaptive adjustment of the guide structure, the operator only needs to complete the wire feeding to start the entire pre-bending process, greatly reducing manual intervention. In addition, the cooperation between the T-shaped guide slide and the limiting slider makes the equipment easy to disassemble and maintain, and shortens the replacement time of parts.

[0040] The rotating groove of the pre-bending angle adjustment plate 17 is designed to fit the drive shaft 13 and the movable shaft 14, reducing mechanical wear during rotation; the bevel gear 16 transmission structure has a strong load-bearing capacity and can adapt to high-intensity continuous production; the anti-slip pad 27 is made of wear-resistant rubber material, reducing the frequency of consumable replacement.

[0041] It should be noted that although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
