Description

Technical Field

[0001] This application relates to the field of rope processing equipment, and in particular to a metal wire cutting and binding mechanism. Background Technology

[0002] In existing industrial production processes, securing the ends of flexible materials such as ropes and cables with metal wire is a core step in ensuring the reliability of bundling. Traditional operations generally employ a manual bending and securing method: the operator must cut the metal wire, manually bend it into a U-shape, perform a secondary bend to close the loop, and then wrap and bundle the rope. This method has significant drawbacks in practical applications:

[0003] During manual operation, a single cycle of bending the metal wire and binding the rope end takes 5-8 seconds, and the operator's physical limitations make it difficult to maintain a high-frequency operation. In industrial continuous production scenarios, this mode severely restricts the overall production line cycle time, resulting in a unit-time capacity density that is less than 30% of the standard operating level of automated equipment.

[0004] While some semi-automatic locking devices are attempting to replace manual labor, most employ a split design—the wire cutting module and bending mechanism are separate, still requiring manual intervention to complete the final rope winding process. This not only extends the gap between processes by 15%-20%, but also makes it easier for wire displacement and misalignment to occur during the mechanism's coordination. Utility Model Content

[0005] The purpose of this application is to provide an integrated, fully automated metal wire processing device that achieves a metal wire cutting and binding mechanism with efficient cutting, precise bending, and automatic binding functions through structural innovation.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A metal wire cutting and binding mechanism includes a left binding device, a right cutting and binding device, and a second guide assembly. The left binding device and the right cutting and binding device are disposed opposite to each other on the guide assembly. The right cutting and binding device is used to cut the metal wire and bend it into a U-shape. The left binding device is used to bend the opening of the metal wire so that the metal wire is bound to the head of the bent rope.

[0008] In one embodiment, the right cutting and binding device includes a right moving seat, a right cutting and binding mold, a third cam drive device, and a lower ejector mold. The right moving seat is mounted on a second guide assembly. The third cam drive device can drive the right moving seat to move left and right. The right cutting and binding mold is mounted on the right moving seat. One side of the right cutting and binding mold is close to the mounting seat of the rope head bending mechanism. The mounting seat of the rope head bending mechanism is provided with a metal wire through hole. When the right cutting and binding mold cooperates with the mounting seat of the rope head bending mechanism to cut the metal wire, the right cutting and binding mold continues to move to the left and cooperates with the lower ejector mold to bend the metal wire into a U-shape.

[0009] In one embodiment, the left end of the right cutting and binding mold is provided with a first concave mold portion and a second concave mold portion, the second concave mold portion is located in the middle of the first concave mold portion, and the inner side of the first concave mold portion is provided with a first bending guide groove.

[0010] In one embodiment, the lower ejector die includes an ejector punch, a rack and pinion assembly, and a fifth cam drive device, wherein the fifth cam drive device drives the ejector punch to perform lifting and lowering movements via the rack and pinion assembly.

[0011] In one embodiment, the left rope-tying device includes a left moving seat, a left rope-tying mold, and a second cam drive device. The left rope-tying mold is mounted on the left moving seat, and the left moving seat is mounted on a second guide assembly. The second cam drive device is used to drive the left moving seat to move the left rope-tying mold left and right.

[0012] In one embodiment, a punch is provided on the right side of the left rope-binding mold, an arc-shaped groove is provided on the right side of the punch, a second bending guide groove is provided on the inner side of the arc-shaped groove, and a limiting protrusion is also provided on the right side of the left rope-binding mold. The arc-shaped groove of the left rope-binding mold cooperates with the limiting protrusion to realize the U-shaped opening of the bent metal wire, so that the metal wire is tied to the head of the bent rope.

[0013] In one embodiment, the second cam drive device includes a second follower and a second cam, the second follower being mounted on the left movable seat, and the second cam driving the left movable seat to move left and right through the second follower.

[0014] The beneficial effects of this application are as follows:

[0015] This application utilizes a symmetrical and coordinated design of a left rope-binding device and a right rope-cutting device, along with directional guidance from a second guide component, to achieve continuous automated operation of metal wire cutting, U-shaped bending, and locking. This effectively replaces the traditional step-by-step manual operation mode, significantly reducing labor intensity and human error. Furthermore, the right rope-cutting device integrates both metal wire cutting and U-shaped bending functions, while the left rope-binding device completes the locking and fastening through a specific bending action. This integrates multiple processes into a single workstation, reducing equipment footprint and the number of transmission components, and improving the reliability of the mechanism. Moreover, the cutting and bidirectional bending processes can be completed in a single operation cycle, saving approximately 40% of the process time compared to traditional multi-station sequential processing, while also reducing metal wire waste, meeting the efficiency and cost control requirements of mass industrial production.

[0023] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] like Figure 1As shown, the rope head-tying machine has an upper wire mechanism 1 located at the rear end of the metal wire cutting and binding mechanism 2, used to transport the metal wire to the metal wire cutting and binding mechanism 2. The driving device 4 drives the metal wire cutting and binding mechanism 2 to cut the metal wire and bend it into a U-shape. The rope head bending mechanism 3 is located between the upper wire mechanism 1 and the metal wire cutting and binding mechanism 2. After the metal wire is bent into a U-shape, the driving device drives the rope head bending mechanism 3 to bend the head of the rope downwards into the U-shaped opening of the metal wire. Finally, the metal wire cutting and binding mechanism 2 bends the U-shaped opening of the metal wire, allowing the metal wire to be tied to the bent head of the rope.

[0025] like Figure 2 As shown, the metal wire cutting and binding mechanism includes a left binding device 21, a right cutting and binding device 22, a second guide assembly 23, and a reset assembly 24. The left binding device 21 and the right cutting and binding device 22 are arranged opposite to each other on the guide assembly. The reset assembly 24 is arranged between the left binding device 21 and the right cutting and binding device 22 and is used to reset the left binding device 21 and the right cutting and binding device 22. The right cutting and binding device 22 is used to cut the metal wire and bend it into a U-shape. The left binding device 21 is used to bend the U-shaped opening of the metal wire so that the metal wire is tied to the head of the bent rope.

[0026] like Figure 3 As shown, the right cutting and binding device 22 includes a right moving seat 221, a right cutting and binding mold 222, a third cam drive device 223, and a lower ejector mold 224. The right moving seat 221 is mounted on the second guide assembly 23. The third cam drive device can drive the right moving seat 221 to move left and right. The right cutting and binding mold 222 is mounted on the right moving seat 221. The mounting seat of the rope head bending mechanism is provided with a metal wire through hole. One side of the right cutting and binding mold 222 is close to the mounting seat of the rope head bending mechanism. When the right cutting and binding mold 222 cooperates with the mounting seat of the rope head bending mechanism 3 to cut the metal wire, the right cutting and binding mold 222 continues to move to the left and cooperates with the lower ejector mold 224 to bend the metal wire into a U-shape.

[0027] like Figure 4 As shown, the left end of the right cutting and binding mold 222 is provided with a first die part 2221 and a second die part 2222. The second die part 2222 is located in the middle of the first die part, and the inner side of the first die part 2221 is provided with a first bending guide groove 2223.

[0028] like Figure 5 As shown, the lower ejector die 224 includes an ejector punch 2241, a rack and pinion assembly 2242, and a fifth cam drive device 2243. The fifth cam drive device 2243 drives the ejector punch 2241 to move up and down through the rack and pinion assembly 2242.

[0029] like Figure 5 As shown, the upper end of the ejector punch 2241 is cylindrical and cooperates with the second die part 2222 to bend the metal wire into a U-shape.

[0030] like Figure 6 As shown, the left rope-tying device 21 includes a left moving seat 211, a left rope-tying mold 212, and a second cam drive device 213. The left rope-tying mold 212 is mounted on the left moving seat 211, and the left moving seat 211 is mounted on the second guide assembly 23. The second cam drive device 213 is used to drive the left moving seat 211 to move the left rope-tying mold 212 left and right.

[0031] like Figure 7 As shown, a punch 2121 is provided on the right side of the left rope binding mold 212, an arc-shaped groove 2122 is provided on the right side of the punch 2121, a second bending guide groove 2123 is provided on the inner side of the arc-shaped groove 2122, and a limiting protrusion 214 is also provided on the right side of the left rope binding mold 212. The arc-shaped groove 2122 of the left rope binding mold 212, together with the limiting protrusion 214, realizes the U-shaped opening of the bent metal wire, so that the metal wire is tied to the head of the bent rope.

[0032] like Figure 6 As shown, the second cam drive device 213 includes a second follower 2131 and a second cam 2132. The second follower 2131 is mounted on the left moving seat 211, and the second cam 2132 drives the left moving seat 211 to move left and right through the second follower 2131.

[0033] The working principle of the metal wire cutting and binding rope mechanism 2 in this embodiment is as follows:

[0034] After previous processing (such as straightening and conveying), the metal wire arrives at the metal wire cutting and binding mechanism 2. At this time, both the right cutting and binding device 22 and the left binding device 21 are in their initial positions, and the metal wire passes through the metal wire through hole, ready for cutting and binding operations. When the third cam drive device is activated, it drives the right moving seat 221 to move to the left, bringing the right cutting and binding die 222 closer to the mounting seat of the rope head bending mechanism 3. Under the action of the right cutting and binding die 222 and the mounting seat, the metal wire is cut. Subsequently, the right cutting and binding die 222 continues to move to the left, engaging with the lower ejector die 224. The ejector punch 2241 of the lower ejector die 224 rises under the action of the fifth cam drive device 2243, engaging with the second concave die 2222 of the right cutting and binding die 222, bending the cut metal wire into a U-shape. Simultaneously or shortly after the metal wire is bent into a U-shape, the second cam drive device 213 is activated, driving the left moving seat 211 to move to the right, bringing the left binding mold 212 closer to the bent metal wire. The punch 2121 and arc-shaped groove 2122 of the left binding mold 212 contact the metal wire, and through the action of the second bending guide groove 2123 and the limiting protrusion 214, the U-shaped opening of the metal wire is further bent, so that the metal wire is tied to the end of the bent rope. After completing the cutting, bending, and binding operations, the third cam drive device 223 and the second cam drive device 213 respectively drive the right moving seat 221 and the left moving seat 211 to return to their initial positions, preparing for the next operation.

[0035] The metal wire cutting and binding mechanism 2 of this embodiment has the following advantages:

[0036] This application utilizes a symmetrical and coordinated design of a left rope-binding device and a right rope-cutting device, along with directional guidance from a second guide component, to achieve continuous automated operation of metal wire cutting, U-shaped bending, and locking. This effectively replaces the traditional step-by-step manual operation mode, significantly reducing labor intensity and human error. Furthermore, the right rope-cutting device integrates both metal wire cutting and U-shaped bending functions, while the left rope-binding device completes the locking and fastening through a specific bending action. This integrates multiple processes into a single workstation, reducing equipment footprint and the number of transmission components, and improving the reliability of the mechanism. Moreover, the cutting and bidirectional bending processes can be completed in a single operation cycle, saving approximately 40% of the process time compared to traditional multi-station sequential processing, while also reducing metal wire waste, meeting the efficiency and cost control requirements of mass industrial production.
