Description

Technical Field

[0001] This utility model relates to the field of cable coiling technology, specifically to an automatic wire coil cutting and bending device. Background Technology

[0002] In the automated production process of cable winding and packaging, cable winding, cable tying, and heat shrink packaging are crucial subsequent processes. This typically includes: automatically winding the cable into a neat coil using a cable tying machine, cutting the cable after it reaches a preset length, and securing it with cable ties; then wrapping the bundled coil with heat shrink film to achieve dustproofing, moisture protection, aesthetic appeal, and ease of transportation and storage. However, due to the inherent structural rigidity and resilience of cables, when they are bundled with cable ties after winding, the end of the coil (i.e., the cable tip) tends to curl outwards, forming a sharp, irregular protrusion. This protrusion can easily puncture the packaging film during subsequent heat shrink packaging: as the heat shrink film shrinks, it adheres tightly to the coil, and the protruding, hard cable tip, like a needle point, punctures the film, causing damage and air leakage, affecting the product's appearance and failing to provide protection. Furthermore, operators handling the product face the risk of hand injuries, posing a safety hazard.

[0003] To solve the problem of the cable ends sticking outwards after being cut, the technical solution of this patent was developed. Utility Model Content

[0004] The technical problem solved by this utility model is to provide an automatic cutting and bending device for wire coils that is compact in structure and reliable in operation.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an automatic wire coil cutting and bending device, including a left mounting base, a right mounting base, and a set of guide shafts connecting the left mounting base and the right mounting base; it also includes a fixed blade group mounted on the guide shaft and a movable blade group used in conjunction with the fixed blade group; the right mounting base is also equipped with a cutting cylinder for driving the movable blade group to move on the guide shaft, and the driving end of the cutting cylinder is connected to the movable blade group through a cylinder connector; the movable blade group is also equipped with a top wire plate to bend the wire before cutting the wire.

[0006] Furthermore, the fixed blade assembly includes a fixed blade mounting seat fixed to the guide shaft and a fixed cutting blade mounted on the fixed blade mounting seat.

[0007] Furthermore, the movable blade assembly includes a movable blade mounting seat mounted on a guide shaft and a movable cutter mounted on the movable blade mounting seat; the cylinder connector is connected to the movable blade mounting seat.

[0008] Furthermore, the top plate is installed on the outside of the movable cutter.

[0009] Furthermore, the top plate is provided with multiple adjustment holes.

[0010] Furthermore, it also includes guide poles for guiding cables.

[0011] Furthermore, a cable guide wheel assembly is also installed on the other side of the fixed blade assembly away from the guide rod.

[0012] The beneficial effects of this utility model are: by bending the cable before cutting it, and integrating bending and cutting into one operation, this utility model has a simple structure, reasonable layout, and simple and convenient operation process.

[0013] By designing a top cable plate and installing it in a suitable position, the cable is bent before being cut. This ensures that the cut end of the cable naturally folds and adheres to the coiled coil, effectively preventing the cable end from sticking up and making the coiled coil packaging more aesthetically pleasing. The top plate also features adjustment holes, allowing operators to easily adjust the extension distance of the top cable plate according to different cable diameters and materials, enhancing the equipment's versatility.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1 to 3The automatic wire coil cutting and bending device shown includes a left mounting base 11 and a right mounting base 12 fixed to the frame by bolts and nuts. A set of guide shafts 13 connects the left and right mounting bases 11 and 12. The set of parallel guide shafts 13 includes two shafts, with bearing seats securing both ends of each shaft to the left and right mounting bases 11 and 12 respectively. It also includes a fixed blade assembly mounted on the guide shafts 13 and a movable blade assembly that works in conjunction with the fixed blade assembly. The two guide shafts 13 form a stable support structure, ensuring the smooth movement and precise guidance of the movable blade assembly as it moves along the guide shafts 13. A cutting cylinder 18 is also installed on the right mounting base 12 to drive the movable blade assembly to move on the guide shaft 13. The drive end of the cutting cylinder 18 is connected to the movable blade assembly through the cylinder connector 17. The cutting cylinder 18 is the power source for the entire cutting and bending action. When the drive end of the cutting cylinder 18 extends, it drives the movable blade assembly to slide along the guide shaft 13 toward the fixed blade assembly. When the drive end of the cutting cylinder 18 retracts, it drives the movable blade assembly to reset along the guide shaft 13. A top plate 16 is also installed on the movable blade assembly to bend the cable before cutting it. The top plate 16 includes a fixed mounting part and a bending part. When the top plate 16 is installed, the bending part protrudes from the movable blade assembly toward the fixed blade assembly, which ensures that the cable is bent before being cut.

[0017] Based on the above, the fixed blade assembly includes a fixed blade mounting seat 141 fixed to the guide shaft 13 and a fixed cutter 142 mounted on the fixed blade mounting seat 141. The fixed blade mounting seat 141 is fixed to the guide shaft 13 by bolts and serves as the stationary blade part when cutting cables. The movable blade assembly includes a movable blade mounting seat 151 mounted on the guide shaft 13 and a movable cutter 152 mounted on the movable blade mounting seat 151. The movable blade mounting seat 151 is mounted on the guide shaft 13 by a linear bearing; a cylinder connector 17 is connected to the movable blade mounting seat 151. The movable blade mounting seat 151 is connected to the cylinder connector 17, and a cutting cylinder 18 drives the movable blade mounting seat 151 to slide on the guide shaft 13, serving as the moving blade part during cable cutting operations.

[0018] Based on the above, the top plate 16 is installed on the outside of the movable cutter 152, and the top plate 16 is installed on the side close to the cable coil. This ensures that the part of the cable that is bent by the top plate 16 is coiled on the cable coil after the cable is cut.

[0019] Based on the above, in order to accommodate different specifications of cables with varying degrees of bending, multiple adjustment holes 161 are provided on the top plate 16. This ensures that thicker cables can also be bent or that the curvature of the bend can be adjusted.

[0020] Building upon the above, a guide rod 21 is also included to guide the cable. This guide rod is installed in front of the cable inlets of the fixed and movable cutter groups, constraining the cable feed path and ensuring the cable is fed into the correct position between the fixed cutter 142 and the movable cutter 152. On the other side of the fixed cutter group away from the guide rod 21, a cable guide wheel assembly 22 is also installed. This assembly consists of two vertically mounted rollers. The cable passes through the channels between the two rollers, reducing friction and improving cable cutting accuracy.

[0021] Working principle: The cable passes through the guide rod 21, through the gap between the fixed blade group and the movable blade group, and then through the cable guide wheel group 22 before being coiled in the cable coiling device. When the cable coil reaches the predetermined length, the control system sends a cutting command to the cutting cylinder 18. The cutting cylinder 18 drives the movable blade mounting base 151 to move towards the fixed blade group. During this movement, the top bend of the top plate 16 will first contact the cable. As the movable blade group continues to move towards the fixed blade group, the top plate 16 pushes the cable forward, causing the cable to form a bend with the same shape as the top bend. When the cutting edge of the movable cutter 152 and the cutting edge of the fixed cutter 142 are both in contact with the cable, the cable cutting action begins, the cable is precisely cut, and the end of the cable has been bent and shaped.

[0022] After the cable is bent and cut, the cutting cylinder 18 drives the movable blade mounting base 151 to reset along the guide shaft 13, preparing for the next cable bending and cutting. At the same time, the coiled cable that has been bent and cut enters the cable tying or packaging process.

[0023] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
