[0055] Furthermore, the bending module is equipped with multiple stop block modules, each of which includes a cylinder 96 and a vertical rod 97. The vertical rod 97 is mounted on the cylinder 96, and the cylinder 96 drives the vertical rod 97 to move up and down.

[0056] Implementation method 1: Figure 19 For example, the style of the steel wire: In use, this invention first adjusts the position or distance between bending modules one, two, three, and four according to the desired folding pattern of the steel wire. Specifically, rotating wheel one drives lead screw one, synchronous pulley, and synchronous belt to rotate. Lead screw one drives lead screw nut one and small base plate to move, allowing the two small base plates to move in opposite directions or towards each other, thus adjusting the X-axis distance of the bending modules. Simultaneously, rotating wheel two drives lead screw two and / or lead screw three to rotate, thereby adjusting the Z-axis distance of the bending modules. Furthermore, the Y-axis distance of the bending modules can be adjusted via the Y-axis moving mechanism, controlling the lifting and lowering of the bending modules and switching them between working and non-working states to meet the needs of different steel wire bending.

[0057] The robotic arm grasps the steel wire, compares it on the wire feeder, and then it slides down from the rectangular tube. The steel wire automatically falls between the top block and the fixed shaft of bending module one and bending module two. Then, the clamping cylinder pushes the pressure head to move. The pressure head provides a certain support force to the middle section of the steel wire to prevent problems such as bending in the middle section or incomplete bending angle during bending. Then, the rotary cylinder one drives the fixed shaft and the rotating disk to rotate. During the rotation of the rotating disk, the steel wire is squeezed by the interaction of the top block, so that the steel wire bends and folds with the fixed shaft. In the above process, bending module one and bending module two can work synchronously.

[0058] After the first bending operation is completed, cylinder four in the stop block module where bending modules three and four are located drives the upright to move upward, blocking both ends of the steel wire (to prevent the steel wire from rebounding slightly, and to ensure that the steel wire is positioned between the top block and the fixed shaft during the upward movement of bending modules three and four). Then, the cylinder of the Y-axis moving mechanism pushes bending modules three and four upward, and after moving upward, the steel wire is positioned between the top block and the fixed shaft. Then, the pressing cylinder drives the pressure head to move, and the pressure head also provides a certain support force for the steel wire to facilitate bending. Then, the rotary cylinder one of bending modules three and four works, and the bending operation of the steel wire is completed under the action of the top block and the fixed shaft. Afterward, all mechanisms are reset.

[0059] While the steel wire is being bent, the snap fastener feeding mechanism operates. The snap fasteners enter the conveyor channel under the action of the vibratory feeder, and then, under the action of the vibrator, enter the feed hole of the feeding mold. Subsequently, the rodless cylinder drives the feeding mold to move upwards. After moving upwards, the feed hole is aligned with the ejector pin. Then, the push rod cylinder pushes the ejector pin into the feed hole, and the ejector pin pushes the snap fasteners in the feed hole onto the snap fastener guide rail. At this time, multiple snap fasteners are arranged sequentially on the snap fastener guide rail. The front snap fastener enters the lower pressing groove under the push of the subsequent snap fasteners. Then, each mechanism resets, and then the cylinder three drives the template to move, causing the mold... Mold cores 1, 2, and 3 move to the lower end of the pressure rod. At this time, the lower pressure groove and the wire positioning groove are on the same straight line. Then, the robot arm grabs the wire and moves it to the wire crimping mechanism. The two ends of the wire are placed in the wire positioning groove and the lower pressure groove. Then, the hydraulic cylinder drives the pressure rod to move down. Under the action of the lower pressure groove and the upper pressure groove, the buckle is crimped with the wire. After the crimping is completed, the mechanism returns to its original position. Cylinders 1 and 2 push the top block to move. The top block pushes the wire out of the lower pressure groove and pushes it out. The pushed-out wire falls directly onto the support rod of the forming wire collecting mechanism.

[0060] During the crimping process between the steel wire and the buckle, part of the steel wire overlaps on the support rod.

[0061] During implementation, when one side of the support rod carries a certain amount of shaped steel wire, the rotary cylinder two drives the rotating shaft mounting plate to rotate, so that the other side of the support rod continues to complete the collection of the shaped steel wire.

[0062] When the support rods have collected a certain amount of formed steel wire, cylinder five drives the formed steel wire collecting mechanism to move outward, facilitating the unified collection of the formed steel wire.

[0063] like Figure 19 As shown, when steel wire 98 is crimped with buckle 78, the steel wire is bent in one of the bending states.

[0064] When using this invention, a dedicated robotic arm is provided to grasp and transfer the steel wire.

[0065] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
