The work is very efficient and the degree of automation is high, which solves the long-standing manual folding in the construction industry. Bending welding restricts the development of the industry.

During specific use, for the convenience of understanding the present invention, the working process of the device is divided into the following steps and described respectively;

Feeding of the steel wire: the steel wire is divided into the middle steel wire 14, the left steel wire 141, and the right steel wire 142. The feeding of the middle steel wire is completed by the feeding mechanism, as shown in Figure 2. When the middle steel wire is not fed, the feeding cylinder is reset, and the clamp cylinder is reset to obtain When ordering to feed, the clamp cylinder works to fix the middle steel wire through the interaction between the movable part of the clamp and the fixed part of the clamp, and then sends the middle steel wire to the bending place for a bending length through the feeding of the feeding cylinder. And the steel wire on the left side and the steel wire on the right side realize feeding through the motion of the pulling mechanism.

Combined action of feeding and pulling materials: as shown in Figure 1, when the feeding mechanism transports the middle steel wire to the bending mechanism, the pushing cylinder does not work, and the pushing mechanism is on the far left side of the workbench, see Figure 6, clamping cylinder Not working, when the feeding of the feeding mechanism is completed and the bending begins to bend, the clamping cylinder works, and after the clamping movable part and the clamping fixed part fix the middle steel wire, the middle steel wire is sent to the bending mechanism through the pushing cylinder Conveying (the stroke of the pushing cylinder is controlled by the distance between the photoelectric switch A and the power-off switch B), at this time the clamp cylinder resets, the feeding cylinder resets, the feeding mechanism returns to the left side of the workbench, and waits for the next feeding.

Bending process: as shown in Figure 3 and Figure 4, when the middle steel wire transports a bent length to the bending place (at this time, the pulling mechanism simultaneously transports the bent and welded workpiece to the right side of the workbench) , see Figure 9-1, the thimble goes up, the swing piece rotates counterclockwise along the fixed axis, and fixes the right side of the middle steel wire together with the thimble (see Figure 8, 9-2), the bending needle is pushed by the bending cylinder Next, move along the track groove of the bending track control panel, and the track of the movement is the climbing section—the farthest point—the return section—the origin (see Figure 9-3, 9-4). When the bending needle moves, The pushing cylinders work together to push the middle steel wire to the bending mechanism.

In order to facilitate the understanding of the present invention, the movement track of the bending needle is further described. The bending cylinder is fixed on the workbench through the bending hinge. When the bending cylinder is working, the bending head moves along the long groove of the bending swing plate (See Figure 5), the bending needle is in the track groove. When moving, the bending head first touches the outer surface of the climbing section and moves along the climbing section. Since the climbing section is a curved section, the movement of the rolling bearing in the guide groove Realize that the bending cylinder and the bending head swing along the bending hinge until the bending needle moves to the farthest point. Utilizing the motion inertia of the bending needle and the special-shaped design of the track groove (the space in the return section is large and the transition is round, see Figure 9-1), when the bending cylinder shrinks, the bending head moves along the return section until it reaches the origin, and waits next bend.

In order to facilitate the understanding of the present invention, the trajectory of the middle steel wire is further described (see Figures 9-1, 9-2, 9-3, 9-4), the right end of the middle steel wire is fixed, and the bending needle is against the middle steel wire Moving along the track groove, at the same time, the pushing mechanism realizes the feeding of the middle steel wire, which is equivalent to the process of bending the middle steel wire along the thimble to form a V shape, and multiple bending makes the middle steel wire a W shape.

Welding: During the time when the feeding mechanism and the pulling mechanism are reset, the wire frame does not move, as shown in Figure 13, Figure 14, and Figure 15, the left positioning cylinder moves, and under the guidance of the left guide block, the left positioning plate extends (The situation of the right positioning mechanism is the same), the left positioning head and the right positioning head uniquely limit the positions of the left steel wire, the middle steel wire and the right steel wire. At the same time, the welding cylinder moves, and the welding The head moves down to weld the middle steel wire, the left steel wire and the right steel wire together.

Flattening: As shown in Figure 18, during the working time of the feeding mechanism and the pulling mechanism, the bent and welded steel wire frame moves relative to the flattening mechanism, and the rolling body rolls freely around the roller shaft. Since the rolling body has a certain Quality, the wire rack does not warp.

Material cutting: As shown in Figure 19 and Figure 20, the steel wire frame does not move during the reset time of the feeding mechanism and the pulling mechanism. When the steel wire frame outside the device reaches the required length, the PLC controls the material cutting mechanism to cut material. The details are as follows; the material cutting cylinder moves, the cutter moves down, and the cutter cuts off the wire frame along the end face of the pressing platform.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
