Specific Embodiment

[0035] The following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0036] As Figure 1-8 shown, an automatic bending and forming device for the rods of a frame of the present utility model includes a frame, a rod feeding device 1, a rod positioning device 2, a rod bending device 3, and a bracket discharging device 4;

[0037] The rod feeding device 1 is arranged on the frame and is used to convey the rod 100 to the rod positioning device 2;

[0038] The rod positioning device 2 is arranged on the frame and is located beside the rod feeding device 1. The rod positioning device 2 is used to receive the rod 100 from the rod feeding device 1 and to position the rod 100;

[0039] The rod bending device 3 is arranged on the frame and is located beside the rod positioning device 2. The rod bending device 3 is used to perform corresponding bending and forming on the rod 100 located on the rod positioning device 2 so that the rod 100 is formed into a U-shaped bracket 200;

[0040] The bracket discharging device 4 is arranged on the frame and is located beside the rod positioning device 2. The bracket discharging device 4 is used to unload the U-shaped bracket 200 from the rod positioning device 2. By integrating the rod feeding device, the rod positioning device, the rod bending device, and the bracket discharging device on one frame, the present utility model can realize the automatic feeding, positioning, bending, and discharging operations of the rod, achieve automated processing operations, and has the characteristics of a compact structure, high integration, high bending efficiency, and guaranteed quality of the finished product after bending.

[0041] During operation, the rod feeding device transports the rod to the rod positioning device for positioning. Then, the rod bending device bends the rod located on the rod positioning device accordingly to form it into a U-shaped bracket. After that, the bracket unloading device unloads the U-shaped bracket 200 from the rod positioning device 2. Therefore, by using the present utility model, automatic processing and forming of the U-shaped bracket can be achieved.

[0042] As Figure 1 、 2 、shown in 6, the rod feeding device 1 includes a feeding mounting frame 11 provided on the frame. On the feeding mounting frame 11, there is a rod conveying aisle 12 that is inclined towards the rod positioning device 2 side and is used for conveying the rod 100. Above the rod positioning device 2 on the feeding mounting frame 11, there is a rod conveying channel 121 that is communicated with the output end of the rod conveying aisle 12 and is used for a single rod 100 to pass through, which can avoid outputting multiple rods to the rod positioning device at a time and affecting subsequent operations, ensuring the normal operation of the equipment. Inside the rod conveying aisle 12, there is a rod blocking member 13 that is movably provided for blocking the rod 100 on the rod conveying aisle 12. On the feeding mounting frame 11, there is a blocking driving member for driving the rod blocking member 13 to act accordingly. In this embodiment, the rod conveying aisle can also arrange multiple rods in an orderly manner, avoiding interference between multiple rods and affecting the conveying. At the same time, since the rod conveying aisle is inclined, there is no need to additionally increase a rod pushing mechanism to push the rod to act accordingly, that is, the rod can automatically move towards the rod conveying channel side, with a simple structure, low manufacturing cost, and reasonable design. Among them, the blocking driving member can be a blocking driving cylinder, etc. The driving end of the blocking driving cylinder is connected to the rod blocking member 13 to drive the rod blocking member 13 to move up and down relative to the rod conveying aisle 12, as Figure 6 shown.

[0043] As Figure 1 、 2, as shown in Fig. 6, in order to reduce the waiting time and improve the conveying efficiency, the rod feeding device 1 further includes a rod storage bin 14 provided on the feeding mounting frame 11 for storing the rods 100. The feeding mounting frame 11 is further provided with a rod lifting device 15 for conveying the rods 100 in the rod storage bin 14 to the rod conveying aisle 12. The rod lifting device 15 includes a rod lifting driving member 151 provided on the feeding mounting frame 11. The driving end of the rod lifting driving member 151 is provided with a rod lifting rod 152 located inside the rod storage bin 14 and used for lifting the rods 100 in the rod storage bin 14. The upper end of the rod lifting rod 152 is provided with a lifting inclined surface 153 inclined toward the rod conveying aisle 12. During conveying, the rod lifting driving member 151 drives the rod lifting rod 152 to move upward relative to the rod storage bin 14. At this moment, the lifting inclined surface 153 lifts the rod 100 to the input end position of the rod conveying aisle 12, so that the rod 100 automatically enters the rod conveying aisle 12.

[0044] As Figure 6 shown, in order to facilitate the lifting of the rods, the inner bottom of the rod storage bin 14 is inclined toward the rod conveying aisle 12, and the rod lifting rod 152 is located at the lowest position of the rod storage bin 14. When the rod lifting rod 152 lifts the rod 100 at the lowest position of the rod storage bin 14 to the rod conveying aisle 12 and returns to its original position, the rods 100 at the other positions of the rod storage bin 14 will automatically move to the lowest position of the rod storage bin 14 and be lifted by the rod lifting rod 152 next time. The design is reasonable.

[0045] As Figure 1-5 shown, in order to ensure reliable and convenient positioning, the rod positioning device 2 includes a positioning mounting frame 21 and a rod pushing and positioning assembly 24 provided on the machine frame. The positioning mounting frame 21 is provided with a positioning fixing seat 22, and a rod positioning groove 23 for receiving the rods 100 of the rod feeding device 1 is provided on the positioning fixing seat 22. The rod pushing and positioning assembly 24 includes a rod pushing driving member 241 provided on the positioning mounting frame 21 and beside the positioning fixing seat 22. The driving end of the rod pushing driving member 241 is provided with a rod pushing block 242 for pushing the corresponding end of the rod 100 on the rod positioning groove 23. In this embodiment, the rod positioning groove 23 can limit the movement of the rod 100 in the front-back and downward directions along the machine frame, which can ensure the stability of the rod relative to the bending moving die during the bending process, facilitate the stable action of the bending moving die on the rod bending, and at the same time, the rod pushing and positioning assembly 24 acts on the corresponding end of the rod 100 to make the rod 100 in a set position, ensuring that the bending part of the bending moving die acts on each rod 100 is the same, and ensuring the quality of the U-shaped bracket.

A sliding block driving member 223 for driving the corresponding sliding of the positioning sliding block 222 is provided on the positioning mounting frame 21. The rod positioning groove 23 is located between the positioning blocking block 221 and the positioning sliding block 222. When the rod 100 enters the rod positioning groove 23, the sliding block driving member 223 drives the positioning sliding block 222 to slide towards the positioning blocking block 221 until the positioning notch 224 is engaged with the rod 100, at which time the forward and backward, up and down movement of the rod 100 relative to the machine frame is restricted. In order to facilitate receiving the positioned rod, a guiding inclined surface is provided at the notch position of the rod positioning groove 23. Among them, the sliding block driving member 223 can be a sliding driving cylinder or the like.

[0047] As Figure 3 As shown in the figure, in order to improve the bending efficiency, the rod bending device 3 includes a bending mounting frame 31 provided on the machine frame. A bending rotating seat 32 is rotatably provided on the bending mounting frame 31 and beside the rod positioning device 2.

An eccentric bending movable die 322 is provided on the bending rotating seat 32 for bending the corresponding end of the rod 100 around the bending fixed die 321 during the rotation of the bending rotating seat 32. A bending driving member 33 for driving the bending rotating seat 32 to rotate is provided on the bending mounting frame 31. The bending driving member 33 is a bending driving motor. A bending transmission mechanism 34 is provided between the output shaft of the bending driving motor and the bending rotating seat 32. The bending transmission mechanism 34 includes a driving gear 341 that is synchronously connected to the output shaft of the bending driving motor and a driven gear 342 that is coaxially and synchronously connected to the bending rotating seat 32 and meshes with the driving gear 341. During bending, the bending driving motor drives the corresponding rotation of the bending rotating seat 32 through the transmission cooperation of the driving gear 341 and the driven gear 342, so that the bending fixed die 321 acts on the bending part of the rod 100 to bend and form around the bending fixed die 321. After the bending is completed, the bending driving motor drives the bending rotating seat 32 to rotate and reset.

[0048] As Figure 1-5As shown, in order to bend and position products of different specifications, the two rod bending devices 3 are correspondingly arranged on both sides of the rod positioning device 2; a spacing adjustment mechanism 5 for adjusting the spacing between the two rod bending devices 3 is provided on the frame. The spacing adjustment mechanism 5 includes a spacing adjustment lead screw 51 rotatably arranged on the frame. Two spacing adjustment nuts 52 are movably connected to the spacing adjustment lead screw 51. Each spacing adjustment nut 52 is fixedly connected to the corresponding rod bending device 3. In this embodiment, the connection mode between one spacing adjustment nut 52 and the spacing adjustment lead screw 51 is a forward rotation connection, and the connection mode between the other spacing adjustment nut 52 and the spacing adjustment lead screw 51 is a reverse rotation connection. When operating the spacing adjustment lead screw 51 to rotate relative to the frame, the two rod bending devices 3 can move closer to each other or move away from each other. In this embodiment, the rod positioning device and the rod bending device on the left are both arranged on the left sliding plate, and the rod positioning device and the rod bending device on the right are both arranged on the right sliding plate.

[0049] As Figure 1 , 2 As shown in Figures 7, in order to facilitate blanking, the bracket blanking device 4 includes a blanking mounting frame 41 arranged on the frame.

A blanking clamping cylinder 46 is arranged on the second sliding plate 45. A clamping claw 47 for clamping the U-shaped bracket 200 on the rod positioning device 2 is arranged at the driving end of the blanking clamping cylinder 46. When the clamping claw 47 clamps the U-shaped bracket on the rod positioning device, the second sliding driving member 44 drives the second sliding plate 45 to drive the blanking clamping cylinder 46 to slide upward relative to the frame. Then, the first sliding driving member 42 drives the first sliding plate 43 to slide away from the rod positioning device, so that the blanking clamping cylinder 46 slides to the blanking position. Finally, the blanking clamping cylinder 46 drives the clamping claw 47 to release the U-shaped bracket.
