[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Embodiment: A vehicle parts bending device, such as Figure 1-Figure 5 As shown, it includes a press brake 1, a V-shaped cutting frame 2, a punching plate 21 and an extended top plate 8. The press brake 1 is provided with a V-shaped cutting frame 2, and a punching plate 21 is installed on the top of the press brake 1. The punching plate 21 performs up and down reciprocating motion. The press brake 1 is connected to an extended top plate 8, which is located at the front end of the V-shaped cutting frame 2. The upper surface of the extended top plate 8 is provided with transverse fine stripes for preventing the parts to be bent from sliding back and forth. A conveying device is provided at the rear end of the press brake 1 for conveying processed parts. It also includes a pushing mechanism, a pushing assembly and a sliding assembly. A pushing mechanism for automatic loading is provided at the front end of the press brake 1, and a pushing assembly for pushing is provided at the bottom of the extended top plate 8. The press brake 1 is provided with a sliding assembly for transmitting power to the pushing assembly.

[0021] like Figure 2 and Figure 3 As shown, the pushing mechanism is mainly composed of a loading frame 3, an inverted L-shaped connecting frame 4, a cylinder 41 and a pushing rod 5. The loading frame 3 is connected to the press brake 1, and the rear end of the inverted L-shaped connecting frame 4 is connected to the front bottom of the loading frame 3. The front end of the inverted L-shaped connecting frame 4 is installed with a cylinder 41, and the piston rod of the cylinder 41 is connected to the pushing rod 5. The pushing rod 5 passes through the loading frame 3 and is slidably connected to the bottom of the loading frame 3. The diameter of the piston rod of the cylinder 41 is equal to the thickness of the pushing rod 5 and is not greater than the thickness of the part to be bent.

[0022] like Figure 3 and Figure 5As shown, the ejection assembly is mainly composed of a slider 7, a protrusion 72 and a guide rod 73. The guide rod 73 is connected to the press brake 1, the slider 7 is connected to the bottom of the extended top plate 8, and the side of the slider 7 is connected with a protrusion 72. The protrusion 72 is slidably connected to the guide rod 73. An annular groove 71 is opened on the side of the slider 7. Since the depth of the lower end of the annular groove 71 is greater than the depth of the top of the annular groove 71, a step 701 is provided at the rear end of the top of the annular groove 71, and a slope 702 is provided at the front end of the top of the annular groove 71.

[0023] like Figure 3 and Figure 4 As shown, the sliding assembly is mainly composed of a U-shaped frame 6, a push rod 61 and an elastic member 62. The front end of the push rod 5 is connected to the U-shaped frame 6, and the bottom of the U-shaped frame 6 is slidably connected to the push rod 61. An elastic member 62 is provided in the connection gap between the push rod 61 and the U-shaped frame 6. One end of the elastic member 62 is connected to the U-shaped frame 6, and the other end is connected to the push rod 61. The push rod 61 is slidably connected to the annular groove 71 of the slider 7.

[0024] The staff puts the stacked parts to be bent into the loading frame 3 of the pushing mechanism, and then turns on the press brake 1 and the cylinder 41 of the pushing mechanism. The cylinder 41 pushes the parts to be bent backward through the pushing rod 5. After the parts to be bent pass through the extended top plate 8, they are located on the V-shaped cutting frame 2. The cylinder 41 pushes the pushing rod 5 to the maximum stroke and stops. At the same time, due to the obstruction of the horizontal fine stripes on the upper surface of the extended top plate 8, the parts to be bent also stop. At this time, the bending line of the parts to be bent is directly above the V-shaped cutting frame 2, and while the cylinder 41 pushes the parts to be bent to move, the punching plate 21 reciprocates up and down under the drive of the press brake 1. When the parts to be bent are stationary, the punching plate 21 is already above the parts to be bent, and then squeezes the parts to be bent downward. The V-shaped cutting frame 2 and the punching plate 21 cooperate to complete the bending of the parts. After the parts are bent, the punching plate 21 moves upward and resets, and the cylinder 41 When the cylinder 41 is reset, the push rod 5 is pushed backward and the sliding assembly also moves backward. At this time, the sliding assembly follows the push rod 5 to move backward and cooperates with the lifting assembly to lift the bent parts from the front side. The parts are flipped and fall onto the conveying device at the rear end of the press brake 1 for backward transportation. Since the diameter of the piston rod of the cylinder 41 is equal to the thickness of the push rod 5 and is not greater than the thickness of the parts to be bent, the push rod 5 pushes the bottom part to be bent in the loading frame 3 each time, and after the push rod 5 is reset, the parts to be bent fall freely. After the sliding assembly moves backward and resets, the lifting assembly also falls, and then starts reciprocating motion. The piston rod of the cylinder 41 and the push rod 5 reciprocate back and forth, the stamping plate 21 reciprocates up and down, the sliding assembly follows the push rod 5 to reciprocate back and forth, and the lifting assembly reciprocates up and down through the sliding assembly, replenishing the parts in the loading frame 3 in the middle.

[0025] When the push rod 5 moves backward, the upper end of the U-shaped frame 6 moves accordingly, so that the push rod 61 at the lower end of the U-shaped frame 6 also slides backward in the annular groove 71 of the slider 7. When the push rod 5 moves to the rear end, the push rod 61 also slides to the rear end of the annular groove 71. Since the rear end of the top of the annular groove 71 is provided with a step 701 and the elastic member 62 is always in a compressed state, the elastic member 62 pushes the push rod 61 to fit tightly in the slider 7. When passing through the step 701, it falls from the step 701. Then the push rod 5 moves forward. Since the push rod 61 is blocked by the step 701, the push rod 61 moves along the inclined surface of the rear end of the annular groove 71. The groove slides downward, and the U-shaped frame 6 can only slide back and forth under the action of the cylinder 41. After the slider 7 is squeezed by the push rod 61, it slides upward along the guide rod 73, thereby lifting the extended top plate 8, lifting the bent parts, and flipping them over to fall onto the conveying device at the rear end of the press brake 1. The push rod 61 moves forward along the annular groove 71 of the slider 7. When the cylinder 41 is reset, the push rod 61 is located at the bottom of the front end of the annular groove 71. At this time, the slider 7 loses its support, and the protrusion 72 slides downward along the guide rod 73. The slider 7 falls, and the push rod 61 passes through the inclined surface 702 at the front end of the annular groove 71. After being squeezed by the inclined surface 702, it slides into the U-shaped frame 6, further compressing the elastic member 62, and the ejector assembly and the sliding assembly complete the reset.

[0026] like Figure 2 and Figure 3 As shown, it also includes a roller 31, a connecting shaft 32 and a roller 51. The bottom of the loading frame 3 is connected to the connecting shaft 32, and the roller 31 is rotatably connected to the connecting shaft 32. The upper and lower sides of the push rod 5 are rotatably connected to the roller 51. After the push rod 5 is connected to the roller 51, the overall thickness is still not greater than the thickness of the part to be bent.

[0027] The push rod 5 pushes the part to be bent. When it passes through the loading frame 3, the roller 31 rotates on the connecting shaft 32. The bottom of the part contacts the roller 31 and is pushed out smoothly. When the part falls, it contacts the roller 31 for buffering, thereby achieving the purpose of protecting the part. The rollers 51 arranged above and below the push rod 5 can reduce friction when contacting the upper part, and can also reduce friction when contacting the lower extending top plate 8, so that the cylinder 41 is subjected to less resistance, which is beneficial to extending the service life of the cylinder 41.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
