[0013] The present invention provides a bending device for processing aluminum materials of metal guide rails. It has the following beneficial effects:

[0014] (1) In the present invention, when the top mold 1 and the top mold 2 move downward, the positioning rod and the hollow rod will play a positioning effect on the top mold 1 and the top mold 2, so as to avoid the displacement of the top mold 1 and the top mold 2 and the bottom mold 1 and the bottom mold 2.

[0015] (2) In the present invention, after the positioning rod is inserted into the interior of the hollow rod, the No. 1 piston will squeeze the hollow rod and the interior of the hydraulic cylinder into the interior of the discharge pipe. The liquid in the discharge pipe will push the No. 2 piston and the sliding rod to move. When the top mold 1 and the top mold 2 descend to different heights, the lengths of the sliding rods on both sides extending out of the discharge pipe will be different, causing the sliding rod to push the swing plate to rotate. When the swing plate rotates, the arc plate will push the moving plate or the No. 6 spring will push the moving plate to move. When the moving plate moves, it will drive the rack plate to move. The movement of the rack plate will drive the gear, the rotating rod and the limiting block to rotate. The limiting block will limit the top mold 1 and the top mold 2 to move downward to prevent the top mold 1 and the top mold 2 from descending to different heights, which will affect the bending effect on the aluminum material.

[0016] (3) In the present invention, when the sliding rod moves, it will push the free ends of the swing plate and the elastic telescopic plate to move. When the free end of the elastic telescopic plate moves, it will drive the L-shaped frame to move, so that the L-shaped frame will push the protrusion and the connecting shaft to rotate. When the connecting shaft rotates, it will drive the umbrella-shaped plate and the semicircular plate to rotate. When the semicircular plate rotates, the impact block will hit the bottom mold 1. The vibration generated by the bottom mold 1 can improve the effect of the aluminum material being separated from the bottom mold 1. At the same time, the bottom mold 1 will push the impact block and the semicircular plate to move upward, so that the semicircular plate will drive the partition plate to move upward, and the through hole on the partition plate will be aligned with the oil outlet groove. The lubricating oil inside the storage device will intermittently enter the bottom mold 1 to prevent the aluminum material from being scratched by forcibly rubbing against the bottom mold 1 when being bent.

Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0028] The top of the concave block 11 is set as an inclined surface, the concave block 11 is in contact with the annular plate 9, a No. 1 spring piece is arranged between the annular plate 9 and the hollow rod 8, the elastic force of the No. 1 spring piece will support the annular plate 9, and a No. 2 spring piece is arranged between the concave block 11 and the fixed frame 7.

[0029] When this embodiment is working: the aluminum material is placed inside the bottom mold 1 2 and the bottom mold 2 3, and the top mold 1 4 and the top mold 2 5 are lowered, which will drive the positioning rod 6 to move downward. When the bottom mold 1 2 and the bottom mold 2 3 are misaligned with the top mold 1 4 and the top mold 2 5, the positioning rod 6 will not be able to accurately insert into the hollow rod 8 when it descends, causing the positioning rod 6 to contact the annular plate 9 when it descends and push the annular plate 9 to move downward.

The elastic telescopic plate 124 is fixedly installed on the top of the base 1, and the swing plate 125 is rotatably installed on the free end of the elastic telescopic plate 124. When the top mold 1 4 and the top mold 2 5 descend to different heights, the lengths of the sliding rods 123 on both sides extending out of the discharge pipe 122 will be different, causing the sliding rod 123 to push the swing plate 125 to rotate. The rotation of the swing plate 125 can be used to determine that the descending heights of the top mold 1 4 and the top mold 2 5 are not uniform.

[0031] The limiting device includes a rotating rod 128, which is rotatably installed on the top of the base 1, and a limiting block 1211 is fixedly installed on the top of the rotating rod 128. A moving plate 126 is slidably installed on the front of the bottom mold 2, and an arc plate 127 is fixedly installed on the side of the swing plate 125 close to the moving plate 126.

The rack plate 129 is meshed with the gear 1210, and the arc plate 127 is in contact with the moving plate 126. The movement of the rack plate 129 will drive the gear 1210, the rotating rod 128 and the limiting block 1211 to rotate. The limiting block 1211 will limit the top mold 14 and the top mold 25 from moving downward to prevent the top mold 14 and the top mold 25 from descending to different heights at the same time, which affects the bending effect on the aluminum material.

[0032] A No. 3 spring piece is arranged between the No. 1 piston and the hollow rod 8, a No. 4 spring piece is arranged between the No. 2 piston and the discharge pipe 122, the sliding rod 123 is in contact with the swing plate 125, a No. 5 spring piece is arranged between the swing plate 125 and the elastic telescopic plate 124, and a No. 6 spring piece is arranged between the movable plate 126 and the bottom mold 2. The elastic force of the No. 6 spring piece will drive the movable plate 126 to move.

[0033] A protection frame 1212 is fixedly installed on the top of the base 1 , and the rack plate 129 slides through the protection frame 1212 , so that the protection frame 1212 can protect and support the rotating rod 128 .

[0034] The disengagement device includes a connecting shaft 131, a protrusion 132, an L-shaped frame 133, an umbrella-shaped plate 134, a semicircular plate 135 and an impact block 136. The connecting shaft 131 is rotatably mounted on the top of the base 1, the protrusion 132 is fixedly mounted on the circumferential surface of the connecting shaft 131, the L-shaped frame 133 is fixedly mounted on the free end of the elastic telescopic plate 124, the umbrella-shaped plate 134 is fixedly mounted on the circumferential surface of the connecting shaft 131, the semicircular plate 135 is fixedly mounted on the bottom of the umbrella-shaped plate 134 through an elastic member, the impact block 136 is fixedly mounted on the bottom of the semicircular plate 135, and a clockwork spring is arranged between the connecting shaft 131 and the base 1. When the semicircular plate 135 rotates, the impact block 136 will hit the bottom mold 2. The vibration generated by the bottom mold 2 can improve the effect of aluminum material being separated from the inside of the bottom mold 2.

[0035] A storage device 137 is fixedly installed on the top of the umbrella plate 134, a discharge pipe 138 is fixedly installed on the side of the umbrella plate 134 close to the bottom mold 2, an oil outlet groove is provided inside the umbrella plate 134, and the storage device 137 is connected to the oil outlet groove, a partition 139 is fixedly installed on the top of the semicircular plate 135, and a through hole is provided on the surface of the partition 139, and the partition 139 slides through the umbrella plate 134, and the lubricating oil inside the storage device 137 will intermittently enter the interior of the bottom mold 2 to prevent the aluminum material from being scratched by forcibly rubbing against the bottom mold 2 when being bent.

[0036] When this embodiment is working: when the top mold 1 4 and the top mold 2 5 descend, the positioning rod 6 will be driven to move downward. After the positioning rod 6 is accurately inserted into the interior of the hollow rod 8, the positioning rod 6 will contact the No. 1 piston and push the No. 1 piston to move downward. When the No. 1 piston moves downward, it will squeeze the liquid inside the hollow rod 8 into the interior of the hydraulic cylinder 121. The increase in liquid inside the hydraulic cylinder 121 will push the No. 2 piston and the sliding rod 123 inside the discharge pipe 122 to move. When the sliding rod 123 moves, it will push the swing plate 125 to move. When the heights to which the top mold 1 4 and the top mold 2 5 descend are not uniform, the depths of the positioning rods 6 on both sides inserted into the hollow rod 8 will be different, resulting in different lengths of the sliding rod 123 extending out of the discharge pipe 122. The force with which the sliding rods 123 on both sides push the swing plate 125 on both sides will be Different, the swing plate 125 will rotate on the elastic telescopic plate 124, and the swing plate 125 will drive the arc plate 127 to move when it rotates. The left rotation of the arc plate 127 will push the movable plate 126 to move. When the arc plate 127 rotates to the right, the arc plate 127 will not be able to support the movable plate 126, and the elastic force of the No. 6 spring will drive the movable plate 126 to move to the right. When the movable plate 126 moves, it will drive the rack plate 129 to move. When the rack plate 129 moves, it will drive the gear 1210 and the rotating rod 128 to rotate. When the rotating rod 128 rotates, it will drive the limiting block 1211 to move downward. After the limiting block 1211 rotates, it will be at the bottom of the top mold 1 4 and the top mold 2 5. The limiting block 1211 will prevent the top mold 1 4 and the top mold 2 5 from continuing to move downward;

[0037] When the top mold 14 and the top mold 25 drive the positioning rod 6 to be normally inserted into the interior of the hollow rod 8, the sliding rod 123 will push the free ends of the swing plate 125 and the elastic telescopic plate 124 to move, and the free end of the elastic telescopic plate 124 will drive the L-shaped frame 133 to move. When the L-shaped frame 133 moves, it will contact the protrusion 132, so that when the L-shaped frame 133 moves, it will push the protrusion 132 and the connecting shaft 131 to rotate. The rotation of the connecting shaft 131 will drive the umbrella-shaped plate 134 to move away from the bottom mold 12, so as to avoid the top mold 14 and the top mold 25 from pressing the umbrella-shaped plate 134 when they descend. When the top mold 14 and the top mold 25 rise, the elastic force of the scroll spring will drive the connecting shaft 131 to rotate, and the connecting shaft 131 will drive the umbrella-shaped plate 134 to move in the direction of the bottom mold 12. When the umbrella-shaped plate 134 moves, it will drive the elastic member The semicircular plate 135 moves toward the top of the bottom mold 2. When the semicircular plate 135 moves, it will drive the impact block 136 to move. When the impact block 136 moves, it will hit the bottom mold 2 and the aluminum material inside the bottom mold 2. The aluminum material and the bottom mold 2 will vibrate after being hit, which makes it easier for the aluminum material to separate from the bottom mold 2. At the same time, when the bottom mold 2 contacts the impact block 136, the bottom mold 2 will push the impact block 136 and the semicircular plate 135 to move upward. When the semicircular plate 135 moves upward, it will drive the partition 139 to move upward. When the partition 139 moves upward, it will drive the through hole to move upward. The through hole moves upward and is connected to the oil outlet groove, so that the lubricating oil inside the storage device 137 is discharged from the discharge pipe 138 through the oil outlet groove and the through hole, so that the lubricating oil inside the storage device 137 is intermittently added to the inside of the bottom mold 2.
