AI Technical Summary
When existing bending equipment bends the door slide rails, it easily causes bulging deformation on the upper surface of the slide rails, and it is difficult to effectively flatten them.
The device employs a combination of bending mold, built-in mold, U-shaped frame, rolling roller and drive mechanism. The rolling roller rolls on the upper surface of the slide rail and works with the built-in mold to limit the movement, thereby flattening the protrusion.
This effectively prevents the upper surface of the slide rail from bulging and deforming during bending, ensuring that the surface of the slide rail is flat after bending, which facilitates subsequent material cutting operations.

[0015] The beneficial effects of this invention are: 1. In use, the slide rail body to be bent is placed on the upper surface of the processing table. The bent mold and positioning clamping mechanism clamp and position the slide rail body to prevent displacement during bending. After the slide rail body is placed, the drive mechanism two causes the inner mold to extend from one side of the bent mold (because the inner mold is arc-shaped, after extending from one side, part of the inner mold moves to the inner surface of the slide rail body). Then, the U-shaped frame two is rotated 90° towards the bending mold. At this time, the limiting mechanism limits and fixes the U-shaped frame two. The rolling roller two then rolls on the upper surface of the slide rail body. Then, under the action of the clamping mechanism, the second rolling roller applies a downward force. Then, the first driving mechanism drives the sliding seat, the first U-shaped frame, the first rolling roller, the second U-shaped frame, and the second rolling roller to move together. During this process, the first rolling roller, in conjunction with the bending die, processes one end of the slide rail body into a bent shape. During this process, the second rolling roller moves and rolls on the upper surface of the slide rail body. In conjunction with the built-in die, it flattens any protrusions on the upper surface of the slide rail body (the lower surface of the slide rail body cannot produce protruding deformation due to the limitation of the upper surface of the processing table and the lower surface of the built-in die). Then, the sliding seat, the first U-shaped frame, the first rolling roller, the second U-shaped frame, and the second rolling roller return to their initial positions. Finally, the bent slide rail body is unloaded.
[0016] 2. In the initial state, U-shaped frame two is positioned away from the bending mold to avoid affecting the placement of the slide rail body to be bent. After the slide rail body to be processed is positioned, the operator uses the handle to make the rotating plate, U-shaped frame two, and rolling roller two rotate 90° towards the bending mold until the iron block is in contact with the side of the electromagnet. At this time, the electromagnet is energized and attracts the iron block, thereby limiting and fixing the rotating plate and U-shaped frame two. This allows U-shaped frame two and rolling roller two to move together with U-shaped frame one, causing rolling roller two to roll the upper surface of the slide rail body. After the slide rail body is bent, U-shaped frame one drives U-shaped frame two and rolling roller two to return to the initial position. Then, the electromagnet is de-energized, releasing the attraction of the iron block. Then, the operator uses the handle to push U-shaped frame two away from the bending mold to avoid affecting the subsequent unloading operation of the slide rail body.
[0017] 3. In the initial state, the telescopic end of the pusher cylinder is in the retracted state, which, together with the positioning plate, positions the slide rail body. After the slide rail body is positioned and bent into the required shape, the U-shaped frame one, along with the rolling roller one, U-shaped frame two, and rolling roller two, returns to the initial position. Then, the telescopic end of the pusher cylinder extends, thereby pushing the bent slide rail body to move. This causes the bent end of the slide rail body to move away from the bending mold, making it easier for workers to pick up the slide rail body and unload it. Attached Figure Description

Detailed Implementation
[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0021] Reference Figures 1-12 A bending device for manufacturing car door sliding rails includes a processing table 100. A bending mold 101 is fixed on the upper surface of the processing table 100. An internal mold 102 is movably disposed on the bending mold 101. An arc-shaped groove 103 is formed on the upper surface of the processing table 100. A sliding seat 104 is slidably disposed within the arc-shaped groove 103. A U-shaped frame 105 is fixed on the upper surface of the sliding seat 104. A rolling roller 106 is rotatably disposed on the inner wall of the U-shaped frame 105. A U-shaped frame 2 107 is provided on the side, and a rolling roller 2 108 is rotatably arranged inside the U-shaped frame 2 107. A clamping mechanism for use with the rolling roller 2 108 is provided on the U-shaped frame 2 107. A limiting mechanism for use with the U-shaped frame 2 107 is provided on the U-shaped frame 1 105. A drive mechanism 1 for use with the sliding seat 104 is provided inside the arc-shaped slide groove 103. A drive mechanism 2 for use with the built-in mold 102 is provided on the processing table 100. A positioning and clamping mechanism is provided on the processing table 100.
[0022] In the initial state, the built-in mold 102 is located inside the bending mold 101, and the U-shaped frame 107 is located away from the bending mold 101 to avoid affecting the placement of the slide rail body 700 to be bent.
[0023] In use, the slide rail body 700 to be bent is placed on the upper surface of the processing table 100. The bent mold 101 and positioning clamping mechanism clamp and position the placed slide rail body 700 to prevent displacement during bending. After the slide rail body 700 is placed, the drive mechanism 2 causes the inner mold 102 to extend from one side of the bent mold 101 (since the inner mold 102 is arc-shaped, after it extends from one side, part of the inner mold 102 moves to the inner surface of the slide rail body 700). Then, the U-shaped frame 107 is rotated 90° towards the bending mold 101. At this time, the limiting mechanism limits and fixes the U-shaped frame 107. The rolling roller 108 then rolls on the upper surface of the slide rail body 700, and then the clamping mechanism... Under the action of the roller, the second roller 108 applies a downward force. Then, the drive mechanism drives the sliding seat 104, the U-shaped frame 105, the first roller 106, the second U-shaped frame 107, and the second roller 108 to move together. During this process, the first roller 106, in conjunction with the bending die 101, processes one end of the slide rail body 700 into a bent shape. During this process, the second roller 108 moves and rolls on the upper surface of the slide rail body 700. In conjunction with the built-in die 102, it flattens the raised parts on the upper surface of the slide rail body 700 (the lower surface of the slide rail body 700 cannot produce a raised deformation due to the limitation of the upper end face of the processing table 100 and the lower end face of the built-in die 102). Then, the sliding seat 104, the first U-shaped frame 105, the first roller 106, the second U-shaped frame 107, and the second roller 108 return to their initial positions. Then, the bent slide rail body 700 is unloaded.
[0024] A rotating notch 200 is provided on the side wall of the U-shaped frame 105. A rotating plate 201 is rotatably arranged in the rotating notch 200. The U-shaped frame 207 is fixed to one end of the rotating plate 201. A handle 202 is fixed on one side of the U-shaped frame 207.
[0025] The handle 202 allows staff to easily adjust the positions of the U-shaped frame 2 107 and the rolling roller 2 108.
[0026] The limiting mechanism includes an electromagnet 203 located on one side of the rotating notch 200. A side groove 204 is provided on one side of the rotating plate 201, and an iron block 205 is fixed in the side groove 204. In the initial state, the electromagnet 203 is de-energized. A controller is provided on the processing table 100 to work with the electromagnet 203. The control of the electromagnet 203 on and off is existing technology.
[0027] In the initial state, the U-shaped frame 107 is positioned away from the bending mold 101 to avoid affecting the placement of the slide rail body 700 to be bent. After the slide rail body 700 to be processed is positioned, the operator uses the handle 202 to rotate the rotating plate 201, the U-shaped frame 107, and the rolling roller 108 90° toward the bending mold 101 until the iron block 205 is in contact with one side of the electromagnet 203. At this time, the electromagnet 203 is energized and attracts the iron block 205, thereby limiting and fixing the rotating plate 201 and the U-shaped frame 107. This allows the U-shaped frame 107 and the rolling roller 108 to move together with the U-shaped frame 105, causing the rolling roller 108 to roll the upper surface of the slide rail body 700. After the slide rail body 700 is bent, the U-shaped frame 105 drives the U-shaped frame 107 and the rolling roller 108 to return to their initial positions. Then, the electromagnet 203 is de-energized, releasing the attraction to the iron block 205. Then, the operator pushes the U-shaped frame 107 away from the bending mold 101 using the handle 202 to avoid affecting the subsequent unloading operation of the slide rail body 700.
[0028] The clamping mechanism includes two lifting slots 300 opened on the inner wall of the second U-shaped frame 107, and the same third U-shaped frame 301 is movably arranged between the two lifting slots 300. The second rolling roller 108 is rotatably arranged inside the third U-shaped frame 301. A hydraulic rod 302 is fixedly installed through the upper end face of the second U-shaped frame 107, and the end of the telescopic end of the hydraulic rod 302 is fixedly connected to the third U-shaped frame 301.
[0029] In the initial state, the telescopic end of the hydraulic rod 302 is in a retracted state. When the U-shaped frame 107 and the rolling roller 108 rotate to the upper surface of the slide rail body 700, the telescopic end of the hydraulic rod 302 extends, pushing the U-shaped frame 301 and the rolling roller 108 to move downward, so that the rolling roller 108 can apply a downward force to the slide rail body 700. As the U-shaped frame 107 and the rolling roller 108 move together with the U-shaped frame 105, the upper surface of the slide rail body 700 is rolled and trimmed.
[0030] The bending die 101 has a movable through groove 400 on its side wall, and the inner die 102 is movably disposed in the movable through groove 400.
[0031] The second drive mechanism includes two telescopic cylinders 401, which are symmetrically fixed in the movable through groove 400. The ends of the telescopic ends of the two telescopic cylinders 401 are fixed with the same mounting base 402, and the built-in mold 102 is fixed to one side of the mounting base 402.
[0032] In the initial state, the telescopic end of the telescopic cylinder 401 is in a retracted state, and both the mounting base 402 and the built-in mold 102 are in the movable through groove 400 to avoid affecting the positioning of the slide rail body 700 to be processed. After the slide rail body 700 is positioned, it is between the bending mold 101 and the first rolling roller 106. At this time, the telescopic end of the telescopic cylinder 401 extends, causing the mounting base 402 and the built-in mold 102 to move towards the slide rail body 700, so that the built-in mold 102 can cooperate with the second rolling roller 108 to trim the upper surface of the slide rail body 700. After the slide rail body 700 is bent, the telescopic end of the telescopic cylinder 401 retracts, and again moves the mounting base 402 and the built-in mold 102 into the movable through groove 400, so that the built-in mold 102 is demolded from the inner surface of the slide rail body 700, thus avoiding affecting the unloading operation of the slide rail body 700.
[0033] The positioning and clamping mechanism includes a positioning plate 500 disposed on one side of the bending mold 101, and two clamping cylinders 501 are symmetrically fixed on the upper end face of the processing table 100. The ends of the extension and retraction ends of the two clamping cylinders 501 are fixed with the same abutting plate 502.
[0034] In the initial state, the telescopic end of the clamping cylinder 501 is in a retracted state to prevent the contact plate 502 from affecting the placement of the slide rail body 700. After the slide rail body 700 to be processed is placed on the upper surface of the processing table 100, one end of the slide rail body 700 is forced to abut against one side of the positioning plate 500 to position the slide rail body 700. At this time, the slide rail body 700 is between the bending mold 101 and the rolling roller 106. Then, the telescopic end of the clamping cylinder 501 extends, pushing the contact plate 502 to abut against and press against one side of the slide rail body 700, thereby limiting and fixing the slide rail body 700 and preventing the slide rail body 700 from shifting during the bending process of the rolling roller 106.
[0035] A pusher cylinder 503 is fixed on the upper surface of the processing table 100, and the end of the telescopic end of the pusher cylinder 503 is fixedly connected to the positioning plate 500.
[0036] In the initial state, the telescopic end of the pusher cylinder 503 is in a retracted state, which, together with the positioning plate 500, positions the slide rail body 700. After the slide rail body 700 is positioned and bent into the required shape, the U-shaped frame 105, along with the rolling roller 106, U-shaped frame 2 107, and rolling roller 2 108, returns to the initial position. Then, the telescopic end of the pusher cylinder 503 extends, thereby pushing the bent slide rail body 700 to move. This causes the bent end of the slide rail body 700 to move away from the bending mold 101, making it easier for workers to pick up the slide rail body 700 and unload it.
[0037] The drive mechanism includes a mounting groove on one side of the sliding seat 104, in which a gear 600 is rotatably mounted. A drive box 601 that is used to rotate with the gear 600 is fixed on the upper end face of the sliding seat 104. An arc-shaped rack 602 is fixed on the inner wall of the arc-shaped slide groove 103. The gear 600 and the arc-shaped rack 602 are meshed and connected. A guide unit that is used with the sliding seat 104 is provided in the arc-shaped slide groove 103.
[0038] When the drive gear 600 of the drive box 601 rotates in the forward direction, under the action of the arc rack 602, the sliding seat 104, the U-shaped frame 105 and the rolling roller 106 are moved away from the pusher cylinder 503, so as to cooperate with the bending die 101 to bend the slide rail body 700 into the required shape. At this time, the drive box 601 can drive the gear 600 to rotate in the reverse direction, so as to reset the sliding seat 104, the U-shaped frame 105 and the rolling roller 106.
[0039] The guide unit includes two arc-shaped guide rails 603 fixed to the bottom of the arc-shaped slide groove 103. The arc-shaped guide rails 603 slide through the slide seat 104, and the slide seat 104 is slidably disposed on the two arc-shaped guide rails 603.
[0040] The sliding seat 104 is guided by the arc-shaped guide rail 603, which is part of the prior art.
[0041] In use, the built-in mold 102 is located inside the bending mold 101, and the U-shaped frame 107 is positioned away from the bending mold 101. The slide rail body 700 to be bent is then placed on the upper surface of the processing table 100. The bending mold 101 and the positioning and clamping mechanism clamp and position the placed slide rail body 700 to prevent displacement during bending. After the slide rail body 700 is placed, the driven mechanism 102 causes the built-in mold 102 to extend from one side of the bending mold 101 (since the built-in mold 102 is arc-shaped, after extending from one side, part of the built-in mold 102 moves to the inner surface of the slide rail body 700). Then, the U-shaped frame 107 is rotated 90° towards the bending mold 101. At this time, the limiting mechanism limits and fixes the U-shaped frame 107, and the rolling roller 108 rolls... The rollers press against the upper surface of the slide rail body 700. Then, under the action of the clamping mechanism, the second roller 108 applies a downward force. The drive mechanism then drives the sliding seat 104, U-shaped frame 105, roller 106, U-shaped frame 107, and roller 108 to move together. During this process, the first roller 106, in conjunction with the bending die 101, processes one end of the slide rail body 700 into a bent shape. Meanwhile, the second roller 108 moves and rolls against the slide rail. The upper surface of the slide rail body 700 is flattened by the built-in mold 102, where there are protrusions (the lower surface of the slide rail body 700 cannot be deformed due to the limitation of the upper end face of the processing table 100 and the lower end face of the built-in mold 102). Then the sliding seat 104, U-shaped frame 105, rolling roller 106, U-shaped frame 2 107 and rolling roller 2 108 are reset to their initial positions, and then the bent slide rail body 700 is cut into blanks. In the initial state, the telescopic end of the telescopic cylinder 401 is in a retracted state, and the mounting base 402 and the built-in mold 102 are both in the movable through groove 400 to avoid affecting the positioning of the slide rail body 700 to be processed. After the slide rail body 700 is positioned, the slide rail body 700 is between the bending mold 101 and the first rolling roller 106. At this time, the telescopic end of the telescopic cylinder 401 extends, causing the mounting base 402 and the built-in mold 102 to move towards the slide rail body 700, so that the built-in mold 102 can cooperate with the second rolling roller 108 to trim the upper surface of the slide rail body 700. After the slide rail body 700 is bent, the telescopic end of the telescopic cylinder 401 retracts, and once again drives the mounting base 402 and the built-in mold 102 to move into the movable through groove 400, so that the built-in mold 102 is demolded from the inner surface of the slide rail body 700 to avoid affecting the unloading operation of the slide rail body 700. In the initial state, the telescopic end of the clamping cylinder 501 is in a retracted state to prevent the contact plate 502 from affecting the placement of the slide rail body 700. After the slide rail body 700 to be processed is placed on the upper surface of the processing table 100, one end of the slide rail body 700 is forced to abut against one side of the positioning plate 500 to position the slide rail body 700. At this time, the slide rail body 700 is between the bending mold 101 and the rolling roller 106. Then, the telescopic end of the clamping cylinder 501 extends and pushes the contact plate 502 to abut against and press against one side of the slide rail body 700, thereby limiting and fixing the slide rail body 700 and preventing the slide rail body 700 from shifting during the bending process of the rolling roller 106. In the initial state, the telescopic end of the pusher cylinder 503 is in a retracted state, which, together with the positioning plate 500, positions the slide rail body 700. After the slide rail body 700 is positioned and bent into the required shape, the U-shaped frame 105, along with the rolling roller 106, U-shaped frame 2 107, and rolling roller 2 108, returns to the initial position. Then, the telescopic end of the pusher cylinder 503 extends, thereby pushing the bent slide rail body 700 to move. This causes the bent end of the slide rail body 700 to move away from the bending mold 101, making it easier for workers to pick up the slide rail body 700 and unload it.
[0042] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
