Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bending machines, in particular to a numerical control bending machine with auxiliary positioning function. BACKGROUND

[0002] A bending machine is a device for bending a plate, which can bend a plate once. Sometimes, the plate needs to be bent twice. Some bending machines use a manual positioning method for plate positioning, which takes a long time. When bending the plate, a bending die is generally used for bending, and the bending angle is generally fixed.

[0003] The defects of the existing bending machine are:

[0004] 1. The prior art KR1020170067596A discloses a material bending machine. The technology discloses a bending machine capable of easily replacing a new beam of a new die in an upper part of a lower die body and an upper die body of the material bending machine. The bending machine does not have a structure for automatically positioning the material, and the worker needs to manually position it. The positioning process is troublesome, so a numerical control bending machine with auxiliary positioning function that can automatically position the plate is needed to solve this problem.

[0005] 2. The prior art KR101632458B1 discloses a bending machine. The technology does not have a structure for bending the plate according to the required bending angle, and cannot accurately bend the plate at different angles. Therefore, a numerical control bending machine with auxiliary positioning function that can accurately bend the plate at different angles is needed to solve this problem.

[0006] 3. The prior art KR1020130060374A discloses a bending machine. The technology produces a forced bending member with high productivity and excellent dimensional accuracy. When bending the plate twice, the plate needs to be removed and repositioned, which reduces the bending efficiency. Therefore, a numerical control bending machine with auxiliary positioning function that can easily position the plate for secondary bending is needed to solve this problem.

[0007] 4. The prior art CN113828673B discloses a bending machine. The technology solves the problem of high bending failure rate of the existing bending machine. After the bending machine finishes bending, the worker needs to manually remove the plate, which is labor-intensive.

[0019] S1, place the plate above the bending support plate, then drive the push plate to move backward through the hydraulic telescopic unit five, the push plate pushes the plate to the rear contact limiting plate, then measures the distance between the limiting plate and itself through the laser ranging unit one, then drives the limiting plate to move forward and backward through the hydraulic telescopic unit three, and the limiting plate and the push plate move forward and backward to move the plate to a suitable position, so that the specific position of the plate can be conveniently bent;

[0020] S2. Then, the bending plate is moved downward by the hydraulic telescopic unit one. The bending plate presses down and fixes the plate on the bending support plate by moving downward. Then, the rotating support plate is moved upward by the hydraulic telescopic unit four. The rotating support plate supports the bending support plate by moving upward, and at the same time, the bending support plate is lifted and rotated upward. The upward rotation of the bending support plate can bend the plate.

Then, the hydraulic telescopic unit 2 drives the bending plate to move downward. The bending plate can perform a secondary bending of the board by moving downward, thereby realizing continuous bending of the board.

[0023] Preferably, step S4 further includes the following steps:

[0024] S41: At the same time, the pressure sensing unit detects the pressure of the clamping plate on the plate. After the pressure of the clamping plate on the plate reaches the set value, the hydraulic telescopic unit seven stops working.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. In this invention, the sheet material is placed above the bending support plate. Then, the hydraulic telescopic unit five drives the push plate to move backward, pushing the sheet material to contact the limiting plate. Subsequently, the hydraulic telescopic unit three drives the limiting plate to move back and forth. The limiting plate and the push plate move back and forth in coordination, allowing the sheet material to move to the appropriate position. The laser ranging unit one measures the distance between the limiting plate and itself, which facilitates obtaining the position information of the sheet material. This allows for convenient bending of the sheet material at specific positions. The CNC bending machine with auxiliary positioning function can use the laser ranging unit one to measure the distance between the limiting plate and itself to obtain the position information of the sheet material, thus facilitating the bending of the sheet material at specific positions.

[0027] 2. This invention uses a hydraulic telescopic unit to move the bending plate downwards, which presses down on the sheet metal on the bending support plate. Then, a hydraulic telescopic unit four moves the rotating support plate upwards, supporting the bending support plate and simultaneously lifting it to rotate. This upward rotation of the bending support plate bends the sheet metal. An angle sensing unit detects the rotation angle of the bending support plate, facilitating bending of the sheet metal to the desired angle. This allows a CNC bending machine with auxiliary positioning function to use the hydraulic telescopic unit one to move the bending plate downwards to press down on the bending support plate, and then the hydraulic telescopic unit four to move the rotating support plate upwards, supporting the bending support plate and thus bending the sheet metal to the desired angle.

[0028] 3. In this invention, an electric telescopic unit drives a movable support rod to move forward. Then, a laser ranging unit 2 detects its distance from the rotating rod 1 until the distance between the laser ranging unit 2 and the rotating rod 1 reaches a set value. Then, a hydraulic telescopic unit 2 drives a bending plate to move downward. The bending plate can perform a secondary bend on the sheet material by moving downward, thereby achieving continuous bending of the sheet material. This allows a CNC bending machine with auxiliary positioning function to use the movable support rod to position and support the sheet material after the first bend at the position where a secondary bend is needed. Then, the bending plate can perform a secondary bend on the sheet material, making the secondary bending of the sheet material more convenient.

[0029] 4. In this invention, the clamping plate is moved inward by the hydraulic telescopic unit seven to clamp and fix the sheet metal. Then, the bending plate is moved upward by the hydraulic telescopic unit one, the pressure bending plate is moved upward by the hydraulic telescopic unit two, and the rotating support plate is moved downward by the hydraulic telescopic unit four. Subsequently, the clamping plate is moved backward by the hydraulic telescopic unit six, thereby causing the bent sheet metal to move backward and leave the bending seat, thus realizing the discharge of the sheet metal. This invention enables a CNC bending machine with auxiliary positioning function to clamp and fix the sheet metal by moving the clamping plate inward by the hydraulic telescopic unit seven, and then moving the clamping plate backward by the hydraulic telescopic unit six, thereby causing the bent sheet metal to move backward and leave the bending seat, thus realizing the discharge of the sheet metal.

[0054] The operating method of a CNC bending machine with auxiliary positioning function is as follows:

[0055] S1. Place the sheet material above the bending support plate 15, and then drive the push plate 28 to move backward through the hydraulic telescopic unit 27. The push plate 28 pushes the sheet material to contact the limiting plate 12. Then, the laser ranging unit 10 measures the distance between the limiting plate 12 and itself. Subsequently, the hydraulic telescopic unit 3 11 drives the limiting plate 12 to move back and forth. The limiting plate 12 and the push plate 28 move back and forth in coordination to move the sheet material to the appropriate position, so that it is convenient to bend the sheet material at a specific position.

[0056] S2. Then, the bending plate 5 is moved downward by the hydraulic telescopic unit 4. The bending plate 5 presses down and fixes the plate on the bending support plate 15 by moving downward. Then, the rotating support plate 25 is moved upward by the hydraulic telescopic unit 21. The rotating support plate 25 supports the bending support plate 15 by moving upward, and at the same time, the bending support plate 15 is lifted and rotated upward. The upward rotation of the bending support plate 15 can bend the plate. The angle sensing unit 16 can detect the rotation angle of the bending support plate 15, so that the bending angle of the plate can be easily obtained. After the bending angle reaches the set value, the hydraulic telescopic unit 21 stops working.

[0057] S3. When it is necessary to perform a secondary bending of the board, the electric telescopic unit 18 can drive the moving support rod 19 to move forward. Then, the laser ranging unit 20 detects its distance from the rotating rod 14 until the distance between the laser ranging unit 20 and the rotating rod 14 reaches the set value. Then, the hydraulic telescopic unit 6 drives the bending plate 7 to move downward. The bending plate 7 can perform a secondary bending of the board by moving downward, thereby realizing continuous bending of the board.

[0058] S4. Then, the clamping plate 34 is moved inward by the hydraulic telescopic unit 7 32 to clamp and fix the plate. Then, the hydraulic telescopic unit 1 4 moves the bending plate 5 upward, the hydraulic telescopic unit 2 6 moves the bending plate 7 upward, the hydraulic telescopic unit 4 21 moves the rotating support plate 25 downward, and then the hydraulic telescopic unit 6 30 moves the clamping plate 34 backward, so that the bent plate moves backward and leaves the bending seat 1, realizing the discharge of the plate.

[0059] S4 also includes the following steps:

[0060] S41: At the same time, the pressure sensing unit 33 detects the pressure of the clamping plate 34 on the plate. After the pressure of the clamping plate 34 on the plate reaches the set value, the hydraulic telescopic unit 32 stops working.

[0061] Working Principle: Before using a CNC bending machine with auxiliary positioning function, check whether there are any problems affecting its use. Place the sheet metal above the bending support plate 15. Then, the hydraulic telescopic unit 27 drives the push plate 28 to move backward. The push plate 28 pushes the sheet metal backward to contact the limiting plate 12. Then, the laser ranging unit 10 measures the distance between the limiting plate 12 and itself. Subsequently, the hydraulic telescopic unit 11 drives the limiting plate 12 to move back and forth. The limiting plate 12 and the push plate 28 move back and forth in coordination to move the sheet metal to the appropriate position. This allows for convenient bending of specific locations on the sheet material. The hydraulic telescopic unit 4 moves the bending plate 5 downwards, pressing and fixing the sheet material on the bending support plate 15. Then, the hydraulic telescopic unit 21 moves the rotating support plate 25 upwards, supporting the bending support plate 15 and simultaneously causing it to rotate upwards. This upward rotation of the bending support plate 15 allows for bending of the sheet material. The angle sensing unit 16 detects the rotation angle of the bending support plate 15, thus facilitating the determination of the sheet material's bending angle. The material is bent at a set angle. Once the bending angle reaches the set value, the hydraulic telescopic unit 21 stops working. When a secondary bending of the material is required, the electric telescopic unit 18 can drive the moving support rod 19 forward. Then, the laser ranging unit 20 detects its distance from the rotating rod 14 until the distance between the laser ranging unit 20 and the rotating rod 14 reaches the set value. Then, the hydraulic telescopic unit 6 drives the bending plate 7 downward. The bending plate 7 can perform a secondary bending of the material by moving downward, thereby achieving continuous bending of the material. Subsequently, the hydraulic telescopic unit 21... Unit 7 32 moves the clamping plate 34 inward to clamp and fix the plate. At the same time, the pressure sensing unit 33 detects the pressure of the clamping plate 34 on the plate.
