Description

Technical Field

[0001] This utility model relates to the field of auxiliary feeding technology, and in particular to an auxiliary feeding device for a CNC bending machine. Background Technology

[0002] Office furniture refers to furniture provided for the convenience of office workers in daily life, work, and social activities. The legs and other components of office furniture are made of metal. Due to the high hardness of metal, bending machines are needed to bend them into the required angles and curvatures. CNC bending machines use equipped dies to bend cold metal sheets into workpieces of various geometric cross-sectional shapes. In the production of office desks, bending machines are often used to bend the metal sheet legs, and auxiliary devices are used to facilitate the loading of the legs.

[0003] In the existing technology, since the plate support leg is made of square steel pipe, and since the square pipe has a wide side and a narrow side, only the narrow side of the square pipe needs to be bent during production. Common bending machines do not have corresponding correction devices, which makes it impossible to continuously bend the square pipe. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary feeding device for CNC bending machines, which has the advantages of position correction and surface cleaning, and solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an auxiliary feeding device for a CNC bending machine, comprising a machine body, a pad strip on the top of the machine body, a storage box fixedly installed on one side of the machine body, protective plates between the top two sides of the storage box and the pad strip, a sliding plate between the top side of the storage box and the pad strip, the top surface of the sliding plate being inclined, the sliding plate being located between the protective plates, a cylinder A fixedly installed on one side of the machine body below the storage box, a pusher fixedly connected to the output shaft end of the cylinder A inside the storage box, the top of the pusher being inclined, the angle between the top inclined surface of the pusher and the surface of the sliding plate being equal, a cylinder B fixedly installed at the top end of the pad strip, a sliding strip fixedly installed on the top of the pad strip on one side of the cylinder B, and a cleaning device fixedly installed on the top of the machine body at the other end of the pad strip.

[0006] With the above structural setup, the cylinder B and the sliding strip work together to correct the direction of the material at a certain angle. When the square tube material passes the correction arc plate, its outer surface comes into contact with and is squeezed against the upper surface of the correction arc plate, causing the angle of the material to change and the horizontal material to be corrected into a vertical material.

[0007] Preferably, the cylinder B is provided with a push block on the surface of the slide bar, the push block is fixedly connected to the end of the output shaft of the cylinder B, and the outer surface of the push block is in contact with the inner surface of the slide bar.

[0008] With the above-described structure, when the pusher block is pushed out by the output shaft of cylinder B, it will push the material to move in the direction of the cleaning device.

[0009] Preferably, the sliding strip is divided into three sections, wherein the head has an L-shaped cross-section and its inner surface is in contact with the outer surface of the push block, the tail has a U-shaped cross-section and its internal dimensions are adapted to the material dimensions, the middle section of the sliding strip is a correction section, and a correction arc plate is provided between the head end and the tail end of the sliding strip.

[0010] With the above structural setup, the sliding strip mainly plays an auxiliary corrective role during operation. The cylinder B pushes the material towards the cleaning device through the operation of its output shaft. When the material passes the corrective arc plate, a relative force is generated between its surface and the surface of the corrective arc plate, and the angle of the material changes, changing it from a horizontal angle to a vertical angle.

[0011] Preferably, the cleaning device includes a motor, a brush roller, and a transmission gear. The cleaning device has a drive groove inside, and brush grooves are evenly distributed above the drive groove inside the cleaning device. A transmission groove is distributed at the connection of the brush grooves inside the cleaning device. The motor is fixedly installed inside the drive groove. The brush roller is rotatably installed inside the brush groove of the cleaning device. The outer ring of the brush roller is provided with bristles, and the end of the brush roller is provided with a transmission gear.

[0012] With the above-mentioned structure, the brush rollers are driven to rotate by the motor, and the brush rollers are driven by transmission gears to sweep away the impurities on the surface of the material towards the direction of the material strip, so that the surface of the material is clean when it is bent.

[0013] Preferably, the brush roller assembly comprises four rollers, including a left long roller, an upper short roller, a right long roller, and a lower short roller. The bottom of the left long roller is connected to the output shaft of the motor via a coupling. A bevel gear A is provided at the top of the left long roller, bevel gears B are provided on both sides of the upper short roller, bevel gears A are provided at the top and bottom of the right long roller, and bevel gear B is provided on one side of the lower short roller. The bevel gears A and B mesh with each other.

[0014] With the above structural configuration, the motor's output shaft drives the left long roller to rotate via a coupling. The left long roller drives the upper short roller to rotate via the meshing of bevel gears A and B. The upper short roller transmits power to the right long roller via the meshing of bevel gears B and A. When the right long roller rotates, it drives the lower short roller to rotate via bevel gears A and B.

[0015] This utility model has the following advantages:

[0016] 1. The auxiliary feeding device of this CNC bending machine corrects the material angle by setting up a storage box, cylinder B, and a sliding strip. The material is uniformly placed into the storage box and slides to the top of the pusher frame through the inclined surface at the bottom of the storage box. Then, cylinder A is activated. Cylinder A controls the extension and retraction of the output shaft, causing the pusher frame to move the material upward. After the pusher frame moves to the top, the bottom of the material slides smoothly along the top surface of the pusher frame and the surface of the sliding plate to the inner surface of the head of the sliding strip. Then, cylinder B is activated. Cylinder B controls the extension of the output shaft, causing the surface of the pusher block to push the material towards the cleaning device. When the material passes the correction arc plate, a relative force is generated between its surface and the surface of the correction arc plate. Since the position of the correction arc plate is fixed, the angle of the material changes from a horizontal angle to a vertical angle, thus correcting the angle of the material.

[0017] 2. The auxiliary feeding device of this CNC bending machine cleans the surface of the material by setting up a cleaning device, brush rollers, transmission gears, etc. The material enters the tail section of the sliding strip, making the material match the tail section of the sliding strip. Then, the sliding strip slides into the interior of the cleaning device by being pushed by the push block. Then, the motor is started, and the output shaft of the motor drives the brush rollers to rotate through the coupling. The brush rollers work synchronously through the transmission gears, so that the material is cleaned by the bristles on the surface of the brush rollers when it passes through the interior of the cleaning device, which achieves the effect of cleaning the material.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-2 An auxiliary feeding device for a CNC bending machine includes a machine body 1. A pad strip 11 is provided on the top of the machine body 1. A storage box 2 is fixedly installed on one side of the machine body 1. A guard plate 21 is provided between the top two sides of the storage box 2 and the pad strip 11. A slide plate 22 is provided between the top one side of the storage box 2 and the pad strip 11. The top surface of the slide plate 22 is inclined. The slide plate 22 is located between the guard plates 21. A cylinder A3 is fixedly installed on one side of the machine body 1 below the storage box 2. A pusher 31 is fixedly connected to the end of the output shaft of the cylinder A3 inside the storage box 2. The top of the pusher 31 is inclined. The angle between the top inclined surface of the pusher 31 and the surface of the slide plate 22 is equal. A cylinder B4 is fixedly installed at the top end of the pad strip 11. A sliding strip 5 is fixedly installed on the top side of the pad strip 11 and the other end of the pad strip 11 is fixedly installed on the top of the machine body 1.

[0025] In actual operation, the materials are stored inside the storage box 2. When the cylinder A3 is working, it lowers the position of the pusher 31 by retracting the output shaft, so that the material slides through the inclined surface at the bottom of the storage box 2 to the top of the pusher 31. Then, the cylinder A3 controls the position of the pusher 31 to rise. When the material reaches the top of the storage box 2 after being lifted by the pusher 31, it slides through the surface of the slide plate 22 into the inside of the sliding strip 5. Then, it works in conjunction with the cylinder B4 and the sliding strip 5 to realize automatic feeding while correcting the angle of the material.

[0026] In practical applications, this device uses a combination of cylinder B4 and sliding strip 5 to correct the orientation of the material at a certain angle. After the square tube material slides to the inner surface of the sliding strip 5 via the slide plate 22, it is pushed by the push block 41 driven by cylinder B4. When the material passes through the correction arc plate 51, its outer surface contacts and is pressed against the upper surface of the correction arc plate 51, causing the angle of the material to change. After passing through the correction arc plate 51, the horizontally placed material is corrected into a vertical material, which facilitates subsequent processing of the material.

[0027] Please see Figures 1-2 The cylinder B4 is provided with a push block 41 on the surface of the slide bar 5. The push block 41 is fixedly connected to the end of the output shaft of the cylinder B4, and the outer surface of the push block 41 is in contact with the inner surface of the slide bar 5.

[0028] The cylinder B4 controls the position of the push block 41 inside the sliding strip 5 by controlling the extension and retraction of the output shaft. When the push block 41 is pushed out by the output shaft of the cylinder B4, it will push the material to move towards the cleaning device 6.

[0029] Please see Figures 1-2 The sliding strip 5 is divided into three sections. The head section has an L-shaped cross-section, and its inner surface is in contact with the outer surface of the push block 41. The tail section of the sliding strip 5 has a U-shaped cross-section, and its internal dimensions are adapted to the material dimensions. The middle section of the sliding strip 5 is the correction section. A correction arc plate 51 is provided between the head end and the tail end of the sliding strip 5. One side of the correction arc plate 51 is a horizontal rectangle and is connected to the head. The other side of the correction arc plate 51 is a vertical rectangle and is connected to the tail.

[0030] When the material slide bar 5 is working, it mainly plays an auxiliary correction role. The cylinder B4 pushes the material towards the cleaning device 6 through the operation of its output shaft. When the material passes the correction arc plate 51, a relative force is generated between its surface and the surface of the correction arc plate 51. Since the position of the correction arc plate 51 is fixed, the angle of the material will change from a horizontal angle to a vertical angle and enter the tail section of the material slide bar 5, so that the material matches the tail section of the material slide bar 5 and corrects the angle of the material.

[0031] Please see Figures 1-4 The cleaning device 6 includes a motor 64, a brush roller 65, and a transmission gear 66. The cleaning device 6 has a drive groove 61 inside, and brush grooves 62 are evenly distributed above the drive groove 61 inside the cleaning device 6. A transmission groove 63 is provided at the connection of the brush grooves 62 inside the cleaning device 6. The motor 64 is fixedly installed inside the drive groove 61. The brush roller 65 is rotatably installed inside the brush groove 62 of the cleaning device 6. The outer ring of the brush roller 65 is provided with bristles, and the end of the brush roller 65 is provided with a transmission gear 66.

[0032] When the cleaning device 6 is working, the brush roller 65 is driven to rotate by the motor 64. The brush rollers 65 are driven by the transmission gear 66. The rotation direction of the brush roller 65 is opposite to the sliding direction of the material. When working, the brush roller 65 rotates clockwise to sweep away the impurities on the surface of the material towards the starting direction of the sliding strip 5, so that the surface of the material is clean when it is bent.

[0033] Please see Figures 1-4The brush roller 65 consists of four parts: a left long roller, an upper short roller, a right long roller, and a lower short roller. The bottom of the left long roller is connected to the output shaft of the motor 64 via a coupling. A bevel gear A661 is located at the top of the left long roller, and bevel gears B662 are located on both sides of the upper short roller. A bevel gear A661 is located at the top and bottom of the right long roller, and a bevel gear B662 is located on one side of the lower short roller. Bevel gears A661 and B662 mesh with each other. The left long roller is connected to the upper short roller via bevel gears A661 and B662. The upper short roller is connected to the right long roller via bevel gears B662 and A661. The right long roller is connected to the lower short roller via bevel gears A661 and B662.

[0034] The output shaft of motor 64 drives the left long roller to rotate through a coupling. The left long roller drives the upper short roller to rotate through the meshing between bevel gears A661 and B662. The upper short roller drives the right long roller through the meshing between bevel gears B662 and A661. When the right long roller rotates, it drives the lower short roller to rotate through bevel gears A661 and B662, so that the brush roller 65 can brush away impurities from the surface of the material.

[0035] Working principle: During operation, materials are uniformly placed inside the storage bin 2. The materials slide along the inclined surface at the bottom of the storage bin 2 to the top of the pusher 31. Then, cylinder A3 is activated. Cylinder A3 controls the extension and retraction of the output shaft, causing the pusher 31 to move the materials upward. After the pusher 31 moves to the top, the bottom of the materials slides smoothly along the top surface of the pusher 31 and the surface of the slide plate 22 to the inner surface of the head of the sliding strip 5. Then, cylinder B4 is activated. Cylinder B4 controls the extension of the output shaft, causing the surface of the pusher block 41 to push the materials towards the cleaning device 6. When the materials pass the correcting arc plate 51, their surface and the surface of the correcting arc plate 51 are... The relative force generated between the material and the fixed position of the correcting arc plate 51 will change the angle of the material from a horizontal angle to a vertical angle, and the material will enter the tail section of the sliding strip 5, so that the material and the tail section of the sliding strip 5 are matched. Then the sliding strip 5 is pushed into the interior of the cleaning device 6 by the push block 41. Then the motor 64 is started, and the output shaft of the motor 64 drives the brush roller 65 to rotate through the coupling. The brush rollers 65 are driven by the transmission gear 66 to achieve synchronous operation, so that the material is cleaned by the bristles on the surface of the brush roller 65 when it passes through the interior of the cleaning device 6, making the surface of the material clean and free of impurities, which is convenient for subsequent bending and other work.
