Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically relating to a splitting feeding device for an automatic integrated machine for forming chipless short U-shaped collars. Background Technology

[0002] Existing automatic short U-shaped collar forming machines require sequential steps of cutting, flaring, bending, cleaning, degreasing, and collar forming at a cutting machine, flaring machine, bending machine, cleaning machine, and collar forming machine. This process is cumbersome, inconvenient to operate, and results in high labor costs. To address these technical issues, our company designed a patent with application number CN201510458729.8 and patent title: "Cutting Head and its Stacked Automatic Short U-Shaped Collar Forming Machine." While this patent solves the aforementioned technical problems, the short U-shaped collar forming machine, after being cut by the cutting unit... In the flaring machine, the incompletely cut portion is pulled off and flared by moving the clamped position to the left during the flaring process. After that, the short pipe is released and falls into the bending machine, and then pushed into the bending station by the pushing mechanism. However, in actual production, it was found that because the incompletely cut portion is pulled off by clamping both ends of the cutting position and then moving the flaring machine horizontally to the left, wear on the mold clamping position can lead to insufficient clamping force, causing slippage and failure to pull off the cut. This results in the inability to connect the various processes in an orderly manner, affecting production efficiency. Therefore, it is necessary to improve the above-mentioned problems. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a cutting and feeding device for an automatic forming machine for chipless short U-shaped collars. This device uses a first and second chuck assembly, driven by two small cylinders moving in opposite directions below a lifting plate, to stably clamp the short pipe before and after cutting. A lifting device then moves the lifting plate, the first chuck assembly, and the second chuck assembly up and down, using the shearing force during downward movement to reliably cut and feed the incompletely cut portion of the short pipe. This avoids the problem of insufficient clamping force during horizontal movement caused by mold wear, which leads to pipe slippage and breakage in the original structure. It ensures orderly connection between processes, guarantees production progress, and eliminates gaps between processes by simultaneously cutting and feeding the short pipe downwards, thus improving production continuity.

[0004] The technical solution adopted in this utility model is a cutting and feeding device for an automatic forming machine for chipless short U-shaped collars. It includes a lifting plate parallel to the width of the base plate and located on the discharge side of the cutting unit. A first clamping group and a second clamping group, mutually cooperating, are installed at the bottom of the lifting plate via guide components. Two small cylinders are symmetrically fixed to the upper surface of the lifting plate, and the telescopic ends of the two cylinders are fixedly connected to the first and second clamping groups via connecting plates that pass through guide holes at corresponding positions on the lifting plate surface. The two small cylinders drive the first and second clamping groups to move in opposite directions, clamping or releasing the short tube. Both ends of the lifting plate are supported on the base plate by lifting devices. The short tube, after being cut by the cutting unit, is clamped and moved downwards by the first and second clamping groups driven by the lifting device, thus achieving short tube displacement, cutting, and downward feeding.

[0005] The first and second chuck groups are each provided with a limit adjustment device on the outer side of both ends, which is installed on the bottom surface of the lifting plate and is used to adjust and limit the outward movement of the first and second chuck groups.

[0006] Furthermore, the limiting adjustment device includes limiting bolts. Two mounting vertical plates are symmetrically fixed on the bottom surface of the lifting plate, and the first clamp group and the second clamp group are located between the two mounting vertical plates. The limiting bolts with their large ends facing outwards are adapted to be connected to the threaded holes on the surface of the mounting vertical plates. The distance between the two ends of the first clamp group and the second clamp group and the small ends of the corresponding limiting bolts is adjusted by rotating the corresponding limiting bolts. The outer side of the mounting vertical plates is provided with locking nuts adapted to be connected to the limiting bolts and used to lock and fix the limiting bolts in place when their positions are adjusted.

[0007] Furthermore, the guide assembly includes a slider bearing and a guide rail. Multiple slider bearings are fixed on the bottom surface of the lifting plate, and the guide rail is adapted to the multiple slider bearings. The upper ends of the first chuck group and the second chuck group are respectively fixedly connected to the guide rail in the guide assembly at the corresponding positions.

[0008] Furthermore, both the first and second chuck groups include a mounting plate and clamping plates. The mounting plate is fixed to the bottom of the guide rail in the guide assembly, and the upper ends of multiple clamping plates are fixed to the bottom of the mounting plate. The lower ends of the clamping plates in the first and second chuck groups have corresponding arc-shaped grooves on their facing sides. The lower ends of the two connecting plates are fixedly connected to the mounting plates in the first and second chuck groups, respectively. When the first and second chuck groups move towards or away from each other under the drive of two small cylinders, the two clamping plates clamp or release the short pipe located in the arc-shaped groove.

[0009] Furthermore, the clamping plate in the first clamping assembly has an L-shaped plate structure, and the horizontal plate at the upper end of the clamping plate extends outward along the thickness direction of its vertical plate. The clamping plate in the second clamping assembly includes an L-shaped plate and a fixing plate fixed to the outer end of the horizontal plate at the upper end of the L-shaped plate. The horizontal plate at the upper end of the clamping plate extends outward along the width direction of its vertical plate. The fixing plate of the clamping plate in the second clamping assembly is fixedly connected to the corresponding mounting plate.

[0010] Furthermore, the lifting device includes a large atmospheric cylinder, the lower end of which is fixed to the base plate via a cylinder seat, and the telescopic part of the upper end of the atmospheric cylinder is fixedly connected to the corresponding end of the lifting plate, thereby realizing the up and down lifting of the lifting plate under the telescopic control of the atmospheric cylinder.

[0011] Furthermore, a guide rod located outside the atmospheric cylinder and passing through the guide hole on the corresponding end plate of the lifting plate is also fixed on the cylinder seat.

[0012] Furthermore, the two ends of the small cylinder body are fixed to the lifting plate by L-shaped plates.

[0013] Advantages of this utility model compared to the prior art: 1. This technical solution uses a first chuck group and a second chuck group, driven by two small cylinders to move in opposite directions, to stably clamp the short pipe before and after cutting by setting a first chuck group and a second chuck group below the lifting plate. Then, the lifting device drives the lifting plate and the first chuck group and the second chuck group to move up and down, so as to reliably cut off the incompletely cut part of the short pipe by using the shearing force during the downward movement and move it down for feeding. This avoids the problem of pipe slippage and breakage caused by insufficient clamping force during horizontal movement due to mold wear in the original structure. It ensures the orderly connection of each process and guarantees the production progress. 2. This technical solution optimizes the short pipe cutting and feeding method, enabling the short pipe to be cut and fed simultaneously, eliminating gaps between processes and improving production continuity; 3. This technical solution allows for adjustment of the distance between the small end of the rotating limiting bolt and the two ends of the first and second clamping groups, enabling precise control of the outward movement of the two clamping plates. Under the premise of ensuring reliable clamping of the short pipe, the short pipe can be smoothly released with minimal outward movement, adapting to the use of short pipes of different diameters. There is no need to replace the overall structure of the clamping group, improving the versatility and applicability of the device and reducing equipment replacement and maintenance costs. 4. This technical solution has a simple structure, novel design, compact structure, good stability, and tight process connection, which is conducive to improving the production efficiency of short U-rings, reducing equipment maintenance costs and replacement costs of vulnerable parts, and has high application value.

[0018] A chip-free short U-shaped collar automatic forming integrated machine uses a segmented feeding device, such as... Figure 1-5As shown, the device includes a lifting plate 2 parallel to the width of the base plate 1 and located on the discharge side of the cutting unit. A first chuck assembly 3 and a second chuck assembly 4, which cooperate with each other, are mounted on the bottom of the lifting plate 2 via guide components. Two small cylinders 5 are symmetrically fixed to the upper surface of the lifting plate 2. The cylinder bodies of the small cylinders 5 are fixed to the lifting plate 2 at both ends via L-shaped plates 15. The telescopic ends of the two small cylinders 5 are fixedly connected to the first chuck assembly 3 and the second chuck assembly 4 via connecting plates 6 that pass through guide holes 7 at corresponding positions on the surface of the lifting plate 2. The short pipe is clamped or released when the two small cylinders 5 drive the first chuck assembly 3 and the second chuck assembly 4 to move in opposite directions. The two ends of the lifting plate 2 are supported by lifting devices. On the base plate 1, the short pipe that has been cut by the cutting component is clamped and moved downward by the lifting device, which drives the first clamp group 3 and the second clamp group 4 to realize the short pipe displacement, cutting and downward feeding. In the above structure, by setting the first clamp group 3 and the second clamp group 4 below the lifting plate 2 and driving them to move in opposite directions by two small cylinders 5, the short pipe before and after cutting is stably clamped. Then, the lifting device drives the lifting plate 2 and the first clamp group 3 and the second clamp group 4 to move up and down, so as to realize the reliable cutting and downward feeding of the incompletely cut part of the short pipe by using the shearing force during downward movement. This avoids the problem of pipe slippage and breakage caused by insufficient clamping force during horizontal movement due to mold wear in the original structure, ensuring the orderly connection of each process and guaranteeing the production progress. Optimize the short pipe cutting and feeding method to achieve simultaneous short pipe downward cutting and downward feeding, eliminate process connection gaps, and improve production continuity; To meet the limiting requirements for the outward movement of the first chuck assembly 3 and the second chuck assembly 4 when clamping short pipes of different diameters, a limiting adjustment device is provided on the outer sides of both ends of the first chuck assembly 3 and the second chuck assembly 4, mounted on the bottom surface of the lifting plate 2, for adjusting and limiting the outward movement of the first chuck assembly 3 and the second chuck assembly 4. Specifically, the limiting adjustment device includes a limiting bolt 8, and two mounting vertical plates 9 are symmetrically fixed on the bottom surface of the lifting plate 2, with the first chuck assembly 3 and the second chuck assembly 4 located between the two mounting vertical plates 9. The limiting bolt 8, with its larger end facing outward, is adapted to connect with the threaded hole on the surface of the mounting vertical plate 9, and the distance between the two ends of the first chuck assembly 3 and the second chuck assembly 4 is... The distance between the small ends of the corresponding limiting bolts 8 is adjusted by rotating the corresponding limiting bolts 8. The outer side of the mounting vertical plate 9 is provided with a locking nut 10 that is adapted to be connected to the limiting bolts 8 and used to lock and fix the limiting bolts 8 in the position adjustment. In the above structure, the distance between the small end of the limiting bolt 8 and the two ends of the first clamp group 3 and the second clamp group 4 can be adjusted by rotating the limiting bolts 8. The outward movement of the two clamping plates 14 can be precisely controlled. Under the premise of ensuring reliable clamping of the short pipe, the short pipe can be released smoothly with the minimum outward movement. It is suitable for use with short pipes of different diameters. There is no need to replace the overall structure of the clamping group, which improves the versatility and applicability of the device and reduces the cost of equipment replacement and maintenance. The specific structure of the guide assembly is as follows: The guide assembly includes a slider bearing 11 and a guide rail 12. Multiple slider bearings 11 are fixed to the bottom surface of the lifting plate 2, and the guide rail 12 is adapted to the multiple slider bearings 11. The upper ends of the first chuck group 3 and the second chuck group 4 are respectively fixedly connected to the guide rail 12 in the corresponding position of the guide assembly. The slider bearing 11 and the guide rail 12 are adapted to provide precise guidance for the movement of the first chuck group 3 and the second chuck group 4, effectively avoiding problems such as offset and jamming during the movement of the first chuck group 3 and the second chuck group 4 towards or in opposite directions. This ensures that the first chuck group 3 and the second chuck group 4 always move smoothly along the preset trajectory, thereby ensuring accurate clamping of the short pipe and improving the stability of short pipe clamping and subsequent transfer.

[0019] The specific structures of the first chuck assembly 3 and the second chuck assembly 4 are as follows: Both the first chuck assembly 3 and the second chuck assembly 4 include a mounting plate 13 and clamping plates 14. The mounting plate 13 is fixed to the bottom of the guide rail 12 in the guide assembly, and the upper ends of multiple clamping plates 14 are fixed to the bottom of the mounting plate 13. The lower ends of the clamping plates 14 in the first chuck assembly 3 and the second chuck assembly 4 have corresponding arc-shaped grooves 16 on their facing sides. The lower ends of the two connecting plates 6 are respectively fixedly connected to the mounting plates 13 in the first chuck assembly 3 and the second chuck assembly 4. When the chuck assembly 4 moves towards or away from each other under the drive of the two small cylinders 5, the two clamping plates 14 clamp or release the short tube located in the arc-shaped long groove 16. The arc-shaped long groove 16 is designed to fit the outer wall of the short tube during clamping and achieve stable clamping, preventing the short tube from shifting or slipping during clamping or transfer. The two clamping plates 14 are connected to the telescopic ends of the small cylinders 5 through the connecting plates 6, and can accurately move towards or away from each other under the drive of the small cylinders 5. The clamping force can be controlled by adjusting the telescopic amount of the small cylinders 5 to avoid the short tube from deforming due to excessive clamping force or slipping due to insufficient clamping force.

[0020] In the first clamping assembly 3, the clamping plate 14 has an L-shaped plate structure, and the horizontal plate at the upper end of the clamping plate 14 extends outward along the thickness direction of its vertical plate. The clamping plate 14 in the second clamping assembly 4 includes an L-shaped plate and a fixing plate fixed to the outer end of the upper horizontal plate of the L-shaped plate. The horizontal plate at the upper end of the clamping plate 14 extends outward along the width direction of its vertical plate. The fixing plate of the clamping plate 14 in the second clamping assembly 4 is fixedly connected to the corresponding mounting long plate 13.

[0021] The specific structure of the lifting device is as follows: The lifting device includes a large air cylinder 17. The lower end of the large air cylinder 17 is fixed to the base plate 1 through a cylinder seat 18, and the telescopic part of the upper end of the large air cylinder 17 is fixedly connected to the corresponding end of the lifting plate 2. Under the telescopic control of the large air cylinder 17, the lifting plate 2 can be lifted up and down. Specifically, a guide rod 19 located outside the large air cylinder 17 and passing through the guide hole on the corresponding end plate surface of the lifting plate 2 is also fixed on the cylinder seat 18. This ensures the stability of the first clamp group 3 and the second clamp group 4 when clamping and moving the short pipe downward, so as to realize the short pipe displacement, cutting and downward feeding.

[0022] This technical solution features a simple structure, novel design, compact structure, good stability, and tight process connections. It is conducive to improving the production efficiency of short U-rings, reducing equipment maintenance costs and replacement costs of vulnerable parts, and has high application value.
