Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe cutting technology, specifically to a stainless steel pipe cutting device with continuous double-end chamfering. Background Technology

[0002] Stainless steel pipes are typically quite long, requiring the pipe to be fixed in place before being cut to the required length using a cutting machine. Cutting a large quantity increases the operator's physical strain and also lowers safety standards during the process.

[0003] Chinese patent CN220838176U discloses a stainless steel pipe cutting device, including a working plate. Support legs are fixed at the four corners of the bottom of the working plate, and a cutting groove is formed on the top surface. A cutting machine is also mounted on the top surface of the working plate, with its cutting end located within the cutting groove. Two symmetrically distributed guide grooves are also formed on the top surface of the working plate, and screws are rotatably connected between the inner surfaces of the two guide grooves. Two second motors for driving the two screws to rotate are mounted at the front end of the working plate. However, this device still has the following problems during use:

[0004] Burrs will appear on the cut end face of stainless steel pipes. After cutting, the steel pipe needs to be transferred to the grinding device, which is inefficient. Furthermore, when the stainless steel pipe is long, the pipe will shift during transportation, affecting the cutting quality.

[0005] Based on this, the present invention designs a stainless steel pipe cutting device with continuous double-end chamfering to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a stainless steel pipe cutting device with continuous double-end chamfering.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A continuous double-end chamfering stainless steel pipe cutting device includes a first base frame, a second base frame, a third base frame, a cutting machine, a ratchet feeding mechanism, a flipping and transferring mechanism, a synchronous moving mechanism, a chamfering machine, and a pneumatic clamp.

The sliding plate is slidably connected to the vertical guide rod. The lower fixed plate is fixedly connected to the moving end of the rodless cylinder. The upper end of the upper fixed plate is equipped with a drive assembly, which is connected to one end of the first connecting rod. Fixed blocks are fixedly installed on both the front and rear sides of the adjacent ends of the upper fixed plate and the sliding plate. The upper end of the second connecting rod is hinged to the fixed block of the upper fixed plate, and the lower end of the second connecting rod is hinged to the other end of the first connecting rod. The lower end of the third connecting rod is hinged to the fixed block of the sliding plate, and the upper end of the third connecting rod is hinged to the lower end of the second connecting rod. Clamping blocks are fixedly installed on the adjacent ends of the upper fixed plate and the sliding plate.

[0015] Furthermore, the drive assembly includes a push block and a cylinder. The cylinder is fixedly mounted on the upper end of the upper fixed plate, and the output end of the cylinder is fixedly connected to the push block. The left and right ends of the push block are hinged to one end of the first connecting rod.

[0016] Furthermore, the two clamping blocks are curved at their closest ends and made of rubber.

[0017] Furthermore, the material transfer mechanism includes a fixed upright plate, a rotary cylinder, and a rotating plate. The fixed upright plate is fixedly installed on the upper right side of the second base frame, and the rotary cylinder is fixedly installed on the left end of the fixed upright plate, with the output end of the rotary cylinder fixedly connected to the rotating plate.

[0020] Furthermore, the cutting machine is a cold saw cutting machine.

[0021] Compared with the prior art, the advantages of this utility model are as follows: The uncut stainless steel pipe enters from the upper left of the first base frame through the conveying device. The steel pipe is fixed by the self-locking clamping assembly. Then, the rodless cylinder drives the self-locking clamping assembly to move to the right. When the right end of the steel pipe moves to the position of the pneumatic clamp on the upper side of the flipping and transferring mechanism, the pneumatic clamp fixes the right side of the steel pipe. The dual-axis cylinder drives the movable clamping block to move backward until the rear end of the movable clamping block is in contact with the front end of the steel pipe. At this time, the middle section of the steel pipe is fixed by the fixed clamping block and the movable clamping block. Then, the self-locking clamping assembly releases the lock on the steel pipe, and the rodless cylinder drives the self-locking clamping assembly to reset.

[0022] Subsequently, the cutting machine cuts the steel pipe at the cutting station. After the cutting is completed, the flipping and transferring mechanism drives the pneumatic clamp with the cut steel pipe fixed on it to rotate from the cutting station to the chamfering station, and the pneumatic clamp at the chamfering station rotates to the cutting station.

[0023] Subsequently, the self-locking clamping assembly works again to fix the steel pipe, and the dual-axis cylinder works to drive the movable clamping block to release the lock on the steel pipe. The rodless cylinder works to drive the self-locking clamping assembly to move to the right again, bringing the right side of the steel pipe to the position of the pneumatic clamp at the cutting station, and fixing it by the pneumatic clamp. By repeating the above operation, continuous unidirectional feeding operation can be achieved for long stainless steel pipes, improving the efficiency of steel pipe cutting.

[0024] When the material transfer mechanism rotates the pneumatic clamp holding the cut steel pipe from the cutting station to the chamfering station, the synchronous movement mechanism moves two chamfering machines simultaneously toward the steel pipe. The chamfering machines then perform the chamfering operation on the steel pipe. After both ends of the steel pipe are chamfered, the pneumatic clamp releases its lock, and the steel pipe falls downwards under its own weight and is removed through a slot in the middle of the second base frame. By switching between the cutting and chamfering stations using the material transfer mechanism, continuous cutting of the steel pipe and double-end chamfering are achieved, improving the practicality of the device.

[0035] In some embodiments, please refer to the accompanying drawings. Figures 1-5 A continuous double-end chamfering stainless steel pipe cutting device includes a first base frame 1, a second base frame 2, a third base frame 3, a cutting machine 4, a ratchet feeding mechanism 5, a flipping and transferring mechanism 6, a synchronous moving mechanism 7, a chamfering machine 8, and a pneumatic clamp 9. The third base frame 3 is fixedly installed on the upper left side of the second base frame 2. The ratchet feeding mechanism 5 for continuous feeding of stainless steel pipes is installed on the upper ends of the first base frame 1 and the upper ends of the third base frame 3. The second base frame 2 is installed on the right side of the first base frame 1.

[0036] The ratchet-type feeding mechanism 5 includes a rodless cylinder 51, a self-locking clamping assembly 52 for fixing the stainless steel pipe, a fixed clamping block 53, a movable clamping block 54, and a dual-axis cylinder 55. The rodless cylinder 51 is fixedly installed in the middle of the upper end of the first base frame 1. The self-locking clamping assembly 52 is installed on the upper end of the moving end of the rodless cylinder 51. The dual-axis cylinder 55 is fixedly installed on the front side of the upper end of the third base frame 3, and the output end of the dual-axis cylinder 55 is fixedly connected to the movable clamping block 54. The fixed clamping block 53 is fixedly installed on the rear side of the upper end of the third base frame 3. The contact surfaces of the fixed clamping block 53 and the movable clamping block 54 with the stainless steel pipe are both arc-shaped and made of rubber.

[0037] A cutting machine 4 is fixedly installed on the upper rear side of the third base frame 3; the installation position of the cutting machine 4 is set as a cutting station;

[0038] The upper end of the second base frame 2 is equipped with a synchronous moving mechanism 7 for controlling the movement of two chamfering machines 8 to chamfer both ends of the steel pipe; the chamfering machines 8 are symmetrically installed on the left and right ends of the synchronous moving mechanism 7; and a through groove for easy material discharge is provided in the middle of the second base frame 2; the upper part of the through groove is set as a chamfering station.

[0039] The upper right side of the second base frame 2 is equipped with a material transfer mechanism 6 for fixing steel pipes and controlling the pneumatic clamp 9 to switch between the cutting station and the chamfering station.

[0040] Pneumatic clamps 9 are symmetrically installed at the upper and lower ends of the flipping and transferring mechanism 6; the movable end of the pneumatic clamps 9 is equipped with a double-claw clamp;

[0041] The cutting machine 4 is a cold saw cutting machine, which avoids the generation of a large number of sparks during cutting, which could cause equipment failure.

[0042] In this utility model, the uncut stainless steel pipe enters from the upper left of the first base frame 1 through the conveying device. The steel pipe is fixed by the self-locking clamping assembly 52. ​​Then, the rodless cylinder 51 works to drive the self-locking clamping assembly 52 to move to the right. When the right end of the steel pipe moves to the position of the pneumatic clamp 9 on the upper side of the flipping and transferring mechanism 6, the pneumatic clamp 9 works to fix the right side of the steel pipe. At the same time, the dual-axis cylinder 55 works to drive the movable clamping block 54 to move backward until the rear end of the movable clamping block 54 is in contact with the front end of the steel pipe. At this time, the middle part of the steel pipe is fixed by the fixed clamping block 53 and the movable clamping block 54. Then, the self-locking clamping assembly 52 releases the lock on the steel pipe, and the rodless cylinder 51 works to drive the self-locking clamping assembly 52 to reset.

[0043] Subsequently, the cutting machine 4 cuts the steel pipe at the cutting station. After the cutting is completed, the flipping and transferring mechanism 6 drives the pneumatic clamp 9, which is fixed with the cut steel pipe, to rotate from the cutting station to the chamfering station, and the pneumatic clamp 9 at the chamfering station rotates to the cutting station.

[0044] Subsequently, the self-locking clamping assembly 52 works again to fix the steel pipe, and the dual-axis cylinder 55 works to drive the movable clamping block 54 to release the lock on the steel pipe. The rodless cylinder 51 works to drive the self-locking clamping assembly 52 to move to the right again, bringing the right side of the steel pipe to the position of the pneumatic clamp 9 at the cutting station, and fixing it by the pneumatic clamp 9. By repeating the above operation, continuous unidirectional feeding operation can be achieved for long stainless steel pipes, improving the efficiency of steel pipe cutting.

[0045] When the material transfer mechanism 6 drives the pneumatic clamp 9, which holds the cut steel pipe, to rotate from the cutting station to the chamfering station, the synchronous movement mechanism 7 drives two chamfering machines 8 to move towards the steel pipe simultaneously. The chamfering machines 8 then perform chamfering on the steel pipe. After chamfering both ends of the steel pipe, the pneumatic clamp 9 releases its lock, and the steel pipe falls downwards under its own weight and is removed through the through-slot in the middle of the second base frame 2. By switching between the cutting and chamfering stations using the material transfer mechanism 6, continuous cutting and double-end chamfering of the steel pipe are achieved, improving the practicality of the device.

[0046] The self-locking clamping assembly 52 includes a fixed plate 521, a vertical guide rod 522, a sliding plate 523, a fixed block 524, a first connecting rod 525, a second connecting rod 526, a third connecting rod 527, a push block 528, a clamping block 529, and a cylinder 5210. The two ends of the vertical guide rod 522 are fixedly installed at the adjacent ends of the two fixed plates 521, and the vertical guide rods 522 are symmetrically distributed on the front and rear sides between the two fixed plates 521. The sliding plate 523 is slidably connected to the vertical guide rod 522. The lower fixed plate 521 is fixedly connected to the moving end of the rodless cylinder 51. The upper end of the upper fixed plate 521 is fixedly installed with the cylinder 5210, and the output end of the cylinder 5210 is fixedly connected to the push block 528. Fixing blocks 524 are fixedly installed on both the front and rear sides of the end of the upper fixing plate 521 and the sliding plate 523 that are close to each other; the left and right ends of the push block 528 are hinged to one end of the first connecting rod 525; the upper end of the second connecting rod 526 is hinged to the fixing block 524 of the upper fixing plate 521, and the lower end of the second connecting rod 526 is hinged to the other end of the first connecting rod 525; the lower end of the third connecting rod 527 is hinged to the fixing block 524 of the sliding plate 523, and the upper end of the third connecting rod 527 is hinged to the lower end of the second connecting rod 526; clamping blocks 529 are fixedly installed on the end of the upper fixing plate 521 and the sliding plate 523 that are close to each other; the end of the two clamping blocks 529 that are close to each other is set to be arc-shaped and made of rubber material, so as to facilitate the fit to the surface of the steel pipe.

[0047] In this utility model, the cylinder 5210 drives the push block 528 to move downward. During the movement, the push block 528 drives the first connecting rod 525 on both sides to rotate. The rotation of the first connecting rod 525 drives the second connecting rod 526 and the third connecting rod 527 to rotate together. The sliding plate 523 drives the clamping block 529 to move downward along the vertical guide rod 522 until the clamping block 529 on the sliding plate 523 and the clamping block 529 on the lower fixing plate 521 are tightly fixed to the steel pipe. At this time, the first connecting rod 525 drives the second connecting rod 526 and the third connecting rod 527 to rotate to the dead point position to achieve self-locking fixation.

[0048] The material transfer mechanism 6 includes a fixed upright plate 61, a rotary cylinder 62, and a rotating plate 63. The fixed upright plate 61 is fixedly installed on the upper right side of the second base frame 2, and the rotary cylinder 62 is fixedly installed on the left end of the fixed upright plate 61. The output end of the rotary cylinder 62 is fixedly connected to the rotating plate 63. Pneumatic clamps 9 are symmetrically fixedly installed on the upper and lower sides of the left end of the rotating plate 63.

[0049] In this utility model, after the steel pipe is cut, the rotary cylinder 62 drives the rotating plate 63 to rotate 180 degrees. At this time, the pneumatic clamp 9 in the cutting position rotates to the chamfering position, and the pneumatic clamp 9 in the chamfering position rotates to the cutting position, so that the cutting and chamfering operations of the steel pipe can be carried out simultaneously without affecting each other.

[0050] The synchronous movement mechanism 7 includes sliding blocks 71, bidirectional lead screws 72, transverse guide rods 73, servo motors 74, and fixed horizontal plates 75. The fixed horizontal plates 75 are symmetrically fixed on the upper left and right sides of the second base frame 2. The left and right ends of the bidirectional lead screw 72 are rotatably mounted on the front side between the two fixed horizontal plates 75. The left and right ends of the transverse guide rod 73 are fixedly mounted on the rear side between the two fixed horizontal plates 75. The front sides of the two sliding blocks 71 are threadedly connected to the bidirectional lead screw 72, and the rear sides of the two sliding blocks 71 are slidably connected to the transverse guide rod 73. The servo motor 74 is fixedly mounted on the left end of the second base frame 2, and the output end of the servo motor 74 is fixedly connected to the left end of the bidirectional lead screw 72. A chamfering machine 8 is fixedly mounted on the upper end of the sliding blocks 71. The two sliding blocks 71 are symmetrically distributed on the left and right sides of the bidirectional lead screw 72 and the transverse guide rod 73.

[0051] In this utility model, when the pneumatic clamp 9 drives the cut steel pipe to rotate to the chamfering station, the servo motor 74 works to drive the bidirectional lead screw 72 to rotate, so that the two sliding blocks 71 move towards the steel pipe along the transverse guide rod 73 at the same time. When the chamfering machine 8 moves to the set position, the servo motor 74 stops working, and the two chamfering machines 8 work at the same time to chamfer both ends of the steel pipe.

[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
