Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically a multi-functional cylindrical cutting and beveling machine. Background Technology

[0002] A cylindrical cutting and beveling machine is a mechanical device used to cut and bevele cylindrical materials. Common cutting methods include planetary, external clamping, and CNC cutting. Among them, planetary and external clamping cutting have limited functions, while CNC cutting has a complex structure and is generally only suitable for processing small-sized cylinders because the manufacturing cost of large-sized machines is extremely high. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-functional cylindrical cutting and beveling machine, which solves the problems mentioned in the background section.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a multifunctional cylindrical cutting and beveling machine, comprising a steel cylinder clamping device and a moving platform. The steel cylinder clamping device contains a cylindrical cylinder to be cut. A cutting bracket is installed above the moving platform. A rotatable shaft is installed at the front end of the cutting bracket. A swingable rocker arm assembly is sleeved in the middle of the shaft. The rocker arm assembly includes a rocker arm with holes. A U-shaped frame is installed at the front end of the rocker arm with holes. A bottom rope nut is threadedly installed below the open end of the U-shaped frame. A top rope nut is threadedly installed above the open end of the U-shaped frame. A wire saw rope is installed between the top rope nut and the bottom rope nut. A light shaft is installed below the rear end of the rocker arm assembly. A compression spring is sleeved on the outer surface of the light shaft. A cam is provided above the cutting bracket near the rear end of the rocker arm assembly. A motor for driving the cam to rotate is installed on one side of the cutting bracket.

[0007] Preferably, the mobile platform is equipped with two mutually perpendicular linear modules. When installed horizontally, it can drive the cutting bracket to move back and forth and left and right in the XY plane. When installed vertically, it can drive the cutting bracket to move up and down and left and right in the YZ plane.

[0008] Preferably, the steel cylinder clamping device can clamp and rotate the cylinder to be cut. Whether the steel cylinder clamping device is installed horizontally or vertically depends on the installation method of the mobile platform, and the wire saw rope is required to cut to the cylinder wall.

[0009] Preferably, the cutting bracket includes a base plate and two vertical plates spaced apart. The rotating shaft passes through the two vertical plates and is connected by two bearings to reduce its rotational resistance. The rocker arm assembly and the cam are both installed between the two vertical plates.

[0010] Preferably, the elastic force generated by the compression of the spring pushes the rear end of the rocker arm assembly upward and makes it contact the lower surface of the cam. When the cam rotates, it can periodically press the rear end of the rocker arm assembly downward, which can make the rocker arm assembly swing back and forth in a small amplitude.

[0011] Preferably, the U-shaped frame is installed at the front end of the perforated swing rod by screws. If the upper and lower sides of the opening of the U-shaped frame are the same length, the wire saw rope is perpendicular to the perforated swing rod. Conversely, if the upper and lower sides of the opening of the U-shaped frame are not the same length, the angle between the wire saw rope and the perforated swing rod is no longer a right angle.

[0012] Preferably, the top rope-mounting nut and the bottom rope-mounting nut have the same structure. Both have a through hole in the middle with an inner diameter slightly larger than the wire saw rope diameter. Both are connected to the U-shaped frame through tapered threads, and grooves are opened around the threads. When tightened, the tapered threads are subjected to force and contract inward to compress the wire saw rope.

[0013] This utility model provides a multi-functional cylindrical cutting and beveling machine, which has the following beneficial effects:

[0014] 1. This multi-functional cylindrical cutting and beveling machine, through the coordinated design of the swing arm assembly and the wire saw rope, enables it to cut a wide range of sizes. Since the U-shaped frame at the front end of the swing arm assembly that mounts the wire saw rope can be disassembled and replaced, the length of the wire saw rope can be changed. When cutting small-sized cylinders, a wire saw rope longer than its diameter is used for a single cut, while when cutting large-sized cylinders, a wire saw rope longer than its wall thickness is used for a single-sided cut, thus achieving the ability to cut both small and large-sized cylinders.

[0015] 2. This multi-functional cylindrical cutting and beveling machine, through the coordinated arrangement of the steel cylinder clamping device, the moving platform, the swing arm assembly, and the wire saw rope, enables the machine to have multiple cutting functions. The relative position and angle between the wire saw rope and the cylinder can be changed by the steel cylinder clamping device and the moving platform. By changing the U-shaped frame at the front end of the swing arm assembly, the tilt angle of the wire saw rope can be changed to change the cutting angle of the cylinder, thus making the cutting angle variable and achieving a variety of cutting effects.

[0016] 3. This multi-functional cylindrical cutting and beveling machine, through the coordinated arrangement of the steel cylinder clamping device, the moving platform, and the swing arm assembly, enables it to cut large-diameter cylinders at a low cost. Since the U-shaped frame at the front end of the swing arm assembly can drive the wire saw rope to cut the cylinder on one side, when the cylinder is installed vertically, only a larger clamp needs to be replaced to use a smaller steel cylinder clamping device and a smaller moving platform to cut large-diameter cylinders, thereby reducing the cost of cutting large-diameter cylinders.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1 to 6This utility model provides a technical solution: a multi-functional cylindrical cutting and beveling machine, including a steel cylinder clamping device 1 and a moving platform 2. The steel cylinder clamping device 1 contains a cylindrical cylinder 3 to be cut. A cutting bracket 4 is installed above the moving platform 2. The moving platform 2 has two mutually perpendicular linear modules. When horizontally installed, the cutting bracket 4 can be driven to move forward, backward, left, and right in the XY plane; when vertically installed, the cutting bracket 4 can be driven to move up, down, left, and right in the YZ plane. A rotatable shaft 5 is installed at the front end of the cutting bracket 4. A swingable rocker arm assembly 6 is sleeved in the middle of the shaft 5. The rocker arm assembly 6 includes a perforated rocker arm 601. The perforated rocker arm 601 has a front... A U-shaped frame 602 is installed at one end. A bottom rope nut 603 is threadedly installed below the open end of the U-shaped frame 602, and a top rope nut 604 is threadedly installed above the open end of the U-shaped frame 602. A wire saw rope 7 is installed between the top rope nut 604 and the bottom rope nut 603. The steel cylinder clamping device 1 can clamp and rotate the cylinder 3 to be cut. Whether the steel cylinder clamping device 1 is installed horizontally or vertically depends on the installation method of the moving platform 2. It is required that the wire saw rope 7 can cut to the cylinder wall, and the cutting effect will vary depending on the angle between the cylinder 3 to be cut and the wire saw rope 7. The U-shaped frame 602 is installed on the perforated swing rod 601 with screws. At the front end, if the upper and lower sides of the opening of the U-shaped frame 602 are of the same length, the wire saw rope 7 is perpendicular to the perforated swing rod 601. Conversely, if the upper and lower sides of the opening of the U-shaped frame 602 are not of the same length, the angle between the wire saw rope 7 and the perforated swing rod 601 is no longer a right angle. Changing the angle of the wire saw rope 7 can change the cutting effect. The top rope nut 604 and the bottom rope nut 603 have the same structure. Both have a through hole with an inner diameter slightly larger than the wire diameter of the wire saw rope 7. Both are connected to the U-shaped frame 602 through tapered threads, and grooves are opened around the threads. When tightened, the tapered threads are subjected to force and contract inward to compress the wire saw rope 7. A swing rod assembly 6 is installed at the lower rear end. The optical axis 8 has a compression spring 9 sleeved on its outer surface. A cam 10 is provided above the rear end of the cutting bracket 4 near the rear end of the rocker arm assembly 6. A motor 11 that drives the cam 10 to rotate is installed on one side of the cutting bracket 4. The cutting bracket 4 includes a base plate and two vertical plates with a certain distance between them. The rotating shaft 5 passes through the two vertical plates and is connected by two bearings to reduce the rotational resistance. The rocker arm assembly 6 and the cam 10 are both installed between the two vertical plates. The elastic force generated by the compression of the compression spring 9 pushes the rear end of the rocker arm assembly 6 upward and makes it contact the lower surface of the cam 10. When the cam 10 rotates, it can periodically press the rear end of the rocker arm assembly 6 downward, which can make the rocker arm assembly 6 swing back and forth in a small amplitude.

[0026] Example 1:

[0027] The diameter and wall thickness of the cylinder 3 to be cut are relatively small. The moving platform 2 is installed horizontally, and the steel cylinder clamping device 1 is also horizontally clamped to the cylinder 3 to be cut. A wire saw rope 7 with a length greater than the diameter of the cylinder 3 to be cut is installed at the front end of the swing arm assembly 6. The steel cylinder clamping device 1 further clamps the cylinder 3 to be cut and fixes it in place. The moving platform 2 drives the wire saw rope 7 to approach the cylinder 3 to be cut, and then the motor 11 works. The motor 11 drives the swing arm assembly 6 to swing up and down, and at the same time the wire saw rope 7 also moves up and down. The moving platform 2 drives the up and down moving wire saw rope 7 to cut into the cylinder 3 to be cut. If cutting a flat opening, the wire saw rope 7 only moves back and forth. If cutting a bevel or arc opening, the wire saw rope 7 moves both back and forth and left and right.

[0028] Example 2:

[0029] When the diameter and wall thickness of the cylinder 3 to be cut are large, the moving platform 2 can be installed horizontally or vertically. Then, the steel cylinder clamping device 1, in conjunction with the moving platform 2, horizontally or vertically clamps and rotates the cylinder 3 to be cut. A wire saw rope 7 with a length greater than the wall thickness of the cylinder 3 is installed at the front end of the swing arm assembly 6. The moving platform 2 further drives the wire saw rope 7 closer to the end face of the cylinder 3 to be cut, requiring the middle of the wire saw rope 7 to be located in front of the cylinder wall on one side of the cylinder 3 to be cut, and the wire saw rope 7 to be as close as possible to the end face of the cylinder to be cut. In the radial direction of cylinder 3, the motor 11 further drives the rocker arm assembly 6 to swing up and down, while the wire saw rope 7 also vibrates back and forth along the radial direction of the cylinder. The moving platform 2 further drives the wire saw rope 7 to cut into the side wall of the cylinder 3 to be cut. The steel cylinder clamping device 1 further starts to rotate the cylinder 3 to be cut. At this time, if it is a flat cut, the position of the wire saw rope 7 does not change, only the cylinder 3 to be cut rotates. If it is a bevel or arc cut, the wire saw rope 7 moves to change the cutting depth and rotates the cylinder 3 to be cut.

[0030] Example 3:

[0031] When the diameter and wall thickness of the cylinder 3 to be cut are both very large, the moving platform 2 is installed vertically, and then the steel cylinder clamping device 1 vertically clamps the cylinder 3 to be cut and rotates it. A wire saw rope 7 with a length greater than the wall thickness of the cylinder 3 is installed at the front end of the swing arm assembly 6. The moving platform 2 further drives the wire saw rope 7 to approach the upper end face of the cylinder 3 to be cut, requiring the middle of the wire saw rope 7 to be located in front of the cylinder wall on one side of the cylinder 3 to be cut, and the wire saw rope 7 to be located as far as possible in the radial direction of the cylinder 3 to be cut. The motor 11 further drives the swing arm assembly 6 to swing up and down, and at the same time the wire saw rope 7 also vibrates back and forth along the radial direction of the cylinder. The moving platform 2 further drives the wire saw rope 7 to move downward and cut into the side wall of the cylinder 3 to be cut. The steel cylinder clamping device 1 further starts to rotate the cylinder 3 to be cut. At this time, if it is a flat cut, the position of the wire saw rope 7 does not change, only the cylinder 3 to be cut rotates. If it is a bevel or arc cut, the wire saw rope 7 moves to change the cutting depth and rotates the cylinder 3 to be cut.

[0032] Example 4:

[0033] When the cylinder 3 to be cut needs to be chamfered, the moving platform 2 is installed horizontally, and then the steel cylinder clamping device 1 is tilted to clamp the cylinder 3 to be cut and rotated. Alternatively, the moving platform 2 is installed horizontally, but the U-shaped frame 602 is replaced to make the wire saw rope 7 tilt at an angle, and then the steel cylinder clamping device 1 is vertically clamped to clamp the cylinder 3 to be cut and rotated. The moving platform 2 further drives the wire saw rope 7 to approach the end face of the cylinder 3 to be cut. The angle of the wire saw rope 7 relative to the cylinder 3 to be cut and the size of the cutting angle are adjusted according to the cutting requirements. The motor 11 further drives the swing arm assembly 6 to swing up and down, while the wire saw rope 7 vibrates back and forth. The moving platform 2 further drives the wire saw rope 7 to cut into the cylinder 3 to be cut. After that, the moving platform 2 drives the wire saw rope 7 or the steel cylinder clamping device 1 to rotate the cylinder 3 to be cut, which can be controlled according to the requirements. In this way, various required bevels can be cut.

[0034] In summary, this multi-functional cylinder cutting and beveling machine features a U-shaped frame 602 at the front end of the swing arm assembly 6 that allows for the removal and replacement of the wire saw rope 7. Therefore, the length of the wire saw rope 7 can be varied. When cutting small cylinders, a wire saw rope 7 longer than its diameter is used for a single cut; when cutting large cylinders, a wire saw rope 7 longer than its wall thickness is used for a single-sided cut. This allows for the cutting of both small and large cylinders. The relative position and angle between the wire saw rope 7 and the cylinder can be changed via the cylinder clamping device 1 and the moving platform 2. The angle of the wire saw rope 7 can be changed by replacing the U-shaped frame 602 at the front end of the swing arm assembly 6, thereby changing the angle of the cut cylinder and making the cut angle more varied, thus achieving a variety of cutting effects. Since the U-shaped frame 602 at the front end of the swing arm assembly 6 can drive the wire saw rope 7 to cut the cylinder on one side, when the cylinder is installed vertically, only a larger clamp needs to be replaced to use a small-sized steel cylinder clamping device 1 and a small-sized moving platform 2 to cut large-diameter cylinders, thereby reducing the cost of cutting large-diameter cylinders.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
