Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing and relates to a cutting device, in particular to a multi-angle cutting device for pipe processing. Background Art

[0002] During mechanical processing, such as processing of metal and non-metal parts, a cutting device is usually used to complete the cutting of the metal and non-metal parts.

[0003] For example, steel pipes require a cutting device to cut steel during processing; for example, aluminum pipes require different cross-sections of aluminum profiles in different usage scenarios, so a cutting machine is required to cut the cross-section of the aluminum profile into different angles. The existing method is that people manually mark the cutting lines at the positions where the aluminum profiles need to be cut to ensure the cutting angle, and then use a cutting machine to cut the aluminum profiles with marked cutting lines; various non-metallic solid materials, such as plastic pipes, PVC pipes, PVB pipes and other industrial and civilian materials, also need to be cut.

[0004] Existing pipe cutting equipment has low working efficiency and does not have the function of collecting waste chips during the pipe processing. If the waste chips generated by pipe cutting are not cleaned in time, the splashed pipe waste chips will easily fall to the ground, causing environmental pollution and reducing the working efficiency of the pipe cutting equipment.

[0005] Another problem is that the cutting angle is difficult to adjust. Most of the time, people need to manually adjust the cutting angle of the cutting machine. The traditional cutting device can only cut in a fixed straight line and cannot adjust the cutting angle. It cannot meet the needs of multi-angle cutting of pipes, which causes great inconvenience to steel processing.

[0006] Therefore, we propose a multi-angle cutting device for pipe processing, which can form an automated assembly line pipe cutting operation, stably convey and clamp pipes, perform fixed-length cutting, straight cutting, bevel cutting and special-shaped cutting, and the cut pipes can be automatically picked up and unloaded. It can effectively collect debris, filter the smoke generated by cutting, and form air circulation. Summary of the Invention

The technical problem to be solved by the invention is: how to realize automated assembly line multi-angle cutting operation for pipes.

[0008] The purpose of the present invention can be achieved through the following technical solutions:

[0009] A multi-angle cutting device for pipe processing comprises a quantitative cutting mechanism, a conveying chain mechanism and a fixed bracket which are arranged in sequence; an adjustable cutting mechanism is arranged above the quantitative cutting mechanism; a wire cutting mechanism is arranged at the upper end of the fixed bracket; two clamping mechanisms are respectively arranged on both sides of the conveying chain mechanism, and every two clamping mechanisms at opposite positions form a group; a wire cutting mechanism is arranged at the upper end of the fixed bracket; the two groups of clamping mechanisms are respectively located directly below the adjustable cutting mechanism and the wire cutting mechanism; two symmetrical dust outlet pipes are provided on the quantitative cutting mechanism; a debris collecting box is provided inside the conveying chain mechanism; the ends of the two dust outlet pipes are connected to the debris collecting box; a fan is provided on the front side of the fixed bracket; the air inlet end of the fan is connected to the debris collecting box; the air outlet end of the fan is connected to the adjustable cutting mechanism and the wire cutting mechanism.

[0010] The working principle of the present invention is as follows: the pipe is placed on the quantitative cutting mechanism and cut to a fixed length. The cut pipes are transported to the conveyor chain mechanism. If the pipe only needs straight cutting and bevel cutting, the conveyor chain mechanism transports the cut pipes to the top of the two clamping mechanisms of the first group. The two clamping mechanisms there clamp the cut pipes and fix them. The adjustable cutting mechanism performs straight cutting and bevel cutting at a certain angle on the pipes. If the pipe only needs special-shaped cutting, the conveyor chain mechanism transports the cut pipes to the top of the two clamping mechanisms of the second group. The two clamping mechanisms there clamp the cut pipes and fix them. The parts are clamped and fixed, and the wire cutting mechanism performs special-shaped cutting on the pipe fittings. Debris will be generated during fixed-length cutting, straight cutting, bevel cutting at a certain angle, and special-shaped cutting. The debris from fixed-length cutting is introduced into the debris collecting box through the dust outlet pipe, and the debris from straight cutting, bevel cutting at a certain angle, and special-shaped cutting falls into the debris collecting box. The air inlet end of the fan is connected with the debris collecting box to form a negative pressure to absorb the smoke and very small debris generated during the cutting process. The air outlet end of the fan is connected with the adjustable cutting mechanism and the wire cutting mechanism, and air is blown to the adjustable cutting mechanism and the wire cutting mechanism to form an air circulation.

[0012] The above structure is adopted to place the pipe on the guide plate, and the pipe slides along the guide plate to the conveying guide chain plate. The output shaft of the conveying motor drives one of the rotating shafts of the conveying guide chain plate to rotate through the conveying sprocket pair, thereby conveying the pipe on the conveying guide chain plate to the saw blade. Several elastic baffle plates cooperate with the conveying guide chain plate to prevent the pipe from shaking. The output shaft of the saw blade motor drives the saw blade rotating shaft to rotate through the saw blade sprocket pair, thereby driving the saw blade to rotate at high speed. The pipe is cut to a fixed length, and the waste at both ends falls on the two conveyor crawlers. The output shaft of the conveying motor drives one of the rotating shafts of the two conveyor crawlers to rotate through the crawler sprocket pair, thereby driving the conveyor crawler to convey the waste, and transport it to the discharge chute plate, and it slides along the discharge chute plate for discharge.

[0013] The dust outlet pipe is fixed on the cutting frame, and an avoidance hole is opened on the dust outlet pipe. The saw blade is located at the avoidance hole of the dust outlet pipe at the corresponding position.

Then, the first electric transverse seat and the first electric vertical seat cooperate to bevel the pipe fitting along the bevel angle. The output shaft of the cutting motor drives the saw blade to rotate at high speed through the transmission pulley pair for cutting. The dust cover is used to block cutting debris.

[0019] The wire cutting mechanism includes a second electric vertical moving seat, which is fixed to the upper end of the fixed bracket 1. A second electric horizontal moving seat is fixed on the moving seat of the second electric vertical moving seat, and a wire cutting component is provided on the moving seat of the second electric horizontal moving seat.

[0020] With the above structure, the second electric vertical moving seat and the second electric horizontal moving seat cooperate to drive the wire cutting assembly to move, thereby meeting the special-shaped cutting requirements of the wire cutting assembly.

[0021] The wire cutting assembly includes a wire cutting box, which is fixed on the moving seat of the second electric transverse seat. The wire cutting box is C-shaped, and a number of cutting wire guide wheels are provided for rotation inside the wire cutting box. The inside of the wire cutting box is hinged with a tensioning push rod and a tensioning connecting rod.

[0026] With the above structure, the telescopic end of the lifting push rod drives the vertical axis of the push rod to rise, thereby driving the electric clamp at the upper end to rise. The electric clamp contacts the two ends of the pipe fitting, and the electric clamp clamps the two ends of the pipe fitting and fixes them. Then, the adjustable cutting mechanism and the wire cutting mechanism are used to cut.

The output shaft of the rotation motor 55 drives the input shaft of the cam divider 54 to rotate, and the output shaft of the cam divider 54 drives the turntable 56 to rotate, thereby moving the cut pipe fitting out of the conveyor chain mechanism 7, and then the electric clamp 58 opens, and the pipe fitting is unloaded, and the clamping mechanism 6 is reset.

[0062] Working principle of the present invention:

[0063] The pipe is placed on the guide plate 8, the pipe slides along the guide plate 8 to the conveying guide chain plate 19, and the output shaft of the conveying motor 21 drives one of the rotating shafts of the conveying guide chain plate 19 to rotate through the conveying sprocket pair 20, thereby conveying the pipe on the conveying guide chain plate 19 to the saw blade 15. Several elastic baffle plates 14 cooperate with the conveying guide chain plate 19 to prevent the pipe from shaking. The output shaft of the saw blade motor 18 drives the saw blade rotating shaft 16 to rotate through the saw blade sprocket pair 17, thereby driving the saw blade 15 to rotate at high speed, and the pipe is cut to a fixed length. The waste at both ends falls on the two conveyor crawlers 12, and the output shaft of the conveying motor 21 drives one of the rotating shafts of the two conveyor crawlers 12 to rotate through the crawler sprocket pair 22, thereby driving the conveyor crawler 12 to convey the waste and convey it to the discharge chute plate 11, and slides along the discharge chute plate 11 for discharge; the cut debris goes along the dust discharge pipe 13, through the debris inlet 25, and enters the debris collection box 29;

[0064] The cut fixed-length pipes fall onto the conveyor chain plate 27. The output shaft of the conveyor motor 24 drives the rotating shaft of the conveyor chain plate 27 to rotate through the conveyor sprocket pair 26, so that the conveyor chain plate 27 moves to convey the cut fixed-length pipes.

[0065] If the pipe only needs straight cutting and bevel cutting, the conveyor chain mechanism 7 conveys the cut pipe to the top of the two clamping mechanisms 6 of the first group, and the telescopic end of the lifting push rod 62 drives the push rod vertical shaft 60 to rise, thereby driving the electric clamping claw 58 at the upper end to rise, and the electric clamping claw 58 contacts the two ends of the pipe, and the electric clamping claw 58 clamps the two ends of the pipe; the first electric transverse movement seat 31 drives the saw blade 41 to move left and right for adjustment, and the first electric vertical movement seat 32 drives the saw blade 41 to move up and down for cutting and retracting, and the telescopic end of the electric push rod 34 drives the rotation of the rotating shaft through the connecting rod 35, thereby driving the cutting motor 37 and the saw blade fixing seat 39 to rotate a certain angle to form a bevel angle, and then the first electric transverse movement seat 31 and the first electric vertical movement seat 32 cooperate to bevel the pipe along the bevel angle, and the output shaft of the cutting motor 37 drives the saw blade 41 to rotate at high speed through the transmission pulley pair 38 for cutting. The dust cover 40 is used to block cutting debris. Straight cutting does not require angle adjustment;

[0066] If the pipe only needs to be cut into special shapes, the conveyor chain mechanism 7 conveys the cut pipe to the top of the two clamping mechanisms 6 of the second group. The telescopic end of the lifting push rod 62 drives the push rod vertical shaft 60 to rise, thereby driving the electric clamping claw 58 at the upper end to rise. The electric clamping claw 58 contacts the two ends of the pipe and clamps the two ends of the pipe.

[0067] The second electric vertical movement seat 42 and the second electric horizontal movement seat 43 cooperate to drive the wire cutting assembly 44 to move. The output shaft of the wire cutting motor 48 drives the rotation shaft of one of the cutting wire guide wheels 49 to rotate, thereby cooperating with the cutting wire 45 through the cutting wire guide wheels 49, the tensioning guide wheel 51 and the two guide wheels 46 to drive the cutting wire 45 to move back and forth at high speed to perform special-shaped cutting on the pipe fitting;

[0068] After the cutting is completed, the telescopic end of the lifting push rod 62 drives the push rod vertical shaft 60 to continue to rise, driving the pipe to rise and leave the conveyor chain mechanism 7. The output shaft of the rotary motor 55 drives the input shaft of the cam divider 54 to rotate. The output shaft of the cam divider 54 drives the turntable 56 to rotate, thereby moving the cut pipe out of the conveyor chain mechanism 7. Then the electric clamp 58 opens, and the pipe is unloaded. The clamping mechanism 6 is reset again.

[0069] When cutting to a fixed length, cutting straight, cutting at a certain angle, or cutting in a special shape, debris will be generated. The debris from cutting to a fixed length is introduced into the debris collecting box 29 through the dust outlet pipe 13. The debris from cutting straight, cutting at a certain angle, or cutting in a special shape falls into the debris collecting box 29. The air inlet end of the fan 5 is connected to the debris collecting box 29, forming a negative pressure to absorb the smoke and very small debris generated during the cutting process. A filter box is fixed inside the lower end of the debris collecting box 29 to filter the smoke generated during the pipe cutting process to obtain clean air, which is then blown into the dust cover 40 and the exhaust hood through the pipe and blown at the cutting position to form an air circulation.

[0070] In summary, the quantitative cutting mechanism 1 is used to stably cut the pipe to a fixed length, and cooperates with the dust outlet pipe 13 to achieve that the cut debris falls inside the dust outlet pipe 13 and enters the debris collection box 29 along the dust outlet pipe 13, which is environmentally friendly and safe.

[0071] The conveying chain mechanism 7 cooperates with the two sets of clamping mechanisms 6 to carry out stable conveying and stable clamping. At the same time, the clamping mechanism 6 takes and unloads the cut pipes.

[0072] By cooperating with the two sets of clamping mechanisms 6 and the adjustable cutting mechanism 2, straight cutting and bevel cutting of the pipe fittings can be achieved; by cooperating with the two sets of clamping mechanisms 6 and the wire cutting mechanism 3, special-shaped cutting of the pipe fittings can be achieved;

[0073] Debris is collected by cooperating with the dust outlet pipe 13 and the debris collecting box 29. The debris collecting box 29 cooperates with the fan 5. A filter box is fixed inside the lower end of the debris collecting box 29 to filter the smoke generated during the pipe cutting process to obtain clean wind, which is then formed through the fan 5 in cooperation with the dust cover 40 and the exhaust hood to form an air circulation.

Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
