Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel pipe beveling machines, specifically to a stainless steel pipe beveling machine with a quick tool change function. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material, widely used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as in mechanical structural components. Additionally, it is lighter in weight while maintaining the same bending and torsional strength, making it widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used in furniture and kitchenware.

[0003] A pipe bevel is a slope formed by grinding and processing the joint when welding pipes together. Bevels can be 45 degrees or 30 degrees. Before welding steel pipes, beveling is usually required, which means processing a bevel on the end face.

[0004] Chinese patent CN201644888U discloses a steel pipe beveling machine. The solution describes that by organically combining several limited components, such as a main shaft sleeve connected to the machine frame, a main shaft rotatably connected inside the main shaft sleeve, a tool holder and a spline shaft connected to the main shaft, and a clamping device and a power device connected to the machine frame, the purpose can be achieved. Therefore, this utility model has the advantages of simple structure and low manufacturing cost, and can easily realize the beveling processing of the ends of steel pipes.

[0005] However, in the process of using the above solution, the steel pipe is placed in the clamping device manually for fastening, thereby beveling the end of the steel pipe. However, since the steel pipe is manually pushed to feed, the accuracy of the steel pipe's feeding position cannot be guaranteed, which in turn affects the processing accuracy and effect of the steel pipe beveling.

[0015] Preferably, the top end of the transmission column is fixedly installed to the rear end of the upright frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model provides a stainless steel pipe beveling machine with a quick tool change function. Through the feeding mechanism, the stainless steel pipe is placed inside two sets of fixed seats. Then, by rotating the rotating shaft, the main sprocket rotates. The main sprocket, through the meshing effect of the chain, drives the auxiliary sprockets on both sides to rotate, which in turn drives the lead screws on both sides to rotate synchronously. These lead screws push the threaded movable seats downwards, allowing the movable seats to clamp and fix the stainless steel pipe in conjunction with the fixed seats, preventing loosening during grinding. The rotating lead screw drives the two sets of threaded movable seats to move uniformly towards the vertical frame, allowing the movable seats to drive the fixed and movable seats to move synchronously, thus pushing the steel pipe for feeding. This eliminates the need for manual feeding, allowing control of the steel pipe's feed depth, improving the stability of the steel pipe during processing, and enhancing processing accuracy and effect.

[0018] 2. This utility model provides a stainless steel pipe beveling machine with a quick tool change function. Through the cutting assembly, the rotating bidirectional screw can drive the threaded seats on both sides to move closer or further apart. Then, the fixed plate can drive the grinding tools on both sides to move, so that the grinding tools can make close contact with one end of the steel pipe. At this time, the rotating transmission column can drive the vertical frame to rotate, which can drive the rotating grinding tool to grind the end of the steel pipe. By loosening the nut in the fastener, the fastening bolt can be easily removed from the through hole, so that the grinding tool can be quickly removed from the fixed block. This allows for quick replacement of grinding tools with different angles, enabling grinding of the steel pipe at different angles.

[0019] 3. This utility model provides a stainless steel pipe beveling machine with a quick tool changing function. When the steel pipe is beveling by the grinding tool, a large amount of debris is generated through the dust removal mechanism. At this time, the dust suction fan can be started so that the dust suction pipe can absorb the generated debris and suck it into the dust collection box, so as to avoid the debris affecting the beveling process. At the same time, the debris can also be collected for convenient centralized treatment. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] like Figures 1-5 As shown, this utility model provides a stainless steel pipe beveling machine with a quick tool change function, including a machine base 1. A horizontal plate 2 is symmetrically fixed on the upper right side of the machine base 1. A feeding mechanism 3 is provided inside the horizontal plate 2. A stainless steel pipe 4 is movably installed inside the upper end of the feeding mechanism 3. A vertical frame 5 is provided on the upper left side of the machine base 1. A cutting assembly 6 is provided inside the vertical frame 5. A dust removal mechanism 7 is provided below the cutting assembly 6. A mounting base 8 is fixed on the upper right side of the machine base 1. A vertical frame 9 is fixed on the upper end of the mounting base 8. A motor 10 is fixed on the inner side of the top of the vertical frame 9. A transmission column 11 is installed at the output end of the motor 10.

[0028] The top of the transmission column 11 is fixedly installed to the rear end of the upright frame 5.

[0029] In this scheme, the motor 10 drives the vertical frame 5 to rotate through the transmission column 11, so that the vertical frame 5 drives the grinding cutter 65 to rotate synchronously, so that one end of the stainless steel pipe 4 can be ground to complete the beveling process.

[0030] like Figure 3 As shown, the feeding mechanism 3 includes a lead screw 21. Both ends of the lead screw 21 are rotatably mounted to the inner center of the cross plate 2. Limiting rods 22 are symmetrically fixed on both sides of the lead screw 21. A movable seat 23 is slidably mounted on the outside of the lead screw 21 and the limiting rods 22. A fixed seat 24 is fixedly mounted on the upper end of the movable seat 23. Guide rods 25 are symmetrically fixed on both sides of the upper end of the fixed seat 24. A top plate 26 is fixedly mounted on the top of the guide rods 25. The upper inner side is symmetrically and rotatably mounted with lead screws 27. The top of each set of lead screws 27 is fixedly equipped with a secondary sprocket 28. The upper middle part of the top plate 26 is rotatably mounted with a shaft 29. The outside of the shaft 29 is fixedly sleeved with a main sprocket 210. The outside of the main sprocket 210 and the secondary sprocket 28 are sleeved with meshing chains 211. The guide rod 25 and the outside of the lead screws 27 are slidably sleeved with a movable seat 212. One end of the horizontal plate 2 is fixedly equipped with a motor 213.

[0031] The top end of lead screw 21 is driven and installed with the output end of motor 213. The outside of lead screw 21 is threaded with the middle of the moving seat 23. The top end of lead screw 27 is rotated and installed through both sides of the top plate 26.

[0032] A knob is fixedly installed on the top of the rotating shaft 29. The external of the lead screw 27 is threaded onto the internal sides of the movable seat 212. Arc-shaped holes are opened on the opposite surfaces of the fixed seat 24 and the movable seat 212.

[0033] In this solution, by facilitating the control of the feed depth of the steel pipe, the stability of the steel pipe during the processing is improved, the processing accuracy and processing effect are enhanced, and the problem of unstable feed depth caused by uneven force or operation error during manual feeding is avoided, thereby significantly improving the stability of the steel pipe processing process.

[0034] like Figure 4 As shown, the cutting assembly 6 includes a bidirectional screw 61, with both ends of the bidirectional screw 61 rotatably mounted inside the frame 5. Threaded seats 62 are threaded onto both sides of the bidirectional screw 61. A fixing block 63 is fixedly mounted at the front end of the threaded seat 62. A groove 64 is formed on the top of the fixing block 63. A grinding tool 65 is movably mounted inside the groove 64. Through holes 66 are formed on the surfaces of both the groove 64 and the grinding tool 65. Fasteners 67 are movably mounted inside the through holes 66. Limiting grooves 68 are symmetrically formed on both sides of the frame 5. Limiting blocks 69 are symmetrically fixed at both ends of the threaded seat 62. A motor 610 is fixedly mounted on the top of the frame 5.

[0035] The top end of the bidirectional screw 61 is driven and installed at the output end of the motor 610. The fastener 67 is a fastening bolt and nut, and the fastener 67 is inserted through the through hole 66. The limiting block 69 matches the limiting groove 68 and is slidably connected.

[0036] In this design, when the threaded seat 62 moves, it will cause the limiting block 69 to slide synchronously in the limiting groove 68 to limit its movement. By loosening and removing the nut in the fastener 67, the fastening bolt can be pulled out from the through hole 66 so that the grinding cutter 65 can be taken out from the groove 64 on the fixing block 63. Then, different sizes of grinding cutters 65 can be replaced, and they can be fastened again with the fastener 67. This allows the steel pipe to be ground at different angles, and the grinding cutter 65 can be replaced quickly.

[0037] like Figure 5 As shown, the dust removal mechanism 7 includes a connecting plate 71. The lower end of the connecting plate 71 is fixedly connected to the upper left side of the machine base 1. A dust suction hood 72 is fixedly provided on the upper end of the connecting plate 71. Several hollow grooves 73 are opened on the upper surface of the dust suction hood 72. A dust suction pipe 74 is fixedly provided on the lower end of the dust suction hood 72. A dust collection box 75 is fixedly provided on the upper left rear side of the machine base 1. A filter plate 76 is fixedly provided on the lower end of the interior of the dust collection box 75. A connected dust suction fan 77 is fixedly provided on the lower side of one side of the dust collection box 75.

[0038] The dust hood 72 is located below the grinding blade 65. The dust suction pipe 74 is fixedly connected to the upper rear end of the dust collection box 75. The dust hood 72, the dust suction pipe 74 and the interior of the dust collection box 75 are interconnected. A door is hinged to the front of the dust collection box 75.

[0039] In this design, the hollowed-out groove 73 facilitates the entry of processing debris into the dust collection hood 72. The dust removal structure can collect the debris when it is generated, preventing it from accumulating in the processing area. This ensures the normal operation of the grinding tool 65 and maintains the stability and accuracy of the processing.

[0040] The working principle of this stainless steel pipe beveling machine with quick tool change function will be explained in detail below.

[0041] like Figures 1-5As shown, when using this stainless steel pipe beveling machine with quick tool change function, the stainless steel pipe 4 to be processed can first be placed in the two sets of fixed seats 24. Then, the rotating shaft 29 can be rotated by the knob. The rotating shaft 29 drives the main sprocket 210 to rotate synchronously. The main sprocket 210 transmits the rotational motion synchronously to the auxiliary sprockets 28 on both sides through the meshing action of the chain 211, thereby causing the lead screws 27 on both sides to rotate synchronously. As the lead screws 27 rotate, they can push the threaded movable seat 212 to move downward in a straight line along the guide rod 25. The fixed seat 24 and the movable seat 212 can evenly clamp the steel pipe, making it less prone to movement and displacement during processing. With one end of the clamped steel pipe positioned inside the two sets of grinding cutters 65, motor 610 can be started. Motor 610 drives the bidirectional screw 61 to rotate, causing the threaded seats 62 on both sides to move closer together. The threaded seats 62, through the fixed block 63, drive the grinding cutters 65 to move synchronously, thus ensuring close contact between the two sets of grinding cutters and one end of the steel pipe. At this point, motor 10 can also be started. 10. The transmission column 11 drives the vertical frame 5 to rotate, which in turn drives two sets of grinding cutters 65 to rotate, allowing the grinding cutters 65 to grind the ends of the steel pipe. By starting the second motor 213, the second motor 213 drives the first lead screw 21 to rotate. The first lead screw 21 drives the threaded movable seat 23 to move to the left under the limiting guide of the limiting rod 22. The movable seat 23 drives the fixed seat 24 and the movable seat 212 to move synchronously, so as to push the steel pipe for uniform feeding. After the steel pipe moves to a suitable depth, the rotating grinding cutters 65 can... The steel pipe is beveled by grinding with a slope to complete the beveling of the stainless steel pipe 4. When the grinding cutter 65 beveles the steel pipe, a large amount of metal shavings will be generated. At this time, the dust extraction fan 77 can be started, and the dust extraction hood 72 and dust extraction pipe 74 under the vertical frame 5 can absorb the processed shavings and suck them into the dust collection box 75. The filter plate 76 can trap the shavings in the dust collection box 75, thereby completing the centralized collection of shavings. This can improve the cleanliness of the machine table 1, and the shavings will not affect the beveling of the steel pipe.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
