Description

Technical Field

[0001] The present invention relates to the technical field of riser cutting, and particularly to a riser cutting device and method for the blank of the compressor dynamic and static disks. Background Art

[0002] During the casting process of the blank of the compressor dynamic and static disks, risers are required. A riser refers to a supplementary part attached above or on the side of the casting to avoid defects in the casting. After the casting of the dynamic and static disk blanks is completed, the risers need to be cut off.

[0003] When the existing riser cutting devices perform riser cutting, generally, a cutting tool is directly used to cut off the connection between the riser and the blank. However, for a cylindrical riser, the diameter of the lower connection part is small, and the cutting tool can directly complete the cutting operation under the push of a cylinder. For some elliptical risers, the longest diameter is large, and the transverse pushing distance of the cutting tool is long, which easily causes the cutting tool to break during the transverse pushing process, affecting the progress of riser cutting and posing a certain safety hazard.

Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] A riser cutting device for the rough blank of the dynamic and static disks of a compressor disclosed by the present invention is mainly applied to the scenario where when the existing riser cutting device cuts the riser, generally a cutting tool directly cuts the connection between the riser and the blank. However, for a cylindrical riser, the diameter of the lower connection is small, and the cutting tool can complete the cutting operation directly under the push of the cylinder. For some elliptical risers, the longest diameter is large, and the transverse pushing distance of the cutting tool is long, which is likely to cause the cutting tool to break during the transverse pushing process, affecting the progress of riser cutting and posing a certain safety hazard.

[0033] Refer to Figures 1 - 10, A riser cutting device for the moving and static disk blanks of a compressor, comprising an annular mounting rail 1 and a constant-distance cutting mechanism 5. The constant-distance cutting mechanism 5 includes a rotating disk 501, a guardrail frame 504, and two adjusting tool holders 506. A docking mechanism 9 is provided on both of the two adjusting tool holders 506. The docking mechanism 9 includes a docking frame 901. A cutting blade 7 is fixedly connected to the bottom of the docking frame 901. The adjusting tool holder 506 is provided with a through-fitting hole at the position of the docking frame 901. The docking frame 901 is inserted into the interior of the fitting hole. An excision assisting mechanism 8 is provided above the docking frame 901 on the adjusting tool holder 506. The excision assisting mechanism 8 includes a shaft frame 801, a pressing roller 813, and a pushing frame 806. Two shock-absorbing connecting frames 6 are provided inside the annular mounting rail 1. The shock-absorbing connecting frame 6 includes a connecting slider 601. The connecting slider 601 is slidably connected to the interior of the annular mounting rail 1. A hand-held rod 2 is fixedly connected to the top of the annular mounting rail 1.

[0034] Referring to Figures 1 - 4 , In a preferred embodiment, two fixing rods 3 are fixedly connected to the top of the annular mounting rail 1. The ends of the two fixing rods 3 are fixedly connected to the same motor frame 4. A driving motor 503 is fixedly connected to the interior of the motor frame 4. The output shaft of the driving motor 503 is fixedly connected to a driving shaft 505 through a coupling. The rotating disk 501 is fixedly connected to the outer sidewall of the driving shaft 505. The guardrail frame 504 is fixedly connected to the bottoms of the two connecting sliders 601. A fixed connection is provided between the rotating disk 501 and the two connecting sliders 601.

[0035] In a specific application scenario, when cutting the riser of the moving and static disk blanks, the staff carry the device to move to the riser. The infrared distance measuring sensor 507 is turned on to monitor the distance between the adjusting tool holder 506 and the riser, so as to control the pushing length of the cylinder 511, ensure that the distance that the cutting blade 7 is pushed into the riser is constant, realize the effective excision of the riser on the basis of reducing the damage of the cutting blade 7, avoid the cutting blade 7 from breaking due to too long horizontal pushing distance, protect the cutting blade 7, and eliminate potential safety hazards.

[0036] Specifically, when cutting a cylindrical riser with a larger upper part and a smaller lower part, if its diameter is less than the safe pushing distance of the cutting blade 7, directly adjust one of the cylinders 511 to drive the cutting blade 7 to advance forward to quickly realize the excision of the riser. If the diameter of the riser is 1 - 1.5 times the advancing distance of the cutting blade 7, first adjust one of the cylinders 511 to drive the cutting blade 7 to perform constant-distance advancement. After its reset, adjust the other cylinder 511 to drive the cutting blade 7 to perform constant-distance advancement, then the excision of the riser can be completed. The diameter of the cylindrical riser on the moving and static disk blanks is usually small and can be directly cut horizontally.

[0037] It should be noted that when removing the riser in an elliptical or other shape, the driving motor 503 is started. The driving motor 503 drives the two symmetrically distributed cutting blades 7 to rotate 360°. During the rotation process, the infrared distance sensor 507 always monitors the distance to ensure that the advancing distance of the cutting blade 7 is constant, thereby realizing the circular cutting of this type of riser. While the riser is efficiently removed, the damage degree of the cutting blade 7 is reduced, and the safety accident caused by the breakage of the cutting blade 7 is avoided.

[0038] In the present invention, end mounting blocks 509 are symmetrically distributed on the inner side wall of the guardrail frame 504, and the opposite sides of the two end mounting blocks 509 are fixedly connected to the same adjusting rail 502. Two symmetrically distributed distance adjusting slide rods 508 are slidably connected inside the adjusting rail 502. End blocks 510 are fixedly connected to the tops of the adjusting rail 502 close to the two end mounting blocks 509. Cylinders 511 are fixedly connected to the opposite sides of the two end blocks 510. The output end of the cylinder 511 is fixedly connected to one side of the adjacent distance adjusting slide rod 508. The adjusting tool rest 506 is fixedly connected to one side of the distance adjusting slide rod 508. Infrared distance sensors 507 are fixedly connected to the opposite sides of the two adjusting tool rests 506.

[0039] Refer to Figure 1 、 Figure 2 、 Figure 9 and Figure 10 In a preferred embodiment, mounting rods 904 are annularly distributed around the periphery of the docking frame 901 on the adjusting tool rest 506, and an embedding column 903 is fixedly connected to the end of each mounting rod 904. An embedding groove 905 is formed in the docking frame 901 at each embedding column 903. The embedding column 903 is inserted into the interior of the embedding groove 905. A fitting groove 910 is formed in the outer side wall of each embedding column 903 near the bottom end. Connecting spring rods 909 are fixedly connected to the inner side wall of the fitting groove 910 at equal intervals. An arc-shaped locking plate 908 is fixedly connected to the ends of the plurality of connecting spring rods 909. A surrounding groove 906 is formed in the docking frame 901 at each arc-shaped locking plate 908, and a communication hole 907 penetrating through to the interior of the surrounding groove 906 is formed in the outer side wall of the docking frame 901 at the surrounding groove 906. A pressing rod 902 is inserted into the interior of the communication hole 907.

[0040] Specifically, the cutting blade 7 will gradually wear out during use. When it loses its usability, it needs to be replaced. The staff presses each pressing rod 902, and through the pressing rod 902, the arc-shaped locking plate 908 is pressed into the fitting groove 910, so that the connecting spring rod 909 is in a compressed state. Then, the docking frame 901 is pressed from above, and the docking frame 901 is gradually pressed out of the fitting hole, thus completing the removal of the cutting blade 7. The docking frame 901 on the new cutting blade 7 is inserted into the fitting hole from below the fitting hole, and the embedding column 903 is docked with the embedding groove 905. After the embedding column 903 penetrates into the interior of the embedding groove 905, the arc-shaped locking plate 908 is pushed into the surrounding groove 906 by the connecting spring rod 909 in the compressed state, and the installation of the cutting blade 7 can be completed, which is convenient and efficient, and improves the convenience of installing the cutting blade 7.

[0041] Refer to Figure 1 、 Figure 3 and Figure 5 , in a preferred embodiment, a shock-absorbing spring I 603 is fixedly connected to one side of the connecting slider 601, and a compression block I 602 is fixedly connected to the end of the shock-absorbing spring I 603. A shock-absorbing spring II 605 is fixedly connected to the other side of the connecting slider 601, and a compression block II 606 is fixedly connected to the end of the shock-absorbing spring II 605. A same top docking rod 604 is fixedly connected to the tops of the compression block I 602 and the compression block II 606. The top docking rod 604 is located inside the annular installation rail 1. Both the compression block I 602 and the compression block II 606 are slidably connected to the inside of the annular installation rail 1. The distance between the compression block I 602 and the compression block II 606 is one-third of the circumference of the annular installation rail 1.

[0042] Specifically, during the operation of the drive motor 503, the vibration generated by the drive motor 503 has a greater impact on the stability of the cutting blade 7. By installing a shock-absorbing connecting frame 6 inside the annular installation rail 1, both the shock-absorbing spring I 603 and the shock-absorbing spring II 605 in the shock-absorbing connecting frame 6 are in a compressed state, and the compression block I 602 and the compression block II 606 are locked by a top docking rod 604. Thus, during the operation of the drive motor 503, the vibration intensity is weakened by the shock-absorbing spring I 603 and the shock-absorbing spring II 605, and the vibration intensity transmitted to the cutting blade 7 is reduced, improving the stability of the cutting blade 7 during use.

[0043] It should be noted that during the operation of the drive motor 503, the connecting spring rod 909 plays a buffering role to a certain extent, thereby improving the stability of the connection between the cutting blade 7 and the adjusting tool rest 506.

[0044] Refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 8, in a preferred embodiment, a positioning slide rail 804 is fixedly connected to one side above the infrared distance sensor 507 of the adjusting tool rest 506, and a follower slide bar 803 is slidably connected inside the positioning slide rail 804. A bottom of the follower slide bar 803 away from the positioning slide rail 804 is fixedly connected to an integrating rod 802. A bottom of the integrating rod 802 is fixedly connected to two pressing spring rods 810. A roller frame is fixedly connected to bottoms of the two pressing spring rods 810. Two ends of a pressing roller 813 are connected to two inner side walls of the roller frame through bearings.

[0045] In a specific application scenario, when the cutting blade 7 is pushed into the riser, the pressing roller 813 is blocked outside. As the cutting blade 7 continues to be pushed in, the pressing spring rod 810 above the pressing roller 813 is further compressed, and the follower slide bar 803 slowly slides in the positioning slide rail 804. The greater the pushing distance of the cutting blade 7, the greater the interaction force between the pressing roller 813 and the cutting blade 7. By squeezing the upper part of the cutting blade 7 through the pressing roller 813, it is ensured that the cutting blade 7 is not prone to the situation of the cutting surface rising and being crushed by extrusion during the cutting of the riser, further protecting the cutting blade 7.

[0046] Specifically, during the process of gradually pushing the cutting blade 7 into the riser, the extrusion between the pushing frame 806 and the riser becomes greater and greater, and the compression degree of the extrusion spring rod 812 gradually increases. The reaction force of the extrusion spring rod 812 drives the pushing frame 806 to push the upper part of the cutting position of the riser, so as to gradually push up the cut part of the riser, creating an angular difference between it and the cutting blade 7, reducing the extrusion damage suffered by the cutting blade 7, and at the same time, accelerating the separation between the riser and the dynamic and static disk blanks.

[0047] Refer to Figure 7 and Figure 8 , in a preferred embodiment, positioning rods 807 are fixedly connected to upper surfaces of the roller frame near both ends, and suspension rods 809 are fixedly connected to both ends of the bottom of the integrating rod 802. Bottoms of the two suspension rods 809 are fixedly connected to positioning rings 808. The positioning rods 807 are inserted into the positioning rings 808. Side rods 811 are fixedly connected to both sides of the positioning slide rail 804, and an end of each of the two side rods 811 is fixedly connected to the same rear support rod 805. Extrusion spring rods 812 are fixedly connected to one side of the rear support rod 805 at equal intervals, and a pushing frame 806 is fixedly connected to ends of the plurality of extrusion spring rods 812.

[0048] A method for removing the riser of a compressor dynamic and static disk blank, using a device for removing the riser of a compressor dynamic and static disk blank as described above, includes the following steps;

[0049] Step 1: When removing the riser of the moving and static disk blanks, the operator carries the equipment to the riser, and the infrared distance sensor 507 is turned on to monitor and adjust the distance between the tool rest 506 and the riser, so as to control the pushing length of the cylinder 511 and ensure that the distance the cutting blade 7 is pushed into the riser is constant;

[0050] Step 2: When removing a cylindrical riser with a larger upper part and a smaller lower part, if its diameter is less than the safe pushing distance of the cutting blade 7, directly adjust one of the cylinders 511 to drive the cutting blade 7 to advance forward to quickly remove the riser. If the diameter of the riser is 1 - 1.5 times the advancing distance of the cutting blade 7, first adjust one of the cylinders 511 to drive the cutting blade 7 to advance at a constant distance. After it resets, adjust the other cylinder 511 to drive the cutting blade 7 to advance at a constant distance to complete the removal of the riser;

[0051] Step 3: When removing an elliptical or other shaped riser, start the drive motor 503. The drive motor 503 drives the two symmetrically distributed cutting blades 7 to rotate 360°. During the rotation process, the infrared distance sensor 507 always monitors the distance to ensure that the advancing distance of the cutting blade 7 is constant, thereby realizing the circular cutting of this type of riser.

[0052] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

10. A method for removing the riser of the blank of the compressor moving and static disks, using a device for removing the riser of the blank of the compressor moving and static disks as described in claim 9, characterized in that, Including the following steps; Step 1: When cutting the riser of the dynamic and static disk blank, the staff carry the equipment by hand and move it to the riser. The infrared distance sensor (507) is turned on to monitor the distance between the adjusting tool rest (506) and the riser, so as to control the pushing length of the cylinder (511) and ensure that the distance of the cutting blade (7) pushed into the riser is constant; Step 2: When removing a cylindrical riser with a larger top and a smaller bottom, if its diameter is less than the safe pushing distance of the cutting blade (7), directly adjust one of the cylinders (511) to drive the cutting blade (7) forward to quickly remove the riser. If the diameter of the riser is 1 - 1.5 times the pushing distance of the cutting blade (7), first adjust one of the cylinders (511) to drive the cutting blade (7) for constant-distance pushing. After it resets, adjust the other cylinder (511) to drive the cutting blade (7) for constant-distance pushing to complete the removal of the riser. Step 3: When removing an elliptical or other-shaped riser, start the drive motor (503). The drive motor (503) drives the two symmetrically distributed cutting blades (7) to rotate 360°. During the rotation process, the infrared distance sensor (507) always monitors the distance to ensure that the pushing distance of the cutting blade (7) is constant, thereby achieving the circular cutting of this type of riser.
