Description

Technical Field

[0001] This utility model relates to the field of pipe mold processing technology, and in particular to a precision machining equipment for pipe molds. Background Technology

[0002] Pipe molds are essential tools for manufacturing various types of pipes and are widely used in numerous industries such as construction, chemical, automotive, and water conservancy. Through specific molding processes, they transform raw materials into pipe products with specific shapes, dimensions, and properties. In modern industrial production, the manufacturing precision of pipe molds plays a crucial role in the quality and performance of pipes.

[0003] During the production process, pipe molds need to be precision ground to remove burrs and ensure surface smoothness. However, during the precision grinding process, a large amount of high-temperature iron filings are generated. These iron filings may splash onto the precision-ground areas of the pipe mold and, upon contact, may cool and solidify on the surface of the pipe mold, affecting the precision grinding quality of the pipe mold. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: during the fine grinding of the surface, a large amount of high-temperature iron filings are generated. These iron filings may splash onto the area of ​​the pipe mold that has already been finely ground. Upon contact, they may cool and solidify on the surface of the pipe mold, affecting the fine grinding quality of the pipe mold. Therefore, this invention proposes a precision turning device for pipe molds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precision turning device for pipe molds includes a lathe, a feeding mechanism mounted on the lathe, a support base fixedly mounted on the lathe, and a precision grinding component mounted on the support base;

[0007] One end of the lathe is fixedly mounted with a fixing ring via a support frame. An isolation cover is fixedly mounted on the outer circular surface of the fixing ring at an angle. The isolation cover is located on one side of the precision grinding assembly. An annular cavity is formed inside the fixing ring. Multiple air outlets, all connected to the annular cavity, are equidistantly formed on the inner circular surface of the fixing ring. Gas nozzles are fixedly mounted in each of the multiple air outlets. An air collection assembly for collecting air into the annular cavity is mounted on the support frame.

[0008] Preferably, the fine grinding assembly includes a rotating disk rotatably mounted on the side of the support base, multiple mounting seats circumferentially mounted on the rotating disk, a movable block mounted on the mounting seat via an adjusting component, a support rod fixedly mounted on the movable block, a fine grinding block fixedly mounted on the support rod, and a drive assembly for driving the rotating disk to rotate. Each of the multiple mounting seats has a rectangular groove, and the movable block is slidably mounted in the rectangular groove.

[0009] Preferably, the adjusting component includes a threaded rod rotatably mounted in a rectangular groove and an adjusting block fixedly mounted at one end of the threaded rod, wherein the adjusting block is threadedly sleeved on the threaded rod.

[0010] Preferably, the drive assembly includes a gear ring fixedly sleeved on the rotating disk, a drive motor fixedly mounted on a support base, and a spur gear fixedly mounted on the output shaft of the drive motor, wherein the spur gear meshes with the gear ring.

[0011] Preferably, the gas collection assembly includes a gas collection cylinder fixedly mounted on a support frame, a movable plate slidably mounted in the gas collection cylinder, an outlet pipe fixedly mounted at one end of the gas collection cylinder, an inlet pipe fixedly mounted on the gas collection cylinder, and a transmission component for driving the movable plate to move. The end of the outlet pipe away from the gas collection cylinder is connected to an annular cavity. Both the inlet pipe and the outlet pipe are equipped with one-way valves.

[0012] Preferably, the transmission component includes a rotating shaft fixedly mounted on the side of the spur gear, a disc fixedly mounted on one end of the rotating shaft, a support rod rotatably mounted on the disc, and a push rod fixedly mounted on the side of the movable plate, wherein one end of the support rod is hinged to one end of the push rod.

[0013] The beneficial effects of this utility model are as follows:

[0014] During the precision grinding of the pipe mold, the gas collection component continuously fills the annular cavity with air and sprays it out through multiple gas nozzles, forming an air wall between the fixed ring and the pipe mold. This prevents the generated iron filings from passing through the gap between the pipe mold and the fixed ring. At the same time, the isolation cover can prevent iron filings from splashing onto the area of ​​the pipe mold after precision grinding and solidifying on the surface of the pipe mold, thus ensuring the precision grinding quality of the pipe mold.

[0022] 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.

[0023] Reference Figures 1-6 A precision turning device for pipe molds includes a lathe 1, a feeding mechanism 2 mounted on the lathe 1, a support base 3 fixedly mounted on the lathe 1, and a precision grinding component mounted on the support base 3. The feeding mechanism 2 is existing technology. The pipe mold is placed on the feeding mechanism 2, which can horizontally drive the pipe mold to move horizontally on the lathe 1. During the movement, the surface of the pipe mold is precision ground by the precision grinding component.

[0024] A fixing ring 5 is fixedly installed at one end of the lathe 1 via a support frame 4. An isolation cover 6 is fixedly installed on the outer circular surface of the fixing ring 5 at an angle. The isolation cover 6 is located on one side of the precision grinding assembly. An annular cavity is opened inside the fixing ring 5. Multiple air outlets that are all connected to the annular cavity are opened at equal intervals on the inner circular surface of the fixing ring 5. Gas nozzles 7 are fixedly installed in each of the multiple air outlets. An air collection assembly for collecting air into the annular cavity is installed on the support frame 4.

[0025] The fixing ring 5 is fitted onto the pipe mold. When the fine grinding component is fine grinding the pipe mold, the air collection component will continuously input air into the annular cavity, and then spray it out from multiple gas nozzles 7. The sprayed gas sprays onto the pipe mold, forming an air wall between the fixing ring 5 and the pipe mold, preventing the generated iron filings from passing through the gap between the pipe mold and the fixing ring 5. At the same time, the isolation cover 6 can prevent iron filings from splashing onto the area of ​​the pipe mold after fine grinding and solidifying on the surface of the pipe mold, thus ensuring the fine grinding quality of the pipe mold.

[0026] The precision grinding assembly includes a rotating disk 8 rotatably mounted on the side of the support base 3, multiple mounting seats 9 circumferentially mounted on the rotating disk 8, a movable block 10 mounted on the mounting seat 9 via an adjusting component, a support rod 11 fixedly mounted on the movable block 10, a precision grinding block 12 fixedly mounted on the support rod 11, and a drive assembly for driving the rotating disk 8 to rotate. Each of the mounting seats 9 has a rectangular groove, and the movable block 10 is slidably mounted in the rectangular groove. The adjusting component includes a threaded rod 13 rotatably mounted in the rectangular groove and an adjusting block fixedly mounted on one end of the threaded rod 13. The movable block 10 is threadedly sleeved on the threaded rod 13. The drive assembly includes a gear ring 14 fixedly sleeved on the rotating disk 8, a drive motor 15 fixedly mounted on the support base 3, and a spur gear 16 fixedly mounted on the output shaft of the drive motor 15. The spur gear 16 meshes with the gear ring 14.

[0027] The threaded rod 13 can be rotated by rotating the adjusting block, which in turn drives the moving block 10 to move within the rectangular groove, thereby driving the fine grinding block 12 to move and contact the pipe mold. The position of the fine grinding block 12 can be controlled, thereby controlling the fine grinding thickness. Then, the drive motor 15 is started, which drives the spur gear 16 to rotate. Since the spur gear 16 is meshed with the gear ring 14, the gear ring 14 can drive the rotating disk 8 to rotate, and the rotating disk 8 can drive multiple fine grinding blocks 12 to slide on the pipe mold, thereby achieving fine grinding of the pipe mold.

[0028] The gas collection assembly includes a gas collection cylinder 17 fixedly mounted on a support frame 4, a movable plate 18 sealed and slidably mounted inside the gas collection cylinder 17, an outlet pipe 19 fixedly mounted at one end of the gas collection cylinder 17, an inlet pipe 20 fixedly mounted on the gas collection cylinder 17, and a transmission component for moving the movable plate 18. The end of the outlet pipe 19 away from the gas collection cylinder 17 is connected to an annular cavity. One-way valves are installed in both the inlet pipe 20 and the outlet pipe 19. The transmission component includes a rotating shaft 21 fixedly mounted on the side of a spur gear 16, a disc 22 fixedly mounted at one end of the rotating shaft 21, a support rod 23 rotatably mounted on the disc 22, and a push rod 24 fixedly mounted on the side of the movable plate 18. One end of the support rod 23 is hinged to one end of the push rod 24.

[0029] When the drive motor 15 drives the spur gear 16 to rotate, it can drive the disc 22 to rotate through the rotating shaft 21. During the rotation, the disc 22 can move back and forth in the gas collecting cylinder 17 through the support rod 23 and the drive push rod 24, thereby driving the moving plate 18 to move back and forth in the gas collecting cylinder 17. The one-way valve installed in the air inlet pipe 20 only allows gas to enter the gas collecting cylinder 17 from the outside, and the one-way valve installed in the air outlet pipe 19 only allows gas to enter the annular cavity from the gas collecting cylinder 17. Therefore, when the moving plate 18 moves towards the push rod 24, outside air will enter the gas collecting cylinder 17 through the air inlet pipe 20. When the moving plate 18 moves away from the push rod 24, the air in the gas collecting cylinder 17 will enter the annular cavity, thereby causing the gas nozzle 7 to spray gas.

[0030] In this invention, the fixing ring 5 is sleeved on the pipe mold. When the fine grinding component is fine grinding the pipe mold, the air collection component will continuously input air into the annular cavity, and then spray it out from multiple gas nozzles 7. The sprayed gas sprays onto the pipe mold, forming an air wall between the fixing ring 5 and the pipe mold, preventing the generated iron filings from passing through the gap between the pipe mold and the fixing ring 5. At the same time, the isolation cover 6 can prevent iron filings from splashing onto the area of ​​the pipe mold after fine grinding and solidifying on the surface of the pipe mold, thus ensuring the fine grinding quality of the pipe mold.

[0031] 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.
