Description

Technical Field

[0001] This utility model relates to the field of deburring technology, specifically to a deburring device for the production of ductile iron pipe fittings. Background Technology

[0002] Ductile iron pipe fittings are a type of cast iron pipe fittings. The main material is ductile iron, which can withstand greater external forces and pressures, has good toughness, high elongation, is not prone to brittle fracture, can adapt to a certain degree of deformation and vibration, and has strong impact resistance. During the casting process, due to casting, demolding and other processes, burrs will be generated at the edges of the socket, flange interface, casting parting surface, etc., which need to be deburred.

[0003] In the existing technology, when deburring ductile iron pipe fittings, a lathe is usually used to machine the burrs on the circular interface (such as the pipe end) to ensure concentricity. The ductile iron pipe fitting needs to be fixed during deburring to prevent vibration from affecting the accuracy. However, it is not convenient to automatically adjust the deburring angle of the ductile iron pipe fitting. When deburring other positions, the ductile iron pipe fitting needs to be disassembled, adjusted and then fixed again. The efficiency of deburring ductile iron pipe fittings is low.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Please see Figures 1 to 4 A deburring device for producing ductile iron pipe fittings includes a base plate 1, a pipe-laying cylinder 2, positioning rings 3, positioning components, an adjusting frame 4, a deburring knife 5, and an adjusting component. The pipe-laying cylinder 2 is rotatably mounted on the upper side of the base plate 1 via a rotating seat, and a pipe-laying groove is provided on the inner bottom wall of the pipe-laying cylinder 2 to facilitate the stable placement of ductile iron pipe fittings of different specifications. Two positioning rings 3 are provided, which are moved towards each other inside the pipe-laying cylinder 2. The positioning component is installed between the two positioning rings 3. The adjusting frame 4 is raised and lowered on one side of the pipe-laying cylinder 2 via a support component. The deburring knife 5 is rotatably mounted on one side of the adjusting frame 4. The adjusting component is located between the deburring knife 5 and the adjusting frame 4. A collection frame 21 is detachably mounted on the pipe-laying cylinder 2. The collection frame 21 has a through-hole that matches the pipe-laying cylinder 2. By installing the collection frame 21 on the pipe-laying cylinder 2 through the through-hole, the debris generated during deburring can be collected, reducing the pollution of the working environment caused by debris falling.

[0046] refer to Figure 3 The adjustment assembly includes a first motor 6, an adjustment rod 7, an adjustment cylinder 8, and a second motor 9. The first motor 6 is installed on one side of the adjustment frame 4. The adjustment rod 7 is fixedly connected to the output end of the first motor 6 and is rotatably connected to the adjustment frame 4. The adjustment cylinder 8 is fixedly connected to the adjustment rod 7. The adjustment frame 4 has an adjustment port for the adjustment cylinder 8 to rotate. The second motor 9 is installed inside the adjustment cylinder 8, and the output end of the second motor 9 is fixedly connected to the deburring knife 5.

[0047] When the deburring angle needs to be adjusted according to the deburring requirements of ductile iron pipe fittings, the first motor 6 is started, causing the adjusting rod 7 to drive the adjusting cylinder 8 to rotate, so that the adjusting cylinder 8 drives the second motor 9 to rotate. At the same time, the second motor 9 is started, causing the second motor 9 to drive the deburring knife 5 to rotate, thereby enabling the deburring work of ductile iron pipe fittings.

[0048] refer to Figure 1 as well as Figure 2 The positioning assembly includes a positioning frame 10, a first electric cylinder 11, a positioning plate 12, and a positioning rod 13. The positioning frame 10 is located on one side of the tube 2. The first electric cylinder 11 is mounted on the positioning frame 10. There are two positioning plates 12, which are symmetrically connected to the output end of the first electric cylinder 11. A positioning strip 19 is fixedly connected to one side of the positioning plate 12. The positioning frame 10 has a positioning groove for the positioning strip 19 to slide, which improves the stability of the positioning plate 12 moving on the positioning frame 10. The positioning rod 13 is fixedly connected between each positioning plate 12 and the adjacent positioning ring 3. The tube 2 has a positioning port for the positioning rod 13 to slide, which can limit the movement of the positioning rod 13 and make the positioning rod 13 drive the positioning ring 3 to move stably.

[0049] After placing ductile iron pipe fittings of different specifications into the pipe-laying cylinder 2, the first electric cylinder 11 is activated, causing the two positioning plates 12 to move towards the two positioning rods 13. This allows the two positioning rings 3 to abut and clamp the ductile iron pipe fittings of different specifications, thereby improving the stability of the ductile iron pipe fittings placed in the pipe-laying cylinder 2 and also improving the stability of the ductile iron pipe fittings during deburring.

[0050] refer to Figure 3 The support assembly includes a support frame 14, a second electric cylinder 15, and a connecting frame 16. The support frame 14 is fixedly connected to the top of the base plate 1. The second electric cylinder 15 is mounted on the support frame 14. The connecting frame 16 is fixedly connected between the output end of the second electric cylinder 15 and the adjusting frame 4. A stabilizing frame 20 is fixedly connected to one side of the adjusting frame 4. A stabilizing groove is provided on the support frame 14 for the stabilizing frame 20 to slide, so that the adjusting frame 4 can move smoothly on the support frame 14, thereby allowing the height of the deburring knife 5 to be adjusted smoothly.

[0051] When the second electric cylinder 15 is started, the connecting frame 16 will drive the adjusting frame 4 to rise and fall. At the same time, the adjusting frame 4 will drive the first motor 6, the adjusting cylinder 8, and the second motor 9 to rise and fall, thereby allowing the deburring knife 5 to rise and fall, making it convenient to adjust the position of the deburring knife 5 according to the length of the ductile iron pipe fitting.

[0052] refer to Figure 1The rotating base includes a third motor 17 and a rotating rod 18. The third motor 17 is mounted on the base plate 1, and the output end of the third motor 17 is fixedly connected to the bottom end of the pipe-laying cylinder 2. Multiple rotating rods 18 are arranged in a circular array at the bottom end of the pipe-laying cylinder 2. The base plate 1 has a rotating opening for the multiple rotating rods 18 to rotate. When the pipe-laying cylinder 2 rotates, the multiple rotating rods 18 will also rotate in the rotating opening. This can improve the stability of the pipe-laying cylinder 2 in driving the ductile iron pipe fitting to rotate while supporting the pipe-laying cylinder 2.

[0053] Starting the third motor 17 can cause the pipe-laying cylinder 2 to rotate the ductile iron pipe fitting, so that different positions of the ductile iron pipe fitting can be rotated to the position of the deburring knife 5, thereby facilitating the deburring work of the ductile iron pipe fitting at different positions and improving the deburring efficiency of the ductile iron pipe fitting.

[0054] In summary, the process involves first placing the ductile iron pipe fitting to be deburred into the pipe-laying cylinder 2, then activating the first electric cylinder 11. This causes the two positioning plates 12 to move towards each other, along with the two positioning rods 13, and the two positioning rings 3 to clamp and position the ductile iron pipe fitting. Next, the second electric cylinder 15 is activated, causing the connecting frame 16 to move the adjusting frame 4 and the deburring knife 5. Once the deburring knife 5 has reached a suitable height, the first motor 6 is activated, causing the rotating rod 18 to rotate the adjusting cylinder 8, thus rotating the deburring knife 5 to a suitable deburring angle. The second motor 9 is then activated, allowing the deburring knife 5 to deburr the pipe opening of the ductile iron pipe fitting. Simultaneously, the third motor 17 is activated, causing the pipe-laying cylinder 2 to rotate the ductile iron pipe fitting. This allows for deburring at different positions on the pipe opening of the ductile iron pipe fitting, improving the deburring effect.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
