Description

Technical Field

[0001] The utility model relates to the field of ductile iron pipe fitting processing, in particular to a processing device for producing ductile iron castings. Background Art

[0002] Ductile iron is a high-strength cast iron material with comprehensive properties close to those of steel. This casting process uses rare earth magnesium alloy as a spheroidizer. Spheroidizing and inoculating treatments produce spheroidal graphite, which effectively improves the mechanical properties of cast iron, thereby achieving a higher strength than carbon steel.

[0003] Existing pipe fittings cast using ductile iron have a wide range of applications, including the following types: injection molded pipe fittings, plastic coated or rotationally molded pipe fittings, drainage ductile pipes, etc. In the process of using ductile iron to process pipe fittings, the pipe fittings need to be treated with anti-corrosion after processing, and the anti-corrosion layer is sprayed to extend the service life of the pipe fittings. However, in the existing process of spraying the inner wall of the pipe fitting, when the anti-corrosion material is just sprayed on the inner wall, the adhesion of the anti-corrosion layer is not so fast, causing the anti-corrosion material to slide down along the inner wall of the pipe fitting, so that in the subsequent spraying process, the anti-corrosion material cannot be evenly covered on the inner wall of the pipe fitting, causing the weak area to be more susceptible to erosion by the external environment, and the pipe fittings will corrode prematurely. Utility Model Content

[0004] The purpose of the utility model is to provide a processing device for the production of ductile iron castings, which effectively solves the problem that during the process of spraying the inner wall of ductile iron pipe fittings, the anti-corrosion material slides on the inner wall of the pipe fitting, resulting in insufficient thickness of the anti-corrosion layer at some positions of the inner wall of the pipe fitting, making it more susceptible to erosion by the external environment and causing premature corrosion.

[0005] The technical solution of the utility model is as follows:

[0006] A processing device for producing ductile iron castings, comprising a bottom plate, a positioning plate is provided on one side of the top of the bottom plate, a power rod extending transversely to the inside of the pipe fitting is provided on the side wall of the positioning plate, a turntable is symmetrically provided on the power rod, a pipeline delivery box is provided between two of the turntables, a nozzle evenly distributed vertically downward is provided at the bottom of the pipeline delivery box, a liquid inlet pipeline is provided on the side of the pipeline delivery box close to the positioning plate, a mounting plate 1 is provided on the outer wall of the turntable, a brush roller is provided between two of the mounting plates 1, the brush roller is vertically arranged with the nozzle, and a scraper plate connected by a mounting plate 2 is provided between the brush roller and the nozzle;

When the pipe fitting is positioned, the clamping opening is attached to the outer wall of the pipe fitting, and a rubber pad is provided on the top of the clamping opening.

[0010] Furthermore, the scraping plate is inclined near the bottom of the inner wall of the pipe, and a horizontal baffle is provided on the side of the scraping plate away from the nozzle.

[0011] Furthermore, the support sliding assembly includes support wheels symmetrically arranged on the outer wall of the pipe and evenly distributed along the length direction, and cross plates are provided on the outer sides of the two end faces of the support wheels, one of the cross plates is provided with support plates evenly distributed and vertically connected to the bottom plate.

[0012] Furthermore, the support wheels on both sides are symmetrically inclined with respect to each other, and the wheel surfaces of the support wheels are perpendicular to the outer wall of the pipe.

[0013] Furthermore, the supporting sliding assembly also includes a horizontal screw rod, which is located between the pipe fitting and the base plate and connected to the positioning plate.

[0014] The advantages of the utility model are:

[0015] 1. The utility model arranges a power rod inside the ductile iron pipe fitting, and the power rod is connected to a nozzle, a scraping plate and a brush roller through a connecting piece. When the nozzle sprays the anti-corrosion material on the outer wall of the pipe fitting, the power rod is rotated to make the scraping plate scrape the anti-corrosion material flat. After the scraping plate scrapes the coating material flat, the brush roller will further adhere to the inner wall of the pipe fitting to roll and brush, thereby preventing the coating material from sliding down on the pipe wall by rolling and brushing again after the scraping plate scrapes it flat, thereby improving the uniformity of brushing the inner wall of the ductile iron pipe fitting.

[0016] 2. The utility model provides a baffle on the scraper, so that in the initial state, when the scraper plate is scraping the coating material, the baffle can effectively prevent the coating material from moving on the scraper plate, so that the coating material can finally completely cover the inner wall of the pipe.

When the motor 2 is started, the push plate pushes the side wall of the pipe fitting to move on the support wheel. When the pipe wall thickness at the other end of the support wheel is inserted into the slot in the block, the pipe fitting is fixed. During the anti-corrosion treatment of the inner wall of the pipe fitting, the pipe fitting can be effectively prevented from moving, thereby improving stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] A pipe conveying box 6 is provided between the two turntables 5. The bottom of the pipe conveying box 6 is provided with nozzles 7 evenly distributed vertically downward.

[0026] The outer wall of the turntable 5 is provided with a mounting plate 9 , and a brush roller 10 is provided between the two mounting plates 9 . When the pipe fitting 3 is placed, the brush roller 10 just fits on the inner wall of the pipe fitting 3 .

[0027] The brush roller 10 is vertical to the nozzle 7, and a scraper plate 12 connected by a mounting plate 11 is provided between the brush roller 10 and the nozzle 7. The scraper plate 12 is inclined near the bottom of the inner wall of the pipe 3. After the nozzle 7 has sprayed all the anti-corrosion paint, the scraper plate 12 can be rotated to scrape the paint on the inner wall of the pipe 3, so that the paint is evenly covered on the inner wall of the pipe 3.

[0028] A motor 13 and a storage box 14 are provided on the side of the positioning plate 2 away from the pipe 3. The motor 13 is connected to the power rod 4. The liquid inlet pipeline 8 is inserted into the storage box 14. The anti-corrosion paint is stored in the storage box 14 and transported to the nozzle 7 through the liquid inlet pipeline 8.

[0029] A clamping block 15 is provided on one side of the positioning plate 2 close to the pipe fitting 3. The vertical section of the clamping block 15 is arc-shaped. A clamping notch 16 is provided on the side of the clamping block 15 facing the pipe fitting 3. When the pipe fitting 3 is positioned, the clamping notch 16 is attached to the outer wall of the pipe fitting 3. When the push plate 24 pushes the pipe fitting 3 to move, when the other end of the pipe fitting 3 touches the clamping block 15, the clamping notch 16 is just stuck on the outer wall of the pipe fitting 3.

[0030] A rubber pad 17 is provided on the top of the bayonet 16 , and the rubber pad 17 can provide a certain degree of protection for the pipe fitting 3 .

[0031] The scraping plate 12 is inclined near the bottom of the inner wall of the pipe 3, and a horizontal baffle 18 is provided on the side of the scraping plate 12 away from the nozzle 7. Through the baffle 18, when the scraping plate 12 scrapes the coating material, the baffle 18 can effectively prevent the coating material from moving upward on the scraping plate 12.

[0032] A supporting sliding assembly for fixing the pipe fitting 3 is provided between the base plate 1 and the pipe fitting 3, and the supporting sliding assembly includes supporting wheels 19 symmetrically arranged on the outer wall of the pipe fitting 3 and evenly distributed along the length direction, and cross plates 20 are provided on the outer sides of the two end faces of the supporting wheels 19, and one of the cross plates 20 is provided with supporting plates 21 evenly distributed and vertically connected to the base plate 1.

[0033] The supporting wheels 19 on both sides are symmetrically inclined with each other, and the wheel surfaces of the supporting wheels 19 are perpendicular to the outer wall of the pipe 3 , so that the pipe 3 can slide on the supporting wheels 19 .

[0034] The supporting sliding assembly also includes a horizontal screw rod 22, which is located between the pipe fitting 3 and the base plate 1 and connected to the positioning plate 2. A sliding block 23 is provided on the horizontal screw rod 22, and the sliding block 23 slides on the horizontal screw rod 22 when the horizontal screw rod 22 rotates.

[0035] A push plate 24 is provided on the top of the sliding block 23, and the top of the push plate 24 is arc-shaped, which pushes the side wall of the pipe fitting 3 to move toward the block 15. Through the set push plate 24, the push plate 24 pushes the side wall of the pipe fitting 3 to move on the support wheel 19. When the pipe wall thickness at the other end of the support wheel 19 is inserted into the bayonet 16 in the block 15, the pipe fitting 3 is fixed, and the movement of the pipe fitting 3 can be effectively prevented during the anti-corrosion treatment of the inner wall of the pipe fitting 3. A motor 25 is provided on the same side of the positioning plate 2 and the motor 1 13, and the output shaft of the motor 25 is connected to the horizontal screw rod 22.

[0036] Detailed usage and effects of the above embodiments:

[0037] When the pipe fitting 3 needs to be sprayed with anti-corrosion, the pipe fitting 3 is first placed on the supporting wheel 19, the motor 25 is started, and the horizontal screw rod 22 rotates, so that the sliding block 23 drives the push plate 24 to contact the side wall of the pipe fitting 3, and pushes the pipe fitting 3 to move on the supporting wheel 19. When the other end of the pipe fitting 3 contacts the clamping block 15, the clamping mouth 16 is just clamped on the outer wall of the pipe fitting 3. At this time, the rotation is stopped to fix the pipe fitting 3.

[0038] At this time, the power rod 4 is located inside the pipe 3, and the liquid coating in the storage box 14 is extracted, passed through the liquid inlet pipeline 8, and sprayed on the inner wall of the pipe 3 through the nozzle 7. The amount of coating sprayed by the nozzle 7 is the amount of coating on the inner wall of the pipe 3. The spraying stops after the spraying. At this time, the coating is all on the inner wall of the pipe 3. The motor 13 is started to drive the power rod 4 to rotate. There is a gap between the scraper plate 12 and the inner wall of the pipe 3. The scraper plate 12 will contact the coating during rotation and slowly drive the coating to be smoothed on the inner wall of the pipe 3. After the scraper plate 12 scrapes the coating material, the brush roller 10 attached to the inner wall of the pipe 3 will also roll and smooth the coating smoothed by the scraper plate 12. After being scraped by the scraper plate 12, the coating adheres to the inner wall of the pipe 3 and slides, resulting in uneven coating, thereby completing the anti-corrosion processing of the entire inner wall of the pipe 3.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
