Description

Technical Field

[0001] This utility model relates to the field of ductile iron pipe casting, and in particular to a casting device for ductile iron pipe. Background Technology

[0002] Ductile iron pipe is a type of pipe made by adding a spheroidizing agent to molten iron and then using a centrifugal casting process. Graphite is distributed in the matrix in a spherical form. This structure significantly reduces stress concentration, thereby improving the toughness and strength of the material. A casting device is required for casting production of ductile iron pipe.

[0003] However, in the existing technology, due to the lack of effective pouring and feeding guidance and the inability to quickly cool down after pouring, it is impossible to guide the liquid base material during use. The slow flow of the liquid base material itself will result in uneven thickness of the ductile iron pipe during centrifugal molding. In addition, it is impossible to quickly cool down the ductile iron pipe during molding, which affects production efficiency due to the slow cooling speed.

[0004] In view of this, this paper studies and improves upon existing problems, providing a casting device for ductile iron pipes. The device's support angle is adjusted during liquid base material feeding to guide the material and ensure even distribution. This improves feeding efficiency and prevents uneven thickness of the ductile iron pipe during centrifugal forming. Simultaneously, highly fluid airflow is directed towards cooling fins to rapidly cool the ductile iron pipe during forming, reducing forming time and increasing production efficiency. The aim of this technology is to solve problems and enhance practical value. Utility Model Content

This invention, through a feeding angle adjustment mechanism and an air-cooled cooling mechanism, allows for adjustment of the support angle of the device during liquid material feeding, guiding the liquid material to be evenly distributed during feeding. This improves the feeding effect and avoids uneven thickness of the ductile iron pipe during centrifugal molding. Simultaneously, the highly flowing air blown onto the cooling fins rapidly cools the ductile iron pipe during molding, reducing molding time and improving production efficiency.

A hydraulic drive base 105 is movably connected to the middle of the rear end of the inner shaft rotating support plate 102. A rotating lifting support rod 106 is movably connected to the middle of the hydraulic drive base 105. When discharging liquid base material into the pouring device, the rotating lifting support rod 106 is first driven by the hydraulic drive base 105 to push the support base plate 201 for height adjustment. During height adjustment, the hydraulic... The hydraulic drive base 105 is angled, and at the same time, the rotating connecting pin 104 in the middle of the rotating bracket 103 adjusts the angle of the rotating centrifugal drive base 202 on one side of the support base plate 201. After adjustment, the casting device tilts, and the liquid base material is guided to quickly fill the centrifugal casting tank 4. After the centrifugal casting tank 4 is filled, the hydraulic drive base 105 resets the support base plate 201. The support angle of the device can be adjusted when the liquid base material is discharged, and the liquid base material is guided to be evenly distributed. This improves the discharge effect and avoids uneven thickness of the ductile iron pipe during centrifugal forming.

[0026] The adjustable casting drive assembly 2 includes a support base plate 201. A rotary centrifugal drive base 202 is fixedly connected to one side of the support base plate 201, and a fixed centrifugal drive base 203 is fixedly connected to the lower side of the support base plate 201. A drive bracket 204 is fixedly connected to the middle of both sides of the support base plate 201. A centrifugal drive wheel 205 is movably connected to the middle of the drive bracket 204. During centrifugal casting, the fixed centrifugal drive base 203 and the rotary centrifugal drive base 202 at the bottom of the support base plate 201 drive the centrifugal drive wheel 205 through the drive bracket 204. When the centrifugal drive wheel 205 rotates, it drives the centrifugal casting barrel 4 to rotate, thereby completing the casting of the ductile iron pipe.

[0027] Specifically, the air-cooled casting sleeve 3 includes an arc-shaped casting sleeve 301. An exhaust fan 302 is fixedly connected to the upper end of the arc-shaped casting sleeve 301. A dustproof plate 303 is detachably connected to the upper end of the exhaust fan 302. Side exhaust windows 304 are fixedly connected to the middle of both ends of the arc-shaped casting sleeve 301. The exhaust fan 302 draws low-temperature air from the outside into the interior of the arc-shaped casting sleeve 301. The low-temperature air is first filtered by the dustproof plate 303 and then pressurized and blown onto the annular heat dissipation fins 5 on the outer wall of the centrifugal casting barrel 4 for air-cooling. The heat-exchanged air is discharged through the side exhaust windows 304 of the arc-shaped casting sleeve 301. The highly flowing air blows onto the cooling fins, which quickly cools down the ductile iron pipe forming process, reducing the forming time and improving production efficiency.

[0028] Specifically, there are two sets of centrifugal drive wheels 205. The middle parts of the fixed centrifugal drive base 203 and the rotary centrifugal drive base 202 are movably connected to the middle parts of the centrifugal drive wheels 205 through the drive bracket 204. The fixed centrifugal drive base 203 and the rotary centrifugal drive base 202 start synchronously. The drive teeth on the fixed centrifugal drive base 203 and the rotary centrifugal drive base 202 engage with the drive chain in the middle of the drive bracket 204, and synchronously drive the centrifugal drive wheels 205 in the middle of the drive bracket 204.

The upper end of the arc-shaped casting sleeve 301 is movably connected to the outer wall of the centrifugal casting tank 4 through the limiting roller. When the centrifugal casting tank 4 rotates rapidly, the limiting roller inside the arc-shaped casting sleeve 301 restricts its rotation to ensure stability.

[0031] Specifically, the two sides of the rotating bracket 103 are movably connected to the middle of both ends of the rotating centrifugal drive base 202 via rotating connecting pins 104. The rotating connecting pins 104 in the middle of the rotating bracket 103 restrict the angle adjustment of the rotating centrifugal drive base 202.

[0032] Specifically, one end of the rotary lifting support rod 106 is detachably connected to the lower side of the support base plate 201, and the upper end of the support frame 101 is movably connected to the lower end of the support base plate 201. The support frame 101 provides support for the bottom of the support base plate 201, and the rotary lifting support rod 106 adjusts the height of one side of the support base plate 201.

[0033] Working principle: When casting ductile iron pipes, during the liquid base material feeding of the casting device, the hydraulic drive base 105 drives the rotary lifting support rod 106 to push the support base plate 201 for height adjustment. During height adjustment, the hydraulic drive base 105 adjusts its angle. Simultaneously, the rotary connecting pin 104 in the middle of the rotary bracket 103 adjusts the angle of the rotary centrifugal drive base 202 on one side of the support base plate 201. After adjustment, the casting device tilts, guiding the liquid base material and quickly filling it into the centrifugal casting tank 4.

Reset operation can be performed, and the support angle of the device can be adjusted to guide the liquid base material to be evenly distributed during feeding. Through feeding effect and to avoid uneven thickness of ductile iron pipe during centrifugal forming, the exhaust fan 302 draws the external low-temperature air into the interior of the arc-shaped casting sleeve 301. The external low-temperature air is first filtered by the dustproof plate 303 and then pressurized and blown onto the annular heat dissipation fins 5 on the outer wall of the centrifugal casting barrel 4 for air cooling. The heat exchanged air is discharged through the side exhaust window 304 of the arc-shaped casting sleeve 301. The highly flowing air blows onto the cooling fins to quickly cool the ductile iron pipe forming, reduce forming time and improve production efficiency.
