Problems solved by technology

[0003]Large disk ring type shells are large in size and heavy in weight. Some large disk ring type shells have a diameter of up to 700mm and a weight of 50kg. Angle and multi-directional detection, cleaning, and repair of the wax spill to prevent dewaxing cracks are basically done by hand, which greatly increases the labor intensity of the workers and is very unfavorable to the health of the operators. At the same time, such an operation shell There is a high risk of defects

Embodiment 1

[0057] The outer diameter of the diffuser shell of a certain machine Height h=350mm, ring-shaped, three-pronged sprue, complex gating system structure, shell weight 42kg, number of wax outlets 7, operation requirements placement height H=1100mm, flip angle R=30°, 45°, 180°, in the actual shell inspection and preparation operations, it is very easy to cause handling bumps, and foreign objects fall into the cavity of the shell. Taking the inspection and preparation of 50 shells as an example, it takes an average of 2 to 3 people to operate for 3.5 hours to complete. Using this shell to pour 50 castings, the non-metallic inclusion rate is 10%.

[0058] By adopting the method described in the invention, a mold shell fixing and turning device is manufactured and used for mold shell inspection and mold shell preparation. The total height of the device base connected to the support rod h1+h2=1100mm, the outer diameter of the rotating tray The turning angle r=0°~180° can be realiz...

Embodiment 2

[0060] The outer diameter of the diffuser shell of a certain machine Height h=380mm, ring-shaped, three-pronged sprue, complex gating system structure, mold shell weight 47kg, number of wax discharge ports 8, operation requirements placement height H=1100mm, flip angle R=45°, 180°, In the actual shell inspection and preparation operations, it is very easy to cause handling bumps, and foreign objects fall into the cavity of the shell. Taking the inspection and preparation of 15 shells as an example, it takes an average of at least 2 to 3 people to operate for 3.5 hours to complete. Using this shell to cast 8 castings, the non-metallic inclusion rate is 5%.

[0061] By adopting the method described in the invention, a mold shell fixing and turning device is manufactured and used for mold shell inspection and mold shell preparation. The total height of the device base connected to the support rod h1+h2=1100mm, the outer diameter of the rotating tray It can realize the turning...

Embodiment 3

[0063] The outer diameter of the diffuser shell of a certain machine Height h=380mm, ring-shaped, three-pronged sprue, complex gating system structure, shell weight 50kg, number of wax discharge ports 9, operation requirements placement height H=1100mm, flip angle R=45°, 180°, In the actual shell inspection and preparation operations, it is very easy to cause handling bumps, and foreign objects fall into the cavity of the shell. Taking the inspection and preparation of 10 shells as an example, it takes an average of at least 2 to 3 people to operate for 3.5 hours to complete. Using this shell to pour 10 castings, the non-metallic inclusion rate is 5%.

[0064] By adopting the method described in the invention, a mold shell fixing and turning device is manufactured and used for mold shell inspection and mold shell preparation. The total height of the device base connected to the support rod h1+h2=1100mm, the outer diameter of the rotating tray It can realize the turning ang...

Abstract

The invention discloses a device and method for controlling defects of a large disc ring type shell. According to the device and method for controlling defects of large disc ring type shell, trundles are installed below a bottom frame in the device, a first supporting column and a second supporting column are fixed above the bottom frame, a transmission mechanism is fixed to the upper surface of the first supporting column, the power input end of the transmission mechanism is perpendicular to the length direction of the bottom frame, the power output end of the transmission mechanism is parallel to the length direction of the bottom frame; a retainer is arranged on the upper surface of the transmission mechanism; and the power output end is rotationally connected with one end of a second connecting rod, the upper surface of the second supporting column is rotationally connected with a first connecting rod, the first connecting rod and the second connecting rod are arranged in the direction parallel to the plane of the bottom frame, a rotating tray is fixed between the first connecting rod and the second connecting rod, and when the rotating tray is located at the horizontal position, the distance between the upper surface and the ground is the placing height of the large disc ring type shell, clamping pieces are arranged on the upper surface of the rotating tray in the circumferential direction, and the distance between the clamping pieces and the center of the rotating tray is equal to the maximum outer diameter of the shell. According to the method, the device is used for fixing the shell in a working area, then the rotating tray is turned over and locked, the shell is treated, and control over the shell defects can be conveniently and rapidly completed.

Description

technical field [0001] The invention belongs to the technical field of disc ring type shell defect control, in particular to a control device and method for large disc ring type shell defect. Background technique [0002] Large-scale disc-ring castings are indispensable large-scale hot-end parts of military and civil aero-engines, and large-scale disc-ring shells are an important part of such castings in the casting process. The molded part is molded, and the molten metal is poured after the shell is formed, and a large disc ring casting is obtained after cooling. The special application of large disk ring type shells requires high quality and zero defects. Therefore, in the manufacturing process of large disc-shaped shells, the large-scale disc-shaped shell inspection and large-scale disc-shaped shell preparation processes are particularly important as the last link before the large-scale disc-shaped shells are manufactured and poured. [0003] The large disk ring type sh...
