Description

Technical Field

[0001] The invention relates to the technical field of pump volutes, in particular to a cutting device for producing volutes. Background Art

[0002] The volute is a spiral shell structure, mainly used in fluid machinery equipment to collect, guide and regulate the flow of fluid. It is designed to evenly distribute the fluid discharged from the rotating impeller and effectively convert the kinetic energy of the fluid into pressure energy. Among them, the pump volute is a specific type of volute, which is mainly used in centrifugal pumps, and is divided into metal pumps and plastic pumps according to different use environments. The volute is the abbreviation of the volute water chamber. Its appearance is very similar to a snail shell, so it is usually referred to as the volute. The metal pump volute is the metal poured into the mold. The plastic pump volute is the plastic material filled into the mold. After the pump volute is produced, there will be residual material at the injection port, which needs to be cut to ensure the quality and appearance of the product.

[0004] Although the device can adapt to different pump volutes to clamp them, it cannot monitor the clamping force, which can easily damage the plastic pump casing. In addition, the device can only cut the injection port or the burr residue, but the burrs after cutting cannot be removed and need to be cleaned separately later, which is inconvenient to operate.

[0048] Working principle: Step 1: After connecting to the external power supply, connect the external dry ice cleaning machine through the connecting pipe 206, then place the pump housing 4 on the upper end surface of the housing 1, and control the second electric telescopic rod 103 to extend through the control panel 2 to drive the first fixed frame 104 to move. When the piston rod 107 contacts the pump housing 4, the piston rod 107 moves in the cylinder 108, and the gas in the cylinder 108 enters the second cavity 110. As the piston rod 107 clamps the pump housing 4, the air pressure in the second cavity 110 increases, and the barometer 105 begins to change. When the barometer 105 reaches a certain value, the second electric telescopic rod 103 stops extending to prevent damage to the pump housing 4.

[0049] Step 2: After the pump housing 4 is clamped, the height of the pump housing 4 can be adjusted by the first electric telescopic rod 101, so that the pump housing 4 moves to the bottom of the cutting blade 209, and the cutting blade 209 cuts its burrs.
