Description

Technical Field

[0001] The utility model relates to the technical field of riser cutting, and particularly relates to a riser cutting device for cast iron parts. Background Art

[0002] When forming cast iron parts, it is usually necessary to use risers for feeding. After the cast iron parts solidify and form, the risers need to be cut. Due to the wide variety and unevenness of cast iron parts, if a common pipe cutting device is directly used for cutting, it is impossible to ensure smooth cutting, the stability of the cast iron parts during cutting is poor, and there are also safety hazards such as high-temperature tool breakage.

[0003] In the prior art, a spray device is usually set to cool down during cutting. For example, in the patent with the publication number CN211101560U, the device for removing the water riser of cast iron parts disclosed therein can quickly cool the cutting position through a spray head to prevent tool breakage caused by too high a temperature of the cutting tool. Further, when the cutting tool is driven by a telescopic rod to move downward to cut the cast iron part, the first support plate is simultaneously moved to squeeze the pressing plate downward, and the pressing plate drives the ejector rod and the rubber pressing plate to move downward, so that the rubber pressing plate can fix the cast iron part to be processed and prevent the cast iron part from shaking and shifting during cutting.

[0004] However, since the products produced are different, and thus the cast iron parts are different, the clamping method using a support plate and a pressing plate cannot ensure the stability of the special-shaped cast iron parts during cutting.

[0005] Based on the above description, there is an urgent need for a riser cutting device with a wide application range, strong fixing property and high safety. Summary of the Utility Model
