Improved flange structure for high-pressure double-roller sand making machine

Abstract

The utility model discloses an improved flange structure for a high-pressure double-roller sand making machine, which comprises a flange body, a plurality of flange through holes are arranged on the flange body, the plurality of flange through holes are uniformly distributed to enclose a circle, the circle and the flange body are concentrically arranged, threaded sleeves are fixed in the flange through holes, and the threaded sleeves are sleeved on the flange through holes. An inner threaded hole with two through ends is formed in the threaded sleeve; the thread bushing is welded in the flange through hole; one end of the threaded sleeve is provided with a step surface extending outwards, and the step surface is exposed out of the flange through hole; a thread bushing outer plane is arranged outside the thread bushing along the length direction; the number of the flange through holes and the number of the threaded sleeves are both sixteen. The flange has the advantages that the structure is novel, after the threaded holes are abraded and damaged, only the threaded sleeves at the corresponding positions need to be replaced, the whole flange body does not need to be replaced, cost is saved, and replacement is convenient and fast.

Description

Technical Field

[0001] The utility model relates to a component for a high-pressure double-roller sand making machine, in particular to an improved flange structure for a high-pressure double-roller sand making machine. Background Art

[0002] The existing flanges used in high-pressure roller sand making machines all have threaded holes directly processed on the flange body. Since the threaded holes are reused during use and installation, they are constantly worn and collided. As a result, once the threaded holes are damaged, they are difficult to repair and the entire flange body needs to be replaced, resulting in serious losses. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an improved flange structure for a high-pressure double-roller sand making machine in view of the deficiencies in the prior art.

[0004] In order to achieve the above purpose, the measures taken by the utility model are:

[0005] An improved flange structure for a high-pressure roller sand making machine comprises a flange body, a plurality of flange through holes are formed on the flange body, the plurality of flange through holes are evenly distributed to form a circle, the circle is concentrically arranged with the flange body, a threaded sleeve is fixed in the flange through hole, and an internal threaded hole with two ends passing through is arranged in the threaded sleeve;

[0006] The threaded sleeve is welded in the flange through hole;

[0007] One end of the threaded sleeve is provided with a step surface extending outward, and the step surface is exposed outside the flange through hole;

[0008] The outside of the threaded sleeve is provided with a threaded sleeve outer plane along the length direction;

[0009] The flange through holes and threaded sleeves are each provided with sixteen.

[0010] The utility model has the following beneficial effects: the structure is novel, and when the threaded hole is worn or damaged, only the threaded sleeve at the corresponding position needs to be replaced without replacing the entire flange body, thus saving costs and the replacement is also convenient and quick.

[0015] An improved flange structure for a high-pressure roller sand making machine includes a flange body 1, on which a plurality of flange through holes 101 are opened, and the plurality of flange through holes 101 are evenly distributed to form a circle, and the circle is concentrically arranged with the flange body 1, and a threaded sleeve 2 is fixed in the flange through hole 101, and the threaded sleeve 2 is provided with an internal threaded hole 201 penetrating at both ends. The flange through hole 101 is arranged near the outer edge of the flange body 1.

[0016] like Figure 1-4 As shown, if the internal threaded hole 201 is damaged due to wear and collision during use, only the corresponding threaded sleeve 2 needs to be replaced without replacing the entire flange body 1, thus saving costs. Replacement is also very convenient and quick.

[0017] The threaded sleeve 2 is welded in the flange through hole 101 .

[0018] One end of the threaded sleeve 2 is provided with a step surface 202 extending outward, and the step surface 202 is exposed outside the flange through hole 101 .

[0019] The outside of the threaded sleeve 2 is provided with a threaded sleeve outer plane 203 along the length direction.

[0020] The flange through holes 101 and the threaded sleeve 2 are both provided with sixteen.
