Description

Technical Field

[0001] The invention relates to the technical field of casting devices, and in particular to a casting mechanism and a casting device for automobile bearing production. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. In the automotive industry, bearings also play a vital role. When producing bearings, the bearing rings and balls need to be produced separately and then assembled. The strength of the bearing ring has a great influence on the performance of the bearing. When producing bearing rings, centrifugal casting is usually used. This method helps to remove gas and inclusions in liquid metal; affects the crystallization process of the metal, thereby improving the mechanical and physical properties of the casting.

Therefore, the automobile bearing production casting device should also have the effects brought by the automobile bearing production casting mechanism, which will not be elaborated one by one.

[0049] Working principle: When pouring, first pour the raw material into the feed chamber 22, then step on the pedal 6 to compress the second spring 66, lower the lifting rod 61, and pull the rotating tube 65 and the rotating rod 28, so that the rotating rod 26 drives the cam 27 to rotate, and the cam 27 is separated from the blocking rod 24. Under the action of gravity, the blocking rod 24 slides downward to block the outlet of the quantitative chamber 23, so that the quantitative chamber 23 is connected with the feed chamber 22, and the raw material falls into the quantitative chamber 23. When the pedal 6 is stepped on, the first spring 63 drives the inclined block 62 to move downward, so that the inclined block 62 is separated from the sliding frame 4, and at the same time When the screw block 64 is driven to slide down, the screw block 64 is separated from the screw rod 41. Because the tension spring 42 is in a stretched state, the sliding frame 4 slides under the resetting action of the tension spring 42 and presses the feed end cover 32. At the same time, the sliding frame 4 pushes the discharge end cover 31 through the fixing ring 52 to push out the contents of the centrifuge tube 3. Then, the pedal 6 is released and the drive motor 7 is started. When the pedal 6 is released, the pedal 6 rises under the action of the second spring 66 and drives the inclined block 62 and the screw block 64 to reset. After the screw block 64 is reset, it is threadedly connected with the screw rod 41. At this time, the drive motor 7 is started. The centrifuge tube 3 drives the gear ring 35 to rotate, and through the gear 12, the polygonal rod 43 rotates, and the screw 41 rotates accordingly. Under the action of the threaded block 64, the screw 41 resets the sliding frame 4, and at the same time resets the feed end cover 32 and the discharge end cover 31, and stretches the tension spring 42 until the sliding frame 4 moves to the inclined block 62, and under the action of the first spring 63, the inclined block 62 limits the sliding frame 4. At this time, the screw 41 slides to disengage from the threaded block 64, so that even if the screw 41 continues to rotate, it will not affect the threaded block 64. At the same time, after releasing the pedal 6, the lifting rod 61 rises under the action of the second spring 66, and the protrusion rotates and resets. At this time, the blocking rod 24 rises, blocks the entrance of the quantitative chamber 23, and opens the outlet of the quantitative chamber 23, so that the material flows into the centrifuge tube 3 along the tube. At this time, the centrifuge tube 3 is in a rotating state, and the raw materials flowing in are centrifugally cast and shaped. After the casting is completed, the driving motor 7 stops rotating, so that the centrifuge tube 3 stops rotating, and the pedal 6 is stepped on to eject the finished product that has been cast and shaped, and the raw materials are input into the quantitative chamber 23 through the feed chamber 22. The principle is the same as above.

[0050] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
