AI Technical Summary
The existing cold iron rust removal technology is difficult to effectively remove rust on the surface of slender iron rods, especially when it is blocked in the container, resulting in incomplete rust removal.
Vibration rust removal device is used to place the iron rod and matte into the vibration equipment at the same time. During the vibration process, the matte rubs against the surface of the iron rod to remove rust. The device includes a base, mounting plate, oil cylinder, elastic device, vibration bucket and vibration motor. The overturning of the vibration bucket is controlled through the oil cylinder to ensure that the matte fully wraps and rubs the iron rod.
It realizes efficient rust removal on the surface of the cold iron rod, with a simple structure and easy to use, and the matte is in a flowing state during vibration, increasing the friction effect and improving the rust removal efficiency.

The chills are mostly pure iron bars, or other iron bars with similar chemical compositions to the casting products. These iron bars are usually packed in boxes, and are easily rusted when exposed to air after opening. Therefore, in order to avoid the rusted part of the chill affecting the quality of the casting product, the chill needs to be rusted.

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.
[0017] like Figures 1 to 3 As shown, a cold iron rod rust removal device of the present embodiment includes a base 1 and a mounting plate 2, the middle part of the mounting plate 2 is hinged to the base 1, the base 1 is provided with a cylinder 3 for tilting the mounting plate 2 left and right, the mounting plate 2 is elastically connected to a vibrating bucket 5 through an elastic device 4, and the vibrating bucket 5 is fixed with a vibrating motor 6; the vibrating bucket 5 includes an abrasive area 51 and a sand unloading area 52, a detachable partition plate 7 is provided between the abrasive area 51 and the sand unloading area 52, and the bottom of the sand unloading area 52 is densely covered with leakage holes for facilitating the leakage of sand.
[0018] This embodiment can be used for rust removal of iron rods or other small metal parts. During operation, the iron rods used for cold iron and the frosting are poured into the abrasive area 51, and the vibration motor 6 is started. When the vibration bucket 5 vibrates, the frosting collides and rubs the surface of the iron rod to achieve the rust removal effect. In addition, in order to prevent the local frosting from being too little and unable to completely cover the iron rod, the present embodiment is provided with an oil cylinder 3 to make the vibration bucket 5 overturn left and right, so that the material in the vibration bucket 5 slides to the left or right during the vibration process, which not only makes the frosting completely cover the iron rod, but also makes the frosting in a flowing state, thereby increasing the friction effect. Among them, the automatic intermittent extension and retraction of the oil cylinder 3 is completed by the electromagnetic valve on its oil circuit, and the intermittent duration is approximately equal to the time required for the material to completely slide to one end of the vibration bucket 5, which is 15 minutes in this embodiment.
[0019] In order to further increase the coating effect of the grinding on the iron rod and improve the friction efficiency, a plurality of deceleration plates 8 are provided at the bottom of the abrasive area 51 to reduce the sliding speed of the material. The deceleration plates 8 are inverted angle irons.
[0020] The abrasive area 51 and the sand unloading area 52 are separated by a partition 7 that can be inserted up and down. For this purpose, the two side plates of the vibrating bucket 5 are provided with a slot plate 9 for inserting the partition 7, and the top of the slot plate 9 is threadedly connected with a screw for limiting the upward jump of the partition 7.
[0021] After rust removal is completed, the partition plate 7 is pulled out, and the vibration bucket 5 is tilted toward the sand unloading area 52 . During vibration, the ground sand leaks out from the leakage hole, and the cold iron rod remains in the sand unloading area 52 .
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, and for the convenience of describing the technical solution, the front, rear, left, right, top, middle, and bottom directions adopted are based on the settings in the accompanying drawings, rather than limiting the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
