Embodiment 1

[0047] Combine Figure 1~3 , The box turning and sanding-out system for casting wear-resistant parts of this embodiment includes a box turning device and a sanding device 7. The flask turning device includes a rotating arm 1, a frame 2, a telescopic arm 3, a base 5, and a flask 6. The frame 2 is fixed on the base 5, the rotating arm 1 is hinged to the frame 2, and the telescopic arm 3 and the rotating arm 1 Connected, the telescopic arm 3 is used to push the rotating arm 1 to rotate with the hinge point of the rotating arm 1 and the frame 2 as the center of the circle, and the rotating arm 1 is used to install the sand box 6. The flask turning device in this embodiment is specifically: the rotating arm 1 includes an upper flask cover 109 and a lower rotating arm main body. The rotating arm main body includes a lower bottom plate and a side plate. The lower end of the side plate is vertically fixed to the lower bottom plate. The upper end of the side plate is fixedly connected ...

Embodiment 2

[0055] The structure of the box turning-out system for casting wear-resistant parts of this embodiment is basically the same as that of Embodiment 1, and the difference is that: in the sand box turning device, the pushing arm 401 and the pushing arm 402 are both hydraulic cylinders;

[0056] In the screenout device 7, the angle between the baffle plate 709 and the vertical is 45°; the aperture of the through hole on the sieve plate 703 between the material input end 711 and the first baffle plate is 10mm, and the first baffle plate and the The through hole diameter of the sieve plate 703 between the two blocking plates is 15 mm, and the through hole diameter of the sieve plate 703 between the second blocking plate and the material output end 712 is 20 mm.

Embodiment 3

[0058] The structure of the turning box screenout system for casting wear-resistant parts of this embodiment is basically the same as that of Embodiment 1, and the difference lies in that: in order to ensure that small particles of metal impurities are not mixed into the recovered molding sand, the material input end 711 There is a magnetic separator at the top. The magnetic separator is used to magnetically separate the molding sand that enters the conveying tank 701 to remove small particles of metal impurities in the molding sand; in order to improve the working environment on site and avoid air pollution, it is also used above the conveying tank 701 A dust hood is provided. The dust hood plays a role of absorbing the dusty air above the conveying trough 701. At the same time, the newly cast castings not only have high heat, but also emit some toxic and harmful gases. The effect of removing toxic and harmful gases.

Abstract

The invention discloses a box turnover and sand strip system for casting wear-resisting parts and belongs to the field of wear-resisting part casting equipment. The system comprises a sand box turnover device and a sand strip device. The sand box turnover device comprises a rotating arm, a rack, a telescopic arm, a base and a sand box. The rack is fixed to the base. The rotating arm is hinged to the rack. The telescopic arm is connected with the rotating arm. The telescopic arm is used for pushing the rotating arm and rotates with a hinge point of the rotating arm and the rack as the circle center. The rotating arm is used for installing the sand box. The sand strip device is located at one side of the sand box turnover device. The sand strip device comprises a conveying groove, a supporting mechanism, a vibrating mechanism and a conveying groove base. The conveying groove is installed in the conveying groove base through the supporting mechanism. The conveying groove is connected with the vibrating mechanism. The vibrating mechanism is used for conveying materials in the conveying groove from the material input end of the conveying groove to the material output end of the conveying groove in a vibrating mode. The system mainly has a function of carrying out sand box turnover operation safely and reliably, and is suitable for carrying out sand strip operation on a large scale.

Description

Technical field [0001] The invention relates to the field of casting equipment for wear-resistant parts, and more specifically, to a box-turning and sand-out system for casting of wear-resistant parts. Background technique [0002] Wear-resistant parts are generally produced by casting. Common wear-resistant parts are mixing blades and hollow grinding balls. In casting production, there are many ways to flip the flask, which can be roughly divided into two categories: floating flip and ground flip. For the suspended flip, the flipping machine needs to be used to suspend the sand box to achieve its flip. For thicker or larger castings, when the box is turned during the mold clamping process, due to the large size of the sand box, the chain of the flipper is easy to be Pull off, there is a greater security risk. [0003] In order to solve the problem that the chain of the turning machine is easy to be broken and there is a large safety hazard, related technical solutions have been ...
