Embodiment 1

[0047] combine Figure 1~3 , the present embodiment of the wear-resistant casting casting sand removal system includes a sand box turning device and a sand removal device 7 . The sand box overturning device includes a rotating arm 1, a frame 2, a telescopic arm 3, a base 5 and a sand box 6, the frame 2 is fixed on the base 5, the rotating arm 1 is hinged on the frame 2, 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 a circle, and the rotating arm 1 is used to install the sand box 6 . In this embodiment, the sand box turning device is specifically: the rotating arm 1 includes an upper sand box cover 109 and a lower rotating arm main body, the rotating arm main body includes a lower bottom plate and a side plate, and the lower end of the side plate is vertically fixed on the lower bottom plate, The upper end of side plate is fixed...

Embodiment 2

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

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

Embodiment 3

[0058] The structure of the flipping and desanding system for wear-resistant parts casting in this embodiment is basically the same as that of Embodiment 1, the difference is that in order to ensure that the recovered molding sand is not mixed with small particles of metal impurities, at the material input end 711 There is a magnetic separator above, and the magnetic separator is used to magnetically separate the molding sand entering 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, there is also a There is a dust collection cover, which can absorb the dusty air above the conveying trough 701. At the same time, the castings that have just been cast not only have high heat, but also emit some toxic and harmful gases. Toxic and harmful gas pumping effect.

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, relates to a box-turning and desanding system for casting wear-resistant parts. Background technique [0002] Wear-resistant parts are generally produced by casting, and common wear-resistant parts are stirring blades, hollow grinding balls, etc. In foundry production, there are many ways to turn the sand box, which can be roughly divided into two categories: suspension turning and ground turning. For suspended flipping, it is necessary to use a flipping machine to suspend its sand box, and then realize its flipping. For thicker or larger castings, when flipping the box during the mold clamping process, due to the large size of the sand box, the chain of the flipping machine is easily damaged. If it is pulled off, there is a greater potential safety hazard. [0003] In order to solve the problem that the chain of the turning machine is easily brok...
