Description
Technical field
The present invention relates to casting industry equipment technical field, relate in particular to a kind of casting sand and the automatic separating and reclaiming device of shot.
Background technology
Casting technique can be divided into gravitational casting, compression casting and sand casting.The adaptability of sand casting is very wide, and the Modeling Material used due to sand casting is cheap and easy to get, and Casting mold manufacturing is easy, price advantage is particularly outstanding, to the single-piece production of foundry goods, produce by batch and produce in a large number and all can adapt to, for a long time, be the basic technology in Foundry Production always.At present, in whole castings production, the foundry goods of 60 ~ 70% is produced with sand mold.
Sand casting adopts the Modeling Material based on sand, each sand mold can only use once, in a large amount of production, produce thousands of individual identical foundry goods, need the sand mold making same quantity, productivity ratio low is like this difficult to meet the needs of production, but also can bring series of problems, as large in Modeling Material consumption, molding sand can produce dust, contaminated environment, worsens working condition, needs complete molding sand process and transporting equipment; Easily produce scab defect after cast, affect surface finish of casting etc.If adopt the quartz sand of binder free or shot to do Modeling Material, replace the effect of binding agent by gravity, negative pressure, magnetic field force, this type of Modeling Material then can Reusability, and without the need to sand preparing machine, formative method also there occurs basic change.
After pouring technology in casting process completes, enter the knockout treatment process of foundry goods.Knockout is divided into artificial knockout and mechanical knockout, and in non_mechanical foundry shop, foundry goods is poured into a mould on ground, and be generally at cast place knockout on the spot, workman's sledgehammer and drill rod hit sandbox and disclose molding sand, also has and adopts pneumatic shovel to coordinate aforesaid operations to carry out knockout; Workshop with good conditionsi can adopt the pneumatic knockout hook of suspension or vibrating shakeout to lift up into row knockout, knockout working condition is poor on the spot, productivity ratio is low, be only applicable to the foundry of unit small lot batch manufacture, on mechanical production line, knockout is concentrated in usual employing mechanization, foundry goods need be placed on viberating knock-out machie and by vibrations, sand be fallen.
But traditional mechanical type knockout, is only applicable to use molding sand to do the casting of Modeling Material.And other casting technique improved, during as added the moulding of magnetic shot in the process of sand casting, traditional mechanical shakeout machinery has been unfavorable for being separated and recycling of molding sand and shot.
Summary of the invention
The object of the invention is to overcome prior art Problems existing, providing one can solve casting sand and the automatic separating and reclaiming device of shot in novel casting technique, enhancing productivity, reduce the labour intensity of workman.
The technical solution used in the present invention: casting sand and the automatic separating and reclaiming device of shot, frame is arranged on ground, it is characterized in that: uniformly in described frame be provided with spring, screen frame is packed on spring, and screen frame is fixed with screen cloth, is connected to hopper under screen frame, hopper is connected by flexible pipe with split tunnel, hopper both sides are separately installed with vibrating motor, and split tunnel side expanding channels is on molding sand elevator passage, and split tunnel opposite side expanding channels is on shot elevator passage; Described split tunnel and molding sand elevator expanding channels mouth, split tunnel and shot elevator expanding channels mouth arrange molding sand bin gate, shot bin gate respectively; Electromagnet is provided with inside described split tunnel.
The spring of uniform setting in described frame is more than 3 or 3.
Beneficial effect of the present invention is:
1, the present invention is owing to adopting driven by motor screen frame and screen mechanical vibrating shakeout mode, eliminates manual operation, improves production efficiency, reduces the labour intensity of workman.
2, the separable molding sand of the present invention's employing and the mode of shot, by arranging electromagnet in the split tunnel of screen frame hopper, split tunnel is communicated with respectively molding sand elevator and and shot elevator two passages, and by arranging bin gate respectively at two passages, effectively realize being separated of molding sand and shot, and recycling, for enterprise reduces production cost, improve economic benefit.
Accompanying drawing explanation
Fig. 1 is a kind of casting sand of the present invention and the automatic separating and reclaiming device structural representation of shot.
Fig. 2 is a kind of casting sand of the present invention and shot automatic separating and reclaiming device structure left view.
Screen frame 1, spring 2, frame 3, hopper 4, vibrating motor 5, flexible pipe 6, split tunnel 7, electromagnet 8, molding sand elevator 9, shot elevator 10, ground 11, molding sand bin gate 12, shot bin gate 13, screen cloth 14.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As Fig. 1, shown in 2, a kind of casting sand and the automatic separating and reclaiming device of shot, frame 3 is placed on ground 11, the spring 2 of uniform setting in frame 3 has 3 at least, or more than 3, in frame 3, each 6 of spring 2 is settled in both sides, screen frame 1 is packed on the spring 2 of frame 3, screen frame 1 is fixed with screen cloth 14, screen frame is connected to hopper 43 times, hopper 4 both sides install a vibrating motor 5 respectively, hopper 4 is connected by flexible pipe 6 with split tunnel 7, split tunnel 7 side expanding channels is on molding sand elevator 9 passage, split tunnel 7 opposite side expanding channels is on shot elevator 10 passage, split tunnel 7 and molding sand elevator 9 expanding channels mouth are mounted with molding sand bin gate 13, split tunnel 7 and shot elevator 10 expanding channels mouth are mounted with shot bin gate 13, electromagnet 8 is provided with inside split tunnel 7.
In casting technique, cooled foundry goods is placed on the screen frame 1 of device, switch on power, vibrating motor 5 vibrates, whole automatic separating and reclaiming device is started working, under the effect of vibration of vibrating motor 5, molding sand and shot are shaken off from foundry goods, drop into hopper 4, enter into split tunnel 7 through hopper 4 from the screen cloth 14 of screen frame 1.Now, the shot elevator 10 passage shot bin gate 13 of split tunnel 7 side is closed, the molding sand elevator 9 passage molding sand bin gate 12 of split tunnel 7 opposite side is opened, and molding sand directly enters molding sand elevator 9 from the passage of split tunnel opposite side, and shot is all adsorbed on electromagnet 8.After when molding sand, all shot has all been shaken off, close vibrating motor 5 and electromagnet 8, and open the shot elevator 10 shot bin gate 13 that split tunnel is equipped with electromagnet side, shot then all falls into elevator 10, and whole separation and recovery process completes.
