Description
Technical field
The present invention relates to a kind of metal casting machine, be specifically related to method and sanding device that a kind of core making machine quantitatively adds sand.
Background technology
Sand casting is the casting method becoming casting mold with molding sand consolidation, is widely used in the production of cast iron and steel-casting.Wherein, the manufacture of core is one important operation in sand casting.Core is generally prepare realization by core making machine by core box.Core making machine generally includes frame, sanding device, She Sha mechanism, air blowing shield and core box hoisting mechanism, and wherein, sanding device generally comprises sand storage bin and being arranged on and penetrates and add sand butterfly valve above chamber, and molding sand enters add sand cylinder through adding sand butterfly valve.
Existingly fixedly penetrating head dummy core making machine, by controlling to add opening or closing of sand butterfly valve, realizing adding sand, by the control adding the sand time is limited add sand amount number, be difficult to accurate control.Add sand overlong time, sand amount is too much, adds sand butterfly valve seal device and easily damages, and also produces the waste of a large amount of energy consumption; Add the sand time too short, adding sand amount not, may affect the process of coremaking.In addition, if it is too much to add sand, penetrates in chamber and be full of molding sand, certainly will will strengthen shooting pressure, be difficult to the making realizing some more complicated cores, also easily cause core making machine core box to reduce service life.
Chinese invention patent application CN102166617A discloses a kind of sand proportioning device, comprise a support, described support is provided with one and adds sandpipe, the described below adding sandpipe is provided with an electronic scale, described electronic scale is connected with a reversing device, described reversing device can drive described electronic scale to reverse, and is provided with quantitative sand hopper below described electronic scale.This sand proportioning device can realize the automatic weighing to the molding sand poured in quantitative sand hopper, to control to add sand amount.But this device, needs to arrange reversing device as the transition apparatus adding sand by electronic scale, meanwhile, needing, twice are set and add sand butterfly valve, complex structure; Reversing device is easily polluted by molding sand and operates malfunctioning; Due to the setting of electronic scale and reversing device, add sand passage and expose, easily cause molding sand to release or contaminated; Further, because the molding sand penetrated in sand chamber not necessarily can exhaust, add sand molding sand may be caused after repeatedly adding sand to overflow by weighing the method adding sand.
Therefore, need to improve the sand method and apparatus that quantitatively adds of core making machine, the science of realization adds sand.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of core machine ration and adds sand method, quantitatively adds sand with what realize core making machine efficiently and accurately.Another goal of the invention of the present invention is to provide a kind of device realizing this and quantitatively add sand method.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of core machine ration adds sand method, and adding sand butterfly valve and penetrating between sand chamber below sand storage bin arranges Jia Sha travel mechanism, arranges sand position height sensor; When adding sand, mixing system is to back-up sand in sand storage bin, and Jia Sha travel mechanism moves to and adds sand position, is communicated with and adds the outlet of sand butterfly valve and penetrate sand chamber; Sand position height sensor detects the sand position height penetrated in sand chamber, judges whether to need to add sand, as needs add sand, then open and add sand butterfly valve, meanwhile, sand position height sensor detects the sand position penetrated in sand chamber and whether arrives setting height, when arriving setting height, close and add sand butterfly valve; Shift out Jia Sha travel mechanism, complete and add sand.
In technique scheme, by arranging Jia Sha travel mechanism, adding the outlet of sand butterfly valve and penetrating sand chamber adding in sand flow journey to be communicated with, avoiding molding sand to leak, because Jia Sha travel mechanism is moveable, can not affect and penetrate normally carrying out of sand flow journey and air blowing flow process.The movement of Jia Sha travel mechanism can be realized by such as cylinder or hydraulic cylinder.Obtain sand position by sand position height sensor highly to control to add sand amount, easy to operate, structure is simple, can effectively control sand amount.
Further technical scheme, arranges sand position flood sensor, when sand position flood sensor detects that sand position is overflowed, closes and adds sand butterfly valve.
A kind of core machine ration sanding device, comprise sand storage bin, be arranged on adding sand butterfly valve, be positioned to add and penetrate sand chamber and controlling organization below sand butterfly valve below sand storage bin, described adding below sand butterfly valve, is provided with Jia Sha travel mechanism, described Jia Sha travel mechanism comprise with penetrate that sand top of chamber passage coordinates add sand cover and drive unit, add sand cover and there are two working positions, adding sand working position, adding sand cover and adding sand butterfly valve and penetrating between sand chamber, and connection adds the outlet of sand butterfly valve and penetrates sand top of chamber passage; Be provided with sand position height sensor, the output of sand position height sensor is electrically connected with the input of controlling organization, and the output of controlling organization is electrically connected with the controller adding sand butterfly valve.
In technique scheme, the drive unit in Jia Sha travel mechanism, can adopt as cylinder or hydraulic cylinder realize, as required, arrange guide post and lead to the movement adding sand cover, makes to add sand cover and enters or exit and add sand working position.
Further technical scheme, is provided with sand position flood sensor, and the output of described sand position flood sensor is electrically connected with the input of controlling organization.
In technique scheme, described sand position height sensor is be arranged on the photoelectric sensor added below sand butterfly valve.
Described sand position flood sensor is be arranged on the photoelectric sensor added below sand butterfly valve.
Preferred technical scheme, described photoelectric sensor is laser ranging type sensor, measurement category 150 ~ 2000mm, and the way of output is 0 ~ 10v analog output.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. the present invention is by arranging sand position height sensor and Jia Sha travel mechanism, realizes quantitatively adding sand, solves the ratio problems of sand amount and air-flow in shooting case of core maker sand chamber, is conducive to improving core box service life, is suitable for making complicated core; Meanwhile, method of the present invention is simple, does not need to do large variation to sanding device structure, is easy to realize.
2. adopt Jia Sha travel mechanism to be communicated with add the outlet of sand butterfly valve and penetrate sand chamber, make to add sand passage and do not expose, avoid passage and expose the adverse effect caused.
