Abstract
The computer control method of sand-covering moulding machine for founding adopts the following control steps: starting system work and putting initialization data of required given sand-shooting time and pipeline gas pressure, then testing pipeline gas pressure value and defining that said value is reached to the required sand-shooting pressure or not, then testing that the sand-shooting time is reached or not. By adopting computer to control sand-covering moulding machine it can continuously make sand-covering moulds which are uniform and identical, not only can reduce labour intensity, but also can raise working efficiency and reduce production cost.
Description
The present invention relates to a kind of sand molding machine that covers and carry out computer-controlled method casting usefulness.
At present, the sand molding machine that covers of casting usefulness is mainly finished by manually-operated swage is penetrated sand, it is penetrated the sand amount and penetrates the sand time only by rule of thumb or feel to finish.So concerning same product, the sand mold of making is difficult to guarantee identical, substandard products occur through regular meeting, directly influence is by the quality of foundry goods.In addition,, not only increase labour intensity, but also increase by the cost of foundry goods because manually-operated efficient is low.
Task of the present invention provides a kind ofly carries out computer-controlled method to covering the sand molding machine, and it has used a kind of computer program correlation sand process to carry out continuously control in real time.
For finishing above-mentioned task, the present invention includes one is used to store and supplies the sand body of penetrating that the sand hopper that covers sand and engages with the inlet of this sand hopper below, and be arranged on penetrate sand body below be used to carry the sand molding machine that covers that the carrier mechanism of swage forms and carry out computer-controlled method, it adopts following control step:
Start-up system work is also inserted required given penetrating the sand time, initialization datas such as pipeline gas pressure;
Whether the gas pressure of test in the pipeline reaches should be penetrated sand pressure, as reaches and penetrate sand pressure, opens perforation and closes air bleeding valve, makes perforation penetrate sand;
Measurement is penetrated the sand time and whether is reached prior set-point, as reaches and close perforation and open air bleeding valve, withdraws from control program, continues to penetrate sand as not reaching.
Because the present invention adopts the computer program control sand molding machine that covers of the prior art, it can make make continuously cover sand mo(u)ld type homogeneous phase with, not only can reduce labour intensity, but also can improve work efficiency, reduce production cost.
Below in conjunction with accompanying drawing the present invention is elaborated.
Accompanying drawing 1 is to cover the schematic diagram directly perceived that sand causes machine;
Accompanying drawing 2 is the computer program flow charts among the present invention.
Referring to Fig. 1, device shown in it be casting usefulness cover the sand molding machine, by one be used to store and supply that the sand hopper 1 that covers sand and one engages with the inlet 11 of this sand hopper below penetrate sand body 2, and be arranged on the carrier mechanism 3 that is used to carry swage of penetrating sand body 2 belows and constitute.Sand hopper 1 below is provided with a control valve 4, when this control valve is extracted out when inlet 11 is opened, sand hopper 1 can be in the body 2 that shoots material feed.The described lower surface of penetrating sand body 2 is provided with several rows of perforation 21, and what the arrangement of this perforation should be with by the foundry goods external form is peripheral corresponding, and the folding condition of perforation 21 is controlled by pressure sensor.Penetrating sand body 2 penetrates the sand process and is: when carrier mechanism 3 is transported to swage when contacting with the plane at perforation 21 places, rise gradually with pressure in penetrating the pneumatic circuit 5 that sand body 2 communicates this moment, when reaching certain numerical value, pressure sensor is connected, pin air bleeding valve 22, get through perforation 21, the sand of penetrating in the sand body 2 that covers is jetted on the swage of its bottom by perforation 21; Wait to penetrate sand to certain hour, promptly finish cover the type task after, open air bleeding valve 22 this moment, seals perforation 21, finishes and once penetrate sand action.
As can be seen,, place again in the computer program, can realize controlling automatically covering the sand molding machine as long as select in advance to covering in the sand molding machine sand time of penetrating of the gas pressure value in the gas piping 5 and perforation 21.
Referring to Fig. 2, Fig. 2 is a flow chart of penetrating the sand control system.Behind program start, at first carry out initialization, insert in the required pneumatic circuit gas pressure and penetrate initial value such as sand time; Whether the air pressure in the test gas pipeline reaches the numerical value that sets then, as reaches and penetrate sand pressure, then opens perforation and closes air bleeding valve, makes perforation penetrate sand; Judge again whether penetrate the sand time reaches prior set-point, as reach, close perforation and open air bleeding valve, withdraw from control program; Continue to penetrate sand as not reaching.
After this program was finished, the top of getting back to program again continued to restart test, carried out again and again.
Claims (1)
1, a kind ofly is used to store and supplies the sand body of penetrating that the sand hopper that covers sand and engages with the inlet of this sand hopper below including one, and be arranged on penetrate sand body below be used to carry the computer-controlled method of carrying out of covering the sand molding machine that the carrier mechanism of swage is formed, it is characterized in that adopting following control step:
Start-up system work is also inserted required given penetrating the sand time, initialization datas such as pipeline gas pressure;
Whether gas pressure reaches and should penetrate sand pressure in the test pipeline, as reaches and should penetrate sand pressure, opens perforation and closes air bleeding valve, makes perforation penetrate sand;
Test is penetrated the sand time and whether is reached prior set-point, as reaches and close perforation and open air bleeding valve, withdraws from control program; Can continue to penetrate sand as not reaching.
