TECHNICAL FIELD
[0001] The present application belongs to the technical field of fuel filter housing production, more particularly, it is a kind of processing equipment for fuel filter housing production. BACKGROUND
[0002] Casting is a metal forming object obtained by various casting methods, that is, pouring, injection, suction or other casting methods are used to pour the smelted liquid metal into the pre-prepared casting mold, and after cooling, the subsequent processing means such as polishing, the obtained object with certain shape, size and performance. Casting has a long history. In ancient times, people used castings for some household utensils. In modern times, castings are mainly used as machine parts blanks. Some precision castings can also be directly used as machine parts.
[0003] The prior art has the following defects in the production of fuel filter housings, In the process of casting the fuel filter housing, sand is poured into the casting mold, and then the metal solution is poured into the casting mold. However, since the traditional sand casting equipment cannot screen the sand before sand removal, the sand is directly poured into the inside of the casting mold, and the large particle sand raw materials will block the inside of the casting mold, causing the inside of the casting mold to be stuck and damaged, affecting the quality of the subsequent metal solution pouring molding.
[0004] In the prior art, when the sand is screened by the processing equipment for fuel filter housing production, a large amount of impurities is located on the upper side of the filter plate due to the long-time screening of the impurities in the sand by the screening assembly, thereby gradually reducing the filtering efficiency of the filter plate. The impurities on the filter plate need to be cleaned in time. However, when cleaning the impurities on the filter plate, the dust removal effect on the sand is usually stopped, thereby affecting the efficiency of screening the sand.
[0005] In the prior art, the current screening assembly screens the sand. In order to maintain the screening effect of the sand, two screening assemblies are usually arranged symmetrically, and the two screening assemblies are used to screen the sand alternately. However, the two screening assemblies screen the sand alternately, so that only one screening assembly works at a time, thereby affecting the efficiency of screening the sand. SUMMARY

[0040] The specific use method of the present application, In the production of the fuel filter shell, at this time, the screening assembly is located above the casting box 14, the control system controls the two pairs of bidirectional telescopic rods 22 to contract, and the two pairs of bidirectional telescopic rods 22 are driven to move close to each other. Each pair of bidirectional telescopic rods 22 moves close to each other, drives the casting box 14 to move upwards and the box body 17 to move downwards to contact. The workers pour the sand into the hopper 18, the sand falls into the inside of the box body 17 through the hopper 18, and the inverted V-shaped guide plate 55 is used for inclined guiding the sand to two sides, so that the sand enters the first screening cavity 28 and the second screening cavity 29 through the two first through holes 35 and the second through holes 36 respectively to perform the screening action.
[0041] The control system controls the two second stepping motors 63 to start, and the two second stepping motors 63 drive the two cylinders 61 to rotate, and the two cylinders 61 rotate to cooperate with the two arc-shaped magnetic blocks 62 to fix the iron filings in the sand to be adsorbed on the outer walls of the two cylinders 61. The two cylinders 61 rotate to drive the iron filings to move upwards to the two guide plates 64 respectively, and the two scrapers 65 are used to scrape off the iron filings adsorbed on the outer walls of the two cylinders 61, so that the iron filings fall to the upper sides of the two guide plates 64 respectively. The two guide plates 64 are used to guide the iron filings to be inclined downwards, so that the iron filings in the first screening cavity 28 and the second screening cavity 29 move to the collecting cavity 30 through the two third through holes 37, and the iron filings in the collecting cavity 30 fall to the second collecting box 67 through the discharge port 38.
[0042] The sand in the first screening cavity 28 and the second screening cavity 29 falls to the upper sides of the two filter plates 33 respectively, the two inclined filter plates 33 are used to filter the sand, and the filtered sand falls to the flow guide groove 40, the flow guide groove 40 is used to concentrate and guide the sand, so that the sand falls to the first collecting box 66 through the discharge pipe 41, and the sand in the first collecting box 66 falls to the casting box 14 through the flap valve 68, so that the sand screening treatment effect is realized.
[0043] The impurities in the sand are retained on the upper sides of the filter plates 33, the filter plates 33 are used to guide the impurities in the sand to be inclined downwards, so that the impurities move downwards through the third through hole 37 to move to the collecting cavity 30, and the impurities in the collecting cavity 30 are guided and concentrated by the two second guide blocks 50 to fall to the second collecting box 67 through the discharge port 38. The two pressure detectors at the upper ends of the two top rods 34 are used to monitor the gravity of the two filter plates 33 in the first screening cavity 28 and the second screening cavity 29 respectively.
[0044] When the pressure detector in the first screening cavity 28 monitors that the gravity of the filter plate 33 is too large, it indicates that too many impurities are retained on the filter plate 33, which reduces the filtering effect of the filter plate 33, so that the amount of sand entering needs to be reduced and the impurities on the upper side of the filter plate 33 need to be treated.
[0045] At this time, the control system controls the electric telescopic rod 51 to extend, and the electric telescopic rod 51 extends to push the movable box 26 to move towards the second screening cavity 29. The movable box 26 moves to drive the two second through holes 36 to move, so that the misalignment degree between the second through hole 36 above the first screening cavity 28 and the first through hole 35 is increased, and the amount of sand entering the first screening cavity 28 through the first through hole 35 and the second through hole 36 is reduced. And the coincidence degree between the second through hole 36 above the second screening cavity 29 and the first through hole 35 is increased, and the amount of sand entering the second screening cavity 29 through the first through hole 35 and the second through hole 36 is increased, so that the filter plate 33 in the first screening cavity 28 can be treated in time and the efficiency of sand screening treatment can be maintained.
[0046] Meanwhile, the moving box 26 moves towards the second screening cavity 29 direction, which drives the two push blocks 59 to move, and the two push blocks 59 move to push the lower end of the movable plate 56, so that the upper end of the movable plate 56 swings away from the second screening cavity 29 direction. The upper end of the movable plate 56 swings to drive the rubber rod 58 to move away from the second screening cavity 29 direction, and the rubber rod 58 moves away from the second screening cavity 29 direction to drive the V-shaped guide plate 55 to move a small distance away from the second screening cavity 29 direction, so that the middle part of the V-shaped guide plate 55 is close to the first screening cavity 28 direction. At this time, the sand through the funnel 18 falls, most of which moves to the second screening cavity 29 direction, and a small part moves to the first screening cavity 28 direction, preventing a large amount of sand from being retained on the upper side of the shell 25, and maintaining the efficiency of screening a large amount of sand.
[0047] The movable frame 31 in the first screening cavity 28 moves close to the second screening cavity 29 direction, and is pulled by the connecting plate 32, so that the movable frame 31 moves downward in the first screening cavity 28. The movable frame 31 moves downward to drive the filter plate 33 to move downward, and the filter plate 33 moves downward to increase the impurity flux of the third opening 37, so that a large amount of impurities can pass through the third opening 37 into the collection cavity 30, which is beneficial to quickly reduce the impurities on the upper side of the filter plate 33. The movable frame 31 moves horizontally to drive the top rod 34 to move horizontally, and the lower end of the top rod 34 is guided by the upper inclined surface of the guide block 43, so that the top rod 34 moves upward. The top rod 34 moves upward to push the inclined lower end of the filter plate 33 to swing upward, thereby reducing the angle of inclination of the filter plate 33, reducing the efficiency of the filter plate 33 in screening sand, and reducing the amount of sand entering the collection cavity 30. And the movable frame 31 moves horizontally to drive the top rod 34 to move horizontally, and the top rod 34 moves horizontally to cooperate with the guide block 43 to be fixed, so as to guide the lower end of the top rod 34 by the plurality of protrusions 45, so as to make the top rod 34 move up and down in a small amplitude under the guidance of the plurality of protrusions 45 and under the gravity of the filter plate 33. The small amplitude up and down movement of the top rod 34 makes the filter plate 33 shake in a small amplitude, and the filter plate 33 is inclined and shakes in a small amplitude, which can make the sand and impurities shake and disperse uniformly, and promote the impurities to move downward along the inclined surface of the filter plate 33, and accelerate the efficiency of the impurities to separate from the filter plate 33.
[0048] The movable frame 31 in the second screening cavity 29 moves away from the first screening cavity 28, is pushed by the rotation of the connecting plate 32, and moves upward in the second screening cavity 29. The upward movement of the movable frame 31 drives the filter plate 33 to move upward, and the upward movement of the filter plate 33 reduces the impurity flux of the third through port 37, so that a small amount of impurities can pass through the third through port 37 into the collection cavity 30, reducing the amount of sand and impurities passing through the third through port 37 into the collection cavity 30. The horizontal movement of the movable frame 31 drives the top rod 34 to move horizontally, and the lower end of the top rod 34 is guided by the upper inclined surface of the guide block 43 and the gravity of the filter plate 33, so that the lower end of the top rod 34 is in sliding contact with the upper inclined surface of the guide block 43, and the top rod 34 moves downward under the action of the gravity of the filter plate 33. The downward movement of the top rod 34 swings the inclined lower end of the filter plate 33 downward, thereby increasing the angle of inclination of the filter plate 33 and improving the efficiency of the filter plate 33 in screening the sand, so that a large amount of sand can be screened. The horizontal movement of the movable frame 31 drives the top rod 34 to move horizontally, and the top rod 34 is fixed with the guide block 43, so that the lower end of the top rod 34 is guided by the protrusions 45, so that the top rod 34 can move up and down in a small amplitude under the guidance of the protrusions 45 and the gravity of the filter plate 33. The small-amplitude up-and-down movement of the top rod 34 causes the filter plate 33 to vibrate slightly, and the slight vibration of the inclined filter plate 33 can make a large amount of sand vibrate and disperse uniformly, thereby improving the screening efficiency of a large amount of sand and maintaining the high-efficiency screening effect of the sand, which is beneficial to improving the efficiency of the fuel filter housing casting.
[0049] Similarly, according to the pressure detectors on the upper ends of the two top rods 34, the amount of impurities retained on the two filter plates 33 in the first screening cavity 28 and the second screening cavity 29 can be transmitted to the control system in a timely manner, and the control system can control the extension and retraction of the electric telescopic rod 51 to adjust the amount of sand entering the first screening cavity 28 and the second screening cavity 29, the degree of inclination of the two filter plates 33, and the amount of impurities discharged by the two third through ports 37, so as to maintain high-efficiency sand screening and timely handle the impurities retained on the upper side of the filter plate 33.
[0050] The processed sand in the two first collecting boxes 66 falls into the casting box 14 through the two flap valves 68. When the casting box 14 is filled with the sand, the two pairs of double extension rods 22 are extended to push the two pairs of movable blocks 21 away from each other. The two movable blocks 21 moving away from each other drives the casting box 14 to move downward and the box body 17 to move upward. The control system controls the two drive motors 20 to start, and the two drive motors 20 drive the two rotating shafts 12 to rotate, and the two rotating shafts 12 drive the two circular plates 13 to rotate, and the two circular plates 13 drive the casting box 14 and the box body 17 to be horizontally side by side. At this time, the staff compacts the sand around the wooden mold to make the sand core of the internal cavity. The casting cover 15 is sealed on the upper side of the casting box 14, and is fixed by the positioning pin or bolt to ensure the sealing of the mold cavity. The molten metal is quickly poured into the mold cavity through the sprue 16 to fill the mold cavity with the molten metal. The metal gradually cools in the mold cavity, and thus the fuel filter shell is formed.
[0051] The processing equipment for producing the fuel filter shell of the present application is provided with the ejector rod 34 and the guide block 43. When the shell body 25 moves towards the second screening cavity 29, the movable frame 31 in the first screening cavity 28 moves horizontally to drive the ejector rod 34 to move horizontally. The lower end of the ejector rod 34 is guided by the upper inclined surface of the guide block 43, so that the ejector rod 34 moves upward. The upward movement of the ejector rod 34 pushes the inclined lower end of the filter plate 33 to swing upward, thereby reducing the inclination angle of the filter plate 33 and reducing the efficiency of the filter plate 33 in screening the sand and the amount of sand entering the collecting cavity 30. The movable frame 31 in the second screening cavity 29 moves horizontally to drive the ejector rod 34 to move horizontally. The lower end of the ejector rod 34 is guided by the upper inclined surface of the guide block 43 and the gravity of the filter plate 33, so that the lower end of the ejector rod 34 slides with the upper inclined surface of the guide block 43, thereby moving downward under the action of the gravity of the filter plate 33. The downward movement of the ejector rod 34 makes the inclined lower end of the filter plate 33 swing downward, thereby increasing the inclination angle of the filter plate 33 and improving the efficiency of the filter plate 33 in screening the sand, so as to screen a large amount of sand.
[0052] The application discloses a processing equipment for fuel filter shell production, when the shell 25 moves towards the second screening cavity 29, the movable frame 31 in the first screening cavity 28 moves horizontally to drive the top rod 34 to move horizontally, the top rod 34 moves horizontally to cooperate with the guide block 43 to be fixed, so that the lower end of the top rod 34 is guided by the protrusions 45, under the guidance of the protrusions 45 and the gravity of the filter plate 33, the top rod 34 can move up and down in a small range. The small amplitude up and down movement of the top rod 34 makes the filter plate 33 shake in a small range, the filter plate 33 is inclined and shakes in a small range, the sand and impurities can be shaken and dispersed uniformly, and the impurities are inclined to move downwards along the inclined surface of the filter plate 33, so that the efficiency of the impurities separated from the filter plate 33 is improved. The movable frame 31 in the second screening cavity 29 moves horizontally to drive the top rod 34 to move horizontally, under the guidance of the protrusions 45 and the gravity of the filter plate 33, the top rod 34 can move up and down in a small range. The small amplitude up and down movement of the top rod 34 makes the filter plate 33 shake in a small range, the filter plate 33 is inclined and shakes in a small range, a large amount of sand can be shaken and dispersed uniformly, so that the screening efficiency of the large amount of sand is improved, the effect of efficiently screening the sand is maintained, and the efficiency of the fuel filter shell casting is improved.
