Description

Technical Field

[0001] The present invention relates to the technical field of pump housing casting, and particularly to an intelligent casting island for the production of mud pump housings. Background Art

[0002] As a core equipment in fields such as oil drilling, mine exploitation, and river dredging, the housing of a mud pump needs to withstand the severe scouring, abrasive wear, and chemical corrosion of high-pressure mud for a long time, and has extremely high requirements for the corrosion resistance, impact resistance, and structural reliability of the material. At present, high-chromium cast iron (such as Cr26, Cr28 series) has become the mainstream casting material for mud pump housings due to its excellent wear resistance and corrosion resistance. However, the high-carbon and high-chromium components of high-chromium cast iron result in a high melting temperature (1500 - 1600 °C), poor fluidity, and large shrinkage rate. During the casting process, defects such as shrinkage cavities, gas holes, and cracks are extremely likely to occur due to insufficient sand mold compaction or uneven cooling. In addition, the mud pump housing usually has a complex flow channel structure, an asymmetric flange interface, and a cross-section with sudden changes in thickness. It is difficult for traditional sand casting to accurately reproduce its geometric features, while the lost foam casting technology (EPC) provides an effective way to solve the forming of complex structures through the method of burying a foam model in sand.

[0003] In the lost foam casting process, the uniformity of the sand mold compaction directly determines the quality of the casting. In the prior art, in the sand vibration link, on the one hand, the vibration mechanism mostly uses single vertical vibration or mechanical compaction, and the vibration force is concentrated in a local area, resulting in a significant gradient of the sand mold compaction. The sand grain gaps in the thin-wall area are large, and the molten metal is likely to penetrate into the sand mold during pouring to form mechanical sand adhesion. On the other hand, in the rigid fixed mode of the sand box, the vibration energy transfer efficiency is low, the resonance effect of the sand box is weak, the gaps between some sands are large, and the gas discharge path is blocked, resulting in an increase in the porosity defect rate of the casting.

[0034] The driving assembly 8 includes a mounting frame 802 fixedly connected to the bottom surface of the fixed plate 7, a fixed disk 801 is fixedly installed inside the mounting frame 802, a lifting column 803 that can slide up and down is arranged on the outer wall of the fixed disk 801, and a first connecting seat 804 is fixedly installed at the upper end of the lifting column 803;

[0035] The vibrating assembly 9 includes a first lever 901 rotatably connected to the upper outer wall of the first connecting seat 804. A first support rod 903 is fixedly installed on the upper surface of the fixing plate 7 below the first lever 901, and the upper end of the first support rod 903 is rotatably connected to the middle position of the first lever 901. One end of the first lever 901 away from the first connecting seat 804 is rotatably connected to a connecting rod 902. A fixing block 904 is fixedly installed on the outer wall of the fixing plate 7 below the connecting rod 902. A first vibrating rod 905 is slidably installed at the middle position of the fixing block 904. The end of the connecting rod 902 away from the first lever 901 is rotatably connected to the upper end of the first vibrating rod 905. The lower end of the first vibrating rod 905 is connected to a second vibrating rod 907, and a vibrating plate 908 is fixedly installed on the bottom surface of the second vibrating rod 907;

[0036] The vibration assembly 12 includes a first swing rod 1201 rotatably installed at the lower end of one side of the extension frame 1101, and also includes a second swing rod 1206 rotatably installed at the middle position of the other side of the extension frame 1101. The first swing rod 1201 and the second swing rod 1206 are respectively distributed on both sides of the lifting column 803, and arc-shaped rods 1207 are fixedly installed at the ends of the first swing rod 1201 and the second swing rod 1206 away from the lifting column 803;

[0037] When the transporter 2 moves to the sand adding station, part of the molding sand is added into the interior of the sand box 5 through the existing sand adding device at the sand adding station. At this time, by adjusting the first electric telescopic rod 3, the height of the fixed frame 10 provided at the upper end of the first electric telescopic rod 3 can be reduced. By driving the lifting column 803 included in the driving assembly 8 to move up and down, the first connecting seat 804 fixedly installed at the upper end of the lifting column 803 moves upward. The first connecting seat 804 is connected to the end of the first lever 901. When the end of the first lever 901 connected to the first connecting seat 804 is lifted upward, under the action of the lever principle, the first lever 901 rotates with the connection point with the first support rod 903 as the fulcrum. Then the other end of the first lever 901 moves downward. Under the action of the connecting rod 902, the first vibrating rod 905 is pressed downward. Further, through the transmission of force by the first vibrating rod 905 and the second vibrating rod 907, etc., the vibrating plate 908 is pushed downward. The number of vibrating plates 908 is four. The four vibrating plates 908 vibrate the corresponding areas inside the box body 501 respectively. And during the process of the vibrating plate 908 vibrating the molding sand inside the box body 501, the second connecting seat 1203 fixedly installed at the lower end of the lifting column 803 moves up and down synchronously with the lifting column 803. One side of the second connecting seat 1203 is slidably connected to the first swing rod 1201. A circular shaft is fixedly installed at the connection end of the second connecting seat 1203 and the first swing rod 1201. A chute matching the circular shaft is provided at the end of the first swing rod 1201. The sliding connection between the second connecting seat 1203 and the first swing rod 1201 is realized by the circular shaft sliding inside the chute. Then when the second connecting seat 1203 moves upward, the connection end of the first swing rod 1201 and the second connecting seat 1203 is lifted upward. Similarly, under the action of the lever principle, the end of the arc-shaped rod 1207 rotates downward with the connection point of the first swing rod 1201 and the extension frame 1101 as the axis, and can knock on the outer wall of the upper end of the box body 501. When the second connecting seat 1203 moves downward, the end of the second swing rod 1206 can be indirectly driven to be lifted. The arc-shaped rod 1207 provided at the end of the second swing rod 1206 swings downward to drive the rubber hammer 1202 provided at its end to knock on the extension block 502. The two arc-shaped rods 1207 drive the rubber hammers 1202 to alternately knock on the upper end of the sand box 5, and the gaps between the molding sands inside the sand box 5 can be reduced by vibration, which is more conducive to vibrating and compacting the molding sand inside the sand box 5.

[0038] As a technical optimization solution of the present invention, a second connecting seat 1203 is fixedly installed at the lower end of the lifting column 803. The end of the first swing rod 1201 close to the lifting column 803 is slidably connected to one side of the second connecting seat 1203. The end of the second swing rod 1206 far from the arc rod 1207 is slidably connected to a second lever 1205. A connecting piece is rotatably connected to one end of the second lever 1205 far from the second swing rod 1206, and the other end of the connecting piece is rotatably connected to the other side of the second connecting seat 1203. A second support rod 1204 is fixedly installed on the inner wall of the bottom surface of the extension frame 1101 below the second lever 1205, and the upper end of the second support rod 1204 is rotatably connected to the outer wall of the second lever 1205;

[0039] When the second connecting seat 1203 moves downward, one end of the second lever 1205 is driven downward under the driving action of the connecting piece. Under the action of the lever principle, with the upper end of the second support rod 1204 as the fulcrum, the other end of the second lever 1205 is lifted upward. The other end of the second lever 1205 is slidably connected to the second swing rod 1206. When the end of the second lever 1205 is lifted upward, it can also drive the end of the second swing rod 1206 upward, and further make the arc rod 1207 fixedly installed at the other end of the second swing rod 1206 swing downward with the connection point between the second swing rod 1206 and the extension frame 1101 as the axis. When the second connecting seat 1203 moves upward, it can swing the arc rod 1207 fixedly installed at the end of the first swing rod 1201 downward with the connection point between the first swing rod 1201 and the extension frame 1101 as the axis by raising the end of the first swing rod 1201.

[0040] As a technical optimization solution of the present invention, a movable frame 806 is fixedly installed at the middle position of the lifting column 803. A rotating block 807 is rotatably installed at the center position of the fixed disk 801. A guide post 808 is rotatably installed at the end of the rotating block 807, and the guide post 808 is located inside the movable frame 806 to drive the movable frame 806 to move up and down;

[0041] A second servo motor is fixedly installed at the center position of the outer wall of one side of the fixed disk 801. The rotating block 807 is driven by the second servo motor to rotate around the center of the fixed disk 801. The guide post 808 is arranged at the end of the rotating block 807. When the rotating block 807 rotates around the center of the fixed disk 801, the guide post 808 arranged at the end of the rotating block 807 makes a circular motion. When the guide post 808 rotates, the guide post 808 can only slide inside the movable frame 806, so as to drive the movable frame 806 to move up and down, and further drive the lifting column 803 to move up and down.

[0042] As a technical optimization solution of the present invention, a cross plate 1102 is fixedly installed on the bottom surface of the extension frame 1101. Four ends of the cross plate 1102 are fixedly installed with second electric telescopic rods 1103, and elastic pads are fixedly installed at the ends of the four second electric telescopic rods 1103.

[0043] After the molding sand at the bottom of the box body 501 is leveled, the user places the lost foam model of the mud pump housing into the inside of the sand box 5. The output ends of the four groups of second electric telescopic rods 1103 arranged on the cross plate 1102 can be extended to perform multi-point fixation on the upper end of the foam model of the mud pump housing. The elastic pads arranged at the ends of the second electric telescopic rods 1103 can prevent the outer wall of the foam model from being damaged when the second electric telescopic rods 1103 press the foam model. Under the combined action of multiple second electric telescopic rods 1103, the foam model of the mud pump housing can be stably placed on the leveled molding sand.

[0044] As a technical optimization solution of the present invention, the sand box 5 specifically includes a box body 501, and an extension block 502 is fixedly installed at the upper end of one side of the box body 501; the extension block 502 is fixedly connected to the box body 501. When the extension block 502 is struck, it can drive the box body 501 to vibrate synchronously.

[0045] As a technical optimization solution of the present invention, the sliding assembly 6 includes a sliding bottom plate 601 slidably connected to the upper surface of the mounting plate 4. A plurality of equally spaced tooth grooves 602 are opened on both sides of the sliding bottom plate 601. Driving gears 604 meshing with the plurality of tooth grooves 602 are rotatably installed on the upper surface of the mounting plate 4 on both sides of the sliding bottom plate 601. A plurality of uniformly distributed first springs 603 are fixedly installed on the upper surface of the sliding bottom plate 601, and the upper ends of the plurality of first springs 603 are fixedly connected to the bottom surface of the box body 501; under the action of the sliding assembly 6 arranged on the upper surface of the mounting plate 4, the sand box 5 can be moved from one end of the upper surface of the mounting plate 4 below the fixed plate 7 to the other end. During this process, first servo motors are fixedly installed at the corresponding positions on both sides of the bottom surface of the mounting plate 4 corresponding to the driving gears 604. The output ends of the first servo motors are fixedly connected to the middle positions of the driving gears 604. When the first servo motors drive the driving gears 604 to rotate, the driving gears 604 drive the sliding bottom plate 601 to slide on the upper surface of the mounting plate 4 under the meshing transmission action with both sides of the sliding bottom plate 601. The box body 501 and the sliding bottom plate 601 are connected by a plurality of first springs 603. When the two arc-shaped rods 1207 drive the rubber hammers 1202 to alternately strike the box body 501 and the extension block 502, the box body 501 of the box body 501 generates slight vibration.

[0046] As a technical optimization solution of the present invention, rubber hammers 1202 are fixedly installed at the ends of two arc-shaped rods 1207, and the two arc-shaped rods 1207 are respectively distributed on both sides of the sand box 5. Among them, the arc-shaped rod 1207 arranged at the end of the second swing rod 1206 is arranged on the same side as the extension block 502; during the up and down movement of the lifting column 803, the two arc-shaped rods 1207 drive the rubber hammers 1202 to alternately strike the box body 501 and the extension block 502, and the gap between the molding sands inside the box body 501 can be reduced by vibration, which is more conducive to the vibrating plate 908 vibrating and compacting the molding sands inside the box body 501.

[0047] As a technical optimization solution of the present invention, two groups of symmetrically arranged limit columns 805 are fixedly installed on the outer wall of the fixed disk 801. The lifting column 803 slides up and down between the two groups of limit columns 805, and the outer walls of both sides of the lifting column 803 are respectively in contact with the outer walls of the two groups of limit columns 805; the setting of the limit columns 805 can play a role in limiting the lifting column 803. The outer wall of the lifting column 803 is provided with strip-shaped convex ribs protruding outwards, and the outer wall of the limit column 805 is provided with grooves matching the strip-shaped convex ribs. When the lifting column 803 slides up and down between the two groups of limit columns 805, the convex ribs on the lifting column 803 slide inside the grooves opened on the limit columns 805.

[0048] As a technical optimization solution of the present invention, a second spring 906 is arranged between the first vibrating rod 905 and the second vibrating rod 907, and both ends of the second spring 906 are fixedly connected to the outer walls of the ends of the first vibrating rod 905 and the second vibrating rod 907 respectively; the setting of the second spring 906 can prevent the first vibrating rod 905 from making hard contact with the molding sand or the upper end of the box body 501 with inaccurate positioning during the downward movement.

[0049] As a technical optimization solution of the present invention, the vibrating plates 908 are distributed at the four corners of the box body 501, and chamfers are provided on the circumferential sides of the bottom surfaces of the vibrating plates 908. When there is a small error in the positioning of the box body 501 below the fixed plate 7, under the guiding action of the chamfers provided on the circumferential sides of the bottom surfaces of the vibrating plates 908, the second spring 906 is slightly deformed, ensuring that the vibrating plates 908 can contact the upper surfaces of the molding sands added inside the box body 501 and vibrating and compacting the molding sands.

[0050] When the present invention is in use, under the action of the transporter 2, the mounting plate 4 and other components arranged above the transporter 2 can be driven to move along the upper surface of the support bracket 1. A plurality of casting stations are arranged along the outer side line of the support bracket 1, such as a preparation station, a sand adding station, a pouring station, a blanking station, etc. The pouring station and the sand adding station are arranged corresponding to each other on both sides of the support bracket 1. Among them, both the transporter 2 and the support bracket 1 are prior arts, and their specific implementation manners and the achieved effects are well-known common sense and conventional technical means in the art, and will not be elaborated here. When the transporter 2 moves to the sand adding station, part of the molding sand is added into the interior of the box body 501 through the existing sand adding device at the sand adding station. At this time, by adjusting the first electric telescopic rod 3, the height of the fixing frame 10 arranged at the upper end of the first electric telescopic rod 3 can be reduced. In this device, a second servo motor is fixedly installed at the center position of the outer wall on one side of the fixed disk 801. By driving the rotating block 807 to rotate around the center of the fixed disk 801 through the second servo motor, when the guide post 808 arranged at the end of the rotating block 807 moves inside the movable frame 806, it can drive the movable frame 806 to move up and down, and then drive the lifting column 803 to move up and down. Then, during the up and down movement of the lifting column 803, a plurality of vibration components 9 can be driven to move up and down to tamp and level the part of the molding sand added into the interior of the box body 501. During the process of tamping and leveling the molding sand by the plurality of vibration components 9 moving up and down, the ends of the two arc-shaped rods 1207 arranged on both sides of the box body 501 alternately strike both sides of the box body 501. When the molding sand at the bottom of the box body 501 is leveled, the user places the lost foam pattern of the mud pump shell into the interior of the sand box 5. The output ends of the four groups of second electric telescopic rods 1103 arranged on the cross plate 1102 extend to perform multi-point fixation on the upper end of the mud pump shell foam pattern. The elastic pads arranged at the ends of the second electric telescopic rods 1103 can prevent the second electric telescopic rods 1103 from damaging the outer wall of the foam pattern during the process of pressing the foam pattern. Then, under the combined action of the plurality of second electric telescopic rods 1103, the foam pattern of the mud pump shell can be stably placed on the leveled molding sand. Then, the interior of the box body 501 can be continuously filled with molding sand through an external sand adding device. When the molding sand in the box body 501 is added to the specified amount, the height of the first electric telescopic rod 3 is adjusted to increase. Then, the second servo motor is started again. When the lifting column 803 moves upward, the first connection seat 804 fixedly installed at the upper end of the lifting column 803 moves upward. The first connection seat 804 is connected to the end of the first lever 901. When the end of the first lever 901 connected to the first connection seat 804 is lifted upward, under the action of the lever principle, the first lever 901 rotates around the connection point with the first support rod 903 as the fulcrum. Then, the other end of the first lever 901 moves downward. Under the action of the connecting rod 902, the first vibrating rod 905 is pressed downward. Then, through the transmission of force by the first vibrating rod 905, the second vibrating rod 907, etc., the vibrating plate 908 is pushed downward. The number of the vibrating plates 908 is four.Four vibrating plates 908 vibrate the corresponding areas inside the box body 501 respectively. During the process of the vibrating plates 908 vibrating the molding sand inside the box body 501, the second connecting seat 1203 fixedly installed at the lower end of the lifting column 803 moves up and down synchronously with the lifting column 803. One side of the second connecting seat 1203 is slidably connected to the first swing rod 1201. A circular shaft is fixedly installed at the connecting end of the second connecting seat 1203 and the first swing rod 1201, and a chute matching the circular shaft is provided at the end of the first swing rod 1201. The sliding connection between the second connecting seat 1203 and the first swing rod 1201 is realized by the sliding of the circular shaft inside the chute. When the second connecting seat 1203 moves upward, the connecting end of the first swing rod 1201 and the second connecting seat 1203 is lifted upward. Similarly, under the action of the lever principle, the end of the arc-shaped rod 1207 equipped with the rubber hammer 1202 rotates downward with the connection point between the first swing rod 1201 and the extension frame 1101 as the axis, and the upper outer wall of the box body 501 can be knocked by the rubber hammer 1202 arranged at the end of the arc-shaped rod 1207. When the second connecting seat 1203 moves downward, the end of the second lever 1205 connected to the second connecting seat 1203 is pressed downward, then the other end of the second lever 1205 is lifted upward. The connection mode between the second lever 1205 and the end of the second swing rod 1206 is the same as the connection mode between the second connecting seat 1203 and the first swing rod 1201. When the end of the second lever 1205 is lifted upward, the arc-shaped rod 1207 arranged at the end of the second swing rod 1206 swings downward to drive the rubber hammer 1202 arranged at its end to knock the extension block 502. Then, during the upward movement of the lifting column 803, the upper outer wall of the box body 501 can be knocked by the arc-shaped rod 1207 arranged at the end of the first swing rod 1201, and during the downward movement of the lifting column 803, the extension block 502 can be knocked by the arc-shaped rod 1207 arranged at the end of the second swing rod 1206. Then, the two arc-shaped rods 1207 drive the rubber hammers 1202 to alternately knock the box body 501 and the extension block 502, and the gap between the molding sands inside the box body 501 can be reduced by vibration, which is more conducive to the vibrating plate 908 vibrating the molding sand inside the box body 501 densely;

[0051] Multiple groups of first springs 603 are arranged between the bottom surface of the box body 501 and the sliding bottom plate 601. The box body 501 and the sliding bottom plate 601 are connected by multiple first springs 603. When the two arc-shaped rods 1207 drive the rubber hammers 1202 to alternately knock the box body 501 and the extension block 502, the box body 501 of the box body 501 generates slight vibration. On the premise of ensuring the stability of the model and cooperating with the knocking of the box body 501 by the arc-shaped rod 1207, the speed of vibrating the molding sand inside the box body 501 densely can be further accelerated;

[0052] After the molding sand inside the box body 501 is vibrated and compacted, the output ends of the four groups of second electric telescopic rods 1103 arranged on the cross plate 1102 retract, so that a pouring channel can be formed in the molding sand. Under the action of the sliding assembly 6 arranged on the upper surface of the mounting plate 4, the sand box 5 can be moved from one end of the upper surface of the mounting plate 4 below the fixing plate 7 to the other end. During this process, first servo motors are fixedly installed at the corresponding positions on both sides of the bottom surface of the mounting plate 4 and the driving gears 604. The output ends of the first servo motors are fixedly connected to the middle positions of the driving gears 604. When the first servo motors drive the driving gears 604 to rotate, the sliding bottom plate 601 is driven to slide on the upper surface of the mounting plate 4 under the meshing transmission of the driving gears 604 and both sides of the sliding bottom plate 601. Then, after the sand box 5 moves to the other end of the mounting plate 4, an existing pouring device arranged outside the supporting bracket 1 can pour the molten raw material of high chromium cast iron into the molding sand under negative pressure through the pouring channel generated by the retraction of the second electric telescopic rods 1103. The foam model disappears after contacting the high-temperature pouring material. After pouring, the transport vehicle 2 moves along the upper surface of the supporting bracket 1 to the blanking station. During this process, after cooling, the mud pump shell casting can be taken out from the inside of the box body 501 at the blanking station.
