Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pump shell casting, in particular to an intelligent casting island for mud pump shell production. BACKGROUND

[0002] As the core equipment in the fields of oil drilling, mine exploitation and river dredging, the shell of a mud pump needs to withstand the severe scouring of high-pressure mud, abrasive wear and chemical corrosion for a long time, and has extremely high requirements for corrosion resistance, impact resistance and structural reliability of the material. At present, high chromium cast iron (such as Cr26 and Cr28 series) has become the mainstream casting material for mud pump shells due to its excellent wear resistance and corrosion resistance. However, the high-carbon and high-chromium composition of high chromium cast iron leads to high melting temperature (1500-1600℃), poor fluidity and large shrinkage, and defects such as shrinkage, porosity and cracks are easily generated during casting due to insufficient compactness of the sand mold or uneven cooling. In addition, the mud pump shell usually has a complex runner structure, an asymmetric flange interface and a sudden change in thickness, and it is difficult for traditional sand casting to accurately reproduce its geometric characteristics. The lost foam casting technology (EPC) provides an effective way to solve the molding of complex structures through the way of foam model sand embedding.

[0003] In the lost foam casting process, the uniformity of the compactness of the sand mold directly determines the quality of the casting. In the prior art, on the one hand, the vibration mechanism in the sand vibration process usually adopts single vertical vibration or mechanical compaction, and the vibration force is concentrated in a local area, resulting in a significant gradient of sand mold compactness, large gaps between sand particles in the thin-walled area, and easy penetration of the metal liquid into the sand mold to form mechanical sand sticking during pouring. On the other hand, under the rigid fixing mode of the sand box, the vibration energy transmission efficiency is low, the sand box resonance effect is weak, the gaps between some sand are large, the gas discharge path is blocked, and the casting porosity defect rate is increased.

[0037] When the conveying vehicle 2 moves to the sand adding station, part of the sand is added into the inside of the sand box 5 through the existing sand adding device on the sand adding station. At this time, the height of the fixing frame 10 arranged on the upper end of the first electric telescopic rod 3 is lowered by adjusting the first electric telescopic rod 3. The first connecting seat 804 fixedly installed on the upper end of the lifting column 803 contained in the driving assembly 8 is moved up and down by driving the lifting column 803 to move up and down.

The end of the first swing rod 1201 is provided with a sliding groove matched with the circular shaft, and the sliding connection between the second connecting seat 1203 and the first swing rod 1201 is realized by the sliding of the circular shaft in the sliding groove. 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, and under the action of the lever principle, the end of the arc-shaped rod 1207 provided with the rubber hammer 1202 rotates downward around the connecting position of the first swing rod 1201 and the extension frame 1101, so that the rubber hammer 1202 provided at the end of the arc-shaped rod 1207 can knock the upper outer wall of the box body 501. When the second connecting seat 1203 moves downward, by pressing the end of the second lever 1205 connected with the second connecting seat 1203 downward, the other end of the second lever 1205 is lifted upward, and the connection mode between the second lever 1205 and the end of the second swing rod 1206 is the same as that 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 provided at the end of the second swing rod 1206 swings downward to drive the rubber hammer 1202 provided at the end of the arc-shaped rod 1207 to knock the extension block 502.

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 produces slight vibration, which can further accelerate the vibration of the sand in the box body 501 under the condition of ensuring the stability of the model and the knocking of the arc-shaped rod 1207 to the box body 501.

[0052] When the sand inside the box 501 is vibrated and compacted, the four sets of second electric telescopic rods 1103 arranged on the cross plate 1102 retract, forming a pouring channel in the 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 below the fixed plate 7 to the other end on the upper surface of the mounting plate 4. During this process, the bottom surface of the mounting plate 4 is fixedly installed with first servo motors on both sides corresponding to the driving gear 604. The output end of the first servo motor is fixedly connected to the middle position of the driving gear 604. When the first servo motor drives the driving gear 604 to rotate, the sliding bottom plate 601 slides on the upper surface of the mounting plate 4 under the meshing transmission action of the driving gear 604 and the sliding bottom plate 601 on both sides. When the sand box 5 moves to the other end of the mounting plate 4, the existing pouring device arranged outside the support frame 1 can pour the high-chromium cast iron melt into the sand inside the box 501 through the pouring channel generated by the retraction of the second electric telescopic rod 1103 under negative pressure. After the foam model contacts the high-temperature pouring material, it disappears. After pouring, the conveying vehicle 2 moves along the upper surface of the support frame 1 to the discharging station. During this process, after cooling, the slurry pump shell casting can be taken out from the inside of the box 501 at the discharging station.
