Abstract
The invention relates to a production method of a mud pump composite cylinder sleeve for petroleum drilling engineering. The method comprises the implementation steps of pouring the composite sleeve, heat-insulating annealing, machining, inner hole intermediate frequency quenching, cutting machining, honing and the like, breaks through the commonly adopted process method for manufacturing the composite cylinder sleeve in an embedding manner, reduces the machining process close to 2/3 under the condition of ensuring the quality and the performance of the product, saves 30 percent of raw materials and energy and 40 percent of machining cost, and greatly reduces the production cost. The process can greatly improve the production efficiency, reduce the cost, obtain considerable economic benefit and is suitable for popularization and application.
Description
The present invention relates to a kind of production method that is used for the main accessory mud slurry pump cylinder jacket of petroleum drilling engineering special equipment.
Mud slurry pump cylinder jacket is the requisite main accessory of petroleum drilling engineering special equipment, because its work under bad environment is easy to wear, thereby consumption is big.In order to satisfy need of work, improve abrasion resistance properties, reduce production costs, develop both at home and abroad in recent years, produce by two or more metal inserts to together composite cylinder jacket.At present, the production technology of this kind composite cylinder jacket mainly is that hot again insert is to becoming the setting type cylinder sleeve together after adopting inside and outside cover to pour into a mould respectively, process.Its shortcoming is that the whole production process is many and numerous and diverse, need expend a large amount of human and material resources, financial resources, and dissimilar waste products such as insert ftractures, press-offs, cutting ferrule very easily occur, thereby cost is still higher.
The object of the present invention is to provide simple, easy to implement, the lower-cost mud pump composite steel bushing production method of a kind of operation.
Mud pump composite steel bushing production method provided by the present invention comprises the compound cover of cast, insulation annealing, machined, endoporus mid frequency induction hardening, machining, honing operation, and its enforcement, operating procedure and main points are as follows:
1, pours into a mould compound cover.Utilize the molten steel of two kinds of compositions of two medium-frequency induction furnaces melting simultaneously, on the horizontal centrifugal casting machine of J513 type stepless speed regulation, pour into a mould.During cast, use quick galvanic couple thermometric, the overcoat pouring temperature is 1520--1550 ℃, and interior cover pouring temperature is 1380-1420 ℃.Centrifuge speed is selected according to cover class diameter, and cast overcoat diameter rotating speed when 240-300mm is 500-650 rev/min.When the overcoat pouring molten steel to 3/4 the time, add the interface protective agent of 300-500 gram calcic sodium ion in the remaining 1/4 overcoat molten steel, overcoat has been watered; 20-35 brought up to 820 rev/mins with rotating speed and pours into a mould second layer molten steel again after second at interval; If three kinds of compound covers of composition molten steel, then interval 20-35 waters compound steel water after second again, and Jiao Zhu one deck molten steel is interior cover molten steel at last.Herein, adjust, control according to mold temperature concrete blanking time.
2, insulation annealing.After all molten steel watered for 10 seconds, toward mold top-pour water cooling, the mold commentaries on classics was stopped after 2 minutes, is cut off the water, depanning.After the foundry goods depanning, put into insulation ash insulation annealing immediately.
3, machined.Rough turn cylindrical on the C6163 lathe, rough turn both ends of the surface, car endoporus again.
4, endoporus intermediate frequency liquid extract.Utilize intermediate frequency power supply and a quenching machine of 160KW, a 8000HZ to implement.Earlier cylinder sleeve is preheating to 400-450 ℃, strengthen electric current then and make inner surface of cylinder liner reach 980 ± 10 ℃ of hardening heats, and quench as quenching medium limit heating edge, through about 2 minutes, promptly finish quenching technical with air-cooled or water-cooled, quench hardened case hardness can reach more than the HRC60, and the degree of depth reaches more than the 2mm.
5, machining.Finish turning cylindrical on 6163 lathes, finish turning both ends of the surface, car chamfering.
6, honing.The grinding endoporus is until reaching specification requirement on the M4220 honing machine.Mud pump composite steel bushing production method provided by the invention has broken through the common way that domestic and international setting type is made composite cylinder jacket, guaranteeing under product quality, the performance situation, reduced nearly 2/3 manufacturing procedure, and can save the processing charges of 30% raw material, the energy and 40%, production cost is reduced significantly.Utilize this kind production technology to enhance productivity greatly, reduce cost, obtain considerable economic, be suitable for and apply.
Fig. 1 pours into a mould the schematic diagram of compound cover operation for the invention process.Among the figure, label " 1 " is a water bucket, and " 2 " are moulding, and " 3 " are baffle plate, and " 4 ", " 5 " are respectively the overcoat and the interior cover of cast, and " 6 " are casting machine.
Fig. 2 is the schematic diagram of the invention process endoporus mid frequency induction hardening operation.Among the figure, label " 7 " is the intermediate frequency power supply inductor, and " 8 " are pressing plate, " 9 " are centralizer, and " 10 " are magnetic conductor, and " 11 " are induction coil, " 12 " are cooling agent, and " 13 " are the quenching machine support, and " 4 ", " 5 " are respectively the overcoat and the interior cover of composite cylinder jacket.
