Abstract
This invention discloses a method for casting a cane crushing roller shell with a natural pattern. An original casting box is employed and the natural pattern is placed in a common casting box or a pit and the outer wall of the crushing natural pattern is filled with clay moulding sand while a moulding system is installed for moulding. A central sleeve shaft of the crushing roller shell is filled with refractory materials or pottery cores. The moulding sand or resin sand, or water glass sand or other kinds of chemically self-hardening sand are filled between the natural pattern and the casting box and the natural pattern can be left in a sand mould without taking the natural pattern out through air drying or temperature increasing or the natural pattern can be burnt, followed by installing the moulding system to mould. The natural pattern indicates a mold made of foamed material or other materials through gasification under high temperature. The invention saves the procedures of moulding taking and pottery core production without casting box turnover and mould separation; the casting part produced by the casting method is of good quality, no burr and good surface smooth finish; in addition, as the procedure of making a pottery core frame is saved, the invention can significantly simplify the producing process and labor intensity, and has less investment, practicality and easily-mastered techniques.
Description
Technical field
The present invention relates to a kind of manufacture method of cane sugar manufacture plant equipment, especially a kind of casting method of cane pressing roller of sugar shell.
Background technology
The most basic purpose of cane sugar factory milling shop is extracted sugarcane juice exactly.Reach this purpose, must finish two tasks: the one, the sugarcane juice in the sugarcane is squeezed out as far as possible, and the sugarcane juice of squeezing out is discharged.Cane pressing roller of sugar is exactly the juice that is contained in sugarcane inside in order to extrusion, its the most basic version is the three-roller type pressing device that comprises a top roller and two bottom rollers, three one of pressure roller are called top roller in the above, one of two bottom roller in front be called preliminary roller, a roller behind the title of back.Top roller and bottom roller respectively comprise the cylindric roller shell of a forged steel axle and alloy pig iron casting, and roller shell outside is along even some the V-type teeth that distribute of circumference, and sugarcane is fed between top roller and the bottom roller and squeezed, and the inner contained sugarcane juice of sugarcane is squeezed out to be discharged in the juice-collecting tank.Finish the extraction of the juice task.Because original design and process technology fall behind, the applicant introduces the lost foam casting advanced technologies in the patent of first to file and presses the roller production field, the irrealizable technology of original old technology is achieved, technology has been advanced major step, but should disappearance mould production technology complexity, equipment investment is big, and the general difficulty of producing has a strong impact on applying of this technology.
Summary of the invention
The purpose of this invention is to provide and a kind ofly make pressure roller shell production small investment, do not need to roll up new equipment, can all utilize old sandbox and original mo(u)lding equipment, and advanced technology, the casting preparation method grasped easily, change the deficiency of traditional machining, the sugar-cane crusher shell that casting is come out can satisfy the production demand.
The technical solution used in the present invention is:
Utilize original old sand case, natural pattern is placed in the common sandbox or melt pit, tamp with loam moulding sand, set up the casting system casting in press for extracting juice roller natural pattern periphery.The position of roller shell center sleeve, filling fire resisting material or make the mud core in addition.Fill molding sand or resin sand or water-glass sand or other any chemical self-hardening sand in the middle of natural pattern and the sandbox, through air-dry or heat, natural pattern can be stayed in the sand mold, as long as heap sand is filled up tamping, even if moulding finishes, can take out natural pattern, also natural pattern can be burnt, load onto the casting system casting then.Natural pattern is meant the mould made from foamed material, or makes with any material that is subjected to can gasify behind the high temperature.
The present invention compares with traditional sand casting, and the program that its advantage has been lacked delivery and produced the mud core must mould turnover and somatotype yet, and the casting quality that casting is come out is good, do not have a limit, and surface smoothness is good; Do not need to make the mud arbor, play the dry mud core of mud core, the mud core is installed, also needn't clear up the mud core at last, production process and labour intensity have been simplified greatly, also needn't resemble to make the disappearance mould and add a big cover vacuumizing device, large quantities of sealed special sandboxes, large quantities of special dry sands, a whole set of jolt mo(u)lding machine and molding sand process for producing line.Small investment, technology is easily grasped, and practicality is the method that roller is pressed in a kind of new casting.
Description of drawings
Fig. 1 is the casting sugar-cane crusher shell with real mould structural representation.
Shown in the figure, 1, press the roller natural pattern; 2, press the hollow part of roller; 3, roller shell mould outer circumference surface; 4, the outer dope layer of roller shell mould; 5, common sandbox or melt pit; 6, heap sand (molding sand that common moulding is used or resin sand, chemical self-hardening sand etc.).
The specific embodiment
Now reaching embodiment in conjunction with the accompanying drawings describes:
The present invention makes foam mould natural pattern 1 earlier, evenly coat a thick layer of fireproof coating 4 in natural pattern 1 outside, then with natural pattern and coating oven dry, temperature is controlled at and can not allows foam softening transform (it is below 100 ℃ that the present invention selects temperature for use), natural pattern after the oven dry is put in sandbox or the melt pit 5, this sandbox is put into melt pit with natural pattern after can utilizing original various old sand case or directly digging melt pit, layering heap sand 6 tampings then, moisture content in the molding sand will lack especially, simultaneously needn't delivery after the tamping, therefore not being afraid of it strides case.Also can after the molding sand tamping, the foam mould be burnt, preferably with resin sand or waterglass moulding.Intermediate hollow partly 2 when pressing the roller outer circumference surface and filling molding sand, is also filled hollow part, after having filled, digs some pores on sand mold more, treats dried a period of time, or directly heats and burn the foam mould to 98 ℃ and just can cast.
The method of roller is pressed in this manufacturing, has simplified a lot of operations than the method that existing system is pressed roller, and it does not need delivery, need not make the mud core, does not need casting box, and it is good to close the sandbox casting quality, and the surface does not have the limit, saves investment, can utilize original used equipment, old heap sand.
The method of roller is pressed in this manufacturing, and also molded to make the method for pressing roller superior than disappearing, and at first it does not increase special-purpose sealed sandbox, and the quantity of this equipment is quite big, much overlap sandbox, and requires highly, seal, and joins the vacuum treasured again, invests very big.Also will prepare the series mechanical electric equipment of vacuum, this pen investment is also very big.The heap sand of its usefulness is special dry sand, and consumption is also very big, and price is quite expensive, more than 1,000 yuan one ton in mound sand, and to go up the production line that a dry sand is handled cooling, this also is a very big investment.Adopt the inventive method can replace it fully.
