Abstract
The invention provides a manufacturing method of a bimetal barrel. The process procedures of the invention are that: a matrix(6) is processed and then is filled with alloy powder(7); and then the two ends of the matrix(6) will be sealed by sealing caps(2,9) to be heated and fused and then is cut and molded after cooled; wherein, a core mould(4) will be arranged inside the matrix after the matrix is processed, and the alloy power is filled in the clearance between the core mould and the matrix; after the matrix is cooled, the core mould will be removed, and then the matrix will be cut and molded. The manufacturing method of the bimetal barrel provided by the invention adopts a mould casting method to replace a centrifugal casting method, and the mould casting method is that alloy layer is covered on the inner wall of the barrel matrix. The mould casting method does not need centrifugal operation or bushing processing, which simplifies the manufacturing process, and does not need cutting off excessive material, particularly the alloy material, which saves the material consumption.
Description
What technical field the present invention relates to is a kind of manufacture method of bimetal charging barrel, is the device in a kind of device of plastic processing.
The background technology barrel is important components in the plastics plasticizing apparatus, and the branch of single hole barrel and diplopore barrel is arranged, and the branch of bellmouth barrel peace shape hole barrel is arranged again.Service life and bearing capacity in order to improve barrel save material and energy consumption, and people have proposed a kind of bimetal charging barrel.In the former operation, this one deck special alloy all is compounded on the matrix with centrifugally cast method, so-called centrifugal casting, be to process matrix earlier and in matrix hole, pour into alloy powder on demand, with heating the alloy powder fusion behind the capping sealing two ends, then the barrel matrix is lain on the roller, under the driving of roller, allow matrix comply with the rotation of its axis, make in its body liquid alloy produce centrifugal force and invest on the matrix hole wall cooling gradually and form alloy-layer at the matrix hole wall.But this manufacture method not only manufacture process is comparatively complicated, and can only be applied to make in single hole and the barrel that be parallel hole.This because of: the one, the diplopore barrel is that two holes link to each other side by side, can not carry out composition operation by spun casting as the single hole barrel, the 2nd, spun casting is resulting to be isometrical endoporus, and aperture, bellmouth two ends differs bigger, then the special alloy amount that need cut the large aperture end is very big, causes the waste of material, energy consumption and technology.For this reason, someone has proposed the spun casting of alloy-layer elder generation is inlayed after the machine-shaping again the method for the edge cover method processing bimetal charging barrel that is enclosed within the matrix on a lining, though but this method solves the manufacturing of diplopore barrel, but still there is the defective of centrifugal casting and procedure of processing is more, waste of material is bigger.
Summary of the invention is at above-mentioned defective, and the present invention will solve centrifugal casting especially to inlay cover manufactured bimetal charging barrel complex process, technical problem that feed consumption is bigger, thereby a kind of manufacture method of bimetal charging barrel of simple economy is provided.
The manufacture method of bimetal charging barrel provided by the invention, its processing step is matrix processing, pour into alloy powder and with cutting forming after capping sealing two ends and heating and melting, the cooling, wherein after processing matrix, a core to be installed in the matrix, and alloy powder is in the space that is circulated between core and the matrix, after removing core after the cooling again through cutting forming.
The manufacture method of bimetal charging barrel provided by the invention, said matrix at one end grows one section, is used to store alloy powder.The unit weight of alloy is greater than the unit weight of alloy powder after the fusion, so will there be more space to store alloy powder replenishes the alloy powder of being stored in the space between core and the matrix in order to alloy water after the fusion deficiency.
The manufacture method of bimetal charging barrel provided by the invention, core rod is made for the metal material identical with matrix, and core is installed in the capping of two ends by supporting construction, and said supporting construction is the strip metal member that connects capping and core.For reducing the core manufacture difficulty, improving core and make precision, save core Production Time, more can horizontal form heat, core is made of metal, and be installed in the capping of two ends with supporting construction, core can avoid the alloy-layer on the matrix inwall to stay vacancy to be suspended in the matrix with the contacted support construction supports of base wall when making horizontal heating.
The manufacture method of bimetal charging barrel provided by the invention, core rod is made for the metal material identical with matrix, and elder generation coats one deck precoated sand before in being installed to matrix outside core rod, with conveniently stripped and do not need fully core to be removed with the method for cutting, the outsourcing of metal core covered one deck precoated sand with after intercepting the alloy powder fusion with high temperature equally in the combining of core.
The manufacture method of bimetal charging barrel provided by the invention, when heating and melting or behind heating and melting, matrix is vertically placed, and can be before cooling matrix be placed on the jarring machine and shake, this operation is to be convenient to alloy water be easier to be packed between core and the matrix in the space and get rid of presumable bubble.
The manufacture method of bimetal charging barrel provided by the invention, replace centrifugal casting to come with die casting to barrel matrix inwall covering alloy layer, do not need centrifugally operated or edge cover processing and simplified manufacturing process, do not need to cut especially alloy material and saved material consumption of too much material.
Description of drawings Fig. 1 is the apparatus structure schematic diagram of one embodiment of the invention before heating;
Fig. 2 is that one embodiment of the invention is at cooled apparatus structure schematic diagram.
The manufacture method of the bimetal charging barrel that the specific embodiment 1, this example provide, its processing step is earlier with matrix machine-shaping, again a core is installed in the matrix and adds a cover an end capping, pour into alloy powder then in the space between core and matrix and add a cover other end capping, in heating furnace, heat subsequently, make the alloy powder fusion, take out heating furnace cooling again, after the cooling core is removed, at last with matrix inwall alloy surface cutting forming and make bimetal charging barrel on request.
2, the manufacture method of the bimetal charging barrel that provides of this example, its processing step and last example are together, wherein an end of matrix grows one section, be that matrix is longer than the actual length that requires, and core is made by physical length, there is a cavity can be used for storing alloy powder at matrix than long one section of core like this, the deficiency that can replenish the alloy powder of being stored in the space between core and the matrix in order to alloy water after the fusion.What after the cooling this is grown one cuts off.
3, the manufacture method of the bimetal charging barrel that provides of this example, its processing step is with example 1, wherein core rod is made for the metal material identical with matrix, and be to be installed in the capping of two ends by the strip metal member, earlier at core two ends fixing metal bar, during core to be installed this metallic rod and two ends capping are fixed when making core.
