Abstract
The utility model relates to a cylindrical roll shaft component surface alloy layer melting-casting device belonging to mechanical maintenance and surface strengthening equipment, wherein a casting mould is mounted on a cramping apparatus, an induction coil is sleeved on the outer portion of the casting mould, a casting workpiece is inserted in the center hole of the casting module, and a ring-shaped crucible casting cavity is formed between the other surface of the casting workpiece and the inner hole surface of the casting mould, an alloy hopper is mounted on a supporting stand, two ends of a conveying pipe are respectively communicated with the alloy hopper and the ring-shaped crucible casting cavity. The cylindrical roll shaft component surface alloy layer melting-casting device has the advantages of simple casting technique, even and continuous working, high working efficiency, excellent operation quality and wide application scope.
Description
Technical field
The utility model belongs to flight-line maintenance and surface-strengthening equipment, relates generally to a kind of processing units that cylindrical roll shaft element outside surface is carried out the founding alloy layer.
Background technology
Cold coating high frequency melting and coating technique appearred presetting in recent years, than prior art, it is higher to have efficient, the cladding layer surface is more smooth, process redundancy is less, cost is lower, cladding layer hardness and corrosion resistance are better, even can be according to advantages such as workpiece working condition designs, but because in the processing, employing will be desired the cladding workpiece surface earlier and carry out processing treatment, then with the powdered alloy of selecting to configure inorganic glue furnishing paste, be applied to workpiece surface in advance, drying, preheating, place horizontal single-purpose machine, carry out induction heating with radio-frequency induction coil, make the precoated layer cladding in workpiece surface, thereby reach the purpose that maintenance or piece surface are strengthened, in actual applications, except that in powder, adding a certain amount of reductor, also to consider to take off slag, its maximum shortcoming is that its precoated layer is in drying, preheating, links such as carrying are prone to peels off, in case localized delamination, the necessary full scale clearance of whole precoated layer, again handle, again coating causes unnecessary powdered alloy, the waste in man-hour, simultaneously, precoating requires evenly fine and close, otherwise the alloy layer thin and thick that makes is irregular, and the position processing content that has is excessive, may not get up owing to crossing thin processing in position a bit, quality is difficult for assurance, in addition, and in heat-processed, because the selection or the ratio of glue are improper, precoated layer very easily peels off or perk, cause the cladding failure, even workpiece is scrapped.The horizontal configuration of processed roll shaft class part, workpiece easily occurs bending and deformation in the founding course of processing, whole complete processing complexity.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at above-mentioned prior art, design provides a kind of cylindrical roll shaft element surface alloying layer smelting-casting equipment of novel texture, reaches the purpose of simplifying founding, assurance founding operation quality, reducing operating cost, raising operating efficiency.
Basic design of the present utility model is, a kind of cylindrical roll shaft element surface alloying layer smelting-casting equipment comprises support, anchor clamps and founding workpiece drive unit, equipped mold on anchor clamps, the induction line snare fits on the mold outside, the founding workpiece is inserted in the mold centre hole, between founding workpiece cylindrical outer surface and mold bore surface, be provided with the circular clearance, looping crucible type founding chamber, the alloy hopper is rack-mount, and the carrier pipe two ends are communicated with alloy hopper and annular crucible formula founding chamber respectively.Equipped valve on carrier pipe.
The utility model is except that the advantage that the founding process is simple, Job Operations is simple and easy continuously, operating efficiency is high, operation quality good, operating cost is cheap that has cylindrical roll shaft element surface alloying layer, also have following characteristics: 1, the perpendicular position of workpiece clamping makes workpiece thermal stresses flexural deformation tendency in heat-processed almost nil; 2, saved impregnation, take off slag agent selection and links such as precoating, drying, operating efficiency and success ratio greatly improve, and make that cladding layer is more even, process redundancy is littler, even can directly press the design requirements founding; 3, to be applied to single-piece component advantage in enormous quantities more obvious for present technique, as oil pumper plunger, mine hydraulic prop, milling train support roll etc.; 4, compared with the prior art, can make thicker cladding layer according to the workpiece working condition requirement.But the existing single cladding thickness that presets in the cold coating high frequency melting and coating technique is generally below 4.5mm, otherwise in cladding process, the cladding layer molten metal can produce trickling, drippage, this equipment can be according to the workpiece operating mode, design molded layer thickness, and by selecting suitable mold material, induction power supply frequency (as high frequency, intermediate frequency, power frequency), processing condition and parameters such as reductor, realize the big thickness founding of single, range of application is wider.
