Abstract
The invention discloses a manufacturing process of a rotating mandrel of a rotor drying machine. The manufacturing process comprises the following steps: firstly, reeling a steel plate with thickness into a plurality sections of shaft barrels and bushes by using a plate reeling machine; secondly, turning the end part of each section of shaft barrel to form a welding groove by using a machine tool; thirdly, splicing and welding: butting each section of shaft barrel one by one, mounting each bush on the inner wall between the adjacent sections of shaft barrels, and performing layered welding to form an integrated body; fourthly, eliminating stress; and finally, welding a shaft head and a shaft tail to the shaft barrels. The manufacturing process is simple and short in manufacturing period; the mandrel adopts steel plate reeling and sectional welding, so the mandrel is not sensitive to heat and does not generate hardenability; the bushes are arranged in the barrel shafts and the sectional deformation is controlled, so that the deformation of the whole shaft is controlled, the rotating torque of the shaft is increased, the service life of bearings at two ends is prolonged, and the production cost and the using cost are low.
Description
Technical field
The present invention relates to a kind of particieboard and pole particle drying equipment field of machining of belonging to, be specifically related to the manufacturing process of a kind of rotor drying machine rotation mandrel.
Background technology
Both at home and abroad the small powder of fines wood chip wood shavings and pole pulverizing is dried at present, one of capital equipment is the rotator type drying machine.Its mandrel rotates, and above have the multi units tube bundle, inner logical steam of tube bank or conduction oil are dried processing by the heat conduction to the raw material that are in contact with it.
The mandrel that this dry equipment critical piece is a rotor, it is to be made by big thick-walled pipe because the thick-walled pipe domestic production is less, and must have a certain amount ofly could order goods, the production cycle is long again.The imported raw material price is expensive, and the cycle is also very long, does not satisfy the requirement of user's production cycle, and therefore great majority are selected the material of little section steel works for use, but material physics and mechanical performance instability fracture accident occurs through regular meeting, and service life is short, causes cost to raise.
Summary of the invention
Technical problem at above-mentioned existence the objective of the invention is: it is simple to have proposed a kind of manufacturing process, and fabrication cycle is short, the low and long service life of cost, the rotor drying machine rotation mandrel that intensity is high.
Technical solution of the present invention is achieved in that the manufacturing process of a kind of rotor drying machine rotation mandrel, comprises following making step:
The first step, the steel plate that will have thickness with veneer reeling machine is rolled into plurality of sections beam barrel and lining;
In second step, every section beam barrel end is gone out bevel for welding through lathe turning;
In the 3rd step, splicing welding: every section beam barrel is docked one by one, and lining carries out layering and is welded into integral body after being loaded between the adjacent segment beam barrel on the inwall;
In the 4th step, eliminate stress: the beam barrel that will splice after welding carries out annealing in process;
At last, spindle nose, axle tail are welded on the beam barrel.
Preferably, described every section beam barrel adopts the steel plate of different-thickness to roll.
Preferably, described spindle nose, axle tail are welded on the beam barrel, adopt and beat screwed hole in beam barrel end, both sides, at first, adjust the axiality of spindle nose, a tail, weld after reaching requirement beam barrel and spindle nose, axle tail bolting, after welding together, again with disassembling bolts, screwed hole plug welding weldering labor.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
The manufacturing process of rotor drying machine of the present invention rotation mandrel, manufacturing process is simple, and fabrication cycle is short, and mandrel adopts steel plate to roll the segmentation welding, insensitive to heat, and do not produce quenching property, and between beam barrel inside, add lining, the deflection of control segmentation, thereby control the deflection of whole axle, therefore increased the moment of torsion that axle rotates, increased the service life of bearings at both ends, production and use cost are low.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of rotor drying machine of the present invention rotation mandrel;
Wherein: 1, beam barrel; 2, lining; 3, bevel for welding; 4, spindle nose; 5, axle tail; 6, screwed hole.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be the manufacturing process of a kind of rotor drying machine of the present invention rotation mandrel as shown in Figure 1, comprise following making step:
A, the steel plate that will have thickness with veneer reeling machine are rolled into plurality of sections beam barrel 1 and lining 2, because each section beam barrel 1 suffered requirement of strength difference can adopt the steel plate of different-thickness to roll respectively, reach equal strength and distribute, and thermal expansion influence is little;
B, every section beam barrel 1 end is gone out bevel for welding 3 through lathe turning, guarantee firm welding;
C, splicing welding: every section beam barrel 1 is docked one by one, and lining 2 carries out layering and is welded into integral body after being loaded between the adjacent segment beam barrel 1 on the inwall.Before the splicing welding, can carry out the turning of inside and outside footpath and length to beam barrel 1 and the inner liner 2 spooled respectively as requested, make in connection, assembly unit process, when being positioned in the middle of two beam barrels, inner liner 2 guaranteed the axiality between the adjacent beam barrel 1, and accurate positioning, convenience operation have been played;
D, eliminate stress: the beam barrel 1 that will splice after the welding carries out annealing in process, to lower the residual stress that produced that is shaped;
F, with spindle nose 4, the axle tail 5 be welded on the beam barrel.Spindle nose 4, axle tail 5 are welded on the beam barrel of both sides, employing is beaten screwed hole 6 in both sides beam barrel 1 end, at first beam barrel 1 and spindle nose 4, an axle tail 5 use bolting, adjust the axiality of spindle nose 4, a tail 5, weld after reaching requirement, after welding together, with disassembling bolts, screwed hole plug welding weldering labor makes to have good welding performance equally in installation process again, and accurate positioning, can guarantee that the whole circumference of mandrel is beated to be not more than 3mm.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
