Surface hardness is HRC62.5-64, and quenching centre hardness is HRC49.8-53, and the metallographic structure after quenching is quenched martensite tissue;
Tempering centre hardness is H RC44.5, and tempering metallographic structure is secondary troostite tissue, carburized layer thickness 1.5-1.8mm;
D. galvanizing by dipping:In 500 ± 50 DEG C of immersion plating temperature and immersion plating time it is 35 ± 10 by vibration transmission shaft carburized workpiece
Galvanizing by dipping operation is carried out under second, forms zinc coat.
Beneficial effects of the present invention:
Cooling device is not needed, vibration does not need brake, and simple in construction, energy-conserving and environment-protective, noise are low, long lifespan, are applicable
Various working requirement.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The present invention is better understood from for the ease of those skilled in the art, the present invention is done with specific embodiment below in conjunction with the accompanying drawings
Further illustrate, following is only exemplary not limit protection scope of the present invention.
Refer to the attached drawing 1, a kind of centrifugal frequency conversion excitation device, including base 8, vibrating motor 1, power transmission shaft 7 and two shake
Dynamic power transmission shaft 6;Vibrating motor 1 is arranged on base;Power transmission shaft 7 is installed on by the support of bear box 4 with drive bearing 3
On base 8, power transmission shaft 7 is connected by universal connecting shaft 2 with vibrating motor 1;Two vibration transmission shafts 7 are arranged in parallel, often
Individual one end of vibration transmission shaft 6 has cavity, and two bearings 5 coordinated with the gap of power transmission shaft 7 are provided with the cavity, and the other end is used
In on connection vibrated machine body or mould;The wherein axis of power transmission shaft 7 and the axis of vibration transmission shaft 6 is mutually perpendicular to, power transmission shaft 7
Axis and the axis of vibrating motor 1 are in same horizontal line.
The manufacture method of vibration transmission shaft 6 is as follows:
A. milling machine is processed:Choose material by standard size, and according to drawing requirement with milling machine milling into smooth cylinder;
B. cavity is formed:Cylinder is in lathe according to dimensioned cavity;
C. Carburization Treatment is heated:Cylinder by above step processing is subjected to heating Carburization Treatment, wherein, quench table
Surface hardness is HRC62.5-64, and quenching centre hardness is HRC49.8-53, and the metallographic structure after quenching is quenched martensite tissue;
Tempering centre hardness is H RC44.5, and tempering metallographic structure is secondary troostite tissue, carburized layer thickness 1.5-1.8mm;
D. galvanizing by dipping:In 500 ± 50 DEG C of immersion plating temperature and immersion plating time it is 35 ± 10 by vibration transmission shaft carburized workpiece
Galvanizing by dipping operation is carried out under second, forms zinc coat.
Production process of the present invention is as follows:
Vibrating motor 1 is by centrifugal force caused by high speed rotation, and moment is converted into exciting force, then by vibration transmission shaft
6 pass on vibrated machine body or mould, because the axis of vibrating motor 1 and the axis of power transmission shaft 7 are in same horizontal line, transmission
The axis of axle 7 and the axis of vibration transmission shaft 6 are mutually perpendicular to, and the oscillation trajectory of vibrated machine body or mould is in horizontal plane and vertical
Face projection be all straight line, thus can produce stereoscopic three-dimensional vibration, moment reach vibration require, powder or concrete etc. quickly,
Uniformly, closely knit cloth is in machine die.The machinery or mould big if necessary to connect vibration area, it is centrifugal can to connect more sets
Frequency conversion excitation device, the present invention can as the general exciting source of all kinds of vibrating machines, can be widely applied to mine, metallurgy, coal,
Electric power, building materials, chemical industry, casting, light industry etc. vibration in need machinery industry, be especially suitable for non-baking brick machine, block building machine,
Static pressure block machine, insulation blocks production line, forcing press, hydraulic machinery and mould pour machinery.
Above only describes the general principle and preferred embodiment of the present invention, those skilled in the art can be according to foregoing description
Many changes may be made and improves, and these changes and improvements should belong to protection scope of the present invention.
