Description
Technical field
The utility model is related to steam turbine, more particularly to steam turbine mounting and adjusting pad perforation structure.
Background technology
The installation of turbine body is a very accurate job, with the increasingly raising of steam turbine mounting process, one
A little traditional techniques have been no longer appropriate for the technological requirement of turbine body installation, and the installation of steam turbine is gap, a relative number
According to the process of adjustment, the deviation requirement of axial center is controlled within 0.02mm, through-flow gap requirement control ± 0.05mm with
It is interior, and the adjustment of these data is all realized by increasing and decreasing strong point pad, pad is by a thicker rigid gasket and tune
Whole stainless steel gasket is constituted, and is fixed by screw, and the thickness of the pad of adjustment stainless steel has：0.03mm、0.05mm、
0.08mm, 0.10mm, 0.15mm, 0.20mm, 0.30mm etc., pad fix (conventional specification is M4-M24) by screw, need
Will the perforate on pad, and the current perforate system of cutting using scissors by hand, and the hole of below diameter 20mm can only be cut to be open
Form, by the inadequate specification of hammer-shears drilling, shim size can not be controlled preferably, and easily cause deformation of pad etc.
Problem, causes the phenomenons such as pad unbalance stress.
Utility model content
The purpose of the utility model first is to provide the perforation structure of steam turbine mounting and adjusting pad, by setting for the structure
Put, scissors can be replaced, the problems such as system lack of standardization, mutability is cut in solution, it is ensured that pad adds uniform force after steam turbine；Drift is beaten
Orifice ring bottom applies shearing force to pad simultaneously, so makes the stainless steel gasket come than one-sided form drift, cylindrical shape drift
Make come stainless steel gasket is more smooth, around hole without crimping, deformation situations such as.
In order to reach above-mentioned purpose, the utility model is adopted the following technical scheme that：
The perforation structure of steam turbine mounting and adjusting pad, including punch head, with the big small holes of different-diameter first
Template and gasket plate, located at the lower section of the first template, the bottom of punch head is provided for the punching to gasket plate punching to gasket plate
Ring, punch head is punched out through the first template to gasket plate under external force；By the setting of the perforation structure, branch can be used
Member supports gasket plate, punch head is located at the hole top of the first template, and certain active force is applied by punch head, so that
Gasket plate is punched out, the pad required for forming steam turbine mounting and adjusting, gasket plate is stainless sheet steel.
Wherein, the punching ring is reversed round bench shaped, is so easy to form a shearing force to gasket plate, and stress more collects
In, so that convenient to gasket plate punching.
Or, in cone shape at the punching ring boring, or circular shape, this structure setting punching ring
Bottom is more sharp, convenient to gasket plate punching；Or, it is a ring body shape that punching ring inside is smooth.
The punch head includes at least two sections connected bearing pins, and the pin diameter being connected with the punching ring is less than pin in addition
The diameter of axle, in punching, the bearing pin of top forms a step to such punch head with the bearing pin junction of bottom, by step
Top bearing pin is stuck in the upper surface of the first template, after facilitating punching, punch head is taken out.
The power that manpower is used for required for applying punching is removed, punch head dismounting movable with lowering or hoisting gear sets, rises
The rapid decrease of falling unit drives punch head to be punched out gasket plate.
The bearing pin length being connected with punching ring can so realize that punch head enters to gasket plate more than the thickness of the first template
Row punching.
The punching ring is Nitrizing Treatment part, so as to strengthen the abrasive resistance of punching ring, improves its service life.
Additionally, the shape of punching ring can be toroidal or square configuration.
In order to ensure the stability of punching, be provided with the second template below the gasket plate, the shape of the second template with
The shape of the first template is identical, is coordinated with the second template by the first template and gasket plate is clamped, to facilitate to pad
Obtain；For convenience to the fixation of gasket plate, the top of the second template sets fluted, can be by under gasket plate and the first template
Half section is placed in groove.
The beneficial effects of the utility model are：
1) it is set to reversed round bench shaped or internal in cone shape by by punching ring, all significantly enhances punching
The acuity of ring bottom, fast and easy punching.
2) by the setting of the first template and the second template, it is easy to the clamping to gasket plate, keeps stabilization, it is convenient to pad
The punching of plate.
3) setting of whole perforation structure, is capable of achieving quick, the accurate acquisition to pad, and the smooth feelings of pad are effectively ensured
Condition.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the structural representation one of punch head in the utility model；
Fig. 3 is the structural representation two of punch head in the utility model；
Wherein：1. punch head, 2. punching ring, 3. the first template, 4. the second template.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clear, complete description.
