Abstract
The utility model relates to a loading device for the manual soldering of hard alloy slices, which is applied to the on-site manual soldering of anticorrosive stellite alloy slices of a final stage moving blade on a steam turbine. The loading device for the manual soldering of hard alloy slices comprises a lever, a positioning screw, a slide block, a steel bar and a scale, wherein the front section of the lever is bent into an arc-shaped line and is provided with a bolt hole, and the positioning screw is arranged in the bolt hole; the middle section of the lever is provided with the slide block connected with the steel bar, and the other end of the steel bar is provided with the scale; the back section of the lever is provided with a handle, and the scale is arranged in front of the scale. The slide block is provided with a ceramic press head, and the lever is formed by bending a spring steel. The utility model has advantages of simple structure and convenient operation, and loading points of the utility model are made of ceramic, so that stellite alloy slices can not be quenched in loading process.
Description
(1) technical field
The utility model relates to the manual soldering charger of hard metal tip, is applied to the charger of the on-the-spot manual soldering of steam turbine last stage movable vane corrosion protection stellite alloy film.
(2) background technology
The on-the-spot repaired by hand of steam turbine last stage movable vane corrosion protection stellite alloy film, traditional method are to adopt locking pliers to load, and can not accurately control loaded load because locking pliers loads, and cause loading inhomogeneous, and stellite alloy film comes off, ftractures.When the size that clamps when steam turbine last stage movable vane stellite alloy film actual needs reduced, owing to adopt locking pliers, clamping size and clamping force can't be adjusted, and erosion protection sheild and blade can not be clamped, caused the joint clearance of brazing excessive and influence brazing quality, came off easily; If clamping force is adjusted very greatly, when brazing temperature is very high, is in erosion protection sheild under the red heat state and holds very tightly with locking pliers suddenly, make the erosion protection sheild chilling, very unfavorable for having hot short erosion protection sheild, often there is crackle to occur in locking pliers clamping place.For locking pliers, each use all needs dismounting; The loading of locking pliers is by clamp stud, the operation of different locking pliers and different people, its clamping force difference; The locking pliers clamping part is a metal, loads under stellite alloy film high temperature, can cause the chilling to stellite alloy film, makes the stellite alloy film cracking.
(3) summary of the invention
The purpose of this utility model is to provide a kind of hard metal tip manual soldering charger, this apparatus structure is simple, easy to use, load(ing) point is a ceramic material, can the chilling stellite alloy film in loading procedure, result of use is good, thereby has overcome the defective of existing locking pliers loading tool.
The utility model is achieved in that the manual soldering charger of a kind of hard metal tip, it is characterized in that comprising lever, dog screw, slide block, bar steel, scale, the lever leading portion is bent into the arc molded lines, the lever leading portion has screw, and dog screw is housed in the screw, and slide block is equipped with in the lever stage casing, slide block connection strap steel, the bar steel other end is equipped with scale, and the lever back segment is a handle, before scale places handle.
The manual soldering charger of above-mentioned hard metal tip is equipped with ceramic pressure head on the described slide block.
The manual soldering charger of above-mentioned hard metal tip, described lever is bent by spring steel and forms.
The utility model is by lever and the scale that is loaded on the bar steel, determines to be carried in the size of the loading force on the hard metal tip.Lever is divided into leading portion, stage casing and back segment, and the arc molded lines that the lever leading portion bends meets steam turbine last stage movable vane convex surface molded lines, is used to locate last stage movable vane; Slide block is equipped with in the lever stage casing, and slide block connection strap steel is fixed in bar steel one end on the lever, on the slide block ceramic pressure head is housed also simultaneously, by ceramic pressure head hard metal tip is loaded, can not reduce the brazing temperature that alloy sheet loads the position rapidly, help guaranteeing brazing quality; The lever back segment is a handle, is convenient to operating personnel to the lever application of force.Front at handle also has scale, and scale is contained in an end of bar steel, and the bar steel is positioned at lever one side.Pull lever handle, just know what of loaded load, and the quantified controlling of on-load pressure, thereby guaranteed the uniformity of loaded load, improved the result of use of charger by scale.
(4) description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the manual soldering charger of a utility model hard metal tip structural representation;
Fig. 2 is the upward view of Fig. 1.
Among the figure: 1 lever, 2 dog screws, 3 slide blocks, 4 ceramic pressure heads, 5 steel, 6 scales; 10 lever leading portions, 11 lever stage casings, 12 lever back segments (handle).
(5) specific embodiment
Referring to Fig. 1, Fig. 2, the manual soldering charger of a kind of hard metal tip comprises lever 1, dog screw 2, slide block 3, ceramic pressure head 4, bar steel 5, scale 6.Lever 1 is bent by spring steel and forms, and lever leading portion 10 is bent into the arc molded lines, and this molded lines designs according to steam turbine last stage movable vane admission end camber line; Lever leading portion 10 has screw, and dog screw 2 is housed in the screw, by adjusting the extension elongation of dog screw 2, can adjust the position of ceramic pressure head 4, makes its soldering that is applicable to different in width blade stellite alloy film load requirement.In the present embodiment, lever leading portion 10 is independent spring steel, bends the back and connects through being weldingly connected with lever stage casing 11.Slide block 3 is equipped with in lever stage casing 11, slide block 3 connection strap steel 5, and bar steel 5 other ends are equipped with scale 6, and ceramic pressure head 4 is housed on the slide block 3, and during soldering, load is delivered on the stellite alloy film by ceramic pressure head 4, makes alloy sheet and blade soldering together.Lever back segment 12 is a handle, before scale 6 places handle 12, can know the size of knowing clamping force exactly by scale 6 scales in the brazing process.Because in pre-stage test work,, sum up the quantity corresponding relation between scale 6 scales and the loading force by loading counterweight.
When the manual soldering charger of hard metal tip uses, according to the blade developed width, adjust dog screw 2 positions, make ceramic pressure head 4 just in time on stellite alloy film, dog screw 2 withstands on back edge during work, plays positioning action.In blade admission face flame heat stellite alloy film brazing area.Observe the cross flow situation of solder and brazing flux, and in suitable, load.According to scale 6 scales, determine on-load pressure all the time in the scope that requires, and evenly.After the soldering completion of zone, one place, unclamp hand and move charger, the next adjacent area of soldering.
