Description
Technical field
The present invention relates to a kind of heating frock, particularly relate to one and be applicable to gas and carry powder roll laser cladding preheating frock.
Background technology
Original gravity powder feeding roll laser cladding preheating frock, relies on gravity powder feeding, substantially can meet general processing request.But along with the continuous progress of technology, the progressively introducing of new technology, laser processing also progresses into many new fields, especially gas carries the introducing of automatic powder feeding system, original gravity powder feeding roll laser cladding preheating frock can not meet present processing request, and mainly the following aspects has obvious defect.
1. affect the shaping surface quality of powder, the hot gas flow produced due to frock and powder feeding air-flow interact and affect the conveying of powder to molten bath, cause laser cladding layer surface irregularity not reach processing requirement.
2. in the course of processing, controllability is poor, due to the opening of original frock above body of heater and also opening very narrow, in cladding process, operator are difficult to effectively observe, and whole cladding process can not get effective control.
3. do not have powder recovering device, because gas carries, the single powder using efficiency of powder is lower only has about 30 percent, and the shortage of powder recovering device is bound to cost of idleness.
Summary of the invention
Object of the present invention is just the problems referred to above solving prior art existence, provides one to be applicable to gas and carries powder roll laser cladding preheating frock.The temperature of roll can be risen to 400 degrees Celsius by this frock within half hour, is topmostly that of avoiding the impact of hot gas flow on powder feeding, and the Forming Quality of cladding layer is well controlled, and it is simple to operate, easy accessibility, maintenance are easily quick.
The technical scheme that the present invention provides is: this gas carries powder roll laser cladding preheating frock, include the burner hearth of furnace body frame and the stainless steel plate making be welded by angle steel, be characterized in that the body of heater of frock is up and down to the lateral openings structure of dividing, renovating of band folding is provided with at the lateral openings place of body of heater, the two ends of renovating are provided with suspension ring, furnace lining has asbestos thermal insulation layer and uralite, thermopair socket is provided with in the side wall upper part of body of heater, be provided with powder dish socket at the sidewall bottom of body of heater, in body of heater, be also provided with three 8kw/220v armouring heating pieces.
Compared with prior art, the invention has the beneficial effects as follows.
1. improve the Forming Quality of cladding layer.
Because the air-flow at lateral openings place is relatively mild, and when carrying out laser melting coating herein powder mouth and upstream angle more greatly, the impact of upstream on powder feeding air-flow obviously reduces, and clad layer surface forming quality is well controlled.
2. significantly improve the controllability of cladding process.
It is convenient that side direction carries out laser processing convenient operation person operational observations, and the controllability of whole like this cladding process greatly strengthens.
3. improve the utilization ratio of powder.
Powder dish socket be arranged so that powder can obtain reclaiming in time the oxidation of avoiding powder and pollute the utilization ratio improving powder.
4. easy for installation.
Furnace body frame is welded by 40 angle steel, the stainless steel plate that burner hearth material selection 3mm is thick, and the light and asbestos of high insulating effect selected by lagging material, are provided with the suspension ring of two M12 on the top of frock, the light lifting of frock and install all very convenient.
Accompanying drawing explanation
Fig. 1 is preheating tool structure schematic diagram.
Fig. 2 is the side-view of Fig. 1.
Mark in figure: 1. body of heater, 2. renovate, 3. folding, 4. suspension ring, 5. thermopair socket, 6. powder dish socket, 7. asbestos thermal insulation layer, 8. uralite, 9. armouring heating piece, 10. go up lower box and connect pilot hole.
Embodiment
As as described in Fig. 1 ~ Fig. 2, this gas carries powder roll laser cladding preheating frock, include the burner hearth of the body of heater 1 and stainless steel plate making be welded by angle steel, wherein the body of heater 1 of frock is up and down to the lateral openings structure of dividing, namely change into up and down to the lateral openings structure of dividing by the left and right of original body of heater 1 to point upper end open structure, such benefit be first body of heater 1 up and down to point structure can play better heat insulation effect, secondly more importantly the air-flow at the lateral openings place of body of heater 1 is milder, and the angle of powder mouth and upstream is larger when carrying out laser melting coating herein, the impact of upstream on powder feeding air-flow obviously reduces, clad layer surface forming quality is well controlled.And carry out laser processing convenient operation person operational observations conveniently in side direction, the controllability of whole like this cladding process greatly strengthens.What be provided with the folding 3 of three bands at the lateral openings place of body of heater 1 renovates 2, all renovating all can be closed during heating, corresponding one to two can be opened as required when preheating temperature carries out laser melting coating renovate when reaching, so both meet the needs of processing, turn avoid a large amount of losses of heat.The two ends of renovating are provided with two M12 suspension ring 4, light lifting and install all very convenient, gently the asbestos thermal insulation layer 7 of high insulating effect and uralite 8 is lined with in body of heater 1, thermopair socket 5 is provided with in the side wall upper part of body of heater 1, a powder dish socket 6 is provided with in the lower sidewall of body of heater 1, inserted from it by powder dish during cladding, powder dish is extracted out by processing interval, and such powder can reclaim the oxidation avoiding powder and the utilization ratio polluting raising powder in time.The framework of body of heater 1 is welded by 40 angle steel; the stainless steel plate that burner hearth material selection 3mm is thick; three 8kw/220v armouring heating pieces 9 are also provided with in body of heater 1; this armouring heating piece 9 not only heats is good but also have the protection of ceramics to be not easily short-circuited fault due to resistance wire, and the maintainability of frock is greatly improved.The subsidiary thermopair of temperature controller, inserts the thermopair socket 5 of thermopair from body of heater 1 side wall upper part when heating, can Measurement accuracy in-furnace temperature, and on temperature controller in addition Power Conditioning Unit can adjust output rating in global extent.
