Abstract
The invention relates to an airborne powder sending roller laser cladding preheating tool. The tool comprises a furnace body frame formed through welding angle steel and a hearth made through using a stainless steel board. The tool is characterized in that the furnace body of the tool has a top-and-bottom halving lateral opening structure, the lateral opening of the furnace body is provided with a turnable cover having folders, two ends of the turnable cover are respectively provided with a suspension ring, the inner liner of the furnace body has an asbestos thermal insulation layer and a cement asbestos board, the upper portion of the sidewall of the furnace body is provided with a thermocouple jack, the bottom of the sidewall of the furnace body is provided with a powder disc jack, and three 8kw/220v armored heating boards are arranged in the furnace body. The tool allows the temperature of the roller to rise to 400DEG C within 0.5h, avoids the influences of hot airflow to powder sending, makes the molding quality of a cladding layer be well controlled, and has the characteristics of simple operation, convenient dismounting and mounting, and easy and fast maintenance.
Description
Technical field
The present invention relates to a kind of heating frock, particularly relate to a kind of gas that is applicable to and carry powder roll laser cladding preheating frock.
Background technology
Original gravity powder feeding roll laser cladding preheating frock relies on the gravity powder feeding, can satisfy general processing request basically.But along with continuous advancement in technology, the progressively introducing of new technology, laser processing also progresses into many new fields, especially gas carries the introducing of powder mode, original gravity powder feeding roll laser cladding preheating frock can not satisfy present processing request, mainly is that the following aspects has obvious defects.
1. influence the shaping surface quality of powder, influence powder to the conveying in molten bath because the hot gas flow that frock produces and powder feeding air-flow interact, cause the laser cladding layer surface irregularity not reach processing requirement.
2. controllability is poor in the course of processing and since the opening of original frock above body of heater and also opening very narrow, operator are difficult to effectively observe in the cladding process, whole cladding process can not get effective control.
3. do not have powder recovering device, have only about 30 percent because the single powder using efficiency that gas carries powder is low, the shortage of the powder recovering device cost of idleness that is bound to.
Summary of the invention
Purpose of the present invention just is to solve the problems referred to above that prior art exists, and provides a kind of gas that is applicable to carry powder roll laser cladding preheating frock.This frock can be in half hour rises to 400 degrees centigrade with the temperature of roll, has most importantly avoided the influence of hot gas flow to powder feeding, and the Forming Quality of cladding layer is well controlled, and it is simple to operate, easy accessibility, maintenance are quick easily.
The technical scheme that the present invention provides is: this gas carries powder roll laser cladding preheating frock, include the burner hearth that the furnace body frame that is welded by angle steel and stainless steel plate are made, the body of heater that is characterized in frock is the lateral openings structure to dividing up and down, be provided with renovating of band folding at the lateral openings place of body of heater, be provided with suspension ring at the two ends of renovating, furnace lining has asbestos thermal insulation layer and uralite, be provided with the thermopair socket on side wall of furnace top, be provided with powder dish socket in the side wall of furnace bottom, also be provided with three 8kw/220v armouring heating pieces in the body of heater.
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 milder, and the angle of powder mouth and upstream is bigger when carrying out laser melting coating herein, and upstream obviously reduces the influence of powder feeding air-flow, and cladding layer shaping surface quality is well controlled.
2. obviously improve the controllability of cladding process.
Side direction is carried out laser processing, and to be convenient to operator's operational observations convenient, and the controllability of whole like this cladding process greatly strengthens.
3. improve the utilization ratio of powder.
Being arranged so that oxidation that powder can in time be reclaimed avoids powder and polluting the utilization ratio that improves powder of powder dish socket.
4. easy for installation.
Furnace body frame is welded by 40 angle steel, and the stainless steel plate that burner hearth material selection 3mm is thick, lagging material are selected for use light and the asbestos of high insulating effect, is provided with the suspension ring of two M12 on the top of frock, and the light lifting of frock and installation are all very convenient.

Fig. 1 is preheating tool structure synoptic diagram.
Fig. 2 is the side-view of Fig. 1.
Mark among the 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. the armouring heating piece is 10. gone up lower box and is connected pilot hole.
Embodiment
As described in Fig. 1～Fig. 2, this gas carries powder roll laser cladding preheating frock, include the burner hearth that the body of heater 1 that is welded by angle steel and stainless steel plate are made, wherein the body of heater 1 of frock is the lateral openings structure to dividing up and down, namely by about original body of heater 1 minute upper end open structure being changed into the lateral openings structure to dividing up and down, what such benefit was body of heater 1 at first can play better heat insulation effect to the structure of dividing up and down, secondly main is that the air-flow at lateral openings place of body of heater 1 is milder, and the angle of powder mouth and upstream is bigger when carrying out laser melting coating herein, upstream obviously reduces the influence of powder feeding air-flow, and cladding layer shaping surface quality is well controlled.And carrying out laser processing in side direction, to be convenient to operator's operational observations convenient, and 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 can be renovated all during heating and close, when reaching preheating temperature and carry out laser melting coating, can open corresponding one to two as required and renovate, so both satisfy the needs of processing, avoid a large amount of losses of heat again.Be provided with two M12 suspension ring 4 at the two ends of renovating, light lifting and installation are all very convenient, be lined with light in the body of heater 1 and asbestos thermal insulation layer 7 and the uralite 8 of high insulating effect, side wall upper part at body of heater 1 is provided with thermopair socket 5, lower sidewall at body of heater 1 is provided with a powder dish socket 6, during cladding the powder dish is inserted from it, processing is intermittently extracted the powder dish out, and powder can in time reclaim the oxidation of avoiding powder and pollute the utilization ratio that improves powder like this.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; also be provided with three 8kw/220v armouring heating pieces 9 in the body of heater 1; this armouring heating piece 9 not only heats good and also since resistance wire have the protection of ceramics to be difficult for the fault that is short-circuited, make the maintainability of frock greatly improve.Temperature controller attaches an electroheat pair, when heating the thermopair socket 5 of thermopair from body of heater 1 side wall upper part is inserted, and can accurately measure temperature in the stove, and also have Power Conditioning Unit can adjust output rating on the temperature controller in global extent.
