Abstract
The utility model relates to a cooling maintenance device for a reinforcing bar surface coating machine. The device comprises a front part maintenance section and a rear part cooling section; a water tank is arranged at the lower part of a roller of the maintenance section; a water flow pipeline is arranged on one side of the roller; a water flow spray nozzle is arranged on the water flow pipeline and in the position directed at a groove on the roller; and an atomization sprinkling device is arranged on the cooling section. The utility model can improve the quality of the surface coating layer of a reinforcing bar and the yield rate by adopting a reasonable maintenance cooling manner.
Description
Technical field
The utility model relates to reinforcing bar production equipment field, relates in particular to the coating machine of reinforcing steel bar surface coating.
Background technology
For the high stationarity that adapts to high-speed railway, high-durability, high-comfort requirement, need to adopt and the no slag track of the few maintenance of development.Because China Railway High-speed signal transmission is to be undertaken by rail, track slab pavement on the line, the electromagnetic induction that inner bar-mat reinforcement produces can produce bigger influence to the signal transmission distance of rail.Therefore, patent 200620032895.8 discloses a kind of insulating reinforcing steel bars, scribbles insulating coating by the precast reinforced surface at track, generally applies epoxy resin; Thereby the track plate does not form the loop to the reinforcing bar intersection in length and breadth, does not produce electromagnetic induction, and the track plate can not exert an influence thus to the signal transmission distance of rail.In addition, the reinforcing bar of this surface-coated not only can be applied in the pre-track plate of high-speed railway, and harbour, boats and ships etc. have in the environment for use of corrosion-resistant requirement but also for example can be widely used in.
For the production of above-mentioned insulating reinforcing steel bars, can adopt the reinforcing steel bar surface coating coating machine of quantity-produced streamline form at present.Many reinforcing bars (being generally 8 to 12) are placed side by side on the roller-way that streamline is provided with, reinforcing bar carries out surface treatment at wheel abrator cabinet successively, heats in the heating in medium frequency stove, carries out surface-coated at spray booth, cool off at spray chamber then, carry out blanking in the blanking section at last.Behind reinforcing bar process spray booth, the temperature of reinforcing bar is very high, and the rebar surface coat adhesion of just having adhered to and material are also very weak, if the surface of the direct contacting metal running roller of reinforcing bar this moment, can pass to running roller to heat, one section working time rear roll surface temperature also can be very high, and not only the running roller life-span can shorten, and running roller can damage or the coat of adhesion transfer reinforcing bar.At present generally be to adopt the directly type of cooling of water spray cooling, but because reinforcing bar interior metal layer is different with the material of external rings epoxy resins coat, shrinks inconsistent, directly fast water-cooled can cause the coat generation wrinkling, bad phenomenon such as peel off, unstable product quality, yield is low.Therefore, after spraying coat being carried out maintenance and suitable cooling, is the important process of producing insulating reinforcing steel bars.
The utility model content
Cooling section technology was unreasonable during the applicant produced at above-mentioned existing insulating reinforcing steel bars, unstable product quality, and shortcoming such as yield is low provides a kind of technology reasonable, the maintenance cooling device of the reinforcing steel bar surface coating coating machine of the high yield of high-quality.
The technical scheme that the utility model adopted is as follows:
The cooling curing means of reinforcing steel bar surface coating coating machine, comprise anterior maintenance section and rear portion cooling section that series connection is provided with, running roller bottom in the maintenance section is provided with water tank, side at running roller is provided with water pipe, in the groove location of aiming on the running roller on the water pipe water jet is set, atomizing sprayer is set at cooling section.
The utility model can improve the quality of rebar surface coat by the rational maintenance type of cooling is set, and improves yields.

Fig. 4 is the cutaway view of A-A face among Fig. 1.(reinforcing bar and current are the duty signal among the figure)
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, cooling curing means described in the utility model comprises the anterior curing means 1 and rear portion cooling device 2 that series connection is provided with.As Fig. 2, shown in Figure 3, the structure of curing means 1 is for being provided with water tank 3 in each running roller 6 bottom of master roller maintenance section, about 1/3 part in running roller 6 bottoms immerses the water surface of water tank 3, the side of while on the top of water tank 3 is provided with water pipe 4, at the reinforcing bar groove of aiming on the running roller 6 on the water pipe 48 water jet 5 is set.As shown in Figure 4, the structure of cooling device 2 is carried out atomizing spray for many row's high pressure nozzles 9 are set to the reinforcing bar coat above the master roller cooling section; Return water tank 10 is set below the master roller cooling section.
The utility model is provided with water tank 3 in running roller 6 bottoms of maintenance section 1, and auxiliary water spray the in side of the reinforcing bar groove of running roller 6 being adopted water jet 5, be not that reinforcing bar is directly sprayed water, can well maintenance just through after having dusted, the rebar surface coat that adhesion and material are also very weak; The utility model arrives the running roller groove surfaces with water flow jet; by the running roller rotation water is brought between the groove surfaces and reinforcing bar coat of running roller 6; under action of high temperature, formed very thin vapor film; this vapor film has well completely cut off the running roller groove surfaces and has contacted with the direct of reinforcing bar coat; thereby avoided the damage of weak rebar surface coat; to the running roller cooling, protect running roller simultaneously.After a plurality of maintenance running rollers of process, the surface coating layer of reinforcing bar solidifies gradually, at this moment, see Fig. 4, enter cooling device 2 cooling gradually under the atomizing spray of many row's high pressure nozzles 9, atomizing spray can guarantee that reinforcing bar obtains evenly good cooling, makes inner reinforcing bar and external resin layer synchronous, prevents the mass defect that quick water-cooled causes in the prior art.
More than describing is to explanation of the present utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of spirit of the present utility model, the utility model can be done any type of modification.
