Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
See also Fig. 1, Fig. 2, Fig. 3 and Fig. 4, laser heater of the present invention comprises substrate 1, substrate 1 is provided with some radium-shine sources (not shown).
One side of substrate 1 offers groove 2, and two opposing sidewalls of groove 2 are inclined-plane 3, and another opposite flank of substrate 1 comprises two mounting faces 4 and connects the plane 5 of two mounting faces 4.Two mounting faces 4 are parallel with two inclined-planes 3 of groove 2 respectively, and the relative both sides that two mounting faces 4 are positioned at substrate 1 offer the exiting surface that some installation through holes 6, two inclined-planes 3 installing described some radium-shine sources are described some radium-shine sources.
The layout of installing through hole 6 layout type on substrate 1 and described some radium-shine sources is closely related, the layout requirements in described some radium-shine sources determines the concrete orientation of installing through hole 6, and the layout requirements of subsequent present embodiment to described some radium-shine sources describes in detail.
Described some radium-shine source layouts become two row radium-shine source groups, the radium-shine source of often arranging in the group of radium-shine source is arranged in a linear, described some radium-shine sources are arranged on the corresponding installation through hole 6 of two mounting faces 4 respectively, and the extended line in the two radium-shine sources of arranging in the groups of radium-shine source becomes a predetermined fixed angle (in the present embodiment, be 40 degree of fixed angles) staggered, the radium-shine focus making described some radium-shine sources is evenly on the continual straight line meeting at into 40 degree of fixed angles.Thus, laser heater of the present invention can realize continuing workpiece, homogeneous heating, thus product coating after thermal treatment coating is even, and production efficiency is high.
The fixed angle of 40 ° is best suited for the angle of heated parts, and the test that also have passed some amount in an experiment proves.The fixed angles of 40 ° determines in conjunction with the size of substrate 1, can follow the dimensional change of substrate 1 and suitably change.But, the size of general substrate 1 is determined by the bracing frame on coating equipment, scope can be transferred little, which ensure that radium-shine unit is to by the distance between the workpiece that heats, if from too close to, during heating, the too high meeting of temperature burns out the screw thread of workpiece, if the distance is too far, the powder be sprayed on workpiece can not melt completely, does not reach excellent coating effects, and the determined distance of size of such fixed angle and substrate 1 can make plated film reach most desired effect.When giving workpiece plated film, Partial coatings only to workpiece screw thread, so the point of heating mainly concentrates on the place of pulverized powder, i.e. the intersection point of double radium-shine unit transmitting, workpiece itself is metallic substance, utilizes the thermal conduction of self just powder uniform melt can be wrapped up in and is attached on workpiece.
In addition, facts have proved, adopt single radium-shine source can not by all radium-shine focuses evenly continual straight line meeting at into described predetermined fixed angle, therefore limitless close-packed arrays cannot realize the beneficial effect of this case, also have reason to be exactly between radium-shine unit, leave the heat radiation that certain interval is conducive to radium-shine unit simultaneously, be unlikely to the smooth temperature of single close-packed arrays heat radiation too high and make substrate 1 is fixed the screw thread fusing of radium-shine unit, once certain radium-shine unit breaks down or can change, substrate 1 can repeatedly be reused.Reduce risk, reduce cost, also can not quit work because heating unit goes wrong simultaneously.
Two mounting faces 4 can with plane 5 in step-like, only otherwise the radium-shine focus affecting described some radium-shine sources evenly on the continual straight line meeting at into 40 degree of fixed angles.Preferably, two mounting face 4 opposite planar 5 symmetrically structure, can make the intensity of two row radium-shine source groups suitable like this.
Laser heater also can add the cooling system for cooling described laser heater, and cooling system can make temperature instantaneous cooling to 0 DEG C, workpiece is continued, homogeneous heating.Because radium-shine source temperature in heat-processed is very high, can make substrate 1 to be fixed radium-shine first screw thread fusing, there is the risk burning out workpiece, even can burn out radium-shine source, in order to ensure that laser heater is not burned, heating for some time must stop heating cooling for a long time halfway, and speed is slow, efficiency is low.After adding refrigerating unit; instantaneously cooled 0 DEG C of laser heater temperature can be made; as long as arrange cooling system to cool laser heater according to some cycles; not only ensure that the safety of equipment; and can for a long time, continue to workpiece heat; improve working efficiency, protect the safety of workpiece, extend the work-ing life of laser heater.Described cooling system can adopt a variety of, as adopted the mode of cooling fluid, or adopts flowing water route type of cooling etc., as long as can be convenient to realize the cooling of described laser heater.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
