Abstract
The utility model relates to an automatic giving-tin thermostatic electrical iron, which is characterized in that the electric iron is provided with a temperature control device. The working temperature of the soldering iron is controlled by a temperature sensor and a temperature control switch and commercial power can be directly fed in a heating mechanism to realize temperature control.
Description
The present invention relates to a kind ofly directly send the tin constant temperature electric iron automatically with the mains supply heating.
Existing pistol type electric iron only comprises and send tin mechanism, welding mechanism and heating arrangements, and do not have temperature control mechanism, and temperature can not accurately be controlled, and heat is not fully utilized, solder horn (20) working position easily be scorched to death (Non-Dewetting).Though what have has a temperature control mechanism, must be with mains voltage through the transformer coupled soldering gun of delivering to, with low voltage heating iron head (20), so complex structure.All there is the shortcoming of insulating properties difference under the high temperature in the electric iron of above-mentioned two kinds of structures.
The objective of the invention is to design a kind of transformer step-down that need not, can be directly civil power feed-in heating arrangements be realized temperature control, again with original send that tin, heating, constant temperature and welding four parts are integrated in one send the tin constant temperature electric iron automatically.
Pistol type send the structure and the operation principle of tin constant temperature electric iron (see figure 1) to be automatically: when civil power imports electric iron into by lead (14), (be the heat temperature raising stage this moment through temperature detect switch (TDS) (4), switch is in connects closure state) heating core (heating arrangements) (1) is generated heat, the electric soldering bit (20) that inserts in its chamber also obtains heating simultaneously, just can work when deciding operating temperature when reaching to give, at this moment give and enclosing earlier around the solder stick of rolling up on the tin dish assembly (8) (7), pass space between clamping frame parts (10) and the rifle bolt feeding (16) through guide pipe (9), pass through feed conduit (18) again.Pull the people under the situation of plate machine, solder stick (7) is beaten on the working position of solder horn (20), the fusing back is welding work pieces directly.
Give and decide operating temperature by temperature control sensor (21) and temperature detect switch (TDS) (4) control, the temperature detect switch (TDS) assembly pushes against solder horn (20) afterbody by spring (5).In Fig. 2, iron-nickel alloy temperature control sensor (21) directly uses mechanical means and solder horn (20) to combine, temperature control sensor (21) is the temperature of perception solder horn (20) directly, utilize the composition proportion difference of iron-nickel alloy, temperature control sensor (21) can obtain the characteristics of the different Curie point of height, sets solder horn (20) operating temperature of certain value.During work when temperature surpasses this and sets Curie-point temperature value, the iron-nickel alloy body just loses ferromagnetic rerum natura, the former magnet steel (22) that is held by iron-nickel alloy temperature control sensor (21), then attracted by soft iron (23), because soft iron (23) is fixed on temperature detect switch (TDS) (4) housing (13), magnet steel (22) is connected an end of connecting rod (24), and the other end of connecting rod (24) is equipped with temperature detect switch (TDS) (4) movable contact.Connecting rod (24) slides in the endoporus of soft iron (23), because magnet steel (22) is inhaled to soft iron (23), move after then making connecting rod (24), make the sound contact separation in the sound contact sets (25) in the temperature detect switch (TDS) (4), cut off incoming power, stop heating, heating core (1) and solder horn (20) temperature descend immediately, when dropping to when being lower than this iron-nickel alloy Curie-point temperature, iron-nickel alloy temperature control sensor (21) has recovered ferromagnetic rerum natura again, its powerful attraction makes magnet steel (22) break away from soft iron (23), again with solder horn (20) and temperature control sensor (21) adhesive, sound contact sets (25) engages simultaneously, power supply is connected once more, heating core (1) begins heating iron head (20) again, goes round and begins again, and solder horn (20) working position temperature is controlled in all the time gives fixed temperature spot (in the little temperature range).During welding work pieces, the heat that consumes during owing to workpiece heat radiation and fusing scolding tin descends the temperature of solder horn (20) working position, occurs above-mentioned cyclic process equally.
The present invention adopts plasma spraying method in order to improve heating core (1) electrical insulation capability at high temperature, coats Al at heating core (1) matrix surface
2O
3Coating (26).Because aluminium oxide purity height, spraying back coating (26) is a kind of aluminium oxide thin layer with micropore, under the high temperature in the micropore moisture be discharged from, so the electrical insulation capability under the high temperature is good, this has just remedied insulating materials such as the general mica sheet shortcoming that descends of electrical insulation capability at high temperature.As coating (26) materials A l
2O
3Add in the powder and contain 19.5% SiO
2Tetraethoxysilance solution after carry out powder process, can make part A l
2O
3One deck SiO is wrapped in the powder outside
2Thereby, further improved the adhesion of coating (26) and the performance of opposing suddenly cold and hot after the spraying.The topped heating core of coating (26) (1) matrix, make the metal electric heating silk effectively with the insulation of internal layer and end plane metal thing, when the metal electric heating silk, still use mica sheet (19) etc. as layer insulation.Such heating core (1) high pressure resistant test of moment when cold conditions (room temperature) can reach 2700V～3000V and not puncture; Hot insulation impedance reaches 50M Ω (by GB4706.1-84 " the safety general requirement of family expenses and similar applications electrical equipment " test); Leakage current only 4.84 * 10 when operating temperature is 330 ℃～370 ℃
-3MA.
