CN2190530Y - Multifunctional iron frame - Google Patents

Abstract

The utility model makes a common iron be heated in the rated power for a period of time through a timing circuit and an AC voltage-regulating circuit in an iron frame, and after the welding temperature is reached, the circuits are switched, so that the power later consumed by the iron is only about half of the original power. Thus, the temperature of the iron is kept not rising, which achieves the purpose of constant temperature, so that the iron is suitable for welding and is not overheated. If high-temperature welding is needed, only a transfer switch needs to be dialed. In addition, for convenient welding, the iron frame is additionally provided with an elastic clamp which can clamp a weldment, a roll support for tin wires and a constant temperature tin-melting furnace besides a usual rosin box and a usual iron supporting frame.

Description

Multifunctional iron frame

The utility model is used to put the multi-functional Iron Stand of electric iron when relating to a kind of the welding.

The temperature-adjusting type Iron Stand, itself is with special electric iron, and the temperature of flatiron can be set by band switch.During work, the temperature-sensing element of flatiron inside is given testing circuit in the Iron Stand with temperature signal, and compares with the temperature of setting, and makes the temperature of solder horn reach and remains on setting value by the control circuit in the Iron Stand.This shows that the electric iron on the temperature-adjusting type Iron Stand is as common flatiron, with constant power heating, that solder horn is easy to generate is overheated, oxidation even the phenomenon burnt to death during work, the not only normal welding of influence, the service life of also having reduced common flatiron simultaneously.Compare with the constant temperature flatiron, the temperature-adjusting type Iron Stand has increased adjustment, and has the advantage of constant temperature flatiron concurrently, as not producing superheating phenomenon, has prolonged the service life of flatiron, has improved operating efficiency, has saved electric energy.But the same with the constant temperature flatiron, just because of can not be overheated, thus can't carry out high-temperature soldering, not too convenient in the use, circuit and complex structure in addition, cost is higher, and is the same with the constant temperature flatiron, is not used widely, and its function is also very single simultaneously.

The purpose of this utility model then is the problem at above-mentioned existence, provide the common flatiron of a kind of use can reach the constant temperature purpose, and fully take into account the actual conditions when welding, integrate the multi-functional electric soldering iron frame of elasticity folder, solder stick roll support, constant temperature tin melting furnace, rosin box and solder iron bracket.

The utility model technical solution:

A kind of multi-functional Iron Stand of being made up of direct current regulation circuit, electric iron, rosin box, solder iron bracket is characterized in that:

In a, the timing circuit, resistance R ₃, capacitor C ₃Series connection, its common port is received the base stage of triode T, and the colelctor electrode of T is connected to relay J and diode D ₅, resistance R ₃, relay J and diode D ₅The other end receive the positive pole of direct current regulation circuit, capacitor C ₃The other end and the grounded emitter of triode T; In the AC voltage adjusting circuit, resistance R ₄, capacitor C ₄The series connection, and with bi-directional voltage stabilizing pipe DW ₂An end form a node, DW ₂The other end control that is connected on bidirectional triode thyristor SCR extremely go up the anode of SCR and resistance R ₄The other end receive the normally opened contact J of relay J _1-2On, negative electrode and capacitor C ₄The other end receive normally-closed contact J together _1-1On.

Be respectively arranged with elasticity folder, solder stick roll support, constant temperature tin melting furnace on b, the work top.

The utility model has the advantages that: overheated, the oxidation that has overcome that the common electrical flatiron in use occurs easily, phenomenon such as burn to death, prolonged the service life of common flatiron, saved electric energy, the operating efficiency when multiple in addition function has improved welding.

Fig. 1 is a circuit diagram of the present utility model.

Fig. 2 is an outline drawing of the present utility model.

Referring now to Fig. 1, Fig. 2 the utility model is elaborated.

The circuit of Fig. 1 is made up of direct current regulation circuit, timing circuit and AC voltage adjusting circuit three parts.Resistance R ₁, capacitor C ₁, diode D ₁-D ₄, capacitor C ₂, resistance R ₂And voltage-stabiliser tube DW ₁Constitute direct current regulation circuit, give by resistance R ₃, capacitor C ₃, triode T, relay J and diode D ₅The timing circuit that constitutes provides DC voltage, and by resistance R ₄, capacitor C ₄, bi-directional voltage stabilizing pipe DW ₂, whether the AC voltage adjusting circuit work that constitutes of bidirectional triode thyristor SCR be subjected to the control of timing circuit.As socket CZ ₁Or CZ ₂On be inserted with electric iron, K switch ₁When closing, R ₃, C ₃Branch road begins charging, and T ends, and the coil no current passes through among the J, its normally-closed contact J _1-1Closure, normally opened contact J _1-2Disconnect, regulating circuit is not worked, and this moment, electric iron was heated with rated power, after flatiron fully heats after a while, and C ₃On voltage when rising to certain value, the T conducting, this moment J get electric, J _1-1Disconnect J _1-2Adhesive, regulating circuit is started working, and after this power that consumes on the electric iron has only about original half, with the no longer lifting of temperature of keeping electric iron, thereby reaches the purpose of constant temperature.Among Fig. 1, K ₃Be change-over switch, if will improve welding temperature, K need only close during normal constant temperature used ₃Get final product, disconnect K once more ₃, get back to temperature constant state again.Among Fig. 1, CT is an attaching plug, and B is a fuse, and PTC is the heated at constant temperature element of tin melting furnace, and K closes ₂Tin melting furnace can be heated to steady temperature, the fusing solder stick is so that carry out tinning.

Among Fig. 2, the switch 1 on the panel 15, fuse 2, switch 3, socket 4, change-over switch 5, socket 6, the K in the attaching plug 9 difference corresponding diagram 1 ₁, B, K ₂, CZ ₁, K ₃, CZ ₂, CT, elaboration has been done in its effect in the above.See again on the table top 14 that there is elasticity folder 13 on the left side, available clamping welded part, the left hand that can avoid so often running into is being pinched lead, and the right hand is being held flatiron, and the welded part situation of movable bad welding on the table.The back of elasticity folder is a zigzag solder stick roll support 12, and solder stick volume kink like this with using with drawing, can use continuously easily, and as now the solder stick volume is not placed on the desktop in the above, and one section of time spent intercepting earlier intercepts one section way again after using up.The right of solder stick roll support is a constant temperature tin melting furnace 11, and its heating is fast, low in energy consumption, be used for before the welding device being carried out tinning, and fixed placement, safe and reliable.The front of tin melting furnace, the right side of elasticity folder is a rosin box 7, is used to hold rosin or rosin.In addition, on table top right flank 10, be inserted with solder iron bracket 8.
