Description

A kind of special-purpose aluminium soldering case

The utility model relates to a kind of soldering case, the special-purpose soldering case of particularly a kind of aluminium soldering, and it is applicable to the high temperature solder brazing of industrial, civilian, military aluminum products such as various aluminium radiators, air-conditioner, condenser, evaporimeter, warm-air drier.

Aluminium product of the prior art soldering mainly contains two kinds of salt bath dip brazing and vacuum furnace brazings.The salt bath dip brazing owing to its a large amount of residual saline solution pollution on the environment and residual saline solution after product inside is adhered to extremely difficulty clean up and cause the product corrosion, so this method is progressively being eliminated all over the world; A large amount of what adopt is the vacuum furnace brazing by various countries now, its vacuum drying oven structure as shown in Figure 1, this vacuum drying oven mainly by electric-control system 1 ', heat exchanger 2 ', heating clamber 3 ', body of heater 4 ', vacuum pipe 5 ', vacuum unit 6 ', blower fan 7 ' and calandria 8 ' form, during use, with aluminium workpiece 9 ' put into calandria 8 ', the limit heating edge vacuumizes, make vacuum drying oven when the brazed aluminum product, can in stove, set up the region of no pressure, aluminium product surface oxide-film can't be generated, thereby make product obtain satisfied soldering effect.Although the soldering effect of this vacuum drying oven is better, but when reality is used, still there is following major defect in it: this stove price is very expensive, power consumption in production run, consumption gas, water consumption are all very big, equipment maintenance cost is also high at ordinary times, so with the valuable product (price as aluminium radiator is higher than copper heat transmission gas price more than a times) of vacuum drying oven production, so the aluminium soldering product is acknowledged as the commodity of high investment, low output.

The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and provide a kind of reasonable in design, operating cost low, be adapted at a kind of special-purpose aluminium soldering case that carries out the solder brazing of aluminium product high temperature in the cabinet-type electric furnace commonly used.

The purpose that the utility model proposed can be achieved through the following technical solutions: the design feature of this aluminium soldering case is: it mainly is made up of casing, case lid, air inlet pipe, gas averaging board and temp measuring system, air inlet pipe is positioned at the bottom of casing, gas averaging board is positioned at the top of air inlet pipe, and is densely covered with aperture on this gas averaging board.

Description of drawings is as follows:

Fig. 1 is the structural representation of vacuum drying oven in the prior art.

Fig. 2 is a structural representation of the present utility model.

Fig. 3 is position and the user mode schematic diagram of the utility model in batch-type furnace.

Following the utility model will be in conjunction with the accompanying drawings, and be described in further detail by embodiment.

Referring to Fig. 2, the utility model mainly is made up of casing 10, case lid 11, air inlet pipe 14, gas averaging board 12 and temp measuring system II, and casing 10 is formed by corrosion resistant plate weldering system, and air inlet pipe 14 is positioned at the bottom of casing 10, one end of this air inlet pipe 14 is in case, and the other end leads to outside the stove always; Gas averaging board 12 is positioned at the top of air inlet pipe 14, just forms an interlayer like this between gas averaging board 12 and air inlet pipe 14, and this interlayer is equal air chamber 13; Be densely covered with the aperture 12-1 of countless 2 millimeter on gas averaging board 12, protective gas can evenly overflow from this aperture 12-1, guarantees that distribution of gas is even in the whole soldering case I; Temp measuring system II comprises thermometer hole 11 at the bottom of the case, thermometric air leakage hole 17 and thermometric cooling venthole 18, and thermometer hole 11 is positioned at the bottom of casing 10 at the bottom of the case, and it is used to monitor the temperature of soldering case bottom in brazing process; Thermometric air leakage hole 17 and thermometric cooling venthole 18 all are located on the case lid 19, the design of thermometric air leakage hole 17 has two effects, the one, the thermocouple that thermometric is used inserts soldering case I through this hole center, understand the temperature at casing 10 centers in the brazing process, the 2nd, the gas of taking away oxygen molecule can overflow casing thus, casing 10 interior gases are constantly flowed, keep pure, promptly keep the vacuum in the casing 10; The design of thermometric cooling venthole 18 also has two effects, the one, by the thermocouple temperature on casing 10 tops as can be known at any time, the 2nd, after soldering is finished, the refrigerating gas that charges in the casing 10 is taken away heat rapidly through this pipe, to guarantee the manufacturability of soldering cooling; For making brazing product guarantee to be under the tight protection of gas, the upper end and the design of case lid 19 cooperation places of casing 10 sand seal groove 15 is arranged, gas can too much not overflowed in this junction; On case lid 19, also be provided with atmosphere thief hole 16,, adjust the degree of purity of gas in the casing 10, guarantee the quality of soldering so that when soldering, extract the atmospheric analysis atmospheric dew point.

Referring to Fig. 3, this stove can be changed a little with the cabinet-type electric furnace of routine and make, mainly transmitting guide rail 23, control system 24 and gas protection system 25 by gantry crane system 20, box-type furnace 21, electric heating body 22, stokehold forms, during use, as long as soldering case I is pushed the high temperature solder brazing that can carry out the aluminium product in the stove because when using with soldering case I as the region of no pressure; 9 are aluminium workpiece to be brazed.

The utility model compared with prior art has the following advantages: 1, reasonable in design, make simply, Be easy to promote, one-time investment reduced greatly: since when using with the soldering case as the region of no pressure, so right The performance requirement of stove reduces greatly, as long as can use with general cabinet-type electric furnace; 2, this structural design makes life Produce operating cost and greatly reduce, product profit is improved; 3, this structure also makes production efficiency greatly improve, and is Substitute the best product of vacuum drying oven.
