Description
Technical field
The present invention relates to a kind of tin soldering equipment, more particularly to a kind of tin soldering equipment of hand-held.
Background technology
Welding is the material of welded piece(Of the same race or xenogenesis), by heat or pressurization or both be used in combination, and use or not
With packing material, the material of workpiece is reached interatomic combination and form the technical process of permanent connection.Soldering is electrical equipment
The cable circuit commonly used in industry is connected mode, and people often carry out soldering operation with electric iron or soldering gun.
Electric iron is to use most common tin soldering tool, needs to take electric iron on the other hand in operation, proficiency Na Xisi,
Soldering operation is inconvenient, and is also easy to produce potential safety hazard, and such as burnt hand can also cause the waste of tin silk.
One of common form of hand feed is the index(ing) feed of propelling pencil, and the feeding mode utilizes gravity and inertia
Principle realizes feeding to pencil-lead, but this principle is not suitable for the feeding of tin silk, and Xi Si is pliable, rub compared with pencil-lead
Wipe coefficient greatly, the mode fed using gravity is not high come the feeding reliability for realizing tin silk.
Publication No. 201552358U utility model discloses a kind of improved manual soldering gun, and it includes rifle shell and pulled
It is provided with machine, the rifle shell in the steel pipe through rifle shell right-hand member, steel pipe and is provided with heat generating core, heat generating core connection solder horn,
Tin-tube is provided with out below the rifle shell, goes out tin-tube left end and is provided with into tin-tube, trigger top is provided with contact roller, and contact roller is located at
Enter tin-tube right-hand member, it is described to go out tin-tube and to enter between tin-tube to be provided with tin-guiding tube.This improved manual soldering gun one-hand operation, is used
It is convenient, even if but add the tin-guiding tube of bell shape, the position that tin silk slightly deformed or entered tin-guiding tube is forbidden, tin silk
Will be stuck, result in blockage.
A kind of tin soldering equipment of Publication No. 103121137A disclosure of the invention, including heat-resisting body, the heat-resisting body
Heating wire is inside provided with, the heat-resistant tube is provided with thermal insulation layer in vitro, and the affiliated heat-resisting body one end open other end sets sealing
Soft set, the heat-resisting body is divided into body top and body bottom, and the body top and the body bottom use screw thread
Connection.This tin soldering equipment can be welded in the place of narrow space, simple in construction, but be by tin during its use
Silk is added to heat-resisting body, is melted into tin soldering liquid by electrothermal filament smelting, then tin soldering liquid is extruded into resistance to heat pipe by extruding soft cover
To carry out soldering operation, the discharge rate of its tin liquor can be controlled, but the consumption of of tin silk itself is that the amount of feeding is difficult to control,
Waste is easily caused, and tin liquor unnecessary in body after use is not disposable.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of hand-held tin soldering equipment, and the device can control tin manually
