Description

Welding wire self-carrying electric iron

The utility model relates to a kind of improvement of electric iron, and specifically a kind of welding wire self-carrying electric iron is applicable to the welding of electric elements, electric appliance circuits.

At present, in the welding of electric elements, electric appliance circuits, soldering appliance commonly used is an electric iron, and welding medium is the tin bar welding wire.Electric iron is made of shell, handgrip, solder horn, heating, during use, heating is connected the power supply heating, and, make the solder horn heating by the heat conduction, again the tin bar welding wire is contacted the solder horn end, make the tin bar wire melting, contain the solder horn end, aim at the welding position again and weld, this kind flatiron separates with electric iron owing to the tin bar welding wire, the inconvenience that operates especially can not be welded with one-handed performance, and welding efficiency is low, when hanging operation, this shortcoming is more outstanding.

The purpose of this utility model be to provide a kind of easy to use, flexible operation, welding efficiency height, can a hand operated welding wire self-carrying electric iron.

The utility model is achieved in that this welding wire self-carrying electric iron is made of shell, handgrip, solder horn, electric iron, tin bar welding wire, its tin bar welding wire rolls on around the line of housing rear end, the welding wire conduit is passed in tin bar welding wire outer end, by the tractive of welding wire conveying device, touch to solder horn from the front port of welding wire conduit.This welding wire self-carrying electric iron also can be implemented by following measure: its welding wire conveying device is by driving gear, idle wheel, driven gear, the rubber pinch roller, trigger, back-moving spring, the welding wire conduit constitutes, the tin bar welding wire is pressed on the driven gear with the rubber pinch roller, the tooth bar of trigger and driving gear engagement, the tooth bar rear end of plate machine is pressed on the back-moving spring, when pulling trigger backward, driving gear rotates, pass through idle wheel, the drive driven gear rotates, thereby the tin bar welding wire is fed forward, touch to solder horn, when unclamping trigger, because the trigger tooth bar has compressed back-moving spring, so back-moving spring makes trigger return to the origin-location again, the trigger tooth bar is contained in the guide groove, and preventing trigger tooth bar offset direction, the inner chamber that the welding wire conduit passes shell is fixed on the end of shell, the front port of its welding wire conduit is near solder horn, the inner end mouth is near driven gear and rubber pinch roller, and rear port rolls near line, and the tin bar welding wire touches to solder horn at the front end oral area of welding wire conduit forward by the welding wire conduit; For preventing the driving gear reversing, also be provided with ejector pin at the driving gear rear portion usually; Tin bar welding wire mode of movement of the present utility model also can adopt small-sized motor traction to carry, and the tin bar welding wire passes in the welding wire conduit, is fed forward by traction wheel; Electrical heating elements in the electric iron can be established two grades, and by temperature regulating switch control, temperature regulating switch is fixed on the outside of housing, with easy to operate.

The utility model has the advantages that: compare with the electric iron of present use, realized the integrated of flatiron and welding wire, easy to operate, use flexibly, can operate by one hand, improved welding efficiency.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Accompanying drawing 1 is looked schematic diagram for the utility model master.

Accompanying drawing 2 is the utility model cross-sectional schematic.

Make the utility model with reference to accompanying drawing 1,2.This welding wire self-carrying electric iron is by shell 1, handgrip 2, solder horn 3, electric iron 4, tin bar welding wire 5 constitutes, its shell 1 usefulness iron sheet is made, also available plastic injection-moulded, can make the rifle formula, electric iron 4 is housed in the gun barrel of shell 1, solder horn 3 stretches out housing 1 muzzle outside, handgrip 2 is located at small of the stock position, be provided with line at the gun platform position and roll 6, welding wire conveying device 7 is established in the gun barrel bottom, and tin bar welding wire 5 rolls on 6 around line, and the welding wire conduit 17 in the gun barrel is passed in tin bar welding wire 5 outer ends, by the tractive of welding wire conveying device 7, touch tip to solder horn 3 from the front port of welding wire conduit 17.Welding wire conveying device 7 is by driving gear 8, idle wheel 9, driven gear 10, rubber pinch roller 11, trigger 12, back-moving spring 13, guide groove 14, welding wire conduit 17 constitutes, the translation tooth bar of trigger 12 and driving gear 8 engagements, by idle wheel 9, driven gear 10 is rotated, rubber pinch roller 11 is pressed on the driven gear 10, and tin bar welding wire 5 is pressed on the driven gear 10, welding wire conduit 17 is fixed on the muzzle and the gun platform position of shell 1, the front port of welding wire conduit 17 is near solder horn 3, the inner end mouth is near driven gear 10 and rubber pinch roller 11, rear port rolls 6 near line, tin bar welding wire 5 passes welding wire conduit 17, when driven gear 10 rotates, promoting tin bar welding wire 5 is fed forward, when pulling trigger 12, the tooth bar of trigger 12 has compressed back-moving spring 13, so when unclamping trigger 12, back-moving spring 13 promotes trigger 12 and moves forward, and returns to the origin-location, for preventing plate machine 12 offset direction when plate is moving, the tooth bar of plate machine 12 is contained in the guide groove 14, for preventing driving gear 8 reversings, establish an ejector pin 16 at driving gear 8 rear portions, in addition, heating in this electric iron 4 can be established second gear, by temperature regulating switch 15 controls; The rubber pinch roller also is provided with to promote and turns round, to solve the taking-up problem of last residue welding wire in welding process.
