Abstract

The utility model relates to a ring welding tip with hot gas, which is provided with a wind gun joint. The clamp nut is arranged on top of and outside the wind gun joint, and the bottom of the wind gun joint is connected with the upside of the bell mouth for dispelling wind. In addition, a sealing board is arranged at the bottom of the bell mouth for dispelling wind. The technical proposal: four square outlet air holes are arranged on the sealing board of the bell mouth, a ring outer circumferential boarding is arranged at the bottom of the sealing board, and the ring inner circumferential boarding is arranged on the inside of the outer circumferential boarding. In addition, a ring passage is connected with the outlet air hole. The utility model overcomes the shortcomings in prior art such as difficulties in welding, high cost and low welding quality, and provides the ring welding tip of hot gas with the simple structure, low cost, homogeneous blowing, and perfect welding effect.

Description

A kind of annular hot blast tip

[technical field]

The utility model relates to a kind of noncontact welder, a kind of hot blast tip of more specifically saying so.

[background technology]

At present, the hot blast tip that uses in the industry and sell is to have 4 to surround square bar hole on the horn mouth hush panel, to flatten in the end patchhole of pipe, the other end is done the noncontact welding as air outlet, be difficult for controlling shape exactly because pipe is flattened, slit inequality between pipe and the horn mouth hush panel is difficult for welding, the production cost height, as an end of air outlet too owing to mouth of pipe slit inequality causes the uneven welding quality that influences the IC pin of air output.

[summary of the invention]

The utility model purpose is to have overcome in the prior art to be difficult for welding, the production cost height, and the deficiency that welding quality is not good provides a kind of simple in structure, production cost is low, air-out is even, welding effect is better hot blast tip.

The utility model is achieved through the following technical solutions:

A kind of annular hot blast tip, comprise the air pressure gun joint, the air pressure gun upper end of joint outside is provided with clamp nut, air pressure gun joint lower end is connected with diffusing air horn mouth upper end, diffusing air horn mouth lower end is provided with the horn mouth hush panel, it is characterized in that the horn mouth hush panel is provided with 4 and surrounds square exhaust vent, is provided with the peripheral board that surrounds annular in the lower end of hush panel, be arranged with the interior coaming plate that surrounds annular in peripheral board, the passage and the exhaust vent that form an annular between peripheral board and the interior coaming plate connect.

Aforesaid a kind of annular hot blast tip is characterized in that described exhaust vent is for arranging the corresponding slot of pin with IC;

Aforesaid a kind of annular hot blast tip is characterized in that side's annular that described peripheral board and interior coaming plate are buckled into by two L type thin plates.

Aforesaid a kind of annular hot blast tip is characterized in that side's annular that described peripheral board and interior coaming plate are buckled into by the thin plate of two U types.

Aforesaid a kind of annular hot blast tip is characterized in that described peripheral board and interior coaming plate are by the thin plate side of a surrounding annular.

The utility model has following advantage:

1, simple in structure, the slit is even, welds easily when making the hot blast tip, and production cost is low;

Welding IC pin effect was better when 2, the hot blast tip was evenly used in air-out.

[specific embodiment]

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

A kind of annular hot blast tip, comprise air pressure gun joint 1, the air pressure gun joint 1 upper end outside is provided with clamp nut 2 and is used for being connected of fastening air pressure gun joint 1 and air pressure gun, air pressure gun joint 1 lower end is connected with diffusing air horn mouth 3 upper ends, diffusing air horn mouth 3 lower ends are provided with horn mouth hush panel 4, horn mouth hush panel 4 is provided with 4 and surrounds square exhaust vent 401, be provided with the peripheral board 5 that surrounds annular in the lower end of hush panel 4, be arranged with the interior coaming plate 6 that surrounds annular in peripheral board 5, the passage and the exhaust vent 401 that form an annular between peripheral board 5 and the interior coaming plate 6 connect.Be used for all having on the four direction IC pin welding of pin, described exhaust vent 401 is and the corresponding slot of IC row's pin; Peripheral board 5 and interior coaming plate 6 all are side's annulars that the thin plate by two L types or U type is buckled into, or by the thin plate side of a surrounding annular, are convenient to manufacture.

When using the utility model to carry out the noncontact welding, annular hot blast tip is connected on the air pressure gun of hot blast welding machine, air-flow comes out from air pressure gun, enter the air pressure gun joint 1 of hot blast tip, thermal current is spread in the circular passage that is filled in after back 4 exhaust vents 401 from horn mouth hush panel 4 flow out between peripheral board 5 and the interior coaming plate 6 by the air horn mouth 3 that looses, the circular passage faces the IC row pin that is placed on the circuit board, hot blast comes out to face to blow on the IC row pin from the circular passage, and IC row pin promptly all can be soldered.
