The punch pin body comprises a guide portion and a conical portion, wherein the guide portion is used for being inserted into a pipe fitting, the conical portion is used for expanding a horn mouth. The guide portion is arranged at the front end of the conical portion, the guide portion is in a cylindrical shape, and a central vent hole which is communicated with the gas pipe connector is formed in the center of the punch pin body. By means of the punch pin structure, copper scales are removed while the horn mouth is expanded, production procedures are reduced, and production efficiency is improved.
Description
Technical field
The utility model relates to refrigerating field, particularly relates to a kind of punch structure.
Background technology
Condensation pipe of air conditioner can produce a small amount of copper scale in the production process of bell mouth expanding operation, and when tube connector is installed, the residual copper scale in tube connector horn mouth place may enter air-conditioner, causes the system failure of air-conditioner.Therefore need to after tube connector bell mouth expanding operation, with gases at high pressure, blow again the residual copper scale impurity at horn mouth place off.
The drift of traditional approach only has the operation of bell mouth expanding, and air blowing operation is another operation separating separately, and bell mouth expanding operation and air blowing operation are separated operation, makes the manpower production efficiency many and bell mouth expanding of input low.
Utility model content
Based on this, be necessary to only have bell mouth expanding operation for traditional drift, the operation of not blowing, drops into more than manpower and the low problem of production efficiency, and a kind of punch structure is provided.For reaching the purpose of this utility model, adopt following technical scheme:
A punch structure, comprises drift body and gas-tpe fitting;
Described gas-tpe fitting connects described drift body, and described gas-tpe fitting is arranged on all sides of described drift body;
Described drift body comprises that described guide part is cylindrical for inserting guide part in pipe fitting and for the tapered portion of bell mouth expanding, described guide part is arranged at the front end of described tapered portion;
The center of described drift body is provided with the center roof vent that is communicated with described gas-tpe fitting.
More preferably, first through hole that is provided with in the radial direction the described center roof vent of connection of described guide part.
More preferably, the quantity of described the first through hole is a plurality of, and a plurality of described the first through holes are evenly distributed on all sides of described guide part.
More preferably, the junction of described guide part and described tapered portion is for seamlessly transitting.
More preferably, described drift body and described gas-tpe fitting are for removably connecting.
More preferably, described drift body with the connected mode of described gas-tpe fitting for being threaded.
More preferably, the connected mode of described drift body and described gas-tpe fitting is welding.
Punch structure of the present utility model, in all sides of drift body, be provided with gas-tpe fitting, at the center of drift body, be provided with the center roof vent that is communicated with described gas-tpe fitting, make punch structure of the present utility model form the bell-mouthed while at shock pipe fitting, connect extraneous source of the gas, air-flow blows the issuable copper scale of shock off by center roof vent and a plurality of the first through hole.Punch structure bell mouth expanding operation of the present utility model and air blowing operation operate simultaneously, have reduced the operation of operation, have reached the object of cutting personnel, and have improved the efficiency of producing.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the utility model punch structure one embodiment;
Fig. 2 is the cutaway view of punch structure shown in Fig. 1;
Fig. 3 is the broken section front view of punch structure shown in Fig. 1.
The specific embodiment
In order to make the technical solution of the utility model clearer, below in conjunction with accompanying drawing, punch structure of the present utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 3, punch structure 300 1 embodiment of the present utility model comprise drift body 100 and gas-tpe fitting 200, gas-tpe fitting 200 is arranged on all sides of drift body 100, drift body 100 comprises for inserting guide part 120 in pipe fitting 400 and for the tapered portion 130 of bell mouth expanding, guide part 120 is arranged at the front end of tapered portion 130, is provided with the center roof vent 110 being communicated with gas-tpe fitting 200 at drift body 100 center.
More preferably, as a kind of embodiment, first through hole 125 that is provided with in the radial direction connection center roof vent 110 of the guide part 120 of drift body 100.Gas blows to the first through hole 125 by center roof vent 110, under the effect of the gas that the copper scale of generation blows out at the first through hole 125, from the horn mouth inwall of pipe fitting 400, is blown off, is blown pipe fitting 400 under the effect of the gas blowing out at center roof vent 110.
More preferably, as a kind of embodiment, the quantity of the first through hole 125 is a plurality of, and a plurality of the first through holes 125 are evenly distributed on all sides of guide part 120, and the first through hole 125 is uniformly distributed the copper scale that horn mouth place on pipe fitting 400 can be produced and blows totallyer.Preferably, guide part 120 is with the junction of tapered portion 130 for seamlessly transitting, and the connection seamlessly transitting makes the horn mouth shape of processed pipe fitting 400 more regular.Drift body 100 and gas-tpe fitting 200 are for removably connecting, detachable replacing drift body 100 easy to connect or gas-tpe fitting 200, preferably, drift body 100 is with the connected mode of gas-tpe fitting 200 for being threaded, and the drift body 100 being threaded connection and gas-tpe fitting 200 dismountings or replacing are convenient.Drift body 100 also can be welding with the connected mode of gas-tpe fitting 200, and welding manner better tightness, gas leak phenomenon can not occur.
When work, punch structure 300 and pipe fitting 400 impinge upon and on pipe fitting 400, form the bell-mouthed while, gas-tpe fitting 200 is connected extraneous source of the gas, gas enters the center roof vent 110 of drift body 100 by gas-tpe fitting 200, when gas enters into the position of the first through hole 125 on guide part 120, gas blows to through center roof vent 110 and a plurality of the first through hole 125 horn mouth that pipe fitting 400 shocks form respectively, the gas blowing out from the first through hole 125 blows the copper scale of generation off from the horn mouth inwall of pipe fitting 400, the gas blowing out from center roof vent 110 blows out pipe fitting 400 by clashing into the copper scale producing.
The punch structure of above-described embodiment, at shock pipe fitting, form the bell-mouthed while, connect extraneous source of the gas, by clashing into the copper scale producing, blow off, bell mouth expanding completes in same operation with blowing copper scale, reduce the operation of producing, reached the object of cutting personnel, improved the production efficiency of producing horn mouth pipe fitting.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
