Description
Technical field
This utility model is related to refrigeration part or sky in machining technology field, more particularly to air conditioner parts process technology
Adjust vaporizer, condenser welding shunting pipe fitting thin-wall copper pipe punching flange hole technology.
Background technology
The coolant media of domestic air conditioning is all to be delivered to condenser and vaporizer via refrigerant pipe, and refrigerant pipe generally has gas collection
The big class such as pipe, collector tube, and generally by discharge and multiple arms are brazed combines on collecting pipe component.Collect in the industry at present
On trachea, generally using hole forming is pulled out, its principle is similar punching press hole-crimped forming technique, that is, design and produce one for the processing of tap
Set mechanism insertion copper pipe is simultaneously connected on the pallet for pulling out hole machine, and when device tray travels forward, the mechanism can be by the axial direction of equipment
Power is changed into radial force and first goes out bottom outlet to copper pipe in die cavity, as lathe pallet continues to move ahead, the bottom outlet that goes out is carried out
Hole flanging.The existing hole drift pre-punched hole that pulls out is circle, and after piercing and flanging, section is tooth arc, during with branch pipe welding, fill solder
Area is little, and branch pipe welding is insecure, and easily cracking causes product leakage.At present, lack one kind on market and can overcome above-mentioned lacking
Sunken thin-wall copper pipe tube wall pulls out aperture apparatus.
Utility model content
The purpose of this utility model is that providing a kind of thin-wall copper pipe tube wall pulls out aperture apparatus, and after punching hole flanging, orifice part is put down
Together, advantage is provided for welding.
For achieving the above object, thin-wall copper pipe tube wall of the present utility model pulls out aperture apparatus and includes pulling out hole core retainer plate and pull out Kong Xin
Bar, pulls out and is provided with opening at the top of the core retainer plate of hole, and pulling out at opening is provided with the core retainer plate of hole pulls out hole drift, and pulling out hole drift includes hole flanging punch
With pre- stamping punch, inclined-plane of the hole flanging punch bottom surface for right low left high, hole flanging punch are slidably matched with the opening；Hole flanging punch
Top is provided with pre- stamping punch, and the horizontal cross-section of pre- stamping punch is less than the horizontal cross-section of hole flanging punch, and pre- stamping punch is opened with described
There is between the side wall of mouth gap；The horizontal cross-section ovalize of pre- stamping punch；
Described pull out hole core bar and pulled out in the core retainer plate of hole by being slidably connected at from left to right, the right part for pulling out hole core bar is to turn over described
The inclined-plane that the bottom surface of hole drift is adapted, the right-hand member inclined-plane for pulling out hole core bar are located at below hole flanging punch and bottom surface with hole flanging punch
It is slidably matched.
The top surface of the pre- stamping punch is high outside and low outside curved surface.
This utility model simple structure, easy to use, it is to avoid after piercing and flanging, section was tooth arc and branch pipe welding in the past
When, fill solder area is little, the unstable problem of branch pipe welding, and when expanding follow-up branch pipe welded directly to the run pipe, the filling area of solder, prevents
Branch pipe welding phenomenon loosely.
Description of the drawings
Fig. 1 is structural representation of the present utility model before punching；
Structural representation of the present utility model when Fig. 2 is punching；
Fig. 3 is the enlarged drawing in Fig. 1 at A；
Fig. 4 is the top view for pulling out hole drift.
Specific embodiment
As shown in Figures 1 to 4, thin-wall copper pipe tube wall of the present utility model pulls out aperture apparatus and includes pulling out hole core retainer plate 1 and pull out Kong Xin
Bar 2, the top for pulling out hole core retainer plate 1 are provided with opening 3, and pulling out at opening 3 is provided with hole core retainer plate 1 pulls out hole drift, and pulling out hole drift includes turning over
Hole drift 4 and pre- stamping punch 5, inclined-plane of 4 bottom surface of hole flanging punch for right low left high, hole flanging punch 4 are slided with the opening 3 and are matched somebody with somebody
Close；The top of hole flanging punch 4 is provided with pre- stamping punch 5, and the horizontal cross-section of pre- stamping punch 5 is less than the horizontal cross-section of hole flanging punch 4, and
There is gap between the side wall of pre- stamping punch 5 and the opening 3；The horizontal cross-section ovalize of pre- stamping punch 5；
Described pull out hole core bar 2 and pulled out in hole core retainer plate 1 by being slidably connected at from left to right, the right part for pulling out hole core bar 2 is and institute
The inclined-plane 6 that the bottom surface of hole flanging punch 4 is adapted is stated, the right-hand member inclined-plane 6 for pulling out hole core bar 2 is located at below hole flanging punch and is rushed with hole flanging
4 bottom surface is slidably matched.
The top surface 7 of the pre- stamping punch 5 is high outside and low outside curved surface.So that the top of pre- stamping punch 5 plays knife
The effect of sword, it is easier to complete punching operation.
During work, hole core retainer plate 1 will be pulled out and be put in the copper pipe for treating punching, make hole flanging punch 4 and the alignment of pre- stamping punch 5 treat punching
Position, then promote to the right and pull out hole core bar 2, make to pull out hole core bar 2 and move right.Hole core bar 2 is pulled out when mobile, its right-hand member oblique
Face 6 will be pulled out hole drift and be pushed up, and make the inwall of the top pressure copper pipe upwards of pre- stamping punch 5.Between the top senior middle school of pre- stamping punch 5
Low, make the top of pre- stamping punch 5 play a part of blade, can relatively easily go out elliptical aperture.Pre- stamping punch 5 is upwards
After stretching out copper pipe, hole flanging punch 4 upwardly, at the elliptical aperture of copper pipe, realizes hole flanging action.
Experiment shows that pre-punched hole punching is elliptical aperture, and aperture flushes very much after hole flanging, it is to avoid section after conventional piercing and flanging
For tooth arc and branch pipe welding when, fill solder area is little, the unstable problem of branch pipe welding, be improve subsequent product matter
Amount provides basis.
Above example is only in order to illustrative and not limiting the technical solution of the utility model, although reference above-described embodiment pair
This utility model has been described in detail, it will be understood by those within the art that：Still this utility model can be entered
Row modification or equivalent, without deviating from any modification or partial replacement of spirit and scope of the present utility model, which all should
Cover in the middle of right of the present utility model.
