Abstract
The utility model discloses a tube distribution hole flanging mould, which comprises a support and a bolt. The support comprises a top plate at the upper end and an arched plate at the lower end. An upper through hole is arranged on the top plate, a lower through hole is arranged at the top of the arched plate, the bolt penetrates through the upper through hole and the lower through hole from top to bottom and is in running fit with the upper through hole and the lower through hole, the lower end of the bolt is provided with a big-end-down and conical nut in threaded fit with the bolt, the maximum cross sectional area of the nut is smaller than the cross sectional area of the lower through hole, and a force application rod is arranged on a screw head. A distribution hole of an existing common copper tube is stretched to form a flanging, so that the effective welding area of the distribution hole is increased. After distribution tubes are welded, the copper tube and the distribution tubes are connected reliably. Besides, the tube distribution hole flanging mould belongs to the technical field of stretching devices.
Description
Technical field
The utility model belongs to the device technique field of drawing high, and especially relates to a kind of body tap hole flanging die.
Background technology
The copper pipe of existing air-conditioner fin heat exchanger is provided with a plurality of tap holes that are used to connect isocon, isocon is inserted in the tap hole of copper pipe, then the tap hole inner ring on isocon and the copper pipe is welded together.Following deficiency is left in this welding: because the copper pipe wall thickness is thinner, make that isocon and tap hole efficient weld area are little, weld strength is low, and it is unreliable that isocon is connected with copper pipe, and isocon is prone to come off with copper pipe.Therefore, a kind of equipment that can enlarge copper pipe tap hole efficient weld area of invention has been extremely urgent thing.
The utility model content
The utility model technical problem to be solved is: a kind of body tap hole flanging die is provided, and tap hole and the effective contact area of isocon on this formed in mould copper pipe are big, and weld strength is high, and isocon is connected reliably with copper pipe.
The technical scheme that the utility model is taked is: a kind of body tap hole flanging die; It comprises a support and a bolt, and support comprises the top board of upper end and the arc arch bar of lower end, and top board is provided with through hole; The top of arc arch bar is provided with lower through-hole; The axis of last through hole overlaps with the prolongation of the axis of lower through-hole, and bolt is rotatably assorted in last through hole and lower through-hole, and the spiral shell head axial limiting of bolt is on top board; The bolt lower end is provided with match up-small and down-big of bolt thread and is conical nut, and nut maximum cross section area is less than the lower through-hole cross-sectional area.
As improvement, Luo Toushang is provided with a force application rod, is convenient to the turn bolt.
The beneficial effect of the utility model is: the stretch tap hole of existing common copper pipe of the utility model forms a flange; Make the efficient weld area of tap hole increase; Be that copper pipe is connected reliably difficult drop-off with the isocon isocon after the isocon welding with copper pipe.

The specific embodiment
Below be the utility model preferred embodiment, but therefore do not limit the protection domain of the utility model.
With reference to Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; A kind of body tap hole flanging die, it comprises a support 1 and a bolt 2, support 1 comprises the top board 11 of upper end and the arc arch bar 12 of lower end; Top board 11 is provided with through hole, and the top of arc arch bar 12 is provided with lower through-hole 12.1.The axis of last through hole overlaps with the axis prolongation of lower through-hole 12.1, just goes up lower through-hole and is a line setting.Bolt 2 passes through hole and lower through-hole 12.1 from top to bottom and is rotatably assorted with both, and the bar portion that just refers to bolt 2 that is rotatably assorted can slide up and down in last lower through-hole and rotate.Spiral shell head 21 axial limitings of bolt 2 are meant that spiral shell head 21 is positioned on the top board 11 all the time on top board 11, spiral shell head 21 can not be stuck on the top board 11 by top board 11.Bolt 2 lower ends are provided with match up-small and down-big of bolt 2 screw threads and are conical nut 22, and nut 22 maximum cross section areas are less than lower through-hole 12.1 cross-sectional areas, generally as long as nut 22 can just in time pass through lower through-hole 12.1.
The utility model is to realize like this; Copper pipe 4 is placed on the below of support 1 arc arch bar 11; The last through hole of top board 11 and the lower through-hole 12.1 of arc arch bar 12 are passed in the bar portion of bolt 2, insert in the tap hole of copper pipe 4, then nut 22 is screwed on bolt 2; This moment, bolt 2 connected together with copper pipe 4, and is as shown in Figure 2.Because spiral shell head 21 is positioned on the top board 11 of support 1, spiral shell head 21 is provided with a force application rod 3, and nut 22 is being fixed by the leader; Force application rod 3 rotation afterwards drives spiral shell heads 21 rises, and the distance that is equivalent between spiral shell head 21 and the nut 22 is more and more nearer, and copper pipe 4 can be by up carrying slowly; As shown in Figure 3, be stuck on arc arch bar 12 lower surfaces up to copper pipe 4, if continuing application of force rotation spiral shell head 21 this moment; Will produce bigger pulling force between nut 22 and copper pipe 4 tap holes, conical nut 22 will pass the tap hole of copper pipe 4, tap hole is squeezed big; The copper pipe 4 tap holes stretched flange 41 that made progress, as shown in Figure 4.
