Abstract
The utility model discloses a heat exchanger tube group constant diameter flanging device which comprises a flanging die, a stop pattern die and a threaded die unloading assembly, wherein the longitudinal size of the front end of the flanging die is larger than the horizontal size thereof, the back end of the flanging die is connected with the threaded die unloading assembly, and the stop pattern die is arranged on the front end of the flanging die. The device adopts the flanging die whose horizontal size is smaller to extend into a copper tube, and drives the flanging die to rotate through the rotation of the threaded die unloading assembly, and enlarges holes through the continuous rotation under the effect of the longitudinal size of a larger flanging die equal to the outer diameter of the copper tube, simultaneously, the copper tube is kept still under the barrier effect of the stop pattern die, thereby producing the constant diameter flange of the copper tube through the rotation pulltrusion. The device can conveniently process the constant diameter flanging hole on a main tube, increases the welding length and strength, and greatly reduces the occurrence of welding point leakage.
Description
[technical field]
The utility model belongs to air-condition heat exchanger processing and manufacturing field, especially to the device of the isometrical flange of air-condition heat exchanger pipe group.
[technical background]
In the air-condition heat exchanger, interconnect the welding of to peg graft between the copper pipe, leak, substantially all adopt structure shown in Figure 1, on being responsible for, do the flange hole, arm is inserted in the flange hole weld again for strengthening weld strength, reducing.This flange hole all is to adopt withdrawing pattern formula hemmer to make, circular shape mould is put into copper pipe to be pulled out again, but withdrawing pattern formula hemmer can't be processed the flange hole for the isometrical grafting class of copper pipe pipe group, just can not be put into copper pipe inside greatly because the shape mould is the same with the copper pipe external diameter.Therefore, employing is at present opened the flange hole and is only limited to not isometrical flange on copper pipe, and isometrical can't flange.
Yet the processing request of the isometrical grafting weldering of Tube Sheet of Heat Exchanger group is more and more on the refrigeration industry, can only adopt structure shown in Figure 2 at present, directly punching welding on being responsible for, but, directly the welding section of punching welding is too short, and weld strength is not enough, pad takes place easily leak.
[summary of the invention]
The purpose of this utility model is exactly in order to solve problems of the prior art, proposes the isometrical hemmer of a kind of Tube Sheet of Heat Exchanger group, can process isometrical flange hole on being responsible for, and improves weld length and intensity, significantly reduces the leakage of pad.
For achieving the above object, the utility model patent has proposed the isometrical hemmer of a kind of Tube Sheet of Heat Exchanger group, comprise that flange die, stop bit pattern, screw thread move back membrane module, the front end longitudinal size of described flange die is greater than lateral dimension, the rear end of flange die is moved back membrane module with screw thread and is connected, and the stop bit pattern is arranged on the front position place of flange die.
As preferably, described screw thread moves back membrane module and comprises the rear support that has internal thread, has externally threaded threaded rod, and described threaded rod and rear support are by being threaded, and the rear end of flange die is connected with the front end of threaded rod.
As preferably, the rear end of described threaded rod also is provided with handle.
As preferably, also comprise base and preceding bearing, described preceding bearing is fixed on the front end of base, and rear support is fixed on the rear end of base, and described stop bit pattern is fixed on the preceding bearing.
As preferably, described stop bit pattern is provided with arc groove.
The beneficial effect of the utility model patent: the utility model adopts the less flange die of lateral dimension to stretch in the copper pipe, and drive the flange die rotation by the rotation that screw thread moves back membrane module, under the effect of the bigger longitudinal size suitable of flange die with the copper pipe external diameter, constantly reaming is carried out in rotation, simultaneously, under the barrier effect of stop bit pattern, it is static that copper pipe keeps, and so makes the isometrical flange of copper pipe by the rotation pultrusion.The utility model can process isometrical flange hole easily on being responsible for, improved weld length and intensity, has significantly reduced the generation of pad leakage situation.

[specific embodiment]
Consult Fig. 4,5,6,7, the isometrical hemmer of a kind of Tube Sheet of Heat Exchanger group comprises that flange die 1, stop bit pattern 2, screw thread move back membrane module 3, the front end longitudinal size L of described flange die 1
1Greater than lateral dimension L
2, the rear end of flange die 1 is moved back membrane module 3 with screw thread and is connected, and stop bit pattern 2 is arranged on the front position place of flange die 1.Described screw thread moves back membrane module 3 and comprises the rear support 31 that has internal thread, has externally threaded threaded rod 32, and described threaded rod 32 and rear support 31 are by being threaded, and the rear end of flange die 1 is connected with the front end of threaded rod 32.The rear end of described threaded rod 32 also is provided with handle 33.Also comprise base 4 and preceding bearing 5, described preceding bearing 5 is fixed on the front end of base 4, and rear support 31 is fixed on the rear end of base 4, and described stop bit pattern 2 is fixed on the preceding bearing 5.Described stop bit pattern 2 is provided with arc groove 21.This flange die 1 can adopt hook-type flange die as shown in Figure 5.
Flange die 1 and stop bit pattern 2 need be according to copper pipe caliber processing, the copper pipe that a cover flange die 1 and stop bit pattern 2 can only supporting a kind of external diameters, and screw thread moves back 3 of membrane modules can be general.Flange die 1 is because of longitudinal size L
1Greater than lateral dimension L
2, and therefore the bottom outlet size lateral dimension of opening on the copper pipe, can stretch into from the bottom outlet that copper pipe is accomplished fluently also less than caliber, with the longitudinal size L of flange die 1
1Radially place along copper pipe, can put into copper pipe inside to flange die 1 working portion like this.Again flange die 1 is coupled together by stop bit pattern 2 and threaded rod 32 usefulness pins.
Cardinal principle: swing handle 33, make flange die 1 rotate together and outwards move in copper pipe inside, but copper pipe by screens on stop bit pattern 2, so when flange die 1 rotation pultrusion during to the copper pipe outside, copper pipe is made as shown in Figure 3 flange hole owing to be subjected to flat hole that flange die rotation extruding will accomplish fluently originally during the course.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
