Joint pin 9 by four angle ends between described top panel 6 and described lower panel 11 is connected and on described every joint pin 9, is socketed a spring 10: being connected to of 6 four angle ends of described top panel and described joint pin 9 is affixed; described lower panel 11 4 angle ends with the socket that is connected to described joint pin 9, described lower panel 11 can (under the pressure of punch press) with respect to top panel 6 be drawn in or (under the effect of spring 10) launches.
The interior fixed installation drift 14 of drift fixing hole 7 in the middle of described top panel 6, the lower end of the drift 14 after installation can slide up and down through the drift through hole 12 in the middle of described lower panel 11.
Described punching counterdie 2 is made to downward " U " shape structure, both, on described punching counterdie 2, be provided with inverted U-shaped hole 18.The counterdie drift through hole 16 that a diameter is greater than described drift 14 diameters is set on the top in described inverted U-shaped hole 18; A locating dowel 15 and low groove 17 are set in the upper surface of described punching counterdie 2.Described locating dowel 15 is counter structure with described the second locating hole 1502 and described the first locating hole 1501, and described the first locating hole 1501 and described the second locating hole 1502 can be socketed in described locating dowel 15.Described low groove 17 and described upper groove 13 are corresponding groove structure, while closing mill, can locate and block air conditioner connecting pipe to be processed 4.
Described punching counterdie 2 is placed on described base plate 3.While needing, can a limited block 19 be set in a side of base plate 3 the above punching counterdie 2: the groove 20 that energy clamping air conditioner connecting pipe 4 is set on the top of described limited block 19.For meeting design requirement, while needing, ramp structure can be made in the top of described limited block 19.
Described punch upper die 1 and described punching counterdie 2 are connected in series by two joint pins 8: described punch upper die 1 by described two joint pins 8, can slide up and down and with described punching counterdie 2 matched moulds.
The method that the present invention utilizes the punching die of described car air-conditioner pipeline to carry out punching to car air-conditioner pipeline is:
(1) utilize the punching die of punch press and described car air-conditioner pipeline to carry out " punching " to air conditioner connecting pipe 4, described punching die is installed together with punch press.
(2) air conditioner connecting pipe 4 that needs punching is placed in the low groove 17 of described punching counterdie 2 upper surfaces.
While needing, can adopt limited block 19 and 20 pairs of described air conditioner connecting pipes 4 of groove on base plate 3 to carry out spacing.
(3) start punch press, by punch press fixed leg 5, the top panel of described punch upper die 16 and lower panel 11 are pressed down, under the location of locating dowel 15 and the second locating hole 1502 and the first locating hole 1501, described lower panel 11 is stuck on the low groove 17 of described punching counterdie 2 upper surfaces by the upper groove 13 of its lower surface, and air conditioner connecting pipe to be processed 4 is blocked.
(4) under the pressure of punch press, the air conditioner connecting pipe 4 that the lower end of described drift 14 is connected in punching counterdie 2 low grooves 17 through 12 pairs of drift through holes in the middle of described lower panel 11 carries out punching, and described drift 14 is (in the seeing accompanying drawing 2 on air conditioner connecting pipe 4 position of punching) that carry out " punching " in the side of air conditioner connecting pipe 4.
(5) lower end after described drift 14 punchings is counterdie drift through hole 16, and therefore, the metal fragment that punching produces can directly drop along described counterdie drift through hole 16.
(6) after punching completes, by described punch upper die 1(by punch press fixed leg 5) upwards lift, the air conditioner connecting pipe 4 that completes punching is taken off from described punching counterdie 2.
The great advantage of the hole-punching method of a kind of car air-conditioner pipeline of the present invention is:
During punching, utilize the mill that closes of punch upper die 1 and punching counterdie 2 that air conditioner connecting pipe 4 is blocked, drift 14 punches from the side of air conditioner connecting pipe 4, like this, the metal fragment that punching produces can directly drop by counterdie drift through hole 16, avoid metal fragment to stay in air conditioner connecting pipe 4, thereby improved the quality of product.During due to punching, on air conditioner connecting pipe 4, can not produce burr and metal fragment (aluminium bits, copper scale), therefore, no longer need the anti-dandruff deburring operation after punching, can enhance productivity, reduce cost of labor.
