The specific embodiment
Below lift a preferred embodiment, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
As Figure 1-4, the utility model provides a kind of punching device for pipe fittings, and it comprises a location plug 1, loose core axle 2 and two drifts 3.Certainly, adopting two drifts herein is a kind of giving an example, and in actual conditions, according to different technological requirements, adopts a drift or a plurality of drift all to be fine.Location mandril 1 is sheathed in a pipe fitting 4, the axle 2 of loosing core is sheathed in location mandril 1, radially be provided with a dovetail groove 11 along pipe fitting 4 on one axial end of location mandril 1, play the effect of guiding, certainly the gathering sill of other shapes also is fine, one side of drift 3 is embedded in dovetail groove 11, and the axle 2 of loosing core is for driving the 4 radially outward direction slippages along dovetail groove 11 to pipe fitting of described drift 3.Particularly, the opposite side of drift 3 forms one first drift inclined-plane 31, and the axle 2 of loosing core is provided with corresponding with the first drift inclined-plane 31 one axle inclined-plane 21 of loosing core, and drift 3 is at dovetail groove 11 and loose core between axle inclined-plane 21.That is to say, drift 3 has formed a Wedge mechanism with the axle 2 of loosing core, the first drift inclined-plane 31 support is compeled on the axle inclined-plane 21 of loosing core when the axle 2 of loosing core moves axially along pipe fitting 4, and drift 3 is radially outward moved along pipe fitting 4 dovetail groove 11 is interior, thus realize in pipe fitting to punching.
Punching device for pipe fittings also comprises two punching concave die 5, and punching concave die 5 is positioned at outside pipe fitting 4, and respectively with two corresponding settings of drift 3.So just can avoid the problem of the dinking that may be run into during punching outside to inside by pipe fitting.
Punching device for pipe fittings also comprises two drift resetting means 6, is respectively used to drive the 4 radially inward direction slippages along dovetail groove 11 to pipe fitting of two drifts 3.Particularly, each drift resetting means 6 comprises a pair of drift resetting block 61, the every pair of drift resetting block 61 is fixedly arranged on the axle 2 being oppositely arranged of loosing core, each drift resetting block 61 is provided with a drift resetting block inclined-plane 62, is provided with two second drift inclined-planes 32 corresponding with each drift resetting block inclined-plane 62 respectively on each drift 3.Like this, each resetting block of the drift to drift resetting block 61 inclined-plane 62 supports respectively and compels two the second drift inclined-planes 32 when the axle 2 of loosing core moves axially along described pipe fitting 4, make drift 3 interior along the radially inwardly slippage of described pipe fitting 4 at dovetail groove 11, thereby realize resetting of drift after punching completes.
Punching device for pipe fittings also comprises axle the slide block 22 and axle drive block 23 of loosing core of loosing core, and the axle 2 of loosing core is affixed with the axle slide block 22 of loosing core, and the axle drive block 23 of loosing core moves axially along pipe fitting 4 together with the axle 2 of loosing core for the driving axle slide block 22 of loosing core.The axle drive block 23 of loosing core forms Wedge mechanism with the axle slide block 22 of loosing core.
Punching device for pipe fittings also comprises a punching concave die slide block 51 and a punching concave die drive block 52, and punching concave die 5 is affixed with punching concave die slide block 51, and punching concave die drive block 52 is for driving punching concave die slide block 51 to move radially along pipe fitting 4 together with punching concave die 5.Punching concave die drive block 52 forms Wedge mechanism with punching concave die slide block 51.
Punching device for pipe fittings also comprises a location plug fixed block 12 and a base plate 7, and location mandril 1 is fixedly arranged on location mandril fixed block 12, and location mandril fixed block 12 is fixedly arranged on base plate 7.
In actual mechanical process, loose core axle drive block 23 and punching concave die drive block 52 all is fixed on a pressing plate 8, by the external drive power source, pressing plate 8 is pressed down, thereby the axle drive block 23 of loosing core acts on the axle slide block 22 of loosing core by Wedge mechanism, change the motion of vertical direction into horizontal motion, the driving axle slide block 22 of loosing core moves axially along pipe fitting 4 together with the axle 2 of loosing core, and punching concave die drive block 52 acts on punching concave die slide block 51 by Wedge mechanism, change the motion of vertical direction into horizontal motion, drive punching concave die slide block 51 to move radially along pipe fitting 4 together with punching concave die 5.Because the axle drive block 23 of loosing core is different with the setting position of punching concave die drive block 52 ramps, the time that both are driven also has successively.Punching concave die drive block 52 can first drive punching concave die 5 to be pressed on pipe fitting, the axle drive block 23 of loosing core subsequently drives the axle 2 of loosing core to move again, thereby support and compel the first drift inclined-plane 31 by the axle inclined-plane 21 of loosing core again, drift 3 is radially outward moved along pipe fitting 4 dovetail groove 11 is interior, realize in pipe fitting to punching.
After completing punching, in pressing plate 8 meetings, move, the axle 2 of loosing core is by spring reset, and the drift resetting means 6 now be installed on the axle 2 of loosing core can retract original position by drift 3.Above described the process that drift resets, do not repeated them here.
Although more than described the specific embodiment of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection domain of the present utility model is limited by appended claims.Those skilled in the art, under the prerequisite that does not deviate from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these changes and modification all fall into protection domain of the present utility model.
