Bar has multiple smooth plane, and the slip of adjusting slider 108 is convenient, and during slip, position is difficult to
Variation.Drive link 202 has two the first inclined-planes 203 being oppositely arranged, two the first inclined-planes 203
Lay respectively at before drive link 202 101 and below 102, before drive link 202 101 and after
Face 102 is identical with the referential of before rectangular block 109 101 and below 102, two the first inclined-planes
The incline direction of 203 is identical, by one end of drive link 202 its other end oblique.
Rotate regulation screw mandrel, adjusting slider 108 along the axis of adjusting screw 107 relative to punch die master
Body 100 slides, in order to improve the imporosity of adjusting slider 108 and die body 100, in punching
Arranging two the first chutes 204 in mould main body 100, two drive links 202 are positioned at two the first chutes
In 204, i.e. one drive link 202 is slidably connected with the first corresponding chute 204, drive link 202
In corresponding chute, the bearing of trend along chute slides, and the structure of the first chute 204 is preferably arranged to
Dovetail groove or T-slot, adjusting slider 108 and die body 100 by dovetail groove or T-shaped
Groove clamping, attachment structure is more tight, and matching relationship is good, slides more steady.
Adjusting slider 108 slides along the axis of adjusting screw 107 relative to die body 100, adjusts
Joint slide block 108 is in transmission connection in stroke slider 112, i.e. adjusting slider 108 slides, and drives stroke sliding
Block 112 slides, and the glide direction of stroke slider 112 is perpendicular to the axis direction of tubing installing hole 111,
Meanwhile, the glide direction of stroke slider 112 is perpendicular to the glide direction of adjusting slider 108, i.e. regulates
The axis two of the glide direction of slide block 108, the glide direction of stroke slider 112 and installing hole 111
Two is vertical, and stroke slider 112 is slided along the axis direction being perpendicular to tubing installing hole 111, the most permissible
Adjust the gap between tubing and stroke slider 112, and then ensure that various sizes of tubing can be accurate
Location, adjust the suitable gap between tubing and stroke slider 112, it is ensured that the quality of punching
And ensure the mold use life-span.When stroke slider 112 arranges one, it is merely able to adjust tubing one
The gap of side, the scope of adjustment is little, has certain limitation.
Further, stroke slider 112 is provided with two, and two stroke slider 112 are positioned at installing hole
The both sides of 111, each stroke slider 112 is corresponding to a drive link 202, the position of stroke slider 112
Putting the position one_to_one corresponding design with two drive links 202, each drive link 202 drives a stroke
Slide block 112 slides.The rectangular shape of stroke slider 112, each stroke slider 112 has a guiding
Groove 303, the length of gathering sill 303 extends along the axis direction of drive link 202, and gathering sill 303 has
Having two the groove sidewalls being oppositely arranged, each groove sidewall is set to the second inclined-plane 305, and two second oblique
Face 305 coordinates with two the first inclined-plane 203 one_to_one corresponding, and when adjusting slider 108 moves, first is oblique
Face 203 extrudes the second inclined-plane 305, and then drives the second inclined-plane 305 to slide, and is matched by inclined-plane
Connected mode simple and reliable, transmission is accurate, it is possible to save installing space.Gathering sill 303 preferably sets
Being set to dovetail groove or T-slot, matching relationship is good, slides more steady.
After tubing is installed, two stroke slider 112 carry out the location of tubing jointly, and tubing is sliding with stroke
Block 112 contacts, in order to ensure that stroke slider 112 does not scratch the surface of tubing, in each stroke slider
Bearing 302 is installed on 112, i.e. forms slide block and include slider body 301 and bearing 302, gathering sill 303
Being arranged on slider body 301, adjusting slider 108 drives slider body 301 to slide, and bearing 302
