The working mechanism of adjustable punching device technique scheme and beneficial effect are presented below disclosed in the invention described above：
1）The present invention is moved back and forth by push rod push-and-pull semicolumn pushing block, semicolumn pushing block between support and platen, so,
When being pushed away before push rod, semicolumn pushing block pushes the work forward bar so that upper and lower connecting rod to be opened, and can jack up platen, when push rod reclaims, half
Cylinder pushing block pulls back working beam so that upper and lower connecting rod to be shunk, and platen is carried out into return, whole device is compact-sized, it is possible to reduce
Impact shock and impact noise, reduce power consumption at double, and transmission capacity can amplify more than more times；2）The present invention is by bearing pin
Fixed hub, axle sleeve can move forward and backward in bar shaped bearing hole, when the work head of working beam wears and needs adjustment, pass through tune
Bearing pin position is adjusted section bolt.
The improvement of above-mentioned technical proposal is：Two pieces positioned at the semicolumn pushing block two end faces are fixed with the support
Guide plate.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of adjustable punching device of the embodiment of the present invention.
Fig. 2 is Fig. 1 explosive view.
Fig. 3 is the structural representation of working beam in Fig. 1.
