The thickness of piece 27,26 lower end of frame cutter groove and 25 hinged place of cutter shaft can finely tune along axial grade of cutter shaft 25 or so and move
It is dynamic.
The disc cams structure of humping section in feed system acts on to push bar blank to enter next link, the
One camshaft 11 is positioned with top board crank 13 by holding screw and the shaft shoulder, and 16 one end of L-type connector is equipped with bearing, with cam
The contact of 10 line of disk, 16 other end of L-type connector are fixed by bolt and push plate 6.When blank bar 29 enters in device, first
Camshaft 11 drives cam disc 10 to rotate, and push plate 6 pushes forward, after bar 29 enters V-shaped groove 4.1,10 band of cam disc
Dynamic push plate 6 initially enters the backhaul stage, returns to initial position, after next bar 29 is come in, continues to be pushed forward, so follow
Ring is reciprocal.
Stepper motor 17 transmits motion to the first camshaft 11 by synchronous belt 9, and the first camshaft 11 passes through synchronous belt 9
Camshaft 21 is transmitted motion to, camshaft 21 is rotated with moving cam 18.After bar enters V-shaped groove 4.1, cam 18 is driven
22 ascending motion of elevating lever, elevating lever 22 push lifting slider 4 to rise, and until bar 29 enters extreme higher position, washboard 1 is just forward
Bar 29 is pushed, at this point, cam 18 enters backhaul state, lifting slider 4 falls, and when falling on least significant end, cam 18, which enters, to stop
State, bar enters in V-shaped groove 4.1 next time for waiting.
Material system is rubbed with the hands for pushing bar 29 to carry out rolling cutting, after bar 29 enters on Cutting platform 30, is rubbed with the hands
Plate 1 starts to push 29 rolls forward of bar forward, while pushing down bar 29, when bar 29 rolls across the cutting edge on blade 27 one week
When, that is, the end cut to bar 29 is completed, the waste material cut is fallen into scrap collecting tank by discharge gate, processes stick
Material falls and enters bar collection device.
Blade 27 is mounted in frame cutter groove 26, is coupled between frame cutter groove 27 and cutter shaft 25 with bearing, between frame cutter groove 27
Axially position is realized by cutter shaft 25, and precision is guaranteed with this.Before processing, selecting the length of different processing bars needs
Clamping screw 28 that will be different by manual turn, can select the frame cutter groove 27 of different spacing, to select different length
Cutting mode.
