Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, set forth the present invention further.
As shown in figure 1 and 2, the difference of common plastics sheet material and continuous variable cross section plastic plate clearly, continuous variable cross section plastic plate is because there is all size requirement, according to present processing method, not only time-consuming but also take material, therefore devise a kind of specially for the extrusion equipment of continuous variable cross section plastic plate.
As shown in Figure 3, continuous variable cross section plastic plate extrusion equipment is made up of servo hydraulic cylinder part and extrusion die part.
Servo hydraulic cylinder part is made up of displacement transducer 13, pull bar, hex nut, spring washer, back cylinder cover, O RunddichtringO, wear-resistant guiding ring, magnet, y-type seal ring, cylinder barrel, front end housing, dust ring, front guide pin bushing, piston rod 10, front buffer plunger, sensor bar 14, piston 9, rear buffer plunger, rear guide pin bushing, non-magnetic isolation pad, position magnet, tingle etc.
Connection form is: buffer plunger is arranged on piston rod 10, and piston 9 is arranged on piston rod 10 by magnet connection, and mounting O-shaped sealing ring between piston 9 and piston rod 10, installs y-type seal ring and wear-resistant guiding ring between piston 9 and cylinder barrel.Buffer plunger and rear guide pin bushing after the rear end of piston rod 10 is installed.Front guide pin bushing is arranged between front end housing and piston rod 10, and front end housing is installed y-type seal ring and dust ring.Displacement transducer 13 by flange thread connection on back cylinder cover, between mounting O-shaped sealing ring, in the endoporus of sensor bar 14 built-in piston bar 10 (gap), on the piston rod 10 of the built-in oil cylinder of position magnet.Between position magnet and piston rod 10, non-magnetic isolation pad is installed, and fixes with tingle.Front end housing, back cylinder cover and cylinder barrel are fixed by pull bar, spring washer and hex nut, mounting O-shaped sealing ring between cylinder barrel and front and back cylinder cap.
