1,Four-point crankshaft supporting structure, 2,Imported roller bearing, 3,Automatic oil-forced lubrication system - details see: https://www.machineto.com/j76-series-punching-line-of-straight-side-high-speed-double-crank-precision-press-10133283

Features:

1,Makeup: uncoiler, S-type material straightener, gear exchanger of feeder, lubricating device for material, closed-type double-crank high-speed precision press.

2,Separated-structure and high-rigidity cast iron frame, base and crossbeam are tightened by four tensile screw rods, with high rigigity and less angular deformation.

3,Impored pneumatic combination friction clutch-brake, with low noise, long service life, large clutch torque and small braking angle, to ensure reliable safety and flexible action.

4,Four-point crankshaft supporting structure, enhancing the strength of crankshafts, less deformation, high rigidity and strong load deviation resistant capability.

5,Imported roller bearing as support, ensuring operation stability, less heat and high precision.

6,The structure of guide column and guide pin bushing is adopted, completely eliminating the side force produced by connecting rod on the slide in swing, ensuring the precision of the slide.

7,Slide is guided by clearance-free ball bearing guide column and guide pin bushing, ensuring the precision of the slide.

8,The machine has dynamic balancing system, reducing the noise from vibration, extending the service life of the dies and improving working environment. Hydraulic locking device for adjustment rods, ensuring the precision of bottom dead center.

9,Automatic oil-forced lubrication system, and alarming function for oil route failure.

10,Frequency control motoris adopted, with adjustable strokes.

11,Programmable cam controller(encoder),to ensure convenient operation and reliable performances.

12,Automatic temperature control systemandusing the thermal compensation technologyto control the the position of bottom dead center in high precision.
