The commonly used extruder now has a fixed frame installed vertically on the bottom plate, with a guide column on the fixed frame and two guide columns. The two adjustment rods are set in the middle of the guide columns, and the upper and lower ends of the adjustment rods are fixed on the fixed frame and bottom plate through bearing seats. The upper right hand thread is set on the adjustment rod, the lower left thread is set on the lower part, and the guide sleeve is fixed on the rear surface of the lower and upper fixed plates.
The advantage of the current new type of extruder is that by rotating the adjustment rod, the gap between the upper and lower traction components can be quickly adjusted to adapt to the traction force of pipes with different diameters. The operation is simple, avoids traction wheels, greatly improves welding efficiency, and the working efficiency of the extruder. The pressure fluctuation reduction method of the current hydraulic system extruder, the pressure oil output of the hydraulic system, first enters the pulsation damper through the hydraulic pump component, And the noise transmitted from the hydraulic pump components is filtered, while the pulsation damper and output pressure oil filter and compress the peaks and valleys simultaneously.
Due to the fluctuation pressure output by the hydraulic pump unit of the extruder, the valve block is then transmitted from the entire vehicle body to the hydraulic cylinder through the hydraulic cylinder. The control valve block controls the actions related to extrusion, fundamentally overcoming the pressure fluctuation caused by the rotation of the oil pump, ensuring the smoothness of the output, thereby reducing the impact on the hydraulic components, improving the service life and stability of the hydraulic components, and increasing the extrusion pressure of the extruder, And the stability and reliability of extrusion speed control.
