Product Description

(AJH21 Series) C-Frame Single Crank Presses/Pressing Machine (with fixed stroke)

C-frame presses, also known as gap frame presses, open frame, or open front presses, consist of a frame shaped roughly like the letter "C, "with a bed at the bottom and a guide and support structure for a moving ram at the top. The frame may be a large casting, or a steel fabrication that is either welded or riveted. The bed, in turn, may be an integral part of the frame, or it may be moveable to adjust the distance between the ram and bed.
The SJH21 series C press is with dry clutch and hydraulic overload with steel welded body and good rigidity. This C frame power press has six guide rail sliders, long and high precision, which can prolong its life span.
The crank-shaft is placed vertically, so the structure is compact and the contour is beautiful. It is equipped with combined wet pneumatic friction clutch, so the engagement is smooth, the action is agile and the noise is low. And this crank press is of convenient maintenance. The C frame power press has hydraulic overload protection device which can stop in emergency automatically to enhance the press and die safety for an easy use. This single crank press owns concentrated lubrication system with oil alarm function to ensure that the machine runs smoothly. The high speed press is controlled by LC electric centralized system, with emergency stop, inch, single, continuous operation specification with a drive output shaft, automatic feeding, and air cushion device.
