Abstract

The invention belongs to the technical field of improvement of hydraulic machines, and particularly provides a method and device for enhancing the discharge capacity of an oil inlet channel of an oil cylinder. A multichannel flow increasing communicating vessel is connected between a prefill valve and a main cylinder. An axial through hole is formed in the center of the multichannel flow increasing communicating vessel, and an oil transportation through hole is formed in the side wall of the multichannel flow increasing communicating vessel. The axial through hole is communicated with the oil transportation through hole. The two ends of the axial through hole are communicated with an inner hole of the prefill valve and an inner hole of the cylinder bottom of the main cylinder. The oil transportation through hole is communicated with an external pressure oil pipe. In the improvement process of a hydraulic machine, parts of the main cylinder and the prefill valve are not changed at all, no damage is caused to the main cylinder, and the strength of the main cylinder can not be reduced; the large oil cylinder of the hydraulic machine to be improved does not need to be demounted, suspended, transported, machined again, mounted again and the like, improvement risks are reduced, improvement cost is saved, the improvement period is shortened, and no potential safety hazards are brought to the oil cylinder after the hydraulic machine is improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic press transformation, and specifically relates to a method and device for increasing the flow capacity of an oil inlet channel of an oil cylinder, which is suitable for replacing the transformation method of increasing the number of oil inlet holes on the original oil cylinder or enlarging the diameter of the original oil inlet hole. Background technique [0002] In general, the main cylinder is the most important component in hydraulic presses, especially in medium and large hydraulic presses (including extrusion hydraulic presses, forging hydraulic presses, stamping hydraulic presses, etc.). As the capacity of different hydraulic machines ranges from a few meganewtons to over a hundred meganewtons, the diameter of the main oil cylinder will also increase from several hundred millimeters to more than 3 meters, and the weight of the main oil cylinder will also vary from several tons to over a hun...
