Description

Technical Field

[0002] In the application of hydraulic system for round steel cutting, the traditional cutting method often has some problems.

[0003] In the past, it was difficult to control and stabilize the pressure of the hydraulic system when cutting round steel. When the main oil pump supplied oil alone, it might not be able to provide sufficient and stable pressure and speed instantly, resulting in poor cutting effect, such as uneven cuts and incomplete cutting. Moreover, due to the lack of effective pressure supplementation and regulation mechanism, the pressure of the hydraulic oil might fluctuate greatly during the cutting process, affecting the cutting accuracy and stability.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In view of at least one of the above technical problems, the present application provides a round steel cutting hydraulic system, which solves the problem that when the main oil pump supplies oil alone, it may not be able to provide sufficiently large and stable pressure and speed instantly, resulting in poor cutting effect, such as uneven incision, incomplete cutting and other problems.

[0011] The accumulator is also connected to the oil supply mechanism through an electromagnetic overflow valve.

[0012] One of the above technical solutions has at least one of the following advantages or beneficial effects: the round steel cutting hydraulic system arranges the accumulator and the oil supply mechanism to supply oil to the main cylinder on a pipeline, so that when the accumulator is released, the pressure of the oil supply mechanism is rapidly increased under the pressure resistance of the hydraulic oil released by the accumulator. When the pressure of the accumulator is reduced to balance with the pressure of the oil supply mechanism, the accumulator and the oil supply mechanism simultaneously supply oil to the main cylinder to continue advancing, thereby achieving seamless connection during the cutting process, making the pressure and speed stable during the hydraulic cutting process, and achieving a stable round steel cutting effect.
