Description

Technical Field

[0001] The invention relates to the technical field of hydraulic presses, in particular to a hydraulic press slide locking device and the hydraulic press. Background Art

[0002] A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. A hydraulic press is generally composed of three parts: the machine (host), the power system, and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses. Its principle is to use Pascal's law to make a machine that uses liquid pressure transmission. There are many types. Of course, the uses are also varied according to needs. For example, according to the type of liquid that transmits pressure, there are two major categories: oil presses and water presses.

[0003] The hydraulic press works by the hydraulic cylinder driving the hydraulic actuator. However, when the hydraulic press is used in different occasions, its flexibility requirements are higher. Most hydraulic presses are very rigid and cannot reasonably adjust the hydraulic pressure according to actual needs. The pressure adjustment range is very narrow and not suitable for the actual needs of the work. However, with the advancement of science and technology, hydraulic presses that can realize high-low pressure conversion have also appeared one after another. This type of hydraulic press can adjust the sequence valve or shift switch on the hydraulic press according to the needs of the actual load to achieve the actual required pressure. For example: low pressure is used during normal feeding, and when the hydraulic press needs to exert force, it is converted to a high-pressure output state as the load increases. This solves the problem of use under high load conditions, especially when the hydraulic press is used for crushing, cutting, punching, bending, tightening and other working conditions, a hydraulic press that can bear high loads is needed.

The present invention sleeves the guide column, and when the mobile workbench moves downward, the sleeve is driven to move downward together, and when the mobile workbench moves upward, the sleeve is driven to move upward together, so that the guide column is isolated from dust from the outside, the workload of maintenance is reduced, and the service life of the hydraulic press is effectively improved.
