Embodiment 1

[0014] The four-column hydraulic press of the present invention includes a column, an upper beam connected to the column, a lower beam and a movable beam, an upper anvil and a lower anvil below the movable beam, and a working cylinder, a return cylinder, a working plunger connected to the working cylinder, A return plunger connected to the return cylinder;

[0015] The column is made of 27SiMn as raw material, and is made through sub-temperature quenching and high-temperature tempering.

[0016] The sub-temperature quenching and high-temperature tempering process is as follows: the 27SiMn sample is heated to 830°C for quenching, and then heated to 560°C for tempering.

Abstract

The invention provides a four-column type hydraulic machine which comprises stand columns, an upper transverse beam connected with the stand columns, a lower transverse beam, a movable transverse beam, an upper anvil below the movable transverse beam and a lower anvil below the movable transverse beam. The four-column type hydraulic machine further comprises a working cylinder, a working plunger connected with the working cylinder and a return plunger connected with a return cylinder; and raw materials of the stand columns are27SiMn, and the stand columns are prepared through subcritical quenching and high-temperature tempering. The four-column type hydraulic machine is provided with the stand columns obtained after subcritical quenching and high-temperature tempering, and has the abrasion-resistant and corrosion-resistant performance.

Description

technical field [0001] The invention relates to a four-column hydraulic press, which belongs to the technical field of machine tools. Background technique [0002] A hydraulic press is a machine that uses hydrostatic pressure to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing process and pressing forming process, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, pressing and so on. [0003] Its principle is to use the mechanical transmission of liquid pressure made by Pascal's law, and there are many types. Of course, the usage is also varied according to needs. For example, according to the type of liquid that transmits pressure, there are two types of hydraulic presses and hydraulic presses. [0004] The total pressure produced by the hydraulic press is relatively large, and it is often used for forging and stamping. Forging hydraulic presses are divided into die...
