四柱液壓機用途與特點：
　　該系列產品適用于各種可塑性材料的壓制工藝，如沖壓、彎曲、翻邊等。也可從事于校正、壓裝、砂輪成型、塑料制品、橡膠制品及粉末制品的壓制成型。

　　該系列產品主機采用三梁四柱式結構，液壓系統采用插裝閥油路，電氣系統采用繼電器或PLC控制電路，具備調整和半自動操作方式，整機結構簡單、緊湊、經濟合理，動作可靠，使用壽命長，液壓沖擊力小，減少了連接管路與泄漏。

　　四柱液壓機系列產品的工作壓力、壓制速度、行程范圍均可根據工藝需要在規定范圍內進行調整，可實現定壓和定程兩種工藝方式。定壓成型時，在壓制后有保壓延時及自動回程。工作臺中間裝有頂出裝置，除頂出制品外，尚可作為液壓墊用于把拉伸制件的成型工藝。

    可以選配前后自動機械輥道和機械手。

Use end and characteristics：
This series product applies to press techniques of various plastic materials, such as punching, bending, crimping, etc. Besides, it can also be used for amendment, pushing mounting, forming of grinding wheel, press forming of plastic, rubber and powder products.

The host machine of this series applies three-girder and four-pillar structure. The hydraulic system applies Cartridge Valve oil line. The electric system applies relay or PLC to control circuit. It has the adjustable and semi-automatic operation mode. The whole machine features simple and compact structure, economical and reasonable price, reliable operation, long-term life, slight hydraulic impact force and less connection pipelines and leakage.

The work pressure, press speed, stroke range of this series can be adjustable within the specific range according to technical requirements and process preset pressure mode and stroke mode. During the preset pressure forming, there is pressure maintenance delay and automatic return after the press. There is the knockouts device used as hydraulic cushion for forming of drawing products except for knocking out products.
