液压金属压块机设计

摘要

工业化初期由于盲目扩大生产，金属浪费现象严重，而回收利用较少，废金属对环境的污染与日剧增。随着我国经济增长方式由粗放型向集约型的转变和人们环保意识的增强，市场对废金属处理的设备需求将越来越大。为了实现对废金属的有效回收，以及再利用，对有效处理废金属的压块机研究已引起了众多人的兴趣。

该液压废金属压块机用于常态下冷压各种厚度在3mm以下的废金属边角料，废钢屑，废油箱，解体汽车壳等金属废料。冷压成块状，便于储运或投炉。本机带有快送装置，大幅度提高工效。

该液压废金属压块机是集液压控制和电气控制为一体，液压缸在侧压板上的按照均布对称布置，以此实现了液压缸推动压板做圆弧形轨迹的运动。并且整个压块机由液压缸顺序动作推动压板、压头，提升门，实现了动作的一贯连续性。

该压块机的设计参数：料箱尺寸：2000*1000*500mm

压块尺寸：500*500*300

公称压力：1000KN

液压系统压力：25MPa

该液压废金属压块机体积小，操作方便，不但具备多种使用要求，而且大大提高了废金属回收的效率。

Abstract

Since the early industrialization blind expansion of production, metal waste are serious and less recycling, scrap metal pollution to the environment become more and more serious. As China's economic growth mode from extensive to intensive changes and the enhancement of environmental awareness among the people, the market for scrap metal processing equipment demand will grow. In order to achieve the effective recovery of scrap metal and re-use, effective handling of scrap metal on the Press has aroused the interest of many people.

The Hydraulic Press for scrap metal under the norm in the 3mm thickness of cold-pressing all kinds of the following bits and pieces of scrap metal, steel scrap, waste oil tanks and the disintegration of the shell and other metal scrap car. Cold into a massive, easy storage and transportation or to vote furnace. Local delivery devices with a fast, substantial increase in work efficiency.

Hydraulic Press scrap metal made metal-hydraulic control and electrical control as one. The hydraulic cylinder in the side clips on the uniform in accordance with the symmetrical layout, to achieve a hydraulic cylinder clips to promote the arc-shaped path of movement. and the entire sequence by the hydraulic cylinder action to promote clips, the pressure head, doors make the movement's continuity.

The Press of the design parameters: feed box size: 2000*1000*500mm Press Size: 500*500*300Nominal pressure: 1000KN Hydraulic system pressure: 25MPa

This hydraulic scrap metal Press has small size, it is easy to operate, not only meets the requirements of multiple use, but also greatly improves the efficiency of recycling scrap metal. Keywords：Hydraulic，Scrap metal，Press，Recycling
