Pipeline foam plastic outer layer rust removing and pressing integrated equipment

Abstract

The invention discloses pipeline foam plastic outer layer rust removing and pressing integrated equipment, and relates to the field of foam plastic machining equipment. The pipeline foam plastic outer layer rust removing and pressing integrated equipment comprises a pair of fixing blocks, a connecting bridge is connected between the tops of the pair of fixing blocks, multiple sets of mold assembly hydraulic jacks are arranged in the fixing blocks, and electric heating templates are arranged at the output ends of the mold assembly hydraulic jacks; and extrusion hydraulic jacks are arranged in the fixing blocks in a penetrating mode, linkage discs are arranged at the output ends of the extrusion hydraulic jacks, and extrusion sleeves matched with the linkage discs are arranged at the ends, close to the electric heating templates, of the linkage discs. The electric heating templates are pushed by the mold assembly hydraulic jacks to be matched with foam plastic outer layers and the extrusion sleeves which are completed firstly, at the moment, foam plastic particles are injected into cavities formed by the electric heating templates, the foam plastic outer layers and the extrusion sleeves through particle injection pipes, then the linkage discs are driven by the extrusion hydraulic jacks, and the extrusion sleeves are further driven to move towards the interiors of the electric heating templates; and therefore the foam plastic particles are extruded, the density of the foam plastic particles is improved, and the quality of finished products is further improved.

Description

technical field [0001] The invention relates to the field of foam plastic processing equipment, in particular to an integrated equipment for derusting and pressing the foam plastic outer layer of pipelines. Background technique [0002] Foamed plastics, also known as microporous plastics, are plastics that are covered with numerous interconnected or disconnected micropores that significantly reduce the apparent density. They have the advantages of light weight, heat insulation, sound absorption, shock resistance, moisture resistance, and corrosion resistance. The cell structure can be divided into closed-cell, open-cell and reticulated foams. All cells of closed-cell foams are almost disconnected, and all cells of open-cell foams are almost connected, and there are almost no cell walls. The foamed plastics are called reticulated foamed plastics. According to the density of foamed plastics, they can be divided into low-foamed, medium-foamed and high-foamed plastics. The diele...
