Plastic composite tubular product sample cutting machine for steel wire gauze framework

Abstract

The invention discloses a plastic composite tubular product sample cutting machine for a steel wire gauze framework. A frame is provided with a fixture for clamping a plastic composite pipe of the steel wire gauze framework; a large wheel has a hollow cylindrical structure, is fixed on the frame through two groups of bearing devices, and is positioned at one side of the plastic composite pipe of the steel wire gauze framework; the central axis of the plastic composite pipe of the steel wire gauze framework is coincided with the central axis of the large wheel; a connecting part is connected with the large wheel into a whole through a connecting flange; a reducing motor is fixed on the large wheel or the connecting part, and is connected with a screw rod through a shaft coupling; the screw rod is fixedly connected with a guide post; a cutting motor is fixed on a cutting motor fixing plate; and a high-speed resin saw blade is connected with the cutting motor. The high-speed resin saw blade is taken as a cutting tool, so that cutting and grinding are completed synchronously, the efficiency is high; a steel wire is prevented from being broken by hooking, a steel wire in a sample is fixed, and the end face is smooth and even; and the entire set of equipment has low manufacturing cost and is easy to accept by small and medium-sized enterprises.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a steel mesh skeleton plastic composite pipe sample cutting machine. Background technique [0002] Steel mesh skeleton polyethylene composite pipe is a new type of high-tech and environmentally friendly chemical pipe that has emerged in China in the past ten years. It is based on a network structure formed by high-strength copper-plated steel wire winding and weaving left and right, with high-density polyethylene as the base material (polyethylene is a special material for PE100 grade pipes), and using modified polyethylene---adhesive resin, It is a new generation of chemical building materials with pressure resistance, internal and external anti-corrosion formed by continuous and step-by-step extrusion compounding on the production line. The product specification is φ63~φ630mm, widely used in municipal water supply and drainage, petrochemical, electric power, coal and mining industries. ...

AI Technical Summary

Problems solved by technology

However, there are several main disadvantages in cutting steel mesh skeleton plastic composite pipes by gantry-type band sawing machines; first, the saw blades of gantry-type band sawing machines are toothed band saws. The steel wire is broken and shifted by the sawtooth, which causes the arrangement of the steel wire in the section of the cut sample to be destroyed, and the prepared sample is scrapped; damage or even a danger to the personal safety of the operator

Second, although the end face of the steel mesh skeleton plastic composite pipe cut by the gantry band sawing machine is flat, it is not smooth, and there are many saw blade cutting marks visible to the naked eye, and the end face needs to be further polished

Third, the gantry-type band sawing machine is a relatively mature mechanical equipment on the market. It is mainly used to cut metal products such as steel. It has a complex structure, a large size, and high equipment manufacturing costs. For the production of sample tubes, the input-output ratio is not coordinated

However, the main disadvantages are, first: it is mainly made by hand, and the efficiency is low; second, the end surface of the produced sample is uneven and the quality is low
