Embodiment Construction

[0026] Referring to Fig. 3, the stabilizing processing method of the roll shaft of the continuous press machine for wood-based panels, plastic panels and rubber panels of the present invention is that the raw material is a bar of medium carbon steel or high carbon steel, which is processed into a ratio roller through annealing and cold drawing. Shaft the workpiece with a diameter of 0.2mm to 0.4mm larger than the final product; then perform machining, quenching, and tempering heat treatment on the workpiece; then, rough grind the workpiece until the diameter of the roller shaft is larger than the final product 0.1mm~0.2mm; then, use a special container to stabilize the workpiece, set the temperature at 280°C~320°C, and set the time at 50~70 minutes to reduce the surface hardness to HRC45~55, and the internal structure Stable; finally, the workpiece is finely ground to make it meet the final product requirements of the roller shaft.

[0027] The above-mentioned quenching and te...

Abstract

The invention relates to a method for stabilizing the artificial plate, plastic plate, and rubber plate continuous compressor roller, wherein it uses the rod made from middle carbon or high carbon steel, via anneal and cold drawing, to be processed into the work piece with 0.2-0.4mm larger than the diameter of final roller; then mechanically processing, annealing and quenching the work piece; grinding the work piece to be 0.1mm-0.2mm larger than the final roller; using special container to stabilize the work piece; setting temperature at 280-320Deg. C, and setting time at 50-70min, to reduce the surface rigidity to HRC45-55, to stabilize the inner organism; then grinding the work piece. With said invention, the roller can resist 5mMPa pressure, without deformation at 250Deg. C and reduced surface rigidity.

Description

technical field [0001] The present invention relates to a continuous press for producing wood-based panels, plastic panels, and rubber panels, and relates to roller shafts used in the continuous press, and in particular to a process for stabilizing the rollers of the continuous presses for wood-based panels, plastic panels, and rubber panels. . Background technique [0002] Wood-based panels are boards made of non-natural wood. It is made of shavings, sawdust or wood chips mixed with glue at high temperature and then pressed under high pressure. It is currently the main material in the domestic furniture industry and decoration industry. [0003] As shown in Figures 1 and 2, the pressing parts of the wood-based panel continuous press mainly include an annular stainless steel plate 3, a roller shaft 2 arranged in the annular stainless steel plate 3, and the two ends of the roller shaft 2 are provided with pin holes 21 for installation. The mixed material 1 mixed with shaving...
