摘 要

本课题拟设计人造板自动横向贴面热压机，众所周知，人造板制造行业是一个高污染，高毒害的行业，所以能够自动的控制人造板的制造变得尤为重要，本体的良好设计为控制打好基础。该设计主要包括：框架板、热压板、油缸、同步机构的设计。本设计主要采用设计计算校核经验与选用论证为主。它主要研究控制油缸与热压板以保证热压机的压力、温度、压板平面度等。主油缸采用了柱塞缸的形式，因为柱塞缸的柱塞与缸筒无配合要求，缸筒内孔不需要精加工；设计良好的密封结构，采用优良的密封形式与导向机构以保证主油缸的良好工作环境；校核计算缸体厚度，以保证在高压的工作环境下，缸筒可以长时间的工作。采用双半法兰以保证柱塞与热压板的可靠、垂直联接；油缸与框架板的设计配合采用吊装螺纹孔联结。由于热压机需要提升的重力不大，采用活塞缸作提升缸。设计计算提升缸的缸径，以保证有足够强度能在13MPa的最大工作压力内安全的将热压板及8个主油缸提升起来。设计计算热压板的厚度，以保证不被压溃且不能太厚不能影响导热油的导热；采用横向三进三出的热压油孔流向布置以满足热压板的温度要求以及加工工艺的要求；分析孔口大小，以保证温度要求，这是此设计的重中之重。

Wood-based panels automatic hot press lateral total body design case and press

ABSTRACT

This paper intends to design artificial board automatic transverse veneer pressing machine, it is known, artificial board manufacturing industry is a high pollution, high toxic industries, it is possible to manufacture fully automatic control of wood-based panels has become particularly important, well-designed body to control a sound foundation. The design includes: a frame plate, hot plate, cylinder, synchronous mechanism design. This design uses the design calculation and selection argument based verification experience. It mainly studies the control cylinder and the hot plate to ensure that the pressure, temperature, pressure plate flatness of the pressing machine. Master cylinder takes the form of piston-cylinder, as the piston cylinder piston and cylinder with no requirements, the cylinder bore does not need finishing; good design seal structure, using good form and seal guide mechanism to ensure that the main good working environment cylinder; check the thickness of the cylinder calculated to ensure that the working environment at high pressure, the cylinder can be a long job. Semi-double flange plunger and to ensure reliable hot plate, vertical coupling; cylinder and frame plate design with the use of lifting screw hole coupling. Since the pressing need to upgrade gravity machine is not used for the lift cylinder piston cylinder. Design calculations lifting cylinder bore, to ensure sufficient strength can secure the hot plate and eight master cylinder lifted within the maximum working pressure of 13MPa. Thickness design calculations hot plate to guarantee not to be crushed and not too thick not affect the thermal conducting oil; use of horizontal three-three hole flow of hot pressing plate arranged to meet temperature requirements and processing technology requirements; analysis orifice size, temperature requirements to ensure that this is the top priority of this design.

Key words: veneer hot press; mechanical design; oil cylinder
