What is the working principle of the heat press

With the reduction of wood, more and more stickers, stickers and other stickers are used on furniture. Heat presses are often used in veneer and wood-based panel woodworking machinery parts in furniture manufacturing. Their production capacity and technical performance restrict the production of enterprises. Pros and cons of scale and product quality.

1. Hydraulic system process requirements

There are two substrate work requirements for thermocompressive hydraulic systems. That is, in order to perform a specific movement, pressure must be applied to the workpiece or a hot plate actuated. Rapid shutdown and compression stability are important indicators for evaluating hydraulic system performance. For the veneer, the heating and curing of the adhesive must be carried out in the compression connection section, so the polishing speed is beneficial to the process and efficiency, reducing the heating of the substrate under non-pressure, preventing the surface of the substrate from dehydration, preventing warping, and preventing pre-curing of the adhesive Reduce the quality of veneer. On the other hand, it can shorten the auxiliary time and improve the productivity of the press. To soften the switches of the presses, machine synchronizers or hydraulic systems are often used to keep them in sync.

2. Hydraulic cylinder

The hydraulic cylinder is the central part of the hydraulic system and most woodworking presses today use plunger hydraulic cylinders. Large diameter cylinder plunger hydraulic cylinder. The large-diameter cylindrical plunger is cast with an alloy that is superior in hardness, hardness layer thickness, scratches, and performance to carbon steel heat-treated plungers. Small-diameter cylinder plunger, carbon steel hot-pressed surface hard chrome plating base point, surface hardness layer is thin. High-strength materials must be selected for the cylinder, because fast switching frequencies and shocks are usually required. The same small-diameter, long-stroke hydraulic cylinders can be made into smooth thick-walled tubes, and all cylinders with relatively high requirements can choose casting or forging cylinders. Generally speaking, the workbenches of hot presses for wood processing and furniture manufacturing are relatively large. For uniform pressure distribution and considering the rationality of construction layout, most of them adopt cylinder structure.
