Board hot pressing device

Abstract

The invention discloses a board hot pressing device. The board hot pressing device comprises a hot press body. The hot press body is composed of a press frame and a hot pressing cavity. The front side faces of two support legs of the press frame are each provided with at least one gradient positioning groove, the bottom of the hot pressing cavity is fixedly provided with a hydraulic oil cylinder drive system, a bottom pressing board is fixed to the upper end of the hydraulic oil cylinder drive system, at least one set of hot pressing steel boards are arranged on the bottom pressing board, the bottom of each hot pressing steel board is provided with bent flat iron stretching to the front side end of the hot pressing steel board, steel angles with the lengths sequentially reduced are fixedly welded to the two side ends of each set of hot pressing steel boards, and each steel angle corresponds to a press lug of the corresponding gradient positioning groove. The two side ends of the hot press body are each provided with a two-time circulation conduction oil system, and two sets of heat conduction coil pipes are arranged in each hot pressing steel board. One-time circulation conduction oil systems are improved into the two-time circulation conduction oil systems through the hot pressing device, the temperature of the hot pressing steel boards can be quickly increased, the hot pressing steel boards are evenly heated, cold oil in the hot pressing steel boards can be quickly pressed outside, and the boards are hot-pressed at high efficiency and high quality.

Description

technical field [0001] The invention relates to the field of plate processing equipment, in particular to a plate hot-pressing equipment. Background technique [0002] The board is usually made into a flat rectangular building material board of a standard size, which is used as a component of the wall, ceiling or floor. Material, sanding, painting and other steps, in the above-mentioned hot pressing steps, the effect of the hot pressing of the board directly affects the forming quality of the board, therefore, the hot pressing of the board is a relatively important step in the processing of the board, and in the prior art The heat transfer oil circulation system used in plate processing generally adopts a single cycle, that is, the oil is fed into the upper end of the hot-rolled steel plate, and the oil is discharged from the lower end of the hot-pressed steel plate. The single heat transfer oil system has the following disadvantages for heating the steel plate: First, for...

Problems solved by technology

[0002] Boards are usually made into flat rectangular building material boards of standard size, used as components of walls, ceilings or floors, and board processing is generally divided into marking, gluing, and veneering , cold pressing, hot pressing, trimming, back groove opening, material cutting, sanding, painting and other steps. The pressing link is more important in the plate processing steps. The heat transfer oil circulation system used in the plate processing in the prior art generally adopts a single cycle, that is, the oil is fed into the upper end of the hot-rolled steel plate and the oil is discharged from the lower end of the hot-pressed steel plate. , the heating of the steel plate with a single heat transfer oil system has the following disadvantages: first, the heating of the hot-pressed steel plate is not uniform enough, so that the surface or bottom skin of the formed wood board may be warped, and the board surface is upturned, which affects the processing quality of the board; secondly, the single The secondary cycle increases the heat output of the boiler room and consumes energy; thirdly, the existing single-cycle heat transfer oil system adopts the overall heating method. If a hot steel plate fails during the actual hot pressing process, the machine needs to be stopped. Carry out maintenance, reduce the efficiency of hot pressing, prolong the processing time of the sheet metal, and roughly interrupt the entire sheet processing system
