A manufacturing process of an integrated water jacket heating plate for a large plate hot press

Abstract

Disclosed is a manufacturing process for an integrated water jacket heating plate of a big-plate hot press. A whole steel plate is horizontally put on a machining platform of a G38L accurate deep hole boring machine, horizontal circulation channels are formed through drilling, a drill bit performs machining according to the marked positions of corner channels, and S-shaped circulation channels are formed in the whole steel plate; stop blocks are welded and fixed in the corner channels through electric welding; two head sealing plates where observing and cleaning holes are drilled are welded and fixed to the two ends of the whole steel plate; the peripheries of choke plug screws are wrapped with sealing gaskets and the choke plug screws are arranged in the observing and cleaning holes in a screw joint mode; and the water jacket heating plate is formed after the above steps are finished. The heat efficiency of the water jacket heating plate is greatly improved; scrapping of traditional water jacket heating plates due to the fact that deposited dirt blocks the S-shaped circulation channels is effectively avoided; and the heat efficiency is not reduced even in the whole service life of the water jacket heating plate, moreover, the water jacket heating plate is firm and durable and cannot be damaged in the whole service life, the whole heat transmission reliability and stability of an equipment heating circulation system are greatly improved, and the service life of the equipment heating circulation system is greatly prolonged.

Description

technical field [0001] The invention relates to large plate hot press equipment, in particular to a manufacturing process of an integrated water jacket heating plate for a large plate hot press. Background technique [0002] At present, the overall heating system used on large-plate hot presses is composed of one or two or more than two water jacket heating plates. The water jacket heating plate is made by welding steel plates and steel strips or steel plates and square tubes. The interior of the welded water jacket heating plate is composed of a number of S-shaped circulation channels. The heated water or heat transfer oil circulates through the welded water jacket heating plate to make the water jacket heating plate reach the temperature required by the user. However, the welded water The jacket heating plate is easy to deform and leak water. After long-term use, the surface of the circulation channel in the water jacket heating plate is easy to deposit dirt to block the c...

Problems solved by technology

[0002] At present, the overall heating system used on large-plate hot presses is composed of one or two or more than two water jacket heating plates. The water jacket heating plate is made by welding steel plates and steel strips or steel plates and square tubes. The interior of the welded water jacket heating plate is composed of a number of S-shaped circulation channels. The heated water or heat transfer oil circulates through the welded water jacket heating plate to make the water jacket heating plate reach the temperature required by the user. However, the welded water The jacket heating plate is easy to deform and leak water. After long-term use, the surface of the circulation channel in the water jacket heating plate is easy to deposit dirt to block the circulation channel, causing the circulation channel of the entire water jacket heating plate to be blocked. The dirt deposited on the inner wall of the circulation channel in the early stage of blockage will cause Reduced heat conduction efficiency, high energy consumption, and increased operating costs. The existing water jacket heating plate does not have observation holes or cleaning holes. In the later stage of blockage, the circulation channel is completely blocked and cannot be cleaned, resulting in the overall scrapping of the water jacket heating plate, causing huge economic losses to users.
