Winding type circular template and production device of winding type circular template

Abstract

The invention relates to a winding type circular template and a production device of the winding type circular template. The winding type circular template is of a cylindrical structure with a plurality of layers of wood veneers winding, and the multi-layer wood veneers are in composite bonding; each layer of wood veneer comprises a transverse grain wood veneer and a longitudinal grain wood veneer; the transverse grain wood veneers and the longitudinal grain wood veneers are in composite bonding, and the wood veneer seams at the joints of the transverse grain wood veneers and the longitudinalgrain wood veneers are uniformly distributed in the circumferential direction of the template; and compared with a semicircular template in the prior art, the circular template with the multi-layer cylindrical structure has the advantages of being reasonable in structure and high in stability, and the problems that for the semicircular template, the inner stress is not sufficiently released, the template is hard to store for a long time, and can be greatly influenced by the external environment, and the rejection rate remains high are solved. The circular template with the multi-layer cylindrical structure has the advantages of being not prone to deformation, easy to store, free of deformation and the like; and the qualified rate of finished products is improved, the processing cost is reduced, the yield is improved, the energy loss is reduced by adopting a natural drying and sizing method, and the economic benefits are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of mold processing, and in particular relates to a winding-type circular formwork and a production device for the winding-type circular formwork. Background technique [0002] At present, the templates processed in the prior art are all semicircular. It is necessary to make a plywood with a certain thickness first, and then cut the plywood according to the size of the semicircular template, (wherein a large amount of corner cuttings are generated to cause waste. ). At present, the processing of the semi-circular formwork adopts the following processing equipment and technology: 1. Apply glue evenly to the cut three-ply board, place multiple layers on the variable steel plate according to the thickness requirements, and hoist the cylindrical steel core Go above the veneer until it fits closely with the veneer; 2. Fix and hang the lanyards on both sides of the deformable steel plate on the cylindrical steel c...

Problems solved by technology

[0003] Although the above-mentioned processing device and process can produce templates according to the size of the mold cylinder, since the curved veneer mold is formed into an arc shape by strong pressure during the processing process, although the drying and heating setting process is adopted, there are still gaps inside. Large internal stress, so after long-term
