A method for forming a profiled plate and its forming equipment

Abstract

The invention discloses a contour plate molding method and equipment. The molding method includes the following steps that contour plate panels are taken; extrusion molding is carried out through an extrusion molding machine from the middle portions of the panels to the two sides of the panels, and the two side edges of each panel are kept to extend outwards; and the two side edges of each panel obtained after extrusion molding are manufactured into lap joint tongue-and-groove structures through tongue-and-groove shaping equipment on a construction field. According to the contour plate molding method and equipment, an off-line manner is adopted, the contour plate panels are firstly subject to plate face molding treatment, the needed plate face cross section shape is obtained, the two side edges of the contour plate panels are not subject to tongue-and-groove manufacturing, the pre-molded contour plate panels are transported to the construction site, and independent tongue-and-groove manufacturing is carried out through the tongue-and-groove shaping equipment; by means of the manufacturing method, the plate face extrusion stress can be effectively released; and meanwhile, the condition that during loading, a gap exists between every two adjacent contour plates, the transportation number of contour plate panels and the surface flatness of the contour plate panels in the transportation process are influenced can be avoided.

Description

technical field [0001] The invention relates to the technical field of profiled plate forming, in particular to a profiled plate forming method and forming equipment thereof. Background technique [0002] At present, for the 350-type profiled plate, one-time extrusion is usually used to make the plate one-time extrusion formed into the structural form in use, and the extrusion forming method used is to extrude the two sides of the plate toward the middle, extruding The surface of the profiled plate formed after pressing will have unevenness, which will affect the appearance quality of the product; at the same time, in the one-time forming process, the various stresses on the plate cannot be released in time, resulting in the overlap of the groove and groove. A certain degree of deformation will also occur. Therefore, when the two profiled plates are connected, it will bring greater difficulties to the construction personnel and affect the construction efficiency. [0003] I...

Problems solved by technology

[0002] At present, for the 350-type profiled plate, one-time extrusion is usually used to make the plate one-time extrusion formed into the structural form under the use state, and the extrusion forming method adopted is to extrude the two sides of the plate toward the middle, extruding The surface of the profiled plate formed after pressing will have unevenness, which will affect the appearance quality of the product; at the same time, in the one-time forming process, the various stresses on the plate cannot be released in time, resulting in the overlap of the groove and groove. A certain degree of deformation will also occur. Therefore, when the two profiled plates are connected, it will bring greater difficulties to the construction personnel and affect the construction efficiency.

[0003] In addition, the profiled plates of this structure also face many problems during transportation. When stacking multiple formed profiled plates, the grooves on both sides of the upper and lower formed plates cannot form an effective lap, which will cause There is an overhead gap between the two profiled plates, which not only affects the loading quantity for transportation, but also deforms the surface of the plate for long-distance transportation, resulting in a greatly reduced yield
