Die Group and Technology for Stamping Forming of Building Formwork Steel Components

Abstract

The invention discloses a die set and process for stamping formwork steel members, and belongs to the technical field of formworks. The die set is characterized in that a die set for stamping is utilized to stamp an F type strip produced through hot rolling and straightening; the die set comprises a first stamping die and a second stamping die; a first stamping upper formwork assembly and a first stamping lower formwork assembly are connected through longitudinally corresponding first stamping guide posts (3); first stamping upper blades (13) are arranged among the first stamping guide posts (3); a second stamping upper formwork assembly and a second stamping lower formwork assembly are connected through second stamping springs (25) in a supporting manner; second stamping upper blade rods (18) are arranged in front and rear of the second stamping upper formwork assembly, and the outer sides of the lower ends of the second stamping upper blade rods (18) are fixed with second stamping upper blades (19). The obtained component is accurate in sizes of hole spacing and is stable in quality. When a formwork is welded, hole spacing dislocation is avoided, fitting in assembly process is accurate and quick, and engineering quality and construction efficiency are improved.

Description

technical field [0001] The invention relates to a mold group and a process for stamping forming of building formwork steel components, belonging to the technical field of building formwork. Background technique [0002] Existing building formwork mainly includes steel formwork, wood formwork and plastic formwork. Although wood formwork is easy to obtain, it has low rigidity, is easily damaged, cannot be used repeatedly for a long time, and has the obvious disadvantage of slow assembly speed. The steel formwork can be used repeatedly for a long time because of its high strength, but because the surface of the steel formwork does not absorb water, the surface of the concrete structure is not smooth and clean, and honeycomb phenomenon will occur, which seriously affects the construction quality. defect. Plastic formwork has the advantages of light weight and convenient use, but it is easy to age, and if it is partially damaged, it will be scrapped as a whole. The surface of th...

Problems solved by technology

However, the structure of the steel mold frame of this formwork is relatively complicated, and punching holes need to be punched in multiple places. It is difficult to produce a steel mold frame with a unified structure by using traditional technology, which makes it difficult to cooperate between the formwork. Specifically, there are the following problems:

[0003] 1. From the technical point of view, it is troublesome to use a punching die for the insertion groove, the cost is high, the yield is low, and the product quality is unstable due to large stamping burrs

[0004] 2. From the perspective of the mold, there are many holes in the formwork structural parts. At present, domestic manufacturers use single-hole or 2-3 hole molds for stamping. It takes several punches to complete a component, which is labor-intensive and time-consuming, and the production efficiency is low. Hole spacing error is large

[0005] 3. In terms of product quality, because the hole spacing on the components cannot be guaranteed, the dislocation of the hole spacing will cause the working surface after the formwork is assembled to be uneven during the on-site construction process after welding into the formwork, and the surface of the punched concrete will be uneven. Unevenness directly affects the quality of construction projects
