Abstract
The invention relates to novel production technology for processing a protective guard surface on line. The novel production technology comprises the following steps of: mounting the steel strip on an uncoiling machine by using a charging machine; after uncoiling, carrying out a trimming process and a corner treatment process according to the specification of a guard board, polishing and cutting the square edge of a steel plate into an obtuse angle or a circular arc; punching according to the hole site and the size of the guard board; blasting the inner surface and outer surface of the steep plate, cleaning oxide skin, rust, welding slag, oil contamination and the like on the surface of the steep plate, wherein the derusting grade is Sa 2.5 grade; carrying out chemical processing processes, namely degreasing, washing, surface conditioning, phosphating and washing; and finally carrying out cold bending forming process, shearing process and then coating process. The novel production technology for processing the protective guard surface on line integrates forming process and surface processing process of the guard board, thereby shortening production line, improving production efficiency and ensuring product quality.
Description
Technical field
The present invention relates to a kind of metal surface treatment process, specifically is the production technology of a kind of novel protective guard surface online treatment.
Background technology
In recent years, China's speedway develop rapidly, the production and processing industry of guardrail board constantly enlarges, the production of traditional guardrail board is to produce guardrail board with steel band earlier, and through surfacing, last galvanizing by dipping is handled or the composite coating painting anticorrosion, it is independently operating procedure of three of the cold roll forming, surface preparation of guardrail board and applications, so not only make production line elongate, production process can not effectively integrate, and has influenced production efficiency greatly.
Summary of the invention
In order to solve operation independence in the guardrail board production technology, producing line length influences the problem of production efficiency, the invention provides the production technology of a kind of novel protective guard surface online treatment, this process integration the production line of protected apron, improved production efficiency greatly.
The present invention solves the technological process that its technical problem adopts: its technological process is: steel band uncoiling → side cut → corner processing → punching → ball blast → degreasing → washing → table accent → phosphatization → washing → cold roll forming → shearing → application.
Concrete steps are: choose steel band, utilize feeder that steel band is installed on the uncoiler; After the uncoiling according to the specification of guardrail board through the side cut operation, again by corner treatment process, with the right-angle side polishing of steel plate or cut into obtuse angle or circular-arc; Carry out punching according to the position, hole and the size of guardrail board again; Select 25～30 purpose shots for use, the surfaces externally and internally of steel plate is carried out Shot Blasting, the oxide skin of cleaning surface of steel plate, iron rust, welding slag, greasy dirt etc., derusting grade is to the Sa2.5 level; Carrying out the chemical treatment operation then is degreasing, washing, table accent, phosphatization, washing step; Via cold roll forming operation and cutting operation, enter coating process at last, this kind technological process is integrated greatly and is shortened the whole production line procedures, has improved production efficiency.
The invention has the beneficial effects as follows: the production technology of the novel protective guard of this kind surface online treatment is incorporated into the moulding process and the process of surface treatment of guardrail board together, has shortened production line, has improved production efficiency, has guaranteed product quality.
Specific embodiment
The present invention will be further described below in conjunction with specific embodiment.
Choose the hot rolled strip of 4mm thickness, utilize feeder that steel band is installed in uncoiling production on the uncoiler, dimensional requirement according to freeway guardrail is cut edge, by the corner treating apparatus right-angle side of steel plate is cut, the obtuse angle of cutting is 135 ° again, carries out punching then, clear up the surface of steel plate then with 25 purpose shots, remove surperficial oxide skin, iron rust, welding slag, greasy dirt etc., derusting grade is to the Sa2.5 level, again through degreasing, washing, table accent, phosphatization, washing step; Enter cold roll forming operation, cutting operation at last, promptly obtain the intact corrugated beam steeled protection fence plate of surfacing, directly enter coating process.
