Problems solved by technology

At present, the production of steel grating is mainly produced by large-scale professional welding equipment. When welding, first arrange the crossbar on the top of the flat steel, and then perform pressure welding on the crossbar to weld the crossbar and flat steel into shape. The welding equipment has complex equipment. Disadvantages such as high power consumption and large initial investment in equipment

Embodiment 1

[0069] Such as Figure 1 to Figure 5 , Figure 7 to Figure 10 As shown, a steel grating of the present invention includes a flat steel 1 and a cross bar 2, and each flat steel 1 is provided with two or more through holes 5, and in this embodiment, each flat steel 1 is provided with four Through holes 5, four through holes 5 are arranged at equal intervals. The through hole 5 is adapted to the outer wall of the cross bar 2 , that is, the cross bar 2 can only pass through the through hole 5 on the flat steel 1 . Each crossbar 2 passes through the corresponding through holes 5 of all the flat steels. In this embodiment, each crossbar 2 passes through eight flat steels 1 . Corresponding to the top of each through hole 5, there is an indentation groove 4 on the top of the flat steel 1. Under the downward transmission of pressure, the indentation groove 4 corresponding to the lower cross bar also deforms and forms an extrusion pit. A left bulge 8 and a right bulge 7 are respectiv...

Embodiment 2

[0073] Example 2 as Figure 11 to Figure 13 As shown, the indentation groove 4 is provided with a clamping groove corresponding to the lower cross bar, and the clamping groove is an annular groove 6 . The outer wall of the through hole 5 is snapped into the slot. Other structures are with embodiment 1. Due to the application of pressure, the outer wall of the through hole 5 is firmly clamped in the outer wall of the annular groove 6, so that the cross bar 2 can neither move nor rotate in the through hole. This structure can make the pressing pressure smaller than that of Embodiment 1 to realize the connection.

Embodiment 3

[0075] The steel grating of embodiment 3 is as Figure 14 to Figure 17 As shown, the clamping groove is an upper concave flat groove 10, the upper concave flat groove 10 is located at the top of the cross bar 2, and the outer wall of the through hole 5 is clamped in the clamping groove. Other structures are with embodiment 2. By applying pressure, the outer wall of the through hole 5 is firmly clamped in the upper concave flat groove 10, so that the cross bar 2 can neither move nor rotate in the through hole.

Abstract

The invention discloses a steel grating, a using device and a production method. The steel grating comprises flat bars and cross rods. Each flat bar is provided with a through hole, the cross rods penetrate through corresponding through holes of the flat bars, and an indentation groove is arranged at the top end of each flat bar. One portion of each indentation groove corresponding to the lower cross rod forms an extrusion pit, a left protrusion and a right protrusion are respectively formed on two sides of each extrusion pit, and the outer wall of the through hole of each flat bar is clamped between the left protrusion and the right protrusion; or one portion of each indentation groove corresponding to the lower cross rod is provided with a clamping groove and the outer wall of the through hoe of each flat bar is clamped in each clamping groove. The production device of the steel grating comprises a press head and a first slot template. The production method of the steel grating includes that: the through holes of the flat bars are processed; the flat bars are inserted into flat bar grooves of the first slot template; the cross rods penetrate through the corresponding through holes of the flat bars and are positioned through baffles; and a press provided with the press head exerts pressure at the top end of the through holes of the flat bars. According to the steel grating, the using device and the production method, large special welding devices are not needed, massive consumption of electric energy is saved, the manufacture cost is low and the process is simple and practical.

Description

technical field [0001] The invention relates to a steel grating and a production method thereof, belonging to the technical field of steel grating manufacturing. Background technique [0002] Steel grating, also known as grid plate, is a kind of steel product made of flat steel cross-arranged according to a certain interval and cross bars, and welded into a square grid in the middle. Steel grating is mainly used as a drain cover. Steel structure platform plate, step plate of steel ladder, etc. Steel grating is generally made of carbon structural steel, and the surface is hot-dip galvanized, which can prevent oxidation. It can also be made of stainless steel. The steel grating has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties. At present, the production of steel grating is mainly produced by large-scale professional welding equipment. When welding, first arrange the crossbar on the top of the flat steel, and then perform pressure we...
