Abstract
The invention discloses a compression joint technique for grid plates and steel grating plates, which comprises the steps of selecting longitudinal bearing plates, transverse connecting rods, and procedures of arrangement, insertion and forging. Since the technique employs the cold extrusion or cold forging method, the technique requires little electric energy and does not destroy the ambient environment. The prior production techniques for grid plates and steel grating plates, including cast soldering, press welding or other welding modes, require large consumption of electric energy. Meanwhile, cast soldering, press welding or other welding modes destroy the ambient environment, such as welding arc, welding spatter, discharge of cooling water, cast soldering dust, cast soldering waste gas, and the like.
Description
Technical field
The invention discloses the forging method of a kind of flase floor and steel grating.
Background technology
Along with economic development, flase floor and steel grating are in the application of industries such as oil, shipbuilding, building, digging, public way, the energy and decoration more and more widely.Traditional flase floor all adopts casting, pressure welding and other welding manners that cross bar is connected moulding with the longitudinal load-bearing flat bar with steel grating production, so energy consumption is bigger.Simultaneously, the investment of initial stage equipment input is also big.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of required electric energy little and the flase floor that surrounding environment is not damaged and the compression joint technique of steel grating.
According to technical scheme provided by the invention, the compression joint technique of described flase floor and steel grating comprises the steps:
A, selection offer some blocks of longitudinal load-bearing sheet materials of connecting hole, select the cross bar that is connected with described connecting hole cooperation;
B, some longitudinal load-bearing sheet material spaced and parallel are arranged, and the connecting hole that is in same area on the adjacent longitudinal load-bearing sheet material is positioned on the horizontal straight line; Insert in the connecting hole of arranging correspondence on the good longitudinal load-bearing sheet material connecting cross bar, and make the two ends that connect cross bar expose the most inboard and outermost longitudinal load-bearing sheet material;
C, described connection cross bar is exerted pressure, utilize to connect the plastic deformation that cross bar produces, will connect cross bar and longitudinal load-bearing sheet material is fixed together with crimp.
In step c, with crimp the connection cross bar between adjacent two longitudinal load-bearing sheet materials, the connection cross bar that is positioned at the connection cross bar of the most inboard longitudinal load-bearing sheet material inboard and is positioned at the outermost longitudinal load-bearing sheet material outside are exerted pressure, make to connect cross bar and on perpendicular to direction of exerting pressure, produce plastic deformation, the connection cross bar of plastic deformation perpendicular to the size on the direction of exerting pressure greater than connecting hole perpendicular to the size on the direction of exerting pressure.
The described mould of exerting pressure is forge die or extrusion die.
Because the present invention adopts the method for cold extrusion or cold forging, required electric energy is very little, and surrounding environment is not damaged.And no matter existing flase floor and steel grating production are casting, or pressure welding or other welding manners, all need a large amount of electric energy of loss.And casting, pressure welding or other welding manners all damage surrounding environment, as: the discharging of welding arc light, spatter, cooling water, casting dust, casting waste gas or the like.

The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
The compression joint technique of this flase floor and steel grating comprises the steps:
A, select to offer some blocks of longitudinal load-bearing sheet materials 1 of connecting hole 3, select with described connecting hole 3 cooperations be connected cross bar 2;
B, some blocks of longitudinal load-bearing sheet materials 1 are spaced, make the connecting hole 3 on all longitudinal load-bearing sheet materials 1 arrange the some straight lines of formation, insert in good longitudinal load-bearing sheet material 1 respective connecting 3 of arrangement connecting cross bar 2, make the two ends that connect cross bar 2 expose the most inboard and outermost longitudinal load-bearing sheet material 1;
C, the connection cross bar 2 of using forge die 4 to forge and press between adjacent two longitudinal load-bearing sheet materials 1, be positioned at the connection cross bar 2 of the most inboard longitudinal load-bearing sheet material 1 inboard and the connection cross bar 2 that is positioned at outermost longitudinal load-bearing sheet material 1 outside with forge die (or extrusion die) forging and pressing (extruding), forge die forging and pressing pressure is controlled at about 50 tons, make to connect cross bar 2 and on perpendicular to the forging and pressing direction, producing plastic deformation, the connection cross bar 2 of plastic deformation perpendicular to the size on the forging and pressing direction greater than connecting hole 3 perpendicular to the size on the forging and pressing direction.
Wherein connecting hole 3 is preferably square or rectangle, and at this moment, connecting cross bar 2 sections also is the square or the rectangle of coincideing with connecting hole 3 shapes.And connecting hole 3 preferably is the water chestnut shape to be offered, and promptly connecting hole 3 summit is higher than other three summits.
