Embodiment 1

[0024] The production process of the steel grating is proposed, including the following steps:

[0025] S1, slotting:

[0026] Fix several longitudinal strips 1 on the fixture in order, and cooperate with several longitudinal strips 1 through the fixture, so that all the longitudinal strips 1 are as close to parallel as possible, and then use the slotting tool to open the same number of slots on each longitudinal strip 1 11, see figure 1 , wherein the groove 11 has a width of L1 and a depth of H1.

[0027] S2. Embedding:

[0028] A cross bar 2 is embedded in a corresponding groove 11 on all the above-mentioned longitudinal bars 1, wherein the cross bar 2 is made of flat steel. see figure 2 , the thickness of the bar 2 is L2, and the height is H2. Where: L1>L2, H1

[0029] That is to say, after the crossbar ...

Abstract

The invention discloses a steel grating plate production process, which comprises the following steps of grooving: a plurality of longitudinal strips are fixed, and a plurality of grooves are formed on the longitudinal strips; embedding: a transverse rod is embedded into the grooves, the transverse rod is embedded into the groove of one longitudinal strip, the depth of the groove is smaller than the height of the transverse rod, and the width of the groove is greater than the thickness of the transverse rod; pressure welding: the transverse rod and the groove are welded by an electric resistance welding method, and in addition, the upper surface of the transverse rod and the upper surface of the longitudinal strips are flatly pressed when the welding position of the transverse rod and the groove is still in a high-temperature state; repeated embedding and pressure welding: the welding of the next transverse rod is completed, the many-time repeated embedding and the pressure welding are carried out until the welding between the transverse rod and the grooves is completed, and a steel grating plate is formed; cuttings: the steel grating plate is cut into steel grating plate units; end plate welding: the end surface of the transverse rod and the end surfaces of all longitudinal strips are welded with an end plate, and a steel grating plate finished product is formed; and zinc plating: the steel grating plate finished product is subjected to zinc plating treatment. The energy is saved, the production is easy, and in addition, the requirements on raw materials and processing equipment are lower.

Description

technical field [0001] The invention relates to a production process of a steel grating. Background technique [0002] At present, steel grating products are mainly divided into pressure-welded steel grating and pressure-locked steel grating according to different production methods. Among them, the cross bar of the press-locked steel grating is usually made of flat steel, and each intersection point of the load-bearing flat steel and the cross bar is pressed into the load-bearing flat steel by pressure at each intersection point during processing to fix it. Processing press-locked steel gratings in this way requires sufficient pressure on the processing equipment and complex tooling to complete, which not only consumes a lot of energy, but also requires extremely high equipment requirements, which needs to be improved urgently. . Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to propose a produ...
