The wooden tray and the plastic tray are most widely used at the present stage, the wooden tray is low in cost and simple to manufacture, a plurality of wood boards are fixed into a frame structure through connecting pieces such as iron nails and the like, but the wooden tray is poor in performance, short in service life, and low in structural stability after a long time, or the connecting pieces fall off and are damaged, in addition, solid wood is generally adopted to achieve the required strength, the weight is generally heavier, and the transportation is not facilitated; the plastic tray is generally designed by integral molding, has high manufacturing cost and is not beneficial to environmental protection, the strength of the thinner plastic of the plate can not meet the use requirement, and the weight of the thickened plate is too heavy; at present, a small number of trays are made of metal materials, the metal materials are high in strength, most trays are formed by welding light hollow pipes, the number of required welding points is too many, the manufacturing efficiency is low, and the condition that welding points are not firm often occurs.

Therefore, the problem to be solved in the art is to provide an ultra-light metal profile tray which is light in weight, high in strength and simple to manufacture.

[ Utility model ] content

Aiming at the problems, the light metal section is formed by adopting a metal material through a bending process, and compared with the traditional wooden tray, the light metal section has high strength, stable structure and difficult deformation and can be repeatedly used; compared with a plastic tray, the plastic tray has the advantages of light weight, high strength, low manufacturing cost and environmental protection.

In order to solve the problems, the utility model provides an ultra-light metal section tray which is formed by welding a plurality of metal sections according to actual use requirements, and is divided by welding points, wherein the metal section above the welding points is an upper plate, and the metal section below the welding points is a lower plate; the metal section is of an axisymmetric bow structure after being bent, the upper plate and the lower plate of the metal section formed after bending are similar in structure and respectively comprise a plurality of transverse plates and vertical plates, the transverse plate positioned above is bent to form a plurality of upward convex upper small ribs, the transverse plate positioned below is bent to form a plurality of downward convex lower small ribs, and the upper small ribs and the lower small ribs are connected with the plurality of metal sections through resistance welding.

Furthermore, the transverse plates and the vertical plates are connected end to end, and the adjacent transverse plates and the adjacent vertical plates are perpendicular to each other.

Furthermore, two ends of the metal section bar are bent inwards to form a right angle or an arc.

Furthermore, the cross sections of the upper small rib and the lower small rib are arc-shaped arch structures.

Moreover, the metal material is adopted to form the light metal section through the bending process, and compared with the traditional wooden tray, the light metal section has high strength, stable structure and difficult deformation and can be repeatedly used; compared with a plastic tray, the plastic tray has the advantages of light weight, high strength, low manufacturing cost and environmental protection.

[ detailed description ] embodiments

The directional terms of the present invention, such as "up", "down", "front", "back", "left", "right", "inner", "outer", "side", etc., are only directions in the drawings, and are only used to explain and illustrate the present invention, but not to limit the scope of the present invention.

Referring to fig. 1 to 3, the composition structure of the ultra-light metal profile tray of the present invention is shown, the ultra-light metal profile tray is formed by welding a plurality of metal profiles according to actual use requirements, and is divided by welding points, the metal profile above the welding points is an upper plate 1, and the metal profile below the welding points is a lower plate 2; the ultra-light metal section is galvanized sheet, aluminized zinc plate or stainless steel material and forms through the preparation of bending process, the metal section bends the back and is axisymmetric bow line structure, upper plate 1 and hypoplastron 2 structure that the metal section formed after bending are similar, all include a plurality of diaphragm 3 and riser 4, diaphragm 3 and riser 4 end to end and adjacent diaphragm and riser mutually perpendicular, the both ends of metal section inwards form the right angle and bend or the arc is bent with this and avoids fish tail people or article, the diaphragm that is located the top bends out a plurality of little muscle 5 on the bellied upwards, the diaphragm that is located the below bends out a plurality of little muscle 6 under the bellied downwards, the cross section of upper and lower little muscle is circular-arc domes.

When upper plate 1 and hypoplastron 2 weld, two welding faces that contact must have last little muscle 5 or little muscle 6 down, noncontacting face can have little muscle also can not have little muscle, the lower surface of upper plate 1 has little muscle 6 down, the upper surface of hypoplastron 2 has last little muscle 5, little muscle 6 and last little muscle 5 contact down and form the welding point, when welding, upper plate 1 and hypoplastron 2 intercrossing, through heavy current (resistance welding) in the twinkling of an eye between upper plate and hypoplastron, turn into heat energy with most electric energy between the little muscle 6 of lower of upper plate and the last little muscle 5 of hypoplastron, make little muscle and little muscle junction melt the welding down, with this with many metal section bar welding into the tray of required size and shape.

The metal material is adopted to form the light metal section through the bending process, and compared with the traditional wooden tray, the light metal section has high strength, stable structure and difficult deformation and can be repeatedly used; compared with a plastic tray, the plastic tray has the advantages of light weight, high strength, low manufacturing cost and environmental protection.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
