Description
Technical field
The present invention relates to the refrigerated container manufacturing, especially for the making of refrigerated container metal assembly, specifically is plate-shaped members and a kind of method of attachment between the plate-shaped members in the metal assembly.
Background technology
Refrigerated container is a kind of later-model freight container form, and the particular characteristics that this freight container can be used to refrigerate requires its part parts to have different method for makings with other freight containers.
As shown in Figure 1, be the welding scheme drawing between a kind of refrigerated container plate and the plate in the prior art, the butt joint welding face of this welding requirements sheet material 1 and sheet material 2 must fit tightly is in the same place, so the cutting of sheet material is required than higher.
As shown in Figure 2; It is the welding scheme drawing between another kind of refrigerated container plate and the plate in the prior art; Though this welding is the overlap joint welding; But the both sides up and down of sheet material 1 and sheet material 2 all need utilize the welding wire welding when welding generally speaking, thus bigger to the consumption rate of welding wire, increased productive costs.
In sum, in the middle of the existing refrigerated container manufacturing process, there is above-mentioned defective in the welding between plate-shaped members and the plate plate-shaped members, is further improved.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the above-mentioned prior art, a kind of manufacturing approach of new refrigerated container is provided, specifically is the method for attachment between the refrigerated container plate-shaped members.On the refrigerated container of the present invention in the metal assembly method of attachment between plate-shaped members and the plate-shaped members need the connecting portion between the two boards type spare not carried out accurate cutting; Do not need respectively the upper and lower both sides of two boards type spare to be welded with welding wire more yet; Intensity is high after connecting completion between the two boards type spare about making, on technology, also is easy to realize.
In order to reach the foregoing invention purpose, method of the present invention provides following technical scheme:
A kind of manufacturing approach of refrigerated container; This method comprise at least metal assembly manufacturing, assemble and interconnect process and foam filled process; Said metal assembly includes plate-shaped members, and following steps are adopted in the connection between said plate-shaped members, and this method overlaps the marginal portion of adjacent plate-shaped members earlier; Again overlap is positioned on the copper parts; Be pressed in the overlap of plate-shaped members then with a copper roller, this copper roller is connected to welding machine, utilizes the roll welding of copper roller to weld two boards type spare and links into an integrated entity.
In the method for making of refrigerated container of the present invention, this method comprises following detailed step:
1. when refrigerated container is made, earlier with adjacent on the freight container chassis, need overlap joint bonded assembly two boards type spare to be placed into respectively on the cooresponding shelf;
2. again the edge that needs connecting bridge between the two boards type spare is overlapped connection with the mode that superposes up and down; Respectively two boards type spare is fixed then; And the overlap of two boards type spare is positioned on the copper parts, the width of these copper parts is corresponding to the width of plate-shaped members overlap;
3. above overlap, compress, and this copper roller is connected with welding machine with a copper roller;
4. open welding machine, the logical high electric current of plate-shaped members overlapping portion being pressed between copper roller and the copper parts makes linking together through intermolecular ways of connecting between the binding face up and down of two boards type spare;
5. at the stack overlap of the two boards type spare said copper roller that rolls back and forth, utilize the roll welding of copper roller to accomplish the attended operation between the adjacent plate-shaped members in the metal assembly on two refrigerated containers.
In the manufacturing approach of refrigerated container of the present invention; Said copper parts are a copper bar; The width of this copper bar equals the width of plate-shaped members overlap, and length equals the length of plate-shaped members overlap, said copper bar when the copper roller rolls and the plate-shaped members overlap keep static relatively.
In the manufacturing approach of refrigerated container of the present invention, said copper parts are the copper roller, and this copper roller clamps said plate-shaped members overlap with the copper roller that is positioned at plate-shaped members overlap top, rolls back and forth at the plate-shaped members overlap simultaneously.
In the manufacturing approach of refrigerated container of the present invention, two adjacent plate-shaped members on the 1. middle refrigerated container of said step can be processed by commaterial, are perhaps processed by two blocks of close materials of fusing point.
In the manufacturing approach of refrigerated container of the present invention, the connection of adjacent plate-shaped members comprises the splicing of adjacent end wave plate in metal assembly, or being connected of end wave plate and goose neck tunnel girder, or being connected between the unrestrained plate in the end and the bottom cross beam.
Based on technique scheme, method of the present invention has following technological merit than the method for attachment between refrigerated container upper plate and the plate in the prior art:
1. method of the present invention belongs to tie welding; So just need the cutting of bonded assembly plate-shaped members connecting portion to reduce requirement to two; Also promptly higher to preceding road shear fabrication error tolerance, in manufacturing line, just the processing request to plate-shaped members in the last one procedure is reduced greatly.
2. method of the present invention belongs to a kind of overlap joint welding; Overlap joint is welded as the little material overlap joint of mother metal of the same race or fusing point difference, two plates or many plates is connected as a single entity accomplishes the fusion that relies on mother metal, so the height of the intensity after the welding and need not use welding wire fully; Its quality is improved, and welding cost reduce.
3. the frock that overlap joint roll welding of the present invention is suitable for automation requires low, on technology, realizes easily, efficiently solves high, the cost problem of higher of manufacturing process requirement when welding between existing refrigerated container upper plate and the plate.
