Abstract
The invention relates to a manufacturing method of an end wall of containers, including the following steps: a corner post, an upper beam and a lower beam are welded to form an end wall frame; two or more than two group plates forming an end wall plate are welded and connected together by a technology plate to form a blank plate of the end wall; a clearance is reserved between the group plates; the blank plate of the end wall is welded inside the end wall frame; then the group plates on the blank plate of the end wall are welded at the clearance between the group plates by dual-surface welding. Since welding of the group plates of the end wall is carried out after the blank plate of the end wall is welded on the end wall frame, the clearance between the group plates on the blank plate of the end wall generates welding shrinkage, thus removing the wave deformation generated by welding the blank plate of the end wall on the end wall frame, thus effectively controlling the welding deformation of the end wall plate, decreasing the internal stress on the end wall plate, remarkably increasing the strength, and requiring no other auxiliary facilities during the work implementation.
Description
Technical field
The present invention relates to the making of freight container, more particularly, relate to a kind of container end wall manufacturing method.
Background technology
Freight container has just developed into a kind of international transportation means of multimetering transport in the sixties in 20th century as the instrument of shipping.In the freight container field, regular general cargo general-duty dry cargo container because applicability is strong, and is able to widespread use.
For satisfying the needs of international combined transport, international standard has all been set clear and definite scope to the outside dimension of general-duty dry cargo container and the intensity of main components, therefore for the dry cargo container that outside dimension is determined, want to increase between its stacks of cargo emptying, must start with from the framing member that constitutes its inner space.The inner length of dry cargo container connects hexahedral length dimension in its inner space, usually be calculated as medial surface from the medial surface of door structure to headwall, under casing external width and height unmodified situation, this inner length defines the size between stacks of cargo emptying; Since the occupied casing length of door structure and headwall belong to can't stack goods " useless length ", reduce these " useless length ", can increase between stacks of cargo emptying, this can bring huge economic implications.
As shown in Figure 1, 2, in the present general dry cargo container, end wall panel 10 is welded in the headwall frame that is made of entablatrance 11, cross sill 12 and corner post 13 and forms described headwall.Wherein said end wall panel 10 adopts corrugated plating, it is too many that this corrugated plating of one side takies casing length, cause the waste of usage space, corrugated plating is when being subjected to the load that box house passes on the other hand, its wave crest, wave base and be connected angle generation obvious variation between the inclined-plane of wave crest, wave base, this variation is difficult to recover, and causes freight container that permanent deformation bigger, that be difficult to recover takes place thus, and later use is caused harmful effect.
Consider and adopt corrugated plating to make many deficiencies that end wall panel exists, occurred in the industry replacing corrugated plating to make the design direction of end wall panel with flat board, but in the practice, reason owing to the technology making, maturation is applied to flat end wall panel in the production and adopts the mode that back of the body beam is set on the side within it to make it reach requirement of strength usually, and the existence of back of the body beam makes freight container still have bigger " useless length ", can not increase the free space in the casing effectively, end wall panel is prone to bigger wave transformation simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is that at the above-mentioned defective of prior art, providing a kind of can increase the internal container loading space, can effectively prevent the container end wall manufacturing method of wave transformation again.
The technical solution adopted for the present invention to solve the technical problems is: a kind of container end wall manufacturing method is provided, may further comprise the steps:
S1, corner post, entablatrance, cross sill assembly welding are become the headwall frame;
S2, two or more than two the group plate that will constitute end wall panel link together with board spot welding and make the headwall blank flat, are reserved with the group sheet separation between the described group of plate;
S3, the headwall blank flat that S2 is made are welded in the frame of the headwall frame that S1 makes, and change step S4 over to;
S4, the group plate of described headwall blank flat is welded at group sheet separation place.
In container end wall manufacturing method of the present invention, weld from both sides is adopted in welding described in the described S4 step between the group plate of headwall blank flat, and the overlap that forms when polishing weld by the front earlier, carries out reverse side again and welds.
In container end wall manufacturing method of the present invention, described S3 step may further comprise the steps:
S3-1, the headwall blank flat that S2 is made are placed in the frame of the headwall frame that S1 makes and carry out spot welding;
Edge and headwall blank flat on S3-2, parallel group of sheet separation direction of elder generation's welding;
S3-3, weld edge and headwall blank flat on the direction of orthogonal sets sheet separation again.
In container end wall manufacturing method of the present invention, when carrying out spot welding in the described S3-1 step, guarantee that described headwall frame is reserved with welded gaps between edge on the direction of vertical described group of sheet separation and headwall blank flat.
In container end wall manufacturing method of the present invention, the welded gaps described in the S3-1 step is set to 2-4mm.
In container end wall manufacturing method of the present invention, the parallel described corner post setting in the group sheet separation described in the S3-1 step.
In container end wall manufacturing method of the present invention, the vertical described corner post setting in the group sheet separation described in the S3-1 step.
In container end wall manufacturing method of the present invention, the group sheet separation described in the S2 step is set to 3-6mm.
In container end wall manufacturing method of the present invention, also can be provided with reinforced rib on the group plate described in the S2 step, this reinforced rib can make by compacting or welding process.
In container end wall manufacturing method of the present invention, the height of described reinforced rib is set to 1-10mm.
Implement container end wall manufacturing method of the present invention, has following beneficial effect: in the method, because after the headwall blank flat is welded to the headwall frame, carry out the welding between end wall panel group plate again, the group sheet separation of headwall blank flat produces welding and shrinks, thereby eliminate the wave transformation that produces when being welded on the headwall blank flat on the headwall frame, not only controlled the welding deformation of end wall panel effectively, and the internal stress of end wall panel reduces, make its intensity be improved significantly, and need not other auxiliary facilities when implementing operation.Further, when being welded to the headwall blank flat on the headwall frame, to connect at edge on the parallel group of sheet separation direction and the side weld of headwall blank flat earlier, again edge on the direction of orthogonal sets sheet separation and the side weld of headwall blank flat are connect, make that when carrying out the welding of parallel group of sheet separation direction the welding that can crack, utilization group sheet separation produces is shunk and eliminated welding deformation, thereby further reduce distortion, and residual stress relieving, further improve the intensity of end wall panel.
