Description

Splicing seam fixing structure for metal box

Technical Field

The utility model relates to the technical field of case manufacturing, in particular to a splicing seam fixing structure for a metal case.

Background

In the current luggage manufacturing industry, the forming mode of the metal case is generally divided into an integral forming mode and a bending forming mode, wherein due to process limitation, a splicing seam 1 shown in figure 1 exists on the general case by adopting the bending forming mode. Before the metal case shell carries out surface treatment, in order to avoid the case shell rigidity not enough and the condition that appears warping or damaging, generally can adopt welding or riveted mode to fix in case shell splice joint department, but in actual production, these fixed modes can bring following problem for the processing technology of case and bag usually:

(1) in the processing mode of welding fixation, because the welding spot of welding process is in the state of relative driving fit around, this also can make the concatenation seam of case shell form a relatively airtight space, the metal case shell usually needs to wash earlier before carrying out surface treatment to need use the washing liquid in the cleaning process, these airtight spaces that produce because of the welding spot can lead to the unable complete row of washing liquid in the cleaning process, remaining washing liquid can produce harmful effects to surface treatment process, finally lead to the case shell because of surface treatment bad reworking or scrapping. In addition, the welding process can generate welding scars on the surface of the box shell, so that welding can be performed only at positions covered by other parts, the application limitation is large, and the applicable range is very small. Meanwhile, the welding process sometimes causes the phenomenon of welding spot desoldering due to the fact that the operation of the welding process is not standard, and the case shell is easy to deform or damage.

(2) In the processing mode of adopting riveting fixation, generally, the case shell that adopts solid rivet directly to fix the splice seam department, riveting process can control the elasticity of case shell splice seam through control riveted elasticity, can avoid the problem of washing liquid remaining and weld scar among the above-mentioned welding process to a certain extent, but because metal case shell still need assemble with other parts (such as angle bead, parts such as frame) after carrying out surface treatment, and the solid rivet that uses can obstruct the equipment of other parts during riveting, so need spend extra manpower and materials to go on cleaing away of solid rivet before the case shell is assembled, carry out the equipment between case shell and other parts again, its work efficiency is low, case manufacturing cost and cost of labor are higher, be unfavorable for the mass production of case and bag.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provides a splicing seam fixing structure for a metal case, which has stable fixing effect and wide applicability, can adapt to the rapid assembly of the case shell and other parts of the case, effectively improves the production efficiency and reduces the production cost.

The technical scheme of the utility model is as follows: the utility model provides a concatenation seam fixed knot that metal case package was used constructs, includes the first edge of case shell, case shell second edge and hollow rivet, and the first edge of case shell and case shell second edge form superimposed state from top to bottom in the concatenation seam department of case shell, fix through hollow rivet between the first edge of case shell and the case shell second edge, and the boss of hollow rivet upper and lower both sides hugs closely respectively in the surface at the first edge of case shell and the surface at case shell second edge.
