Abstract

A flange-welded steel drum is provided, wherein the flange edge of the drum body and the drum bottom are welded integrally along the whole circumference. The flange-welded steel drum comprises a drum body (1), a drum bottom (2) and flanged edges (3) and is characterized in that the flange edges (3) of the drum body (1) and the drum bottom (2) are welded integrally along the whole circumference, forming a circumferential weld (4) at the welding positions (5, 6 or 7). The weld may be single-ring or multi-ring weld and performed by any one of the resistance welding, gas welding and laser welding methods. The utility model can integrate the drum body and the drum bottom or cover as a whole by welding, thereby greatly increasing the flange toughness, so that the flange is prevented from leakage even being shocked and deformed during the collision process of the steel drum. Therefore, the service life of the metal drum is significantly improved.

Description

Crimping welding steel drum

One, technical field

The utility model belongs to a kind of can that is used for object or storing material or transportation, especially for the metal drum of carrying liquid.

Two, background technology

Existing metal drum all constitutes for being connected by the roll of steel plate limit, wherein ladle body itself has a crimping, ladle body respectively has a crimping again with the bucket end and bung, in order to guarantee the leak tightness of crimping, crimping mostly is the 5-7 layer, when though this crimping bucket has just dispatched from the factory, through check is the seepage phenomenon can not occur, but the carrying of using, in the handling process, owing to reasons such as collisions, crimping promptly can produce deformation, and, be not real one material, so in crimping generation deformation because ladle body and bucket are respectively by two block plate cigarettes together the ends, just easily cause seepage, therefore necessary the improvement.

Three, summary of the invention

The utility model is the deficiency at existing metal drum, and the crimping place that the proposes a kind of metal drum in addition mode of welding all around makes the ladle body of metal drum and the material at the bucket end material that fuses into one.Its position of weld can be arbitrary position of crimping, and its welding manner can be flash butt welding, gas welding or laser beam welding.

The utility model makes the material of ladle body and the bucket end or bung molten for one by welding, strengthened the toughness of crimping so greatly, made steel drum in collision process, crimping is hit distortion, can can not carry the service life of metal drum greatly because of seepage appears in distortion yet.

Four, description of drawings

Fig. 1 launches scheme drawing for the utility model crimping;

Fig. 2 is the utility model crimping shaping back scheme drawing;

Among the figure, 1. 3. crimpings 4,5,6 at the bottom of 2. barrels of the ladle bodies, 7. weld nugget.

Five, the specific embodiment

From accompanying drawing as can be seen, the utility model is in the welding of ladle body with the whole circle of crimping place enforcement at the bucket end, it comprises ladle body 1, the bucket end 2 and crimping 3, it is characterized in that on the crimping 3 of ladle body 1 and the bucket ends 2 cigarette, having the weld nugget 4 of whole circle, and the position of weld also can be 5,6 or 7, can be the individual pen welding, also can be the multi-turn welding, and welding manner can be any mode of flash butt welding, gas welding, laser beam welding.

Claims

1, crimping welding steel drum comprises ladle body (1), the bucket end (2) and crimping (3), it is characterized in that having on the crimping (3) of ladle body (1) and the bucket end (2) cigarette the weld nugget (4) of whole circle.

2, crimping welding steel drum as claimed in claim 1 is characterized in that weld nugget (4) can be the individual pen welding, also can be the multi-turn welding.

3, crimping welding steel drum as claimed in claim 1 is characterized in that weld nugget (4) can be any position of (4), (5), (6) or (7).

4, crimping welding steel drum as claimed in claim 1, the welding manner that it is characterized in that weld nugget (4) can be any mode of flash butt welding, gas welding, laser beam welding.
