Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] as attached figure 1 with attached figure 2 The shown riveted seam steel pipe is a steel plate bent into a closed cylinder 1 as a whole, and the edges on both sides of the seam 2 forming the closed cylinder 1 are respectively provided with a notch array composed of a plurality of notches 3, And the shape of the protruding part 4 between the adjacent notches 3 is the same as that of the notches 3; the notch arrays at the two side edges of the seam 2 are arranged in a staggered manner and are embedded and riveted together.

[0015] Preferably, the shape of the notch 3 is Ω-shaped, and the Ω-shaped notch 3 has a better overlap, is not easy to disengage, and has a larger occlusal area.

[0016] In order to ensure airtightness, such as figure 2 As shown, the two side edges of the seam 2 forming the closed cylinder 1 have overlapping parts after being riveted tog...

Abstract

The invention discloses a riveting type joint seam steel pipe, which is integrally a steel plate bent into a closed tube body; notch arrays formed by a plurality of notches are respectively formed in the edges of the two sides of a joint seam forming the closed tube body; the shape of a projected part between the adjacent notches is identical to the shape of the notches; the notch arrays at the edge parts of the two sides of the joint seam position are in staggered arrangement and are mutually embedded and riveted. The riveting type joint seam steel pipe has the advantages that the forming work procedures are few; the cost is low; the embedding riveting is performed through the notch arrays in staggered arrangement in a curled steel plate butt joint edge position; the intensity is high; a lamination part is arranged in the joint seam position; the air tightness is good; the riveting type joint seam steel pipe is applicable to occasions such as automobiles with high requirements on the steel pipe intensity and air tightness.

Description

technical field [0001] The invention relates to a steel pipe, especially a seamed steel pipe. Background technique [0002] Steel pipes are widely used in automobiles and other fields. For example, various types of steel pipes are involved in automobile bumpers, engines, and exhaust pipes. The above-mentioned steel pipes are all thin-walled steel pipes. There are currently two types of steel pipes on the market. Seamless steel pipes, one is welded steel pipes, seamless steel pipes are integrally drawn and formed by drawing machines and other equipment, which have high strength and good sealing performance, but the cost is the highest, and special drawing equipment is required, and the purchase and maintenance costs of equipment Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding. The production process of welded steel pipe is simple, the production efficiency is high, there are many varieties and specif...
