Abstract
The utility model discloses a novel welded elbow, which comprises an elbow body (1) and two welds (2) arranged thereon. The novel welded elbow is characterized in that the two welds (2) are symmetrically arranged on neutral surfaces of the elbow body (1). The two welds are symmetrically arranged on the neutral surfaces of the elbow body, and therefore, the welded elbow is composed of an outer cambered forming part and an inner cambered forming part respectively formed by pressing two dies prior to being welded together. Flat-developing drawings of the two forming parts are arc complementary, leftover is avoided for the two forming parts after inner arc and outer arc are developed, and material utilization rate is higher. Additionally, the inner arc side of the elbow is the weakest part, and thinning rate of thickness of the outer arc during formation is higher. The welds of the novel welded elbow are isolated from the inner arc and the outer arc and arranged on the neutral surfaces of the elbow, and accordingly strength of the welded elbow is enhanced.
Description
Affiliated technical field
The utility model belongs to bend pipe tools, a kind of specifically weld ell.
Background technique
At present, in the pipeline equipment manufacture, the weld seam of weld ell in the outer arc side together, the inner arc side together, two-part of weld ell are symmetrical, under plate be the same, all be fan-shaped, with a mold compression moulding.This weld ell unfolding and cutting, the clout residue is more, and irregular, but does not have value, and stock utilization is a kind of waste of resource 80%.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved weld ell is provided, and its stock utilization height has been saved raw material, has also strengthened elbow intensity.
For reaching above-mentioned purpose, the utility model is taked following technological scheme: the utility model includes: elbow main body and top weld seam thereof is characterized in that: the twice weld seam is symmetrical to be located on the neutral surface of elbow main body.
The utility model is taked technique scheme, have following beneficial effect: the twice weld seam of the utility model weld ell is symmetrical to be located on the neutral surface of elbow main body, like this, two profiled members forming weld ell are outer arced surface profiled member and intrados profiled member, two respectively by the compression moulding respectively of two molds, then to welding together.The plane outspread drawing of two profiled members just in time is the circular arc complementation, after inside and outside arc launches, does not have clout between them.Have only the lath two ends that clout is arranged, lath is long more, and stock utilization is high more, and stock utilization can reach about 95%.Though many sleeve forming moulds, the utilization ratio of material improves about 15%.The most outstanding characteristics are: the weakest part of elbow is the inner arc side, and outer arc wall thickness reduction when moulding is bigger, and this kind improvement makes weld seam break away from inner arc and outer arc, transfers on the neutral surface of elbow, has improved the intensity of weld ell.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the utility model embodiment's a main TV structure sketch.
Fig. 2 is the utility model embodiment's a side-looking structure diagram.
Fig. 3 is the utility model embodiment's a unfolded drawing.
Mark among the figure: 1-elbow main body, 2-weld seam, 3-inner arc sheet, 4-outer arc sheet.
Embodiment
By Fig. 1, shown in Figure 2, the utility model includes: elbow main body and top weld seam thereof, the twice weld seam is symmetrical to be located on the neutral surface of elbow main body.
By shown in Figure 3, the utility model after the weld seam expansion, is formed inner arc sheet 3, outer arc sheet 4, as can be seen, inner arc sheet 3, outer arc sheet 4 remedy mutually, do not have clout, like this, have just improved the utilization ratio of material.
Claims (1)
1. novel weld ell, it includes: elbow main body (1) and top weld seam (2) thereof is characterized in that: twice weld seam (2) is symmetrical to be located on the neutral surface of elbow main body (1).
