The invention belongs to the technical field of mechanical manufacturing methods, and particularly relates to an optimized manufacturing method of a welding elbow.
Background
In the welding manufacture of steel structural parts, a welding elbow structure is often used, and the welding elbow is generally large in number and always is segmented, blanked and curved. Therefore, the welding elbow has the problems of low utilization rate of blanking materials, incomplete consistency of each section of curved radius after the section is curved, great time for correcting the curvature radius during final welding, and unsatisfactory final welding appearance. An optimized fabrication method is therefore needed to solve the above problems.

The invention aims to provide an optimized manufacturing method of a welding elbow, which solves the problems of low blanking utilization rate and inconsistent curvature radius of the welding elbow caused by segmented blanking.
The technical scheme adopted by the invention is that the optimized manufacturing method of the welding elbow comprises the following steps:
step 1: cutting a plurality of sections of materials required for manufacturing the welding elbow into a whole square plate according to a blanking drawing, and intermittently cutting;
step 2: processing the square plate cut intermittently in the step 1 into a cylindrical shape by a curve machine;
and step 3: cutting the parts of the cylinders connected together after the curved machining in the step 2 until the parts are completely separated;
and 4, step 4: and (4) welding the cylinders cut in the step (3) to obtain the elbow.
The present invention is also characterized in that,
the specific manufacturing method of the blanking drawing in the step 1 is as follows: a, determining the number of elbow sections and the size of an elbow; and b, manufacturing an elbow joint line.
The method for cutting continuously in the step 1 comprises the following steps: the end is left uncut for 100mm, then cut for 1000mm, and left uncut for 100mm, and so on.
And the cutting mode in the step 1 and the step 3 adopts gas cutting.
The invention has the beneficial effects that:
the blanking and curved manufacturing method of the welding elbow is optimized, the manufacturing requirement of the welding elbow is met, the problems of low blanking utilization rate, complex curved shape and poor effect of the welding elbow are solved, the working efficiency is improved, the manufacturing of the welding elbow is facilitated, and the manufacturing cost is reduced.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Step 1: the method comprises the steps of blanking 4 sections of blank materials required by the original processing of the welded elbow into 1 piece of material according to a blanking diagram shown in figure 1, firstly determining the number of sections of the required elbow and the diameter of the elbow, determining a joint line between the elbows according to the diameter of the elbow, projecting the joint line of the elbows on a square plate, particularly noting a curve in the middle, and requiring intermittent cutting during blanking, namely, leaving 100mm for an end to be not cut, then performing gas cutting on the end with the length of 1000mm (the size can be adjusted), then leaving 100mm for not to be cut, and so on, particularly ensuring that the two sides of the material can not be subjected to gas cutting with the length of more than 100mm, thus the 4 pieces of material are blanked into a whole square plate.
Step 2: after blanking, the steel plate is integrally curled into a cylinder by a curling machine;
and step 3: gas cutting the parts of the connected cylinders formed after the curved shape in the step 2 to obtain 4 sections of cylinders provided with welding elbows;
and 4, step 4: the 4-section cylinder is welded according to the structure shown in figure 1 to obtain the elbow.
In the optimized manufacturing method of the welded elbow, the step 1 avoids waste in the process of gas cutting and blanking of the curved edge, and improves the utilization rate of a steel plate; the step 2 and the step 3 ensure that the curvature radiuses of the 4 sections of cylinders are consistent, the time of secondary verification when the 4 sections of cylinders are oppositely installed is reduced, and the installing and welding working efficiency of the welded elbow is improved.
