Embodiment Construction

[0025] The content of the present invention will be described below in conjunction with specific embodiments.

[0026] Such as figure 1 Shown is a method for manufacturing a split forming head according to the present invention. The manufacturing method is to use melon petals and a large diameter top circular plate to be divided into strips. The assembly method is to assemble the ports upward. First, the top circular plate is divided After the pressing and grouping are completed, the melon petals are pressed and the qualified melon petals are directly assembled on the top round plate, and finally the whole experience is received;

[0027] The steps of the manufacturing method of the split forming head are as follows:

[0028] Step 1: Make the melon plate mold according to the user's drawings and technical requirements;

[0029] Step 2: Cut the melon flap plate, the top round plate is not cut, and the drum hoisting tool is welded, and the single material plate and the three-dimensiona...

Abstract

The invention discloses a segmental molding making method of an end socket. The method comprises the following steps: step 1, making a segmental plate mould; step 2, making single material plate and vertical material plates and checking; step 3, gluing kraft paper to the surfaces of material pieces for protection, polishing the working surface of the segmental plate mould and wiping clean; step 4, carrying out compression molding; step 5, after cutting, trimming; step 6, beveling, trimming after welding, scribing and cutting; step 7, assembling, clamping, brushing a paint, and assembling a top circle; step 8, leveling, determining height, and drawing an end opening cutting line; step 9, cutting the end surface of the top circle, cutting segment small openings according to the actual size of the end surface of the top circle, and then assembling segments; step 10, after finishing all assembly in the step 9, leveling the end surface, determining the height, and drawing an end opening cutting line; step 11, cutting an end opening, and examining the whole; and step 12, packaging and loading onto a vehicle. The number of the split segments is reduced, the utilizing rate of materials is increased, the length of weld joints is reduced, the manufacturing cycle is short, and actual use requirements are met.

Description

Technical field [0001] The invention relates to a manufacturing method of a split forming head, which belongs to the technical field of manufacturing and forming. Background technique [0002] The head is a kind of boiler part in the pressure vessel. It is usually used at the two ends of the pressure vessel. There is also a welded pipe fitting product used for plugging the end of the pipeline. There are many forms. The head is the end cap on the pressure vessel, and it is a main pressure-bearing part of the pressure vessel. It plays a role of sealing; one is the upper and lower bottoms of the tank-shaped pressure vessel, and the other is the end of the pipeline. Extend it forward, then use a head to seal the pipe in the form of welding; products that are similar to the head include blind plates and caps, but those two products can be removed, and the head After being welded, it cannot be disassembled. The matching pipe fittings include pressure vessels, pipes, flanges, elbows, t...
