Problems solved by technology

This method has the following problems: 1. The product is generally thicker than 40mm, and the product structure is composed of multi-section curved surfaces. It is welded into a rough shape with multiple steel plates, and the welding workload is large, and the welding deformation is difficult to control; 2. Due to the large deviation of the shape, The thickness of the feeding material needs to be more than doubled, and the material utilization efficiency is low, generally about 40%; 3. Due to the large processing allowance, the machining time is very long

Abstract

The invention relates to a novel hydroelectric conical tube end socket which comprises an end socket upper half portion and an end socket lower half portion which are fixedly connected through a connection plate. The end socket upper half portion is composed of twelve upper clacks, the end socket lower half portion is composed of twelve lower clacks, upper vertical rib plates are arranged among the upper clacks, and lower vertical rib plates are arranged among the lower clacks. The end socket is high in material utilization rate, less in welding and machining time and short in end socket manufacture period and greatly reduces production cost.

Description

Technical field [0001] The invention relates to a seal head, in particular to a split seal head. Background technique [0002] At present, the production of hydropower cones is made of steel plates with a lot of thickness (about 2 times the minimum thickness required), welded piece by piece at different angles, and then assembled as a whole and machined to the required shape and size. This method has the following problems: 1. The product generally has a plate thickness> 40mm, and the product structure is composed of multiple curved surfaces. Multiple steel plates are welded into a general shape. The welding workload is large and the welding deformation is difficult to control; 2. Due to the large shape deviation, The thickness of the feed material needs to be more than doubled, and the material utilization efficiency is low, generally about 40%; 3. Due to the large machining allowance, the machining time is very long. Summary of the invention [0003] Objective of the inventi...
