Problems solved by technology

[0002] At present, presses for manufacturing conventional heads generally refer to single-acting or double-acting hydraulic presses, air presses, hydraulic presses or mechanical presses; they mainly press elliptical heads and disc-shaped heads below 5 meters and below two layers. , conical head, large and small mouth, eccentric cone, spherical head, etc.; however, with the advancement of science and technology, industrial structure adjustment, the emergence of new materials and the improvement and strengthening of safety regulations With the continuous application of methods, special-shaped head products have emerged, such as: natural gas, ethers, benzene and other high-risk liquids, flammable and explosive liquids, and toxic and harmful liquids. Transport or storage tank head products; not only require the head Pressure-bearing, but also to play a buffer role in releasing the pressure in the tank, the reason is that the expansion coefficient of gas or liquid is large, and the physical or chemical stability is poor. The conventional manufacturing head technology is far from meeting the modern requirements of high safety and high reliability. The special-shaped head manufacturing technology with the function of absorbing gas or liquid expansion; therefore, thin-walled, special materials, and super-large straw hat-type three-layer special-shaped head products emerged as the times require, and conventional press equipment cannot meet the straw hat three-layer special-shaped head products. The manufacturing requirements of multi-layer special-shaped head products; therefore, the following defects and deficiencies exist in the use of conventional equipment to manufacture special-shaped heads
[0003] 1. The head product does not have the buffer function
[0004] 2. It is impossible to realize the one-time compression molding technology of special-shaped heads
[0005] 3. Manually repair the bulging and wrinkling points, using manual methods such as fire baking and sledgehammer smashing, and around the repair point, material degradation and increased thinning of the hitting point will occur, which will affect the quality of the head product

Abstract

The invention discloses irregular end seal manufacturing and a manufacturing method thereof. The irregular end seal manufacturing comprises a multi-moving press, a multi-moving module, an end seal plate blank, an irregular end seal blank, and irregular end seal shaping module and a gasket, wherein the irregular end seal shaping component comprises the gasket, a swelling wrinkle point, an upper side and a lower side; the gasket comprises an upper pad plate and a lower pad plate; the upper pad plate is adhered to an upper mold through sodium soap grease; the adhesion position is above the swelling wrinkle point; the lower pad plate is adhered to a lower mold through the sodium soap grease; the adhesion position is below the swelling wrinkle point; the upper mold further comprises a pressing mold, a pull ring module and a main mold; a jacking cylinder piston rod is connected with the irregular end seal blank. Due to adoption of a method that an irregular end seal is pressed in the sequence that the multi-moving pres and the multi-moving module for are combined, the end seal can be manufactured into a product that the capacity of the end seal is increased because of a three-layer shape deformation.

Description

technical field [0001] The invention relates to a head manufacturing technology, in particular to a special-shaped head manufacturing equipment and a manufacturing method.
