Problems solved by technology

[0003] Square heads for mobile vehicle-mounted oil storage tanks are large and thin, and are prone to deformation during drum spinning
In addition, the corner R of the square head is too small, the pressing process produces a lot of stress, and the stress is released during the groove, and the head is easily deformed

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, a kind of high-strength square head processing technology described in the present invention, it comprises the following steps,

[0027] (1) Make the head forming mold;

[0028] (2) cutting;

[0029] (3) Hot stamping: one-time molding to make the main body of the square head;

[0030] (4) Groove and water-cooling elimination: fix the main body of the square head on the special tooling, then inject water into the main body of the square head as a whole, use the magnetic wheel cutting machine to bevel, and then use the edge tearing machine to bevel the angle;

[0031] (5) Groove grinding, surface pickling, partial grinding, overall surface treatment, and overall acceptance;

[0032] In step (3), the main body of the square head includes a four-sided arc-shaped botto...

Abstract

The invention relates to a high-strength square sealing head processing technology which comprises the following steps: 1, manufacturing a sealing head forming die; 2, discharging; 3, carrying out hotstamping; 4, grooving and eliminating stress through water cooling; and 5, carrying out groove polishing, surface acid pickling, local polishing, overall surface treatment and overall acceptance. According to the high-strength square sealing head processing technology, stamping forming is carried out, and during the grooving process, fixation is carried out and stress is eliminated through watercooling, so that deformation is effectively prevented, and the yield is high.

Description

technical field [0001] The invention relates to a head processing technology, in particular to a square head processing technology. Background technique [0002] At present, as a pressure component, the head has been widely used in various industries such as medical treatment, transportation, and textiles. The head is an indispensable part of the container equipment. According to the purpose of the container and the operating pressure, the oval head, the dish head, the hemispherical head, the spherical head, the cone with or without the edge can be used. Shaped head, flat-bottomed head, etc. [0003] The square head used for the mobile vehicle-mounted oil storage tank is large and thin, and it is easy to deform during the drum spinning process. In addition, if the corner R of the square head is too small, a large stress will be generated during the pressing process, and the stress will be released during the groove, and the head will be easily deformed. Contents of the i...
