Problems solved by technology

However, due to the limitations of the existing head stamping process, the obtained heads often have certain problems. First, in the process of stamping and demoulding, some small holes are prone to appear on the surface of the head, which affects the appearance. Secondly, Due to insufficient surface treatment after stamping, the wear resistance and corrosion resistance of the head are poor, resulting in a relatively short service life

Embodiment 1

[0051] A stamping process of an ultra-thin head, comprising the following steps:

[0052] Step 1. Preheating treatment: place the head to be stamped at 200-300°C for heat treatment for 0.1-0.5 hours to obtain the preheated head body;

[0053] Step 2. Mold treatment: apply a release agent on both the inner surface of the die and the outer surface of the punch, and then place it at 90°C to 120°C for 0.1 to 0.5h to obtain the treated die and the treated die. punch;

[0054] Step 3, first stamping: placing the preheated head blank body inside the processed die, pressing down the processed punch for stamping, and obtaining a head blank connected to the die ;

[0055] Step 4, heat treatment: place the head blank body treated in step 3 together with the die under the condition of 180-200°C for heat treatment for 0.1-0.5h;

[0056] Step 5, Stamping again: pressing down the punch again to stamp the head body that has been heat-treated in Step 4;

[0057] Step 6, cooling treatment: ...

Embodiment 2

[0092] A stamping process of an ultra-thin head, comprising the following steps:

[0093] Step 1. Preheating treatment: place the head to be stamped at 200-300°C for heat treatment for 0.1-0.5 hours to obtain the preheated head body;

[0094] Step 2. Mold treatment: apply a release agent on both the inner surface of the die and the outer surface of the punch, and then place it at 90°C to 120°C for 0.1 to 0.5h to obtain the treated die and the treated die. punch;

[0095] Step 3, first stamping: placing the preheated head blank body inside the processed die, pressing down the processed punch for stamping, and obtaining a head blank connected to the die ;

[0096] Step 4, heat treatment: place the head blank body treated in step 3 together with the die under the condition of 180-200°C for heat treatment for 0.1-0.5h;

Abstract

The invention relates to the technical field of stamping, in particular to an ultrathin head stamping process. The ultrathin head stamping process comprises the following steps of 1, preheating treatment, 2, mold treatment, 3, stamping for the first time, 4, heating treatment, 5, stamping again, 6, cooling treatment, 7, washing passivation, 8, drying treatment, and 9, surface treatment. The ultrathin head stamping process solves the problem that in the stamping and stripping process, some small holes are prone to occur in the surface of a head, and secondly, due to the fact that surface treatment is not enough after stamping is finished, the head is poor in abrasion resistance and corrosion resistance, and short in service life; and the process can effectively improve the surface protection effect, avoids the situation that the internal texture stability is influence due to surface damage, can improve the quality of stamped products greatly, and ensures safety and stability of production and machining.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a stamping process of an ultra-thin head. Background technique [0002] The head is a kind of boiler part in the pressure vessel. It is usually used at both ends of the pressure vessel. Then there is a welded pipe fitting product used for sealing the end of the pipe. Ultra-thin heads are more difficult to prepare than ordinary heads, and require more precise process operations during the preparation process. However, due to the limitations of the existing head stamping process, the obtained heads often have certain problems. First, in the process of stamping and demoulding, some small holes are prone to appear on the surface of the head, which affects the appearance. Secondly, Due to insufficient surface treatment after stamping, the wear resistance and corrosion resistance of the head are poor, resulting in a relatively short service life.
