Abstract
The invention discloses a carbon steel head hot pressing technology. The technology comprises the steps that sundries on a blank are removed thoroughly before charging, the diameter, the thickness and the materials of the blank are checked with a pattern, and the temperature rise recording preparation is made; the blank charging temperature is larger than 600 DEG C, then heating along with a furnace is carried out, the heating temperature is smaller than or equal to 1050 DEG C, and the final pressure temperature is larger than or equal to 850 DEG C; hot punching forming is adopted, a die is coated with lubricating agent formed by mixing 40% of graphite powder and 60% of engine oil before punching is carried out, a demolded head is cooled to be at the temperature being 600 DEG C, and then the head is taken out from the bottom of a lower die. The carbon steel head hot pressing technology is simple and convenient to implement, equipment is simple, the cost is low, the production efficiency is high, and the surface quality of the pressed head is good.
Description
Technical field
The invention belongs to end socket heat pressing process, be specifically related to a kind of carbon steel end socket heat pressing process.
Background technology
End socket, as parts indispensable in normal pressure and pressure resistant vessel, is widely used in the fields such as pharmacy, food, chemical industry, biology, water treatment, environmental protection, electric power, boilers and pressure vessel.Current carbon steel end socket heat pressing process complicated operation, wayward.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, a kind of carbon steel end socket heat pressing process is provided, simple to operate.
Carbon steel end socket heat pressing process provided by the invention, technological process comprises:
Preparation before the heating of a, end cover blank: before shove charge, the foreign material on blank are clean clearly, checks blank diameter, thickness and material and pattern, and carries out the record preparation that heats up;
B, charging heating: blank charging temperature is greater than 600 DEG C, then with stove heating, heating-up temperature≤1050 DEG C, final pressure temperature >=850 DEG C;
C, compacting: adopt heat stamping and shaping, be coated with the lubricant mixed by 40% graphite powder and 60% machine oil, from the low taking-up of counterdie after the end socket after the demoulding is cooled to 600 DEG C before punching press on mould.
Carbon steel end socket heat pressing process provided by the invention, its beneficial effect is, simple to operation, and equipment is simple, and cost is low, and production efficiency is high, and the end socket surface quality of compacting is good.
Detailed description of the invention
Below in conjunction with an embodiment, carbon steel end socket heat pressing process provided by the invention is described in detail.
Embodiment
