Description

Dry pressing forming equipment Technical Field The utility model relates to the field of dry-pressing forming processing, in particular to dry-pressing forming equipment. Background Dry press forming refers to a green body forming method which is more commonly used in ceramic production. Adding a small amount of adhesive into the powder for granulating, then loading into a die, pressurizing on a press machine to enable the powder particles to approach each other in the die, and firmly combining by virtue of internal friction force to form a blank body with a certain shape. The dry pressing forming equipment in the market generally uses a die to carry out die assembly and pressure maintaining, so that materials are firmly combined by means of internal friction force, a preliminary shaped product can be obtained after die opening, and the products are subsequently required to be placed into a heating furnace for heating, so that full shaping is realized. However, the hardness of the preliminarily shaped product is low, so that the product is easy to collide and damage in the carrying process, the production quality of the product is reduced, and meanwhile, the production efficiency is low. Therefore, a heating and heat-preserving device is necessarily arranged in the dry pressing die, so that the products can be heated and solidified after being clamped and shaped, and secondary furnace returning operation is avoided, and the production quality of the products is ensured.
