Machine tool for ring mold gun drill

Abstract

The invention relates to a machine tool for a ring mold gun drill. The machine tool for the ring mold gun drill comprises a machine tool body (1), two sets of feeding sliding tables (2), a numerical control rotary table (3), a gun drill drilling power mechanism (4), a high-pressure cutting oil system and an electric control system, the two sets of feeding sliding tables (2) are transversely fixed on the two sides of the upper portion of the machine tool body (1) respectively, the numerical control rotary table (3) is arranged above the middle position of the machine tool body (1), and the gun drill drilling power mechanism (4) is arranged on the feeding sliding tables (2); the gun drill drilling power mechanism (4) comprises a drilling head support base (12), a drilling main shaft (13), a tool rod (14) and a main shaft motor (18); the electric control system is respectively connected with a servo motor (7), a transmission motor (11) and the main shaft motor (18). The machine tool for the ring mold gun drill has the advantages of being capable of achieving efficient drilling machining of the ring mold, low in surface roughness of a machined mold hole, reducing labor intensity and low in oil spray escaping, according with environmental-protection hygienic requirements, being low in overall machine energy cost, and saving electric power.

Description

technical field [0001] The invention relates to a machine tool, in particular to a special machine tool for ring die gun drilling. Background technique [0002] The ring die is suitable for the processing technology of feed and biological granulation. The ring die is one of its key components. In the process of producing materials, the ring die is a vulnerable part, and the extrusion of materials in the die holes consumes a lot of electric energy. The ring die itself is integrated, in the shape of a hollow cylinder with a certain wall thickness. There are several radial through holes on the outer periphery of the ring die. The through holes are die holes. The number of die holes usually has 5000-40000 holes. Also only Ф1mm ~ Ф5mm. The traditional ring die hole processing adopts twist drill processing, which is inefficient and takes a long time and the surface of the processed hole is rough, which consumes more power when producing feed. The number of die holes and the sma...

Problems solved by technology

The traditional ring die hole processing is processed by twist drill, which is inefficient and takes a long time and the surface of the processed hole is rough, which consumes more power when producing feed

The number of die holes and the small diameter lead to high processing difficulty and long processing time, and corresponding high standards are put forward for the trouble-free and stable operation of the machine tool; due to the limitation of domestic technical level, if the gun drilling technology is used to process the ring die, the tool needs to be imported from abroad. Imported, the tool cost is very high, so there are strict requirements on the machine tool spindle and feed system

At present, most of the ring dies are processed by twist drilling, which is time-consuming, laborious and has low processing accuracy.
