Four-mode oil compressor head machine

Abstract

The invention discloses a four-mold oil pressure necking machine. The four-mold oil pressure necking machine comprises a rack, an engine base, a hydraulic system, four oil pressure necking mechanisms and a cooling system capable of cooling the oil pressure necking mechanisms, wherein the engine base is arranged at the top of the rack, the four oil pressure necking mechanisms are arranged on the engine base in a circle center symmetrical manner and form a mold port, the hydraulic system is connected with the four oil pressure necking mechanisms and can drive the four oil pressure necking mechanisms to stretch and retract oppositely and simultaneously to enable the mold port to be in a reducing or increasing state, the necking effect is good, uniform wall thickness of a drawing tube is guaranteed, and concentricity is high. The four-mold oil pressure necking machine is skillful and reasonable in design, simple and convenient to operate, little in working noise, high in machining efficiency, wide in application range, compact in overall structure, small in size, stable in work, high in safety and reliability, shortens the production cycle effectively, reduces the cost, can neck tubes with different sizes and specifications without frequent mold replacement, occupies small area and facilitates extensive promotion and application.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a four-mode oil compression head machine. Background technique [0002] Tube necking is a forming process that reduces the diameter of the end of the tube blank. The tube blank enters the deformation zone under the action of axial force, and produces tangential shrinkage plastic deformation in the deformation zone, then enters the stable zone, and finally forms a reduced end diameter. At present, most of the common head shrinking machines in China are driven by air hammer or ball structure, which not only has high working noise, but also has low processing efficiency, and also has great safety hazards, which brings inconvenience to the operation. Pipes also need to be shut down frequently to replace the inner module, which is time-consuming and laborious, resulting in a long production cycle and high processing costs. Contents of the invention [0003] In view of the ...
