Main die rotary type high-speed cold heading machine

Abstract

The invention relates to a main die rotary type high-speed cold heading machine. A cold heading device further comprises a main die rotary mechanism, wherein the main die rotary mechanism comprises a rotary type main die seat; the main die seat is assembled on a machine body and can rotate; the main die seat is sequentially provided with a plurality of heading working stations corresponding stamping dies one by one, and a material returning working station corresponding to the position of a material returning device; the material returning working station and the heading working stations are uniformly distributed on the same circumference; each working station of the main die seat is correspondingly provided with a main die; the main die seat is connected with an interval indexing device for driving the main die seat to rotate at interval to realize the switching of the working stations of the main die; each stamping die is positioned and mounted on a stamping die slide seat and corresponds to the position of the corresponding cold heading working station. The switching of the working stations is realized by main die rotation; the main die rotary type high-speed cold heading machine has the advantages of compact structure, good production stability, high machining precision and high working efficiency.

Description

technical field [0001] The invention relates to the technical field of cold heading machines. Background technique [0002] The cold heading machine is a special equipment mainly used for mass production of fasteners such as nuts and bolts. According to the theory of metal plastic deformation, a certain pressure is applied to the metal blank at room temperature to cause plastic deformation in the mold cavity, and it is formed according to the specified shape and size. [0003] The main structure of the cold heading machine is: including a fuselage, a power device, a wire feeding device, a cutting and feeding device, a piercing device, and a material return device are installed on the fuselage. The power device includes a drive motor, and the output of the drive motor The end is connected to the crankshaft after passing through the gearbox, and the crankshaft is connected to the countershaft, and other devices are connected to the crankshaft or the countershaft through the c...

Problems solved by technology

In this way, when the punch is matched with the main mold, two actions need to be performed—the upsetting action and the switching action between stations, which have defects such as poor equipment accuracy, poor working stability, short mold life, and low work efficiency.
