Conjugate cam reciprocating pull clip seat rocker mechanism

Abstract

A conjugate cam reciprocating pulling tong seat rocker arm mechanism comprises a rocker arm bearing, an arched rocker arm, a secondary cam rocker arm, a long transmission shaft and a conjugate cam set arranged on the long transmission shaft, wherein the middle portion of the arched rocker arm and the upper end portion of the secondary cam rocker arm are both hinged to the rocker arm bearing through a bearing hinging shaft, the conjugate cam set is located below the rocker arm bearing and is arranged between the arched rocker arm and the secondary cam rocker arm, the arched rocker arm and the secondary cam rocker arm are provided with a first roller and a second roller respectively, the first roller and the second roller correspond to a conjugate primary cam and a conjugate secondary cam of the conjugate cam set respectively and are connected with the conjugate primary cam and the conjugate secondary cam respectively in a contacted mode, a first hinging small shaft and a second hinging small shaft are arranged in an installation hole in the lower end portion of the arched rocker arm and an installation in the lower end portion of the secondary cam rocker arm respectively, and the first hinging small shaft is connected with the second hinging small shaft through an elastic link mechanism. The conjugate cam reciprocating pulling tong seat rocker arm mechanism has the advantages of being low alternating load, low in noise, and high in moving speed.

Description

technical field [0001] The invention relates to the technical field of cold heading machines, in particular to a conjugate cam reciprocating pulling clip seat rocker mechanism of a cold heading machine. Background technique [0002] Cold heading machine is a machine for upsetting and forging metal at normal temperature. It can be used for mass production of fasteners such as nuts and bolts. The cold heading machine of the prior art usually includes a mold box, a head clip block slide block and a crank link mechanism arranged between the drive mechanism and the head clip block slide block. However, since the crank-link mechanism of the cold heading machine in the prior art has the disadvantages of high alternating load, high noise and low moving speed, it needs to be further improved. [0003] The cold heading machine of the prior art urgently needs a transmission mechanism with a more reasonable structure for transmitting power to the heading slider, and after structural im...

Problems solved by technology

However, due to the disadvantages of high alternating load, high noise and low speed of motion in the crank-link mechanism of the cold heading machine in the prior art, it needs to be further improved.

[0003] The cold heading machine of the prior art urgently needs a transmission mechanism with a more reasonable structure for transmitting power to the heading slider, and after structural improvement, the transmission mechanism must be able to overcome the alternating load of the transmission mechanism of the prior art Disadvantages of high, loud noise, and low movement speed
