Embodiment 1

[0029] Such as figure 1 and 2As shown, the integrated shearing and feeding mechanism of a cold heading machine provided in this embodiment includes a scissor plate 1, and an installation groove 2 is opened on the top of the scissor plate 1, and a pair of installation grooves 2 The auxiliary clip shaft 3 is hinged with a scissors auxiliary lever 4 between the side walls of the groove. An auxiliary clip elastic element longitudinal support 5 is also fixed, and an auxiliary clip elastic element transverse support 6 is jointly supported on the above-mentioned two auxiliary clip elastic element longitudinal supports 5, and an auxiliary clip runs through the auxiliary clip elastic element transverse support 6. The elastic element shaft 7, the auxiliary clip elastic element shaft 7 passes through the auxiliary clip elastic element transverse support 6, and is axially limited by screwing a hexagon nut assembly 8, and the above-mentioned auxiliary clip elastic element shaft 7 is sleev...

Embodiment 2

[0032] The integrated shearing and feeding mechanism of a cold heading machine provided in this embodiment has a general structure consistent with that of Embodiment 1, such as Figure 5 As shown, but in the present embodiment, an end portion of the paw release lever 14 is additionally provided with a paw release lever press bar 23, which is in a mutual transmission structure with the relative high end 18 of the above-mentioned scissors auxiliary lever 4.

Embodiment 3

[0034] The integrated shearing and feeding mechanism of a cold heading machine provided in this embodiment has a general structure consistent with that of Embodiment 2, such as Figure 6 and Figure 7 As shown, but in this embodiment, the scissors board 1 is also fixed with a wire stopper 24, and the wire stopper 24 is provided with a stopper notch 25 overlapping with the scissors mouth 12 of the scissors board 1 above.

[0035] The addition of the above-mentioned wire stopper 24 can increase the axial contact area between the scissors mouth 12 and the wire, thereby improving the clamping stability of the auxiliary scissors clip 11 during the entire cutting and feeding process.

Abstract

The invention discloses an actuator of a cold heading machine, and particularly relates to an integrated material cutting and feeding mechanism of the cold heading machine. The integrated material cutting and feeding mechanism of the cold heading machine adopts the technical scheme that two mechanical actions of material cutting and material feeding of the cold heading machine are combined to be completed, so that the aims of shortening work cycles of material cutting and material feeding of the cold heading machine, and improving the transmission precision of the cold heading machine are achieved, and the processing efficiency and the processing precision of the cold heading machine are improved favorably.

Description

technical field [0001] The invention relates to an actuator of a cold heading machine, in particular to an integrated shearing and feeding mechanism of a cold heading machine. Background technique [0002] Cold heading machine is a special mechanical equipment mainly used for mass production of fasteners such as nuts and bolts. [0003] The overall structure of the existing cold heading machine can be divided into main transmission mechanism, feeding mechanism, shearing machine [0004] There are five major parts including structure, cold heading forming mechanism and ejection and blanking mechanism. During the wire rod processing process of the cold heading machine, the metal wire rod is sent to the shearing mechanism under the action of the above-mentioned feeding mechanism. The metal blank is sent to the cold heading forming mechanism for plastic forming. In the above whole process, the cutting and feeding of the metal wire are two relatively independent mechanical act...
