Quick push dropping mechanism and discharge mechanism of screw heading machine

Abstract

The invention discloses a quick push dropping mechanism and a discharge mechanism of a screw heading machine. The dropping mechanism comprises a first guide rail, a first guide rail seat, an arc body,a driving wheel, a reset spring, a second guide rail, a second guide rail seat and a push rod. The first guide rail is mounted and operate in the first guide rail seat. The second guide rail is mounted and operate in the second guide rail seat. The arc body is fixed to the first guide rail and moves left and right along with the first guide rail. The front end of the second guide rail is connected with the push rod. The push rod moves front and back along with the second guide rail. The rear end of the second guide rail is hinged o the driving wheel. The upper surface of the arc body is a cambered surface. The cambered surface of the arc body makes contact with the outer circumferential surface of the driving wheel. The second guide rail is connected with the reset spring. The quick pushdropping mechanism and a discharge mechanism can enable blanks to fall quickly. The defect that scrap materials are generated during slow dropping is overcome. The equipment production speed is increased. Manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of screw heading machines, in particular to a fast pushing and blanking mechanism and a material returning mechanism of a screw heading machine. Background technique [0002] The screw heading machine belongs to the cold heading equipment, the function is basically a single die or one die with two punches, mainly used for forming the heads of products such as screws and rivets, and its working principle is: wire straightening, wire feeding, cutting, feeding into the die , initial forging, forming, blank exit. It works in one go, and can produce about 180 pieces per minute. [0003] Existing technology and its disadvantages: the current material return mechanism of the screw head machine only needs to adjust the material return speed, and the adjustment method is by adjusting the position of the material return cam. In the process of processing, after the billet is formed and withdrawn, due to the high spee...

Problems solved by technology

[0003] Existing technology and its deficiencies: the current material return mechanism of the screw head machine only has the speed adjustment of the material return, and the adjustment method is by adjusting the position of the material return cam

[0007] After searching, in the ejector mechanism of the head-heading machine in the prior art, the ejector pins of the conventional ejection mechanism are all ejected, and no rapid auxiliary push-and-fall mechanism similar to the present application has been found, and no rapid-assist push-and-fall mechanism has been found. The comprehensive mechanism that the material mechanism is applied to the conventional return mechanism
