The bracket 501 is fixed on the upper right end of the workbench 6, the outer material bin 502 is installed on the bracket 501, the upper end of the outer material bin 502 is provided with a feeding port 502a, and the inner material bin 503 is located at the feeding port 502a directly below, the inner material bin 503 is fixedly connected with the outer material bin 502, the upper end of the dial plate 504 is hinged with the upper part of the inner material bin 503, and the material dial cylinder 505 is fixed on the right side of the inner material bin 503 On the wall, the material shifting cylinder 505 is hinged with the lower right part of the shifting plate 504, the lower opening of the inner material bin 503 is set, and the reclaiming wheel 506 is located at the lower opening of the inner material bin 503. The take-up wheel 506 is connected to the inner side wall of the outer material bin 502 through a bearing, and the material guide channel 507 is installed on the lower left side of the opening of the inner material bin 503, and the lower end outlet of the material guide channel 507 is close to the conveying chain plate 403, the runner 509 is fixed on the bottom of the outer bin 502, the runner 509 is crushed on the outer surface of the conveyor chain plate 403, the lower end of the connecting rod 508 is eccentrically hinged with the runner 509, and the connecting rod The upper end of 508 is eccentrically hinged with the pick-up wheel 506 . The reclaiming wheel 506 is provided with a semicircular retrieving groove 506a. The eccentricity of the hinge between the rotating wheel 509 and the connecting rod 508 is smaller than the eccentricity of the hinge between the reclaiming wheel 506 and the connecting rod 508 . What the single material conveyor 5 adopts is the principle of the crank rocker mechanism, and utilizes the characteristic of the reciprocating swing of the rocker to realize the output of bar stock, that is, the crank rocker mechanism is formed by using the reclaiming wheel 506, the connecting rod 508, and the runner 509, wherein, The eccentricity of the hinge of the runner 509 and the connecting rod 508 is the crank radius, and the eccentricity of the hinge of the reclaiming wheel 506 and the connecting rod 508 is the radius of the rocker, so that the crank radius is smaller than the rocker radius, and the crank can complete a circle Rotation, the application is as follows: during the rotation of the conveyor chain plate 403, since the runner 509 is crushed on the outer surface of the conveyor chain plate 403, the runner 509 can be rotated synchronously, and then the connecting rod 508 is driven to drive the take-off The reciprocating rotation of the material wheel 506 makes the feeding chute 506a move back and forth at the lowermost end of the inner feed bin 503 and the feed inlet of the guide channel 507. The groove 506a will be stuck into a bar, and then when the feeding groove 506a swings to the material inlet of the material guide channel 507, the bar is put into the material guide channel 507, and the bar material is transported to the corresponding material guide channel 507.

[0043] When working, the operator puts the bar into the inner bin 503 from the feeding port 502a, then starts the drive wheel 402, drives the conveyor chain plate 403 to rotate, and simultaneously makes the runner 509 roll to drive the reclaiming wheel 506 to reciprocate In this way, the retrieving trough 506a will move back and forth at the lowermost end of the inner material bin 503 and the material inlet of the material guide channel 507, and continuously transport the bar in the inner material bin 503 to the material guide channel 507 , that is, single-piece output, the output bar will fall onto the corresponding conveying pallet 404, and then use the rotation of the conveying chain plate 403 to transport the bar to the leftmost end of the conveying chain plate 403, and then use the take-out The material rack 308 catches the bar that is about to fall to complete the transfer of the bar. After that, the index motor 302 is started to drive the reclaiming turntable 310 to rotate, so that the bar on the reclaimer 308 is snapped into the No. 1 shaft bracket In 310b, the indexing motor 302 continues to rotate until the first bar moves to the uppermost position of the reclaiming turntable 310, the indexing motor 302 brakes, starts the stamping cylinder 2a, and drives the pressing head 2d to press on the bar correspondingly On the surface, the head of the bolt can be formed, and at the same time, the diameter reduction of the bolt can be realized to improve the efficiency of the bolt processing. After forming, the stamping cylinder 2a is reset, and the operator takes out the semi-finished product, and then loads it into the thread rolling machine to process the thread. Such cyclic operation can realize batch processing of bolts.
