The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The present embodiment provides an automatic metal tube and bar feeding mechanism, as shown in fig. 1, comprising a spreading unit 20 and a collecting unit 30, wherein the spreading unit 20 is provided with a transmission mechanism 21, and the transmission mechanism 21 can drive a metal tube and bar 10 to roll when the metal tube and bar 10 is flatly held, and is in point contact with the outer wall surface of the metal tube and bar 10, so that the metal tube and bar 10 can be laid on the same plane in a single layer. The collecting unit 30 is disposed at the end position of the conveying mechanism 21 and is located lower than the conveying mechanism 21, and has a material frame seat 31 for receiving the metal tube bar 10, and the material frame seat 31 can gather the metal tube bar 10 together and stack the metal tube bar 10.

Specifically, the paving unit 20 comprises a plurality of groups of conveying mechanisms 21 arranged in parallel and a plurality of groups of racks 22 arranged at intervals with the conveying mechanisms 21; the racks 22 are of a steel frame structure, the racks 22 are arranged on two sides of each transmission mechanism 21, the moving transmission direction of each transmission mechanism 21 is perpendicular to the direction in which the metal tube and bar materials 10 are placed, and the transmission mechanisms 21 are arranged on the racks 22 and arranged along the length direction of the racks 21; during blanking, the metal tube rod 10 travels across the width of several sets of conveyors 21. A hydraulic device 23 for lifting the conveying mechanism 21 is further arranged below the rack 21, a discharging roller table 24 is arranged at one end of the rack 21, which is far away from the collecting unit 30, the metal tube and bar 10 is discharged from the furnace table after heat treatment is finished, and the metal tube and bar stops advancing at the position of the discharging roller table 24; hydraulic means 23 can control gantry 22 to raise the height of gantry 22 and indirectly the height of conveyor 21 so that metal bar 10 is free of outfeed roller table 24 and placed on conveyor 21.

As shown in fig. 2 and 3, each transmission mechanism 21 includes a chain 211 and a joist 212 supporting the chain 211, the joist 212 is fixed on the rack 22, and a circular shifting wheel 213 is provided in the middle of the link plate of the chain 211, the shifting wheel 213 is suspended between the chains 211 and is coaxially provided with the chain roller on the link plate of the chain 211, that is, when the chain 211 is driven by the motor and the sprocket to step, the chain 211 is supported by the joist 212, and no joist 212 is supported below the shifting wheel 213, and the chain is idle-running.

Further, the maximum outer diameter of the thumb wheel 213 is higher than the height of the chain 211, and is disposed along the length direction of the chain 211 in a staggered and crossed manner. The diameter height of the thumb wheel 213 is greater than the height of the chain 211, so that the metal tube bar 10 directly contacts with the thumb wheel 213 and is driven by the thumb wheel 213 to advance, the chain 211 only drives the thumb wheel 213 to move, and the metal tube bar 10 is prevented from contacting with the chain 211 so that the chain 211 cannot be driven by the gear. Moreover, the diameter of the thumb wheel 213 is relatively large, so that the thumb wheels 213 on the adjacent chains 211 are arranged in a staggered and partially overlapped manner, and further, an arc space is formed between the adjacent thumb wheels 213, because the thumb wheels 213 are of a circular structure and are in point contact with the surface of the metal tube bar 10, the metal tube bar 10 cannot be placed on the thumb wheels 213 independently and can only be clamped in the arc space between the adjacent thumb wheels 213, and thus the metal tube bar 10 cannot be overlapped and advanced, so that the metal tube bar 10 stacked on the thumb wheels 213 in a multilayer manner at the previous stage is gradually and flatly laid on the arc space of the adjacent thumb wheels 213 in a single layer manner along with the forward driving of the chains 211, and the spread metal tube bar 10 rolls in a self-rotating manner and gradually advances toward the side close to the aggregate unit 30 along with the forward movement of the chains 211.

Further, two sides of the chain 211 are provided with a flat beam 214, the flat beam 214 is of an L-shaped structure, and the flat beams are buckled on two sides of the chain 211. One side of the lay-flat beam 214 is disposed above the chain 211, and the other side is disposed on the outer side of the chain 211. The height of the flat beam 214 is less than that of the thumb wheel 213; and the distance between the adjacent flat beams 214 is greater than the width of the thumb wheel 213 and less than the width of the chain 211. This arrangement is mainly configured to protect the chain 211 from safely and smoothly traveling and working, while not affecting the driving of the metal bar 10 by the wheel 213.

As shown in fig. 4, the collecting unit 30 includes a plurality of material frame seats 31 arranged at intervals and material brackets 32 arranged between the material frame seats 31, in order to improve the stability of collecting the metal tube and bar 10, one material bracket 32 is arranged beside each material frame seat 31, and the outermost material frame seats 31 are arranged; all the material frame seats 31 and the material bracket seats 32 are fixed on the same fixed seat 33 side by side along the width direction of the transmission mechanism 21.

Such a slot 311 with a wide top and a narrow bottom facilitates the falling, gathering and stacking of the metal bars 10. The upper end surface of the clamping groove 311 is also the height that the upper end surface of the material frame seat 32 is slightly lower than the transmission mechanism 21, so that the metal tube bar 10 can fall down along the arc surface of the clamping groove 311. Meanwhile, in order to improve the strength of fixing the clamping groove 311 to the metal tube bar 10, the bottom position of the clamping groove 311 is set to be higher than the height of the fixed seat 33. The height of the card slot 311 near the transmission mechanism 21 is higher than the height of the card slot 311 far from the transmission mechanism 21, and the height of the card slot 311 near the transmission mechanism 21 is matched with the height of the transmission mechanism 21.
