Length detection and automatic feeding and discharging device for short metal bar stocks

Abstract

The invention discloses a length detection and automatic feeding and discharging device for short metal bar stocks, and belongs to the technical field of mechanical bar stock conveying devices. A transition plate (8) is arranged between a primary chain (14) and a secondary chain (19). A length sensor (7) is arranged above the secondary chain (19). A screening cylinder (26) is fixedly arranged on a bracket (27) on one side of the secondary chain (19), and is perpendicular to the secondary chain (19). A screening cylinder pushing plate (6) is fixedly arranged at the extending end of the screening cylinder (26). A transverse cylinder (25) is arranged on one side of the rear part of the secondary chain (19), and is perpendicular to the secondary chain (19). A transverse cylinder pushing plate (3) is fixedly arranged at the extending end of the transverse cylinder. According to the device, the transition plate, the length sensor, the screening cylinder, the screening cylinder pushing plate, the transverse cylinder, the transverse cylinder pushing plate, a longitudinal cylinder and a longitudinal cylinder pushing plate are additionally arranged, so that the heating continuity and stability of the short metal bar stocks are improved, the forging and pressing accuracy is improved, and high automation degree is ensured.

Description

technical field [0001] The invention relates to a length detection and automatic feeding and discharging device, in particular to a short metal rod length detection and automatic feeding and discharging device, which belongs to the technical field of mechanical conveying rods. Background technique [0002] At present, in the forging production line, through the transmission of the chain, the short metal bars arranged on the chain will enter the heating furnace for heating, and the length detection and automatic distribution of the short metal bars cannot be carried out during the transportation process. The influence of the shearing machine in the first process, during the cutting process, the length of the short metal bar will vary, and the length is not the same. The front part of another bar that follows it will also be mixed in with the transmission direction of the chain, and the length of the short metal bar will be unqualified, which not only increases the product rej...

Problems solved by technology

[0002] At present, in the forging production line, through the transmission of the chain, the short metal bars arranged on the chain will enter the heating furnace for heating, and the length detection and automatic distribution of the short metal bars cannot be carried out during the transportation process. The influence of the shearing machine in the first process, during the cutting process, the length of the short metal bar will vary, and the length is not the same. The front part of another bar that follows it will also be mixed in with the transmission direction of the chain, and the length of the short metal bar will be unqualified, which not only increases the product rejection rate, but sometimes causes the automatic feeding and discharging device jamming, forcing the production line to stop, resulting in wasted energy and reduced output

In the past, in the conveying process of metal short bars, wastes with unqualified lengths were manually removed based on experience, and the delivered short bars were manually pushed into the material rail, so that there was a certain gap between the front and rear short bars. This approach not only requires high personnel, but also the heating time of the metal short bar is not fixed, resulting in inconsistent heating temperature, affecting the forging precision and quality, resulting in waste of manpower and resources
