Detailed Description

Referring to fig. 1-3, the guiding loop for metallurgy, disclosed by the utility model, is characterized in that the guiding roller 2 is arranged at the front end and the rear end (namely the feeding end and the discharging end) of the guiding frame 1 and is used for supporting and guiding an entering bar or wire, in order to improve the guiding adjustment capability of the loop, the bottom of the guiding frame 1 is provided with the travelling wheel 1.1 and then slides on the track 101, and the moving direction of the guiding frame 1 is vertical to the advancing direction of the bar or wire along the guiding roller 2, so that the bar or wire is convenient to switch between different production lines, and is coordinated to overhaul and maintain. Simultaneously, install shutdown mechanism 4 and lifting buffer mechanism 5 respectively at the discharge end and the feed end of leading truck 1, shutdown mechanism 4 is used for cutting off the operation to rod or wire rod, and lifting buffer mechanism 5 is used for carrying out the lifting to preceding rod or wire rod when cutting off to the rod or wire rod that does not go forward bumps into down and cuts off the shutdown mechanism 4 that the operation had not yet reached and lift up the reset, thereby guaranteed the continuity of production line, avoided causing the damage to rod or wire rod product and even caused the incident.

Referring to fig. 2, the cutting mechanism 4 is composed of a cutter arm 4.1, a driving cylinder 4.2 and a blade 4.3, the middle part of the cutter arm 4.1 is hinged on the guide frame 1 through a pin shaft, the lower end of the cutter arm 4.1 is provided with the blade 4.3, the upper end of the cutter arm 4.1 is hinged with a piston rod of the driving cylinder 4.2, and a cylinder seat of the driving cylinder 4.2 is hinged on the guide frame 1. When the cutter arm is in operation, the driving cylinder 4.2 drives the cutter arm 4.1 to rotate, and in the clockwise downward rotation process, the cutter edge 4.3 at the head of the cutter arm 4.1 cuts off a bar or a wire in operation; thereby the fixed length cutting of the bar or the wire rod can be realized through the cutting mechanism 4, and the organic integration of the cutting function is realized.

Referring to fig. 3, the lifting buffer mechanism 5 includes a lifting arm 5.1, a lifting cylinder 5.2 and a lifting roller 5.3, the middle part of the lifting arm 5.1 is hinged on the guide frame 1, the upper part of the lifting arm 5.1 is provided with the lifting roller 5.3, the lifting roller 5.3 is horizontally placed between and horizontally connected with the two guide rollers 2 at ordinary times, and the lifting buffer mechanism can also be used for lifting bars or wires between the two guide rollers 2, the lower part of the lifting arm 5.1 is hinged with a piston rod of the lifting cylinder 5.2, and a cylinder seat of the lifting cylinder 5.2 is hinged on the guide frame 1. During operation, the lifting cylinder 5.2 drives the lifting arm 5.1 to rotate, when the lifting arm 5.1 rotates upwards clockwise to lift up a bar or a wire in operation, the lifting roller 5.3 arranged at the end part of the lifting arm 5.1 lifts up the bar or the wire in operation, and after taking the contact point of the bar or the wire with the guide roller 2 at the feeding end as a fulcrum, the bar or the wire at one end after being cut off in the advancing process rotates anticlockwise under the supporting action of the lifting roller 5.3, so that the end part after the bar or the wire is cut off rotates anticlockwise to separate from the cutting mechanism 4 which is not yet reset, and the collision and the influence on production are avoided.

Referring to fig. 1, at the same time, the pressing rollers 3 are arranged above the two guide rollers 2, and by adjusting the height of the pressing rollers 3, when the bar is not required to be cut off and only needs to be guided conventionally, the bar can be adjusted downwards to play a limiting role, when the bar is cut off and is upward adjusted, the pressing rollers 3 at the feeding end are used for limiting the lifting buffer mechanism 5 to prevent the rotation transition of the lifting buffer mechanism, and the pressing rollers 3 at the discharging end are used for limiting the lifted bar or the current, so that the bar is prevented from being bent to affect the quality due to the fact that the lifting excessive gravity center is deviated. Further, the press roller 3 is installed on a lifting frame, the lifting frame is installed on the guide frame 1 through a lifting adjusting mechanism, and the lifting adjusting mechanism can adopt a screw-nut structure or an air cylinder, an oil cylinder, an electric push rod and the like.
