Hydraulic auxiliary support structure for recoiling machine

Abstract

The invention relates to a hydraulic auxiliary support structure for a recoiling machine, which comprises a rotary shaft, an upright post, a support arm, an oil cylinder base, a first pin shaft, an oil cylinder, a second pin shaft, a taper sleeve, a bearing and a bearing cap. The bearing is arranged in an inner hole of the support arm; the taper sleeve is arranged in an inner hole of the bearing; the bearing is tightly pressed by the bearing cap and screwed by using a bolt; the support arm is in fitting joint with the upright post through the rotary shaft; the lower part of the support arm is connected with the oil cylinder through the second pin shaft; and the oil cylinder is connected with the oil cylinder base through the first pin shaft. The hydraulic auxiliary support structure of the invention has the advantages of stable recoiling in a belt material recoiling process, improvement on product quality, security guarantee, convenient operation, simple structure and convenient manufacturing.

Description

technical field [0001] The invention relates to a hydraulic auxiliary support structure of a coiler, which belongs to an auxiliary device in a strip cold rolling equipment, and is matched with the coiler for hydraulic auxiliary support of the coiler. Background technique [0002] At present, in widely used strip cold rolling mills, since the diameter of the rolled strip coiled in the coiler increases, the coil weight becomes heavier and heavier, which increases the load carried by the main shaft of the coiler. As the auxiliary equipment of the coiler, the hydraulic auxiliary support of the coiler plays a very important role. The coiler used in the past does not have hydraulic auxiliary support, which makes the main shaft of the coiler fatigue bending or even break after being used for a period of time due to the increase of bearing capacity. The winding spindle is bent and deformed. When the coiler is coiling the strip, the strip shakes, the tension required for the strip i...

AI Technical Summary

Problems solved by technology

However, the coiler used in the past did not have hydraulic auxiliary support, which caused the main shaft of the coiler to bend due to fatigue and even break after being used for a period of time due to the increase in bearing capacity.

The winding spindle is bent and deformed. When the coiler is coiling the strip, the strip shakes, the tension required for the strip is unstable, and the two sides of the strip appear tight and loose at the same time, and the edges of the coiled strip are not neat. , When rolling thinner strips, broken strips often occur, which affects the quality and output of strips; if the coiling spindle breaks, it will cause equipment accidents, and even endanger the lives of operators.
