Vertical feeding steel winding prevention device in cold rolling production

Abstract

A vertical feeding steel winding prevention device in cold rolling production comprises a charging barrel, a shaft in the vertical direction is fixedly connected to the end center of the charging barrel, the inner end of a rotating arm is rotationally connected to the shaft, a round hole is formed in the position close to the outer end of the rotating arm, a steel bar penetrates through the round hole, and the round hole and the charging barrel do not coincide on the projection in the overlook direction. During feeding operation, reinforcing steel bars penetrate through the round holes in the edge of the rotating arm, the reinforcing steel bars drive the rotating arm to rotate flexibly in the uncoiling and straightening process, in this way, the reinforcing steel bars are damped and straightened, all the reinforcing steel bars in the front-back nested state are straightened after passing through the round holes, and therefore subsequent steel winding accidents are avoided, and the service life of the reinforcing steel bars is prolonged. After the device is used on the high-speed cold-rolled wire feeding telescopic charging barrel, steel winding accidents are basically eradicated.

Description

Technical Field

[0001] The utility model relates to a feeding device in cold-rolled steel bar production, in particular to a vertical feeding anti-steel-winding device in cold-rolled production, belonging to the technical field of cold-rolling equipment. Background Technique

[0002] In cold-rolled ribbed steel bar production equipment, the function of the feeding machine is to pull out the coiled hot-rolled wire rod raw material from the head, straighten and descale it, and then send it to the subsequent rolling area. In production practice, vertical feeding machines are commonly seen. For the vertical feeding machine, refer to patent ZL201410092198.0. When feeding, the steel bar is located on the material cylinder (the material cylinder is also called the core cylinder, and the cross arm b in patent ZL201410092198.0 is the material cylinder). The vertical feeding machine can make full use of the free gravity of the steel bar during the pulling process of the steel bar, which can eliminate part of the steel-winding accidents caused by the mutual nesting of steel bars. Its failure rate is relatively low, and it can adapt to a relatively high production speed. In order to prevent the occurrence of steel-winding accidents at a higher speed, a telescopic material cylinder is adopted in the vertical feeding machine (refer to patent ZL201410764150.X), which is located at the center of the coil and plays a guiding role during the uncoiling process, preventing the steel-winding accidents caused by the rollover of the steel bar during the straightening and rising process, and further reducing the equipment accident rate to a certain extent. After taking the above measures, the equipment accident rate is greatly reduced. However, due to the complexity of the hot-rolled raw material coil shape, the steel-winding accidents of the steel bar still cannot be completely avoided, and still occur 2-5 times per shift (8 hours) on average. Summary of the Invention

[0003] The purpose of the utility model is to overcome the occurrence of steel-winding accidents in the current vertical feeding, and provide a vertical feeding anti-steel-winding device in cold-rolled production.

[0004] To achieve the purpose of the utility model, the following technical solutions are adopted: A vertical feeding anti-steel-winding device in cold-rolled production includes a material cylinder. A vertical shaft is fixedly connected to the center of the end of the material cylinder. The inner end of the rotating arm is rotatably connected to the shaft. A round hole is opened near the outer end of the rotating arm. The steel bar passes through the round hole. In the projection in the top view direction, the round hole does not coincide with the material cylinder.

[0005] Further; the material cylinder is a telescopic material cylinder for high-speed cold-rolled wire feeding.

[0006] Further; the rotating arm is rotatably connected to the shaft through a bearing.

[0007] The positive and beneficial technical effects of the present utility model are as follows: During the feeding operation, the steel bars pass through the round holes at the edge of the rotating arm. When the steel bars are uncoiled and straightened, they drive the rotating arm to rotate flexibly at the same time. In this way, it plays a damping and straightening role for the steel bars. All the steel bars in the front-back nested state are straightened after passing through the round holes, thus avoiding subsequent steel bar winding accidents. After using this device on the telescopic barrel for feeding high-speed cold-rolled wire rods, the occurrence of steel bar winding accidents is basically eliminated.
