Description

A kind of cold-rolled steel bar feeding equipment

technical field

The utility model relates to cold-rolled steel bar production equipment, in particular to a cold-rolled steel bar feeding equipment, which belongs to the technical field of cold-rolled steel bars.

Background technique

In the current technical field of cold-rolled steel bar production equipment, there are mainly two structural forms of the feeding machine in use: horizontal and vertical. The horizontal feeding machine has a simple structure, and generally adopts two "turret" type core barrels, and the material coils on the two core barrels are welded end to end to realize continuous feeding. Generally, it is equipped with a simple production line. , prone to entanglement, the feeding and uncoiling speeds generally cannot be higher than 200 m/min. The vertical feeder is mainly divided into double-stem vertical feeder and (single-stem) vertical feeder. The double-stem vertical feeder has two stems side by side, alternately feeding and uncoiling. The scale of this equipment is relatively small (a single set of equipment weighs about 6 tons), but it has the inherent defect that the operation state of the front and rear coil head-to-tail connection sections cannot be controlled when uncoiling, and the failure rate increases significantly when the uncoiling speed is higher than 300 m/min. . The single core column vertical feeding machine is mainly composed of three parts: feeding trolley, turning device and lifting device. The lifting device stacks the rolls that have been flipped into a vertical state vertically and concentrically, which overcomes the inherent defect of the existing double-column vertical feeder that unwinds alternately. Due to the action of gravity, the rolls are easy to separate when uncoiling The speed breakthrough has been increased to 1000 m/min. However, this kind of feeding equipment has a large scale, high manufacturing cost, and the equipment occupies a large space height. It is necessary to separate the workshop (a single set of equipment weighs about 20 tons and is more than 10 meters high), making it impossible for the production workshop to realize front and rear cranes. public interworking. In addition, the above-mentioned several feeding methods all realize the uncoiling by pulling the raw material horizontally or vertically naturally, which cannot avoid the operation failure of the steel winding when the shape of the raw material coil is greatly deformed.

The rear end of the mandrel 1 is tapered, as shown in 20, the large end of the tapered end is larger than the inner hole of the material roll, the tapered shape can prevent the material roll 21 from coming out, and the core tube 1 is penetrated in the inner hole of the material roll 21 In the hole, there is a notch 17 near the rear end of the hollow shaft, a fixed pulley 18 is installed on the notch, a roller frame 15 is fixedly installed near the front end of the hollow shaft, and two parallel rollers are installed on the roller frame 15 16. There is a closed space between the two rollers to ensure that the steel bars will not come out. The closed space can also be a closed space formed by four rollers. The four rollers are on the four sides of the rectangle, and the steel bars pass through the two rollers. After passing under the fixed pulley, it enters the hollow shaft and is drawn out from the rear end of the hollow shaft. In order to ensure that the hollow shaft can stop in time when the production line is stopped instantaneously, a brake 12 (brake device) is installed on the hollow shaft at the support, and the action of the brake can brake the hollow shaft. There are many brakes that can be applied at present, such as the holding brake brake, for example, the YWZ type holding brake of a certain enterprise can be used.
