Background

The process flow of C-shaped steel processing is as follows: the strip steel coil is uncoiled through a feeding machine, then fed into a C-shaped steel forming machine, the strip steel is bent and formed through the C-shaped steel forming machine, and then cooled and cut off after forming, and finally preparation is completed. The uncoiler is one of essential important devices in a welded pipe production line, and is used for supporting a steel coil through an inner hole of the tensioned steel coil and feeding the head of the steel coil into a forming machine through the matching of a rotating roller at the tail part of a C-shaped steel forming machine. The influence of the good or bad performance of the unwinder on the whole production line is thus of great importance. In design practice for many years, the structure of the uncoiler is continuously optimized and improved, so that the performance of the uncoiler is improved.

After the steel coil is tensioned by the tensioning mechanism of the uncoiler, the steel coil rotates under the traction of the C-shaped steel forming machine, so that the tensioning mechanism is driven to rotate. The C-shaped steel forming machine is continuously dragged, but the C-shaped steel forming machine is intermittently dragged due to the influence of various factors in the production process. When the traction is stopped or the traction speed is reduced, the tensioning mechanism can continue to rotate due to inertia, so that the strip steel is bounced outwards, and the strip steel coil and the tensioning mechanism skid.

Utilize the arc hole 640 of seting up on the limiting plate 630 to restrict second gag lever post 650 to restricting the rotation space of gyro wheel 620, avoiding gyro wheel 620 turned angle too big, making the removal of base 100 too nimble, be unfavorable for the worker to control loading attachment's moving direction.

The implementation principle of the movable strip steel feeding device in the embodiment of the application is as follows: the steel coil is sleeved outside the tensioning mechanism 400, and the push-pull rod 421 is rotated to move the push-pull rod 421 toward the supporting roller 200, so as to drive the sleeve 410 to move toward the direction close to the turntable 320. The drum moves towards the direction close to the rotating disc 320, the second connecting plate 432 is subjected to a force in the direction away from the rotating roller 310 along the radial direction of the rotating disc 320, the second connecting plate 432 slides on the rotating disc 320 along the radial direction of the rotating disc 320, and in the sliding process of the second connecting plate 432, the abutting plate 434 is firstly abutted with the inner contact of the steel ring. The sleeve 410 is pulled further, the spring between the support plate 433 and the abutment plate 434 is compressed by the support plate 433, and when the compression of the spring is completed, the movement of the sleeve 410 is stopped. When the steel plate is bounced outwards, the abutting plate 434 moves in the radial direction of the rotating roller 310 away from the rotating roller 310 under the action of the elastic force of the spring, so that the inner ring of the steel coil is kept tensioned, and the steel coil is prevented from slipping. The tension mechanism 400 tensions the inner ring of the steel coil to support the strip steel coil, and the steel coil rotates under the traction of the C-shaped steel forming machine, so as to drive the tension mechanism 400 to rotate. The tensioning mechanism 400 and the rotating mechanism 300 rotate synchronously, the rotating mechanism 300 is connected in the supporting roller 200 in a rotating mode, and the supporting roller 200 is supported by the base 100, so that the steel coil rotates on the feeding device stably.

After the steel coil is installed on the tensioning mechanism 400, the fastening bolt 530 is rotated to move toward the direction close to the rotating roller 310, and the fastening bolt 530 moves to drive the limiting wheel 560 to move. After spacing wheel 560 and coil of strip outer lane butt, continue to rotate fastening bolt 530, compression spring, at the in-process that the coil of strip radius constantly reduces, spacing wheel 560 keeps the butt with the steel ring at the elastic force effect of spring, prevents that the steel ring from playing outward.

The rolling mechanism 600 is fixedly connected to the base 100, and the sliding friction between the base 100 and the ground is replaced by the rolling friction between the rolling mechanism 600 and the ground, so that the friction force between the feeding device and the ground is reduced, and the feeding device can move on the ground.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
