Abstract

The utility model relates to a steel tilting machine which relates to a rolled part conveying device during section rolling and belongs the technical field of a steel rolling device. The utility model aims to solve the technical problem of providing a steel tilting machine which is capable of stopping a shape steel rolled part being conveyed to idling procedure and directly coveys the shape steel rolled part to a corresponding conveying roller way. The utility model comprises a motor, a long shaft and rotary arms arranged on the long shaft, wherein, one end of each rotary arm is fixedly connected with the long shaft, and the other end a steel tilting fork composed of a horizontal fork leg and an oblique fork leg; the long shaft is supported between conveying roller ways in a rolling production line through a bearing seat and forms transmission connection with a motor; when the steel tilting fork rotates along with the rotary arms, the rolled parts on the conveying roller ways before the idling procedure is carried out can be lifted and can be transmitted to a corresponding conveying roller way. The problem that different rolling technological processes can not be carried out on the same section rolling production line is solved, and the use disadvantages, such as idling procedure, rolling time extension, abrasion, energy consumption increase, etc., are eliminated; the utility model has the advantage of simple and compact structure and is suitable for being assembled and used in various section rolling production lines.

Description

Tilting gear

Technical field

The utility model relates to rolled piece conveying device in the rolling of sectional iron, especially rolled piece is transformed into mechanical device on another rollgang by a certain rollgang, belongs to the steel rolling equipment technical field.

Background technology

Milling train in the rolling of sectional iron production line, rollgang etc. are that the manufacturing technique requirent configuration that takes into account multiple section bar is arranged, so that the production line that builds up can adapt to the rolling use of multiple section bar.In other words, promptly utilize the multiple shaped steel of production line Rolling Production as far as possible.As the medium-sized section bar workshop in a certain φ 650MM roller footpath, the rolling line of its foundation can satisfy the Rolling Production of 14#～22# channel-section steel, 12.5#～16# angle steel, 11#～12# I-steel, 60#～multiple shaped steel such as 115# square steel.Because different shaped steel, its production technology can not be identical, and the wider rolling line of this accommodation can run into the unwanted situation of some operation and equipment when being used for the Rolling Production of a certain concrete shaped steel.In the rolling line of above-mentioned φ 650MM roller footpath, milling train is arranged by four of two row, the following square steel of channel-section steel, angle steel, I-steel and 115# needs to carry toward cold bed the rolling back of totally 8～14 passages through four milling trains in row, two row, and the 115# square steel only needs can transport to cold bed behind 6 passages of first and second rolling mill in row rolling, the the 3rd, the 4th rolling mill and the rollgang of back are redundant equipment, rollgang by third and fourth rolling mill and front and back is unnecessary operation, and this situation is the common problem that often faces in the section rolling production.When running into this kind situation at present, can only handle according to dry run.Still be example with above-mentioned, promptly the 115# square steel still need continue to be transported to the 3rd, the 4th rolling mill through rollgang, could be transported to cold bed after covering whole technological processes.The operation of rolling that this has prolonged some section bar undoubtedly, it is consuming time to have increased production, also can increase the wearing and tearing of equipment and the consumption of electric energy because of dry run simultaneously.If can utilize the conveying of certain device interrupt-type steel rolling piece relevant devices in the dry run operation, and it directly is transferred on the corresponding rollgang, will eliminate the use defective of above-mentioned rolling of sectional iron production line undoubtedly.

Summary of the invention

But technical problem to be solved in the utility model provides the conveying of a kind of interrupt-type steel rolling piece to the dry run operation, and it directly is transferred to tilting gear on the corresponding rollgang, to overcome the use defective of existing rolling of sectional iron production line.

The alleged problem of the utility model realizes with following technical solution:

A kind of tilting gear, it comprises motor 1, major axis 2, turning arm 3, described turning arm quantity is some, be intervally arranged on major axis, one end of turning arm is fixedlyed connected with major axis, the other end has and turns over steel fork 3-1, turn over steel fork and be made of the level fork leg and the fork leg that tilts, described major axis is supported between the rollgang in the rolling line and with motor by bearing block and is in transmission connection.

For the steel fork resting position is turned in convenient control, above-mentioned tilting gear, fixedlying connected of described turning arm and major axis set up fan-shaped counterweight 5 on the end, and an end of described major axis has additional register control 4.

Above-mentioned tilting gear, the inclination angle A of described inclination fork leg is 30 °～50 °.

The interval on major axis that the utility model provides is provided with turning arm, utilize on the turning arm turn over steel fork when rotating with turning arm with the dry run operation before rolled piece on the rollgang hold up, and be transferred to design on the corresponding rollgang, solved the problem that on same rolling of sectional iron production line, can't implement different rolling mill practice flow processs, thereby make each concrete section bar be rolled production according to required technological process, eliminated the dry run operation, also eliminated simultaneously the rolling time prolongation that the dry run operation is brought, wearing and tearing, power consumption increases to wait uses defective, has improved the technical matters level of rolling of sectional iron; In addition, it is little that the utility model also has a volume simple and compact for structure, can be placed in the characteristics between the rollgang of respectively arranging of rolling line easily, suits to install and use in various section rolling production lines.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is an A-A cutaway view among Fig. 1;

The specific embodiment

Consult Fig. 1,2, in the illustrated embodiment, 7 is rollgang before the empty operation, 8 rollgangs that should go for rolled piece, major axis 2 is supported between

rollgang

7 and 8 by a plurality of bearing block 11 rotations, major axis is formed by two short axle butt joints, motor 1 is by decelerator 6, shaft coupling 9 and two are in transmission connection than minor axis, the quantity of turning arm 3 is 6, be distributed on the major axis 2, rotate synchronously with major axis, the length of turning arm is looked rollgang 7, row's spacing between 8 and deciding, spacing between the turning arm is corresponding consistent with the spacing of rollgang middle roll, and the inclination angle A that turns over steel fork 3-1 medium dip fork leg is 40 °, and controller 4 adopts the cam structure controller, model is LK4-044, during the every Rotate 180 of major axis °, with major axis synchronously the cam of rotation and the locating piece in the controller collide, motor 1 is shut down, and major axis is parked on this position.
