Description

Segmentation guider

Technical Field

The utility model relates to the technical field of steel rolling equipment, in particular to a splitting guide device.

Background

When the deformed steel bar is produced, the finished product front rolling mill is a flat rolling mill, the finished product rack is a vertical rolling mill for realizing non-torsion rolling, and during rolling, the red steel enters the finished product rack from the finished product front rack and is guided by a guide device to realize the non-torsion rolling. The stand pipe among the guider sets up to two square pipes of arranging side by side at present, and during the screw-thread steel segmentation rolling, need to introduce the finished product frame to square pipe back through the difference, has certain contained angle with square pipe when red steel gets into square pipe like this for red steel is at the outside surface sliding friction of square pipe inside facing, and the side wearing and tearing are more, especially apart from square pipe export 30cm department, rubs easily and leads to red steel to fly out and produce production accidents such as rolling mill steel suffocates.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is as follows: the technical problem that a traditional guide pipe is easy to wear through is solved.

The utility model provides a cutting guide device, wherein a guide pipe of the cutting guide device is provided with two parallel square pipes, guide wheels are arranged on the side surfaces of the square pipes which are arranged in a back-to-back mode, and the guide wheels are located at the position 30cm away from the outlet of the square pipes.

When the red steel passes through the outlet 30cm of the square tube, the red steel is in rolling connection with the guide wheel, so that the friction force of the red steel is reduced, and the red steel stably enters a finished product rolling mill; the utility model reduces the abrasion of the side wall of the square tube, avoids steel flying accidents caused by the abrasion of the guide tube, improves the production efficiency and ensures the safe production.

To explain the installation structure of the guide wheel, in the scheme, the guide wheel is installed on a support, and the support is clamped with the upper end surface and the lower end surface of the square tube.

In order to ensure that the guide wheel is installed more stably, the bracket comprises two side plates arranged in parallel and a web plate connected with the side plates, the side plates and the web plate form a U-shaped groove, and the guide wheel is installed at the end part of the U-shaped groove; the side plates are clamped with the upper end surface and the lower end surface of the square tube. So set up, increased the area of contact of curb plate with square pipe to make the support mounting more firm, the guide pulley installation is more firm.

The guide wheel is easy to increase in temperature after long-term contact with the red steel, so that damage is caused, the problem is further improved and solved, and particularly, the support is further provided with a cooling water pipe for cooling the guide wheel.

In order to prolong the service life of the guide wheel, in the scheme, the bracket is also provided with an oil-gas pipe for supplying oil to the bearing; the bearing is used for realizing the rolling of the guide wheel. The bearing adopts the bearing that has the lubricated interface of oil gas, and the oil gas pipe is connected with the lubricated interface of oil gas, lubricates the bearing to improve the life of bearing, and indirectly improve the life of guide pulley.

In order to explain the position relationship between the guide wheel and the inner wall of the square tube, in the scheme, the guide wheel protrudes out of the inner wall of the square tube.

In order to prevent the guide wheel from influencing the smooth penetration of the red steel out of the square tube, in the scheme, the guide wheel protrudes 1-3mm from the inner wall of the square tube.

In order to explain the material of the guide wheel, in the scheme, the material of the guide wheel is Cr12 MoV. So set up, guide pulley intensity is higher, and life is longer.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

The first embodiment is as follows:

as shown in fig. 1-3, the present invention is a cutting guide device, wherein the guide tube is two parallel square tubes 1, the side surfaces of the square tubes 1 opposite to each other are provided with guide wheels 2, and the guide wheels 2 are located at 30cm of the outlet of the square tube 1 and protrude out of the inner wall of the square tube 1.

Guide pulley 2 installs on support 3, and support 3 joint side pipe 1 upper and lower both ends face to it is fixed to realize guide pulley 2 installation.

When the red steel passes through the outlet 30cm of the square tube 1, the red steel is in rolling connection with the guide wheel 2, so that the friction force of the red steel is reduced, and the red steel stably enters a finished product rolling mill; the utility model reduces the abrasion of the side wall of the square tube 1, avoids steel flying accidents caused by the abrasion of the guide tube, improves the production efficiency and ensures the safe production.

Example two:

compared with the first embodiment, the differences are as follows: the bracket 3 comprises two side plates 31 arranged in parallel and a web plate 32 connected with the side plates 31, the side plates 31 and the web plate 32 form a U-shaped groove, and the guide wheel 2 is arranged at the end part of the U-shaped groove; the side plates 31 are clamped on the upper and lower end surfaces of the square tube 1. So set up, increased curb plate 31 and the area of contact of square 1 pipe to it is more firm to make the installation of support 3, and the installation of guide pulley 2 is more firm.
