Background

The finishing of the section after rolling has two processes, one is the traditional hot sawing cut-to-length and cut-to-length straightening process, and the other is the newer long-length cooling, long-length straightening and cold sawing process.

The straightening is the more prominent part of the profile finishing. The straightening difficulty of the sectional material is higher than that of a plate and a pipe, and the reasons are as follows: firstly, in the cooling process, the bending is large due to the asymmetric section and the uneven temperature; secondly, the section coefficient of the section is large, and the required straightening force is large. Because the section of a rolled piece is large, the roll spacing of the straightening machine is also large, the straightening blind area is large, and the use of steel is greatly influenced under some conditions, such as: the straightening blind area of the heavy rail obviously reduces the full-length flatness of the heavy rail. The straightening blind area is reduced, a variable intercept straightener is used as a measure on equipment, and long-ruler straightening is used as a measure on the process.

Therefore, the deformation control of the section bar is particularly noticed during cutting, particularly when the hollow section bar and the side edge of the section bar are provided with the thin reinforcing rib structure section bar, when the section bar is cut, the cutting sheet which runs at a high speed drives the weak structure of the section bar to vibrate, and then the section bar is subjected to impact deformation during cutting.

Before cutting, the first electric push rod 105 pulls the switching slide rod 106 to move inwards along the lower fixing plate 101, so that the switching slide rod 106 drives the left push rod 107 and the right push rod 109 to perform cross turning, the left push rod 107 and the right push rod 109 simultaneously drive the upper fixing plate 111, the support plate 112 and the reed 113 to move downwards, so that the two main support assemblies are in a folded state, then the two main support assemblies are respectively plugged into two sides of the hollow section, an operator holds an infrared emitter to respectively irradiate the infrared receivers 103 in the two main support assemblies on the outer sides of the section, the drive wheel 102 drives the lower fixing plate 101 and the connected parts to move to the depth of the hollow section, so that the two main support assemblies respectively move to two sides of the saw blade of the electric saw 401, and then the first electric push rod 105 drives the switching slide rod 106 to push outwards along the lower fixing plate 101, so that the upper fixing plate 111 drives the support plate 112 and the reed 113 to lift upwards, when the support plate 112 comes into contact with the inner top of the profile, the support plate 112 is turned downwards against the shape of the inner top of the profile, while the compressed spring 113 provides an inner supporting force against the inside of the profile via the support plate 112.

Then, the electric sliding block 202 drives the shell 203 to move towards the rear side of the section bar along the sliding rail 201, so that the spring sliding block 204 on the front side of the shell 203 drives the clamping plate 205 to cling to the weak reinforcing ribs on the side surface of the section bar, and sand is filled in the cavity of the shell 203.

Then the second electric push rod 402 is controlled to push out outwards, the sawtooth sheets of the electric saw 401 start to run, the sawtooth sheets cut the position of the section between the two groups of main supporting components, the two groups of main supporting components respectively provide internal supporting force for two sides of the cut position of the section, the clamping plate 205 structurally supports and fills up the reinforcing ribs with weak side faces of the section, meanwhile, sand filled in the shell 203 absorbs kinetic energy generated by vibration, so that the vibration phenomenon generated on the section during cutting is weakened, when the sawtooth sheets cut the section into two halves, the two groups of clamping plates 408 moving downwards respectively press the section cut into two parts downwards, and the shaking caused by the transfer of the supporting center at the moment when the section is cut off is avoided.
