Problems solved by technology

[0002] The cutting control of rails in a large-scale factory adopts a fixed baffle sizing system. The disadvantage is that the sizing specification is fixed and it is inconvenient to adjust. The sizing accuracy is within ±6mm
Every time the length is changed, the baffle needs to be moved and adjusted. Changing the length is difficult and takes a long time

Embodiment 1

[0034] 1) Taking the sawing machine 4 as the starting point, according to the fixed-length setting value on the rear track of the sawing machine 4, 26 meters (the fixed-length setting value is 25 meters), 51 meters (the fixed-length setting value is 50 meters) and 51 meters away from the sawing machine 4 sets of liftable laser range finders 1 are installed at 76 meters (the fixed-length setting value is 75 meters) and 101 meters (the fixed-length setting value is 100 meters).

[0035] 2) Install two sets of pinch rollers 3 on both sides of the rail on the rear side of the sawing machine 4 and the front side of the laser range finder;

[0036] The main function of adopting two sets of pinch roller 3 devices is to facilitate the centering of the rail 5 when the two pairs of hydraulic cylinders 3-2 are clamped, and to facilitate the laser detection of the end face of the rail 5. Because the power of the hydraulic motor 3-4 of one set of pinch rollers 3 can meet the requirements o...

Abstract

The invention provides a method and device for realizing the arbitrary fixed-length of a steel rail. The device comprises laser range finders and pinch rollers. The laser range finders are mounted ina sectioned mode on a track on the rear side of a sawing machine according to the fixed-length setting value, and the pinch rollers are mounted on the rear side of the sawing machine and the two sidesof the steel rail. Compared with the prior art, the method and device have the beneficial effects that the steel rail is subjected to whole process fixed-length monitoring through a non-contact laserfixed-length system on line, the system conducts anti-interference recognition processing on laser data information, operation information is formed and converted into an electrical signal of the prescribed form, and the steel rail is subjected to length control through an executing mechanism. The method and device have the advantages that the non-contact mode is achieved, the fixed-length precision is high, and fixed-length changing is convenient and fast.

Description

technical field [0001] The invention relates to the field of rail rolling, in particular to a method and a device for realizing arbitrary sizing of rails. Background technique [0002] A large-scale rail cutting control adopts a fixed baffle sizing system. The disadvantage is that the sizing specification is fixed and it is inconvenient to adjust, and the sizing accuracy is within ±6mm. It is necessary to move the baffle plate every time to change the fixed length and make adjustments. It is difficult to change the fixed length and takes a long time. In order to meet the needs of domestic and foreign customers for different rail sizes, it is necessary to design a set of arbitrary sizing system, which can be adjusted arbitrarily from 10m to 100m, and the accuracy is within ±4mm. Contents of the invention [0003] The object of the present invention is to provide a method and device for realizing arbitrary length of rails, which can meet the needs of customers for arbitrary...
