SU1701442A1 - Method for laying-out and cutting rolled products into cut lengths and device for its realization - Google Patents

Abstract

The invention relates to the processing of metals by pressure, in particular to metal-cutting equipment, and can be used to cut long-rolled products into measured lengths in the blank production. The purpose of the invention is to increase the yield when cutting, improving the quality of the products obtained and Type B 2 increasing productivity. The bar is fed to the cutting zone by the feed mechanism 4 relative to the sensors 23 installed along the feed mechanism. The front end of the car overlaps sensor 1, and a signal is sent from it to determine the last of the sensors covered by the car. The rear end of the bar released the last of the bar-covered sensors, and at the time of opening the sensor following it, a signal is received to stop the bar and produce a front waste segment that is less than or equal to half the cut length. The bar is moved as far as the stop 20, pushing the waste into the hole window 19. The bar is cut to lengths along the stop 20. The last workpiece is cut from the waste at the end of the bar, the value of which is less than or equal to half of the cut length. 1 hp f-ly, 5 ill. W fe

Claims (2)

Claim 1. The method of cutting and cutting to measured lengths of rolled metal, including the supply of a bar, the determination of the initial length of the cut bar, the determination of the magnitude of the length of the cut off from. bar stock, cutting and removal of end waste, characterized in that, in order to improve the quality of the products and productivity, before cutting the bar on the workpieces of measured length redistribute the magnitude of the non-multiplicity to the front and rear ends of the workpieces, and the magnitude of the multiplicity from the front end of the workpiece is determined according to the minimum allowable length, based on the cutting conditions, the length of the waste, after which a length from the front end of the waste rod is equal to the value of non-multiplicity. defined at the rear end of the bar, then the bar is cut into workpieces of measured length, and then a piece of waste is made from the side of the rear end of the workpiece, the length of which is equal to the magnitude of non-multiplicity determined at the front end of the bar. 2. A device for cutting and cutting to measured lengths of rolled metal, comprising a cutting mechanism with a cutting tool, a feed mechanism with position sensors for the workpiece, and an emphasis, characterized in that it is equipped with a waste removal mechanism made in the form of a failure window, the length of which is equal to the difference between half the distance from the vertical plane. passing through the cutting edge of the cutting tool of the cutting mechanism, to the stop and the size of the minimum end waste, the stop for determining the length of the cut workpiece is installed on the opposite side of the feed mechanism relative to the cutting plane with the possibility of adjusting its position, and the sensors are installed from each other at a distance equal to half the distance from the working end of the stop to the vertical plane passing through the cutting edge of the cutting tool of the cutting mechanism, with Ί In this case, the distance between the first and second sensors is increased in comparison with the rest by the value of the smallest length of the terminal waste. 4-4 Figure 2
