摘要： PURPOSE:To reduce the scattering of the cut length of a work from the cut length set, by numerically controlling the cut length. CONSTITUTION:In the dimension control for a shearing machine in which a workpiece and a tool rest equipped with a cutting edge, the both feed speeds are made equal by always keeping constant the difference between the feed per stroke of the workpiece and the feed per stroke of the tool rest after cutting instruction signal is generated. The cut length of the work is determinded according to the length of the work which travels during the time when the cutting instruction signal (b) generated by the first counter 11 is generated. The work can be cut with high accuracy into the length set on a cut-length setting device 12 connected to the first counter 11.

摘要： PURPOSE:To prevent generation of dimples on cutting by applying previous cut onto a pipe, before an upper blade for regular cutting bites-into the pipe, so as to form a previous cut part onto the part of the pipe which is supposed to be bitten by the upper blade by means of a top knife which turns on the pipe. CONSTITUTION:A top knife 2 is turned around a pipe A by turning a crank arm 10 by a crank link (not shown in the figure), and a cut part is formed on the part of the pipe whigh is supposed to be bitten by an upper blade. The amount of cut-in by the top knife 2 is set about 1/3 of the thickness of the pipe A, and the width of cut by the top knife 2 is made a little larger than the thickness of the upper blade 1. Then, regular cut is carried out.
摘要翻译：目的：为了防止在切割时产生凹坑，在将上一次切割加工到管道上之前，在用于常规切割的上刀片进入管道之前，以便将之前的切割部分形成在应该被咬的管道部分上通过上刀，通过打开管道的顶刀。构成：顶部刀2通过曲柄连杆（图中未示出）转动曲柄臂10而绕管A转动，并且切割部分形成在管道的一部分被假定被上刀片顶刀2的切入量设定为管A的厚度的1/3左右，上刀2的切割宽度比上刀1的厚度稍大。然后，进行定期切割。

摘要： PURPOSE:To contrive the mass-production of a halving joint member by providing predetermined folded edges respectively on the both side ends of a coil material to form a halving joint while continuously supplying the coil material said halving joint member and simultaneously cutting it in order. CONSTITUTION:Folded edges are provided on the side edgrs (a), (b) of a supplied coil material with a molding roll, etc., and a halving joint member A is formed. Said halving joint A member is transferred to and introduced into a cutting device as it is, and a die 5 having shapes in accord with those of the faces O, P of the side edge (a) is pressed to said halving joint member from the outside, and simultaneously a cutter 3 is pulled to the side. Using blade parts 3b, 3c, 3d, the faces P and O are cut at a stroke into the same shape, and thereby the cutting strain and burr, etc., of the side edge (a) can be certainly prevented, permitting the mass-production.
