摘要： PURPOSE:To sufficiently lubricate the contact part of rolls without intermixing a lubricant into cooling water by sealing between a work roll, a back-up roll and a header block with a sealing means provided on the header block and recovering an excessive lubricant. CONSTITUTION:In this rolling device using a work roll crossing mill, a lubricant feeding system 104 is provided between the work roll 2 and the back-up roll 3. The lubricant fed between the rolls is sealed with a contact seal provided on the header block. The contact seal is rotatably connected so as to follow up the cross angle of the work roll 2 with the joining pin of the header block on the back-up roll side with the header block on the work roll side. A nozzle with which the fluid is outward jetted is embeded in the side face of the tip part of the header block on the back-up roll side. Thus, the lubrication in the contact part of roll is sufficiently executed without incorporating the lubricant between rolls in a roll cooling water. Also, the lubricant feeding means can follow up the change of the crossing angle of the work roll with an adjusting means.

摘要： PURPOSE:To previously detect a fault in the main parts of a sizing press device and to prevent an accident by detecting the loaded state and movement of the parts and performing calculation after inputting detecting signals, and then, deciding a calculated result. CONSTITUTION:A fixed correlative relation exists among the loads FWi applied to respective supporting wheel 4 and 5 of an inner and outer blocks 3 and 6 of the pressing force FPi and torque T applied to four screws 8, clank position alpha, and a width rolling reduction DELTAW when a sizing pressing device makes normal width rolling reduction works. Therefore, the expression of the correlative relation is found beforehand by always measuring the force and torque. The expression thus found is used in an arithmetic circuit 17 and a calculated result of the circuit is compared with a value obtained in a normal operating state at a deciding circuit 18. When the difference between the calculated result and reference value exceeds an allowable value, the state is decided as abnormal and an abnormal signal is outputted from an alarming device 19. Therefore, the operator of this machine can detects a faulty state before an accident occurs and can make appropriate maintenance works.

摘要： PURPOSE:To improve the lubricating effect between rolls and to reduce the roll thrust by sealing the roll space between each work roll and the coping backup roll to injection and dispersion of work roll coolant and supplying lubricant between the rolls. CONSTITUTION:A sealing device by which the boundaries between the work rolls 1 and the coping backup rolls 3 are separated from areas injecting and dispersing work roll coolant and devices supplying lubricant between the rolls are equipped. A seal plate 7 having a square slot small in width compared with the roll diameter over all the length of the barrel of the work roll and provided with a seal lip to the circumferential surface and the end face of a roll barrel on the inner edge of this slot is equipped between the right and left chocks of each work roll. The bottom periphery of a cover 8 enclosing a support roll of the work roll 1 is pressed against and contacted with a seal plate 7 to form a closed space separated from infection and dispersion of the work roll coolant. In this way, the practicability of rolling can be accomplished profitably.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for bonding a metal plate with which sufficient bonding strength is obtained in a short time.
SOLUTION: An upper shearing blade 3 having a triangular columnar projecting part 30 and a lower shearing blade 4 having a projecting part 40 are applied to the overlapped part of the metal plates 1, 2 to be bonded and pressed into the part obliquely in the thickness direction and by a stroke in such a range that the metal plates 1, 2 are not completely cut off. The operating loci of the upper shearing blade 3 and the lower shearing blade 4 are overlapped so that one falls inside the other shearing blade, the bonding portions are formed by plastic flow deformation with the sheared surfaces of the metal plates 1, 2. At this time, because compressive force acts on the portion to be bonded where is enclosed by the amount of overlap and the compressed portion when the bonding is completed is contracted, the bonding strength is enhanced. Since the projecting parts 30, 40 of the shearing blades produces pressing force by which the sheared surfaces are pressed each other from the slopes, the compressive force which acts on the bonding portion is enhanced.

摘要翻译：要解决的问题：提供一种在短时间内获得足够的结合强度的金属板的接合装置。解决方案：将具有三角形柱状突起部分30和具有突出部分40的下剪切刀片4的上剪切刀片3施加到金属板1,2的重叠部分，以被粘合并被倾斜地压入该部分在厚度方向上和在金属板1,2没有完全切断的范围内的行程。上剪切刀片3和下剪切刀片4的操作轨迹重叠，使得一个落在另一个剪切刀片内，粘合部分由金属板1,2的剪切表面的塑性流动变形形成。在此时间，因为压缩力作用在被重叠的部分包围的被粘合部分上，并且当接合完成时压缩部分收缩，所以粘结强度提高。由于剪切刀片的突出部分30,40产生挤压力，通过该压力，剪切表面从斜面彼此挤压，作用在粘结部分上的压缩力增强。版权所有（C）2008，JPO＆INPIT
