这种机构可用来对压延型材、工字梁、钢轨等进行校直,也可用于轧辊车床的横向进给机构.它采用机械、液压增力传动的原理,使操作者减轻劳动强度,从而提高劳动生产率。如图示,本机构的本体2,可安装在轧辊车床的纵向拖板上.装在本体2上的活塞3、液压缸1作为横向进给的运动件.盖4用螺钉圈定在本体2上,它与丝杠8由平键6联接。螺母7与丝杠8啮合.手柄9与螺母7由键联成一体.手柄9旋转时,螺母7也同时旋转,使丝杠8及其头部的柱塞10压入活塞3的孔内.由于液压缸1的内孔面积大于活塞3的内孔面积,进给运动得以实现.
This mechanism can be used to align calender profiles, I-beams, rails, etc., as well as for the horizontal infeed of roll lathes. It uses mechanical, hydraulically powered transmissions to reduce operator effort and thereby increase Labor productivity. As shown in the figure, the main body 2 of this mechanism can be mounted on the longitudinal carriage of the roll lathe, the piston 3 mounted on the body 2 and the hydraulic cylinder 1 acting as a transverse feed member, and the lid 4 is fixed on the body 2 by a screw , Which is connected with the screw 8 by the flat key 6. The nut 7 is meshed with the screw 8. The handle 9 is integrated with the nut 7. When the handle 9 is rotated, the nut 7 is also rotated at the same time, so that the screw 8 and the plunger 10 at its head are pressed into the hole of the piston 3. Thanks to the fact that the inner bore area of the hydraulic cylinder 1 is larger than the inner bore area of the piston 3, the feed movement is achieved.
