Description
Technical field
The present invention relates to sheet metal is carried out the forging equipment of bending machining---three rolls plate bending machine, be specifically related to the three rolls plate bending machine of the adjustable in the horizontal direction and following roller strap backing roll of two lower roll centre-to-centre spacing.
Background technology
Existing two lower roll centre-to-centre spacing are adjustable in the horizontal direction and the three rolls plate bending machine of following roller strap backing roll has two kinds of forms, a kind of is that two lower rolls and backing roll are adjusted the centre-to-centre spacing of two lower rolls respectively in the horizontal direction by two cover hydraulic pressure or mechanical actuation device, and controls the parallel of two lower rolls.The advantage of this form is easy to adjust, the automatization level height, and be stepless adjustment; Shortcoming is that the parallel accuracy of two rollers is relatively poor, and the error of two cover drive units may superpose in the same way, and two lower rolls can not be fully synchronously in moving, and workpiece and roll surface have the possibility that slides over each other, and the horizontal component that every cover drive unit bears is bigger, can not cancel each other.The characteristics of this form are that the adjustment of two lower roll centre-to-centre spacing and two lower rolls moving horizontally when pre-bending move horizontally drive unit by two covers respectively and carry out simultaneously.
Second kind is moving or the adjustment of lower roll centre-to-centre spacing of the horizontal direction of two lower rolls when carrying out pre-bending by the mechanical or manual horizontal drive apparatus of same set of hydraulic pressure, two lower rolls and back-up chock are made up of two parts, two parts bearing block is linked together by threaded pull bar and nut and carries out moving of horizontal direction, by nut, adjust the centre-to-centre spacing that cushion block and horizontal drive apparatus are adjusted two lower rolls and backing roll, the adjustment of two lower roll centre-to-centre spacing has level.The characteristics of this form are to horizontal down-regulation type 3-roller lapping machine, the adjustment of two lower roll centre-to-centre spacing and two lower rolls moving horizontally when pre-bending is separately to carry out, adjust two lower roll centre-to-centre spacing earlier, and two lower rolls and back-up chock are linked together moving of horizontal direction when carrying out pre-bending, adjust moving of two lower roll centre-to-centre spacing and the horizontal direction of two lower rolls when carrying out pre-bending and carry out, but the power when adjusting two lower roll centre-to-centre spacing is carried out by the same set of drive unit that moves horizontally by the different device of two covers.The advantage of this form is that the parallel accuracy of two rollers is better, and what workpiece and roll surface slided over each other is possible less, and it is less to move horizontally the horizontal component that drive unit bears, and can cancel each other; Shortcoming is that the automatization level of adjusting is low.
