Abstract
The utility model discloses a rolling-type back baffle device of a plate shearing machine. The rolling-type back baffle device comprises a sliding block (5), a screw rod (8), and a guiding shaft (11) and is characterized in that the sliding block (5) is internally provided with two nuts, namely a fixed nut (6) and a moving nut (1), for automatically regulating a ball screw pair, the fixed nut (6) and the moving nut (1) are supported by using a compression spring (4) and matched with the screw rod (8) and cannot move axially so that idle stroke of the screw rod (8) during positive and negative reversing is eliminated; and the rectangular guiding shaft (11) penetrates among a plurality of single-row radial ball bearings (9) on the sliding block (5), and once the rectangular guiding shaft (11) is worn and a fit clearance is overlarge, the clearance can be eliminated only by regulating and rotating a small eccentric shaft (12). The rolling-type back baffle device disclosed by the utility model has the advantages of simple structure, low production cost, easiness for users to mount and regulate, strong practicability and the like, can be used for effectively reducing friction resistance and improving dimensional precision of shorn materials by regulating the clearance generated after wears are eliminated, and can be widely applied to plate shearing machines and bending machines.
Description
Affiliated technical field
The invention relates to plate shearing machine, particularly relates to a kind of plate shearing machine roller rear material stopping device.
Background technology
General plate shearing machine rear material stopping device is combined by screw pair and rail plate pair, and there is the phenomenon that frictional resistance is big, guide rail weares and teares easily in use in this rear material stopping device, and the gap that wearing and tearing produce can't be adjusted.At present, a kind of plate shearing machine rear material stopping device that adopts ball screw assembly, and spherical guide to form appears, it has reduced frictional force, but the gap user that wearing and tearing produce still can't adjust, in case fit clearance is excessive, both influence the dimensional accuracy of shearing material, also increased number of times and the workload that material is cut in examination, wasted material.
Summary of the invention
The invention technical problem to be solved is: have the problem that frictional resistance is big, fit clearance can't be adjusted in use at above-mentioned rear material stopping device, invented a kind of plate shearing machine roller rear material stopping device, it can reduce frictional resistance effectively, and can adjust fit clearance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of plate shearing machine roller rear material stopping device, comprise slide block, hold-down nut, screw, traveling nut, holding screw, clamp nut, the compression spring, leading screw, the axis of guide, the screw cover, eccentric little axle, single-row radial ball bearing, lock-screw, it is characterized in that, two on automatic adjustment ball screw assembly, nut is housed in the slide block, wherein a hold-down nut is fixed on the slide block, another is the traveling nut that is shaped on groove on the external diameter, it is contained in the slider bore, there is holding screw to be stuck in the groove of traveling nut on the slide block, supportting with the compression spring between hold-down nut and the traveling nut, like this, hold-down nut on the slide block and traveling nut cooperate with leading screw, axially can not go here and there idle stroke when having eliminated the positive decommuntation of leading screw; Also be drilled with many pilot holes on the slide block, screw cover, eccentric little axle, single-row radial ball bearing are housed in the hole, and the rectangle axis of guide just is through between several the single-row radial ball bearing external diameters on the slide block, in case axis of guide wearing and tearing, fit clearance is excessive, just can eliminate the gap as long as adjust the eccentric little axle of rotation.
The beneficial effects of the utility model are, can reduce frictional resistance effectively, can eliminate the gap that the wearing and tearing back produces by adjusting, and improve the dimensional accuracy of shearing material, reduce number of times and workload that material is cut in examination, have saved material.It has simple in structure, production cost is low, the user is easy to install to adjust, characteristics such as practical, can be widely used in plate shearing machine, bender.
