Abstract
The utility model discloses a pneumatic rear supporting device for a plate shearing machine, belonging to the field of auxiliary devices for shearing equipment. The pneumatic rear supporting device comprises a frame, wherein the frame is provided with a sliding plate; one side of the frame is provided with a support shaft; two parallel triangular brackets are arranged on the support shaft; upper and lower cylinders are arranged below the brackets; the bottom ends of the upper and lower cylinders are connected with the frame; piston rods at the upper ends of the upper and lower cylinders are hinged to the surfaces of the brackets; the brackets can be driven to rotate anticlockwise to horizontal positions around the support shaft by using the upper and lower cylinders; the upper side of each bracket is provided with a row of rollers; 5-20 rollers are provided; the distances between adjacent rollers are 10-50 centimeters. By adopting the device, plates can be prevented from being deformed in a shearing process, and the shearing accuracy is ensured.
Description
Technical field
The utility model belongs to the auxiliary equipment field of shearing equipment, more particularly, relates to the pneumatic rear materials supporting device of a kind of plate shearing machine.
Background technology
The sheet material that small-sized plate shearing machine general shear thickness is 0.5～4mm, when sheared length is while being 300～400mm with interior size, sheet material can be not sagging.But when size is greater than 500mm, thickness and is less than the sheet material of 1mm, sheet material can be sagging, makes to shear size inaccurate, and impact is produced.As shown in Figure 1, in figure, sheet material 5 is before shearing, in sag bent state.In this case, conventionally need to hold artificially sheet material, make it maintenance level, to production, bring huge inconvenience.
A kind of plate shearing machine knife rest of follow-up material-supporting, application number: 200520071180.9, the applying date: 2005-04-26, this utility model discloses the plate shearing machine knife rest of a kind of follow-up material-supporting belonging in plate shearing machine technical field, comprise tool holder body, the downside of tool holder body is provided with bed slide, in the tool holder body of bed slide side-lower, blade is installed, and the downside of described bed slide is provided with the channel-section steel of opening towards blade.In the utility model when work,, knife rest can follow-up material-supporting, and, when shear material not, channel-section steel can be held plate, when shearing, channel-section steel with the knife rest of plate shearing machine to lower swing and down motion is convenient to shear; When the first cutter is sheared end, channel-section steel tangles the plate cutting and moves upward with knife rest, makes the end of the plate cutting higher than the lower edge of aditus laryngis, and plate can be extracted out smoothly from aditus laryngis, then, then carries out next cutter shearing, until in cutting off completely.The utility model makes shear function shear smoothly overlength plate, is particularly useful on plate shearing machine that the aditus laryngis degree of depth is large.The weak point of this utility model is, the channel-section steel that is equivalent to retainer structure in this structure is fixedly installed on bed slide, and position is fixed and be unadjustable, so the sheet material after shearing still exists the problem that accuracy is not high.
