Description

Clod wash corrugated plating shear

Technical field

The utility model relates to corrugated plating production field, refers to a kind of clod wash corrugated plating shear particularly.

Background technology

The most of thickness of corrugated product, at below 1mm, is usually divided into continuous seepage and is interrupted and produce, being interrupted the monolithic raw material produced as having sheared, do not need cut-out equipment, and continuous seepage being coil of strip due to raw material, needing special cut-out equipment.Along with the raising increasing progressively and require product quality of market individual demand, the thickness of subwave card reaches 4mm, and requiring during production can fast shut-off online, and product end mass can be ensured, sizing accuracy requirement ± 1.5mm, cutting section impulse-free robustness, cutting rearward end is without distortion.And common shear-blade, cutting rearward end is of poor quality, and when product thickness reaches 2-4mm, blade strength and life-span obviously decline, sizing accuracy is deteriorated, and reach ± 3mm, and cutting section is jagged, the most seriously product Leading Edge Deformation, specifically see Fig. 1, can not meet the instructions for use of client.

Utility model content

The purpose of this utility model is exactly will provide a kind of and ensure that end mass requires, sizing accuracy is high, ensure blade strength and life-span and the clod wash corrugated plating shear of Burr Problem after product can be avoided to cut.

For achieving the above object, clod wash corrugated plating shear designed by the utility model, comprise the cut-out support that power is provided by petrol station, described cut-out support is provided with cutter and bottom knife, described cutter and bottom knife form by multiple edge of a knife, described cutter is consistent with product section with each edge of a knife shape of bottom knife, the circular arc of to be radius be the angle bottom each edge of a knife of described cutter R, the corresponding position of each edge of a knife of described bottom knife is angular shape, and the oil cylinder of described cut-out support is multiple.

Preferably, described cutter and bottom knife are materials is 4Cr5MoSiV1, quenching technical is the blade of HRC56 ± 2.

Further, the axis direction of described cutter is horizontal by certain angle α.

Also further, described angle α=2 °.

Again further, the longitudinal cross-section of described cutter and bottom knife is horizontal by certain angle β.

Further, described angle β=93 °.

Further, bottom each edge of a knife of described cutter, the value of arc radius R is equal with the corrugated plating thickness that will cut off.

Further, arc radius R=1 ~ 4mm.

Further, the oil cylinder of described cut-out support is two.

Operation principle of the present utility model is such:

(1) improve blade material and Technology for Heating Processing, improve blade strength;

(2) according to scissors principle and shape of product feature, and product Leading Edge Deformation amount, shearing inclination reasonable in design;

(3) blade is designed to the section being with certain angle, also will ensures intensity when blade reverse complex shears is cut simultaneously;

(4) the circular arc place that cutter and bottom knife contact with product adopts different designs, reduces the circular arc distortion caused because of shearing;

(5) for meeting the shearing force of thickness 2-4mm product, single oil cylinder being changed into two oil cylinder, increasing shearing force.

In sum, the utility model has the advantage of: this cover corrugated plating shear-blade, thickness can be met and use at the product of 1 ~ 4mm, different cut lengths, online fast shut-off can be realized.After cut-out, product end mass meets technical requirement, the basic impulse-free robustness in product termination, and can ensure sizing accuracy requirement ± 1.5mm, and cutting rearward end is without distortion.Other products blade adopts same mentality of designing, and shear effect is also very good.
