Description

The longeron aerofoil cutting tool of longeron roll shape production line

Technical field

The utility model belongs to vehicle frame and manufactures field, is specifically related to a kind of longeron aerofoil cutting tool of longeron roll shape production line.

Background technology

Aerofoil is sheared by hydraulic system and is driven 45 ° of shearing upper slitters, and extruding, cuts off longeron aerofoil downwards. Aerofoil shearing tool is divided into 2 of 45 ° of upper slitters, 4, lower cutter, and each two of front and back, 2, front lower cutter, is respectively left front lower cutter and right front lower cutter, and 2, rear lower cutter is respectively left back lower cutter and right back lower cutter.

As shown in Figure 1, 2, in prior art, load after cutter on equipment, produce when longeron, find that longeron tail end closes up, the most serious while especially shearing the large beam slab of 510L and 550L, while shearing the large beam slab of QSTE650 high-strength steel, longeron tail end root obviously closes up. Be two lower cuttves above on inspection and two lower cuttves below, the side on both sides is not on a horizontal plane, and front lower cutter is opened shelves and is significantly less than rear lower cutter and opens shelves, and every longeron of production all closes up seriously.

Summary of the invention

The object of this invention is to provide a kind of longeron aerofoil cutting tool of the longeron roll shape production line that can avoid aerofoil closing in.

For achieving the above object, the utility model provides following technical scheme: a kind of longeron aerofoil cutting tool of longeron roll shape production line, described longeron is channel-section steel shape, described cutting tool comprises the lower cutter that the aerofoil inner side of longeron arranges, and the upper slitter of longeron aerofoil arranged outside, described lower cutter is divided into front lower cutter and rear lower cutter, described front lower cutter and rear lower cutter space arrange, and the rear knife face of front lower cutter is concordant with the rake face of upper slitter, the rear lower rake face of cutter and the rear knife face of upper slitter are concordant, before described, the left and right sides of rear lower cutter are mutually concordant, and left and right sides are fitted with two aerofoil inner sides of longeron respectively,

Described upper slitter be divided into left and right two, and two upper slitters respectively in the longeron left and right sides along the oblique reciprocating motion of 45° angle, with under front and back cutter form shear action;

Described front lower cutter comprises again split type left front lower cutter and right front lower cutter; Rear lower cutter comprises again split type left back lower cutter and right back lower cutter;

The left and right sides of described forward and backward lower cutter are and draw shape setting in to longeron notch from the longeron outside of belly.

Technique effect of the present utility model is: the left and right sides of the forward and backward lower cutter in the utility model are concordant, and contacts with longeron aerofoil, has effectively avoided the closing in problem of aerofoil in shear history.

Detailed description of the invention

As Fig. 3, shown in 4, a kind of longeron aerofoil cutting tool of longeron roll shape production line, described longeron a is channel-section steel shape, described cutting tool comprises the lower cutter 20 that the aerofoil a2 inner side of longeron a arranges, and the upper slitter 10 of the aerofoil a2 arranged outside of longeron a, described lower cutter 20 is divided into front lower cutter 20a, 20b and rear lower cutter 20c, 20d, described front lower cutter 20a, 20b and rear lower cutter 20c, 20d space arranges, and front lower cutter 20a, the rear knife face of 20b is concordant with the rake face of upper slitter 10, rear lower cutter 20c, the rake face of 20d is concordant with the rear knife face of upper slitter 10, before described, rear lower cutter 20a, 20b, 20c, the left and right sides of 20d are mutually concordant, and left and right sides are fitted with the two aerofoil a2 inner sides of longeron a respectively. above-mentioned " forward and backward " direction limits and refers to: production line direction of feed is front, direction of feed be reversed rear. the left and right sides of the forward and backward lower cutter in the present invention are concordant, and contact with longeron aerofoil, avoid aerofoil a2 in shear history pushed by upper slitter 10 and produce closing in phenomenon.

Preferably, as shown in Figure 3, described upper slitter 10 be divided into left and right two, and two upper slitters 10 respectively in the longeron a left and right sides along the oblique reciprocating motion of 45° angle, form shear action with forward and backward lower cutter 20a, 20b, 20c, 20d.

Further, as shown in Figure 4, described front lower cutter 20a, 20b comprise again split type left front lower cutter 20a and right front lower cutter 20b; Rear lower cutter 20c, 20d comprise again split type left back lower cutter 20c and right back lower cutter 20d.

Further, as shown in Figure 3, the left and right sides of described forward and backward lower cutter 20a, 20b, 20c, 20d are and draw shape setting in to longeron a notch from the outside of belly a1 of longeron a. In the time shearing the longeron of QSTE650 high-strength steel material, in upper slitter withdrawing process, aerofoil a2 outwards can be pullled, produce micro-deformation, the gradient that increases lower cutter side is in order to allow aerofoil a2 produce inside deformation in the time shearing, with in and deformation when withdrawing, it should be noted that, this inside deformation is a kind of torsional deformation of trace, not closing in type deformation.
