Flying shearing machine
Technical field
The invention belongs to metallurgical steel rolling equipment technical field, be specifically related to a kind of flying shearing machine.
Background technology
On steel rolling equipment line in metallurgy industry, milling train carries out continuous rolling to stock, makes steel embryo forming, but in the operation of rolling due to rolled piece head-tail cracking, out-of-flatness or deformation of rolled wire, easily there is heap steel accident; This just need to carry out cutting head cutting tail to rolled piece.In the time that flying shearing machine are sheared, rolled piece arrives flying shearing machine shearing place by guide groove movement, now because the bar rolling speed ratio of wire rod line is very fast, if rolled piece head-tail out-of-flatness, or deformation of rolled wire, general wire rod flying shearing machine are cut arm configuration and can be caused flying shearing machine can not normally shear rolled piece, easily cause piling the generation of steel accident.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of flying shearing machine, not only overcome rolled piece in traditional flying shearing machine shear history due to higher, the on the low side defect that causes occurring heap steel accident of elbow or rolled piece position, and promote the lumber recovery of steel, improve the output of steel mill, the maintenance cost of reduction equipment, has realized high accuracy shearing.
Technical scheme: for achieving the above object, the present invention adopts following technical scheme:
Flying shearing machine, comprise flying shearing machine body, are provided with upper shear arm and lower shear arm on flying shearing machine body, are provided with upper guide plate at the feed side of described upper shear arm, are provided with bottom guide at the feed side of described lower shear arm, and upper guide plate and bottom guide are arc surface structure; On described upper shear arm and lower shear arm, be provided with respectively the cutting edge for cutting, cutting edge is fixed by briquetting respectively; On upper shear arm, be arranged between upper guide plate and cutting edge for fixing briquetting; On lower shear arm, cutting edge is arranged between bottom guide and briquetting; After cooperation, between upper guide plate and bottom guide, form diminishing charging aperture, until join with cutting edge.
The working face of upper guide plate is the smooth pre-pressure surface of circular arc, and supplied materials is carried out to precompressed processing; The working face of bottom guide is that smooth circular arc is lifted face in advance, and supplied materials is lifted to processing in advance; The arc surface of upper guide plate and the arc surface of bottom guide are symmetrical arranged, and after cooperation, the two forms diminishing charging aperture, until join with cutting edge.
Described upper shear arm and lower shear arm are by being arranged on flying shearing machine body for the keyway of fixedly cutting arm.
On described upper shear arm and lower shear arm, be reserved with the screwed hole for briquetting and cutting edge are installed, described briquetting and cutting edge are bolted on upper shear arm and lower shear arm.
Described upper guide plate is bolted on upper shear arm, and bottom guide is bolted on lower shear arm.
Beneficial effect: compared with prior art, flying shearing machine of the present invention are by arranging upper guide plate and bottom guide is processed supplied materials in advance, can prevent that heap steel phenomenon from appearring in rolled piece in the time shearing, also make the rolled piece broken end under shearing fall into smoothly waste material collection device simultaneously, do not affect the normal shearing of next flying shearing machine, improve the lumber recovery of steel, reduce production loss, the maintenance cost of reduction equipment, meet the instructions for use of flying shearing machine, ensure the normal operation on steel rolling equipment line, there is good practicality.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As shown in Figure 1, a kind of flying shearing machine, comprise flying shearing machine body 1, upper shear arm 2, pressing plate 3, cutting edge 4, lower shear arm 5, upper guide plate 6 and bottom guide 7, on flying shearing machine body 1, be provided with upper shear arm 2 and lower shear arm 5, be provided with upper guide plate 6 at the feed side of upper shear arm 2, be provided with bottom guide 7 at the feed side of lower shear arm 5, be provided with respectively the cutting edge 4 for cutting on upper shear arm 2 and lower shear arm 5, cutting edge 4 is fixing by briquetting 3 respectively; On upper shear arm 2, be arranged between upper guide plate 6 and cutting edge 4 for fixing briquetting 3; On lower shear arm 5, cutting edge 4 is arranged between bottom guide 7 and briquetting 3.After cooperation, between two cutting edges 4, form the space of cutting.
As shown in Fig. 2 ~ 3, upper guide plate 6 and bottom guide 7 are two boards respectively, and one is arc working plate, and one is L-type fixed head; The working plate of upper guide plate 6 is the smooth pre-pressure surface of circular arc, and supplied materials is carried out to precompressed processing; The working plate of bottom guide 7 is that smooth circular arc is lifted face in advance, and supplied materials is lifted to processing in advance; The arc surface of the arc surface of upper guide plate 6 and bottom guide 7 is symmetrical arranged, and after cooperation, the two forms diminishing charging aperture, until join with cutting edge 4.
Upper shear arm 2 and lower shear arm 5 are by being arranged on flying shearing machine body 1 for the keyway of fixedly cutting arm; On upper shear arm 2 and lower shear arm 5, be reserved with the screwed hole for briquetting 3 and cutting edge 4 are installed, briquetting 3 and cutting edge 4 are bolted on upper shear arm 2 and lower shear arm 5; Upper guide plate 6 is bolted on upper shear arm 2, and bottom guide 7 is bolted on lower shear arm 5.
The course of work: this flying shearing machine shear history is high-speed rod shear mode, in the time that workpiece motion s arrives flying shearing machine shearing place, upper guide plate 6 is depressed processing in advance to the head of rolled piece in advance, make rolled piece can correct smoothly movement position, ensure the stationarity of shearing, in the time that rolled piece afterbody moves to flying shearing machine shearing place, bottom guide 7 carries on processing in advance to rolled piece in advance simultaneously, ensures the shear height of rolled piece afterbody; Between one pressure one is lifted, avoid due to higher, the on the low side defect that causes occurring heap steel accident of elbow or rolled piece position; , by the globoidal structure of upper guide plate 6 and bottom guide 7, the broken end after shearing is guided meanwhile, make it fall into smoothly waste material collection device and go, do not affect the normal shearing of next flying shearing machine.
