Description

Technical Field

[0001] The utility model relates to the field of metallurgical technology, and more specifically, to a swing-type flying shear guide groove device. Background Art

[0002] Flying shear is an important equipment used by steel enterprises to shear metal billets. It can cut the head and tail of rolled pieces and break them by accident. There are many types of flying shears, including crank-connecting rod flying shears, rotary flying shears, disc flying shears, swing flying shears, etc.

[0003] At present, in order to ensure that the rolled piece can smoothly enter the subsequent processing station after passing through the flying shear, guide grooves that play a supporting and guiding role are usually arranged at the entrance and exit of the flying shear respectively. Among them, the guide groove located at the exit of the flying shear plays a vital role in the success of the shearing of the flying shear equipment. After the flying shear cuts the head and tail of the rolled piece, the removed rolled piece should fall into the material box under the guide groove, and the main part of the rolled piece should enter the guide groove and continue to move along the guide groove to the subsequent station.

[0004] However, since the head and tail of the cut piece fall only by gravity after shearing, the falling trajectory is approximately a parabola. As the rolling speed increases, the horizontal velocity of the cut piece head and tail also increases accordingly, causing the head and tail of the piece that should fall into the material box to easily rush into the flying shear outlet guide groove, causing production accidents such as steel accumulation and equipment damage. In addition, the shearing speed of the multi-cut flying shear is high, and multiple pieces are sheared at the same time. How to ensure that the cut piece enters the material box smoothly and the main body of the piece enters the flying shear outlet guide groove smoothly is a technical problem that needs to be solved urgently.

[0025] In order to solve the problems existing in the existing flying shears during the shearing process, such as the head and tail of the rolled piece that should fall into the material box can easily rush into the flying shear outlet guide groove to cause steel piling and equipment damage, etc., the utility model provides a flying shear guide groove device, and a telescopic cylinder is arranged below the main groove. The telescopic cylinder can drive the auxiliary guide groove to swing up and down relative to the main groove, and then the swinging auxiliary guide groove is used to block the shearing waste of the steel billet to be processed outside the guide groove, and the waste is knocked into the material box when the auxiliary guide groove falls; when the auxiliary guide groove is parallel to the main groove, the steel billet to be processed can smoothly pass through the auxiliary guide groove into the main groove, which can effectively avoid the phenomenon of steel piling at the cutting head and tail and after accidental breakage of the flying shear, and improve the stability of the multi-cutting flying shear equipment.

[0026] In order to describe the structure of the flying shear guide groove device of the present invention in detail, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Figure 1 The schematic structure of the flying shear guide groove device according to the embodiment of the utility model is shown.

[0028] like Figure 1 As shown, the flying shear guide groove device of the embodiment of the utility model comprises a main groove 2 and an auxiliary guide groove 1 which is arranged at one end of the main groove 2 and hinged with the main groove 2; wherein, a telescopic cylinder 3 is arranged below the main groove 2, and the extension and contraction of the telescopic cylinder 3 can drive the auxiliary guide groove 1 to swing up and down relative to the main groove 2; and then when the auxiliary guide groove 1 swings relative to the main groove 2, the sheared waste of the steel billet to be processed falls into the material box under the obstruction of the auxiliary guide groove 1; and when the auxiliary guide groove 1 is parallel to the main groove 2, the main part of the steel billet to be processed enters the main groove 2 through the auxiliary guide groove 1, thereby preventing the waste from entering the guide groove, and can be suitable for the processing scenarios of multi-cutting flying shears.

[0029] In order to achieve the effect of driving the auxiliary guide groove 1 to swing up and down by the telescopic cylinder 3, a vertically distributed push plate 5 can be arranged below the auxiliary guide groove 1, that is, a push plate 5 fixedly connected to the auxiliary guide groove 1 is arranged below the auxiliary guide groove 1, and the setting direction of the push plate 5 is perpendicular to the extension direction of the auxiliary guide groove 1, and the end of the piston rod 31 of the telescopic cylinder 3 is movably connected to the push plate 5. Figure 2 In the illustrated embodiment, hinge holes are respectively provided on the end of the piston rod 31 and the push plate 5, and the end of the piston rod 31 is movably connected to the push plate 5 via the hinge hole and a hinge 6 matched with the hinge hole; that is, when the piston rod 31 is extended or retracted, the auxiliary guide groove 1 can be driven by the push plate 5 to swing upward or downward.

[0030] Since the end of the piston rod 31 of the telescopic cylinder 3 is movably connected to the push plate 5, the angle formed between the piston rod 31 of the telescopic cylinder 3 and the push plate 5 is not fixed. In specific applications, a desired angle can be formed between the piston rod 31 of the telescopic cylinder 3 and the push plate 5 according to actual needs.

[0031] In a specific embodiment of the present invention, a hinge extension portion and a hinge hole arranged on the hinge extension portion may be respectively provided at the tail portion of the main guide groove 2 and the head portion of the auxiliary guide groove 1. The hinge holes on the main guide groove 2 and the auxiliary guide groove 1 are movably connected via a hinge connector. When the telescopic cylinder 3 is extended or retracted, the auxiliary guide groove 1 can swing up and down relative to the main guide groove 2 under the action of the hinge.

[0032] In order to prevent the auxiliary guide groove 1 from colliding with the main guide groove 2 when it swings upward, in the flying shear guide groove device of the present application, a first inclined surface can be set at the tail of the main guide groove 2, and a second inclined surface can be set at the head of the auxiliary guide groove 1. The positions of the first inclined surface and the second inclined surface correspond to each other. When the auxiliary guide groove 1 swings upward relative to the main guide groove 2, the ends of the main guide groove 2 and the auxiliary guide groove 1 can avoid each other through the first inclined surface and the second inclined surface. In addition, an inclined feed port can be set at the tail of the auxiliary guide groove 1. The specific inclination angles of the above-mentioned inclined surfaces can be set according to the swing amplitude of the auxiliary guide groove 1, and are not limited to the specific structure shown in the accompanying drawings.

[0033] It can be known that, in the application process of the flying shear guide groove device of the utility model, when it is necessary to shear the head of the steel billet to be processed, that is, before the steel billet to be processed enters the auxiliary guide groove 1, it is necessary to shear the head of the steel billet to be processed by the flying shear. At this time, before the flying shear shears the head, the auxiliary guide groove 1 can be controlled by the telescopic cylinder 3 to swing upward a certain angle relative to the main groove 2. At this time, the angle between the auxiliary guide groove 1 and the main groove 2 is less than 180 degrees. Due to the upward swing of the auxiliary guide groove 1, the head waste can be prevented from entering the auxiliary guide groove 1; and after the flying shear shears the head, the auxiliary guide groove 1 can be controlled by the telescopic cylinder 3 to swing downward relative to the main groove 2, and the head waste can be knocked into the waste box by the downward swinging auxiliary guide groove 1, and at the same time, the auxiliary guide groove 1 is made parallel to the main groove 2, and the steel billet to be processed after the head is removed can smoothly enter the auxiliary guide groove 1 and the main groove 2.

[0034] In addition, after the steel billet to be processed passes through the auxiliary guide groove 1 and the main groove 2, the tail of the steel billet to be processed needs to be sheared. At this time, after the flying shear shears the tail, the auxiliary guide groove 1 can be controlled by the telescopic cylinder 3 to swing upward relative to the main groove 2, so that the angle between the auxiliary guide groove 1 and the main groove 2 is less than 180 degrees, so that the tail waste after shearing is blocked in front of the auxiliary guide groove 1, and then the auxiliary guide groove 1 is quickly controlled to swing down to knock the tail waste into the waste box.

[0035] In another embodiment, when the tail of the steel billet to be processed is sheared, after the flying shear shears the tail, the auxiliary guide groove 1 can also be controlled by the telescopic cylinder 3 to swing downward relative to the main groove 2. At this time, the angle between the auxiliary guide groove 1 and the main groove 2 is greater than 180 degrees. In this embodiment, the auxiliary guide groove 1 swinging downward relative to the horizontal direction can also prevent the tail waste from entering the auxiliary guide groove 1. At the same time, the auxiliary guide groove 1 set downwardly tilted can also make some waste that has entered the auxiliary guide groove 1 automatically slide down under the action of gravity to prevent it from further entering the main groove 2.

[0036] It should be noted that in the flying shear guide groove device of the present invention, the incoming direction of the steel billet to be processed is from the auxiliary guide groove 1 to the main guide groove 2, that is, the direction indicated by the arrow in the accompanying drawing, and the flying shear for shearing the steel billet to be processed is arranged on the right side of the auxiliary guide groove 1.

[0037] By utilizing the above-mentioned flying shear guide groove device, a telescopic cylinder is arranged below the main groove, and the auxiliary guide groove is driven to swing up and down relative to the main groove by the extension and contraction of the telescopic cylinder, so that the sheared waste of the steel billet to be processed is blocked outside the guide groove by the swinging auxiliary guide groove, and the waste is knocked into the material box when the auxiliary guide groove falls. When the auxiliary guide groove is parallel to the main groove, the steel billet to be processed can smoothly pass through the auxiliary guide groove into the main groove, and the waste can be prevented from rushing into the guide groove by swinging, and the waste can be knocked down to accelerate the falling speed, which effectively avoids the phenomenon of steel piling at the cutting head and tail and after accidental breakage of the flying shear, improves the stability of multi-cutting flying shear equipment, reduces production accidents, avoids equipment damage, and increases equipment service life.

[0038] As described above, the flying shear guide groove device according to the utility model is described by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various improvements can be made to the flying shear guide groove device proposed by the utility model without departing from the content of the utility model.
