Description

Technical Field

[0001] The present invention relates to the technical field of steel plate shearing and output equipment, and particularly to a steel plate edge trimming and output device and a steel plate edge trimming and output method. Background Art

[0002] The circular shear is one of the important equipment on the sheet production line. It shears both sides in the width direction of the steel plate to make the width of the steel plate meet the requirements. When performing sizing shearing on the width of the steel plate, the generated edge trimmings need to be sheared by a matching shredding knife into edge trimmings with a width of 30 mm - 80 mm and a length of about 250 mm. After being shredded, the edge trimmings need to be transported out of the production line by an edge trimming output device. There are many types of edge trimming output devices, such as belt transportation chain type, steel transportation chain type, etc. Such output devices all require a transfer site with one in use and one standby for the hopper, the transportation chain must always be running, the length of the transportation chain reaches 20 meters, and the edge trimmings are also easily stuck in the transportation chain.

[0003] Based on this, the present invention proposes a steel plate edge trimming and output device and a steel plate edge trimming and output method to achieve high-efficiency output of steel plate edge trimmings after the circular shear. Summary of the Invention

[0004] In view of the above technical problems, the present invention overcomes the shortcomings of the prior art and provides a steel plate edge trimming and output device and a steel plate edge trimming and output method, which can conveniently control the synchronous retraction and extension of two baffles. Combined with the design of a hoisting device, a fixed pulley device and a hoisting steel wire rope, the two states of steel plate edge trimming output / temporary storage can be quickly switched, greatly improving the efficiency of steel plate shearing and output.

[0005] In a first aspect, the present invention proposes a steel plate edge trimming and output device, which specifically includes a lower hopper and an upper hopper connected above it. The projection surface of the upper hopper in the direction of gravity and the projection surface of the lower hopper in the direction of gravity have a non-overlapping area, so that the moving side edge trimmings and the fixed side edge trimmings respectively free-fall onto the upper hopper and the lower hopper. The discharge ports of the upper hopper and the lower hopper are respectively hinged with an upper baffle and a lower baffle, and an upper and lower baffle connecting rod is also hinged between the parallel upper baffle and the lower baffle, so that the upper baffle and the lower baffle deflect synchronously. A cylinder and a pressure wheel device are also arranged on the lower hopper. The telescopic end of the cylinder is connected with a pressure wheel steel wire rope, and this pressure wheel steel wire rope passes through the pressure wheel device and then is connected to the lower baffle. When the cylinder retracts the pressure wheel steel wire rope, the lower baffle deflects to the vertical state, and when the cylinder extends the pressure wheel steel wire rope, the lower baffle deflects to the horizontal state under the action of gravity.

[0006] Furthermore, the bottom of the lower hopper is hinged with a base, so that the lower hopper can deflect at an angle on the base around the support point of the lower hopper.

[0007] Further, it further includes a hoisting device and a fixed pulley device. The hoisting device winds and unwinds a hoisting steel wire rope. The hoisting steel wire rope passes through the fixed pulley device and is connected to the lower hopper, so that the hoisting device winds and unwinds the hoisting steel wire rope to drive the lower hopper to deflect on the base.

[0008] Further, a first lower trimming guide plate and a second lower trimming guide plate are connected to the lower hopper to guide the fixed side trimming falling on the lower hopper to the discharge port of the lower hopper, and the discharge ports of the lower hopper and the upper hopper do not overlap in the vertical direction.

[0009] Further, baffles are arranged on both sides of the upper hopper and / or the lower hopper.

[0010] Further, it further includes a steel plate cutting head collecting hopper located below the discharge ports of the upper hopper and the lower hopper.

[0011] In a second aspect, the present invention also proposes a method for outputting steel plate trimming, using the aforementioned steel plate trimming output device, which specifically further includes: When the steel plate trimming is normally produced and output, the hoisting device retracts the hoisting steel wire rope to control the lower hopper to rotate and tilt around the support point of the lower hopper, raising the tail end of the lower hopper. The air cylinder extends the press wheel steel wire rope to make the lower baffle in a horizontal state or an inclined downward state. The moving side trimming and the fixed side trimming respectively fall freely onto the inclined upper hopper and the lower hopper and slide out from their respective discharge ports. When the steel plate trimming is normally produced but not output, the hoisting device loosens the hoisting steel wire rope to control the lower hopper to rotate to a horizontal state around the support point of the lower hopper. The air cylinder retracts the press wheel steel wire rope to retract the lower baffle to a vertical state. The moving side trimming and the fixed side trimming respectively fall freely onto the horizontal upper hopper and the lower hopper and are temporarily stored.

[0012] Further, when the moving side trimming and the fixed side trimming respectively fall freely onto the upper hopper and the lower hopper, the first lower trimming guide plate and the second lower trimming guide plate guide the fixed side trimming falling on the lower hopper to the discharge port of the lower hopper, and the moving side trimming and the fixed side trimming of the upper hopper and the lower hopper are respectively output to different positions.

[0013] The beneficial effects of the present invention are: (1) When the steel plate trimming output device of the present invention is normally producing and outputting the steel plate trimming, the moving side trimming and the fixed side trimming can respectively fall freely onto the inclined upper hopper and the lower hopper and slide out from their respective discharge ports to different positions, realizing the orderly classified output of the moving side trimming and the fixed side trimming. (2)When the steel plate edge cutting output device of the present invention is in normal production but does not output, by controlling the deflection angles of the upper hopper and the lower hopper, and cooperating with the baffle plates erected on the hoppers, the moving side cut edges and the fixed side cut edges falling on the upper hopper and the lower hopper can be temporarily stored, so as to achieve normal production of steel plate edge cutting but without output; (3)The steel plate edge cutting output device of the present invention can conveniently control the synchronous retraction and extension of the two baffle plates through the cooperation of the air cylinder, the pressing wheel steel wire rope, the lower baffle plate, the upper and lower baffle plate connecting rod and the upper baffle plate. Combined with the design of the hoisting device, the fixed pulley device and the hoisting steel wire rope, the two states of steel plate edge cutting output / temporary storage can be quickly switched, greatly improving the efficiency of steel plate shearing output.

[0015] As one of the optional specific embodiments of the present invention, such as Figure 1As shown in the figure, the steel plate edge cutting output device includes a lower hopper 8 and an upper hopper 1 connected above it. It also includes a steel plate cutting head collecting hopper 19 located below the discharge outlets of the upper hopper 1 and the lower hopper 8. Baffles with a height of 100 mm are welded on both sides of the upper hopper 1 and the lower hopper 8. There is a non-overlapping area between the projection surface of the upper hopper 1 in the gravity direction and the projection surface of the lower hopper 8 in the gravity direction. In this embodiment, the projection area of the upper hopper 1 in the gravity direction is smaller than that of the lower hopper 8 in the gravity direction. The moving side cutting knife is located above the upper hopper 1, and the fixed side cutting knife is located above the left side of the lower hopper 8, so that the moving side edge cutting 17 and the fixed side edge cutting 18 freely fall onto the upper hopper 1 and the lower hopper 8 respectively. Upper baffle plates 2 and lower baffle plates 6 are respectively hinged at the discharge outlets of the upper hopper 1 and the lower hopper 8, and an upper and lower baffle plate connecting rod 3 is also hinged between the parallel upper baffle plates 2 and lower baffle plates 6, so that the upper baffle plates 2 and the lower baffle plates 6 deflect synchronously.

[0016] It can be understood that the upper and lower baffle plate connecting rod 3 described in the present invention can be either a rod or a long strip-shaped steel plate part, as long as the upper and lower ends are respectively hinged to the upper baffle plate 2 and the lower baffle plate 6.

[0017] In this embodiment, a cylinder 9 and a pressing wheel device 4 are further provided on the lower hopper 8. The telescopic end of the cylinder 9 is connected with a pressing wheel steel wire rope 5. The pressing wheel steel wire rope 5 passes through the pressing wheel device 4 and then is connected to the lower baffle plate 6. When the cylinder 9 retracts the pressing wheel steel wire rope 5, the lower baffle plate 6 deflects to the vertical state. When the cylinder 9 releases the pressing wheel steel wire rope 5, the lower baffle plate 6 deflects to the horizontal state. The bottom of the lower hopper 8 is hinged with a base, so that the lower hopper 8 can deflect at an angle around the lower hopper support point 7 on the base. The steel plate edge cutting output device also includes a hoisting device 10 and a fixed pulley device 11. The hoisting device 10 winds and unwinds a hoisting steel wire rope 12. The hoisting steel wire rope 12 passes through the fixed pulley device 11 and is connected to the lower hopper 8, so that the hoisting device 10 winds and unwinds the hoisting steel wire rope 12 to drive the lower hopper 8 to deflect on the base.

[0018] As Figure 2 shown, a lower edge cutting first guide plate 14 and a lower edge cutting second guide plate 16 are connected to the lower hopper 8, guiding the fixed side edge cutting 18 falling onto the lower hopper 8 to the discharge outlet of the lower hopper 8, and the discharge outlets of the lower hopper 8 and the upper hopper 1 do not overlap in the vertical direction.

[0019] The trimming on both sides of the steel plate is divided into a fixed trimming side 18 and a movable trimming side 17. The fixed side shredder breaks the fixed trimming side 18 into cut edges 250 mm long and then slides them onto the lower hopper 8 through the fixed trimming side chute 13, and finally falls into the inner side of one side of the steel plate cutting head collecting hopper 19. The output principle of the movable trimming side 17 is the same. The movable trimming side 17 slides onto the upper hopper 1 through the movable trimming side chute 15 and finally falls into the inner side of the other side of the steel plate cutting head collecting hopper 19. Among them, the fixed trimming side chute 13 and the movable trimming side chute 15 are respectively two discharge chute openings on the disk shearing machine.

[0020] Figure 3 This is a schematic diagram of the operation of the upper and lower layer baffle link 3 of the present invention. The hinge points of the upper baffle 2 and the lower baffle 6 are both on the left side, and both can deflect around their respective hinge points. The two ends of the upper and lower layer baffle link 3 are respectively hinged to the right sides of the upper baffle 2 and the lower baffle 6 to realize the linkage of the upper baffle 2 and the lower baffle 6. For example Figure 3 As shown, when pulling the press wheel wire rope 5 (the press wheel device 4 is not shown), the press wheel wire rope 5 pulls up the lower baffle 6 to deflect, and drives the upper baffle 2 to deflect synchronously through the linkage of the upper and lower layer baffle link 3, realizing the synchronous retraction of the upper baffle 2 and the lower baffle 6.

[0021] Specifically, in this embodiment, when it is necessary to hoist and replace the steel plate cutting head collecting hopper 19, the lower hopper 8 is placed in a horizontal position under the action of the hoisting device 10, the piston rod of the air cylinder 9 retracts, and the upper baffle 2 and the lower baffle 6 are in a vertical position under the pulling action of the press wheel wire rope 5 to prevent the cut edges from falling into the cut edge collecting pit, so as to ensure the normal progress of production. When the replacement of the steel plate cutting head collecting hopper 19 is completed, the lower hopper 8 is placed in a 30-degree slope position under the action of the hoisting device 10, the air cylinder 9 extends the piston rod to release the press wheel wire rope 5, and at the same time lowers the upper baffle 2 and the lower baffle 6, and the two side cut edges respectively slide smoothly into the steel plate cutting head collecting hopper 19.

[0022] The method for outputting the steel plate trimming by using the aforementioned steel plate trimming output device of the present invention includes: when the steel plate trimming is normally produced and output, the hoisting device 10 pulls up the hoisting wire rope 12 to control the lower hopper 8 to rotate and tilt around the lower hopper support point 7, raising the tail end of the lower hopper 8, and the air cylinder 9 releases the press wheel wire rope 5 to make the lower baffle 6 in a horizontal state or an inclined downward state. The movable trimming side 17 and the fixed trimming side 18 respectively free fall onto the inclined upper hopper 1 and lower hopper 8 and slide out from their respective discharge places; when the steel plate trimming is normally produced but not output, the hoisting device 10 releases the hoisting wire rope 12 to control the lower hopper 8 to rotate to a horizontal state around the lower hopper support point 7, and the air cylinder 9 retracts the press wheel wire rope 5 to make the lower baffle 6 retract to a vertical state. The movable trimming side 17 and the fixed trimming side 18 respectively free fall onto the horizontal upper hopper 1 and lower hopper 8 and are temporarily stored.

[0023] When the movable side cutting edge 17 and the fixed side cutting edge 18 respectively fall freely onto the upper hopper 1 and the lower hopper 8, the first guide plate 14 for the lower cutting edge and the second guide plate 16 for the lower cutting edge guide the fixed side cutting edge 18 falling onto the lower hopper 8 to the discharging place of the lower hopper 8, and the movable side cutting edges 17 and the fixed side cutting edges 18 of the upper hopper 1 and the lower hopper 8 are respectively output to different positions.

[0024] In addition to the above embodiments, the present invention may also have other embodiments. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
