Flying shear outlet guide groove for high-speed wire rod production

Abstract

The utility model relates to a flying shear outlet guide groove for high-speed wire rod production, and belongs to the technical field of flying shear outlet guide grooves. Comprising a guide groove body. According to the guide groove, the steel falling groove is matched with the inclined plate, when a sheared head is too short and the length of the sheared head cannot reach the second outlet, the sheared head can fall into the waste hopper through the steel falling groove at the moment, and therefore the phenomenon that the sheared head is left in the guide groove body to cause jamming to a rolled piece which normally passes subsequently is avoided. The steel falling groove provides enough falling space for the sheared head of the rolled piece, and the inclined plate can ensure that the sheared head falls in the inclined direction of the inclined plate. By arranging the small-size triangular guide, the length of an original triangular guide is shortened, and the risk that a rolled piece collides with the small-size triangular guide in the running process is effectively reduced. By arranging the transverse rollers, traditional sliding friction is changed into rolling friction, the friction resistance between a rolled piece and the bottom plate is effectively reduced, and abrasion is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of flying shear outlet guide grooves, in particular to a flying shear outlet guide groove for high-speed wire production. Background Art

[0002] The high-speed wire rod 800 shear primarily performs head trimming and shredding of rolled pieces. It is installed between the 18th pre-finishing mill and the 19th finishing mill. Its exit guide plays a crucial role in connecting the upper and lower sections. The guide has two exits: one for shearing the head of the rolled piece through the shredder and dropping it into the scrap hopper (exit two), and the other for directing the normal rolled piece after the head is cut off to the rolling line to maintain normal production (exit one). A switch is installed in front of the exit guide to change the running direction of the rolled piece. During operation of the switch, a servo motor drives the eccentric shaft through a reducer, causing the swing guide to swing back and forth horizontally with the input end shaft as its center, thereby swinging the rolled piece to two positions: the shearing position (the rolled piece's head is sheared by the 800 shear and then goes to exit two), and the rolling line position (the rolled piece with its head sheared goes to exit one).

[0003] During the high-speed wire rod production process, before the stock from the 18th pre-finishing mill passes through the 800 shear, the swing guide is positioned at the shearing station, awaiting the shearing head and facing Exit 2. The sheared head (1.0m-1.4m) passes through Exit 2, enters the shredder, and falls into the scrap hopper. Later, when the sheared stock passes through the 800 shear, the swing guide quickly swings to the rolling line, facing Exit 1, allowing the stock to be directed from Exit 1 to the 19th finishing mill, thus maintaining normal production.

[0004] However, in the actual rolling process, the sheared head of the workpiece may be too short, so that its length does not reach the second outlet. This will cause the sheared head to be retained inside the outlet guide groove, and then form a blockage for the workpiece that passes normally later, resulting in waste. In addition, during the operation of the workpiece, due to the difference in the swing speed of the swing guide, this inconsistency may cause the swing guide to be unable to completely swing the cut head workpiece to the position of the rolling line when passing through the 800 shear, and eventually cause the workpiece to collide with the triangular guide, resulting in waste. Finally, during the production process of the workpiece, sliding friction will be generated between the workpiece and the bottom plate of the traditional outlet guide groove. This continuous friction will not only scratch the workpiece itself, but also cause wear on the bottom plate of the outlet guide groove, further affecting production efficiency and product quality.

[0027] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] See also Figure 1-6The utility model provides a flying shear outlet guide groove for high-speed wire rod production, comprising a guide groove body 1, a trumpet-shaped steel inlet 11 is provided on the right side of the guide groove body 1, a bottom plate 12 is fixedly connected to the left side of the lower surface of the guide groove body 1, a steel drop groove 13 is penetrated and provided on the right side of the lower surface of the guide groove body 1, an inclined plate 2 is fixedly connected to the right side of the bottom plate 12 and on the left side of the steel drop groove 13, a transverse roller 3 is rotatably connected to the connection between the bottom plate 12 and the inclined plate 2, a steel outlet 14 is provided on the left side of the guide groove body 1, and the steel outlet 14 is divided into an outlet 1 5 to the finishing mill and an outlet 2 6 to the shredder by a small-size triangular guide 4, the outlet 1 5 is located in front of the small-size triangular guide 4, and the outlet 2 6 is located behind the small-size triangular guide 4.

[0029] The present invention utilizes the interaction between the steel drop chute 13 and the inclined plate 2. When a sheared head is too short to reach the outlet 2 6, it will fall through the steel drop chute 13 into the scrap hopper, preventing the sheared head from being retained within the guide chute body 1 and causing subsequent jamming of the workpiece. The steel drop chute 13 provides ample space for the sheared head to fall, while the inclined plate 2 ensures that the sheared head falls along the inclined direction of the inclined plate 2. This structure significantly improves production efficiency and reduces the risk of scrap caused by jamming.

[0030] By providing the small-sized triangular guide 4, the length of the original triangular guide is shortened, and the risk of collision between the rolled piece and the small-sized triangular guide 4 during operation is effectively reduced.

[0031] By setting the transverse roller 3, the rolled piece will contact the transverse roller 3 after entering the guide groove body 1, and drive the transverse roller 3 to rotate, changing the traditional sliding friction into rolling friction, effectively reducing the friction resistance between the rolled piece and the bottom plate 12, and reducing wear.

[0032] Furthermore, the groove length of the steel drop groove 13 is 750±10 mm.

[0033] Specifically, the steel drop trough 13 provides enough space for the sheared head to fall. The trough length is designed to be between 750±10mm, which can ensure that when the sheared head length does not reach the outlet 26, it can quickly fall from the steel drop trough 13.

[0034] Furthermore, the inclined angle of the inclined plate 2 is 60 degrees to 80 degrees.

[0035] Specifically, setting the angle of the inclined plate 2 at 60-80 degrees ensures that the sheared head slides smoothly during the drop process, preventing the sheared head from being stuck on the inclined plate 2 due to an improper angle. With a reasonable inclination angle, the sheared head can slide quickly and stably along the inclined plate 2 after being sheared, effectively preventing the jamming caused by the stuck head.

[0036] Furthermore, a through groove 21 for accommodating the transverse roller 3 is provided at the connection between the base plate 12 and the inclined plate 2. A C-shaped seat 31 is fixedly connected to the lower surface of the base plate 12 and one side close to the through groove 21. The transverse roller 3 is rotatably connected to the inside of the C-shaped seat 31, and the top end of the transverse roller 3 is higher than the upper surface of the base plate 12.

[0037] Specifically, when the workpiece contacts transverse roller 3, the top of transverse roller 3 is elevated above the upper surface of base plate 12, effectively preventing direct contact between the workpiece and base plate 12. This prevents friction between the workpiece and base plate 12, allowing smooth movement of the workpiece during transport and improving overall work efficiency. This structure not only reduces friction-induced wear on base plate 12, extending the service life of the equipment, but also prevents scratches on the workpiece, improving product quality.

[0038] Furthermore, the length of the small-sized triangular guide 4 is 55±5 mm.

[0039] Specifically, the length of the small-sized triangular guide 4 is set between 55±5 mm, which can provide sufficient swing space for the rolled piece as much as possible without affecting its original function, thereby avoiding the situation where the rolled piece does not swing in time during movement and collides with the small-sized triangular guide 4.

[0040] Furthermore, a mounting groove 41 is provided at the right tip of the small-sized triangular guide 4 , and a vertical roller 42 is rotatably connected inside the mounting groove 41 . The diameter of the vertical roller 42 is greater than the left length of the mounting groove 41 .

[0041] Specifically, when the head of the workpiece contacts the small triangular guide 4, it drives the vertical roller 42 to roll, thereby preventing friction between the workpiece and the head of the small triangular guide 4. Secondly, the diameter of the vertical roller 42 is larger than the left side length of the mounting groove 41. This design facilitates the transition of the workpiece from the vertical roller 42 to the sidewall of the small triangular guide 4. When the workpiece contacts the vertical roller 42, it drives the vertical roller 42 to roll. As the workpiece gradually transitions from the vertical roller 42 to the small triangular guide 4, if the diameter of the vertical roller 42 is smaller than the left side length of the mounting groove 41, the workpiece will become stuck in the mounting groove 41 during the transition, thus affecting production.

[0042] Furthermore, the front and rear inner side walls and the inner top wall of the guide groove body 1 are fixedly connected with multiple groups of reinforcing ribs 7.

[0043] Specifically, the reinforcing ribs 7 ensure the strength and rigidity of the guide channel body 1 and can effectively prevent the guide channel body 1 from being deformed in a high temperature environment.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
